Embodiment Construction
[0006] The present invention will be described in detail below in combination with specific embodiments.
[0007] Pulse type soil crushing and screening instrument of the present invention such as figure 1 As shown, including the broken tank body 1, the air-dried soil enters from the feed port 2 of the broken tank body 1, and the mouth of the broken tank body 1 is provided with a first-stage extrusion crushing roller 3, and the distance between the rollers is 5mm, so that the soil that cannot be The crushed larger stones and other hard substances are discharged from the crushing tank 1, and the secondary crushing roller 4 is installed under the first-stage crushing roller 3, and the distance between the rollers is 1mm, so as to remove the small stones and other materials that cannot be crushed in the soil. The hard material is discharged from the broken tank body 1. There is a conical sealing valve 5 under the secondary extrusion crushing roller 4, the conical sealing valve 5...

The invention discloses a pulse type soil crushing and screening instrument for primary crushing by using a two-stage pair of rollers. The pulse type soil crushing and screening instrument is characterized in that air-dried soil is fed from a feeding port of a crushing tank body; the opening part of the crushing tank body is provided with a first-stage extrusion crushing roller and a second-stageextrusion crushing roller, wherein a conical blocking valve is arranged below the secondary-stage extrusion crushing roller; a cavity body of the crushing tank body is connected with an external piston type air compressor, wherein the bottom of the cavity body is provided with a piston; a pipeline is connected with a large collection tank, wherein the large collection tank is provided with a screen, the inclination angle of the screen is connected with a small collection tank outside the large collection tank, and the small collection tank is used for collecting soil powder which fails to passthrough the screen; and the bottom of the large collection tank is formed by filter cloth to form a conical shape, wherein an outlet is formed, and the soil powder enters a cloth bag from the outlet.The pulse type soil crushing and screening instrument for primary crushing by using the two-stage pair of rollers has the beneficial effects that grinding and screening of the soil can be achieved ina short time through the two-stage extrusion crushing rollers and high-pressure pulse airflow, a required sample is further obtained, and the whole process is closed and free of pollution.
Description
technical field [0001] The invention belongs to the technical field of soil measurement, and relates to a pulse type soil crushing and sifting instrument for primary crushing of rollers with two stages. Background technique [0002] At present, most of the soil crushing and screening technologies on the market use physical structure grinding and crushing. First, the structure of the instrument is relatively complicated and the cost is high; create pollution. Contents of the invention [0003] The object of the present invention is to provide a kind of pulse type soil crushing and sifting instrument that carries out primary crushing to roller with two stages, the beneficial effect of the present invention is that crushing roller and high-pressure pulse airflow can be crushed in a very short time by two stages Realize the grinding and screening of soil, so as to obtain the required samples, and the whole process is closed and pollution-free. [0004] The technical scheme a...
