Description

Technical Field

[0001] This utility model belongs to the field of feeding device technology, and in particular relates to a quantitative feeding device for aquaculture. Background Technology

[0002] Aquaculture is a production activity that utilizes artificial or semi-artificial waters to cultivate aquatic plants and animals through methods such as stocking seedlings, controlling the breeding environment, and feeding. Feeding is a crucial step in ensuring the healthy growth and efficient production of aquatic animals. A reasonable feeding strategy can not only improve feed utilization but also promote the healthy growth of aquatic animals and reduce disease incidence.

[0003] Chinese patent document CN222722255U discloses a quantitative feeding device for aquaculture. It includes a shell, a feed storage tank, a servo motor, a fixing plate, a rotating disk, a fixing shaft, and a flow guide frame. The bottom of the feed storage tank is tightly fitted to the top of the rotating disk. A quantitative trough is formed on the top of the rotating disk, and a fixing plate is installed at the bottom of the rotating disk. A through hole on the fixing plate serves as a discharge port. During quantitative feeding, the rotating disk is rotated. When the quantitative trough on the rotating disk rotates to below the feed storage tank, feed falls into the quantitative trough. The quantitative trough on the rotating disk causes the feed to rotate accordingly. When the quantitative trough rotates to above the discharge port, the feed in the quantitative trough falls through the discharge port. The capacity of the quantitative trough on the rotating disk of this device is fixed, and the rotating disk must be disassembled for replacement. Each time the feeding amount needs to be changed, the device must be disassembled and parts replaced, making the process of adjusting the feeding amount very difficult. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a quantitative feeding device for aquaculture, which makes the quantitative adjustment of feed convenient and quick.

[0005] The aforementioned quantitative feeding device for aquaculture includes a storage hopper with a discharge port at the bottom and a base below it. A quantitative cylinder with its opening facing upwards is positioned between the storage hopper and the base, tilted slightly to the left and lower to the right. The cylinder's opening is located below the discharge port. Sliding grooves are symmetrically arranged on both the front and rear side walls of the quantitative cylinder, and each groove contains a sliding block that slides within it. A locking component is installed on the sliding block to lock it in place after sliding. The base includes a horizontally placed mounting plate, on which a retractable second connecting rod is vertically fixed. The top end of the second connecting rod is bent inwards and rotatably connected to the sliding block. A first limiting platform is fixed, and the right end of the metering cylinder is placed on the first limiting platform. The left end of the metering cylinder can swing downward. A second limiting platform made of magnetic material is fixed on the mounting plate on the left side of the first limiting platform. After the left end of the metering cylinder swings downward, it can be attracted by the magnetic force of the second limiting platform. The discharge port is a square hole. A square locking hole with internal and external communication is opened on the right side wall of the storage tank at the discharge port. A first baffle is placed independently in the locking hole. The left end of the first baffle is located inside the storage tank and is bent upward. The right end of the first baffle passes through the locking hole and is located on the right side of the storage tank. When the left end of the metering cylinder swings downward, the right end of the metering cylinder swings upward and can push the first baffle to the left to close the discharge port.

[0006] When there is feed in the metering cylinder, as the feed gradually increases, the center of gravity of the metering cylinder gradually shifts to the left. When the weight of the feed in the metering cylinder reaches the specified value, the left end of the metering cylinder swings downward. The position of the slider determines the weight of feed required for the metering cylinder to swing downward. After adjusting the slider to the position corresponding to the required feed weight, it is locked. Pulling out the first baffle opens the discharge port, and the feed falls into the metering cylinder. After the specified weight of feed falls into the metering cylinder, due to the change in the center of gravity, the left end of the metering cylinder swings downward about the connection between the slider and the second connecting rod. After the left end of the metering cylinder swings downward, it is attracted by the second limiting platform. At this time, the metering cylinder is in a tilted state with the left side lower and the right side higher. The feed slides out of the metering cylinder opening due to gravity, and the right end of the metering cylinder swings upward, pushing the first baffle to the left to close the discharge port. Compared with the existing technology that requires disassembly of the equipment when changing the feed metering, this aquaculture method only requires adjusting the position of the slider to adjust the feed amount, making the adjustment of the feed metering convenient and quick.

[0007] Furthermore, a counterweight is detachably installed at the right end of the metering cylinder.

[0008] Changing the weight of the counterweight can change the amount of feed required for the left end of the metering cylinder to swing downwards. Increasing the weight of the counterweight will increase the amount of feed required for the left end of the metering cylinder to swing downwards, thus increasing the adjustment range of the metering cylinder's feed dispensing.

[0009] Furthermore, the first baffle is provided with a material leakage hole that is open at both the top and bottom. When the first baffle closes the outlet, the material leakage hole is located in the locking hole on the right side of the outlet. When the outlet is opened, the material leakage hole is located above the opening of the metering cylinder.

[0010] When the first baffle is pulled out to open the discharge port, the leakage hole can carry out the residual feed in the locking hole and let it fall into the metering cylinder.

