Description

Technical Field

[0001] This utility model belongs to the technical field of pig farming, and in particular relates to a fully automatic precision dosing device. Background Technology

[0002] In the pig farming industry, medication is needed for prevention and treatment of pigs to ensure their health and prevent death from illness. Among the various methods of medication administration, common methods include manual administration, injection, and drinking water administration. Manual administration poses a risk of cross-contamination due to frequent contact between the worker and the medication surface; injection involves personnel contact with the pigs, and inadequate needle disinfection can lead to further disease transmission; while drinking water administration automatically delivers medication to the pigs' feed troughs via pipelines, requiring minimal human intervention, and the system is fully automated, simple, convenient, and saves time and effort.

[0003] Currently, although automatic dosing devices are used for administering medication through drinking water, personnel still need to weigh the corresponding medication daily according to the dosage and add it to the dosing device. This is cumbersome, and personnel may make mistakes in weighing the medication. If too little medication is weighed, the concentration will be low and there will be no therapeutic effect. If too much medication is weighed, the concentration will be too high, which may lead to poisoning of the pig herd in severe cases.

[0004] Therefore, how to solve the above problems has become a key research topic in the existing technology field. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a fully automatic precision dosing device, which solves the above problems.

[0006] To achieve the above objectives, this utility model discloses a fully automatic precision dosing device, comprising:

[0007] At least two medicine compartments are provided for temporary storage of medicines, and a medicine dispensing device is provided at the bottom of each medicine compartment.

[0008] A medicine dispensing device is used to control the dispensing of medicine from the medicine bin. The medicine dispensing device includes a dispensing motor, a dispensing impeller, a unidirectional rotor, and a rotating shaft. The dispensing motor is connected to the rotating shaft. At least two unidirectional rotors are provided on the rotating shaft. The unidirectional rotors are provided with the dispensing impellers. The dispensing impellers are located below the dispensing port of the medicine bin, and each dispensing impeller corresponds to a specific medicine bin. A portion of the unidirectional rotors engages with the rotating shaft when the shaft rotates in the forward direction, and another portion of the unidirectional rotors engages with the rotating shaft when the shaft rotates in the reverse direction.

[0009] The drug dispensing impeller includes a rotating disk and blades. The rotating disk is provided with uniformly distributed blades, such that the blades are spaced apart by a space to form multiple cavities of equal volume.

[0010] Compared with existing technologies, this application has the following advantages: First, different drugs are stored in different drug compartments. Based on the type of pig herd and the intake amount of different drugs, when medication is needed, the dispensing motor is controlled to rotate in both directions. This drives a unidirectional rotor meshing with the shaft to rotate, which in turn drives the dispensing impeller to rotate. The dispensing impeller rotates at a certain angle, and the corresponding drug in the compartment rotates with the cavity. When the cavity rotates to the point where the opening faces downwards, the drug falls to the designated position due to its own weight. Because the volume of the cavities is equal, the weight of drug contained in each cavity is the same. Different rotation angles are set according to the density of different drugs. When the rotation angle of the dispensing impeller meets the set value, the dispensing motor is stopped, meaning the amount of medication dispensed meets the requirements, achieving precise drug administration. It should be noted that because some unidirectional rotors mesh with the shaft when it rotates in the forward direction, and others mesh with the shaft when it rotates in the reverse direction, the dispensing motor can be rotated in both directions to dispense two different drugs separately, depending on the actual required medication.

[0011] Therefore, this design can control the administration of two drugs by using a single dispensing motor that rotates forward and backward, thus saving costs. During drug administration, no manual dispensing is required, which not only reduces the risk of cross-infection caused by manual handling of drugs, but also enables automatic and accurate drug administration, avoiding problems caused by over- or under-dosing.

[0012] Furthermore, there are two drug chambers, two unidirectional rotors, and two drug dispensing impellers, with the two drug chambers sharing one drug dispensing motor for drug dispensing control.

