Description

Technical Field

[0001] This invention belongs to the field of lifting equipment technology, and in particular relates to an anti-accumulation lifting unloading device. Background Technology

[0002] Material handling refers to activities conducted within the same location, primarily aimed at changing the storage state and spatial position of materials. With the development of automation and intelligent technologies, lifting and unloading devices have been proposed, integrating advanced control systems such as sensors, automatic control platforms, and human-machine interfaces. This integration not only further improves operational convenience and safety but also enhances the intelligence level of the device.

[0003] Existing lifting-type feeding devices often have issues with materials that tend to stick to the inside of the hopper, requiring manual cleaning and affecting the hopper's usability. Therefore, a lifting-type feeding device to prevent material accumulation is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-accumulation lifting discharge device. After the material tank finishes discharging, it can vibrate the tank to prevent the raw material inside from adhering to the inner wall, making the tank easy to reuse. At the same time, the torsion spring in the energy-saving mechanism generates a certain pulling force on the tank, thereby reducing the energy consumption of the motor. Furthermore, when the tank is falling, the pressure plate and safety block work together to brake it, improving the safety of use and solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A lifting-type unloading device for preventing material accumulation includes:

[0007] The base has a guide box fixedly connected to its surface, a slide plate slidably connected to one side of the guide box, a material tank installed on one side of the slide plate, and an impact mechanism for impacting the material tank on one side of the material tank.

[0008] The impact mechanism includes a guide rail, which is fixed to the top of the slide plate. A slider is slidably connected inside the guide rail. A second threaded rod is threadedly connected to the top of the slider. The second threaded rod rotates through the top of the guide rail. Impact components are provided on both sides of the slider.

[0009] The impact assembly includes a rotating rod, a fixed block, and multiple levers. The rotating rod is rotatably connected to one side of the slider, and a rotating frame is fixedly connected to one end of the rotating rod. The fixed block is fixedly connected to one side of the material tank and works in conjunction with the rotating frame. A second torsion spring is fixedly connected between the slider and the rotating rod. A lever is rotatably connected to the circumference of the rotating rod, and a semi-annular extension sleeve is fixedly connected to one side of the lever. A positioning block that works in conjunction with the extension sleeve is fixedly connected to the circumference of the rotating rod. A first torsion spring is fixedly connected between the lever and the rotating rod. Multiple levers are fixed to the outer wall of one side of the guide box and work in conjunction with the lever. By installing the impact mechanism on one side of the material tank, during the reset process after the material tank has finished discharging material, the rotating frame and the fixed block work together to impact the material tank, causing it to vibrate. This prevents the raw material inside the material tank from adhering to the inner wall, facilitating the reuse of the material tank.

[0010] Furthermore, the material tank includes a hopper cover, an adjusting cylinder, and a hopper seat. The adjusting cylinder is located between the hopper cover and the hopper seat, and its two ends respectively abut against the hopper cover and the hopper seat. The fixing block is fixed to the circumference of the hopper seat.

[0011] Furthermore, a first connecting frame is fixed to the circumference of the hopper cover by bolts, a base frame is provided at the bottom of the hopper seat, the base frame is fixed to the slide plate, a fixing cylinder is fixedly connected to the surface of the base frame, a sleeve is fixedly connected to one side of the first connecting frame, and a first threaded rod is rotatably connected to the top of the sleeve. The first threaded rod is threaded through the fixing cylinder. Rotating the first threaded rod can separate the hopper cover and the hopper seat, thereby making it convenient for the staff to replace different adjusting cylinders.

[0012] Furthermore, two electric push rods are fixedly connected to the surface of the base frame, and a second connecting frame is fixedly connected between one end of the output shaft of the two electric push rods. The hopper seat is fixed to the top of the second connecting frame.

[0013] Furthermore, the bottom of the base frame is fixedly connected to two hydraulic rods and multiple rollers.

[0014] Furthermore, a motor is fixedly connected to one side of the guide box, and a third threaded rod is rotatably connected to the bottom inner wall of the guide box. The third threaded rod is threaded through the slide plate, and the top of the third threaded rod is rotatably connected through the guide box and fixedly connected to one end of the motor output shaft with a gear, which meshes with the gear.

