Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a quantitative feeding device for shrimp farming. Background Technology

[0002] With the continuous improvement of aquaculture technology, the scale and scope of aquaculture are constantly developing and expanding. Shrimp farming, as a major industry, is also seeing continuous technological advancements. Shrimp farming requires precise control of feed quantity, as the feeding process is a key factor affecting shrimp growth rate, survival rate, and farming efficiency. Traditional shrimp farming often uses manual feeding, where farmers estimate the amount of feed based on experience and then manually scatter the feed into the pond. This manual estimation has low accuracy, easily leading to overfeeding resulting in feed waste and water pollution, or underfeeding affecting shrimp growth. Therefore, to solve these problems, improve the efficiency and quality of shrimp farming, and reduce losses, this utility model has emerged. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] A quantitative feeding device for shrimp farming includes a base, a support structure fixedly connected to the top of the base, a storage hopper and a discharge structure fixedly connected to the outer wall of the support structure, and the discharge structure being located below the storage hopper.

[0005] The discharge structure includes a drive motor, the output shaft of which is fixedly connected to a connecting rod, the bottom of which is fixedly connected to a discharge block, the top of which is evenly provided with several discharge holes, and the bottom of which is fixedly connected to a feeding structure.

[0006] Preferably, the support structure includes a support frame, a rotating column is provided at the bottom of the support frame, an mounting cylinder is provided on the base, the lower end of the rotating column passes through the mounting cylinder and the end is rotatably mounted on the base, and a drive structure capable of driving the rotating column to rotate is provided on the mounting cylinder.

[0007] Preferably, the driving structure includes:

[0008] A worm gear is coaxially fixed on a rotating column, and the worm gear is located inside a mounting cylinder;

[0009] A worm gear is horizontally rotatably mounted on a mounting cylinder. The worm gear is connected to a worm wheel via a transmission. One end of the worm gear extends out of the mounting cylinder and a rotating handle is fixed to the end of the worm gear.

[0010] Preferably, the outer wall of the support frame is fixedly connected with a diagonal brace, and the end of the support frame away from the base is fixedly connected with a first support block and a second support block.

[0011] Preferably, the bottom of the first support block is fixedly connected to the top of the drive motor, and a connecting rod is rotatably connected to the outer wall of the second support block.

[0013] Preferably, a second feeding tube is slidably connected to the inner wall of the first feeding tube, and the first feeding tube and the second feeding tube are fixedly connected by fastening bolts.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a discharge structure, has four discharge holes evenly opened on the top of the discharge block that rotate with the connecting rod driven by the drive motor. By controlling the number of rotations of the discharge block, the feed in the storage hopper can be quantitatively transported to the feeding structure. Compared with the traditional method of manually estimating the amount of feed based on experience, this effectively avoids the problems of feed waste and water pollution caused by overfeeding, as well as the problem of underfeeding affecting shrimp growth, thereby improving the resource utilization rate and ecological benefits of shrimp farming.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Please see Figure 1 -2, a quantitative feeding device for shrimp farming, comprising: a base 1, a support structure 2 fixedly connected to the top of the base 1, a storage hopper 3 fixedly connected to the outer wall of the support structure 2, and a discharge structure 4 disposed below the storage hopper 3.

[0025] The discharge structure 4 includes a drive motor 41, the output shaft of the drive motor 41 is fixedly connected to a connecting rod 42, the bottom of the connecting rod 42 is fixedly connected to a discharge block 43, a drop pipe is connected below the storage hopper 3, the lower end of the drop pipe is close to the upper side of the discharge block 43, and a number of discharge holes 44 are evenly opened on the top of the discharge block 43. Preferably, there are four discharge holes 44. When the discharge block 43 rotates one revolution, all four discharge holes 44 pass directly below the drop pipe.

[0026] The bottom of the discharge block 43 is fixedly connected to the feeding structure 45. When the drive motor 41 is started, its output shaft drives the connecting rod 42 to rotate. The second support block 24 provides rotational support for the connecting rod 42. The discharge block 43 at the bottom of the connecting rod 42 rotates synchronously with it. When the discharge hole 44 rotates to the storage hopper 3, the feed in the storage hopper 3 falls into the discharge hole 44 at the top of the discharge block 43 under the action of gravity. When the discharge hole 44 rotates to the bottom, the feed falls from the drop pipe into the discharge hole 44 and then enters the feeding structure 45. The quantitative conveying of feed is achieved by controlling the number of rotations of the discharge block 43.

[0027] The gap between the lower end of the drop tube and the upper side of the discharge block 43 is small, but it does not affect the normal rotation of the discharge block 43. When the discharge hole 44 is misaligned with the lower end of the drop tube, the feed is blocked in the storage hopper 3 and will not fall. When the discharge hole 44 rotates to the lower part of the drop tube, the feed can fall into the discharge hole 44. The rotation speed of the drive motor is relatively slow, which can ensure that the feed in the storage hopper 3 falls into the discharge hole 44 in a timely and quantitative manner.

