Description

Technical Field

[0001] This utility model relates to the field of bass manure cleaning technology, and in particular to a fish manure cleaning device for bass farming. Background Technology

[0002] Fish feces contain a large amount of organic matter and nutrients, such as nitrogen and phosphorus. If fish feces are not cleaned up in time, they will decompose in the water, leading to an increase in the content of harmful substances such as ammonia nitrogen and nitrite. These substances will have a negative impact on the growth and health of bass, and may even cause fish poisoning and death.

[0003] Therefore, the existing fish waste negative pressure cleaning device at the bottom of the breeding pond, with the publication number CN220859234U, uses a motor to drive a threaded rod to rotate, which in turn moves a second sliding plate. The rotation of the first gear drives the rotation of the second gear, the first transmission shaft, and the third gear, which in turn drives the ring rack to move. This, in turn, drives the slider and the first connecting rod to reciprocate, causing the first sliding plate to reciprocate. This reciprocating motion of the first sliding plate, in turn drives the vacuum pump and the water pipe to reciprocate, thus cleaning the entire bottom of the breeding pond.

[0004] However, if the suction nozzle of the water pipe is too large, the negative pressure is too high, and the bass is small (such as juvenile fish), the suction may cover the area where the fish are active, causing the bass to be accidentally sucked in. Alternatively, improper operation when manually adjusting the position of the water pipe during cleaning, causing the suction nozzle to be directly close to the bass, may also cause the problem of accidental suction. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a fish manure cleaning device for sea bass farming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fish manure cleaning device for sea bass farming, comprising a pump pipe for connecting to the air inlet of a vacuum pump and a pump head connected to the inlet of the pump pipe. A gravity frame is inserted into the inner wall of the pump head inlet, and a grid frame is inserted into the inner wall of the gravity frame. A coaxially arranged reel is rotatably connected to the outer wall of the pump head outlet, and a protective cover for surrounding the reel is fixedly installed on the outer wall of the pump head outlet. A plurality of traction ropes arranged in a circular array are arranged through the outer wall of the protective cover. One end of the traction rope passes through the surface of the pump head and extends inward to connect with the top of the gravity frame. The other end of the traction rope is wound around the reel. A tap for sucking up fish manure is movably installed inside the pump head.

[0007] Preferably, the pump head is provided with a cross slide, the X-axis slide of the cross slide is fixedly connected to the top surface inside the pump head, and the Y-axis slide of the cross slide is movably connected to the slider part of the X-axis slide, and the slider part of the Y-axis slide is used to install a tap.

[0008] Preferably, the X-axis slide block surface of the cross slide is fixedly mounted with a downwardly extending electric telescopic rod, and the telescopic end of the electric telescopic rod is fixedly connected to the Y-axis slide surface.

[0009] Preferably, the X-axis slide of the cross slide is arranged along the length direction of the pump head, and the Y-axis slide of the cross slide is arranged along the width direction of the pump head, with both ends of the Y-axis slide of the cross slide slidably connected to the inner wall of the grid frame.

[0010] Preferably, a piston cylinder is fixedly installed on the inner wall of the pump pipe, a piston ring is slidably installed inside the piston cylinder, and a flexible hose is provided between the inner edge of the bottom end of the piston ring and the tap.

[0011] Preferably, a plurality of spring rods are fixedly installed at the bottom of the inner wall of the piston cylinder. The spring rods are arranged parallel to the central axis of the piston cylinder and the telescopic ends of the spring rods are fixedly connected to the outer side of the bottom end of the piston ring.

[0012] Preferably, one pair of outer sides of the pump head are each inserted with a plate, and electric rollers are installed on both sides of the bottom edge of the plate. The other pair of outer sides of the pump head are each fixedly installed with an electric push rod. The telescopic end of the electric push rod faces downward and is fixedly installed with a connecting frame connected to the two plates. A connecting arm is fixedly installed on the top edge of the plate. The connecting arm is inverted U-shaped and one end of the connecting arm penetrates the surface of the pump head and is fixedly connected to the top edge of the grid frame.

