Detailed Description

As shown in fig. 1 to 10, the present invention mainly includes a needle tube 1, a handle 15, a scraper 13 and a scraping mechanism, and the present invention will be described in detail with reference to the accompanying drawings.

As shown in figures 1 and 9, the needle tube 1 is a round stainless steel tube, the outer diameter of the needle tube is 1-4cm, a puncture part 11 is arranged at the first end of the needle tube, the puncture part is in a conical structure, and the large end of the puncture part is fixedly connected with the needle tube. The side wall of the needle tube is provided with a plurality of windows 12 which are positioned on the same bus and are square holes and countersunk holes. As shown in fig. 10, a sealing ring 14 is provided inside the windows, and a scraper 13 is provided in each window, while the scraper can be moved out of the window. A handle 15 is fixed to the outer wall of the second end of the needle tube to facilitate the holding of the needle tube. As shown in figure 3, two support rods 16 are arranged on the inner side of the needle tube in pairs, a plurality of warping rods 2 which are arranged at equal intervals up and down are rotatably arranged between the two support rods in pairs, the warping rods correspond to the scraping plates one by one, and the warping rods are fixedly connected with the upper ends of the scraping plates. Stick up and be the obtuse angle contained angle between pole and the scraper blade, be equipped with the torsional spring between stick up pole and bracing piece, in the window was arranged in to the scraper blade under the effect of torsional spring, and scraper blade inside wall and sealing washer contact, and then realize the closure to the window, whole scraper blade was arranged in the window this moment. As shown in fig. 3 to 6, in a natural state, the tilting rod is obliquely arranged, the lower end of the tilting rod is fixedly connected with the upper end of the scraper, the upper end of the tilting rod is hinged with an actuating rod 21, a driven gear 23 is arranged above the actuating rod, a nut 22 is fixed at the bottom of the driven gear, and the upper part of the actuating rod extends into the nut and is in threaded connection with the nut. The upper part of the needle tube is provided with a supporting plate 17, and the nut is rotatably arranged on the supporting plate. A main shaft 25 is rotatably mounted at the center of the support plate, and a drive gear 24, which is engaged with a driven gear as shown in fig. 2, is fixed to the main shaft. The upper end of the main shaft passes through the support plate and then is arranged above the support plate, as shown in fig. 8, a handle 3 is fixed at the top of the main shaft and is arranged above the needle tube. When the handle is rotated, the main shaft can be driven to rotate, so that the driven gear is driven to rotate, the nut is driven to rotate, the actuating rod can be driven to move up and down when the nut rotates, and when the actuating rod moves up, the scraper can be driven to swing, so that the scraper moves out of the needle tube. The handle, the driving gear, the driven gear, the main shaft, the nut, the actuating rod and the warping rod form a scraping mechanism. The squeegee is driven into and out of the window under the action of the squeegee mechanism.

The following describes the usage of the present invention:

(1) the first end of the needle tube is inserted into the food (solid food or liquid food) to be detected;

(2) rotating the handle until the needle tube extends into the food to reach a proper position, driving the scraper to extend out of the needle tube, then continuously pushing the needle tube into the food, and scraping the food fragments by the scraper;

(3) then the handle is rotated reversely, so that the scraping plate retracts into the window, and the scraped food fragments enter the inner side of the needle tube; thus, the food can be sampled, and the sampling is representative because the scrapers are arranged at equal intervals on the needle tube.

After sampling is finished, the needle tube is pulled out of the food, then the handle is rotated, the scraper is moved out of the window, and video fragments in the needle tube are poured out. The puncture part and the needle tube can be in threaded connection for facilitating the taking out of the food fragments, and when the sampled food fragments need to be taken out, the puncture part only needs to be dismounted, and the food fragments are poured out from the needle tube.
