Sandstone grinding and screening plant for construction engineering

Abstract

The invention discloses a sandstone grinding and screening plant for construction engineering. The sandstone grinding and screening plant comprises a raw material automatic conveyer, a filter unit and a grinding and screening plant, wherein the lower part of the raw material automatic conveyer is provided with the filter unit; the filter unit comprises a shell; the right side of the filter unit is provided with the grinding and screening plant; the grinding and screening plant comprises a housing; and a lifting conveyor belt is arranged between the shell and the housing. When the excessive raw material is accumulated in the filter unit, the blanking conveyor belt automatically stops, the baffle automatically resets to automatically block the blanking port, the driving roller on the lower side increases the vibration amplitude of the filter screen through an elastic rope so as to enhance the filter effect, the grinding and screening plant grinds the raw material and divides the raw material into three types with different particle sizes, and the raw material with different particle sizes is adopted according to the construction requirements. The sandstone grinding and screening plant has the advantages of ingenious structure and reasonable design, and is convenient for popularization.

Description

technical field [0001] The invention relates to a grinding and screening device, in particular to a sandstone grinding and screening device for construction engineering. Background technique [0002] In the process of building construction, sand and stones of different particle sizes need to be used according to different building requirements. When screening sand and stones, the construction unit usually places an inclined sieve on the ground, scoops up sand and stones with a shovel and pours them directly. On the sieve, to achieve simple screening of sand and gravel, in this case, the screening of sand and gravel is not thorough, and the work efficiency is low, and the sand and gravel cannot be ground, and the quality of construction is difficult to be guaranteed. Therefore, a sandstone grinding and screening device is needed, which can grind sandstone and sieve sandstone with different particle sizes. [0003] In the Chinese patent with the authorized notification number...

Problems solved by technology

[0002] In the process of building construction, sand and stones of different particle sizes need to be used according to different building requirements. When screening sand and stones, the construction unit usually places an inclined sieve on the ground, scoops up sand and stones with a shovel and pours them directly. On the sieve, to achieve simple screening of sand and gravel, in this case, the screening of sand and gravel is not thorough, and the work efficiency is low, and the sand and gravel cannot be ground, and the quality of construction is difficult to be guaranteed. Therefore, a sandstone grinding and screening device is needed to grind sandstone and sieve sandstone with different particle sizes

[0003] In the Chinese patent with the authorized notification number CN104624489B, a sand screening device is disclosed, which can screen sand with different particle sizes into two types of different particle sizes, but the device does not have a grinding device for sand screening. Grinding stones to allow more sand to meet the requirements of use. The device screens the sand into two types with different particle sizes, which cannot meet the construction needs, and the device does not have a blanking device to realize automatic filling of materials. Function to stop feeding
