Rice-wheat combined multifunctional one-piece device of harvesting, ditching, covering grass and spraying

Abstract

The invention relates to an all-in-one multifunctional machine for combined reaping, ditching, burying and spraying for rice and wheat, which comprises a ditching device, a straw guide device and a spraying device, wherein the ditching device is connected with a tail beam of a combined harvester through a movable bracket; the straw guide device is hinged with a straw discharge opening of a threshing separating device of the combined harvester through a pin shaft; the ditching device comprises a gear box, a ditching cutter head and a hydraulic oil cylinder; the ditching cutter head of the ditching device is arranged on the resistance central line of the tail of the machine through the movable bracket; and the spraying device is also arranged, and a spraying nozzle of the spraying device is positioned at an inlet of the straw guide device or the ditching surface of the ploughed ditch. The all-in-one multifunctional machine has the advantages that: the ditching cutter head of the ditching device is arranged on the resistance central line of the machine through the movable bracket, so that the machine cannot bear the push force action of sides when carrying out operation, and the machine can maintain rectilinear motion; and the spraying device sprays biological bacterial fertilizer (decay agent) on the straws at the inlet of the straw guide device or the plugged ditch surface, and can promote the straw to return to the filed and decay as soon as possible.

Description

technical field [0001] The invention relates to a multifunctional integrated machine for rice and wheat combined harvesting, ditching, burying grass and spraying, in particular to a multifunctional integrated machine that integrates harvesting, threshing, ditching and spraying biological bacterial fertilizer (decomposing agent) on the straw that has been returned to the ditch and returned to the field after harvest. Anti-corrosion all-in-one machine. Background technique [0002] Mechanized straw returning can process a large amount of crop straw in a timely manner, avoid environmental pollution and resource waste caused by improper handling of straw, and can increase soil organic matter content, fertilize soil, and increase crop yield. In order to carry out straw returning to the field, my country has developed a variety of crop straw returning machines, such as straw crushing and returning machines, reverse rotary tillage and stubble removal machines, paddy field grass bur...

Problems solved by technology

[0004] The purpose of the present invention is to: aim at the already applied patent application No. 200820042026.2, there is a problem that if the ditching cutterhead deviates from the machine resistance center line, the machine maneuverability is poor, and the straw introduced into the ditch is difficult to decompose in a timely manner. Based on the patent application No. 200820042026.2, a new rice-wheat combined harvesting, ditching, burying, grass spraying and spraying multifunctional all-in-one machine is provided
