Side edge vertical shaft type double-shaft double-layer cutting rotary cultivator

Abstract

The invention provides a side edge vertical shaft type double-shaft double-layer cutting rotary cultivator in the field of agricultural machines. The rotary cultivator comprises a machine frame, wherein am intermediate transmission case, a first side transmission case and a second side transmission case are arranged on the machine frame, a left side plate and a right side plate are fixed to the two sides of the machine frame, a left bearing base and a right bearing base are connected to the outer side of the left side plate and the outer side of the right side plate respectively, a first rotary cultivation cutter shaft and a second rotary cultivation cutter shaft are rotationally connected between the left side plate and the right side plate, the leftmost section of the first rotary cultivation cutter shaft is mounted in the left bearing base, the rightmost section of the second rotary cultivation cutter shaft is mounted in the right bearing base, a first rotary cultivation cutter set and a second rotary cultivation cutter set are fixedly installed on the first rotary cultivation cutter shaft and the second rotary cultivation cutter shaft respectively, and the first side transmission case and the second side transmission case are provided with a first vertical shaft end-milling mechanism and a second vertical shaft end-milling mechanism respectively. Through the cutting rotary cultivator, while double-shaft rotary cultivation areas can be kept consistent, it is avoided that the second side transmission case and the right bearing base move forward with soil; the device is reasonable in structure, high in cultivation efficiency and capable of realizing deep rotary cultivation.

Description

Technical field [0001] The invention relates to a rotary cultivator, in particular to a dual-shaft double-layer cutting rotary cultivator. Background technique [0002] The current annual output of straw in my country is about 620 million tons, and only 6% of the straw is returned to the field. A large number of them were abandoned and incinerated, causing environmental pollution and fire hazards, causing serious losses to the national economy. In recent years, the Ministry of Agriculture has listed straw returning to the field as the main content of the "Harvest Harvest Plan" and the "Fertile Soil Plan", and has issued multiple emergency notices requesting all localities to strictly prohibit the burning of straw and do a good job of returning straw to the field and comprehensive utilization. [0003] The current single-axis rotary cultivator has shallow ploughing depth, and the straw ratio in the soil is too high, which affects the normal growth of wheat. There are two main solu...

Problems solved by technology

[0005] Aiming at the defects in the prior art, the purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a side vertical shaft type double-shaft cutting rotary cultivator to solve the problems caused by unbalanced cultivation depth. Deep plowing has the problem of shallow plowing in some places, improving farming efficiency and avoiding the formation of deep ditches on the field due to the dragging of the transmission box
