Description

Technical Field

[0001] The present invention relates to the technical field of livestock breeding, and particularly relates to an automatic feeding device for laying hens and a using method thereof. Background Art

[0002] Laying hens refer to chickens raised specifically for laying eggs to supply eggs. Different from meat chickens, the main topics in raising laying hens are to improve the quality of eggs and maintain or increase the egg production, rather than improving the quality of chicken meat.

[0003] When breeding laying hens, the feed ratios for laying hens at different stages are different. The feed ratio, as well as the timing and quantitative feeding, have significant effects on the health, egg production, and egg quality of laying hens. Manual ratio preparation and feeding not only increase the work intensity of breeders, but also make it difficult to grasp the accuracy of the ratio, the feeding time, and the amount. In order to reduce the work intensity of breeders, existing automatic feeding devices can automatically add the prepared feed into the feed trough in a fixed quantity to ensure the nutrition of laying hens. However, in existing automatic feeding devices, the position of the feed trough is generally fixed in front of the chicken coop. During feeding, not only is it easy to have uneven feed distribution, but it is also not convenient to clean the feed trough. Based on this, an automatic feeding device for laying hens and a using method thereof are proposed. Summary of the Invention

[0011] Preferably, connecting pipes connected to the mixing box and the batching box are respectively provided on the upper and lower sides of the screw feeder. First solenoid valves are fixedly provided on the connecting pipes.

[0012] Preferably, a feeding pipe is fixedly provided in the middle of the bottom of the mixing box. The feeding pipe penetrates through the inverted U-shaped support frame and is fixedly connected to a second solenoid valve.

[0013] A usage method of an automatic feeding device for laying hens includes the following steps:

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] As Figure 1-7 shown, an automatic feeding device for laying hens includes:

[0031] Multiple ingredient bins 10 for storing different types of feed for feeding. The top of the ingredient bin 10 is provided with a feeding port, and a sealing cover is provided on the feeding port. The ingredient bin 10 is set to 4-6, and the ingredient bins 10 are respectively filled with corn, soybean meal, wheat bran, fish meal, stone powder, premix (vitamins + minerals), etc. A level sensor is fixedly arranged on the inner side wall of the ingredient bin 10 to detect the remaining amount of feed in the ingredient bin 10. When the remaining amount of feed is lower than a certain amount, a feeding replenishment signal is triggered to timely remind the breeder to replenish the feed;

[0032] Multiple screw feeders 20 for uniformly proportioning and discharging different types of feed. A conveying screw is rotatably connected inside the screw feeder 20. A conveying motor is fixedly arranged on the top of the screw feeder 20, and one end of the conveying screw is fixedly connected to the output shaft of the conveying motor;

[0033] A mixing bin 30 for mixing different types of feed conveyed by the screw feeder 20 and storing them uniformly for subsequent feeding;

[0034] The ingredient bin 10 is fixedly arranged on both sides of the mixing bin 30. The screw feeder 20 is fixedly arranged between the ingredient bin 10 and the mixing bin 30 and is used to convey different types of feed in the ingredient bin 10 into the mixing bin 30. A reverse U-shaped support frame 31 is fixedly arranged at the bottom of the mixing bin 30. A feed trough 40 is arranged below the reverse U-shaped support frame 31 and is used to receive the mixed feed in the mixing bin 30. Driving mechanisms 50 for the movement of the feed trough 40 are arranged on the inner walls of both sides of the reverse U-shaped support frame 31. A weight sensor 60 and a quantitative calculation module 70 are fixedly arranged at the bottom of the mixing bin 30 and are used to measure and calculate the weight of the feed in the mixing bin 30. A control mechanism 80 is fixedly arranged on the outer wall of one side of the mixing bin 30. The control mechanism 80 is electrically connected to other electrical components through wires. The control mechanism 80 includes a PLC logic controller and an HMI touch screen and is used to input the ratio parameters of the feed, as well as the time and quantity of feeding, and complete logical operations, and at the same time issue operation instructions.

[0035] The driving mechanism 50 includes driving grooves 51 opened on the inner walls of both sides of the reverse U-shaped support frame 31. A driving motor 52 is fixedly connected to the bottom of the driving groove 51. The output shaft of the driving motor 52 is fixedly connected to a rotating shaft 53. A gear 54 is fixedly connected to the end of the rotating shaft 53. Rack bars 41 are fixedly arranged on both sides of the feed trough 40. The gear 54 is meshed with the rack bars 41. By driving the driving motor 52 to drive the rotating shaft 53 and the gear 54 to rotate, the gear 54 meshes with the rack bars 41 to move, thereby driving the feed trough 40 to move at the bottom of the mixing bin 30. Both ends of the rack bars 41 extend to the outside of both ends of the feed trough 40, so that the length of the rack bars 41 is greater than the length of the feed trough 40, facilitating the complete removal of the feed trough 40 from the bottom of the mixing bin 30. Limit bends are fixedly arranged at both ends of the rack bars 41 to prevent the rack bars 41 from disengaging from the gear 54 and affecting the movement of the feed trough 40.

