Description

Technical Field

[0001] This utility model relates to the field of livestock breeding technology, specifically to an adjustable dosage feeder for paste-like traditional Chinese medicine suitable for cattle and sheep breeding. Background Technology

[0002] In the practice of administering medication to livestock such as cattle and sheep, oral administration is an important method. This typically involves multiple operators, divided into assistants and feeders. The assistants control the animal, while the feeder inserts the medication applicator through the animal's mouth into its esophagus and then pushes the applicator to administer the medication. During this process, the animal usually struggles violently, greatly consuming the operators' energy and increasing the risk of injury. This is especially true when the medication is a paste-like traditional Chinese medicine; due to its viscosity, the resistance to pushing the applicator is high, leading to a longer administration time and increased animal struggling time, further increasing the operators' energy expenditure and risk of injury. Utility Model Content

[0003] This invention provides an adjustable dosage feeder for paste-like traditional Chinese medicine suitable for cattle and sheep farming. It improves upon the problem of long feeding time when feeding livestock paste-like traditional Chinese medicine in the prior art, and can shorten the feeding time.

[0004] To achieve the above objectives, this utility model provides an adjustable dosage feeder for paste-like traditional Chinese medicine suitable for cattle and sheep farming, comprising:

[0005] The injection cartridge includes a connected drug storage section and an airtight section. The drug storage section has a piston that slides along the axial direction inside. The airtight section has an air inlet. The outer wall of the drug storage section has a guide rail that slides along the axial direction. A first position sensor is slidably disposed in the guide rail. The first position sensor is used to sense the position of the piston.

[0006] The pneumatic system includes a compressed air source and a valve assembly. The compressed air source is connected to the valve assembly, which is connected to the air inlet via a pipeline. The valve assembly is signal-connected to the first position sensor. In use, the first position sensor can be moved along the guide rail to the side of the piston near the airtight section and fixed. Then, medicine is loaded into the medicine storage section, which will cause the piston to slide towards the airtight section. Continue loading medicine until the piston reaches the first position sensor. At this time, the first position sensor sends a signal to the valve assembly, indicating that the piston has reached the top dead center and air can be introduced into the airtight section to push the piston to feed medicine. By adjusting the position of the first position sensor in the guide rail, the amount of medicine pushed out by the piston in a single operation, i.e., the amount of medicine fed in a single operation, can be adjusted. At this time, the operator can place the adjustable dosage medicine paste feeder suitable for cattle and sheep farming into the animal's mouth and manipulate the valve assembly to push the piston until all the medicine in the medicine storage section is discharged, thus completing the feeding. Because the piston is driven by compressed air, it has greater power and speed than manual pushing. When feeding medicine, especially when the medicine is a viscous paste, it can be completed in a shorter time, thereby shortening the time the livestock struggle and reducing the physical exertion and risk of injury to the operator.

[0007] As an optional technical solution, the airtight section is also provided with an air outlet, which is spaced apart from the air inlet;

[0008] The pneumatic system also includes a vacuum generator, the air inlet of which is connected to the valve assembly, and the vacuum end of which is connected to the air outlet. When the medicine is a paste-like traditional Chinese medicine, it is difficult to fill the storage section manually due to its high viscosity. This technical solution provides an adjustable dosage feeder for paste-like traditional Chinese medicine in cattle and sheep farming. By connecting the vacuum end of the vacuum generator to the airtight section, when medicine needs to be filled into the storage section, the operator can manipulate the valve assembly to supply air to the air inlet of the vacuum generator, creating a negative pressure in the vacuum section. This drives the piston to move towards the airtight section, allowing the storage section to extract medicine from the storage container, thus completing the filling process.

[0009] As an optional technical solution, a second position sensor is also included. The second position sensor is slidably disposed on the guide rail and spaced apart from the first position sensor. The second position sensor is located on the side of the piston away from the airtight section, and the first position sensor is located on the side of the piston close to the airtight section. The second position sensor is signal-connected to the valve assembly. The drug storage section of this technical solution can be filled with the medicine required for multiple feedings at once. In use, the first position sensor is moved to the position before the piston begins feeding, and the position of the second position sensor is determined according to the amount of medicine for a single feeding. After the piston moves from the first position sensor to the second position sensor, the second position sensor sends a signal to the valve assembly, and the valve assembly stops supplying air to the airtight section. The piston stops moving. The amount of medicine pushed out by the piston during this process is the single feeding amount in this technical solution. The single feeding amount can be adjusted by adjusting the distance between the second position sensor and the initial position of the piston. Continuous feeding can be achieved by continuously adjusting the position of the second position sensor. By moving the first position sensor, the position of the piston can be more accurately determined, which helps to avoid the piston moving unexpectedly during continuous medication, thus preventing the amount of medication dispensed per feeding from becoming unstable.

