Description

Shrimp treatment facility in batches

Technical Field

The invention belongs to the field of shrimp processing equipment, and particularly relates to a batch shrimp processing device.

Background

The crayfish has high protein content in the body, has soft meat, is easy to digest, and is a good food for people who are weak and need to be recuperated after illness; the shrimp meat is rich in magnesium, zinc, iodine, selenium, etc., and magnesium has important regulating effect on heart activity, can protect cardiovascular system, reduce cholesterol content in blood, prevent arteriosclerosis, and dilate coronary artery, and is beneficial to preventing hypertension and myocardial infarction.

The crayfish is made into various cuisines because of the larger body size, more meat and delicious meat compared with other freshwater shrimps, and is popular. The crayfish body of crayfish can be regarded as fertilizer, and the shrimp tail can eat, therefore, when eating crayfish, the separation of shrimp body shrimp tail need be carried out, and the separation operation of traditional shrimp head shrimp tail is pure manual work, because the throughput average counts in tons usually in the mill, this process demand a large amount of manual work intensive operation. Under the market environment that the shrimp food demand market is developed vigorously, the capacity demand is higher and higher, and the corresponding food safety demand is stricter and stricter. The traditional manual production mode cannot meet the requirements of current shrimp food processing enterprises. The invention can greatly solve the problems that the labor of shrimp food processing enterprises is difficult and the food safety can not be guaranteed.

The existing crayfish processing equipment is less, if crayfish processing is carried out on mechanical equipment, such as separation of shrimp bodies and shrimp tails, the crayfish needs to be clamped by using a clamping device, most of linkage power is driven by fixed-stroke motion in the traditional mechanical clamping device, more rigid connection support is adopted, the conversion motion obtained by the connection support mode is rigid, if the size of materials to be clamped is larger or harder, two swing arms of a clamping unit can generate rigid collision with the materials in the process of moving the materials to be clamped, larger impact can be generated, the impact can damage parts in the mechanical clamping device, and in addition, if the swing arms drive elements which swing continuously after clamping the materials, the damage of the mechanical device can be increased if the continuous operation is carried out, but also reduces the service life of the mechanical clamping device.

In addition, because the crawfish is covered by a layer of hard crawfish shell and the soft crawfish meat is covered by the soft crawfish shell, if the existing ordinary clamping device is used, the crawfish can easily slide out of the clamp due to the fact that the crawfish shell is hard and slippery, and the crawfish can be crushed, so that the crawfish meat is difficult to separate from the clamp after being adhered to the clamping surface of the clamp.

The buffer spring 503 of the present invention is very important to reduce the collision damage of the components and improve the life of the mechanical clamping device 200, without the damping spring 503, the connection between the parts of the invention is also rigid, when a material with a relatively large size is clamped, a rigid collision is generated, but after the buffer spring 503 is provided, when materials with overlarge size or overlarge hardness and exceeding a set value are clamped, rigid collision among the parts such as the ejector rod 40, the connecting block 501, the guide rod 502 and the like can not be generated, this is because, when the swing arm 301 is clamped, the link block 501 elastically deforms the buffer spring 503, while the swing arm 301 and the slider 20 do not move (the elastic band of the buffer spring 503 does not move the swing arm 301 to clamp the material continuously), so that the rigid connection can be converted into the flexible connection of the buffer spring 503, and the problem of part loss caused by rigid collision is avoided.

Further, the number of the guide rods 502 is more than two, and the buffer spring 503 is respectively arranged on each guide rod 502 in a penetrating manner, so that the multi-point stress of the sliding block 20 can be ensured, and the sliding block 20 can be kept to move smoothly if the positions are arranged reasonably.

When the crayfish is processed, the crayfish can be placed on the clamping device 200, the two swing arms 301 are matched to clamp the crayfish, and in the clamping process, the contact pins 604 can pierce the shells of the crayfish and pierce the bodies of the crayfish, so that the crayfish is preliminarily fixed, and the crayfish is not easy to slip out in the process that the two swing arms 301 are continuously clamped; and the crayfish extrudes the clamping section 602 and the elastic section 603 in the clamping process, so that the clamping section 602 and the elastic section 603 are elastically deformed, after the processing is finished, the clamping device 200 moves to an inverted state, the crayfish is loosened by the two swing arms 301, the clamping section 602 and the elastic section 603 apply elasticity to enable the crayfish to be automatically ejected, and therefore the clamping process is relatively reliable in fixing and ejecting the crayfish.

After the two clamping devices 200 respectively clamp the shrimp body and the shrimp tail of the crayfish, the horizontal moving shaft 80 can drive the two clamping devices 200 to be away from each other, the automatic separation of the shrimp body and the shrimp tail can be realized in the process of being away from, the separation is convenient, then the two clamping devices 200 are close to each other, the crayfish is placed in the clamping devices, and then the separation is performed, so that the crayfish body and the shrimp tail can be quickly separated.
