[0027] Specifically, when the chemicals enter the second empty bin 9, the second motor 23 is started, and its first transmission shaft 21 drives the crushing plate 20 to rotate at high speed on the inner wall of the second empty bin 9. A crushing roller 22 is installed on the inner wall of the second empty bin 9. When the large granular chemicals pass through the crushing roller 22, they are squeezed by the outer surface of the crushing plate 20 to achieve a crushing effect. After the chemicals are crushed, they enter the hollow tube 5, and the auger 29 driven by the first motor 6 transmits them to the end of the hollow tube 5. Since the opening of the cover shell 4 faces downward, all the chemicals are introduced into the first empty bin 3 for mixing and stirring. The third motor 33 is started, and its second transmission shaft 32 drives the stirring rod 31 to rotate at high speed on the inner wall of the first empty bin 3. The evenly mixed finished product flows out through the discharge port 34 for collection.

[0029] Specifically, the switch structure is composed of a spring 26, a round tube 25, a partition 24 and a third buckle 27. The crushed chemicals enter the hollow tube 5 through the partition 24. The third buckle 27 is movable to control the partition 24 to move downward, while the spring 26 controls the partition 24 to rise, forming a switch assembly. The outer wall of the first empty bin 3 is connected to the L-shaped tube 13. The top of the L-shaped tube 13 is connected to the cylinder 15 filled with chemical solvents and the hydraulic rod 19 responsible for squeezing the chemical solvent container to avoid damage caused by improper human operation. The upper surface of the second empty bin 9 is provided with a bin cover 10. The bin cover 10 is controlled by the first buckle 11 and the second buckle 12 to improve the sealing of the chemicals during crushing and ensure the safety of the operators.

[0030] Reference Figure 4-Figure 6 The spring 26 is slidably connected to the round tube 25, the round tube 25 is fixedly connected to the second empty chamber 9, the outer wall of the pulley 18 is rotatably connected to the piston rod 17, the lower surface of the piston rod 17 is fixedly connected to the piston 16, the inner wall of the cylinder body 15 is slidably connected to the screen 30, the upper surface of the bottom plate 2 is fixedly connected to the first bracket 7, the upper surface of the bottom plate 2 is fixedly connected to the second bracket 8, the outer wall of the first motor 6 is fixedly connected to the first bracket 7, the lower surface of the hollow tube 5 is fixedly connected to the second bracket 8, and the lower surface of the bottom plate 2 is fixedly connected to the support column 1.

[0031] Specifically, the round tube 25 is fixed in the inner wall of the second empty bin 9 to ensure that its spring 26 is not corroded by the chemicals and can work normally. The output end of the hydraulic rod 19 is fixedly connected to the pulley 18, which can easily rotate the piston rod 17 to open the cylinder body 15. There is a screen 30 at the bottom of the cylinder body 15 to prevent the debris generated when the chemical reagent bottle is broken from entering the first empty bin 3 through the L-shaped tube 13 and affecting its stirring. The first motor 6 and the hollow tube 5 are supported by the first bracket 7 and the second bracket 8 to improve the stability of the device during operation. The design of the discharge port 34 facilitates the collection of mixed chemicals. The bottom plate 2 provides a platform for the entire device structure, and a number of support columns 1 are fixed under the bottom plate 2 for reinforcement and support.

[0032] Working principle: first open the bin cover 10 on the top of the second empty bin 9, put in the chemicals, close the bin cover 10, and then the output end of the second motor 23 drives the first transmission shaft 21. Under the action of the first transmission shaft 21, the crushing plate 20 inside the second empty bin 9 starts to rotate at high speed, and the large granular chemicals are squeezed into powder by the double squeezing of the crushing roller 22 and the crushing plate 20 in the second empty bin 9. After completion, the partition 24 connected by the third buckle 27 will open under the influence of its gravity, and the chemicals loaded in the second empty bin 9 will enter the hollow tube 5 in batches, but under the action of the spring 26, the partition 24 will close again, and the first motor 6 placed on the first bracket 7 will start, and the output end of the first motor 6 will drive the auger 29 to move, and the first motor 6 will control the auger 29 to transport the crushed chemicals to the end of the hollow tube 5, and then After that, the rotation stops. Since a hollow cover 4 is provided at the end of the hollow tube 5, the chemicals without support will fall into the first empty bin 3. At this time, the piston rod 17 is rotated to open the cylinder 15 fixed on the base 14, and an equal proportion of chemical solvent is put in. The piston rod 17 is rotated again to close the piston 16 above the cylinder 15. The hydraulic rod 19 will contract, and the air pressure generated will push the piston 16 to pump the chemical solvent into the L-shaped tube 13, and then into the first empty bin 3. The crushed chemicals will be mixed with the chemical solvent here. At this time, the third motor 33 installed at the bottom of the first empty bin 3 will start, and its output end will drive the stirring rod 31 on the second transmission shaft 32 to rotate at a high speed to make the mixing more sufficient and uniform. After the stirring is completed, the chemical mixture will flow out through the discharge port 34 and be collected by a container.
