Swinging sand sieving device for building

Abstract

The invention discloses a swinging sand sieving device for a building. The swinging sand sieving device for the building comprises a base and a push plate, wherein a first support rod is fixed to theupper end of the base, and a joint plate is connected to the middle part of the left side of the first support rod; a bolt is inlaid in the inner side of the joint plate, and a backing plate is fixedto the right side of the joint plate; a spring is installed at the top end of the backing plate, and a first sieving screen is arranged at the top end of the spring; an adjustable rotary shaft is inlaid in the upper end of the front surface of the first support rod, and a second support rod is connected to the top end of the first support rod; a push-pull rod is inlaid in the middle part of the inner side of the second support rod, and a second sieving screen is installed at the middle part of the right side of the second support rod; and a baffle is fixed to the upper end of the second sieving screen, and a connection shaft is fixed to the upper end of the baffle. The swinging sand sieving device for the building is provided with a base, and the length of the base is greater than the length of the first support rod, so that the whole device is more stable during working.

Description

technical field [0001] The invention relates to the technical field of construction sand screening devices, in particular to a shaking type sand screening device for construction. Background technique [0002] In the construction industry, sand is one of the main building materials. However, the raw materials of sand are relatively rough, and generally need to be filtered before use. Due to the relatively large amount of sand used in construction sites, sand screening devices are widely used in construction sites. [0003] Construction sand screening devices on the market usually have several poles to support a screening net, but this can only be used for simple screening of sand particles, and can only be divided into two categories, so that the screening of sand particles is not thorough, and in the screening When the sand is under less force, it is not easy to separate from the screen. When the sand accumulates too much, the screen will be blocked. Therefore, we propose ...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of swaying type sand screening device for construction, to solve the above-mentioned background technology, there are usually several poles to support a screening net, but this can only carry out simple screening of sand grains, and can only Divided into two categories, so that the screening of sand particles is not thorough, and when screening, the sand particles are less stressed, and it is not easy to separate from the screen mesh. When the sand particles accumulate too much, the screen mesh will be blocked.
