Dividing and spiral-screening cart

Abstract

The invention discloses a flow-splitting screw sand trolley, which comprises a feeding device, a flow pipe, a spiral sand screening device, a drying device, a coarse sand collection and screening device, a vibration device, a heterosexual fixed support platform, a casing and universal wheels; The device of the present invention processes the sand in the feeding device in batches through the setting of three shunt pipes at the bottom of the feeding device, which has the effect of accelerating the screening rate; The movement route of the sand increases the screening effect of the sand; through the setting of the second screen at the bottom of the coarse sand collection and screening device, it has the function of re-screening; through the setting of the drying device, it has the function of drying the moisture in the sand. The function of preventing sand from sticking to the screen and causing blockage; the setting of the internal vibration device of the fixed support platform realizes the function of vibration of the upper device and prevents the blockage of the feeding device, shunt pipe and spiral sand screening device .

Description

technical field [0001] The invention relates to a construction equipment, in particular to a diverting spiral sand screen trolley. Background technique [0002] Sand screening machine is a kind of vibrating screening mechanical equipment that uses the relative movement between sand particles and the screen surface to make sand pass through the sieve holes, and divide sand into different levels according to particle size; now, sand screening on construction sites is basically done manually. Screening, that is, using a screen to manually throw coarse sand onto the screen to sort sand and stones. This method of screening increases the labor intensity of workers during screening, and the labor efficiency is very low. The construction cost is increased, and because the screen is often in contact with wet sand, it is easy for the sand to stick to the screen and cause blockage. Manual beating is required to shake off the adhered sand, which increases labor intensity to a certain ex...

[0002] Sand screening machine is a kind of vibrating screening mechanical equipment that uses the relative movement between sand particles and the screen surface to make sand pass through the sieve holes, and divide sand into different levels according to particle size; now, sand screening on construction sites is basically done manually. Screening, that is, using a screen to manually throw coarse sand onto the screen to sort sand and stones. This method of screening increases the labor intensity of workers during screening, and the labor efficiency is very low. Increased construction costs, and because the screen often contacts wet sand, it is easy for the sand to stick to the screen and cause blockage. Manual beating is required to shake off the adhered sand, which increases labor intensity to a certain extent and affects the screening effect at the same time.
