Description

Technical Field

[0001] The present invention relates to the field of machinery, and in particular to a feed delivery device. Background Art

[0002] Aquaculture engineering vessels are ships equipped with aquaculture water tanks. The ships can move the aquaculture water tanks to an environment suitable for the growth of aquatic products, which is beneficial to the growth of aquatic products. For example, in winter, the ship can sail to low-latitude tropical waters, and in summer, it can sail to high-latitude waters, so that aquatic products are always in an environment suitable for growth, which is beneficial to increasing production. In addition, deep-sea water can be used for aquaculture, and better water quality can be used for aquaculture, avoiding the use of polluted water quality along the coast.

[0003] When feeding the fish, the feed usually floats on the water surface at the beginning, which is conducive to the fish's eating. However, after a long time, the feed will sink to the bottom of the water tank, which is not conducive to the fish's eating. In addition, the bottom of the water tank usually has a lot of fish feces and bacteria, which can easily make the fish sick.

[0004] Therefore a feed delivery device is needed. Summary of the Invention

[0050] Compared with the prior art, the present invention has the following advantages:

[0051] 1. This application involves a worker first activating a lifting mechanism. The lifting mechanism's actuator drives a connecting rod to move, causing the first flexible body to stretch upward, forming a funnel-shaped opening with a downward opening. The worker then adds fish food to the aquaculture box through the feeding port. If the fish food remains in the aquaculture box for too long, it sinks and enters a groove in the aquaculture box along the inclined first flexible body. The worker then activates a circulation mechanism, the input end of which is fixedly connected to a circulation hole in the outer wall of the aquaculture box. The circulation mechanism sucks out the sinking fish food and re-feeds it to the top of the aquaculture box until the fish in the aquaculture box have consumed all the food. The lifting mechanism then drives the connecting rod down, causing the first flexible body to stretch downward, forming a funnel-shaped opening with a downward opening, so that the sewage pipe is located within the sewage hole of the aquaculture box. At this time, fish feces enter the sewage pipe through the gap between the connecting ribs of the connecting rod and the sewage pipe, and are then discharged out of the aquaculture box through the sewage hole. The technical problem to be solved is how to achieve the reuse of fish food.

[0052] 2. This application involves staff activating two linear actuators. The actuators' actuators are fixedly connected to a support plate, and both ends of the support plate are fixedly connected to corresponding second sliders. As the linear actuators move, the support plates move along the length of the first slide rail. A second perforation is formed in the center of the support plate, and the end of a connecting rod, away from the breeding box, is fixed in the second perforation. This allows the connecting rod to move the first flexible body, thereby changing its shape. The technical problem to be solved is how to control the raising and lowering of the connecting rod.

[0053] 3. This application involves a worker activating a sewage pump, allowing the sinking fish food to enter the sewage pump through a first connecting pipe. The sewage pump's output end is fixedly connected to a second connecting pipe, and the fish food then flows through the second connecting pipe and returns to the aquaculture tank through the water inlet at the top of the aquaculture tank, thereby reusing the sinking fish food. The technical problem to be solved is how to re-introduce the sinking fish food into the aquaculture tank.

[0054] 4. In this application, a staff member activates a sewage pump, which is connected to the circulation hole of the aquaculture tank via a first connecting pipe. With the suction of the sewage pump, water and sinking fish food enter the first connecting pipe through the space between the partition and the aquaculture tank. Because the baffle partition is set vertically and inclined at the center of the corresponding third slider, the third slider is slidably connected to the annular slide formed in the bottom of the groove. As water and fish food pass through the space formed by the baffle and the inner wall of the aquaculture tank, the entire baffle is driven to rotate, thereby rotating the fish food on other baffles to the circulation hole, where it is sucked out by the sewage pump for reuse. The technical problem to be solved is how to completely recover the fish food that has fallen into the groove.

[0055] 5. This application also installs baffles between each pair of partitions. Multiple baffles are provided, with the bottoms of the baffles contacting the bottom inner wall of the groove. The baffles seal the chute, preventing fish food from entering the chute and affecting the rotation of the baffles. The technical problem to be solved is how to prevent fish food from entering the annular chute and affecting the sliding of the baffles.

