Description

Technical Field

[0001] The invention belongs to the field of aquaculture equipment, in particular to a fish pond feed delivery device. Background Art

[0002] Fish farming requires feeding feed into the fish pond every day. In the prior art, automatic feeding equipment is usually used for timed and quantitative feeding. Most feeds are granular. During the transportation of feed, vibration and friction between feeds cause some granular feeds to break and the surface to wear, resulting in a certain amount of powder. When feeding feed into the fish pond, feed powder enters the fish pond along with the granular feed. When fish eat, they will give priority to granular feed, while feed powder absorbs water and sinks to the bottom of the water or suspends in the water, causing waste. In addition, since the feed contains a large amount of organic matter, phosphorus and other components, after the feed powder enters the water, the concentration of suspended matter increases. The decomposition of organic matter in the feed consumes dissolved oxygen, resulting in hypoxia in the water body. Nitrogen, phosphorus and other components will also promote the growth of algae, affecting the ecological balance of the water body. Summary of the invention

DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0024] The fish pond feed delivery device of the present invention is as follows: Figures 1 to 8 As shown, it includes a horizontally arranged guide rail 1, which is erected just above the fish pond 100, and its two ends are fixed to both sides of the fish pond 100. A walking frame 2 is arranged on the guide rail 1, and the walking frame 2 can move along the guide rail 1. Specifically, the walking frame 2 can adopt a vehicle body with its own walking mechanism, for example, a walking motor is arranged on the walking frame 2, and a rotating shaft is arranged at both ends of the walking frame 2. Rollers are arranged at both ends of the rotating shaft, and the rollers cooperate with the guide rail 1, and the walking motor is connected to the rotating shaft at one end of the walking frame 2. It is also possible to adopt an external setting to drive the walking frame 2 to move, for example, the walking frame 2 is slidably matched with the guide rail 1, and the screw nut mechanism driven by the motor drives the walking frame 2 to move linearly along the guide rail 1.

[0025] A feed storage bin 3 is provided on the walking frame 2. The feed storage bin 3 is used to store feed. The feed adopts pellet feed. The storage capacity of the feed storage bin 3 is determined according to the amount of feed fed at a single time. When feeding each time, all the feed in the feed storage bin 3 is put into the fish pond 100. The feed is not stored in the feed storage bin 3 for a long time to prevent the feed from getting damp or getting moldy. A discharge port 4 is provided at the bottom of the feed storage bin 3. The discharge port 4 is used to discharge the feed in the feed storage bin 3. A horizontal filter cylinder 5 is provided below the feed storage bin 3. The filter cylinder 5 is provided with a plurality of evenly distributed filter holes. The diameter of the filter holes is smaller than the particle size of the pellet feed, so as to ensure that the powder in the feed can pass through the filter holes, and the pellet feed with the required particle size stays inside the filter cylinder 5, thereby realizing the screening of the powder. A powder collecting cylinder 6 is provided on the outside of the filter cylinder 5. The powder collecting cylinder 6 is used to collect the screened powder so as to recover the powder and reduce waste. A spiral conveying mechanism is provided inside the filter cylinder 5. One end of the filter cylinder 5 is connected to the discharge port 4, and the other end is connected to the spreading mechanism. The spiral conveying mechanism can push the pellet feed in the filter cylinder 5 to move. During the movement, the pellet feed keeps rolling, and the powder can fall into the powder collecting cylinder 6 through the filter holes on the filter cylinder 5. The spreading mechanism is used to spread the filtered pellet feed into the fish pond 100.

[0026] Before feeding, the present invention filters the feed through the filter cartridge 5 to screen out powder in the granular feed, preventing the powder from entering the fish pond 100 along with the granular feed, and preventing the powder from being eaten by fish in time and affecting the water quality of the pond. At the same time, the screened powder can be recycled and reused to reduce feed waste.

[0027] In the present invention, the spreading mechanism includes a vertically arranged drum 7, which is rotatably mounted on the walking frame 2, and is connected to a spreading motor 8, which can be connected to the drum 7 through transmission parts such as gears, couplings, and belts, and can drive the drum 7 to rotate. The upper end of the drum 7 is connected to the filter drum 5, and when the pellet feed moves to the end of the filter drum 5, it falls into the drum 7 and moves downward along the inner hole of the drum 7. The lower end of the drum 7 is provided with an inclined spreading pipe 9, the upper end of which is connected to the drum 7 and the lower end is open. The feed in the drum 7 falls into the spreading pipe 9, and then slides along the spreading pipe 9 into the fish pond 100. The spreading pipe 9 has a suitable length, is located below the guide rail 1, and is located above the water surface of the fish pond 100. When the drum 7 rotates, it can drive the spreading pipe 9 to rotate, thereby changing the position of the lower end of the spreading pipe 9, and transporting the pellet feed to different parts of the fish pond 100.

