Description

Technical Field

[0001] The present invention belongs to the technical field of pig farming, and in particular relates to a fully automatic precision dosing device. Background Art

[0002] In the pig farming industry, medication prevention or treatment is necessary to protect pig health and prevent mortality from illness and other causes. Among the many medication methods, the most common are hand-administered medication, injections, and drinking water. Hand-administered medication is prone to cross-contamination due to frequent contact between operators and the drug surface. Injections involve human contact with the pigs, and incomplete needle disinfection can lead to further spread of the disease. Drinking water medication automatically injects medication into the pig feed trough through a pipeline, requiring minimal human involvement and allowing the system to operate fully automatically, making it simple, convenient, and hassle-free.

[0003] At present, although automatic dosing devices are used for drug administration through drinking water, personnel are still required to weigh the corresponding drugs according to the dosage every day and put them into the dosing device. The operation is cumbersome, and there is a possibility of incorrect weighing when the personnel operate. For example, if the weight is too little, the drug concentration will be low and there will be no therapeutic effect. If the weight is too much, the drug concentration will be too high, and serious poisoning of the pigs will occur.

[0004] Therefore, how to solve the above problems has become a key research topic in the prior art. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a fully automatic precision dosing device to solve the above-mentioned problems.

[0006] To achieve the above-mentioned purpose, the present invention discloses a fully automatic precision dosing device, comprising:

[0007] The medicine bin is used to temporarily store medicines, and a medicine bin discharging device is provided at the lower part of the medicine bin;

[0008] A medicine dispensing device for a medicine bin is used to control the dispensing of medicine from the medicine bin, and comprises a medicine dispensing motor, a primary gear, a secondary gear, a counterweight, and a medicine dispensing rotating plate. The rotating shaft of the medicine dispensing motor is connected to the primary gear, and the rotating shaft of the medicine dispensing rotating plate is connected to the secondary gear. The primary gear and the secondary gear are meshed, and the number of teeth of the primary gear and / or the secondary gear is incomplete. One side of the medicine dispensing rotating plate forms a seal with the medicine dispensing hole of the medicine bin, and the counterweight is installed on the other side.

[0009] The weighing bin is located at the lower part of the medicine bin dispensing device and is used to receive and weigh the weight of the medicine dispensed from the medicine bin in real time, so that when the weight of the medicine reaches the set value, the medicine is automatically dispensed into the designated position.

[0010] Compared with the prior art, the present application has the following effects: the medicine is first stored in the medicine bin, and when the medicine needs to be dispensed, the medicine dispensing motor drives the first-level gear to rotate, and then the first-level gear drives the medicine dispensing turntable to rotate through the second-level gear, thereby opening the medicine dispensing hole, and the medicine falls from the medicine bin into the weighing bin, and the weighing bin monitors the weight of the medicine in real time; it should be noted that because the number of teeth of the first-level gear and / or the second-level gear is incomplete, the two will be out of mesh for a period of time during the rotation process. At this time, the medicine dispensing turntable will reset and close the medicine dispensing hole under the action of the counterweight block, and when the two are engaged again, the medicine dispensing hole will open again; therefore, when the weight of the medicine is about to reach the set value, the medicine dispensing motor will continue to rotate. When the first-level gear and the second-level gear are not engaged, the medicine dispensing motor stops working. At this time, the medicine dispensing turntable is reset under the action of the counterweight block, closes the medicine dispensing hole, and the medicine in the weighing bin meets the set value requirements.

[0011] In summary, through the design of this application, there is no need to manually add medicine when administering the medicine, which not only reduces the risk of cross-infection caused by manual touching of the medicine, but also enables automatic and accurate drug administration, avoiding problems caused by over-dosing or under-dosing.

[0012] Furthermore, the first-stage gear is half-toothed, and the second-stage gear is full-toothed.

[0013] Furthermore, the interior of the medicine bin is a conical smooth surface and a partition is provided in the middle, and the partition is used to divide the medicine bin into two parts.