[0013] Furthermore, the rotating shaft includes a rotating shaft and a rotating shaft disc disposed on the rotating shaft. The rotating shaft is connected to the dispensing motor. The rotating shaft disc has two helical teeth on each side in opposite directions. The rotor disc of the unidirectional rotor has helical teeth in the opposite direction to those on the rotating shaft disc. The unidirectional rotors are respectively disposed on both sides of the rotating shaft disc. When the rotating shaft disc rotates, the rotor disc on one side meshes with the rotating shaft disc, thereby driving the dispensing impeller to rotate, realizing the dispensing of medicine from the medicine chamber on that side. The rotor disc on the other side does not mesh with the rotating shaft disc.

[0014] Furthermore, the top of the medicine compartment is provided with a medicine compartment cover, the inside of which is equipped with a sealing gasket, and its exterior is detachably connected to the medicine compartment.

[0015] Furthermore, the medicine compartment is equipped with a stirring device to prevent the medicine from caking.

[0016] Furthermore, the stirring device includes a stirring rod, a stirring motor, and a flexible spring. The two ends of the stirring motor are respectively connected to the stirring rod, and the flexible spring is provided on the stirring rod.

[0017] Furthermore, the stirring rod has a smooth surface, a circular shape, and a mixing support in the middle.

[0018] Furthermore, each of the stirring rods is equipped with four flexible springs, two of which are oriented upwards and two of which are oriented downwards.

[0019] Furthermore, the lower part of the drug-dispensing impeller is provided with a drug-dispensing cylinder, the bottom of which is an arc-shaped opening with a gap in the middle.

[0020] Furthermore, it also includes a control system, which is electrically connected to the drug dispensing motor. The control system controls the rotation angle of the drug dispensing motor according to the density of different drugs and uploads the drug data to the cloud platform. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-3 As shown, this utility model discloses a fully automatic precision dosing device, comprising:

[0031] At least two medicine compartments 1 are used for temporary storage of medicines, and a medicine dispensing device 2 is provided at the bottom of the medicine compartment 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 dispensing motor 21, a dispensing impeller 22, a one-way rotor 23, and a rotating shaft 24. The dispensing motor 21 is connected to the rotating shaft 24. At least two one-way rotors 23 are provided on the rotating shaft 24. The one-way rotors 23 are provided with dispensing impellers 22. The dispensing impellers 22 are located below the dispensing port of the medicine bin 1, and the dispensing impellers 22 correspond one-to-one with the medicine bin 1. Among them, a part of the one-way rotors 23 meshes with the rotating shaft 24 when the rotating shaft 24 rotates in the forward direction, and the other part of the one-way rotors 23 meshes with the rotating shaft 24 when the rotating shaft 24 rotates in the reverse direction.

[0033] The drug dispensing impeller 22 includes a turntable and blades. The turntable has evenly distributed blades, which form multiple cavities 25 with equal volume by spacing between the blades. When the drug dispensing impeller 22 rotates, the drug can fall into each cavity 25 one by one. Since a drug chamber 1 contains the same drug with equal density and volume, it can ensure that the weight of the drug in each cavity 25 is consistent.

[0034] Compared with the prior art, this application has the following advantages: Different drugs are first stored in different drug compartments 1. Based on the type of pig herd and the intake amount of different drugs, when medication is needed, the dispensing motor 21 is controlled to rotate in both directions. This drives the unidirectional rotor 23, which meshes with the shaft 24, to rotate. The unidirectional rotor 23 then drives the dispensing impeller 22 to rotate, causing it to rotate at a certain angle. Correspondingly, the medication in the drug compartment 1 rotates with the cavity 25. When the cavity 25 rotates to an opening facing downwards, the medication falls to the designated position due to its own weight. Since the volumes of the cavities 25 are equal... Therefore, the weight of the drug contained in each cavity 25 is the same. Different rotation angles are set according to the density of different drugs. When the rotation angle of the dispensing impeller 22 meets the set value, the dispensing motor 21 is controlled to stop, that is, the amount of drug dispensed meets the requirements and the drug is dispensed accurately. It should be noted that because a part of the unidirectional rotor 23 meshes with the rotating shaft 24 when the rotating shaft 24 rotates in the forward direction, and another part of the unidirectional rotor 23 meshes with the rotating shaft 24 when the rotating shaft 24 rotates in the reverse direction, the dispensing motor 21 can be rotated in both directions according to the actual required drug to achieve the dispensing of two drugs separately.

