Description

Technical Field

[0001] The utility model relates to the field of ball mills, and particularly to a feeding buffer mechanism for a ball mill. Background Art

[0002] A ball mill is a commonly used ore grinding device for grinding raw materials into fine powders or mixed materials. In the operation of a ball mill, feeding is a very important link, which affects the grinding efficiency and quality. Generally, there are various feeding methods for ball mills, including direct feeding and indirect feeding. Direct feeding means directly putting the raw materials into the grinding chamber of the mill for grinding, while indirect feeding is to send the raw materials into the mill through equipment such as conveyor belts and bucket elevators, which can not only control the feeding speed and quantity but also reduce the dust flying.

[0003] For example, a feeding port buffer mechanism for a ball mill proposed in the publication number CN220531857U. By setting a buffer assembly, during feeding, as the material flow continuously enters, the first buffer unit and the second buffer unit constantly intersect with each other. It can not only buffer the material flow, slow down the material flow rate, and avoid the material flow falling at high speed from directly impacting the feeding port of the ball mill, resulting in damage to the feeding port of the ball mill, but also clean the materials stuck in the buffer grille by means of the impact of the material flow, avoid the situation of material jamming and blockage, ensure the feeding effect, and thus ensure the working efficiency of the ball mill.

[0004] When the above device is in use, it utilizes the continuous intersection of the first buffer unit and the second buffer unit to buffer the materials, avoiding the situation that the material flow falling at high speed directly impacts the feeding port of the ball mill, resulting in damage to the feeding port of the ball mill. However, after being impacted by the materials, the first buffer unit and the second buffer unit are not stable during the alternating process, and at the same time, the overall buffer effect is not good.

[0005] At the same time, in the existing ball mills during use, due to rapid feeding and discharging, the continuous falling of materials will cause intermittent impact of the materials on the inner wall of the feeding device. The long-term continuous and intermittent impact will cause serious wear on the inner wall of the feeding device, and further greatly reduce the overall service life.

[0006] Based on the above description, it is necessary to improve it. Therefore, a feeding buffer mechanism for a ball mill is proposed. Content of the Utility Model

[0007] Aiming at the technical problems existing in the prior art, the utility model provides a feeding buffer mechanism for a ball mill. By the mutual cooperation of a lifting component and a buffer component, the moving plate can continuously move up and down while having a good buffer effect, thereby solving the problems of instability and poor buffer effect during the alternating process.

[0008] The technical solution of the present utility model to solve the above technical problems is as follows: A feeding buffer mechanism for a ball mill, including a blanking frame, an elevating assembly is installed inside the blanking frame, and a buffer assembly is installed above the elevating assembly. The elevating assembly includes a cylinder, a fixed block, a moving plate and a connecting block. The bottom of the cylinder is fixedly connected to the center of the top surface of the fixed block, and the top of the cylinder is fixedly connected to the bottom of the moving plate. One end of the moving plate is inclined. The bottoms of the connecting blocks are respectively fixed at the four corners of the top surface of the moving plate, and a limiting post is fixedly installed on the inner wall of the connecting block.

[0009] Preferably, a chute is provided on the inner wall of the blanking frame, and one side of the fixed block is fixedly connected to the inside of the blanking frame. The other end of the moving plate is in contact with the inner wall of the blanking frame.

[0010] Preferably, the buffer assembly includes a buffer plate, a movable column, a first buffer spring, a second buffer spring, a connecting plate, a limiting block and a movable rod. A sliding block is fixedly installed on one side of the buffer plate, and the outer surface of the sliding block is slidably connected to the inside of the chute.

[0011] Preferably, the other end of the buffer plate is inclined and is parallel to one end of the moving plate. The top surface of the movable column is fixedly connected to the bottom surface of the buffer plate, and the bottom of the movable column is fixedly connected to one end of the first buffer spring.

[0012] Preferably, the other end of the first buffer spring is fixedly connected to the top surface of the moving plate. One end of the movable rod is movably connected to the inner wall of the connecting plate, and the top of the connecting plate is fixedly connected to the bottom of the buffer plate.

[0013] Preferably, the other end of the movable rod is movably connected to the inner wall of the limiting block. The outer surface of the limiting post passes through the inside of the limiting block, and the two are slidably connected.

[0014] Preferably, both ends of the second buffer spring are fixedly connected to the inner wall of the limiting block, and the inside of the second buffer spring is in contact with the outer surface of the limiting post. Both the moving plate and the buffer plate are located inside the blanking frame.