[0028] Preferably, the output shaft of the drive motor 41 is provided with a gearbox, and the connecting rod 42 is connected to the output shaft of the drive motor 41 through the gearbox. The gearbox controls the rotation speed of the discharge block 43.

[0029] Please see Figure 3-4 The support structure 2 includes a support frame 21, a rotating column 25 at the bottom of the support frame 21, an installation cylinder 11 on the base 1, the lower end of the rotating column 25 passing through the installation cylinder 11 and the end rotatably mounted on the base 1, a worm gear 26 coaxially fixed on the rotating column 25 located inside the installation cylinder 11, a worm 12 horizontally rotatably mounted inside the installation cylinder 11, the worm 12 and the worm gear 26 being connected in a transmission, one end of the worm 12 extending out of the installation cylinder 11 and a rotating handle 13 fixed at the end, when feed needs to be replenished, the feed hopper 3 on the support frame 2 can be turned to the shore to replenish feed by operating the rotating handle.

[0030] Preferably, the end of the worm gear 12 extending out of the mounting cylinder 11 is provided with an external thread, and a fixing nut 14 is threaded onto the external thread. When the rotating column 25 needs to be fixed, the fixing nut 14 is rotated to make it fit tightly against the outer wall of the mounting cylinder 11, thereby fixing the worm gear 12 and the worm wheel 26 at the current angle.

[0031] The outer wall of the support frame 21 is fixedly connected with a diagonal brace 22. The end of the support frame 21 away from the base 1 is fixedly connected with a first support block 23 and a second support block 24. The bottom of the first support block 23 is fixedly connected to the top of the drive motor 41. The outer wall of the second support block 24 is rotatably connected with a connecting rod 42. The base 1 is installed at a suitable position on the bank of the aquaculture pond with bolts and nuts to ensure that it is in close contact with the ground. In the support structure 2, the bottom of the support frame 21 is fixed to the top of the base 1. The diagonal brace 22 enhances the stability of the support frame 21 and prevents the device from shaking. The first support block 23 and the second support block 24 provide support for the drive motor 41 and the connecting rod 42 respectively, ensuring the stability when the output shaft of the drive motor 41 drives the connecting rod 42 to rotate, and ensuring stable discharge of the subsequent discharge structure 4.

[0032] Please see Figure 5The feeding structure 45 includes a feeding hopper 452. A fixing rod 451 is symmetrically fixedly connected to the top of the feeding hopper 452. A first feeding tube 453 is fixedly connected to the bottom of the feeding hopper 452. A second feeding tube 454 is slidably connected to the inner wall of the first feeding tube 453. The first feeding tube 453 and the second feeding tube 454 are fixedly connected by a fastening bolt 455. The feed falls from the discharge hole 44 into the feeding hopper 452 of the feeding structure 45. The fixing rod 451 ensures that the feeding hopper 452 is firmly connected to the discharge block 43. If it is necessary to adjust the size of the feeding area, loosen the fastening bolt 455 and push the second feeding tube 454 to slide on the inner wall of the first feeding tube 453 to change the total length of the two. After the adjustment is completed, tighten the fastening bolt 455 to fix it. The feeding range can be flexibly adjusted by rotating the first feeding tube 453 and the second feeding tube 454.

[0033] Working principle:

[0034] When in use, install the base 1 at a suitable position on the bank of the aquaculture pond using bolts and nuts, ensuring that it is in close contact with the ground. The bottom of the support frame 21 is rotatably connected to the base 1 via the rotating column 25. Adjust the angle of the support structure by rotating the handle to rotate it to the bank or above the aquaculture pond.

[0035] The diagonal brace 22 enhances the stability of the support frame 21 and prevents the device from shaking. The first support block 23 and the second support block 24 provide support for the drive motor 41 and the connecting rod 42 respectively, ensuring the stability when the output shaft of the drive motor 41 drives the connecting rod 42 to rotate, and ensuring stable material discharge from the subsequent discharge structure 4.

[0036] When the drive motor 41 is started, its output shaft drives the connecting rod 42 to rotate. The second support block 24 provides rotational support for the connecting rod 42. The discharge block 43 at the bottom of the connecting rod 42 rotates synchronously with it. When the discharge hole 44 rotates to below the drop pipe of the storage hopper 3, the feed in the storage hopper 3 falls into the discharge hole 44 of the discharge block 43 under the action of gravity and enters the feeding structure 45 to realize the quantitative delivery of feed.

[0037] Feed falls from the discharge hole 44 into the feeding hopper 452 of the feeding structure 45. The fixing rod 451 ensures that the feeding hopper 452 is firmly connected to the discharge block 43. If it is necessary to adjust the size of the feeding area, loosen the fastening bolt 455 and push the second feeding tube 454 to slide on the inner wall of the first feeding tube 453 to change the total length of the two. After the adjustment is completed, tighten the fastening bolt 455 to fix it, thereby realizing the flexible adjustment of the feeding range.
