Description

Technical Field

[0001] This invention relates to the field of crusher technology, specifically to an automatic balancing device for the discharge receiving plate of a parallel mining crusher. Background Technology

[0002] There are many types of crushers, which are widely used in many sectors such as mining, metallurgy, building materials, highways, railways, water conservancy and chemical industries. In mining, two crushers are usually used in parallel. When two crushers are crushing ore in parallel, the straight line where the discharge ports of the two crushers are located is perpendicular to the direction of movement of the conveyor belt. Because the material falling from the discharge ports of the two crushers is at different speeds, the material falling on the conveyor belt is uneven, and the force on both sides of the conveyor belt is unbalanced, which accelerates the damage of the conveyor belt. Therefore, an automatic balancing device is needed to control the material falling from the discharge ports.

[0003] Existing automatic balancing devices have complex structures, requiring the use of multiple sensors and controllers, making them inconvenient to use and increasing the operating costs of the crusher. Furthermore, the excessive number of internal electronic devices makes subsequent maintenance and repair difficult, affecting the production efficiency of the entire mining production line. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic balancing device for the discharge receiving tray of a parallel mining crusher, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic balancing device for the discharge receiving tray of a parallel mining crusher includes a support frame and further includes: The receiving tray has a fixed plate and a movable plate inside the support frame. A discharge cylinder is fixedly installed on the movable plate. The bottom of the discharge cylinder is provided with a receiving tray connected to the discharge port of the crusher. A baffle is provided on one side of the fixed plate. A transmission block is provided outside the baffle. A movable frame is provided on the side wall of the discharge cylinder. A roller that contacts the transmission block is provided at the bottom of the movable frame. A material discharge box, wherein the support frame is disposed inside the material discharge box, the material discharge box is located above the conveyor belt, and a material discharge plate is slidably disposed inside the material discharge box; The drive mechanism, installed outside the support frame, can drive the blanking plate to slide left and right; A lifting mechanism, connected to the movable plate, is used to adjust the working height of the movable plate and the receiving tray.

[0006] Based on the above technical solutions, the present invention also provides the following optional technical solutions: In one alternative embodiment: the driving mechanism includes a turntable, a transmission rod, a connecting rod, and a transmission plate. The transmission rod is fixedly mounted on the outside of the turntable, and the transmission plate is mounted on the outside of the support frame. One end of the transmission rod passes through the transmission plate and slides with it. A connecting rod is mounted on the side wall of the transmission plate, and one end of the connecting rod passes into the support frame and connects with the material drop plate.

[0007] In one alternative: the lifting mechanism includes a cylinder and a guide rod. The guide rod and the cylinder are provided on one side of the fixed plate. The telescopic end of the cylinder is connected to the movable plate. One end of the guide rod passes through the movable plate and is provided with a limit block. A connecting spring is sleeved on the outside of the guide rod.

[0008] In one alternative, the drive mechanism further includes a limiting component for restricting the direction of movement of the transmission plate.

[0009] In one alternative: the limiting assembly includes a limiting rod and a buffer spring, the limiting rod is fixedly provided on the side wall of the support frame, the transmission plate is slidably disposed between the two limiting rods, and the buffer spring is sleeved on the outside of the limiting rod.

[0010] In one alternative: the side wall of the support frame is provided with a mounting plate, the mounting plate is provided with a motor, and the rotating end of the motor is connected to the turntable.

[0011] In one alternative: a support plate is provided on one side of the fixed plate, the baffle is slidably disposed inside the support plate, and a return spring is provided inside the support plate, one end of the return spring being connected to the baffle.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The automatic balancing device of the discharge receiving pan of the parallel mining crusher has a simple structure, eliminating the need for multiple sensors and control systems. It is installed between the crusher and the conveyor belt. The crushed material falls into the receiving pan. Due to its increased weight, the receiving pan is pressed downwards by the discharge cylinder and the movable frame, causing the two transmission blocks to move away from each other. The baffle slides to both ends, and the material falls into the discharge box. The discharge plate slides back and forth, ensuring that the material falls evenly onto the conveyor belt. The receiving pan controls the opening range of the baffle by the distance it descends, thus achieving automatic balance between the crusher's discharge speed and the baffle's opening and closing.

A movable frame 19 is provided on the side wall of the discharge cylinder 21. A roller 20 that contacts the transmission block 18 is provided at the bottom of the movable frame 19. The material discharge box 5 is located inside the support frame 1. Inclined plates 501 are provided on both sides of the material discharge box 5, and a material discharge chute 502 is provided at the bottom of the material discharge box 5. The material discharge box 5 is located above the conveyor belt 4. A material discharge plate 7 is slidably disposed inside the material discharge box 5, and a through groove 701 is provided on the material discharge plate 7. Broken material falls into the receiving tray 22. The material accumulates along the material discharge cylinder 21 on the baffle 16. Due to the increased weight, the receiving tray 22 is pressed downwards by the material discharge cylinder 21 and the movable frame 19, causing the two transmission blocks 18 to move away from each other. 16 slides to both ends, the mounting groove 201 is opened, and the material falls into the discharge box 5. The discharge plate 7 slides back and forth. When the discharge chute 502 coincides with the through groove 701, the material falls onto the conveyor belt 4, ensuring that the material can fall evenly onto the conveyor belt 4. The receiving plate 22, the discharge cylinder 21 and the baffle 16 can adjust the speed at which the material falls into the discharge box 5, preventing the material from accumulating in the receiving plate 22.
