Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a crab roe extraction device. Background Art

[0002] Crab roe is the ovary and digestive gland in a crab. Due to food processing requirements, the crab roe inside the crab needs to be taken out separately. The main crab roe extraction devices include automatic crab roe adsorbing machines, crab roe separators, crab roe adsorption tanks, etc. Among them, the crab roe adsorbing machine usually uses the negative pressure extraction method to extract crab roe, so it needs to be transported through an extraction pipe.

[0003] In the process of using the existing technology, although there are many benefits, there are still the following problems. It lacks a blocking structure for the extraction pipe, resulting in the phenomenon that the residue adhering to the inner wall of the extraction pipe will aggregate and drip after use, wasting crab roe and polluting the equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a crab roe extraction device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A crab roe extraction device includes a connecting pipe, a limiting ring and a connecting rod. An extraction pipe is arranged on the outer wall of the lower end of the connecting pipe. One side of the inner wall of the connecting pipe is provided with a limiting ring. One side of the inner wall of the limiting ring is provided with a support frame. A connecting rod is movably installed inside the support frame. A connecting plate is installed on the outer wall of the lower end of the connecting rod.

[0006] When using the crab roe extraction device in this technical solution, the staff places the crab roe position of the crab at the lower end of the extraction pipe, and an external negative pressure extraction device discharges the air inside the connecting pipe, so that the inside of the connecting pipe is in a negative pressure state, causing the baffle to move vertically against the spring force until the sealing pad contacts the suction pipe, ensuring the sealing between the connecting pipe and the suction pipe, and the extraction pipe is disconnected from the baffle and connected to the connecting pipe. After that, the negative pressure extraction device can extract the crab roe through the connecting pipe and the extraction pipe. After the device stops working, the spring force drives the baffle to reset, so that the baffle and the limiting ring block the connecting pipe.

[0007] Preferably, the extraction pipe is designed in a conical shape, and the centers of the connecting pipe and the extraction pipe are in the same vertical position. The crab roe is extracted by the extraction pipe and the connecting pipe.

[0008] Preferably, a connecting cover is installed on one side of the outer wall of the connecting pipe. The other end of the connecting cover is connected to the outer wall of the extraction pipe. One side of the outer wall of the connecting cover is designed in an arc shape. The connecting cover blocks between the connecting pipe and the extraction pipe.

[0009] Preferably, a sealing gasket is fixedly attached to the outer wall of the lower end of the connecting pipe. The sealing gasket is designed in a circular ring shape, and the size of the sealing gasket is adapted to the size of the connecting pipe. The sealing gasket ensures the sealing performance between the connecting pipe and the extraction pipe.

[0010] Preferably, the connecting plate is designed in a circular shape and is located inside the extraction pipe. The diameter of the connecting plate is smaller than the inner diameter of the extraction pipe. The connecting plate can move along with the connecting rod.

[0011] Preferably, a circular-array-distributed connecting frame is installed on the outer wall of the connecting plate, and the connecting frame is connected to the inner wall of the extraction pipe. The connecting plate drives the extraction pipe to move along with the connecting rod through the connecting frame.

[0012] Preferably, a baffle is installed on the outer wall of the upper end of the connecting rod. The diameter of the baffle is larger than the inner diameter of the limiting ring, and the baffle is located above the limiting ring. The limiting ring is designed with a hollow interior. The baffle and the limiting ring shield the connecting pipe.

[0013] Preferably, a spring is arranged outside the connecting rod. The spring is located between the baffle and the support frame, and the baffle is elastically connected to the support frame through the spring. The elastic force of the spring maintains the relative stability of the position of the baffle.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: By setting the baffle, the connecting cover and the limiting ring, the present utility model achieves the effect of avoiding the waste of crab roe. The staff places the position of the crab roe of the crab at the lower end of the extraction pipe, and an external negative-pressure extraction device discharges the air inside the connecting pipe, so that the inside of the connecting pipe is in a negative-pressure state, causing the baffle to move vertically against the elastic force of the spring until the sealing gasket contacts the suction pipe, ensuring the sealing performance between the connecting pipe and the suction pipe. And the extraction pipe is disconnected from the shielding of the baffle and is connected to the connecting pipe. After that, the negative-pressure extraction device can extract the crab roe through the connecting pipe and the extraction pipe. After the device stops working, the elastic force of the spring drives the baffle to reset, so that the baffle and the limiting ring shield the connecting pipe, avoiding the outflow of the crab roe inside the connecting pipe, reducing the waste amount of the crab roe, and being able to protect the device.

Then, the negative pressure extraction device can extract the crab roe through the connecting pipe 1 and the extraction pipe 12.

[0027] Example 2: A crab roe extraction device, including a connecting pipe 1, a limiting ring 2 and a connecting rod 22.
