Description

Technical Field

[0001] This utility model relates to the technical field of ore conveying devices, specifically an ore conveying device with a protective structure. Background Technology

[0002] Ore conveyor belts are widely used conveying equipment in the mining industry, primarily for transporting ore from the mining site to processing or storage areas. This equipment typically consists of a conveyor belt, drive unit, rollers, tensioning device, and support frame. An existing mining ore conveyor device with a protective structure (Publication No.: CN222409919U) has the following disadvantages in use:

[0003] During operation, guide cylinders are installed on two baffles for easy connection to external feeding devices. Both sides of the guide cylinders are equipped with buffer mechanisms, which consist of an upper clamping plate, a lower clamping plate, a motor mounting base, a second motor, a lead screw, a buffer plate, and lining blocks. These mechanisms buffer the ore falling onto the conveyor belt, preventing significant impact from ore falling from a height. However, when the ore is large, larger stones falling onto the conveyor belt during transport can cause strong impact and friction. This impact can accelerate conveyor belt wear and even lead to belt breakage, reducing the equipment's lifespan. Therefore, this patent proposes an ore conveying device with a protective structure to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an ore conveying device with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ore conveying device with a protective structure, including a mounting frame, a conveyor frame installed at the bottom of the mounting frame, a conveyor belt installed inside the conveyor frame, a first rotating rod and a second rotating rod rotatably connected between the inner walls of the two sides of the mounting frame, multiple breaker hammers fixed on the outer walls of the first rotating rod and the second rotating rod, a driving gear and a driven gear rotatably connected to one side of the mounting frame, the driving gear and the driven gear meshing with each other, and one end of the first rotating rod and the second rotating rod passing through the mounting frame and being fixed to the driving gear and the driven gear respectively.

[0006] Preferably, a first buffer plate and a second buffer plate are rotatably connected between the inner walls of the two sides of the mounting bracket, with the first buffer plate located above the second buffer plate.

[0007] Preferably, a first rotating shaft and a second rotating shaft are rotatably connected between the inner walls of the two sides of the mounting frame. The first rotating shaft is located below the first buffer plate, and the second rotating shaft is located below the second buffer plate. Multiple eccentric blocks are fixed to the outer walls of both the first and second rotating shafts. A motor is fixed to the other side of the mounting frame. The output end of the motor passes through the mounting frame and is fixed to the first rotating shaft. A first synchronous pulley and a second synchronous pulley are rotatably connected to one side of the mounting frame. A first synchronous belt is provided between the first and second synchronous pulleys. One end of the first rotating shaft and the second rotating shaft passes through the mounting frame and is fixed to the first and second synchronous pulleys respectively.

[0008] Preferably, a third synchronous pulley and a fourth synchronous pulley are rotatably connected to the other side of the mounting frame, a second synchronous belt is provided between the third synchronous pulley and the fourth synchronous pulley, and a second rotating shaft and a first rotating rod are fixed to the third synchronous pulley and the fourth synchronous pulley respectively after passing through the mounting frame.

[0009] Preferably, a first mounting rod and a second mounting rod are rotatably connected between the inner walls of the two sides of the mounting frame, a first buffer plate is fixed to the outer wall of the first mounting rod, and a second buffer plate is fixed to the outer wall of the second mounting rod.

[0010] Preferably, a controller is mounted on one end of the mounting bracket, and the controller is electrically connected to the motor.

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

[0012] The drive gear rotates the driven gear, which in turn drives the first and second rotating rods to rotate the breaker hammer to crush the ore. The crushed ore falls onto the conveyor belt for transport, preventing larger pieces from causing strong impact and friction, which would accelerate conveyor belt wear or even damage the belt and reduce the equipment's lifespan.

[0013] In addition, by starting the motor, the motor drives the first rotating shaft to rotate, the first rotating shaft drives the first synchronous pulley to rotate, the first synchronous pulley drives the first synchronous belt to move, the first synchronous belt drives the second synchronous pulley to rotate, causing the second rotating shaft to rotate, the first rotating shaft and the second rotating shaft to rotate, the eccentric block to rotate, the eccentric block to rotate, and the first buffer plate and the second buffer plate to move, thereby causing the stones on the first buffer plate and the second buffer plate to fall off and avoid blockage.

[0020] 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.

