Description

Technical Field

[0001] This utility model relates to the field of industrial unloading technology, specifically to a buffer and anti-pressure device for ore discharge ports. Background Technology

[0002] In the process of ore smelting and processing, the ore lifted by the main elevator is unloaded into the silo through the bottom discharge skip. The ore particles are further discharged from the discharge port at the bottom of the silo. In the existing technology, the silo is fed into the conveyor belt by a vibrating feeder, and the belt is transported to the intermediate crusher for further crushing.

[0003] During use, the following problems exist: Due to the high moisture content of the ore, reaching up to 8%, and the large amount of powder, severe mudification occurs, leading to serious blockage of the feed inlet. To reduce the blockage, a vibrating feeder was installed at the bottom of the silo in the direction of the belt conveyor. The blockage situation has been somewhat improved, but because the feed inlet at the bottom of the silo is close to the belt conveyor, the ore impacts the belt severely. If the belt is not started in time, it is easy to press on the belt, and if the belt cannot be started, the drive roller will slip and damage the belt. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a buffer and anti-pressure device for ore discharge ports, which solves the problem of heavy pressure on the material conveyor belt after material is discharged from the discharge port during the ore unloading process.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a buffer and anti-pressure device for ore discharge port, including a discharge hopper, with a material conveyor belt installed at the bottom of the discharge hopper; A buffer device is provided between the material conveyor belt and the hopper. The buffer device includes a horizontally arranged bidirectional belt conveyor located directly below the discharge port of the hopper. The length of the bidirectional belt conveyor is less than the length of the material conveyor belt, and both ends of the bidirectional belt conveyor are located above the material conveyor belt.

[0006] Optionally, the material conveyor belt includes a support frame and a drive motor. The drive motor is fixed to the side of the support frame, and a buffer frame is fixed above the support frame. The bidirectional belt conveyor is fixed on the buffer frame.

[0007] Optionally, the bidirectional belt conveyor includes a first conveyor belt and a second conveyor belt that are close together at the front and rear. The first conveyor belt and the second conveyor belt are jointly mounted on a buffer frame, and the pivot positions of the first conveyor belt and the second conveyor belt correspond to each other.

[0008] Optionally, the first conveyor belt's shaft is connected to a first servo motor, and the second conveyor belt's shaft is connected to a second servo motor. The first servo motor and the second servo motor are respectively fixed on the front and rear sides of the buffer frame, and the first servo motor and the second servo motor rotate in opposite directions.

[0009] Optionally, a first guide groove and a second guide groove are respectively provided at the ends of the rotating shafts of the first and second conveyor belts that are close to each other. Guide rods of appropriate length are installed in the first guide groove and the second guide groove. A first bearing is rotatably arranged between the inner wall of the first guide groove and the guide rod, and a second bearing is rotatably arranged between the inner wall of the second guide groove and the guide rod.

[0010] Optionally, a material distribution plate is provided on the hopper. The material distribution plate is arranged horizontally and can divide the discharge port of the hopper into two sets of discharge ports, the front and rear discharge ports corresponding to the belts of the bidirectional belt conveyor.

[0011] Optionally, a movable rod is rotatably inserted through the top of the material distribution plate, and the movable rod is horizontally fixed on the inner walls of the left and right sides of the hopper.

