Description

Technical Field

[0001] The utility model relates to the field of loading machines, and particularly relates to an anti-falling protection mechanism for a loading machine. Background Art

[0002] A loading machine is a device for transporting materials. By adding materials into the inner cavity of the hopper of the loading machine, with the operation of the loading machine, the hopper is driven to move upward, transporting the materials to a higher place, which is convenient for adding the materials into the processing equipment.

[0003] When the hopper of the loading machine transports materials, the hopper drives the materials to move upward along the loading machine. After the loading machine is used for a long time, the hopper traction device is prone to wear. Due to the influence of the self-weight of the hopper and the materials in its inner cavity, the traction device is pulled, resulting in the fracture of the traction device, causing the hopper to fall downward, reducing the stability and safety of the loading operation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-falling protection mechanism for a loading machine to solve the problems raised in the above background art.

[0033] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] The present utility model provides a Figures 1-4 fall prevention protection mechanism for a feeding machine as shown in the figure, including a feeding machine main body 1, a hopper 2, a limiting mechanism 3, and a mounting mechanism 4. The hopper 2 is arranged on the feeding machine main body 1. The inner cavity of the hopper 2 is used to accommodate raw materials, and the hopper 2 slides on the feeding machine main body 1. The limiting mechanism 3 is arranged on both sides of the hopper 2. The limiting mechanism 3 is used for a one-way moving structure on both sides of the hopper 2 and preventing the hopper 2 from falling. The hopper {2} is limited by the limiting mechanism 3 to prevent the hopper 2 from falling downward during the rising process, improving the stability of the hopper 2. The mounting mechanism 4 is arranged on the limiting mechanism 3. The mounting mechanism 4 is used to form a movable structure on the limiting mechanism 3 and release the one-way restriction on the limiting mechanism 3.

[0035] The limiting mechanism 3 includes a fixed rod 31, a gear 32, a tooth 33, a fixed tube 34, a ratchet 35 and a limiting block 36. One end of the fixed rod 31 is fixedly connected to one side of the hopper 2. The fixed rod 31 moves together with the hopper 2 and is used to install the gear 32. The gear 32 is rotatably inserted and connected to the other end of the fixed rod 31. The gear 32 is arranged on one side of the feeding machine main body 1 and moves together with the hopper 2 and rolls along a plurality of teeth 33. The teeth 33 are arranged in an equidistant straight line and fixedly connected to one side of the feeding machine main body 1. The teeth 33 are meshed with the bottom of the gear 32. A plurality of teeth 33 are arranged at equal intervals at the bottom of the gear 32. The gear 32 is limited by the meshing action between the teeth 33 and the gear 32. One end of the fixed tube 34 is fixedly connected to one side of the gear 32. The fixed tube 34 is rotatably inserted and connected to the other end of the fixed rod 31. The fixed tube 34 is used to install the ratchet 35. The ratchet 35 and the gear 32 are fixedly connected through the fixed tube 34, so that the ratchet 35 rotates together with the gear 32. The ratchet 35 is fixedly inserted and connected to the fixed tube 34. The ratchet 35 is arranged on one side of the gear 32. The ratchet 35 cooperates with the limiting block 36 to perform one-way rotation of the gear 32. The limiting block 36 is arranged on the top of the ratchet 35. The bottom of the limiting block 36 is inserted between the teeth on the top of the ratchet 35. The bottom of the limiting block 36 is arranged in an inclined plane to ensure the one-way rotation of the ratchet 35. When the hopper 2 drives the fixed rod 31 and the gear 32 to move upward, the gear 32 moves along the teeth 33 and rotates counterclockwise, driving the fixed tube 34 and the ratchet 35 to rotate together. The ratchet 35 presses against the bottom of the limiting block 36 to release the limit of the limiting block 36 on the ratchet 35. When the hopper 2 falls downward, it drives the gear 32 to move downward. The ratchet 35 rotates clockwise. The bottom of the limiting block 36 limits the teeth of the ratchet 35, so that the ratchet 35 and the gear 32 cannot rotate. The gear 32 and the teeth 33 are used to limit and fix the gear 32 and the hopper 2 to prevent the hopper 2 from falling.

[0036] The installation mechanism 4 includes an installation block 41, a hydraulic cylinder 42, a movable rod 43, a connecting rod 44, a tension spring 45 and an installation rod 46. The bottom end of the installation block 41 is fixedly connected to the top of the outer wall of the fixed rod 31. The installation block 41 is arranged at the other end of the fixed pipe 34. The installation block 41 is used for installing the movable rod 43 and the hydraulic cylinder 42. The hydraulic cylinder 42 is fixedly installed on one side of the installation block 41. The hydraulic cylinder 42 is connected to an external power supply through an external switch. By the operation of the hydraulic cylinder 42, the movable rod 43 and the connecting rod 44 are driven to move horizontally to one side, driving the limit block 36 to move onto the ratchet 35 to unidirectionally limit the ratchet 35. One end of the movable rod 43 is rotatably inserted through the top of the limit block 36. The movable rod 43 is arranged on the other side of the installation block 41. The movable rod 43 is used for installing the limit block 36, enabling the limit block 36 to rotate around the limit block 36. One end of the connecting rod 44 is fixedly connected to the other end of the movable rod 43. The other end of the connecting rod 44 is drivingly connected to the output end of the hydraulic cylinder 42. The movable rod 43 and the limit block 36 are driven to move through the connecting rod 44. The tension spring 45 is arranged on one side of the installation block 41. One end of the installation rod 46 is slidably inserted through one end of the tension spring 45. The tension spring 45 is connected to the limit block 36 and the installation block 41 respectively through two installation rods 46. When the ratchet 35 rotates counterclockwise, the ratchet 35 presses against the limit block 36, causing the limit block 36 to rotate around the movable rod 43, stretching and deforming the tension spring 45. And by the elastic action of the tension spring 45, the limit block 36 is pulled to rotate back. At the same time, the limit block 36 is supported by the tension spring 45 to ensure the stability of the limit block 36, facilitating the movement of the limit block 36 between the teeth of the ratchet 35. The other ends of the installation rods 46 are fixedly connected to the outer walls of the limit block 36 and the installation block 41 respectively. When the limit block 36 moves, one end of the installation rod 46 slides at one end of the tension spring 45. The gear 32 and the ratchet 35 move together with the hopper 2. The other end of the connecting rod 44 is slidably inserted through the top of the installation block 41.
