Sand washing machine with automatic feeding function

Abstract

The invention discloses a sand washing machine with an automatic feeding function. The sand washing machine with the automatic feeding function comprises a sand washing tank. The two sides of the sandwashing tank are connected with moving platforms, a plurality of sliding guide rails which are arranged in parallel are arranged on the side walls of the moving platforms, and guide rail sliding strips which are matched with the sliding guide rails are arranged on the side wall of the sand washing tank. A fixed support is arranged on the outer side of the sand washing tank, a movable support is arranged on the fixed support, and an electric-hydraulic push rod which is connected with the movable support is arranged on the fixed support. A sand entering plate is connected with the sand enteringend of the sand washing tank and connected with a feeding device. The feeding device comprises an outer barrel. An inner barrel is arranged in the outer barrel in a sleeved mode, a lifting device isarranged at the bottom of the inner barrel and connected with a lifting plate, and the lifting plate is connected with a conical platform through a rotating platform. A plurality of through holes areuniformly distributed in the side wall of the inner barrel, a mounting platform is arranged on one side of the outer barrel, and a V-shaped baffle is arranged on the mounting platform. A barrel body of the inner barrel is higher than a barrel body of the outer barrel. The sand washing machine with the automatic feeding function has the advantages of being high in feeding efficiency and good in sand washing effect.

Description

technical field [0001] The invention relates to a sand washing machine, in particular to a sand washing machine with automatic feeding function. Background technique [0002] Machine-made sand generally contains certain impurities such as soil and dust after being crushed, and it needs to be washed before it can be used as a product. The sand washing machine can be divided into many types according to the shape and principle. Among them, the wheel type sand washing machine is a relatively common sand washing machine. Its idea comes from the water wheel. After the group rotates for a week, it is recovered from the sand outlet of the sand washing tank. It can remove the impurities covering the surface of the sand and destroy the water vapor layer covering the surface of the sand. The existing wheel-type sand washing machine needs to manually or use a small excavator to put the broken machine-made sand from the sand inlet end of the sand washing tank into the sand washing tank...

AI Technical Summary

Problems solved by technology

The existing wheel-type sand washing machine needs to manually or use a small excavator to put the broken machine-made sand from the sand inlet end of the sand washing tank into the sand washing tank, and at the same time, it is necessary to shake off part of the soil and dust during the loading process, so as to To realize the preliminary purification of sand and gravel, the efficiency of the feeding process is low, and the dust and soil on the surface of the sand and gravel will still enter the sand washing tank together, and the bottom of the sand washing tank will quickly accumulate mud, making the water in the sand washing tank more turbid. The sand washing effect is not ideal, and in severe cases, it will affect the normal rotation of the impeller group or cause the slurry pump to work overloaded; the existing wheel sand washing machine has a constant speed, and the sand particles are discharged from the sand washing tank after one round of rotation of the impeller group. End recovery, this sand washing method has a short time for sand washing, and it is difficult to wash away stubborn impurities attached to the surface of the sand grains. Moreover, for different sizes of sand, the impeller sets use the same speed, and the sand washing effect will also vary.

Therefore, the existing sand washing machine has the disadvantages of low feeding efficiency and unsatisfactory sand washing effect
