Abstract

The invention relates to separators for separating stones from soil and plant debris and can improve separation performance. This is ensured by the fact that the sorting-separating device comprising a baffle plate and longitudinally inclined drive axles with polyhedral disks forming a trough is additionally provided with movable elastic aprons. 2 ill.

Description

The invention relates to agriculture, in particular to separators for separating stones from soil and plant residues.

The purpose of the invention is to increase the productivity of the process of separating stones from soil and plant debris by increasing the speed of movement of stones along the gutter.

In figure 1. side view of a sorting and separating device of a stone harvesting machine; figure 2 - cross section aa in fig. 1.

The sorting-separating device of the stone harvesting machine consists of a frame 1 on which longitudinally inclined parallel drive axles 2 with polyhedral disks 3 are fixed. Moreover, the axes 2 with disks 3 form the side of the trough with increasing steepness. At the lower axis 2, a reflective shield 4 is installed, the lower part of which is made in the form of a comb, which is included in the gaps between the disks 3. Above the lower axles 2 of the groove (1-4 axis) movable elastic aprons 5 are mounted, parallel mounted to the crossbars 6 chains 7, which encircle the sprocket 8 of the drive shafts 9, placed on the frame 1, above the upper ends of the two lower axles 2 of the chute is installed loading tray 10. The sorting-separating device of the stone harvesting machine operates as follows.

Rocky mass from the tray 10 enters the inclined parallel axes 2 with discs 3, the surface of which forms the side of the trough with increasing steepness. When the rocky mass moves along the rotating axes 2, the stones fall into the spaces between the aprons 5 moving along the axes 2, which grab the stones at the moment of their jump, direct the path of their fall towards the unloading direction and thereby accelerate the movement of the stones along the axes 2. Simultaneously, the aprons 5 limit the flight path of soil lumps, which consequently undergo additional

impact impact from the side of the rotating disks 3, therefore, the intensity of destruction of soil lumps also increases. When the apron 5 interacts with the crop residues, the latter are pressed by the elastic (rubber) apron 5 to the rotating disks 3, thereby increasing the reliability of adhesion of the vegetation to the disks 3, which as a result, they pick up the vegetation, cut the soil out of it and transport it accelerated in the direction of rotation of the axes 2, removing the plant residues from the zone of action of the movable aprons 5. For the vegetation is transported by discs 3 along the increasing steepness of the side of the gutter and by discs 3 of the upper drive axis 2 of the gutter is dumped onto the floor surface,

Thus, the stony mass, moving along the axes 2 (along the trench), is constantly freed from the soil and soil lumps that break into disks 3, aprons 5 and the reflective shield 4, as well as from plant debris that are pressed by aprons 5 to rotating discs 3 and thereby quickly exit the aprons 5, rising along the side of the trough and then dumped from it into the field. At the same time, the cleaned stones are rolled from the rotating discs 3 of the lower axles 2 at the end of the trough into the hopper of a stone harvesting machine or into a vehicle,

Introduction to the design of a sorting-separating device made

in the form of a gutter, movable elastic aprons, parallel mounted on the traction chains along the gutter above its lower drive axes, the lower edge of each apron being made in a circular arc concentric with the circumference of the gutter profile, which can significantly increase the productivity of the process of separation of stones from soil and plant

residues. The use of such a device on a stone harvesting machine will make it possible to exclude preparatory measures carried out before the machine starts grinding the soil lumps and plant residues with heavy disc harrows and thereby reduce the mechanical effect on the soil.

The formula is isobretic and the sorting and separating device of a predominantly stone-picking machine containing a reflective shield, longitudinally inclined drive axles with polyhedral disks forming a trough, characterized in that, in order to increase the productivity of the process of separating stones from soil and plant residues, the device is additionally equipped movable elastic aprons, parallel mounted on the traction chains along the groove above its lower drive axles, while the lower edge of each apron is made along the arc of a circle concentric with the circle of the profile of the gutter.
