Description

Technical Field

[0001] This utility model relates to the field of animal husbandry technology, and in particular to a methane gas collection device for ruminant livestock. Background Technology

[0002] Anthropogenic sources of methane emissions include the production and consumption of fossil fuels, landfilling of waste, and agricultural and livestock production activities. In livestock farming activities involving ruminants such as cattle, sheep, and goats, methane gas produced during intestinal fermentation during rumination is naturally emitted to the outside world through respiration and other means.

[0003] To obtain detailed methane emission data, operators would raise a certain number of livestock indoors and collect accurate data by collecting ambient air samples during the raising process. However, when monitoring and collecting data on large livestock such as yaks, their large size requires a larger raising environment or even semi-open raising. Therefore, methane gas data collected by only collecting ambient air samples cannot be completely accurate and has a significant impact on subsequent actual experiments. Utility Model Content

[0004] The purpose of this invention is to solve the following problems existing in the prior art:

[0005] Previous experimental setups for monitoring and collecting air samples from ruminants were complex and cumbersome, requiring highly skilled operators. They were unsuitable for outdoor or open / semi-open barns, or required specific site conditions, or severely hampered animal activity, thus failing to accurately simulate normal animal respiration, as seen in techniques like respiratory laboratory techniques and head-mounted gas collection. For all ruminants, previous setups were ineffective at monitoring and collecting samples from near the animal. Gas accumulation in enclosed barns increased the uncertainty of results and potentially increased the cost of additional ventilation equipment. For large animals like yaks, their size necessitates larger enclosures or even semi-open housing. Therefore, simply collecting indoor air is unsuitable for semi-open barns, or the methane data collected in enclosed barns may be inaccurate, significantly impacting subsequent experiments and increasing the resource consumption associated with large barns.

[0006] To address one or more problems existing in the prior art, this utility model provides a methane gas collection device for ruminant livestock, characterized in that: it includes an integrated back pad (1), a gas path device (2), and an adjusting ring sleeve group (3). In the integrated back pad (1), a strap (102) is provided at the bottom of the back pad body (101). There are four straps (102) in total, which are arranged in pairs at the bottom of the back pad body (101). The two straps (102) in each group are respectively arranged on both sides of the back pad body (101). Each pair of corresponding straps between the two groups is fastened together by a connecting buckle (103).

[0007] Preferably, in the integrated back pad (1), a bottle sleeve (104) is provided on the top of the back pad body (101), and a strap (105) is provided on the surface of the bottle sleeve (104) to connect with the back pad body (101) to fix the bottle sleeve (104) on the back pad body (101). The bottle sleeve (104) is a cylindrical tubular structure.

[0008] Preferably, the gas circuit device (2) includes a gas collecting bottle (201), which is a vacuum bottle. An angle valve (202) is provided at its input end. The angle valve (202) is connected in series to the throttle bend (204) through an adapter hose (203). The throttle bend (204) is connected to the air guide pipe (206) through a quick interface (205).

[0009] Preferably, in the gas path device (2), a sampling hole tube (207) is provided at the end of the gas guide tube (206).

[0010] Preferably, in the gas path device (2), the gas guide tube (206) is divided into a flexible tube part and a rigid tube part, both of which are made of rubber and have elasticity. The part near the sampling hole tube (207) is the rigid tube part, and the part near the gas collecting bottle (201) is the flexible tube part. The two parts are divided by the neck adjustment ring (303).

[0011] Preferably, the adjustment ring assembly (3) has two adjustment rings, namely the head adjustment ring (301) and the neck adjustment ring (303), both of which are set on the side of the air guide tube (206) near the sampling hole tube (207) and are spaced apart from each other.

[0012] Preferably, in the adjusting ring assembly (3), a fixing ring (302) is provided on the surface of the head adjusting ring (301).

[0013] Preferably, in the adjustment ring assembly (3), two pairs of elastic bands (304) are respectively provided on both sides of the neck adjustment ring (303), one end of which is connected to the adjustment ring (304), and the other end is connected to the Velcro (306) through the rubber band (305).

