Description

Technical Field

[0001] The present invention relates to the field of gas metabolism detection, and more specifically, to a gas metabolism detection device and method for ruminants. Background Art

[0002] Ruminants refer to even-toed ungulates. Some of these animals have a stomach divided into four parts: the rumen, the reticulum, the omasum, and the abomasum. After swallowing food, it first enters the rumen and then the reticulum, and then returns to the mouth for thorough chewing, and then enters the omasum, and finally the abomasum, such as cattle, sheep, and deer.

[0003] As a ruminant, cattle have a special digestive system. They chew food roughly and then swallow it. Then, initial physical and chemical digestion occurs in the rumen and reticulum. After that, the food returns to the mouth for further chewing (i.e., rumination) for more complete digestion and absorption. During the feeding process of cattle, a gas metabolism detection device is needed to detect the metabolic gases of cattle, study the energy metabolism, energy requirements, and feed energy value evaluation of cattle. By measuring the gas components and amounts produced by cattle during breathing per unit time, the heat production in their bodies and the results of energy substance metabolism can be calculated, providing a basis for formulating a scientific feeding management plan.

[0004] In the existing technology, as disclosed in a document with the publication number CN104642160B, a device for monitoring the metabolic gases of farm animals is disclosed. Although this device can detect the metabolic gases of farm animals, in actual operation, a key problem is faced. When the farm animals carry out metabolic activities in the device, the generated gases will diffuse throughout the interior of the box. Due to the relatively spacious interior space of the box, this leads to the dilution of the concentration of metabolic gases in the box. This dilution effect will directly affect the accuracy and reliability of gas detection, and thus have an adverse impact on the final analysis results. Summary of the Invention

