A sieving equipment that can automatically clean the net

Abstract

The invention discloses sieving equipment capable of automatic cleaning a screen. The sieving equipment comprises two vertically arranged stand columns, a sand sieving frame is rotatably installed between the two stand columns, and a steel wire screen is fixedly installed in the sand sieving frame; first rotating shafts are fixedly installed at two ends of a cross beam on the upper part of the sand sieving frame, and the two first rotating shafts are coaxially arranged and separately rotatably connected to the upper ends of the corresponding stand columns; first sliding grooves are formed in one sides of vertical beams, first sliding blocks are slidably installed in the first sliding grooves, and vertical plates are fixedly installed on the first sliding blocks; and second rotating shaftsare rotatably connected to the middle parts of the vertical plates, and the two oppositely arranged second rotating shafts are separately and correspondingly installed on the inner walls of opposite two sides of the middle part of a storage box. According to the sieving equipment, by reversing the angle of the sand sieving frame, the screen surface which originally faces upward of the steel wire screen is buckled downward, after the sand sieving frame is reversed and vibrated, sand particles stuck in meshes are detached, the detached sand particles fall into a corresponding chamber, and the cleaning efficiency is improved.

Description

technical field [0001] The invention relates to sieving equipment, in particular to a sieving equipment capable of automatically cleaning nets. Background technique [0002] With the development of the economy and the rapid development of science and technology, people's living standards are gradually improving, and the construction of the country is also proceeding rapidly. In real life, a large number of houses, roads and bridges are being built. These projects are collectively referred to as For civil engineering, sand and gravel are used in the construction process of civil engineering, but sometimes the size of the sand and gravel required is different, so a screening device is required to screen the sand and gravel. Most of the sand and gravel used in the construction site are sieve Sand device, but the sand screening efficiency of the current sand screening device is low.

[0002] With the development of the economy and the rapid development of science and technology, people's living standards are gradually improving, and the construction of the country is also proceeding rapidly. In real life, a large number of houses, roads and bridges are being built. These projects are collectively referred to as For civil engineering, sand and gravel are used in the construction process of civil engineering, but sometimes the size of the sand and gravel required is different, so a screening device is required to screen the sand and gravel. Most of the sand and gravel used in the construction site are Sand device, but the current sand screening device has low sand screening efficiency. When the screen mesh is working under high load, the mesh of the screen mesh is easy to block, resulting in a decrease in screening efficiency.
