[0047] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0048] A quinoa grinding device and a method of use according to an embodiment of the present application are described below in conjunction with the accompanying drawings.

[0049] like Figures 1 - 6 As shown, a quinoa grinding device and a method of use according to an embodiment of the present application may include a base plate (1), an equipment box (2), a driving device (3), a conveying device (4), a feed port (5), a first grinding device (6), a discharge port (7), a second grinding device (8) and a plurality of hole cleaning devices (9).

[0050] It is understandable that the core structure of the quinoa grinding device is constructed based on the base plate (1). The base plate (1) serves as a bearing base, and the device box (2) is fixed on the top of the base plate (1). The driving assembly (31) of the driving device (3) is rotatably mounted in the internal cavity of the device box (2) through a bearing, forming a power center.

[0051] The conveying assembly (41) of the conveying device (4) is arranged at the upper end of one side of the equipment box (2), and its input end is connected to the driving assembly (31) through a coupling to achieve transmission connection, thereby obtaining rotational power. The feed inlet (5) is welded to the side wall of the equipment box (2), and its opening is directly opposite to the upper part of the receiving area of the conveying assembly (41), so as to ensure that the quinoa falls vertically into the conveying assembly (41).

[0052] The first grinding assembly (61) of the first grinding device (6) is connected to the output end of the transmission assembly (41) and receives continuous power from the driving assembly (31). The end of the first grinding assembly (61) extends to form a discharge end, which is connected to the discharge port (7) through a flange, and the connecting plate (613)

[0053] As a component of the first grinding assembly (61), it is welded to its outer side wall and directly constitutes the discharge end structure. The hole cleaning assemblies (91) of the plurality of hole cleaning devices (9) are movably arranged on the surface of the connecting plate (613) through guide grooves for cleaning holes.

[0054] The second grinding device (8) is fixed to the right side of the base plate (1) through an independent support frame (81). A linkage assembly (82) is installed inside the support frame (81), and the input end of the linkage assembly (82) extends into the equipment box (2) and is transmission-connected to the power output end of the drive assembly (31). The main body of the second grinding assembly (83) is a collection box (831), which is rotatably installed on the support frame (81) through a rotating shaft, and the rotating shaft is transmission-connected to the output end of the linkage assembly (82). The top of the collection box (831) is covered with a box cover (832), and a circular inlet (834) is opened in the center of the box cover (832), and its position is precisely aligned with the upper discharge port (7) to ensure that the material falls vertically into the collection box (831).

[0055] Workflow Description:

[0056] 1. Power startup: The drive assembly (31) rotates inside the equipment box (2) and outputs power to two paths simultaneously.

[0057] 2. Conveying and primary grinding: One path of power drives the conveyor assembly (41) to rotate, conveying the quinoa fed into the feeding port (5) to the first grinding assembly (61); after the material is pulverized in the first grinding assembly (61), it is discharged from the discharging port (7) through the channel of the connecting plate (613).

[0058] 3. Preparation for secondary grinding: The other path of power is transmitted through the linkage assembly (82) to drive the collection box (831) to rotate around the axis on the support frame (81).

[0059] 4. Fine grinding: The initially pulverized material discharged from the discharging port (7) vertically falls into the inlet (834) of the box cover (832) and enters the high-speed rotating collection box (831) for secondary grinding.

[0060] 5. Hole cleaning operation: When the discharge channel of the connecting plate (613) is blocked, manually operate the hole cleaning assembly (91) to move on the surface of the connecting plate (613) to perform dredging.

[0061] In an embodiment of the present application, as Figures 1 - 6 shown, the drive assembly (31) includes a drive motor (311), a first connecting shaft (312), a first gear (313), a second connecting shaft (314), a second gear (315), a third gear (316), a third connecting shaft (317), and a fourth gear (318).

[0062] It can be understood that the drive motor (311) is used as a power source and is fixed to the inner bottom plate of the equipment box (2) by bolts, and its output shaft is rigidly connected to the first connecting shaft (312) through a coupling.

[0063] Both ends of the first connecting shaft (312) are rotatably installed on the left and right side walls of the equipment box (2) through deep groove ball bearings to ensure axial positioning and radial support; the first gear (313) is fixedly sleeved in the middle of the shaft body and rotates synchronously with the motor.

