Detailed Description

The principles and features of the present utility model are described below with reference to the drawings, the illustrated embodiments are provided for illustration only and are not intended to limit the scope of the present utility model.

As shown in fig. 1 to 3, a concrete slurry screening device of the present embodiment includes a screw conveyor 1 and a linear vibration screen 2 disposed below a discharge port 10 of the screw conveyor 1, the linear vibration screen 2 including a screen 21, a spring assembly 20 for supporting the screen 21, and a vibration motor 22 cooperating with the screen 21, the screen 21 being preferably disposed obliquely.

A linear reciprocating mechanism 3 is arranged between the discharge hole 10 and the linear vibrating screen 2.

The linear reciprocating mechanism 3 comprises a reciprocating screw 30, a sliding block 31 and a device for preventing the sliding block 31 from rotating, wherein the discharging hole 10 is connected with a flexible pipeline 11, and the flexible pipeline 11 can be a flexible pipeline 11 commonly used in the field such as a telescopic metal hose and a plastic hose. The lower end of the flexible pipeline 11 is fixedly connected to the sliding block 31, and the driving motor 12 of the screw conveyor 1 is connected with the reciprocating screw 30 through a transmission mechanism and is used for driving the reciprocating screw 30 to rotate.

The means for preventing the rotation of the slider 31 comprises a slide bar 34 parallel to the reciprocating screw. The flexible pipe 11 is connected to the sliding rod 34 through a sliding member 33, preferably, the sliding member 33 is a pipe fitting capable of being sleeved on the sliding rod 34, and other structural members capable of being slidingly matched with the sliding rod 34, such as a C-shaped clamping block, which are common in the art, can be adopted.

The reciprocating screw 30 is a screw capable of reciprocating the slider 31 without changing the rotational direction of the spindle. The reciprocating screw 30 is a form of a stereoscopic cam pair, which is represented by two thread grooves of the same pitch and opposite directions of rotation, and both ends are connected by an excessive curve. By the rotation of the screw, the side of the spiral groove pushes the slider 31 placed in the spiral groove to axially reciprocate.

The present embodiment gives a preferred form in which the screw conveyor 1 is arranged in such a way that it extends obliquely upwards in the conveying direction, so that the feed opening is in a lower position, into which concrete is to be fed. The drive motor 12 is provided at the rear end of the screw conveyor 1. The reciprocating screw 30 is arranged along the horizontal direction, the transmission mechanism comprises a belt transmission assembly 37, a driving bevel gear 36 and a driven bevel gear 35 which are meshed with each other, the shaft of the driven bevel gear 35 is fixedly connected with the coaxial center of the reciprocating screw 30, and the shaft of the driving bevel gear 36 is connected with the driving motor 12 through the belt transmission assembly 37. Specifically, the drive bevel gear 36 has a first pulley on its shaft, a second pulley on its output shaft, and a belt around the first and second pulleys.
