Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a grinding medium sub-packaging device for a grinding mill. Background Art

[0002] Mineral resource mining is not only an important foundation for industrial development, but also one of the key driving forces for economic growth and social development. Most of the mined ores need to go through a series of processes such as crushing and grinding before they can be further used. Ball mills can be used to grind ores. Their working principle is mainly based on physical processes such as collision, friction and grinding to grind ores with high quality and high efficiency. After a certain period of use, the grinding steel balls loaded inside the ball mill will also become smaller, resulting in a decrease in grinding efficiency. Therefore, it is necessary to regularly screen and pack the grinding steel balls, and then continue to put them into use according to specifications.

[0003] Since the grinding steel balls are heavy, when existing equipment screens them and then contains them, the steel balls leave the screening mechanism very quickly, causing the rapidly ejected steel balls to easily injure people. Also, when the steel balls are contained, the impact force caused by their inertia causes the container to easily deform and be damaged, making it difficult to contain. Therefore, the screened grinding steel balls need to be slowed down before being collected. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] Embodiment 1:

[0026] This embodiment provides a grinding medium packing device for a grinding mill, specifically, Figure 1-Figure 7 As shown, it includes a bracket 1 and a separation component 2 installed on the bracket 1, the separation component 2 includes a separation box, and a plurality of discharge ports are arranged on the separation box, and an interception component 3 for decelerating the grinding balls is installed at each of the discharge ports.

[0027] The interception assembly 3 includes a discharge barrel 301 connected to the discharge port, the discharge barrel 301 is rotatably connected to the buffer disk 302, the buffer disk 302 is fixedly mounted with a rotating sleeve 303, the rotating sleeve 303 is fixedly connected with N interception rods 304 for intercepting grinding balls, and the buffer disk 302 is provided with N slots, N is a positive integer and greater than 2; the discharge barrel 301 is fixedly mounted with a support rod 306, the support rod 306 is rotatably connected with a limiting claw 305, the limiting claw 305 and the support rod 306 are connected by a torsion spring 309, and the limiting claw 305 hooks the slot on the buffer disk 302 to limit the buffer disk 302. The length of the interception rod 304 at different discharge ports is determined according to the size of the discharged grinding balls.

[0028] When the grinding balls are screened in the separation box, they begin to be discharged into the interception assembly 3 through the discharge port. After the faster grinding balls enter the interception assembly 3, they are blocked by the interception rod 304 and stop. When the personnel overcome the elastic force of the torsion spring 309 and move the limit claw 305 so that it no longer hooks the slot on the buffer plate 302, the buffer plate 302 and the rotating sleeve 303 lose their limit, and the grinding balls begin to continue rolling and slowly slide out of the discharge barrel 301 under the action of gravity. In this process, the grinding balls will also push the interception rod 304 that intercepts them, causing the rotating sleeve 303 to rotate. The rotation of the rotating sleeve 303 will also drive the buffer plate 302 to rotate synchronously. When the buffer plate 302 rotates, the limit claw 305 is pressed on the surface of the buffer plate 302 due to the elastic force of the torsion spring 309. At the same time, when the rotating sleeve 303 rotates, the other interception rod 304 will rotate to the position of blocking the next grinding ball. At this time, the limit claw 305 hooks another slot, realizing the interception of the next grinding ball by the interception rod 304.

[0029] Through the above arrangement, the grinding balls that fall quickly from the separation box are successfully intercepted and then slowly slide out of the discharge barrel 301, which effectively reduces the discharge speed of the grinding balls, is conducive to the staff to pack the grinding balls with containers, and prevents the grinding balls from being ejected at high speed and hitting people; at the same time, the impact force of the grinding balls on the containers is reduced, thereby protecting the containers.

[0030] Embodiment 2:

[0031] This embodiment is further expanded on the basis of Embodiment 1. Figure 7 As shown, the buffer plate 302 is slidably connected to the buffer sheet 311 at the slot position, and a buffer spring 312 is provided between the buffer sheet 311 and the buffer plate 302 .

[0032] During the rotation of the buffer disk 302, after the grinding ball contacts the intercepting rod 304, the limiting claw 305 hooks the buffer plate 311. At this time, the buffer spring 312 is compressed by the impact of the grinding ball; when the grinding ball rolls out of the discharge barrel 301, the buffer plate 311 is reset under the action of the buffer spring 312.

[0033] Through the above arrangement, the impact force of the grinding ball on the interception rod 304 can be reduced, preventing the interception rod 304 from bending and deforming after being impacted for a long time.

[0034] like Figure 5 As shown, an intercepting motor 308 is installed on the discharge cylinder 301 , and a cam 307 is fixedly connected to the intercepting motor 308 , and the cam 307 is used for intermittently pushing the limiting claw 305 .

[0035] By starting the intercepting motor 308, the cam 307 intermittently pushes the limit claw 305, so that the grinding balls are automatically discharged regularly; by changing the rotation speed of the intercepting motor 308, the grinding ball discharge speed can be adjusted, and the control is convenient and fast.

[0036] like Figure 5 As shown, the limit claw 305 is provided with a protrusion 310, and the cam 307 cooperates with the protrusion 310. By using the cam 307 to push the protrusion 310, the volume of the cam 307 can be reduced while maintaining the range of the limit claw 305, thereby reducing the space occupied.

[0037] Embodiment 3:

[0038] This embodiment is further expanded on the basis of Embodiment 1 or Embodiment 2. Figure 1-Figure 2 As shown, the bracket 1 includes a fixed frame 101, a group of first springs 102 and a group of second springs 103 are installed on the fixed frame 101, the separation box is installed on the fixed frame 101 through the first spring 102 and the second spring 103, a vibration motor 105 is installed on the separation box, the separation box includes a separation box shell 201 and a separation box cover 203 installed on the separation box shell 201, a feed hopper 202 is installed on the separation box cover 203, and a plurality of separation filter plates 204 are arranged in the separation box, and filter holes are opened on the separation filter plates 204. The design of the filter hole diameters on different separation filter plates 204 should follow the rule of decreasing from top to bottom. The vibration motor 105 is a commercially available product, and the specific model is the adaptability selection of those skilled in the art, which will not be repeated here.

[0039] The grinding balls are poured into the feed hopper 202 and then fall onto the top separation filter plate 204. With the vibration generated by the vibration motor 105, the grinding ball assemblies of different sizes begin to separate, and then the grinding balls of the same specifications are discharged from the same discharge port into the interception assembly 3.

[0040] like Figure 8 As shown, the fixing frame 101 is threadedly connected with an adjusting bolt 104, and the adjusting bolt 104 is rotatably connected with an adjusting piece 106, and the adjusting piece 106 is connected to the second spring 103. According to the actual specific operation conditions, the adjusting bolt 104 can be rotated to make the adjusting piece 106 rise and fall to adjust the inclination angle of the separation box, thereby adjusting the separation and discharge speed of the grinding balls.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