[0015] The beneficial effects of the present utility model are as follows: Through the settings of the air cylinder, the moving plate, the buffer plate, and the first buffer spring, the output end of the air cylinder can drive the moving plate and the buffer plate to perform repeated up and down movements. The buffer plate can convert the impact force it receives into a downward pressure and transmit it to the connecting plate and the movable column. The first buffer spring can buffer and dissipate the pressure received by the movable column to a certain extent. When the connecting plate receives the pressure brought by the buffer plate, the movable rod drives the limiting blocks to continuously approach each other, and the second buffer spring is compressed. Through the compression, the pressure brought by the buffer plate can be offset. Thus, through the mutual cooperation of the air cylinder, the first buffer spring, and the second buffer spring, the overall buffer effect of the device is improved, and thus the impact generated during the descent of the material can be effectively prevented from damaging the inside of the blanking frame;

[0016] Through the cooperation of structures such as the buffer assembly provided, the service life of the blanking frame is improved, the overall impact resistance is enhanced, and the continuous rolling impact of the material during the blanking process inside the blanking device is greatly reduced, which causes wear to the blanking device. On this basis, the maintenance intensity is greatly reduced, and potential safety hazards are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0029] Embodiment 1

[0030] Please refer to Figures 1 to 7As shown in the figure, the utility model provides a ball mill feeding buffer mechanism, which includes a feeding frame 1. An elevating assembly 2 is installed inside the feeding frame 1, and a buffer assembly 3 is installed above the elevating assembly 2. The elevating assembly 2 includes a cylinder 21, a fixed block 22, a moving plate 23 and a connecting block 24. The bottom of the cylinder 21 is fixedly connected to the center of the top surface of the fixed block 22, and the top of the cylinder 21 is fixedly connected to the bottom of the moving plate 23. One end of the moving plate 23 is inclined. The bottoms of the connecting blocks 24 are respectively fixed at the four corners of the top surface of the moving plate 23, and a limiting column 241 is fixedly installed on the inner wall of the connecting block 24.

[0031] Through the setting of the cylinder 21, the output end of the cylinder 21 can be used to drive the moving plate 23 to move up and down repeatedly, so that the buffer plate 31 moves synchronously under the influence of the moving plate 23. Through the setting of the limiting column 241, the position of the limiting block 36 can be restricted to a certain extent, so that the limiting block 36 can only move on the outer surface of the limiting column 241. At the same time, it can effectively prevent the bottom of the limiting block 36 from contacting the top of the moving plate 23.

[0032] Embodiment 2

[0033] Please refer to Figures 4 to 5 As shown in the figure, the buffer assembly 3 includes a buffer plate 31, a movable column 32, a first buffer spring 33, a second buffer spring 34, a connecting plate 35, a limiting block 36 and a movable rod 37. A sliding block is fixedly installed on one side of the buffer plate 31, and the outer surface of the sliding block is slidably connected to the inside of the chute. The other end of the buffer plate 31 is inclined and parallel to one end of the moving plate 23. The top surface of the movable column 32 is fixedly connected to the bottom surface of the buffer plate 31, and the bottom of the movable column 32 is fixedly connected to one end of the first buffer spring 33. The other end of the first buffer spring 33 is fixedly connected to the top surface of the moving plate 23. One end of the movable rod 37 is movably connected to the inner wall of the connecting plate 35, and the top of the connecting plate 35 is fixedly connected to the bottom of the buffer plate 31. The other end of the movable rod 37 is movably connected to the inner wall of the limiting block 36. The outer surface of the limiting column 241 passes through the inside of the limiting block 36, and the two are slidably connected.

[0034] Through the setting of the buffer plate 31, the impact force generated during the falling process of the material can be converted into a downward pressure, and the pressure can be smoothly transmitted to the first buffer spring 33 and the movable rod 37 through the movable column 32 and the connecting plate 35. By using the mobility of the movable rod 37, the limiting blocks 36 are continuously close to each other, and the second buffer spring 34 is compressed. Thus, the force generated when the first buffer spring 33 and the second buffer spring 34 are compressed cancels out the pressure brought by the buffer plate 31, thereby achieving a good buffer effect.

[0035] The working principle and usage process of the utility model:

[0036] First, the staff installs the cylinder 21 and the moving plate 23 inside the blanking frame 1, and then starts the cylinder 21. The output end of the cylinder 21 drives the moving plate 23 and the buffer plate 31 to move up and down.

[0037] Then, blanking starts. When the buffer plate 31 contacts the falling material, the impact force generated by the falling of the material is converted into a downward pressure. When the movable column 32 and the connecting plate 35 receive the pressure brought by the buffer plate 31, the movable column 32 will drive the first buffer spring 33 to continuously contract by using the elasticity of the spring. At the same time, under the extrusion of the connecting plate 35, the movable rod 37 will drive the limiting blocks 36 to approach each other. During this process, the second buffer spring 34 continuously contracts due to the extrusion of the limiting blocks 36. The pressure consumed when the first buffer spring 33 and the second buffer spring 34 contract cancels out the pressure brought by the buffer plate 31. When the material leaves the top of the buffer plate 31, the first buffer spring 33 and the second buffer spring 34 will drive the buffer plate 31 to return to its original state under the action of inertia, so that the buffer plate 31 can continuously receive the impact force generated by the falling of the material.

[0038] It should be noted that in the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0039] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
