Agricultural material impact test device and method

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 uses 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 dropped 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 take 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.

Description

technical field [0001] The invention relates to an impact test device and method for agricultural materials, which are mainly used in the collision process of agricultural materials and threshing components of different materials to obtain parameters such as limit speed, impact crushing sensitivity, acceleration after collision, and collision force, which are useful for threshing, processing, Provide a basis for the design of conveying and other devices. Background technique [0002] Research in recent years has shown that the crushing of agricultural materials is mainly related to the impact force, which is the result of the impact of agricultural material particles and rigid parts. There are many studies on the influence of centrifugal impact force on grain crushing, and different laboratories and researchers have established centrifugal impact test benches with different structures. The main models are centrifugal gun, impact meter and breaker. Their common principle is ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that the test material must be a group, and the impact process on the single material and the threshing element cannot be realized.

At present, there is no report on the experimental device and method that can simulate the collision process between the threshing element and the single-grain agricultural material
