A spring-tooth type decomposing agent spraying device for straw returning to the field

Abstract

The invention discloses a spring-tooth type decomposing agent spraying device for straw returning to the field, which belongs to the technical field of agricultural machinery. The spring-tooth type decomposing agent spraying device for straw returning to the field includes: a frame, the left end of the box body is fixedly connected with the drawbar, and the lower right end of the box body is provided with an outlet; the front and rear sides of the outlet are respectively fixedly connected to panels, For the hinged cover, the bottom of the panel is connected to the first roller; for the picking and turning system, the upper end of the connecting rod is fixedly connected to the traction rod, and the shaft of the connecting rod is connected to the rotating shaft. There are multiple spring teeth for agricultural machinery on the rotating shaft. Roller; spraying system, the medicine box is fixed on the top of the box, and the connecting pipe is connected to the medicine box. The spring-tooth type decomposing agent spraying device for straw returning to the field of the present invention adopts the method of separating wheat stubble and straw, spraying decomposing agent on wheat stubble and straw at the same time, and finally unified rotary plowing and returning to the field, avoiding the decomposing agent. It can be sprayed on the surface of the straw to cause the problem that the decomposing agent cannot be sprayed on the stubble and the lower part of the straw.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a spring tooth type decomposing agent spraying device for straw returning to the field. 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. Straw returning can increase soil organic matter, improve soil structure, loosen soil, increase porosity, reduce capacity, and promote microbial activity and root development of crops. There are two ways to return straw to the field. One is to plow and return the straw to the field. This method takes 2 to 3 years for the straw to decompose. The time is too long, which is not conducive to the absorption of nutrients by plants; In the field, more eggs will be hatched in the stalks by this method, res...

Problems solved by technology

Modern agriculture uses a harvester to harvest wheat. The harvester breaks up the straw and sprinkles it directly on the stubble. During the process of returning the straw to the field, the decomposing agent can only be sprayed on the surface of the straw. It cannot evenly spray the stubble and straw underneath, which seriously affects the straw returning. Due to the effect of the field, the newly planted crop seedlings are prone to yellow seedlings, dead seedlings, and reduced production. To solve this problem, a spring-toothed decomposing agent spraying device for straw returning to the field is designed.
