[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Reference Figure 1-Figure 10A feed automatic delivery device for river crab breeding includes a mobile delivery component 1 and a storage component 3. The mobile delivery component 1 and the storage component 3 are connected by a positioning component 2. The mobile delivery component 1 includes a hull 21, which is arranged on the water surface. A controller 24 is arranged inside the hull 21. The controller 24 is provided with an autonomous navigation system, and uses GPS and preset map data to achieve accurate positioning and path planning. A power component 20 is arranged inside the hull 21 and located at the stern to drive the hull 21 to move along the planned path. A delivery machine for delivering river crab feed is arranged inside the hull 21 and located at the bow. The storage assembly 3 includes a storage rack 7, which is arranged on the shore land. A storage box 14 is fixed to the top of the storage rack 7 by bolts. A feeding assembly for filling feed into the feeding mechanism 22 arranged in the mobile feeding assembly 1 is provided at the bottom of the storage box 14. A dispersion assembly for preventing feed from sticking is provided inside the storage box 14. When river crabs are cultured, iced fish and special crab feed are placed in the feed barrel. The feed barrel is then placed on the boat, and the feed is sprinkled by a gourd ladle while rowing manually. This not only has low feeding efficiency, but also takes a long time. Therefore, an automated feeding mechanism 22 is used for feeding. First, the automatic feeding mechanism 22 is used to automatically feed the crabs. The main navigation system uses GPS and preset map data to achieve accurate positioning and path planning, and then the power component 20 is used to move the hull 21 along the planned path. During the movement, the crab feed is fed through the feeding mechanism 22. When the feeding is completed, the feeding mechanism 22 needs to be filled with feed. Since the ship is located in the water body and the feeding mechanism 22 is located at a higher position in the ship, the workers not only have high labor intensity when feeding, but also have the risk of falling into the water when working on the shore. Therefore, the storage box 14 of the storage component 3 is used for storage. The storage box 14 is provided with ice fresh fish and special crab feed. When the feeding mechanism 22 needs to be filled with feed, When the frozen fish and the special crab feed are stored in the storage box 14 for a long time, adhesion will occur between the frozen fish and the special crab feed, which not only affects the quality of the feed, but also makes the feed easy to be blocked when filling and feeding. Therefore, a dispersion component is used to stir and disperse the frozen fish and the special crab feed, thereby effectively avoiding the adhesion between the frozen fish and the special crab feed.

