    An agricultural machine displaceable in a predetermined travel direction and having relative thereto a plurality of forwardly extending arms forming forwardly open throats for receiving respective rows of a crop during harvesting thereof has a position-detecting system comprising a feeler pivoted about an upright axis underneath each of the arms. Each feeler is an elastically flexible plate carried on a rigid arm connected to the respective pivot and each plate has a pair of lateral edges each exposed in front of a respective one of the throats flanking the respective plate. The feelers are all mechanically connected for joint pivoting by a common link that is connected to a signal generator in turn connected to the steering system of the agricultural machine.

    one
    The invention relates to a device for controlling the progress of the harvesting machine along rows of plants, especially when harvesting corn, with the help of sensitive elements mounted on a variety of corn harvesting equipment.
    To control the progress of the harvesting machine along the plantations, various replicating devices are known, copying, as described, for example, in DT-OS 2434396, both sides of a row of plants. When this occurs, the copying of the line of a row of plantings, the programming of the optimal line using a computer and. signaling to hydraulic control system.
    Such single-sided copying, however, is associated with some drawbacks, especially noticeable when cleaning irregular plantings. The use of these systems causes high costs due to the need to use a computer capable of collecting and processing extensive information.
    This is required in order to limit to the minimum possible the rotation of the steering gear and to prevent it from being too fast a variable load.
    The next drawback is that the entire system goes out of order when one of the sensitive elements breaks down. This can also occur in the event of a clogged feed channel, in which
    5 sensitive elements begin to adhere to both sides of the channel. In the event of an accident of one of the sensitive elements, such a system loses its performance, as a result of which automatic control is out of order. The possibility of such accidents can be reduced by using several copying devices, but this entails a significant increase in costs. Another disadvantage is that it is always necessary to use a new special device for harvesting corn for different widths of inter-spacing. It is not universally applicable to the same defined range of interstices such a device. Use
    20, the usual variety of maize harvesting equipment for different inter-row widths is possible only after a complicated changeover.
    The purpose of the invention is to create a device with which one could copy several rows of plants and which would be applied to different widths of plants between the rows. The invention is based on the task of creating for a series of devices used for harvesting corn, a device that would set up an average value for a copier of plants, allow it to be easily changed to different widths of crop and would be inexpensive to produce. According to the invention, this is achieved by the fact that a sensitive element is located on a row of devices for harvesting corn behind the tip of each divider, on at least two adjacent dividers. At the same time, the mutual, predominantly asymmetric with respect to the tip of the divider, the location of these sensitive elements on the crossbar of the divider is chosen so that for each copy, its edge has different sides of the rows. The movable axis is placed in its supports with an inclination forward in the direction of movement of the harvesting machine. Due to this, the sensing elements can return to their normal position under the influence of their own mass. The end of the connecting rod is connected to the sensor, transmitting to it the deflection of the connecting rod from its normal position to the hydraulic steering system of the steering mechanism. The normal position of the connecting rod is provided by the spring system in all those cases when the sensing elements move through the rows of plants without meeting too much resistance. The distance between the dividers is designed so that the inclusion of different width between the rows, in a certain range, can occur without a mark growing along the edges of the stalks. The location of the sensing elements is chosen so that they are coaxial with respect to the feed, its channel and at the same distance in front of the cutting device. Their maximum width is equal to or less than the minimum width between the rows. This is achieved by the fact that the sensing elements, on the one hand, are arranged asymmetrically on the dividers on its tip, and on the other hand, have copy surfaces of different widths. Such an arrangement is only conditional, since the sensitive elements on the left and right sides protrude beyond the edge of the separator, due to which, for example, the right side copies the smaller one and the left side the greater width of the rows. Sensitive elements are made of flexible material, and their sides are rigid. During the seizure of plant divisors, the stems move along the tips to the sensing elements and put pressure on them in the opposite direction to the stem. The connecting rod, connected to the lever, transmits the deviation from the normal position to the sensor. The sensor transmits this value mainly through electrical wires to the hydraulic system of the steering mechanism, regulating, thereby, turning it so that the sensitive elements can return to their normal position. Due to the presence of several sensing elements, they are set to an average value through such a connection, as a result of which a number of corn harvesting devices can choose the path of least resistance. This especially facilitates harvesting plants that are poorly seeded in rows, as well as incision in the headland, as this reduces the losses caused by pitted traces. Due to the fact that the sensing elements are made of flexible material, they can bend upwards when confronted with obstacles, thereby eliminating the risk of damage to the copying device. After the passage of the obstacle, the sensing element again takes its original form. The flat configuration of sensing elements allows the machine to move in plantations and on the reverse, without jamming the stems in the copying device. Another advantage of this device is its simple design, since it guarantees high control accuracy even without a computer. At the same time, it provides high productivity with minimal labor demand, which contributes significantly to the increase in the load of the straw cutter. FIG. 1 depicts a series of maize harvesting attachments, top view; in fig. 2 shows the layout of the sensitive elements on a row of maize harvesting equipment; in fig. 3 is a diagram of a sensitive element with transmission units. At the bottom of the corn harvesting device 1 there is a divider 2 with a tip 3 divider. Behind the tip 3, the sensitive element 4 is horizontally rotated on the support 5. With the help of the lever b, the sensitive element 4 is pivotally connected to the connecting rod 7. The sensitive element 4 consists of a copying edge 8 and 9 and a surface 10 with a cross member 11, to which it adjoins extension 12 with a movable axis GZ and 14 on the support 5. Support 5 is designed in such a way that the movable axis 13 is slightly tilted forward. Due to this, the sensitive elements 4 return to their original position under the influence of their own mass. Cutting device 1 is coaxially located behind sensitive elements 4. When a stalk is seized with a tip of a divider, 3 stems slid along the copy edge 8 cause horizontal deflection of sensitive elements 4 relative to the support 14. Through the lever 6, the stop of the sensitive element 4 is transmitted to the connecting rod 7, and from there to sensor 15. Sensor 15 transmits a signal to the hydraulic system of the steering mechanism that performs steering correction. For returning the rotated connecting rod 7 to its normal position from the opposite side of the connecting rod 7 in both directions of movement, there is provided with one release spring 16.
