[0025] Embodiment 2: As Figures 9-11As shown in the figure, an air pump 516 is fixedly connected to the top of the connecting frame 501.

The lower end surface of the air pipe 517 is fixedly connected to a blowing hood 518, and the blowing hood 518 is located outside the output pipe 515.

[0026] Steps of using the present invention: While the sample flows out at the position of the measuring cylinder 508, the air pump 516 is started. After the air pump 516 operates, it can blow air downward from the position of the blowing hood 518 through the connection of the air pipe 517. The blowing hood 518 blows out an annular air flow downward, and this annular air flow corresponds to the inner wall position of the measuring cylinder 508. At this time, under the action of the air flow, the sample attached to the inner wall of the measuring cylinder 508 can be blown down and flow into the sampling cylinder 414, so that all the samples accurately weighed and measured in the measuring cylinder 508 are sent out, further improving the measurement accuracy.

[0027] Embodiment 3: As Figures 6-8 As shown in the figure, a limit sleeve 410 is sleeved on the outer surface of the drive shaft 405. A plurality of grooves 407 are evenly formed on the outer surface of the drive shaft 405. The limit sleeve 410 is inserted and connected with the grooves 407. A turntable 411 is fixedly connected to the outer surface of the limit sleeve 410. A plurality of supports 412 are evenly and fixedly connected to the top of the turntable 411.

A circular ring 421 is fixedly connected to the bottom of the installation frame 420. A toothed ring 422 is fixedly connected to the bottom of the circular ring 421. The position of the roller 413 is matched with that of the toothed ring 422. A support plate 408 is fixedly connected to the lower end surface of the drive shaft 405. A plurality of second springs 409 are evenly and fixedly connected to the top of the support plate 408. The upper end surface of the second spring 409 is fixedly connected to the bottom of the turntable 411.

[0028] Steps of using the present invention: While the turntable 411 rotates, the roller 413 contacts the toothed ring 422. When the roller 413 contacts the inclined surface of a single tooth on the surface of the toothed ring 422, the second spring 409 will be in a compressed state. When the roller 413 disengages from its inclined surface, the roller 413 will instantly lose support. At this time, the roller 413 will bounce up and contact the flat surface position of the toothed ring 422. Therefore, in the rotating state of the turntable 411, the continuous contact between the roller 413 and the toothed ring 422 will cause the turntable 411 to vibrate. After the sample is shaken, air bubbles can be eliminated, which plays a role in improving the accuracy of sample analysis and detection.

