Description

Technical Field

[0001] The present invention relates to the technical field of ball mills, and particularly to a vibrating planetary ball mill. Background Art

[0002] A planetary ball mill is a high-efficiency and precision grinding equipment, which is widely used in the fields of materials science, chemistry, electronics, medicine, geology, etc., for crushing, mixing, and homogenizing various hard, soft, brittle, and wet materials.

[0003] For example, Chinese Patent CN208260889U discloses a planetary ball mill for lead-zinc ore, which includes a base, a cover body, a rotating disk, and a grinding mechanism. The rotating disk is arranged on the base, and a motor for driving the rotating disk to rotate is arranged in the base. The cover body is arranged on the base. The rotating disk is provided with mounting holes that extend outward from the center of the rotating disk. The grinding mechanism is arranged on the mounting holes through sliders. The grinding mechanism includes a grinding tank and a fixing component for fixing the grinding tank. Steel balls for grinding lead-zinc ore are arranged in the grinding tank. By using the high-speed tumbling of the steel balls and the grinding sample in the grinding tank, strong shearing, impact, and rolling are generated on the grinding sample to achieve crushing, grinding, dispersion, and emulsification of the material.

[0004] In the above solution, the grinding tank rotates to drive the grinding balls in the grinding tank to collide at high speed. The grinding balls in the tank collide with each other during high-speed movement to grind and mix the sample. However, due to reasons such as intermolecular forces, during the working process of the planetary ball mill, the sample is prone to the phenomenon of sticking to the wall, resulting in the inability of the planetary ball mill to efficiently grind the sample to the specified size during operation. At the same time, the material will accumulate at the bottom for a long time, causing uneven distribution. Summary of the Invention

[0005] Based on this, in view of the problem that the material is prone to adhere to the side wall during grinding by the current ball mill, resulting in uneven grinding, it is necessary to provide a vibrating planetary ball mill.

[0006] The above object is achieved by the following technical solutions: A vibrating planetary ball mill, comprising: A base, on which a rotating disk is rotatably arranged. A plurality of support cylinders are circumferentially and evenly rotatably arranged on the rotating disk. A grinding tank is installed inside the support cylinder, and a plurality of steel balls are placed in the grinding tank; A corrugated sleeve, which is coaxially sleeved on the outer periphery of the grinding tank, and the corrugated sleeve has corrugated protrusions along its axial direction; A vibrating sleeve, which is coaxially and axially slidably arranged inside the side wall of the support cylinder. Bullet heads are distributed along the radial direction on the inner side wall of the vibrating sleeve. The bullet heads are in sliding contact with the outer periphery of the corrugated sleeve, and the bullet heads have a tendency to push against the outer periphery of the corrugated sleeve.

[0007] Further, a fixed sleeve is rotatably connected to the bottom of the support cylinder. The fixed sleeve is fixedly arranged on the rotating disk. A first sliding tooth is arranged at the top end of the fixed sleeve, and a second sliding tooth is arranged at the bottom of the support cylinder. The first sliding tooth is in sliding fit with the second sliding tooth. A first elastic member is axially arranged at the bottom of the support cylinder, and the first elastic member can maintain the sliding fit between the first sliding tooth and the second sliding tooth.

[0008] Further, a third sliding tooth is arranged at the bottom end of the vibration sleeve. The third sliding tooth is in sliding fit with the first sliding tooth, and the axial moving directions of the third sliding tooth and the second sliding tooth are opposite.

[0009] Further, a second elastic member is arranged at the top of the vibration sleeve, and the second elastic member can maintain the sliding fit between the third sliding tooth and the first sliding tooth.

[0010] Further, a driving component is arranged on the base. The driving component can drive the rotating disk to rotate around its own axis and drive the support cylinder to rotate around its own axis.

[0011] Further, the driving component includes a driving motor and a driving disk. The driving disk is rotatably arranged on the base. The driving motor is in transmission connection with the driving disk. The driving disk is coaxially and fixedly connected with the rotating disk. A fixed gear disk is coaxially and fixedly arranged on the base. A transmission gear is coaxially and fixedly connected to the bottom of the support cylinder, and the transmission gear is meshed with the fixed gear disk.

[0012] Further, a belt is wound between the rotating shaft of the driving motor and the driving disk.

[0013] Further, a chute extending along the radial direction thereof is formed on the inner wall of the vibration sleeve. A compression spring is arranged in the chute. The bullet head is slidably arranged in the chute. The compression spring can push the bullet head to extend out of the chute. One end of the bullet head in sliding contact with the outer periphery of the corrugated sleeve is a spherical surface.

