Description

1

The invention relates to agricultural machinery, namely, to bridging aggregates for performing various agricultural works with the use of replaceable tools, as well as to bridging aggregates performing sprinkling and pouring,

There are known multi-span electrified frontal sprinkling machines (for example, of the Kuban type), having a directional direction stabilization system, interacting with a cable tensioned along the channel edge, which serves to maintain a given course by automatically correcting it, as well as an automatic synchronization system for the movement of self-propelled supports at. passages in the forward and reverse directions.

The disadvantage of such devices is that the directional stabilization system does not provide the necessary stabilization of the wheels on the threads of the once laid and rolled gauges of the multi-track supporting base: when the vehicle passes the wheel, the self-propelled carts with the original gauges come off, the gauges are enlarged, the plants are trampled .

A device for controlling the mbstov agricultural unit is known, which contains contactless sensors mounted on self-propelled supports of the bridge unit, interacting with a system of reference frames fixed in the concrete of hard ruts laid along the ground by an agrogod.

The disadvantage of such a device is that it can be realized only if there are hard ruts on the agrogoddy, in the body of which the reference frames can be fixed, and the fastening of the rappers by their full penetration into the thread of the rolled ground gauge does not ensure the reliability of the bridge unit operation (since, For example, the soil falling on the repertoires fully buried in the ground increases the gap between the proximity sensor and the recessed recess embedded in the ground, and automatic cleaning of rappers is difficult).

The purpose of the invention is to improve the accuracy of the passage of the wheels of the bridge unit along the threads of a multi-line support track by maintaining the linearity of the front of movement of the bridge unit by aligning with the rappers attached to the ground surface of the agrogod.

The device contains a yoke 1, mounted on self-propelled trolleys 2, the lower ends of which interact with the support frames, made in the form of rails 3, mounted on elastic elements 4 and placed on the surface

5 soil tracks 5, with the rocker arms secured on the trolleys 2 using horizontal axes b with spring-loaded springs 7 with eccentric cams 8, and the upper ends of the rocker arms 1 interact with the rods of 9 sensors 10. The crossbars 3 reference frames are fixed on the U-shaped bases 11 with support plates. Limiting depth of penetration. Elastic elements 4 can be

5 is made in the form of springs 13 or rubber rods 14 reinforced from above with synthetic fabric, or rubber tubes 15. The compression of the springs 7 acting on the cams 8 is adjusted by nuts 16 through

0 sliding sleeves 17. The crossbar 3 of the bench mark can be equipped with a broadening rod 18 (Fig. 6), and folding arms 19 can be attached to the crossbar via hinges 20 (Fig. 7).

5 Fig.8-10 shows an example of mounting the device on a bridge assembly with a rigid multi-support farm — on an agro-bridge that performs agricultural work using interchangeable agricultural tools, where the rocker arms 1 and sensors

10 are located on rods 21 mounted on hubs of wheels 22 of self-propelled support trolleys 23. Along the lower edge of the cheeks 24 of multi-support truss 25, guides are fixed along which wheels 26 are driven by gear motors 27 fed by tires 28 running along the truss . The agro-bridge can have one or several platforms 29 with agricultural implements (not shown). The wheels 22 of the support carriages are driven by the electric motors 30 through the cardans 31 and the angular worm gearboxes 32. The belts 33 and 34 of the longitudinal conveyors deliver the crop removed from the agricultural net loaded with the inclined conveyors 35 and 36 k. marginal section 37, from where the crop is transported by auxiliary transport; position 38 denotes a hard edge thread with guide rails 39 for wheels.

Figures 11-13 show an example of mounting the device on a sprinkler, where the water distribution pipe 40 performs the role of a flexible multi-support farm of a stand-alone unit, with an edge technological section 41. The yoke 1 and the sensor 10 are fixed on the yoke 42 connecting the wheels 22 support carts. The lateral position of such bridge units, widely used as multi-span electrifying sprinklers, is stabilized by known devices, bypassing rigid concrete track with guide rollers and consisting of tensioned wire 43 and lateral spring-loaded rods 44. Position 45 denotes the open water conduit, and the position 46 - hydrants, if the water supply is provided by a closed water pressure channel.

The device works as follows.

With the approach of the agro-bridge (Figures 8-10) to the support frame, the rocker arm 1 whose lower end is lowered to the desired height is taken out by the crossbar 3 from the vertical position and the upper end of the rocker arm releases the spring-loaded rod 9, which then moves down and opens the contacts sensor 10, which is a signal for stopping the trolley. In the same way, as they approach their supporting ramps, other trolleys equipped with rocker arms stop, resulting in the device’s truss aligning itself in a strictly linear fashion if before that. The inertia was broken. In the presence of a rigid multi-support truss 25, set support frames on each thread no track

necessities and benchmarks can be supplied, for example, through two dirt tracks, as shown in FIG. 10. After all the support carriages have stopped along farm 25, platform 29 begins to move with agricultural implements fixed on it and to carry out the planned type of agricultural work. When the multi-support truss is equipped with three movable platforms 29 for processing the agro year, similar to that shown in FIG. 10, each of the platforms performs, for example, harvesting of root crops from its section located between the wheels with ground bench markers, while the rolled ground tracks with the bench markers remain intact, uncultivated. After the wheels pass over the benchmarks, they self-repair by the force of elastic elements. When the agro-bridge is used in the continuous frontal movement mode, the rows of frames are used as intermediate lines for controlling and leveling the front linearity.

The presence of a hard track 38 with guide rails 39 prevents parallel support of all support wheels of the agro-bridge in parallel, and this, together with the use of a control device on the rotors, ensures the stability of the passage of the wheels of the agro-bridge over the wheels. For example, using portable steel wire strung in the right places. The legs of the benchmarks are buried in the ground by strikes or by pressing on the bar 12. When, in order to increase the reliability of the agro-bridge on soils with poor bearing capacity, some of the tracks are hard from supporting plates on the ground that do not contain any other benchmarks built into them. systems (ferro-reporters, radiation and others), the support frames with elevated crossbar 3 can be placed in the right places on the ground next to rigid plates.

The linearity of the front of the multi-support sprinkler (Figures 11-13) is achieved in a similar way. The machine moves forward after the last run of the trolley stops, aligning the front, and when an electrical device (not shown) gives the command to move the aligned bridge aggregate forward. In this case, the magnitude of the parallel transverse shear of all wheels is determined only by the accuracy of the stabilization device with a wire 43,

The positive effect of the device lies in the fact that the soil support frames improve the accuracy of the passage of the wheels of the bridge assembly along the threads of the multi-track support track by maintaining the linearity of the front of the bridge assembly by aligning the frames attached to the soil surface; ground support benchmarks make it possible to reduce the cost of engineering agro-equipment — do without rigid intermediate ruts where the soil quality allows the use of bridge aggregates without the laying of hard ruts, as well as where the hard ruts are laid, but for one reason or another They do not have other structures built into their body.