[0056] 6. This application utilizes an inclined arrangement of partitions. Each partition has multiple guide grooves formed on one end near the inner wall of the aquaculture tank. A space for one-way water flow is formed between the guide grooves and the inner wall of the aquaculture tank. When the sewage pump is activated, the first connecting pipe is fixedly connected to the circulation hole. The suction force of the sewage pump moves water and fish food along the space between the guide grooves and the aquaculture tank, causing the water to move in a fixed direction, thereby driving the partitions to rotate. The technical problem to be solved is to cause the water in the grooves to move in the same direction when the sewage pump is activated.

[0057] 7. This application also installs a cover plate on top of the partition. The cover plate is in the shape of a ring and is fixedly installed at the top of the groove. The outer peripheral surface of the cover plate contacts the inner wall of the breeding box. The cover plate is formed with multiple water holes equidistantly along the circumference. The cover plate restricts the flow direction of the water body so that the water body can only move along the space between the partition plate and the breeding box. Because the partition plate is in a vertical state and is set at an inclined angle, as the water body is sucked by the sewage pump, it can better drive the partition plate to rotate. The technical problem to be solved is how to make the partition plate rotate more smoothly.

[0058] 8. The present application further comprises a second flexible body provided below the first flexible body, wherein the center of the first flexible body is fixedly connected to the outer circumferential surface of the first annular slider, the second flexible body has the same shape as the first flexible body, the edge of the second flexible body is fixedly connected to the center of the corresponding fourth slider, the center of the second flexible body is fixedly connected to the outer circumferential surface of the second annular slider, a first guide hole is formed on one side of the first annular slider along the length direction of the connecting rod, and a first threaded hole is formed on the side of the first annular slider away from the first guide hole; a second guide hole is symmetrically formed on one side of the second annular slider along the length direction of the connecting rod, and a second threaded hole is formed on the side of the second annular slider away from the second guide hole; The first screw rod is vertically arranged in the first guide hole and the second threaded hole; the second screw rod has the same shape as the first screw rod, and is vertically arranged in the first threaded hole and the second guide hole; third holes are symmetrically formed at both ends of the second through-hole of the support plate, and the end of the first screw rod away from the breeding box is arranged in the third through-hole on one side of the support plate, and the end of the second screw rod away from the breeding box is arranged in the third through-hole on the support plate away from the first screw rod; there are two first rotary drives, and the two first rotary drives are fixedly arranged in a vertical state on the side of the support plate away from the breeding box, and the actuators of the two first rotary drives are respectively fixedly connected to the ends of the first screw rod and the second screw rod away from the breeding box. When the first flexible body is damaged, the second flexible body set below the first flexible body can be replenished in time to avoid affecting the breeding process. Then the staff starts the first rotary drive to drive the second screw to rotate. The second screw is vertically set in the first threaded hole and the second guide hole, driving the first annular slider to move and remove the first flexible body from the breeding box. Then, another first rotary drive drives the first screw to rotate and move the second flexible body to the original position of the first flexible body, making it easier for the staff to handle the first flexible body in time. The technical problem to be solved is how to replace the first flexible body in time when it is damaged.

[0059] 9. This application also installs a first limiting ring at the bottom of the groove on the inner wall of the breeding box. The first limiting ring is circular, with its inner circumference close to the side of the groove closest to the inside of the breeding box. When the first and second flexible bodies move downward under the drive of the linear actuator, the second slider contacts the first limiting ring, limiting the displacement of the second flexible body, thereby preventing the first and second flexible bodies from disengaging from the chute when moving downward. The technical problem to be solved is how to prevent the first and second flexible bodies from disengaging from the chute when moving downward.

