Technical Field

[0001] The invention relates to the technical field of pulverizing equipment, and in particular to a pulverizing device for frozen fish. Background Art

[0002] After the fish is frozen, it is generally necessary to break the whole piece of fish meat into pieces to facilitate subsequent processing. At present, after the existing crushing equipment completes the crushing of the frozen fish, the crushed fish will be mixed with incompletely crushed fish, which affects the quality of the finished product. It is necessary to screen them out and then perform secondary processing, which wastes manpower and material resources.

[0003] To solve the above problems, a Chinese patent with publication number CN219631442U discloses a grinding device for seafood processing, including a grinding chamber, a crushing chamber fixedly installed on the upper wall of the grinding chamber, a feed port is provided on one side wall of the crushing chamber, a feed hopper is installed at the feed port, a crushing mechanism is installed in the crushing chamber, a connecting hole is provided between the crushing chamber and the grinding chamber, a grinding mechanism is installed in the grinding chamber, a return chamber is installed on one side of the grinding chamber, and a return mechanism is installed in the return chamber; the device screens the powder through a first screening plate, qualified powder leaves through the discharge port, unqualified particles enter the return chamber through the slope structure at the lower end, the conveying roller is driven to rotate by a third motor, and the particles are conveyed back to the grinding chamber for secondary processing, so that the grinding effect is more sufficient, the operation is simple, and it brings convenience to people.

[0004] The above-mentioned device has the following problems during actual use: during screening by the first screen plate, particles are easily blocked in the first screen plate, and the device does not have a cleaning mechanism to clean the particles on the first screen plate, so that more and more particles are blocked on the first screen plate, which in turn causes the first screen plate to be blocked and stop screening particles, thereby affecting the crushing effect and reducing the crushing efficiency; and, if the first screen plate is taken out by a worker after being used for a period of time, but the first screen plate is only cleaned once, some particles will still remain on the first screen plate, which on the one hand affects the reuse of the first screen plate, and on the other hand reduces the filtration efficiency of the first screen plate. However, if the worker cleans the first screen plate many times, it will increase the difficulty of cleaning for the worker, and the workload will be large and the work will be cumbersome. Summary of the invention

[0005] The invention provides a crushing device for frozen fish, so as to solve the problem that the existing grinding device cannot clean the first screening plate.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a crushing device for frozen fish, comprising a cylindrical barrel with an inlet, and also comprising a crushing mechanism arranged in the cylindrical barrel; the crushing mechanism comprises a screening plate, a vibration assembly, a first crushing roller, a second crushing roller, a bottom hole opened on the cylindrical barrel, and a driving assembly for driving the first crushing roller and the second crushing roller to rotate; the screening plate is fixedly connected to the bottom hole; the vibration assembly comprises a vibration part symmetrically arranged on both sides of the cylindrical barrel along the axial direction of the cylindrical barrel; the vibration part comprises an auxiliary plate, a vibration block, and a motion unit for driving the auxiliary plate to perform vertical reciprocating motion; the auxiliary plate is vertically slidably connected to the cylindrical barrel; the vibration block is fixedly connected to the auxiliary plate, and the screening plate is located on the motion trajectory of the vibration block.

[0007] The principles and advantages of this solution are:

[0008] 1. Workers put the frozen fish to be crushed into the cylindrical barrel along the inlet. After the frozen fish are placed, the first crushing roller and the second crushing roller are driven to rotate by the driving assembly. During the rotation of the first crushing roller and the second crushing roller, the frozen fish can be crushed to reduce the particle size of the frozen fish, and screened through the screening plate, so that the frozen fish with qualified particle size falls into the collection box below the cylindrical barrel through the screening plate; the frozen fish with unqualified particle size is retained on the screening plate, so that it is again subjected to the joint action of the first crushing roller and the second crushing roller until the particle size of the frozen fish is qualified; that is, through the joint action of the first crushing roller, the second crushing roller and the screening plate, it can be ensured that all frozen fish are crushed comprehensively and evenly.

