Description

Technical Field

[0001] This invention relates to the field of tea processing, and specifically to a wet tea pulverizer. Background Technology

[0002] As is widely known, tea beverages made from tea leaves are one of the world's three major beverages. When tea is processed in large quantities in the industrial sector, it needs to be crushed. Crushing increases the surface area of ​​the tea leaves, which is conducive to the dissolution of the effective components of the tea, improving the aroma, taste and color of the tea. Crushing also breaks down the cell structure in the tea leaves, which is beneficial to the fermentation process. Furthermore, crushing makes it easier for the effective components in the tea to be dissolved by water or other solvents, thus increasing the extraction rate of the tea.

[0003] When tea leaves are wet-milled, a first and second grinding disc arranged vertically rotate relative to each other to crush the tea leaves. There is a crushing chamber between the first and second grinding discs, and a channel connected to the crushing chamber is opened at the center of each of the first and second grinding discs. There is also a material feeding device at the bottom of the crushing chamber. The material feeding device extends into the crushing chamber from the channel of the second grinding disc. The material to be crushed enters the crushing chamber from the channel on the first grinding disc. The material feeding device pushes the material to be crushed between the first and second grinding discs. The first and second grinding discs crush the material to be crushed. The crushed material flows out from the gap between the first and second grinding discs, completing the crushing process.

[0004] When the first and second grinding discs are used to crush tea leaves, they rotate relative to each other and knead the tea leaves. As a result, the tea leaves in the crushing chamber tend to clump together. Under the action of centrifugal force, the clumps stick to the edge of the crushing chamber. As the first and second grinding discs continue to rotate, they gradually grind the clumps together. However, the grinding efficiency is relatively slow, and the crushing chamber is prone to blockage, which affects the output efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a wet tea pulverizer to solve the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A wet tea pulverizer includes a drive unit and a first grinding section and a second grinding section arranged vertically. The middle of the first grinding section and the second grinding section together form a pulverizing chamber. Both the first grinding section and the second grinding section have channels communicating with the pulverizing chamber. A feeding component is also provided at the bottom of the pulverizing chamber. The feeding component extends into the pulverizing chamber through the channel on the second grinding section. The drive unit drives the feeding component and the second grinding section to rotate at a differential speed. The pulverizer also includes:

[0008] The adjustment mechanism is used to adjust the material feeding component to deflect to one side after it moves upward, so that the side wall of the deflected material feeding component contacts the inner wall of the crushing chamber.

[0009] As described above, the first grinding part includes a first grinding disc, and the second grinding part includes a second grinding disc, with the first grinding disc and the second grinding disc having the same structure.

[0010] As described above, the first grinding disc is divided into a gradient section and a gap section from the inside out. The distance between the gradient section of the first grinding disc and the gradient section of the second grinding disc is close to each other. The gradient section of the first grinding disc and the gradient section of the second grinding disc together form the inner wall of the grinding chamber. The gap section of the first grinding disc and the gap section of the second grinding disc are fitted with a clearance.

[0011] As mentioned above, multiple guide grooves are provided on the surface of the gap section between the first grinding disc and the second grinding disc. The depth of the guide grooves located in the gap section gradually decreases from the inside to the outside. The multiple guide grooves are arranged at intervals along the circumference of the first grinding disc and the second grinding disc. A clearing part is slidably provided in the guide groove on the second grinding disc by means of a spring. The clearing part slides along the groove direction of the guide groove based on the extrusion of the feeding component.

[0012] The aforementioned feeding component includes a conical block with a spherical tip facing the crushing chamber. A blocking block is located below the conical block, with its bottom end connected to the driving component. The blocking block is slidably installed in a channel on the second grinding disc, and is connected to the second grinding disc by a spring to prevent it from detaching from the second grinding disc. A clearance hole is provided at the center of the blocking block, and a vertical rod is fixedly installed at the bottom of the conical block. The vertical rod passes through the clearance hole and is slidably connected to the blocking block by a spring. The other end of the vertical rod is connected to an adjustment mechanism.

[0013] The aforementioned unblocking section includes multiple unblocking blocks, each corresponding to a guide groove. The unblocking blocks are slidably installed in the guide grooves, and the cross-section of the unblocking blocks is U-shaped.

