Description

The invention relates to agricultural engineering, namely to machines for harvesting cabbage.

A cabbage harvesting machine is known [1] containing a cutting apparatus with a pressing conveyor with an elastic mesh fabric woven from rubber slings with metal tips on traction chain contours with paws and rigid arc-shaped spacers.

The disadvantage of this machine is that during operation, the legs of the traction chain circuit and the metal tips of the slings are severely damaged by the heads of cabbage, which are significantly deviated from the plane of symmetry of the cutting apparatus and come into contact with them, which degrades the quality of the resulting product.

The claimed invention is aimed at solving the following problem: eliminating the possibility of damage to cabbage heads in the cutting apparatus of a cabbage harvesting machine.

The solution to the stated problem provides the following technical result: it allows to improve the quality of the product obtained during machine harvesting of cabbage.

To solve this problem, a known cabbage harvester, comprising a cutting unit with a pressure conveyor with an elastic mesh fabric woven from rubber slings with metal tips on traction chain circuits with claws and rigid arched struts, is equipped with soft rubber-fabric strips covering the outer surfaces of the traction chain circuit claws and the metal sling tips. The soft rubber-fabric strips are secured to the traction chain circuits along the perimeter, along with rigid arched struts, using bolted connections. They are also provided with openings along the inner edges, through which the ends of the rubber slings are threaded before being secured to the traction chain circuits using metal tips.

Providing the traction chain contours with soft rubber-fabric contour strips that cover the outer surface of the traction chain contour paws and the metal ends of the slings prevents them from coming into contact with the heads of cabbage in the cutting apparatus.

The fastening of rubber-fabric strips together with rigid arc-shaped spacers on the traction chain contours using bolted connections ensures their joint movement in the cutting apparatus.

The presence of openings along the inner edges of the soft rubberized fabric strips, through which the ends of the slings are passed before being secured to the chain traction contours, allows for the tight sealing of structural elements that could damage the heads of cabbage. Furthermore, the soft rubberized fabric strips, deforming along with the slings under the impact of the heads of cabbage during operation of the cabbage harvester, form surfaces inclined to the horizontal, centering the heads of cabbage in the middle of the cutting unit, distancing them from the hazardous area.

Fig. 1 shows a side view of a cabbage harvester; Fig. 2 is a local view A of the pressing conveyor; Fig. 3 is a section B-B of the pressing conveyor with soft rubber-fabric contour strips in the process of interaction with a cabbage head; Fig. 4 is a section B-B.

The cabbage harvesting machine contains a cutting device 1 (Fig. 1) with a pressing conveyor 2, with an elastic mesh fabric 3 (Fig. 2), woven from rubber slings 4 (Figs. 2 and 3) with metal tips 5 (Fig. 2), traction chain contours 6 with paws 7 and rigid arc-shaped spacers 8, soft rubber-fabric contour strips 9.

The soft rubber-fabric contour strips 9 are provided along the perimeter along the inner edges with openings 10, through which the ends of the slings 4 are passed in pairs and secured with the help of metal tips 5 on the traction chain contours 6 to the legs 7. In addition, the soft strips 9 are secured on the traction chain contours 6 together with the rigid arc-shaped spacers 8 using bolted connections 11 (Fig. 4).

The cabbage harvester works as follows.

During operation of the cabbage harvester, the cutting unit 1 is guided along the row being harvested. The heads of cabbage are fed to the cutting unit by the pressing conveyor 2. Soft rubberized fabric contour strips 9 are folded back along with the rubber straps 4, forming surfaces inclined to the horizontal, centering the heads of cabbage in the center of the cutting unit, separating them from the hazardous area and protecting them from damage from the chain traction circuit tines 7 and the metal ends 5 of the straps. Moreover, these structural elements, which pose a potential source of damage, are separated from the cabbage heads by a soft rubberized fabric layer. This protects the cabbage heads from damage in the cutting unit.

Since the traction chain contours 6 are accompanied along their entire length by soft rubber-fabric strips 9, the cabbage heads are protected from damage even after separation from the stalks in the cutting apparatus 1.

The proposed cabbage harvester allows to improve the quality of the obtained products by reducing damage.
