Description

I

The invention relates to the field of agricultural engineering and can be used in the design of cotton harvesting machines.

It is known to adapt to a cotton-harvesting apparatus for catching cottonseed containing catchers in the form of rotors with an elastic surface mounted behind spindle drums 1.

The disadvantage of this device is that it is not able to remove cotton from the surface of the ridge and slopes of the pile. This reduces the completeness of the cotton harvest by the apparatus.

The aim of the invention is to increase the completeness of the cotton harvest.

The goal is achieved by the fact that, in the proposed adaptation, the rotors are located obliquely across the direction of movement of the apparatus and have a concave surface encompassing the outer contour of the rear part of the spindle drum.

FIG. 1 shows a cotton harvester, rear view; in fig. 2 - the same, top view; in fig. 3 shows the relative position of the spindle of the drum and the gripping element of the elastic roller.

Cotton harvester contains front 1 and rear 2 pairs of spindle

drums with rotating spindles 3 and pullers 4. On the frame of the spindle drums, behind them, are installed rotors 5 that rotate in bearings and have a headset 6 mounted on them, for example, serrate, serrated or another. Drive elastic rotors 5 receive from a large gear 7 spindle drum through a small gear 8, propeller telescopic shaft 9 and a bevel gear 10, on the output shaft of which is installed

elastic rotors 5. The housing of the bevel gearbox is rigidly connected to the adjusting screw 11, on which the adjusting nut 12 is placed. abutting with one plane into the fixed stop 13, rigidly fixed on the frame of the spindle unit. The axis of the rotors 5 is inclined across the direction of movement of the apparatus, and the surface of the rotors is made concave so that in horizontal projection it covers the outer contour of the rear part of the spindle drum 2.

Cotton-harvesting app:;) At works as follows.

When the cotton harvester moves across the field, the front 1 and rear 2 pairs of spindle drums process the cotton bush, remove the xjOnKa raw part of the spindle 3, and use the puller 4 to transfer the collected cotton to the receiving and transport pneumatic system.

At the same time, in the first and second collections elastic vras, ayushies rotors 5 install. in position II (Fig. 1) above the surface of the pile.

The bulk of the raw cotton falls to the ground when the cotton bush leaves the working area of the last pair of spindle drums and hits the exciting elements of the headset 6 elastic rotating rotors 5. Then the cotton caught on the rotor 5 ,. is transferred to spindle drum 2 where the rotating spindles intercept the cotton (Figs. 2 and 3) and carry it to the puller 4, etc.

When working the same} on the harvester at the third assembly, when between the front 1 and rear 2 pairs of spindle drums there is a device for crushing kurak (), the elastic rotors 5 are shifted to position 1 (Fig. 1) before contact with the ground dki.

This is done by moving the screw 11 down, turning the nut 12, resting on the fixed stop 13. Moving down, the screw 11 moves the rotor 5 to the lower position (together with the gearbox 10) and the movable part of the telescopic cardan shaft 9.

Rolling over the pile, the elastic rotors copy the profile of the ridge and with the help of exciting elements they pick up cotton lying on the surface of the ridge. In addition, on the elastic rotors, the cotton falls on the lower bolls of the cotton bush, not caught by the spindle drums. After exiting from the working zone of the last pair of 2 spindle drums, the straightening branches of the cotton bush fall on the surface of elastic rotors 5. Cotton slices fall freely on the surface of elastic rotors when the bush leaves the working zone of the last pair of spindle drums.

All the cotton caught on the surface of the elastic rotor 5 is held on it by means of the exciting elements of the headset 6 and, as the rotor 5 rotates, it is transferred to the rapidly rotating spindle m, which intercepts the cotton slices from the rotor 5 (Fig. 3) and carries them to the pullers 4, etc.

In order for the interaction of spindle drum 2 and elastic rotor 5 to facilitate the most complete and high-quality cotton removal, the surface of the rotor (Fig. 2 and 3) has a curvilinear configuration, and the curvature radius Ri of the forming rotor surface is greater than the radius R of the spindle drum at the external spindle points. Elastic rotors rotate in the direction of rotation of the drive wheels of the cotton picker.

The installation behind the last pair of spindle drums of elastic rotating rotors allows to increase the completeness of the collection of raw cotton in both the first and subsequent collections due to the capture and additional collection and selection of that part of the raw cotton that falls on the ground in the well-known cotton pickers.
