Description

Technical Field

[0001] This utility model relates to the technical field of hopper blocking structures, specifically a hopper blocking device for a chain conveyor. Background Technology

[0002] Chain conveyors are industrial equipment that use chains as the core transmission element to transport materials. Types include double-speed chain conveyors, top-plate chain conveyors, and plastic-steel chain conveyors. This equipment uses special chains (such as accumulation chains) to achieve large-scale transportation of materials such as pallets and large turnover boxes, and is widely used in production lines in industries such as electronics, food, and logistics.

[0003] When a chain conveyor is in use, it supports and transports hoppers. After the hoppers are transported to the end of the chain conveyor, they are prone to falling off the chain conveyor due to inertia or malfunction. Therefore, it is necessary to block the hoppers during actual use to prevent them from falling off.

[0004] Traditional hopper blocking structures mostly use cylinders to drive the blocking blocks for structural blocking. This technology requires program control design of the cylinders, resulting in high costs and poor economic efficiency in actual use. Therefore, this utility model proposes a hopper blocking device for chain conveyors. Utility Model Content

[0005] The purpose of this invention is to provide a hopper blocking device for chain conveyors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chain conveyor hopper blocking device, comprising a chain conveyor body, a stop block rotatably mounted on the top outer wall of the chain conveyor body via a rotating shaft, a roller mounted on the outer surface of one end of the stop block, a trolley track provided at the tail end of the chain conveyor body, a receiving trolley provided on the trolley track, and a lever fixedly mounted on the outer wall of the receiving trolley near the chain conveyor body.

[0007] Preferably, the stop block adopts a rectangular structure design.

[0008] Preferably, the chain conveyor body is equipped with a hopper.

[0009] Preferably, the lever is configured with a trapezoidal structure.

[0010] Preferably, the rotating shaft is positioned in the middle of the stop block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model can block the hopper by setting a stop. When the receiving trolley has not reached the receiving position, the stop in the vertical blocking state can effectively block the hopper, thereby effectively preventing the hopper from falling due to misoperation or inertia when it is conveyed to the tail end of the chain conveyor body. It has a good hopper blocking effect and ensures the conveying safety of the chain conveyor body.

[0013] Simultaneously, as the receiving trolley reaches the receiving position, the lever, which moves synchronously with the receiving trolley, can guide the vertical stop to a horizontal position through its inclined guide surface. This releases the stop from blocking material, allowing the hopper to smoothly enter the receiving trolley. In actual use, the lever and stop work together to automatically release the obstruction when the trolley enters, demonstrating good structural coordination. Furthermore, the lever and stop are guided by rollers, which effectively reduces friction, protects the contact surface, and makes the rotation process smoother, thus improving the structural performance.

[0014] The blocking device of this utility model can freely switch between blocking and passing states by means of the mutual cooperation between the structures and the basic physical principles. When the receiving trolley has not arrived, it is vertically upright by gravity, which is the blocking state. After the receiving trolley arrives, the blocking block is switched to the horizontal passing state by means of the use of the lever. This has a good structural cooperation effect. In actual use, this structure does not require manual program control settings, which can effectively reduce the cost of the blocking function. The overall device has good structural economy, is more practical, and has a simpler structural principle, making it suitable for implementation. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components.

[0022] Please see Figure 1-3 This utility model provides an embodiment of a chain conveyor hopper blocking device, comprising a chain conveyor body 1. A stop block 3 is rotatably mounted on the top outer wall of the chain conveyor body 1 via a rotating shaft 2. The stop block 3 has a rectangular structure design. The rotating shaft 2 is located in the middle of the stop block 3. A roller 4 is mounted on the outer surface of one end of the stop block 3. Due to the weight-adding effect of the roller 4, the weight of one end of the stop block 3 is greater than the weight of the other end. Under normal conditions, one end of the roller 4 falls due to gravity, causing the stop block 3 to be in a vertical state. For details of the vertical state, please refer to the appendix of the instruction manual. Figure 3 As shown, the vertical stop 3 can play a certain blocking role.

[0023] In this embodiment, a trolley track 5 is provided at the tail end of the chain conveyor body 1, and a receiving trolley 6 is provided on the trolley track 5. A pawl 7 is fixedly installed on the outer wall of the receiving trolley 6 near the chain conveyor body 1. The pawl 7 adopts a trapezoidal structure, that is, the two sides of the pawl 7 are inclined surfaces and the middle is a horizontal surface.

