Description

Technical Field

[0001] This utility model relates to the technical field of construction machinery, specifically to a material feeding bridge device. Background Technology

[0002] In building, mining, and tunnel construction, the loading of shotcrete machines typically involves manual handling or direct dumping by a forklift. Traditional methods have significant drawbacks: manual loading is inefficient and labor-intensive, while direct dumping by a forklift can lead to material splashing, uneven accumulation, and even equipment damage. Existing transition bridge mechanisms are mostly fixed designs, lacking flexibility in height and angle adjustment, making it difficult to adapt to different hopper models. Furthermore, they lack effective buffering and limiting devices, which can cause mechanical impact during rapid unloading by the forklift, affecting equipment lifespan. These problems severely restrict the improvement of construction efficiency and the guarantee of operational safety.

[0003] A search revealed Chinese patent publication number CN203373994U, which discloses a feeding transition bridge mechanism for a shotcrete machine. This mechanism includes two sets of connecting frames, each with a hook on both sides. A fixing hook, cooperating with the hooks, is located on the outer side of the rear crossbeam of the frame. A column is mounted on the rear crossbeam, and a rope guide wheel is mounted on the column. One end of the rope is fixed to the connecting frame, and the other end passes around the rope guide wheel and connects to the frame. The advantages of this invention are: the transition bridge mechanism allows the loader to directly dump raw materials into the hopper, greatly accelerating the feeding speed, reducing labor intensity, and improving work efficiency.

[0004] However, the rigid connection between the hook and the fixed hook lacks cushioning and is easily deformed by the impact of the forklift; the lifting rope is inconvenient to adjust and cannot adapt to hoppers of different heights, resulting in insufficient flexibility. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding bridge device that solves the problems of existing devices lacking dynamic adjustable limiting function and adaptive angle adjustment capability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding bridge device, comprising a feeding port, a limiting device, and an adjusting device. Both the adjusting device and the limiting device are connected to the outer wall of one side of the feeding port via second mounting plates. Two symmetrical second mounting plates are provided on one side of the feeding port. The second mounting plates are fixedly connected to first mounting plates. Guide rails are connected within the two first mounting plates. Second sliders are provided within the guide rails. A limiting rod is fixedly connected to the outer wall of the upper end of each second slider. The limiting rod is equipped with a rotating cylinder. The limiting rod and the rotating cylinder are connected via ball bearings. The ball bearings within the rotating cylinder and the limiting rod allow the rotating cylinder to rotate when in contact with the material, reducing friction on the material and simultaneously providing limiting and guiding functions.

[0007] In use, rotating the first knob rotates the first lead screw, which in turn moves the first slider on the guide rail, thereby changing the position of the limiting rod connected to the first slider. Rotating the second knob rotates the second lead screw, which in turn moves the second slider on the guide rail, thereby changing the position of the limiting rod connected to the second slider. The two knobs control the movement of the two sliders respectively, which can effectively limit and guide the material. The drive motor rotates the rotating rod, which drives the rotating arm fixedly connected to it. The roller on the rotating arm rotates with the rotating arm, thereby changing the material conveying angle.

[0008] Preferably, the guide rail is provided with a first lead screw, the first lead screw is provided with a through groove, the through groove is provided with a second lead screw, the outer wall of the second lead screw is provided with a second slider, the outer wall of the first lead screw is provided with a first slider, the second lead screw passes through the through groove in the first lead screw, and the outer wall thread is exposed on the side of the limiting block facing the second slider.

[0009] Preferably, both the first lead screw and the second lead screw are connected to the limiting block, and both ends of the limiting block are provided with ball bearings, so that the first lead screw and the second lead screw can rotate.

[0010] Preferably, a first knob is fixedly connected to one end of the first lead screw, and a second knob is fixedly connected to one end of the second lead screw. Both the first and second knobs are provided with handles on one side for easy operation by staff.

[0011] Preferably, a mounting bracket is fixedly connected to one side of the feed inlet, and a rotating motor is fixedly connected to one side of the mounting bracket. The output shaft of the rotating motor is fixedly connected to the rotation center of the rotating rod. The rotating rod is connected to the second mounting plate through ball bearings. The connection between the rotating rod and the second mounting plate through ball bearings ensures that the rotating rod can rotate smoothly while providing stable support for the rotating arm.

[0012] Preferably, the rotating rod is fixedly connected to the rotating arm, the rotating arm is provided with a crossbar, the rotating arm is provided with a connecting rod, the outer wall of the connecting rod is fitted with a roller, and ball bearings are provided at the connection points of the roller and the two ends of the connecting rod. The crossbar acts as a barrier to prevent some materials from falling directly from between the rotating arms.

[0013] Preferably, a support plate is fixedly connected to the outer wall of one side of the feed port. The support plate is located below the rotating arm and provides support to reduce the pressure on the rotating arm.

