    [0001] The present invention relates to a machine for harvesting roots planted in soil in rows, such as beets, and a harvesting method provided for such a machine. To harvest rows of roots aligned along longitudinal rows, when they reach maturity, in particular for the harvesting of sugar beets, a known type of machine, presented in particular by the document EP-B1-1772050, comprises a set disposed at the front of a motorized tractor, comprising successively from the front, guide wheels, a leaf stripping unit of the bulk of the leaves, a horizontal cutting unit of the beet heads to eliminate the remaining leaves and scalping the beetroot, and a harvesting unit that digs the soil beneath the beets to extract them, remove the soil, and move them back to a storage medium. In the rest of this document, the term beetroot will encompass all types of roots that can be harvested with these machines. The cutting unit of the beet head comprises for each row a horizontal cutting blade, comprising just in front a guide in height or cam, having parallel bars forming a curve rising towards the front so as to slide on the top beet to be cut, which ends up a little bit above the blade. For each row of beets, the cutting unit is mounted on a substantially balanced support that allows up and down the guide bearing successively on the top of each beet. In this way, the next back blade being adjusted a little below this guide, horizontally cuts the beet just below its top. The harvesting unit according to this cutting unit also comprises a height positioning linked to the level of the cutting blade, so as to dig the soil according to a predefined height with respect to the cutting level. This gives an optimization of the soil digging depth, for beets with a standard height. However, this type of automatic adjustment of the level of the harvesting unit is not optimized in all cases. Especially if the beets are smaller with a reduced height, or if there is an absence of sugar beet, the soil will be dug too deeply or unnecessarily, with excessive fuel consumption to power the machine. Conversely if the beets are larger with a higher height, then there is a risk of damaging their bases and losing part of the harvest because we have not dug deep enough. The present invention is intended to avoid these disadvantages of the prior art. It proposes for this purpose a machine for harvesting roots planted in earth and aligned in rows, comprising a horizontal cutting unit of the root head having means for automatically adjusting the level of its cutting blade according to the level of this head, which is followed by a harvest unit digging the soil below the roots at a relative height below the cutting level, characterized in that it comprises a means for detecting the height of the top of the head. root and the duration of passage of a cutting guide on this vertex, and a means for adjusting the relative height of the harvesting unit relative to the cutting level, according to this height and this duration of passage on the summit. An advantage of this harvesting machine and that according to the height of the top of the root indicated by the means for detecting the height, and the size indicated by the duration of passage, extended when these roots are larger and reduced when they are smaller, we can easily deduce indications of their size and then optimally adjust the harvesting unit to the depth just needed. This ensures an optimum digging of the soil that reduces fuel consumption by digging less deeply when the beet is high, and reduces the risk of damaging the roots by digging deeper when the beet is deep. The root harvesting machine according to the invention may further comprise one or more of the following features, which may be combined with each other.
    [0002] Advantageously, the means for detecting the passage time on the top of the root comprises a means which detects the force or the deformation of the support of the cutting blade of the cutting unit, which is flexible. This type of sensor gives a simple way of indicating the duration of passage of the cutting head on each root. In this case, the blade of the cutting unit can be mounted on a parallelogram, giving during the passage of the cutting guide on the root a movement of this parallelogram which is measured by an angle sensor. During the rise time of the parallelogram, one thus locates both the height of the beet and the size of the top of the beet. Advantageously, the means for adjusting the relative height of the harvesting unit comprises a hydraulic jack controlled by an electronic control unit. Hydraulic cylinders developing high forces, allow high acceleration giving good dynamics.
    [0003] Advantageously, the harvesting machine comprises a device allowing the driver to predefine for each row an average level of the harvesting unit before its automatic adjustment by the adjustment means. The race to be performed for the adjustment of the relative height of the harvesting unit is thus reduced on average.
