Description

one

The invention relates to the field of agricultural engineering and can be used in devices for harvesting and chopping cotton stalks.

Known for upropper chopper stalks of cotton, containing installed in the casing with the receiving chamber of the rotor with the hinged mounted on it the holder of the knives 1.

A disadvantage of the prior art grabber is frequent breakdowns in the loading system, since the upper part of the stem, located under the rollers, is cut at the moment of entering the grinding chamber and completely thrown into the loader. The length of these cuts often reaches 350-500 mm, while the diameter of the loader pipe does not usually exceed 250-270 mm.

In addition, to ensure that the stems enter the chopping chamber, a large part of the front wall of the receiving chamber is open, which reduces the ability of the rotor to force air into the loader tube to transport the crushed mass to the cart. Increasing the number of rotor revolutions does not lead to the elimination of this deficiency and is economically unprofitable, since the air consumption in the engine increases insignificantly and

power is growing very significantly.

The aim of the invention is to improve the quality of grinding and the elimination of faces. This goal is achieved by the fact that the holder of each knife is provided with an end wall fixed on the side of the receiving chamber perpendicular to the rotor axis and having a knife grinding in the direction of rotation of the rotor.

FIG. 1 shows the proposed shredder-chopper, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - shredder, side view.

The shredder includes a rotor with hinged holders of the knives 1, on the end of which from the side of the receiving chamber 2 there is a side wall 3, perpendicular to their generators.

The rotor rotates in a casing having a receiving chamber 2 in the front part. Under the receiving chamber 2 there are mounted auger rolls 4, which capture and feed loosened

writhing paws 5 cotton stalks. The shredded stems are ejected through the guide tube of the loader 6. The side walls 3 are mounted for

increasing the air flow in the loader 6,

elimination of faces, as well as for better grinding ..., „.. ,, ,,,.,.

The front side during rotation of the rotor of the side wall is sharpened 7. The side wall 3 with sharpening 7 performs additional cutting of the side branches and the upper part of the stems entering the receiving chamber 2 in an inclined state under the influence of auger rolls 4.

The technological process of the work of uproot-grinder is as follows.

During the movement of the grader-grader along rows, cotton bushes are captured by the auger part of rollers 4 and move along their axis to the grooved surface. At this time, with a writhing paw 5, the soil is loosened in the zone of the root system of the stems and displaced them along the working edge of the paw until it is completely uprooted. When the stems enter the grooved area of the rollers 4, they are fed up into the chopper.

The blades of the rotor 1 stalks are crushed and

Transfer to transportation.

Sharpening 7 ,,. On the side wall of the 3 holder

aids finer grinding

and eliminates the slaughter in the bootloader.
