Description

Screen sander

The present invention relates to a screening machine for screening grit for mixing concrete, and more particularly to a screening machine for screening a specific range of grit sizes.

In the construction project, the concrete used for grouting is made of cement, water, sand and stone, and the size of the sand to be mixed for different purposes is different, for example, for powdering. The size of the sand required for the concrete on the wall is small, and the size of the sand required for the coarse embryo concrete used in the main structure is large. Therefore, it is necessary to screen the required particle size with a sieve or sand sieve machine before mixing. Sand grain.

The sand screen of the prior art, such as the Taiwan New Patent Publication No. 207132 and the Taiwan New Patent Publication No. 126862, has a frame body with a replaceable screen and a frame. One side is pivotally connected to a tripod, and the other side of the frame is provided with a grip. In use, the sand to be screened is placed on the frame, and the user holds the handle to shake the frame to sieve out the sand smaller than the mesh of the mesh.

However, the sand sifter must be shaken by the user, and it is quite laborious and inconvenient to screen a certain amount of sand. Furthermore, the supplied sand is usually stored in a wet state, so that the wet sand is often agglomerated, so that the sand after the agglomeration cannot pass through the mesh of the mesh, or even get stuck. In the mesh, it affects its filtering effect.

Another new type of sand screening machine disclosed in Taiwan No. 319672 discloses a sanding machine comprising a body, a vibrator and a screen are arranged on the body, and the sand to be screened is placed on the screen and vibrated by a vibrator. Screens and grit, which in turn sift out sand smaller than the mesh of the mesh.

Although the above-mentioned sand screening machine avoids the manpower shaking and provides the convenience of operation, it still cannot solve the problem that the sand particles are wet and agglomerated, and the sand particles after the moisture can not be screened and used, resulting in waste of materials, and it is necessary to design a kind. A solution to the above problem can be solved.

In view of the problem that the prior art sand screening device cannot screen the agglomerated wet sand, the creation design has a sand screening machine, which can achieve the purpose of screening wet sand.