    [0004] Advantageously, each harvesting unit comprises a height sensor. It is thus possible to adjust its height by a closed-loop regulation. The invention also relates to a method of operating a root-planted and row-aligned root harvesting machine comprising a horizontal root-level cutting unit having an automatic level adjustment means. of its cutting blade according to the level of this head, which is followed by a harvesting unit digging the soil below the roots at a relative height below the cutting level, this method realizing a detection of the transit time on the root by the cutting unit, then an adjustment of the relative height of the harvesting unit with respect to the cutting level, according to this passage time.
    [0005] Advantageously, the operating method comprises a preliminary step of presetting the average level of the harvesting unit. Advantageously, from the average relative height, for a duration of passage over the important root, the operating method 5 increases this relative height, for an average time it keeps this relative height, and for a short time it reduces this relative height. Advantageously, in the absence of root detected, the operating method puts the relative height to a minimum. The invention will be better understood and other features and advantages will appear more clearly on reading the following description given by way of example, with reference to the appended drawings in which: FIG. 1 is a sectional view longitudinal of a beet planted in the soil, ready for harvest; Figures 2a, 2b and 2c are cross-sectional views of six rows of beets corresponding to the cutting width of a harvesting machine; - Figure 3 is a side view of a harvesting machine according to the invention; Figure 4 is a cross-sectional view of the harvesting units of this machine; - Figure 5 shows the operation of this machine in a longitudinal sectional view of a row of beets; and FIG. 6 shows, on the same sectional view, the gain in depth of digging brought by the harvesting machine. It should be noted that the following diagrams and explanations are based on a six-row harvesting machine. The invention applies in the same way to harvesting machines adapted to a lower or higher number of rows. In particular, the higher the number of rows torn off, the greater the benefits of the invention will be important. Indeed, the inequalities of the land and beets are greater over eight, nine or twelve rows than six. Optimizing the depth of the harvest level of each row will therefore result in increased profit.
    [0006] Figure 1 shows a beet 2 buried in the soil with a surface level 6, which has reached maturity must be harvested. For harvesting, the top of the beet 2 must first be cut horizontally according to the cutting level 12 located slightly below its vertex 4, in order to eliminate the leaves growing on this beet. The cutting of the top of the beet 4 then leaves a cutting plane of width L, which depends on the size of this beet. The harvesting machine according to the prior art, having automatic cutting level adjustment means, has a guide in front of the cutting blade which follows the upper contour of the beets 2 as it moves forward, in order to obtain the placement of the blade at the correct cutting level 12. The level of harvesting in the soil 8 represents the ideal level of digging the soil to harvest the beet 2, coming just below its main volume. Too deep digging unnecessarily consumes more energy to motorize the harvesting machine, and drives too much soil with beets 2, while digging that is not deep enough can damage these beets. For each beet, a relative height H is obtained between the cutting plane 12 and the harvesting level 8, which can vary within the same rank depending on numerous parameters, including in particular the local quality of the soil. , the degree of humidity, the longitudinal space between two beets, the degree of burial of this beet, and the specific yield for each beet. FIGS. 2a, 2b and 2c show different possible deformations of the cultivation field which extend longitudinally over the whole of this field, in six rows of beets which are harvested at the same time. The straight line 22 represents the overall inclination of the harvesting machine, the upper curve 6 the level of the soil surface, and the lower curve 8 the desired harvest level individually adjusted by rank, corresponding to the base of lateral blades 60 from the harvest unit coming to dig the soil just under each beet.
