Sand sieving machine for small building machine

Abstract

The invention discloses a sand sieving machine for a small building machine, and belongs to the technical field of sand sieving machines. The sand sieving machine comprises a sand sieving device and aconveying device. A screen frame is arranged on the upper portion of the sand sieving device. The conveying device is arranged on the side face of the screen frame. A metal screen is fixed to the upper portion of the screen frame. A fine san grain outlet is arranged in the middle of the sand sieving device. A machine box is arranged at the bottom of the sand sieving device. A transmission box isarranged on the outer side of the machine box. A first transmission chain is arranged in the transmission box. A second transmission chain is arranged in the conveying device. A collection conveying belt is arranged on the outer side of the second transmission chain. According to the sand sieving machine, fine sand grains passing through the screen frame are conveyed through the fine sand grain outlet arranged in the middle of the sand sieving device, finally fine sand subjected to sand sieving treatment through a C-shaped discharging opening is collected, the sand sieving efficiency is high,sand can be effectively screened and extracted, the processing cost is saved, the feeding height of the whole machine is small, the size is small, the weight is small, moving is flexible, operation isconvenient, and adaptability is high.

Description

technical field [0001] The invention relates to the technical field of sand screening machines, in particular to a sand screening machine for small construction machinery. Background technique [0002] At present, sand needs to be re-screened during construction to obtain finer sand. Generally, manual screening is used. The equipment is relatively simple and easy to carry, but usually the efficiency is very low, time-consuming and labor-intensive. The machine can effectively filter and screen building material sand and stone, so as to facilitate the extraction of sand, but there are still some deficiencies in the existing construction drum sand screen machine, which is inconvenient to pour out the larger particles in the drum. And the height of sending sand in the drum is relatively high, which is relatively laborious; other existing sand screening equipment is relatively heavy, and it is difficult to carry, which increases the heavy construction task. Therefore, how to des...
