Middle box adjustable rotary tiller

Abstract

The invention discloses an adjustable rotary tillage stubble cleaner with an intermediate gear box and aims to solve the problems that the application range is single, the safety is low, the structure is complicated, the production and maintenance cost is low, and the like by adopting a rotary tillage stubble cleaner in the prior art. The adjustable rotary tillage stubble cleaner comprises a rack, the intermediate gear box, a stubble cleaning device and a rotary tillage device, wherein the intermediate gear box is assembled on the rack and is provided with an input shaft; the stubble cleaning device and the rotary tillage device are driven by an output shaft of the intermediate gear box; side reduction gearboxes are respectively arranged at both sides of the intermediate gear box and are fixed to the intermediate gear box; output shaft ends of both sides of the side reduction gearboxes are connected with input shaft ends of gearboxes of the stubble cleaning device and the rotary tillage device by a transmission shaft. The adjustable rotary tillage stubble cleaner with the intermediate gear box has the technical points that the output shaft of the intermediate gear box and the input shaft at both sides of the side reduction gearboxes are the same shaft, and are assembled in the intermediate gear box by a bearing block; bolt holes which correspond to bolt holes of side reduction gearbox flange plates are respectively formed in both sides of the intermediate gear box. The adjustable rotary tillage stubble cleaner with the intermediate gear box has the advantages that the structural design is reasonable and skillful, the application range is wide, the adjustment is convenient, joint operation is stable, safe and reliable, the maintenance cost is low, and the like.

Description

technical field [0001] The invention relates to an agricultural combined operation machine, in particular to an adjustable rotary tillage and stubble removal machine with a middle box, belonging to the technical field of agricultural machinery. Background technique [0002] There are two types of rotary tillage and stubble removers commonly used at present. One is the low-middle box rotary tiller and stubble remover, which is suitable for use with tractors whose power output shaft is low from the ground. It is used in conjunction with tractors whose axle is higher than the ground. Since the main structures of these two types of rotary tillage and stubble removal machines are directly connected by the middle box and the gear transmission boxes on both sides through the transmission shaft, so that the height of the power input shaft on the middle box and the ground cannot be adjusted, a single type of rotary tiller The stubble cleaner cannot be adapted to tractors with differ...