[0015] Furthermore, an energy-saving mechanism is provided on one side of the guide box. The energy-saving mechanism includes a buffer shaft and two guide wheels. The buffer shaft is rotatably connected to the surface of the base. Two take-up wheels are fixedly connected to the circumference of the buffer shaft. A third torsion spring is fixedly connected to one side of each of the two take-up wheels and the base. The two guide wheels are rotatably connected to both sides of the guide box. A pull rope is wound inside each of the take-up wheels. The two pull ropes pass around the two guide wheels and are fixed to the first connecting frame. By installing the energy-saving mechanism on one side of the guide box, the torsion springs in the energy-saving mechanism can generate a certain pulling force on the material tank during the process of the material tank moving up and down, thereby reducing the energy consumption of the motor.

[0016] Furthermore, the circumference of the buffer shaft is also provided with an anti-fall mechanism, which includes a safety disc and a safety block. The safety block is fixed to one side of the guide box, and the safety disc is fixed to the circumference of the buffer shaft. The safety disc contains multiple anti-fall components, each including a limiting rod and a rotating shaft. Both the limiting rod and the rotating shaft are rotatably connected inside the safety disc. An inclined pressure plate is fixedly connected to the circumference of the rotating shaft. The two ends of the rotating shaft pass through both sides of the safety disc and are fixedly connected to the safety disc with a fourth torsion spring. By installing the mounting disc on the buffer shaft, when the material tank falls, the pull rope accelerates the rotation of the mounting disc, thereby using centrifugal force to throw the pressure plate out and cooperate with the safety block for braking, improving the safety of use.

[0017] The embodiments of the present invention have the following beneficial effects:

[0018] In this invention, by installing an impact mechanism on one side of the material tank, during the reset process after the material tank has finished discharging, the rotating frame and the fixed block can collide with the material tank to cause it to vibrate, thereby preventing the raw materials inside the material tank from adhering to the inner wall and facilitating the reuse of the material tank.

[0019] In this invention, by installing an energy-saving mechanism on one side of the guide box, the torsion spring in the energy-saving mechanism can generate a certain pulling force on the material tank during the process of the material tank going up and down, thereby reducing the energy consumption of the motor.

[0020] In this invention, by installing a mounting plate on the buffer shaft, the installation plate can be accelerated to rotate during the drop of the material tank due to the pull rope. This, in turn, uses centrifugal force to throw the pressure plate out and works in conjunction with the safety block to brake, thereby improving the safety of use.

[0021] In this invention, after the material tank finishes discharging, during the resetting process, the rotating frame and the fixed block can collide with the material tank, causing it to vibrate. This prevents the raw material inside the tank from adhering to the inner wall, facilitating the reuse of the tank. At the same time, the torsion spring in the energy-saving mechanism generates a certain pulling force on the material tank, thereby reducing the energy consumption of the motor. Furthermore, when the material tank falls, the pull rope accelerates the rotation of the mounting plate, using centrifugal force to throw the pressure plate out and cooperate with the safety block for braking, improving the safety of use.

[0022] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0033] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0034] Example 1

[0035] Please see Figures 1-6 As shown, this embodiment provides an anti-accumulation lifting feeding device, including: a base 1, the surface of the base 1 is provided with a plurality of through mounting holes, a guide box 2 is fixedly connected to the surface of the base 1, a reinforcing triangular block is welded between the base 1 and the guide box 2, a sliding plate 3 is slidably connected to one side of the guide box 2, a material tank 4 is installed on one side of the sliding plate 3, and an impact mechanism for impacting the material tank 4 is provided on one side of the material tank 4.

[0036] The impact mechanism includes a guide rail 20, which is fixed to the top of the slide plate 3. A slider 21 is slidably connected inside the guide rail 20. A second threaded rod 28 is threadedly connected to the top of the slider 21. The second threaded rod 28 rotates through the top of the guide rail 20. Rotating the second threaded rod 28 can adjust the height of the slider 21 to adapt to the material tank 4. Impact components are provided on both sides of the slider 21.

