Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a mechanical separation device for separating sea cucumber seeds and fertilized eggs during the spawning process of sea cucumbers. Background Technique

[0002] Sea cucumbers belong to the class Holothuroidea and are marine echinoderms living from the seashore to 8000 meters. They have a history of more than 600 million years. Sea cucumbers feed on undersea algae and plankton. Sea cucumbers have extremely high nutritional value and are deeply loved by people. Therefore, sea cucumber farming is also increasing. During the breeding of sea cucumbers, in order to improve the reproductive ability, during the spawning process of sea cucumbers, centralized treatment is required. After spawning, it is necessary to separate the sea cucumber seeds and sea cucumber eggs. There is a mechanical separation device for separating sea cucumber seeds and fertilized eggs during the spawning process of sea cucumbers with the publication number of CN 216292622 U. The sea cucumber seeds are placed on the filter screen. After spawning is completed, the output shaft of the driving power motor rotates, driving the double-headed threaded rod to rotate, thereby driving the two threaded sleeves to move towards both ends, causing the two rotating plates to rotate, driving the support plate to move downward, and causing the collection plate to move downward, realizing the separation of sea cucumber seeds and sea cucumber eggs, avoiding manual separation and easily causing damage to the sea cucumber seeds. Pull the handle to open the box door and pull the collection plate out of the box body to collect the sea cucumber eggs. However, the above device only places the sea cucumber seeds on the filter screen and allows the sea cucumber eggs to fall. During the separation process, the separation of the sea cucumber eggs is not thorough and the separation efficiency is low. Content of the Utility Model

[0003] The purpose of the utility model is to provide a mechanical separation device for separating sea cucumber seeds and fertilized eggs during the spawning process of sea cucumbers to solve the above problems.

[0004] The utility model realizes the above purpose through the following technical solutions:

[0005] A mechanical separation device for separating sea cucumber seeds and fertilized eggs during the spawning process of sea cucumbers includes a support mechanism for providing a separation cavity. A separation mechanism for vibrating and separating sea cucumber seeds and fertilized eggs is arranged on the support mechanism, and a collection box for receiving sea cucumber eggs is arranged below the separation mechanism;

[0006] The support mechanism includes a box body with an opening at the front side. A separation cavity is arranged inside the box body, and grooves are oppositely arranged on both sides of the inner wall of the cavity;

[0007] The separation mechanism includes a support plate arranged parallel to the bottom of the cavity. A through hole is opened in the center of the support plate, and a filter screen is arranged on the through hole. A retaining frame is arranged on the upper end of the support plate around the filter screen. Springs are arranged at the four corners of the lower end of the support plate. A power assembly for pushing the support plate to move up and down is arranged below the support plate.

[0008] Further setting: The power assembly includes a rotating shaft disposed on the lower side of the support plate, a cam is disposed on the rotating shaft, and one end of the rotating shaft is connected to a motor.

[0009] Further setting: The rotating shaft is rotatably connected to the box body, and there are two fixed cams on the rotating shaft.

[0010] Further setting: Both ends of the spring are fixedly connected to the support plate and the bottom of the groove respectively.

[0011] Further setting: The support plate is slidably connected to the box body, the collection box is slidably connected to the box body, and the area of the collection box is larger than the area of the filter screen.

[0012] Further setting: A box door is rotatably connected to the front end of the box body, and an observation window is provided on the box door.

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

[0014] Through the setting of the separation mechanism, the motor works to drive the rotating shaft and the cam to rotate. As the cam rotates, the support plate is pushed upward. At the same time, the spring tightens the support plate from the lower side, causing the support plate to fluctuate up and down. The sea cucumber eggs on the filter screen fall through the filter screen during the up and down fluctuations, which improves the efficiency of sea cucumber egg separation.
