Cereal bionic rubbing threshing test bed

Abstract

The invention discloses a cereal bionic rubbing threshing test bed. The cereal bionic rubbing threshing test bed is composed of an upper threshing device, a lower threshing device, a tracking observing device, an instrument device and a rack. The test bed can test three threshing modes including moving rubbing, rotating rubbing and combined rubbing through the rotation of an upper threshing platform and the reciprocating movement of a lower threshing platform. By means of the mounting and dismounting of an upper threshing roller, two working planes of indirect coupling rubbing and direct coupling rubbing are formed through an upper threshing bionic sample piece and a lower threshing bionic sample piece. The height of the upper threshing platform is adjusted by adjusting bolts, a high-speed vidicon is used for shooting the cereal threshing microprocess, a tension sensor is used for detecting horizontal rubbing force, a variable-frequency speed controller is used for changing the revolving speed of an upper threshing motor and the revolving speed of a lower threshing motor, and stepless speed regulating and speed displaying of the rubbing movement are achieved. The lower threshing device moves through a crank and rocker mechanism, and the movement of the lower threshing device is high in bionic approximation degree of the manual wheat rubbing behavior. The cereal bionic rubbing threshing test bed is high in rubbing threshing test micro-testing capability, complete in testing index, good in universality and simple in structure, and the test sample pieces are installed conveniently.

Description

technical field [0001] The invention relates to a grain threshing test device, in particular to a grain bionic rubbing threshing test bench, which belongs to the field of agricultural machinery. Background technique [0002] There are many kinds of grains in the field of agriculture, and the planting area is large. Grains such as wheat, rice, soybeans, and sorghum are widely used in the field of social production. At present, all kinds of grain harvesting have been mechanized. From the perspective of harvesting equipment technology, wheat and rice harvesting machinery are relatively mature, and other grain harvesting machinery is developed on the basis of the two. However, judging from the actual effect of grain harvesting, problems such as power consumption of grain harvesters, grain loss, and grain damage are still relatively serious. For the relevant test equipment of the grain harvester, from the perspective of use, it mainly focuses on the harvesting effect test such a...

AI Technical Summary

Problems solved by technology

[0003] 1. The motion mechanism of bionic rubbing and threshing is complex in design and high in cost;

[0004] 2. The test methods for the microscopic process of bionic rubbing and threshing are not perfect, and it is impossible to accurately test the microscopic process of rubbing and threshing, the movement mode and speed of rubbing and threshing, and the mechanical properties of rubbing and threshing.
