[0013] Furthermore, the scraping and anti-damage mechanism is provided with a damping rod, and the middle end of the damping rod passes through the installation fixing plate, and the shape of the fixing plate is "T" shaped, and a buffer plate is fixedly installed at the output end of the damping rod, and a cleaning cotton block and a scraper are fixedly installed on the inner side of the buffer plate.

[0014] Furthermore, the cleaning cotton block and the scraper are both arc-shaped, and the inner sides of the cleaning cotton block and the scraper are in contact with the output end of the electric telescopic rod, and the cleaning cotton block is located at the upper end of the scraper.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. Before use, the servo motor on the bracket can drive the threaded rod to rotate and adjust the movable block. Under the limit of the bracket, the movable block can move left and right to adjust the position with the rotation of the threaded rod. When the movable block is adjusted to a suitable position, the electric telescopic rod is started. The start of the electric telescopic rod can drive the sampling suction head to descend and enter the oil barrel of the oil filling machine to extract oil. After the sampling suction head is embedded in the oil filling machine, the effect of convenient sampling can be achieved, which is convenient for the staff to operate.

At this time, when the output end of the electric telescopic rod is retracted, the adjusting rod on the inner side of the fixed plate is used. Since both ends of the adjusting rod are rotatably installed, the oil stains on the output end of the electric telescopic rod can be scraped off by the scraper when it is retracted, and then the cleaning cotton block can be used to prevent residues from entering the interior of the electric telescopic rod, thereby preventing damage to the sampler and increasing the service life of the sampler.

[0024] 2. As the output end of the electric telescopic rod rises and falls, it can drive the tooth plate to move up and down. The up and down movement of the tooth plate drives the gear rod meshing with it to rotate. The rotation of the gear rod controls the cam to rotate, thereby improving the knocking effect, so that the sampling part of the sampler can vibrate when the height is adjusted. In this way, after the sampling is completed, the oil stains remaining at the sampling tip position can vibrate and fall to reset, saving resource consumption and preventing oil waste.

[0025] 3. During use, as the sampling suction head and the extraction pump draw the oil through the telescopic bellows, it enters the storage box. The oil entering the storage box is first filtered through the filter screen. If there are impurities after filtration, they will be presented on the filter screen and can be observed through the transparent plate on the upper end of the storage box, so that the staff can quickly check the quality of the oil first, and then use professional machines to test the oil. Due to the inclined shape of the lower end of the card block, the card block can automatically rise and squeeze the pressure spring when embedded, until the position of the card block corresponds to the card slot. Under the action of the pressure spring, the card block automatically engages in the card slot, realizing quick disassembly and installation, which is convenient for the staff to use and easy to clean and replace.

[0038] Embodiment 1: Figure 1-Figure 6The technical scheme shown is a sampler for random inspection of oil products in an oiling machine. In order to solve the problem that the oil impurities enter the interior and are easily damaged, the following is disclosed: a bracket 1 and a servo motor 2 fixedly installed on the left side of the bracket 1, and a threaded rod 3 is fixedly installed on the output end of the servo motor 2, and a movable block 4 is threadedly installed on the surface of the threaded rod 3, and an electric telescopic rod 5 is installed through the front end of the movable block 4, and a sampling suction head 6 is fixedly installed on the lower output end of the electric telescopic rod 5, and a telescopic bellows 7 is connected to the rear of the upper end of the sampling suction head 6, and the left end of the telescopic bellows 7 is connected to a storage box 9, and a scraping and damage prevention mechanism is provided at the output end of the electric telescopic rod 5, and the scraping and damage prevention mechanism is provided with a fixed plate 11, and the inner side of the fixed plate 11 is fixedly installed on the outer side of the front end of the movable block 4, and an extraction pump 8 is provided at the middle end of the telescopic bellows 7, and the front end of the extraction pump 8 is fixedly installed on the rear end of the movable block 4, and the front end of the storage box 9 is penetrated below. A discharge valve 10 is installed, and a damping rod 12 is provided for scraping and anti-damage mechanism, and the middle end of the damping rod 12 penetrates and is installed with a fixed plate 11, and the shape of the fixed plate 11 is "T" shaped, and a buffer plate 13 is fixedly installed at the output end of the damping rod 12, and a cleaning cotton block 14 and a scraper 15 are fixedly installed on the inner side of the buffer plate 13, and the cleaning cotton block 14 and the scraper 15 are both arc-shaped, and the inner sides of the cleaning cotton block 14 and the scraper 15 fit the output end of the electric telescopic rod 5, and the cleaning cotton block 14 is located at the upper end of the scraper 15, an adjusting rod 16 is rotatably installed on the inner side of the fixed plate 11, and a moving block 17 is rotatably installed on the inner side of the adjusting rod 16, and a positioning rod 18 is installed through the middle end of the moving block 17, and the front and rear ends of the positioning rod 18 are fixedly installed on the outer side of the buffer plate 13, and a buffer spring 19 is sleeved on the surface of the positioning rod 18, and the front and rear ends of the buffer spring 19 are arranged between the moving block 17 and the buffer plate 13;