[0064] The second connecting shaft (314) is parallel to the first connecting shaft (312) and is rotatably arranged in the middle of the equipment box (2) through bearings. The third gear (316) and the second gear (315) are fixedly sleeved on the shaft body from left to right in sequence.

[0065] The third gear (316) is located on the left side and forms an external meshing drive with the first gear (313): when the first connecting shaft (312) drives the first gear (313) to rotate clockwise, the third gear (316) rotates counterclockwise, driving the second connecting shaft (314) to rotate counterclockwise synchronously.

[0066] The third connecting shaft (317) is parallel to the first two shafts and is rotatably mounted on the right side wall of the equipment box (2) via a bearing. The shaft body is fixedly sleeved with a fourth gear (318).

[0067] The second gear (315) is located on the right side of the second connecting shaft (314) and is externally meshed with the fourth gear (318): when the second connecting shaft (314) rotates counterclockwise, the second gear (315) drives the fourth gear (318) to rotate clockwise, driving the third connecting shaft (317) to rotate clockwise synchronously.

[0068] It should be noted that: all the connections between the connecting shafts and the equipment box (2) use sealed bearing seats to prevent dust from entering and affecting the rotation accuracy; the gear meshing clearance is adjusted by adjusting the axis spacing to ensure smooth transmission.

[0069] The gear adopts an involute spur tooth structure, the tooth surface is quenched to improve wear resistance, and the fixed sleeve is keyed or interference fit to ensure the transmission of power without sliding.

[0070] In one embodiment of the present application, Figures 1 - 6 As shown, the conveying assembly (41) includes an outer sleeve (411), a conveying roller (412) and a fixed support frame (413).

[0071] It can be understood that the outer sleeve (411) is a hollow cylindrical metal shell, which is fixed to the upper end of the side wall of the equipment box (2) by bolts, and its axis extends in the horizontal direction. The outer sleeve (411) is provided with a feed opening at the left end close to the feed opening (5), and the opening size is slightly larger than the discharge cross section of the feed opening (5), so as to ensure that the quinoa material falls into the sleeve without hindrance.

[0072] The fixed support frame (413) is an L-shaped metal bracket, one end of which is fixedly connected to the middle outer wall of the outer sleeve (411) by bolts, and the other end is fixed to the top of the bottom plate (1) by expansion bolts to form a triangular support structure to prevent the outer sleeve (411) from shaking during the transmission process.

[0073] The conveying roller (412) is a cylindrical roller body with spiral blades on the surface, and is rotatably installed inside the outer sleeve (411) through deep groove ball bearings at both ends, and the axis of the roller body coincides with the axis of the outer sleeve (411).

[0074] The right end of the conveying roller (412) extends out of the outer sleeve (411) and is connected to the left end of the third connecting shaft (317) through a coupling. When the third connecting shaft (317) rotates clockwise under the drive of the driving assembly (31), the conveying roller (412) rotates clockwise synchronously, and the spiral blades on its surface push the material to move to the right (i.e., the direction of the first grinding device (6)).

[0075] 1. Feeding stage: The quinoa grains to be ground fall from the feeding port (5) on the side wall of the equipment box (2), enter the inside of the sleeve through the left-end feeding opening of the outer sleeve (411), and accumulate on the surface of the conveying roller (412).

[0076] 2. Conveying stage: The conveying roller (412) continuously rotates under the drive of the third connecting shaft (317). When the spiral blades on its surface come into contact with the material, the material is conveyed axially to the right along the outer sleeve (411) through the frictional force and mechanical pushing action. The pitch and angle of the spiral blades are designed according to the size of the quinoa grains to ensure uniform conveying speed and no slipping.

[0077] 3. Guiding stage: The right-end outlet of the outer sleeve (411) is docked with the feeding end of the first grinding device (6). After the material is pushed by the conveying roller (412) to the end of the sleeve, it directly falls into the grinding area of the first grinding assembly (61).

[0078] In an embodiment of the present application, as Figures 1 - 6 shown, the first grinding assembly (61) further includes a rolling roller (611) and rolling teeth (612).

[0079] It can be understood that the rolling roller (611) is a cylindrical metal roller body, and its axis coincides completely with the axis of the conveying roller (412). It is coaxially fixed to the conveying roller (412) through key connection to form an "integrated conveying - grinding" shaft system. When the conveying roller (412) rotates driven by the third connecting shaft (317), the rolling roller (611) rotates synchronously at the same speed.

