DETAILED DESCRIPTION

[0032] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-12 The figure shows a specific embodiment of the automatic feeder for aquaculture of the present invention. The embodiment comprises a base frame 4 and a frame 9, the frame 9 is rotatably arranged on the base frame 4, the frame 9 covers the fuselage 3 on the outside to protect the inside, and the frame 9 is provided with a bin 8 for placing feed, a feeding mechanism for conveying feed, a feeding mechanism for driving feed for feeding, and a control mechanism for controlling the feeding position;

[0034] The feeding mechanism includes an auger motor 401, a barrel 402, an auger 404 and a coupling 404; the lower end of the barrel 402 extends into the bottom of the bin body 8, the auger 404 is coaxially sleeved in the barrel 402, the auger motor 401 is connected to the auger 404 through the coupling 404, and when the auger motor 401 drives the auger 404 to rotate, the feed in the bin body 8 is transported upward along the barrel 402 to the outlet;

[0035] The feeding mechanism includes a projection tube 1, a trigger 101, a feed pocket 102, a spring 103, a piston 104, a feed port 105 and a firing mechanism; the feed pocket 102, the piston 104 and the spring 103 are sequentially arranged in the projection tube 1, the lower end of the spring 103 abuts against the bottom of the projection tube 1, the feed port 105 is located at the upper part of the projection tube 1 and is opposite to the outlet of the barrel 402, the trigger 101 is arranged on the piston 104 and extends out of the projection tube 1, the firing mechanism is used to drive the trigger 101, the upper end of the projection tube 1 is open, the feed pocket 102 is used to receive the conveyed feed, and when the spring 103 is compressed downward and released, the feed in the feed pocket 102 is ejected from the upper end opening of the projection tube 1 and released outward;

[0036] The control mechanism includes a photovoltaic panel 6, a battery 10, a control main board 13 and a touch screen 15. The photovoltaic panel 6 is arranged on the upper part of the fuselage 3 to collect solar energy. The photovoltaic panel 6 is connected to the battery 10, and the battery 10 supplies power to the feed feeder. The control main board 13 is electrically connected to the touch screen 15. The touch screen 15 is used for the operator to input and debug data. The control main board 13 controls the start and stop of the feed transportation and feeding, and controls the rotation angle of the frame 9 and the compression amount of the spring 103 by the firing mechanism, so as to deliver the feed to the target position.

[0037] When the present invention is used, Fig.12As shown, the feeder is arranged on the shore of the aquaculture waters, and the feeder covers a rectangular area for feeding. The control program for feeding can be pre-edited into the control mainboard 13, and the feeding angle and feeding distance of the feeder can be set. The distance between the feeding position A and the feeder B is L, and the front is used as the reference. The angle between the AB line and the front is a. When working, it is adjusted according to the value set by the control module to realize automatic feeding. When the operator needs to debug, the touch screen 15 can be used for data input and debugging. For the adjustment of the angle a, it is realized by the relative rotation of the frame 9 on the base frame 4; for the adjustment of the distance L, it is realized by the compression degree of the spring 103 by the firing mechanism. Feed 801 is manually added into the warehouse 8, which can be used for automatic feeding for a period of time. The aquaculture waters are generally relatively far away from people's residences. Therefore, a photovoltaic panel 6 is set to cooperate with a battery 10 to collect solar energy for daily use of the feeder. The feeder itself is started and used during feeding time, and it is usually not working for a long time. The collection of solar energy can meet its use needs. When feeding is needed, the auger motor 401 of the feeding mechanism is started, driving the auger 404 to rotate, and transporting the feed 801 in the bin 8 to the outlet above the barrel 402. The feeding amount is accurately controlled by controlling the start and stop time of the auger motor 401. A fixed amount of feed 801 falls from the feed inlet 105 to the feed pocket 102, the firing mechanism is started, the trigger 101 is driven downward, and the spring 103 is compressed. The pressing distance of the firing mechanism on the trigger 101 is controlled according to the distance to be delivered, thereby controlling the elastic force of the spring 103. After the firing mechanism releases the resistance to the trigger 101, the spring 103 is released, and the feed pocket 102 and the feed 801 thereon are ejected by the elastic force of the spring 103, and the feed 801 is ejected from the upper end opening of the projection tube 1 to the predetermined feeding position; the piston 104 and the projection tube 1 are slidably matched to ensure the stability of the spring 103, and to keep the feed 801 on the feed pocket 102 well held and not falling into the gap. Before feeding, the frame 9 is rotated relative to the base frame 4 in advance, so that the delivery direction of the projection tube 1 corresponds to the delivery point. The fuselage 3, as the shell of the frame 9, covers each mechanism therein to protect each mechanism. The present invention can evenly arrange the feeding points in a breeding water area, accurately and quantitatively feed, effectively prevent water quality deterioration, and evenly distribute the cultured fish, shrimps and crabs, without excessive oxygen consumption in the local water body. It can adapt to outdoor environments, use solar energy for power supply, and does not require external circuits, greatly reducing breeding costs and equipment layout difficulties.

