Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of elevator technology, and more specifically, to an elevator feeding device. Background Technology

[0002] Bucket elevators are fixed mechanical conveying equipment, mainly suitable for the continuous vertical lifting of powdery, granular and small lump materials. They can be widely used in the lifting of bulk materials in feed mills, flour mills, rice mills, oil mills, starch mills, grain depots, ports and docks of various sizes. Before the elevator transports materials, a feeding device is required to supply them.

[0003] The existing feeding device pours the material into the device through the inlet, and then the drive motor drives the sprocket and chain to rotate, so that the discharge mechanism rotates to discharge the material. However, the material tends to accumulate after entering the device along the feed pipe, making it difficult for the material to pass through the device and enter the hopper.

[0004] The aforementioned feeding device is prone to material accumulation after entering the device, making it difficult for some material to enter the hopper, thus reducing the device's effectiveness. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a feeding device for a hoist, which solves the technical problem in the prior art that materials tend to accumulate inside the device after entering, making it difficult for some materials to enter the hopper.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a feeding device for a hoist, which includes a connecting frame, and further includes a drive shaft, a sprocket, a discharge frame, a first discharge port, a feed pipe, a fixed frame, a second discharge port, a connecting strip, a protective box, a transmission mechanism, a reset mechanism, and a moving mechanism; The drive shaft is rotatably connected within the connecting frame. A sprocket is mounted on the outer surface of the drive shaft, and a discharge frame is mounted on the outer end of the drive shaft. The first discharge port is mounted on the outer surface of the discharge frame. The outer surface of the feed pipe extends through the connecting frame, and the outer end of the feed pipe is connected to a fixed frame. The outer surface of the fixed frame is connected to a second discharge port. The connecting strip is mounted on the upper surface of the fixed frame, and a protective box is slidably connected to the outer side of the connecting strip. The transmission mechanism is located within the discharge frame, and a reset mechanism and a moving mechanism are located inside the protective box.

[0007] In a preferred embodiment of the feeding device for the elevator described in this utility model, in order to better transmit kinetic energy, the transmission mechanism includes a first transmission gear, a transmission rod, a second transmission gear, and a cam. The first transmission gear is installed inside the discharge frame, the transmission rod is rotatably connected inside the protective box, a cam is installed on the outer surface of the transmission rod, the second transmission gear is installed at the outer end of the transmission rod, and the first transmission gear meshes with the second transmission gear.

[0008] In a preferred embodiment of the feeding device for the elevator described in this utility model, in order to prevent the device from getting stuck during operation, the reset mechanism includes a reset spring and a connecting column. The reset spring is installed inside the protective box, and the connecting column is installed at the inner end of the reset spring.

[0009] In a preferred embodiment of the feeding device for the elevator described in this utility model, in order to better disperse the material in the fixed frame, the moving mechanism includes a moving frame, a moving plate and an auxiliary rod. The moving frame is installed on the inner side of the connecting column, the moving plate is installed on the inner side of the moving frame, and the auxiliary rod is rotatably connected inside the moving frame.

[0010] In a preferred embodiment of the feeding device for the elevator described in this utility model, in order to prevent material from sticking to the inner wall of the discharge frame, a cleaning brush is installed on the outer side of the protective box, and the auxiliary rod is slidably connected to the inside of the protective box.

[0011] In a preferred embodiment of the feeding device for the elevator described in this utility model, in order to prevent the connecting column from shifting during movement, a movable block is slidably connected to the inner wall of the top of the protective box, a movable rod is installed on the lower surface of the movable block, and the upper surface of the connecting column is installed at the bottom end of the movable rod.

[0012] In a preferred embodiment of the feeding device for the elevator described in this utility model, in order to accelerate the movement of materials, an auxiliary frame is installed on the outer surface of the auxiliary rod, and a disintegrating frame is installed on the outer surface of the auxiliary frame.

[0013] In a preferred embodiment of the feeding device for the elevator described in this utility model, in order to better feed material into the device, the outer surface of the feed pipe is connected to a feed frame, and an upper cover is installed on the upper surface of the connecting frame.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the transmission mechanism drives the moving mechanism to move in and out, so that the auxiliary frame drives the dispersing frame to disperse the material in the fixed frame. Compared with the direct material conveying of the prior art, this device can clear the accumulated material and reduce the impact of material accumulation in the fixed frame on the normal operation of the device.

[0015] In this disclosure, the moving plate moves outward, driving the moving frame outward, and then the return spring pushes the connecting column inward, allowing the auxiliary rod to reciprocate along the inside of the protective box.

[0025] like Figures 1-4 As shown, it illustrates a feeding device for a hoist in one embodiment of the present disclosure, which includes a connecting frame 1, a transmission shaft 2, a sprocket 3, a discharge frame 4, a first discharge port 5, a feed pipe 6, a fixing frame 7, a second discharge port 8, a connecting strip 9, a protective box 10, a transmission mechanism, a reset mechanism, and a moving mechanism. like Figures 1-3As shown, the drive shaft 2 is rotatably connected to the connecting frame 1. A sprocket 3 is installed on the outer surface of the drive shaft 2. The sprocket 3 meshes with the chain set at the external elevator hopper. During the movement of the chain, the sprocket 3 is driven to rotate. A discharge frame 4 is installed at the outer end of the drive shaft 2. A circular hole is opened on the right side of the discharge frame 4. The diameter of the circular hole is larger than the diameter of the fixed frame 7. The first discharge port 5 is installed on the outer surface of the discharge frame 4. The outer surface of the feed pipe 6 passes through the connecting frame 1. The outer end of the feed pipe 6 is connected to the fixed frame 7. The outer surface of the fixed frame 7 is connected to the second discharge port 8. The length and width of the first discharge port 5 and the second discharge port 8 are the same. A connecting strip 9 is installed on the upper surface of the fixed frame 7. A protective box 10 is slidably connected to the outer side of the connecting strip 9. The connecting strip 9 is a T-shaped strip. A T-shaped groove is opened inside the protective box 10. The T-shaped groove is slidably connected to the connecting strip 9. The transmission mechanism is set inside the discharge frame 4. A reset mechanism is set inside the protective box 10. A moving mechanism is set inside the protective box 10.