[0080] The outer sleeve (411) serves as a common housing for conveying and grinding. Its internal space is divided into two sections: the front section is the material conveying area (corresponding to the conveying roller (412)), and the rear section is the grinding area (corresponding to the rolling roller (611) and the rolling teeth (612)). The two are connected in series through the same axis.

[0081] Convex teeth (6111) are evenly distributed along the circumference of the roller surface of the rolling roller (611). The convex teeth are trapezoidal structures with a height of 5 - 10 mm, and their tips point to the tangential direction of the rotation of the rolling roller (611).

[0082] The rolling teeth (612) are comb-shaped protrusions fixed on the inner wall of the outer sleeve (411), corresponding to the convex teeth (6111) one by one and distributed in a staggered manner to form a grinding gap (1 - 3 mm). When the rolling roller (611) rotates clockwise, the convex teeth (6111) and the rolling teeth (612) form a combined shearing - rolling action:

[0083] Shearing action: When the material particles enter the gap between the convex teeth (6111) and the rolling teeth (612), they are torn and broken by the relative movement of the two;

[0084] Rolling action: Larger particles are squeezed by the convex teeth (6111) against the inner wall of the outer sleeve (411), and crushing is achieved through the rigid support of the rolling teeth (612).

[0085] The connecting plate (613) is an annular metal plate, bolt-fixed to the outer wall of the end of the outer sleeve (411), and its center is aligned with the axis of the rolling roller (611). A plurality of discharge through-holes (614) are radially provided on the connecting plate (613). The through-holes are circular or waist-shaped, with a diameter of 2 - 5 mm (set according to the target grinding particle size), and are equally spaced along the circumference and communicate with the inside of the outer sleeve (411).

[0086] Under the action of the rotational centrifugal force of the rolling roller (611), the ground material is thrown towards the inner wall of the outer sleeve (411). After being broken through the grinding gap to be smaller than the aperture of the discharge through-hole (614), it falls through the through-hole into the feeding port (7) outside the connecting plate (613). Particles that do not meet the particle size requirements continue to stay in the grinding area for repeated rolling until they are discharged through the through-hole.

[0087] The bearing installation part of the rolling roller (611) and the outer sleeve (411) uses a double-row tapered roller bearing to bear the radial load and axial force during the grinding process; the rolling teeth (612) are made by surfacing with wear-resistant electrodes, and the surface hardness is ≥HRC55 to extend the service life.

[0088] The hole pitch of the discharge through-hole (614) is the same as the circumferential pitch of the convex teeth (6111) to ensure that the material is evenly discharged within one rotation of the roller body, avoiding local blockage. An annular diversion groove is provided at the connection between the connecting plate (613) and the outer sleeve (411) to guide the material to converge towards the through-hole.

[0089] In one embodiment of the present application, as Figures 1 - 6 shown, the linkage assembly (82) includes a first pulley (821), a second pulley (822), a belt (823), a worm (824), a mounting seat (825), and a worm gear (826).

[0090] It can be understood that the first pulley (821) is fixedly sleeved on the right end of the second connecting shaft (314) of the drive assembly (31) through a key connection and rotates counterclockwise synchronously with the second connecting shaft (314).

[0091] The second pulley (822) is rotatably mounted on the right outer wall of the equipment box (2) through a deep groove ball bearing, and its axis is parallel to the axis of the second connecting shaft (314). The belt (823) is a synchronous belt, tensioned and sleeved in the pulley grooves of the first pulley (821) and the second pulley (822) to form a first-stage belt drive, transmitting the rotational power of the second connecting shaft (314) to the second pulley (822).

[0092] The worm (824) is a cylindrical worm. Its left end is coaxially and fixedly connected to the second pulley (822) through a flange. Its right end penetrates the vertical side plate of the support frame (81) and is rotatably connected to the support frame (81) through a tapered roller bearing, ensuring that the worm (824) can rotate around its own axis.

[0093] The mounting seat (825) is a hollow cylindrical structure and is rotatably arranged on the top of the support frame (81) through a thrust ball bearing. Its axis is perpendicular to and intersects with the axis of the worm (824). The worm gear (826) is fixedly sleeved on the outer peripheral wall of the mounting seat (825) to form a worm and worm gear pair in perpendicular meshing with the worm (824).

