Pulse-type soil crushing and sieving instrument

Abstract

The invention provides a pulse-type soil crushing and sieving instrument. Air-dried soil enters a crushing tank body from a feeding port of the crushing tank body, a conical plug valve is arranged inthe crushing tank body, a cavity is connected with a high-pressure pulse-type air compressor, a piston is arranged at the bottom of the cavity, and a pipeline is connected with a large collection tank. The large collection tank can vibrate left and right, the large collection tank is internally provided a sieving net, a small collection tank outside of the large collection tank is connected to theinclination angle of the sieving net, the small collection tank is used for collecting soil powder that cannot penetrate through the sieving net, the bottom of the large collection tank is to be in aconical shape through filter cloth, an outlet is formed in the bottom of the large collection tank, the lower part of the outlet can be connected with a cloth bag, and the soil powder enters the cloth bag from the outlet. The pulse-type soil crushing and sieving instrument has the beneficial effects that grinding and sieving of the soil can be realized within a short time under a high-pressure pulse jet, so that required samples are obtained, and the whole process is closed without pollution.

Description

Technical field [0001] The invention belongs to the technical field of soil measurement, and relates to a pulse type soil crushing and screening instrument. Background technique [0002] At present, most soil crushing and screening technologies on the market use physical structure grinding and grinding. First, the structure of the instrument is more complicated and the cost is high; second, the long-term contact of the grinding device with the soil will cause structural wear, which not only affects the grinding quality, but may also affect the sample. create pollution. The pulse type soil crusher uses high-pressure pulse airflow to make the soil collide with each other and the soil and the inside of the cavity to crush the soil sample. It not only effectively reduces the abrasion of the equipment, but also has a simple structure. Summary of the invention [0003] The purpose of the present invention is to provide a pulsed soil crushing and sieving instrument. The beneficial effe...