[0014] Further, a dust-proof cover is detachably arranged on the base.

[0015] Further, the tank body has upper and lower parts.

[0016] The beneficial effects of the present invention are: In the present invention, a corrugated sleeve is provided on the outer periphery of the tank body, a vibration sleeve is provided inside the side wall of the support cylinder, and the projectile on the vibration sleeve is in sliding contact with the outer periphery of the corrugated sleeve. When the vibration sleeve moves axially back and forth, the projectile hammers the corrugated sleeve, causing the corrugated sleeve to vibrate and transmit to the tank body, prompting the material adhered to the side wall of the tank body to fall off, thereby improving the crushing efficiency of the material. Moreover, when the support cylinder rotates relative to the fixed sleeve, through the sliding cooperation of the first sliding tooth and the second sliding tooth, the support cylinder moves axially back and forth, driving the material at the bottom of the tank body to roll up and down. At the same time, the reciprocating movement of the vibration sleeve can further disperse the material at the bottom of the tank body, making the material distribution more uniform and reducing the phenomenon of accumulation at the bottom.

[0017] In the present invention, the third sliding tooth provided at the bottom of the vibration sleeve is in sliding cooperation with the first sliding tooth and has an axial movement direction opposite to that of the second sliding tooth. When the support cylinder moves up and down, the acceleration directions of the two are opposite, which can reduce the dynamic load generated when the support cylinder moves up and down, make the vibration of the vibration sleeve more stable, and then stably strike the corrugated sleeve, reducing the material attached inside the tank body.

[0018] In the present invention, by changing the number of teeth of the first sliding tooth, the second sliding tooth and the third sliding tooth and adjusting them proportionally, the frequency of the reciprocating movement of the support cylinder up and down can be changed, and then the frequency of the projectile hitting the corrugated sleeve can be changed. By installing support cylinders with different frequencies on the rotating disk, grinding and crushing of different grinding intensities or different materials can be carried out simultaneously, improving the versatility and efficiency of the equipment.

[0019] In the present invention, by providing a detachable dust-proof cover on the base, dust can be prevented from entering, avoiding affecting the high-speed revolution and rotation of the tank body. The tank body is designed in two parts up and down, which is convenient for loading materials. Installation holes are provided on the side wall at the upper end of the support cylinder, and the tank body can be conveniently fixed through the fixing plate, the top rod and the lever to prevent it from detaching from the support cylinder.

[0024] In this invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature can be that the first feature is directly above or obliquely above the second feature, or simply means that the first feature has a higher horizontal height than the second feature.

[0025] The following refers to Figures 1 - 13 to describe a vibrating planetary ball mill provided by this invention.

[0026] A vibrating planetary ball mill, suitable for grinding and crushing various particles, includes a base 100. A rotating disk 120 is rotatably arranged on the base 100. The rotating disk 120 can rotate around its own axis. A plurality of support cylinders 200 are circumferentially and evenly rotatably arranged on the rotating disk 120. A grinding tank 400 is installed inside the support cylinder 200. A plurality of steel balls are placed inside the grinding tank 400, and the inside of the grinding tank 400 is used to accommodate the material to be ground and crushed. The rotating disk 120 rotates around its own axis, and the support cylinder 200 can simultaneously rotate around its own axis on the rotating disk 120, so that the grinding tank 400 inside the support cylinder 200 rotates synchronously. When the grinding tank 400 rotates, the steel balls inside collide with the material to grind and crush the material. In the prior art, due to reasons such as intermolecular forces when the grinding tank 400 rotates, the sample in the planetary ball mill is prone to wall sticking during operation. The planetary ball mill cannot efficiently grind the sample to the specified size during operation, and at the same time, the material will accumulate at the bottom for a long time, resulting in uneven distribution.