[0015] A gas metabolism detection method for ruminants includes the following steps: S1. Two electric slide rails drive a connecting frame to move through first sliders respectively. When the two connecting frames move, they drive a first collar and a second collar to move respectively. When the ends of the two connecting frames contact, at this time, the two first collars contact each other to achieve closure, and the two second collars contact each other to achieve closure. At this time, the first collar and the second collar are sleeved on the cow, and the hind legs of the cow are respectively located in the reserved slots. When the first collar and the second collar are closed, at this time, the arc arm passes through the mounting hole on the docking ring. Under the torsion of the torsion spring, the end of the clamping arm rotates to the outside of the arc arm. By rotating the adjusting screw rod, the arc plate drives the arc arm to move. At this time, the end of the clamping arm at the end of the arc arm presses the docking ring, and the two docking rings are fixed together, so as to realize the installation of the first collar and the second collar. S2. Press the first connecting ring onto the two closed second connecting rings. At this time, the sealing ring is pressed into the sealing groove on the second connecting ring. During the extrusion process, the end parts of multiple abutting plates respectively exert extrusion on the second connecting ring. At this time, the abutting plates slide along the support plate and the sliding rod. Under the elastic force of the first spring, the abutting plates fix the first connecting ring and the second connecting ring together. At this time, the connecting cover is buckled on the hip part of the cow. During the installation of the two connecting frames, the end of the first screw rod moves towards the connecting block at this time. The inclined surface at the end of the clamping cone extrudes the end surface of the connecting block, causing the clamping cone to slide into the first screw rod. When the clamping cone slides into the connecting block, the end of the clamping cone contacts the guiding convex part and is guided by the guiding convex part, causing the first screw rod to rotate. When the first screw rod rotates, it drives the limiting block to rotate. The limiting block drives the extending arm to swing through the swing arm. At this time, the extending arm can slide along the support shaft, thus facilitating the rotation of the first screw rod and enabling the multiple clamping cones on the first screw rod to quickly be stuck inside the hexagonal card slots in the connecting block; S3. Drive the worm to rotate through the motor, drive the worm gear to rotate through the worm, drive the coupling sleeve to rotate through the worm gear. The coupling sleeve drives the first screw rod to rotate through the connecting block, and the coupling sleeve simultaneously drives the second screw rod to rotate. At this time, multiple limiting blocks respectively move spirally along the first screw rod and the second screw rod. The limiting block drives the extending arm to move through the swing arm, the extending arm drives the support arm to move through the support shaft, drives the connecting arm to move through the support arm, drives the sealing plate to move through the connecting arm, drives the clamping plate to move through the sealing plate, so that the ends of the two clamping plates contact. At this time, the connecting pieces on the first arc piece and the second arc piece contact. At the same time, the semi-circular convex part at the end of the first rubber airbag is inserted into the semi-circular arc groove at the end of the second rubber airbag; S4. The two air pumps simultaneously inject gas into the first rubber airbag and the second rubber airbag, causing the first rubber airbag and the second rubber airbag to expand. At this time, the outer walls of the first rubber airbag and the second rubber airbag respectively come into full contact with the body part of the cow, thereby realizing the sealing of the space between the second sleeve ring and the connecting cover. When the first rubber airbag and the second rubber airbag expand, the semi-circular convex part is in full contact with the inner wall of the semi-circular arc groove, improving the sealing performance; S5. During the metabolism of the cow, gas will be metabolized at the same time. The metabolites are blocked by the baffle and fall into the connecting cover. The transfer pump transports the metabolic gas to the inside of the detection device through the air delivery pipe, and the detection device detects the metabolic gas; S6. By rotating the adjusting screw rod in the reverse direction, the clamping arm is disengaged from the extrusion of the docking ring. By pulling the clamping rod to drive the abutting plate to move, the clamping rod is stuck inside the clamping hole on the sliding rod. At this time, the abutting plate is disengaged from the blockage of the second connecting ring, so that the connecting cover can be disassembled, facilitating the cleaning of the metabolites of the cow. By driving the connecting frame to move respectively through the electric slide rail, the first sleeve ring and the second sleeve ring are separated, thus facilitating the disassembly of the device.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the present invention, two electric slide rails drive the connection frame to move through the first sliders respectively. When the two connection frames move, they drive the first collar and the second collar to move respectively. When the ends of the two connection frames contact each other, at this time, the two first collars contact each other to achieve closure, and the two second collars contact each other to achieve closure. At this time, the first collar and the second collar are sleeved on the cow, and the hind legs of the cow are respectively located in the reserved grooves. By rotating the adjusting screw, the clamping arm fixes the two docking rings together, thereby realizing the installation of the first collar and the second collar. By driving the first screw and the second screw to rotate through the motor, two air pumps inject gas into the first rubber airbag and the second rubber airbag at the same time, causing the first rubber airbag and the second rubber airbag to expand. At this time, the outer walls of the first rubber airbag and the second rubber airbag are in full contact with the cow body parts respectively, thereby realizing the sealing of the space between the second collar and the connection cover, effectively controlling the metabolic gas in a smaller space, avoiding the diffusion of the metabolic gas, and improving the accuracy and reliability of gas detection.

[0017] 2. In the present invention, the ends of the two clamping plates contact each other. At this time, the connecting pieces on the first arc piece and the second arc piece contact each other. At the same time, the semi-circular convex part at the end of the first rubber airbag is inserted into the semi-circular arc groove at the end of the second rubber airbag. When the first rubber airbag and the second rubber airbag expand, at this time, the semi-circular convex part is in full contact with the inner wall of the semi-circular arc groove, improving the sealing performance.

