Description

Technical Field

[0001] This utility model relates to the field of pesticide detection technology, and in particular to a pesticide detection device for fruits and vegetables. Background Technology

[0002] Pesticide residue testing in fruits and vegetables has become a crucial link in agricultural product quality control, market circulation supervision, and end-consumer protection. However, fruits and vegetables come in different forms, such as leafy vegetables (spinach, lettuce) and root vegetables (apples, cucumbers, potatoes). Both leafy and root vegetables require surface wiping and soaking for sampling. Traditional testing devices are usually designed for a single form, requiring separate configurations and different types of containers and equipment for different types of fruits and vegetables, such as leafy vegetables, melons, and root vegetables. This reduces the applicability of the testing devices, increases operating costs, and makes them less portable, reducing the flexibility of on-site testing and failing to meet diverse sampling needs. Utility Model Content

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4 This utility model discloses a pesticide detection device for fruits and vegetables, comprising: a detector 1, with a guide tube 8 disposed on the surface of the detector 1; a slide rail 2, fixed to the surface of the detector 1, and equipped with a mounting plate 3; a first storage cup 4 and a second storage cup 9, both disposed on the surface of the mounting plate 3, the second storage cup 9 being equipped with a crushing mechanism 10; two valves 11, each fixed to the lower end of the first storage cup 4 and the second storage cup 9 respectively; a flexible cover 13, disposed on the upper end of the first storage cup 4; and a spring 7, the upper and lower ends of the spring 7 being fixed to the surfaces of the flexible cover 13 and the mounting plate 3 respectively.

[0017] Detector 1 is a common enzyme inhibition method pesticide residue detector. Internally, it includes a light source module (usually an LED cold light source providing stable light at a specific wavelength); a colorimetric cell assembly for holding the sample solution after the reaction; a photoelectric detection module containing photodiodes or photomultiplier tubes to convert light signals into electrical signals; a microprocessor for instrument control and data processing; a temperature control module to maintain a stable temperature environment required for the reaction; and a data storage and display module containing a display screen, memory chip, and printer assembly. The pesticide content is determined by the fact that organophosphates and carbamates inhibit the activity of acetylcholinesterase. Under normal circumstances, this enzyme catalyzes the hydrolysis of acetylcholine, and the hydrolysis products react with a chromogenic agent to produce a yellow substance. The higher the pesticide concentration, the stronger the enzyme inhibition and the lighter the color. The inhibition rate is calculated by detecting changes in absorbance to determine whether the pesticide content exceeds the limit.

[0018] Storage cup 4 has a bucket-shaped structure and is rotatably connected to mounting plate 3. The installation method of storage cup 4 provides users with the conditions to rotate storage cup 4 to rub the surface of blocky fruits and vegetables.

[0019] Storage cup 9 is made of iron. Storage cup 9 is snapped into the mounting plate 3. The iron material of storage cup 9 ensures that the fruits and vegetables inside are crushed stably.

[0020] The flexible cover 13 consists of a silicone pad 5 and a reinforcing ring 6. The reinforcing ring 6 is fixedly connected to the silicone pad 5. The upper end of the spring 7 is fixedly connected to the reinforcing ring 6. The diameter of the silicone pad 5 is larger than the diameter of the first storage cup 4. The silicone pad 5 covers the mouth of the first storage cup 4. The flexible cover 13 is used to seal the first storage cup 4. At the same time, it utilizes the deformable characteristics of the silicone pad 5 and the downward pulling force of the spring 7 to fix block fruits and vegetables of different shapes.

[0021] A force-applying rod 12 is fixedly connected to the lower end of the No. 1 storage cup 4. The length of the force-applying rod 12 is greater than the combined width of the mounting plate 3 and the slide rail 2. The force-applying rod 12 is used to increase the force-bearing points of the No. 1 storage cup 4 and improve the convenience of rotating the No. 1 storage cup 4.

[0022] The lid of the second storage cup 9 is threadedly connected to the cup body. The power end of the crushing mechanism 10 is fixed to the lid. The connection between the lid and the cup body improves the stability of the second storage cup 9 after it is closed and increases the stability of the crushing mechanism 10 during operation.

[0023] The crushing mechanism 10 consists of a servo motor, a long rod fixed to the output end of the servo motor, and a blade fixed to the lower end of the long rod. The servo motor is fixed to the surface of the second storage cup 9. The servo motor uses the blade to crush the fruit and vegetable pieces put into the second storage cup 9.

[0024] Working principle: When the item to be tested is a leaf, the leaf is cut to a specified size and then pulled up by the flexible cover 13. The sample and extract are then added to the first storage cup 4 to achieve the purpose of soaking and sampling. When the item to be tested is a block, the extract is poured directly into the first storage cup 4, and then the item to be tested is placed into the first storage cup 4. The structure of the first storage cup 4 limits the contact area between the item and the extract. Then, the flexible cover 13 is pulled. When the spring 7 is deprived of external force, it automatically contracts and returns to its original position, thus applying a downward force to the flexible cover 13. The flexible cover 13 applies the downward force applied by the spring 7 to the item in the first storage cup 4, while the spring 7 fixes the pressure applied to the item, thus limiting the pressure on the item. At this time, the operator applies a rotational force to the first storage cup 4 through the force rod 12. The smooth inner wall of the first storage cup 4 rotates relative to the item, thereby rubbing the surface of the item to achieve the purpose of sampling.

[0025] When using the device, the guide tube 8 is fixed to the lower end of the first storage cup 4 by a socket. Therefore, when it is necessary to crush the sample, first press down the guide tube 8 to separate it from the first storage cup 4, then push the mounting plate 3 to the left to move the second storage cup 9 above the guide tube 8, then push the guide tube 8 up to fix it to the lower end of the second storage cup 9, and then put the sample and extract into the second storage cup 9. The crushing mechanism 10 can then be used to process the sample to be tested.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
