Abstract
Description
Technical Field
[0001] This invention relates to the field of grain grinding technology, specifically to a double-sided open-type multi-stage grain grinding device and grinding method to prevent grain sticking. Background Technology
[0002] Grain milling is a primary processing method for agricultural products. It involves grinding grains (such as wheat, rice, and corn) into powder or other forms to facilitate further processing or direct consumption. Milled grains are commonly used in the food and other industries.
[0003] Current grain grinding equipment is mainly multi-stage grinding equipment. Taking the patent with publication number CN 118454805 B, entitled "A Multi-stage Grinding Equipment for Grain Processing", as an example, this type of multi-stage grinding equipment mostly suffers from the following problems:
[0004] I. Multi-stage grinding equipment usually has multiple grinding mechanisms installed inside. The main components of the grinding mechanism are grinding rollers or grinding discs. As wear parts, these grinding rollers or grinding discs need to be disassembled during regular maintenance to check for wear. However, disassembly requires disassembling each grinding mechanism separately, making disassembly difficult and cumbersome.
[0005] Second, when grains are fed or fed before grinding, they mainly fall vertically onto the grinding rollers or grinding discs, which can easily cause the grains to accumulate together, resulting in uneven or insufficient grinding.
[0006] Third, when grains are being ground, they tend to stick to the inner wall of the grinding roller or grinding disc, which can cause the grinding process to be unsmooth. Summary of the Invention
[0007] The technical problem to be solved by this invention is to provide a double-sided open-type multi-stage grain grinding device and grinding method to prevent grain sticking. The outer grinding part of the grinding device can be flipped open from the left and right sides, allowing direct inspection or replacement of all grinding discs, making regular maintenance more convenient. When the grain is fed, it falls onto the rotating inner grinding part. At this time, under the action of centrifugal force, the grain will slide evenly into the grinding gap, avoiding material accumulation in one place, and making subsequent grinding more uniform and thorough. When the inner grinding part is in operation, it will prevent the grain from sticking to the inner wall by synchronous vibration, making the entire processing process smoother.
[0008] The technical solution of this invention is implemented as follows:
[0009] A double-sided open-type multi-stage grain grinding equipment for preventing grain sticking includes a vertical frame; the top and bottom of the vertical frame are respectively equipped with an inlet section and an outlet section;
[0010] An external grinding part is installed in the middle of the upright part, which connects to the feeding part and the discharging part. This external grinding part can achieve multi-stage fine grinding and can be flipped open from the left and right sides.
[0011] The outer grinding section has a rotating inner grinding section installed inside. This inner grinding section can keep running continuously throughout the grinding process and prevents the grain from sticking to the inner wall by vibrating synchronously during operation.
[0012] Using the above solution, the outer grinding section of the grinding equipment can be flipped open from both sides, allowing for direct inspection or replacement of all grinding discs, making regular maintenance more convenient. When grains are fed, they fall onto the rotating inner grinding section, where they slide evenly into the grinding gaps under the centrifugal force of rotation, preventing material from accumulating in one place and ensuring more even and thorough grinding in subsequent processes. The inner grinding section vibrates synchronously during operation to prevent grains from sticking to the inner wall, making the entire processing process smoother.
[0013] In a preferred embodiment of a double-sided open-type multi-stage grain grinding device for preventing grain sticking, the frame includes a top seat and a base parallel to the top seat, with multiple vertical pillars supporting and connecting the top seat, the base, and the bottom of the base.
[0014] By adopting the above scheme, in order to achieve the integration of the entire grinding equipment, the upright part serves as the overall frame, and the feeding part, discharging part, external grinding part, and internal grinding part are installed together, making the integration of the entire grinding equipment higher.
[0015] As a preferred embodiment of a double-sided open-type multi-stage grain grinding device for preventing grain sticking, the feeding section includes a storage box fixed to the upper surface of the top seat and a feeding box fixed to the lower surface of the top seat, and a material channel located below the top seat is connected between the storage box and the feeding box.
