Description

Technical Field

[0001] The utility model belongs to the technical field of trace element detection, and particularly relates to a turnip leaf trace element detection device. Background Art

[0002] Turnip is a biennial herbaceous plant of the genus Brassica in the family Cruciferae. Its fleshy tubers vary in shape, including spherical, oblate, or oblong. The skin of turnips is typically white, yellow, or red. Its leaves are green and varied in shape, some with pinnate lobes. Turnips have considerable nutritional value, and both their tubers and young leaves are edible. They have unique applications in culinary cultures around the world and also play an important role in agricultural cultivation.

[0003] At present, turnip leaves contain a variety of trace elements, such as iron, zinc, manganese, copper, etc. Iron plays a key role in the enzyme system related to photosynthesis and respiration of plants; zinc participates in the activity regulation of multiple enzymes, which helps to maintain the normal physiological metabolism of leaves. Manganese is important for the release of oxygen in photosynthesis and the antioxidant enzyme system, and can enhance the stress resistance of leaves. Copper is indispensable in processes such as electron transfer. The presence of these trace elements gives turnip leaves many benefits. From the perspective of human health, when people eat turnip leaves containing these trace elements, these trace elements can participate in the physiological metabolic process of the human body. For example, iron helps in the synthesis of hemoglobin, zinc can enhance human immunity, manganese is beneficial to bone development, etc., and copper has a certain maintenance effect on the normal function of the cardiovascular system. From the perspective of the plant itself, these trace elements help turnip leaves to better photosynthesize, resist pests and diseases, and adapt to different environmental conditions.

[0004] During the application process, turnips usually need to be supplemented with trace elements contained in their leaves for detection. In the existing trace element detection process, detection equipment is usually used for detection. For example, the Chinese patent with the announcement number "CN216485000U" discloses a device for detecting multiple nutrient elements in vegetable seedling growth, which involves the field of nutrient element detection technology. In order to solve the problem that when the corresponding detection sensor is buried in the soil, the detection method becomes more difficult to detect nutrient elements when the soil moisture decreases, and the measured nutrient element data is not accurate, and the detection effect is not good. A cover is provided above the main body of the device, a soil crushing bin is provided inside the main body of the device, a stirrer is provided above the cover, a stirring blade is provided inside the soil crushing bin, a drainage pipe is provided at the lower end of the soil crushing bin, a filter is provided at the bottom of the soil crushing bin, and the filter is provided above the drainage pipe, a storage chamber is provided on the main body of the device, a drawer is provided on one side of the main body of the device, a water frame is provided at the upper end of the drawer, a detection sensor is provided below the water frame, and one end of the detection sensor extends into the interior of the water frame;

[0005] During the use of the above-mentioned detection equipment, a motor-driven stirring blade is used to crush the sample and prepare the solution for auxiliary detection. However, its pretreatment stirring structure has poor processing efficiency. During the processing of different samples, it is usually impossible to process multiple samples at one time. Obviously, sample processing is relatively time-consuming. Only after one sample is tested can another sample be pretreated, and then the test can be carried out again after the pretreatment is completed. It can be seen that the whole cannot use the time gap of the test for pretreatment. The pretreatment during the overall use is relatively time-consuming. The overall use has certain defects and shortcomings, so it needs to be improved. Utility Model Content

[0006] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a device for detecting trace elements in turnip leaves to solve the problems raised in the background technology.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A turnip leaf trace element detection device comprises a base plate, a mass spectrometer fixedly mounted on the top of the base plate, an injector fixedly mounted on the upper back end of the mass spectrometer, a main shaft fixedly mounted on the upper back end of the mass spectrometer, a pretreatment mechanism rotatably connected to the back end of the main shaft, a power mechanism fixedly mounted on the upper back end of the mass spectrometer, the power mechanism being used to drive the pretreatment mechanism;

Branch pipes are fixedly installed on the outer side of the inner ring at equal intervals. The outer end of the branch pipe is fixedly installed with an outer ring. The front of the outer ring is rotatably connected with processing components arranged in a ring shape at equal intervals. The bottom output end of the processing component at the uppermost end is set directly above the input end of the sample injector.

