[0029] A plurality of barrels 9 are provided above the center of the first preparation tank 6 and the second preparation tank 7 in the body 1. Different detection reagents are stored in the barrels 9. The bottom ends of the plurality of barrels 9 are connected to two-way valves. The two outlets of the two-way valves are connected to hoses. The two hoses are respectively connected to the side walls of a preparation tank, and the connecting part between the hose and the first preparation tank is located below the filter 10;

[0030] The first mixing tank 6 and the second mixing tank 7 are both provided with a hemispherical cover at the bottom axis, and a second motor is provided in the cover. The output shaft of the second motor passes through the cover and a plurality of 7-shaped stirring rods 15 are arranged in a circular array.

The bottom wall of the first mixing tank 6 and the second mixing tank 7 are both provided with a plurality of material pipes 16 on the side of the cover.

[0031] A material taking chamber and a water storage chamber 13 are arranged from top to bottom in the machine body 1 below the two preparation tanks. The sewage pipe 11 is connected to the water storage chamber 13. The bottom wall of the water storage chamber 13 is conical. A sewage outlet is arranged on the side wall at the lowest end of the water storage chamber 13. The material taking chamber is located directly below the two preparation tanks and is provided with two open ports 12. The material pipes 16 on the first mixing tank 6 and the second mixing tank 7 are respectively inserted into the corresponding ports 12. The bottom walls of the two ports 12 are both mesh plates 14.

[0032] In this embodiment, electric valves are provided in the material pipe 16, the hose, the delivery pipe 5, and the sewage outlet to control the flow direction of the liquid.

[0033] In this embodiment, the outer ends of the feeding tube 3 and the insertion tube 8 are threadedly installed with sealing covers. When not in use, the feeding tube 3 and the insertion tube 8 are closed to prevent dust from falling into the second preparation tank 7 and the grinding dish 2 and affecting the detection results.

[0034] In this embodiment, a water tank is suspended outside the body 1, and an electric valve is also provided at the water outlet of the water tank. A controller is provided inside the body 1, and a display screen is provided on the outer wall of the body 1. The controller can automatically control the opening of all electric valves.

[0035] In this embodiment, the front shell of the body 1 is detachable, which is convenient for maintenance and replacement as well as replenishment of the detection reagent in the barrel 9.

[0036] The specific use process of this program:

[0037] First, the sample and clean water are respectively fed into the grinding dish 2 and the second mixing tank 7 through the feeding pipe 3 and the insertion tube 8, and the driving device is started to drive the grinding pestle 4 to swing continuously in the grinding dish 2 to grind the sample such as rice. After the sample is ground into powder, clean water is injected into the grinding dish 2 to soak the powder. After soaking for a certain period of time, the electric valve of the delivery pipe 5 is opened to flow the solution mixed with the sample powder in the grinding dish 2 into the first mixing tank 6. The solution is first filtered through the filter screen 10, and the powder flows down along the inclined surface of the filter screen 10 and enters the water storage chamber 13 from the sewage pipe 11;

[0038] After the solution is filtered, the two openings of the two-way valve on the hose are opened alternately, so that the detection reagent in the barrel 9 is injected into the first mixing tank 6 and the second mixing tank 7, and then the two second motors are both started, thereby controlling the stirring rod 15 to start, so that the filtered solution and the detection reagent in the first mixing tank 6, and the clean water and the detection reagent in the second mixing tank 7 are evenly mixed. After the mixing is completed, the second motor is turned off;

[0039] The test tubes are placed in the port 12 and aligned with the material tube 16. The electric valve in the material tube 16 is opened, so that the solutions in the two mixing tanks flow into the corresponding test tubes. The test tubes are then placed in the additive detector to detect illegal additives.

[0040] After the inspection is completed, all electric valves are opened, and clean water is injected from the feeding pipe 3 and the insert pipe 8 respectively to flush the grinding dish 2 and the second mixing tank 7. The clean water in the grinding dish 2 flows into the first mixing tank 6 along the conveying pipe 5, which not only cleans the first mixing tank 6, but also flushes the filter screen 10, and the powder remaining on the filter screen 10 flows into the water storage chamber 13 from the sewage pipe 11. In the cleaning process, the driving device and the stirring rod 15 can also be started synchronously to stir the clean water to improve the cleaning effect. The water in the first mixing tank 6 and the second mixing tank 7 drips from the barrel 9, and then flows into the water storage chamber 13 below from the mesh plate 14. The sewage in the water storage chamber 13 can be discharged from the sewage outlet, thereby completing the cleaning operation.

[0041] During the whole detection process, only the sample needs to be manually put into the grinding dish 2, and the rest is performed automatically, which reduces manual participation, thereby greatly reducing the manpower burden, and the automation greatly improves the detection preparation rate.

[0042] Preferably, a warning light is provided at the port 12. When the test solution is prepared, the warning light flashes to warn the operator, who then takes out the test tube and places it into the test equipment to perform the test operation.

[0043] Embodiment 2, the driving device includes a suspension plate fixed on the cover, a first motor is fixed on the suspension plate, a crank 17 is fixed on the output shaft of the first motor, a rocker 18 is universally mounted on the end of the crank 17, a ring is universally mounted on the other end of the rocker 18, the ring is universally connected to the upper end of the grinding pestle 4, the first motor starts to drive the crank 17 to rotate, and the crank 17 drives the grinding pestle 4 to swing continuously through the rocker 18, thereby realizing the grinding operation.

[0044] Embodiment 3, the electric valve in the delivery pipe 5 includes an electric telescopic rod 19 fixed in the body 1, a curved pipe 20 is fixed to the protruding end of the electric telescopic rod 19, a piston 21 is fixed to the end of the curved pipe 20, the piston 21 is inserted into the delivery pipe 5, the upper part of the inner wall of the delivery pipe 5 is circular, and the lower part is conical, so that the piston 21 moves downward, and a gap is formed between the side wall of the piston 21 and the inner wall of the delivery pipe 5, the solution in the grinding dish 2 will seep down, and the piston 21 moves upward to close the delivery pipe 5; preferably, an arc-shaped grinding layer is provided on the upper end of the piston 21, the grinding layer closes the upper end of the delivery pipe 5 and forms a complete hemispherical inner wall with the inner wall of the grinding dish 2, erasing the gap, thereby preventing sample particles such as rice from falling into the gap and being unable to be ground, ensuring that all samples can be ground by the grinding pestle 4, and at the same time preventing the surface of the piston 21 from being too soft. During grinding, the sample is concave on the surface of the piston 21 and cannot be ground.
