[0020] This utility model provides, for example Figure 1 The reagent addition device for drug testing shown includes a fixing mechanism 1, and further includes: The adjusting mechanism 2 and the feeding mechanism 3 are located outside the fixed mechanism 1.

[0021] To facilitate the addition of reagents to multiple sample beakers, such as Figure 1-2 and Figure 4-5 As shown, the adjustment mechanism 2 includes two fixed frames 205. A controller 206 is fixedly mounted on the outer wall of one end of one fixed frame 205, and a placement plate 207 for placing reagent bottles is fixedly mounted on the outer wall of one end of the other fixed frame 205. Fixed toothed plates 211 are provided on the top inner sides of both fixed frames 205. The feeding mechanism 3 includes a mounting base 301, which is movably sleeved on the outside of the fixed toothed plate 211. A movable gear 302 is rotatably mounted on the inner top of the mounting base 301, meshing with the fixed toothed plate 211. A fixed plate 304 is fixedly mounted on the bottom of the mounting base 301, and a liquid storage tank 305 is mounted on the bottom inner side of the fixed plate 304. A fixed plate 304 is fixedly mounted on the bottom of the liquid storage tank 305. The dropper 306 is connected to the inlet flange of the storage tank 305 by a telescopic hose 307. The end flange of the telescopic hose 307 away from the storage tank 305 is connected to an outlet pipe 308, which is inserted into the inside of the reagent bottle. The placement plate 207 can place the reagent bottle. The reagent can be transported into the storage tank 305 through the outlet pipe 308 and the telescopic hose 307. Under the meshing action between the movable gear 302 and the fixed gear plate 211, the storage tank 305 and the dropper 306 can be moved laterally, so that the dropper 306 can add reagents to multiple sample beakers laterally. At the same time, the adjustment mechanism 2 can adjust the longitudinal position and height of the dropper 306.

[0022] To facilitate the adjustment of the longitudinal position of the dispensing dropper 306, as shown in 1-4, the fixing mechanism 1 includes a fixed base plate 101. Multiple placement slots 102 are evenly spaced on the top of the fixed base plate 101, and these slots are located on the outside of the sample beaker. Mounting slots 103 are provided on the outer walls of both ends of the fixed base plate 101. A servo motor 204 is fixedly mounted on one side of the outer wall of the fixed base plate 101. Adjusting screws 201 are rotatably mounted on the inner walls of both mounting slots 103. The outer sides of the two adjusting screws 201 are threadedly connected to the bottom inner walls of adjacent fixing frames 205. Movable slots 208 are provided on the top inner walls of both fixing frames 205. One side of the outer wall of each adjusting screw 201 is fixedly sleeved with… There are synchronous pulleys 202, and synchronous belts 203 are installed on the outer sides of the two synchronous pulleys 202. The servo motor 204 is connected to the adjacent adjusting screw 201 through the output shaft. Multiple sample beakers can be placed through multiple placement slots 102. The mounting slots 103 can be used to install and fix the adjusting screws 201. The controller 206 causes the servo motor 204 to drive one of the adjusting screws 201 to rotate. Through the transmission action of the synchronous pulleys 202 and synchronous belts 203, the other adjusting screw 201 rotates synchronously, which can drive the two fixing frames 205 to move along the inner wall of the adjacent mounting slots 103, thereby adjusting the longitudinal position of the dispensing dropper 306.

[0023] To facilitate the adjustment of the height of the feeding dropper 306, such as Figure 2 and Figure 4-5 As shown, hydraulic cylinders 209 are fixedly installed on the top of both fixed frames 205. The piston rods of the two hydraulic cylinders 209 penetrate the inner wall of the top of the adjacent movable grooves 208 and are fixedly installed with movable seats 210. The two movable seats 210 are slidably connected to the inner wall of the adjacent movable grooves 208 respectively. The outer walls of both ends of the fixed toothed plate 211 are fixedly connected to the two movable seats 210 respectively. A drive motor 303 is fixedly installed on the top of the outer wall of one side of the mounting base 301. The drive motor 303 is connected to the movable gear 302 through an output shaft. The controller 206 makes the two hydraulic cylinders 209 work, which can drive the two movable seats 210 to move along the inner wall of the adjacent movable grooves 208, thereby driving the fixed toothed plate 211 to move up and down inside the two fixed frames 205, thereby adjusting the height of the feeding drip tube 306.

[0024] When adding reagents to sample beakers, multiple sample beakers are placed in multiple placement slots 102, and reagent bottles are placed on top of placement plate 207. Dispensing pipes 308 are then inserted into the reagent bottles. Controller 206 enables the dispensing pipes 308 and telescopic hoses 307 to transport the reagents from the reagent bottles to the storage tank 305. Simultaneously, controller 206 controls the dispensing pipe 306 to drip reagents into the sample beakers below. Then, controller 206 causes drive motor 303 to drive movable gear 302 to rotate. Through the meshing between movable gear 302 and fixed toothed plate 211, mounting base 301 moves laterally outside the fixed toothed plate 211, thereby adjusting the lateral position of dispensing pipe 306. Simultaneously, controller 206 causes servo motor 204 to drive one of the adjusting screws. When 201 rotates, the synchronous pulley 202 and synchronous belt 203 drive another adjusting screw 201 to rotate synchronously, thereby causing the two fixed brackets 205 to move longitudinally along the inner wall of the adjacent mounting groove 103. This allows for adjustment of the longitudinal position of the dispensing dropper 306. The controller 206 controls the two hydraulic cylinders 209 to work, which can drive the two movable seats 210 to move along the inner wall of the adjacent movable groove 208. This can also drive the fixed toothed plate 211 to move up and down, allowing for adjustment of the height of the dispensing dropper 306. This allows for convenient addition of reagents to multiple different sample beakers, while avoiding splashing during reagent addition, thus improving the efficiency of drug detection. This embodiment specifically solves the problem of low drug detection efficiency caused by the inability to conveniently add reagents to multiple different samples in the prior art.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
