Description

TECHNICAL FIELD

[0002] Fish pond culture is a production activity of breeding, cultivating and harvesting aquatic animals under human control. Generally, it includes the whole process of breeding aquatic products from seedlings. When feeding aquatic products, the traditional feeding method is to throw and scatter feed by hand or use a shovel to throw and scatter feed to the water surface, so that the feed sinks naturally to complete the feeding of the feed. However, this feeding method limits the feeding area, as people can only stand on the shore, so many aquatic products in the center of the fish pond cannot easily eat the feed, which affects their growth. Therefore, people drive a small boat to carry feed and move on the water surface by driving the small boat, and then manually feed. However, because the sound of the engine of the small boat is too loud, the aquatic products will be scared away when the small boat passes by, so the feed cannot be well eaten and sinks to the bottom of the fish pond, resulting in waste of feed. The above-mentioned several feeding methods solve the problem of feed feeding to some extent, but the manual labor intensity is large, and the feed is not evenly distributed, so the feed cannot be eaten in time. Therefore, in order to increase the yield of aquatic products, an automatic feeding device for aquaculture is proposed. SUMMARY

[0069] In addition, the lifting assembly comprises a fixed ring 15, threaded pipes 16, lead screws 17, first gears 18, a gear ring 19, a lifting motor 20 and a second gear 21, the fixed ring 15 is fixedly installed inside the sealing shell 7, a plurality of threaded pipes 16 are circumferentially and rotatably installed on the fixed ring 15, each threaded pipe 16 is internally threadedly installed with a lead screw 17, the outer wall of each threaded pipe 16 is fixedly sleeved with a first gear 18, the gear ring 19 is rotatably arranged on the fixed ring 15, the external teeth of the gear ring 19 are engaged with the plurality of first gears 18, the lifting motor 20 is installed on the fixed ring 15, and the top output shaft of the lifting motor 20 is rotatably and penetrates the fixed ring 15, the second gear 21 is installed on the top output shaft of the lifting motor 20, the inner ring of the gear ring 19 is provided with internal teeth, the internal teeth are engaged with the second gear 21, the floating plate 9 is provided with through holes suitable for the lead screws 17 to penetrate, and the top ends of the lead screws 17 penetrate the through holes and are connected to the bottom end of the baffle 6. Since the fixed ring 15 is fixedly connected with the sealing shell 7, the lifting motor 20 is installed on the fixed ring 15, the rotation of the lifting motor 20 drives the second gear 21 to rotate, the gear ring 19 is rotatably connected with the fixed ring 15, so that the engagement of the second gear 21 with the internal teeth drives the gear ring 19 to rotate, and the rotation of the gear ring 19 drives the plurality of first gears 18 to rotate simultaneously.

