Description

Technical Field

[0001] The utility model belongs to the technical field of shrimp shell peeling, and particularly relates to a shrimp shell peeling device. Background Art

[0002] The shrimp head contains heavy metals which are harmful to the human body. When people eat, they need to remove the heads of prawns. The head removal of prawns is an important process in automatic shelling equipment. The existing shrimp shelling equipment mainly removes the heads by positioning the shrimp body and then cutting.

[0003] After retrieval, the publication number: CN212787277U discloses a shrimp head removal device. In the present utility model, the conveyor belt conveys the shrimp body with the head facing the conveying direction and the shrimp back facing up into the U-shaped channel of the clamping frame. The shrimp body is straightened by the clamping and squeezing of the conveyor belt and passes through the decapitation wheel that can freely float up and down and rotate. Because the linear velocity of the peeling teeth is greater than the conveying velocity of the conveyor belt, during the rotation of the peeling teeth, the edges of the shrimp head shell can be caught or hooked, and the shrimp head shell can be quickly scraped off the shrimp body to achieve the effect of head removal and retain the shrimp head meat. However, this device only retains the head removal operation, but for the shelling of the shrimp tail part, this device does not have relevant structures, so manual peeling is still required, and the operation is troublesome.

[0004] Therefore, a shrimp shell peeling device is designed to solve the above problems. Content of the Utility Model

[0005] To solve the problems raised in the above background art, the utility model provides a shrimp shell peeling device. When the device is in use, the clamping arm body is installed inside the inclined plate frame. Shrimp can be placed on the belt of the belt conveyor. As the shrimp is transported outwards until the outside of the support frame, two groups of electric telescopic rods in operation push the connecting rod, and the connecting rod pushes two groups of push blocks to approach each other relatively, and keeps the shrimp in the middle of the belt. The clamping arm body is controlled by hydraulic pressure, and the vise of the clamping arm body abuts against the shrimp tail. At the same time, the high-frequency rotating cutting blade cuts off the shrimp head. The clamping arm body puts down the shrimp tail. Under the belt transmission, the shrimp tail slides along the sliding table into the feed inlet of the cooling box body and lands on the storage plate. After collecting a large number of shrimp tails, cover the top sealing cover of the cooling box body, turn on the power supply and freeze the shrimp tails, and control the freezing time to be 1-2 hours, which is convenient for subsequent shrimp tail peeling and also ensures the freshness of the shrimp tail meat.

[0006] When cutting the head, the driving shaft is driven by an electric motor to rotate the large belt pulley. Under the traction effect of the transmission belt, the small belt pulley on the outside drives the guide shaft, the rotating shaft, and the outermost cutting blade to rotate at an increased speed, ensuring the cutting effect. After the freezing is completed, the cover plate is opened, and the shrimp tails on the storage plate are taken out and put into the inside of the tailing box. The stepping motor on the outside is started through the control terminal. The stepping motor drives the connecting shaft to rotate, and the connecting shaft drives the positioning frame and the knocking plate to rotate cyclically, so that the shrimp tails laid flat inside come into frequent contact with the knocking plate. Under the continuous throwing effect, the frozen shrimp tails and the shrimp meat are quickly removed, thus eliminating the manual operation process of removing shrimp tails and effectively improving the production efficiency of this device.

[0007] To achieve the above object, the present utility model provides the following technical solutions: A shrimp shell peeling device, including a freezing and peeling mechanism.

The sliding table is fixedly connected to the outside of the bottom of the belt conveyor. The cooling box body is arranged at the lower end of the sliding table. The head-cutting component is arranged on the side of the sliding table away from the belt conveyor. The tailing box is arranged on the outside of the belt conveyor.

[0008] As a preferred embodiment of the shrimp shell peeling device of the present utility model, the head-cutting component includes a protective cover, an electric motor, a driving shaft, a guide shaft, a large belt pulley, a small belt pulley, a rotating shaft, and a cutting blade. The electric motor is threadedly connected to the lower end of the protective cover. The outside of the driving shaft is fixedly connected to the middle of the large belt pulley. The middle of the small belt pulley is fixedly connected to the top of the guide shaft. The rotating shaft is fixedly connected to the outside of the small belt pulley.

[0009] As a preferred embodiment of the shrimp shell peeling device of the present utility model, a transmission belt is also closely attached to the outside of the large belt pulley and the small belt pulley.

[0010] As a preferred embodiment of the shrimp shell peeling device of the present utility model, a stepping motor, a connecting shaft, a positioning frame, and a knocking plate are also arranged inside the tailing box. The motor shaft of the stepping motor is fixedly connected to one end of the connecting shaft through a coupling. The positioning frame is sleeved on the outside of the connecting shaft. The knocking plates are annularly arranged on the outside of the positioning frame.

[0011] As a preferred embodiment of the shrimp shell peeling device of the present utility model, a cover plate and a storage plate are also arranged on one side of the cooling box body. The cover plate is snap-connected to the outside of the bottom of the cooling box body. The storage plate is slidably connected to the inside of the cooling box body.

The output end of the electric telescopic rod is fixedly connected to one end of the connecting rod, and the outer side of the connecting rod is fixedly connected to the surface of the push block.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the two operating electric telescopic rods push the connecting rod, and the connecting rod pushes the two push blocks to approach relatively, and holds the shrimp in the middle of the belt. By hydraulically controlling the clamping arm body, the vise of the clamping arm body abuts against the shrimp tail. The high-frequency rotating cutting blade cuts off the shrimp head. The clamping arm body puts down the shrimp tail. Under the belt transmission, the shrimp tail slides along the sliding table into the feeding port of the cooling box and lands on the storage plate. After collecting a large number of shrimp tails, cover the top sealing cover of the cooling box, turn on the power and freeze the shrimp tails, and control the freezing time to be 1-2 hours, which not only facilitates the subsequent peeling of the shrimp tails, but also ensures the fresh meat quality of the shrimp tails.

