Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture feeding, in particular to a floating automatic feeding device. Background Art

[0002] The proportion of fishery output value accounts for 9.3% of China's agricultural output value. Fishery is an important part of increasing farmers' income and enriching the food menu. As of 2023, the data of the national fishery statistical bulletin shows that the output value of aquaculture products accounts for 80% of the output value of fishery products. However, at present, China has not formed a large-scale industrial aquaculture model on a large scale, and the main mode is still the scattered aquaculture by fishermen. In the mode of scattered aquaculture by fishermen, the distances between the aquaculture ponds of fishermen are relatively far and the areas of each pond are relatively small. When fishermen feed, they need to transport feed over a long distance to the designated pond to achieve feeding. When feeding, due to the small area of the pond and the small number of fish in the pond, when the feeding amount is too large, it is easy to cause too high ammonia nitrogen and pH value in the water body; when the feeding amount is too small, manual feeding needs to be carried out multiple times, which is time-consuming and laborious, and it is easy for fish not to ingest enough feed to ensure the nutrients required for growth, reducing the aquaculture efficiency.

[0003] To improve the feeding efficiency, such as the patent document with Chinese patent application number 202210832961.3 and publication date of August 18, 2023, which discloses an underwater liquid feed feeding machine, including a bottom box; and a feeding box fixedly connected above the bottom box; a feeding assembly is arranged inside the feeding box for feeding the feed; the feeding assembly includes: a first driving member fixedly connected inside the feeding box; a rotating shaft fixedly connected to the output end of the first driving member; a feeding blade is also fixedly connected to the rotating shaft; and a feeding box is arranged outside the feeding blade; a push rod is slidably connected inside the feeding box. By setting a material pounding assembly in the present invention, the device can pound the caked feeding material, further improving the feeding effect of the device. By combining the feeding assembly and the material pounding assembly, the device can perform quantitative feeding and greatly improve the feeding effect of the device.

[0004] The above-mentioned document drives the first and second rotating rods by a servo motor to drive the pressing block to move downward to achieve extrusion and pounding. After pounding, the feed is discharged from the filter plate to ensure quantitative feeding. However, the above structure cannot determine to start fish feed feeding when there is a fish impact nearby, the feeding accuracy is low, and the above structure needs to extrude the feed, so the feeding efficiency is low. Content of the Utility Model

[0005] The purpose of the utility model is to provide a floating feeding device that starts feeding only when there is a fish impact, saving time, labor and cost, and having high stability and good reliability.

[0006] To achieve the above object, the utility model provides a floating feeding device, which includes a floating device and a feeding device. The feeding device is arranged on the floating device. The feeding device includes an outer shell, a top rod and a feed guiding device. The feed guiding device is arranged at the lower end inside the outer shell. The feed guiding device includes a guiding body. Two or more feeding ports are arranged on the four sides of the upper end of the guiding body at uniform intervals on the outer peripheral wall. The lower end of the guiding body is provided with a discharge port corresponding to the feeding port. Two or more blanking channels are arranged on the outer side wall of the guiding body. The blanking channels are respectively communicated with the feeding port and the discharge port. A containing cavity is arranged inside the guiding body. The top rod penetrates through the containing cavity of the guiding body and is arranged inside the outer shell. One end of the top rod is connected with a limiting device, and the other end of the top rod is exposed. Two or more tension elastic members II are arranged inside the containing cavity. The tension elastic members II are connected with a baffle fixedly sleeved on the top rod. The baffle plugs the discharge port, and the tension elastic members II are in a stretched state.

[0007] With the above settings, by arranging the feeding ports at uniform intervals in a circle on the guiding body, the feed entering the storage cavity can uniformly flow into the feeding ports from the four sides of the guiding body, and then fill the blanking channels. By arranging a containing cavity inside the guiding body and arranging tension elastic members II in the containing cavity to be connected with the baffle fixed on the top rod, the gravity of the top rod and the baffle itself can be offset by the tension of the tension elastic members II, so that the tension elastic members II are in a stretched state. In this way, when a fish collides with the top rod, the top rod is subjected to an upward force and can move upward in the containing cavity, thereby driving the baffle to move upward, so that a gap is formed between the baffle abutted in the blanking channel and the inner wall of the outer shell. The feed filled in the blanking channel can flow out from the gap and flow to the water surface through the discharge port to feed the fish. In this process, no additional electric drive is required to achieve feeding, which is time-saving, labor-saving and cost-saving, and can accurately feed when there is a fish hitting the top rod nearby, with high feeding efficiency.

[0008] Further, the feeding device further includes a cover, which is detachably arranged on the top of the outer shell, and a storage cavity is formed between the feed guiding device and the cover inside the outer shell.

