Small-sized vibration sand screening machine

Abstract

The invention discloses a small-sized vibration sand screening machine. The small-sized vibration sand screening machine comprises a machine frame, a driving motor, a transmission device, a vibrationdevice, a first-stage screen body, a second-stage screen body, fixing bases, a feeding hopper and a sand beating device, wherein the driving motor is arranged at the bottom of the left side of the machine frame, the driving motor is connected with the right transmission device through an eccentric wheel, the vibration device comprises a transmission rod and linkage heads which are vertically arranged, the first-stage screen body and the second-stage screen body are vertically and sequentially distributed on the lower side of the machine frame, the same sides of the first-stage screen body andthe second-stage screen body are connected to one ends of the linkage heads respectively, the other ends of the linkage heads are connected to the transmission rod, the first-stage screen body and thesecond-stage screen body are fixed on the machine frame through the four fixing bases on the lower sides of the first-stage screen body and the second-stage screen body through the linkage rods, andthe feeding hopper is arranged on the top of the machine frame above the first-stage screen body. According to the sand beating device of the vibration sand screening machine and the selection of thetwo-stage screen bodies, the sand discharging rate is greatly improved, the small-sized vibration sand screening machine is small in feeding height, small in size, light in weight, flexible to move, convenient to operate and suitable for various construction sites.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a small vibrating sand screener. Background technique [0002] The finished fine sand used in general construction sites is obtained by artificial sanding by one or two workers on an inclined screen. The labor efficiency is low, the labor intensity is high, and it is easily restricted by rainy weather. The sand with high moisture content is generally difficult to be sanded. Screening increases the waste of sand. The emergence of sand screening machines has ended the history of labor-intensive sand screening. It has high sand production rate, strong screening capacity, fast screening speed, practical, convenient and labor-saving, so it can be used in large construction sites and coal yards. , grain, gun factory, casting, flower nursery, medicinal materials, construction mortar, etc. are very popular, but there is no sand screening machine specially used in small cons...

Problems solved by technology

[0002] The finished fine sand used in general construction sites is obtained by artificial sanding by one or two workers on an inclined screen. The labor efficiency is low, the labor intensity is high, and it is easily restricted by rainy weather. The sand with high moisture content is generally difficult to be sanded. Screening increases the waste of sand. The emergence of sand screening machines has ended the history of labor-intensive sand screening. It has high sand production rate, strong screening capacity, fast screening speed, practical, convenient and labor-saving, so it can be used in large construction sites and coal yards. , grain, gun factory, casting, flower nursery, medicinal materials, construction mortar, etc. are very popular, but there is no sand screening machine specially used in small construction sites. Traditional sand screening machines are generally large in size and difficult to install, operate and maintain. The cost is high, the movement is not flexible, and the traditional sand screening machine is generally designed with a drum, no matter whether the drum is inclined or horizontal, it is easy to be blocked by agglomerated sand clusters. Although there is a high degree of automation such as conveyor belts, but The cost performance is not high for construction sites such as rural civil engineering
