Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1 and 2, the sand multi-stage screening device in the concrete pole production comprises two mounting plates 1 which are vertically arranged on the ground, the surface of the mounting plate 1 is horizontally provided with two channels 2 from top to bottom, a first screen 3 is arranged in the channel 2 at the upper side in a penetrating way, a second screen 4 is arranged in the channel 2 at the lower side in a penetrating way, the two sides of the first screen 3 are connected with a first baffle 6 on the mounting plate 1 through a first compression spring 5, the two sides of the second screen 4 are connected with a second baffle plate 8 on the mounting plate 1 through a second compression spring 7, a first push plate 9 is arranged on one side of the upper surface of the first screen 3, the first push plate 9 is connected with a first telescopic mechanism 10, and a second push plate 11 is arranged on one side of the upper surface of the second screen 4, the second push plate 11 is connected with a second telescopic mechanism 12, and the pore diameter of the first screen 3 is larger than that of the second screen 4.
Preferably, the lower surface of the end part of the first screen 3 is provided with a first bulge 3.1, the upper surface of the end part of the second screen 4 is provided with a second bulge 4.1, a rotating disc 13 is arranged between the first bulge 3.1 and the second bulge 4.1, the outer ring of the rotating disc 13 is uniformly provided with a plurality of collision bulges 14 matched with the first bulge 3.1 and the second bulge 4.1, and the center of the rotating disc 13 is connected with an output shaft of a motor 15. So designed, when the motor 15 is operated, the rotating disk 13 is rotated, so that the collision protrusions 14 are continuously brought into contact with and collide with the first protrusions 3.1 and the second protrusions 4.1, thereby vibrating the first screen 3 and the second screen 4, thereby performing a screening process.
Preferably, the motor 15 is fixed to the support frame 17 by a connection plate 16.
Preferably, the first telescopic mechanism 10 and the second telescopic mechanism 12 are electric push rods or pneumatic telescopic rod structures, and both the first telescopic mechanism 10 and the second telescopic mechanism 12 are fixed on the support rod 18.
Preferably, the upper surface and the lower surface of the first screen 3 are provided with first compression springs 5, and the upper surface and the lower surface of the second screen 4 are provided with second compression springs 7. After the compression spring is arranged, the screen can vibrate up and down in a reciprocating manner, and the vibration process is more stable.