[0035] Therefore, this design can control the administration of two drugs by using a single dispensing motor 21 to rotate forward and backward, thus saving costs. During drug administration, there is no need for manual addition, which not only reduces the risk of cross-infection caused by manual handling of drugs, but also enables automatic and accurate drug administration, avoiding problems caused by over- or under-dosing.

[0036] Following the above embodiments, more specifically, in one embodiment, there are two medicine bins 1, two unidirectional rotors 23, and two dispensing impellers 22. The two medicine bins 1 share a single dispensing motor 21 to control the dispensing. Each medicine bin 1 can store one type of medicine, and the dispensing of two medicines can be achieved by rotating the dispensing motor 21 in both directions. This not only saves costs, but the design of two medicine bins 1 can also meet the medication needs of piglets for two weeks.

[0037] Following the above embodiments, more specifically, as Figure 2-4 As shown, the rotating shaft 24 includes a rotating shaft 26 and a rotating shaft disc 27 disposed on the rotating shaft 26. The rotating shaft 26 is connected to the drug dispensing motor 21. The rotating shaft disc 27 has two helical teeth 29 in opposite directions on each side. The rotor disc 28 of the unidirectional rotor 23 has helical teeth 29 in the opposite direction to the rotating shaft disc. The unidirectional rotors 23 are respectively disposed on both sides of the rotating shaft disc 27. When the rotating shaft disc 27 rotates, the rotor disc 28 on one side meshes with the rotating shaft disc 27, thereby driving the drug dispensing impeller 22 to rotate, realizing the drug dispensing of the drug chamber 1 on that side. The rotor disc 28 on the other side does not mesh with the rotating shaft disc 27.

[0038] When the dispensing motor 21 rotates in the forward direction, it drives the rotating shaft 24 to rotate. The one-way rotor 23 on the side meshing with the rotating shaft 24 rotates accordingly, driving the dispensing impeller 22 to rotate. The medicine in the cavity 25 of the dispensing impeller 22 can follow the rotation angle and fall from top to bottom, and the weight of the medicine falling each time is consistent, thereby controlling the rotation angle of the dispensing motor 21 to achieve precise dispensing. The one-way rotor 23 on the other side, which does not mesh with the rotating shaft 24, will slip, that is, it will not follow the rotation. This allows the dispensing motor 21 to rotate in the forward direction, dispensing medicine in one medicine chamber 1. When it rotates in the reverse direction, dispensing medicine in the other medicine chamber 1, and dispensing medicine independently without interfering with each other. It is worth mentioning that with this structure, only one dispensing motor 21 is needed to meet the requirements, saving the cost of one dispensing motor 21.

[0039] Following the above embodiments, more preferably, in order to prevent moisture from entering the medicine compartment 1, the top of the medicine compartment 1 is provided with a medicine compartment cover 3. The medicine compartment cover 3 is equipped with a sealing gasket inside, and its exterior is detachably connected to the medicine compartment 1 to ensure a tight seal. In one embodiment, the medicine compartment cover 3 and the medicine compartment 1 are connected by a snap fastener.

[0040] Following the above embodiment, more specifically, the medicine compartment 1 is equipped with a stirring device 4 to prevent the medicine from caking. The stirring device 4 can solve the problem of poor dispensing caused by the caking of the medicine.

