Root crop harvester

A technology for rhizome crops and harvesters, which is applied to harvesters, digging harvesters, excavators, etc., can solve the problems of poor soil screening effect and root crops rolling back, so as to improve the screening effect and reduce the resistance. Small, the effect of improving the screening capacity

Problems solved by technology

[0002] Now, with the influence of the concept of large-scale crop planting and the expansion of crop planting area, ordinary manual labor can no longer meet the needs of modern agricultural development. It is a development trend to replace manual work with mechanization. In recent years, agricultural mechanization has also developed. It is relatively fast, and now there are harvesters for harvesting root crops on the market. Generally, a sloping conveyor belt with a low front end and a high rear end is installed. The crops roll on the conveyor belt to shake off the bonded soil, but if the conveyor belt is set short, the effect of sieving soil is not good, if the conveyor belt is long, the root crops are easy to roll back at the back of the conveyor belt

Embodiment Construction

[0022] Such as Figure 1-6 The shown rhizome crop harvester comprises a frame 1, a blade 13 and a conveyor arranged on the rear side of the blade 13, and the conveyor includes a ring-type sieve conveyor belt 4, a supporting front axle 9 supported on the front end of the conveyor belt 4 And the supporting rear shaft 5 supported on the rear end of the conveyor belt 4, the endless conveyor belt 4 includes two endless conveyor chains and connecting rods densely arranged between the two circular conveyor chains, and the two connecting rods of each connecting rod The ends are respectively connected to two endless conveyor chains, and there is a gap between adjacent connecting rods. The conveyor also includes a supporting intermediate shaft 2 that supports the middle of the conveying surface of the conveyor belt 4, and the supporting intermediate shaft 2 is higher than the supporting front shaft. 9. The two pressure sprockets 3 are located behind the supporting intermediate shaft 2. ...

Abstract

The invention discloses a root crop harvester comprising a frame, a perching knife and a conveyer arranged behind the perching knife; the conveyer comprises an annular screen type conveyer belt, a support front shaft supporting the conveyer belt front end, and a support rear shaft supporting the conveyer belt rear end; a conveying orbital transfer mechanism comprises a support middle shaft supporting the middle portion of the conveyer surface of the conveyer belt, and a pinch roller arranged in the rear side of the support middle shaft and pressing downwards on the conveyer surface of the conveyer belt. The conveying orbital transfer mechanism is arranged in middle of the conveyer belt so as to divide the conveyer surface of the conveyer belt into 3 sections; in the front section of the conveyer surface of the conveyer belt, the crops are right scooped up from the earth, and the crops hard to fall back from the conveyer belt; in the rear section of the conveyer work surface, the crops are conveyed for certain time and partial the soils are screened off, so the crop falling back resistance is reduced, yet this section is flatter than the front section or even leans to the rear lower direction, therefore, the crops are hard to roll back.

Description

technical field [0001] The invention relates to a root crop harvester. Background technique [0002] Now, with the influence of the concept of large-scale crop planting and the expansion of crop planting area, ordinary manual labor can no longer meet the needs of modern agricultural development. It is a development trend to replace manual work with mechanization. In recent years, agricultural mechanization has also developed. It is relatively fast, and now there are harvesters for harvesting root crops on the market. Generally, a sloping conveyor belt with a low front end and a high rear end is installed. The crops roll on the conveyor belt to shake off the bonded soil, but if the conveyor belt is set shorter, the effect of sieving soil is not good, and if the conveyor belt is longer, the root crops are easy to roll back at the back of the conveyor belt. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a root cro...
