Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a material screening device based on concrete processing. Background Technology

[0002] Concrete is the most widely used building material in modern times and currently the largest category of man-made materials. The current business model of the concrete industry has shifted from the initial extensive to an intensive model. This intensive economic growth model aims to improve economic efficiency and emphasizes the quality of economic growth, characterized by low input and high output. This inevitably leads to the expansion of the service area for concrete batching plant projects.

[0003] When processing concrete materials, it is necessary to screen out the larger particles in the concrete material first to avoid increasing the load on the equipment and reducing production efficiency during the processing. Therefore, we have made improvements to this and proposed a material screening device based on concrete processing.

[0004] Patent CN217700039U discloses a material screening device based on concrete processing, relating to the field of concrete processing technology. It includes a workbench with a base fixedly installed on its lower surface and a vibrating screening mechanism installed on its upper end. A first material screening plate and a second material screening plate are installed at the end of the vibrating screening mechanism furthest from the workbench. The device utilizes a drive motor that, in conjunction with a connecting shaft, drives a gourd-shaped movable block to rotate. This rotation, combined with the resulting vibration, causes a rectangular movable block to move between two springs. Simultaneously, the rotating gourd-shaped movable block, in conjunction with an elliptical movable rod, drives another rectangular movable block to move between two springs. These two rectangular movable blocks then respectively move the first and second material screening plates, thereby screening the concrete material and reducing the load on the equipment during processing.

[0005] However, the transmission mechanisms in this device are all located directly below the screening plate, which can easily cause concrete to fall onto the transmission mechanisms during operation, affecting normal transmission work. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a material screening device based on concrete processing, thus solving the aforementioned technical problems.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a material screening device based on concrete processing, comprising a device body, an inspection cover hinged to the device body, an inlet at the top of the inspection cover, an outlet at the bottom of the device body, two sets of support rails inside the device body, multiple pulleys inside the support rails, mounting frames slidably arranged on both sets of support rails, a first filter screen and a second filter screen respectively installed in the two mounting frames, a box body on one side of the device body, a transmission cavity opened inside the box body, a servo motor installed in the transmission cavity, an installation shaft mounted on the output shaft of the servo motor, two synchronous belts drivingly connected to the installation shaft, two synchronous pulleys rotatably mounted on the device body, two synchronous belts drivingly connected to the two synchronous pulleys respectively, a rotating disk mounted on each of the two synchronous pulleys, a connecting piece rotatably mounted on the rotating disk, and two connecting pieces rotatably mounted on the two mounting frames respectively.

[0008] Preferably, each of the two rotating disks is provided with an eccentric shaft, and the two connecting parts are rotatably mounted on the two eccentric shafts respectively.

[0009] Preferably, both connectors are provided with a connecting shaft, and both mounting frames are provided with a protrusion, with the two connecting shafts rotatably mounted on the two protrusions respectively.

[0010] Preferably, the mounting frame has a placement slot, and the size of the first filter or the second filter is adapted to the placement slot.

[0011] Preferably, a guide frame is provided inside the main body of the device, and the guide frame is disposed between two mounting frames.

[0012] Preferably, the guide frame is installed on the inner wall of the device body through multiple mutually symmetrical connecting frames.

[0013] Preferably, the first filter screen is positioned directly above the second filter screen, and the mesh size of the first filter screen is smaller than that of the second filter screen.

[0014] Compared with the prior art, this utility model provides a material screening device based on concrete processing, which has the following beneficial effects: This utility model, through the setting of a servo motor and mounting frame, allows concrete to be fed into the inlet during operation. The servo motor drives the mounting shaft to rotate, and two synchronous belts on the mounting shaft drive two rotating disks to rotate. In turn, the rotating disks drive the two mounting frames to reciprocate in the horizontal direction through the connecting parts, realizing the screening function. At this time, the concrete can be well screened through the vertically set first and second filter screens. The screened concrete is discharged from the outlet. The setting of the inspection cover facilitates the regular maintenance of the first filter screen, the second filter screen and the transmission structure, ensuring the service life of the device.