[0016] The bottom surfaces of both the storage bin and the feed channel are sloped, gradually decreasing in slope from the storage bin to the feed box.
[0017] Using the above method, in order to feed the grain, the grain is poured into the storage box, and then the grain slides down the feed channel into the feed box, thus completing the feeding of the grain.
[0018] As a preferred embodiment of a double-sided open-type multi-stage grain grinding device for preventing grain sticking, the discharge section includes a discharge box one fixed to the upper surface of the base and a discharge box two fixed to the lower surface of the base, with the discharge box one and the discharge box two connected vertically.
[0019] The lower opening of discharge box two is flared.
[0020] Using the above scheme, in order to discharge the grain, the fine powder that has been ground will eventually fall from the discharge box two. The lower opening of the discharge box two is made into an flared opening, which can effectively prevent the fine powder from flying away when it falls.
[0021] In a preferred embodiment of a double-sided open-type multi-stage grain grinding equipment for preventing grain sticking, the outer grinding part includes two sets of equally divided multi-stage grinding half-shells. The two sets of multi-stage grinding half-shells are respectively connected to the feed box and the discharge box. The bottom of the two sets of multi-stage grinding half-shells extends into the discharge box and is rotatably installed inside the discharge box. The top of the two sets of multi-stage grinding half-shells is concentrically connected to the outside of the feed box.
[0022] The interior of the two sets of multi-stage grinding half-shells has multiple grinding chambers arranged in a linear array, and the grinding chambers are spherical in shape. The two sets of multi-stage grinding half-shells can be combined to form a complete and sealed multi-stage grinding shell, and the combined multi-stage grinding shell has a shape like a "candied hawthorn".
[0023] Each grinding chamber has a detachable half-surface grinding disc installed in the lower half of the space, and the two sets of half-surface grinding discs can be combined to form a complete outer grinding disc; the inner surface of the outer grinding disc is the grinding surface.
[0024] By adopting the above solution, in order to facilitate the opening of the outer grinding part, the two sets of multi-stage grinding half-shells are flipped down from the middle to both sides, so that all the outer grinding discs and inner grinding discs can be inspected or replaced at the same time, which makes regular maintenance more convenient.
[0025] As a preferred embodiment of a double-sided open-type multi-stage grain anti-sticking grinding device, a side-flip handle is fixed on the top of the multi-stage grinding half-shell, and a quick self-locking component that works in conjunction with the side-flip handle is installed at the bottom of the feed box.
[0026] The quick self-locking assembly includes an N-shaped base fixed to the bottom of the feed box, a slidable latch is installed in the N-shaped base, a push rod is connected above the latch, and a spring is fitted on the latch body.
[0027] The side-flip handle has a lock hole for use with a bolt lock; the bolt lock can be pushed into the lock hole by the elastic push of spring one.
[0028] With the above solution, in order to facilitate opening / closing the external grinding part, when opening, simply pull up the push rod to release the lock in the lock hole, and it can be opened / closed without the need for tools, which makes it more convenient to operate.
[0029] In a preferred embodiment of a double-sided open-type multi-stage grain grinding device for preventing grain sticking, the inner grinding section includes a transmission rod assembly located inside the multi-stage grinding half-shell. This transmission rod assembly is driven to rotate by a motor fixed to the upper surface of the top seat, and an inner grinding disc located inside the grinding chamber is fixed on the transmission rod assembly.
[0030] The sides of the inner grinding disc are grinding surfaces; the top surface of the inner grinding disc is a smooth convex surface.
[0031] Using the above scheme, in order to ensure that the grains are ground evenly and thoroughly after being fed, when the grains fall into the grinding chamber, the inner grinding disc is driven to rotate at this time, and the top surface of the inner grinding disc is a smooth convex surface. After the grains fall onto the top surface of the inner grinding disc, under the action of its rotational centrifugal force, the grains will slide evenly to the surrounding area. Then the grains slide into the gap between the inner grinding disc and the outer grinding disc, and the grains are ground evenly.