[0037] The impact assembly includes a rotating rod 22, a fixed block 19, and multiple levers 241. The rotating rod 22 is rotatably connected to one side of the slider 21, and a rotating frame 18 is fixedly connected to one end of the rotating rod 22. The fixed block 19 is fixedly connected to one side of the material tank 4 and works in conjunction with the rotating frame 18. A second torsion spring 25 is fixedly connected between the slider 21 and the rotating rod 22. A lever 24 is rotatably connected to the circumference of the rotating rod 22. A semi-annular extension sleeve 26 is fixedly connected to one side of the lever 24. A positioning block 27 that works in conjunction with the extension sleeve 26 is fixedly connected to the circumference of the rotating rod 22. A first torsion spring 23 is fixedly connected between the 4 and the rotating rod 22. Multiple levers 241 are fixed on one side of the outer wall of the guide box 2 and work with the lever 24. When the slide plate 3 descends, the lever 24 contacts the lever 241 again. At this time, the lever 24 drives the rotating rod 22 to rotate under the action of the positioning block 27. The rotating rod 22 drives the rotating frame 18 to rotate downward. After disengaging, the rotating rod 22 and the rotating frame 18 reset under the action of the second torsion spring 25. The rotating frame 18 impacts the fixed block 19, thereby causing the material tank 4 to vibrate and preventing raw materials from adhering to the inner wall of the material tank 4.

[0038] Example 2

[0039] Improvements based on Example 1: See Appendix Figures 1-6 ,

[0040] Reference Figure 2 The material tank 4 includes a hopper cover 7, an adjusting cylinder 9, and a hopper seat 10. The adjusting cylinder 9 is located between the hopper cover 7 and the hopper seat 10, and its two ends abut against the hopper cover 7 and the hopper seat 10 respectively. The fixing block 19 is fixed on the circumference of the hopper seat 10. Separating the hopper cover 7 and the hopper seat 10 allows the adjusting cylinder 9 to be replaced, which facilitates changing the volume inside the material tank 4 and improves the flexibility of use.

[0041] Reference Figure 2 The circumference of the hopper cover 7 is fixed with a first connecting frame 8 by bolts. The bottom of the hopper seat 10 is provided with a base frame 12, which is fixed to the slide plate 3. A fixing cylinder 14 is fixedly connected to the surface of the base frame 12. A sleeve 141 is fixedly connected to one side of the first connecting frame 8. A first threaded rod 15 is rotatably connected to the top of the sleeve 141. The first threaded rod 15 is threaded through the fixing cylinder 14. Rotating the first threaded rod 15 can separate the hopper cover 7 and the hopper seat 10, thereby making it convenient for the staff to replace different adjusting cylinders 9.

[0042] Reference Figure 2 Two electric push rods 13 are fixedly connected to the surface of the base frame 12. A second connecting frame 11 is fixedly connected between one end of the output shaft of the two electric push rods 13. The hopper seat 10 is fixed on the top of the second connecting frame 11. Activating the electric push rods 13 can increase the sealing and stability of the clamping of the adjusting cylinder 9, making it safe to use.

[0043] Reference Figure 2 The bottom of the base frame 12 is fixedly connected to two hydraulic rods 17 and multiple rollers 16. The hydraulic rods 17 increase the stability of the material tank 4 when it lands, and the rollers 16 make it easy for the material tank 4 to be disassembled and moved.

[0044] Reference Figure 6 A motor 38 is fixedly connected to one side of the guide box 2. A third threaded rod 39 is rotatably connected to the bottom inner wall of the guide box 2. The third threaded rod 39 is threaded through the slide plate 3. The top of the third threaded rod 39 is rotatably connected through the guide box 2 and a gear 40 is fixedly connected to one end of the output shaft of the motor 38. The two gears 40 mesh, and the motor 38 drives the third threaded rod 39 to rotate through the gears 40, thereby driving the slide plate 3 to move, thus realizing the lifting and lowering of the material tank 4.

