Anti-blockage device of full-feed combined harvester

Abstract

The invention discloses an anti-blockage device of a full-feed combined harvester. The anti-blockage device of the full-feed combined harvester consists of a machine frame, a transmission shaft, a conveyer shaft and a gear box, wherein the corresponding ends of two sections of transmission shaft are in cup joint with a first bevel gear and a third bevel gear in the gear box respectively; both the first bevel gear and the third bevel gear are meshed with a second bevel gear in the gear box; the opposite other ends of the two sections of transmission shaft are in cup joint with a first belt wheel and a third belt wheel respectively; the first belt wheel and the third belt wheel are connected with a fourth belt wheel and a sixth belt wheel through a first belt and a third belt respectively; the fourth belt wheel and the sixth belt wheel are fixedly connected with two ends of the conveyor shaft fixed below the machine frame; a control shaft controlled by a handle is arranged on the machine frame; two ends of the control shaft are fixedly connected with a shaft plate respectively; the other ends of the two shaft plate face opposite to each other; a wheel shaft is fixedly connected with the outer side of each shaft plate; a forward rotation tension wheel and a backward rotation tension wheel are assembled on the wheel shafts respectively and placed on the inner side of the third belt for connecting the third belt wheel and the sixth belt wheel and on the inner side of the first belt for connecting the first belt wheel and the fourth belt wheel; and the lower end of the handle passes through a control plate with an open groove and a through hole formed on the wheel shaft of the backward rotation tension wheel and then is fixedly connected to the control shaft.

Description

technical field [0001] The invention relates to an anti-blocking device for a full-feed combine harvester, which belongs to the technical field of agricultural machinery and equipment. Background technique [0002] When the full-feed combine harvester is harvesting, due to the large amount of feed, the load on the inclined conveyor is often too large or even blocked, which further affects the load of the subsequent threshing and cleaning process of the harvester. In order to prevent the clogging of the roller, the main method is to increase the gap between the roller and the concave plate, and adjust the tightness of the transmission belt. The traditional method to deal with the clogging is to close the transmission system, stop the transmission of the chain conveyor belt in the inclined conveyor, open the cover of the inclined conveyor, and Put the concave plate to the lowest position, pull the roller belt, and clean the blocked material by hand. This method must be shut d...

Problems solved by technology

This method must stop the machine and get off the machine for cleaning, which delays working hours and is labor-intensive, which reduces the harvesting efficiency. If the operation is not careful, it will also cause harm to the human body.