[0032] In a preferred embodiment of a double-sided open-type multi-stage grain grinding equipment for preventing grain sticking, a synchronous vibration component is installed in each grinding chamber of the transmission rod assembly;
[0033] The synchronous vibration assembly includes a contact rod and a guide rod. The contact rod and the guide rod are parallel to each other and synchronously slidably mounted on the transmission rod assembly. Two springs are respectively fitted on the contact rod and the guide rod.
[0034] A half-face vibrating disk that works with the contact rod is fixed in the upper half of the grinding chamber. The half-face vibrating disk has multiple circumferentially arrayed vibration grooves.
[0035] The two sets of half-face vibratory discs can be combined to form a complete vibratory disc; the contact rod is longer than the guide rod, and the contact rod can always be in contact with the vibratory disc under the push of the second spring.
[0036] To prevent grains from sticking together during grinding, the contact rod located inside the grinding chamber rotates with the transmission rod assembly during the grinding process. At this time, the contact rod will continuously abut and impact the vibrating plate under the action of spring two, and its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate, which can prevent the grains from sticking to the inner wall.
[0037] In a preferred embodiment of a double-sided open-type multi-stage grain grinding device for preventing grain sticking, the outer grinding disc and the inner grinding disc work together to grind the grain; the distance between all the outer grinding discs and the inner grinding discs gradually decreases from top to bottom.
[0038] Using the above method, in order to achieve fine grinding of grains, an outer grinding disc and an inner grinding disc with different grinding spacing are used for grinding, and the grains will eventually be discharged as fine powder.
[0039] A double-sided open-type multi-stage grinding method for preventing grain sticking is disclosed. This method is implemented using the double-sided open-type multi-stage grinding equipment for preventing grain sticking, and the specific grinding method is as follows:
[0040] S1. Start the motor and pour the grain to be ground into the storage bin. The grain slides down the feed channel into the feed bin, and then falls into the uppermost grinding chamber.
[0041] S2. When the grains fall into the grinding chamber, the inner grinding disc is driven to rotate at this time, and the top surface of the inner grinding disc is a smooth convex surface. After the grains fall to the top surface of the inner grinding disc, under the action of its rotational centrifugal force, the grains will slide evenly to the surrounding area. Then the grains slide into the gap between the inner grinding disc and the outer grinding disc, and the grains are ground evenly.
[0042] S3. Since the distance between all the outer grinding discs and the inner grinding discs gradually decreases from top to bottom, after the grains are ground in multiple stages, they are finally ground into fine powder and discharged from the discharge box at two points, thus completing the grinding of the grains.
[0043] S4. By precisely controlling the amount of grain to be ground poured into the storage bin per unit time, the grain is ground while being poured, eliminating the need to stop the machine for intermittent grinding, thus increasing processing efficiency.
[0044] S5. During the grain grinding process, the contact rod located in the grinding chamber will rotate with the transmission rod assembly. At this time, the contact rod will continuously resist and strike the vibrating plate under the action of spring two. Its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate, which can prevent the grain from sticking to the inner wall.
[0045] S6. With long-term use of the outer and inner grinding discs, they will inevitably need to be replaced due to wear. At this time, pulling up the push rod will release the lock in the lock hole, and the two sets of multi-stage grinding half-shells can be opened from the middle to both sides. All the outer and inner grinding discs can be inspected or replaced at the same time, which is more convenient for regular maintenance.
[0046] After adopting the above technical solution, the beneficial effects of the present invention are:
[0047] 1. The outer grinding section of this grinding equipment can be flipped open from both sides, allowing for direct inspection or replacement of all grinding discs, making regular maintenance more convenient. When grains are fed, they fall onto the rotating inner grinding section. Under the centrifugal force of rotation, the grains slide evenly into the grinding gaps, preventing material from accumulating in one place, resulting in more even and thorough grinding in subsequent processes. The inner grinding section vibrates synchronously during operation to prevent grains from sticking to the inner wall, making the entire processing process smoother.
