Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, devices for harvesting crops at the root.

According to the main author. St. No. 959669 a device for threshing agricultural crops at the root is known, which contains inclined combing conveyors with teeth fixed at chains at an angle to their contour, equipped with an additional asterisk installed below the main ones, as well as a drive and a receiving chamber, with the branches of the chains between the lower ones and additional asterisks of the conveyors are inclined, and the teeth on these branches are parallel to the surface of the floor. In addition, additional sprockets are installed at the ends of the two shoulders driving levers.

A disadvantage of the known device is the loss of grain. They arise because a part of the grains released by the interaction of the teeth with the heads does not acquire the direction and speed of movement to ensure the throwing of the towing products into the collection, as a result of which some of them do not reach the main collection and fall to the surface.

The purpose of the invention is to reduce grain losses during the harvesting of brown, wilted and laid plants.

This goal is achieved by the fact that the known device for threshing agricultural crops at the root is equipped with a grain collector-collector installed in front of the receiving chamber.

In addition, the grain collector is equipped with a mechanism for adjusting its position in height.

The adjustment mechanism can be made in the form of a hydraulic cylinder.

FIG. 1 shows a device in a position for cleaning long-straw, many brown, drooping and laid plants, side view; in fig. 2 - the same, in the position for cleaning upright plants.

The device contains endless chains 1 on which combs 2, consisting of flat combing teeth, are fastened. A flexible tape 3 is attached to the chains, the purpose of which is to transport the product of the tow and prevent it from spilling

comb to the floor surface. Chains mounted on three stars 4-6. Lower 5 and additional 6 asterisks are mounted on the movable two-armed arms rye 7, which is hingedly attached to the frame 8. The position of the lower 5 and additional 6 stars is changed by a hydraulic cylinder 9 fixed to the frame 8 and the movable two-armed lever 7. At the front of the receiving chamber wall 10 a leveling collection catcher 11 of grain is installed with an unloading device 12 and an adjustment mechanism made in the form of a hydraulic cylinder 13.

During the operation of the device, when cleaning the brown, drooping and laid down plants, an additional asterisk 6 is placed in a position in which the teeth on the additional branch move parallel to the floor surface, enter the stem with minimal force and sweep the plants. At the same time, part of the selected grains, which have a low flight speed, which do not allow them to reach the main collection, are collected in a leveling collection-catcher 11 of grain. When cleaning the pristine steblesto

5, the leveling collection catcher i is positioned by the hydraulic cylinder 13 to the position in which it bends the stems by the action of its outer cylindrical surface. At the same time, the long stems entering under the leveling collection-catcher 11, at the time of slipping out from under it, deviate a greater distance from the base than the short ones. As a result of different limb stalks of different lengths, the spike is aligned in height. In addition, a smooth (without shock) gliding of the stems along the surface of the leveling collector-catcher 11 virtually eliminates the knocking out of the grains from the ears before they enter the tow.

Thus, the presence of height-adjustable, depending on the state of the steble-leveling collector harvested, allows to reduce grain losses when harvesting by stripping at the root of brown, drooping and dead trees.

agricultural crops.
