Description

Technical Field

[0001] The present application relates to the technical field of seafood processing, and specifically discloses a grinding device for seafood processing. Background Art

[0002] Seafood refers to products that can be eaten or used in the ocean. The range is very wide. Most of them refer to marine animals and marine plants. Seaweed: hair algae, laver, kelp, shrimp: lobster, lobster, shrimp. Seafood is a natural health product suitable for human consumption. Even regular and small amounts of fish and other seafood can greatly reduce the risk of death from heart disease. Marine fish, kelp and other seaweed seafood are rich in various trace elements, which help the human body's metabolism and prevent the formation of free radicals. Kelp can also selectively filter out heavy metal carcinogens such as cadmium and strontium;

[0003] Generally speaking, seafood is divided into dried seafood and fresh seafood. Different types are suitable for different groups of people. For dried seafood, dried seafood refers to fresh marine animal and plant raw materials, fungi and algae raw materials that have been dehydrated and dried. They are referred to as dried seafood or dry materials. Dried seafood mainly includes shrimp, shrimp skin, scallops, sea red, dried squid, dried cuttlefish, dried snail meat, dried whitebait, shark fin, dried sea cucumber, dried abalone, fish maw, seaweed, kelp, etc. Fishermen on the coast sometimes catch too much seafood. In order to facilitate storage, they will make it into dried seafood. Some dried seafood needs to be ground into powder by a grinding device during the processing to facilitate human absorption.

[0004] For grinding, a grinding disc is usually used. Only with a grinding disc or other similar devices, the powder produced will be finer and more uniform. However, the common grinding disc grinding device is not suitable for dry seafood. First of all, the volume of dry seafood is too large. Although there is no water after dehydration, it is not very brittle. Therefore, direct grinding disc grinding cannot obtain a finer and more uniform powder. This is also a problem with a grinding device for processing dry seafood with adjustable coarseness and fineness in China's publication number CN217646503U. Therefore, for the grinding of dry seafood, the volume of the dry seafood should be reduced, that is, it should be cut or damaged, so that it is conducive to subsequent grinding. In view of this, the inventor proposes a grinding device for processing seafood. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the traditional grinding equipment for processing seafood has poor grinding fineness and uniformity for some non-brittle seafood after dehydration.

[0006] In order to achieve the above object, the present invention provides the following basic scheme:

[0007] A grinding device for processing seafood, comprising a shredding box, a motor arranged on the shredding box and a plurality of feed pipes, a connecting pipe detachably connected to the shredding box, an extrusion deformation component arranged in the connecting pipe, a lifting grinding box detachably connected to the other end of the connecting pipe, and a plurality of discharge pipes arranged at the bottom of the lifting grinding box;

[0008] A gap circumferential deceleration component is provided in the connecting pipe below the extrusion deformation component, and the gap circumferential deceleration component is used in conjunction with the lifting grinding box;

[0009] A liftable first grinding disc and a rotatable second grinding disc are arranged in the lift grinding box. The first grinding disc and the box wall of the lift grinding box form a grinding surface, and the second grinding disc and the bottom and box wall of the lift grinding box form a grinding surface.

[0010] The principles and effects of this basic solution are:

[0011] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The device integrates the shredding box and the lifting grinding box, which is suitable for grinding non-brittle seafood after dehydration. It is used to reduce the volume of dehydrated seafood, which is beneficial to the subsequent grinding of seafood, thereby improving the fineness and uniformity of seafood grinding.

[0012] 2. Compared with the prior art, this device is designed with a motor based on the shredding box, and a lifting and grinding box is designed based on the motor. Due to the mismatch in rotation speed between the two, the shredding box requires a high rotation speed, while the lifting and grinding box requires a low rotation speed. This device is designed with a gap circumferential reduction assembly, which is used to achieve deceleration, so that the motor can work together on the shredding box and the lifting and grinding box.

[0013] 3. Compared with the prior art, this case designs a gap circumferential deceleration component, which can not only effectively achieve speed reduction, but also realize gap circumferential remote motion. With the support of the gap circumferential remote motion, the lifting and grinding box can complete gap lifting and gap grinding, simulating the pause process. This pause process is very important and can effectively reduce heat generation, thereby ensuring the quality of the seafood after grinding. In addition, because long-term continuous work will reduce the service life, this mode can effectively increase the service life of the device.

[0014] 4. Compared with the prior art, for the first grinding disc, the first grinding disc can not only be lifted and lowered, but also be lifted and lowered intermittently; for the second grinding disc, the second grinding disc can not only be rotated, but also be rotated intermittently; since the first grinding disc and the box wall of the lifting grinding box form a grinding surface, and the first grinding disc is in a lifting state, the contact surface between the grinding surface and the seafood is slowly changing. This design can solve the problem that the contact surface between the grinding surface and the seafood is deteriorated due to the increase of seafood powder.

