Blockage-prevention type feeding device of sugarcane harvesting machine

Abstract

The invention discloses a blockage-prevention type feeding device of a sugarcane harvesting machine. The blockage-prevention type feeding device comprises a machine frame, an upper feeding roller, a lower feeding roller, an end cover, a gasket, a regulating screw bolt, a regulating spring, a slide block, a slide groove and the like, wherein the slide groove, a runway-shaped installing hole and a regulating screw bolt installing hole are processed in the lower end of the machine frame; the feeding roller mainly comprises a power input shaft, a roller frame, a clamping plate, a conveying element and the like; six rib plates are welded in the circumferential direction of the roller frame; the conveying element and the clamping plate are arranged on the rib plates through screw bolts; the slide block is put in the slide groove; the middle part of the slide block is the bearing seat; the lower end of the slide block is elastically connected with the machine frame through the regulating spring; upper and lower conveying rollers are independently driven by a hydraulic motor; the conveying passage can realize the floating change along with the diameter and quantity change of the fed sugarcane; the blockage and fracture in the sugarcane feeding process can be effectively reduced; the contact area with the sugarcane stems and stalks can be increased by the conveying element; the leaf feeling operation can be performed in the conveying process. The impurity content, the fracture rate and the peel damage rate of the sugarcane after the harvesting can be effectively reduced.

Description

technical field [0001] The invention relates to agricultural machinery technology, in particular to a feeding device used in mechanized harvesting of sugarcane. Background technique [0002] The mechanized harvesting of sugarcane is time-saving and efficient, which greatly reduces the production cost and labor consumption of sugarcane farmers, so it has been paid more and more attention in the main sugarcane planting areas in my country. After more than half a century of development, my country's sugarcane mechanized harvesting technology has made significant progress, and developed medium-sized and small-sized whole-stalk and cut-off sugarcane combine harvesters with independent intellectual property rights, but the existing models are not suitable for lodging, bending and The entangled sugarcane has insufficient adaptability. After harvesting, it contains impurities, breaks and damages seriously, and it is difficult to meet the requirements of the sugar factory. Even during...

AI Technical Summary

Problems solved by technology

At present, the feeding device of the sugarcane harvester is mainly composed of a pair of rollers distributed on both sides of the conveying channel. The upper and lower rollers transmit power through gears. The distance between the conveying channels remains unchanged during operation, and the conveying elements are fixedly installed on the rollers. On the other hand, this reduces the adaptability of the conveying roller to sugarcane of different diameters and degrees of curvature, and easily leads to blockage of the conveying channel, damage or even breakage of the sugarcane skin
