Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to an automatic fish egg separation and cleaning device for aquaculture. Background Technology

[0002] With the large-scale and intensive development of aquaculture, fish egg hatching and seedling raising are core links in the industrial chain, and their quality directly affects the subsequent aquaculture benefits. Fish eggs are prone to being covered with impurities (such as algae, mud, and decaying matter) and mucus during collection, transportation, and storage. If they are not thoroughly cleaned, it may lead to abnormal embryonic development, disease transmission, and a decrease in hatching rate.

[0003] Traditional fish egg cleaning and separation methods mainly rely on manual washing or simple mechanical vibration screening, which are prone to some problems. First, manual operation depends on experience, is time-consuming, and it is difficult to ensure the accuracy of fish egg separation and thorough cleaning, which is difficult to meet the needs of large-scale aquaculture. At the same time, the impact generated by mechanical vibration can easily damage fish eggs and reduce the hatching rate. Utility Model Content

[0004] To overcome the problems of unsatisfactory separation and cleaning effects of traditional fish egg cleaning and separation methods, and the potential for damage to fish eggs due to the impact generated, an automatic fish egg separation and cleaning device for aquaculture is proposed.

[0005] The technical solution is as follows: An automatic fish egg separation and cleaning device for aquaculture includes a cleaning tank, and a fish egg placement tank mechanism that separates fish eggs from impurities and mucus after operation is placed inside the cleaning tank. The fish egg placement tank mechanism includes an outer cylinder and an inner cylinder. The inner cylinder is welded to the inner side of the outer cylinder. Large filter holes are opened on the outer surface of the inner cylinder, and small filter holes are opened on the outer surface of the outer cylinder. A positioning seat A is fixedly connected to the lower end of the fish egg placement tank mechanism. A rotating motor is installed at the lower end of the cleaning tank. A positioning seat B is installed at the upper end of the output shaft of the rotating motor. The positioning seat A and the positioning seat B are fitted together. A lifting mechanism for controlling the rising and falling of the fish egg placement tank mechanism is welded to the left end of the cleaning tank. A limiting clamping mechanism for holding the fish egg placement tank mechanism is fixedly connected to the left end of the lifting mechanism.

[0006] Furthermore, the rear end of the cleaning tank is connected to a discharge channel for discharging wastewater and impurities, and both the cleaning tank and the fish egg placement tank are circular structures.

[0007] Furthermore, a cross-shaped groove is provided at the lower end of positioning seat A, and a cross-shaped block is welded to the upper end of positioning seat B. The cross-shaped groove and the cross-shaped block are fitted together.

[0008] Furthermore, the lifting mechanism includes a mounting frame, a drive motor, a threaded rod, a threaded sleeve, a limiting structure, and a connecting arm. The mounting frame is fixed to the left end of the cleaning tank, the drive motor is mounted on the upper end of the mounting frame, and the threaded rod is mounted on the lower end of the output shaft of the drive motor.

[0009] Furthermore, a threaded sleeve is connected to the outer side of the threaded rod. An "L"-shaped connecting arm is welded to one end of the threaded sleeve near the fish egg placement bucket mechanism. A limiting structure consisting of a long groove and a slider is provided between the mounting frame and the threaded sleeve. A long groove is opened through the mounting frame in the vertical direction. A slider that slides with the long groove is fixedly connected to the outer side of the threaded sleeve. The slider is embedded in the inner side of the long groove.

[0010] Furthermore, the limiting clamping mechanism includes a limiting frame, a cylinder assembly, a sliding arm, a clamping ring, and a limiting plate. The lifting mechanism is fixedly connected to the limiting frame at one end near the fish egg placement bucket mechanism. A cylinder assembly is installed on the upper end of the limiting frame, and a sliding arm is fixedly connected to the output end of the cylinder assembly. The sliding arm is located inside the limiting frame and the two are slidably connected.

[0011] Furthermore, a clamping ring is fixedly connected to the right end of the sliding arm, and two annular limiting plates are welded to the outside of the cleaning tub. The limiting plates are symmetrical about the clamping ring.

[0012] The beneficial effects are as follows: This utility model can achieve rapid and precise clamping of the fish egg placement bucket mechanism through the limiting clamping mechanism. With the help of the lifting mechanism, the fish egg placement bucket mechanism is controlled to descend stably to the designated position inside the cleaning bucket. After cleaning, the lifting mechanism can be reversed to quickly lift the fish egg placement bucket mechanism, which is convenient for workers to disassemble and transfer fish eggs. When the fish egg placement bucket mechanism is driven to rotate by the rotating motor, the fish eggs and impurities and mucus are efficiently separated under the action of centrifugal force. The graded design of large and small filter holes allows high-quality fish eggs to be retained in the inner cylinder, while smaller fish eggs are temporarily stored in the cavity between the outer and inner cylinders. Impurities and mucus are discharged through the small filter holes, realizing the fine screening and separation of fish eggs and greatly reducing the fish egg breakage rate.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-5 As shown, this utility model provides an embodiment: an automatic fish egg separation and cleaning device for aquaculture, including a cleaning tank 1, and a fish egg placement tank mechanism placed inside the cleaning tank 1 to separate fish eggs from impurities and mucus after operation. The fish egg placement tank mechanism includes an outer cylinder 201 and an inner cylinder 202. The inner cylinder 202 is welded to the inner side of the outer cylinder 201. A large filter hole 203 is opened on the outer surface of the inner cylinder 202, and a small filter hole 204 is opened on the outer surface of the outer cylinder 201. A positioning seat A3 is fixedly connected to the lower end of the fish egg placement tank mechanism. A rotating motor 4 is installed at the lower end of the cleaning tank 1. A positioning seat B5 is installed at the upper end of the output shaft of the rotating motor 4. The positioning seat A3 and the positioning seat B5 are fitted together. A lifting mechanism for controlling the rising and falling of the fish egg placement tank mechanism is welded to the left end of the cleaning tank 1. A limiting clamping mechanism for holding the fish egg placement tank mechanism is fixedly connected to the left end of the lifting mechanism.

