Example (b):

referring to fig. 1 to 9, the present embodiment provides a shrimp shelling device, which includes a first conveyor 1, a second conveyor 2, a shell opening knife assembly 3 and a meat taking assembly 4.

The first conveying member 1 and the second conveying member 2 are both conveyor belts. The first conveying member 1 and the second conveying member 2 are arranged oppositely, and one end of the first conveying member is a conveying starting end, and the other end of the first conveying member is a conveying tail end. A conveying gap 11 is provided between the first conveying element 1 and the second conveying element 2. The width of the conveying gap 11 is equivalent to the thickness of the shrimp bodies 91 or the crawling worms to be processed, so that the shrimp bodies 91 or the crawling worms are clamped by the first conveying element 1 and the second conveying element 2 after entering the conveying gap 11 and are conveyed to the conveying tail end.

The shell opening knife assembly 3 is arranged in the conveying gap 11 in cooperation with the shrimp body 91, so that when the shrimp body 91 passes through the conveying gap 11, the shrimp shell of the shrimp body 91 is cut by the shell opening knife assembly 3. The shell opening knife assembly 3 comprises a blade which is arranged in the conveying gap 11. When the shrimp body 91 or the crawling sandworm to be processed passes through the blade along the first conveying member 1 and the second conveying member 2, the shell of the shrimp body 91 or the crawling sandworm to be processed is cut by the blade.

Get meat subassembly 4 cooperation shrimp body 91 and set up in conveying clearance 11 and lie in the shell of opening knife tackle spare 3 rear to make the shrimp shell cut the back, get meat subassembly 4 and can pick up the shrimp meat. The meat extraction assembly 4 may be a clamp. After the shrimp body 91 or the shell of the sandworm to be processed is cut open, the clamp clamps the shrimp meat. The shrimp meat and the shrimp shell are gradually separated in the process that the shrimp bodies 91 to be processed or the sandworms to climb are continuously moved along the first conveying member 1 and the second conveying member 2.

When the shrimp or the crawling sandworm shells, the shrimp body 91 is placed in the conveying gap 11. At this time, the first and second conveying

members

1 and 2 clamp the shrimp bodies 91 and convey them toward the conveying end. During the transportation of the shrimp bodies 91, the shells of the shrimp bodies 91 are cut by the shell opening knife assembly 3. Thereupon, the shrimp meat is picked up by the meat extracting assembly 4, thereby separating the shrimp meat from the shell.

In order to facilitate the separation of the shrimp meat and the shrimp shell, the shrimp is required to be frozen when being peeled, and the shell separation effect is generated by utilizing the physical property difference between the shrimp shell and the shrimp meat. Because the water content of the shrimp meat is higher than that of the shrimp shell, the shrinkage of the shrimp meat is larger than that of the shrimp shell after freezing, so that the shrimp shell and the shrimp meat are not tightly adhered together. Before freezing, the crimped shrimp body 91 or the crawling worms are straightened to keep the stretched state. So that the shell and meat separation of each shrimp body 91 or the crawling sandworm can be well carried out.

In this embodiment, two second conveying members 2 are provided. A conveying gap 11 is arranged between each of the two second conveying members 2 and the first conveying member 1. At the same time, the width of the transport gap 11 between the two second transport elements 2 and the first transport element 1 is the same.

A cutting gap 6 is provided between the two second conveying members 2. The width of the cutting gap 6 increases gradually along the transport direction of the first transport element 1. The narrower end of the cutting gap 6 is the beginning of the transport, and the other end of the cutting gap 6 is the end of the transport.

The shell opener assembly 3 comprises a first blade 31 and a second blade 32. The first blade 31 and the second blade 32 are both arranged in the cutting gap 6 and extend between the transport gaps 11. The end of the first blade 31 near the narrower part of the cutting gap 6 is connected to the end of the second blade 32 near the narrower part of the cutting gap 6 and the first blade 31 and the second blade 32 are distributed in a "V" shape. The connecting ends of the first and

second blades

31 and 32 are provided with a blade edge 33. The knife edge 33 is arranged close to the narrower end of the cutting gap 6.

The meat extraction assembly 4 comprises a meat extraction needle 41. One end of the meat-taking needle 41 is arranged in the conveying gap 11 and is positioned between the first blade 31 and the second blade 32. The other end of the meat-extraction needle 41 extends toward the wider end of the cutting gap 6 and is bent toward the second conveying member 2 side.