[0048] 2. To facilitate the opening of the external grinding section, the two sets of multi-stage grinding half-shells can be opened from the middle to both sides, allowing for simultaneous inspection or replacement of all external and internal grinding discs, making regular maintenance more convenient.
[0049] 3. To facilitate opening / closing the external grinding part, simply pull up the push rod to release the lock in the keyhole when opening. No tools are needed to open / close, making it more convenient to operate.
[0050] 4. In order to ensure that the grains are ground evenly and thoroughly after being fed, when the grains fall into the grinding chamber, the inner grinding disc is driven to rotate. Since the top surface of the inner grinding disc is a smooth convex surface, the grains will slide evenly to the surrounding area under the action of centrifugal force after falling onto the top surface of the inner grinding disc. Then the grains slide into the gap between the inner grinding disc and the outer grinding disc, and the grains are ground evenly.
[0051] 5. To prevent grains from sticking together during grinding, the contact rod located in the grinding chamber will rotate with the transmission rod assembly during the grinding process. At this time, the contact rod will continuously abut and strike the vibrating plate under the action of spring two. Its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate, which can prevent the grains from sticking to the inner wall.
[0052] 6. In order to achieve fine grinding of grains, an outer grinding disc and an inner grinding disc with different grinding spacing are used for grinding. The grains will eventually be discharged as fine powder. Attached Figure Description

Detailed Implementation
[0070] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0071] like Figures 1 to 2 As shown, a double-sided open-type multi-stage grain grinding equipment for preventing grain sticking includes a vertical frame 1; the top and bottom of the vertical frame 1 are respectively equipped with a feeding section 2 and a discharging section 3;
[0072] An external grinding part 4 is installed in the middle of the upright part 1, which is connected between the feed part 2 and the discharge part 3. The external grinding part 4 can achieve multi-stage fine grinding and can be flipped open from the left and right sides.
[0073] The outer grinding part 4 is equipped with a rotating inner grinding part 5, which can keep running continuously throughout the grinding process and prevents the grain from sticking to the inner wall by vibrating synchronously during operation.
[0074] The outer grinding section 4 of the grinding equipment can be flipped open from the left and right sides, allowing for direct inspection or replacement of all grinding discs, making regular maintenance more convenient. When grains are fed, they fall onto the rotating inner grinding section 5. Under the action of centrifugal force, the grains slide evenly into the grinding gap, preventing material from accumulating in one place, resulting in more even and thorough grinding in subsequent processes. The inner grinding section 5 vibrates synchronously during operation to prevent grains from sticking to the inner wall, making the entire processing process smoother.
[0075] like Figures 3 to 4 As shown, the frame section 1 includes a top seat 101 and a base 102 parallel to the top seat 101. Multiple vertical support columns 103 are welded between the top seat 101 and the base 102, as well as at the bottom of the base 102. To achieve the integration of the entire grinding equipment, the frame section 1 serves as an integral frame, simultaneously housing the feeding section 2, the discharging section 3, the external grinding section 4, and the internal grinding section 5, resulting in a higher degree of integration of the entire grinding equipment.
[0076] like Figures 3 to 4As shown, the feeding section 2 includes a storage box 201 welded to the upper surface of the top seat 101 and a feeding box 202 welded to the lower surface of the top seat 101. A material channel 203 located below the top seat 101 connects the storage box 201 and the feeding box 202. The bottom surfaces of both the storage box 201 and the material channel 203 are sloped, gradually decreasing in slope from the storage box 201 towards the feeding box 202. To feed the grain, the grain is poured into the storage box 201, and then slides down through the material channel 203 into the feeding box 202, thus completing the grain feeding process.
[0077] like Figures 3 to 4 As shown, the discharge section 3 includes a discharge box 301 fixed to the upper surface of the base 102 and a discharge box 302 fixed to the lower surface of the base 102. The discharge box 301 and the discharge box 302 are vertically connected. The lower opening of the discharge box 302 is flared. In order to discharge the grain, the ground powder finally falls from the discharge box 302. The flared lower opening of the discharge box 302 can effectively prevent the powder from flying when it falls.
