Combine-harvester air inlet device

Abstract

The invention discloses a combine-harvester air inlet device and relates to the technical field of air inlet devices. The combine-harvester air inlet device comprises a connection pipe and an air filter box, wherein one end of the connection pipe communicates with one side of the air filter box, the other end of the connection pipe communicates with an air primary filter box, an air filter plate is movably connected between the two sides of the inner portion of the air primary filter box, the two sides of the bottom of the surface of the air filter plate are both provided with filter plate clamping grooves, and filter swinging rods are rotatably connected between the front and rear two sides of the inner wall of the air primary filter box through rotating shafts. According to the combine-harvester air inlet device, by means of the combination arrangements of swinging rods, reset springs and the filter swinging rods, when the air filter plate is seriously dirty, workers can replace theair filter plate rapidly and manually, and the air filter plate can be clamped through filter clamping heads at one ends of the filter swinging rods, the replacement speed of the filter plate is effectively improved, and operations of the workers are facilitated.

Description

technical field [0001] The invention relates to the technical field of air intake devices, in particular to an air intake device for a combine harvester. Background technique [0002] Grain combine harvester, abbreviated as combine harvester, is a combined machine for harvesting crops and a harvesting machine that directly obtains grain from the field. The grain combine harvester is mainly used for combined harvesting of wheat crops, and can complete cutting, threshing, separation and cleaning in one operation in the field. When it is used for segmental harvesting, install a grain picker on the harvesting platform to pick up the dried grain strips and complete threshing, separation and cleaning operations. Before the advent of combine harvesters, threshers and mechanical harvesters greatly improved agricultural productivity in the last century. This made it possible to harvest more grain with fewer workers than before. But an invention late in the last century took this e...