[0009] 2. During the crushing of frozen fish, the auxiliary plate is driven by the motion unit to perform vertical reciprocating motion; during the vertical reciprocating motion of the auxiliary plate, the vibration block moves synchronously; during the movement of the vibration block, the vibration block can continuously impact the screening plate, causing the screening plate to vibrate; the vibrating screening plate can cause the frozen fish particles blocked in the screening holes on the screening plate to perform vertical reciprocating motion, and finally fall somewhere on the screening plate, thereby changing the position of the frozen fish particles on the screening plate, thereby ensuring that the frozen fish particles will not be blocked at the screening holes on the screening plate, enhancing the screening effect of the screening plate, and improving the screening capacity of the screening plate, that is, the screening plate can continuously and efficiently screen the frozen fish particles.

[0010] Furthermore, during the vertical reciprocating motion of the vibration block, the vibration block can impact the frozen fish, breaking the hard shell on the surface of the frozen fish, making the frozen fish soft, thereby increasing the crushing effect of the first crushing roller and the second crushing roller on the frozen fish, and improving the crushing effect on the frozen fish.

[0011] Furthermore, it also includes a scraping part; the scraping part includes a circular ring, a plurality of scraping blocks, and a power unit for driving the circular ring to rotate; the circular ring is rotatably connected to the cylindrical tube; the plurality of scraping blocks are equidistantly arranged along the circumferential direction of the circular ring; the scraping blocks are fixedly connected to the circular ring; and the scraping blocks are in contact with the inner wall of the cylindrical tube.

[0012] The circular ring is driven to rotate by the power unit, and the scraper moves synchronously during the rotation of the circular ring. During the movement of the scraper, the scraper can scrape off the frozen fish particles blocked on the screening plate, so that the frozen fish particles no longer block the screening plate, thereby further enhancing the screening effect of the screening plate.

[0013] Furthermore, a wedge groove is provided on the bottom hole, and the upper surface of the screening plate is lower than the upper surface of the bottom hole; it also includes an auxiliary unit arranged on the scraper block; the auxiliary unit includes an auxiliary block, a spherical wedge block, a first spring, and a through hole opened on the scraper block; the auxiliary block is slidably connected to the through hole; the spherical wedge block is fixedly connected to the auxiliary block, and the spherical wedge block is abutted against the inner wall of the cylindrical tube; bristle blocks are respectively provided on both sides of the spherical wedge block, and the bristle block is fixedly connected to the auxiliary block; the spherical wedge block and the bristle block are both located in the through hole, and the spherical wedge block and the bristle block can slide in and out of the through hole; the wedge groove is located on the movement trajectory of the spherical wedge block; the two ends of the first spring are respectively connected to the auxiliary block and the scraper block.

[0014] During the movement of the scraper block, the auxiliary block moves synchronously; during the movement of the auxiliary block, when the auxiliary block moves to the position of the screening plate, the first spring drives the auxiliary block to move close to the position of the screening plate, and the brush block and the spherical wedge block move synchronously; during the movement of the brush block, the brush block has a certain force, and the brush block can also extend into the screening hole of the screening plate, thereby prompting the frozen fish particles blocked in the screening hole to fall, thereby further enhancing the screening effect of the screening plate, and comprehensively ensuring that the screening plate will not be blocked, so that the screening plate is always in an efficient screening state.

[0015] When the spherical wedge moves to the position where the wedge groove is located, the spherical wedge drives the auxiliary block to reset under the action of the wedge groove, so that the first spring is compressed, thereby facilitating the auxiliary block to drive the brush block to move closer to the screening plate again.

[0016] To sum up, through the joint action of the vibration block, the scraper block and the brush block, the screen plate can be comprehensively cleaned, so that the screen plate is cleaned more completely and fully, the screening effect of the screen plate is enhanced, the screening efficiency of the screen plate is improved, and it is ensured that all the frozen fish in the cylindrical barrel can fall along the screen plate, thereby improving the utilization rate of the frozen fish.

