Machine for chopping and returning rice and wheat straw root stubbles into soil

Abstract

Provided is a machine for chopping and returning rice and wheat straw root stubbles into soil. An input shaft protection sleeve and a hanging frame assembly are arranged on the top of a cardan shaft which is connected with a middle gearbox assembly. After speed of the middle gearbox assembly is changed, the middle gearbox assembly is respectively connected with a side edge gearbox assembly and a chopping belt transmission assembly through a left transverse shaft and a right transverse shaft. Side plates are mounted on two sides of a rotary tillage cutter shaft. The chopping belt transmission assembly drives a chopping cutter shaft assembly to rotate. The machine is characterized in that an upper transfer roller and a lower transfer roller are mounted between the rotary tillage cutter shaft and the chopping cutter shaft assembly, and a straw guiding plate is arranged between the upper transfer roller and the lower transfer roller. The machine has the advantages of being simple in structure and convenient to select and assemble; and a hob and a stationary knife are adopted to chop the straw root stubbles in a matching mode, a cutting mode is bearing cutting, labor is saved, and power consumption is little.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a machine for chopping and returning rice and wheat straw stubble to the field. Background technique [0002] Generally, rice and wheat stalks are mechanized and returned to the field directly, and there are two ways of returning to the field: dry field and paddy field. In the dry field, one is to use the harvesting machine to configure the straw chopping device, and at the same time of harvesting, the straw fed into the machine is chopped and then thrown to the field to complete the returning operation of the straw, but it is not possible to treat the straw left in the field after harvesting. The stubble is chopped. In addition, the use of the reverse stubble removal rotary tiller directly covers and returns the harvested straw and root stubble to the field while plowing the soil, but it does not have the effect of chopping the straw and root stubble; the general...
