Description

Technical Field

[0001] The invention belongs to the technical field of breeding equipment, and in particular relates to feeding equipment for crayfish seed breeding. Background Art

[0002] The feeding equipment for crayfish seedling farming is an automated device designed specifically for the growth needs of juvenile shrimp. It usually uses a spiral auger as the core, which can evenly transport the seedling feed and atomize it into the shallow water area of ​​the seedling pond. It may also be equipped with anti-clogging filters, anti-corrosion materials and water level adaptive adjustment functions to achieve precise quantitative feeding, reduce feed waste and avoid water pollution, and meet the feeding uniformity requirements of juvenile shrimp in the high-density seedling stage.

[0003] During the crayfish seedling breeding process, the bait fed by the feeding equipment can be added with appropriate amounts of nutrients such as vitamin C, vitamin E, calcium, phosphorus, etc. according to the growth needs of the juvenile shrimp and the water quality, so as to enhance the immunity of the juvenile shrimp and promote molting and crustacean hardening. However, the amount of nutrients added should not be too much, so as not to cause digestive burden on the juvenile shrimp or water pollution. After the nutrients are added to the bait, they need to be stirred to mix them evenly. In some existing technologies, the operator needs to manually add nutrients continuously during the stirring process, and this process is more troublesome, which not only wastes manpower but also increases work intensity. Therefore, in response to the above problems, a feeding equipment for crayfish seedling breeding is proposed. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention provides a combination of structures such as a protrusion and a stopper.

When the stirring blade loses contact with the protrusion, the stopper automatically resets to close the discharge port. Thus, during the stirring process, the nutrient can be automatically and quantitatively discharged, eliminating the need for the operator to manually add the nutrient, thereby reducing the workload.

[0018] The present invention provides a combination of structures such as a half gear and a rack. During the stirring process, the half-circle gear block of the half gear periodically meshes with the rack and then disengages from the rack block. As a result, the rack moves back and forth under the action of the elastic member A, and the fixed ring drives the nutrient solution tank to move synchronously, causing the nutrient solution tank to shake continuously. This can prevent the nutrient solution from settling inside the tank and agglomerating, thereby clogging the feed port.

[0019] The present invention cooperates with structures such as a moving rod and a scraper. After the feeding is completed, the moving plate can be pressed to move the moving rod so that the long rod is engaged with the groove. When the motor B is started, the scraper can be driven by the auger rod and the moving rod to continuously scrape and clean the inner wall of the feeding bin. After the cleaning is completed, the moving rod is moved in the opposite direction, and the long rod is disengaged from the groove. Therefore, the scraper will not rotate during the feeding process, thereby reducing wear. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 7 As shown, the present invention provides a feeding device for crayfish seedling breeding, including a feeding bin 1, and also including: a stirring bin 2, the stirring bin 2 is fixedly connected to the top outer wall of the feeding bin 1, the top outer wall of the stirring bin 2 is fixedly connected to a motor A6, and the output shaft of the motor A6 is fixedly connected to a stirring rod 10; a motor B7, the motor B7 is fixedly connected to the outer wall of the feeding bin 1, the output shaft of the motor B7 is fixedly connected to an auger rod 8, and the outer wall of the feeding bin 1 is provided with a feeding port 9; a cleaning mechanism 5, the cleaning mechanism 5 is provided in the inner wall of the feeding bin 1; a feeding mechanism 3, the feeding mechanism 3 is provided on the top outer wall of the stirring bin 2; a shaking mechanism 4, the shaking mechanism 4 is provided on the outer wall of the stirring bin 2;

[0030] Among them, the unloading mechanism 3 includes a nutrient tank 31, and the outer wall of the nutrient tank 31 is fixedly connected to a baffle 35; the shaking mechanism 4 includes a half gear 41, and the outer wall of the half gear 41 is meshed with a rack 43; the cleaning mechanism 5 includes a rotating ring 53, and the outer wall of the rotating ring 53 is fixedly connected to a scraper 55.

