Description

Technical Field

[0001] The invention relates to the technical field of grain grinding, in particular to double-side open grain anti-adhesion multi-stage grinding equipment and a grinding method. Background Art

[0002] Grain grinding is a type of primary processing of agricultural products. It is the process of grinding grains (such as wheat, rice, corn, etc.) into powder or other forms for further processing or direct consumption. Among them, grain grinding is usually used in food and other fields.

[0003] At present, grain grinding equipment is mainly multi-stage grinding equipment. Taking the patent with publication number CN 118454805 B and titled "A multi-stage grinding equipment for grain processing" as an example, most of these multi-stage grinding equipment have the following problems:

[0004] 1. There are usually multiple grinding mechanisms installed inside the multi-stage grinding equipment, and the main components of the grinding mechanism are grinding rollers or grinding discs. The grinding rollers or grinding discs are wear parts, and they need to be disassembled to check the wear during regular maintenance. However, each grinding mechanism needs to be disassembled separately during disassembly, which makes it difficult and cumbersome to disassemble;

[0005] 2. When feeding or feeding grains before grinding, the grains mainly fall vertically onto the grinding roller or grinding disc, which easily causes the grains to accumulate together, resulting in uneven or insufficient grinding;

[0006] 3. When grinding grains, they tend to stick to the inner wall of the grinding roller or grinding disc, causing the grinding process to be not smooth. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a double-sided open grain anti-adhesion multi-stage grinding equipment and a grinding method. The outer grinding part of the grinding equipment can be flipped down and opened from the left and right sides. After opening, all grinding discs can be directly checked or replaced, which is more convenient during regular maintenance; when the grain is unloaded, it will fall onto the rotating inner grinding part. At this time, the grain will evenly slide into the grinding gap under the action of the rotating centrifugal force, avoiding the accumulation of materials in one place, and the subsequent grinding will be more uniform and sufficient; when the inner grinding part is in operation, it will prevent the grain from sticking to the inner wall in a synchronous vibration manner, making the entire processing process smoother.

[0008] The technical solution of the present invention is achieved in this way:

[0009] A double-side open grain anti-adhesion multi-stage grinding device comprises a stand part; a feeding part and a discharging part are respectively installed on the top and bottom of the stand part;

[0010] An outer grinding part is installed in the middle of the stand part, which is connected between the feeding part and the discharging part. The outer grinding part can realize multi-stage fine grinding and can be flipped down and opened from the left and right sides.

[0011] A rotatable inner grinding part is installed inside the outer grinding part. The inner grinding part can keep running without stopping during the whole grinding process and prevent the grains from sticking to the inner wall in a synchronous vibration mode during operation.

[0012] By adopting the above scheme, the outer grinding part of the grinding equipment can be flipped down from the left and right sides to open. After opening, all grinding discs can be directly checked or replaced, which is more convenient for regular maintenance; when the grain is unloaded, it will fall onto the rotating inner grinding part. At this time, the grain will slide evenly into the grinding gap under the action of the rotating centrifugal force, avoiding the accumulation of materials in one place, and the subsequent grinding will be more uniform and sufficient; when the inner grinding part is running, it will prevent the grain from sticking to the inner wall by synchronous vibration, making the whole processing process smoother.

[0013] As a preferred embodiment of a double-sided open grain anti-sticking multi-stage grinding device, the frame part includes a top seat and a base parallel to the top seat, and multiple vertical pillars are supported and connected between the top seat and the base and at the bottom of the base.

[0014] By adopting the above scheme, in order to realize the integration of the whole grinding equipment, the stand part is used as the overall frame, and the feeding part, the discharging part, the external grinding part and the internal grinding part are installed together, so that the whole grinding equipment is more integrated.

[0015] As a preferred embodiment of a double-side open grain anti-adhesion multi-stage grinding device, the feeding part 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 the storage box is connected to the feeding box with a material channel located below the top seat;

[0016] The bottom surface of the material storage box and the bottom surface of the material channel are both inclined surfaces, and the inclined surfaces gradually slope down from where the material storage box is located to where the material feeding box is located.

[0017] In order to realize the feeding of grains by adopting the above scheme, the grains are poured into the storage box, and then the grains slide into the feeding box through the material channel, and then the feeding of grains can be completed.

[0018] As a preferred embodiment of a double-side open grain anti-adhesion multi-stage grinding device, the discharge part includes a discharge box 1 fixed to the upper surface of the base and a discharge box 2 fixed to the lower surface of the base, and the discharge box 1 and the discharge box 2 are connected up and down;

[0019] The lower opening of the second discharge box is expanded.