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 shown:

[0027] A shrimp shell peeling device. As known from CN212787277U, the shrimp body is straightened by the clamping and squeezing of the conveyor belt and passes through a head-removing wheel that can freely float up and down and rotate. Since the linear velocity of the peeling teeth is greater than the conveying velocity of the conveyor belt, during the rotation of the peeling teeth, the edges of the shrimp head shell can be caught or hooked, and the shrimp head shell can be quickly scraped off the shrimp body, achieving the effect of removing the head and retaining the shrimp head meat. However, this device only retains the head-removing operation, but for the shell peeling of the shrimp tail part, this device does not have relevant structures, so manual peeling is still required, which is troublesome. On this basis, the freezing and peeling mechanism 1 is added.

[0028] As Figure 1 、 Figure 2 and Figure 4 shown:

[0029] In an alternative embodiment: The freeze-type peeling mechanism 1 includes a belt conveyor 11, a support frame 12, an inclined plate frame 13, a clamping arm body 14, a sliding table 15, a cooling box body 16, a tail-removing box 17, and a head-removing assembly 18. The top of the belt conveyor 11 is fixedly connected to the bottom surface of the support frame 12. The outer side of the inclined plate frame 13 is threadedly connected to the top of the clamping arm body 14. The sliding table 15 is fixedly connected to the outer side of the bottom of the belt conveyor 11. The cooling box body 16 is arranged at the lower end of the sliding table 15. The head-removing assembly 18 is arranged on the side of the sliding table 15 away from the belt conveyor 11. The tail-removing box 17 is arranged on the outer side of the belt conveyor 11. A transmission belt 2 is also closely attached to the outer sides of the large belt pulley 185 and the small belt pulley 186. A cover plate 7 and a storage plate 8 are also arranged on one side of the cooling box body 16. The cover plate 7 is snap-connected to the outer side of the bottom of the cooling box body 16. The storage plate 8 is slidably connected to the inside of the cooling box body 16.

[0030] In this implementation: The clamping arm body 14 is installed inside the inclined plate frame 13. Shrimp can be placed on the belt of the belt conveyor 11. As the shrimp are transported outwards until the outside of the support frame 12, two operating electric telescopic rods 20 push the connecting rod 21. The connecting rod 21 pushes two push blocks 22 to move relatively closer and hold the shrimp in the middle of the belt. The clamping arm body 14 is hydraulically controlled to make the vise of the clamping arm body 14 abut against the shrimp tails. At the same time, the high-frequency rotating cutting blade 188 cuts off the shrimp heads. The clamping arm body 14 puts down the shrimp tails. Under the belt transmission, the shrimp tails slide along the sliding table 15 into the feed inlet of the cooling box body 16 and land on the storage plate 8. After collecting a large number of shrimp tails, cover the top sealing cover of the cooling box body 16, turn on the power and freeze the shrimp tails, and control the freezing time to be 1 - 2 hours, which not only facilitates the subsequent peeling of the shrimp tails but also ensures the freshness of the shrimp tail meat.

[0031] Furthermore:

[0032] As Figure 3 、 Figure 5 and Figure 6 shown:

[0033] In an alternative embodiment: The head-removing assembly 18 includes a protective cover 181, a motor 182, a drive shaft 183, a guide shaft 184, a large pulley 185, a small pulley 186, a rotating shaft 187, and a cutting blade 188. The motor 182 is threadedly connected to the lower end of the protective cover 181. The outer side of the drive shaft 183 is fixedly connected to the middle of the large pulley 185. The middle of the small pulley 186 is fixedly connected to the top of the guide shaft 184. The rotating shaft 187 is fixedly connected to the outer side of the small pulley 186. The cutting blade 188 is welded and fixed to the outer wall surface of the rotating shaft 187. Inside the tail-removing box 17, there are also a stepper motor 3, a connecting shaft 4, a positioning frame 5, and a knocking plate 6. The motor shaft of the stepper motor 3 is fixedly connected to one end of the connecting shaft 4 through a coupling. The positioning frame 5 is sleeved on the outer side of the connecting shaft 4. The knocking plates 6 are arranged in a circular array on the outer side of the positioning frame 5. On both sides of the support frame 12, there are also electric telescopic rods 20, connecting rods 21, and pushing blocks 22. The output end of the electric telescopic rod 20 is fixedly connected to one end of the connecting rod 21. The outer side of the connecting rod 21 is fixedly connected to the surface of the pushing block 22.

[0034] In this embodiment: When cutting the head, the motor 182 drives the drive shaft 183 to rotate the large pulley 185. Under the traction effect of the transmission belt 2, the outer small pulley 186 can drive the guide shaft 184, the rotating shaft 187, and the outermost cutting blade 188 to rotate at an increased speed, ensuring the cutting effect. After the freezing is completed, the cover plate 7 is opened, and the shrimp tails on the storage plate 8 are taken out and put into the interior of the tail-removing box 17. The outer stepper motor 3 is started through the control terminal. The stepper motor 3 drives the connecting shaft 4 to rotate. The connecting shaft 4 drives the positioning frame 5 and the knocking plates 6 to rotate in a cycle, making the shrimp tails laid flat inside come into frequent contact with the knocking plates 6. Under the continuous effect of throwing the materials, the rapid removal of frozen shrimp tails and the shrimp meat is completed, thus eliminating the manual operation process of removing shrimp tails and effectively improving the production efficiency of this device.

[0035] Finally, it should be noted that: The above are only the preferred embodiments of the present invention and are not used to limit the present invention.
