    The hydrostatic drive is for the drawing-in rollers of a forage harvester. The upper drawing-in roller may be lifted out, for adjustment to suit different densities of crop. Spur wheel transmissions (7, 11), positioned above each other, are connected to the upper (10) and lower drawing-in rollers (14) on one side of the cutting unit. The spur wheels associated witt the upper and lower rollers each engage with a drive pinion of a hydraulic motor (5, 6). The motors are mounted by flanges to the transmission shaft parallel to the drawing-in rollers, and are driven in the series by the output of a pump.

    (54) DEVICE OF HYDROSTATIC DRIVE FOR NUTRITIONAL SELF-PROPERTY FIELD BODIES
    Shredder
    one
    The invention relates to agricultural machines, in particular, to a hydrostatic drive device for feeders of a self-propelled field grinder, in which the feeders are created from roller and / or chain systems.
    For the forced capture of the material to be harvested and the feed to the cutting bodies, the lower and upper feeding bodies are used. At the same time, the upper supplying bodies in order to adapt to the different thickness of the layer in the supply channel are made lifting.
    Field grinders are known, where the drive of the upper and lower feeder bodies is carried out by transmission through transfer elements, such as chains or pivot shafts. If chain gears are used as the drive means, they should be so arranged as to ensure that the upper feed bodies can be raised and the lower feed bodies rotate in the opposite direction. When using hinged shafts, while simultaneously rotating, the height-lift of the upper feed elements is easily overcome.
    However, the drive of the pivot shafts must be carried out from a gear located to the side of the feeder bodies. But because
    5, the length of the hinged shafts is determined by the required lifting height of the feeder bodies; a suitable space for mounting the gear is required on the side of the grinding unit.
    “This space is available only with low throughput field shredders. The total width of the maschina is limited by the tolerance for open road traffic. In addition, the acceleration and deceleration of the supply of the harvested material is possible only with the help of a complex mechanical feed with stepless regulation.

    Claims (2)
    [1]
    With another known drive from the junction box, the upper feed rolls are driven by a hinge shaft and a closed spur gear. In this case, the cylindrical gear body is designed as a rocker between the pressing roller and the pressing roller. The drive of the lower pair of rolls is carried out from the transfer of the opposite side of the grinding unit. The disadvantages of this drive are the need for space for the gearbox. It should be noted that the construction space required for such implementations is not available for field shredders with a large pickup width. A further disadvantage is that with chains moving in an oil bath, as is the case with closed chain drives, chain tensioning is possible only with the help of complex devices. Outside, it is not possible to recognize the necessity of tensioning the chains. Another known device has for driving the feeders two impressed on the transmission of the hydraulic engine. This eliminates steplessly adjustable mechanical transmissions and the powering bodies have a better chance of acceleration and deceleration, due to which it is possible to set up the feed rate and therefore the length of the pulverized mass. However, as a result of the arrangement of the hydraulic motors on the transfer unit, the powering units must be driven via gear or chain drives and articulated shafts. To ensure the hydraulic drive of all feeders, this device requires a complex angular belt drive, a drive shaft passing through the machine and several pulleys. The ability of the upper feeder bodies to be lifted for various thicknesses of the layers is also realized through the articulated shafts. The purpose of the invention is to create a drive system for feeding bodies of a self-propelled field grinder, in which all feeding bodies can be realized with the help of a hydrostatic drive, without additional angle belt drives, drive shafts, etc., with the highest possible lift of the upper feeders, a small overall width and minimum wear of the drive elements, for this it is necessary to arrange the economical size of the drive unit so that both the upper and lower feeding organs are driven from one side, moreover, reversibility and the corresponding need for power distribution to the upper and lower feed rolls should be achieved. The goal is achieved by having cylindrical gears arranged one above the other on the same side of the grinding unit at the upper feed rolls and at the lower feed rolls. In the upper cylindrical gear, the cylindrical gears of the upper feed rolls are meshed with the drive gear flanged by a cylindrical gear of the hydraulic motor, and in the lower cylindrical gear the cylindrical gears of the lower feed rolls interact with the drive bristle of the second hydraulic motor. Both hydraulic motors are fixed parallel to the axes of their feed rolls directly on the corresponding cylindrical gear. However, it is also possible that in the case of intermediate