[0031] The above scheme is adopted: the feeding bin 1 is the outer shell body of the feeding equipment used for crayfish seedling breeding, and the top of the stirring bin 2 is provided with a nutrient tank 31 and a bait feeding port. Various nutrients added to the bait can be placed in the nutrient tank 31, and the bait can be poured into the stirring bin 2 from the bait feeding port through external equipment. The nutrient is automatically and quantitatively added to the bait in the stirring bin 2 through the feeding mechanism 3, and then the stirring rod 10 is driven by the motor A6 to stir and mix. After that, the bait enters the feeding bin 1, and the motor B7 drives the auger rod 8 to rotate to transport the bait. During the transportation process, the bait enters the crayfish breeding pond through the feeding port 9 on the side of the feeding bin 1 to complete the feeding. A collection container is provided at the end of the feeding bin 1 opposite to the motor B7, which can collect and recycle the bait that has not been thrown out from the feeding port 9.

[0032] like Figures 1 to 7 As shown, the stirring rod 10 is rotatably connected to the inner wall of the stirring bin 2, the auger rod 8 is rotatably connected to the inner wall of the feeding bin 1, the nutrient tank 31 is slidably connected to the top inner wall of the stirring bin 2, the half gear 41 is fixedly connected to the output shaft of the motor A6, and the rotating ring 53 is rotatably connected to the inner wall of the feeding bin 1.

[0033] Adopting the above scheme: when the motor A6 is started, the shaking mechanism 4 can be driven to make the nutrient tank 31 move continuously to prevent the internal nutrient from blocking its bottom discharge port; the cleaning mechanism 5 can automatically scrape and clean the inner wall of the feeding bin 1 after the feeding is completed, which is more convenient and does not require the operator to manually clean the bait attached to the inner wall.

[0034] like Figures 2 to 3 As shown, the inner wall of the nutrient tank 31 is fixedly connected to a telescopic rod 37, the movable end of the telescopic rod 37 is fixedly connected to a block 36, the outer wall of the bottom end of the baffle 35 is elastically connected to a fixed plate 34 through a return spring 32, and the outer wall of the fixed plate 34 is fixedly connected to a protrusion 33.

[0035] The above-mentioned scheme is adopted: the discharge port below the nutrient tank 31 is cylindrical and tubular, passing through the top outer wall of the stirring chamber 2, and its inner diameter is the same as the diameter of the stopper 36. Under normal circumstances, the return spring 32 causes the fixed plate 34 and the protrusion 33 to be in a certain position due to the elastic force. Since the stopper 36 is fixedly connected to the outer wall of the fixed plate 34, the stopper 36 remains in a fixed state. At this time, the stopper 36 contacts the inner wall of the cylindrical discharge port below the nutrient tank 31, closing the discharge port so that the nutrient therein will not fall into the stirring chamber 2; the protrusion 33 is hemispherical, and its arc surface is always facing downward. The outer wall of the stirring rod 10 is provided with multiple groups of stirring blades. When the stirring rod 10 rotates, the top group of stirring blades will contact the arc surface of the protrusion 33 and squeeze it to move it upward.

[0036] like Figures 2 to 3As shown, one end of the return spring 32 is fixedly connected to the outer wall of the fixed plate 34, the other end of the return spring 32 is fixedly connected to the outer wall of the baffle 35, the stopper 36 contacts the inner wall of the nutrient tank 31, and the fixed plate 34 is slidably connected to the inner wall of the nutrient tank 31.

[0037] The above scheme is adopted: during the rotation of the stirring rod 10, multiple groups of stirring blades will continuously contact the arc surface of the protrusion 33, and the protrusion 33 will be forced to drive the fixed plate 34 to move upward synchronously. Since the baffle 35 is fixed to the outer wall of the nutrient tank 31, the fixed plate 34 compresses the return spring 32 when it moves, and can drive the stopper 36 to move upward synchronously through the fixed plate 34. When the stopper 36 moves, the movable end of the telescopic rod 37 moves toward the fixed end; when the stopper 36 moves to break away from the inner wall of the discharge port below the nutrient tank 31, it is located above the inner part of the nutrient tank 31, that is, The discharge port can be opened, and the nutrients in the nutrient tank 31 can fall into the mixing chamber 2 through the opening between the stopper 36 and the discharge port; when the stirring rod 10 rotates until the stirring blade is out of contact with the protrusion 33, the elastic force of the reset spring 32 will cause the fixed plate 34 and the protrusion 33 to move downward and reset, and the stopper 36 moves synchronously and contacts the inner wall of the discharge port again to close the discharge port, so that the stirring blade is constantly in contact with and squeezed with the protrusion 33, thereby achieving the effect of automatically and quantitatively adding nutrients during the stirring process, eliminating the need for the operator to manually add for a long time, reducing work intensity.

