Embodiment 1

[0022] see Figure 1-3 A sand screening device for construction engineering, comprising a sand screening bottom frame 1, a sand screening box body 2 with a number of sand screening holes evenly arranged at the bottom, and a collection frame 3 detachably installed on the inner wall of the bottom of the screening sand bottom frame 1, and a sand screening box 3. The side wall of the sand sieve bottom frame 1 opposite to the box body 2 is provided with an escape groove 4, and the side wall of the sieve sand box body 2 is fixedly connected with a feed pipe 5 with a valve; The side inner wall of the bottom frame 1 is fixedly installed with symmetrically arranged guide partitions 6, and a sand groove 9 is formed between the symmetrically arranged guide partitions 6, and symmetrically arranged irregularities are fixed on the symmetrically arranged guide partitions 6. Bumps 7, the upper surface of the irregular bumps 7 is irregular and uneven, and a number of movable balls 8 are embedd...

Embodiment 2

[0032] This embodiment is further improved on the basis of the embodiment, and the improvement lies in that: the bottom of the sand screening bottom frame 1 is evenly arranged with a number of shock-absorbing and anti-skid skirting feet 45; Placement stability.

[0033] The working principle of this embodiment is: by setting the shock-absorbing and anti-skid kicks 45, the placement stability of the whole device is improved.

Abstract

The invention discloses a sand screening device for construction engineering, which comprises a sand screening bottom frame, a sand screening box body and a collection frame. Irregular bumps, the top of the sand screening bottom frame is provided with a power assembly, and the sand screening box is provided with an extruding sand turning assembly; the extruding sand turning assembly includes a drive motor, a first rotating shaft and a second Two rotating shafts and extruding drive plate; the present invention squeezes and separates the bonded sand blocks in the sand screening box by setting irregular bumps, driving motors, the first rotating shaft and the second rotating shaft, and extruding the driving plate. The bonded sand blocks in the sand screening box are broken up and separated, and the sand located on the inner wall at the bottom of the sand screening box is turned; The integrated sand screening structure can effectively improve the sand screening effect and avoid the existence of bonded sand blocks.

Description

technical field [0001] The invention relates to the related field of construction, in particular to a sand screening device for construction engineering. Background technique [0002] Sand is the main component of concrete and mortar. In construction engineering and hydraulic engineering, sand is widely used. The prepared sand can not only save cement, but also improve the density and strength of concrete and mortar. It is necessary to screen the sand according to the specific project needs, so as to achieve the required characteristics of materials such as concrete and ensure the construction quality. [0003] However, the existing sand screening equipment for construction engineering has a single structure, usually a single filter plate is shaken by a power component to achieve screening, but there may be bonded sand blocks, resulting in incomplete screening and waste. Based on this, we A sand screening device for construction engineering is proposed to solve the above pr...
