Straw crusher used for whole-feed combine harvester

Abstract

A straw crusher used for a whole-feed combine harvester belongs to the technical field of agricultural tools. The invention aims to provide a straw crusher that is capable of matching with a whole-feed combine harvester for use and has simple structure, little power consumption, good crushing effect and convenient use. The key technical points are as follows: a driven shaft and a driving shaft arerespectively fixed with a group of saw bits (10, 9) and respectively composed of three saw bits; an upper cover (1) and a lower cover (8) of an enclosure are respectively correspondingly fixed with an upper cutter tooth (12) and a lower cutter tooth (6) matched with the three saw bits on the driven shaft and the driving shaft, and the ends of the saw bits are arranged in a partially coincident way between the saw bits on the driven shaft and the saw bits on the driven shaft. Two groups of saw bits from three cutting rolls of between the saw bits and the upper cutter tooth, between the saw bits which are opposite in rotary direction and coincident on the driven shaft and the driving shaft, and between the saw bits on the driving shaft and the lower saw tooth. The straw crusher matches withthe whole-feed combine harvester domestically used at present for use.

Description

technical field [0001] The invention relates to a straw pulverizer for a full-feed combine harvester, which is matched with the current domestic full-feed combine harvester. Background technique [0002] At present, it is known that straw pulverizers are used in conjunction with tractors. After the crops are harvested, they go to the ground to work, which increases the number of times the equipment goes to the ground and causes soil compaction; High, generally about 300rpm, the power consumption is large, and the coaxial connection with the main threshing drum will destroy its balance, and the vibration will increase. When the amount of straw is large and the moisture content of the straw is high, there will be winding and blockage. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the existing combine harvesters, such as the relatively high rotating speed of the cutter shaft and the large vibration, and the phen...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the relatively high rotational speed of the cutter shaft of the blade-type straw pulverizer used in the existing combine harvester, which is relatively large and vibrates. When the moisture content of the straw is high, there will be shortcomings such as winding and clogging. To provide a straw shredder with simple structure, low power consumption, good crushing effect, and convenient use, which can be used in conjunction with the full-feed combine harvester