[0020] By adopting the above scheme, in order to realize the discharge of grains, the ground fine powder finally falls from the second discharge box, wherein the lower opening of the second discharge box is opened into an expanded opening, which can effectively prevent the fine powder from flying when falling.

[0021] As a preferred embodiment of a double-side open grain anti-adhesion multi-stage grinding device, the outer grinding part includes two sets of equally divided multi-stage grinding half-surface shells, and the two sets of multi-stage grinding half-surface shells are respectively connected to the upper and lower sides of the feed box and the discharge box; the bottoms of the two sets of multi-stage grinding half-surface shells are respectively extended into the discharge box and rotatably installed in the discharge box, and the tops of the two sets of multi-stage grinding half-surface shells are respectively concentrically connected to the outside of the feed box;

[0022] The two sets of multi-stage grinding half-surface shells have multiple grinding chambers distributed in a linear array inside, and the grinding chambers are spherical in shape; the two sets of multi-stage grinding half-surface shells can form a complete and closed multi-stage grinding shell after being combined, and the appearance of the combined multi-stage grinding shell is "candied haws" shaped;

[0023] A half-surface outer grinding disc is detachably installed in the lower half space of each grinding chamber, and two groups of half-surface outer grinding discs can form a complete outer grinding disc after being combined; the inner side surface of the outer grinding disc is the grinding surface.

[0024] By adopting the above scheme, in order to facilitate the opening of the outer grinding part, the two sets of multi-stage grinding half-surface shells are flipped down from the middle to both sides to open, so that all the outer grinding discs and inner grinding discs can be checked or replaced at the same time, which is more convenient during regular maintenance.

[0025] As a preferred embodiment of a double-side open grain anti-adhesion multi-stage grinding device, a side-turning handle is fixed on the top of the multi-stage grinding half-surface shell, and a quick self-locking component used in conjunction with the side-turning handle is installed at the bottom of the feed box;

[0026] The quick self-locking assembly comprises an N-shaped seat fixed to the bottom of the feed box, a latch is slidably installed in the N-shaped seat, a push rod is connected to the top of the latch, and a spring is installed on the lock body of the latch;

[0027] The flip handle is provided with a lock hole for use with a latch; the latch can be pushed into the lock hole under the elastic push of a spring.

[0028] By adopting the above scheme, in order to facilitate opening / closing the outer grinding part, when opening, it is only necessary to pull up the push rod to release the lock in the lock hole, and it can be opened / closed without the help of tools, which is more convenient in operation.

[0029] As a preferred embodiment of a double-side open grain anti-adhesion multi-stage grinding device, the inner grinding part includes a transmission rod group located inside the multi-stage grinding half-surface shell, the transmission rod group is driven to rotate by a motor fixed to the upper surface of the top seat, and the transmission rod group is fixed with an inner grinding disc located in the grinding chamber;

[0030] 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.

[0031] By adopting the above scheme, in order to ensure that the grains after being fed can be ground evenly and fully, when the grains fall into the grinding chamber, the inner grinding disk is driven to rotate at this time, and the top surface of the inner grinding disk is a smooth convex surface. After the grains fall to the top surface of the inner grinding disk, under the action of the centrifugal force of its rotation, the grains will slide evenly to the surroundings, and then the grains will slide into the gap between the inner grinding disk and the outer grinding disk, and the grains will be ground evenly.

[0032] As a preferred embodiment of a double-side open grain anti-adhesion multi-stage grinding device, a synchronous vibration component is installed in each grinding chamber of the transmission rod group;

[0033] The synchronous vibration assembly includes a touch rod and a guide rod, the touch rod and the guide rod are parallel to each other and synchronously slidably installed on the transmission rod group, and the touch rod and the guide rod are respectively sleeved with springs;

[0034] A half-surface vibration plate used in conjunction with the feeler rod is fixed in the upper half space of the grinding chamber, and a plurality of vibration grooves distributed in a circumferential array are provided on the half-surface vibration plate;

[0035] The two groups of half-surface vibration disks can form a complete vibration disk after being combined; the touch rod is longer than the guide rod, and the touch rod can always contact the vibration disk under the push of the second spring.

[0036] By adopting the above scheme, in order to prevent the grains from sticking during grinding, during the grain grinding process, the feeler rod located in the grinding chamber will rotate along with the transmission rod group. At this time, the feeler rod will continuously resist and hit the vibration plate under the action of spring 2, and its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate, thereby preventing the grains from sticking to the inner wall.

[0037] As a preferred implementation of a double-sided open grain anti-adhesion multi-stage grinding device, the outer grinding disc and the inner grinding disc work together to grind the grain; the distances between all the outer grinding discs and the inner grinding discs gradually decrease from top to bottom.

