All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0030] Such as Figure 1 andFigure 2 As shown in the figure, an embodiment of the present utility model provides a monitoring device, which includes a bracket 10, a monitoring unit 20 and a material pushing mechanism 30. Among them, the extending direction of the bracket 10 is the same as the driving direction of the conveyor belt on the conveyor. The monitoring unit 20 includes a camera 21, and the camera 21 is rotatably arranged on the bracket 10, and the camera 21 can monitor the materials on the conveyor belt. The material pushing mechanism 30 includes a material pushing end 301 and a connecting end 302. The connecting end 302 is movably arranged on the bracket 10. The material pushing mechanism 30 can move along the bracket 10. The material pushing end 301 and the connecting end 302 are movably connected. The material pushing mechanism 30 has an extended position and an avoidance position arranged oppositely. When the material pushing mechanism 30 is in the extended position, the material pushing end 301 is close to the conveyor belt to push the materials on the conveyor belt; when the material pushing mechanism 30 is in the avoidance position, the material pushing end 301 is arranged away from the conveyor belt. In this application, the plane where the X-axis and the Y-axis are located is the horizontal plane. Specifically, the Y-axis extends along the length direction, the X-axis extends along the width direction, and the Z-axis extends along the vertical direction.

[0031] Applying the technical solution of the present utility model, when the materials on the conveyor belt are conveyed along with the conveyor belt, the material pushing mechanism 30 is in the avoidance position. When the monitoring unit 20 observes that the materials on the conveyor belt move relative to the conveyor belt, the material pushing mechanism 30 is driven to move along the bracket to a specified position. At this time, the material pushing mechanism 30 is switched to the extended position, and the material pushing end is close to the conveyor belt to push the materials on the conveyor belt. Then, the material pushing mechanism 30 is moved along the driving direction of the conveyor belt, so that the materials on the conveyor belt can maintain a relative static state with the conveyor belt, avoiding the displacement or even dropping of the materials on the conveyor belt, so as to ensure the effective transportation of the materials. Through the above settings, the monitoring unit 20 and the material pushing mechanism 30 cooperate with each other to realize the real-time monitoring of the transportation status of the conveyor belt, and at the same time, ensure the stability of the position of the materials on the conveyor belt, thereby improving the working stability of the conveyor belt and the transportation efficiency of the materials.

[0032] Among them, in this embodiment, the switching between the avoidance position and the extended position of the material pushing mechanism 30 can be realized by the telescopic, rotation or swing of the material pushing end 301 relative to the connecting end 302.

[0033] Such as Figure 2 and Figure 3, the monitoring device further includes a driving part 40. The driving part 40 is arranged on the bracket 10. The driving part 40 is drivingly connected to the connecting end 302, and the driving part 40 can drive the material pushing mechanism 30 to move along the bracket 10. With such an arrangement, the driving part 40 is connected to the connecting end 302 to drive the material pushing mechanism 30 to move, making the movement of the material pushing mechanism 30 more stable and not affecting or interfering with the state of the material pushing mechanism 30. Compared with manually driving the material pushing mechanism 30 to move on the bracket 10, driving the material pushing mechanism 30 to move and change its position by the driving part 40 improves the convenience and flexibility of the device.

[0034] Among them, the driving part 40 includes: a moving seat 41, a first driving member 42, a gear and a rack 43.

The rack 43 is arranged on the bracket 10, and the extending direction of the rack 43 is the same as the extending direction of the bracket 10. The rack 43 meshes with the gear. With the above arrangement, the cooperation of the gear and the rack 43 can ensure the continuity of the movement of the moving seat 41 while the meshing of the gear and the rack 43 is more convenient for adjusting and controlling the moving stroke of the moving seat 41 compared with the cooperation of the pulley and the groove, improving the moving accuracy of the moving seat 41.

[0035] In this embodiment, the first driving member 42 is arranged in the vertical direction, the gear is coaxially arranged with the first driving member 42, and the first driving member 42 is drivingly connected to the gear.