[0014] Furthermore, the surface of the partition plate is smooth, and the bottom thereof is connected to two inner folding plate surfaces and is opened with the bottom of the medicine bin, thereby forming two independent and unconnected medicine delivery holes.

[0015] Furthermore, a medicine bin cover is provided on the top of the medicine bin, a sealing gasket is installed inside the medicine bin cover, and the outside of the medicine bin cover is detachably connected to the medicine bin.

[0016] Furthermore, a stirring device is provided in the medicine bin to prevent the medicine from arching.

[0029] 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.

[0030] like Figure 1-3 As shown, the present invention discloses a fully automatic precision dosing device, comprising:

[0031] The medicine bin 1 is used to temporarily store medicines. A medicine bin dispensing device 2 is provided at the lower part of the medicine bin 1;

[0032] The medicine dispensing device 2 is used to control the dispensing of medicine from the medicine bin 1. The medicine dispensing device 2 includes a medicine dispensing motor 21, a primary gear 22, a secondary gear 23, a counterweight 24, and a medicine dispensing rotating plate 25. The rotating shaft of the medicine dispensing motor 21 is connected to the primary gear 22, and the rotating shaft of the medicine dispensing rotating plate 25 is connected to the secondary gear 23. The primary gear 22 and the secondary gear 23 are meshed, and the number of teeth of the primary gear 22 and / or the secondary gear 23 is incomplete. One side of the medicine dispensing rotating plate 25 forms a seal with the medicine dispensing hole of the medicine bin 1, and the counterweight 24 is installed on the other side.

[0033] The weighing bin 3 is located at the lower part of the medicine bin dispensing device 2 and is used to receive and weigh the weight of the medicine dispensed from the medicine bin 1 in real time, so that when the weight of the medicine reaches the set value, the medicine is automatically dispensed into the designated position.

[0034] Among them, the medicine bin 1 and the weighing bin 3 are respectively installed on the upper and lower parts of the bracket 6. The internal structure of the medicine bin 1 is a conical smooth surface with an opening at the bottom. The medicine flows smoothly to the lower medicine hole by its own weight. The upper part of the weighing bin 3 is an open structure and the interior is smooth. It is used to receive the medicine dropped by the medicine turn plate 25 and weigh the weight of the medicine in real time. A medicine barrel 7 is set at the lower part of the weighing bin 3. When the weight of the medicine weighed by the weighing bin 3 reaches the set value, it puts the medicine into the medicine barrel 7.

[0035] Compared with the prior art, the present application has the following effects: the medicine is first stored in the medicine bin 1, and when the medicine needs to be dispensed, the medicine dispensing motor 21 works to drive the first-level gear 22 to rotate, and then the first-level gear 22 drives the medicine dispensing rotary plate 25 to rotate through the second-level gear 23, thereby opening the medicine dispensing hole, and the medicine falls from the medicine bin 1 into the weighing bin 3, and the weighing bin 3 monitors the weight of the medicine in real time; it should be noted that because the number of teeth of the first-level gear 22 and / or the second-level gear 23 is incomplete, the two will be out of mesh for a period of time during the rotation process. At this time, the medicine dispensing rotary plate 25 will reset and close the medicine dispensing hole under the action of the counterweight block 24, and when the two are engaged again, the medicine dispensing hole will open again; therefore, when the weight of the medicine is about to reach the set value, the medicine dispensing motor 21 will continue to rotate, and when the first-level gear 22 and the second-level gear 23 are not engaged, the medicine dispensing motor 21 stops working. At this time, the medicine dispensing rotary plate 25 is reset under the action of the counterweight block 24, closes the medicine dispensing hole, and the medicine in the weighing bin 3 meets the set value requirements.

[0036] In summary, through the design of this application, there is no need to manually add medicine when administering the medicine, which not only reduces the risk of cross-infection caused by manual touching of the medicine, but also enables automatic and accurate drug administration, avoiding problems caused by over-dosing or under-dosing.