[0010] As an optional technical solution, there are two guide rails arranged in parallel, with the first position sensor and the second position sensor respectively located on different guide rails. Placing the first and second position sensors on different guide rails allows them to be closer together along the axial direction of the drug storage section without interfering with each other. This helps reduce the minimum single-use dosage of the piston, thus enabling this technical solution to accommodate drugs requiring smaller doses.

[0011] As an optional technical solution, the system also includes a pigment spray nozzle and a pigment container. The pigment container is detachably connected to the pigment spray nozzle, which is disposed on the outer wall of the injection cylinder and arranged parallel to the axial direction of the drug storage section. The pigment spray nozzle is connected to the valve assembly. The pigment spray nozzle can spray pigment onto livestock after drug administration to mark them, thereby distinguishing between livestock that have been given medication and those that have not. Furthermore, different colored pigments can be used to differentiate the frequency or type of medication administration.

[0012] As an optional technical solution, the airtight section also includes a pressure relief valve. The outlet of the pressure relief valve is connected to the pigment spray pipe, and the pigment tank is closer to the nozzle of the pigment spray pipe than the pressure relief valve. After the piston completes the feeding, it discharges all the medicine in the storage section and reaches its stroke limit. The compressed air source continues to inject gas into the airtight section, causing the pressure in the airtight section to rise until it reaches the threshold of the pressure relief valve. This allows the gas in the airtight section to be ejected through the pressure relief valve, carrying pigment, from the pigment spray pipe to mark the livestock that have been fed the medicine.

[0013] As an optional technical solution, a second position sensor is also included. The second position sensor is slidably disposed on the guide rail and spaced apart from the first position sensor. The second position sensor is located on the side of the piston away from the airtight section, and the first position sensor is located on the side of the piston close to the airtight section. The second position sensor is signal-connected to the valve assembly, and the second position sensor is used to connect the valve assembly to the pigment spray nozzle. In this technical solution, the drug storage section is filled with the medicine required for multiple feedings. Each time the piston completes a feeding, the piston will trigger the second position sensor. At this time, the second position sensor transmits a signal to the valve assembly, causing the valve assembly to cut off the air supply to the airtight section and supply air to the pigment spray nozzle, thereby spraying out pigment to mark the livestock that have been fed the medicine.

[0014] As an optional technical solution, the valve assembly includes a first solenoid valve and a second solenoid valve. The inlet of the first solenoid valve is connected to the compressed air source, one outlet of the first solenoid valve is connected to the pigment spray pipe, and the other is connected to the inlet of the second solenoid valve. The second position sensor signal is connected to the second solenoid valve. The outlet of the second solenoid valve is connected to the airtight section. The cooperation between the first and second solenoid valves facilitates the switching of the valve assembly between more states.

[0015] As an optional technical solution, the medicine storage section has a medicine hole on the side opposite to the airtight section. The adjustable dosage medicine feeder for cattle and sheep also includes a feeding tube connected to the medicine hole. In use, the feeding tube can be directly inserted into the animal's esophagus for medication, which helps to reduce medicine spillage caused by the animal struggling.

[0016] As an optional technical solution, the feeding tube is detachably connected to the medicine hole, and the inner diameter of the medicine hole is larger than the inner diameter of the feeding tube. When filling the medicine storage section, the feeding tube can be detached from the medicine hole, and the medicine in the medicine storage container can be drawn into the medicine storage section through the medicine hole. Since the inner diameter of the medicine hole is larger than that of the feeding tube, drawing medicine through the medicine hole helps to improve the efficiency of filling medicine.

[0017] One or more technical solutions provided by this utility model have at least the following technical effects or advantages:

[0018] This utility model provides an adjustable dosage feeder for paste-like traditional Chinese medicine suitable for cattle and sheep farming. It consists of an injection cylinder and a pneumatic system. The injection cylinder has a connected airtight section and a storage section. An axial piston is located inside the storage section, and an axial guide rail is located outside the storage section. A first position sensor is located inside the guide rail. The compressed air source of the pneumatic system is connected to the airtight section via a valve assembly. In use, medicine is filled into the storage section, and compressed air is supplied to the airtight section to push the piston, thus pushing the medicine out of the storage section. When the piston reaches the first position sensor, the sensor sends a signal to close the valve assembly, stopping the air supply and stopping the piston's movement, thereby completing the feeding. Because the piston is driven by compressed air, it has greater force and speed than manual pushing, allowing for faster feeding, reducing the time livestock struggle, and thus reducing the operator's physical exertion and risk of injury.