[0038] By adopting the above scheme, in order to achieve fine grinding of the grains, the outer grinding disc and the inner grinding disc with multiple levels of different grinding intervals are used for grinding, and the grains will eventually be discharged as fine powder.

[0039] A double-side open type grain anti-adhesion multi-stage grinding method, the method is implemented by using the double-side open type grain anti-adhesion multi-stage grinding equipment, and the specific grinding method is as follows:

[0040] S1, start the motor and pour the grains to be ground into the storage box. The grains slide along the material channel into the feed box, and then the grains fall 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 the centrifugal force of its rotation, the grains will slide evenly to the surroundings, and then the grains will slide into the gap between the inner grinding disc and the outer grinding disc, and the grains will be evenly ground;

[0042] S3. Since the distances between all the outer grinding discs and the inner grinding discs gradually decrease from top to bottom, the grains are finally formed into fine powder after multiple stages of grinding and discharged from the second discharge box, thus completing the grinding of the grains;

[0043] S4. By accurately controlling the amount of grains to be ground into the storage box per unit time, the grains are "ground while being poured". There is no need to stop the machine for grinding, and the processing efficiency is higher.

[0044] S5. During the grain grinding process, the feeler rod in the grinding chamber will rotate with the transmission rod group. At this time, the feeler rod will continuously resist and hit the vibration plate under the action of the second spring, and 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 the long-term use of the outer grinding disc and the inner grinding disc, they will inevitably need to be replaced due to wear. At this time, pull up the push rod to release the lock in the lock hole, and flip down the two sets of multi-stage grinding half-surface shells from the middle to both sides to open them. All the outer grinding discs and the inner grinding discs can be checked 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 part of the grinding equipment can be flipped down from the left and right sides to open. After opening, all grinding discs can be directly checked or replaced, which is more convenient for regular maintenance. When the grain is unloaded, it will fall onto the rotating inner grinding part. At this time, the grain will slide evenly into the grinding gap under the action of the rotating centrifugal force, avoiding the accumulation of materials in one place, and the subsequent grinding will be more uniform and sufficient. When the inner grinding part is running, it will prevent the grain from sticking to the inner wall in a synchronous vibration way, making the whole processing process smoother.

[0048] 2. To facilitate the opening of the outer grinding part, flip down the two sets of multi-stage grinding half-surface shells from the middle to both sides to open them, so that all the outer and inner grinding discs can be checked or replaced at the same time, which is more convenient for regular maintenance;

[0049] 3. In order to facilitate the opening / closing of the outer grinding part, when opening, you only need to pull up the push rod to release the lock in the lock hole. It can be opened / closed without the help of tools, which is more convenient to operate;

[0050] 4. In order to make the grains evenly and fully ground 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 to the top surface of the inner grinding disc, under the action of the centrifugal force of its rotation, the grains will slide evenly to the surroundings, and then the grains will slide into the gap between the inner grinding disc and the outer grinding disc, and the grains will be evenly ground;

[0051] 5. In order to prevent grains from sticking during grinding, during the grain grinding process, the feeler rod in the grinding chamber will rotate with the transmission rod group. At this time, the feeler rod will continuously resist and hit the vibration plate under the action of spring 2, and its vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate, which can prevent grains from sticking to the inner wall;

[0052] 6. In order to achieve fine grinding of grains, outer grinding discs and inner grinding discs with multiple levels of different grinding distances are used for grinding, and the grains will eventually be discharged as fine powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] The outer grinding part 4 of the grinding equipment can be flipped down and opened from the left and right sides. After opening, all grinding discs can be directly checked or replaced, which is more convenient for regular maintenance; when the grains are unloaded, they will fall onto the rotating inner grinding part 5. At this time, the grains will slide evenly into the grinding gap under the action of the rotating centrifugal force, avoiding the accumulation of materials in one place, and the subsequent grinding will be more uniform and sufficient; when the inner grinding part 5 is in operation, it will prevent the grains from sticking to the inner wall in a synchronous vibration manner, making the entire processing process smoother.

[0075] like Figure 3 to Figure 4 As shown, the stand 1 includes a top seat 101 and a base 102 parallel to the top seat 101, and multiple vertical pillars 103 are supported and welded between the top seat 101 and the base 102 and at the bottom of the base 102. In order to realize the integration of the entire grinding equipment, the stand 1 is used as an overall frame, and the feed part 2, the discharge part 3, the outer grinding part 4 and the inner grinding part 5 are installed together, so that the integration of the entire grinding equipment is higher.

