Problems solved by technology

Most of them have some disadvantages: First, in most cases, the soil sample grinder is made of metal, which will affect the metal content in the soil sample during the processing process, resulting in deviations in the results
However, the existing pretreatment tools for soil sample preparation, such as wooden hammers and wooden rollers, consume a lot of manpower, but they can only simply crush the soil samples, and the treatment effect is not good.
Most other electric grinding machines for advanced processing are limited by the power supply. The pre-treatment of soil samples is complicated, and the soil samples cannot be graded multiple times. In addition, metal pollution is easy to occur during the grinding process, especially for hard soil samples, which leads to deviations in experimental results. , In addition, the existing electric grinder can only process the soil sample to a particle size range, but the invention can accurately divide the sample through the known mesh size sieve to obtain the required particle size soil sample

Abstract

The invention discloses a multi-stage adjustable soil sample grinder, wherein a sample feeding box, a funnel, a sample separating sieve and a sample filling box are fixed on a frame respectively; rails are embedded on upper and lower ends of left and right walls of the sample feeding box; adjusting bolts are arranged on front and back walls of the sample feeding box; abrasion patterns are arranged on inner surfaces of the front and back walls of the sample feeding box; a spiral cutter is arranged above a grinding shaft; the spiral cutter and the grinding shaft penetrate through the left wall and the right wall of the sample feeding box respectively; a gear assembly is fixed on the right end of the sample feeding box; the spiral cutter and the grinding shaft are respectively connected to the gear assembly; a first rotation handle is connected to a gear; a second rotation handle is connected to a grinding core; the grinding core is matched with the funnel; the grinding core is arranged in the funnel; an outlet of the sample feeding box is connected to the funnel; the sample separating sieve is located under the funnel; the sample filling box is located under the sample separating sieve. Through the multi-stage adjustable soil sample grinder, the influence on the soil sample, especially for a heavy metal detection experiment, is avoided; the multi-stage adjustable soil sample grinder is easy to assemble and disassemble and convenient to carry to the field for processing the soil sample with high degree of weathering, so that the later laboratory weathering period can be shortened.

Description

technical field [0001] The invention relates to a soil sample grinding device, in particular to a multi-stage adjustable soil sample grinding machine. Background technique [0002] Grinding of soil samples is an important step in soil and sediment testing and heavy metal analysis, and the processing results directly affect the accuracy and reliability of the experimental results. "Technical Specifications for Soil Environment Monitoring" (HJ / T166-2004) requires wooden hammers, wooden rollers, wooden sticks, plexiglass sticks, plexiglass plates, hard wood plates, and colorless polyethylene for the preparation tools of coarse crushing of soil samples. Film; Nylon sieve for sieving, the specification is 2-100 mesh. At present, the research on soil sample processing methods in our country is still in its infancy, basically relying on tools such as wooden hammers, wooden rollers or electric jaw grinders. Most of them have some disadvantages: First, in most cases, the soil sampl...