[0028] In order to put the feed in a more dispersed manner, a water surface receiving tray 32 is provided below the feeding pipe 9. The water surface receiving tray 32 is in the shape of a disc and is fixed on the water surface of the fish pond 100. Its upper end is higher than the water surface and the bottom of the inner cavity is lower than the water surface. There can be multiple water surface receiving trays 32. When the feeding pipe 9 is in the feeding position, the water surface receiving tray 32 is coaxial with the rotating drum 7. When the feeding pipe 9 is feeding, it rotates with the rotating drum 7, so that the feed is scattered into the edge of the water surface receiving tray 32. The edge of the water surface receiving tray 32 is connected with multiple conveying troughs 33, which are evenly distributed around the water surface receiving tray 32, and the conveying troughs 33 have various lengths. The conveying trough 33 can be a rectangular trough, which is connected to the inner cavity of the water surface receiving tray 32. The upper end of the conveying trough 33 is higher than the water surface of the fish pond 100, and the bottom of the conveying trough 33 is lower than the water surface of the fish pond 100. The bottom of the water surface receiving tray 32 is provided with a water inlet hole so that the water in the fish pond 100 can enter the water surface receiving tray 32 . There may be multiple water inlet holes, one of which is connected to a water inlet pump 34 .

[0029] When feeding, the walking frame 2 moves along the guide rail 1 to a suitable position and then stops. At this time, the lower end of the spreading pipe 9 is located above one of the water surface receiving trays 32. The feed in the feed storage bin 3 falls into the filter cylinder 5 through the discharge port 4, and the screw conveying mechanism is started. The screw conveying mechanism pushes the feed in the filter cylinder 5 to move, and the powder in the feed is screened out. When the feed moves to the other end of the filter cylinder 5, the feed falls into the rotating drum 7, and the spreading motor 8 drives the rotating drum 7 and the spreading pipe 9 to rotate, and the feed enters the spreading pipe 9, and finally falls from the lower end of the spreading pipe 9 into the position near the edge of the water surface receiving tray 32. At the same time, the water inlet pump 34 is started, and the water inlet pump 34 transports the water in the fish pond 100 to the water surface receiving tray 32, so that the water level of the water surface receiving tray 32 rises, forming a height difference with the water surface of the external fish pond 100, and the water in the water surface receiving tray 32 flows into each conveying trough 33, and flows along the conveying trough 33 to the outlet end of the conveying trough 33, and the feed in the water surface receiving tray 32 will also reach the outlet end of each conveying trough 33 with the water flow, so as to achieve the dispersed delivery of the feed. The conveying trough 33 can be three, four, etc., and the length of each conveying trough 33 can be flexibly set according to the needs. After putting an appropriate amount of feed into a water surface receiving tray 32, the walking frame 2 moves a distance so that the feeding pipe 9 is above another water surface receiving tray 32, and the feed can be put into the next water surface receiving tray 32.

[0030] In order to make full use of the space of fish pond 100 and improve economic benefits, a multi-species fish mixed breeding method is usually adopted. For example, grass carp, silver carp, and black carp are cultured in the middle layer of fish pond 100, and crucian carp, catfish, and black carp are cultured in the bottom layer of fish pond 100. The middle layer fish live in the middle and upper layers of the water body, and the lower layer fish live in the bottom layer of the water body. When feeding, if the feed is only put on the water surface, the middle and upper layer fish can eat more feed, and the lower layer fish will find it difficult to obtain enough feed, and the feed cannot be fully and reasonably utilized.