[0038] As an improved specific implementation, the firing mechanism includes a pitch-adjusting motor 301, a synchronous belt 302, a bearing seat 303, a thumbwheel 304, a slide 305, a screw 306, a bearing end seat 307, a guide rod 308 and a thumbwheel motor 309; the thumbwheel 304 and the thumbwheel motor 309 are arranged on the slide 305, the thumbwheel motor 309 is linked with the thumbwheel 304, the screw 306 is rotatably arranged between the bearing seat 303 and the bearing end seat 307, the guide rod 308 is arranged parallel to the screw 306, the slide 305 is penetrated on the screw 306 and the guide rod 308, and the pitch-adjusting The motor 301, the synchronous belt 302, and the lead screw 306 are connected in sequence for linkage. When the pitch-adjusting motor 301 drives the lead screw 306 to rotate, it drives the lead screw 306 to move, adjusts the relative distance between the dial wheel 304 and the trigger 101, and then changes the dial position of the trigger 101 by the dial wheel 304, that is, changes the compression amount of the spring 103. When the dial motor 309 drives the dial wheel 304 to rotate, it dials the trigger 101, and the control main board 13 feeds back information to the pitch-adjusting motor 301 to adjust the relative distance between the adjustment dial wheel 304 and the trigger 101, thereby adjusting the feeding distance of the feed.

[0039] like Figure 3 , 4 As shown in , 5, 9, 10, and 11, the dial wheel 304 has a plurality of teeth. When rotating around the axis, the teeth rotate to the trigger 101 and press it down, thereby compressing the spring 103. After the teeth of the dial wheel 304 rotate away from the trigger 101, that is, after the trigger 101 is released, the elastic force of the spring 103 is released to feed the feed 801. Fig. 9As shown, the relative distance between the axis of the thumbwheel 304 and the trigger 101 is L1, and the screw rod 306 and the guide rod 308 are horizontally arranged along the reciprocating direction of the relative distance, wherein both ends of the screw rod 306 are rotatably arranged on the bearing seat 303 and the bearing end seat 307, the guide rod 308 is arranged on the frame 9, and the slide 305 is penetrated by the screw rod 306 and the guide rod 308. The thumbwheel 304 and the thumbwheel motor 309 are rotatably arranged on the slide 305, and the thumbwheel 304 is driven to rotate when the thumbwheel motor 309 is started. The distance of feeding the feed 801 is achieved by adjusting the relative distance between the dial wheel 304 and the trigger 101, specifically, by relying on the setting of the adjustable distance motor 301, when it is turned on, it drives the synchronous belt 302 to rotate and then causes the screw rod 306 to rotate synchronously, and the slide 305 is meshed with the screw rod 306 and translates along the screw rod 306 when the screw rod 306 rotates, thereby achieving the adjustment of the distance L1. The smaller the L1 is adjusted, the closer the teeth of the dial wheel 304 are to the trigger 101, and the longer the time it takes for the teeth of the dial wheel 304 to rotate and contact the trigger 101 and until it is separated from the trigger 101, that is, the more the teeth of the dial wheel 304 are pressed down, the greater the elastic force accumulated by the spring 103, and the corresponding feeding distance of the feed 801 is also farther. On the contrary, the larger the adjustment of L1 is, the farther the teeth of the thumbwheel 304 are from the trigger 101, and the shorter the time it takes for the teeth of the thumbwheel 304 to rotate and contact the trigger 101 and to disengage from the trigger 101, that is, the less the teeth of the thumbwheel 304 are pressed down, the smaller the elastic force accumulated by the spring 103, and the closer the feeding distance of the corresponding feed 801 is. By inputting data on the corresponding relationship between the distance L1 and the feeding point or relying on a pre-edited program, the control system can accurately start and stop the distance adjustment motor 301 to adjust the position of the thumbwheel 304, so as to achieve accurate adjustment of the feeding distance.

[0040] As an improved specific implementation method, the base frame 4 and the frame 9 are connected through a rotating mechanism, and the rotating mechanism includes a gear motor 701, a small gear 702, a large gear 703, a bull's eye 704 and a mounting plate 705; the frame 9 is arranged on the large gear 703, the small gear 702 is arranged on the base frame 4, the gear motor 701 is installed on the base frame 4 through the mounting plate 705, the small gear 702 is connected to the gear motor 701 for driving, the small gear 702 and the large gear 703 are meshed for transmission, and a number of bull's eyes 704 for supporting the frame 9 are arranged around the gear 702 and the large gear 703 on the base frame 4, and the control main board 13 feeds back information to the gear motor 701 to adjust the orientation angle of the frame 9, thereby adjusting the feeding angle of the feed.

