[0002] With the development of society and technology, equipment in various fields has been greatly improved. Ball mill is the key equipment for crushing materials after they are broken. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers and other production industries. In order to facilitate the staff to feed materials into the ball mill, the feeding device can be used to automatically feed materials into the ball mill, which greatly improves the feeding efficiency and reduces the workload of the staff.

[0003] After searching, the publication number CN220195042U, the application date 2023.04.18 discloses a ball mill feeding device for copper concentrate beneficiation, which belongs to the technical field of copper concentrate beneficiation.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0032] See also Figures 1 to 4 The utility model is a feeding device for a ball mill, comprising a ball mill body 1 and a feeding pipe 101 arranged at the center of an outer wall on one side thereof, a conveying cylinder 102 is slidably connected inside the feeding pipe 101, a hydraulic cylinder 104 is installed below an outer wall on one side of the ball mill body 1, a buffer assembly 2 is arranged at the inner end of the conveying cylinder 102; the buffer assembly 2 comprises an adjusting plate 201 and movable grooves 2011 arranged at the front and rear ends of the outer wall thereof, and the inner wall of the adjusting plate 201 is movably connected to the inner end of the conveying cylinder 102 through a hinge.

[0033] Specifically, a conveying mechanism 1021 is provided inside the conveying cylinder 102, a support plate 1022 is fixedly connected to one side of the bottom of the conveying cylinder 102, the inner wall of the support plate 1022 is connected to the telescopic end of the hydraulic cylinder 104, a crushing box 103 is installed on one side of the top of the conveying cylinder 102, a crushing mechanism 1031 is provided inside the crushing box 103, a feed pipe 1032 is provided at the bottom center of the crushing box 103, the bottom end of the feed pipe 1032 is provided on one side of the top of the conveying cylinder 102, the front and rear ends of the top side of the adjusting plate 201 are connected to the electric push rod 202 by hinges, and the other end of the electric push rod 202 is connected to the conveying cylinder 102 by a hinge. The outer wall of the feeding tube 102 is movably connected, and a supporting plate 203 is provided at the outer end of the adjusting plate 201. Connecting plates 2031 are fixedly connected at the front and rear edges of the inner wall of the supporting plate 203. A conical slide plate 204 is provided at the center position of the inner wall of the supporting plate 203. A connecting rod 205 is fixedly connected at the center position of the other end of the connecting plate 2031. The other end of the connecting rod 205 passes through the through hole inside the fixing ring 206 and is connected with the limiting plate 207. A spring 208 is sleeved on the outer side of the outer wall of the connecting rod 205. The spring 208 is located between the fixing ring 206 and the limiting plate 207. The outer wall of the fixing ring 206 is fixed on the inner wall of the movable groove 2011.

[0034] Furthermore, the conveying cylinder 102 can be sealed and slid inside the feed pipe 101, and the inclination angle of the adjustment plate 201 can be adjusted by a hinge. The conveying mechanism 1021 and the crushing mechanism 1031 are both existing technologies, so they will not be described in detail here. The position of the conveying cylinder 102 can be adjusted by the hydraulic cylinder 104, and the angle of the adjustment plate 201 can be adjusted under the action of the electric push rod 202. The conical slide plate 204 can cause the material on its surface to slide down. Under the action of the connecting plate 2031 and the connecting rod 205, the support plate 203 and the limit plate 207 can be connected to play a role of connecting transmission. Under the action of the elastic performance of the spring 208, the force on the support plate 203 can be reduced to play a buffering role.

[0035] The operation process of this embodiment is as follows: first, the material to be ground is put into the crushing box 103, and then the crushing mechanism 1031 inside the crushing box 103 is used to crush the material. The crushed material falls into the conveying cylinder 102 through the discharge pipe 1032, and the material inside the conveying cylinder 102 is conveyed to the inside of the ball mill body 1 through the conveying mechanism 1021. Then, the hydraulic cylinder 104 is started, and the operation of the hydraulic cylinder 104 drives the support plate 1022 at the bottom of the conveying cylinder 102 to move, thereby driving the conveying cylinder 102 to move inside the feed pipe 101 and adjust the depth of its discharge port inside the ball mill body 1. At the same time, the electric push rod 202 is started, and the telescopic end of the electric push rod 202 extends to push the adjustment plate 201 to move, wherein the inner end of the adjustment plate 201 is movably connected to the discharge port of the conveying cylinder 102 through a hinge, so that By adjusting the inclination angle of the adjustment plate 201, the height of the material falling can be reduced. At the same time, when the material falls, it will first fall on the surface of the conical slide plate 204 on the inner wall of the outer support plate 203. At this time, the conical slide plate 204 is forced to drive the support plate 203 to move outward, wherein the inner wall of the support plate 203 is connected to the limit plate 207 through the connecting plate 2031 and the connecting rod 205. Therefore, when the support plate 203 moves, it will drive the limit plate 207 to move under the action of the connecting plate 2031 and the connecting rod 205, and squeeze the spring 208. Under the action of the elastic performance of the spring 208, it can play a buffering role, which plays a buffering role for the falling material. Therefore, after the material has been reduced in height and the buffering effect, the impact force of falling into the inner wall of the ball mill body 1 can be reduced, thereby reducing the loss to the ball mill body 1 and increasing the service life. Specific embodiment 2

[0037] See also Figure 1 , 5 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a dust suction component 3 is provided, the dust suction component 3 includes a dust collecting box 301 and a dust inlet pipe 3011 arranged at the bottom of its front end surface, and the other end of the dust inlet pipe 3011 is connected to the fan 302 through a pipe joint, which solves the problem that the fine dust generated by the existing crushing mechanism during the material crushing process will be scattered in the working environment, posing a safety hazard to the health of the workers.

[0038] Specifically, the air inlet end of the fan 302 is connected to the connecting pipe 3021 through a pipe joint, the other end of the connecting pipe 3021 is connected to two groups of delivery pipes 3022 through a three-part joint, and the other end of the delivery pipe 3022 is connected to the dust suction pipe 303 through a pipe joint.

[0039] Furthermore, the pipe joint plays the role of connecting the pipelines. The operation of the fan 302 can suck the dust through the two sets of dust suction pipes 303, and then enter the dust collecting box 301 through the two sets of conveying pipes 3022 and the dust inlet pipe 3011 for centralized collection and treatment, thereby preventing the dust from overflowing.

[0040] The operation process of this embodiment is as follows: a large amount of dust will be generated when the material is put into the crushing box 103 and falls into the conveying cylinder 102 through the discharge pipe 1032. At this time, the fan 302 is started, and the fan 302 operates to suck the dust generated in the discharge process through the two sets of dust suction pipes 303, and then transports it through the two sets of conveying pipes 3022 and the connecting pipe 3021, and finally sucks the dust into the dust collecting box 301 through the dust inlet pipe 3011. The dust can be sucked in and collected for centralized treatment, thereby preventing the dust generated in the crushing and discharge process from being scattered in the environment and inhaled by the staff, posing a safety hazard.
