As a further scheme of the utility model, a discharge hole is formed in the bottom side of the workbench.

Compared with the prior art, the utility model has the beneficial effects that:

1. through being provided with reinforcing bar cross net, reinforcing bar cross net can filter the concrete raw materials, makes the great raw and other materials of water content, artifical sand material, can fall into the hopper through reinforcing bar cross net inside to the concrete satisfies the production specification.

2. Through being provided with the bank of screens, the bank of screens can vibrate under vibrating motor's vibration to make the bouncing ball bullet move, the bouncing ball can strike reinforcing bar cross net, avoids the too much concrete raw materials of water content to block up reinforcing bar cross net, and the spring and the vibration pad of setting have the function of damping, reduce the vibration that causes the material hopper.

Detailed Description

Referring to fig. 1 to 3, in the embodiment of the utility model, the novel concrete vibrating screen includes a workbench 1 and a vibrating motor 9, a working chamber 2 is arranged inside the workbench 1, a square pipe 3 is arranged inside the working chamber 2, a steel bar cross net 301 is welded between the square pipes 3, a screen frame 302 is bolted on the lower side of the square pipe 3, a plurality of screen holes 304 are arranged on the bottom plate of the screen frame 302, a plurality of rebounding plates 303 are fixedly connected inside the screen frame 302, a plurality of elastic balls 305 are arranged between the rebounding plates 303, a material hopper 8 is arranged on the lower side of the screen frame 302, a material groove 801 is formed in the material hopper 8, and the vibrating motor 9 is installed on the bottom side of the screen frame 302.

As shown in fig. 2, the square tubes 3 are welded to each other in a rectangular shape.

As shown in fig. 3, the rebound board 303 is curved to increase the ability of the bouncer 305 to impact the steel wire cross 301.