[0044] In order to realize automatic feeding of feed, in the present invention, the feeding mechanism 22 includes a ring sleeve 34, the ring sleeve 34 is fixed to the top of the hull 21 by bolts, the inner ring 35 is rotatably connected to the inner ring 35, the top of the inner ring 35 is fixed with a hopper frame 33 by bolts, the top of the hopper frame 33 is fixed with a storage hopper 32 by bolts, the bottom end of the storage hopper 32 is welded with two feeding pipes 49, the bottom end of the feeding pipe 49 is welded with a throwing hopper 50, the inside of the throwing hopper 50 is rotatably connected with a throwing frame 51 through a bearing, the bottom outer wall of the throwing hopper 50 is fixed with a throwing motor 52 by bolts, and one end of the output shaft of the throwing motor 52 passes through the throwing hopper 50 and is fixed to the throwing frame 51, and the inside of the two feeding pipes 49 and the position near the top are provided with a fixed feed for feeding. The hull 21 is provided with a swaying mechanism for driving the feeding mechanism 22 to swing left and right to expand the feed delivery range. The bottom inner wall of the hopper 32 is provided with a weight sensor 53, so as to facilitate effective judgment of the feed remaining in the hopper 32. When in use, the feed in the hopper 32 is respectively fed into the throwing hopper 50 through the two feeding pipes 49 through the quantifying mechanism, and then the throwing motor 52 is started. The throwing motor 52 rotates to drive the throwing frame 51 to rotate rapidly, so that the feed in the throwing hopper 50 is thrown onto the water surface under the action of inertia and centrifugal force. At the same time, the feeding range of the feed is further expanded through the swaying mechanism, and the vibration mechanism is used to make the feed in the hopper 50 rotate rapidly. Microvibration occurs on both sides of the storage hopper 32, which effectively prevents the feed on both sides of the storage hopper 32 from sticking to the wall. The quantitative mechanism includes a rotating shaft 55, which is rotatably connected to the inside of the feeding tube 49 through a bearing. A rotating material blocking frame 54 is fixed to the outside of the rotating shaft 55 by bolts. One end of the two rotating shafts 55 passes through the feeding tube 49 and is keyed to a driven gear 44. A quantitative motor 56 is fixed to the outer wall of the bottom of the storage hopper 32 by bolts. One end of the output shaft of the quantitative motor 56 is keyed to a driving gear 45, and the driving gear 45 is meshed with the driven gear 44. When in use, the quantitative motor 56 is started, and the quantitative motor 56 drives the driving gear 45 to rotate. The driving gear 45 rotates to cause the driven gear 44 to drive the rotating shaft 55 and the rotating material blocking frame 54 to rotate. Thereby, the feed at the bottom of the storage hopper 32 is transferred into the discharge pipe 49, so that the feed delivery amount is controlled by controlling the speed of the quantitative motor 56, and due to the setting of the rotating material blocking frame 54, the blockage between the storage hopper 32 and the discharge pipe 49 is effectively avoided. The rocking mechanism includes a rocker arm 36, which is fixed to the bottom of the hopper frame 33 by bolts, and a slide groove 37 is provided at one end of the rocker arm 36. A motor mounting frame 39 is fixed to the bottom inner wall of the hull 21 by bolts, and a servo motor 41 is fixed to the inside of the motor mounting frame 39 by bolts. A disc 40 is fixed to one end of the output shaft of the servo motor 41 by bolts, and a connecting column 38 that can fit with the slide groove 37 is rotatably connected to the top of the disc 40. When in use, by starting the servo motor 41,The servo motor 41 rotates to drive the disc 40 to rotate, and the disc 40 rotates and moves along the slide groove 37 through the connecting column 38, so that the rocker arm 36 drives the hopper frame 33 and the inner ring 35 to swing left and right around the ring sleeve 34. The vibration mechanism includes two shifting frames 42, and the two shifting frames 42 are fixed to the bottom inner wall of the hull 21 by bolts. Two vibration plates 48 are fixed to both sides of the storage hopper 32 by bolts. A rubber rod 43 is bonded to one side of the vibration plate 48, and a force rod 46 is bonded to the bottom end of the rubber rod 43. The bottom end of the rod 46 is fixed with a counterweight rod 47 that can contact the shifting frame 42 by bolts. When the hopper frame 33 swings left and right, the counterweight rod 47 contacts the shifting frame 42. At this time, the rubber rod 43 is bent by force. When the counterweight rod 47 passes over the shifting frame 42 and breaks away from the shifting frame 42, the rubber rod 43 rebounds and resets. At this time, the force-bearing rod 46 and the counterweight rod 47 will vibrate left and right, and drive the vibration plate 48 to produce micro-vibration, thereby causing the side plate of the storage hopper 32 to produce micro-vibration synchronously, and the feed stuck to the wall is shaken off.

[0045] The power assembly 20 in the present invention includes two groups of water-swinging mechanisms, both of which are arranged on the top of the hull 21, and both of which include two upright frames 29. The two upright frames 29 are internally rotatably connected with a rotating arm 28, one end of the rotating arm 28 is rotatably connected with a paddle 25 through a universal ball, and the paddle 25 is rotatably connected to the hull 21 through a connecting frame, the connecting frame is composed of an upper connecting member and a lower connecting member, and the upper connecting member and the lower connecting member are rotatably connected, the lower connecting member is fixed to the hull 21, and the upper connecting member rotates with the paddle 25, one end of the two rotating arms 28 is fixed with a driving pulley 27 by bolts, and the two driving pulleys 27 are connected by a driving belt, and one end of one of the rotating arms 28 A driven pulley 26 is fixed by bolts, a driving motor 30 is fixed to the top of the hull 21 by bolts, and one end of the output shaft of the driving motor 30 is keyed to a driving pulley 31 connected to the driven pulley 26 by belt transmission. When in use, the driving motor 30 is started, and the driving motor 30 rotates to make the driving pulley 31 drive the driven pulley 26 to rotate, and the rotation of the driven pulley 26 drives the rotating arm 28 to rotate, and the two rotating arms 28 on the same side are rotated synchronously through the transmission pulley 27. At this time, the rotation of the rotating arm 28 drives the paddle 25 to swing, and then the two sets of water-swinging mechanisms operate at the same time, thereby realizing the forward movement of the hull 21, and the steering of the hull 21 can be achieved by only starting one set of water-swinging mechanisms.

