Multipurpose wheat and soybean harvester

Abstract

The invention discloses a multipurpose wheat and soybean harvester which comprises a harvester body, a power system, a cab, a crawler walking mechanism, a plant pressing mechanism, a transmission mechanism, a threshing chamber, a conveying mechanism and a grain storage chamber. The plant pressing mechanism comprises a plurality of sets of rotatable rake teeth, and the two ends of the rake teeth are installed on a quick connection support through bolts. The transmission mechanism comprises a transmission wheel train, and the number of belt wheels and the connection relation of belts can be adjusted. A concave grid of a threshing cylinder in the threshing chamber can be replaced, the concave grid for soybeans comprises a plurality of round holes which are evenly distributed, and the concave grid for wheat comprises a plurality of long-strip holes which are evenly distributed. The top cover of the threshing chamber has two types, namely a flat plate shape and an arc shape. The conveying mechanism comprises an auger and a lifter, the auger is used when wheat is harvested, and the lifter is used when soybeans are harvested. The multipurpose wheat and soybean harvester is suitable for harvesting wheat and soybeans, one machine has two purposes, and the capital investment cost of a user is reduced.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a multipurpose wheat and soybean harvester. Background technique [0002] The grain combine harvester is referred to as the combine harvester. It is a combined machine for harvesting crops. It can complete the harvesting, threshing, separating stems, removing debris and other processes of cereal crops at one time, and it is a harvesting machine that directly obtains grain from the field. Before the advent of the combine harvester, threshers and mechanical harvesters greatly increased agricultural productivity in the 19th century. This made it possible to harvest more grain with fewer workers than before. But an invention in the late 1800s took this efficiency even further. Combine harvesters combine harvesting and thresher in one unit, enabling farmers to harvest and thresh in a single operation. Thereby saving manpower and material resources, greatly reducing the burden ...

Problems solved by technology

[0005] However, the particle size and structural strength of wheat and soybeans are different. At the same time, soybeans have a high breakage rate after harvesting, which is easy to thresh and splash, and the sieve plate is blocked.