[0024] In this structural design, when the receiving trolley 6 reaches the tail end of the chain conveyor body 1 via the trolley track 5, during the movement of the receiving trolley 6 towards the tail end, the top of its lever 7 can contact the roller 4 of the stop block 3. Through the side guide slope of the lever 7, the stop block 3 can be lifted during the movement, causing the stop block 3 in the vertical state to rotate 90° clockwise to a horizontal state, completing the conversion of the stop block 3 from a vertical state to a horizontal state. The stop block 3 in the horizontal state no longer has an obstructing effect, thus ensuring normal passage. The horizontal contact state between the stop block 3 and the lever 7 is shown in the attached instruction manual. Figure 2 As shown.

[0025] In this embodiment, a hopper 8 is provided on the chain conveyor body 1 to ensure normal material conveying operation.

[0026] Working principle: When the chain conveyor hopper blocking device of this utility model is in use, the hopper 8 on the chain conveyor body 1 can be loaded with materials, and the hopper 8 can be conveyed through the chain conveyor body 1.

[0027] This invention features a rotatably mounted stop block 3 at the tail end of the chain conveyor body 1. Because a roller 4 is mounted on the outer surface of one end of the stop block 3, the weight of one end of the stop block 3 is greater than the weight of the other end due to the weight gain effect of the roller 4. Under normal conditions, the heavier end of the roller 4 falls, causing the stop block 3 to be in a vertical position. For details on the vertical position, please refer to the appendix to the instruction manual. Figure 3 As shown, the vertical stop 3 can block the hopper 8 to a certain extent, preventing the hopper 8 from falling due to misoperation or inertia when it is conveyed to the tail end of the chain conveyor body 1. It has a good hopper blocking effect and ensures the conveying safety of the chain conveyor body 1.

[0028] When the receiving trolley 6 receives material, it travels along the trolley track 5 to the tail end of the chain conveyor body 1. During this movement, the top of the receiving trolley 6, the lever 7, rolls against the roller 4 of the stop block 3. Guided by the side guide slope of the lever 7, the stop block 3 is lifted during the movement, causing it to rotate 90° clockwise from its vertical position to a horizontal position. This completes the transition of the stop block 3 from a vertical to a horizontal position. In this horizontal position, the stop block 3 no longer obstructs the hopper 8, ensuring the normal passage of the hopper 9. The chain conveyor body 1 then transfers the hopper 8 to the receiving trolley 6, which then transports it to the next area, completing the material receiving and transfer process. The horizontal contact state between the stop block 3 and the lever 7 is described in the attached instruction manual. Figure 2 As shown;

[0029] After the receiving trolley 6 leaves, the stop block 3 loses the effect of the paddle 7. It rotates counterclockwise again to the vertical blocking state due to gravity, thus ensuring the normal blocking effect and having the practical characteristic of self-resetting.

[0030] Based on the above structure, the present invention can block the hopper 8 by setting the stop 3. When the receiving trolley 6 has not reached the receiving position, the stop 3 in the vertical blocking state can effectively block the hopper 8, thereby effectively preventing the hopper 8 from falling due to misoperation or inertia when it is conveyed to the tail end of the chain conveyor body 1. It has a good hopper blocking effect and ensures the conveying safety of the chain conveyor body 1.

[0031] Simultaneously, as the receiving trolley 6 reaches the receiving position, the lever 7, which moves synchronously with the receiving trolley 6, can guide the vertical stop 3 to a horizontal state through its inclined guide, thereby releasing the material blocking state of the stop 3 and allowing the hopper 8 to smoothly enter the receiving trolley 6. In actual use, the lever 7 and the stop 3 work together to automatically release the obstruction state when the trolley enters, resulting in a good structural cooperation effect. Furthermore, the lever 7 and the stop 3 are guided by rollers 4, which effectively reduces friction, protects the contact surface, makes the rotation process smoother, and improves the structural performance.

[0032] The blocking device of this utility model can freely switch between blocking and passing states by means of the mutual cooperation between the structures and the basic physical principles. When the receiving trolley 6 has not arrived, it is vertically upright by gravity and is in the blocking state. After the receiving trolley 6 arrives, the blocking block 3 is switched to the horizontal passing state by means of the use of the lever 7. This has a good structural cooperation effect. In actual use, this structure does not require manual program control settings, which can effectively reduce the cost of the blocking function. The overall device has good structural economy, is more practical, and has a simpler structural principle, making it suitable for implementation.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
