Manufacturing method of automatic and efficient multi-stage sand sieving machine

Abstract

The invention discloses a manufacturing method of an automatic and efficient multi-stage sand sieving machine. The automatic and efficient multi-stage sand sieving machine comprises a barrel, a material distribution base and an air cylinder, wherein a material distribution board is arranged inside the barrel; a filtering net is arranged inside an air outlet pipe at the top end of the barrel; the material distribution base is provided with a plurality of discharging outlets; a connection board on the inner wall of the barrel is connected with the air cylinder through a connection rod; a first sand discharge barrel, a second sand discharge barrel, a third sand discharge barrel and a fourth sand discharge barrel are sequentially arranged at the bottom end of the barrel from inside to outside and are connected with a first mesh screen, a second mesh screen, a third mesh screen and a sliding board through hinges correspondingly; the first mesh screen, the second mesh screen, the third mesh screen and the sliding board are fixed to the connection board; a plurality of vibration boards are arranged on the connection board; and an air blowing pipe at the lower end of the material distribution base is connected with air nozzles and an air inlet pipe. The automatic and efficient multi-stage sand sieving machine can automatically carry out multi-stage sieving on mixed sand, is high in sieving efficiency and free of pollution, and effectively improves the working environment of the automatic and efficient multi-stage sand sieving machine.

Description

technical field [0001] The invention relates to the field of building construction equipment, in particular to a manufacturing method of an automatic high-efficiency multi-stage sand screening machine. Background technique [0002] Sub-projects such as masonry, plastering and inlaying use a large amount of sand, and at the same time have strict requirements on the quality and particle size of the sand. Existing sand screening machines are generally open-type vibrating screens. Due to the relatively concentrated loading of materials during the work process, the discharge speed of large-grained gravel is too fast, resulting in poor use of the device and low work efficiency; Blocking the sieve holes makes it impossible to screen, and the screening effect of the device is weakened; and in the screening process, the dust is very large, so the open vibrating screen will cause pollution and affect the health of the operators. Contents of the invention [0003] The object of the ...