[0018] During the crushing of frozen fish, the driving unit drives the linkage block to perform vertical reciprocating motion; during the movement of the linkage block, the throwing block moves synchronously; during the movement of the throwing block, the throwing block can drive the frozen fish particles to fly from bottom to top along the height direction of the cylindrical barrel to both sides of the throwing block, thereby expanding the distribution range of the frozen fish and finally falling into the cylindrical barrel, further ensuring that the frozen fish is more evenly distributed in the cylindrical barrel, thereby enhancing the crushing effect of the first crushing roller and the second crushing roller.

[0019] Furthermore, it also includes a cutting part symmetrically arranged on both sides of the cylindrical barrel along the axial direction of the cylindrical barrel; the cutting part includes a transverse plate, a first rack, a second rack, a short shaft, a first gear, and a plurality of cutting knives; the transverse plate is vertically slidably connected to the cylindrical barrel; the first rack is fixedly connected to the transverse plate; the second rack is fixedly connected to the linkage block; the short shaft is rotationally connected to the cylindrical barrel; the first gear is fixedly connected to the short shaft, and the first gear is respectively engaged with the first rack and the second rack; a plurality of cutting knives are equidistantly arranged along the length direction of the transverse plate, and the cutting knives are fixedly connected to the transverse plate.

[0020] During the vertical reciprocating motion of the linkage block, the second rack moves synchronously; during the movement of the second rack, the second rack is engaged with the first gear, thereby rotating the first gear; during the rotation of the first gear, the first gear is engaged with the first rack, thereby enabling the first rack to perform vertical reciprocating motion; during the vertical reciprocating motion of the first rack, the transverse plate moves synchronously.

[0021] During the movement of the transverse plate, the cutting knife moves synchronously; during the movement of the cutting knife, the cutting knife can cut the frozen fish, so that the frozen fish is initially cut to prepare for subsequent further crushing, thereby enhancing the crushing effect and saving crushing time.

[0022] Furthermore, it also includes a crushing part symmetrically arranged on both sides of the cylindrical barrel along the axial direction of the cylindrical barrel; the crushing part includes a long shaft, a plurality of crushing knives, and a second gear; the long shaft is rotatably connected to the cylindrical barrel; the plurality of crushing knives are equidistantly arranged along the axial direction of the long shaft, and the crushing knives are fixedly connected to the long shaft; the second gear is fixedly connected to the long shaft, and the second gear is meshed with the second rack.

[0024] In summary, the frozen fish is first pre-processed by the crushing knife, then roughly processed by the cutting knife, and finally finely processed by the first crushing roller and the second crushing roller, thereby completing the full set of crushing process for the frozen fish, ensuring that the frozen fish can be crushed more completely and thoroughly.

During the rotation of the third gear, the third gear is engaged with the fourth gear, so the fourth gear rotates. During the rotation of the fourth gear, the second rotating shaft rotates synchronously, so the second crushing roller rotates.

[0068] When the spherical wedge block 37 moves to the position where the wedge groove 36 is located, the spherical wedge block 37, under the action of the wedge groove 36, drives the auxiliary block 11 to reset, so that the first spring 13 is compressed, thereby facilitating the auxiliary block 11 to drive the brush block 12 to move closer to the position where the screening plate 2 is located again.

[0069] During the crushing of the frozen fish, the linkage block 14 can make vertical reciprocating motion; during the movement of the linkage block 14, the throwing block 15 moves synchronously; during the movement of the throwing block 15, the throwing block 15 can drive the frozen fish particles to fly from bottom to top along the height direction of the cylindrical barrel 1 to both sides of the throwing block 15, thereby expanding the distribution range of the frozen fish, and finally falling into the cylindrical barrel 1, further ensuring that the frozen fish are more evenly distributed in the cylindrical barrel 1, thereby enhancing the crushing effect of the first crushing roller 3 and the second crushing roller 4.