[0041] like Figure 7 , 8As shown in Figures 10 and 11, the pinion 702 and the large gear 703 are located in the middle of the structure of the base frame 4, and bull's eyes 704 are arranged around the frame 9 to support the frame 9. The gear motor 701 is installed at the bottom of the base frame 4 through the mounting plate 705 and connected to the pinion 702 to provide power. The large gear 703 is installed on the frame 9 and meshes with the pinion 702 for transmission. By inputting data on the corresponding relationship between the angle a and the feeding point or relying on a pre-edited program, the control system can accurately start and stop the gear motor 701 to adjust the direction of the frame 9, that is, the projection tube 1 thereon, so as to accurately adjust the feeding direction.

[0042] As an improved specific implementation method, a rotatable waterproof cover 5 is provided at the upper opening of the projection tube 1, and the waterproof cover 5 is connected to an electric cylinder 14. When feed is delivered, the electric cylinder 14 drives the waterproof cover 5 to rotate open, and after the feed is delivered, the waterproof cover 5 is rotated closed.

[0043] like Figure 1 , 2 As shown in , 3, 4, 5, 10, and 11, the waterproof cover 5 is normally closed when the feeder is not working, thereby effectively protecting the projection tube 1 from external pollution. When the feed is delivered, the control system sends a signal in advance to drive the electric cylinder 1 to drive the waterproof cover 5 to rotate and open, so as to smoothly deliver the feed 801; then the waterproof cover 5 is closed to reduce the exposure time of the projection tube 1 to the outside.

[0044] As an improved specific implementation manner, a rotatable side door 2 is provided on the body 3 at a position corresponding to the touch screen 15 .

[0047] like Figure 1 , 2As shown in Figures 3, 4, 5, 10, and 11, the bin cover 7 is normally closed to seal and protect the bin body 8 and the feed 801 stored therein, effectively protecting the feed 801 from external pollution. When feed supplement is needed, the operator opens the bin cover 7 to add feed. In addition, in order to prevent rainwater from entering the bin body 8 and contaminating the feed, a water guide trough 11 is provided at the far end edge of the bin cover 7 when it is rotated and closed, which can effectively receive rainwater and prevent rainwater from entering the bin body 8 through the edge gap of the bin cover 7. The rainwater is guided to flow away to both sides by the water guide trough 11.

[0048] As an improved specific implementation, a buffer pad 18 is provided outside the projection tube 1 at a position corresponding to the trigger 101 , and when the spring 103 is released to eject the trigger 101 , the buffer pad 18 buffers and limits the trigger 101 at the far end.

[0049] like Figure 3 , 4 As shown, when the spring 103 releases the pressure, the trigger 101 will pop out with a greater impact force. By providing the buffer pad 18, the trigger 101 can be effectively buffered, reducing the hard impact on the structure, which is beneficial to extending the service life of the component.

[0050] As an improved specific implementation, a discharge port 12 for unloading feed is provided at the bottom of the bin body 8, and a bin bottom sliding door 16 that can be slidably opened and closed is provided at the discharge port 12.

[0051] like Figure 3 , 4 As shown in Figures 5, 10 and 11, by arranging a discharge port 12 at the bottom of the bin body 8, it is convenient to discharge the remaining feed in the bin body 8 when cleaning and maintaining the equipment, and it is convenient to clean the bin body 8, or clean up the feed that may be spoiled or contaminated, thereby improving the efficiency of cleaning and maintenance; by arranging a bin bottom sliding door 16, the convenience of opening and closing the discharge port 12 is improved, and the bin bottom sliding door 16 will not be affected by the internal feed storage when sliding open, and the feed discharge rate can be controlled by controlling the size of the sliding open outlet, which is more convenient to control.

[0052] As an improved specific implementation method, a bottom door 17 that can be rotatably opened is provided on the fuselage 3 at a position corresponding to the bottom sliding door 16 of the compartment.

[0053] like Figure 1 , 5 As shown in , 10 and 11, the bottom door 17 is closed at ordinary times to isolate the bottom sliding door 16 and the discharge port 12 from the outside world, which can better protect the bottom sliding door 16 and the discharge port 12 and extend the service life of the equipment; when the operator needs to control and debug the equipment, the bottom door 17 is opened to expose the bottom sliding door 16 for operation.
