Description

Technical Field

[0001] This invention belongs to the field of aquaculture feed feeding technology, specifically relating to a fish farming feed feeding device with adjustable distance. Background Technology

[0002] Feeding is a core aspect of aquaculture production, directly impacting the growth rate of farmed organisms, feed utilization, water quality, and economic benefits. With the rapid development of my country's aquaculture industry towards intensification, large-scale production, and facility-based operations, traditional manual feeding methods are no longer sufficient to meet the demands of modern aquaculture. Manual feeding suffers from problems such as high labor intensity, uneven feeding, low feed utilization, and imprecise control over feeding time and amount. Furthermore, long-term reliance on manual operation hinders the systematic recording and analysis of aquaculture data, making it difficult to achieve refined aquaculture management.

[0003] Chinese Patent CN221429917U, published on July 30, 2024, discloses a feed feeding device for aquaculture with adjustable distance. The device includes a feed feeding body, a shock-absorbing and load-bearing moving component, a feed grinding and mixing component, and a distance-adjusting feeding component. The feed feeding body is divided into a shock-absorbing and load-bearing moving component for supporting and moving the feed; a feed grinding and mixing component is located at the upper end of the shock-absorbing and load-bearing moving component; and a distance-adjusting feeding component is located at the upper end of the shock-absorbing and load-bearing moving component for adjusting the feeding distance. During operation, continuous feed scattering can easily lead to overly concentrated feed droplets, resulting in intense competition among fish and high local water quality load. Furthermore, lumpy feed can easily clog the discharge pipe, and wind significantly affects the scattered feed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a fish farming feed dispensing device with adjustable distance, solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a fish farming feed dispensing device with adjustable distance, including a trolley, an inverted shell mounted on the top of the trolley, and a feed storage trough fixedly connected to the top of the inverted shell.

Multiple sets of rubber blocks are fixedly connected to both sides of the upper part of the extension plate. A fixing plate is fixedly connected to both sides of the upper part of the material spreading platform. A spring is fixedly connected between the fixing plate and the irregularly shaped baffle.

[0006] Furthermore, the extrusion block is in contact with the extension rods on both sides, and the end of the extrusion block that is in contact with the extension rod is set as an inclined surface. The height of the extrusion block is the same as the sum of the heights of the two sets of extension rods.

[0007] Furthermore, grooves are provided on both sides of the limiting block, and the arc-shaped structure of the rubber block on the side near the limiting block corresponds to the groove. Multiple sets of the rubber blocks are evenly distributed above the extension plate and on both sides above the slide groove.

[0008] Furthermore, the rotating rod and the fixed rod are on the same vertical line, and both sets of the irregular baffles are attached to the top of the spreading platform.

[0009] Furthermore, a connecting frame is fixedly connected above the extension plate, and transmission rods are rotatably connected to both sides of the upper part of the connecting frame. A moving plate is slidably connected below the transmission rods. The moving plate is slidably connected above the storage tank. Multiple sets of stirring rods are fixedly connected below the moving plate and inside the storage tank. A feeding port is opened below the storage tank. Round rods are fixedly connected to both sides of the connecting frame and inside the feeding port. A baffle plate is fixedly connected below the round rods and below the feeding port. A collision plate is fixedly connected to the outer side of the connecting frame. Two sets of mounting plates are fixedly connected to the outer side of the storage tank and near the collision plate. A second sliding groove is opened on the outer side of both sets of mounting plates. A translation rod is slidably connected between the two sets of mounting plates and inside the second sliding groove. An impact block is fixedly connected to the outer side of the translation rod and between the two sets of mounting plates. A baffle is fixedly connected to the outer side of the mounting plate. A second spring is fixedly connected between the baffle and the translation rod.

[0010] Furthermore, the feeding port is an arc-shaped structure, the arc of which is the same as the arc of the swing path of the spreading platform, and the length of the baffle plate is the same as the length of the feeding port.

[0011] Furthermore, the impact block is within the rotation range of the collision plate, and the end of the collision plate away from the lower end of the connecting frame is set as an arc-shaped structure. The end of the impact block near the collision plate and the end near the storage tank are both set as arc-shaped structures.

