Soil turning and stubble burying machine

Abstract

The invention discloses a soil turning and stubble burying machine which comprises at least one shovel knife and a traction frame, wherein the shovel knife has a certain width and is horizontally arranged; the traction frame is arranged above the shovel knife; the two sides of each shovel knife are respectively fixed on the traction frame by a connecting seat; the front end of the traction frame is connected with an external traction device; a soil guide plate and a soil turning device are sequentially arranged above the inclined rear of the shovel knife; the traction frame is driven to make horizontal motion by the external traction device; the external traction device can drive the shovel knife to scoop up the soil of a plough layer and enable the scooped soil of the plough layer to be sent onto the soil turning device along the soil guide plate; the traction frame is provided with a transmission mechanism which can output power so as to drive the soil turning device to overturn, so that the soil, conveyed to the upper part of the soil turning device, of the plough layer can be overturned and covered on the scooped ground surface. The soil turning and stubble burying machine can maintain the granular structure of the soil to the utmost extent while deeply burying full amount of straw and returning the straw to field, thus being especially beneficial to promoting the development of environment-friendly agriculture; the straw burning is replaced by burying via the machine, so that the agriculture carbon emission is reduced, and the agricultural sustainable development is promoted.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a stubble turning machine. Background technique [0002] The traditional land plowing technology has a history of more than 5,000 years. Modern plowing technology and plowing plows are essentially the same as traditional plows, except that some optimizations have been made on the surface of the plow body. The principle of plowing technology is to turn the plow layer soil to one side through a curved surface after shoveling the soil to achieve plowing. During the plowing process the surface soil is moved to one side by a distance of 30-35 cm, so the plowed field produces furrows. In the paddy field rotation area, when transplanting rice seedlings in the paddy field, it is necessary to ensure that the field surface is flat, so the plowed paddy field must be leveled manually or mechanically, which is laborious and laborious. In the past 20 years, plowing has basically withdrawn from the ...

With the development of urbanization in southern Jiangsu, a large number of farmers have left the countryside to go to towns, and a large amount of rice and wheat straw has not found a reasonable way out. The government has adopted policies to guide farmers to return all straw to the field and replace the original medium-sized tractors with high-horsepower tractors. Use the rotary tillage straw returning machine to expand the plowing depth, but because the rotary tillage is to mix the s