[0038] like Figures 4 and 5 As shown, a fixing ring 44 is fixedly connected to the outer wall of the nutrient tank 31 , and the nutrient tank 31 is elastically connected to the inner wall of the mixing chamber 2 via an elastic member A42 .

[0039] The above solution is adopted: the fixing ring 44 connects the nutrient tank 31 and the rack 43. When the rack moves, the nutrient tank 31 will move along with it in the top inner wall of the mixing chamber 2, and will compress the elastic part A42 during its movement. It can be moved and reset under the elastic force of the elastic part A42, thereby achieving the effect of reciprocating movement.

[0040] like Figures 4 and 5 As shown, the fixing ring 44 is fixedly connected to the rack 43, the rack 43 is slidably connected to the top outer wall of the mixing chamber 2, the half gear 41 is meshed with the rack 43, and the half gear 41 is rotatably connected to the top outer wall of the mixing chamber 2; one end of the elastic member A42 is fixedly connected to the inner wall of the mixing chamber 2, and the other end of the elastic member A42 is fixedly connected to the outer wall of the nutrient tank 31.

[0041] The above scheme is adopted: the tooth block on the outer wall of the half gear 41 is only provided with half a circle. When the half gear 41 is driven to rotate one circle by the output shaft of the motor A6, the half circle tooth block will engage with the rack 43 and drive the rack 43 to move linearly. The rack 43 drives the nutrient tank 31 to move synchronously through the fixing ring 44, compressing the elastic part A42; when the half gear 41 rotates until the tooth block is out of contact with the rack 43, the rack 43 and the nutrient tank 31 will be reset under the elastic force of the elastic part A42, and in the process of the movement of the nutrient tank 31, the protrusion 33 can always contact the outer wall of the stirring blade, so that when the motor A6 is started, not only can the nutrient agent be automatically and quantitatively discharged, but also the nutrient tank 31 can be driven to continuously move back and forth linearly, so that the nutrient tank 31 is constantly shaking to prevent the nutrient agent inside from caking the discharge port.

[0042] like Figures 6 and 7 As shown, a groove 54 is provided on the outer wall of the rotating ring 53, a moving rod 51 is slidably connected to the inner wall of the auger rod 8, a long rod 52 is fixedly connected to the outer wall of the moving rod 51, the inner wall of the moving rod 51 is elastically connected to a moving plate 57 through an elastic member B56, a square block 58 is fixedly connected to the outer wall of the moving plate 57, and a square groove 59 is provided on the inner wall of the auger rod 8.

[0043] The above-mentioned scheme is adopted: the rotating ring 53 can rotate in the inner wall of the feeding bin 1, and the two groups of scrapers 55 will move along the inner wall of the feeding bin 1 during rotation, so as to scrape off the bait attached to the inner wall of the feeding bin 1; the moving rod 51 can only move laterally in the inner wall of the auger rod 8 and cannot rotate, and the upper part of the moving rod 51 protrudes from the outer wall of the auger rod 8, and the operator can hold it to move the moving rod 51; there are two groups of square grooves 59, and the position of the moving rod 51 can be fixed by clamping the square block 58 with the square groove 59, so that the moving rod 51 can be fixed at two positions.

[0044] like Figures 6 and 7 As shown, the long rod 52 is engaged with the groove 54, the scraper 55 is in contact with the inner wall of the feeding bin 1, the movable plate 57 and the square block 58 are both slidably connected to the inner wall of the movable rod 51, and the square block 58 is engaged with the square groove 59; one end of the elastic member B56 is fixedly connected to the outer wall of the movable plate 57, and the other end of the elastic member B56 is fixedly connected to the inner wall of the movable rod 51.