[0012] Furthermore, motors are mounted on both sides of the top of the trolley. A threaded rod is mounted at the output end of each motor. A rectangular plate is rotatably connected to the outer side of the threaded rod. The rectangular plate is mounted on top of the trolley. A movable block is rotatably connected to the outer side of the threaded rod. A rotating shaft is rotatably connected above the movable block. A wind shield is fixedly connected above the rotating shaft. Two sets of support columns are mounted on both sides of the top of the trolley. Guide plates are fixedly connected above the two sets of support columns. A sliding groove is formed above the guide plate. A transmission plate is fixedly connected to the outer side of the wind shield. A movable rod is fixedly connected below the transmission plate and inside the sliding groove.

[0013] Furthermore, the upper end of the wind shield is set as an inclined structure, the two sets of wind shields are mirror symmetrical, and the three slots are opened in an L-shaped structure.

[0014] The advantages of this application are: (1) In this application, when the motor starts, the rotating rod drives the support plate and the feeding platform to swing back and forth, so that the feed falling from the storage tank into the feeding platform is thrown out when the feeding platform swings to the end point. At the same time, due to the back and forth swing of the feeding platform, the feed is scattered in a wave-like manner, realizing the dispersed scattering of the feed and avoiding the landing point being too concentrated, thereby affecting the feeding of the fish. Furthermore, by adjusting the position of the limiting block, the angle between the two sets of irregular baffles can be changed, thereby achieving the purpose of adjusting the feeding distance.

[0015] (2) In this application, during the swinging process of the spreading platform, the connecting frame drives the round rod, thereby driving the baffle plate, so that the position of the gap between the two sets of baffle plates can change with the swinging of the spreading platform, so that the feed can fall onto the spreading platform. At the same time, through the stirring of multiple sets of stirring rods, multiple sets of feed can be fully mixed in the storage tank. Meanwhile, the impact block continuously impacts the outer wall of the storage tank, making the feed flow more smoothly through the feeding port.

[0016] (3) In this application, the second motor is started, so that the two sets of wind shields extend toward the spreading platform to block the wind and reduce the impact of the wind on the spreading of feed. During the process of the two sets of wind shields extending toward the spreading platform, the movable rod moves along the slide groove three to tilt the two sets of wind shields toward the spreading platform to improve the wind shielding effect. When the wind shielding is not needed, the output end of the second motor rotates in the opposite direction and the wind shields return to their original position to prevent the trolley from causing inconvenience to the movement of the trolley.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0020] Example 1, as Figures 1-6 As shown, a distance-adjustable fish farming feed feeding device includes a trolley 100, an inverted shell 200 mounted on top of the trolley 100, and a feed storage trough 300 fixedly connected to the top of the inverted shell 200. A motor 101 is mounted above the trolley 100 and inside the U-shaped outer casing 200. A rotating rod 102 is mounted at the output end of the motor 101. A support plate 103 is fixedly connected above the rotating rod 102. The support plate 103 supports the spreading platform 104. The spreading platform 104 is fixedly connected above the support plate 103. When the spreading platform 104 swings left and right, it spreads the feed. A fixing rod 105 is fixedly connected above the spreading platform 104. Two sets of irregularly shaped baffles 106 are rotatably connected. The rotating rod 102 and the fixed rod 105 are on the same vertical line. Both sets of irregularly shaped baffles 106 are attached to the upper part of the spreading platform 104. An extension rod 107 is fixedly connected to the outer side of the irregularly shaped baffles 106. An extension plate 108 is fixedly connected to the upper part of the fixed rod 105. A groove 109 is opened on the inner side of the extension plate 108. A limit block 111 is slidably connected above the extension plate 108 and above the groove 109. By setting the limit block 111, the clamping of the two sets of irregularly shaped baffles 106 is controlled. The angle is adjusted to control the distance of feed distribution. Grooves are provided on both sides of the limiting block 111. The arc-shaped structure of the rubber block 110 near the limiting block 111 corresponds to the groove. Multiple sets of rubber blocks 110 are evenly distributed above the extension plate 108 and on both sides above the slide groove 109. A connecting rod 112 is fixedly connected below the limiting block 111 and inside the slide groove 109. A pressing block 113 is fixedly connected below the connecting rod 112 and between the two sets of extension rods 107. The pressing block 113 fits snugly against the two side extension rods 107. The end of the extrusion block 113 that is in contact with the extension rod 107 is set as an inclined surface. The height of the extrusion block 113 is the same as the sum of the heights of the two sets of extension rods 107. Multiple sets of rubber blocks 110 are fixedly connected to the upper sides of the extension plate 108. By setting the rubber blocks 110, when the limiting block 111 is between the two sets of rubber blocks 110, the two sets of rubber blocks 110 can hold the limiting block 111. Fixed plates 114 are fixedly connected to the upper sides of the spreading platform 104. A spring 115 is fixedly connected between the fixed plate 114 and the irregular baffle 106.

