Description

A straw crushing and rotary tillage machine

technical field

The invention relates to an agricultural machine, in particular to an integrated agricultural machine capable of simultaneously crushing straw and land rotary tillage.

Background technique

Agricultural issues have always been the ones we are most concerned about and urgently need to be resolved. At present, after the farmer is harvested manually, a large amount of straw left behind will be burned in the field, causing environmental pollution and a decline in soil quality. Although mechanized operations have been basically popularized, on the one hand, a single mechanical operation method is more common, that is, one device performs one function, such as straw crushing and returning to the field, rotary tillage, sowing, etc., need to work in the field many times, so that the tractor takes more time. Rolling in the field for the first time makes the soil easy to harden, and consumes a lot of energy. It is a waste of material and time to replace multiple sets of machines. On the other hand, the coverage of mechanized compound operations is not very wide. Conventional implements do not substantially solve the defects of high energy consumption and waste of materials, but instead make the implements larger and more complicated, which is not conducive to the promotion of agricultural mechanization.

Patent No. 201210332826.9 discloses a straw crushing and stubble breaking rotary tiller, which includes a frame, a casing, a power transmission mechanism, a straw pulverizer, a stubble breaking rotary cultivator, and a pressing wheel; the straw crushing is driven by the power transmission mechanism. First, the straw is crushed, and then the stubble-breaking rotary tiller is driven to plow the ground, and finally the turned soil is leveled by the pressing wheel.

The patent document with the patent number of 201410095769.6 discloses a straw picking and pulverizing machine covering a compound operation machine after sowing, including a straw picking and crushing transposition, a conveying and throwing device, and a rotary tillage planting and fertilizing device; the tractor provides power for the straw picking and crushing transposition, so that The crushed straw is passed through the rotary tillage sowing and fertilizing device to cover the ground through the conveying and scattering device, and the rotary tillage sowing and fertilizing device is also working at the same time.

Though above-mentioned two kinds of technical schemes have solved the defective when farmland unitary operation to a certain extent, have reduced labor intensity and operation cost, improved work efficiency. But this kind of compound tool is still a simple combination of traditional single work tools, so it is bulky, complex in structure and consumes a lot of energy. At present, whether it is a single straw grinder and rotary tiller or a compound straw grinder and rotary tiller, the rotation of the cutter is directly driven by the rotation of the main shaft. Although the structure is simple, the function is relatively single, and it can only be used to crush straw or Land rotation is not conducive to the promotion of modern mechanized agriculture.