[0020] Please see Figure 1-4A material screening device based on concrete processing includes a main body 1, a maintenance cover 2 hinged to the main body 1, a feed inlet 3 at the top of the maintenance cover 2, a discharge outlet 4 at the bottom of the main body 1, two sets of support rails 7 inside the main body 1, multiple pulleys 8 inside the support rails 7, mounting frames 9 slidably arranged on both sets of support rails 7, a first filter screen 10 and a second filter screen 12 respectively inside the two mounting frames 9, a box 6 on one side of the main body 1, a transmission cavity 23 inside the box 6, a servo motor 21 inside the transmission cavity 23, a mounting shaft 22 mounted on the output shaft of the servo motor 21, two synchronous belts 20 connected to the mounting shaft 22, two synchronous pulleys 19 rotatably mounted on the main body 1, the two synchronous belts 20 respectively connected to the two synchronous pulleys 19, a rotating disk 18 mounted on each of the two synchronous pulleys 19, a connecting piece 17 rotatably mounted on the rotating disk 18, and two connecting pieces 17 rotatably mounted on the two mounting frames 9 respectively.

[0021] By incorporating a servo motor 21 and mounting frame 9, concrete can be fed into the inlet 3 during operation. The servo motor 21 drives the mounting shaft 22 to rotate, which in turn drives two rotating discs 18 via two synchronous belts 20 on the mounting shaft 22. This, in turn, causes the rotating discs 18 to drive the two mounting frames 9 to reciprocate horizontally via the connecting piece 17, thus achieving the screening function. The concrete can be effectively screened using the vertically arranged first filter screen 10 and second filter screen 12. The screened concrete is then discharged from the outlet. The inspection cover 2 facilitates regular maintenance of the first filter screen 10, the second filter screen 12, and the transmission structure, ensuring the service life of the device.

[0022] Specifically, in this embodiment, both rotating disks 18 are provided with eccentric shafts, and two connecting parts 17 are rotatably mounted on the two eccentric shafts respectively.

[0023] By setting an eccentric shaft, the connecting piece 17 can perform circumferential reciprocating motion during the rotation of the rotating disk 18.

[0024] Specifically, in this embodiment, both connectors 17 are provided with connecting shafts 16, and both mounting frames 9 are provided with protrusions 15. The two connecting shafts 16 are rotatably mounted on the two protrusions 15 respectively.

[0025] Through the cooperation of structures such as connecting shaft 16 and protrusion 15, the two mounting frames 9 can be driven to perform horizontal reciprocating motion through protrusion 15 when the connecting piece 17 performs circumferential reciprocating motion.

[0026] Specifically, in this embodiment, the mounting frame 9 is provided with a placement groove 11, and the first filter screen 10 or the second filter screen 12 is adapted to the size of the placement groove 11.

[0027] The placement slot 11 allows the first filter 10 and the second filter 12 to be quickly connected to the mounting frame 9, facilitating the quick assembly and disassembly of the first filter 10 and the second filter 12.

[0028] Specifically, in this embodiment, a guide frame 14 is provided inside the main body 1 of the device. The guide frame 14 is located between two mounting frames 9 and is mounted on the inner wall of the main body 1 of the device through multiple mutually symmetrical connecting frames 13.

[0029] By setting the guide frame 14, the falling direction and falling range of the concrete after being screened from the first filter screen 10 can be restricted.

[0030] Specifically, in this embodiment, the first filter 10 is disposed directly above the second filter 12, and the mesh count of the first filter 10 is smaller than that of the second filter 12.

[0031] It should be noted that the servo motor and the electrical components mentioned in the article are all connected to an external controller and mains power. Furthermore, the more detailed working process and basic principle of the screening mechanism are the same as those in the prior application with application number 202220936531.1, which describes a material screening device based on concrete processing. This application will not repeat the details here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
