Novel seed lift conveyer of harvester

Abstract

The invention discloses a novel grain elevator of a harvester, which comprises that a cylinder shell is arranged on a machine body; the bottom end of the cylinder shell is provided with a bottom grain storage cavity, while the top end is provided with a top grain storage cavity; a lifting chain that can run with the driving force of a power plant, is arranged inside the cylinder shell via lifting sprockets and lowering sprockets; on the lifting chain, a plurality of grain storage buckets are successively arranged; the bottom grain storage cavity is connected with a bottom screw conveyer for transferring grains, while the top grain storage cavity is connected with a top screw conveyer. In the process of grain lifting, the invention is low in grain breaking rate, strong in lifting force, novel and antiwear in grain storage media, while the whole lifting device is convenient to maintain, of low power consumption and wide range of applicable crops.

Description

technical field [0001] The invention relates to a grain conveying device, in particular to a novel harvester grain elevator for transporting harvested rice and wheat grains on a harvester. Background technique [0002] At present, the elevators used to transport the harvested rice and wheat grains to the granary on domestic rice and wheat harvesting machines mostly use scraper-type or auger blades or a combination thereof, and the above-mentioned grain elevators are in the form of elevators. During the transportation of the grain, the grain is located in a segmented and not completely closed space in the elevator housing. And in order to ensure the smooth delivery of grains, there are gaps between the edge of the scraper in the elevator and the shell or between the blades of the auger and the shell, so when the grains are transported to the granary, they are easy to slip into the scraper and the shell The gap between the body or the blade of the auger and the shell, thereby...

Problems solved by technology

And in order to ensure the smooth delivery of grains, there are gaps between the edge of the scraper in the elevator and the shell or between the blades of the auger and the shell, so when the grains are transported to the granary, they are easy to slip into the scraper and the shell The gap between the body or the blade of the auger and the shell, thus crushing and crushing

Moreover, the scraper-type elevator chain and sprocket also have a certain crushing and damaging effect on the grain, so this has caused a relatively high breakage rate of the grain grain during the conveying stage; are also lower, while the power dissipation
