[0004] Existing veterinary drug residue detection devices require stirring the sample and extract before use. However, samples such as feed and soil may contain components of different particle sizes and densities distributed in different layers, making it impossible to uniformly stir all samples. At the same time, sedimentation or stratification may occur during the stirring process, thus affecting the accuracy of the test results. Utility Model Content

[0010] As an improved technical solution, the outer wall of the rotating disk is provided with multiple rotating cavities, and a rotating component is rotatably connected inside the rotating cavity. A stirring fan blade is fixedly connected to the other end of the rotating component.

[0011] As an improved technical solution, a connecting ring is fixedly connected near the upper end of the driven rod. A first rotating groove is formed on the four sides of the outer wall of the connecting ring. A connecting rod is rotatably connected inside the first rotating groove. A sliding groove is formed inside the scraping rod. A sliding rod is fixedly connected inside the sliding groove. A sliding block is slidably connected to the outer wall of the sliding rod. The other end of the connecting rod is rotatably connected to the top of the sliding block.

[0012] As an improved technical solution, the scraper plate has a second rotating groove at one end near the scraper rod, a rotating rod is fixedly connected inside the second rotating groove, and the scraper rod is rotatably connected to the outer wall of the rotating rod.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are:

[0017] 1. This utility model uses a motor to drive a threaded rod to rotate inside a threaded groove, which in turn drives a rotating disk to rotate. At the same time, the stirring blades on the outer wall of the rotating disk rotate vertically through a rotating groove inside the rotating disk, so that the sample and the reaction liquid are thoroughly stirred. As the threaded rod continues to move downward, the scraper plate comes into contact with the inside of the stirring tank, causing the scraper rod to move upward. This allows for different stirring of samples with different densities or viscosities, thus improving the reaction between the sample and the reaction liquid.

[0018] 2. In this invention, when the scraper reaches the bottom, the scraper plate and the scraper are on a horizontal plane. While rotating, it also prevents the sample and reaction liquid from depositing at the bottom, further increasing the stirring effect. Attached Figure Description

[0035] like Figure 4 and Figure 5 As shown in the figure, this embodiment provides a veterinary drug residue detection device, which includes a mixing tank 1. A threaded groove 12 is provided on the upper surface of the mixing tank 1 near the center. A threaded rod 31 is rotatably connected inside the threaded groove 12. A stirring component 2 is fixedly connected to the lower surface of the threaded rod 31.

[0036] The stirring component 2 includes a rotating assembly 21 fixedly connected to the threaded rod 31. The rotating assembly 21 includes a rotating disk 211 fixedly connected to the threaded rod 31. A layering assembly 22 is fixedly connected to the lower surface of the rotating disk 211. The layering assembly 22 includes a driven rod 220 fixedly connected to the rotating disk 211. A lifting component 225 is slidably connected to the bottom of the driven rod 220. Multiple scraping rods 224 are fixedly connected to the outer wall of the lifting component 225. A scraping plate 226 is rotatably connected to the end of the scraping rod 224. The scraping plate 226 is attached to the inside of the stirring tank 1, so that the scraping rod 224 moves upward to stir samples of different densities or viscosities. At the same time, when the scraping rod 224 reaches the bottom, the scraping plate 226 and the scraping rod 224 are on the horizontal plane. While rotating, it also prevents the sedimentation of samples and reaction liquids at the bottom, further increasing the stirring effect.

[0037] The outer wall of the rotating disk 211 has multiple rotating cavities 212. A rotating component 213 is rotatably connected inside the rotating cavity 212. A stirring blade 214 is fixedly connected to the other end of the rotating component 213. The stirring blade 214 on the outer wall of the rotating disk 211 rotates vertically through the rotating groove opened inside the rotating disk 211, so that the sample and the reaction liquid are fully stirred.

[0038] A connecting ring 221 is fixedly connected to the driven rod 220 near its upper end. A first rotating groove 222 is provided on the four sides of the outer wall of the connecting ring 221. A connecting rod 227 is rotatably connected inside the first rotating groove 222. A sliding groove 2241 is provided inside the scraping rod 224. A sliding rod 2242 is fixedly connected inside the sliding groove 2241. A sliding block 223 is slidably connected to the outer wall of the sliding rod 2242. The other end of the connecting rod 227 is rotatably connected to the top of the sliding block 223. The height between the connecting ring 221 and the scraping rod 224 is adjusted by using the connecting rod 227.

[0039] The scraper plate 226 has a second rotating groove 2261 at one end near the scraper rod 224. A rotating rod 2262 is fixedly connected inside the second rotating groove 2261. The scraper rod 224 is rotatably connected to the outer wall of the rotating rod 2262. The scraper plate 226 rotates at the end of the scraper rod 224 by rotating the rod 2262.

[0040] An elastic element 228 is fixedly connected to the bottom of the connecting ring 221 near the center. A lifting element 225 is fixedly connected to the other end of the elastic element 228. The elastic element 228 is located on the outer wall of the driven rod 220. The elastic element 228 is used to keep the lifting element 225 and the connecting ring 221 at the same height when not subjected to external force.

[0041] like Figure 2As shown, a positioning rod 34 is fixedly connected to one side of the upper surface of the mixing tank 1. A fixing plate 33 is fixedly connected to the top of the positioning rod 34. A lifting plate 32 is slidably connected to the positioning rod 34 near the center. A reverse motor 3 is fixedly connected to the upper surface of the lifting plate 32 near the other side. A threaded rod 31 is fixedly connected to the output end of the reverse motor 3. The motor drives the threaded rod 31 to rotate inside the threaded groove 12, so that the lifting plate 32 slides above the positioning column.

[0042] A feed hole 11 is provided on the upper surface of the mixing tank 1 near the other side, and a discharge hole 13 is provided at the bottom of the mixing tank 1 near the center. The sample and reaction liquid are fed through the feed hole 11, and the stirred sample is collected to the outside through the discharge hole 13.

[0043] In use, the motor drives the threaded rod 31 to rotate inside the threaded groove 12, which in turn drives the rotating disk 211 to rotate. At the same time, the stirring blades 214 on the outer wall of the rotating disk 211 rotate vertically through the rotating groove inside the rotating disk 211, so that the sample and the reaction liquid are fully stirred. As the threaded rod 31 continues to move downward, the scraper 226 is in contact with the inside of the stirring tank, so that the scraper 224 moves upward, so as to stir samples of different densities or viscosities differently. At the same time, when the scraper 224 reaches the bottom, the scraper 226 and the scraper 224 are on the horizontal plane, which prevents the sample and reaction liquid from settling at the bottom while rotating.

[0044] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
