AI Technical Summary
When using an inclined belt conveyor to transport spherical or granular materials, the materials are prone to rolling out along the tail of the machine, making it difficult to clean up the accumulated material and posing a safety hazard. In addition, the fully enclosed design increases the difficulty of cleaning and the risk of mechanical injury.
A device for preventing material spillage from a belt conveyor has been designed, including a frame, a moving trolley, a baffle, and a limiting mechanism. By setting a through trough and a moving trolley at the bottom of the frame, using the baffle to close the through trough, and combining the limiting mechanism, the material is collected and safely unloaded, preventing the material from rolling out.
This reduces the difficulty of cleaning up accumulated material at the lowest end of the conveyor, ensures the safety of workers, and avoids safety accidents caused by forgetting to pull out the baffle.

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to fully understand the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.
[0020] Please refer to Figs. 1 to 3This application provides a device for preventing material spillage from a belt conveyor, including a frame 1 and a mobile carriage 2. A belt conveyor 3 is installed inside the frame 1, and a through groove is provided on the frame 1, located below the lowest end of the belt conveyor 3. A T-block 4 is fixedly installed on the mobile carriage 2. A baffle 5 is slidably engaged on the frame 1, and a T-groove 6 is provided on the baffle 5. The T-block 4 is slidably engaged in the T-groove 6. An observation plate 7 is hinged to the frame 1. When the mobile carriage 2 is located at the through groove, the mobile carriage 2 is flush with the frame 1 and the two abut against each other. When the mobile carriage 2 slides out of the through groove, the baffle 5 slides out together to close the through groove. A limiting mechanism is provided on the frame 1 for limiting the movement of the mobile carriage 2 and supporting the baffle 5. A pusher block 12 is installed inside the frame 1.
[0021] In this embodiment, the frame 1 serves as a protective cover for the belt conveyor 3. The portion of the frame 1 below the drive shaft of the belt conveyor 3 can be used to construct the mobile cart 2, making the surface of the mobile cart 2 integrated with the frame 1, thus serving as part of the protective cover. During normal production, the mobile cart 2 is pushed into the through slot at the bottom of the frame 1 to receive material. When the operator observes from the observation plate 7 that the mobile cart 2 is full of accumulated material, the mobile cart 2 can be pulled out to clean the accumulated material inside. During the pulling out, the mobile cart 2 slides out along with the baffle 5 via the T-block 4. After the baffle 5 completely closes the through slot, the mobile cart 2 is pulled to the other side, allowing the T-block 4 to slide along the T-block 4. The extension direction of the groove 6 slides out, thereby separating the moving cart 2 from the baffle 5. When the cart is carrying materials, the limiting mechanism can limit it to prevent the moving cart 2 from moving due to the impact of the materials. When the moving cart 2 moves, the limiting mechanism is removed. After the baffle 5 closes the through groove, the limiting mechanism supports the baffle 5 to prevent it from breaking. After the moving cart 2 unloads materials or a new moving cart 2 is replaced, the T-block 4 can slide back into the T-groove 6. When the moving cart 2 is pushed into the frame 1, the baffle 5 can be pushed back together. When the baffle 5 is pushed back, the materials accumulated on it can be pushed down by the push block 12, so that the materials fall back into the moving cart 2.
[0022] In some embodiments, to facilitate the limiting of the mobile vehicle 2 and the protection of the baffle 5, a limiting mechanism is provided, including a fixed groove 8, a limiting groove 9 and a U-shaped frame 10. The fixed groove 8 is provided on the frame 1 and the limiting groove 9 is provided on the mobile vehicle 2. When the mobile vehicle 2 is located at the through groove, both ends of the U-shaped frame 10 are slidably engaged in the fixed groove 8 and the limiting groove 9, respectively. When the baffle 5 closes the through groove, one end of the U-shaped frame 10 is still slidably engaged in the fixed groove 8, and the other end of the U-shaped frame 10 abuts against the bottom of the baffle 5. Therefore, when the mobile cart 2 receives materials, both ends of the U-shaped frame 10 can be respectively locked in the fixed groove 8 on the frame 1 and the limiting groove 9 on the mobile cart 2. Thus, the limiting of the U-shaped frame 10 makes the mobile cart 2 less likely to move due to the impact of materials. When the mobile cart 2 receives materials, the T-shaped block 4 is blocked by the frame 1, so the mobile cart 2 will not move laterally. When the mobile cart 2 needs to be moved, the U-shaped frame 10 can be removed. When the baffle 5 closes the through groove, the U-shaped frame 10 can be reinserted into the fixed groove 8. At this time, the bottom end of the U-shaped frame 10 will abut against the bottom of the baffle 5 and support it, making it less likely to break.
[0023] In some embodiments, to further improve the support effect of the U-shaped frame 10 on the baffle 5, the bottom of the baffle 5 is provided with a slot 11 adapted to the U-shaped frame 10. This increases the support contact area between the U-shaped frame 10 and the baffle 5, thereby increasing the support effect.
[0024] In some embodiments, to facilitate pushing down the material piled up on the baffle 5, the pusher block 12 is set with its top end closer to the bottom of the belt conveyor 3 and its bottom end further away from the belt conveyor 3 at an angle. This prevents the material piled up on the baffle 5 from becoming too high under the pusher block 12; if it does become too high, it can be pushed down first by the protruding part at the top of the pusher block 12.
[0025] In some embodiments, to facilitate the movement of the mobile vehicle 2, a handle 13 is provided on the mobile vehicle 2.
[0026] In some embodiments, a handle 14 is provided on the observation plate 7 to facilitate rotation.
[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
