A straw returning device

Abstract

The invention provides a straw returning device, which includes a tractor providing power, a traction unit is fixedly installed on the tractor, the traction unit is connected with a straw pulverizer, and the bottom of the straw pulverizer is sequentially provided with a soil turning mechanism and a straw crushing mechanism from front to back. Exit and stirring leveling mechanism. When the straw is returned to the field, it is evenly mixed with the soil layer, which is more conducive to the erosion of the straw, so that the fertilizer produced after the erosion of the straw is evenly distributed, and effectively prevents the straw from being blown away by the wind after the straw is returned to the field on dry land, which will cause waste of straw and damage the environment. The problem of pollution, the setting of its internal buffer spring also effectively protects the machinery and prolongs the service life of the device.

Description

technical field [0001] The invention belongs to the technical field of straw returning machinery, and more specifically relates to a straw returning device. Background technique [0002] Straw returning to the field is a measure of fertilizing soil fertility and increasing production that is generally valued in the world today. It can increase fertilizer and increase production while eliminating the air pollution caused by straw burning. The traditional straw returning machine simply crushes the straw and leaves it in the field, but during and after the crushing process, due to the wind force, the crushed straw debris will be blown into the air by the wind, causing harm to the surrounding residents. It causes inconvenience, and the debris of the straw is too small, and it is easy to enter the eyes or be inhaled into the human body, which is harmful to health, and the workers and farmers who operate it are also more likely to be harmed.