[0015] 5. Compared with the prior art, the second grinding disc, the bottom and the wall of the lifting grinding box form a grinding surface, and the second grinding disc is in a gap rotation state. The gap rotation not only makes the seafood fall on the bottom of the lifting grinding box, but also because the second grinding disc, the bottom and the wall of the lifting grinding box form a grinding surface, the coverage is wider, and the grinding of all seafood will not deviate from the grinding of the box wall and the bottom of the lifting grinding box, so that the powder output effect is good, and because the second grinding disc is in a gap rotation state, the second grinding disc and the bottom of the lifting grinding box are used to form a traditional graphite structure, and because it is in a gap rotation state, the motion state simulates the gap rotation of graphite, so that the effect of the second grinding disc is better, and the fineness and uniformity of the grinding of seafood are improved.

[0037] A gap circumferential deceleration component is provided in the connecting pipe 4 below the extrusion deformation component, and the gap circumferential deceleration component is used in conjunction with the lifting grinding box 6;

[0038] A liftable first grinding disc 38 and a rotatable second grinding disc 37 are provided in the liftable grinding box 6. The first grinding disc 38 and the box wall of the liftable grinding box 6 form a grinding surface, and the second grinding disc 37 and the bottom and box wall of the liftable grinding box 6 form a grinding surface 35.

[0039] About the shredder box, such as Figure 1 As shown, the device adopts a two-stage shearing box. To be precise, the shearing box includes a first box body 1, a second box body 2 and a connecting ring 3 which are connected in sequence from top to bottom. The motor 9 is installed on the first box body 1. The output shaft of the motor 9 is provided with a connecting shaft 12. The connecting shaft 12 passes through the first box body 1 and exits from the connecting ring 3. The first box body 1 is provided with a first shearing tooth 15, and the second box body 2 is provided with a second shearing tooth 13. The first shearing tooth 15 and the second shearing tooth 13 are both coaxially connected to the connecting shaft 12.

[0040] A first shearing tooth 15 and a second shearing tooth 13 are provided to reduce the volume of dehydrated seafood with a larger volume. The design of the first shearing tooth 15 and the second shearing tooth 13 is conducive to reducing the volume of dehydrated seafood. In terms of specific structure: the size of the first box body 1 is larger than the size of the second box body 2, the size of the first shearing tooth 15 in the first box body 1 is larger than the size of the second shearing tooth 13 in the second box body 2, and the connection between the second box body 2 and the connecting ring 3 is an inclined surface. The design of the inclined surface makes the transition between the first box body 1 and the second box body 2 more beautiful and also facilitates the transition of dehydrated seafood;

[0041] Regarding the connecting pipe 4: both ends of the connecting pipe 4 are provided with external threads, the connecting pipe 4 is threadedly connected to the connecting ring 3, the other end of the connecting pipe 4 is connected to the extension pipe 5, the extension pipe 5 is connected to the lifting grinding box 6, a circular plate 10 is installed in the connecting ring 3, and a rotating bearing 16 is provided at the connection between the circular plate 10 and the connecting shaft 12, and a plurality of leakage holes 1001 are provided on the circular plate 10, and the leakage holes 1001 are all inclined on all sides.

[0042] Specifically: the shredded seafood enters the connecting pipe 4 from the leak hole 1001 and is then squeezed and deformed by the components.

[0043] About the extrusion deformation component: the extrusion deformation component includes a rotating shaft 17 coaxially connected to the connecting shaft 12 on the lower side of the circular plate 10, a first extrusion roller 18, a second extrusion roller 19 and a third extrusion roller 20 arranged in sequence on the rotating shaft 17, and the first extrusion roller 18, the second extrusion roller 19 and the third extrusion roller 20 are each provided with a plurality of extrusion teeth, and the density of the extrusion teeth located on the first extrusion roller 18, the second extrusion roller 19 and the third extrusion roller 20 gradually increases.

[0044] The first squeezing roller 18, the second squeezing roller 19 and the third squeezing roller 20 are used in conjunction with the inner wall of the connecting tube 4 to act on the shredded seafood, causing the seafood to be squeezed and deformed, and the texture of the seafood is disconnected, which is beneficial to subsequent grinding.

[0045] In this process: since the device is based on the shredding box, the motor 9 is designed, and the lifting grinding box 6 is designed based on the motor 9. Due to the mismatch between the rotation speeds of the two, the shredding box requires a high rotation speed, and the lifting grinding box 6 requires a low rotation speed. The device is designed with a gap circumferential reduction component, which is used to achieve deceleration, so that the motor 9 can work together on the shredding box and the lifting grinding box 6. To be precise:

[0046] The clearance circumferential reduction assembly is connected to the rotating shaft 17, and the clearance circumferential reduction assembly includes a reduction box 21, support rods 22 arranged on both sides of the reduction box 21 for supporting the reduction box 21, and a guide plate 39 arranged on the reduction box 21. The design of the guide plate 39 is to prevent the seafood from hitting the reduction box 21 and also facilitate the rapid drop of the seafood, a first gear set 24 coaxially connected to the rotating shaft 17 arranged in the reduction box 21, a second gear set 25 meshing with the first gear set 24, and a connecting rod 39 connected to the second gear set 25. The connecting member and the rotating disk 31 that rotates with clearance based on the movement of the connecting member, the rotating disk 31 is coaxially connected with the clearance rotating shaft 23 at one end away from the rotating shaft 17, the connecting member includes an arc member 29, an intermediate member 27 and a guide member 28, the arc member 29, the intermediate member 27 and the guide member 28 are integrally formed, the arc member 29 slides on the inner wall of the rotating disk 31, the rotating disk 31 is provided with a plurality of guide grooves 30, the guide member 28 can slide in the guide grooves 30, and the rotating shaft 17 is sleeved with a mounting plate 26 for fixing the position of the second gear set 25.