[0060] 10. The present application provides a second limiting ring at one end of the top of the groove near the chute. When the first flexible body and the second flexible body move upward, the first slider contacts the second limiting ring to prevent the first flexible body and the second flexible body from sliding out of the chute. When the first flexible body needs to be replaced, the staff activates the second rotary drive, which drives the third screw to rotate. The second limiting ring is formed with two third threaded holes, which are threadedly connected to the corresponding third screw, so that the second limiting ring can move away from the chute, so that there is a certain distance between the second limiting ring and the chute. Then, the staff activates the first rotary drive to drive the second screw to rotate, which drives the first annular slider to move. When the annular slider moves upward, the first slider is driven to slide out of the chute. Afterwards, the first annular slider drives the first flexible body and the first slider to move along the first perforation on the top of the breeding box to the outside of the breeding box, thereby replacing the first flexible body. The technical problem to be solved is how to replace the first flexible body. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0087] In order to solve the technical problem of how to realize the reuse of fish food, such as Figure 1-7 As shown, this application provides:

[0089] The lifting mechanism 2 is fixedly arranged at the top center of the breeding box 1;

[0090] A first through-hole 1c is formed at the center of the top of the breeding box 1. A connecting rod 3 is vertically arranged at the center of the interior of the breeding box 1.

[0119] There are multiple partitions 10b, which are vertically arranged at the center of the corresponding third slider 10a. One end of the partition 10b abuts against the inner wall of the groove 1d and is away from the end of the breeding box 1.

[0120] Specifically, in this application, the staff starts the sewage pump 9a, and the sewage pump 9a is connected to the circulation hole 1e of the breeding box 1 through the first connecting pipe 9b. With the suction of the sewage pump 9a, water and sinking fish food enter the first connecting pipe 9b through the space between the partition 10b and the breeding box 1. Since the baffle 10c and the partition 10b are arranged in a vertical state and are arranged at an inclined angle at the center of the corresponding third slider 10a, the third slider 10a is slidably connected to the annular slide groove 1d2 formed at the bottom of the groove 1d. As the water and fish food pass through the space formed by the partition 10b and the inner wall of the breeding box 1, the entire partition 10b is driven to rotate, thereby rotating the fish food on other baffles 10c to the circulation hole 1e, and being sucked out by the sewage pump 9a for reuse.

[0121] Further:

[0122] In order to solve the technical problem of how to prevent fish food from entering the annular chute 1d2 and affecting the sliding of the baffle 10c, as shown in Figures 10-11, the present application provides:

[0123] A baffle 10c is installed between every two partitions 10b. There are multiple baffles 10c, and the bottom of the baffle 10c is in contact with the bottom inner wall of the groove 1d.

[0124] Specifically, the present application further installs a baffle 10c between every two partitions 10b. There are multiple baffles 10c. The bottom of the baffle 10c fits the bottom inner wall of the groove 1d. The baffle 10c seals the chute 1d1 to prevent fish food from entering the chute 1d1 and affecting the rotation of the baffle 10c.

[0125] Further:

[0126] In order to solve the technical problem of moving the water in the groove 1d in the same direction when the sewage pump 9a is started, as shown in FIG. Figure 10-11 As shown, this application provides:

[0127] The partitions 10b are arranged in an inclined state. A plurality of guide grooves 10b1 are formed on one end of each partition 10b close to the inner wall of the breeding box 1. A space for one-way water movement is formed between the guide grooves 10b1 and the inner wall of the breeding box 1.

[0128] Specifically, the present application sets the partitions 10b and 10b in an inclined state, and each partition 10b is formed with multiple guide grooves 10b1 at one end close to the inner wall of the breeding box 1. A space for one-way movement of water supply is formed between the guide groove 10b1 and the inner wall of the breeding box 1. When the sewage pump 9a is started, the first connecting pipe 9b is fixedly connected to the circulation hole 1e. The suction force of the sewage pump 9a will move the water and fish food along the space between the guide groove 10b1 and the breeding box 1, so that the water body moves in a fixed direction, thereby prompting the partition 10b to rotate.

[0129] Further:

[0130] In order to solve the technical problem of how to make the partition 10b rotate more smoothly, as Figure 10-11 As shown, this application provides:

[0131] A cover plate 10d is also installed on the top of the partition 10b. The cover plate 10d is in a circular shape and is fixed on the top of the groove 1d. The outer peripheral surface of the cover plate 10d contacts the inner wall of the breeding box 1. A plurality of water holes 10d1 are formed on the cover plate 10d at equal intervals along the circumferential direction.

