Abstract

The invention provides a grain bin seed clearing device for a combined harvester in a community, comprising a granary, a vibration excitation device, a grain conveying auger, a grain bin bottom plate and a frame, and a seed suction device and a seed clearing adjustment device are set at the same time, and the vibration excitation device The remaining seeds in the granary are cleared, and the seed suction device and the seed clearing adjustment device cooperate to remove the seeds that fall from the granary and fall into the bottom plate body of the grain transport auger and the bottom plate of the granary, and suck them out through negative pressure airflow. It is more thorough and solves the problems in the prior art that the test accuracy and reliability of the test are reduced due to the mixing of residual seeds and seeds harvested in subsequent tests due to unclean cleaning. It has important application value and broad application prospects.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, in particular to a seed cleaning device for a grain bin of a plot combine harvester. Background technique [0002] The plot test is a field comparative test of the selected crop varieties. It is an important link in the breeding of agricultural crops. This link has a long operation period, high precision requirements, and high labor intensity. The realization of the mechanization of the plot test can greatly improve the efficiency of breeding work. , to reduce the labor intensity of breeding operations and improve the accuracy of operations. Compared with field harvesting, there is a big difference in crop harvesting operations in plots: [0003] 1) The area of ​​a single community is very small; [0004] 2) Different crop varieties are planted in adjacent plots. After each plot is harvested, the seeds in the machine must be cleaned before harvesting the next plot to avoid mixing of differe...