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a bottle sleeve to attach the gas cylinder to the back pad of a ruminant, and connects it to the air duct via a quick connector. The air duct has an adjustable ring with an elastic band and a fixing ring, ensuring that the sampling port is always positioned at the ruminant's mouth and nose. When the operator opens the vacuum-sealed gas collection bottle, the throttling bend automatically limits the air intake and maintains a constant gas absorption rate. Air from the ruminant's mouth and nose is drawn into the gas collection bottle through the sampling port and air duct by vacuum suction. When the gas collection bottle is full, it can be quickly replaced via the quick connector, and the gas in the replaced bottle can be tested. The sampling area is always located at the ruminant's mouth and nose, ensuring the accuracy of the collected gas and thus guaranteeing more scientifically sound experimental data. The quick connector also reduces the difficulty of replacing the gas cylinder, thus reducing the experience required of the operator. The adjustable ring design allows the air duct to be securely fixed to the ruminant's head with convenient and quick operation, while automatically limiting the air duct's position. The back pad features multiple designs to adapt to experiments conducted in different seasons, while minimizing stress on ruminants. The gas collection bottle is positioned away from the head and neck of the ruminants, minimizing impact on their normal activities and widely adaptable to domestic livestock pen designs, ensuring unimpeded feeding and guaranteeing the scientific rigor of the experimental data. In summary, this invention surpasses existing data collection methods, with its core advantage being: less stress on animals while adapting to a wider range of experimental environments.

[0035] Furthermore, in a preferred embodiment, the gas path device 2 has an adjusting ring sleeve 3 fitted around the outside of the gas guide tube 206. The gas guide tube 206 is divided into a flexible tube section and a rigid tube section, both made of rubber and having a certain degree of elasticity. The part closer to the sampling port tube 207 is the rigid tube section, and the part closer to the gas collecting bottle 201 is the flexible tube section. The two parts are separated by the neck adjusting ring 303.

[0036] Furthermore, as a preferred embodiment, the specific diameter and length of the air duct 206 can be modified to adapt to different types of ruminant livestock, and the specific modifications are made based on the implementation situation and actual measurement data of the animal's body size.

[0040] Furthermore, as a preferred embodiment, the specific length, width, or the sum of the lengths of the elastic band 304, rubber band 305, and Velcro 306 can be modified to suit different types of ruminant livestock, and the specific modifications are made based on the implementation situation and actual measurement data of the animal's body size.

[0041] Working principle description: Tighten the strap 105 to fix the bottle sleeve 104 to the back pad body 101. By fastening the connecting buckle 103 on the strap 102, the integrated back pad 1 can be fixed to the back of the ruminant. During use, deploy the air passage device 2 and the adjusting ring assembly 3. Insert the vacuum-sealed gas collecting bottle 201 into the bottle sleeve 104 on the surface of the integrated back pad 1, and connect the appropriate length of the air guide tube 206 to the gas collecting bottle 201. Then, move the neck adjusting ring 303, which has elastic bands 304 on both sides, to other symmetrical fixed positions on the animal's horns or head, ensuring that it passes through the two ends of the elastic bands 304. Between the rubber bands 305, the rubber bands 305 are wrapped around the head of the ruminant and converge at the neck of the ruminant and are connected to each other by Velcro 306. At this time, the neck adjustment ring 303 is fixed between the animal's horn or other symmetrical fixed positions on the head, and the air guide tube 206 is limited. Then, the sampling hole tube 207 at the end of the air path device 2 is adjusted to be close to the mouth and nose of the ruminant, and the position of the adjustment ring 301 with the fixing ring 302 is adjusted. The fixing ring 302 is connected to the ruminant's muzzle and fixed in position using a cable tie or soft rope. At this time, the position of the adjustment ring sleeve 3 is fixed and the air guide tube 206 inside is limited. After ensuring that the sampling port tube 207 is always located at the mouth and nose of the ruminant, the adapter hose 203 will provide a certain degree of freedom at the connection point while allowing bending. At this time, the air circuit device 2 can be adjusted to a suitable angle. The operator opens the vacuum gas collection bottle 201 and adjusts the knob of the angle valve 202 to an appropriate position. The throttling bend 204 will automatically limit the air intake and keep the air intake constant. The vacuum suction generated by the gas collection bottle 201 is transmitted through the air guide tube 206 and the sampling port tube 207 to automatically collect air from the mouth and nose of the ruminant. When the gas collection bottle 201 is full, it can be quickly replaced through the quick interface 205 so that the gas collection bottle 201 can be replaced at any time and the gas in it can be tested.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art and those who have consulted this utility model should understand that this utility model is not limited to the above embodiments.
