Device and method for total straw returning, layered plowing, fertilizing, sowing and pressing compound operation

Abstract

The invention discloses a device and a method for total straw returning, layered plowing, fertilizing, sowing and pressing compound operation. The device comprises a first shaft-side transmission case and a second shaft-side transmission case. The first shaft-side transmission case and the second shaft-side transmission case are respectively arranged on the left side and the right side of a framework, a left side plate and a right side plate are respectively fixed to the two sides of the framework, a first rotary blade shaft and a second rotary blade shaft are arranged between the left side plate and the right side plate, and the first rotary blade shaft is positioned above the front of the second rotary blade shaft; the lowermost portion of the first shaft-side transmission case is higher than the lowermost portion of the second shaft-side transmission case; plowing areas of first-shaft rotary blades simultaneously cover plowing areas of second-shaft rotary blades and an area corresponding to the second shaft-side transmission case; fertilizing cases and sowing cases are arranged at the rear of the second rotary blade shaft, and a straw cutting device is further arranged at the fronts of the first-shaft rotary blades. The method includes steps for one-step straw cutting, rotary plowing, fertilizing, sowing and pressing compound operation. The device and the method have the advantages that total straw can be returned to fields, the plowing depth can be increased, and the plowing efficiency can be improved.

Description

technical field [0001] The invention relates to a device and method for returning straw to the field for fertilization and sowing, and belongs to the technical field of agricultural planting. Background technique [0002] my country's current annual output of straw is about 620 million tons, and only 6% of the straw is returned to the field. A large number of them are discarded and burned, 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 Plan" and "Fertile Soil Plan", and issued emergency notices many times, requiring all localities to strictly prohibit the burning of straw, and do a good job in returning straw to the field and comprehensive utilization. [0003] The current single-axis rotary tiller has a shallow plowing depth (less than 16cm), and the straw ratio in the soil is too high, which affects the...

AI Technical Summary

Problems solved by technology

However, the installation width of the rear rotary tiller shaft of the existing double-layer cutting rotary tiller is greater than or equal to the installation width of the front rotary tiller shaft, which makes it difficult for the rear rotary tiller shaft to enter the soil, not only difficult to reach the required plowing depth, but also Increase resistance during rotary tillage

In addition, the double-shaft transmission box slides against the soil in the soil, which not only increases the resistance, but also increases the wear of the transmission box body

In short, the existing double-layer cutting rotary tiller is difficult to meet the requirements of the plowing depth, the power consumption of the rotary tiller is large, and the efficiency of the rotary tiller is low, which can no longer meet the higher requirements of the market.