[0014] This utility model provides a feeding bridge device. It has the following beneficial effects:

[0015] 1. This feeding bridge device uses a dual-slider independent adjustment design. The first and second sliders are driven by a first lead screw and a second lead screw, respectively, allowing for individual or synchronous adjustment of the limit rod position. This structure enables the device to adapt to materials of different sizes and shapes; for example, the limit distance can be increased for large materials and decreased for small materials, ensuring stable guidance. The rotating drum uses ball bearings for connection, resulting in extremely low frictional resistance when materials are in contact, preventing jamming or scratches. Furthermore, the high precision of the lead screw transmission, combined with the rigid support of the guide rail, ensures stable and reliable limit adjustment, effectively improving feeding accuracy and efficiency, and making it suitable for various industrial conveying scenarios.

[0016] 2. This feeding bridge device uses a rotating motor to drive a rotary rod, which in turn rotates the entire rotating arm to achieve adjustable conveying angle. The rollers on the rotating arm are connected by bearings, ensuring flexible rotation, reducing material friction, and guaranteeing a smooth transition. Crossbars provide additional protection to prevent material slippage. This design is particularly suitable for applications requiring changes to the material's trajectory, such as switching from horizontal conveying to inclined feeding, or adjusting the material stacking position. Support plates enhance structural stability, allowing the rotating arm to maintain a precise angle even under load. The overall structure is compact and easy to adjust, significantly improving the flexibility and automation of the production line. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model provides a feeding bridge device, including a feeding port 1, a limiting device 2, and an adjusting device 3. The adjusting device 3 and the limiting device 2 are both connected to the outer wall of one side of the feeding port 1 through a second mounting plate 19. Two symmetrical second mounting plates 19 are provided on one side of the feeding port 1. The second mounting plates 19 are fixedly connected to the first mounting plates 8. The two first mounting plates 8 are connected to guide rails 10. The guide rails 10 are provided with second sliders 9. The upper outer wall of the second sliders 9 is fixedly connected to a limiting rod 18. The limiting rod 18 is provided with a rotating cylinder 17. The limiting rod 18 and the rotating cylinder 17 are connected by ball bearings. In use, the material moves from the feeding port 1 to the limiting device 2. After contacting the rotating cylinder 17, it is limited. At the same time, the rotating cylinder 17 can rotate axially to reduce the friction on the material, thus guiding and limiting the material at the same time.

[0027] Example 2

[0028] Please see Figure 1-5 In this embodiment, the guide rail 10 is provided with a first lead screw 16, the first lead screw 16 is provided with a through groove 14, the through groove 14 is provided with a second lead screw 15, the outer wall of the second lead screw 15 is provided with a second slider 9, and the outer wall of the first lead screw 16 is provided with a first slider 24. In use, the lower end of the second slider 9 is connected to the second lead screw 15 through a threaded seat. The rotation of the second lead screw 15 can make the second slider 9 move laterally, thereby adjusting the position of the limiting rod 18 and the rotating cylinder 17 connected to the second slider 9.

[0029] Both the first lead screw 16 and the second lead screw 15 are connected to the limiting block 11. In use, the limiting block 11 can block the movement of the first slider 24 and the second slider 9 to prevent them from falling off. At the same time, it makes the rotation of the first lead screw 16 and the second lead screw 15 independent and does not affect each other.

[0030] The first lead screw 16 is fixedly connected to one end of the first knob 12, and the second lead screw 15 is fixedly connected to one end of the second knob 13. In use, rotating the first knob 12 can rotate the first lead screw 16, and rotating the second knob 13 can rotate the second lead screw 15.

[0031] A mounting bracket 20 is fixedly connected to one side of the feed inlet 1, and a rotating motor 21 is fixedly connected to one side of the mounting bracket 20. The output shaft of the rotating motor 21 is fixedly connected to the rotation center of the rotating rod 23. The rotating rod 23 is connected to the second mounting plate 19 through a ball bearing. When in use, driving the rotating motor 21 can make the rotating rod 23 rotate.

[0032] The rotating rod 23 is fixedly connected to the rotating arm 22. The rotating arm 22 is provided with a crossbar 4 and a connecting rod 7. A roller 6 is sleeved on the outer wall of the connecting rod 7. Ball bearings are provided at the connection points between the roller 6 and the two ends of the connecting rod 7. When in use, the rotation of the rotating rod 23 can make the rotating arm 22 rotate together, thereby achieving the effect of changing the conveying angle.

[0033] A support plate 5 is fixedly connected to the outer wall of one side of the feed port 1. When in use, the support plate 5 can not only provide support for the rotating arm 22, but also provide a limiting effect during transportation to prevent the roller 6 from sagging excessively, making it convenient to handle and place.

[0034] Instructions for use: When using this device, rotating the first knob 12 causes the first lead screw 16 to rotate, which in turn drives the first slider 24 to move on the guide rail 10, thereby changing the position of the limiting rod 18 connected to the first slider 24. Rotating the second knob 13 causes the second lead screw 15 to rotate, which in turn drives the second slider 9 to move on the guide rail 10, thereby changing the position of the limiting rod 18 connected to the second slider 9. The two knobs control the movement of the two sliders respectively, which can effectively limit and guide the material. Driving the rotating motor 21 causes the rotating rod 23 to rotate, which drives the rotating arm 22 fixedly connected to it. The roller 6 on the rotating arm 22 rotates with the rotating arm 22, thereby changing the material transmission angle.
