A soil block crushing and screening device

Abstract

The invention relates to the technical field of crushing and screening, in particular to a crushing and screening device for soil clods, including a transport device, a primary crushing device, a screening and crushing device I, a screening and crushing device II, and a collecting device; The crushing device screens and crushes the soil clods that have been crushed for the first time in two steps. The cylinder sieve composed of blades is used to crush and screen the soil clods first, so that the soil clods are further refined, and all the soil clods are broken into medium particle sizes. The soil particles are sieved out from the cylinder, and are further crushed and refined by the crushing ball in the screening and crushing device II. grain.

Description

technical field [0001] The invention relates to the technical field of crushing and screening, in particular to a crushing and screening device for soil clods. Background technique [0002] In order to obtain the soil particles with the required precision, the existing soil clod screening device needs to be screened on the sieve and transport the soil clods that cannot pass through the screen from the screen to the crushing device for crushing and screening. The structure is complex and the process is cumbersome. In the prior art, there is also a device for crushing directly through the crushing device, but the crushing device cannot guarantee that the soil clods will be completely crushed to the required accuracy at one time, and the collected crushed soil clods cannot be guaranteed to be fine particles. All the crushing devices installed on the screen need to use driving devices, such as hitting hammers, hitting rods and other devices. All the materials on the screen are ...
