Technical Field
[0001] The utility model relates to the technical field of rumen methane emission of ruminants, and more specifically to a novel feeding type rumen methane detection device for ruminants. Background Art
[0002] The fed ruminant rumen methane detection device is a device used to monitor the methane gas emissions produced by ruminants (such as cattle, sheep, etc.) during the rumination process. The main function of this device is to help agricultural producers monitor the methane emissions produced by ruminants, so as to better understand and manage the impact of animal husbandry on the environment and take corresponding measures to reduce methane emissions. This is of great significance for reducing greenhouse gas emissions and improving animal husbandry production efficiency.
[0003] At present, the main means to accurately measure rumen methane emissions and gastrointestinal methane emissions of ruminants are sulfur hexafluoride (SF6) tracer technology, open or semi-open respiratory calorimetry systems, micrometeorological technology, and mathematical prediction model methods. Among them, sulfur hexafluoride (SF6) tracer technology is an accurate, fast, convenient and easy-to-use measurement method. It is suitable for the determination of CH4 emissions from ruminants under confinement, semi-confinement and grazing conditions. For sulfur hexafluoride (SF6) tracer technology, its core link is the preparation of permeation tubes. In the existing technology, brass materials are often used to make metal tubes with a nut on the top and a cylindrical bottom.
[0004] However, the commonly used SF6 permeation tube is made of brass. Although it can resist the corrosion of the strong acid environment (pH=6.0-7.0) to a certain extent and obtain more accurate measurement results, due to the unique physiological characteristics of ruminants, the chyme in the rumen is in continuous rumination, peristalsis and emptying activities. Therefore, the permeation tube is easy to cause damage to the internal organs of the rumen, posing a great safety hazard. Secondly, through the design of the nut, it needs to be tightened and fixed by using tools such as wrenches, and the operation is relatively cumbersome. For this reason, we propose a new feeding type rumen methane detection device for ruminants to solve the above problems. Utility Model Content

[0012] Technical effects and advantages of the utility model:
[0013] 1. The utility model is provided with a protective shell, which effectively solves the potential harm to the animal group caused by the material and appearance when the device is used, and at the same time protects the penetration tube, so as to improve the accuracy of the detection result.

[0024] In the embodiment of the present application, since the chyme in the rumen of the ruminant is in continuous rumination and peristaltic emptying activities, the commonly used permeation tube will cause damage to the rumen in the ruminant. After the protective shell 1 is set, the material of the protective shell 1 is set to PVC material, which effectively solves the potential harm to the animal group due to the material and appearance. Secondly, the air holes 2 are set at both ends of the shell of the protective shell 1 to ensure that the SF6 in the permeation tube body 31 can penetrate into the rumen of the ruminant, and finally complete the operation of the SF6 tracing technology. The device The invention is a device suitable for the SF6 method to measure the rumen methane of ruminants. When in use, SF6 is used as a tracer gas. First, the permeation tube body 31 is immersed in liquid nitrogen. After 15-20 seconds, the SF6 gas is quickly injected into the permeation tube body 31 using a syringe. Due to the low temperature of the liquid nitrogen, the gaseous SF6 is quickly converted into a solid state and stored in the permeation tube body 31. Then, the plug 35 is inserted into the open end of the permeation tube body 31, and the sealing strip 37 is inserted into the sealing slot 34 for sealing. The first magnetic attraction layer 36 and the second magnetic attraction layer 38 attract each other, so that it is convenient to firmly insert the plug 35 into the open end of the permeation tube body 31 to seal it. The operation is convenient and the sealing effect is good. Then the permeation tube 3 is inserted into the protective shell 1. During the insertion process, the arc head 32 first contacts the top of the arc clamping block 4. When the permeation tube 3 is inserted downward, the permeation tube 3 moves downward to squeeze the arc clamping block 4 to both sides, thereby squeezing the spring 51. At this time, the spring 51 is in a compressed state. When the permeation tube 3 moves down to the middle, the spring 51 Under the rebound force, the two arc-shaped clamping blocks 4 will be pushed to move relatively toward the middle, so that the arc-shaped clamping blocks 4 are stuck in the clamping groove 33, thereby completing the fixation of the permeation tube 3. The operation is convenient and the fixation is more firm. Then it is placed in a biochemical incubator for anaerobic culture at 39°C for 2-3 months and then fed for use. The SF6 in the permeation tube body 31 and the methane gas produced by the rumen fermentation of ruminants are collected synchronously, and the concentrations of the two are detected by a gas chromatograph to obtain the methane production of ruminants, thereby completing the operation of ruminant rumen methane detection.
[0025] Furthermore, a sealing slot 34 is provided at the open end of the infiltration tube body 31, and a first magnetic layer 36 is fixedly connected to the open end of the infiltration tube body 31.