[0011] Furthermore, a connecting plate is vertically installed at the bottom of the mounting plate. The lower end of the connecting plate is bent to the left and located on the left side of the mounting plate. A throwing disc is rotatably installed on the connecting plate on the left side of the mounting plate. The central part of the throwing disc has a frustum structure. After the left end of the metering cylinder swings downward, the opening of the metering cylinder is located above the throwing disc.

[0012] The feed falls from above the center of the feeding disc and is thrown out by the centrifugal force generated by the rotation, achieving uniform feeding.

[0013] Furthermore, a funnel-shaped guide hopper is fixed to the left end of the mounting plate. After the left end of the metering cylinder swings downward, the opening of the metering cylinder is located above the guide hopper, and the lower end of the guide hopper is located above the throwing plate.

[0014] The feed poured from the metering cylinder is collected, making the feed that falls onto the throwing plate more accurately positioned and improving the dispersion effect of the feed on the central truncated cone of the throwing plate.

[0015] Furthermore, a second baffle is vertically fixed to the bottom of the mounting plate. The second baffle is located on the right side of the throwing disc, and the left side of the second baffle has an arc-shaped structure and is in clearance fit with the throwing disc.

[0016] When the device is placed on the bank, the second baffle limits the angle at which the feed is thrown from the throwing plate, preventing the feed from being thrown towards the bank and directing it towards the center of the feeding pond.

[0017] Furthermore, the upper inner wall of the locking hole is inclined to the left and lower to the right, while the lower inner wall of the locking hole is horizontal.

[0018] Close the discharge port after ensuring that the first baffle can be pushed in by the metering cylinder.

[0019] Furthermore, the throwing disc has multiple stops evenly distributed along its circumference in an inward and outward direction.

[0020] During the rotation of the feeding disc, the feed is pushed by the baffles, which makes the feed rotate faster on the feeding disc, increases the throwing distance, and makes the feed more evenly distributed.

[0021] Furthermore, the throwing disc has several through holes that are connected vertically.

[0022] After the feed falls onto the feeding plate, a small portion of the feed leaks down to the area below the through hole.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] Compared with existing technologies that require disassembly of equipment to change the feed quantity, this quantitative feeding device for aquaculture only requires adjusting the position of the slider in the chute to adjust the feed quantity, making the adjustment of the feed quantity convenient and quick.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Example

[0033] The quantitative feeding device for aquaculture is implemented using the following scheme:

[0034] like Figure 1 and Figure 2As shown, a long, rectangular mounting plate 7.3 is to be placed horizontally. A second limiting platform 7.2 and a first limiting platform 7.1 are fixedly installed at intervals on the top left and right sides of the plate. The first limiting platform 7.1 is higher than the second limiting platform 7.2, and the top of the second limiting platform 7.2 is made of magnetic material. An "L"-shaped connecting plate 7.4 is fixedly installed at the bottom of the mounting plate 7.3. The upper end of the connecting plate 7.4 is fixed to the mounting plate 7.3, and the lower end is bent to the left and located on the left side of the mounting plate 7.3. A motor is vertically installed on the left end of the connecting plate 7.4. A throwing disc 9 is fixedly installed vertically upwards on the motor shaft. The top center of the throwing disc 9 has a frustum structure, and the motor drives the throwing disc 9 to rotate. Multiple stops are evenly distributed along the circumference of the throwing disc 9 in an inward and outward direction. Several through holes are opened on the throwing disc 9, which are interconnected vertically. A second baffle 8 with an arc-shaped structure is vertically fixed to the bottom of the mounting plate 7.3. The second baffle 8 is located on the right side of the throwing disc 9, and the left side wall of the second baffle 8 is in clearance fit with the throwing disc 9. A funnel-shaped guide hopper 10 is fixedly installed at the left end of the mounting plate 7.3. The guide hopper 10 is above the throwing disc 9 and coincides with the axis of the throwing disc 9.

[0035] like Figure 1 and Figure 2 As shown, a first connecting rod 11 and a second connecting rod 12, which are vertically upward and symmetrically arranged front and back, are fixedly installed on the top of the mounting plate 7.3. The first connecting rod 11 consists of two straight rods, and the second connecting rod 12 is a telescopic rod with a bearing fixedly installed after its top end is bent inward. A storage hopper 2 is fixedly installed on the top of the first connecting rod 11, and a metering cylinder 5 is provided on the inner side of the second connecting rod 12.

