Abstract

The invention relates to agriculture. The purpose of the invention is to reduce energy intensity, simplify the design. The shaking mechanism of the separating device is made in the form of guides 6 located under the rods of the working branch of the bar elevator and between the supporting stops in the form of spring plates 7 placed on the sides of the elevator. Each plate 7 has a wave-like guide track with a sinusoidal profile facing the free ends bars. During operation of the device, separation of any tuberous layer is ensured. 1 s.p. flowers, 6 ill.

Description

The invention relates to agriculture.

The aim of the invention is to reduce the energy intensity of separation at different conditions of the tuberous formation and simplify the design.

Figure 1 shows the proposed device, side view; figure 2 is the same, a top view; Figures 3-6 are diagrams of the interaction of the tuberous layer at different positions of the rods relative to the shaking mechanism.

The separating device of the tuber harvesting machine contains a series of digging plowshares 1, a bar elevator 2 and an unloading conveyor 3. On the sides of the elevator 2 above the free ends of the rods 4 of its working branch there is a shaking mechanism 5 with supporting stops. The shaking mechanism is made in the form of guides 6, which are located under the rods 4 of the working branch of the bar elevator and between the supporting stops. The stops are made in the form of supporting plates 7 located on the lateral sides of the elevator, each of which has a wave-like guide track with a sinusoidal profile facing the free ends of the rods.

The shaking mechanism plates 7 are provided with height adjusting elements.

The separating device slave. Melts as follows.

The tuber-bearing mass (Fig. 1) is cut by plowshares 1 and fed to the bar elevator 2. The mass bends the rods 4 (Fig. 4), which move along the guides 6 with the chains. The ends of the bars come in contact with the shaking mechanism. Since the plate 7 has a wave-like shape, the rods periodically bend in the opposite direction, which leads to shaking of the elevator and increasing the separation capabilities of the machine. The initial installation of the shaking mechanism 5 in height is carried out, for example, by screw mechanisms. The initial clearance between the bars and the limiters is set depending on the state of the soil.

The activation of soil separation occurs due to the complex movement of the elevator bars and the change in the direction of the forces acting by the bars on the formation. The ends of the rods move along the guides of the side walls,

representing a wavy surface. Conventionally, it is possible to select sections on the guide that determine the mode of the bar. When the position of the end of the rod at point I, the latter occupies a horizontal position (Fig. 3), at point II - concave (Fig. 4), at point III - horizontal (Fig. 5). On the subsequent wave, the operating mode is similar. Moving with

rods in the longitudinal direction, the formation is simultaneously subjected to shaking in the vertical direction, which contributes to its destruction and sifting through the inter-rod distance to the soil surface.

The separating device allows to exclude additional operations on the secondary digging of the soil, to increase the speed of the machine. The length of the separation device is chosen so as to ensure complete separation of the soil and to obtain tubers at the exit.

The tuber harvester separator can be used to

washing of root crops under the condition that it is operated in water with the installation of a loading device instead of digging shares, as well as for harvesting fodder and table root crops in a form similar to

tuber mi potatoes.