The sealing slot 34 and the sealing strip 37 are both arranged in a ring shape, and the sealing strip 37 is adapted to the sealing slot 34. A magnetic attraction force that attracts each other is arranged between the first magnetic layer 36 and the second magnetic layer 38. The plug 35 is adapted to the open end of the infiltration tube body 31. When in use, the sealing strip 37 is inserted into the sealing slot 34 for sealing, and the first magnetic layer 36 and the second magnetic layer 38 are attracted to each other, so that the plug 35 is conveniently inserted into the open end of the infiltration tube body 31 to seal it. The operation is convenient and the sealing effect is good.
[0026] Furthermore, the clamping assembly 5 includes a spring 51 fixedly connected to one side of the arc-shaped clamping block 4, the arc-shaped clamping block 4 is fixedly connected to a first limiting rod 52 on the same side of the spring 51, the other end of the spring 51 is fixedly connected to the inner wall of the protective shell 1, the inner wall of the protective shell 1 is fixedly connected to a second limiting rod 53 on the same side of the spring 51, the spring 51 is sleeved on the first limiting rod 52 and the second limiting rod 53, when in use, when the permeation tube 3 is inserted downward, the permeation tube 3 moves downward and squeezes the arc-shaped clamping block 4 to both sides, thereby squeezing the spring 51, at this time, the spring 51 is in a compressed state, when the permeation tube 3 moves down to the middle, the rebound force of the spring 51 will push the two arc-shaped clamping blocks 4 to move relative to the middle, so that the arc-shaped clamping block 4 is stuck in the card slot 33, thereby completing the fixation of the permeation tube 3, the operation is convenient, and the fixation is more firm.
[0027] Furthermore, air holes 2 are symmetrically provided at both ends of the protective shell 1. The shape of the protective shell 1 is set to be a hollow structure with hemispherical ends and a cylindrical middle section. When in use, the SF6 in the permeation tube 3 can be evenly penetrated through the provided air holes 2. The hollow structure of the protective shell 1 can effectively buffer the pressure and protect the permeation tube 3 from being affected, thereby improving the use efficiency of the permeation tube 3.
[0028] Furthermore, the permeation tube body 31 is an aluminum tube body, and the permeation tube body 31 is plugged into the arc-shaped clamp block 4. When in use, the aluminum tube body is not only acid-resistant but also lightweight, and can further protect the rumen of ruminants from damage.
[0029] The working principle of the utility model: when in use, since the chyme in the rumen of the ruminant is in continuous rumination and peristaltic emptying activities, the commonly used permeation tube in the rumen of the ruminant will cause damage to the rumen. After the protective shell 1 is set, the material of the protective shell 1 is set to PVC material, which effectively solves the potential harm to the animal group due to the material and appearance. Secondly, through the air holes 2 set at both ends of the shell of the protective shell 1, it is ensured that the SF6 in the tube body 31 of the permeation tube can penetrate into the rumen of the ruminant, and finally the operation of the SF6 tracing technology is completed. The device is a device suitable for the detection of ruminant rumen methane by the SF6 method;
[0030] During use, SF6 is used as a tracer gas. First, the permeation tube body 31 is immersed in liquid nitrogen. After standing for 15-20 seconds, a syringe is used to quickly inject SF6 gas into the permeation tube body 31. Due to the low temperature of liquid nitrogen, the gaseous SF6 is quickly converted into a solid state and stored in the permeation tube body 31. Then, the plug 35 is inserted into the open end of the permeation tube body 31, and the sealing strip 37 is inserted into the sealing slot 34 for sealing. The first magnetic layer 36 and the second magnetic layer 38 are attracted to each other, so that the plug 35 is easily inserted into the open end of the permeation tube body 31 to seal it. The operation is convenient and the sealing effect is good. Then, the permeation tube 3 is inserted into the protective shell 1. During the insertion process, the arc head 32 first contacts the arc clamping block 4 The top of the infiltration tube 3 is inserted downward, and the downward movement of the infiltration tube 3 will squeeze the arc-shaped clamping blocks 4 to both sides, thereby squeezing the spring 51. At this time, the spring 51 is in a compressed state. When the infiltration tube 3 moves down to the middle, the two arc-shaped clamping blocks 4 will be pushed to move relatively toward the middle under the rebound force of the spring 51, so that the arc-shaped clamping blocks 4 are stuck in the card groove 33, thereby completing the fixation of the infiltration tube 3. The operation is convenient and the fixation is more firm. Subsequently, it is placed in a biochemical incubator for anaerobic culture at 39°C for 2-3 months and then fed for use. The SF6 in the infiltration tube body 31 and the methane gas produced by the fermentation of the rumen of ruminants are synchronously collected, and the concentrations of the two are detected by a gas chromatograph to obtain the methane production of ruminants, thereby completing the operation of detecting ruminant rumen methane.