[0076] like Figure 3 to Figure 4As shown, the feeding part 2 includes a storage box welded and fixed to the upper surface of the top seat 101 and a feeding box 202 welded and fixed to the lower surface of the top seat 101, and the storage box and the feeding box 202 are connected to each other with a material channel 203 located below the top seat 101; the bottom surface of the storage box and the bottom surface of the material channel 203 are both inclined surfaces, and the inclined surface gradually decreases from the storage box to the feeding box 202. In order to realize the feeding of grains, the grains are poured into the storage box, and then the grains slide into the feeding box 202 through the material channel 203, and then the feeding of grains can be completed.

[0077] like Figure 3 to Figure 4 As shown, the discharging part 3 includes a discharging box 1 301 fixed to the upper surface of the base 102 and a discharging box 2 302 fixed to the lower surface of the base 102, and the discharging box 1 301 and the discharging box 2 302 are connected up and down; the lower opening of the discharging box 2 302 is expanded. In order to realize the discharging of the grains, the ground fine powder finally falls from the discharging box 2 302, wherein the lower opening of the discharging box 2 302 is expanded, which can effectively prevent the fine powder from flying when falling.

[0078] like Figures 5 to 8 As shown, the outer grinding part 4 includes two sets of equally divided multi-stage grinding half-surface shells 401, and the two sets of multi-stage grinding half-surface shells 401 are respectively connected with the feed box 202 and the discharge box 301 up and down; the bottoms of the two sets of multi-stage grinding half-surface shells 401 are respectively extended into the discharge box 301 and rotatably installed in the discharge box 301, and the tops of the two sets of multi-stage grinding half-surface shells 401 are respectively concentrically connected to the outside of the feed box 202;

[0079] The two sets of multi-stage grinding half-surface shells 401 have multiple grinding chambers 402 distributed in a linear array inside, and the grinding chambers 402 are spherical in shape; the two sets of multi-stage grinding half-surface shells 401 can form a complete and closed multi-stage grinding shell after being merged, and a sealing strip will be bonded at the joint between the two sets of multi-stage grinding shells, and the appearance of the merged multi-stage grinding shell is "candied haws";

[0080] A half-surface outer grinding disc 403 is detachably installed in the lower half space of each grinding chamber 402, and two groups of half-surface outer grinding discs 403 can form a complete outer grinding disc after being combined; the inner side surface of the outer grinding disc is the grinding surface.

[0081] In order to facilitate the opening of the outer grinding part 4, the two sets of multi-stage grinding half-surface shells 401 are opened from the middle to both sides, so that all the outer grinding discs and the inner grinding discs 503 can be checked or replaced at the same time, which is more convenient during regular maintenance.

[0082] like Figures 9 and 10As shown, a rollover handle 404 is welded and fixed on the top of the multi-stage grinding half-surface shell 401, and a quick self-locking component used in conjunction with the rollover 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 by screws, a latch 406 is slidably installed in the N-shaped seat 405, a push rod 407 is connected to the top of the latch 406, and a spring 408 is mounted on the lock body of the latch 406;

[0084] The flip handle is provided with a lock hole 409 for use with the latch 406 ; the latch 406 can be pushed into the lock hole 409 under the elastic push of a spring 408 .

[0085] In order to facilitate opening / closing of the outer grinding part 4, when opening, it is only necessary to pull up the push rod 407 to release the lock of the latch 406 in the lock hole 409, and it can be opened / closed without the aid of tools, which is more convenient to operate.

[0086] like Figure 11 to Figure 12 As shown, the inner grinding part 5 includes a transmission rod group 501 located inside the multi-stage grinding half-surface housing 401, and the transmission rod group 501 is driven to rotate by a motor 502 fixed to the upper surface of the top seat 101, and an inner grinding disc 503 located in the grinding chamber 402 is fixed on the transmission rod group 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 can be ground evenly and fully after being fed, when the grains fall into the grinding chamber 402, the inner grinding disk 503 is driven to rotate at this time, and the top surface of the inner grinding disk 503 is a smooth convex surface. After the grains fall to the top surface of the inner grinding disk 503, under the action of the centrifugal force of its rotation, the grains will slide evenly to the surroundings, and then the grains will slide into the gap between the inner grinding disk 503 and the outer grinding disk, and the grains will be ground evenly.

[0089] like Figures 13 to 15 As shown, the transmission rod group 501 is respectively equipped with a synchronous vibration component in each grinding chamber 402;

[0090] The synchronous vibration assembly includes a touch rod 504 and a guide rod 505. The touch rod 504 and the guide rod 505 are parallel to each other and synchronously slidably installed on the transmission rod group 501. The touch rod 504 and the guide rod 505 are respectively sleeved with a spring 506.