[0009] With the above settings, by arranging the cover, the upper end of the discharge cavity can be sealed to prevent the feed from being affected by the outside.

[0010] Further, the outer housing includes a boss, a transition portion, a housing main body, and an inclined portion. The outer side of the boss is provided with a thread that matches the cover, and is screwed to the cover through the thread. The bottom of the boss is fixedly connected to one end of the transition portion, the other end of the transition portion is fixedly connected to one end of the housing main body, and the other end of the housing main body is fixedly connected to the inclined portion. The inclined portion is inclined downward along the axial direction and gradually becomes smaller to match the induction body. The cross-sectional area of the boss is larger than the cross-sectional area of the housing main body, and the cross-sectional area of the housing main body is larger than the cross-sectional area of the transition portion. Two or more pressure relief ports are provided at circumferentially uniform intervals on the outer side wall of the transition portion.

[0011] With the above settings, after the outer housing passes through the through hole, it is convenient for the boss to abut against the mounting plate, so that the transition portion, the housing main body, and the inclined portion are suspended in the bracket. In addition, the induction body can be placed in the inclined portion in a matching manner. By providing the pressure relief port, the air pressure in the storage cavity can be made the same as the external air pressure, so that the feed in the storage cavity can flow into the filling and feeding channel through the feed inlet.

[0012] Further, the floating device includes a bracket and a floating plate. The top of the bracket is fixedly provided with a mounting plate, and a through hole that matches the housing main body is provided on the mounting plate. Two or more mounting seats are provided on both sides of the bottom of the bracket, and floating plates are provided on the mounting seats.

[0013] With the above settings, it is convenient for the feeding device to pass through the through hole and be stably suspended on the bracket. By providing the floating plate, the bracket can float on the water surface.

[0014] Further, the limiting device includes a connecting block and two or more connecting rods. A groove that matches the ejector rod is provided at the bottom of the connecting block. The connecting rods are arranged at circumferentially uniform intervals on the four sides of the connecting block. One end of the connecting rod is ball-jointed to the outer side of the connecting block, and the other end of the connecting rod is ball-jointed to the inner side wall of the transition portion.

[0015] With the above settings, during the upward movement of the ejector rod when it is collided by a fish, the ejector rod can abut against the connecting block and drive the connecting block to move upward, which can buffer and limit the upward movement distance of the ejector rod at the same time.

[0016] Further, a frustum is provided between the limiting device and the induction body. The inside of the frustum is a hollow structure. The upper end of the frustum abuts against the bottom of the connecting block, and the lower end of the frustum is fixedly connected to the induction body.

[0017] With the above settings, it is convenient to isolate the feed in the storage cavity from contacting the ejector rod. At the same time, due to the inclination of the outer side wall of the frustum, it is convenient for the feed to flow to the feed inlet.

[0018] Further, chamfers are provided at circumferentially uniform intervals on the four sides of the induction body where the frustum is located, and the chamfers are connected to the feed inlet.

[0019] With the above settings, the chamfer increases the contact area with the feed, facilitating the better flow of the feed in the storage cavity into the feed inlet.

[0020] Furthermore, the opening size of the feeding channel connected to the feed inlet is larger than that of the feeding channel connected to the discharge outlet. A notch is provided at the connection of the feeding channel and the discharge outlet, and a baffle is blocked in the notch.

[0021] With the above settings, the feed flowing into the feeding channel is gradually filled in the feeding channel under the blockage of the baffle.

[0022] Furthermore, the feed induction device further includes a discharge guide rail. One end of the discharge guide rail is connected to the discharge outlet, and the other end of the discharge guide rail extends outward and downward to the water surface.

[0023] With the above settings, it is convenient for the material to flow to the water surface through the discharge guide rail to achieve feeding.

[0024] Furthermore, a first tension elastic member is provided in the accommodation cavity. The first tension elastic members are evenly spaced in a circumferential manner in a plane perpendicular to the axis of the induction body. One end of the first tension elastic member is fixedly connected to the ejector rod, and the other end of the first tension elastic member is fixedly connected to the side wall of the accommodation cavity; the second tension elastic members located below the first tension elastic members are evenly spaced in a circumferential manner. One end of the second tension elastic member is fixedly connected in the accommodation cavity, and the other end of the second tension elastic member is fixedly connected to the baffle along the axis direction of the induction body.

[0025] With the above settings, by connecting the first tension elastic member to the ejector rod, during the upward movement of the ejector rod when it is collided by a fish, the deflection angle between the ejector rod and the axis is reduced, and then it quickly resets under the action of the spring; by setting the second tension elastic member to be connected to the baffle, the gravity of the ejector rod and the baffle itself can be offset by the tension of the spring, so that when the fish collides with the ejector rod, the ejector rod can move upward.

