Description

00 O)

The invention relates to agricultural machinery, in particular to bridge units for agricultural work, for example, during growing and harvesting.

The pavement is known. The unit for agricultural work, containing a two-console farm, mounted on parallel-arranged supports with a drive, which are placed on rail tracks, as well as a linkage mechanism connected to the farm {lj.

However, this unit can be used in a limited area, the width of which is somewhat larger than the track width of the EEOS rails.

The closest to the invention according to the technical essence and the achieved result is a pavement aggregate for agricultural work, containing parallel tracks of rail tracks, pillow supports placed on them, on which a two-console truss is installed with a device for hanging working members. A known aggregate can move with one treatment area to another by maneuvering along transverse rail tracks m pj.

However, a known aggregate is transferred from one gauge to another only at the end of the training site, which reduces the maneuverability of the gregat in the conditions of work on the agricultural land with unprofitable relief, for example, skew, in which conditions the cross-rail track is difficult. All this leads to a decrease in the performance of the unit.

The purpose of the invention is to increase the productivity by increasing the aneurorability of the aggregate during the processing of agricultural plots with varying relief. .

The goal is achieved by the fact that in a bridge unit for agricultural work containing parallel rails of the El tracks, placed on them are supports with a drive, on which a two-console truss with a device for hanging working bodies is installed, each support is provided with a carriage connected to it by means of a lifting mechanism and the truss is freely mounted on the carriages and is connected with them through the mechanism for moving it perpendicular to the direction of movement of the aggregate, and each bearing has a lock relative to elsovyh ways. .

In addition, each carriage is provided with a sensor for activating its lifting mechanism, which is located in a plane passing through the longitudinal axis of the truss at the interface with the carriage.

FIG. 1 shows the proposed bridge unit, front view; in fig. 2 - the same, top view; on FIG. 3 - the same, side view; 4 shows a support with a truss; in fig. 5 and 6 fragment of the support with the carriage and various options for lifting mechanisms; 7 - sensor

The bridge unit for agricultural works contains a two-console farm 1, parallel supports 2, with | {abraded by a drive 3 moving across rail tracks 4, which are fixed on the base 5. Rail tracks 4 are located along the section to be treated, and each adjacent to it on a variable relief section b also has rail tracks 4 with parallel ras-. put supports. On farm 1, p) are installed, 7 for napping up the working organs 3 for agricultural work. The fixture 7 is mounted on the truss with the possibility of dragging along its longitudinal axis 9. Kazeda support 2 is provided with a carriage 10 connected to it via a lifting mechanism. The lifting mechanism can have various versions, including in the form of a cable-block system 11 or a screw gear 12. Carriage 10 it is connected with the farm T through the mechanism of displacement of the latter in a direction perpendicular to the movement of the aggregate. The movement mechanism can be made in the form of rollers 13 spanning the truss. The lifting mechanism is driven from the engine 14, and the rollers 13 from the engine 15. Each support is provided with a latch relative to the rail tracks 4. The latch can be made in the form of an uphill gripper 16, crepe rail 4 and the carriages 10 are mounted, the sensors 17 enable their lifting mechanism. The sensor 17 is installed in a plane passing through the longitudinal axis of the truss in the place of its interface with the carriage 10, and consists of a lever 18, a limit switch 19 electrically connected to the engine 14. The length a of each console of the truss 1 is equal to or greater than the distance b between rail tracks 1/1 and 4.

 The bridge unit operates as follows.

When processing a plot, for example, a meadow garden, farm 1 on two supports 2 moves along rail tracks 4. This provides for synchronous movement of supports 2. If 5 it is necessary to move the truss with

By working bodies at the Neighboring site b, both supports 2 of this section are moved along rail tracks and installed in the alignment with supports 2 of the treated section. All the supports 2 are fixed by the grippers 16, raise the carriages 10 together with the farm 1 to the extreme upper position, turn on the engine of the mechanism for moving the floor 1. The carriage 13 of the mechanism, the movement, rotating, moves the farm 1 to the nearest rapor 2 of the adjacent section 6, whereby the lever 18 of the sensor 17 rises and turns on the engine 14 of the carriage raising mechanism 10 when in contact with the farm 1 when the sensor is triggered 17. Then the truss moves further with the rollers 13 of the support 2 of the adjacent section 6 to the second support of this section. In the process of moving the truss from the treated area to the neighboring one, its equilibrium is ensured by moving the device 7 with the working bodies 8 along the truss in the direction opposite to 5 of the extended console of the truss. After the truss has been installed at the required position on the supports 2 of the neighboring section b, the unit is ready for work on this section. Moving farm 1 to a neighboring plot can be done anywhere on the farmland. Movement 1 across the track on supports

5 allows the processing of adjacent areas located at different levels of variable relief, for example, in the form of kosogor, ravines, slopes, which increases the headlining of the bridge unit, and hence its performance.
