Equipment capable of spraying biogas slurry and turning over and burying straws and stratified straw returning method

Abstract

The invention relates to equipment capable of spraying biogas slurry and turning over and burying straws and a stratified straw returning method. The equipment capable of spraying biogas slurry and turning over and burying straws includes a rack, a pushing plow, a ditching plow, a ground wheel component, a hydraulic cylinder, a hanger, a connecting shaft, a biogas slurry spraying system and a power system. The hanger is connected with the front end of the rack in the advancing direction through the connecting shaft, and the rack can rotate around the connecting shaft. Biogas slurry spraying components are arranged at the upper portion of the hanger. The hydraulic cylinder is obliquely arranged on one side of the connecting shaft. One end of the hydraulic cylinder is connected with the hanger, while the other end is connected with the rack. The power system is connected with the hydraulic cylinder to transmit power and drive the hydraulic cylinder to stretch out and draw back and drive the rack to turn over 180 degrees around the connecting shaft. The ground wheel component is arranged at the left side of the rack in the advancing direction, the pushing plow and the ground wheel component are arranged at the same side of the rack, and the ditching plow is arranged at the right side of the rack in the advancing direction. The equipment achieves a turn-over function of operating plows as an upper plough share and a lower plough share work alternately. Therefore, the work efficiency is improved, the labor intensity is reduced, and the stratified straw returning purpose is achieved.

Description

technical field [0001] The present disclosure relates to the field of agricultural machinery research, in particular to a machine tool for spraying biogas slurry, turning over and burying straw, and a method for layered returning to the field. Background technique [0002] Crop straw is an important renewable natural organic matter resource. Statistics show that the total amount of various crop straws in the world is about 4.5 billion tons each year. With the improvement of people's living standards and the development of agricultural mechanization, in order to save time and labor, farmers burn the crop straws that were used as fuelwood for farmers in the harvest season, which not only wastes resources and pollutes the environment, but also harms the soil ecosystem. cause serious impact. At present, returning straw directly to the field is the most important and effective means and way to solve the problem of comprehensive utilization of straw. At present, there are three ...

Problems solved by technology

However, frequent soil tillage not only causes the soil in the plow layer to be dense, but the bottom of the plow layer is thickened and moved up, which affects the infiltration of precipitation and accelerates the consumption of soil organic matter. Moreover, because the depth of burial is the same every year, the decay time of straw is short, resulting in incomplete decomposition and affecting The full release of straw nutrients reduces soil fertility and affects the sowing and growth of crops in the next season

At the same time, due to the problems of high labor intensity, low operation quality, inability to spray biogas slurry simultaneously, and inability to operate machines in close proximity to the field due to the problems of high labor intensity and low operation quality in straw burying and returning to the field, the promotion effect of straw burying and returning to the field is greatly affected.

[0004] The invention patent with the patent number of 201410448650.2 in the prior art discloses the operation method and equipment for synchronous returning of straw and biogas slurry to the field. Although the synchronous returning of straw and biogas slurry to the field is realized, the burial depth of this method is the same every year, and the burial depth of straw cannot be changed. The straw decay time is short, resulting in incomplete decomposition, affecting the full release of straw nutrients, reducing soil fertility, and affecting the sowing and growth of crops in the next season; moreover, the machine does not have the function of adjusting the depth of straw burial and the structure of the machine is complex.
