Abstract

The invention relates to soil drying and screening equipment, in particular to a screening machine for sampling and analyzing urban waste soil, which includes a machine body, a feeding hopper is arranged on the top of the machine body, crushing rollers are symmetrically arranged under the feeding hopper, and a cylinder is arranged on the top of the body. There is a splitter plate at the output end of the cylinder, a support plate is fixedly connected to the inner wall of the body, a spring and a straight rod are uniformly connected to the support plate, a filter plate is slidably connected to the straight rod, and a vibration exciter is fixedly installed at the middle end of the bottom of the filter plate. The right side of the plate is provided with a baffle plate and a guide plate, a hot air pipe is evenly provided under the support plate, a transmission belt is provided under the hot air pipe, and a collection hopper is provided on the left side of the transmission belt. , the present invention drives the filter plate to vibrate through the exciter to carry out a screening, and the effective materials fall to the belt, and then the electric hot air blower and the nozzle are used for secondary air selection, so that the screening effect of the device is achieved. At the same time, through the design of the collecting hopper, It makes the material fall concentratedly, which is convenient for the air selection of the nozzle.

Description

technical field [0001] The invention relates to soil drying and screening equipment, in particular to a screening machine for sampling and analyzing urban waste soil. Background technique [0002] With the acceleration of economic development and urbanization, the total amount of demolition of existing buildings and engineering construction continues to increase. With the promulgation and implementation of various laws and regulations on the protection of cultivated land and environmental protection in our country, how to deal with and discharge construction waste has become an important issue faced by construction enterprises and environmental protection departments. Construction waste is also called urban spoil. [0003] Urban spoils are classified into sandy soil, silt soil and cohesive soil according to the particle size range. Through the analysis of the physical and chemical properties of different types of spoils, a proper disposal method is put forward. [0004] T...