[0047] Specifically: the rotating shaft 17 rotates, causing the first gear set 24 to rotate, the first gear set 24 rotates to cause the second gear set 25 to rotate, the second gear set 25 rotates to cause the connecting member to rotate, and the guide member 28 in the connecting member slides into the guide groove 30 with clearance, and the rotating disk 31 rotates under the action of the guide groove 30, so that the rotating disk 31 can rotate with clearance, and when the rotating disk 31 can rotate with clearance, the clearance rotating shaft 23 connected to the rotating disk 31 performs clearance circular motion. Since the second gear set 25 has no support point, a mounting plate 26 is designed, and the mounting plate 26 is sleeved on the rotating shaft 17. Since the rotating shaft 17 can rotate, a rotating bearing 16 is provided at this connection to avoid the rotation influence of the rotating shaft 17.

[0048] At this time, the rotation speed has dropped, the gap rotating shaft 23 passes through the lifting grinding box 6 and is connected with the first grinding disc 38 and the second grinding disc 37 in the lifting grinding box 6, the gap rotating shaft 23 passes through the lifting grinding box 6 and is coaxially connected with the threaded rod 32, the free end of the threaded rod 32 is rotatably connected to the bottom of the inner box of the lifting grinding box 6, the first grinding disc 38 is screw-connected to the threaded rod 32, and the second grinding disc 37 is threadedly connected to the threaded rod 32.

[0049] Specifically: a first block 36 and a second block 34 are provided at both ends of the threaded rod 32, the second block 34 is embedded with the inner bottom of the lifting grinding box 6, the first block 36 is provided with a stabilizing rod 40 for lifting the first grinding disc 38, and the free end of the stabilizing rod 40 is provided with a limit block, and also includes a pressure touch controller for reversing the motor 9, the pressure touch controller is respectively installed on the first block 36 and the limit block, and the pressure touch controller realizes the reversal of the motor 9, thereby completing the lifting and reciprocating of the first grinding disc 38.

[0050] Due to the rotation of the threaded rod 32, the first grinding disc 38 is lifted and lowered under the action of the stabilizing rod 40. In addition, due to the rotation of the threaded rod 32, the second grinding disc 37 is moved circumferentially.

[0051] In this process, in order to improve the grinding effect, the first grinding disc 38 is surrounded by horizontal grinding patterns 3801, and the second grinding disc 37 is surrounded by vertical grinding patterns 3701. An inclined plate is provided on the upper side of the first grinding disc 38 away from the second grinding disc 37. The horizontal grinding patterns 3801 are used to reversely combine lifting and lowering, and the vertical grinding patterns 3701 are used to combine rotation, so as to achieve a better grinding effect.

[0052] Since the first grinding disc 38 does not rotate, an inclined plate is designed to prevent the seafood from falling on the inclined plate and being unable to be ground.

[0053] Specific implementation process:

[0054] In the first step, the dehydrated seafood enters from the feed pipe 8, and is affected by the shredder box, and its volume begins to decrease. Then it enters the connecting pipe 4 through the leakage hole 1001, and is affected by the extrusion deformation component. Then it continues to move downward and enters the lifting and grinding box 6. The first grinding disc 38 and the box wall of the lifting and grinding box 6 form a rubbing surface. Under the action of the inclined plate, the seafood enters the rubbing surface. Since the first grinding disc 38 will rise and fall, the seafood is subjected to a period of rubbing.

[0055] In the second step, the seafood continues to move downward, and the second grinding disc 37, the bottom of the lifting grinding box 6 and the box wall form a grinding surface 35. Since the second grinding disc 37 rotates, it is first ground by the box wall and the second grinding disc 37, and then falls on the bottom of the lifting grinding box 6 and the bottom of the second grinding disc 37 to be ground again. Moreover, since the second grinding disc 37 rotates, a certain centrifugal force will be generated, so that the seafood will undergo the above-mentioned two grinding effects, thereby improving the grinding uniformity of the seafood.

[0056] The third step, finally, open the discharge pipe 11 and take out the ground seafood. The device is provided with multiple feed pipes 8. The multiple feed pipes 8 are not only suitable for the rapid feeding of the same product, but also for the mixed feeding of different products and the subsequent mixing into powder.

[0057] The device solves the problem that the traditional grinding equipment for seafood processing has poor grinding fineness and uniformity for some non-brittle seafood after dehydration.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