[0031] Example 1

[0032] This embodiment provides an adjustable dosage feeder for a paste-like traditional Chinese medicine suitable for cattle and sheep farming, including a dispensing cylinder 1 and a pneumatic system. The dispensing cylinder 1 includes a connected storage section 11 and an airtight section 12. A piston 111 is axially slidable inside the storage section 11. An air inlet 121 is provided on the airtight section 12. A guide rail 112 is axially mounted on the outer wall of the storage section 11, and a first position sensor 113 is slidably disposed within the guide rail 112. The first position sensor 113 is used to sense the position of the piston 111. The pneumatic system includes a compressed air source 21 and a valve assembly 22. The compressed air source 21 is connected to the valve assembly 22, and the valve assembly 22 is connected to the air inlet 121 via a pipeline. The valve assembly 22 is signal-connected to the first position sensor 113.

[0033] In use, the first position sensor 113 can be moved along the guide rail 112 to the side of the piston 111 near the airtight section 12 and fixed. Then, medicine is loaded into the medicine storage section 11, which will cause the piston 111 to slide toward the airtight section 12. Continue loading medicine until the piston 111 reaches the first position sensor 113. At this time, the first position sensor 113 sends a signal to the valve assembly 22, indicating that the piston 111 has reached the top dead center and air can be introduced into the airtight section 12 to push the piston 111 to feed medicine. By adjusting the position of the first position sensor 113 in the guide rail 112, the amount of medicine pushed out by the piston 111 in a single feeding can be adjusted. At this time, the operator can place the adjustable dosage medicine feeder for cattle and sheep into the mouth of the livestock and operate the valve assembly 22 to push the piston 111 until all the medicine in the medicine storage section 11 is discharged, thus completing the feeding. Since the piston 111 is driven by compressed air, it has greater power and speed than manual pushing. When feeding medicine, especially when the medicine is a viscous paste-like traditional Chinese medicine, it can be completed in a shorter time, thereby shortening the time the livestock struggles and reducing the physical exertion and risk of injury to the operator.

[0034] Preferably, the drug storage section 11 can be made of transparent plastic, glass, or other materials to allow operators to observe the interior of the drug storage section 11. Scales can be provided on the drug storage section 11 or the guide rail 112 to facilitate adjustment of the first position sensor 113 by the operator to determine the dosage. Furthermore, a transparent observation window can be provided axially on the outer wall of the drug storage section 11.

[0035] The first position sensor 113 can be a magnetic switch, or a photoelectric switch when the drug storage section 11 is made of transparent material.

[0036] As an optional implementation, the airtight section 12 is further provided with an air outlet 122, which is spaced apart from the air inlet 121;

[0037] The pneumatic system also includes a vacuum generator 23, whose inlet is connected to the valve assembly 22 and whose vacuum end is connected to the outlet 122. When the medicine is a paste-like traditional Chinese medicine, it is difficult to fill the medicine into the storage section 11 by manual suction due to its high viscosity. The adjustable dosage feeder for paste-like traditional Chinese medicine suitable for cattle and sheep breeding in this embodiment connects the vacuum end of the vacuum generator 23 to the airtight section 12. When it is necessary to fill the storage section 11 with medicine, the operator can operate the valve assembly 22 to supply air to the inlet of the vacuum generator 23, so that the vacuum section of the vacuum generator 23 generates negative pressure, thereby driving the piston 111 to move towards the airtight section 12, so that the storage section 11 can draw medicine from the medicine storage container, thus completing the medicine filling.

[0038] As an optional implementation, the system also includes a pigment spray nozzle 3 and a pigment container 31. The pigment container 31 is detachably connected to the pigment spray nozzle 3. The pigment spray nozzle 3 is disposed on the outer wall of the injection cylinder 1 and is arranged parallel to the axial direction of the drug storage section 11. The pigment spray nozzle 3 is connected to the valve assembly 22. The pigment spray nozzle 3 can spray pigment onto the livestock after the medicine has been administered to mark them, thereby distinguishing between livestock that have been given medicine and those that have not. Furthermore, different colors of pigment can be used to distinguish the frequency or type of medicine administered.

[0039] As an optional implementation, the medicine storage section 11 has a medicine hole 115 on the side opposite to the airtight section 12. The adjustable dosage medicine feeder for cattle and sheep also includes a feeding tube 13, which is connected to the medicine hole 115. In use, the feeding tube 13 can be directly inserted into the esophagus of the livestock for medication, which helps to reduce medicine spillage caused by the livestock struggling.

[0040] As an optional implementation, the feeding tube 13 is detachably connected to the medicine hole 115, the inner diameter of which is larger than the inner diameter of the feeding tube 13. When filling the medicine storage section 11, the feeding tube 13 can be detached from the medicine hole 115, and the medicine in the medicine storage container can be drawn into the medicine storage section 11 through the medicine hole 115. Since the inner diameter of the medicine hole 115 is larger than that of the feeding tube 13, drawing medicine through the medicine hole 115 helps to improve the efficiency of filling medicine.