In use, the shrimp shell is cut open by the knife edge 33. Due to the V-shaped distribution of the first blade 31 and the second blade 32, the two sides of the cut shrimp shells are respectively broken by the first blade and the second blade 32 when the shrimp bodies 91 continue moving. The shrimp body 91 continues to move and the meat needle 41 is gradually inserted into the shrimp meat. The shrimp body 91 continues to move and the shrimp meat and shell are separated.

The first blade 31 and the second blade 32 are distributed in a V shape, so that the shrimp shells on two sides can be separated, and the meat taking needle 41 can be conveniently inserted into the shrimp meat. Simultaneously, the cutting clearance 6 is gradually increased, so that the shrimp shells can be opened towards two sides. The other end of the meat-extracting needle 41 is bent toward the second conveying member 2, that is, upwardly, which gradually bends the shrimp meat in the direction of the meat-extracting needle 41, thereby gradually separating the shrimp shell from the shrimp meat. These ensure that the shrimp shells and the shrimp meat can be better separated, and ensure the shelling effect of the shrimp shelling equipment.

In the present embodiment, the amount by which the first blade 31 extends to the conveying gap 11 and the amount by which the second blade 32 extends to the conveying gap 11 each gradually increase in the direction in which the cutting gap 6 gradually increases. The depth of the knife edge 33 cutting into the shrimp body 91 is gradually deepened, so that the shrimp shell has buffering effect when being cut, and the cutting effect is ensured. In addition, during the process of gradually breaking the two sides of the cut shrimp shells, the shrimp shells may be separated from the first and

second blades

31 and 32, thereby causing the shrimp shells not to be broken well. The amount by which the first blade 31 extends into the conveying gap 11 and the amount by which the second blade 32 extends into the conveying gap 11 both increase gradually in the direction in which the cutting gap 6 increases gradually. The shrimp shells on the two sides can be prevented from falling off, and the effect of breaking the shrimp shells off is ensured.

In this embodiment, the second conveying member 2 is hinged to the frame 7 at its end close to the narrower side of the cutting gap 6. The meat extraction assembly 4 comprises a rotating rod 42 and a telescopic rod 43. The telescopic rod 43 can be slidably inserted through the frame 7. The lower end of the telescopic rod 43 is hinged at one end of the two second conveying pieces 2. A first spring 44 is arranged between the telescopic rod 43 and the frame 7. The elastic force of the first spring 44 can push the telescopic rod 43 toward one end of the first conveying member 1. After the shrimp body 91 enters the conveying gap 11, the thrust of the first spring 44 enables the second conveying part 2 to approach the first conveying part 1, and then the shrimp body 91 is clamped, so that the shrimp body 91 can be well conveyed, and the subsequent cutting of the shrimp shell is ensured to be smoother.

One end of the rotating rod 42 is connected with the meat-taking needle 41, and the other end is rotatably connected with the frame 7 and positioned above the telescopic rod 43. The other end of the meat-extraction needle 41 extends between the conveying gaps 11. The end of the turning lever 42 connected to the frame 7 is provided with a turning shaft 424. The rotation shaft 424 protrudes into the inside of the housing 7 so that the rotation lever 42 is rotatably connected to the housing 7 through the rotation shaft 424. A torsion spring 422 is provided between the frame 7 and the rotating shaft 424.

The turning rod 42 is provided with a first wedge 421. The first wedge 421 is a semi-circular cylinder, and has an inclined top surface. The top end of the telescopic rod 43 is provided with a second wedge 431 in cooperation with the first wedge 421, and the shape of the second wedge 431 is the same as that of the first wedge 421. When the telescopic bar 43 moves upward and presses the rotating lever 42, the top surface of the first wedge 421 contacts and slides relative to the top surface of the second wedge 431, so that the rotating lever 42 rotates. The torsion spring 422 is pressed and deformed during the rotation of the rotating lever 42 pushed by the telescopic lever. So that the telescopic rod 43 can push the rotating rod 42 to rotate when ascending. A torsion spring 422 is arranged between the rotating rod 42 and the frame 7, so that when the rotating rod 42 is pushed to rotate by the telescopic rod 43, the torsion spring 422 is squeezed. After the telescopic rod 43 descends and leaves the rotating rod 42, the rotating rod 42 rotates under the action of the torsion spring 422.