[0027] Therefore, to overcome the above problems, a corrugated sleeve 410 is coaxially and fixedly arranged on the outer periphery of the tank body 400. The corrugated sleeve 410 has corrugated protrusions in its axial direction. And a vibrating sleeve 250 is axially slidably arranged inside the side wall of the support cylinder 200. The vibrating sleeve 250 can move axially within the support cylinder 200. On the inner side wall of the vibrating sleeve 250, there are bullet heads 300 arranged radially. There are multiple bullet heads 300. The bullet heads 300 can slidably contact the outer periphery of the corrugated sleeve 410, and the bullet heads 300 have a tendency to push against the corrugated sleeve 410. When the vibrating sleeve 250 moves axially within the support cylinder 200, the bullet heads 300 reciprocate on the wavy protrusions on the outer periphery of the corrugated sleeve 410. When the bullet heads 300 move to the depressions between adjacent protrusions, they can hammer the corrugated sleeve 410, causing the corrugated sleeve 410 to vibrate. Since the corrugated sleeve 410 is fixedly arranged on the outer periphery of the tank body 400, the vibration of the corrugated sleeve 410 can be transmitted to the tank body 400, causing the tank body 400 to vibrate synchronously. As a result, the materials adhered to the side wall of the tank body 400 can fall off, thereby improving the crushing efficiency of the materials. And it can also disperse the materials at the bottom of the tank body 400, making the distribution of the materials more uniform.

[0028] Specifically, to achieve the function of the vibrating sleeve 250 moving axially inside the side wall of the support cylinder 200, as Figure 9 and Figure 10 shown, a fixed sleeve 160 is rotatably connected to the bottom of the support cylinder 200. The bottom of the fixed sleeve 160 is fixedly arranged on the rotating disk 120. The support cylinder 200 can rotate relative to the fixed sleeve 160. And a first sliding tooth 170 is arranged at the top of the fixed sleeve 160. A second sliding tooth 210 is arranged at the bottom end of the support cylinder 200. The second sliding tooth 210 is in sliding fit with the first sliding tooth 170. Since the fixed sleeve 160 is fixed on the rotating disk 120, when the support cylinder 200 rotates relative to the fixed sleeve 160, relative sliding occurs between the first sliding tooth 170 and the second sliding tooth 210, so that the second sliding tooth 210 can axially reciprocate relative to the first sliding tooth 170. The second sliding tooth 210 drives the support cylinder 200 to reciprocate axially. Since the vibrating sleeve 250 is inside the side wall of the support cylinder 200, the vibrating sleeve 250 can also move axially inside the side wall of the support cylinder 200.

[0029] It can be understood that when the support cylinder 200 rotates relative to the fixed sleeve 160, through the sliding fit of the first sliding tooth 170 and the second sliding tooth 210, the support cylinder 200 can axially reciprocate, thereby driving the vibrating sleeve 250 to move axially inside the side wall of the support cylinder 200. When the support cylinder 200 axially reciprocates, it can also make the materials at the bottom of the tank body 400 tumble up and down, making the distribution of the materials inside the tank body 400 more uniform. It can also further reduce the materials adhered to the inner wall of the tank body 400 and improve the grinding and crushing effect of the materials inside the tank body 400.

[0030] To prevent the first sliding tooth 170 and the second sliding tooth 210 from disengaging, as Figure 5 and Figure 8 shown, the bottom of the support cylinder 200 in this embodiment has a cavity 220. A first elastic member 230 is axially distributed in the cavity 220. A connecting rod 240 is axially slidably arranged in the cavity 220. The upper end of the connecting rod 240 is fixedly connected to the upper end of the first elastic member 230. The lower end of the first elastic member 230 abuts against the bottom of the cavity 220. The lower end of the connecting rod 240 passes through the cavity 220 and is fixedly connected to the bottom of the fixed sleeve 160. The first elastic member 230 is a compression spring 320. The first elastic member 230 pushes the bottom of the cavity 220 downward to prevent the second sliding tooth 210 and the first sliding tooth 170 on the support cylinder 200 from disengaging.

[0031] In a further embodiment, the vibration sleeve 250 in this embodiment can also reduce the dynamic load generated when the support cylinder 200 moves up and down, as Figure 9 、 Figure 10 、 Figure 11 and Figure 12 shown. A third sliding tooth 260 is further provided at the bottom of the vibration sleeve 250. The third sliding tooth 260 also slidably cooperates with the first sliding tooth 170. However, the axial movement direction of the third sliding tooth 260 is opposite to that of the second sliding tooth 210. For example, when the second sliding tooth 210 moves upward relative to the first sliding tooth 170, the third sliding tooth 260 moves downward relative to the first sliding tooth 170. And when the second sliding tooth 210 moves downward relative to the first sliding tooth 170, the third sliding tooth 260 moves upward relative to the first sliding tooth 170. The advantage of such a setting is that when the second sliding tooth 210 moves upward relative to the first sliding tooth 170, the first sliding tooth 170 gives the second sliding tooth 210 an upward acceleration. At this time, the third sliding tooth 260 moves downward relative to the first sliding tooth 170, and the third sliding tooth 260 has a downward acceleration, thereby reducing the dynamic load generated when the support cylinder 200 moves up and down.