[0017] Please see Figure 2 In this embodiment, the rear end of the cleaning tank 1 is connected to a discharge channel 10 for discharging wastewater and impurities. Both the cleaning tank 1 and the fish egg placement tank mechanism are circular structures.

[0018] Please see Figure 3 , 5 In this embodiment, the limiting clamping mechanism includes a limiting frame 701, a cylinder assembly 702, a sliding arm 703, a clamping ring 704, and a limiting plate 705. The lifting mechanism is fixedly connected to the limiting frame 701 at one end near the fish egg placement bucket mechanism. The cylinder assembly 702 is installed on the upper end of the limiting frame 701. The output end of the cylinder assembly 702 is fixedly connected to the sliding arm 703. The sliding arm 703 is located inside the limiting frame 701 and the two are slidably connected. The right end of the sliding arm 703 is fixedly connected to the clamping ring 704. Two annular limiting plates 705 are welded to the outside of the cleaning bucket 1. The limiting plates 705 are symmetrical about the clamping ring 704. The cylinder assembly 702 of the limiting clamping mechanism drives the sliding arm 703 to cooperate with the clamping ring 704 to achieve fast and accurate clamping of the fish egg placement bucket mechanism.

[0019] Please see Figure 4 In this embodiment, the lifting mechanism includes a mounting frame 601, a drive motor 602, a threaded rod 603, a threaded sleeve 604, a limiting structure 605, and a connecting arm 606. The mounting frame 601 is fixed to the left end of the cleaning tank 1. The drive motor 602 is mounted on the upper end of the mounting frame 601. The threaded rod 603 is mounted on the lower end of the output shaft of the drive motor 602. The threaded sleeve 604 is connected to the outer side of the threaded rod 603. An "L"-shaped connecting arm 606 is welded to the end of the threaded sleeve 604 near the fish egg placement tank mechanism. The mounting frame 601 and the threaded sleeve 604 are connected... A limiting structure 605 consisting of a long groove and a slider is provided. The mounting bracket 601 has a long groove running through it in the vertical direction. A slider that slides in cooperation with the long groove is fixedly connected to the outside of the threaded sleeve 604. The slider is embedded in the inside of the long groove. The lifting mechanism, through the transmission of the threaded rod 603 and the threaded sleeve 604, combined with the linear guidance of the limiting structure 605, ensures that the fish egg placement bucket mechanism is stably lowered to the designated position in the cleaning bucket 1. After cleaning, the lifting mechanism can quickly lift the fish egg placement bucket mechanism by reversing its rotation, which is convenient for staff to disassemble and transfer the fish eggs.

[0020] Please see Figure 5 In this embodiment, a cross-shaped groove 8 is provided at the lower end of the positioning seat A3, and a cross-shaped block 9 is welded to the upper end of the positioning seat B5. The cross-shaped groove 8 and the cross-shaped block 9 are fitted together. The fitting design of the cross-shaped groove 8 and the cross-shaped block 9 further enhances the positioning accuracy and avoids unsuccessful cleaning and separation due to offset.

[0021] When using this cleaning device, first place the empty fish egg placement bucket mechanism on the side of the lifting mechanism, and the limiting clamping mechanism stably clamps the fish egg placement bucket mechanism. Then, carefully place the fish eggs that need to be cleaned into the inner cylinder 202 of the fish egg placement bucket mechanism, and inject clean water into the cleaning bucket 1. When the lifting mechanism is activated, the fish egg placement bucket mechanism will be driven into the cleaning bucket 1. The drive motor 602 of the lifting mechanism drives the threaded rod 603 to rotate in the forward direction. The threaded rod 603 drives the threaded sleeve 604 to move downward. The threaded sleeve 604 moves in conjunction with the connecting arm 606, and the fish egg placement bucket mechanism also descends accordingly. During operation, the limiting structure 605 ensures that the threaded sleeve 604 moves in a straight line to avoid deviation. After descending to the appropriate position in the cleaning tub 1, the cross-shaped groove 8 of the positioning seat A3 and the cross-shaped block 9 of the positioning seat B5 are engaged and connected, which ensures that the fish egg placement tub mechanism is stably installed on the rotating motor 4. The limiting clamping mechanism releases its grip on the fish egg placement bucket mechanism. The cylinder assembly 702 of the limiting clamping mechanism drives the sliding arm 703 to slide within a small area of ​​the limiting frame 701, thereby causing the clamping ring 704 to release the fish egg placement bucket mechanism. Start the rotating motor 4, which drives the positioning seat B5 to rotate. At the same time, the fish egg placement bucket mechanism installed at the upper end rotates inside the cleaning bucket 1. During the rotation, the fish eggs and impurities and mucus gradually separate under the action of centrifugal force. The high-quality fish eggs are left in the inner cylinder 202 space, while the smaller fish eggs pass through the large filter hole 203 and are left in the cavity between the outer cylinder 201 and the inner cylinder 202. The impurities and mucus are discharged into the cleaning bucket 1 through the small filter hole 204. During the rotation of the fish egg placement bucket mechanism, the limiting plate 705 and the slightly loosened clamping ring 704 ensure the stability of the rotation of the fish egg placement bucket mechanism. After cleaning, the clamping mechanism is restored and the lifting mechanism is reversed to lift the fish egg placement tank mechanism. The staff removes the fish egg placement tank mechanism and processes the fish eggs. The wastewater and impurities in the cleaning tank 1 are discharged through the discharge channel 10.
