[0016] 5) Gear I is meshed with gear II. Some positions of gear I and gear II are not provided with tooth top grooves. When the positions of gear I and gear II without tooth top grooves coincide, gear II is no longer meshed and gear I stops rotating. When the positioning column at the bottom of gear I rotates with gear I, the positioning column contacts the toggle plate at the bottom of gear II, the positioning column drives the toggle plate, and the toggle plate drives gear II to rotate. The rotation of gear II causes gear I to mesh with gear II again, and gear II rotates with gear I, thereby achieving the purpose of intermittent rotation, driving the rotating support plate to rotate intermittently, and completing the food collection and detection process in the rotation gap, saving time and improving detection efficiency.

When the sampling container 306 containing the food to be tested rotates to the lower part of the detection instrument 304, the electric push rod III 303 pushes the detection instrument 304 downward in the rotation gap to complete the food detection. After the detection is completed, the electric push rod III 303 drives the detection instrument 304 to reset, and the sampling container 306 rotates with the rotating support plate 305 to detect the food to be tested in turn.

[0035] A solid-liquid separation sampling device for food safety testing, the working process is as follows:

[0036] The food to be tested is fed into the squeezing box 110 from the feed port 11, and the hydraulic cylinder I 101 pushes the lower pressure plate 102 downward to squeeze the food to be tested in the squeezing box 110. The moisture in the food passes through the filter plate 103 and is discharged from the filtrate outlet 111. After the lower pressure plate 102 moves up and resets, the hydraulic cylinder II 106 pushes the push plate 104 to push the push plate 104 into the squeezing box 110 from an opening on one side. The electric push rod I 107 drives the baffle I 108 to move up along the chute direction of the limiting chute 109 on both sides to open the opening.

[0037] After the squeezed food is pushed onto the filter conveyor belt 203, the motor I 201 drives the filter conveyor belt 203 to rotate through the transmission shaft 202, and the squeezed food on the filter conveyor belt 203 is transported downward. The residual liquid in the food passes through the filter conveyor belt 203 by gravity and flows downward into the filtrate collection box 15. The electric push rod II 213 pushes the connecting plate 214, and the connecting plate 214 connects the baffle II 204 and the baffle III 205 to adjust the position of the baffle II 204 and the baffle III 205. The motor V 215 controls the two sets of crushing rollers 216 at the bottom of the connecting plate 214 to crush the food. The food that passes through is crushed. The motor IV 212 drives the connecting rod III 210 to rotate. The connecting rod III 210 drives the connecting rod I 208 and the connecting rod II 209 to rotate. The connecting rod I 208 and the connecting rod II 209 connect the two sets of baffles III 205 to adjust the opening and closing size of the two sets of baffles III 205. The motor II 207 controls the rotation of the baffle IV 206. The position between the baffles is controlled by the electric push rod II 213, the motor IV 212, and the motor II 207 to ensure that the food on the filter conveyor belt 203 is crushed by the crushing roller 216. After the movement trajectory of the food is controlled, it enters the subsequent detection process.

[0038] 310 and gear Ⅱ310 rotate. The support plate 305 rotates, and the sampling container 306 is set on the rotating support plate 305 and rotates together with the rotating support plate 305. When the sampling container 306 is in place, the motor II 207 controls the baffle IV 206 to rotate in the gap when the rotating support plate 305 rotates, so that the food to be tested on the filter conveyor belt 203 is transported to the sampling container 306. When the rotating support plate 305 rotates, the motor II 207 controls the baffle IV 206 to rotate so that the two groups of baffles IV 206 cooperate to prevent the food on the filter conveyor belt 203 from falling. The sampling container 306 rotates with the rotating support plate 305. When the sampling container 306 containing the food to be tested rotates to the lower part of the detection instrument 304, the electric push rod III 303 pushes the detection instrument 304 downward in the rotation gap to complete the food detection. After the detection is completed, the electric push rod III 303 drives the detection instrument 304 to reset, and the sampling container 306 rotates with the rotating support plate 305 to detect the food to be tested in turn.
