When a vegetable sample is sent into the grinding mechanism 9, the electric push rod I91 is started to drive the pressing plate 912 and the rotary cutter head 914 to move downwards, the rotary cutter head 914 and the blade 918 are connected through the torsion spring 917, the blade 918 is in the shape of a fan blade, air flow can be formed when the rotary cutter head is rotated, air below the rotary cutter head is discharged upwards, an air hole 919 is formed in the blade 918, the blade 918 is communicated with the connector 920 arranged on the rotary cutter head 914 through the air pipe 921, the bottom of the connector 920 is rotationally connected with the elastic hose 4, the electric push rod II 910 drives the pressing plate 912, the pressing plate 912 is always positioned above the rotary cutter head 914, the rotary cutter head 914 is driven to rotate through the motor I99, the blade 918 on the rotary cutter head 914 is thrown out due to centrifugal force, the vegetable sample is continuously cut, the nitrogen pump 2 conveys low-temperature nitrogen into the blade 918 through the elastic hose 4 and the air pipe 921 due to the fan-shaped of the blade 918 itself, when in rotation, air with oxygen below is upwards discharged, low-temperature nitrogen is sprayed through the air holes 919, vegetable residues and vegetable juice are always in a low-temperature anaerobic environment in the cutting process, vegetable residues are not easily attached to the blade 918 under the action of nitrogen air flow, vegetable samples are cut into residues after a period of time, the electric push rod II 910 controls the pressing plate 912 to press down, a part of the rotary cutter head 914 is contacted with the buffering cotton 913 on the pressing plate 912, the rotary cutter head 914 is rapidly stopped rotating, at the moment, the blade 918 is recycled into the rotary cutter head 914 under the action of the torsion spring 917, the electric push rod II 910 controls the pressing plate 912 to press down, the bottom surface of the rotary cutter head 914 and the bottom surface of the pressing plate 912 are positioned at the same level, the electric push rod I91 controls the rotary cutter head 914 and the pressing plate 912 to press down together, sample residues are extruded out of juice, and the sample residues enter the collecting cavity 131 through the filter plate 915 and the funnel 96, and then the second electric door 94 is opened, the scraping plate 916 pushes the waste residues on the filter plate 915 into the waste residue collecting box 95 through the first electric sliding rail 97, and the waste residue collecting box 95 is connected with the second shell 92 through a sliding groove, so that the treatment after detection is convenient.
The bottom of the reaction chamber 134 and the collection chamber 131 of the liquid collection portion 13 are made of magnetic materials, the outer shell of the reaction chamber 134 is made of transparent materials, the liquid collection portion 13 is fixed on the conveying portion 14 through the electromagnetic base 141, after the liquid is collected, the liquid collection portion 13 is conveyed to the position right below the second electric slide rail 15 through the third motor 144, the connecting rod 142 and the rotating shaft 143 in the conveying portion 14, at the moment, the electromagnetic base 141 is powered off, the electromagnetic slide block 8 is powered on, the liquid collection portion 13 is fixed on the electromagnetic slide block 8, and therefore the collection chamber is sealed, and 10ml of vegetable juice is conveyed into the reaction chamber 134 through the constant-current valve 133 to react with the acidic iodine liquid in the conveying process. Before the liquid collecting parts 13 are sent to the observation glass 6 through the second electric slide rail 15, whether the vitamin C content in the vegetable sample reaches the standard is judged by observing whether the iodine solution completely fades. After the liquid collecting part 13 is kept stand for a period of time, the excessive vegetable juice in the collecting cavity 131 is slowly separated to form supernatant, and the supernatant can be used for detecting the nitrite content and the pesticide residue content in the vegetable sample later.
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
