Description

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

According to the main author. St. No. 294577 known 5 uproot-grinder, including a frame, a grinding drum with an unloading pipe, counter-rotating corrugated rollers with guides and pairwise mounted loosening legs [1]. 10

However, in such a tiller-shredder, loosening the soil around the root zone of the plant is not enough to pull out the stems as a whole, and cutting of the roots by the working organs does not occur because of the small width of capture of these organs. Therefore, the root part of the stem, bending around both the right and left loosening legs, remains unrooted in the soil.

In addition, there is also a breakage of 20 stems at the clamping point by corrugated rollers, resulting in a high stubble remaining after processing. An increase in the width of the gripping of these loosening paws leads to a significant increase in the traction resistance of the machine.

The purpose of the invention is to increase the efficiency of uprooting cotton stalks.

This goal is achieved by the fact that each loosening paw is equipped with a working body that removes the soil, and its working edge is zigzag. The soil scavenging organ is made in the form of a concave plate directed upward relative to the plane of the loosening paw and fixed in its end part at an angle relative to the direction of movement of the uprooter.

In FIG. 1 schematically shows a pulverizer-grinder, rear view; in FIG. 2 - the same, top view; in FIG. 3 — section A — A of FIG. 2.

The stalk grinder of cotton stalks contains a chopping drum with an unloading pipe (not shown in the drawings), counter-rotating feeding screw-grooved rollers 1, under which there are loosening legs 2 with working edges 3. The latter are made in a zigzag shape and installed with the formation of a passage 4 for plant roots , and at the end of the paws are fixed at an angle relative to the direction of movement of the uprooter, soil-discharging organs 5.

When the machine moves along the rows, the stalks of cotton fall between the feed rollers 1, where they are caught by the screws and fed into the chopping drum. With further movement along the rollers due to the fact that the root part of the stems is located with a deviation from its axis, it falls under the influence of the working edges 3 of the left or right paw

2. In this case, the root is shifted toward the center, and then into a zigzag passage, where it performs a series of transverse β-displacements. As a result of the displacements, the connection of the root with the soil is broken, and it is removed from the soil by the corrugated part of the rollers 1 with a break in the thinned part at a depth of 30-35 cm.

The soil coming from the ridge to the surface of the paw 2, when the machine moves, moves towards the unscrewing organ 5 and moves along the surface of the latter into the furrow, and thus the field surface is leveled.

The use of the proposed root stalk eliminator increases the efficiency of uprooting of stems, allows to extract stems with whole roots by simultaneously loosening the soil in the root zone and vibrating the root of the cotton stalks.