[0029] The effects and working principle achieved by the entire mechanism are as follows: When the oilfield high-pressure physical property analyzer is in use, the extraction pump 513 and the extraction head 514 are used in cooperation to extract the crude oil sample. The extracted sample will be sent out from the output pipe 515. When the sample is sent out from the output pipe 515, it will flow into the corresponding measuring cylinder 508 below. At this time, the bottom opening of the measuring cylinder 508 is blocked by the moving seat 510. The weight of the measuring cylinder 508 and the moving seat 510 is supported by the stabilizing frame 507. Through the connection of the sliding rod 504 and the pressing plate 505, the overall weight of the stabilizing frame 507 will be applied to the surface of the weighing sensor 506. At this time, through the numerical change of the weighing sensor 506, the weight of the sample added to the measuring cylinder 508 can be accurately controlled. After the quantitative sample is added to the measuring cylinder 508, the extraction pump 513 is stopped, and the fourth electric push rod 424 is started to extend to drive the trigger plate 425 to displace for feeding; After the trigger plate 425 displaces, it can push the follower plate 512 to displace. The follower plate 512 drives the moving seat 510 to move simultaneously through the connection of the third extension rod 511 and compresses the fourth spring 509 to contract. At this time, the moving seat 510 moves away from the bottom opening position of the measuring cylinder 508. After feeding, the fourth electric push rod 424 contracts and resets, and the moving seat 510 is driven to reset by the resilience of the fourth spring 509. The quantitatively weighed sample in the measuring cylinder 508 will flow into the sampling cylinder 414 below. The bottom of the sampling cylinder 414 is blocked by the second baffle 418. While the sample flows out from the measuring cylinder 508, the air pump 516 is started. After the air pump 516 operates, it can blow air downward from the air blowing cover 518 through the connection of the air pipe 517. The air blowing cover 518 blows out an annular air flow, and this annular air flow corresponds to the inner wall position of the measuring cylinder 508. At this time, under the action of the air flow, the sample attached to the inner wall of the measuring cylinder 508 can be blown down and flow into the sampling cylinder 414, so that all the samples accurately weighed and measured in the measuring cylinder 508 are sent out, further improving the measurement accuracy. After the sampling cylinder 414 below the measuring cylinder 508 completes the sample collection, the position of the sampling cylinder 414 is adjusted by the operation of the motor 402; After the motor 402 operates, it can drive the first gear 404 to rotate through the connection of the rotating shaft 403. When the first gear 404 rotates, it drives the drive shaft 405 to rotate through the engagement with the second gear 406. The drive shaft 405 can drive the turntable 411 to rotate through the connection of the limit sleeve 410. At this time, the turntable 411 drives a plurality of sampling cylinders 414 to rotate. At this time, the sampling cylinder 414 that has completed discharging is sent out, and the next empty sampling cylinder 414 will rotate to the lower part of the measuring cylinder 508 to continue the sample weighing and feeding; While the turntable 411 is rotating, through the combined use of the fixed-state mounting frame 420, the ring 421, and the toothed ring 422, the sample in the sampling cylinder 414 can be shaken. After the sample is shaken, air bubbles can be eliminated, which plays a role in improving the accuracy of sample analysis and detection. When the turntable 411 rotates, it can drive the roller 413 to rotate along with it through the connection of the support 412. The turntable 411 is connected to the drive shaft 405 through the limit sleeve 410. The insertion strips on the inner wall of the limit sleeve 410 are inserted into the inner wall of the groove 407, so that the turntable 411 and the drive shaft 405 are in a freely sliding relationship up and down. The bottom of the turntable 411 is supported by the second spring 409. Therefore, at this time, the turntable 411 is in a state of being pushed up by the second spring 409. At this time, the roller 413 is in contact with the toothed ring 422. When the roller 413 contacts the inclined surface of a single tooth on the surface of the toothed ring 422, the second spring 409 will be in a compressed state. When the roller 413 disengages from its inclined surface, the roller 413 will instantly lose support. At this time, the roller 413 will bounce up and contact the flat surface position of the toothed ring 422. Therefore, in the rotating state of the turntable 411, the continuous contact between the roller 413 and the toothed ring 422 will cause the turntable 411 to vibrate. Under the action of the vibration, the sample in the sampling cylinder 414 is shaken to eliminate air bubbles; With the continuous intermittent operation of the motor 402, the sampling cylinder 414 containing a quantitative sample has been displaced to a position above the box body 305. At this time, the sample in the sampling cylinder 414 is sent out for analysis and detection. Starting the third electric push rod 315 to extend can drive the displacement plate 316 to move along. After the displacement plate 316 moves, it can synchronously push the first extension rod 321 and the second extension rod 419 to move. At this time, the first baffle 320 and the second baffle 418 will be pushed open at the same time. After the first baffle 320 is pushed open, the upper part of the box body 305 is opened. At the same time, the first baffle 320 drives the first blocking frame 319 to move, so that the first spring 318 is compressed. After the second baffle 418 is pushed open, the bottom of the sampling cylinder 414 is opened. When the second baffle 418 moves, it drives the second blocking frame 417 to move, so that the third spring 416 is compressed. At this time, the sample stored in the sampling cylinder 414 will flow out into the box body 305. Above the sampling cylinder 414 at this position, the above-mentioned set of air pumps 516, air pipes 517, and blowing covers 518 can be fixedly installed for use to ensure that the weight loss of the sample in the sampling cylinder 414 is less during transfer. The sample that enters the box body 305 will be blocked by the box body 305 and the sealing plate 314, so that the sample stays on the surface of the detection head 302 for analysis and detection; When starting the analysis and detection, the third electric push rod 315 is activated to contract and reset. The resilience of the first spring 318 and the third spring 416 drives the first baffle 320 and the second baffle 418 to reset. At this time, the first baffle 320 resets to block the top of the box body 305, making the inside of the box body 305 in a closed state. The first electric push rod 307 is activated to contract to pressurize the inside of the box body 305, that is, the space where the sample is located. The first electric push rod 307 drives the piston 310 to displace through the connection of the support plate 308 and the moving rod 309. The piston 310 pushes into the pressure pipe 306, compressing the air inside the box body 305, which plays a role in pressurization. After completing the high-pressure physical property analysis and detection, the third electric push rod 315 is activated to extend and drive the first baffle 320 to displace, opening the top of the box body 305 to release pressure and exhaust gas. Then the second electric push rod 311 is activated to contract. After the second electric push rod 311 operates and contracts, it can drive the two sealing plates 314 to displace synchronously through the connection of the linkage frame 312 and the linkage rod 313. The displacement of the sealing plates 314 can scrape the sample inside the box body 305 towards the collection box 303. At this time, the sample that has completed the analysis and detection will be scraped into the collection box 303 for collection, and at the same time, the surface position of the instrument body 301 is cleaned. At this time, a sample analysis and detection is completed. Next, through the coordinated operation of the detection component 3, the sampling component 4, and the extraction component 5, the processes of automatically extracting, weighing and measuring, sending for detection, and cleaning the detection position of the sample can be completed, effectively improving the automation degree when the analyzer is used, and thus improving the work efficiency.
