Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Example one

As shown in FIG. 1-

It is shown, raw materials sieve separator is used in clear water concrete preparation, including filling up foot 1, the top fixed mounting that fills up foot 1 has casing 2, and the right side fixed mounting of casing 2 has grillage 3, and the top fixed mounting of grillage 3 has vibrating motor 4, and vibrating motor 4's output fixed mounting has eccentric block 5, and vibrating motor 4's one end is kept away from to eccentric block 5 rotates with casing 2 to be connected.

The fixed surface of casing 2 installs screen plate 6, sand outlet 7 has been seted up on the front of casing 2, the inner wall fixed mounting of casing 2 has diaphragm 12, set the grit under the screening between screen plate 6 and the diaphragm 12, the top fixed mounting of diaphragm 12 has telescopic link 11, the top fixed mounting of telescopic link 11 has tray 8, row's mouth 9 has been seted up on the tray 8, tray 8 bottom is recessed, it is located tray 8 sunken center to arrange mouth 9, tray 8 is located screen plate 6 under, the center department fixed mounting of tray 8 has connecting rod 10, the surface and the diaphragm 12 sliding connection of connecting rod 10, the bottom fixed mounting of connecting rod 10 has plectane 13, the top fixed mounting of plectane 13 has reset spring 14, reset spring 14 keeps away from plectane 13's one end and diaphragm 12 sliding connection.

In this embodiment, the screening machine operates, gravel enters from one side of the screen plate 6 far away from the sand outlet 7, vibration is generated along with the cooperation of the vibrating motor 4 and the eccentric block 5, the screen plate 6 separates the gravel, the gravel is better screened as the gravel gets closer to the sand outlet 7, but because the amount of the gravel mixed is large, the complete separation of the gravel cannot be ensured due to the length of the screen plate 6, the gravel moves to the position where the screen plate 6 is close to the sand outlet 7, the screened gravel falls into the tray 8, the amount of the gravel falling into the tray 8 is compared with the amount of the gravel flowing out from the sand outlet 9, the amount of the gravel falling into the tray 8 from the screen plate 6 is larger than the amount of the gravel flowing out from the sand outlet 9, the tray 8 accumulates the gravel, the tray 8 pushes the circular plate 13 by using the connecting rod 10, the circular plate 13 stretches the return spring 14, the transverse plate 12 guides the tray 8, the circular plate 13 is pushed by the contact switch 15, the amount of the gravel falling into the tray 8 is smaller than the amount of the gravel flowing out from the connecting rod 10, the circular plate 13 is contacted with the screen switch, the screen plate, the screen position is not pressed by the gravel, and the screen plate is not pressed by the screen, the screen plate, the sand is judged by the sand is not enough.

Example two

As shown in fig. 3-4, a connecting frame 16 is fixedly mounted at the bottom of the horizontal plate 12, a contact switch 15 is fixedly mounted on the surface of the connecting frame 16, an electric push rod 17 is fixedly mounted on the surface of the bottom of the connecting frame 16, a diversion block 18 is fixedly mounted at one end, away from the connecting frame 16, of the electric push rod 17, a round opening inclined to the left and below is formed in the inner wall of the diversion block 18, a conveyor belt 19 is arranged below the diversion block 18, the surface of the diversion block 18 is slidably connected with the sand outlet 7, a large-particle sand outlet is formed in the bottom of the sand outlet 7, and a recovery bin is arranged in the direction, away from the sand outlet 7, of the conveyor belt 19.

In this embodiment, when the grit volume that sieve out in sieve separator sand stone position was many, then disc 13 and contact switch 15 extrude each other, so that electric putter 17 circular telegram stretches out, electric putter 17 passes diversion piece 18, diversion piece 18 blocks up sand outlet 7 completely, the grit after the screening no longer directly flows out from sand outlet 7 this moment, but get into from diversion piece 18's round hole, diversion piece 18's round hole is the slope state, so diversion piece 18 brings the grit to the position of conveyer belt 19, conveyer belt 19 will carry the grit after the screening back to the recovery storehouse of raw materials screening, so that follow-up again screens the grit, thereby loopback the not enough grit of screening degree, compensate because of screening length is not enough to lead to the influence that the screening degree is low.

The foregoing shows and describes the basic principles and principal features of the invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
