Embodiment 1

[0033] refer to Figure 1-Figure 5 , a continuous type sand screening device for construction engineering, comprising a first support frame 1, a screen 3 is rotatably connected to both sides of the first support frame 1, and both sides of the screen 3 are fixed with sliding shafts 303 by bolts. One side of a support frame 1 is fixed with an arc-shaped slideway 2 by bolts, and the arc-shaped slideway 2 is slidably connected with the sliding shaft 303, and the connection mode of the arc-shaped slideway 2 and the sliding shaft 303 can be slidably connected to the screen cloth 3. To guide the effect, the upper surface of the screen 3 is rotatably connected with a plurality of rolling shafts 304, and the upper surface of the screen 3 is fixed with a baffle 301 by bolts, and the sand and gravel on the screen 3 are blocked by the baffle 301 to prevent Sand and gravel fall from both sides of the screen 3, one side of the baffle plate 301 is fixed with a guide block 302 by bolts, one s...

Embodiment 2

[0037] refer to Figure 6-Figure 7 , a continuous type sand screening device for construction engineering, including a sliding rod 13 slidingly connected to both sides of the filter plate 8, one end of the sliding rod 13 is fixed with a sieve moving plate 1301 by bolts, and the sieve moving plate 1301 is slidably connected with the filter bar 9 , use the sliding rod to drive the screen moving plate to move to one side, so as to move the large sand and gravel to one side of the filter plate, and in the process, use the curved structure design of the screen moving plate to move the sand and gravel Rolling, so that sand and gravel can be separated from fine sand, one end of the sliding rod 13 is fixed with a pull rod 1302 by bolts.

[0038] The working principle of this embodiment: when in use, pull the sliding rod 13 outward, and use the sliding rod 13 to drive the sieve moving plate 1301 to move to one side, thereby moving the large sand and gravel to one side of the filter pla...

Abstract

The invention relates to the technical field of sand screening, and discloses a continuous sand screening device for constructional engineering. The continuous sand screening device comprises first supporting frames, a screen is rotationally connected to two sides of the first supporting frames, sliding shafts are fixedly connected to two sides of the screen, arc-shaped slideways are fixedly connected to one sides of the first support frames, and the arc-shaped slideways are connected with the sliding shafts in a sliding manner. A plurality of rolling shafts are rotationally connected to the upper surface of the screen, baffles are fixedly connected to the upper surface of the screen, flow guide blocks are fixedly connected to one sides of the baffles, a screening box is fixedly connected to one side of the first supporting frames and makes contact with the screen, and arc-shaped screening plates are rotationally connected to the inner walls of the two sides of the screen. A plurality of crushing cones are integrally formed on the upper surface of the arc-shaped screening plates, and a plurality of screening holes are formed in the upper surface of the arc-shaped screening plates. According to the The problem that an existing machine is poor in separation effect on sand and stone blocks which are bonded into blocks is solved, waste of a large amount of sand is reduced, and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of sand screening, in particular to a continuous sand screening device for construction engineering. Background technique [0002] Sand is one of the basic building materials commonly used in building construction. It is generally used in conjunction with cement and concrete. The sand needs to be screened before use. The purpose is to screen out large particles and stones in the sand. [0003] At present, most of the existing continuous sand screening devices for construction projects have the following deficiencies: in the process of use, the sand and stones that are bonded into blocks are often screened out together, and the existing machines are not suitable for the bonded blocks. The separation effect of sand and stones is poor, resulting in a large amount of waste of sand, which affects economic benefits. In summary, most of the existing continuous sand screening devices for construction projects cannot...