[0013] Preferably, the bottom edge of the winding reel is toothed, and the pump head surface is provided with a spur gear inside the protective cover, which is driven by a motor and meshes with the toothed portion on the winding reel.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by lowering the grid frame synchronously with the insert plate and contacting the bottom of the pool, the bass under the pump head can be actively pushed away from the extraction area, reducing the possibility of fish entering the suction range of the pump head from the source. When extracting, the gravity frame automatically lowers to block the grid frame around the perimeter, filling the gaps in the grid and preventing small or juvenile fish from being sucked in from the side, forming a double protection of "grid plus gravity frame".

[0015] 2. In this utility model, when the tap moves away from the piston cylinder, it will pull the piston ring through the hose to overcome the thrust of the spring rod and descend; if it moves closer to the piston cylinder, the spring rod will elastically reset and push the piston ring upward, ensuring that the hose is always taut and avoiding the impact of hose slack on the extraction efficiency.

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] like Figures 1-4As shown, a fish manure cleaning device for sea bass farming includes a pump pipe 1 connected to the air inlet of a vacuum pump and a pump head 2 connected to the inlet of the pump pipe 1. In use, the pump pipe 1 is connected to the vacuum pump via a flexible tube, and the pump head 2 is lowered to the bottom of the aquaculture pond. A vacuum pump can be installed on a ship, and the vacuum pump and pump head 2 can be moved along the bottom of the pond. During this movement, the cooperation of the vacuum pump and pump head 2 extracts fish manure from the bottom of the pond. A gravity frame 1 is inserted into the inner wall of the pump head 2's inlet. 0. A grid frame 11 is inserted into the inner wall of the gravity frame 10. A coaxially arranged reel 15 is rotatably connected to the outer wall of the pump head 2 outlet. A protective cover 3 for surrounding the reel 15 is fixedly installed on the outer wall of the pump head 2 outlet. Several traction ropes 4 arranged in a circular array are arranged through the outer wall of the protective cover 3. One end of the traction rope 4 passes through the surface of the pump head 2 and extends inward to connect with the top of the gravity frame 10. The other end of the traction rope 4 is wound around the reel 15. The bottom edge of the reel 15 is toothed. The surface of pump head 2 is located inside the protective cover 3 and is equipped with a spur gear 16 driven by a motor and meshing with the toothed ring part of the reel 15. A tap 13 for sucking fish feces is movably installed inside pump head 2. In order to prevent the bass inside from entering under pump head 2 during the movement of pump head 2 at the bottom of the aquaculture pond, the grid frame 11 is lowered to contact the bottom of the aquaculture pond so that pump head 2 can rise to a point where it does not contact the fish feces at the bottom of the pond. This avoids scraping fish feces during the movement of pump head 2. The grid frame 11 can be used to push the bass away from under pump head 2 to prevent the bass from entering under pump head 2. When the tap 13 moves inside pump head 2 to suck fish feces, in order to prevent the suction from adhering the bass to the surface of grid frame 11, the spur gear 16 is driven to rotate by a waterproof motor installed on pump head 2. Under the action of the toothed ring, the reel 15 is rotated, thereby releasing the four traction ropes 4 wrapped on its surface. Under the action of gravity, the gravity frame 10 is lowered to cover the grid frame 11.

[0021] A cross slide 12 is provided inside the pump head 2. The X-axis slide of the cross slide 12 is fixedly connected to the top surface inside the pump head 2. The Y-axis slide of the cross slide 12 is movably connected to the slider portion of the X-axis slide, and the slider portion of the Y-axis slide is used to install a tap 13. A downwardly extending electric telescopic rod 19 is fixedly installed on the surface of the X-axis slide slider of the cross slide 12. The telescopic end of the electric telescopic rod 19 is fixedly connected to the surface of the Y-axis slide. The X-axis slide of the cross slide 12 is arranged along the length direction of the pump head 2, and the Y-axis slide of the cross slide 12 is arranged along the width direction of the pump head 2. The two ends of the Y-axis slide of the slide table 12 are slidably connected to the inner wall of the grid frame 11. In actual use, the X-axis slide table drives the electric telescopic rod 19 and the Y-axis slide table to move along the length of the pump head 2. During the movement, the tap 13 moves synchronously along the length of the pump head 2. During the movement along the length, the Y-axis slide table drives the tap 13 to move along the width of the pump head 2. During the movement of the tap 13, the electric telescopic rod 19 is used to extend and retract to realize the Y-axis slide table driving the tap 13 to rise and fall. Fish feces can be extracted layer by layer from top to bottom according to the thickness of the fish feces.

