Abstract

The utility model relates to the field of agricultural engineering, namely to the separating working bodies of potato harvesters. The goal is to increase productivity and improve the process of sieving the soil. This is achieved by the fact that the conveyor with rubberized blades made at an angle is located inside the separating elevator, is made with the possibility of rotation in the opposite direction of the elevator. By separating plant residues and large soil impurities on the bar screen and feeding them to the upper edge of the conveyor, the technological process of tuber separation will be greatly improved, resulting in an increase in productivity and an improvement in the process of sieving the soil.

Description

The utility model relates to the field of agricultural engineering, namely to the separating working bodies of potato harvesters.

Known separating the working body of potato harvesters, containing a transport drum with a guide plate and a separator installed inside the transport drum [1].

The disadvantage of this separating working body is that a lot of impurities come along with the tubers, which must be separated on subsequent working bodies, which complicates the technological process of the combine.

The closest solution in terms of technical essence is a separating elevator of a root and tuber harvester, including driving and driven rollers, flexible traction elements with transverse rods, on which cylindrical rigid covers are installed with a gap and the possibility of free movement around the rod, and under it there is a shaker made in the form of a spiral curved rod with the possibility of changing the frequency of rotation of the drum [2].

The disadvantage of the separating elevator of the root crop harvester is the low productivity and quality of soil sifting.

The goal is to increase productivity and improve the process of sieving the soil. This is achieved by the fact that the conveyor with rubberized blades made at an angle is located inside the separating elevator, is made with the possibility of rotation in the opposite direction of the elevator.

In FIG. 1 shows a separating working body of potato harvesters. The separating working body of potato harvesters includes a separating elevator 1, an internal conveyor 2 with rubberized blades 3.

The separating working body of potato harvesters works as follows.

The tuberous mass, previously separated on the working bodies of the lower belt of the combine, comes from the separating elevator 1 to the conveyor with rigid blades 2.

At the same time, tubers and soil clods, corresponding to their size, pass through the gaps of the bar grate 2 to the sorting surface, and large lumps, remains of tops and other vegetation are retained by the bars of the grate and removed along them by means of the blades of the conveying drum 3 to the upper edge of the conveyor. Rigid elevator blades clean the elevator from sticking, thereby improving the process of sieving the soil.

By separating plant residues and large soil impurities on the bar screen and feeding them to the upper edge of the conveyor, the technological process of tuber separation will be greatly improved, resulting in an increase in productivity and an improvement in the process of sieving the soil.
