Soil sample processing equipment with function of pulverization particle size adjustment

Abstract

Soil sample processing equipment with a function of pulverization particle size adjustment comprises a shell. The top of the shell is provided with a feeding port, a pair of crushing rollers are arranged in the shell below the feeding port, a crushing rolling shaft is arranged at the center of each crushing roller in a supporting manner, a plurality of crushing teeth are uniformly distributed on the periphery of each crushing roller, and an interception screen is arranged under the crushing rollers. Compared with the prior art, the soil sample processing equipment has advantages that a secondmotor drives a second rotating shaft to rotate, the second rotating shaft drives a driving bevel gear to rotate, the driving bevel gear drives a driven bevel gear to rotate, the driven bevel gear drives a screw rod to rotate, then an adjustment rod matched with the screw rod moves downwards, and accordingly a distance between an upper pulverization plate and a lower pulverization plate is reduced,and soil pulverization particle size is changed; meanwhile, a first motor is started and drives a first rotating shaft to rotate, the first rotating shaft drives the upper pulverization plate to rotate, and pulverization projections pulverize soil; owing to vibrating devices, excellent vibrating effects of a vibrating plate are achieved.

Description

Technical field [0001] The invention relates to the technical field of soil detection, in particular to a soil sample processing device with the function of adjusting the crushing particle size. Background technique [0002] The composition of soil is very complex. Generally speaking, it is composed of three phases of solid, liquid, and gas such as minerals, organic matter produced by the decomposition of animal and plant residues, moisture and air. Soil environmental monitoring refers to the determination of environmental quality (or pollution degree) and its changing trend through the determination of representative values ​​of factors affecting soil environmental quality. What we usually call soil monitoring refers to soil environmental monitoring, which generally includes technical content such as spot sampling, sample preparation, analysis methods, result characterization, data statistics, and quality evaluation. General soil monitoring can be divided into national regional...

Problems solved by technology

[0003] When testing soil samples, it is necessary to crush the soil samples to volatilize the gas in the soil samples before testing. In the prior art, there is no suitable device to process the soil samples.