[0011] As an optimal technical solution, the processing component includes a rotating shaft, which is arranged in a ring shape with equal intervals and installed on the side of the outer ring close to the mass spectrometer. A processing tank is fixedly installed at the front end of the rotating shaft, and a sealing cover is provided on the top of the processing tank. A second motor is fixedly installed on the top of the sealing cover. The output end of the second motor passes through the sealing cover and is fixedly installed with a vertical shaft. The upper end of the outer surface of the vertical shaft is fixedly connected with a mincing blade at equal intervals. An electromagnetic valve is fixedly installed at the bottom of the processing tank, and the electromagnetic valve at the top is arranged directly above the input end of the injector.

[0012] As an optimal technical solution, weight-bearing balls are fixedly installed on both sides of the bottom of the processing tank, and the mincing blades are arranged in an inclined shape as a whole.

[0013] As a preferred technical solution, an auger is fixedly mounted on the lower end of the outer surface of the vertical shaft, and the overall shape of the bottom of the processing tank and the auger are both set to be conical.

Because the gear meshes with the gear ring, it drives the inner ring, straight tube and outer ring to rotate, thereby causing the processing tank to rotate alternately. The processing tank is connected to the outer ring via a rotating shaft. A weighted ball at the bottom makes it heavier. When moving, it will adaptively rotate to remain perpendicular to the ground. This allows the position of the processing tank to be flexibly adjusted to the top of the sample injector. The solenoid valve is opened to add sample solution.

[0018] Second, during pre-treatment, the processing component of the device puts the solution and sample into the processing tank and then starts the second motor. The second motor drives the vertical shaft to rotate, so that the mincing blade cuts and crushes the turnip leaves. When the leaves settle to the bottom of the tank, the vertical shaft drives the auger to make the leaves roll upward and continue to be chopped. The mincing blade is tilted and can be guided to improve the crushing effect. The bottom of the processing tank is conical, which helps the solution to be quickly discharged into the sampler. If cleaning is required during use, the mounting screw can be loosened to remove the fixing plate and sealing cover, and the vertical shaft, mincing blade and auger can be pulled out, which improves the convenience of detection.

The output end of the first motor 63 is fixedly mounted with a gear 64. The gear 64 and the gear ring 62 are meshed and connected.

The first motor 63 meshes with the gear ring 62 through the gear 64 at the output end. This design can accurately transmit the power of the motor, and the gear 64 is driven by the motor to rotate, thereby driving the gear ring 62 and the inner ring 31 connected thereto to move, thereby driving the pretreatment mechanism 3 to work. This power transmission method is simple, efficient, and easy to control, which can ensure the stable operation of the pretreatment mechanism 3 and provide reliable power guarantee for the detection of trace elements in turnip leaves.

[0029] refer to Figure 1-Figure 4The processing assembly 34 includes a rotating shaft 341, which is arranged in a ring shape at equal intervals and is installed on the side of the outer ring 33 close to the mass spectrometer 2. A processing tank 342 is fixedly installed at the front end of the rotating shaft 341. A sealing cover 311 is provided on the top of the processing tank 342. A second motor 343 is fixedly installed on the top of the sealing cover 311. The output end of the second motor 343 passes through the sealing cover 311 and is fixedly installed with a vertical shaft 344. The upper end of the outer surface of the vertical shaft 344 is fixedly connected with a mincing blade 345 at equal intervals. The bottom of the processing tank 342 is fixedly installed with an electromagnetic The solenoid valve 346 at the top is set just above the input end of the sample injector 5. The bottom of the processing tank 342 is fixedly installed with a weighted ball 347 on both sides. The mincing blade 345 is set in an inclined shape. The lower end of the outer surface of the vertical shaft 344 is fixedly installed with an auger 348. The overall shape of the bottom of the processing tank 342 and the auger 348 is set to be conical. The bottom of the sealing cover 311 is fixedly installed with a fixing plate 349 on both sides. The lower end of the fixing plate 349 is threadedly connected to the mounting screw 3410. The mounting screw 3410 It is set as a hand-tightened screw, and the outer surface of the knob at the outer end of the mounting screw 3410 is fixedly connected with anti-slip protrusions at equal intervals. The inner ring 31 is set as a conductive slip ring, and the internal of the branch pipe 32 hides the wire. Each second motor 343 is electrically connected to the inner ring 31 through the wire. The rotating shaft 341 and the processing tank 342 arranged in an equidistant ring have a reasonable structure and can process multiple samples at the same time. The second motor 343 on the top of the sealing cover 311 drives the vertical shaft 344 to work. The mincing blade 345 on the vertical shaft 344 can mince the sample, and its inclined setting It can efficiently crush and guide samples. The auger 348 can make the samples deposited at the bottom roll and be continuously crushed. The conical bottom of the processing tank 342 and the auger 348 are conducive to sample aggregation and processing. The solenoid valve 346 can conveniently control the sample to enter the sample injector 5. The weighted ball 347 keeps the processing tank 342 stable. The sealing cover 311 is connected to the mounting screw 3410 through the fixing plate 349. It has a hand-tightening design and anti-slip protrusions for easy disassembly and cleaning. The second motors 343 are connected to each other through conductive slip rings and wires to achieve stable power supply and signal transmission.

