An automatic sand screening equipment

Abstract

The invention discloses automatic sand sieving equipment and belongs to the field of building construction equipment. The automatic sand sieving equipment is composed of a support, a control cabinet, a sand storing device, a conveying device, a rocking device and a sand sieving device, wherein the control cabinet is fixedly connected to the lower portion of the support; the sand storing device is fixed to the support; the conveying device is arranged on the left side of the sand storing device and fixed to the support; the conveying device inclines towards the back upper portion by 45 degrees; the rocking device is arranged below one high side of the conveying device; and the sand sieving device is fixed to the support and movably connected with the rocking device. A rocking stepping motor of the automatic sand sieving equipment drives an eccentric wheel to rotate and then drives a rocking support to rock up and down, the sand sieving device is driven to vibrate, sand descends and is layered from sand sieving holes under vibration and can all be smoothly sieved, the sieving effect is good, the sizes of the first sieving holes, the second sieving holes and the third sieving holes are gradually decreased, four-stage layered sieving of the sand is achieved, and the degree of application of the equipment is high.

Description

technical field [0001] The invention relates to an automatic sand screening device, in particular to a device for transporting sand by means of a conveying device, and further screening by a swing device and a sand screening device, which belongs to the field of construction equipment.

[0002] Sand plays an essential role in building construction, road construction, smelting, manufacturing glass and electronic devices, making pottery and porcelain, etc. There are different requirements for the fineness of the sand in different occasions, and it is also necessary to remove impurities from the sand. Filtration, to separate the mixed stones and soil, so it is necessary to filter and screen the sand. The current screening and filtering method for the sand is mainly to set up a bracket screen, and manually use a shovel to shovel the sand for screening, which requires a large workload and high labor intensity. , not only consumes a lot of labor time for workers, but also has low work efficiency and greatly increases the operating cost of the enterprise. Therefore, there is an urgent need for an automatic sand screening equipment, which is currently not available on the market.
