Description

The invention relates to potato harvesters, equipped with a grate conveyor-elevator, consisting of a number of tapes.

In the proposed potato harvester, for the purpose of better loosening of the earth, raised by the ploughshare and trapped on the conveyor, the latter is formed from a series of endless, alternately arranged ribbons - elongated, moving at one speed, and shortened, moving at a lower or higher speed ..

In FIG. 1 is a side view of a potato harvester; FIG. 2 - the same on top.

In most cases, when harvesting potatoes, the tops are lain, why a cutting device, such as a mower, is installed in front of the plowshare, and to lift the tops of the tops in front of the knives there is a fork 2 with three horns attached to the lower fixed knife, made one whole with it. The cutting part of the knives is located at a certain height and can be changed to one or the other height with the help of a lifting mechanism A. The shape of the horns makes it possible to break a clod of earth, which prevents the knives from clogging.

The cut tops of the tops are picked up by endless rakes 3 and retracted to the right side of the field, where when you turn the fingers on the roller 4, the leading part of the finger receives an accelerated motion (due to pressing the opposite end of the finger to the roller), thereby dropping the tops of the tops on the collector 5, which, as it accumulates, it rotates around axis 6 and drops the tops in a heap. The collector overturns is made by the driver from the control apparatus through a system of levers.

The land released from the tops is raised by the yellow-leaved ploughshare 7, and the entire mass of the land with tubers slides over the grid 8 of the feeder 9 with split blades. The feeder 9 raises the mass and brings it to the belt conveyor 10. The feeder blades pass between the grating crossbars and, having a curved back, allow smooth separation of the earth layer, which ensures weight gain without wounding the tubers. From the grill 8 above the feeder, the mass is taken up by the conveyor 10 ,. which consists of separate ribbons, with each row of fingers being riveted on each. The tapes are of various lengths and are arranged in a checkerboard pattern; the speed of movement of the long belts 11 is greater or less than that of the shortened belts 12, which has an intensive effect on loosening the soil without injuring the tubers.

The recovered mass moves along the grate 13c, which swings from the eccentric 14, where, thanks to the loosening of the earth by conveyor belts, the ground is worn out and collapses under the machine. The roots of the tops, due to the difference in speeds, are carried away by a long conveyor up to the cleaning roller 15, which ejects the roots from the machine. Potatoes from the grate 13 are transferred onto an oloboobraznuyu lattice 16, where it is advanced with the help of an ingrown wheel from the blade of the scraper 17 along the rotating grates 18. At the last pass through the lattice 16, the clay adheres to clay and so on.

The cleaned potatoes fall into H8 zholoby 19 and are fed to the bucket elevator 20, which feeds the potato to the sorting box 22 with three wooden sieves 24, suspended from the frame of the MACHINE on the wooden strings 23, which ensure the ease of quality movement. Placed in a three-sieve box, sorts into three varieties are provided. The sieves are made of compiled wooden "Lanoch", with the upper sieve having openings along the cracker, thanks to which it will be possible to get sharp edges of potato varieties, since the coincidence of the swing and the clearances makes it possible to extract smaller potatoes from a larger amount. The second sieve is disposed across the roll, which makes it possible to further strengthen the border of the variety from a smaller amount. The location of the sieves, as well as their inclination, can be changed depending on the size of the potatoes being excavated. Potato sieve 24 is sent to the tolob in any container: bags, baskets, drawers or trailers.

The subject matter of the invention.

The potato harvesting machine with a grate and an elevator conveyor is made of a series of belts, characterized in that the conveyor 10 is composed of various lengths of endless belts arranged in such a way that between the two elongated belts II one shortened 12 is located, moreover, for a better loosening of the earth, the velocity of elongated tapes are more or less than the speed of movement shortened.