[0039] Before use, the servo motor 2 on the bracket 1 can drive the threaded rod 3 to rotate and adjust the movable block 4. Under the limit of the bracket 1, the movable block 4 can move left and right with the rotation of the threaded rod 3. When the movable block 4 is adjusted to a suitable position, the electric telescopic rod 5 is started. The start of the electric telescopic rod 5 can drive the sampling suction head 6 to descend and enter the oil barrel of the oil filling machine to extract oil. After the sampling suction head 6 is embedded in the oil filling machine, the extraction pump 8 is started. Under the action of the telescopic bellows 7, the extraction pump 8 extracts the oil into the storage box 9 for storage. When the subsequent detection is carried out, the extracted oil is released through the discharge valve 10, thereby achieving the effect of convenient sampling, which is convenient for the staff to operate, simple and convenient, easy to use, and has a low operating coefficient. At the same time, After the sample suction head 6 is extracted, the sampling suction head 6 can be stretched and reset through the setting of the electric telescopic rod 5.

At the same time, under the setting of the damping rod 12, the reciprocating vibration of the buffer spring 19 is avoided. In this way, when the electric telescopic rod 5 is contracted, the oil stains on the output end of the electric telescopic rod 5 can be scraped off by the scraper 15 first, and then the residue can be prevented from entering the electric telescopic rod 5 under the cleaning of the cleaning cotton block 14, so as to prevent the sampler from being damaged and the service life of the sampler can be improved.

[0040] Embodiment 2: Figure 1-Figure 8 The technical solution shown is based on the first embodiment. In order to solve the problem that oil is easily left on the sampler during sampling, the following is disclosed: a tooth plate 20 is installed through the front center of the movable block 4, and an anti-residue mechanism is provided at the front end of the tooth plate 20, and the anti-residue mechanism is provided with a gear rod 21, and the rear end of the gear rod 21 is meshed and installed with the tooth plate 20, the lower end of the tooth plate 20 provided with the anti-residue mechanism is fixedly installed behind the output end of the electric telescopic rod 5, and the surface of the movable block 4 is rotatably installed with the gear rod 21 through a limit sleeve, and cams 22 are fixedly installed on the left and right sides of the gear rod 21, an opening plate 23 is fixedly installed on the outer side of the fixed plate 11, and a knocking plate 24 is slidably connected to the inside of the opening plate 23, and a convex block is provided on the inner side of the knocking plate 24, and a vibration spring 26 is provided between the knocking plate 24 and the fixed plate 11;

[0041] As the output end of the electric telescopic rod 5 rises and falls, the tooth plate 20 can be driven to move up and down. The up and down movement of the tooth plate 20 drives the gear rod 21 meshing therewith to rotate. The rotation of the gear rod 21 controls the cam 22 to rotate. The cam 22 can squeeze the inclined block 25 in both forward and reverse rotations. The inclined block 25 is squeezed and pushes the knocking plate 24 to slide along the inner side of the opening plate 23, so that the knocking plate 24 can reciprocate and knock on the fixed plate 11. Under the action of the vibration spring 26, the knocking effect is improved, so that the sampling part of the sampler can vibrate when the height is adjusted, so that after the sampling is completed, the oil stains remaining at the position of the sampling suction head 6 can be vibrated and reset, saving resource consumption and preventing oil waste.

[0042] Embodiment 3: Figure 1-Figure 10 The technical solution shown is based on the second embodiment.

[0043] When in use, as the sampling suction head 6 and the extraction pump 8 extract the oil through the telescopic bellows 7, it enters the storage box 9. The oil entering the storage box 9 is first filtered through the filter screen 27. If there are impurities after filtration, they will appear on the filter screen 27 and can be observed through the transparent plate at the upper end of the storage box 9, which is convenient for the staff to quickly check the quality of the oil first, and then use a professional machine to test the oil, which can be quickly identified. At the same time, when it is necessary to disassemble the filter screen 27 for cleaning, it can By pulling the handle at the upper end of the card plate 28 to disengage the card plate 28 from the engagement of the card slot 29, the filter screen plate 27 can be pulled out for cleaning by the handle at the front end of the filter screen plate 27. Conversely, when the filter screen plate 27 is inserted, due to the inclined shape of the lower end of the card block, the card block can automatically rise and squeeze the pressure spring 30 when inserted, until the position of the card block corresponds to the card slot 29. Under the action of the pressure spring 30, the card block automatically engages inside the card slot 29, thereby realizing quick disassembly and installation, facilitating use by the staff, and convenient cleaning and replacement.
