Trash removal device on sugarcane harvester

Abstract

The invention discloses a sundry removing device for a sugarcane harvester. The sundry removing device comprises an upper fan and a lower fan, wherein the upper fan comprise a driving box, an upper fan motor, a fan shaft and a fan installing base; the driving box comprises an outlet cavity and a circular cavity base on the lower part; the circular cavity base is connected with the outlet cavity; the driving box is arranged on the fan installing base; a fan blade mechanism is arranged on the fan shaft; the fan shaft is arranged vertically; the upper fan motor is fixed on the driving box; the upper fan motor is connected with the fan shaft; the fan installing base is provided with a cylindrical cavity, a sugarcane discharging cavity and a sugarcane charging cavity which are communicated with one another; the sugarcane discharging cavity and the sugarcane charging cavity are formed below the cylindrical sugarcane; the sugarcane discharging cavity and the sugarcane charging cavity are formed opposite to each other on left and right sides; a sealing cover plate is provided with two paths of air outlets; wind is blown upwards through one path of air outlet; the other path of air outlet is used for obliquely blowing wind to the inlet position of the upper fan. By adopting the structure, the sugarcane leaf peeling efficiency of sugarcane can be increased effectively, and the impurity content of sugarcane segments is lowered effectively.

Description

technical field [0001] The invention relates to the technical field of sugarcane harvesters, in particular to the technology of a waste removal device on a sugarcane harvester. Background technique [0002] At present, the mechanization level of sugarcane production in my country is relatively low, and sugarcane harvesting in domestic sugarcane planting areas is basically done manually, with high labor intensity, low efficiency and poor working environment. The sugarcane harvesters researched and developed in my country are mainly whole-stalk type harvesters. The whole-stalk type sugarcane harvester disclosed in Chinese patent 2004200065614 can complete the upturning, tip cutting, cutting, feeding, conveying, leaf stripping and Stacking operations. The whole stalk sugarcane harvester lays or stacks the sugarcane in the sugarcane field, and also needs to pick up the sugarcane manually or mechanically, strip the leaves or load it into the car, which requires more auxiliary lab...

Problems solved by technology

[0003] The sugarcane combine harvesters developed by my country include side-mounted harvesters, front-mounted harvesters, and integral harvesters. The main problems are that the adaptability to harvesting of sugarcane with serious lodging is not strong, and the cutting device is easy to block. , low sugarcane stripping rate, high impurity content of sugarcane after harvest, etc.

[0004] Later, the applicant researched and developed a section-cut sugarcane combine harvester, the patent number is ZL200910173230.7, which discloses part of the technology of the trash removal device, that is, the blower of the trash removal device sucks the impurities and discharges them through the trash discharge pipe , the blower at the lower outlet pipe at the output end of the conveying stripping device can blow away the remaining impurities mixed in the sugarcane section, and no further specific effective structural measures are involved to improve the sugarcane leaf stripping rate and effectively reduce the sugarcane leaf stripping rate. In actual work, these specific effective structural measures and other corresponding structures directly determine the level of the sugarcane stripping rate and the sugarcane impurity rate, and in the section-cut sugarcane combine harvester, no Improving the performance of the stripping rate of sugarcane leaves and the impurity content in sugarcane segments will directly affect the subsequent processing of sugarcane and reduce the subsequent work efficiency of sugarcane
