Pretreatment device for soil detection

The utility model relates to the technical field of soil detection, in particular to a pretreatment device for soil detection, which comprises a dewatering box, a collecting hopper is arranged at the bottom of the dewatering box, a conveying pipe is arranged at the bottom of the collecting hopper, and a screening box is arranged at the bottom of the conveying pipe. According to the pretreatment device for soil detection, soil is subjected to pre-dehydration treatment and crushing through the dehydration box and the screening box, discharging is performed through the bottom sample discharging hopper, detection and sampling are facilitated for operators, and the problems that existing soil detection is lack of soil dehydration equipment, soil viscosity is high, moisture is large, detection is troublesome, and the detection efficiency is high are solved. According to traditional soil detection, fine soil is mostly detected, but most soil is difficult to detect due to the fact that a large number of hard cakes ar