After the shrimp body 91 enters the conveying gap 11, the shrimp body 91 jacks up the second conveying member 2, so that the telescopic rod 43 rises, and the rotating rod 42 rotates. In this process, the torsion spring 422 is compressed and the fleshing needle 41 follows the turning rod 42 to rotate to the space between the conveying gaps 11. The meat taking needle 41 is conveniently inserted into the shrimp meat. After the shrimp bodies 91 are completely separated from the conveying gap 11, no object exists between the first conveying member 1 and the second conveying member 2, the first spring 44 pushes the second conveying member 2 to descend, and the telescopic rod 43 descends along with the second conveying member. After the telescopic rod 43 descends to enable the telescopic rod to leave the rotating rod 42, the rotating rod 42 rotates under the action of the torsion spring 422. Thereby enabling the meat taking needle 41 to rotate and leave the conveying gap 11, and facilitating the taking off of the shrimp meat on the meat taking needle 41. The separation process of the shrimp shells and the shrimp meat is more automatic.

The first wedge 421 and the second wedge 431 are both cylindrical and semicircular. This makes the rotating rod 42 rotate at an angle of 90 degrees when the telescopic rod 43 pushes the rotating rod 42. The shrimp meat is completely separated from the conveying gap 11, so that the shrimp meat is convenient to take down. The angle of rotation of the rotating rod 42 can also be set as desired. When the wedge is installed, the angle at which the first wedge 421 and the second wedge 431 are wrapped around the cylindrical circumference may be changed.

In this embodiment, one end of the rotating rod 42 connected to the frame 7 is provided with a plurality of ratchet teeth 423. A plurality of ratchet teeth 423 are distributed in a circular ring shape. The frame 7 is provided with pawls 71 in cooperation with ratchet teeth 423. A second spring 72 is provided between pawl 71 and frame 7 to enable second spring 72 to urge pawl 71 against ratchet teeth 423. The top end of the telescopic rod 43 is further provided with a boss 432 in cooperation with the pawl 71, so that the boss 432 can push the pawl 71 to disengage from the ratchet teeth 423 when the telescopic rod 43 descends.

When the telescopic bar 43 ascends, the telescopic bar 43 pushes the rotating bar 42 to rotate. At this time, the ratchet teeth 423 rotate relative to the pawls 71. When the telescopic rod 43 descends, the second spring 72 makes the pawl 71 abut against the ratchet teeth 423, so that the ratchet teeth 423 are prevented from rotating relative to the pawl 71, and the rotating rod 42 is prevented from rotating. When the telescopic rod 43 descends to the boss 432 to press the pawl 71, the second spring 72 is pressed and deformed, the pawl 71 is disengaged from the ratchet teeth 423, and the rotating rod 42 is rotated. In practice, when the shrimp bodies 91 are transported along the transport gap 11 and only the ends thereof remain in the transport gap 11, the telescopic rod 43 extends towards the first transport member 1 under the action of the first spring 44, since the ends of the shrimp bodies 91 are thin relative to the middle thereof. Thereby separating the first wedge 421 and the second wedge 431 from each other. At this time, the rotating lever 42 still does not rotate because the pawl 71 still abuts against the ratchet teeth 423. This allows the swivelling levers 42 to swivel only when the shrimp bodies 91 are completely out of the conveying gap 11. Namely the shrimp shell and the shrimp meat are rotated after being completely separated.

In practice, the shrimp bodies 91 with different sizes may cause different opening amounts of the conveying gap 11, and thus different angles for the telescopic rod 43 to push the rotating rod 42 to rotate. In order to avoid that the meat-taking needle 41 is not rotated between the first blade 31 and the second blade 32 by rotating the rod 42 when the telescopic rod 43 is fully jacked up, the shrimp bodies 91 are classified into sizes before the shell and meat are separated. Meanwhile, the number of the ratchet teeth 423 provided to the rotating lever 42 is as large as possible. This ensures that the rotation of the rotating lever 42 by a small angle also enables the pawl 71 to correspond to one ratchet tooth 423.

In this embodiment, a guide plate 8 is further provided between the first blade 31 and the second blade 32. The guide plate 8 is bent downward. The upper end of the guide plate 8 is lower than the lower end of the meat-taking needle 41. After the shrimp meat is put through the meat needle 41, the shrimp meat is bent upward along the bending direction of the meat needle 41, so that the shrimp meat is separated from the shrimp shell. Meanwhile, the gap between the shrimp meat and the shrimp shell facilitates the guide plate 8 to enter between the shrimp shell and the shrimp meat. The shrimp bodies 91 continue to be transported with the guide plate 8 gradually extending between the shrimp shells and the shrimp bodies 91. Meanwhile, the shrimp shell is bent downwards under the action of the guide plate 8, so that the shrimp shell and the shrimp meat are better separated.

