The storage device includes a storage hopper, a guide trough, and a frequency vibration device. The guide trough is located below the storage hopper. One end of the guide trough is connected to the bottom of the storage hopper, and the other end is connected to the lifting device. The frequency vibration device is located at the bottom of the guide trough and is used to drive the material in the guide trough to move towards the lifting device. The lifting device has a discharge port at its upper part and a feeding hopper that reciprocates between a low position and a high position inside the lifting device. When in the low position, the feeding hopper is connected to the guide chute, and when in the high position, the feeding hopper is connected to the discharge port. The feeding hopper includes a mounting base, a hopper body, and a hook-lock assembly. The hopper body is rotatably connected to the mounting base. The hook-lock assembly includes a support base, a support rod, and a connector. The support base is located on one side of the mounting base. The middle part of the support rod is rotatably connected to the support base. The upper part of the support rod has a hook-shaped part. The connector is located near the bottom of the hopper body and has a groove corresponding to the hook-shaped part. When in the low position, the hook-shaped part is inserted into the groove to keep the hopper body and the mounting base relatively stationary.

The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] As attached Figure 1 Appendix Figure 2 The present invention discloses an automatic feeding and lifting machine, which includes a storage device 1 and a lifting device 2. The storage device 1 includes a storage hopper 11, a guide trough 12 and a frequency vibration device 13. The storage hopper 11 is used to temporarily store the material to be lifted. The guide trough 12 is installed below the storage hopper 11. One end of the guide trough 12 is connected to the bottom of the storage hopper 11, and the other end is connected to the lifting device 2. The frequency vibration device 13 is installed at the bottom of the guide trough 12 and is used to vibrate and drive the material in the guide trough 12 to move towards the lifting device 2.

[0018] The upper part of the lifting device 2 has a discharge port 21. Inside the lifting device 2 is a feeding hopper 3 that reciprocates between a low position and a high position. When in the low position, the feeding hopper 3 is connected to the guide chute 12, and the material in the guide chute 12 falls into the feeding hopper 3. When in the high position, the feeding hopper 3 is connected to the discharge port 21, discharging the material from the discharge port 21. (See attached diagram) Figure 5-7 As shown, the hopper 3 includes a mounting base 31, a hopper body 32, and a hook-lock assembly. The hopper body 32 is rotatably connected to the mounting base 31 around a pivot 39. The hook-lock assembly includes a support base 33, a support rod 34, and a connector 35. The support base 33 is installed on one side of the mounting base 31. The middle part of the support rod 34 is rotatably connected to the support base 33. A hook-shaped part 341 is formed on the upper part of the support rod 34. The connector 35 is installed near the bottom of the hopper body 32. A groove 351 corresponding to the hook-shaped part 341 is machined on the connector 35. When in a low position, the hook-shaped part 341 is inserted into the groove 351 to keep the hopper body 32 and the mounting base 31 relatively stationary, preventing the hopper body 32 from tipping over and causing the material to scatter. When in a high position, the hook-shaped part 341 is dislodged from the groove 351, allowing the hopper body 32 to rotate around the mounting base 31 and pour material towards the discharge port 21.

[0019] A compression spring 36, connected to the support base 33, is installed on the lower part of the support rod 34 near the mounting base 31. When no external force is applied, the compression spring 36 presses the lower part of the support rod 34, causing its hook-shaped part 341 to insert into the groove 351. (See attached image) Figure 7 As shown, a guide bar 4 is installed on the inner wall of the lifting device 2 near the high position. The bottom end of the guide bar 4 gradually tapers towards the inner wall. A roller 37 is installed on the lower part of the support rod 34 away from the mounting base 31. When the feeding hopper 3 moves from the low position to the high position, the roller 37 rolls along the guide bar 4. The lower part of the support rod 34 is squeezed by the guide bar 4, causing the hook-shaped part 341 of the upper part of the support rod 34 to disengage from the groove 351. (See attached diagram) Figure 6 As shown, a guide wheel 5 is installed on the inner wall of the lifting device 2 near the high position, and a guide groove 38 is installed on the side of the hopper body 32. When the hook-shaped part 341 disengages from the groove 351 and the upper hopper 3 moves upward, the fixed guide wheel 5 rolls along the guide groove 38, causing the hopper body 32 to rotate around the mounting base 31 under traction. With the cooperation of the hook-lock assembly and guide bar 4, guide wheel 5 and guide groove 38, the upper hopper 3 moves in an orderly manner, enabling the hopper body 32 to achieve the function of controllably dumping materials.

[0020] A cylinder 14 is installed at one end of the feed chute 12 near the lifting device 2. A baffle 15 is installed at the output end of the cylinder 14 to block the feed chute 12 after the feed hopper 3 leaves, preventing material from scattering. To prevent small materials such as screws and nuts from getting stuck at the outlet of the feed chute 12, the baffle 15 is lowered below the feed chute 12 by the cylinder 14 before rising again, preventing material from getting caught on the edge of the feed chute 12 and causing damage to the device.

[0021] A control box 6 is installed on the outside of the lifting device 2. The control box 6 has a touch screen 61 and buttons 62. Traditional elevators do not have touch screens, and equipment malfunctions rely entirely on guesswork, requiring on-site maintenance personnel to constantly troubleshoot various causes, making it difficult to quickly identify abnormalities. The touch screen 61 in this invention displays abnormal conditions with clear prompts, facilitating later maintenance. The elevator can automatically control feeding, or it can be manually controlled by using some buttons 62. For example, if the amount of material lifted at one time is small, feeding can be operated via buttons 62, achieving manual and automatic closed-loop control.

[0022] A motor 7 is installed on the upper part of the lifting device 2, as shown in the attached diagram. Figure 2 As shown, a drive sprocket 8 is installed at the output end of the motor 7, and a driven sprocket 9 is installed at the lower part of the lifting device 2. A chain 10 is fitted onto the drive sprocket 8 and the driven sprocket 9. One side of the chain 10 is connected to the mounting base 31. The motor 7 drives the feeding hopper 3 to rise or fall by rotating forward and backward. A guide rail 20 is installed on one side of the lifting device 2. A slider that is slidably connected to the guide rail 20 is connected to the guide rail 20. The slider is connected to the mounting base 31, making the operation of the feeding hopper 3 more stable.

[0023] The discharge port 21 includes a channel extending obliquely downward. At the end of the channel, a sensor 30 is installed to sense the height of the material to control whether the elevator continues to operate. When the amount of material at the discharge port 21 reaches a set value, the sensor 30 sends a signal to stop the elevator.

[0024] In operation, the material of this automatic feeding elevator enters the guide trough 12 from the storage hopper 11. Under the vibration of the frequency vibration device 13, the material enters the feeding hopper 3 at the lower position along the guide trough 12. The motor 7 drives the feeding hopper 3 connected to the chain 10 to be lifted upward. During this process, the hopper body 32 is locked to the mounting base 31 by the hook lock assembly to prevent the hopper body 32 from tipping over and the material from scattering. When the feeding hopper 3 runs to the high position, the roller 37 of the hook lock assembly rolls along the guide bar 4, the lower part of the support rod 34 is pressed, and the hook-shaped part 341 of the upper part of the support rod 34 disengages from the groove 351, so that the hopper body 32 is unlocked from the mounting base 31. The hopper body 32 rotates to pour the material out from the discharge port 21, thus safely and reliably realizing the automatic feeding function.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
