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...

Problems solved by technology

However, there are also the following disadvantages: parking is required during transshipment, continuous harvesting is not possible, and the efficiency is not high; harvesting machinery in the stacking stage increases energy consumption due to the increase in weight of sugarcane segments gradually loaded on the stacker The large and center of gravity is shifted; the conveying height is limited during transshipment, and it can only be matched with smaller height field transport vehicles or other equipment is needed to transport sugarcane to large transport vehicles

However, the disadvantages of the scraper type conveying arm are that it has poor adaptability to different transport models, the throwing position is not accurate, and it is easy to throw the sugarcane segments out of the sugarcane transport vehicle; the structure of the whole machine is not compact, especially in small and medium-sized segmented In the combined harvesting machine, if the scraper conveyor is used to send the harvested sugarcane segments into the accompanying field transport vehicle in real time, in order to match the vehicle height of the field transport vehicle and maintain the distance between the harvester and the field transport vehicle, the length of the conveying arm is not too short

But at the same time, the size of the sugarcane delivery arm is too large, which will affect the transportability and easy storage of the sugarcane harvesting machinery, and cannot reflect the advantages of the flexibility of small and medium-sized sugarcane harvesting machinery
