Straw pickup device with adjustable pickup radius

Abstract

The invention relates to a straw pickup device with an adjustable pickup radius. The straw pickup device comprises an elastic tooth assembly, and the elastic tooth assembly comprises a shaft frame, a rotating disc, at least one elastic tooth seat, elastic teeth and a driving mechanism; the shaft frame comprises a central shaft and connecting parts mounted on the central shaft, and one end of the central shaft extends to the outer side of one connecting part to form an extending part; the rotating disc is rotationally mounted on the extending part, and at least one arc-shaped guide rail groove is formed in the rotating disc; one end of the elastic tooth seat is hinged with the connecting parts on the central shaft, and a convex part which is in sliding fit with the arc-shaped guide rail groove is arranged at the other ends of the elastic tooth seats; the elastic teeth are mounted at the other ends of the elastic tooth seats; and the driving mechanism comprises a first transmission part and a second transmission part which are rotationally connected with each other, the second transmission part is fixedly connected with the extending part, and the first transmission part is mounted on the rotating disc. According to the straw pickup device with the adjustable pickup radius, the application range of the pickup device is widened, and the pickup cleaning rate and the pickup efficiency can be effectively improved.

Description

Technical field[0001]The present invention relates to the field of agricultural machinery, and in particular, there is a tonifying pickup radius straw pickup.Background technique[0002]Straw popmock is a common component applied to straw collections in the agricultural sector. It is used in agricultural machines such as straw baler, straw pickup, which can be divided into cam type pickup and non-camout according to the classification of the pickup. Pickup, and newly-free ring pickup. The purpose is to improve the purification and pickup efficiency of straw.[0003]The main food crops in the Northeast Plain are corn, implement ridges, harvesting crops, straw crude into the field, straw in the ditch, the conventional raw tooth pickup can pick up the straw of the ridge, and is subject to pickup The straw of the longitude of the teeth cannot pick up the straw.[0004]The etholate assembly of the existing pickup is picked up by high and low raw teeth to achieve straw surface and the stalk in ...

AI Technical Summary

Problems solved by technology

[0003] The main grain crop in the Northeast Great Plains is corn, and the ridge planting system is implemented. After the crops are harvested, the straw is coarsely crushed to the field. When the straw is in the furrow, the conventional spring-tooth picker can pick up the straw on the ridge surface, which is limited by the picker’s bullet. The consistency of the tooth length The straw in the furrow cannot be picked up

[0004] The spring tooth assembly of the existing picker realizes the picking up of the ridge surface and the straw in the furrow through the high and low spring teeth. When type, there is a problem of poor adaptability