[0012] This utility model provides a buffer and anti-pressure device for an ore feed port, which has the following beneficial effects: This utility model provides a buffer and anti-pressure device for ore discharge ports. By setting up a bidirectional belt conveyor between the discharge port and the material conveyor belt, the bidirectional belt conveyor includes two sets of belts rotating in opposite directions. This allows the material falling from the hopper to be diverted left and right on the bidirectional belt conveyor, and then fall onto the material conveyor belt below from both ends of the bidirectional belt conveyor. This avoids the material from the hopper falling directly onto the material conveyor belt and accumulating, which would cause the motor to overload when the material conveyor belt starts. Furthermore, a material distribution plate is set in the discharge port of the hopper, corresponding to the two sets of belts of the bidirectional belt conveyor, making it easier for the bidirectional belt conveyor to divert the material from the discharge port. This solves the technical problem of heavy pressure on the material conveyor belt after the material is discharged from the discharge port during the ore unloading process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a buffer and anti-pressure device for an ore discharge port, including a discharge hopper 1, a material conveyor belt 2 at the bottom of the discharge hopper 1, and a buffer device between the material conveyor belt 2 and the discharge hopper 1. The buffer device includes a horizontally arranged bidirectional belt conveyor 3. The material in the hopper is diverted by the bidirectional belt conveyor 3 to prevent it from accumulating on the material conveyor belt 2 below, thereby preventing the material conveyor belt 2 from starting under overload. The bidirectional belt conveyor 3 is located directly below the discharge port of the discharge hopper 1. The material conveyor belt 2 includes a support frame 4 and a drive motor 5. The drive motor 5 is fixed to the side of the support frame 4, and a buffer frame 6 is fixed above the support frame 4. The bidirectional belt conveyor 3 is fixed on the buffer frame 6 to provide a way for the bidirectional belt conveyor 3 to be fixed on the material conveyor belt 2. The length of the bidirectional belt conveyor 3 is less than the length of the material conveyor belt 2, and both ends of the bidirectional belt conveyor 3 are located above the belt of the material conveyor belt 2, ensuring that the material can fall onto the material conveyor belt 2 below from both ends of the bidirectional belt conveyor 3.

[0017] In this embodiment, as a preferred solution, the bidirectional belt conveyor 3 includes a first conveyor belt 11 and a second conveyor belt 21 that are close together at the front and rear. The first conveyor belt 11 and the second conveyor belt 21 are jointly mounted on a buffer frame 6, and the pivot positions of the first conveyor belt 11 and the second conveyor belt 21 are corresponding, so that the first conveyor belt 11 and the second conveyor belt 21 can be rotatably mounted on the same set of buffer frames 6, reducing the space occupied by the bidirectional belt conveyor 3 above the material conveyor belt 2. The pivot of the first conveyor belt 11 is driven to a first servo motor 12, and the pivot of the second conveyor belt 21 is driven to a second servo motor 22. The first servo motor 12 and the second servo motor 22 are respectively fixed on the front and rear sides of the buffer frame 6, and the rotation directions of the first servo motor 12 and the second servo motor 22 are opposite, ensuring that the conveying directions of the first conveyor belt 11 and the second conveyor belt 21 are opposite, so that the material falling on the bidirectional belt conveyor 3 can be diverted front and rear and fall from the left and right ends of the bidirectional belt conveyor 3 respectively.

[0018] Specifically, the first conveyor belt 11 and the second conveyor belt 21 have concave first guide grooves 101 and 201 respectively at their close-to-each shaft ends. Guide rods 7 of suitable length are installed in the first guide grooves 101 and 201. A first bearing 13 is rotatably arranged between the inner wall of the first guide groove 101 and the guide rod 7, and a second bearing 23 is rotatably arranged between the inner wall of the second guide groove 201 and the guide rod 7. The guide rods 7 of suitable length are used to provide support connection between the two sets of transmission belts at the center of the buffer frame 6. The first bearing 13 rotatably arranged on the guide rod 7 can rotate synchronously with the shaft of the first conveyor belt 11, and the second bearing 23 rotatably arranged on the guide rod 7 can rotate the belt synchronously with the shaft of the second conveyor belt 21, so that the two sets of conveyor belts can achieve synchronous rotation in opposite directions.

[0019] In this embodiment, as a preferred solution, a material distribution plate 8 is provided on the hopper 1. The material distribution plate 8 is arranged horizontally and can divide the discharge port of the hopper 1 into two sets of discharge ports, front and rear. The front and rear discharge ports correspond to the belts of the bidirectional belt conveyor 3, which makes it easier for the material falling from the discharge port to fall accurately on the front and rear sets of belts of the bidirectional belt conveyor 3, making the material distribution more accurate and convenient. A movable rod 9 is rotatably inserted through the top of the material distribution plate 8. The movable rod 9 is horizontally fixed on the inner wall of the left and right sides of the hopper 1. The material distribution plate 8 is a movable plate that can swing back and forth. For the discharge of irregular ore blocks, the material distribution plate 8 can swing appropriately to make room for the material to fall, making the discharge port more convenient.
