Reciprocating sugarcane cutter

Abstract

The present invention belongs to the technical field of agricultural machinery and particularly relates to a reciprocating sugarcane cutter. The reciprocating sugarcane cutter comprises a box body (1), a transmission device (2), reciprocating cutting devices (3) and clamping and conveying devices (4); the transmission device (2) comprises a hydraulic motor (16), a driving gear (17), a small bearing seat (18), a large bearing seat (19), a right driven gear (20), an intermediate gear (21), a left driven gear (22), a right driven shaft (23), a left driven shaft (24), a right driving sprocket (25), a left driving sprocket (26), a right cam (27) and a left cam (6); the reciprocating cutting devices (3) comprise a left reciprocating cutting device and a right reciprocating cutting device with the same structure; and the clamping and conveying devices (4) comprise a left clamping and conveying device and a right clamping and conveying device with the same structure. The cutting method requires a low cutting speed, can reduce cutting power consumption, at the same time reduces a perennial root breaking rate and improves cutting efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a reciprocating sugarcane cutter. Background technique [0002] my country is the world's largest sugarcane producer and the second largest sugar consumer in the world. Therefore, sugarcane is an important economic crop. Although the No. 1 central document "emphasizes the development of sugar production", the mechanization of sugarcane has always been a bottleneck that is difficult to break through in the process of sugar production in my country. In the whole mechanization process of sugarcane production, the most important link is harvesting. At present, the sugarcane harvesting in my country is still mainly done manually. The main reason is that the perennial root breakage rate (root stubble splitting, Cutting quality problems such as tearing) and serious problems such as uprooting will reduce the yield of sugarcane in the coming year and increase the number of ...

AI Technical Summary

Problems solved by technology

At present, most of the sugarcane harvesters at home and abroad use the traditional single-disc sugarcane cutter. Although scientific researchers have done a lot of theoretical research and experimental research on it, and continuously optimized its structure and motion parameters, in actual work There are still problems such as high rate of cutting sugarcane head breakage, large cutting loss, and serious uprooting phenomenon.

The main reason is that the single disc cutter is based on the theory of unsupported cutting, mainly relying on the inertia of the sugarcane to cut the sugarcane. During the cutting process, the sugarcane is prone to bending and stretching deformation, which causes the root stubble to split and tear.

At present, the representative models of sugarcane harvesters are mainly the A4000 produced by Case New Holland, the CH530 produced by John Deere, and the 4GQ-130 sugarcane harvester produced by Luoyang Chenhan Agricultural Equipment Technology Co., Ltd. Single-disc cutters did not solve the problems of head breaking rate and serious root uprooting well.