[0022] A piston cylinder 17 is fixedly installed on the inner wall of the pump pipe 1, and a piston ring 18 is slidably installed inside the piston cylinder 17. A flexible hose 14 is provided between the inner edge of the bottom end of the piston ring 18 and the tap 13. Several spring rods 20 are fixedly installed on the bottom end of the inner wall of the piston cylinder 17. The spring rods 20 are parallel to the central axis of the piston cylinder 17, and the telescopic ends of the spring rods 20 are fixedly connected to the outer side of the bottom end of the piston ring 18. As the tap 13 moves away from the piston cylinder 17, the tap 13 drives the flexible hose 14 to pull the piston ring 18 down inside the piston cylinder 17, overcoming the thrust of the spring rods 20. As the tap 13 moves closer to the piston cylinder 17, the piston ring 18 rises inside the piston cylinder 17 under the elastic extension and reset action of the spring rods 20. This allows the piston ring 18 to drive the flexible hose 14 to rise, ensuring that the flexible hose 14 inside the pump head 2 is always in a taut state.

[0023] One pair of outer edges of the pump head 2 are each fitted with a plate 7. Electric rollers 8 are installed on both sides of the bottom edge of the plate 7. The other pair of outer edges of the pump head 2 are each fixedly fitted with an electric push rod 9. The telescopic end of the electric push rod 9 faces downward and is fixedly fitted with a connecting frame 6 connected to the two plates 7. A connecting arm 5 is fixedly fitted on the top edge of the plate 7. The connecting arm 5 is inverted U-shaped and one end of the connecting arm 5 passes through the surface of the pump head 2 and is fixedly connected to the top edge of the grid frame 11. During the movement of the pump head 2 at the bottom of the pool, the electric push rod 9 extends according to the thickness of the fish feces, so that the connecting frame 6 drives the plate 7 to descend. Under the connecting action of the connecting arm 5, the grid frame 11 descends synchronously, so that the electric rollers 8 at the bottom of the plate 7 come into contact with the bottom of the pool. Thus, the water inlet of the pump head 2 is a certain distance from the bottom of the pool and will not come into contact with the fish feces at the bottom of the pool during the movement.

[0024] The method of using this utility model is as follows: The vacuum pump and pump head 2 are delivered to the designated area of ​​the aquaculture pond by a ship. The pump head 2 sinks to near the bottom of the pond. According to the thickness of fish feces at the bottom of the pond, the electric push rod 9 extends, and the insert plate 7 is lowered through the connecting frame 6. The electric roller 8 at the bottom of the insert plate 7 contacts the bottom of the pond. At the same time, the insert plate 7 drives the grid frame 11 to descend synchronously through the inverted U-shaped connecting arm 5, so that the water inlet of the pump head 2 is lifted away from the fish feces layer at the bottom of the pond and does not come into contact with the fish feces, thus avoiding scraping or disturbing the fish feces during movement. The vacuum pump is then started, and the cross slide 12 drives... The movable tap 13 moves in three dimensions: the X-axis slide moves the tap 13 along the length of the pump head 2, the Y-axis slide moves the tap 13 along the width, and the electric telescopic rod 19 controls the raising and lowering of the tap 13 to achieve "top-to-bottom layer-by-layer extraction" of fish feces, ensuring thorough cleaning. To prevent the suction from attracting sea bass, the waterproof motor drives the spur gear 16 to rotate, and through the gear ring, drives the winding reel 15 to release the traction rope 4. The gravity frame 10 descends under its own gravity, covering the grid frame 11 around, forming double protection.

[0025] The wiring diagrams for the motor, electric roller 8, electric push rod 9, and electric telescopic rod 19 in this utility model belong to this invention. The working principle of the motor, electric roller 8, electric push rod 9, and electric telescopic rod 19 are common knowledge in the field. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the motor, electric roller 8, electric push rod 9, and electric telescopic rod 19 will not be explained in detail.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
