Vibrating screen is a screening machine commonly used in industrial and mining enterprises. It is used to classify mixtures of different particle sizes according to particle size. It is also commonly used for dehydration, de-intermediation and cleaning of sludge on the surface of materials. For sand and gravel production lines, the technical level and quality of screening equipment are related to the quality of process effects and production efficiency, which directly affects the economic benefits of the enterprise.

[0003] After searching, it was found that the Chinese patent with announcement number CN220496888U discloses a recycled concrete raw material crushing and screening device, including a crushing and screening device bucket body and a first screen layer arranged at the middle position of the crushing and screening device bucket body; a sliding support block is provided at the upper end position of the connecting frame, and an extrusion middle block is provided at the rear end position of the sliding support block, the interior of the extrusion middle block is provided with a connecting external thread, and the lower end position of the connecting external thread is provided with a plug pin, the plug pin is rotatably connected to the extrusion middle block through the connecting external thread, and a second connecting spring is provided at the position of the extrusion middle block in the sliding support block. The position is adjusted by moving the sliding support block, and the plug pin is moved downward by pressing the extrusion middle block, and the sliding support block is moved to the same vertical position as the raw material of the mesh hole, and then the extrusion middle block is pressed so that the plug pin pierces the raw material of the mesh hole. The utility model makes it more convenient for users to clean the raw materials stuck in the mesh hole.

[0004] The above utility model has the following problems:

[0005] 1. The existing technology for processing and screening concrete raw materials has a simple structure and lacks a shock-absorbing structure. When screening concrete, the concrete mostly falls on the discharge conveyor belt in sections, which generates impact force on the conveyor belt and shortens its service life.

[0006] 2. The existing technology for concrete raw material processing and screening devices has poor protection effect, so that the raw materials are exposed to the outside for screening, which easily causes the dust inside the raw materials to be raised in the air, affecting the processing environment and posing certain safety hazards to operators.

[0007] Therefore, those skilled in the art provide a raw material screening and slag removal device for concrete production to solve the problems raised in the above background technology. Utility Model Content

[0008] The purpose of the utility model is to provide a raw material screening and slag removal device for concrete production to solve the problems raised in the above background technology.

[0009] To achieve the above purpose, the present invention provides the following technical solutions:

[0010] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location.

[0011] As a further solution of the present invention: a groove plate is fixedly connected to the lower surface of the support plate, an embedding groove is opened on the side wall of the groove plate, and a reset block is slidably connected to the inner side wall of the embedding groove.

[0012] As a further solution of the present invention: a second reset spring is fixedly connected between the reset block and the embedding groove, and a connecting rod is hinged between the second reset spring and the damping spring.

[0013] As a further solution of the present invention: the transmission mechanism includes a fixed rod, a fixing part, a sliding sleeve, a sliding rod, a guide wheel, an impact head, a first return spring, a rotating shaft and a cam, the inner side wall of the shell is fixedly connected to the fixed rod, the surface of the fixed plate is fixedly connected to a plurality of groups of fixing parts, the surface of the fixing part is embedded with a sliding sleeve, and the inner side wall of the sliding sleeve is slidably connected to the sliding rod.

[0014] As a further solution of the present invention: the top end of the slide rod is fixedly connected to a collision head, a first return spring is fixedly connected between the collision head and the fixing member, the first return spring is sleeved outside the slide rod, and the bottom end of the slide rod is rotatably connected to a guide wheel.

[0015] As a further solution of the present invention: the inner side wall of the shell is rotatably connected to a rotating shaft, a plurality of groups of cams are fixedly connected to the surface of the rotating shaft, and the cams are in contact with the guide wheel.

[0016] As a further solution of the present invention: a driving motor is fixedly connected to the surface of the shell, and a power output end of the driving motor is fixedly connected to one end of the rotating shaft.

[0017] As a further solution of the present invention: a controller is fixedly connected to the side wall of the shell, and the servo motor and the drive motor are electrically connected to an external power supply through the controller.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The screened concrete falls on the conveyor belt, and the servo motor can be controlled by the controller to operate. The power output end of the servo motor rotates to drive the first bevel gear to rotate, and the rotation of the first bevel gear drives the second bevel gear to rotate. The rotation of the second bevel gear drives the conveyor roller to rotate, and the rotation of the conveyor roller drives the conveyor belt to move. The concrete is passed out of the shell through the movement of the conveyor belt. At the same time, the receiving plate is supported by the combination of the damping spring, the groove plate, the reset block, the second reset spring and the connecting rod, which plays a shock-absorbing and buffering role for the entire structure. The vibration accompanied by the falling concrete is transmitted to the damping spring, causing the spring inside the damping spring to elastically deform, absorb part of the energy, and generate a reaction force. At the same time, the internal damper consumes energy through friction and fluid resistance, reducing the energy of the vibration system. Combined with elastic deformation and energy dissipation, the damping spring can effectively reduce the vibration amplitude of the structure, reduce the impact of the impact on the entire structure, and under the action of the damping spring, it can effectively reduce the damage caused by vibration, provide shockproof protection, ensure the stability of the entire structure, and ensure its service life.

[0020] 2. The driving motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the rotation of the cam. When the cam rotates, it drives the guide wheel to move, and the movement of the guide wheel drives the slide bar to move, and the movement of the slide bar drives the impact head to move, so that the impact head can move up and down repeatedly. The cams set at different inclination angles make the impact head rise and fall in a wave-like manner, and the sieve plate is vibrated by the wave-like up and down movement of the impact head, so that the sieve plate vibrates continuously. The continuous vibration of the sieve plate is used to screen and remove slag from the concrete. The concrete passing through the sieve plate falls onto the conveyor belt and passes out of the shell through the conveyor belt. The screening process is carried out inside the shell, which can effectively reduce dust and protect the concrete processing environment. BRIEF DESCRIPTION OF THE DRAWINGS