[0078] like Figures 5 to 8 As shown, the outer grinding part 4 includes two sets of equally divided multi-stage grinding half-shells 401. The two sets of multi-stage grinding half-shells 401 are respectively connected to the feed box 202 and the discharge box 301. The bottom of the two sets of multi-stage grinding half-shells 401 extends into the discharge box 301 and is rotatably installed in the discharge box 301. The top of the two sets of multi-stage grinding half-shells 401 are respectively concentrically connected to the outside of the feed box 202.
[0079] The interior of the two sets of multi-stage grinding half-shell shells 401 has multiple grinding cavities 402 arranged in a linear array. The grinding cavities 402 are spherical in shape. The two sets of multi-stage grinding half-shell shells 401 can form a complete and sealed multi-stage grinding shell after being combined. A sealing strip is bonded at the joint between the two sets of multi-stage grinding shells, and the combined multi-stage grinding shell has a shape like a "candied hawthorn".
[0080] Each grinding chamber 402 has a half-surface outer grinding disc 403 detachably installed in the lower half of the space, and the two sets of half-surface outer grinding discs 403 can form a complete outer grinding disc after being combined; the inner surface of the outer grinding disc is the grinding surface.
[0081] To facilitate the opening of the outer grinding section 4, the two sets of multi-stage grinding half-shells 401 are flipped down from the middle to both sides, allowing for simultaneous inspection or replacement of all outer grinding discs and inner grinding discs 503, making regular maintenance more convenient.
[0082] like Figures 9 to 10As shown, a side-flip handle 404 is welded and fixed to the top of the multi-stage grinding half-shell 401, and a quick self-locking component that works with the side-flip handle 404 is installed at the bottom of the feed box 202.
[0083] The quick self-locking assembly includes an N-shaped seat 405 fixed to the bottom of the feed box 202 with screws, a mortise lock 406 slidably installed in the N-shaped seat 405, a push rod 407 connected above the mortise lock 406, and a spring 408 fitted on the lock body of the mortise lock 406.
[0084] The side-flip handle has a lock hole 409 for use with a bolt lock 406; the bolt lock 406 can be pushed into the lock hole 409 by the elastic push of the spring 408.
[0085] To facilitate opening / closing the outer grinding part 4, when opening, simply pull up the push rod 407 to release the locking of the mortise lock 406 in the lock hole 409. This allows for opening / closing without the need for tools, making it more convenient to operate.
[0086] like Figures 11 to 12 As shown, the internal grinding part 5 includes a transmission rod assembly 501 located inside the multi-stage grinding half-shell 401. The transmission rod assembly 501 is driven to rotate by a motor 502 fixed on the upper surface of the top seat 101. An internal grinding disc 503 located inside the grinding chamber 402 is fixed on the transmission rod assembly 501.
[0087] The side surface of the inner grinding disc 503 is a grinding surface; the top surface of the inner grinding disc 503 is a smooth convex surface.
[0088] In order to ensure that the grains are ground evenly and thoroughly after being fed, when the grains fall into the grinding chamber 402, the inner grinding disc 503 is driven to rotate at this time, and the top surface of the inner grinding disc 503 is a smooth convex surface. After the grains fall onto the top surface of the inner grinding disc 503, under the action of its rotational centrifugal force, the grains will slide evenly to the surrounding area. Then the grains slide into the gap between the inner grinding disc 503 and the outer grinding disc, and the grains are ground evenly.
[0089] like Figures 13 to 15 As shown, the transmission rod assembly 501 has a synchronous vibration component installed in each grinding chamber 402;
[0090] The synchronous vibration assembly includes a contact rod 504 and a guide rod 505. The contact rod 504 and the guide rod 505 are parallel to each other and synchronously slidably mounted on the transmission rod assembly 501. Springs 506 are respectively fitted on the contact rod 504 and the guide rod 505.
