Description

Technical Field

[0001] The invention belongs to the technical field of marine aquaculture, and in particular relates to a drone for spraying fish feed based on marine aquaculture. Background Art

[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device. In modern marine aquaculture, the application of drone technology is becoming more and more widespread. Drones can automatically feed fish, greatly improving the efficiency and accuracy of feed distribution. When in use, the drone body carries a material box containing fish feed and flies to the sky above the feeding area, releases the fish feed in the material box, and sprays the fish feed in the feeding area to achieve feeding of fish.

[0003] During use, existing drones for spraying fish feed based on marine aquaculture can usually only feed one type of fish feed at a time, while more than one type of fish feed is often required in the feeding area, resulting in the need for the drone to feed repeatedly. The fish feed spraying is not convenient enough, and during the process of spraying fish feed by the drone, the fish feed usually leaves the drone under the action of its own gravity, and then naturally disperses under the action of wind. This method relies on the action of wind. When the wind action is not good, the spraying area of ​​the fish feed is small, resulting in difficulty in spraying the fish feed evenly in the feeding area, and the reliability of the fish feed spraying is insufficient.

[0040] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0041] Example 1

[0042] like Figures 1 to 11As shown, it is the first embodiment of the present invention, which provides a drone for spraying fish feed based on marine aquaculture, including a body 10; a storage barrel 20, which is fixedly mounted on the body 10, and a plurality of storage chambers 21 are arranged inside the storage barrel 20; a mixing mechanism 30, which is arranged at the bottom of the storage barrel 20 for intermittent feeding and mixing, and the mixing mechanism 30 includes a first shell 31 fixedly connected to the bottom of the storage barrel 20, and a first feed tray 32 and a second feed tray 33 are rotatably mounted on the top of the first shell 31, a first sieve plate 321 is fixedly connected to the first feed tray 32, and a second sieve plate 331 is fixedly connected to the second feed tray 33, a screw dragon assembly 34 is rotatably mounted on the bottom of the first shell 31, and an outlet 35 is opened at the end of the first shell 31; a discharging mechanism 40, a discharging mechanism The structure 40 is arranged below the mixing mechanism 30, and is used for intermittent discharge and increasing the spraying area. The discharging mechanism 40 includes a second shell 41 fixedly connected to one end of the first shell 31, and the interior of the second shell 41 is rotatably connected with a rotating shaft 42, and the rotating shaft 42 is transmission-connected to the auger assembly 34. A turntable 43 is provided below the outlet 35, and the turntable 43 is fixedly connected to the rotating shaft 42. A plurality of discharging holes 431 are provided inside the turntable 43, and a plurality of baffle plates 44 are installed at intervals inside the plurality of discharging holes 431. A plurality of levers 45 are integrally connected to the lower end of the rotating shaft 42, and a plurality of air nozzles 451 are fixedly connected to both ends of the lever 45. An air pump 46 is fixedly connected to the turntable 43, and an air passage 47 is provided inside the rotating shaft 42 and the lever 45, and the output end of the air pump 46 is communicated with the air nozzle 451 through the air passage 47.

[0043] It should be noted that the storage barrel 20 is a cylinder that penetrates from top to bottom, and a cover plate is hinged on the top of the cylinder.

[0044] When the present invention is in use, different fish materials are respectively placed in different storage chambers 21 in the storage barrel 20, and the first feed tray 32 rotates to drive the first sieve plate 321 to rotate below the storage barrel 20. Since there is no bottom plate at the bottom of the storage barrel 20 to hinder the fish materials from falling, the solid part of the first feed tray 32 except the first sieve plate 321 hinders the fish materials in the storage chamber 21 from falling, and when the first sieve plate 321 coincides with the storage chamber 21, the fish materials can pass through the first sieve plate 321 and fall into the auger assembly 34. By adjusting the rotation angle of the first feed tray 32, when the first feed tray 32 coincides with only one of the storage chambers 21, the fish materials in the storage chamber 21 fall and are fed, and the fish materials in the other storage chamber 21 are hindered by the first feed tray 32 and cannot be fed. When feeding, only one kind of fish feed is fed at this time to realize separated feeding of fish feed. When the first sieve plate 321 and the two storage chambers 21 overlap, the different fish feeds in the two storage chambers 21 can all pass through the first sieve plate 321 to fall and feed, so as to realize mixed feeding of fish feed, which is convenient for feeding multiple kinds of fish feed at one time. Compared with the traditional method, it reduces the situation that the drone needs to feed repeatedly many times, and improves the convenience of spraying fish feed. At the same time, after the second feed tray 33 rotates, it drives the second sieve plate 331 to rotate under the first sieve plate 321. Whenever the second sieve plate 331, the first sieve plate 321 and the storage chamber 21 overlap, the fish feed in the storage chamber 21 passes through the first sieve plate 321 and the second sieve plate 331 and falls into the auger assembly 34. The solid part outside the second sieve plate 331 is blocked and cannot be fed. Since the second sieve plate 331 rotates continuously, the second sieve plate 331 overlaps with the first sieve plate 321 and the storage chamber 21 cyclically, so that the fish feed in the storage chamber 21 can be intermittently fed, which is convenient for the auger assembly 34 to evenly stir and mix the fish feed. After the auger assembly 34 works, it moves and mixes the fish feed, and also drives the rotating shaft 42 to rotate. The rotating shaft 42 drives the lever 45 to rotate and then breaks up the fish feed discharged from the outlet 35, so that the fish feed is dispersed when discharged. After the air pump 46 works, it blows air to the fish feed through the air nozzle 451, which is convenient for blowing away the discharged fish feed, thereby increasing the spraying area of ​​the fish feed. Compared with the traditional method, it reduces the situation that the fish feed is difficult to spray evenly in the feeding sea area. At the same time, The rotating shaft 42 also drives the rotating disk 43 to rotate, so that the discharge hole 431 and the baffle plate 44 cyclically move to the bottom of the outlet 35. When the discharge hole 431 without the baffle plate 44 moves to the bottom of the outlet 35, the fish feed transported by the auger assembly 34 drops to the lever 45 through the outlet 35 and the discharge hole 431 to realize discharge. When the discharge hole 431 with the baffle plate 44 moves to the bottom of the outlet 35, the baffle plate 44 prevents the fish feed from falling through the outlet 35 for discharge. Since the rotating disk 43 rotates continuously and the baffle plates 44 are arranged at intervals, intermittent discharge is realized, which facilitates the fish feed to be more evenly dispersed in the feeding sea area. Among them, the frequency of intermittent discharge is adjusted by adjusting the number and interval position of the baffle plates 44, that is, during the process of one rotation of the rotating disk 43,The number of discharges and the time of discharge.

