A breeding seed material removal device for agricultural research

Abstract

The invention discloses a breeding seed impurity removal device for agricultural research. The breeding seed impurity removal device for the agricultural research comprises a device shell, a worm, a crankshaft, a sealing cylinder, a crushing roller and a screen plate. A feed hopper is fixed to one side above the outside of the device shell in a communicating mode, and a drive motor is fixed to theother side above the outside of the device shell; the worm is rotationally connected to the lower output end of the drive motor, and the upper part of the worm penetrates through the device shell andis rotationally connected with a bearing; a worm wheel meshes with one side of the worm, the worm wheel is rotationally connected with one end of a cross beam, and the crushing roller is rotationallyconnected to other end of the cross beam; and the crushing roller is eccentrically arranged on one side of the feed hopper, and the crushing roller and the worm wheel are connected through a synchronous belt. The screen plate is arranged below the crushing roller, the crankshaft is fixedly connected to the lower end of the worm, the lower part of the crankshaft is rotationally arranged in the sealing cylinder, the sealing cylinder is fixed to the bottom of the interior of the device shell, one end of a second connecting rod is combined with the middle bend of the crankshaft in a sleeving mode, the other end of the second connecting rod is rotationally connected with the back surface of a sealing plug, and the edge of the sealing plug is hermetically and slidably connected with the inner wall of the sealing cylinder.

Description

technical field [0001] The invention relates to research equipment, in particular to a breeding seed material removal device for agricultural research. Background technique [0002] In the process of agricultural research experiments, better seed materials are often selected through breeding. High yield, stable yield, high quality and high efficiency are the goals of breeding. However, the specific breeding objectives should comprehensively consider the current situation of local varieties, breeding basis, natural environment, farming system, cultivation level, economic conditions and other factors, and be adjusted continuously with the development of production. It is also necessary to use several representative varieties with large planting area in this area as the standard to clarify the directions that need to be maintained or improved, improved or overcome, so as to make the breeding goals concrete. [0003] During breeding, it is necessary to clean the seed material ...

AI Technical Summary

Problems solved by technology

[0003] During breeding, it is necessary to clean the seed material to remove impurities such as branches, leaves and dust, so as to facilitate soilless cultivation in laboratories or greenhouses. At present, most of the existing seed material removal devices use two steps to remove the seed material. Larger impurities and smaller impurities in the material, the process is cumbersome
