Abstract

Usage: in agricultural machinery engineering, in particular in castor-bean harvesting machines. SUMMARY OF THE INVENTION: The garbage harvester is equipped with a device 10 for destroying bolls on tretinki. In the stripping apparatus, the castor bean boxes are separated from the plant stalks, the main part of the boxes is spilled onto the transport board and fed to the cleaning of the boxes, where the heaps of boxes are separated from the litter. The boxes are then conveyed by the conveyor 7 to the device 10, where they fall into a narrowing gap between the fixed disk 11 and the rotating disk 12. Under the action of the elastic surface of the disk 12 and the resulting centrifugal force of the box, they roll over the elastic surface of the disk 11 to break into trikes and are thrown into the annular casing 13. 2 silt

Description

The invention relates to agricultural machinery, in particular to casting machines.

The known design of a combine for cleaning castor beans, including the reaping part, shelling apparatus, keyboard straw walker, seed cleaning, seed conveyors and intact bolls.

The disadvantages of such a combine are low productivity and significant crushing of castor beans.

The closest technical solution chosen as a prototype is a beef harvester, which contains the harvesting part of the harvester, the cleaning of the bolls, the straw walker, the conveyor, the loading device, the peeling block and the seed conveyors.

A disadvantage of the known design is the low productivity of the combine and significant damage to castor bean seeds, since during its operation in the shelling and separating unit the boxes are continuously mixed from the cleaning and tretinka, obtained after the boxes are destroyed when they pass through the shelling unit and returned to heal the seeds The efficiency of the peeling process of such a mixture of bolls and tretinki is significantly reduced due to the difference in their geometric dimensions and the limited elasticity of the working organs of the shelling apparatus and leads to repeated skipping (circulation) of the tretinki through the shelling apparatus until their destruction.

The aim of the invention is to increase the productivity of the combine and reduce damage to castor seeds, by eliminating the circulation of the heap in the shelling and separating unit

This goal is achieved by the fact that, in the known construction of a combine comprising a reaping part, a puller, a device for cleaning bolls, a straw walker, a conveyor of bolls with a loading device, a shelling and separating unit and seed conveyors, a device is installed for breaking the boxes on tretinki which is placed in the boot device and made in the form of rubberized corrugated discs, the discs are located at an acute angle to one another, one of the discs is fixed, and the other is rigidly connected n with the screw shaft boot device.

FIG. 1 shows a general view of the pick-and-pick combine in longitudinal section; FIG. 2 is a section A-A of FIG. one.

The harvester includes a reaping part 1, a stripping apparatus 2, under which transport board 3 is located and cleaning the boxes 4. Behind the combing device 2, there is a keyboard straw walker with 5, directly behind which is a chopper of stalks 6. Cleaning the boxes 4 is connected by a conveyor 7 and a loading device 8 with a shelling and separating unit 9. At the unloading end of the loading device 8, a device 10 is installed to break up the castor boxes on tretizki consisting of a fixed inclined rubberized th disk 11, rotating disk 12 and the rubber ring 13 of the housing.

The shelling and separation unit 9 includes a sieve for cleaning the seeds 14, the beginning of which is connected by a channel 15 to a device 10 for destroying the bolls on tretinki. Above the sieve 14, there is an aspiration on the chamber of the exhausters 16, and under it there is an unloading auger 17. Behind the sieve 14 there is a shelling device 18, the output of which is connected by a guide casing 19 with the beginning of the sieve 14, the auger 17 is connected to the seed bin 20 by a pneumatic actuator 21 .

The agile harvester operates as follows. During the movement of the combine, the castor plants are cut off by the reaping part 1 and fed to the entrance of the combing device 2, where the castor boxes are separated from the plant stalks. The main part of the bolls wakes up in the combing unit 2 on the transport board 3 and is fed to the cleaning of the bollards 4. Plant stems and a small part of the bolls are fed by the combing device 2 to the straw walker 5, where the bolls are released, and the bales are cleaned to the bollards 4. Plant stalks straw stalk transported

5 to the chopper of the stalks 6, where they are crushed and scattered across the field. In cleaning the boxes 4, a pile of boxes is separated from small litter, leaves, cuttings, etc., which are thrown on the field, and the castor boxes are supplied by the conveyor 7 and the loading device 8 to the shelling and separating unit 9.

In the boot device 8 boxes

0 is moved to the device 10 to destroy the boxes on the tretizki, where they fall into the narrowing gap between the fixed disk 11 and the rotating disk 12. Under the action of the elastic surface of the rotating disk 12 and the resulting centrifugal force of the box rolls over the elastic surface of the stationary disk 11, they collapse tretinki and are thrown into the annular casing 13. From the casing 13, the tretinka arrive at the beginning of the sieve 14 through a special channel 15 and are transported to a shelling device 18. where the husking of the seeds from retinok. 18 shelling seeds from shelling machine

5 and the fruit casings, as well as small debris, are guided along the guide casing 19 at the beginning of the sieve 14. When moving through the sieve 14, the seeds pass through the holes in it and enter the discharge screw 17, from where into the pneumatic conduit 21 and are transported into the seed bunker 20. Fruits of seeds, fine debris is sucked off from the sieve by the 14 aspiration chamber of exhausters 16.

Proposed Harvesting

5, a combine with a device for destroying boxes on tretinki eliminates the circulation of boxes and tretinks in the shelling and separating unit, which leads to an increase in the productivity of the combine and

0 reduction of damage to seeds.

Claims (1)