[0014] The aforementioned vertical rod includes a fixed section and a deflection section. One end of the fixed section is connected to the adjustment mechanism, and the other end of the fixed section is hinged to the deflection section. The other end of the deflection section is connected to a conical block.

[0015] As described above, a groove is provided at one end of the deflection section near the conical block, and a sliding rod is slidably connected in the groove. The sliding rod and the groove are connected by a spring, and one end of the sliding rod is connected to the conical block.

[0016] As mentioned above, multiple material pulling grooves are provided on the gradient section of the second grinding disc. The multiple material pulling grooves are arranged at intervals along the circumference of the second grinding disc, and all material pulling grooves are inclined. A clearance groove is provided on the side wall of the conical block. A guide block is connected to the clearance groove by a spring. The shape of the guide block is adapted to the shape of the material pulling groove.

[0017] As described above, the conical block has an internal air guiding chamber, and the surface of the conical block has multiple air outlets, all of which are connected to the air guiding chamber. A one-way valve plate is also provided at the air outlet. The fixed section and the deflection section of the vertical rod are hollow inside, and a flexible pipe is provided inside the vertical rod. One end of the flexible pipe is connected to the air guiding chamber of the conical block, and the other end of the flexible pipe is connected to an air supply component, which is used to deliver gas into the flexible pipe.

[0018] The beneficial effects of the present invention are as follows: In the above technical solution, when there is a large amount of agglomerated material between the first grinding part and the second grinding part, the adjustment mechanism provided by the present invention drives the feeding member to move upward and deflect to one side, so that the side wall of the feeding member contacts the inner wall of the crushing chamber. The feeding member rotates under the action of the driving member, and the feeding member pushes the agglomerated material at the edge of the crushing chamber to temporarily leave the edge of the crushing chamber and move to the center. Then the adjustment mechanism drives the feeding member to reset, and the rotating feeding member contacts the agglomerated material at the center. Under the action of rotational force, the agglomerated material accelerates and impacts the inner wall of the crushing chamber, driving the agglomerated material to disperse, avoiding excessive agglomerated material and affecting the discharge efficiency.

[0032] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 -Appendix Figure 10 The present invention will be described in further detail below.

[0033] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "degree," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] This invention provides a wet tea pulverizer, comprising a drive unit 1 and a first grinding section 2 and a second grinding section 3 arranged vertically. The middle portions of the first grinding section 2 and the second grinding section 3 together form a pulverizing chamber 4. Both the first grinding section 2 and the second grinding section 3 have channels 5 communicating with the pulverizing chamber 4. A feeding element 6 is also provided at the bottom of the pulverizing chamber 4, extending into the pulverizing chamber 4 through the channel 5 on the second grinding section 3. The drive unit 1 drives the feeding element 6 to rotate at a differential speed with the second grinding section 3. In this embodiment, the feeding element 6 and the second grinding section 3 are arranged coaxially. The drive unit 1 preferably consists of two sets of drive units. The drive unit independently drives the feeding component 6 and the second grinding section 3 to rotate. Optionally, the drive unit 1 can also consist of a drive motor and two sets of belt drive groups. The output end of the drive motor drives a pulley with two annular grooves. The two sets of belt drive groups are used to achieve differential rotation between the feeding component 6 and the second grinding section 3. One end of the belt of one set of belt drive groups is connected to one annular groove of the pulley to receive the output of the belt drive, and the other end is connected to the feeding component 6. One end of the belt of the other set of belt drive groups is connected to the other annular groove of the pulley to receive the output of the belt drive, and the other end is connected to the second grinding section 3. Differential rotation can be achieved by having different transmission ratios between the two sets of belt drive groups. The rotation mechanism involves two sets of belt drives. When the drive motor starts operating, the second grinding section 3 and the feeding component 6 begin to rotate around their own axes under the action of the two sets of belt drives. The rotation speeds of the feeding component 6 and the second grinding section 3 are not synchronized. The differential rotation between the two sets of belt drives and the feeding component 6 under the action of the drive motor is existing technology and will not be elaborated upon here. The mechanism also includes an adjustment mechanism 7, which can be driven by the drive component 1 to rotate synchronously with the feeding component 6. The adjustment mechanism 7 is used to adjust the feeding component 6 to deflect to one side after it moves upwards. After deflection, the side wall of the feeding component 6 contacts the inner wall of the crushing chamber 4. In this embodiment... The adjusting mechanism 7 is an electrically controlled telescopic rod. The telescopic end of the electrically controlled telescopic rod is hinged to the material feeding component 6, and a torsion spring is provided at the hinge. In the initial state, the torsion spring is in a compressed state, and the material feeding component 6 is located at the bottom of the crushing chamber 4. At this time, the bottom surface of the material feeding component 6 is attached to the bottom surface of the crushing chamber 4 and cannot deflect. As the electrically controlled telescopic rod drives the material feeding component 6 to move upward, the bottom surface of the material feeding component 6 is separated from the bottom surface of the crushing chamber 4. Under the action of the torsion spring, the material feeding component 6 gradually deflects to one side until the torsion spring releases the accumulated elastic force. When the torsion spring completely releases the accumulated elastic force, the material feeding component 6 tilts to one side, and the side wall of the material feeding component 6 contacts the crushing chamber 4.