    [0007] Figure 2a shows a cross section of the soil surface 6 which is curved, the harvest level 8 of rows two to five must be raised. Figure 2b shows a cross-section of the soil surface 6 which falls on the right side, for example at the edge of a field, the crop machine being inclined. The harvest level 8 of rows two to four must be raised, that of rank six lowered. Figure 2c shows a cross-section of the soil surface 6 including a space 20 between rows two and three which has been tamped by the passage of a machine, forming a rail. Harvest level 8 of rows two and three must be lowered. FIG. 3 shows a harvesting machine comprising, at the front, two independent guide wheels 30 intended to follow the rows of beets, which are connected to the whole machine by articulated arms 32 each having a position sensor 34 sends a signal to the electronic control unit 54. The guide wheels 34 make it possible to determine the straight line 22 representing the overall inclination of the harvesting machine, the individual harvesting levels of each row 8 being determined with respect to this right. Then there is a leaf stripping unit which removes most of the beet leaves. Six transverse transversely aligned beet heads 36 are then provided, each comprising upstream of the horizontal cutting blade, a forwardly curved guide means slidable on the top of each beet to adjust height of this blade located just behind. The predefined height of the cutting unit 36 is measured by a sensor 38. Each cutting unit 36 comprises a guide and a cutting blade 30 mounted on a deformable parallelogram provided with an angle sensor 40, which makes it possible to measure the relative height of the guide during its passage on the beet 2, and therefore the height of the top 4 of this beet. This angle sensor 40 also makes it possible to measure the duration during which the guide and the cutting blade are raised, which makes it possible to deduce the size of the beet 2. The height information of the cutting unit 36 and Deformation of the parallelogram 40 is sent to the electronic control unit 54. Thus, over time, a succession of signals is obtained giving, by knowing the speed of advance of the harvesting machine, the indication of the width of each beet by measuring with the angle sensor 40, the duration of rise of the parallelogram, and the indication of the height of the top of the beet 4 from the inclination of this parallelogram. Beet 36, a harvesting unit 48 comprising a wheel having, on each side, the succession of blades 60 which dig the ground just below each beet in order to tear them off, and to send them back to the beet The six harvest units 48 each have a predefined mean level with respect to the harvesting machine, adjusted by a jack 44 as a function of the position of the stripper 35. For each row of beets the driver can predefine according to the overall condition of the soil surface 6 of that row, as shown in FIGS. 2a, 2b and 2c, the average level of each harvesting unit 48. Each unit harvesting machine 48 has more than one independent hydraulic cylinder 50 for modifying its height with respect to its predefined mean height, adding or subtracting a small value to give a relative height 25 aj ustable H, which is controlled by hydraulic valves 56 controlled by the electronic control unit 54. According to all the information received, in particular those given by the angle sensor 40 indicating the duration and the height, the unit The electronic control system 54 reacts very rapidly to precisely adjust the relative height H, in order to obtain the right level of harvest 8 adapted to each beet 2 that has just been cut.
    [0008] As a variant, the cutting detection of the beet can comprise a different measurement means, such as a pressure or effort sensor, a physical probe, a scanner in several dimensions or a three-dimensional camera.
    [0009] FIG. 5 shows the sectional level curve given by the angle sensor 40, and the signal 80 sent by this sensor, comprising rectangles indicating the absence of lifting of the parallelogram holding the cutting blade, and spaces L between these rectangles indicating the time of passage on the beet by the guide of the cutting blade.
    [0010] The strategy adopted is as follows, illustrated by lots of beet comprising successively starting from the left side of the drawing, a first batch 70, a second batch 72, a third batch 74, a fourth batch 76 and a space left empty 78. lot 70, the beets 2 are large and their top is at the middle level of the soil. These characteristics are detected by the angle sensor 40 of the parallelogram of the cutting blade, and a time of passage on the important beet. The relative height H is increased so as to be sure not to damage the base of this beet. For lot 72, beets are large and have grown out of the ground. These characteristics are detected by the angle sensor 40 of the parallelogram of the cutting blade, and a time of passage on the beet. The relative height H is also important, but as the beet top height is high, the harvest unit will be raised from its average position.
    [0011] In the case of lot 76, we have small beets, which have grown relatively above ground level. The harvesting unit will therefore be raised to take account of a relatively low height H and a top of the beet that is high. For any beet detected, corresponding to an absence of detection by the angle sensor 40, the relative height H is set to minimum. This characteristic is presented by empty space 78. FIG. 6 shows a black surface corresponding to the difference in height between a constant harvest level 90 used by harvesting machines according to the prior art, and the harvest level. 8 optimized with the method according to the invention. There is at the same time an absence of damage to the beets 2, and an adjustment of this level of harvest 8 to the highest possible, translating a saving of energy for the tractive force of the machine, and a smaller amount of soil carried away. unnecessarily.
