Description

Technical Field

[0001] This utility model relates to the technical field of scraper conveyors for coal mines, specifically a scraper conveyor for coal mines with a protective mechanism. Background Technology

[0002] A scraper conveyor is a conveyor that uses a scraper chain to transport bulk materials in a trough. A scraper conveyor whose adjacent middle troughs can bend to a limited extent in the horizontal and vertical planes is called a flexible scraper conveyor. Among them, a working face conveyor with its body bent at 90 degrees at the intersection of the working face and the transport roadway is called a "corner scraper conveyor". In the current coal mining face, the scraper conveyor not only transports coal and materials, but also serves as the running track for the coal mining machine. Therefore, it has become an indispensable main piece of equipment in modern coal mining technology. As long as the scraper conveyor can keep running continuously, production can proceed normally. Otherwise, the entire coal mining face will be in a state of shutdown, causing the entire production to be interrupted.

[0003] In existing technology, a protective plate is installed on top of the scraper conveyor to prevent coal chunks from falling off, thus ensuring greater safety for workers.

[0004] However, in actual use, since the protective plate is fixed to the conveying device after installation, when too many coal blocks are conveyed, the coal blocks will get stuck between the protective plate, which will reduce the conveying efficiency of the coal blocks. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a scraper conveyor for coal mines with a protective mechanism. This solves the problem that, in actual use, when too much coal is being conveyed, the protective plate, which is fixed to the conveying device after installation, can cause obstruction between the coal and the protective plate, thus reducing the conveying efficiency of the coal.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a scraper conveyor for coal mines with a protective mechanism, comprising a conveying pipe, a conveyor belt installed inside the conveying pipe, a mounting frame rotatably connected to the bottom of the conveying pipe via a pin, a protective shell pressed against the top of the conveyor belt, a bracket fixedly connected to the top of the protective shell, a protective cloth fixedly connected to the upper part of the inner wall of the protective shell, a locking block fixedly connected to the lower part of the outer wall of the protective shell, a fixing block sleeved on the outer wall of the locking block, the outer wall of the fixing block fixedly connected to the outer wall of the conveying pipe, and a sealing device installed between the conveying pipe and the protective shell.

[0007] Preferably, the sealing device includes a sealing plate, the outer wall of which abuts against the inner wall of the protective shell and the conveying pipe, and a limiting block is fixedly connected to the outer wall of the sealing plate, the outer wall of which is inserted between the protective shell and the conveying pipe.

[0008] Preferably, the inner wall of the fixing block is threaded with a bolt, which extends to one side of the fixing block and is inserted into the inner wall of the locking block.

[0009] Preferably, a top plate is provided below the mounting bracket, and a threaded rod is rotatably connected to the top of the top plate via a sealed bearing. The outer wall of the threaded rod is threaded to the inner wall of the mounting bracket, and a handle is fixedly connected to the top of the threaded rod.

[0010] Preferably, a hydraulic rod is rotatably connected to the top side of the mounting bracket, and the top of the hydraulic rod is rotatably connected to the bottom of the delivery pipe via a pin.

[0011] Preferably, a support rod is fixedly connected to the outer wall of the conveying pipe, and the outer wall of the support rod is fixedly connected to the protective net. Beneficial effects

[0012] This utility model provides a scraper conveyor for coal mines with a protective mechanism. It offers the following advantages: This scraper conveyor with a protective mechanism, through the cooperation of a protective shell, a support frame, and a protective cloth, uses locking blocks and fixing blocks to install the protective shell on top of the conveyor pipe. Furthermore, the protective cloth on top of the protective shell has good extensibility, ensuring that coal blocks above the conveyor belt will not affect the protective shell during transport. This solves the problem that when the protective plate is fixed to the conveying device after installation, jamming between the coal blocks and the protective plate occurs when too many coal blocks are transported, leading to a reduction in coal transport efficiency.

[0013] By using the mounting frame, top plate, and threaded rod together, when the scraper conveyor is in use, turning the threaded rod with the handle causes the top plate to move up and down through the threaded connection between the threaded rod and the mounting frame, thus pressing the top plate firmly against the ground. This fixes the conveying device in place and solves the problem of the conveying device shaking during operation. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] In actual use, since the protective plate is fixed to the conveying device after installation, when too many coal blocks are conveyed, the coal blocks will get stuck between the protective plate, which will reduce the conveying efficiency of the coal blocks.

