Abstract

The invention relates to laboratory soil sample crushing and graded screening equipment. The laboratory soil sample crushing and graded screening equipment is characterized by comprising a lifting handle, a host, a motor, a control circuit, a power supply socket, a cutter shaft, a blade, a cup body, a cup body handle, a screen, a fastener and a material receiving box. The basic structures are combined to form soil sample screening integrated equipment; during working, the crushing and screening works of a laboratory soil sample can be realized by adding the soil sample, connecting a power supply, setting parameters and turning on a switch to begin to work; and therefore, the soil sample is conveniently pre-treated. All closed crushing and screening environments of the equipment can reduceflying of soil particles and reduce the harm of the soil sample to a human body; moreover, the operation and the use of the equipment are more conveniently carried out through reasonable circuit design; parameters of a key control module can also be set according to different requirements; a rotation time and a rotation speed of the motor are controlled to meet sample treatment demands.

Description

technical field [0001] The invention relates to the field of environmental engineering soil detection, in particular to a laboratory soil sample crushing, grading and screening equipment. Background technique [0002] At present, the problem of soil environmental pollution has gradually attracted people's attention, and at the same time, the research on soil pollution control is also developing steadily and gradually. When conducting soil pollution control research, it is necessary to test and analyze the physical and chemical properties of the soil. The requirements for soil particle size are different for different test and analysis contents. At the same time, some studies have shown that different particle sizes of soil samples have different impact on the analysis results of physical and chemical properties. The accuracy and precision have a certain influence, so it is necessary to screen the soil particle size for different experimental projects. For example, soil samp...