[0032] Specifically, to enable the third sliding tooth 260 to have a downward acceleration when moving downward, as Figure 6 、 Figure 8 and Figure 9As shown in the figure, a second elastic member 270 is provided at the top end of the vibration sleeve 250. The second elastic member 270 is a compression spring 320. The second elastic member 270 pushes the vibration sleeve 250 downward, so that the third sliding tooth 260 at the bottom of the vibration sleeve 250 has a downward acceleration when moving downward relative to the first sliding tooth 170. At this time, the resultant force on the vibration sleeve 250 is zero, so that the vibration of the vibration sleeve 250 is more stable. The vibration of the vibration sleeve 250 can continuously strike the corrugated sleeve 410, so that the tank body 400 vibrates continuously, reducing the materials adhered to the inside of the tank body 400.

[0033] It should be noted that, for the convenience of the second sliding tooth 210 and the third sliding tooth 260 to be slidably engaged with the first sliding tooth 170 respectively, as Figure 9 , Figure 10 and Figure 11 shown, a rectangular groove 350 is formed at the position on the bottom side wall of the support cylinder 200 where the second sliding tooth 210 is located. The rectangular groove 350 enables the teeth of the third sliding tooth 260 to pass through, and the number of the rectangular grooves 350 corresponds to the number of the teeth of the third sliding tooth 260. After the third sliding tooth 260 passes through the rectangular groove 350, it can be slidably engaged with the first sliding tooth 170.

[0034] In a further embodiment, a driving assembly is provided on the base 100 of the present invention. The driving assembly is used to drive the rotating disc 120 to rotate around its own axis and drive the support cylinder 200 to rotate around its own axis. The support cylinder 200 drives the tank body 400 to rotate around its own axis, and the rotating disc 120 drives the tank body 400 to revolve around the axis of the rotating disc 120, so that the steel balls inside the tank body 400 continuously rub the materials to complete the crushing operation.

[0035] It should be noted that, as Figure 13 shown, in this embodiment, the third sliding teeth 260 are circumferentially and uniformly distributed at the bottom of the vibration sleeve 250. The distribution of the third sliding teeth 260 is sparser than that of the first sliding teeth 170, but the moving direction of the third sliding teeth 260 can still be opposite to the moving direction of the second sliding teeth 210, ensuring that the resultant force on the vibration sleeve 250 is zero during the up and down movement.

[0036] It should also be noted that the number of teeth of the first sliding tooth 170, the second sliding tooth 210 and the third sliding tooth 260 in the embodiment of the present invention can be changed, and they are changed proportionally, so as to change the frequency of the up and down reciprocating movement of the support cylinder 200, and further change the frequency of the warhead 300 hitting the corrugated sleeve 410. Different frequency support cylinders 200 can be installed on the rotating disc 120, so as to realize the grinding and crushing of different grinding intensities or different materials at the same time, greatly improving the versatility and efficiency of the vibration planetary ball mill.

[0037] Specifically, asFigure 1 and Figure 2 As shown in Figure 2 , the drive assembly in this embodiment includes a drive motor (not shown in the figure) and a drive disk 130. The drive disk 130 is rotatably arranged on the base 100. The drive disk 130 is coaxial with and fixedly connected to the rotating disk 120. A fixed gear disk 150 is fixedly arranged on the base 100. The fixed disk is coaxial with the drive disk 130 and the rotating disk 120. And the drive disk 130 and the rotating disk 120 are connected by a connecting shaft 140. The connecting shaft 140 passes through the center of the fixed gear disk 150, so that the drive disk 130 and the rotating disk 120 can rotate relative to the fixed gear disk 150. The support cylinder 200 is rotatably connected at the position of the rotating disk 120 and is coaxially and fixedly connected with a transmission gear. The transmission gear meshes with the outer peripheral teeth of the fixed gear disk 150. In this embodiment, the drive motor is fixedly arranged on the base 100. The rotating shaft of the drive motor is in transmission connection with the drive disk 130. When the drive motor is started, the rotating shaft drives the drive disk 130 to rotate around its own axis. The drive disk 130 drives the rotating disk 120 to rotate around its own axis. At this time, the transmission gear on the rotating disk 120 revolves around the fixed gear disk 150. Since the transmission gear meshes with the teeth on the outer periphery of the fixed gear disk 150, the transmission gear rotates around its own axis while revolving around the fixed gear disk 150. The transmission gear drives the support cylinder 200 to rotate around its own axis, so that the tank body 400 inside the support cylinder 200 rotates around its own axis synchronously and revolves around the fixed gear disk 150.

