Cotton stalk-drawing crushing harvester

Abstract

The invention provides a cotton stalk pulling and crushing harvester and relates to an agricultural machine. The cotton stalk pulling and crushing harvester of the invention comprises a conventionally-installed frame, a reel, a stalk lifter, a stalk divider and a depth wheel and also comprises a floating stalk pulling platform, a crusher, a delivery groove and an aggregate platform, wherein, the floating stalk pulling platform is arranged at a position slightly afterward below the reel and formed by the horizontal arraying of a stalk pulling hob, a conveying and cleaning wheel and a delivery roller; the depth wheel is installed at the front end of the floating stalk pulling platform while the rear end thereof is hinged and supported on the frame; the crusher is arranged behind the floating stalk pulling platform and comprises a main shaft of the crusher, a flail knife and a cover case fixed on the main shaft of the crusher, a mixing net arranged at the posterior aspect of the main shaft of the crusher and a screen positioned between the main shaft of the crusher and the mixing net; one side of the cover case of the crusher towards the floating stalk pulling platform is cut with a feeding inlet; one end of the delivery groove is connected with the mixing net while the other end thereof is erected above the aggregate platform. The cotton stalk pulling and crushing harvester of the invention has the advantages of high mechanization and productivity, low cost on the harvesting of cotton stalk and remarkable social and economic benefits.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a cotton stalk pulling and crushing harvester matched with a tractor. Background technique [0002] At present, there are generally two methods for mechanized treatment of cotton stalks in the field. The first is the mechanized cotton stalk pulling technology, which uses a cotton stalk pulling machine to carry out mechanized stalk pulling operations. The pulled cotton stalks are manually sorted, bundled and transported and then used as living fuel or centralized crushing as raw materials for industrial production. Although this method replaces the manual stalk pulling operation by mechanical stalk pulling, it has many operating procedures, high labor intensity, and low economic benefits. The second is the technology of straw crushing and returning to the field, which includes two methods. One is that the straw pulling machine at the front of the machine first pulls out the straw, and t...

AI Technical Summary

Problems solved by technology

However, although the cotton stalks are returned to the field after crushing, their rotting speed is slow, which affects the planting and growth of the next crops, and the fertilizer effect is not obvious

In particular, the stalks are directly crushed and returned to the field without pulling out the stalks. Although the part above the topsoil of the straw is crushed and returned to the field, the roots of the stalks are still buried in the soil, which creates difficulties for subsequent farmland operations.