[0094] When the second pulley (822) drives the worm (824) to rotate clockwise, the spiral teeth of the worm (824) push the worm gear (826) to rotate counterclockwise. Due to the large transmission ratio characteristic of the worm and worm gear transmission (the number of worm heads is 1, and the number of worm gear teeth is 30 - 50), the high-speed small torque can be converted into low-speed large torque to drive the mounting seat (825) to rotate smoothly.

[0095] 1. Belt drive stage:

[0096] The second connecting shaft (314) of the drive assembly → the first pulley (821) → the belt (823) → the second pulley (822)

[0097] (Realize the power transmission from the inside to the outside of the equipment box (2) and avoid the direct exposure of gears)

[0098] 2. Worm and worm gear drive stage:

[0099] The second pulley (822) → the worm (824) → the worm gear (826) → the mounting seat (825)

[0100] (Change the power direction through orthogonal transmission and use the self-locking characteristic of the worm gear to prevent the collection box (831) from reversing during the grinding process)

[0101] A dust-proof sealing ring is provided at the bearing connection of the worm (824) and the support frame (81) to prevent grinding dust from entering the bearing; the worm gear (826) and the mounting seat (825) are fixed doubly by a positioning pin and a bolt to ensure no circumferential sliding.

[0102] In an embodiment of the present application, as Figures 1 - 6 shown, the collection box (831) of the second grinding assembly (83) is fixedly connected to the top of the mounting seat (825). An opening cover (835) is also hinged on the box cover (832). A rolling ball rod (833) is also provided on the box cover (832). The rolling ball rod (833) has a rod body that is threadedly engaged with the box cover (832).

[0103] It is understandable that the collection box (831) is a cylindrical metal container with an open upper end. The center of the bottom is fixedly connected to the top plane of the mounting seat (825) by bolts to ensure that the two rotate coaxially. When the worm gear (826) of the linkage assembly (82) drives the mounting seat (825) to rotate counterclockwise, the collection box (831) synchronously rotates at a high speed around the vertical axis, forming a centrifugal force field.

[0104] The box cover (832) is a circular metal plate. A circular through-hole is reserved in the center of the box cover (832) as the inlet (834), which is vertically aligned with the blanking port (7) to ensure that the material after the first grinding directly falls into the collection box (831).

[0105] The opening cover (835) is a semi-circular openable part on the box cover (832). After the grinding is completed, the opening cover (835) can be lifted separately, which is convenient for the operator to take out the grinding finished product from above without disassembling the entire box cover (832).

[0106] The rolling ball rod (833) includes a spherical rolling head (made of cemented carbide) at the lower end and a threaded rod body at the upper end. The threaded rod body is matched with the threaded hole in the center of the box cover (832) to form a threaded transmission pair. By rotating the rolling ball rod (833) counterclockwise, it can extend downward into the interior of the collection box (831); rotating clockwise will cause it to withdraw upward.

[0107] When the collection box (831) rotates, the material is thrown towards the box wall under the action of centrifugal force. At this time:

[0108] Impact grinding: Larger particles impact the box wall or the spherical head of the rolling ball rod (833) and are broken by the impact force;

[0109] Friction grinding: Sliding friction occurs between particles and between particles and the surface of the spherical head, further refining the particle size;

[0110] Shearing grinding: When the spherical head rotates with the collection box, a speed difference is formed between its movement track and the material flow direction, generating a shearing effect.

[0111] The operator can adjust the extending length of the rolling ball rod (833) through the thread according to the target grinding particle size:

[0112] The greater the depth, the higher the stirring and impact frequency of the spherical head on the material, which is suitable for rough grinding;

[0113] The smaller the depth, the material mainly relies on centrifugal force to impact the box wall, which is suitable for fine grinding.

[0114] It should be noted that: an annular convex rib is provided on the inner wall of the collection box (831), forming an intersecting grinding path with the spherical head of the rolling ball rod (833), avoiding the material from rotating synchronously with the box wall and losing the grinding effect.

[0115] A sealing ring is provided at the hinge joint between the lid (832) and the collection box (831) to prevent dust from overflowing during the grinding process; a rubber pad is embedded in the edge of the open lid (835), and a seal is formed when locked by a buckle to ensure the safety of the device operation.

[0116] In an embodiment of the present application, as Figures 1 - 6 shown, the hole cleaning assembly (91) includes an operation plate (911), a rotating rod (912), a first helical gear (913), a threaded rod (914), a second helical gear (915), a bearing seat (916) and two cleaning plates (918).

