MACHINE FOR PRELANDING PREPARATION OF SOIL

摘要

The invention relates to the agricultural industry, in particular, to machines for pre-preparation of the arable soil horizon to a combine harvesting potatoes. A drawback of the existing device is the low efficiency due to the crumbling of soil lumps that knives komkorazruschayuschego device in contact with the soil lumps are only partially destroying them, and their partially shifted in the driving direction. The purpose of the utility model is to improve the quality and purity of the destruction of lumps of tubers in a bunker harvester. This object is achieved in that to increase the efficiency of destruction of soil lumps designed screen comprising a rack mounted on the axle with the possibility of regulating the inclination angle of the screen in a vertical plane, wherein the screen has inclined protrusions for more efficient destruction of lumps and openings with a diameter d = 25 mm. The use of this utility model provides an opportunity to improve the quality and purity of destruction of lumps in the hopper tubers harvester.
