Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Embodiment 1: Please refer to Figures 1-4, a food detection sample stirring and pretreatment device convenient for discharging materials, including a stirring barrel 1. On one side of the top of the stirring barrel 1, a crushing barrel 9 is installed. On the top of the crushing barrel 9, a second servo motor 11 is installed, and at the bottom of the second servo motor 11, a crushing paddle 13 is installed. On one side of the top of the crushing barrel 9, a feed pipe 12 is installed. In the middle position of the top of the stirring barrel 1, a motor seat 7 is fixed, and on the top of the motor seat 7, a first servo motor 8 is installed. At the bottom of the first servo motor 8, a rotating shaft 16 is installed, and at the bottom of the rotating shaft 16, a stirring blade 2 is installed. On both sides of the stirring blade 2, first scraping rods 3 are fixed. On one side of the bottom of the stirring barrel 1, a discharge pipe 5 is installed, and at the bottom inside the discharge pipe 5, a valve 4 is arranged. The bottom end of the rotating shaft 16 extends to the bottom of the stirring barrel 1 and is installed with a fifth bevel gear 22. At the bottom of the fifth bevel gear 22, a fourth bevel gear 20 is meshed. Inside the fourth bevel gear 20, a connecting shaft 21 is installed, and one side of the connecting shaft 21 extends to the inside of the discharge pipe 5 and is fixed to the inner side wall of the discharge pipe 5. On the outer side wall of the discharge pipe 5, stirring plates 19 are fixed. There are four groups of stirring plates 19, and the four groups of stirring plates 19 are annularly distributed on the outer side wall of the connecting shaft 21, so that the second stirred material is evenly turned out. There are two groups of first scraping rods 3, and the two groups of first scraping rods 3 are symmetrically distributed about the central axis of the stirring blade 2. The symmetrically distributed first scraping rods 3 have a better cleaning effect on the stirring barrel 1;
[0024] Specifically, as Figure 1 and Figure 3 shown, when the rotating shaft 16 rotates, the fifth bevel gear 22 at the bottom end of the rotating shaft 16 also rotates. The rotation of the fifth bevel gear 22 also drives the fourth bevel gear 20 to rotate. When the fourth bevel gear 20 rotates, the connecting shaft 21 inside it drives the crushing barrel 9 to rotate inside the discharge pipe 5, so that the stirred material is evenly discharged through the rotating crushing barrel 9.
[0025] Embodiment 2: At the top of the outer side wall of the rotating shaft 16, a second bevel gear 17 is installed. On one side of the second bevel gear 17, a rotating rod 15 is arranged, and the rotating rod 15 extends into the crushing barrel 9. On both sides of the rotating rod 15, first bevel gears 14 are fixed. On the side of the first bevel gear 14, a third bevel gear 18 is meshed, and the third bevel gear 18 is movably arranged at the bottom inside the crushing barrel 9. At the top of the third bevel gear 18, a second scraping rod 10 is installed. There are two groups of second scraping rods 10, and the outer side walls of the two groups of second scraping rods 10 are attached to the inner side wall of the crushing barrel 9, which has a better scraping and cleaning effect on the materials adhered to the inner side wall of the crushing barrel 9. The first bevel gear 14 on the left side of the rotating rod 15 is meshed with the second bevel gear 17, and the first bevel gear 14 on the right side of the rotating rod 15 is meshed with the third bevel gear 18;
[0026] Specifically, as Figure 1 and Figure 2As shown, during the stirring process of the rotating shaft 16, the second bevel gear 17 also rotates. The rotation of the second bevel gear 17 drives the engaged rotating rod 15 to rotate. The rotation of the rotating rod 15 drives the first bevel gear 14 to rotate. The rotation of the first bevel gear 14 drives the engaged third bevel gear 18 to rotate. The rotation of the third bevel gear 18 scrapes the inner wall of the crushing barrel 9 through the second scraping rod 10, so that the materials generated during the crushing of the crushing barrel 9 are scraped into the interior of the stirring barrel 1 to avoid waste.
[0027] Embodiment 3: One side of the top end of the stirring barrel 1 is fixedly provided with an observation window 6. A shaft body 24 is installed at the middle position inside the observation window 6. A handle 23 is installed at the top end of the shaft body 24. A cleaning scraping rod 25 is installed at the bottom end of the shaft body 24. The length of the cleaning scraping rod 25 is the same as the distance between the shaft body 24 and the observation window 6. The upper surface of the cleaning scraping rod 25 fits the lower surface of the observation window 6, and the cleaning effect on the observation window 6 is better.
[0028] Specifically, as Figure 1 and Figure 4 shown, people can observe the stirring condition of the materials inside the stirring barrel 1 through the observation window 6. When observing, they can also hold the shaft body 24 and drive the cleaning scraping rod 25 to rotate through the handle 23 to scrape the inner surface of the observation window 6, and clean the observation window 6 when it is dirty, so that the observation window 6 remains clear to better observe the interior of the stirring barrel 1.
[0029] Working principle: When the present utility model is in use, a food sample is taken and put into the interior of the crushing barrel 9 through the feed pipe 12. Then, the crushing paddle 13 driven by the second servo motor 11 will crush the sample. The crushed food sample will fall into the interior of the stirring barrel 1. After adding the corresponding liquid, then the first servo motor 8 is started to drive the stirring blade 2 through the rotating shaft 16 to stir the crushed food sample. During the stirring process of the rotating shaft 16, the second bevel gear 17 also rotates. The rotation of the second bevel gear 17 drives the engaged rotating rod 15 to rotate. The rotation of the rotating rod 15 drives the first bevel gear 14 to rotate. The rotation of the first bevel gear 14 drives the engaged third bevel gear 18 to rotate. The rotation of the third bevel gear 18 scrapes the inner wall of the crushing barrel 9 through the second scraping rod 10, so that the materials generated during the crushing of the crushing barrel 9 are scraped into the interior of the stirring barrel 1 to avoid waste. Then, people can observe the stirring condition of the food sample inside the stirring barrel 1 through the observation window 6. If it is stirred evenly, the observation window 6 is opened to allow the materials to be evenly turned over and discharged under the action of the rotating stirring plate 19.