[0132] Specifically, the present application also installs a cover plate 10d on the top of the partition 10b. The cover plate 10d is in a circular shape and is fixedly set on the top of the groove 1d. The outer peripheral surface of the cover plate 10d contacts the inner wall of the breeding box 1. A plurality of water holes 10d1 are formed on the cover plate 10d at equal intervals along the circumferential direction. The flow direction of the water body is restricted by the cover plate 10d, so that the water body can only move along the space between the partition plate 10b and the breeding box 1. Since the partition plate 10b is in a vertical state and is set at an inclined angle, as the water body is sucked by the sewage pump 9a, the partition plate 10b is better driven to rotate.

[0133] Further:

[0134] In order to solve the technical problem of how to replace the first flexible body 6 in time when it is damaged, Figure 3 、 Figure 4 、 Figure 8 、 Figure 12 and Figure 13 As shown, this application provides:

[0137] The first annular slider 8b is sleeved on the sewage pipe 4 and is slidably arranged on the two second slide rails 8a.

[0143] Third through-holes 2e2 are symmetrically formed at both ends of the second through-hole 2e1 of the support plate 2e. The end of the first screw rod 8f away from the breeding box 1 is disposed in the third through-hole 2e2 on one side of the support plate 2e. The end of the second screw rod 8g away from the breeding box 1 is disposed in the third through-hole 2e2 of the support plate 2e away from the first screw rod 8f.

[0144] There are two first rotary drivers 8h, and the two first rotary drivers 8h are fixedly arranged in a vertical state on the side of the support plate 2e away from the breeding box 1. The actuators of the two first rotary drivers 8h are respectively fixedly connected to the end of the first screw rod 8f and the second screw rod 8g away from the breeding box 1.

[0145] Specifically, the present application further provides a second flexible body 8e below the first flexible body 6, the center of the first flexible body 6 is fixedly connected to the outer circumference of the first annular slider 8b, the second flexible body 8e has the same shape as the first flexible body 6, the edge of the second flexible body 8e is fixedly connected to the center of the corresponding fourth slider 8d, the center of the second flexible body 8e is fixedly connected to the outer circumference of the second annular slider 8c, the first annular slider 8b is formed with a first guide hole 8b2 on one side along the length direction of the connecting rod 3, and the first annular slider 8b is formed with a first threaded hole 8b1 on the side away from the first guide hole 8b2; the second annular slider 8c is symmetrically formed with a second guide hole 8c2 on one side along the length direction of the connecting rod 3, and the second annular slider 8c is formed with a second threaded hole 8c1 on the side away from the second guide hole 8c2; the first screw rod 8f It is vertically arranged in the first guide hole 8b2 and the second threaded hole 8c1; the second screw rod 8g has the same shape as the first screw rod 8f, and the second screw rod 8g is vertically arranged in the first threaded hole 8b1 and the second guide hole 8c2; the third through-holes 2e2 are symmetrically formed at both ends of the second through-hole 2e1 of the support plate 2e, and the end of the first screw rod 8f away from the breeding box 1 is arranged in the third through-hole 2e2 on one side of the support plate 2e, and the end of the second screw rod 8g away from the breeding box 1 is arranged in the third through-hole 2e2 of the support plate 2e away from the first screw rod 8f; there are two first rotary drivers 8h, and the two first rotary drivers 8h are vertically fixed on one side of the support plate 2e away from the breeding box 1, and the actuators of the two first rotary drivers 8h are respectively fixedly connected to the ends of the first screw rod 8f and the second screw rod 8g away from the breeding box 1. When the first flexible body 6 is damaged, the second flexible body 8e arranged below the first flexible body 6 can be replenished in time to avoid affecting the breeding process. Then the staff starts the first rotary driver 8h to drive the second screw rod 8g to rotate. The second screw rod 8g is vertically arranged in the first threaded hole 8b1 and the second guide hole 8c2, driving the first annular slider 8b to move and move the first flexible body 6 out of the breeding box 1. Then, another first rotary driver 8h drives the first screw rod 8f to rotate and moves the second flexible body 8e to the original position of the first flexible body 6, so that the staff can handle the first flexible body 6 in time.

