Foldable scraper blade type conveying arm for cutting type sugarcane harvester

Abstract

The invention discloses a foldable scraper blade type conveying arm for a cutting type sugarcane harvester. The foldable scraper blade type conveying arm for the cutting type sugarcane harvester comprises an upper arm section, a lower arm section, a folding driving portion and a chain scraper blade mechanism, wherein one end of the upper arm section is hinged to a first driven chain wheel shaft; the other end of the upper arm section is provided with a driving chain wheel shaft; one end of the lower arm section is hinged to the first driven chain wheel shaft; the other end of the lower arm section is provided with a second driven chain wheel shaft and is hinged to a horizontal angular rotating plate through a first hinge pin; the lower arm section is connected with the cutting type sugarcane harvester through a first hydraulic cylinder; the upper arm section and the lower arm section are driven through the folding driving portion and can be folded or unfolded; bottom plates for supporting materials are respectively arranged on the upper arm section and the lower arm section; two chains of the chain scraper blade mechanism are wound on chain wheels at two ends of the first driven chain wheel shaft, two ends of the second driven chain wheel shaft and two ends of the driving chain wheel shaft; and a scraper blade for scraping materials on the bottom plates is arranged between the two chains. The foldable scraper blade type conveying arm can accurately convey sugarcane sections, and can be folded in a conveying process.

Description

technical field [0001] The invention relates to the technical field of sugarcane segment conveying, in particular to a foldable scraper-type conveying arm for a section-cut sugarcane harvester. Background technique [0002] Sugarcane harvesting machinery is divided into whole-bar sugarcane harvesters and cut-section sugarcane harvesters according to whether the harvested sugarcane is cut into sections. [0003] The segmented sugarcane harvester generally needs to transfer the sugarcane segments to the field transport vehicle in time to obtain the harvested sugarcane segments. At this stage, there are two ways to deliver the cane segments to the transporter. One is to stack the harvested sugarcane segments first, and then send them into the field transport vehicle at one time. The other is to use the scraper type conveying arm to send the harvested sugarcane segments into the accompanying field transport vehicle in real time. The advantages of the mechanism of stacking fir...