[0035] It should be noted that, in this embodiment, a weight sensor may be installed at the discharge position of the crusher. The weight sensor is used to monitor the weight of the crusher's output per minute. When the raw material supply is sufficient, but the weight of the output per minute decreases, the weight sensor sends a signal to the adjustment mechanism 7. The adjustment mechanism 7 drives the feeding component 6 to move upward and then deflect to one side (the weight sensor's monitoring of the output per minute and sending a signal to the adjustment mechanism 7 are both existing technologies and will not be described in detail below).

[0036] Specifically, when the raw material supply is sufficient, but the weight of the material output decreases per minute, it means that a blockage has occurred between the first grinding section 2 and the second grinding section 3 (this blockage does not mean a complete blockage, but rather that the gap has narrowed, resulting in a reduction in the amount of material discharged per minute). Subsequently, the weight sensor sends an electrical signal to the adjustment mechanism 7, and the linear telescopic rod of the adjustment mechanism 7 begins to extend. The linear telescopic rod, along with the material feeding component 6, extends upward into the crushing chamber 4. As the material feeding component 6 extends into the crushing chamber 4, the torsion spring gradually releases the accumulated elastic force until the material feeding component... The material feeder 6 tilts to one side, and the side wall of the material feeder 6 contacts the inner wall of the crushing chamber 4. As the drive unit 1 drives, the material feeder 6 and the second grinding part 3 rotate at different speeds. The material feeder 6 pushes the clumps of material at the edge of the crushing chamber 4 away from the edge of the crushing chamber 4 and moves them to the center of the crushing chamber 4. Then, the linear telescopic rod drives the material feeder 6 to reset. The rotating material feeder 6 contacts the clumps of material at the center. Under the action of rotational force, the clumps of material accelerate and collide with the inner wall of the crushing chamber 4, causing the clumps of material to disperse and avoid excessive clumps that would affect the discharge efficiency.

[0037] It should be noted that in existing disc grinders (specifically referring to models that grind materials using two grinding discs arranged vertically), the surfaces of the two grinding discs are not smooth planes to facilitate material discharge. Multiple guide grooves exist on the surface of the grinding discs. However, as grinding progresses, the material between the two grinding discs gradually increases (this includes both pre-grinding and post-grinding materials), gradually filling the guide grooves. If the material in the guide grooves cannot be discharged in time, it is easily compacted under the pressure of the two grinding discs, affecting the equipment's discharge efficiency. Furthermore, as the material between the two grinding discs increases, a large amount of material tends to adhere to the two grinding discs, reducing the coefficient of friction between them and affecting the grinding efficiency.