[0146] Further:

[0147] In order to solve the technical problem of how to prevent the first flexible body 6 and the second flexible body 8e from being separated from the slide groove 1d1 when moving downward, as shown in FIG. Figure 4 、 Figure 11 As shown, this application provides:

[0148] A first limiting ring 1g is also installed at the bottom of the groove 1d on the inner wall of the breeding box 1. The first limiting ring 1g is in a circular ring shape, and the inner circumference of the first limiting ring 1g is close to the side of the groove 1d close to the inside of the breeding box 1.

[0149] Specifically, the present application further installs a first limiting ring 1g at the bottom of the groove 1d on the inner wall of the breeding box 1. The first limiting ring 1g is in the shape of a circular ring, and the inner circumference of the first limiting ring 1g is close to the side of the groove 1d close to the inside of the breeding box 1. When the first flexible body 6 and the second flexible body 8e move downward under the drive of the linear drive 2d, as the second slider 2b contacts the first limiting ring 1g, the displacement of the second flexible body 8e is limited, thereby preventing the first flexible body 6 and the second flexible body 8e from disengaging from the slide groove 1d1 when moving downward.

[0150] Further:

[0151] In order to solve the technical problem of how to replace the first flexible body 6, as Figure 3 、 Figure 5 and Figure 14 As shown, this application provides:

[0152] A limiting mechanism 11 is also provided on the top of the breeding box 1;

[0153] The limiting mechanism 11 includes a second rotation driver 11a, a third screw rod 11b, a second limiting ring 11c and a guide column 11d;

[0154] There are two second rotary drivers 11a, which are fixed vertically at the top edge of the breeding box 1;

[0155] Two fourth through-holes 1h are formed along the circumferential direction at the top edge of the breeding box 1, and there are two third screw rods 11b, which are vertically arranged in the fourth through-holes 1h. There are two third rotary drivers, and the actuators of the two third rotary drivers are fixedly connected to the corresponding third screw rods 11b;

[0156] The second limiting ring 11c is horizontally arranged at the top of the groove 1d near the end of the slide groove 1d1. The second limiting ring 11c is formed with two third threaded holes 11c1 along the circumferential direction. The end of the second screw rod 8g away from the fourth through-hole 1h is threadedly connected to the corresponding third threaded holes 11c1.

[0157] There are two guide posts 11d, which are vertically arranged on the top inner wall of the breeding box 1. The second limiting ring 11c is formed with two third guide holes 11c2 along the circumferential direction. The end of the guide post 11d away from the top of the breeding box 1 is arranged in the corresponding third guide hole 11c2.

[0158] Specifically, the present application is provided with a second limiting ring 11c at one end of the top of the groove 1d near the slide groove 1d1. When the first flexible body 6 and the second flexible body 8e move upward, the first slider 7 contacts the second limiting ring 11c to prevent the first flexible body 6 and the second flexible body 8e from sliding out of the slide groove 1d1. When the first flexible body 6 needs to be replaced, the staff starts the second rotation driver 11a, and the second rotation driver 11a drives the third screw rod 11b to rotate. Two third threaded holes 11c1 are formed on the second limiting ring 11c, and the third threaded holes 11c1 are screwed into the corresponding third screw rod 11b. The groove is connected so that the second limit ring 11c can move away from the slide groove 1d1, so that there is a certain distance between the second limit ring 11c and the slide groove 1d1. Then the staff starts the first rotary driver 8h to drive the second screw rod 8g to rotate, and the second screw rod 8g drives the first annular slider 8b to move. When the annular slider moves upward, the first slider 7 will be driven to slide out of the slide groove 1d1. After that, the first annular slider 8b drives the first flexible body 6 and the first slider 7 along the first through-hole 1c at the top of the breeding box 1 to move out of the breeding box 1, thereby replacing the first flexible body 6.