[0034] The present utility model will be further described in detail below in conjunction with the accompanying drawings and detailed implementation manners.

[0035] As Figures 1-8 shown, a floating automatic feeding device includes a floating device and a feeding device. The feeding device is arranged on the floating device. The feeding device includes a housing body, a cover 21, a top rod 22 and a feed induction device. The cover 21 is arranged on the top of the housing body.

[0036] As Figure 7 shown, in one embodiment, the floating device includes a bracket 11 and a floating plate 13. The top of the bracket 1 is fixedly provided with a mounting plate 11. There is a through hole (not marked in the figure) on the mounting plate 11 that matches the housing body. Four mounting seats 12 are provided on both sides of the bottom of the bracket 1. Each mounting seat 12 is fixedly provided with a floating plate 13. After the feeding device passes through the through hole and is stably placed on the bracket 1, the bracket 1 can float on the water surface through the floating plate 13.

[0037] In another embodiment, it can also be achieved by sleeving a floating plate outside the housing body.

[0038] As Figure 2 and 4 shown, the feed induction device is arranged at the lower end inside the housing body. The housing body includes a boss 23, a transition part 24, a housing main body 25 and an inclined part 26. The outside of the boss 23 is provided with a thread that matches the cover 21 and is screwed with the cover 21 through the thread. There is a handle 27 on the cover 21. The bottom of the boss 23 is fixedly connected to one end of the transition part 24. The other end of the transition part 24 is fixedly connected to one end of the housing main body 25. The other end of the housing main body 25 is fixedly connected to the inclined part 26. The inclined part 26 gradually becomes smaller along the axial direction downward. The cross-sectional area of the boss 23 is larger than the cross-sectional area of the housing main body 25. The cross-sectional area of the housing main body 25 is larger than the cross-sectional area of the transition part 24.

[0039] The feed induction device includes an induction body 28 and a discharge guide rail 29. A storage chamber 20 is formed between the induction body 28 and the cover 21. The outer side wall of the transition part 24 is provided with more than two pressure relief ports 241 arranged at uniform intervals in a circumferential manner, so that the air pressure in the storage chamber 20 is the same as the external air pressure. A limiting device is arranged in the storage chamber 20.

[0040] As Figure 6 shown, the limiting device includes a connecting block 3 and more than two connecting rods 4. In this embodiment, the number of connecting rods 4 is set to eight. The bottom of the connecting block 3 is provided with a groove matching the ejector rod 22. The eight connecting rods 4 are arranged at uniform intervals in a circumferential manner on the four sides of the connecting block 3 in a plane perpendicular to the axis where the transition part 24 is located. One end of the connecting rod 4 is ball-jointed with a ball hinge seat 30 arranged on the outer side of the connecting block 3, and the other end of the connecting rod 4 is ball-jointed with the inner side wall of the transition part 24. In this way, during the process that the ejector rod 22 moves upward when collided by a fish, the ejector rod 22 can abut against the connecting block 3 and drive the connecting block 3 to move upward, so as to limit the upward moving distance of the ejector rod 22 while playing a buffering role.

[0041] As Figure 4 and 5 shown, a frustum 5 is arranged between the limiting device and the induction body. The inside of the frustum 5 is a hollow structure. The upper end of the frustum 5 abuts against the bottom of the connecting block 3, and the lower end of the frustum 5 is fixedly connected with the induction body 28, which is convenient for isolating the feed in the storage chamber 20 from direct contact with the ejector rod 22. The upper end of the induction body 28 is provided with more than two feed inlets 6 arranged at uniform intervals in a circumferential manner. In this embodiment, the number of feed inlets 6 is set to eight. Chamfers 7 corresponding to the feed inlets 6 are arranged on the four sides of the induction body 28 where the frustum 5 is located. The chamfers 7 are connected with the feed inlets 6, and the contact area with the feed is increased through the chamfers 7, which is convenient for the feed in the storage chamber 20 to flow into the feed inlets 6 better. The lower end of the induction body 28 is provided with a discharge port 8 corresponding to the feed inlet 6. The upper end of the induction body 28 gradually becomes smaller along the axial direction towards the lower end. The outer side wall of the induction body 28 is provided with a blanking channel 9 communicating with the feed inlet 6 and the discharge port 8 respectively. The opening size of the blanking channel 9 connected with the feed inlet 6 is larger than the opening size of the blanking channel 9 connected with the discharge port 8. A notch 31 is arranged at the connection of the blanking channel 9 and the discharge port 8. The edge of the baffle 32 protrudes and is arranged in the notch 31, so that the feed flowing into the blanking channel 9 is gradually filled with the blanking channel 9 under the blockage of the baffle 32. One end of the discharge guide rail 29 is connected with the discharge port 8, and the other end of the discharge guide rail 29 extends outward and downward to the water surface, which is convenient for the blanking to flow to the water surface through the discharge guide rail 29. In this embodiment, the inner side wall of the inclined part of the outer housing is arranged to be in fit with the outer side wall of the induction body 28, and the blanking channel 9 on the induction body 28 and the inclined part form a blanking pipeline, and the bottom of the frustum 5 covers the upper end of the induction body 28.

