Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. Its peculiarity is that the spindle 1 is complete with screw thread 2 on the base with the formation of working parts from two ends, the cutting cavities engage with the projections 6 of the fixed disk 5, which encompasses the shaft 4 with rotation-reciprocating movement. spindle. At the same time, one of its working ends is in the cotton pick-up area 18, and the other in the pick-off area 11. This makes it possible to reduce the metal consumption by a factor of 2, and to increase the efficiency of the apparatus by eliminating the reverse. 3il. & (Pu & 2 A-A 00 4; 00 with th

Description

The invention relates to agricultural machinery and can be used cotton harvesting machines.

The aim of the invention is to increase the efficiency of the cotton-picking machine, increase the cotton's breathtaking ability, eliminate injuries to the green bolls, improve the raw cotton while reducing the metal intensity of the machine.

Figure 1 shows the working body of the cotton harvester, a view in plan in figure 2 is a section aa in figure 1; figure 3 - section bb in figure 2.

The device includes a runner-mounted spindles 1 with a screw thread 2, mounted in sleeves-directions x 3, located diametrically on the shaft 4.

Concentric to the shaft 4 there is a fixed disk 5 with protrusions 6, which form a helical gear with depressions 7, causing the spindle 1 of each torsa to rotate with simultaneous translational motion toward the cotton bushes.

The device is bounded by a perforated shield 8, in the slots 9 of which the spindles 1 enter with raw cotton trapped on the working surface. The shield 8 is adjoined by a slotted puller 10, by means of which it is possible to remove cotton from spindles and discharge it into the receiving chamber 11.

When the shaft 4 rotates, the spindles 1 take different positions 12 - 17j when each spindle is embedded in a compressed cotton bush - area 18, under the influence of its reaction forces, the end of 19 spindle 1 is position 20 due to gaps in kinematic pairs.

The device works as follows.

When the machine is moving in cotton rows, the shaft 4 rotates synchronously or with some advance in relation to the working speed of the cotton harvester, while the spindle 1 simultaneously rotates the rotational-translational movements, one end (position

12 - 17) spindle 1 in the collection zone 18 penetrates deep into cotton bushes, mashes and extracts raw cotton from the boxes. Progressive movement in the opposite direction of the spindle 1 and removal of the cotton begins when it comes into contact with the puller 10 in the area of the receiving chamber 11. The puller 10 can be used for picking cotton, for example a slit type (figure 1).

or disc puller type. The spindles are mounted in such a way that one end of the spindle 1 is in the cotton harvesting zone 18, and the other end in the cotton removal zone 11. The proposed design of the working body simplifies the design of the machine, increases the efficiency of cotton picking and reduces the metal content.
