Description

The invention relates to the field of agricultural engineering, in particular to the separation conveyors. The purpose of the invention is to improve the technical reliability and quality of the process by ensuring a smooth progress of the conveyor and application of alternating loads to the working branch without the repulsive effect of the working branch on

separated product. The separating conveyor of the harvesting machine contains an infinite bar of cloth 1, the bypass rollers in the form of elements 4 are installed at the top and bottom of the working branch. To ensure optics. The mechanism of group movement of elements 4 serves as the maximum separating ability. For the tension of the blade 1 there is a mechanism 8. Soil layers undergo a rupture of the upper layers and compression of the lower layers on the ridges. At the wave troughs, the upper layers are compressed and the lower layers are broken. On the moving and escaping areas the gap is carried out, which ensures the separation of the soil. Gz.p. f — ly, 4 ill.

The invention relates to the field of agricultural engineering, in particular to the separation conveyors used in stone harvesting machines, as well as machines for harvesting of root and tuber crops.

The purpose of the invention is to improve the technical reliability and quality of the process by means of

ensure smooth conveyor movement and application of alternating loads to the working branch without the repulsive effect of the working branch on the separating product, as well as reducing soil load on the conveyor while improving soil crumbling by gradually increasing the speed of the formation movement relative to the frame. 20

Figure 1 shows the separating conveyor, a general view; Figure 2 is the same, with elements that provide the ability to move additional guide elements in a vertical tracing plane; in fig. 3 is a diagram of one of the possible locations of additional guide elements; figure 4 is a diagram of the advancement of the soil layer along the rod bar. ^thirty

The separating conveyor of the harvesting machine contains an infinite bar of cloth 1 interconnected with the slave 2 and leading 3 stars attached to the frame, bypass rollers in the form of 35 additional elements 4 installed alternately above and below the working branch of the bar blade 1. Additional guide elements 4 can be made For example, in 40

asterisk. These elements are fixed on the sides of the conveyor frame.

To obtain the optimal separation capacity, a 5-group movement mechanism of an additional 45 guide elements 4 installed above the working branch of the bar blade serves in a vertical plane associated with the thrust 6, on which the thrust 7 is strengthened. The thrust 7 can be strengthened 50 on the thrust 6 its (not shown), thrust 6 can be made with the possibility of changing their length, for example telescopic (not shown). This ensures the individual movement of each additional element 4 installed above the working branch of the bar blade 1. In a similar way,

to move additional driving elements 4, installed under the working branch of the bar blade 1 (this variant is not shown). At the same time, in the process of work, spontaneous displacement of the loads should be excluded.

For the tension of the endless bar of the blade 1 is used, the mechanism 8 of the tension of the canvas, which can be associated with the leading 3 or driven by 2 asterisks.

To reduce soil loading on the conveyor, the guide elements 4 are installed with increasing distance from one another, where the distances a, c, b are chosen from the relation a <b <c.

The steepness of the oncoming sections of the bar blade should be such as to prevent large inclusions of the product being rolled off.

Separating conveyor harvester works as follows.

Soil strata undergo a tearing of the upper layers and compression of the lower layers on the crests of the wave along the conveyor, and the compression of the upper layers and the lower layers break at the wave troughs. On the incident and. the escaping areas are ruptured, which ensures the separation of the soil.