[0041] Example 2

[0042] Based on Embodiment 1, the airtight section 12 further includes a pressure relief valve 123. The outlet of the pressure relief valve 123 is connected to the pigment spray pipe 3. The pigment tank 31 is closer to the nozzle of the pigment spray pipe 3 than the pressure relief valve 123. After the piston 111 completes the feeding, it discharges all the medicine in the medicine storage section 11 and reaches its stroke limit. The compressed air source 21 continues to inject gas into the airtight section 12, causing the pressure in the airtight section 12 to rise until it reaches the threshold of the pressure relief valve 123. This allows the gas in the airtight section 12 to be sprayed out of the pigment spray pipe 3 through the pressure relief valve 123, carrying the pigment, to mark the livestock that have been fed medicine.

[0043] It should be noted that this embodiment should be used when the drug storage section 11 is filled with the medicine required for one feeding at most, and the drug feeding piston 111 pushes out all the medicine in the drug storage section 11 each time.

[0044] Example 3

[0045] Based on Embodiment 1, this embodiment further includes a second position sensor 114. The second position sensor 114 is slidably disposed on the guide rail 112 and spaced apart from the first position sensor 113. The second position sensor 114 is disposed on the side of the piston 111 away from the airtight section 12, and the first position sensor 113 is disposed on the side of the piston 111 close to the airtight section 12. The second position sensor 114 is signal-connected to the valve assembly 22. In this embodiment, the drug storage section 11 can be filled with the medicine required for multiple feedings at once. In use, the first position sensor 113 is moved to the position where the piston 111 was before the start of drug feeding, and the position of the second position sensor 114 is determined according to the amount of medicine in a single feeding. After the piston 111 moves from the first position sensor 113 to the second position sensor 114, the second position sensor 114 sends a signal to the valve assembly 22, and the valve assembly 22 stops supplying air to the airtight section 12. The piston 111 stops moving. The amount of medicine pushed out by the piston 111 during this process is the amount of medicine fed in a single feeding in this embodiment. The amount of medicine fed in a single feeding can be adjusted by adjusting the distance between the second position sensor 114 and the initial position of the piston 111. Continuous drug feeding can be achieved by continuously adjusting the position of the second position sensor 114. By moving the first position sensor 113, the position of the piston 111 can be more accurately determined, which helps to avoid the piston 111 moving unexpectedly during continuous medication, thus preventing the amount of medication dispensed per feeding from becoming unstable.

[0046] The second position sensor 114 can be a magnetic switch, or a photoelectric switch when the drug storage section 11 is made of transparent material.

[0047] Optionally, the second position sensor 114 can be integrated into the first position sensor 113, and the first position sensor 113 can be set on the side of the piston 111 away from the airtight section 12, so that the adjustable dosage feeder for paste-like traditional Chinese medicine suitable for cattle and sheep breeding in this embodiment only controls the stop position of the piston 111 when feeding medicine, so as to reduce costs.

[0048] As an optional implementation, there are two guide rails 112 arranged in parallel, with the first position sensor 113 and the second position sensor 114 respectively located on different guide rails 112. Placing the first position sensor 113 and the second position sensor 114 on different guide rails 112 allows them to be closer together along the axial direction of the drug storage section 11 without interfering with each other. This helps reduce the minimum single-use dosage of the piston 111, thus enabling this embodiment to accommodate drugs requiring smaller doses.

[0049] As an optional implementation, the second position sensor 114 is also used to connect the valve assembly 22 to the pigment spray nozzle 3. In this embodiment, the drug storage section 11 is filled with the medicine required for multiple feedings. Each time the piston 111 completes a feeding, the piston 111 will trigger the second position sensor 114. At this time, the second position sensor 114 transmits a signal to the valve assembly 22, causing the valve assembly 22 to cut off the air supply to the airtight section 12 and supply air to the pigment spray nozzle 3, thereby spraying out pigment to mark the livestock that have been fed medicine.

[0050] As an optional implementation, the valve assembly 22 includes a first solenoid valve 221 and a second solenoid valve 222. The inlet of the first solenoid valve 221 is connected to the compressed air source 21, one outlet of the first solenoid valve 221 is connected to the pigment spray pipe 3, and the other is connected to the inlet of the second solenoid valve 222. The second position sensor 114 is signal-connected to the second solenoid valve 222. The outlet of the second solenoid valve 222 is connected to the airtight section 12. The cooperation between the first solenoid valve 221 and the second solenoid valve 222 facilitates the switching of the valve assembly 22 between more states.

[0051] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
