Description

Technical Field

[0001] This utility model relates to the field of material conveyor technology, and in particular to a material conveyor that prevents material leakage. Background Technology

[0002] Material conveyors are mechanized devices used for the continuous and efficient transport of various bulk materials or packaged goods along a fixed path. They are widely used in factories, mines, ports, warehouses, construction sites, and many other fields, using belts or chains to move materials horizontally, inclined, or vertically. Material conveyors not only significantly improve material handling efficiency and reduce manual labor intensity and costs, but also enable automated integration of production processes. They are an indispensable infrastructure in modern industrial logistics and production lines, and come in various types, which can be selected and designed according to material characteristics and process requirements.

[0003] When using a conveyor belt to transport materials, in order to prevent material leakage from both sides of the conveyor belt during transport, the existing technology sets two baffles on both sides of the conveyor belt. The bottom of the baffles abuts against the conveyor belt. The material falls onto the conveyor belt for transport, and the two baffles limit the movement of the conveyor belt on both sides, thereby preventing material leakage during transport.

[0004] However, in actual use, since the conveyor belt is always in a state of transmission during material transportation, and in order to reduce material leakage, the bottom of the baffle needs to be in contact with the conveyor belt. With long-term use, the baffle will wear out, resulting in gaps between it and the conveyor belt. Material can easily leak through the gaps, reducing the efficiency of the conveyor. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that the baffle will wear down after long-term use, and the powder will easily leak from the worn part of the baffle when conveying materials, so as to propose a material conveyor that prevents material leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a material conveyor to prevent material leakage, including a conveyor frame, two transmission rollers symmetrically rotatably connected inside the conveyor frame, a transmission belt driving between the two transmission rollers, and a material leakage prevention component, the material leakage prevention component including two blocking frames, the blocking frames symmetrically arranged on both sides of the conveyor frame, the blocking frames being fixedly connected to the conveyor frame, a rotating shaft rotatably connected inside the blocking frame, a blocking box fixedly connected to the circumferential side of the rotating shaft, a sliding groove opened inside the blocking frame, a sliding plate slidably connected in the sliding groove, and an extrusion plate fixedly connected between the two sliding plates, the extrusion plate abutting against the blocking box.

[0008] Preferably, a U-shaped plate is fixedly connected between the two blocking frames, a threaded rod is threadedly connected to the U-shaped plate, a connecting sleeve is fixedly connected to the surface of the extrusion plate, and the connecting sleeve is rotatably connected to the threaded rod.

[0009] Preferably, a rotating block is fixedly connected to the end of the threaded rod.

[0010] Preferably, a blocking strip is inserted into the blocking box, and a number of limiting blocks are movably connected to the surface of the blocking strip. A number of limiting holes are opened on the surface of the blocking box, and the limiting blocks and limiting holes are inserted into each other.

[0011] Preferably, the blocking strip is made of rubber.

[0012] Preferably, the two blocking boxes are at the same angle to the conveyor belt.

[0013] Preferably, the length of the blocking box is greater than the length of the conveyor frame.

[0014] Preferably, the skateboard is L-shaped.

[0015] The material conveyor proposed in this utility model has the following advantages: by rotating the threaded rod, the threaded rod moves downward and pushes the pressing plate downward, thereby increasing the pressing force of the pressing plate on the blocking box. This makes the blocking strip and the conveyor belt more tightly connected when conveying some fine powder, thus improving the leakage prevention capability of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-4 This utility model is a material conveyor for preventing material leakage, including a conveyor frame 1, two transmission rollers 2 symmetrically rotatably connected inside the conveyor frame 1, a transmission belt 3 driving between the two transmission rollers 2, a motor 4 fixedly connected to the side of the conveyor frame 1, the output end of the motor 4 fixedly connected to one of the transmission rollers 2, and a material leakage prevention component, including two blocking frames 5, the blocking frames 5 symmetrically arranged on both sides of the conveyor frame 1, the blocking frames 5 fixedly connected to the conveyor frame 1, a rotating shaft 6 rotatably connected inside the blocking frame 5, a blocking box 7 fixedly connected to the side of the rotating shaft 6, a sliding groove 8 opened inside the blocking frame 5, a sliding plate 9 slidably connected inside the sliding groove 8, and an extrusion plate 10 fixedly connected between the two sliding plates 9, the extrusion plate 10 abutting against the blocking box 7.