engagement of a conic pair, the hydraulic motor will be located with a deviation from the parallel arrangement of the axes, in any position on the cylindrical gear. This arrangement, despite the extra conical pair, offers the advantage that the hydraulic motor can be placed on a cylindrical gear with savings in place. The hydraulic motors are driven by a junction box located in the frame of the junction box that drives the auxiliary hydraulic pump. From the auxiliary hydraulic pump, the upper feed rolls are provided as primary through the hydraulic pipes and the lower feed rolls as secondary by means of hydraulic motors. At the same time, with such a drive, stepless or stepwise control of the feed rate and reversibility of the upper and lower feed rolls is achieved. These series-connected hydraulic elements offer the advantage that it is possible to meet the needs of the distribution of power to the upper and lower feed rolls. Along with the possibility of infinitely variable adjustment of the length of the ground mass, smooth reversibility of the drive is also realized. In cylindrical gears between the upper and lower feed rolls and hydraulic motors, the cylindrical gears of the respective feed rolls are made with a gear ratio relative to the drive gear and hydraulic motors corresponding to the roll diameter. Thanks to these respective roll diameters, the same speed of all the feed rolls is achieved by a gear ratio and a uniform feed rate of the material to be harvested becomes possible. The support of the cylindrical gears in the cylindrical gears is designed simultaneously as a support for the respective feed rolls, so that only the support on the opposite side of the feed rolls is needed. FIG. 1 shows a field chopper, top view; in fig. 2 - feeding organs, side view; in fig. 3 - the same, a section along the axes of the upper feeding rolls; in fig. 4 is a schematic representation of a drive; in fig. 5 is a drive system wiring diagram. In the frame of the self-propelled field chipper frame 1, an auxiliary hydraulic pump 2 is located, driven at a constant speed from the junction box 3. From the auxiliary hydraulic pump 2 through the hydraulic conduit 4, 4 and 4 in series and with synchronous drive, is driven as the primary hydraulic motor . 5, and the secondary hydraulic motor 6. The hydraulic motor 5 is engaged in the cylindrical gear 7 through the drive gear 8 with the spur gears 9, and 9 of the upper feed rolls X and 10. The hydraulic motor 6 interacts in the second cylindrical gear AND through drive gear 12 with spur gears 13 and 13 of the lower feed rolls 14 and 14. Both cylindrical gears 7 and 11 are attached in oil-proof design to hydraulic motors 5 and b, flanges parallel along the axis to the feed rolls 10, 10, 14 and 14. The support of the cylindrical gears 9, 9, 13 and 13 simultaneously supports the feed rolls 10, 10, 14 and 14, so that, including opposite bearing arms 15 and bearings 16 and 16c by hydraulic motors 5 and 6 and cylindrical gears 7 and 11, for the upper feed rolls 10 and 10 and the lower feed rolls 14, 14, two closed assemblies are formed. In order for the upper feed rollers 10, 10 to rise, depending on the layer thickness of the cleaning material supplied to the grinding unit, the side walls 17 and 17 of the grinding unit have longitudinal slots 15 and 18. In these longitudinal slots 18 and 18, the upper feeds rolls 10 and 10 and, biased, rises to the top. The hydraulic piping 4, 4 and 4 leading to the hydraulic motors 5 and 6 are located in the grinding unit so that they can follow the up and down movements of the upper feed rollers 10 and 10 of the hydraulic motor 5 to set the pressure rolls 10 and 10 and returning them to their original position on both sides between the side walls 17, 17 and the node of the upper feeding rolls 10 and 10 are tensioned springs 19. In another embodiment, between the hydraulic motor 5 and secured in a cylindrical A transmission gear 7 is provided with a bevel gear pair. This achieves the fact that for a hydraulic motor 5 there is no need for an arrangement parallel to the axes of the cylindrical gear 7, and, due to space saving, it can be located at the corresponding position of the conical pair next to or under the cylindrical gear 7. This arrangement can also be achieved lower feed rolls 14 and 14 by intermediately turning on the taper pair at the hydraulic motor 6. FIG. 5 shows a connection diagram for a hydraulic drive. From the auxiliary hydraulic pump 2, the regulated flow of oil through the hydraulic pipe 4 and the distribution hydraulic box 20 containing valves to ensure circulation is supplied to the hydraulic engine 5. Through the hydraulic pipe 4, the hydraulic motors 5 and 6 are connected in series through the hydraulic pipe 4 junction box 20 flows back to auxiliary hydraulic pump 2. Replenishment of working fluid leaks and cooling a closed cycle is accomplished is by means of an injection pump built into the hydraulic pump 2, which sucks the working fluid through the filter 21 from the hydraulic tank 22. The working fluid flow caused by leaks and flushing flows back from the hydraulic motors 5 and 6 to the distribution hydraulic box 20 and the hydraulic pump 2 passes through the oil cooler 23 and then flows back into the hydraulic tank 22.
