Embodiment 1

[0030] refer to figure 1 , figure 2 and Figure 4-7 , a concrete raw material screening device for water conservancy projects, comprising a frame 1, support legs 2 are fixedly installed at the four corners of the bottom end of the frame 1, and a screen frame 9 is installed on the inner rotation of the frame 1, and a screen mesh is installed on the inner wall of the screen frame 9 , and the side of the screen frame 9 away from the drive block 3 is open-shaped, and the side of the screen frame 9 away from the drive block 3 is fixedly connected with a material guide plate 10, the width of the material guide plate 10 is consistent with the width of the screen frame 9, And the top of material guide plate 10 and the top of sieve frame 9 internal screens are flush and arranged, and one side of frame 1 is fixedly installed with drive motor 22, and the output shaft end of drive motor 22 runs through the side wall of frame 1, and Extending to the inside of the frame 1 is fixedly conn...

Embodiment 2

[0034] refer to figure 2 and image 3 , the inner wall of the frame 1 near the discharge port 16 is provided with an anti-leakage mechanism, the anti-leakage mechanism includes a baffle plate 17, a limit groove 18, a return spring 19, a fixed plate 20 and a limit rod 21, the inner side of the frame 1 A baffle 17 is slidably installed on the wall near the discharge port 16, and a limit groove 18 is provided inside the baffle 17. A fixed plate 20 is fixedly connected to the inner wall of the frame 1 near the side of the baffle 17, and the top of the fixed plate 20 is fixedly connected to the wall. There is a vertical stop bar 21, the end of the stop bar 21 is slidably installed in the inside of the stop slot 18, and a return spring 19 is fixedly connected between the bottom end of the baffle plate 17 and the top end of the fixed plate 20, and resets The spring 19 is sheathed on the rod body of the limiting rod 21 .

[0035] And when the screen frame 9 rotates, it will drive t...

Embodiment 3

[0037] refer to figure 1 , figure 2 and Figure 5-7 The side of the rotating plate 6 away from the output shaft of the drive motor 22 is fixedly connected with a rotating rod 15 distributed perpendicularly thereto, and the rod body of the rotating rod 15 is fixedly connected with a plurality of distribution plates 5 with the same structure.

[0038] When the driving motor 22 drives the rotating plate 6 to rotate, it will drive the rotating rod 15 to rotate, and the rotating rod 15 will drive the material distribution plate 5 to rotate, so that the material distribution plate 5 will evenly place the screened sand grains to prevent it from being located in a certain position. concentrated accumulation.

Abstract

The invention discloses a concrete raw material screening device for a water conservancy project, relates to the field of water conservancy projects, and provides the following scheme aiming at the problem that the service life of a water conservancy project building body is shortened due to the fact that the concrete strength cannot reach the standard due to low concrete raw material screening efficiency in the prior art. The concrete raw material screening device for the water conservancy project comprises a frame, wherein supporting legs are fixedly installed at the four corners of the bottom end of the frame, a screening frame is rotatably installed in the frame, a driving motor is fixedly installed at one side of the frame, and the end part of an output shaft of the driving motor penetrates through the side wall of the frame and extends into the frame to be fixedly connected with a rotating plate; and a moving frame is horizontally and slidably installed at the side, close to the driving motor, of the inner wall of the frame. According to the invention, effective screening treatment can be carried out on concrete raw materials, the phenomenon that screening holes of the screening frame are blocked can be prevented, meanwhile, the phenomenon that sand grains are intensively accumulated at the same position can be avoided, and the normal strength standard of the concrete raw materials is guaranteed.

Description

technical field [0001] The invention relates to the field of hydraulic engineering, in particular to a concrete raw material screening device for hydraulic engineering. Background technique [0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. Also known as water engineering. Water is an indispensable precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's life and production for water resources. Water conservancy projects need to build different types of hydraulic structures such as dams, dikes, spillways, sluices, water inlets, channels, canals, rafts, and fishways to achieve their goals. Water conservancy projects can be divided into: flood con...