[0031] In order to allow both the middle-layer fish and the bottom-layer fish to obtain sufficient feed, the surface feed receiving tray 32 of the present invention includes an outer tray body 321 and an inner adjustment sleeve 322. The outer tray body 321 is fixedly installed, and the side wall of the outer tray body 321 is provided with a plurality of first connection ports and second connection ports arranged alternately. The conveying trough 33 is connected to the first connection port, and the second connection port is connected to the conveying pipe 35. The outlet end of the conveying trough 33 is located in the upper layer of the water body of the fish pond 100, and the feed can be conveyed to the middle and upper layers of the water body of the fish pond 100. The outlet end of the conveying pipe 35 is located in the bottom layer of the water body of the fish pond 100, and the feed can be conveyed to the bottom layer of the water body of the fish pond 100. A pressure pump 36 is provided at the outlet end of the conveying pipe 35. Since the outlet end of the conveying pipe 35 is low and the water pressure is high, it is difficult for water to automatically flow to the outlet end of the conveying pipe 35, so a pressure pump 36 is provided to promote the flow of water in the conveying pipe 35. The inner adjustment sleeve 322 is rotatably matched with the outer disk body 321. The inner adjustment sleeve 322 is provided with a plurality of connection holes, and the inner adjustment sleeve 322 is connected with a rotation drive mechanism 323. The rotation drive mechanism 323 can be a motor, which is connected to the inner adjustment sleeve 322 through a gear mechanism, and can drive the inner adjustment sleeve 322 to rotate a certain angle. When the connection hole is connected to the first connection port, the inner adjustment sleeve 322 closes the second connection port, and when the connection hole is connected to the second connection port, the inner adjustment sleeve 322 closes the first connection port.

[0032] When feeding, the water inlet pump 34 is turned on first, and the inner adjustment sleeve 322 closes each second connection port. The feed in the water surface receiving tray 32 can enter the conveying trough 33 with the water flow and move to the upper layer of the water body of the fish pond 100 for the fish in the middle and upper layers to eat. Then the water inlet pump 34 is turned off, and the rotating drive mechanism 323 is used to drive the inner adjustment sleeve 322 to rotate the set angle so that the inner adjustment sleeve 322 closes the first connection port. At this time, the second connection port is opened, and the delivery pipe 35 is connected to the inner cavity of the water surface receiving tray 32. Then the pressure pump 36 is turned on, and the pressure pump 36 delivers the water inside the delivery pipe 35 to the bottom layer of the water body of the fish pond 100. At the same time, the feed and water in the water surface receiving tray 32 enter the delivery pipe 35 and finally flow to the bottom layer of the water body of the fish pond 100 to provide feed to the bottom fish. In this process, the water in the fish pond 100 enters the water surface receiving tray 32 through the water inlet hole.

[0033] The invention can not only provide feed to the upper and middle layers of fish, but also directly transport the feed to the bottom of the water body, reasonably distribute the feed, and prevent the upper and middle layers of fish from being oversatiated while the bottom layers of fish are short of feed.

[0034] In the present invention, the spiral conveying mechanism includes a conveying motor 10, a rotating shaft 11 and a spiral conveying piece 12. The rotating shaft 11 is located in the filter cartridge 5 and is coaxial with the filter cartridge 5. The spiral conveying piece 12 is fixedly arranged on the outer wall of the rotating shaft 11. The conveying motor 10 is fixedly connected to one end of the rotating shaft 11. The conveying motor 10, the rotating shaft 11 and the spiral conveying piece 12 can adopt the existing technology.

[0035] The granular feed in the feed storage bin 3 has poor fluidity, and it is difficult to automatically and continuously enter the filter cylinder 5 through the discharge port 4, and the material is easily stuck. In the present invention, the filter cylinder 5 is connected to the discharge port 4 through a vertical feed pipe 13, and a vertical feed rod 14 is arranged in the feed pipe 13. An upper slider 15 and a lower slider 16 are fixedly arranged on the feed rod 14. The upper slider 15 and the lower slider 16 are slidably matched with the feed pipe 13. A cam 19 is arranged on the rotating shaft 11, and the lower end of the feed rod 14 is slidably matched with the cam 19. Specifically, a gate-shaped bracket can be arranged at the lower end of the feed rod 14, a limit pin is arranged at the bottom of the gate-shaped bracket, and a slide groove is arranged on the two side walls of the cam 19. The limit pin is located in the slide groove and is slidably matched with the slide groove. When the cam 19 rotates, the feed rod 14 can be driven to reciprocate linearly up and down. The upper end of the feeder rod 14 extends into the feed storage bin 3; the positions of the upper slider 15 and the lower slider 16 satisfy: when the cam 19 pushes the feeder rod 14 to move to the highest point, the upper slider 15 is located above the feed tube 13, and the lower slider 16 is located inside the feed tube 13; when the feeder rod 14 moves to the lowest point, the upper slider 15 is located inside the feed tube 13, and the lower slider 16 is located below the feed tube 13.

