Straw smashing and stubble breaking rotary tillage all-in-one machine

Abstract

The invention discloses a straw smashing and stubble breaking rotary tillage all-in-one machine, and relates to the technical fields of straw returning machines and rotary tillage. The straw smashing and stubble breaking rotary tillage all-in-one machine comprises a machine frame, a machine case, a power transmission mechanism and a straw smashing device. The machine case is fixed onto the machine frame, the straw smashing device is arranged on the front portion inside the machine case, the straw smashing device rotates counterclockwise, a baffle is arranged behind the straw smashing device, the two ends of the baffle are fixed onto side plates of the machine case, a gap exists between the upper portion of the baffle and the machine case, a stubble breaking rotary tillage device is arranged on the rear portion of the baffle, and the machine case extends to the rear portion of the stubble breaking rotary tillage device. Straw is guided to the position behind the stubble breaking rotary tillage device under the action of the baffle and the machine case. Furthermore, the front side of the machine case is further provided with a straw combing plough. Press wheels are arranged on the rear portion of the machine case. The straw smashing and stubble breaking rotary tillage all-in-one machine has the advantages that straw smashing field returning and stubble breaking rotary tillage are completed at a time, residual straw which is not smashed does not exist under tracks, the efficiency is high, the energy consumption is low and soil moisture conservation is achieved. The development of the straw smashing and stubble breaking rotary tillage all-in-one machine is a breakthrough of agricultural machines.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and further relates to the technical field of straw returning machines and rotary tillage, especially an integrated agricultural machine with the functions of straw returning and stubble breaking rotary tillage. Background technique [0002] The "three rural" issues have always been a problem that the country attaches great importance to solving. At present, due to the obsolete agricultural machinery and farming methods, the cost of agricultural operations is still high. For example, the autumn wheat planting season only includes returning straw to the field, rotary tillage, and sowing. This requires the tractor to do a lot of ineffective work. A tractor with a weight of two or three tons walks in the suspended soil of about 30 centimeters, and its own consumption requires about 15-20 horsepower. The wheels with a width of 70 to 80 centimeters compact the suspended soil. , and the...

AI Technical Summary

Problems solved by technology

However, at present, straw crushing and tillage are carried out in two steps, and the straw returning machine and rotary cultivator stand-alone work efficiency is low.

And the straw is crushed before plowing, so the disadvantages are: on the one hand, the straw returning machine has a good crushing effect on the surface straw, but the lower part of the straw is still connected in strips, especially the remaining straw in the rut, which cannot be crushed

But in this way, the tractor consumes more and more power, and the overall cost has also increased a lot

Moreover, it will consume a lot of power to increase the rotating speed alone, which will cause greater wear and tear on the blade and various rotating parts.