[0025] The operation process of this embodiment is as follows: The material to be transported is placed on the surface of the conveyor belt. The motor 4 drives the conveyor roller 2 to rotate. Due to the transmission cooperation between the conveyor roller 2 and the conveyor belt 3, the conveyor belt 3 moves between the two conveyor rollers 2 to transport the material on its surface. In the initial state, the two blocking boxes 7 will fall along the rotating shaft 6 under the influence of gravity, and the bottom will abut against the conveyor belt 3. As the conveyor belt 3 is transported, the blocking boxes 7 can block the material on the conveyor belt 3, preventing the material from falling from both sides of the conveyor belt 3 during the transport process. Compared with the existing technology of fixing two baffles on both sides of the conveyor frame and abutting against the conveyor belt 3, the blocking boxes 7 in this device can rotate along the rotating shaft 6 and abut against the conveyor belt 3 under the influence of gravity. Even if the blocking boxes 7 in this device wear out after long-term use, they can still abut against the bottom conveyor belt 3, thereby avoiding the wear of the baffles after long-term use and reducing the material leakage prevention capability.

[0026] When transferring finer materials, the baffle box 7 is prone to warping. To address this, a sliding groove 8 is provided within the two baffle frames 5. The sliding groove 8 slidably connects the slide plate 9 and the extrusion plate 10. The extrusion plate 10 is positioned as follows: Figure 1 As shown, the extrusion plate 10 can apply a downward force to the two bottom blocking boxes 7, thereby preventing the blocking boxes 7 from warping during transmission and further improving the ability to prevent material leakage.

[0027] Example 2

[0028] Under certain conditions, the pressure exerted on the blocking box 7 by the weight of the pressing plate alone is insufficient, and material may still leak from the gap between the conveyor belt 3 and the blocking box 7. Therefore, please refer to [the relevant documentation / reference needed]. Figure 2-3 Based on the first specific embodiment, a rotating block 14 is fixedly connected to the end of the threaded rod 12, a blocking strip 15 is inserted into the blocking box 7, a number of limiting blocks 16 are movably connected to the surface of the blocking strip 15, a number of limiting holes 17 are opened on the surface of the blocking box 7, and the limiting blocks 16 and the limiting holes 17 are inserted into each other. The blocking strip 15 is made of rubber. The angle between the two blocking boxes 7 and the conveyor belt 3 is the same. The length of the blocking box 7 is greater than the length of the conveyor frame 1. The slide plate 9 is L-shaped.

[0029] The operation process of this embodiment is as follows: The rotatable rotating block 14 rotates and drives the threaded rod 12 to rotate. Since the threaded rod 12 and the U-shaped plate 11 are threadedly engaged, and the connecting sleeve 13 on the surface of the pressing plate is rotatedly engaged with the threaded rod 12, rotating the rotating block 14 can adjust the position of the slider in the slide groove 8, thereby adjusting the pressure applied by the pressing plate to the blocking box 7. When conveying some fine powder, the pressure applied to the blocking box 7 can be increased, so that the blocking box 7 and the conveyor belt 3 fit more tightly, and the powder is prevented from leaking out from the gap between the blocking box 7 and the conveyor belt 3.

[0030] As the device continues to be used, the blocking box 7 will experience some wear and tear, making replacement inconvenient. To address this, a blocking strip 15 is inserted into the blocking box 7, with a movable limiting block 16 on the blocking strip 15. After pressing the limiting block 16 into the blocking strip 15, the blocking strip 15 is then inserted into the blocking box 7. A spring is installed between the limiting block 16 and the blocking strip 15, pushing the limiting block 16 into the limiting hole 17 to limit the blocking strip 15. Thus, when the blocking strip 15 wears out and needs to be replaced, similarly, pressing the limiting block 16 removes the blocking strip 15 from the blocking box 7 for replacement, further improving the device's practicality.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