[0038] More specifically, in this embodiment, the rotating shaft of the drive motor and the drive wheel are connected by a belt (not shown in the figure), so that the rotating shaft of the drive motor can drive the drive wheel to rotate.

[0039] It can be understood that the transmission connection between the rotating shaft of the drive motor and the drive disk 130 is not limited to the above belt connection, and can also be a gear transmission connection. The specific transmission connection method is not specifically limited here.

[0040] It should be noted that, in order to achieve the function of enabling the support cylinder 200 to rotate around its own axis and be axially movable, there are two transmission gears in the present invention. For the convenience of description, the two transmission gears are respectively named the first transmission gear 180 and the second transmission gear 190. The first transmission gear 180 is coaxially and fixedly connected to the bottom of the support cylinder 200. Between the first transmission gear 180 and the support cylinder 200, there is a sliding shaft (not shown in the figure). The sliding shaft slidably passes through the rotating disk 120 and can axially move along the rotating disk 120. A fixed frame is provided at the bottom of the rotating disk 120. The second transmission gear 190 is rotatably arranged on the fixed frame and meshes with the first transmission gear 180. The second transmission gear 190 also meshes with the teeth on the outer periphery of the driving disk 130. The first transmission gear 180 does not mesh with the teeth on the outer periphery of the driving disk 130. The first transmission gear 180 drives the second transmission gear 190 to rotate by meshing with the driving disk 130. The second transmission gear 190 then drives the support cylinder 200 to rotate. When the support cylinder 200 axially moves, it will cause the first transmission gear 180 and the second transmission gear 190 to axially slide relative to each other. Moreover, the thicknesses of the first transmission gear 180 and the second transmission gear 190 are greater than the maximum distance of the axial reciprocating movement of the support cylinder 200, so as to prevent the first transmission gear 180 and the second transmission gear 190 from disengaging.

[0041] Specifically, as Figure 7 、 Figure 9 and Figure 13 shown, a plurality of chutes 310 extending radially along the inner wall of the vibration sleeve 250 in the present invention are provided. A compression spring 320 is arranged in the chute 310, and the bullet head 300 is slidably arranged in the chute 310. One end of the compression spring 320 is fixedly connected in the chute 310, and the other end of the compression spring 320 is fixedly connected to the bullet head 300. The compression spring 320 can push the bullet head 300 to extend out of the chute 310 or make the bullet head 300 have a tendency to extend out of the chute 310. When the vibration sleeve 250 axially reciprocates, since the bullet head 300 is in sliding contact with the corrugated sleeve 410, the bullet head 300 continuously retracts and extends out of the chute 310. The compression spring 320 can provide the power for the bullet head 300 to strike the corrugated sleeve 410, thereby causing the tank body 400 inside the support cylinder 200 to vibrate. Moreover, the end of the bullet head 300 in contact with the corrugated sleeve 410 is a spherical surface 330, which is convenient for the bullet head 300 to be in sliding contact with the corrugated sleeve 410, thereby reducing the friction force between the bullet head 300 and the corrugated sleeve 410.

[0042] It should be noted that, for the convenience of the bullet head 300 to pass through the support cylinder 200 and contact the corrugated sleeve 410, as Figure 11As shown, a plurality of vertical through slots 340 are provided on the support tube 200, and the vertical through slots 340 extend along the axial direction of the support tube 200, each vertical through slot 340 corresponds to a bullet 300, and the length of the vertical through slot 340 is related to the maximum amplitude of the up and down vibration of the vibration sleeve 250, and the length of the vertical tube slot is at least greater than the maximum amplitude of the up and down vibration of the vibration sleeve 250, and the plurality of bullets 300 on the vibration sleeve 250 contact with the corrugated sleeve 410 after passing through the vertical through slots 340, and the plurality of bullets 300 can be driven by the vibration sleeve 250 to move up and down so that the bullets 300 can hit the corrugated sleeve 410.

[0043] More specifically, a dust cover 110 is provided on the base 100 in the embodiment of the present invention. The dust cover 110 is detachably provided on the outer periphery of the rotating disk 120. The dust cover 110 covers the rotating disk 120 and multiple support tubes 200 inside, thereby preventing dust from entering and avoiding affecting the high-speed revolution and rotation of the multiple tank bodies 400.