[0021] In practical use, the output of motor 101 rotates continuously left and right, causing motor 101 to drive rotating rod 102 to rotate. Rotating rod 102 then causes support plate 103 to swing left and right, which in turn causes the spreading platform 104 to swing left and right. When spreading platform 104 swings left and right, it causes fixed rod 105 to rotate around rotating rod 102. When fixed rod 105 rotates, it causes extension plate 108 to swing, causing extension plate 108 and spreading platform 104 to move together. When the feeding platform 104 swings, it can drive the two sets of fixed plates 114 to move together with the feeding platform 104. This allows the two sets of irregularly shaped baffles 106 to be held above the feeding platform 104 by the force of spring 115 and to swing with the left and right swing of the feeding platform 104. This allows the feed falling from the storage trough 300 to be quickly scattered onto the fishpond by the left and right swing of the feeding platform 104. When it is necessary to adjust the feed scattering distance, a worker can pull the limiting block 111. When the locating block 111 moves between the two sets of rubber blocks 110, the limiting block 111 can squeeze the rubber block 110, causing the rubber block 110 to deform and thus lock into the groove of the limiting block 111, thereby fixing the limiting block 111. When the limiting block 111 moves away from the end of the rotating rod 102, the limiting block 111 drives the connecting rod 112, which in turn drives the pressing block 113. This causes the pressing block 113 to stop blocking the two sets of extension rods 107, allowing the two sets of irregular baffles 106 to pass through the elastic force of the spring 115. The angle above the spreading platform 104 is reduced to gather the feed and optimize the release angle, thereby increasing the throwing distance. When the limiting block 111 moves toward the rotating rod 102, the squeezing block 113 squeezes the two sets of extension rods 107. The two sets of extension rods 107 drive the two sets of irregular baffles 106 respectively, making the angle between the two sets of irregular baffles 106 above the spreading platform 104 larger. By increasing the angle, the feed is scattered more widely, thereby shortening the effective throwing distance of the feed, so as to adjust the throwing distance of the feed.

[0022] Example 2, as Figure 2 , Figures 7-10As shown, based on Embodiment 1, a connecting frame 201 is fixedly connected to the upper part of the extension plate 108. A transmission rod 202 is rotatably connected to both sides of the upper part of the connecting frame 201. A movable plate 203 is slidably connected below the transmission rod 202. The movable plate 203 is slidably connected above the storage tank 300. Multiple sets of stirring rods 204 are fixedly connected below the movable plate 203 and inside the storage tank 300. By setting the stirring rods 204, the multiple sets of feed in the storage tank 300 can be stirred. After mixing evenly, a feeding port 205 is provided at the bottom of the storage tank 300. Round rods 206 are fixedly connected to both sides of the connecting frame 201 and inside the feeding port 205. A baffle plate 207 is fixedly connected below the round rods 206 and below the feeding port 205. The feeding port 205 has an arc-shaped structure, and the arc of the feeding port 205 is the same as the arc of the swing path of the spreading platform 104. The length of the baffle plate 207 is the same as the length of the feeding port 205. The outer side of the connecting frame 201... A collision plate 208 is fixedly connected to the side of the storage tank 300. Two sets of mounting plates 209 are fixedly connected to the outer side of the storage tank 300 and the side closest to the collision plate 208. A second sliding groove 214 is provided on the outer side of each of the two sets of mounting plates 209. A translation rod 210 is slidably connected between the two sets of mounting plates 209 and inside the second sliding groove 214. An impact block 211 is fixedly connected to the outer side of the translation rod 210 and between the two sets of mounting plates 209. By setting the impact block 211, the impact block 211 continuously impacts the storage tank 300. The impact block 211 impacts the outer wall of the feed inlet 205 to make the feed flow more smoothly. The impact block 211 is within the rotation range of the impact plate 208. The end of the cylindrical part of the impact plate 208 away from the lower end of the connecting frame 201 is set as an arc structure. The end of the impact block 211 near the impact plate 208 and the end near the storage tank 300 are both set as arc structures. A baffle 212 is fixedly connected to the outer side of the mounting plate 209. A spring 213 is fixedly connected between the baffle 212 and the translation rod 210.