[0046] When the fresh-frozen fish and the special crab feed are stored in the storage box 14 for a long time, the fresh-frozen fish and the special crab feed will adhere to each other, which not only affects the quality of the feed, but also makes the feed easy to get clogged when it is added. Therefore, a dispersion component is used to stir and disperse the fresh-frozen fish and the special crab feed. The dispersion component in the present invention includes a dispersion rack 13, which is rotatably connected to the inside of the storage box 14 through a bearing, one end of the dispersion rack 13 passes through the storage box 14 and is keyed to a sprocket 5, and a dispersion motor 9 is fixed to the inside of the storage rack 7 by bolts, and the dispersion motor 9 outputs One end of the shaft is keyed to a sprocket 2 6, and the sprocket 2 6 is connected to the sprocket 1 5 through a chain transmission. When in use, by starting the dispersion motor 9, the dispersion motor 9 rotates to make the sprocket 2 6 drive the sprocket 1 5 to rotate, and the rotation of the sprocket 1 5 drives the dispersion rack 13 to rotate and stir and disperse the fresh ice fish and special crab feed in the storage box 14. A bucket elevator 10 is provided on one side of the storage rack 7. The conveying port on the top of the bucket elevator 10 is located above the storage box 14. Since the storage box 14 is located at a higher position, the bucket elevator 10 is used to facilitate the loading of the storage box 14.

[0047] In order to realize the rapid filling of feed into the feeding mechanism 22, the feeding assembly in the present invention includes a feeding pipe 4, which is welded to the bottom of the storage box 14 and connected to the storage box 14. A connecting shaft 12 is provided inside the feeding pipe 4, and a spiral piece 11 is fixed to the outer side of the circumference of the connecting shaft 12 by bolts, and the spiral piece 11 contacts the inner wall of the feeding pipe 4. A feeding motor 8 is fixed to the outer wall of the bottom of the storage box 14 by bolts, and one end of the output shaft of the feeding motor 8 passes through the feeding pipe 4 and is fixed to the connecting shaft 12. When in use, by starting the feeding motor 8, the feeding motor 8 rotates to make the connecting shaft 12 drive the spiral piece 11 to rotate, and the rotation of the spiral piece 11 pushes the feed at the bottom of the storage box 14 to the end of the feeding pipe 4 and fills the feeding mechanism 22 with feed.

[0048] In order to ensure accurate feeding of feed into the feeding mechanism 22, the positioning assembly 2 in the present invention includes a positioning frame 19, which is fixed to one side of the storage frame 7 by bolts, and one side of the positioning frame 19 is fixed with two inclined and symmetrically distributed positioning angle plates 17 by bolts, a blocking frame 16 is provided between the two positioning angle plates 17, and the blocking frame 16 is slidably connected to the positioning frame 19, one side of the positioning frame 19 is fixed with two tension springs 15 by bolts, and the tension spring 15 is fixed to the end of the blocking frame 16, and the three positioning rods arranged on the top of the hull 21 are rotatably connected with positioning sleeves 23, and the three positioning sleeves 23 are triangularly distributed, and one side of the positioning frame 19 is provided with a sandbag 18 for buffering the positioning sleeves 23. When in use, the three triangularly distributed positioning sleeves 23 are clamped between the two positioning angle plates 17 by controlling the hull 21. At this time, the ship is blocked by the tension spring 15 and the blocking frame 16, and the positioning sleeve 23 is buffered by the sandbag 18, so that the berthing position of the hull 21 is positioned.