[0036] When the cam 19 rotates with the rotating shaft 11, it can push the material lever 14 to move up and down reciprocatingly. When the cam 19 pushes the material lever 14 to move upward, the upper slider 15 moves to the top of the feeding tube 13, and the feed in the feed storage bin 3 can enter the feeding tube 13; when the cam 19 pushes the material lever 14 to move downward, the lower slider 16 moves to the bottom of the feeding tube 13, and the feed inside the feeding tube 13 enters the filter cylinder 5 through the lower port of the feeding tube 13. Since the material lever 14 continuously moves up and down, the upper end of the material lever 14 continuously fluctuates the pellet feed near the discharge port 4, promotes the flow of pellet feed, prevents the pellet feed from getting stuck to each other and unable to enter the discharge port 4, and ensures continuous and orderly feeding.

[0037] In order to improve the feeding effect, a horizontal positioning beam 17 is provided in the feed storage bin 3, a vertical rotating sleeve 20 is provided on the positioning beam 17, a plurality of feeding blades 21 are provided on the outer wall of the rotating sleeve 20, the edges of the feeding blades 21 are in clearance with the inner wall of the feed storage bin 3, the side wall of the rotating sleeve 20 has a spiral groove extending upward from its lower end surface, the feeding rod 14 is coaxial with the rotating sleeve 20, a driving column 22 is provided on the upper outer wall of the feeding rod 14, the driving column 22 is a cylinder, and the axial direction of the driving column 22 is consistent with the radial direction of the feeding rod 14, the upper end of the feeding rod 14 is located in the rotating sleeve 20 and slides with the rotating sleeve 20, the driving column 22 is located in the spiral groove and slides with the spiral groove. When the feeding rod 14 moves up and down, the driving column 22 can push the rotating sleeve 20 to rotate, and the rotating sleeve 20 drives the feeding blades 21 to rotate, which can drive the feed to move and prevent the feed from getting stuck.

[0038] In the present invention, the rotation of the rotating shaft 11 is used as the power for shifting materials, which saves power equipment and can reduce equipment cost and energy consumption.

[0039] In order to facilitate the cleaning and recovery of the powder in the powder collecting barrel 6, an openable and closable slag cleaning door 23 is provided at one end of the powder collecting barrel 6. The opening and closing method of the slag cleaning door 23 can be any existing technology.

[0040] Specifically, the powder collecting cylinder 6 comprises an upper half cylinder 61, a lower half cylinder 62 and two end plates 63, the end plates 63 are fixedly arranged at both ends of the upper half cylinder 61, the upper half cylinder 61 is fixedly installed on the walking frame 2, the lower half cylinder 62 is inclined, and the lower end of the lower half cylinder 62 is hinged to the end plates 63, and the middle or upper part of the lower half cylinder 62 is connected with a vibration mechanism; the slag cleaning door 23 is arranged on the end plate 63 at the lower end of the lower half cylinder 62. The powder sieved out in the filter cylinder 5 falls into the lower half cylinder 62. The powder has a small particle size and is easy to adhere to the inner wall of the lower half cylinder 62, which is not easy to clean. Therefore, the present invention can use a vibration mechanism to drive the lower half cylinder 62 to vibrate. During vibration, the powder adhered to the inner wall of the lower half cylinder 62 is shaken off and slides down along the inner wall of the lower half cylinder 62 to the slag cleaning door 23. When cleaning the slag, the slag cleaning door 23 is opened to conveniently take out the powder.

[0041] The vibration mechanism can be a telescopic device such as a linear motor, which drives the lower half cylinder 62 to rotate back and forth continuously. As a preferred embodiment, in the present invention, the vibration mechanism includes a turntable 24 arranged on the outer wall of the rotating cylinder 7, the lower surface of the turntable 24 is an inclined surface or an arc surface, and the upper end of the lower half cylinder 62 is connected to the filter cylinder 5 through a spring 64, and the spring 64 is always in a stretched state, with a certain pulling force. The upper end of the lower half cylinder 62 extends beyond the end plate 63. A transmission boss 65 is arranged on the upper surface of the upper end of the lower half cylinder 62, and the upper surface of the transmission boss 65 is a plane, and the upper surface of the transmission boss 65 contacts the lower surface of the turntable 24. Since the lower surface of the turntable 24 is an uneven inclined surface or an arc surface, rather than a flat surface, the height of the lower surface of the turntable 24 at different positions is different. When the rotating drum 7 rotates, the turntable 24 rotates synchronously with the rotating drum 7, and the contact position between the lower surface of the turntable 24 and the transmission boss 65 is constantly changing. Since the height of the lower surface of the turntable 24 at different positions is different, the transmission boss 65 is driven to continuously move up and down, thereby driving the entire lower half cylinder 62 to continuously rotate, thereby realizing the vibration of the lower half cylinder 62.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