[0044] Specifically, in order to facilitate the fixed installation of the tank body 400, the present invention symmetrically opens mounting holes 280 on the side walls of the upper end of the support tube 200, and the mounting holes 280 are used to install the fixing plates 420. During installation, the fixing plates 420 are first taken out of the mounting holes 280, and then the tank body 400 and the corrugated sleeve 410 are installed in the support tube 200. Subsequently, the fixing plate 420 is passed through the two mounting holes 280, and a push rod 430 is threadedly connected at the middle position of the fixing plate 420, and the lower end of the push rod 430 abuts against the upper end surface of the tank body 400, and a lever 440 is fixedly connected to the upper end of the push rod 430. The operator drives the lever 440 to rotate the push rod 430 so that the push rod 430 tightly abuts the tank body 400 against the inside of the support tube 200 to prevent the tank body 400 from detaching from the support tube 200.

[0045] It should be noted that the tank body 400 of the present invention is composed of two parts, the upper and lower parts. When materials need to be filled, the upper and lower parts of the tank body 400 can be separated, and after filling, the upper and lower parts of the tank body 400 can be combined.

[0046] The specific working process of a vibrating planetary ball mill provided by the present invention is described in combination with the above embodiments: Filling material: Separate the upper and lower parts of the tank body 400, load the steel balls and materials into the tank body 400, and then put the upper and lower parts of the tank body 400 together. Subsequently, sleeve the outer periphery of the tank body 400 with a corrugated sleeve 410, and install the tank body 400 inside the support tube 200. After the fixing plate 420 passes through the mounting hole 280 of the upper end side wall of the support tube 200, the push rod 430 is threadedly connected to the fixing plate 420. The operator pushes the lever 440 on the push rod 430 so that the push rod 430 tightly fixes the tank body 400 in the support tube 200.

[0047] Start breaking: The driving motor (not shown in the figure) is started, and the rotating shaft of the driving motor drives the driving wheel to rotate through a belt (not shown in the figure), and the driving wheel drives the rotating disk 120 to rotate through the connecting shaft 140, and the rotating disk 120 drives the multiple supporting cylinders 200 to revolve around the axis of the rotating disk 120. Since the first transmission gear 180 at the bottom of the supporting cylinder 200 is meshed with the second transmission gear 190, and the second transmission gear 190 is meshed with the fixed toothed disk 150 fixedly arranged on the base 100, the fixed toothed disk 150 drives the multiple second transmission gears 190 to rotate through the rotation of the rotating disk 120, and the second transmission gear 190 drives the first transmission gear 180 to rotate, and the first transmission gear 180 drives the supporting cylinder 200 to rotate around its own axis. The multiple supporting cylinders 200 rotate around their own axes and revolve around the axis of the rotating disk 120 at the same time, so that the tank body 400 in the supporting cylinder 200 can grind and crush materials.

[0048] Reducing the material attached to the inner side wall of the tank 400: Since the second sliding teeth 210 are arranged at the bottom of the support cylinder 200, and the second sliding teeth 210 and the first sliding teeth 170 on the fixed sleeve 160 are slidably matched, when the support cylinder 200 starts to rotate, the second sliding teeth 210 will slide axially with the first sliding teeth 170, thereby pushing the support cylinder 200 to reciprocate in the axial direction, and the support cylinder 200 drives the internal tank body 400 to move axially synchronously, so that the material inside the tank body 400 is not only subjected to centrifugal force but also axial force, thereby reducing the material attached to the inner side wall of the tank body 400, and a vibration sleeve 250 is arranged axially inside the side wall of the support cylinder 200 for axial sliding. A plurality of radially extending bullets 300 are arranged on it, one end of the bullet 300 is in sliding contact with the outer periphery of the corrugated sleeve 410, and a third sliding tooth 260 is arranged at the bottom of the vibration sleeve 250, and the third sliding tooth 260 is also slidably matched with the first sliding tooth 170. When the support cylinder 200 rotates, the first sliding tooth 170 and the third sliding tooth 260 are slidably matched to drive the vibration sleeve 250 to move axially back and forth, so that the bullet 300 on the vibration sleeve 250 can hit the wave-like protrusion on the outer periphery of the corrugated sleeve 410 in the axial direction, so that the tank body 400 vibrates, further reducing the material attached to the inner side wall of the tank body 400, thereby improving the grinding and crushing effect of the material.

[0049] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