[0070] The second embodiment is based on the first embodiment, and further comprises a material dispersing assembly, which comprises a material dispersing shaft 22, a fixing shaft 23, a sleeve 24, a spring 25, a first protrusion 26, a second protrusion 27, and a material dispersing rod 28. The material dispersing shaft 22 is arranged on the driving shaft 2 and located in the holding barrel 1. The fixing shaft 23 is installed above the holding barrel 1 through a support rod 29. The sleeve 24 is slidably sleeved on the outer lower side of the fixing shaft 23. The spring 25 is located in the sleeve 24 and connected to the sleeve 24 and the fixing shaft 23 at both ends. The first protrusions 26 are circumferentially arranged at the bottom of the sleeve 24. The second protrusions 27 are circumferentially arranged at the top of the material dispersing shaft 22. The material dispersing rods 28 are equidistantly installed on the outside of the sleeve 24. When the driving motor 8 rotates, the driving shaft 2 drives the material dispersing shaft 22 to rotate. The spring 25 can make the sleeve 24 and the fixing shaft 23 have telescopic property. The first protrusions 26 are circumferentially arranged and have intervals between them. Each interval can accommodate a corresponding second protrusion 27. Meanwhile, the second protrusions 27 are circumferentially arranged and have intervals between them, which can also accommodate the first protrusions 26. Therefore, when the material dispersing shaft 22 rotates, the sleeve 24 can realize reciprocating up-down movement under the action of the spring 25, thereby driving the material dispersing rods 28 to reciprocate up and down, which can continuously stir the feed placed in the holding barrel 1 in the longitudinal direction, improve the flowability of the feed moving downward, and avoid the feed from being blocked in the holding barrel 1. The material dispersing assembly further comprises a guide block 30, which is in the shape of a circular truncated cone and connected between the material dispersing shaft 22 and the driving shaft 2, thereby improving the flowability of the feed moving downward. The sleeve 24 and the fixing shaft 23 are in longitudinal sliding fit. A sliding groove can be arranged on the inner wall of the sleeve 24 along the length direction of the sleeve 24. A sliding block is arranged on the outside of the fixing shaft 23 along the length direction of the fixing shaft 23. The sliding block and the sliding groove are in sliding fit, which can avoid the sliding sleeve from rotating with the material dispersing shaft 22 and ensure the stable up-down movement of the material dispersing rods 28. The cross-sectional shape of the material dispersing rod 28 is in the shape of a rhombus, which can avoid the feed from remaining on the material dispersing rod 28 and reduce the resistance when the material dispersing rod 28 moves up and down in the feed, thereby improving the use reliability. In order to avoid the first protrusions 26 and the second protrusions 27 from being filled with feed and hindering the movement, an outer sleeve ring 31 is further sleeved on the outside of the sleeve. The outer sleeve ring 31 is fixedly connected to the sleeve and slidably sleeved on the outside of the material dispersing shaft 22.

[0071] It needs to be explained that, in order to further ensure the relative rotation effect between the driving motor 8 and the containing barrel 1, a pull rope 32 can be installed at the bottom of the sealing shell 7, and a weight 33, which can be a stone, is hung at the bottom of the pull rope 32. When the whole is placed on the water surface, the weight 33 enhances the pressure of the annular air bag 10 on the water surface, thereby enhancing the stability of the annular air bag 10 on the water surface, avoiding arbitrary rotation, cooperating with the guide plate 11 and the auxiliary plate 12, so that the whole can be kept relatively stable after reaching the required position on the water surface, improving the rotation of the driving motor 8 in the containing barrel 1 and the distribution barrel 3, and also ensuring the throwing effect of the feed, and a cover 34 is also installed at the top of the containing barrel 1 to avoid dust and impurities falling into the containing barrel 1 during normal use, thereby improving the use reliability of the whole.

[0072] In summary, the automatic feed dispensing device for aquaculture has the following advantages. When in use, the walking motor 14, the driving motor 8 and the lifting motor 20 in the device are connected to the external power supply through cables, and the places needing waterproof protection are protected. Since the device needs to move on the water surface, the cables used need to have a relatively long length, and a cable shaft that can wind the cables can be installed on the shore to facilitate the release and storage of the cables. The walking motor 14, the driving motor 8 and the lifting motor 20 can be remotely controlled by using a remote controller. The remote control of the motor belongs to the known technology of those skilled in the art, and a corresponding signal transmitter and signal receiver can be installed. By controlling the walking motor 14, the device moves in the fishpond along the direction of the guide plate 11 (the containing barrel 1 is filled with the required aquatic feed in advance), and the driving motor 8 is turned on at the same time. The driving motor 8 rotates to drive the driving shaft 2 to rotate, and under the action of the material distribution assembly, the feed continuously moves from the containing barrel 1 to the distribution barrel 3. Under the interaction of the centrifugal force and the wind force on the arc-shaped baffle 5, the arc-shaped baffle 5 is opened, and the feed is thrown outward in a rotating manner under the action of the centrifugal force and is dispensed on the water surface. As the device walks, the feed is dispensed while walking, and finally the entire area of the fishpond is fully dispensed. According to the feed dispensing situation of the aquatic products in the fishpond, the use height of the blocking ring 6 is adjusted in advance, and the number of arc-shaped baffles 5 to be opened is selected.