[0026] Working principle: The two electric slide rails 302 drive the connecting frames 304 to move through the first sliders 303 respectively. When the two connecting frames 304 move, they drive the first collar 201 and the second collar 203 to move respectively. When the ends of the two connecting frames 304 come into contact, at this time, the two first collars 201 come into contact with each other to achieve closure, and the two second collars 203 come into contact with each other to achieve closure. At this time, the first collar 201 and the second collar 203 are sleeved on the cow. The hind legs of the cow are respectively located in the reserved grooves 202. When the first collar 201 and the second collar 203 are closed, at this time, the arc arm 210 passes through the mounting hole 207 on the docking ring 206. Under the torque action of the torsion spring 214, the end of the clamping arm 215 rotates to the outside of the arc arm 210. By rotating the adjusting screw rod 208, the arc plate 209 drives the arc arm 210 to move. At this time, the end of the clamping arm 215 at the end of the arc arm 210 squeezes the docking ring 206, and fixes the two docking rings 206 together, so as to realize the installation of the first collar 201 and the second collar 203; Press the first coupling ring 106 against the two closed second coupling rings 204. At this time, the sealing ring 116 is pressed into the sealing groove 205 on the second coupling ring 204. During the extrusion process, the end parts of multiple abutting plates 109 respectively exert extrusion on the second coupling ring 204. At this time, the abutting plates 109 slide along the support plate 108 and the sliding rod 110. Under the elastic force of the first spring 111, the abutting plates 109 fix the first coupling ring 106 and the second coupling ring 204 together. At this time, the connecting cover 104 is buckled on the hip part of the cow. During the installation of the two connecting frames 304, the end of the first screw rod 401 moves towards the connecting block 408 at this time. The inclined surface 414 at the end of the clamping cone 413 exerts extrusion on the end surface of the connecting block 408, causing the clamping cone 413 to slide into the first screw rod 401. When the clamping cone 413 slides into the connecting block 408, the end of the clamping cone 413 contacts the guiding convex part 409 at this time and is guided by the guiding convex part 409, causing the first screw rod 401 to rotate. When the first screw rod 401 rotates, it drives the limiting block 316 to rotate. The limiting block 316 drives the extension arm 313 to swing through the swing arm 315. At this time, the extension arm 313 can slide along the support shaft 311, so as to facilitate the rotation of the first screw rod 401, enabling the multiple clamping cones 413 on the first screw rod 401 to quickly be stuck inside the hexagonal card slots 410 in the connecting block 408; Drive the worm 405 to rotate through the motor 404, drive the worm gear 418 to rotate through the worm 405, drive the coupling sleeve 407 to rotate through the worm gear 418. The coupling sleeve 407 drives the first screw rod 401 to rotate through the connecting block 408. The coupling sleeve 407 simultaneously drives the second screw rod 402 to rotate. At this time, the protrusions of the limiting block 316 are restricted by the second limiting groove 308 and respectively move spirally along the first screw rod 401 and the second screw rod 402. At the same time, the protrusions of the limiting block 316 slide along the inner wall of the second limiting groove 308. The limiting block 316 drives the extension arm 313 to move through the swing arm 315. The extension arm 313 drives the support arm 310 to move through the support shaft 311, drives the connecting arm 309 to move through the support arm 310, drives the sealing plate 318 to move through the connecting arm 309, drives the clamping plate 317 to move through the sealing plate 318, so that the ends of the two clamping plates 317 contact. At this time, the connecting pieces 324 on the first arc piece 319 and the second arc piece 322 contact. At the same time, the semi-circular convex part 321 at the end of the first rubber airbag 320 is inserted into the semi-circular arc groove 325 at the end of the second rubber airbag 323; Two air pumps 326 simultaneously inject gas into the first rubber airbag 320 and the second rubber airbag 323, causing the first rubber airbag 320 and the second rubber airbag 323 to expand. At this time, the outer walls of the first rubber airbag 320 and the second rubber airbag 323 are respectively in full contact with the body part of the cow, thereby realizing the sealing of the space between the second sleeve ring 203 and the connecting cover 104. When the first rubber airbag 320 and the second rubber airbag 323 expand, the semi-circular convex part 321 is in full contact with the inner wall of the semi-circular arc groove 325 at this time, improving the sealing performance; During the metabolic process of cattle, gases are simultaneously metabolized. The metabolites are blocked by the baffle 107 and fall into the connection cover 104. The transfer pump 105 transports the metabolic gases to the inside of the detection device 102 through the gas pipeline 103, and the detection device 102 detects the metabolic gases. By rotating the adjustment screw 208 in the reverse direction, the clamping arm 215 is disengaged from the extrusion of the docking ring 206. By pulling the clamping rod 114, the abutting plate 109 is driven to move, and the clamping rod 114 is stuck inside the clamping hole 113 on the sliding rod 110. At this time, the abutting plate 109 is disengaged from the blocking of the second connecting ring 204, so that the connection cover 104 can be disassembled, facilitating the cleaning of the metabolites of cattle. By driving the connection frame 304 to move respectively through the electric slide rail 302, the separation of the first sleeve ring 201 and the second sleeve ring 203 is realized, thus facilitating the disassembly of the device.