[0037] Following the above embodiment, more specifically, Figure 4 As shown, in an optimal embodiment, the first-stage gear 22 is half-toothed and the second-stage gear 23 is full-toothed. With this design, the first-stage gear 22 rotates one circle, and the second-stage gear 23 rotates half a circle. That is to say, during the time when the first-stage gear 22 rotates one circle, the drug dispensing turntable 25 is in the open state for half of the time to discharge the material, and the other half of the time, due to the action of the counterweight block 24, the drug dispensing turntable 25 is in the closed state. In summary, the state of the drug dispensing turntable 25 is accurately calculated through time, and then combined with the drug weight signal given by the weighing bin 3, the drug dispensing motor 21 is controlled to work, thereby ensuring that the weight of the drug in the weighing bin 3 meets the requirements.

[0038] In other embodiments, if the first-stage gear 22 is full-toothed and the second-stage gear 23 is half-toothed, if the toothless portion of the second-stage gear 23 is facing the first-stage gear 22 when it stops, then when the first-stage gear 22 rotates, it will pass through the toothless portion of the second-stage gear 23, and it will be difficult for the two to engage, which will affect the feeding; if the first-stage gear 22 has too many teeth, it means that the first-stage gear 22 and the second-stage gear 23 are engaged for a long time. Although the drug feeding efficiency is high, it is difficult to control the feeding amount. For example, when the weighing bin 3 feedback drug weight is close to the set value, the first-stage gear 22 needs to continue to rotate until the toothless portion contacts the second-stage gear 23, and the drug feeding turn plate 25 will be closed, which may cause excessive drug feeding; on the contrary, if the first-stage gear 22 has too few teeth, the drug feeding turn plate 25 is open for a short time within the time when the first-stage gear 22 rotates one circle, which will result in low drug feeding efficiency.

[0039] In summary, after many experiments and verifications, the best relationship between the number of teeth is that the first-stage gear 22 has half teeth and the second-stage gear 23 has full teeth.

[0040] Continuing with the above embodiment, more specifically, the interior of the medicine bin 1 is a conical smooth surface and a partition plate 11 is provided in the middle thereof, and the partition plate 11 is used to divide the medicine bin 1 into two parts. By designing the partition plate 11, the medicine bin can hold two kinds of medicines.

[0041] Furthermore, the surface of the partition plate 11 is smooth, and its bottom is connected to two inner folding plate surfaces and has an opening at the bottom of the medicine bin 1, thereby forming two independent and unconnected drug delivery holes, so that there will be no intersection when the two drugs are delivered, so that the two drugs exist in the medicine bin 1, which can meet the two-week medication needs of the piglet, and a medicine bin drug delivery device 2 is installed under each drug delivery hole, which can control which drug is delivered according to needs.

[0042] Continuing with the above embodiment, it is more preferred that, in order to prevent moisture from entering the medicine bin 1, a medicine bin cover 4 is provided on the top of the medicine bin 1, a sealing gasket is installed inside the medicine bin cover 4, and its outside is detachably connected to the medicine bin 1 to ensure a tight seal. In one embodiment, the medicine bin cover 4 is connected to the medicine bin 1 by a snap fastener.

[0043] Following the above embodiment, it is more preferred that Figure 2 As shown, a stirring device for preventing the medicine from arching is provided in the medicine bin 1. The stirring device can solve the problem of improper drug administration caused by the arching of the medicine.

[0044] Specifically, the stirring device includes a stirring rod 5, the upper end of the stirring rod 5 is connected to the medicine chamber cover 4, and the lower end is connected to the medicine dispensing turntable 25. Therefore, during the rotation of the medicine dispensing turntable 25, the stirring rod 5 will be driven to move up and down. The stirring rod 5 does not need to be connected to a power mechanism to achieve the purpose of breaking the arch.