[0026] like Figure 3 and Figure 4 As shown, the transmission mechanism includes a first transmission gear 11, a transmission rod 12, a second transmission gear 13, and a cam 15. The first transmission gear 11 is installed inside the discharge frame 4 and consists of a fixed column and a gear. Since the first transmission gear 11 is fixed at the center of the discharge frame 4, the discharge frame 4 can drive the first transmission gear 11 to rotate during rotation. The transmission rod 12 is rotatably connected inside the protective box 10. The outer surface of the transmission rod 12 is equipped with a cam 15. The second transmission gear 13 is installed at the outer end of the transmission rod 12, and the first transmission gear 11 meshes with the second transmission gear 13.

[0027] like Figure 4 As shown, the reset mechanism includes a reset spring 16 and a connecting post 19. The reset spring 16 is installed inside the protective box 10, and the connecting post 19 is installed at the inner end of the reset spring 16. A movable block 17 is slidably connected to the inner wall of the top of the protective box 10. A connecting groove is provided on the inner wall of the top of the protective box 10, and the connecting groove is slidably connected to the movable block 17. A movable rod 18 is installed on the lower surface of the movable block 17, and the upper surface of the connecting post 19 is installed at the bottom end of the movable rod 18.

[0028] like Figure 4As shown, the moving mechanism includes a moving frame 20, a moving plate 22, and an auxiliary rod 21. The moving frame 20 is installed on the inner side of the connecting column 19. The moving plate 22 is installed on the inner side of the moving frame 20. The auxiliary rod 21 is rotatably connected to the inside of the moving frame 20. A cleaning brush 14 is installed on the outer side of the protective box 10. The bristles of the cleaning brush 14 are close to the inside of the discharge frame 4, so that the material adhering to the inner wall of the discharge frame 4 is swept off. The auxiliary rod 21 is slidably connected to the inside of the protective box 10. A moving groove is opened on the lower surface of the protective box 10. The moving groove is slidably connected to the auxiliary rod 21. A notch is opened on the upper surface of the fixed frame 7. The auxiliary rod 21 can pass through the notch and extend into the fixed frame 7. The fixed frame 7 and the discharge frame 4 are not directly connected together. An auxiliary frame 23 is installed on the outer surface of the auxiliary rod 21. A disintegrating frame is installed on the outer surface of the auxiliary frame 23.

[0029] like Figure 1 As shown, the outer surface of the feed pipe 6 is connected to the feed frame 24, and the upper surface of the connecting frame 1 is equipped with an upper cover 25.

[0030] In this embodiment, the connecting frame 1 is fixed to the feed inlet of the external elevator by external bolts and nuts, so that the sprocket 3 meshes with the chain at the external hopper; The material is poured into the feed pipe 6 along the feed frame 24. The material enters the fixed frame 7 along the feed pipe 6. After the external hoist runs, the chain drives the sprocket 3 to rotate. The rotation of the sprocket 3 drives the drive shaft 2 to rotate. The drive shaft 2 rotates along the inside of the connecting frame 1. The rotation of the drive shaft 2 drives the discharge frame 4 to rotate. The rotation of the discharge frame 4 drives the first discharge port 5 to rotate. The rotation of the discharge frame 4 drives the first transmission gear 11 to rotate. The rotation of the first transmission gear 11 meshes with the second transmission gear 13 to rotate. The rotation of the second transmission gear 13 drives the transmission rod 12 to rotate. The rotation of the transmission rod 12 drives the cam 15 to rotate. After the cam 15 rotates and contacts the moving plate 22, it pushes the moving plate 22 outward. The outward movement of the moving plate 22 drives the moving frame 20 to move outward. The outward movement of the moving frame 20 drives the auxiliary rod 21 to move outward. The outward movement of the auxiliary rod 21 drives the auxiliary frame 23 to move outward. The outward movement of the auxiliary frame 23 disperses the material in the fixed frame 7. The outward movement of the movable frame 20 causes the connecting column 19 to move outward, the outward movement of the connecting column 19 causes the moving rod 18 to move outward, the outward movement of the moving rod 18 causes the moving block 17 to move outward, the moving block 17 moves outward along the inside of the protective box 10, and the outward movement of the connecting column 19 compresses the return spring 16. When the cam 15 disengages from the moving plate 22, the return spring 16 rebounds, causing the connecting column 19 to move inward. The inward movement of the connecting column 19 causes the moving rod 18 to move inward. The inward movement of the moving rod 18 causes the moving block 17 to move inward. The moving block 17 moves inward along the protective box 10. The inward movement of the connecting column 19 causes the moving frame 20 to move inward. The inward movement of the moving frame 20 causes the auxiliary rod 21 to move inward. The inward movement of the auxiliary rod 21 causes the auxiliary frame 23 to move inward. The auxiliary frame 23 moves inward and resets. This reciprocating movement disperses the accumulated material, preventing material accumulation during the operation of the device and accelerating the movement speed of the material. At the same time, the material in the fixed frame 7 is discharged downwards along the second discharge port 8, and then discharged into the external hopper through the first discharge port 5. The material is then lifted to the processing position by the operation of the external elevator.