[0042] AsFigure 4 and 5 As shown in 5 , a receiving cavity 33 is provided in the inducer 28. Inside the receiving cavity 33, there are more than two tension elastic members one 41 connected to the ejector rod 22 and a tension elastic member two 42 connected to a baffle 32 fixedly sleeved on the ejector rod 22. In this embodiment, the tension elastic members one 41 are evenly spaced in a circumferential manner in a plane perpendicular to the axis of the inducer 28. One end of the tension elastic member one 41 is fixedly connected to the ejector rod 22, and the other end of the tension elastic member one 41 is fixedly connected to the side wall of the receiving cavity 33. By connecting the tension elastic member one 41 to the ejector rod 22, during the process of the ejector rod 22 moving upward due to being collided by a fish, the yaw angle between the ejector rod 22 and the axis is reduced, and then it quickly resets under the action of the tension elastic member one 41; the tension elastic members two 42 located below the tension elastic members one 41 are evenly spaced in a circumferential manner. One end of the tension elastic member two 42 is fixedly connected inside the receiving cavity 33, and the other end of the tension elastic member two 42 is fixedly connected to the baffle 32 along the axis direction of the inducer 28. By setting the tension elastic member two 42 to be connected to the baffle 32, the gravity of the ejector rod 22 and the baffle 32 itself can be offset by the tension of the tension elastic member two 42. The tension elastic member two 42 is in a stretched state, so that when the fish collides with the ejector rod 22, the ejector rod 22 can drive the baffle 32 to move upward, thereby driving the baffle 32 to disengage from the notch 31, forming a gap between the baffle 32 and the inner side wall of the inclined portion 26, and further enabling the feed in the feeding channel 9 to flow from the gap to the discharge port 8, and then flowing to the water surface through the discharge guide rail 29 to achieve feeding. After the ejector rod 22 is not subjected to an impact external force, under the action of the tension elastic member two 42, the ejector rod 22 drives the baffle 32 to move downward to reset, and the baffle 32 blocks the notch 31, so that the feed in the feeding channel 9 stops flowing out.

[0043] In this embodiment, the tension elastic member two is a tension spring, and the tension elastic member one is also a tension spring. The elastic moduli of the two springs satisfy that when the feed is not being put, the sum of the forces received by the multiple tension elastic members two is equal to the sum of the gravity of the ejector rod and the baffle, and when the feed is being put, the elastic modulus of the tension elastic member two enables the baffle to move upward by twice the diameter of the feed under the action of the impact force of the fish, so as to ensure that the feed can be reliably put.

[0044] In this embodiment, one end of the ejector rod 22 penetrates through the receiving cavity 33 from the bottom of the inducer 28 and is arranged inside the housing and abuts against a limiting device arranged in the storage cavity 20. One end of the ejector rod 22 is in smooth abutment with the groove at the bottom of the connecting block 3 in the storage cavity 20. The other end of the ejector rod 22 is fixedly provided with a rubber box 33. There are more than two air holes (not marked in the figure) on the rubber box 33. Feed for attracting fish to feed is placed inside the rubber box 33. In this embodiment, the entire rubber box 33 is immersed in water, and the feed spreads its smell into the water through the air holes to attract the fish to generate a feeding behavior and collide with the ejector rod 22.

[0045] Working principle of the utility model: Feed for attracting fish to feed is arranged on the ejector rod 22. When the ejector rod 22 is collided by a fish, the tension elastic member II 42 is pulled and rebounds to drive the baffle plate to move upward. During this process, the ejector rod 22 drives the baffle plate 32 to move upward, further driving the baffle plate 32 to disengage from the notch 31, so that a gap is formed between the baffle plate 32 and the feeding channel 9. Then the feed flows through the gap to the discharge port 8, and then flows to the water surface through the discharge guide rail 29 to achieve feeding. After the ejector rod 22 is not subjected to an external impact force, under the action of the gravity of the tension elastic member II 42 and the ejector rod component, the ejector rod 22 drives the baffle plate 32 to move downward to reset, and the baffle plate 32 blocks the notch 31, so that the feed in the feeding channel 9 stops flowing out.