[0045] Following the above embodiment, it is more preferred that Figure 5 As shown, the stirring rod 5 includes a flexible main shaft 51, a longitudinal stirring ring 52 and a transverse stirring rod 53. The flexible main shaft 51 is connected to multiple longitudinal stirring rings 52, and the transverse stirring rod 53 is connected to the longitudinal stirring ring 52. Among them, the flexible main shaft 51 has a stretching effect, and the surface of the stirring rod 5 is smooth. When the drug dispensing turn plate 25 is turned, the flexible main shaft 51 will follow the up and down movement, the longitudinal stirring ring 52 will also move longitudinally at the same time, and the transverse stirring rod 53 will move transversely, so that the medicine chamber 1 has both transverse and longitudinal disturbances, which can fully stir the temporarily stored drugs and avoid drug agglomeration, arching, etc. At the same time, this stirring and arch-breaking structure does not require an additional stirring motor, and only needs to use the movement of the original drug dispensing motor 21 to achieve the arch-breaking effect, reducing costs.

[0046] Continuing with the above embodiment, more specifically, the weighing bin 3 includes a weighing medicine bin 33, a weighing sensor 32 and a weighing medicine dispensing device 31. The weighing medicine bin 33 is smooth inside and open on the top, and is used to receive the medicine dropped by the medicine dispensing turn plate 25. The weighing sensor 32 is connected to the weighing medicine bin 33 for real-time monitoring of the medicine weight. The weighing medicine dispensing device 31 is used to control the dispensing of medicine from the weighing medicine bin 33, and the weighing medicine dispensing device 31 has the same structure as the medicine bin dispensing device 2.

[0047] Continuing with the above embodiment, more specifically, the device further includes a control system, which is electrically connected to the weighing sensor 32, the weighing and dispensing device 31, and the medicine storage dispensing device 2. The control system controls the operation of the weighing and dispensing device 31 and the medicine storage dispensing device 2 based on the drug weight information fed back by the weighing sensor 32, and uploads the drug data to the cloud platform. Through the design of the control system, the device can be automatically controlled, eliminating behaviors such as under-dosing, over-dosing, non-dosing, missed dosing, and random dosing. The entire process is traceable, and medication information is accurately recorded and reported, effectively ensuring the treatment effect.

[0048] The workflow of this application is:

[0049] 1. The user can put one or two drugs into the medicine chamber 1 at a time by opening the medicine chamber cover 4 according to medication needs;

[0050] 2. According to the type of pigs and the intake of different medicines, the system automatically controls the medicine dispensing motor 21 to rotate, driving the first gear 22 to rotate and mesh with the second gear 23. The medicine dispensing rotating plate 25 rotates a certain angle accordingly, the medicine dispensing hole is in the open state, and the medicine automatically falls into the weighing medicine bin 33;

[0051] 3. When the toothless portion of the first gear 22 is not engaged with the second gear 23, the drug delivery rotating plate 25 is automatically closed due to the gravity imbalance caused by the counterweight 24, completing one drug delivery.

[0052] 4. The control system compares the data sent back by the weighing sensor 32 to see if the dosage is met. If not, it controls the medicine dispensing motor 21 to rotate and dispense the medicine twice or even multiple times.

[0053] 5. Since the upper end of the stirring rod 5 is connected to the medicine bin cover 4 and the lower end is connected to the medicine feeding rotating plate 25, during the continuous medicine feeding process, the medicine feeding rotating plate 25 continues to swing, driving the stirring rod 25 to stir in the medicine bin 1, breaking the medicine bin arch and preventing arch formation;

[0054] 6. If the weighing sensor 32 detects that the weight of the weighing medicine bin 33 reaches the set value, the control system controls the medicine dispensing motor 21 to stop rotating and the medicine dispensing rotating plate 25 to close to ensure the internal sealing of the medicine bin 1;

[0055] 7. Then the weighing and dispensing device 31 is started to continuously dispense all the medicine in the weighing medicine bin 33 into the medicine barrel 7;

[0056] 8. After the drug delivery is completed, the weighing and dispensing device 31 stops working, and the dispensing rotating plate 25 at the bottom is reset and closed to prevent water vapor from entering the drug barrel 7;

[0057] 9. The water reserved in the medicine barrel 7 is mixed with the medicine that has fallen in to form a liquid medicine, which flows to the unit for the pigs to drink.

[0058] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