[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the metering cylinder 5 is a cylinder with an oblique opening at the left end and a sealed right end. "T"-shaped grooves are formed on both the front and rear side walls of the metering cylinder 5, arranged symmetrically. Each groove contains a sliding block 13 that slides along its axis. The metering cylinder 5 has graduations on one side of each groove. A locking assembly, including a bolt, is installed on the sliding block 13. The bolt threadedly engages with the sliding block 13. Tightening the bolt locks the sliding block 13 in place by friction between the bolt's threaded end and the groove bottom. The sliding block 13 is rotatably connected to a bearing on the inner end of the second connecting rod 12. The metering cylinder 5 is made of a magnetic alloy and can be magnetically attracted by the top of the second limiting platform 7.2. The metering cylinder 5 can swing between the first limiting platform 7.1 and the second limiting platform 7.2. When the right end of the metering cylinder 5 swings downward and comes into contact with the first limiting platform 7.1, the cylinder opening is below the discharge port 3. When the left end of the metering cylinder 5 swings downward and is attracted by the second limiting platform 7.2, the cylinder opening is above the guide hopper 10. A counterweight 6 is detachably installed on the right end of the metering cylinder 5.

[0037] like Figure 1 and Figure 2 As shown, the storage bin 2 has a feed inlet 1 and a top cover for closing the feed inlet 1 at the top, and a discharge outlet 3 at the bottom. The discharge outlet 3 is a square hole. The storage bin 2 has a square locking hole 15 on the right side wall at the discharge outlet 3, which is open to both the inside and outside. The upper inner wall of the locking hole 15 is inclined from left to right, and the lower inner wall is horizontal. The discharge outlet 3 is smaller than the opening of the metering cylinder 5, and a first baffle 4 is placed in the locking hole 15.

[0038] like Figure 1 , Figure 4 and Figure 6 As shown, the left end of the first baffle 4 is located inside the storage bin 2 and is bent upwards. The right end of the first baffle 4 passes through the locking hole 15 and is located on the right side of the storage bin 2. When the left end of the metering cylinder 5 swings downwards, the right end of the metering cylinder 5 swings upwards, and can push the first baffle 4 to the left to close the discharge port 3. The first baffle 4 has a vertically connected leakage hole 14. When the first baffle 4 closes the discharge port 3, the leakage hole 14 is located in the locking hole 15 on the right side of the discharge port 3. When the discharge port 3 is opened, the leakage hole 14 is located above the opening of the metering cylinder 5. The leakage hole 14 can bring out the feed remaining in the locking hole 15 and fall into the metering cylinder 5 when the first baffle 4 is pulled out to open the discharge port 3.

[0039] The specific instructions for using the above technical solution are as follows:

[0040] After pushing the first baffle 4 into the discharge port 3 to close the discharge port 3, feed is poured in from the inlet 1. Based on the weight of the counterweight 6 and the different positions of the slider 13 on the scale line of the metering cylinder 5, representing the amount of feed required for the left end of the metering cylinder 5 to swing downward, the bottom of the metering cylinder 5 is placed on the first limiting platform 7.1, and the bolt on the slider 13 is rotated to lock the slider 13. At this time, the opening of the metering cylinder 5 is facing upward and located below the discharge port 3.

[0041] Pull out the first baffle 4, and the feed falls from the outlet 3 into the metering cylinder 5. The leakage hole 14 pulls out any remaining feed from the locking hole 15 and into the metering cylinder 5. As the feed in the metering cylinder 5 increases to the specified amount, the center of gravity of the metering cylinder 5 shifts to the left, and the left end of the metering cylinder 5 swings downward. During the swinging process, the right end of the metering cylinder 5 pushes the first baffle 4 to the left, closing the outlet 3 and stopping the discharge. The left end of the metering cylinder 5 swings downward until it is attracted by the second limiting platform 7.2. At this time, the metering cylinder 5 is in an inclined state with the left side lower and the right side higher, and the feed is poured into the guide hopper 10 under the action of gravity. The guide hopper 10 collects the feed and it falls into the center of the throwing plate 9. The truncated cone at the center of the throwing plate 9 disperses the feed to the perimeter of the throwing plate 9. A small portion of the feed leaks out from the through hole on the throwing plate 9, and the rest of the feed is thrown out by the centrifugal force generated by the rotation of the baffle, achieving uniform feeding. The second baffle 8 can limit the feeding angle so that the feed can only be thrown forward.

[0042] The effects of the above solution:

[0043] This type of quantitative feeding device for aquaculture relies on the left and right sliding of the slider 13 and the easily replaceable counterweight 6 to adjust the amount of feed, making the quantitative adjustment of feed convenient and quick.

[0044] The quantitative feeding device for aquaculture is mainly achieved by the oscillation of the metering cylinder 5 due to the change in its center of gravity. The oscillation of the metering cylinder 5 simultaneously realizes the quantitative feeding and delivery, increasing efficiency, reducing the complexity of the equipment, and saving energy while using a purely mechanical structure with high reliability. At the same time, the oscillation of the metering cylinder 5 facilitates the cleaning of the equipment; workers only need to rotate the metering cylinder 5 to a suitable position to easily clean the inside.

[0045] The feeding tray 9 can evenly distribute the feed in all directions, effectively preventing the accumulation of uneaten feed and feces, which can lead to local water quality deterioration, fish diseases, and competition for food. Smaller or weaker fish may not be able to obtain enough food or may be injured during the competition for food, affecting the fish's immunity and growth performance.