[0036] When the feed trough 40 receives the mixed feed, the end of the feed trough 40 close to the chicken cages in the chicken house can be first moved to the bottom of the mixing bin 30. While feeding the feed into the feed trough 40, the feed trough 40 moves towards the square of the chicken cages at the same time, so that the feed can be evenly laid in the feed trough 40. When the feed trough 40 needs to be cleaned, the feed trough 40 is moved in the direction away from the chicken cages, which is convenient for cleaning the feed trough 40 and will not affect the chickens during cleaning.

[0037] A plurality of moving wheels 48 are evenly and fixedly arranged at the bottom of the feed trough 40. A plurality of support rods are evenly and fixedly arranged at the bottom of the feed trough 40. The moving wheels 48 are fixedly arranged at the bottom of the support rods, which can both support the feed trough 40 and improve the smoothness of the movement of the feed trough 40.

[0038] When there is no need to clean the feeding trough 40, to avoid the back-and-forth movement of the feeding trough 40, the following solution is also provided inside the feeding trough 40. Driving wheels 42 are rotatably connected to the front and rear sides inside the feeding trough 40. A conveyor belt 43 is provided between the two driving wheels 42 on both sides. One of the driving wheels 42 is fixedly connected to a rotating motor 44. The rotating motor 44 is fixedly arranged on the outer wall of the feeding trough 40. The driving wheel 42 is fixedly connected to the output shaft of the rotating motor 44.

[0039] While adding the mixed feed into the feeding trough 40, the PLC logic controller controls the rotating motor 44 to start simultaneously. The rotating motor 44 drives the driving wheel 42 to rotate. The driving wheel 42 rotates to make the conveyor belt 43 move forward, so that the feed is evenly laid in the feeding trough 40 along with the movement of the conveyor belt 43. When the conveyor belt 43 moves the length distance of the feeding trough 40, the quantitative feed is just delivered.

[0040] Baffles 45 are movably arranged at the front and rear ends of the feeding trough 40. Slide grooves 46 are formed on the inner walls of both sides of the feeding trough 40. Sliders 47 are fixedly connected to both sides of the baffle 45. The sliders 47 are slidably connected to the slide grooves 46.

[0041] Specifically, the cross-sections of the slide grooves 46 and the sliders 47 are both arranged in a T-shaped structure. By slidably connecting the sliders 47 to the slide grooves 46 and fixing the baffles 45 at both ends of the feeding trough 40, it can not only prevent the feed from falling out of the feeding trough 40 at both ends, but also be convenient for disassembly, facilitating the cleaning of the feed remaining on the conveyor belt 43 and the bottom of the feeding trough 40, and avoiding the feed remaining in the dead corners of the feeding trough 40 from mildewing and deteriorating, which affects the health of laying hens.

[0042] The weight sensor 60 and the quantitative calculation module 70 are fixedly arranged in the middle of the mixing box 30 and the inverted U-shaped support frame 31. The quantitative calculation module 70 is fixedly arranged on one side of the weight sensor 60. Before performing the weighing operation, the PLC logic controller controls the weight sensor 60 to automatically zero, improving the accurate measurement of the addition amount of different feeds and the input amount into the feeding trough 40.

[0043] Connecting pipes 21 connecting the mixing box 30 and the batching box 10 are respectively arranged on the upper and lower sides of the screw feeder 20. First solenoid valves 22 are fixedly arranged on the connecting pipes 21.

[0044] When the weight sensor 60 detects that the addition amount of the feed ingredients in the corresponding batching box 10 into the mixing box 30 reaches the set value, the PLC logic controller controls the corresponding screw feeder 20 to stop operating while closing the first solenoid valve 22, avoiding adding excessive feed into the mixing box 30.

[0045] A stirring motor is fixedly installed in the middle of the top of the mixing tank 30. The output shaft of the stirring motor is fixedly connected with a stirring rod, and stirring blades are fixedly arranged on the stirring rod. When the feed ingredients in the first ingredient tank 10 are added to the mixing tank 30, the PLC logic controller controls the stirring motor to start, driving the stirring rod and the stirring blades to rotate, so as to mix the feed added to the mixing tank 30 in sequence evenly. When the addition of the last feed ingredient to the mixing tank 30 is completed, the PLC logic controller controls the stirring motor to continue running for 5 minutes, so that the feed ingredients in the mixing tank 30 are fully and evenly mixed.

[0046] A feeding pipe 32 is fixedly installed in the middle of the bottom of the mixing tank 30. The feeding pipe 32 penetrates through the inverted U-shaped support frame 31 and is fixedly connected with a second electromagnetic valve 33. The feeding pipe 32 is located above the feed trough 40.

