Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to the working bodies of cotton pickers and cotton pickers.

The purpose of the invention is to stabilize the movement and increase the reliability of the working body, since an increase in the firing frequency of raising or lowering the working bodies leads to an increase in the frequency of operation of the hydraulic distributor and an increase in the power required for copying the relief of the working rows, and also other negative phenomena (increase in oil temperature in the hydraulic system, vibration of the machine’s working apparatus, etc.).

FIG. 1 shows a cotton-picking machine (first option); in fig. 2 shows section A-A in FIG. one; in fig. 3 - copier (the second option); in fig. 4 — chain bb in fig. 3

The copier of an agricultural machine, for example, a cotton harvesting machine, contains a working body 1, which copies the relief of the soil (Fig. 1 and 2), which is niaply installed by means of grids 2 and 3 relative to the element 4 of the frame of the cotton harvester. For the hinge installation 2 and 3 relative to the element 4 of the frame of the apparatus, horizontal axes 5 and 6 are used to ensure rotation of the rod in a vertical plane parallel to the direction of movement of the apparatus.

The copier is equipped with a stabilizing tool with oscillations of r 2 and 3, the ratchet 7 of which is installed on the axis 5 with a POSSIBLE SPINNING, relative to this axis. By its end, a ratchet is 7 yudzhat to an element 4 of the frame of the apparatus with a spring 8. To the serrated surface of the ratchet 7 it is pressed by a spring, 9 the pawl 10, is pivotally mounted on t ge 2 and is spring loaded} 1a for ensuring force interaction with the ratchet co.pane 7. Over leash - put the sensor 1 mounted on the element 12 of the frame. In the transport position, the ha 3 is supported on the frame element 13.

The device works in the following way.

When the machine is moving, the working body 1 touches the ground and monitors the change in its condition. 1: If a bump is encountered, the working body 1 is raised. T he 2 with the help of the dog C) turns the ratchet 7, eliminating friction between the end of the ratchet 7 and element 4 of the frame. The necessary frictional force is created by compressing the spring 8. T he 2 acts on the uiyn of the electric sensor 11, (giving a command to an electromagnet that acts on the rod of the radial valve controlling the hydraulic lift of the device (electromagnet, hydraulic distributor and hydraulic lift) (not shown). 1 free by your own

the weight drops down, the impact of the cable 2 on the sensor of the electric sensor 11 stops, the electromagnet releases the valve of the hydraulic distributor, and the device lowers to its original position. If there are small clumps of earth, the working body 1 either crushes them, or rises, but does not jump due to the presence of a certain amount of friction between the end of the ratchet 7 and the frame element 4.

Technical and economic advantages of the proposed device according to the first embodiment are as follows.

Due to the presence in the machine of a stabilizing device, the working body, for example, a bush lift, does not bounce when meeting with lumps of earth, but gradually rises or crushes lumps. The bush lift 1 acts on the soil with the minimum effort necessary to lower it. This makes it possible to reduce the power required to move the arinarate along the rows, to prevent the bush lifter from digging up on loose soil, to avoid its bush lift and clogging the working slot of the machine with earth. Stabilizing the movement of the shrub lift 1 reduces the frequency of operation of the hydraulic distributor controlling the hydraulic lift of the machine. Reducing the frequency of operation of the hydraulic distributor reduces the moshchnost spent by the hydraulic lift, i.e. the apparatus required for copying the soil relief, reduces the vibration of the apparatus and the temperature of the oil in the hydraulic system. The proposed design allows a spring lift to be unloaded on the soil, while avoiding the occurrence of self-oscillations.

Thus, the proposed device makes it possible to reduce the power required for the movement of the apparatus in series and to stop; the copying of the profile of the row by means of algorithms increases the reliability of operation and the agrotechnical indicators of the machine.

The copier of the agricultural machine according to the second variant, for example cotton harvesting, contains a harvesting machine 14 with supporting spherical rollers 15 suspended on t 16 (Figs. 3 and 4). Moreover, m-6 represents two shoulders with shoulders a and b a lever. The lever 16 forms a permanent connection with a horizontal axis 18. The shoulder b of the lever 16 through the spring 19 is connected with the rod of the hydraulic ram 20.

The copier is equipped with a stabilizing device, including a ratchet 2L mounted on the axis 18, with its end ratchet 21 pressed against the fixed frame element 22 by the spring 23. The dog 24 pivotally pressed onto the gear surface of the ratchet 21 is pivotally mounted on the shoulder of the lever 16.

Above the lever 16 is the sensor 25 mounted on the element 26 of the frame.

When the machine moves, the harvester 14 rests on the ground with supporting spherical rollers 15. Moreover, almost the entire weight of the apparatus 14 is perceived by the spring 19. If a small bump meets, the apparatus 14 is lifted due to the compression of the spring 19, while the lever 16 rotates the ratchet 21, overcoming friction between the ratchet end and the stationary element 22. The frictional force is created by compressing the spring 23. After passing a small mound, the device 14 under the action of an unbalanced part of its own weight freely skaets down. At the same time, possible self-oscillations due to the presence of a spring 19 in the system are quenched with a stabilizing device. If the depth of the deck is significantly increasedAA

In this case, the lever 16 presses on the w; pack of the electric sensor 25, which commands the electromagnet, which acts on the hydraulic distributor rod that controls the hydraulic lift 20 of the device 14 (electromagnet and hydraulic distributor are not shown). The hydraulic lift ram 20 lifts the device 14. The technical and economic advantages of the device according to the second variant compared with the known copiers is that the proposed device allows copying small uneven reliefs with the help of springs without self-oscillations. This achieves smoothness of copying, improvement of the agro-parameters of the apparatus, reduction of the power required for the implementation of copying the soil relief by the apparatus by reducing the frequency of operation of the hydraulic distributor and the hydraulic lift of the apparatus.