A conveyor roller 9 is also included. The feed rollers 9 are provided in cooperation with the feed end of the first conveying member 1 and the lower end of the guide plate 8 so that the shrimp shells guided by the guide plate 8 are pinched by the feed end of the first conveying member 1 and the feed rollers 9. And then make first conveying member 1 and conveying roller 9 carry the shrimp shell forward, avoid the shrimp body 91 to break away from behind conveying clearance 11 the shrimp body 91 and lose the impetus and lead to the shrimp body 91 and the complete separation of shrimp shell.

In this embodiment, the device further comprises a feeding device 5. The feeding device 5 includes a base 55, a material selecting plate 51, and a rotating disk 52. The material selecting plate 51 is obliquely arranged above the base 55. The rotating disc 52 is rotatably fitted around the exterior of the material selecting plate 51 so that the rotating disc 52 can rotate around the material selecting plate 51. A material selecting motor 53 is arranged in the base 55, and a driving gear 54 is arranged on a motor shaft of the material selecting motor. Correspondingly, the rotary disc 52 is provided with teeth in cooperation with the driving gear 54. The material selecting motor 53 can drive the rotating disc 52 to rotate through the driving gear 54. The inner side wall of the rotating disc 52 is provided with a stirring plate 521, so that the material in the rotating disc 52 can move along with the stirring plate 521.

The material selecting groove 514 is provided on the upper plate surface of the material selecting plate 51 along the inclination direction of the material selecting plate 51. The width of the material selecting groove 514 is wider than the diameter of the shrimp body 91 or the crawling sandworm, and the width of the material selecting groove 514 is wider at the top and narrower at the bottom. When the shrimp bodies 91 move to the upper part of the material selecting groove 514 along the stirring plate 521, the shrimp bodies 91 roll down to the material selecting groove 514 along the stirring plate 521. If the longitudinal direction of the shrimp bodies 91 is not consistent with the extending direction of the material selecting groove 514, the shrimp bodies 91 may not enter the material selecting groove 514, but slide to the bottom of the rotating disc 52 at the top of the two opposite sides of the material selecting groove 514, and are lifted up above the material selecting plate 51 by the rotating disc 52 again. If the longitudinal direction of the shrimp body 91 coincides with the extending direction of the sorting chute 514, the shrimp body 91 can enter the sorting chute 514 and slide down along the sorting chute 514. Since the upper portion of the sorting chute 514 is wide, if the longitudinal direction of the shrimp body 91 slightly differs from the extending direction of the sorting chute 514, the shrimp body 91 can enter the sorting chute 514 and slide down along the sorting chute 514. In the process that the shrimp bodies 91 slide down along the material selecting groove 514, the shrimp bodies 91 gradually accord with the extending direction of the material selecting groove 514 under the action of the material selecting groove 514.

The upper plate surface of the material selecting plate 51 is provided with a plurality of material passing holes 511 in the material selecting groove 514. The size of the material passing hole 511 is slightly larger than the diameter of the shrimp body 91 or the crawling sandworm. If the length direction of the shrimp bodies 91 or the sandworms is consistent with the extending direction of the material selecting groove 514, the shrimp bodies 91 or the sandworms can enter the material passing holes 511.

The interior of the material selecting plate 51 is provided with a material channel 512 communicated with the material passing hole 511. The lower end of the material channel 512 is communicated to the conveying gap 11. After the shrimp bodies 91 or the sandworms enter the material channel 512 through the material passing holes 511, the shrimp bodies 91 or the sandworms flow to the conveying gap 11 along the material channel 512.

These settings just make the shrimp body 91 or climb sandworm and can flow to conveying gap 11 along the direction of needs, guarantee to open the shell effect, and then guarantee the effect of shrimp shell and shrimp meat separation.

In this embodiment, a ventilation duct 513 is further disposed inside the material selecting plate 51. The wall of the vent pipeline 513 is provided with a vent hole communicated with the material channel 512. The vent pipe 513 can introduce high-pressure gas into the material passage 512 and can also extract gas to form negative pressure in the material passage 512. Negative pressure is formed in the material channel 512, so that the shrimp bodies 91 at the material passing holes 511 can be sucked into the material channel 512.