[0047] When the weight sensor 60 detects that the amount of the mixed feed in the mixing tank 30 delivered downward to the feed trough 40 reaches the set value, the PLC logic controller controls the second electromagnetic valve 33 to close in time to avoid excessive feed falling from the feeding pipe 32. When the weight sensor 60 detects that the feed in the mixing tank 30 is lower than a certain weight, the PLC logic controller controls the screw feeder 20 to feed the mixing tank 30 proportionally in time to ensure that there is sufficient material in the mixing tank 30 and avoid affecting the feeding of laying hens.

[0048] A method for using an automatic feeding device for laying hens includes the following steps:

[0049] Step 1: Place the entire feeding device on one side of the chicken coop, make the feed trough 40 located in front of the chicken cages in the chicken coop, and input the number, age, corresponding feed ratio parameters, total daily feed feeding amount, feeding time, and the proportion of each feed feeding amount relative to the total feeding amount of the laying hens through the HMI touch screen in the control mechanism 80.

[0050] Specifically, the ingredient tank 10, the screw feeder 20, and the mixing tank 30 of the device can be placed on one side of the chicken coop, and the feed trough 40 can be placed in a position convenient for the chickens in the chicken cages to eat in front of the chicken cages. A through groove for the feed trough 40 to pass through is opened on one side below the chicken coop, and a sealing plate is hinged on the through groove.

[0051] First, according to the growth stage of the laying hens, different feeds are added to different ingredient tanks 10. The number and age of the laying hens are input through the HMI touch screen, and the total daily required feed amount is automatically calculated. The corresponding ratios and feeding times, such as 6:00, 12:00, 18:00, and the proportion of the feeding amount at the corresponding feeding time relative to the daily total amount, such as 6:00 (40%), 12:00 (30%), 18:00 (30%), are input at the corresponding positions of different ingredient tanks 10.

[0052] Step 2: According to the parameters input by the HMI touch screen, the PLC logic controller controls the screw feeder 20 to put different types of feed in the batching bin 10 into the mixing bin 30 according to the input ratio and mix them evenly.

[0053] According to the parameters input by the HMI touch screen, the PLC logic controller controls the first solenoid valve 22 to open. According to the input sequence of the parameters of different batching bins 10, the screw feeders 20 on the corresponding batching bins 10 sequentially transport the feed into the mixing bin 30. At the same time, the stirring motor drives the stirring rod and the stirring blades to rotate to mix the feed added into the mixing bin 30. Through the monitoring of the weight sensor 60, when a kind of ingredient is added to the set value, the PLC logic controller controls the screw feeder 20 corresponding to the corresponding batching bin 10 to stop operating, and at the same time closes the first solenoid valve 22, and then transports and adds the next kind of ingredient until all the ingredients are added in proportion. After the ingredients are added, the stirring motor drives the stirring rod and the stirring blades to rotate continuously for 5 minutes, and stops after stirring them evenly.

[0054] Step 3: After the mixing of the feed is completed and the feeding time arrives, the feed in the mixing bin 30 is fed into the trough 40 on time and in a fixed quantity. While feeding, the conveyor belt 43 moves forward to evenly spread the feed in the trough 40.

[0055] When the set feeding time arrives, the PLC logic controller controls the second solenoid valve 33 to open. An infrared detection device is arranged at the bottom of the feeding pipe 32 to ensure that the feed can be accurately put into one end of the conveyor belt 43 in the trough 40. The mixed feed in the mixing bin 30 falls from the feeding pipe 32 into the lower trough 40. At the same time, the conveyor belt 43 in the trough 40 moves forward, so that the feed is evenly spread in the trough 40 along with the movement of the conveyor belt 43. And when the conveyor belt 43 moves a distance equal to the length of one trough 40, the downward feeding amount of the feed just reaches the set amount, and the second solenoid valve 33 and the conveyor belt 43 stop operating at the same time, automatically completing the timing and quantitative feeding of the feed.

[0056] Step 4: When it is necessary to clean the trough 40, the driving mechanism 50 drives the trough 40 to move and moves the trough 40 to one side of the chicken coop for easy cleaning.

[0057] When it is necessary to clean the remaining feed in the feed trough 40, start the drive motor 52 to drive the rotating shaft 53 and the gear 54 to rotate. The gear 54 meshes with the rack 41 to move, and then drives the feed trough 40 fixedly connected to the rack 41 to move away from the chicken coop from the bottom of the mixing box 30. The feed trough 40 moves through the through groove on one side of the chicken coop to the outside of the chicken coop, which is convenient for the breeding personnel to clean the feed trough. During the cleaning, the baffle 45 is cleaned from both ends of the feed trough 40, which is convenient for cleaning the feed residues falling to the bottom of the feed trough 40, and will not affect the laying hens during the cleaning process. After the cleaning is completed, move the feed trough 40 in front of the chicken cage in the chicken coop.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