[0038] In another embodiment of the present invention, the first grinding part 2 includes a first grinding disc 21, and the second grinding part 3 includes a second grinding disc 31. The structures of the first grinding disc 21 and the second grinding disc 31 are basically the same (the structure of the first grinding disc 21 will be described in detail later, and the structure of the second grinding disc 31 will not be repeated). The first grinding disc 21 is divided into a circular gradient section 211 and an annular gap section 212 from the inside to the outside. The gradient sections 211 of the first grinding disc 21 and the second grinding disc 31 are close to each other. That is, according to the direction of the first grinding disc 21 from the inside to the outside, the distance between the gradient sections 211 on the first grinding disc 21 and the second grinding disc 31 gradually decreases. The gradient sections 211 of the first grinding disc 21 and the second grinding disc 31 together constitute the inner wall of the crushing chamber 4. The gap section 212 of the first grinding disc 21 and the gap section 212 of the second grinding disc 31 are in clearance fit. The material is ground into powder through the gap section 212 between the first grinding disc 21 and the second grinding disc 31.Multiple guide grooves 8 are provided on the near end faces of the gap section 212 between the first grinding disc 21 and the second grinding disc 31. These guide grooves 8 extend through the entire gap section 212, thus connecting the grinding chamber 4 between the first grinding disc 21 and the second grinding disc 31 to the outside. The depth of the guide grooves 8 located in the gap section 212 gradually decreases from the inside to the outside (here, "from the inside to the outside" refers to the direction from the transition section 211 to the gap section 212). Multiple guide grooves 8 are spaced apart circumferentially along the first grinding disc 21 and the second grinding disc 31. Each guide groove 8 has a spring-loaded slidable drainage mechanism. Part 9, the axis of the spring is aligned with the radial direction of the second grinding disc 31. The unblocking part 9 slides along the groove direction of the guide groove 8 based on the extrusion of the feeding member 6. The unblocking part 9 includes multiple unblocking blocks 91, each corresponding to one of the guide grooves 8. The unblocking blocks 91 are slidably installed within the guide grooves 8. (Note that the unblocking blocks 91 are connected to the guide grooves 8 by springs; these springs are the same springs connecting the unblocking part 9 and the guide grooves 8). When the spring is not under force, one end of the unblocking block 91 extends into the grinding chamber 4, and the end of the unblocking block 91 within the grinding chamber 4 is arc-shaped (in this embodiment). The cross-sectional shape of the unblocking block 91 is preferably U-shaped. It should be noted that the U-shaped cross-section of the unblocking block 91 is not constant; the cross-sectional shape of the unblocking block 91 is determined based on the shape of the guide groove 8. The feeding component 6 includes a conical block 61 with a spherical tip, and the conical block 61 faces into the crushing chamber 4. A blocking block 62 is disposed below the conical block 61. The blocking block 62 is slidably installed in the channel 5 on the second grinding disc 31. The blocking block 62 and the second grinding disc 31 are connected by a spring, which is used to prevent the blocking block 62 from disengaging from the second grinding disc 31 (it can be connected to the channel 5 on the second grinding disc 31). A groove is provided on the side wall of channel 5, and the blocking block 62 slides along the groove (the movement distance of the blocking block 62 is limited by the groove). A clearance hole 64 is provided at the center of the blocking block 62. A vertical rod 63 is fixedly installed at the bottom of the conical block 61. The vertical rod 63 passes through the clearance hole 64 and is slidably connected to the blocking block 62 (for example, a rubber sleeve is added to the inner wall of the clearance hole 64. When the vertical rod 63 moves upward, the blocking block 62 moves upward synchronously through the rubber sleeve under the action of friction). The other end of the vertical rod 63 is connected to the adjustment mechanism 7. When the adjustment mechanism 7 drives the material pusher 6 to move upward, the action of the material pusher 6 is as follows:

[0039] Step 1: The cone-shaped block 61, the barrier block 62, and the vertical rod 63 move upwards synchronously toward the inside of the crushing chamber 4;

[0040] Step 2: Block 62 stops moving due to being pulled by the spring, while cone block 61 and vertical rod 63 continue to move toward the inside of crushing chamber 4;

[0041] Furthermore, the vertical rod 63 includes a fixed section 631 and a deflection section 632. One end of the fixed section 631 is connected to the adjustment mechanism 7, and the other end of the fixed section 631 is hinged to the deflection section 632. The other end of the deflection section 632 is connected to the conical block 61. In this embodiment, the adjustment mechanism 7 is still selected as an electrically controlled telescopic rod, but the telescopic end of the electrically controlled telescopic rod is fixedly connected to the fixed section 631.

