Sample crushing and screening device for soil detection

Abstract

A sample grinding and screening device for soil detection, disclosed in the invention, comprises: a screening box, a screening chamber is arranged in the screening box, the inner top of the screening chamber communicates with the outside through a feeding port, a feeding hopper matched with the feeding port is installed at the upper end of the screening box, the inner bottom of the screening chamber communicates with the outside through a discharging port, and a screening net is horizontally arranged in the screening chamber; and a transmission mechanism comprising a supporting plate fixedly connected with one side of the screening box, wherein a motor is installed at the upper end of the supporting plate. When the equipment is used for screening the soil, the screening net can shake up and down, the space above the screening net in the screening chamber can be heated, and the two stirring rods are matched to rotate, so that the soil adhered to stones is easier to fall off, and the screening effect is better.

Description

Technical field [0001] The present invention relates to the field of soil detection, and more particularly to a sample milling screen for soil detection. Background technique [0002] Soil testing refers to the determination of environmental quality and changes in the determination of the representative value of the soil environmental quality factors. When the soil detection is carried out, the collected soil sample is first needed, and the block soil is broken. Then screened the soil after crushing, sieving the stone contained in the soil and some fine metal to avoid affecting the test results; [0003] The traditional screening method is generally multi-screened by several screening networks, but this screening mode is often fixed, so that the effect of screening is poor, and the soil itself contains moisture, so it will adhere On the stone, the soil with moisture is easy to block the screening network, affecting the filtering property of the screening network, the soil will st...

Problems solved by technology

[0003] The traditional screening method generally uses several screening nets for multiple screenings, but in this screening mode, the screening nets are often fixed, which makes the screening effect poor, and the soil itself contains moisture, so it will stick On stones, the soil with moisture at the same time is easy to block the screen and affect the filterability of the screen. After the soil is crushed, it will still adhere to the stone. The traditional screening method cannot handle the soil adhered to the stone. , after the screening is completed, there will still be a large amount of soil and stones staying on the screen together, and the soil cannot be screened well, so we need to design a sample crushing and screening device for soil testing to solve the above problems