[0117] It can be understood that the operation plate (911) is a rectangular plate, and is pluggably embedded in the corresponding mounting hole position on the outside of the connecting plate (613) through a slot, ensuring that the central axis of the operation plate (911) coincides with the central axis of the discharge through hole (614).

[0118] Each discharge through hole (614) corresponds to an independent hole cleaning assembly (91), realizing precise maintenance of "one hole, one cleaning", and avoiding overall disassembly of the grinding device during shutdown.

[0119] The rotating rod (912) is a vertically arranged cylindrical rod, and is rotatably installed in the vertical through hole at the top of the operation plate (911) through a deep groove ball bearing. The top of the rod extends outside the operation plate and is provided with a knob or a handle for easy manual rotation by the operator.

[0120] The first helical gear (913) is fixedly connected to the bottom end of the rotating rod (912), and its tooth surface forms an angle of 45° with the horizontal direction; the threaded rod (914) is a horizontally arranged metal rod, and trapezoidal threads with opposite helix directions are processed at both ends (one end is right-handed and the other end is left-handed), and a second helical gear (915) is fixedly sleeved in the middle, forming a helical gear pair that is vertically meshed with the first helical gear (913).

[0121] The bearing seats (916) are two symmetrically arranged U-shaped brackets, and both ends of the threaded rod (914) are respectively installed in the bearing seats (916) through deep groove ball bearings to ensure the coaxiality and stability of the threaded rod (914) during rotation.

[0122] Horizontal through grooves (917) are opened at the left and right ends of the operation plate (911), and the width of the through groove matches the thickness of the cleaning plate (918) (a gap of 0.5 - 1 mm is reserved), allowing the cleaning plate (918) to slide horizontally along the through groove.

[0123] The two cleaning plates (918) are rectangular thin plates, with internal threaded holes machined on the inner side to cooperate with the threaded sections of the threaded rods (914), and are respectively screwed onto the left and right ends of the threaded rods (914). When the threaded rod (914) rotates clockwise, due to the opposite thread directions at both ends, the two cleaning plates (918) slide towards each other along the through slot (917), and their front ends insert into the discharge through hole (614) to scrape off the blocked material particles; when the threaded rod rotates counterclockwise, the cleaning plates (918) slide away from each other and withdraw from the discharge through hole.

[0124] The front end of the cleaning plate (918) is wedge-shaped and fits the inner wall contour of the discharge through hole (614), ensuring that the adhered material on the hole wall can be effectively removed during sliding while avoiding damaging the edge of the through hole.

[0125] 1. Install the operation plate: When it is necessary to clean a certain discharge through hole (614), insert the corresponding operation plate (911) along the slot into the connecting plate (613) until the inner side of the operation plate abuts against the outer edge of the discharge through hole.

[0126] 2. Rotate the rotating rod: The operator rotates the rotating rod (912) clockwise, and through the meshing transmission of the first helical gear (913) and the second helical gear (915), drives the threaded rod (914) to rotate clockwise.

[0127] 3. Feed the cleaning plate: When the threaded rod (914) rotates, the cleaning plates (918) at both ends slide towards each other, pass through the through slot (917) and enter the discharge through hole (614), and remove the blockage by mechanical pushing and scraping.

[0128] 4. Reverse the feed: After the cleaning is completed, rotate the rotating rod (912) counterclockwise, the cleaning plates (918) slide away from each other and withdraw from the through hole, and then pull out the operation plate (911) to complete a single through hole cleaning operation.

[0129] It should be noted that there are limit holes on the connecting plate 613 for limiting the cleaning component (91) when it is not in use.

[0130] In an embodiment of the present application, as Figures 1 - 6 shown, the usage method of the quinoa grinding device includes the following steps:

[0131] Step 1: Start the drive motor (311)

[0132] The core power source driving motor (311) of the driving device (3) is powered on and started, and its output shaft drives the first connecting shaft (312) to rotate clockwise through the coupling. The first gear (313) on the first connecting shaft (312) rotates synchronously, and drives the second connecting shaft (314) to rotate counterclockwise through the meshing third gear (316), and then drives the third connecting shaft (317) to rotate clockwise through the meshing of the second gear (315) and the fourth gear (318), thereby completing the power initialization of the driving component (31).

