Abstract

The invention discloses an automatic belt tensioning device for a combine-harvester and belongs to the technical field of agricultural machinery, and solves the problem that a belt of the combine-harvester is prone to loosen and fall off. The technical key point of the automatic belt tensioning device is as follows: the automatic belt tensioning device comprises a cutting belt wheel, a conveyor belt, a transmission belt wheel, a driving belt and a driving belt wheel. The cutting belt wheel is connected to the transmission belt wheel, the transmission belt wheel is connected to the driving beltwheel through the driving belt, and a tensioning belt wheel is mounted on the driving belt; a tensioning mechanism composed of the tensioning belt wheel, a tensioning arm of force and pressuring wheels is mounted on the belt, is matched with the tensioning belt wheel by means of relative movement of the two pressing wheels, and the conveyor belt is tensioned in a n-shape, so that the conveyor belt is tensioned between the cutting belt wheel and the transmission belt wheel favorably, and the automatic belt tensioning device is convenient and rapid to operate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic belt tensioning device for a combine harvester. Background technique [0002] At present, the combine harvesters on the market are mainly divided into two types: half-feeding type and full-feeding type. Both full-feeding and half-feeding have their own advantages. The feeding combine harvester adopts the mode of reel and cutter to realize the cutting of stalk plants. Due to the difference in the structure of the header, it is directly related to the operation effect ratio. For example, the cleanliness of threshing, the impact on the quality of rice, and the utilization of straw and other issues. [0003] Traditional full-feed combine harvesters basically adopt horizontally arranged axial-flow drum threshing and separation devices. This arrangement has a compact structure and good operating performance when the amount of feed is small. But when using,...
