Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ore crushing, specifically a feeding device for an ore crusher. Background Technology
[0002] Ore crushing is the process of breaking large pieces of ore into smaller pieces by overcoming the cohesive forces between ore molecules through external force. The particle size of the ore has a significant impact on subsequent processing. There are various ore crushing methods, including compression crushing, splitting crushing, fracturing crushing, grinding crushing, and impact crushing. Among these, compression crushing typically uses a rotary crusher. Rotary crushers have advantages such as high production capacity, high working efficiency, small foundation weight, easy start-up, and less flaky product. In the ore crushing process, ore is usually poured directly from the hopper of a transport vehicle into the rotary crusher. However, because the hopper contains a large amount of ore powder, this direct dumping method affects the working efficiency of the rotary crusher. Therefore, we provide a feeding device for an ore crusher to solve the above problems. Utility Model Content
[0003] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a feeding device for an ore crusher, including a base, a screen plate on the top of the base, a plurality of springs between the screen plate and the base, a vibrating motor on the screen plate, and a first conveying line and a second conveying line on the top of the base, the first conveying line being located below the screen plate and the second conveying line being located below the discharge end of the screen plate.
[0004] Preferably, the spring is connected to the base by a pad, and the inner cavity of the spring is provided with a damper, the two ends of which are connected to the sieve plate and the pad, respectively.
[0005] Preferably, the sieve plate consists of a H-shaped frame and a sieve mesh, and the vibration motor is installed at the bottom center of the H-shaped frame.
[0006] Preferably, a hopper is provided on one side of the feed end of the screen plate, and the hopper is connected to the base by a column.
[0007] Preferably, a receiving shell is provided at the discharge port of the hopper, the discharge port of the receiving shell is correspondingly provided with the screen plate, and the receiving shell and the hopper are connected by bolts.
[0008] Preferably, the outer wall of the hopper is provided with a cylinder, and the movable end of the cylinder is provided with a sliding plate, which moves through the side wall of the hopper.
[0009] Preferably, the included angle between the second conveyor line and the base is between 20° and 30°, and the conveyor belt of the second conveyor line is provided with a number of equally spaced baffles.
[0010] The beneficial technical effects of this utility model are as follows: the feeding device can screen larger volumes of ore and ore powder through the screen plate. The ore powder can be transported and collected through the first conveyor line, while the larger volumes of ore can slide to the input end of the second conveyor line and be transported to the feed port of the rotary crusher. This feeding method avoids ore powder occupying the crushing space of the rotary crusher and further improves the crushing efficiency of the rotary crusher.
[0011] The feeding device has a hopper at the input end of the screen plate. With the cooperation of the cylinder and the slide plate, it controls the amount of ore and ore powder conveyed from the hopper to the screen plate, ensuring that the screen plate can uniformly screen the ore and ore powder, making the screening more thorough.
[0012] The feeding device, through the overall coordination of the hopper, screen plate and the second conveyor line, enables the ore to enter the crushing chamber of the rotary crusher at a uniform speed, avoiding the situation where the ore supports each other and cannot enter the crushing chamber.

[0017] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0018] This utility model proposes a feeding device for an ore crusher, including a base 1. A screen plate 2 is mounted on the top of the base 1. The screen plate 2 consists of a U-shaped frame and a screen mesh. Baffle plates are integrally formed on both sides of the U-shaped frame to prevent ore and ore powder from sliding out from the sides of the screen plate 2. Mounting grooves are provided at the four corners of the bottom of the U-shaped frame, and springs 3 are fixed in the mounting grooves. Springs 3 are connected to the base 1 via pads 12, which are fixedly mounted on the top of the base 1. Pads 12 can raise the height of the screen plate 2, providing space for the ore powder to fall, and can also control the tilt angle of the screen plate 2. The bottom end of the spring 3 is fixed in the mounting cavity of the pad 12, and a damper 13 is provided inside the spring 3. The two ends of the damper 13 are connected to the screen plate 2 and the pad 12, respectively. The design of the damper 13 can effectively reduce vibration and noise, ensuring the screening of ore and ore powder by the screen plate 2, and improving the stability of the equipment. For extended service life, a vibrating motor 4 is installed on the screen plate 2. The vibrating motor 4 is installed at the bottom center of the H-shaped frame. The vibrating motor 4 serves as a power source to provide power for the vibration of the screen plate 2, and the installation position can ensure the uniformity of the vibration of the screen plate 2. The top of the base 1 is provided with a first conveyor line 5 and a second conveyor line 6. The first conveyor line 5 is located below the screen plate 2, and the second conveyor line 6 is located below the discharge end of the screen plate 2. Both the first conveyor line 5 and the second conveyor line 6 are composed of a mounting frame, a drive roller, a conveyor belt, and a motor, and are used for conveying materials. This is existing technology and will not be described in detail here. Since rotary crushers are generally set at a certain height, the included angle between the second conveyor line 6 and the base 1 is set between 20° and 30° so that the output end of the second conveyor line 6 corresponds to the feed port of the rotary crusher. Several equally spaced baffles are provided on the conveyor belt of the second conveyor line 6 to prevent the ore from sliding down the conveyor belt of the second conveyor line 6.
[0019] A hopper 7 is provided on one side of the feed end of the screen plate 2. The hopper 7 is connected to the base 1 by a column 11. The design of the hopper 7 allows the ore and ore powder in the transfer vehicle to be poured into it at once, and the ore and ore powder fall to the top of the screen plate 2 through the hopper 7. Cylinders 9 are provided on both sides of the outer wall of the hopper 7. A sliding plate 10 is provided at the movable end of the cylinder 9. The sliding plate 10 moves through the side wall of the hopper 7. The two cylinders 9 are synchronously driven to ensure the stable movement of the sliding plate 10. A receiving shell 8 is provided at the discharge port of the hopper 7. The discharge port of the receiving shell 8 is correspondingly set to the screen plate 2. The receiving shell 8 is bolted to the hopper 7. The design of the receiving shell 8 avoids the ore and ore powder from directly hitting the screen plate 2, achieving a buffering effect. When the receiving shell 8 is deformed or damaged after long-term use, it can be disassembled and replaced.
[0020] For those skilled in the art, all electrical components and parts in this case are general standard parts or parts known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods. All models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires. According to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the working principle below, and the electrical connection is completed by the sequential operation of each electrical component. The detailed connection method is a well-known technology in the art, and the electrical control will not be described further.
[0021] Working principle: When crushing ore, the ore and ore powder in the transfer vehicle can be poured into the hopper 7. Driven by the cylinder 9, the slide plate 10 can extend and retract within the hopper 7, thereby controlling the amount of material discharged from the hopper 7. When the ore volume is large, the slide plate 10 can be adjusted to make it fall. The ore and powder can fall to the receiving shell 8 for buffering. Then, the ore and powder can slide to the top of the inclined screen plate 2. Under the operation of the vibrating motor 4, the ore and powder can be screened. The ore powder can fall directly to the first conveyor line 5 for transfer and collection, while the larger ore volume can slide to the input side of the second conveyor line 6. Under the transportation of the second conveyor line 6, the ore can be discharged into the rotary crusher for crushing. This feeding method avoids the ore powder occupying the crushing space of the rotary crusher, further improving the crushing efficiency of the rotary crusher.