[0045] Example 2

[0046] Reference Figures 1 to 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0047] like Figures 4 to 6 As shown, the bottom of the storage barrel 20 is semicircular, and two storage chambers 21 are provided. The first feed tray 32 and the second feed tray 33 are both circular, the first sieve plate 321 and the second sieve plate 331 are both semicircular, and the first feed tray 32 is located above the second feed tray 33.

[0048] It should be noted that the first sieve plate 321 and the second sieve plate 331 are provided with sieve holes inside to slow down the falling speed of the fish feed, facilitate the subsequent auger assembly 34 to mix the fish feed, and reduce the situation where the fish feed falls too fast and accumulates in the auger assembly 34 and is difficult to stir and mix.

[0049] According to the above structure, the bottom shape of the storage barrel 20 is adapted to the shapes of the first sieve plate 321 and the second sieve plate 331, which is convenient for the fish material to fall and be fed. The shapes of the first sieve plate 321 and the second sieve plate 331 are half of the first feed tray 32 and the second feed tray 33, which is convenient for intermittent feeding when the second feed tray 33 rotates below the first feed tray 32.

[0050] like Figure 4 , Figure 5 and Figure 7 As shown, a first motor 36 is disposed above the first feed tray 32 , an output end of the first motor 36 is fixedly connected to the first feed tray 32 , and the first motor 36 is fixedly connected to the storage barrel 20 .

[0051] According to the above structure, after the first motor 36 works, the output end drives the first sieve plate 321 to rotate through the first feed tray 32. When the first sieve plate 321 does not overlap with the storage cavity 21, no feeding occurs. When the first sieve plate 321 overlaps with one storage cavity 21, only one type of fish feed is fed. When the first sieve plate 321 overlaps with both storage cavities 21, two types of fish feed are fed at the same time.

[0052] like Figure 5 , Figure 6 and Figure 7 As shown, a second motor 37 is provided below the second feed tray 33 , an output end of the second motor 37 is fixedly connected to the second feed tray 33 , and the second motor 37 is fixedly mounted on the first housing 31 .

[0053] According to the above structure, after the second motor 37 works, the output end drives the second sieve plate 331 to rotate through the second feed tray 33, and feeding is carried out when the second sieve plate 331, the first sieve plate 321 and the storage chamber 21 overlap, and no feeding is carried out when the second sieve plate 331, the first sieve plate 321 and the storage chamber 21 do not overlap, so that the second sieve plate 331 rotates cyclically to feed intermittently, so that the auger assembly 34 can evenly stir and mix the fish feed.

[0054] like Figure 7 and Figure 8 As shown, a first flange 322 is fixedly connected to the outer side of the first feed tray 32, a first rotating groove 311 is opened inside the first shell 31, the first flange 322 is rotatably matched with the first rotating groove 311, a first baffle ring 38 is provided above the first flange 322, the first baffle ring 38 is fixedly connected to the first shell 31, the first baffle ring 38 is fixedly connected to the storage barrel 20, a second flange 332 is fixedly connected to the outer side of the second feed tray 33, a second rotating groove 312 is opened inside the first shell 31, the second flange 332 is rotatably matched with the second rotating groove 312, a second baffle ring 39 is provided below the second flange 332, the second baffle ring 39 is fixedly connected to the first shell 31, and the second baffle ring 39 is fixedly connected to the second motor 37.

