Abstract
The invention discloses a device and a method for testing agricultural material impacting, which comprises a material fixing holdfast, a projecting device, an engine, and a monitoring and controlling device, wherein an impacting ball instead of a threshing component can be used to analyze collision process between quantitative threshing components and agricultural materials, a rotary plate can obtain necessary rotary speed through changing a speed adjusting engine. The impacting ball is fed in through a breathing ball delivering port and dropped on the rotary plate under gravity effect. First the impacting ball moves on the rotary plate along a guiding ring, then rolls out through a gap of guiding ring, projects out through a projecting tube after rotating along the rotary plate for a circle under poking block effect, and is attracted by a buffering curtain and drops on a base after being collided with the testing materials. The invention is mainly used to analyze parameters as ultimate speed, impacting breaking sensibility and the like when agricultural materials are collided with the threshing components which are made of different materials. Displacement, speed, acceleration and collision force can be analyzed through a high speed camera, image processing and other methods after material collision and can provide criterion for the design of threshing, processing and delivering devices.