[0091] A half-surface vibration plate 507 used in conjunction with the feeler rod 504 is fixed in the upper half space of the grinding chamber 402, and a plurality of vibration grooves 508 distributed in a circumferential array are formed on the half-surface vibration plate 507;

[0092] The two groups of half-surface vibration disks 507 can form a complete vibration disk after being combined; the touch rod 504 is longer than the guide rod 505, and the touch rod 504 can always contact the vibration disk under the push of the second spring 506.

[0093] In order to prevent grains from sticking together during grinding, during the grain grinding process, the feeler rod 504 located in the grinding chamber 402 will rotate along with the transmission rod group 501. At this time, the feeler rod 504 will continuously resist and hit the vibration plate under the action of the spring 2 506, and the vibration will be continuously transmitted to the outer grinding plate and the inner grinding plate 503, thereby preventing grains from sticking to the inner wall.

[0094] like Fig.13 As shown, the outer grinding disc and the inner grinding disc 503 work together to grind the grains; the spacing between all the outer grinding discs and the inner grinding disc 503 gradually decreases from top to bottom. In order to achieve fine grinding of the grains, the outer grinding discs and the inner grinding disc 503 with different grinding spacings are used for grinding, and the grains are finally discharged as fine powder.

[0095] like Figures 1 to 15 As shown, a double-side open grain anti-adhesion multi-stage grinding method is implemented using the double-side open grain anti-adhesion multi-stage grinding device, and the specific grinding method is as follows:

[0096] S1, start the motor 502 and pour the grains to be ground into the storage box, the grains slide along the material channel 203 into the feeding box 202, and then the grains fall into the uppermost grinding chamber 402;

[0097] S2, when the grains fall into the grinding chamber 402, since 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 to the top surface of the inner grinding disc 503, under the action of the centrifugal force of its rotation, the grains will slide evenly to the surroundings, and then the grains will slide into the gap between the inner grinding disc 503 and the outer grinding disc, and the grains will be evenly ground;

[0098] S3, since the distances between all the outer grinding discs and the inner grinding disc 503 are gradually reduced from top to bottom, the grains are finally formed into fine powder after multi-stage grinding and discharged from the second discharge box 302, and the grinding of the grains is completed;

[0099] S4. By accurately controlling the amount of grains to be ground into the storage box per unit time, the grains are "ground while being poured". There is no need to stop the machine for grinding, and the processing efficiency is higher.

[0100] S5. During the grain grinding process, the feeler rod 504 in the grinding chamber 402 will rotate along with the transmission rod group 501. At this time, the feeler rod 504 will continuously resist and hit the vibration plate under the action of the second spring 506, and the 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 grinding disc and the inner grinding disc 503, the outer grinding disc and the inner grinding disc 503 will inevitably need to be replaced due to wear. At this time, pulling up the push rod 407 can release the lock of the latch 406 in the lock hole 409, and the two sets of multi-stage grinding half-surface shells 401 are flipped down from the middle to both sides to open, so that all the outer grinding discs and the inner grinding disc 503 can be checked or replaced at the same time, which is more convenient for regular maintenance.

[0102] The above are only 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 in the protection scope of the present invention.

10. A double-side open grain anti-adhesion multi-stage grinding method, characterized in that: The method is implemented using the double-side open grain anti-adhesion multi-stage grinding device according to claim 9, and the specific grinding method is as follows: S1, start the motor and pour the grains to be ground into the storage box. The grains slide along the material channel into the feed box, and then the grains fall 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 the centrifugal force of its rotation, the grains will slide evenly to the surroundings, and then the grains will slide into the gap between the inner grinding disc and the outer grinding disc, and the grains will be evenly ground; S3. Since the distances between all the outer grinding discs and the inner grinding discs gradually decrease from top to bottom, the grains are finally formed into fine powder after multiple stages of grinding and discharged from the second discharge box, thus completing the grinding of the grains; S4. By precisely controlling the amount of grains to be ground into the storage box per unit time, the grains are "ground while being poured". There is no need to stop the machine for grinding, and the processing efficiency is higher. S5. During the grain grinding process, the feeler rod in the grinding chamber will rotate with the transmission rod group. At this time, the feeler rod will continuously resist and hit the vibration plate under the action of the second spring, and 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 the long-term use of the outer grinding disc and the inner grinding disc, they will inevitably need to be replaced due to wear. At this time, pull up the push rod to release the lock in the lock hole, and flip down the two sets of multi-stage grinding half-surface shells from the middle to both sides to open them. All the outer grinding discs and the inner grinding discs can be checked or replaced at the same time, which is more convenient for regular maintenance.