[0049] This embodiment is divided into the following steps when used:

[0050] S1: First, the autonomous navigation system is used, and GPS and preset map data are used to achieve precise positioning and path planning. Then, the drive motor 30 is started. The drive motor 30 rotates to make the drive pulley 31 drive the driven pulley 26 to rotate. The driven pulley 26 rotates to drive the rotating arm 28 to rotate, and the two rotating arms 28 on the same side are rotated synchronously through the transmission pulley 27. At this time, the rotating arm 28 rotates to drive the paddle 25 to swing, and then the two sets of water-swinging mechanisms operate at the same time, so as to realize the forward movement of the hull 21. At the same time, the hull 21 can be turned by starting only one set of water-swinging mechanisms, so that the hull 21 moves along the planned path;

[0051] S2: During the movement, by starting the quantitative motor 56, the quantitative motor 56 drives the driving gear 45 to rotate, and the rotation of the driving gear 45 causes the driven gear 44 to drive the rotating shaft 55 and the rotating material stopper 54 to rotate, so that the feed at the bottom of the storage hopper 32 is transferred into the discharge pipe 49, so that the feed delivery amount is controlled by controlling the speed of the quantitative motor 56, and due to the setting of the rotating material stopper 54, the blockage between the storage hopper 32 and the discharge pipe 49 is effectively avoided, so that the feed in the storage hopper 32 passes through the two discharge pipes 49 and enters the throwing hopper 50 respectively, and then the throwing motor 52 is started, and the throwing motor 52 rotates to drive the throwing frame 51 to rotate rapidly, so that the feed in the throwing hopper 50 is thrown onto the water surface under the action of inertia and centrifugal force;

[0052] S3: While feeding, the servo motor 41 is started, and the servo motor 41 rotates to drive the disc 40 to rotate. The disc 40 rotates and moves along the slide 37 through the connecting column 38, and the rocker arm 36 drives the hopper frame 33 and the inner ring 35 to swing left and right around the ring sleeve 34, so that the feeding range of the feed is further expanded;

[0053] S4: When the hopper frame 33 swings left and right, the counterweight rod 47 contacts the shifting frame 42, and the rubber rod 43 is bent by force. When the counterweight rod 47 passes over the shifting frame 42 and is out of contact with the shifting frame 42, the rubber rod 43 rebounds and resets. At this time, the force-bearing rod 46 and the counterweight rod 47 will vibrate left and right, and the vibration plate 48 will vibrate slightly, thereby causing the side plate of the storage hopper 32 to vibrate synchronously, and the feed stuck to the wall will be shaken off.

[0054] S5: After the feeding is completed, the feeding mechanism 22 needs to be filled with feed. Since the ship is located in the water body and the feeding mechanism 22 is located at a higher position in the ship, the workers are not only labor-intensive when feeding, but also have the risk of falling into the water when working on the shore. Therefore, the storage box 14 of the storage assembly 3 is used to store the feed;

[0055] S6: When it is necessary to add feed to the feeding mechanism 22, the three triangularly distributed positioning sleeves 23 are clamped between the two positioning angle plates 17 by controlling the hull 21. At this time, the ship is blocked by the tension spring 15 and the blocking frame 16, and the positioning sleeve 23 is buffered by the sandbag 18, so that the hull 21 is positioned at the mooring position, so that the feeding mechanism 22 on the moored ship is located below the feeding assembly;

[0056] S7: Then, the feeding motor 8 is started, and the feeding motor 8 rotates to make the connecting shaft 12 drive the spiral blade 11 to rotate, and the spiral blade 11 rotates to push the feed at the bottom of the storage box 14 to the end of the feeding pipe 4 and fill the feeding mechanism 22 with feed;

[0057] S8: When the fresh-frozen fish and the special crab feed are stored in the storage box 14 for a long time, the fresh-frozen fish and the special crab feed will adhere to each other, which not only affects the quality of the feed, but also makes the feed easy to be blocked when it is added. Therefore, the dispersion motor 9 is started, and the dispersion motor 9 rotates to make the sprocket 2 6 drive the sprocket 1 5 to rotate, and the rotation of the sprocket 1 5 drives the dispersion rack 13 to rotate and stir and disperse the fresh-frozen fish and the special crab feed in the storage box 14;

[0058] S9: Since the storage box 14 is located at a relatively high position, a bucket elevator 10 is used to load the storage box 14, thereby forming an automated feed delivery system, which is simple and convenient to use.

[0059] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