[0030] Principle of use and advantages: When the device is actually used, different samples and corresponding solutions can be added to each processing tank 342 for processing. During the processing, the first motor 63 is started. After the first motor 63 starts running, it will drive the gear 64 to rotate. Since the gear 64 and the gear ring 62 are meshed with each other, the rotation of the gear 64 can assist in driving the inner ring 31, and then drive the straight tube and the outer ring 33 to rotate together. The rotation of the outer ring 33 can assist in driving each processing tank 342 to rotate alternately. It should be noted here that each processing tank 342 is connected to the outer ring 33 through the rotating shaft 341 and can rotate on the outer ring 33. In addition, a weighted ball 347 is installed at the bottom of the processing tank 342, which makes the bottom of the processing tank 342 relatively heavy. When the processing tank 342 As the outer ring 33 moves, the processing tank 342 will automatically and adaptively rotate on the outer ring 33 under the influence of gravity, thereby ensuring that the processing tank 342 can always remain vertical to the ground during the rotation of the outer ring 33. In this way, we can flexibly adjust the position of each processing tank 342 to move them to the top of the sampler 5, and then open the solenoid valve 346 at the bottom of the processing tank 342, and the sample solution can be smoothly added to the inside of the sampler 5. It can be seen that during the processing process, the device can process multiple different samples at a time, and can also flexibly adjust the position of each processing tank 342, and can realize continuous and uninterrupted pretreatment work in the detection interval, saving the time required for pretreatment, and effectively improving the detection efficiency of the mass spectrometer 2 for turnip leaves.

[0031] By setting up the processing component 34, the device can put the solution and sample into the processing tank 342 during pre-treatment, and then start the second motor 343. The operation of the second motor 343 will drive the vertical shaft 344 to start rotating. As the vertical shaft 344 rotates, it will drive the mincing blade 345 to rotate together. The rotation of the mincing blade 345 can cut and crush the turnip leaves in the solution. When the cut turnip leaves are deposited at the bottom of the processing tank 342, the vertical shaft 344 will drive the auger 348 to rotate, causing the turnip leaves to roll upwards, so that the turnip leaves can be continuously chopped by the mincing blade 345, and the mincing blade 345 is set at an angle. This design can guide the turnip leaves, causing them to roll up and down, thereby further improving the cutting and crushing effect. In addition, the bottom of the processing tank 342 is conical. This shape can play an auxiliary guiding role, which is conducive to the rapid discharge of the solution into the injector 5. During use, if it needs to be disassembled for cleaning, it is only necessary to loosen the mounting screw 3410 to remove the fixing plate 349 and the sealing cover 311 on its top, and then the vertical shaft 344 and the mincing blade 345 and the auger 348 thereon can be pulled out together, which is very convenient for cleaning the processing component 34 and further improves the detection convenience of the device during use.