[0041] Following the above embodiments, more specifically, as Figure 5 As shown, the stirring device 4 includes a stirring rod 41, a stirring motor 42, and a flexible spring 43. The two ends of the stirring motor 42 are connected to the stirring rod 41, and the flexible spring 43 is installed on the stirring rod 41. The flexible spring 43 is designed to have a telescopic function, which can reduce the collision force with the side wall and realize the internal space disturbance of the medicine container 1, so as to solve the problem of arching inside the medicine container 1.

[0042] It should be noted that the motor shaft of the stirring motor 42 is a through-shaft structure, with two stirring rods 41 connected to both ends of the motor shaft, driving the two stirring rods 41 to move and achieve the purpose of breaking up the arch. When the stirring motor 42 rotates, the stirring rods 41 will follow and make a circular stirring motion, and the flexible spring 43 will also rotate at the same time, so that there is a composite disturbance in the medicine tank 1, including lateral and longitudinal disturbances. This can fully stir the temporarily stored medicine and prevent the medicine from clumping or arching. At the same time, this stirring and arch-breaking structure only uses one stirring motor 42 to achieve the arch-breaking effect of two medicine tanks 1, saving the cost of one stirring motor 42.

[0043] Following the above embodiment, more specifically, in order to prevent the medicine from sticking to the stirring rod 41, the stirring rod 41 has a smooth surface, a circular shape, and a mixing support 44 in the middle.

[0044] Following the above embodiment, more specifically, four flexible springs 43 are installed on each stirring rod 41, with two flexible springs 43 pointing upwards and two flexible springs 43 pointing downwards. This design can expand the disturbance range of the stirring rod 41.

[0045] Following the above embodiment, more specifically, a dispensing cylinder 5 is provided at the lower part of the dispensing impeller 22. The bottom of the dispensing cylinder 5 is an arc-shaped opening with a gap in the middle. A mixing tank 6 is provided at the lower part of the dispensing cylinder 5 to receive the falling medication. The mixing tank 6 contains water to mix with the medication. The arc-shaped opening at the bottom of the dispensing cylinder 5 and its completely smooth interior ensure smooth dispensing. The gap in the middle of the arc-shaped opening allows water vapor to flow upwards, preventing water vapor from completely entering the dispensing cylinder 5 and thus avoiding wetting the dispensing cylinder 5 and affecting the dispensing process.

[0046] Following the above embodiments, more specifically, it also includes a control system. The control system is electrically connected to the dispensing motor 21. The control system controls the rotation angle of the dispensing motor 21 according to the density of different drugs and uploads the drug data to the cloud platform. Through the design of the control system, the equipment can be automatically controlled, eliminating behaviors such as under-dispensing, over-dispensing, no dispensing, missed dispensing, and random dispensing. The entire process is traceable, accurately recording and reporting drug dispensing information, effectively ensuring the treatment effect.

[0047] The workflow for this application is as follows:

[0048] 1. Users can add one or two medications according to their medication needs. They can open the medicine compartment cover 3 and add the medication to the medicine compartment 1 at once.

[0049] 2. Based on the type of pig herd and the intake of different drugs, the system automatically controls the drug dispensing motor 21 to rotate forward or backward, driving the rotating shaft 24 to rotate and mesh with the unidirectional rotor 23. The drug dispensing impeller 22 rotates at a certain angle, and the temporarily stored drugs on one side rotate with the cavity 25 and automatically fall into the mixing tank 6 along the drug dispensing cylinder 5.

[0050] 3. During the drug dispensing process, the system will start the stirring motor 42 to make the stirring rod 41 and the flexible spring 43 rotate, break the arch in the drug chamber 1, prevent the drug from clumping and arching, and prevent the drug from falling into the cavity 25 of the drug dispensing impeller 22.

[0051] 4. The system sets different rotation angles according to the density of different drugs. When the rotation angle of the drug-dispensing impeller 22 is satisfied, the drug-dispensing motor 21 is controlled to stop, that is, the amount of drug dispensed meets the requirements.

[0052] 5. The water reserved in the mixing tank 6 is mixed with the falling medicine to form a medicine solution, which flows to the unit for the pigs to drink.

[0053] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those 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 to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