[0045] Reference Figure 4 An energy-saving mechanism is also provided on one side of the guide box 2. The energy-saving mechanism includes a buffer shaft 29 and two guide wheels 6. The buffer shaft 29 is rotatably connected to the surface of the base 1. Two take-up wheels 30 are fixedly connected to the circumference of the buffer shaft 29. A third torsion spring 31 is fixedly connected to one side of each of the two take-up wheels 30 and the base 1. The two guide wheels 6 are rotatably connected to the two sides of the guide box 2 respectively. A pull rope 5 is wound inside each of the take-up wheels 30. The two pull ropes 5 pass around the two guide wheels 6 respectively and are fixed to the first connecting frame 8. During the process of the material tank 4 rising, the third torsion spring 31 applies force to the take-up wheel 30, which in turn pulls the pull rope 5 through the take-up wheel 30. The pull rope 5 pulls the material tank 4, thereby reducing the energy consumption of the motor 38 and achieving the effect of energy saving. A protective cover is also provided on the base 1 to protect the third torsion spring 31.

[0046] Reference Figure 4 and Figure 5The buffer shaft 29 is also equipped with an anti-fall mechanism, which includes a safety disc 32 and a safety block 37. The safety block 37 is fixed to one side of the guide box 2, and the safety disc 32 is fixed to the circumference of the buffer shaft 29. The safety disc 32 is equipped with multiple anti-fall components, including a limit rod 33 and a rotating shaft 34. Both the limit rod 33 and the rotating shaft 34 are rotatably connected inside the safety disc 32. The circumference of the rotating shaft 34 is fixedly connected to an inclined pressure plate 36. The two ends of the rotating shaft 34 pass through both sides of the safety disc 32 and are fixedly connected to the safety disc 32 with a fourth torsion spring 35. When the material tank 4 falls accidentally, the pull rope 5 pulls the take-up wheel 30 and the buffer shaft 29 to rotate quickly. The buffer shaft 29 drives the safety disc 32 to rotate quickly. Under the action of centrifugal force, the pressure plate 36 rotates. Then the pressure plate 36 abuts against the safety block 37, and under the support of the limit rod 33, it prevents the material tank 4 from falling continuously, thus improving the safety of use.

[0047] The usage process and working principle of the technical solution of this invention are as follows:

[0048] In use, the motor 38 is started, and the motor 38 drives the third threaded rod 39 to rotate through the gear 40, which in turn drives the slide plate 3 to move, thereby realizing the lifting and lowering of the material tank 4. When the material tank 4 is lifted, the material is discharged through the discharge valve set at the bottom.

[0049] During the process of the material tank 4 rising, the third torsion spring 31 applies force to the take-up reel 30, which in turn pulls the pull rope 5 through the take-up reel 30. The pull rope 5 pulls the material tank 4, thereby reducing the energy consumption of the motor 38 and achieving the effect of energy saving.

[0050] When the material tank 4 falls accidentally, the pull rope 5 pulls the take-up wheel 30 and the buffer shaft 29 to rotate quickly. The buffer shaft 29 drives the safety disc 32 to rotate quickly. Under the action of centrifugal force, the pressure plate 36 rotates. Then the pressure plate 36 abuts against the safety block 37, and under the support of the limit rod 33, it prevents the material tank 4 from falling continuously, thus improving the safety of use.

[0051] During the upward movement of the slide plate 3, the slider 21, the rotating rod 22, and the lever 24 are also driven to rise. During the upward movement of the lever 24, it comes into contact with the lever 241, which causes the lever 24 to rotate. After the contact is broken, the lever 24 returns to its original position under the action of the first torsion spring 23. Then, when the slide plate 3 descends, the lever 24 comes into contact with the lever 241 again. At this time, the lever 24 drives the rotating rod 22 to rotate under the action of the positioning block 27. The rotating rod 22 drives the rotating frame 18 to rotate downward. After the contact is broken, the rotating rod 22 and the rotating frame 18 return to their original position under the action of the second torsion spring 25. The rotating frame 18 impacts the fixed block 19, which causes the material tank 4 to vibrate, preventing raw materials from adhering to the inner wall of the material tank 4 and making it convenient for reuse.

[0052] Rotating the first threaded rod 15 allows the hopper cover 7 and the hopper seat 10 to separate, thereby enabling the replacement of different adjusting cylinders 9 to change the internal volume of the material tank 4 and improve the flexibility of use. Activating the electric push rod 13 can increase the sealing and stability of the adjusting cylinder 9, ensuring safe use.
