Small-sized combine harvester with grain tank and adjustable grain discharging device

Abstract

The invention belongs to the field of harvesters, and particularly relates to a small-sized combine harvester with a grain tank and an adjustable grain discharging device. The small-sized combine harvester comprises a machine frame, and further comprises a grain tank assembly arranged on the upper back part of the machine frame, wherein the grain tank assembly comprises a grain tank, a vertical auger tube and a horizontal auger tube; the grain tank is fixedly arranged on the machine frame; the vertical auger tube is fixedly arranged at the upper inner part of the grain tank and has a vertical auger, and the bottom of the vertical auger tube is communicated with the bottom of the grain tank; the horizontal auger tube has a horizontal auger therein, one end of the horizontal auger tube is communicated with the vertical auger tube, and the other end of the horizontal auger tube is a grain discharging port; the horizontal auger tube is rotatably communicated with the vertical auger tube through a communicating tube; a rotating assembly for rotating the horizontal auger tube around the vertical auger tube is further arranged on the grain tank. A small-sized grain tank is mounted on a threshing part of the small-sized combine harvester, and a supported horizontal grain discharging auger (namely the horizontal auger and the horizontal auger tube) is mounted on the grain tank part; when grains need to be discharged, the harvester is driven to a place beside a ridge, the horizontal auger tube is rotated, and the grain discharging port is aligned to a grain collecting trunk or plastic cloth on the ridge for discharging the grains.

Description

technical field [0001] The invention belongs to the field of harvesters, in particular to a small combine harvester with a grain tank and an adjustable grain unloading device. Background technique [0002] At present, the grain feeding structure of small combine harvesters is common in China. The grain collected from the threshing section is transported by the auger and placed directly into the grain bag of the grain receiving table. However, small combine harvesters are usually harvested in mountainous and hilly fields. The fields are irregular, and the fields are very wet and rotten, with deep mud feet. After a bag of grain is full, the user must stop the operation. Because there is water in the fields, the grains are transported to the fields. When ploughing the edge, and then changing to an empty grain bag model, sometimes it is far away from the field, which is time-consuming and labor-intensive, affecting the efficiency of the operation.

However, small combine harvesters are usually harvested in mountainous and hilly fields. The fields are irregular, wet and rotten, and the mud feet are deep. Plowing the side, and then replace it with an empty grain bag machine, sometimes far away from the field ridge, which is time-consuming and labor-intensive, which affects the operation efficiency