[0018] In view of this, the present invention provides a scraper conveyor for coal mines with a protective mechanism, which solves the problem that in actual use, when too much coal is conveyed, the protective plate is fixed on the conveying device after installation, which will cause the coal to get stuck between the coal and the protective plate, thus reducing the conveying efficiency of the coal.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Example 1: By Figure 1-4 It is known that the scraper conveyor for coal mines with a protective mechanism includes a conveying pipe 1, a conveyor belt 11 installed inside the conveying pipe 1, a mounting frame 2 rotatably connected to the bottom of the conveying pipe 1 via a pin, a protective shell 3 pressed against the top of the conveyor belt 11, a bracket 5 fixedly connected to the top of the protective shell 3, a protective cloth 4 fixedly connected to the upper part of the inner wall of the protective shell 3, a locking block 10 fixedly connected to the lower part of the outer wall of the protective shell 3, a fixing block 15 sleeved on the outer wall of the locking block 10, the outer wall of the fixing block 15 fixedly connected to the outer wall of the conveying pipe 1, and a sealing device installed between the conveying pipe 1 and the protective shell 3. In the specific implementation process, it is worth noting that the conveyor belt 11 is composed of a conveyor chain and a scraper. The scraper is installed on the top of the conveyor chain to stabilize the coal blocks during conveying. A drive device is installed on the outer wall of the conveying pipe 1 to drive the conveyor belt 11 to rotate, so that the coal blocks are stable during conveying. The protective shell 3 is a long C-shaped plate, and a protective cloth 4 is fixedly connected to its top to prevent the coal blocks from affecting the protective shell 3 during conveying. The protective cloth 4 is made of nylon, which has good wear resistance. At the same time, the support 5 supports the protective shell 3 to avoid excessive pressure on the protective shell 3, which could cause damage. When installing the protective shell 3, the locking block 10 is inserted into the fixing block 15 on the outer wall of the conveying pipe 1 to align the protective shell 3 with the conveying pipe 1. Furthermore, the sealing device includes a sealing plate 12, the outer wall of which abuts against the inner wall of the protective shell 3 and the conveying pipe 1, and a limiting block 16 is fixedly connected to the outer wall of the sealing plate 12, with the outer wall of the limiting block 16 inserted between the protective shell 3 and the conveying pipe 1. In the specific implementation process, it is worth noting that when installing the protective shell 3, the sealing plate 12 is placed outside the gap between the protective shell 3 and the conveying pipe 1, and a slot corresponding to the limiting block 16 is opened at the position where the protective shell 3 and the conveying pipe 1 fit together. When installing the protective shell 3, the limiting block 16 is stuck between the protective shell 3 and the conveying pipe 1. This can ensure that the sealing plate 12 is pressed tightly against the gap between the protective shell 3 and the conveying pipe 1, so as to avoid affecting the protective shell 3 and the conveying pipe 1 when conveying coal blocks. Furthermore, the inner wall of the fixing block 15 is threaded with a bolt 17, which extends to one side of the inside of the fixing block 15 and is inserted into the inner wall of the locking block 10. In the specific implementation process, it is worth noting that after the protective shell 3 is installed, the bolt 17 is inserted into the inside of the fixing block 15 and passes through the fixing block 15. One end of the bolt is inserted into the inside of the clamping block 10. This way, the clamping block 10 and the fixing block 15 can be together, and the protective shell 3 can be fixed to the top of the conveying pipe 1.

[0021] Example 2: From Figure 1-4 It can be seen that a top plate 9 is provided below the mounting frame 2, and a threaded rod 13 is rotatably connected to the top of the top plate 9 through a sealed bearing. The outer wall of the threaded rod 13 is threaded to the inner wall of the mounting frame 2, and a handle 14 is fixedly connected to the top of the threaded rod 13. In the specific implementation process, it is worth noting that when the scraper conveyor is in use, the handle 14 drives the threaded rod 13 to rotate. Since the inner wall of the mounting frame 2 is provided with the same internal thread as the outer wall of the threaded rod 13, when the handle 14 drives the threaded rod 13 to rotate, the threaded rod 13 will move inside the mounting frame 2, so that the top plate 9 is pressed against the ground. This will support the entire device and ensure the stability of the entire device during operation. At the same time, the traveling wheels at the bottom of the mounting frame 2 will not separate from the ground. This reduces the stress on the traveling wheels at the bottom of the mounting frame 2 and prevents the mounting frame 2 from moving accidentally during operation, ensuring the overall stability of the device. The specific dimensions of the mounting frame 2 and the number of top plates 9 can be set according to actual needs. It is necessary to ensure the overall stability of the scraper conveyor with protective mechanism in the coal mine, and not to cause instability of the center of gravity due to the pressure of coal blocks or external forces, so as to avoid tipping over. Of course, when necessary, steel pipes or other effective support structures can be used to support the scraper conveyor with protective mechanism in the coal mine to improve stability. For example, support rod structures can be welded to the bottom of the conveying pipe 1. Furthermore, a hydraulic rod 8 is rotatably connected to the top side of the mounting bracket 2, and the top of the hydraulic rod 8 is rotatably connected to the bottom of the delivery pipe 1 via a pin. In the specific implementation process, it is worth noting that when conveying the scraper conveyor, the hydraulic rod 8 is used to support the conveying pipe 1, and when adjusting the angle of the conveying pipe 1, the hydraulic rod 8 is used to push the conveying pipe 1 to change the overall angle of the conveying pipe 1. Furthermore, a support rod 6 is fixedly connected to the outer wall of the conveying pipe 1, and the outer wall of the support rod 6 is fixedly connected to the protective net 7; In the specific implementation process, it is worth noting that the support rods 6 are set on both sides of the outer wall of the conveying pipe 1, and the protective net 7 fixed to the outer wall of the support rods 6 will block the coal blocks falling into the conveying pipe 1 to avoid injury to the workers. The protective net 7 can be made of rope, which has a good buffering effect.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