[0045] The above scheme is adopted: the top of the movable plate 57 protrudes from the top outer wall of the movable rod 51. When the operator presses this point, the movable plate 57 can be moved vertically in the inner wall of the movable rod 51. When the movable plate 57 moves downward, it can drive the square block 58 to move synchronously, compress the elastic member B56, and make the square block 58 disengage from the square groove 59, so that the limit of the movable rod 51 can be released to move it horizontally; when the movable rod 51 moves, it will drive the long rod 52 to move synchronously. When the long rod 52 moves to engage with the groove 54, the square block 58 corresponds to the position of the right group of square grooves 59. At this time, the movable plate 57 is released. Under the elastic force of the elastic member B56, the movable plate 57 and the square block 58 will move upward and reset synchronously, and the square block 58 is inserted into the right square groove 59 to fix the movable rod 51. At this time, the motor B7 is started, and the rotation of the auger rod 8 will drive the moving rod 51 to rotate synchronously. The moving rod 51 drives the rotating ring 53 to rotate through the long rod 52, and the inner wall of the feeding bin 1 can be scraped and cleaned through the scraper 55; on the contrary, when the moving plate 57 is pressed and the moving rod 51 is moved in the opposite direction, the long rod 52 can be disengaged from the groove 54 and fixed by the square block 58 and the left square groove 59. At this time, when the auger rod 8 and the moving rod 51 rotate, the long rod 52 cannot drive the scraper 55 to rotate, so that the inner wall of the feeding bin 1 can be cleaned in a concentrated manner after the feeding is completed. Compared with some existing technologies, the scraper 55 continues to rotate for cleaning during the rotation and feeding process of the auger rod 8, which reduces the friction between the scraper 55 and the inner wall of the feeding bin 1 and reduces the wear of the scraper 55.

[0046] The working principle and use process of the present invention:

[0047] The operator can pour the bait into the mixing bin 2 from the bait feed port at the top of the mixing bin 2 through an external device, and load the required nutrients, such as vitamins, minerals, etc., into the nutrient tank 31. In the initial state, the stopper 36 closes the discharge port to prevent leakage of the nutrients; turn on the motor A6, and its output shaft drives the stirring rod 10 to rotate. At the same time, the half gear 41 rotates synchronously with the output shaft of the motor A6. When the stirring rod 10 rotates, the top stirring blade periodically squeezes the hemispherical arc surface of the protrusion 33, and the fixed plate 34 is driven to move upward through the protrusion 33, compressing the return spring 32, and the stopper 36 moves upward synchronously, opening the discharge port of the nutrient tank 31, and the nutrients fall into the mixing bin 2. After the stirring blade is separated from the protrusion 33, the return spring 32 is reset, and the stopper 36 re-closes the discharge port, realizing a cycle of quantitatively adding nutrients every time the stirring blade contacts the protrusion. There is no need for the operator to manually add nutrients, which is more convenient.

[0048] When the half gear 41 rotates, the half-circle gear block engages the rack 43, driving the nutrient tank 31 to move horizontally through the fixing ring 44, compressing the elastic part A42. After the gear block of the half gear 41 disengages from the rack 43, the elastic part A42 is reset, and the nutrient tank 31 is reset. Therefore, the nutrient tank 31 can be moved back and forth while stirring and quantitatively discharging, shaking the internal nutrient to prevent lumps from clogging the discharge port; the stirring rod 10 rotates to fully mix the nutrient and bait to form a uniform mixture.

[0049] After the mixing is completed, the motor B7 is turned on, and its output shaft drives the auger rod 8 to rotate in the feeding bin 1. The auger rod 8 transports the mixture falling from the mixing bin 2 along the inner wall of the feeding bin 1 through the spiral blades. During the process, the mixture falls evenly into the crayfish breeding pond from the feeding port 9. The collecting container at the end of the feeding bin 1 receives the bait that has not been thrown out from the feeding port 9, which can be recycled to avoid waste. During the feeding process, the long rod 52 is not engaged with the groove 54, and the rotating ring 53 and the scraper 55 are in a stationary state.

[0050] After the feeding is completed, the operator can press the movable plate 57 to compress the elastic part B56, the square block 58 disengages from the square groove 59, and moves the movable rod 51 horizontally to make the long rod 52 snap into the groove 54 of the rotating ring 53, loosen the movable plate 57, and the elastic part B56 resets, and the square block 58 snaps into the right square groove 59 to fix the movable rod 51; start the motor B7, the auger rod 8 rotates to drive the movable rod 51 and the long rod 52 to rotate synchronously, and then drive the rotating ring 53 to rotate on the inner wall of the feeding bin 1, and the scraper 55 on the outside of the rotating ring 53 moves along the inner wall of the feeding bin 1 to scrape off the attached bait residue; after cleaning is completed, make sure that the scraper 55 moves to a position that will not close the feeding port 9, then press the movable plate 57 and pull the movable rod 51 to move in the opposite direction, the long rod 52 disengages from the groove 54, and the square block 58 snaps into the left square groove 59, stopping the rotation of the scraper 55 to avoid scraper wear during feeding.