[0055] It should be noted that the inner diameter of the first retaining ring 38 is larger than the outer diameter of the first flange 322 , the inner diameter of the second retaining ring 39 is larger than the outer diameter of the second flange 332 , the storage barrel 20 is fixedly connected to the first shell 31 via the first retaining ring 38 , and the second motor 37 is fixedly connected to the first shell 31 via the second retaining ring 39 .

[0056] According to the above structure, the first retaining ring 38 prevents the first flange 322 from disengaging from the first rotating groove 311, thereby improving the stability of the first feed tray 32 rotating along the first shell 31, and the second retaining ring 39 prevents the second flange 332 from disengaging from the second rotating groove 312, thereby improving the stability of the second feed tray 33 rotating along the first shell 31.

[0057] like Figure 2 , Figure 3 and Fig. 9 As shown, both sides of the first shell 31 are provided with inclined inner walls 313 , and the lower ends of the inclined inner walls 313 are inclined inwards.

[0058] According to the above structure, the inclined inner wall 313 is set so that the upper end size of the first shell 31 is larger than the lower end size, which is convenient for the fish feed to fall into the auger assembly 34 more smoothly after being fed, and for the subsequent auger assembly 34 to stir and mix the falling fish feed and move it to the outlet 35.

[0059] like Figure 3 and Fig. 9As shown, the auger assembly 34 includes an auger shaft 341 rotatably connected to the bottom of the first shell 31, one end of the auger shaft 341 close to the rotating shaft 42 is fixedly connected to the first bevel gear 342, and the end of the auger shaft 341 away from the rotating shaft 42 is provided with a third motor 343, the third motor 343 is fixedly connected to the first shell 31, and the output end of the third motor 343 is fixedly connected to the auger shaft 341.

[0060] It should be noted that the auger shaft 341 is a prior art, that is, a spiral blade is welded on the shaft for stirring, mixing and moving the fish feed, which will not be described in detail here.

[0061] According to the above structure, after the third motor 343 starts working, it drives the auger shaft 341 to rotate, so that the third motor 343 stirs and mixes the two kinds of fish materials that fall from the storage barrel 20 into the auger assembly 34, and at the same time drives the fish materials to move to the outlet 35 for discharge, so that the subsequent discharging mechanism 40 can break up and blow away the fish materials.

[0062] like Fig.11 As shown, a second bevel gear 421 is fixedly connected to the rotating shaft 42 , and the second bevel gear 421 is meshed with the first bevel gear 342 .

[0063] According to the above structure, the second bevel gear 421 is meshed with the first bevel gear 342, so that after the auger assembly 34 is actuated, the rotating shaft 42 is also driven to actuate. After the third motor 343 is working, the output end drives the first bevel gear 342 to rotate through the auger shaft 341, and the first bevel gear 342 drives the rotating shaft 42 to rotate through the second bevel gear 421, so that the subsequent rotating shaft 42 drives the lever 45 to break up the fish feed, so that the subsequent rotating shaft 42 drives the turntable 43 to feed intermittently.

[0064] like Figure 3 , Fig.10 and Fig.11 As shown, two levers 45 are provided, and the two levers 45 are arranged in a vertical direction and are perpendicular to each other.

[0065] According to the above structure, compared with one lever 45 or two levers 45 arranged side by side, the two mutually perpendicular levers 45 increase the contact rate between the fish feed and the levers 45 after rotation, making it easier for the levers 45 to break up the fish feed.

[0066] like Figure 3 , Fig.10 and Fig.11 As shown, the air nozzle 451 is arranged obliquely, and the end of the air nozzle 451 faces outward.

[0067] According to the above structure, the air nozzle 451 inclined outwards is convenient for blowing the fish feed outwards to increase the spraying area of ​​the fish feed, so as to facilitate the fish feed to be more evenly dispersed in the feeding sea area.

[0068] The working principle of the present invention is as follows: when it is necessary to spray fish feed, the first motor 36 drives the first feed tray 32 to rotate at the bottom of the storage barrel 20 after working, so as to switch between feeding a single type of fish feed or mixing two types of fish feed, thereby improving the convenience of spraying the fish feed. After working, the second motor 37 drives the second feed tray 33 to rotate below the first feed tray 32, so as to feed intermittently, so as to facilitate the auger assembly 34 to evenly stir and mix the fish feed. In the process of mixing and moving the fish feed, the auger assembly 34 also drives the rotating shaft 42 to rotate, so that the rotating shaft 42 drives the lever 45 and the turntable 43 to rotate. After the lever 45 rotates, the discharged fish feed is scattered. At the same time, after the air pump 46 works, it blows the fish feed through the air nozzle 451 to increase the spraying area of ​​the fish feed. After the turntable 43 rotates, the discharge hole 431 and the baffle plate 44 are moved to below the outlet 35 at intervals, so as to discharge the feed intermittently, so as to facilitate the fish feed to be more evenly dispersed in the feeding sea area.

[0069] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
