Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:
[0016] Please see Figure 1 As shown, this utility model provides a guide trough for a belt conveyor, including a trough body 1. A top fixing frame 2 is installed on the top of the trough body 1 by fastening bolts 19. A movable slider 4 is slidably installed on the top of the top fixing frame 2. An electric cylinder 5 is installed on the top of the movable slider 4. The output end of the electric cylinder 5 extends through to the bottom of the movable slider 4 and is installed with a lifting plate 6. Crushing rods 7 are installed at equal intervals at the bottom of the lifting plate 6. Support springs 8 are installed on both the front and rear sides of the right end of the inner cavity of the trough body 1. A guide plate 9 is installed on the inner end of the support spring 8. A fixed baffle 10 is rotatably installed on the left end of the guide plate 9. The left end of the fixed baffle 10 is connected to the inner wall of the trough body 1. A positioning insertion hole 18 is symmetrically opened on the top of the top fixing frame 2. A plug rod 16 is vertically snapped into the inside of the positioning insertion hole 18. A limit spring 17 is sleeved on the upper end of the plug rod 16. The lower end of the limit spring 17 is connected to the top of the movable slider 4.
[0017] This technical solution includes an electric cylinder 5, a lifting plate 6, and a crushing rod 7. The electric cylinder 5 can drive the lifting plate 6 and the crushing rod 7 to move up and down, which can crush material lumps in the trough 1, effectively preventing material lumps from clogging the guide trough and ensuring normal material conveying. The movable slider 4 can slide in the movable groove 3 of the top fixed frame 2, which facilitates the adjustment of the lateral position of the crushing rod 7. Combined with the positioning hole 18, the plug rod 16, and the limit spring 17, the movable slider 4 can be fixed in the required position, improving the flexibility of the crushing structure. The crushing position can be adjusted according to the actual material conditions to meet the needs of different working conditions. Example 2:
[0018] Based on Embodiment 1, this utility model is as follows: Figure 4 As shown, a positioning frame 11 is installed on the outer ring of the top of the movable slider 4, and the upper end of the plug rod 16 passes through the positioning frame 11 and extends to the top where a pull frame 14 is installed.
[0019] Adopting such Figure 1 The technical solution shown provides a stable installation and guiding foundation for the plug-in rod 16, ensuring that the plug-in rod 16 can accurately achieve vertical movement and avoid deviation or shaking during movement, thus ensuring the accuracy of plug-in positioning. The upper end of the plug-in rod 16 passes through the positioning frame 11 and is then installed with a pull frame 14, allowing the operator to easily move the plug-in rod 16 by manipulating the pull frame 14 without directly contacting the plug-in rod 16, thereby improving the convenience of operation.
[0020] Secondly, in the technical solution, the top fixed frame 2 has a moving groove 3 on both the front and rear sides of the top, and the lower end of the moving slider 4 is engaged in the inside of the moving groove 3 and is installed laterally; the top of the positioning frame 11 has guide rods 12 installed at both the front and rear ends, and the upper end of the guide rods 12 passes through the pulling frame 14 and extends to the top to install the limiting plate 13.
[0021] Its adoption is as follows Figure 1 The technical solution shown provides a precise lateral sliding track for the movable slider 4 in the movable groove 3, which prevents it from deviating, tilting or shaking during the sliding process, and ensures that the movable slider 4 moves stably along the set track, thereby ensuring that the position adjustment of components such as the crushing rod 7 is accurate and reliable. The upper end of the guide rod 12 passes through the pull frame 14 and is equipped with a limiting plate 13, which provides precise guidance for the vertical movement of the pull frame 14. This effectively prevents the pull frame 14 from tilting or twisting when moving up and down, ensuring that the pull frame 14 can drive the plug rod 16 to move up and down stably and vertically. This also ensures the precise docking or separation of the plug rod 16 and the positioning hole 18. The limiting plate 13 can effectively restrict the upward position of the pull frame 14, preventing the pull frame 14 from falling off the guide rod 12 due to improper operation, thus improving the safety and stability of the structure. Example 3:
[0022] This utility model is as follows Figures 1-4 As shown, a handle 15 is installed on the top of the pull frame 14, and through slots for the guide rod 12 to move are opened in the interior of both the front and rear ends of the pull frame 14; sliding slots are opened in the interior of both the front and rear ends of the movable slider 4, and the lower end of the plug rod 16 passes through the sliding slot and connects to the interior of the positioning plug hole 18.
[0023] With the above technical solution, the through slots opened inside the front and rear ends of the pulling frame 14 for the guide vertical rod 12 to move are precisely matched with the guide vertical rod 12. This ensures that the guide vertical rod 12 guides the pulling frame 14 and provides sufficient space for the vertical movement of the pulling frame 14, avoiding jamming or interference between the two and ensuring that the pulling frame 14 drives the plug-in rod 16 to move smoothly. The sliding grooves inside the front and rear ends of the movable slider 4 provide a reasonable channel for the insertion rod 16 to pass through and move, so that the insertion rod 16 can pass smoothly through the movable slider 4 and connect with the positioning insertion hole 18 of the top fixing frame 2 to fix the movable slider 4. This structural design ensures the rationality of the installation and movement of the insertion rod 16, avoids structural conflicts caused by space constraints, and allows the positioning function of the insertion rod 16 to be stably performed.
[0024] The working principle of this utility model is as follows: When there are lumps in the material, the electric cylinder 5 is started, and its output end drives the lifting plate 6 to move up and down. The crushing rod 7 at the bottom of the lifting plate 6 moves up and down to repeatedly crush the material lumps in the trough 1 to avoid the lumps blocking the guide trough. During the material conveying process, the guide plate 9 in the trough 1 is kept stable under the action of the support spring 8. It works with the fixed baffle 10 to guide the material, so that the material can flow smoothly in the trough 1 along the set path and reduce material residue. When the lateral position of the crushing rod 7 needs to be adjusted, the operator pulls the handle 15 to move the pulling frame 14 upward. Under the guidance of the guide rod 12, the pulling frame 14 moves upward along the through groove, and at the same time moves the plug rod 16 upward. The plug rod 16 compresses the limiting spring 17 and is pulled out from the positioning hole 18. At this time, the movable slider 4 is released from the fixed state. The operator can push the movable slider 4 to slide laterally in the moving groove 3 of the top fixed frame 2 to the desired position. After reaching the target position, the operator releases the handle 15, the limiting spring 17 returns to its original position, and pushes the plug rod 16 downward. The plug rod 16 passes through the sliding groove of the movable slider 4 and inserts into the corresponding positioning hole 18, thereby fixing the movable slider 4. After fixing, the electric cylinder 5 drives the crushing rod 7 to work again to realize material crushing operations at different positions.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
