Improved straw outlet device of machine capable of crushing straw, applying fertilizer, performing sowing and covering straw

Abstract

The invention relates to an improved device of a part of a fertilizer applying and sowing machine and particularly relates to an improved straw outlet device of a machine capable of crushing straw, applying fertilizer, performing sowing and covering straw. The improved straw outlet device comprises a pipeline (7) and a cantilever (8), the pipeline (7) backward crosses the upper portion of the fertilizer applying and sowing integrated machine, the cantilever (8) backward stretches out of the left side or the right side of an outlet of the pipeline (7), a rotation shaft (9) is vertically arranged at one end of the cantilever (8), and a plurality of blades (10) which can rotate around the rotation shaft (9) are configured on the rotation shaft (9); the vertical height of the blades (10) is 1-1.8 times of the open height of the outlet of the pipeline (7); the horizontal width of the blades (10) is 1-1.5 times of the open width of the outlet of the pipeline (7); and the distance from the position where the rotation shaft (9) is located to the outlet of the pipeline (7) is 1-1.5 times of the width of the blades (10). According to the improved device, additional power is not required, the blades rotate in a high speed under the action of wind for the pipeline to send out the straw, the crushed straw is scattered and thrown, and the crushed straw evenly covers sowed fields so that foundation and conditions are provided for good quality and high yield of crops of peanuts and soybeans.

Description

technical field [0001] The invention relates to an improved device for parts of a fertilizing seeder in agricultural machinery, in particular to the pipelines of the multi-functional unit for crushing straw, clearing straw, fertilizing, sowing, and covering straw when fertilizing and sowing crops in farmland with remaining straw An improved device for a component. Background technique [0002] Increasing the multi-cropping index is an important measure to solve the shortage of arable land due to overpopulation and little land. In the Huang-Huai-Hai area of ​​my country, after winter wheat is harvested, summer crops such as peanuts, soybeans, or corn will be planted in the next stubble. However, the large amount of wheat straw remaining in the farmland has seriously affected the sowing of next crops such as summer peanuts, soybeans or corn. Farmers often secretly burn the straw and then plant the seeds. However, burning straw will cause serious air pollution, and the governm...
