Description

Technical Field

[0001] The present invention relates to the technical field of gastric juice extraction equipment, and specifically to an electric sheep rumen gastric juice extraction equipment. Background Art

[0002] As disclosed in the Chinese patent with the publication number CN213821504U, which discloses a sheep rumen gastric juice collection device, belonging to the technical field of animal science experiments, including: a manual negative pressure device, a collection bottle, and a gastric juice outlet tube; the suction port of the manual negative pressure device and one end of the gastric juice outlet tube are both connected to the collection bottle, and the other end of the gastric juice outlet tube is used to extend into the sheep rumen through the sheep's mouth.

[0003] However, the above solution has the following deficiencies: in the above patent, the gastric juice outlet tube is inserted into the sheep's stomach, and the gastric juice in the sheep rumen is pumped into the collection bottle through the manual negative pressure device. However, during the use process, since the composition of the rumen gastric juice usually includes food residues, microorganisms, digestive juices, etc., if the sheep has eaten or is digesting food, the rumen gastric juice may show different layers. At this time, it may cause the liquid pumped into the outlet tube to be a mixture of gastric juice and food residues, resulting in blockage of the outlet tube and preventing the rumen gastric juice from being pumped into the collection bottle. Therefore, we introduce an electric sheep rumen gastric juice extraction equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide an electric sheep rumen gastric juice extraction equipment to solve the problems raised in the above background art.

[0013] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figure 1-8 , the present invention provides a technical solution: Embodiment 1: An electric extraction device for sheep rumen fluid, comprising a collection bottle 1 and a sample collection tube 6. The upper end of the collection bottle 1 is movably installed with a bottle cap 29 through a buckle. By opening the buckle, the bottle cap 29 can be removed from the upper end of the collection bottle 1, so that the extracted gastric fluid in the collection bottle 1 can be poured out and the collection bottle 1 can be cleaned. After the operation is completed, the bottle cap 29 can be reinstalled to the upper end of the collection bottle 1 through the buckle. Inside the bottle cap 29, a first connecting pipe 2 and a second connecting pipe 3 are fixedly installed respectively. The length of the first connecting pipe 2 is greater than that of the second connecting pipe 3. The lower ends of the first connecting pipe 2 and the second connecting pipe 3 both extend into the collection bottle 1. The lower end of the second connecting pipe 3 is fixedly connected with a first one-way valve 31. Through the setting of the first one-way valve 31, the gas in the collection bottle 1 can enter the second connecting pipe 3, and the air in the second connecting pipe 3 will not enter the collection bottle 1; The upper ends of the first connecting pipe 2 and the second connecting pipe 3 both extend into the external environment and are fixedly connected with a three-way valve 8. In actual use, the three-way valve 8 should be a valve with a switch adjustment function. By adjusting the switch, the two connection ports in the three-way valve 8 can be connected. A gas guide pipe 9 is fixedly connected between the two three-way valves 8. The upper ends of the two three-way valves 8 are respectively fixedly connected with a liquid extraction hose 16. The end of the left liquid extraction hose 16 away from the three-way valve 8 is connected with a liquid extraction filtering mechanism, and the end of the right liquid extraction hose 16 away from the three-way valve 8 is connected with an extraction mechanism. When the upper and lower ends of the left three-way valve 8 are opened, the first connecting pipe 2 is connected with the liquid extraction hose 16 at this time. When the upper and lower ends of the right three-way valve 8 are opened, the second connecting pipe 3 is connected with the right liquid extraction hose 16 at this time. When the opposite ends and the upper ends of the two three-way valves 8 are opened, the left and right liquid extraction hoses 16 are connected with the gas guide pipe 9 at this time. By generating suction through the extraction mechanism, the gastric fluid enters the left liquid extraction hose 16 through the liquid extraction filtering mechanism and finally enters the collection bottle 1 for collection; A connection mechanism is provided inside the lower end of the collection bottle 1. The upper end of the sample collection tube 6 is screwed with a screw cap 5. When a small dose of gastric fluid needs to be taken for experimental use, the screw cap 5 is opened at this time and the sample collection tube 6 is screwed into the connection mechanism, so that the collection bottle 1 is connected with the sample collection tube 6 through the connection mechanism, and the gastric fluid in the collection bottle 1 enters the sample collection tube 6. After the sample collection tube 6 finishes collecting the gastric fluid, the sample collection tube 6 storing the gastric fluid is screwed off at this time, and the screw cap 5 is screwed back onto the upper end of the sample collection tube 6 again.

