Abstract

The invention discloses a novel soil grinding centrifugal type sieving device, which belongs to a civil engineering experimental instrument. The device is characterized in that a motor II at the upperpart of a loading bin drives a connecting rod IV and a grinding cone which are sequentially fixedly connected with the motor II, a turntable fixedly connected with a motor IV is arranged at the lowerpart of the loading bin and is provided with a motor V fixedly connected with a rocker arm and a plurality of discharge ports, and a discharge bin is arranged below each discharge port. The device integrates grinding and sieving, has a novel structure, is simple to operate, improves sieving efficiency, saves labor, and is safe and reliable in running and operation.

Description

technical field [0001] The invention belongs to civil engineering experiment equipment, which is an equipment integrating soil grinding and screening. Background technique [0002] In the design of civil engineering, the determination of the particle composition of the soil is a technical basic work that must be completed. General laboratory soil sample grinding needs to use a rubber-headed pestle to grind along the wall of the mortar. After grinding, pour it into a multi-layer sieve, and rely on gravity and vibration from top to bottom to obtain soil samples with different particle sizes. Sample. Traditional manual grinding and screening, on the one hand, manual operation, low work efficiency and poor data accuracy; on the other hand, soil dust suspended in the air has a great impact on the health of workers. Contents of the invention [0003] The purpose of the present invention is to provide a novel soil grinding centrifugal screening device, which improves the effici...