[0042] Specifically, when the output decreases, the weight sensor sends an electrical signal to the adjustment mechanism 7, causing the electrically controlled telescopic rod of the adjustment mechanism 7 to extend. The telescopic rod first moves the entire vertical rod 63, the conical block 61, and the obstruction block 62 upwards together. When the obstruction block 62 reaches its furthest position, it stops moving. At this point, the obstruction block 62 protrudes from the bottom surface of the crushing chamber 4. Preferably, the top surface dimension of the obstruction block 62 should be similar to the bottom dimension of the conical block 61 to prevent a large amount of material from accumulating below the conical block 61 and affecting its normal reset. Subsequently, as the telescopic rod continues to extend, the conical block 61 and the entire vertical rod 63 continue to move upwards toward the interior of the crushing chamber 4 until the hinge position of the fixed section 631 and the deflection section 632 of the vertical rod 63 leaves the obstruction block 62. This causes the torsion spring connecting the fixed section 631 and the deflection section 632 to lose its restraining force and release. The accumulated elastic force causes the deflection section 632 to deflect relative to the fixed section 631. Subsequently, the driving component 1 continues to drive the material feeding component 6 to rotate differentially with the second grinding disc 31. The conical block 61 on the material feeding component 6 pushes the clumps of material at the edge of the crushing chamber 4 away from their original position, preventing excessive clumps of material at the edge of the crushing chamber 4 from affecting the normal discharge of material. Furthermore, as the conical block 61 rotates, the tip of the conical block 61 will squeeze the unblocking block 91. At this time, the spring connecting the unblocking block 91 is compressed, accumulating elastic potential energy. When the conical block 61 leaves the corresponding unblocking block 91, the spring releases the accumulated elastic force, pushing the unblocking block 91 to reset along the guide groove 8, realizing that the unblocking block 91 slides back and forth along the groove of the guide groove 8 on the gap section 212. The moving unblocking block 91 unblocks the material in the guide groove 8, preventing the guide groove 8 on the gap section 212 from becoming blocked and affecting the discharge speed.

[0043] It should be noted that the unblocking part 9 is only provided on the lower grinding device. In this embodiment, the unblocking part 9 is provided in the guide groove 8 on the second grinding disc 31. Since the grinding surface of the upper first grinding disc 21 faces downward, the agglomerated material is not easy to accumulate on the grinding surface of the first grinding disc 21 under the action of gravity. However, the grinding surface of the second grinding disc 31 faces upward, so the agglomerated material is more likely to accumulate on the grinding surface of the second grinding disc 31. Therefore, the unblocking part 9 can be installed on the second grinding disc 31. In addition, in this embodiment, a frame for collecting the crushed material is also provided on the outside of the first grinding part 2 and the second grinding part 3. That is, when the first grinding part 2 and the second grinding part 3 are finished, a frame for collecting the crushed material is provided on the outside of the frame. After the materials are crushed in pairs, the crushed materials enter the frame, making it convenient for workers to collect them. The first grinding part 2 and the second grinding part 3 can be separated from each other, allowing the operator to open the crushing chamber 4 and hinge the first grinding part 2 and the second grinding part 3 together. Preferably, a locking mechanism is also provided on the outside of the first grinding part 2 or the second grinding part 3. The locking mechanism is used to lock the first grinding part 2 and the second grinding part 3 to prevent the first grinding part 2 and the second grinding part 3 from opening when crushing materials. The locking mechanism can be a common locking mechanism such as a threaded lock or a magnetic lock, which is existing technology and will not be described in detail here.

[0044] In existing grinding chambers 4, the space is often large, so the tilting deflection section 632 with the conical block 61 cannot reach the edge of the grinding chamber 4. Therefore, even if the rotation speed of the feeding component 6 is fast, it is impossible to push the clumps of material at the edge of the grinding chamber 4 away from the edge of the grinding chamber 4. In another embodiment of the present invention, a plurality of material pulling grooves 81 are provided on the gradient section 211 of the second grinding disc 31. The plurality of material pulling grooves 81 are arranged at intervals along the circumference of the second grinding disc 31, and the material pulling grooves 81 are all inclined. A sink trough 633 is provided at the end of the deflection section 632 near the conical block 61, and a sliding rod 6 is slidably connected in the sink trough 633. 34. The slide rod 634 and the sink 633 are connected by a spring. One end of the slide rod 634 is connected to the conical block 61. A clearance groove is provided on the side wall of the conical block 61. A guide block 616 is connected to the clearance groove by a spring. The shape of the guide block 616 is adapted to the shape of the material pulling groove 81. The depth of the material pulling groove 81 gradually becomes shallower from the inside to the outside (this direction from the inside to the outside is also along the radial direction of the second grinding disc 31). When the guide block 616 slides along the groove direction of the material pulling groove 81 and slides to the farthest end of the material pulling groove 81, the depth of the material pulling groove 81 is the shallowest, which makes it easy for the guide block 616 to disengage from the material pulling groove 81.