[0021] Ore conveyor belts are widely used conveying equipment in the mining industry, mainly used to transport ore from the mining site to the processing or storage area. This equipment typically consists of a conveyor belt, drive unit, rollers, tensioning device, and support frame. The ore conveying device with a protective structure provided by this invention allows ore to fall from the mounting frame 1 onto the first buffer plate 3, then onto the second buffer plate 4 for cushioning, before being crushed by the breaker hammer 7. The crushed ore then falls onto the conveyor belt within the conveyor frame 2 for transport.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: an ore conveying device with a protective structure, including a mounting frame 1, a conveying frame 2 installed at the bottom of the mounting frame 1, a conveyor belt installed inside the conveying frame 2, a first rotating rod 5 and a second rotating rod 6 rotatably connected between the inner walls of the two sides of the mounting frame 1, a plurality of breaker hammers 7 fixed on the outer walls of the first rotating rod 5 and the second rotating rod 6, a driving gear 20 and a driven gear 21 rotatably connected to one side of the mounting frame 1, the driving gear 20 and the driven gear 21 meshing with each other, and one end of the first rotating rod 5 and the second rotating rod 6 passing through the mounting frame 1 and being fixed to the driving gear 20 and the driven gear 21 respectively.

[0023] It should be noted that the conveyor belt is existing technology and will not be elaborated on here. The drive gear 20 drives the driven gear 21 to rotate, which in turn drives the first rotating rod 5 and the second rotating rod 6 to rotate the breaker hammer 7 to crush the ore. The crushed ore falls onto the conveyor belt for transport, preventing larger pieces from causing strong impact and friction, which would accelerate conveyor belt wear or even damage, thus reducing the equipment's lifespan.

[0024] like Figure 2 , Figure 4 and Figure 5 As shown, a first buffer plate 3 and a second buffer plate 4 are rotatably connected between the inner walls of the two sides of the mounting frame 1, with the first buffer plate 3 located above the second buffer plate 4. A first rotating shaft 8 and a second rotating shaft 9 are rotatably connected between the inner walls of the two sides of the mounting frame 1, with the first rotating shaft 8 located below the first buffer plate 3 and the second rotating shaft 9 located below the second buffer plate 4. Multiple eccentric blocks 10 are fixed to the outer walls of both the first rotating shaft 8 and the second rotating shaft 9. A motor 12 is fixed to the other side of the mounting frame 1, with the output end of the motor 12 passing through the mounting frame 1 and fixed to the first rotating shaft 8. A first synchronous pulley 13 and a second synchronous pulley 14 are rotatably connected to one side of the mounting frame 1, with a first synchronous belt 15 provided between the first synchronous pulley 13 and the second synchronous pulley 14. One end of the first rotating shaft 8 and the second rotating shaft 9 passes through the mounting frame 1 and is fixed to the first synchronous pulley 13 and the second synchronous pulley 14, respectively. On the other side of the mounting frame 1, a third synchronous pulley 17 and a fourth synchronous pulley 18 are rotatably connected. A second synchronous belt 19 is provided between the third synchronous pulley 17 and the fourth synchronous pulley 18. The second rotating shaft 9 and the first rotating rod 5 pass through the mounting frame 1 and are fixed to the third synchronous pulley 17 and the fourth synchronous pulley 18 respectively.

[0025] It should be noted that by starting the motor 12, the motor 12 drives the first rotating shaft 8 to rotate, the first rotating shaft 8 drives the first synchronous pulley 13 to rotate, the first synchronous pulley 13 drives the first synchronous belt 15 to move, the first synchronous belt 15 drives the second synchronous pulley 14 to rotate, causing the second rotating shaft 9 to rotate. The rotation of the first rotating shaft 8 and the second rotating shaft 9 drives the eccentric block 10 to rotate, the eccentric block 10 drives the first buffer plate 3 and the second buffer plate 4 to move, thereby causing the stones on the first buffer plate 3 and the second buffer plate 4 to fall and avoid blockage. In addition, the rotation of the second rotating shaft 9 drives the third synchronous pulley 17 to rotate, the third synchronous pulley 17 drives the second synchronous belt 19 to move, thereby causing the fourth synchronous pulley 18 to rotate, the fourth synchronous pulley 18 drives the first rotating rod 5 to rotate, the first rotating rod 5 drives the drive gear 20 to rotate, the drive gear 20 drives the driven gear 21 to rotate, thereby causing the second rotating rod 6 to rotate. In this way, the breaker hammer 7 rotates to crush the ore.

[0026] like Figure 3As shown, a first mounting rod and a second mounting rod 11 are rotatably connected between the inner walls of the two sides of the mounting frame 1. A first buffer plate 3 is fixed to the outer wall of the first mounting rod, and a second buffer plate 4 is fixed to the outer wall of the second mounting rod 11. A controller 16 is installed at one end of the mounting frame 1, and the controller 16 is electrically connected to the motor 12.

[0027] It should be noted that the electrical components in this solution are controlled by the controller 16 that is matched with them, and the control circuit can be implemented by those skilled in the art through simple programming. It is common knowledge in the field and is only used without modification. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0028] 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 embodiments and their equivalents.
