Elastic tooth type decomposition agent spraying device for straw returning

Abstract

The invention discloses an elastic tooth type decomposition agent spraying device for straw returning, and belongs to the technical field of agricultural machinery. The elastic tooth type decomposition agent spraying device for straw returning comprises a rack, a picking and plowing system and a spraying system, the left end of a box body is fixedly connected with a traction rod, and an outlet is formed in the lower right end of the box body. The front and back surfaces of the outlet are fixedly connected with panels separately, the panels are hinged to a cover plate, and the bottoms of the panels are connected with first rollers. The upper end of a connecting rod is fixedly connected with the traction rod, the connecting rod is in shaft connection with a rotating shaft, the rotating shaft is provided with a plurality of agricultural machinery elastic teeth, and the lower end of the connecting rod is connected with the first rollers. A pesticide box is fixed to the top of the box body and communicates with a connecting pipe. According to the elastic tooth type decomposition agent spraying device for straw returning, wheat stubbles and straw are separated, a decomposition agent is sprayed to the wheat stubbles and the straw at the same time, finally, unified rotary tillage returning is conducted, and the problem that the decomposition agent can only be sprayed to the surfaces of the straw, and consequently the decomposition agent cannot be sprayed to the lower portions of the wheat stubbles and the straw is solved.

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.