[0091] A half-face vibratory disk 507 that works in conjunction with the contact rod 504 is fixed in the upper half of the grinding chamber 402. The half-face vibratory disk 507 has multiple circumferentially arrayed vibration grooves 508.
[0092] The two sets of half-face vibratory plates 507 can be combined to form a complete vibratory plate; the contact rod 504 is longer than the guide rod 505, and the contact rod 504 can always be in contact with the vibratory plate under the push of the second spring 506.
[0093] To prevent grains from sticking together during grinding, the contact rod 504 located in the grinding chamber 402 rotates with the transmission rod assembly 501 during the grinding process. At this time, the contact rod 504 will continuously abut and impact the vibrating plate under the action of the spring 506, and its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate 503, which can prevent the grains from sticking to the inner wall.
[0094] like Figure 13 As shown, the outer grinding disc and the inner grinding disc 503 work together to grind the grain; the distance between all the outer grinding discs and the inner grinding discs 503 gradually decreases from top to bottom. In order to achieve fine grinding of the grain, multiple levels of outer grinding discs and inner grinding discs 503 with different grinding distances are used for grinding, and the grain will eventually be discharged as fine powder.
[0095] like Figures 1 to 15 As shown, a double-sided open-type multi-stage grinding method for preventing grain sticking is implemented using this double-sided open-type multi-stage grinding equipment. The specific grinding method is as follows:
[0096] S1. Start the motor 502 and pour the grain to be ground into the storage bin 201. The grain slides down the feed channel 203 into the feed bin 202, and then the grain falls into the uppermost grinding chamber 402.
[0097] S2. When the grain falls into the grinding chamber 402, the inner grinding disc 503 is driven to rotate at this time, and the top surface of the inner grinding disc 503 is a smooth convex surface. After the grain falls to the top surface of the inner grinding disc 503, under the action of its rotational centrifugal force, the grain will slide evenly to the surrounding area. Then the grain slides into the gap between the inner grinding disc 503 and the outer grinding disc, and the grain is ground evenly.
[0098] S3. Since the distance between all the outer grinding discs and the inner grinding discs 503 gradually decreases from top to bottom, after the grains are ground in multiple stages, they are finally ground into fine powder and discharged from the discharge box 302, thus completing the grinding of the grains.
[0099] S4. By precisely controlling the amount of grain to be ground poured into the storage bin 201 per unit time, the grain is ground while being poured, eliminating the need to stop the machine for intermittent grinding, thus increasing the processing efficiency.
[0100] S5. During the grain grinding process, the contact rod 504 located in the grinding chamber 402 will rotate with the transmission rod group 501. At this time, the contact rod 504 will continuously resist and impact the vibrating plate under the action of the spring 506. Its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate 503, which can prevent the grain from sticking to the inner wall.
[0101] S6. With the long-term use of the outer and inner grinding discs 503, the outer and inner grinding discs 503 will inevitably need to be replaced due to wear. At this time, pulling up the push rod 407 can release the locking of the latch 406 in the lock hole 409, and the two sets of multi-stage grinding half-shells 401 can be opened from the middle to both sides. All the outer and inner grinding discs 503 can be inspected or replaced at the same time, which is more convenient for regular maintenance.