[0045] Specifically, after the deflection section 632 deflects from the fixed section 631, the deflection section 632, carrying the conical block 61, deflects towards the surface of the second grinding disk 31, causing the guide block 616 on the conical block 61 to be perpendicular to the surface of the second grinding disk 31. Subsequently, as the driving component 1 drives the feeding component 6 to rotate differentially with the second grinding disk 31, the conical block 61 and the second grinding disk 31 rotate relative to each other. During the rotation, the guide block 616 on the conical block 61 rotates synchronously with the conical block 61, and the guide block 616 will insert into the surface of the second grinding disk 31. Inside the material-pulling groove 81, as the second grinding disc 31 rotates, the guide block 616 slides along the groove of the material-pulling groove 81, thereby pulling the conical block 61 to slide along the material-pulling groove 81 until the conical block 61 abuts against the inner wall of the crushing chamber 4 (at this time, under the traction of the conical block 61, the slide rod 634 slides along the groove of the settling trough 633, the spring connecting the slide rod 634 is stretched, and the guide block 616 moves to the farthest end of the material-pulling groove 81). Then, as the conical block 61 and the second grinding disc 31 continue to rotate relative to each other, the guide block... The spring of 616 contracts under compression, causing the guide block 616 to disengage from the material pulling groove 81. Then, the spring connecting the slide rod 634 resets, causing the slide rod 634 to slide along the groove of the settling trough 633. The slide rod 634, carrying the conical block 61, moves away from the edge of the crushing chamber 4 towards the center of the crushing chamber 4. As the conical block 61 moves, it carries the agglomerated material away from the edge of the crushing chamber 4. Then, as the feeding component 6 continues to rotate, each time the conical block 61 passes through a material pulling groove 81, it dissolves the agglomerated material at the edge of the crushing chamber 4. The material is pulled towards the center, and through the repeated movements of the cone block 61, the cone block 61 pushes a large amount of agglomerated material away from the edge of the crushing chamber 4, causing a large amount of agglomerated material to accumulate near the center of the crushing chamber 4. Finally, the linear telescopic rod drives the feeding component 6 to reset. After resetting, the cone block 61 rotates under the action of the driving component 1. The rotating cone block 61 contacts the agglomerated material at the center. Under the action of rotational force, the agglomerated material accelerates and impacts the inner wall of the crushing chamber 4, causing the agglomerated material to disperse and avoid excessive agglomerated material, which would affect the discharge efficiency.

[0046] To further enhance discharge efficiency, the conical block 61 has an internal air guide chamber 611, and its surface has multiple air outlets 612, all of which are connected to the air guide chamber 611. A one-way valve plate 613 is also installed at each air outlet 612. The one-way valve plate 613 prevents material from entering the air outlet 612 from causing blockage, but allows gas from the air guide chamber 611 to pass through the one-way valve plate 613 into the crushing chamber 4 (the one-way valve plate 613 allows gas to pass through normally). (The above is existing technology and will not be described in detail later.) The fixed section 631 and the deflection section 632 of the vertical rod 63 are hollow inside. A flexible pipe 614 is provided inside the vertical rod 63. One end of the flexible pipe 614 is connected to the air guide cavity 611 of the cone block 61. The other end of the flexible pipe 614 is connected to an air supply component 615. The air supply component 615 is used to deliver gas into the flexible pipe 614. In this embodiment, the air supply component 615 can be selected as an air pump. The air pump is connected to the flexible pipe 614 and delivers gas into the flexible pipe 614.

[0047] Specifically, when the conical block 61 pushes the agglomerated material away from the edge of the crushing chamber 4, the air supply component 615 starts working simultaneously. The air pump of the air supply component 615 inputs gas into the flexible pipe 614. The gas enters the air guide chamber 611 of the conical block 61 through the flexible pipe 614 and is ejected from the multiple air outlets 612 on the conical block 61. The airflow impacts the surface of the second grinding disc 31, preventing the material from agglomerating on the surface of the second grinding disc 31.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