[0023] In practical use, when the extension plate 108 swings, it drives the connecting frame 201 to swing as well. This causes the extension plate 108 and the connecting frame 201 to swing together, allowing the connecting frame 201 to drive two sets of round rods 206. These two sets of round rods 206 then drive two sets of baffle plates 207, ensuring that the two sets of baffle plates 207 change position according to the swing angle of the spreading platform 104. This allows feed to fall onto the spreading platform 104 during its swing. Furthermore, the connecting frame 201 drives the transmission rod 202, which in turn drives the moving plate 203, which in turn drives multiple... The set of stirring rods 204 allows multiple sets of stirring rods 204 to stir multiple different feeds in the storage tank 300, so that the different feeds are fully mixed, making it easier for the fish to eat different feeds. At the same time, the connecting frame 201 drives the collision plate 208, so that the collision plate 208 can continuously squeeze the impact block 211, so that the impact block 211 can impact the outer wall of the storage tank 300, making the feed flow more smoothly through the feeding port 205. When the collision plate 208 temporarily stops squeezing the impact block 211, the translation rod 210 returns to its original position through the second spring 213, so that the translation rod 210 drives the impact block 211 back to its original position.

[0024] Example 3, as Figures 11-13 As shown, based on Embodiment 1 or Embodiment 2, motors 301 are mounted on both sides of the upper part of the cart 100. A threaded rod 302 is mounted at the output end of the motor 301. A rectangular plate 303 is rotatably connected to the outer side of the threaded rod 302. The rectangular plate 303 is mounted on the upper part of the cart 100. A moving block 304 is rotatably connected to the outer side of the threaded rod 302. A rotating shaft 305 is rotatably connected above the moving block 304. A windbreak plate 306 is fixedly connected above the rotating shaft 305. By setting the windbreak plate 306, it extends towards the spreading platform 104 to block the wind from the spreading platform 104 and reduce the impact of wind on the feeding process. The trolley 100 is equipped with two sets of support columns 307 on both sides above. A guide plate 308 is fixedly connected above the two sets of support columns 307. A slide groove 311 is provided above the guide plate 308. By setting the slide groove 311, the movable rod 310 can move along the inner wall of the slide groove 311, thereby driving the wind shield 306 to tilt, so as to improve the wind shielding effect. The upper end of the wind shield 306 is set as an inclined structure. The two sets of wind shields 306 are mirror symmetrical. The slide groove 311 is opened as an L-shaped structure. A transmission plate 309 is fixedly connected to the outer side of the wind shield 306. A movable rod 310 is fixedly connected to the lower part of the transmission plate 309 and the inner side of the slide groove 311.

[0025] In practical use, when it is necessary to shield the spreading platform 104 from wind, the second motor 301 is started, causing its output end to rotate in the forward direction. This drives the threaded rod 302 to rotate, which in turn moves the moving block 304. The moving block 304 then moves the rotating shaft 305, which in turn moves the wind shield 306 towards the spreading platform 104. This wind shield 306 shields the spreading platform 104 from wind, reducing the impact of wind on the spreading of feed. During the movement of the wind shield 306 towards the spreading platform 104, the wind shield 306 drives the transmission... The transmission plate 309 drives the movable rod 310 to move, allowing the movable rod 310 to move along the slide groove 311. When the movable rod 310 moves to the corresponding position in the slide groove 311, the inner wall of the slide groove 311 presses against the movable rod 310, causing the movable rod 310 to force the transmission plate 309 and the wind shield 306 to rotate around the rotation axis 305, thereby achieving the purpose of tilting the wind shield 306 so that the wind shield 306 can tilt towards the spreading platform 104 to improve the wind shielding effect. When the wind shield 306 is not needed, the output end of the motor 2 301 rotates in the opposite direction to reset the wind shield 306.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
