Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular cotton harvesting machines.

The purpose of the invention is to increase the efficiency of picking cotton.

FIG. the apparatus is shown, a general view; n and fig. 2 shows a drum device in FIG. 3 - cotton grip element; in fig. 4 is a section A-A in FIG. 2

The cotton harvester has a frame 1 on which drums with shafts 2 are fastened to form a working slot in a horizontal position, each shaft 2, each shaft 2 arranged in a staggered order except for a row of holes for accommodating clapper elements 3 closest to the frame spiral guide 4, protruding forward and clearance 2, encompassing the gap. Direction of spiral

4 can be either right or left, 25 ° - cotton grip elements 3,

depending on the location of the drum relative to the cotton bush. In the gap between the shaft 2 and the guide 4, there is a pneumatic tubing for removing cotton 5.

The number of drums and their location on frame 1 is determined by the convenience of processing the cotton bush. Changing the location of the drums can be accomplished by making their attachment points in the frame of grooves (not shown) located along axis 6. Depending on the conditions of cotton harvesting on frame 1, they can be installed on the sides and in the center of two or three drums. To improve the processing conditions of cotton bushes, frame 1 is equipped with an inclination device 7.

The cotton grip element 3 is a hemispherical plastic or metal brush consisting of needle hooks 8, the number of which is determined depending on the efficiency of their capture of cotton fibers. The hooks 8 are fastened to the heads 9 connected to the radially mounted rods 10. In the lower part of each rod 10 there is a holder 11 in which the roller 12 is made, for example, in the form of a spring-loaded ball. The head 9 is in glass 13 and is connected to it by means of longitudinal

guides 14 along which it can move along the axis of the glass 13.

Between the bottom of the cup 13 and the holder 11 there is a spring 15 which presses the roller 12 of the grip element 3 to the fixed central cam 16 rigidly connected to the frame 1. On one side the cam 16 has an oval longitudinal profile. On top of the glass 13 is closed by the cotton plate 17 and is installed in the hole-slot of the drum-shaft 2 in the bearing 18.

located in one longitudinal row of the shaft 2. In the glasses 1 nearest to the frame 13 additional gears 22 are fastened (the frame is shown by dotted lines). They interact with face disc 23, I have on one side slanting.

The disk 23 is rigidly connected to the shaft 2. In order for the additional gears 22 to interact with the disk 23, the holes closest to the frame 1 of the jack of the grip elements 3 are located on the shaft 2 not in a checkerboard pattern, but in the same plane. The spiral guide 4 is fixed on the cover 24 of the shaft 2 rigidly. To enable rotation, shaft 2 is mounted on a fixed cam 16 by means of bearings 25.

The drive drum is made in the form of a chain 26 connected to the power unit of the vehicle through a speed synchronizer (not shown). The chain 26 interacts with the gear 27, which through the studs 28, leading the B to move the drum. In the branch pipe 5 of cotton removal, which can be performed with an internal screw sensor, a vacuum is created to transport cotton fibers to the hopper through a pipe: 29. The collector box must be installed against the profiled side of the central cam 16.

Cotton harvester works as follows.

Frame 1 is mounted on a vehicle, such as a tractor. There are drums on frame 1, the number and placement of which in the grooves along axis 6 depend on the level at which cotton boxes matured on the cotton bushes. The drums are installed in such a way that the box of the cotton-picking machine 5 is on the side opposite to the one on which the cotton fibers will be removed from the bush. If necessary, the frame 1 using the device 7 sets the desired slope.

The drive of the drums through the synchronizer is connected to the power unit of the vehicle. The vehicle moves across the field so that the row of cotton bushes passes in the gap between the drums. Due to the operation of the drive chain 26 connected through a synchronizer to the vehicle power unit, the drum 2 through gear 27 and stud 28 rotates in bearings 25 around a fixed central cam 16, wherein the cotton grip elements 3 are rotated from the disk 23 through additional gears 22, gears 20 and closed chains 21,

The right or left direction of rotation of the shaft 2 is set depending on the direction of the thread of the spiral guide 4. When the shaft 2 rotates, the guide 4 enters between the side branches and the inside of the cotton bush. At the same time, they bring closer and hold the cotton branches near the shaft 2, the synchronizer provides the condition under which the interaction of the guide 4 with the cotton bush is coordinated with the speed of the vehicle, i.e., the twisting and cutting of the branches do not occur. The hemispherical brushes of the cotton gripping elements 3, by rotating, cling 8 cotton fibers with their hooks and release them from the cotton boxes.

When the shaft rotates, 2 rollers 12 of the lifting elements 3 move from round to the profiled oval side of the central cam 16. Under the action of the spring 15

4544

The rod 10 with the head 9 is lowered, which carries the hooks 8 behind it. In this case, the plate 17 releases the hooks 8 from the cotton fibers. Since the thickness h of the cotton picker 17 is selected to be larger than the h value of the oval sample in the cam 16, when lowering into the channels 19, the needle hooks 8 cannot exit

of these, under the bottom of the cotton picker 17, the release of cotton fibers from the hooks 8 takes place under the duct of the nozzle 5 and under the action of vacuum the fibers are transported through pipe 29- to the collecting bin of the vehicle.

The proposed cotton harvester improves the quality of the collection of raw cotton due to the fact that

cotton fibers are only slightly wound onto the bars of cotton elements, and then, before being transported into the bunker, they are completely freed from them and ensures

the greater completeness of the collection of raw cotton from cotton bushes due to the fact that, thanks to the spiral guide, the drums can freely penetrate into the inner part of cotton bushes,.