[0036] In this application, the driving part 40 further includes a transmission component. The transmission component is located between the first driving member 42 and the gear. The transmission component is drivingly connected to the driving end, and the first driving member 42 can drive the moving seat 41 to move along the bracket 10 through the transmission component. With the above arrangement, by arranging the transmission component between the first driving member 42 and the gear to change the transmission direction of the force and change the position distribution between components, interference between components during operation is avoided, and the rationality of the component distribution of the device is improved.

[0037] In this embodiment, the transmission assembly includes a worm wheel and a worm, and the worm is coaxially arranged with the driving end of the first driving member 42 and rotates synchronously with the driving end of the first driving member 42.

Through the above arrangement, the structure of the material-digging mechanism 30 is simplified, and disassembly and subsequent maintenance are convenient. Moreover, through the arrangement of the telescopic section 33, the telescopic length of the telescopic member relative to the conveyor belt can be more directly observed, and the adjustment of the deployment position and the avoidance position is convenient. In addition, the above structure is simple and does not take up extra space, so that the material-digging component is more portable and the flexibility of the material-digging component moving on the bracket is improved.

[0041] Among them, the material shifting piece 31 is a square flat plate structure and extends in the vertical direction. With this arrangement, the square structure can fit more closely with the plane of the conveyor belt, and at the same time can more accurately shift the material that has been displaced from the conveyor belt to avoid collision with other materials in a stable transportation state, thereby improving the pertinence and accuracy of the material shifting of the material shifting piece 31.

[0042] In other embodiments, the material-diverting member 31 may also be configured as a circular structure, a triangular structure, or other special-shaped structures.

[0043] Further, the monitoring device further includes a rotating base 15 rotatably arranged on the bracket 10, and the camera 21 is rotatably arranged on the rotating base 15. The rotating base 15 includes a U-shaped groove and a rotating shaft, and the camera 21 is rotatably arranged in the U-shaped groove. In this way, not only can the flexibility of the rotation of the camera 21 be improved, but also the two sides of the U-shaped groove can limit the camera 21 to prevent the camera 21 from tilting during rotation.

[0044] In other embodiments, the rotating base 15 can also be set as a rotating shaft and a rotating table, and the angle of the rotating table relative to the rotating shaft is adjustable. In this way, the camera 21 is fixed on the rotating table, and the rotation angle of the camera 21 can still be controlled through the rotating shaft and the rotating table.

[0045] In this embodiment, the telescopic member is an electric telescopic rod. In other embodiments, the telescopic member can also be set as a combination of a telescopic sleeve and a lead screw, or can be an oil cylinder, a hydraulic cylinder or a cylinder, etc.

[0046] As Figure 2 and Figure 3 shown, the monitoring device further includes a mounting seat 60 arranged on the moving seat 41. The fixed section 32 is passed through the mounting seat 60, and the feeding mechanism 30 is fixedly connected to the moving seat 41 through the mounting seat 60, so as to realize that the moving seat 41 drives the feeding mechanism 30 to move along the bracket 10. At the same time, the mounting seat 60 can also support the feeding mechanism 30.

[0047] Wherein, the bracket 10 further includes a track 11 arranged on the bracket 10. The extending direction of the track 11 is the same as the extending direction of the bracket 10. The moving seat 41 is partially located in the track 11, and the track 11 cooperates with the moving seat 41 to guide the moving seat 41.

[0048] In this embodiment, the moving seat 41 is provided with a groove adapted to the side surface of the track 11 facing the conveyor belt and the rack 43.

[0049] In other embodiments of the present application, rollers can also be arranged at the bottom of the moving seat 41, and the rollers can roll along the track 11 inside the track 11. Through the cooperation of the rollers and the track 11, the movement of the moving seat 41 on the track 11 is realized.

[0050] As Figure 4As shown in the figure, the monitoring unit 20 further includes a dust cover 22. The camera 21 has a lens, and the dust cover 22 is detachably covered on the outer periphery of the lens. Through the above arrangement, the dust cover 22 can protect the lens of the camera 21. While preventing the lens from being damaged by the external environment, it can also avoid dust or water falling on the lens and affecting the shooting effect of the camera 21.

[0051] In this application, the monitoring device further includes a cleaning component. The cleaning component is arranged on the dust cover 22 and is used to clean the dust cover 22. In this embodiment, the dust cover 22 is a transparent dust cover, which is convenient for the camera 21 to monitor the conveyor belt.