[0159] In the present application, the staff first starts the lifting mechanism 2, and the executive part of the lifting mechanism 2 drives the connecting rod 3 to move, so that the first flexible body 6 is stretched upward to form a funnel shape with the opening downward. Then the staff adds the fish food into the breeding box 1 through the feeding port 1b. When the fish food is in the breeding box 1 for too long, the fish food will sink. The sunken fish food will enter the groove 1d of the breeding box 1 along the inclined first flexible body 6. Then the staff starts the circulation mechanism 9. The input end of the circulation mechanism 9 is fixedly connected to the circulation hole 1e on the outer wall of the breeding box 1, sucking out the sunken fish food and re-putting the fish food into the breeding box 1. The fish in the culture box 1 eat all the food. Then, the lifting mechanism 2 drives the connecting rod 3 to descend, causing the first flexible body 6 to stretch downward to form a funnel shape with the opening upward, so that the sewage pipe 4 is located in the sewage hole 1a of the culture box 1. At this time, the fish feces will enter the sewage pipe 4 through the gap between the connecting ribs 5 between the connecting rod 3 and the sewage pipe 4, and then be discharged outside the culture box 1 through the sewage hole 1a of the culture box 1. This solves the technical problem of how to reuse fish food. In this application, a worker activates sewage pump 9a, which is connected to the circulation hole 1e of the aquaculture tank 1 via a first connecting pipe 9b. With the suction of sewage pump 9a, water and sinking fish food enter the first connecting pipe 9b through the space between partition 10b and the aquaculture tank 1. Because baffle 10c and baffle 10b are vertically positioned and tilted at the center of the corresponding third slider 10a, the third slider 10a slides into the annular chute 1d2 formed at the bottom of groove 1d. As water and fish food pass through the space formed by baffle 10b and the inner wall of the aquaculture tank 1, the entire baffle 10b rotates, thereby rotating the fish food on the remaining baffle 10c to the circulation hole 1e, where it is sucked out by sewage pump 9a for reuse. This solves the technical problem of how to completely recover fish food that has fallen into groove 1d.The present application further provides a second flexible body 8e below the first flexible body 6, the center of the first flexible body 6 is fixedly connected to the outer circumference of the first annular slider 8b, the second flexible body 8e has the same shape as the first flexible body 6, the edge of the second flexible body 8e is fixedly connected to the center of the corresponding fourth slider 8d, the center of the second flexible body 8e is fixedly connected to the outer circumference of the second annular slider 8c, the first annular slider 8b is formed with a first guide hole 8b2 on one side along the length direction of the connecting rod 3, and the first annular slider 8b is formed with a first threaded hole 8b1 on the side away from the first guide hole 8b2; the second annular slider 8c is symmetrically formed with a second guide hole 8c2 on one side along the length direction of the connecting rod 3, and the second annular slider 8c is formed with a second threaded hole 8c1 on the side away from the second guide hole 8c2; the first screw rod 8f is vertically arranged in the first guide hole 8b2 and the second threaded hole 8c1; the second screw rod 8g has the same shape as the first screw rod 8f, and the second screw rod 8g is vertically arranged in the first threaded hole 8b1 and the second guide hole 8c2; the third through-hole 2e2 is symmetrically formed at both ends of the second through-hole 2e1 of the support plate 2e, and the end of the first screw rod 8f away from the breeding box 1 is arranged in the third through-hole 2e2 on one side of the support plate 2e, and the end of the second screw rod 8g away from the breeding box 1 is arranged in the third through-hole 2e2 of the support plate 2e away from the first screw rod 8f; there are two first rotary drivers 8h, and the two first rotary drivers 8h are vertically fixed on one side of the support plate 2e away from the breeding box 1, and the actuators of the two first rotary drivers 8h are respectively fixedly connected to the ends of the first screw rod 8f and the second screw rod 8g away from the breeding box 1. When the first flexible body 6 is worn out, the second flexible body 8e disposed below the first flexible body 6 can be promptly replenished to avoid affecting the breeding process. Subsequently, the staff activates the first rotary driver 8h, driving the second screw rod 8g to rotate. The second screw rod 8g is vertically disposed within the first threaded hole 8b1 and the second guide hole 8c2, driving the first annular slider 8b to move, removing the first flexible body 6 from the breeding box 1. Subsequently, another first rotary driver 8h drives the first screw rod 8f to rotate, moving the second flexible body 8e to the original position of the first flexible body 6, making it easier for the staff to promptly handle the first flexible body 6. This solves the technical problem of how to promptly replace the first flexible body 6 when it is damaged.