[0015] Example 2: Based on Embodiment 1, in order to enable the liquid extraction and filtration mechanism to be arranged above the gastric juice, the liquid extraction and filtration mechanism includes a circular box 22. A first cross-shaped sliding groove 21 is provided on the outer side of the circular box 22. A movable pipe 17 is movably connected in the first cross-shaped sliding groove 21. Two annular connecting plates 25 are fixedly connected to the inner side of the circular box 22. Sliding grooves 30 are provided on the opposite surfaces of the two annular connecting plates 25. A retaining ring 24 is slidably connected between the two sliding grooves 30. The movable pipe 17 is fixedly connected to the retaining ring 24. The upper end of the movable pipe 17 extends between the two annular connecting plates 25. The retaining ring 24 blocks between the two annular connecting plates 25, so that the gastric juice in the movable pipe 17 will not flow out when entering the inner sides of the two annular connecting plates 25; Sliding blocks 20 are fixedly connected to both sides of the movable pipe 17. The sliding blocks 20 are slidably connected in the first cross-shaped sliding groove 21. When the movable pipe 17 rotates, the sliding blocks 20 will move along the first cross-shaped sliding groove 21. A counterweight box 19 is fixedly connected to the lower end of the movable pipe 17. A filter plate 18 is fixedly connected to the lower end of the counterweight box 19. One end of the left liquid extraction hose 16 passes through the circular box 22 and extends into the inner side of one annular connecting plate 25. Floating blocks 23 are fixedly connected to both ends of the circular box 22. The material of the floating blocks 23 can be selected as a corrosion-resistant and lightweight material, such as polytetrafluoroethylene. Under the buoyancy of the two floating blocks 23, the circular box 22 will float on the surface of the gastric juice. At the same time, under the gravity of the counterweight box 19, the counterweight box 19 will pull the movable pipe 17 to rotate, so that the counterweight box 19 is always located in the gastric juice. When the movable pipe 17 rotates, the retaining ring 24 will move along the sliding groove 30; The extraction mechanism includes a connection box 14. One end of the right extraction hose 16 is fixedly connected to the connection box 14. A sealing slide plate 11 is slidably connected inside the connection box 14. One end of the connection box 14 away from the extraction hose 16 is movably connected to a T-shaped push rod 13. One end of the T-shaped push rod 13 is fixedly connected to the sealing slide plate 11. A return spring 12 is sleeved outside the T-shaped push rod 13. One end of the return spring 12 is fixedly connected to the sealing slide plate 11, and the other end is fixedly connected to the connection box 14. A second one-way valve 10 is fixedly connected inside one end of the connection box 14. One end of the second one-way valve 10 is fixedly connected to a valve 15. By pulling the T-shaped push rod 13 to move, the sealing slide plate 11 is driven to move. When the sealing slide plate 11 moves, suction will be generated inside the connection box 14, and at the same time, the return spring 12 is compressed. At this time, the gastric juice in the sheep's rumen is sucked into the counterweight box 19 when the sealing slide plate 11 moves. The gastric juice entering the counterweight box 19 will be filtered by a filter plate 18. The gastric juice then enters the annular connecting plate 25 through a movable tube 17, and finally enters the collection bottle 1 through the extraction hose 16 and the first connecting tube 2 for storage. Since the first connecting tube 2 and the second connecting tube 3 are arranged at different heights, when the gastric juice enters the collection bottle 1 through the first connecting tube 2, the gastric juice will not enter the second connecting tube 3. At the same time, under the setting of the first one-way valve 31, when no gastric juice is extracted and enters the collection bottle 1 once, when the operator continuously pulls the T-shaped push rod 13, the gas inside the connection box 14 will be discharged to the outside through the second one-way valve 10 and the valve 15, thereby realizing the continuous extraction of gastric juice; The connection mechanism includes a connection cavity 27. The connection cavity 27 is opened at the lower end of the collection bottle 1. Internal threads 26 are opened inside the connection cavity 27. A liquid guide tube 4 is slidably connected inside the connection cavity 27. Liquid inlet grooves 7 are opened on both sides of the liquid guide tube 4. The liquid inlet grooves 7 are opened on the left and right sides of the liquid guide tube 4. Through the liquid inlet grooves 7, the liquid guide tube 4 is connected to the inside of the collection bottle 1. The gastric juice in the collection bottle 1 will enter the sample collection tube 6 through the liquid guide tube 4 for storage; A connection spring 28 is sleeved outside the liquid guide tube 4. One end of the connection spring 28 is fixedly connected to the liquid guide tube 4, and the other end is fixedly connected to the connection cavity 27. The upper end of the sample collection tube 6 is screwed to the internal threads 26 inside the connection cavity 27. At this time, as the sample collection tube 6 continuously moves upward, the liquid guide tube moves upward. Through the liquid inlet grooves 7, the liquid guide tube 4 is connected to the inside of the collection bottle 1. The gastric juice in the collection bottle 1 will enter the sample collection tube 6 through the liquid guide tube 4 for storage.