[0102] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

The outer grinding part is equipped with a rotatable inner grinding part, which can keep running continuously throughout the grinding process and prevents the grain from sticking to the inner wall by synchronous vibration during operation. The external grinding part includes two sets of equally divided multi-stage grinding half-shells. The two sets of multi-stage grinding half-shells are respectively connected to the feed box and the discharge box. The bottom of the two sets of multi-stage grinding half-shells extends into the discharge box and is rotatably installed in the discharge box. The top of the two sets of multi-stage grinding half-shells are respectively concentrically connected to the outside of the feed box. The interior of the two sets of multi-stage grinding half-shells has multiple grinding chambers arranged in a linear array, and the grinding chambers are spherical in shape; the two sets of multi-stage grinding half-shells can be combined to form a complete and sealed multi-stage grinding shell, and the combined multi-stage grinding shell has a shape like a "candied hawthorn". Each grinding chamber has a detachable half-surface grinding disc installed in the lower half of the space, and the two sets of half-surface grinding discs can be combined to form a complete outer grinding disc; the inner surface of the outer grinding disc is the grinding surface. The internal grinding section includes a transmission rod assembly located inside the multi-stage grinding half-shell. This transmission rod assembly is driven to rotate by a motor fixed to the upper surface of the top seat. An internal grinding disc located inside the grinding chamber is fixed on the transmission rod assembly. The side surface of the inner grinding disc is a grinding surface; the top surface of the inner grinding disc is a smooth convex surface. The transmission rod assembly is equipped with a synchronous vibration component in each grinding chamber; The synchronous vibration assembly includes a contact rod and a guide rod. The contact rod and the guide rod are parallel to each other and synchronously slidably mounted on the transmission rod assembly. Springs are respectively fitted on the contact rod and the guide rod. A half-face vibrating disk that works with the contact rod is fixed in the upper half of the grinding chamber. The half-face vibrating disk has multiple circumferentially arrayed vibration grooves. The two sets of half-face vibratory disks can be combined to form a complete vibratory disk; the contact rod is longer than the guide rod, and the contact rod can always be in contact with the vibratory disk under the push of the second spring.

3. The double-sided open-type multi-stage grain grinding equipment for preventing grain sticking as described in claim 2, characterized in that: The top of the multi-stage grinding half-shell is fixed with a side-flip handle, and the bottom of the feed box is equipped with a quick-locking component that works in conjunction with the side-flip handle. The quick self-locking assembly includes an N-shaped base fixed to the bottom of the feed box, a slidable latch is installed in the N-shaped base, a push rod is connected above the latch, and a spring is fitted on the latch body. The side-flip handle has a lock hole for use with a bolt lock; the bolt lock can be pushed into the lock hole by the elastic push of spring one.
4. The double-sided open-type multi-stage grain grinding equipment for preventing grain sticking as described in claim 3, characterized in that: The outer and inner grinding discs work together to grind the grains; the distance between all the outer and inner grinding discs gradually decreases from top to bottom.
5. A double-sided open-type multi-stage grinding method for preventing grain sticking, characterized in that: This method is implemented using the double-sided open-type multi-stage grain anti-sticking grinding equipment according to claim 4, and the specific grinding method is as follows: S1. Start the motor and pour the grain to be ground into the storage bin. The grain slides down the feed channel into the feed bin, and then falls into the uppermost grinding chamber. S2. When the grains fall into the grinding chamber, the inner grinding disc is driven to rotate at this time, and the top surface of the inner grinding disc is a smooth convex surface. After the grains fall to the top surface of the inner grinding disc, under the action of its rotational centrifugal force, the grains will slide evenly to the surrounding area. Then the grains slide into the gap between the inner grinding disc and the outer grinding disc, and the grains are ground evenly. S3. Since the distance between all the outer grinding discs and the inner grinding discs gradually decreases from top to bottom, after the grains are ground in multiple stages, they are finally ground into fine powder and discharged from the discharge box at two points, thus completing the grinding of the grains. S4. By precisely controlling the amount of grain to be ground poured into the storage bin per unit time, the grain is ground while being poured, eliminating the need to stop the machine for intermittent grinding, thus increasing processing efficiency. S5. During the grain grinding process, the contact rod located in the grinding chamber will rotate with the transmission rod assembly. At this time, the contact rod will continuously resist and strike the vibrating plate under the action of spring two. Its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate, which can prevent the grain from sticking to the inner wall. S6. With long-term use of the outer and inner grinding discs, they will inevitably need to be replaced due to wear. At this time, pulling up the push rod will release the lock in the lock hole, and the two sets of multi-stage grinding half-shells can be opened from the middle to both sides. All the outer and inner grinding discs can be inspected or replaced at the same time, which is more convenient for regular maintenance.