[0133] Step 2: Put the material into the feed port (5)

[0134] The operator pours the quinoa particles to be ground into the equipment box (2) from the feed port (5) on the side wall, with the lower end opening of the feed port (5) facing the left end feed opening of the outer sleeve (411) of the conveying component (41), ensuring that the material falls vertically onto the surface of the conveying roller (412) without splashing or accumulation.

[0135] Step 3: The conveyor roller (412) drives the material to be transported

[0136] The conveying roller (412) is connected to the left end of the third connecting shaft (317) through a coupling and rotates clockwise with the third connecting shaft (317). The spiral blades on the surface of the conveying roller (412) push the material to move axially to the right along the outer sleeve (411) until it enters the grinding area of the first grinding device (6).

[0137] Step 4: Initial grinding process

[0138] The rolling roller (611) of the first grinding assembly (61) is fixed coaxially with the conveying roller (412), and thus rotates clockwise synchronously, and the convex teeth (6111) on the roller surface and the rolling teeth (612) on the inner wall of the outer sleeve (411) form a staggered shear gap. After the material enters the grinding area, the convex teeth (6111) rotate with the rolling roller (611), squeezing the particles onto the surface of the rolling teeth (612), and crushing them through rolling and shearing to achieve the initial grinding.

[0139] Step 5: Discharging of the primary grinding material

[0140] The crushed material is thrown toward the inner wall of the outer sleeve (411) under the centrifugal force of the rolling roller (611), and particles with a particle size smaller than the hole size of the discharge through hole (614) on the connecting plate (613) fall into the outer discharge port (7) through the through hole and are transported downward along the inclined pipeline.

[0141] Step 6: The material falls into the collection box (831)

[0142] The outlet of the blanking port (7) is exactly aligned with the inlet (834) of the cover (832) of the second grinding device (8). The material vertically drops through the blanking port and enters the interior of the collection box (831) through the inlet (834), completing the connection of the two grinding processes.

[0143] Step 7: Realization of secondary fine grinding

[0144] The first pulley (821) of the linkage component (82) rotates counterclockwise along with the second connecting shaft (314), drives the second pulley (822) to rotate synchronously through the belt (823), and further drives the worm (824) to rotate. The worm (824) meshes with the worm gear (826), transmits the rotational power to the mounting seat (825), and enables the collection box (831) fixed on the top of the mounting seat to continuously rotate around the vertical axis. The material in the collection box (831) is thrown towards the box wall under the action of centrifugal force, collides and rubs against the spherical head of the rolling ball rod (833) and the box wall, realizing secondary fine grinding. The rolling ball rod (833) can adjust the insertion depth through thread fit to adapt to different grinding requirements.

[0145] Step 8: Cleaning operation of the discharge through hole (614)

[0146] When it is found that the discharge through hole (614) is blocked, the operator inserts the operation board (911) of the corresponding hole cleaning component (91) into the installation groove of the connecting plate (613) to align the central axis of the operation board with the through hole. Manually rotate the rotating rod (912), drive the threaded rod (914) to rotate through the meshing of the first bevel gear (913) and the second bevel gear (915). Since the thread directions at both ends of the threaded rod are opposite, the two cleaning plates (918) slide towards each other along the through groove (917) and insert into the through hole to scrape off the blockage; after the cleaning is completed, rotate in the reverse direction and the cleaning plates slide back out in the opposite direction.

[0147] Step 9: Completion of grinding and collection of finished products

[0148] Turn off the drive motor (311). After the collection box (831) completely stops rotating, open the opening cover (835) on the cover (832), and directly take out the ground finished product from the top of the collection box, avoiding disassembling the entire cover and improving the operation convenience.

[0149] It should be noted that the control method of this application can be automatically controlled through a controller. The control method of the controller can be realized by simple programming of those skilled in the art, which belongs to the common general knowledge in the art. And this application mainly aims to protect the mechanical structure, so the control method and circuit connection of this application will not be explained in detail.

The first and second grinding devices are provided, and the two-stage grinding improves the efficiency and quality, makes the particle size of the material uniform, the driving device uses multi-stage gear transmission, the power is stable, the hole cleaning device facilitates the cleaning of the discharge through hole, reduces downtime, and when the collection box rotates, the material collides and rubs under the action of centrifugal force to achieve secondary fine grinding.