[0016] Working principle: During use, the circular box 22 and the liquid extraction hose 16 are sent into the rumen of a sheep. Under the buoyancy of the two floating blocks 23, the circular box 22 will float on the surface of the gastric juice. At the same time, under the gravity of the counterweight box 19, the counterweight box 19 will pull the movable tube 17 to rotate, so that the counterweight box 19 is always located in the gastric juice. By pulling the T-shaped push rod 13 to move, the sealing slide plate 11 is driven to move. When the sealing slide plate 11 moves, the return spring 12 is compressed. At this time, the gastric juice in the rumen of the sheep is sucked into the counterweight box 19 when the sealing slide plate 11 moves. The gastric juice entering the counterweight box 19 will be filtered by the filter plate 18, and then the gastric juice passes through the movable tube 17 into the annular connecting plate 25, and finally enters the collection bottle 1 through the liquid extraction hose 16 and the first connecting tube 2 for storage; When the pushing of the T-shaped push rod 13 is released, at this time, under the elastic force of the return spring 12, the sealing slide plate 11 will return to the initial position. At the same time, the air entering the connecting box 14 will be discharged into the external environment through the second one-way valve 10. When the T-shaped push rod 13 is pulled outwards again, at this time, the sealing slide plate 11 will move again, so that the gastric juice is pumped into the collection bottle 1. When the filter plate 18 is blocked, at this time, the operator will encounter resistance when pulling the T-shaped push rod 13. At this time, the valve 15 is closed and the two three-way valves 8 are opened, so that the air guide tubes 9 are respectively connected to the two liquid extraction hoses 16. At this time, the pulling of the T-shaped push rod 13 is released, and the sealing slide plate 11 moves to send the gas into the air guide tube 9 and finally discharges from the counterweight box 19, so that the impurities blocked in the filter plate 18 are blown away to solve the blockage problem of the filter plate 18; When a small dose of gastric juice needs to be taken for experimental use, at this time, the screw cap 5 is opened, and the upper end of the sample collection tube 6 is screwed to the internal thread 26 in the connection cavity 27. At this time, as the sample collection tube 6 moves upward continuously, the liquid guide tube 4 will move upward along the connection cavity 27, and the liquid guide tube 4 is communicated with the inside of the collection bottle 1 through the liquid inlet groove 7. The gastric juice in the collection bottle 1 will enter the sample collection tube 6 through the liquid guide tube 4 for storage. After the storage is completed, the sample collection tube 6 is unscrewed, and the screw cap 5 is screwed back on the upper end of the sample collection tube 6 again.
