Description

Technical Field

[0001] The utility model relates to the technical field of agricultural product processing and detection, in particular to an integrated instrument for agricultural product pretreatment and pesticide residue detection. Background Art

[0002] Current technology often requires the use of immersion boxes when conducting pesticide residue testing. Using the immersion box to soak agricultural products can provide preliminary cleaning of the agricultural products and achieve pretreatment of the agricultural products. At the same time, it can also dissolve the pesticide components on the surface of the agricultural products in the water. During subsequent testing, the testers only need to use a pesticide detector to detect the water after soaking.

[0003] A Chinese utility model patent with announcement number CN220418955U discloses a pretreatment device for detecting pesticide residues in agricultural products, belonging to the field of agricultural product pretreatment technology. A pretreatment device for detecting pesticide residues in agricultural products includes a soaking tank and a drainage pipe, as well as a water filter plate, a lifting component, and a vibration supply component. The utility model utilizes the lifting component and the water filter plate. When agricultural products are put into the soaking tank, the water filter plate can effectively receive the agricultural products, preventing them from sinking directly to the bottom. After the soaking treatment of the agricultural products is completed, the lifting component can control the water filter plate to move to the open part of the soaking tank, allowing operators to conveniently pick up the agricultural products at the open part of the soaking tank.

[0004] However, in this solution, agricultural products are pretreated only by soaking, which may result in incomplete pretreatment. At the same time, soaking alone cannot completely remove pesticide residues on agricultural products, so there is a problem of inaccurate detection of pesticide residues. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, Example 1, an integrated instrument for agricultural product pretreatment and pesticide residue detection, includes a base 1, which provides a mounting support foundation for the entire device. A soaking barrel 2 is provided on the base 1, and a cantilever assembly 3 is provided on the base 1. A material carrier cage 4 for holding agricultural product materials is rotatably provided on the cantilever assembly 3. The cantilever assembly 3 provides adjustable support for the material carrier cage 4. The cantilever assembly 3 can drive the material carrier cage 4 in and out of the soaking barrel 2, which is convenient for unloading and feeding agricultural products in the material carrier cage. The cantilever assembly 3 is provided with a driver 5 that cooperates with the material carrier cage 4 in transmission. The soaking barrel 2 is connected to an inlet and outlet liquid system 6, and the inlet and outlet liquid system 6 is respectively connected to a clean water tank 7 and an inspection box 8, thereby connecting the soaking barrel and the clean water tank, and then supplying water to the soaking barrel through the clean water tank. The inspection box 8 is provided with a pesticide residue detector 9.

[0024] During use, this embodiment first loads the agricultural products to be pretreated into a material carrier cage. The cantilever assembly is then controlled to lift the cage above the soaking barrel. Clean water from the clean water tank is then passed into the soaking barrel via the inlet and outlet systems. The cage, containing the agricultural products, is then lowered into the soaking barrel for soaking. During the soaking process, the actuator can be activated continuously or intermittently, causing the cage to rotate within the soaking barrel, causing the water within the barrel to flush the agricultural products within the cage. The actuator's speed can be adjusted to control the flushing force. This rinses pesticide residues from the surface of the agricultural products into the water, simultaneously completing the pretreatment process. The rinsed water is then discharged through the inlet and outlet systems into a testing chamber, where it is then tested using a pesticide residue detector. The soaking barrel is then refilled with water until the pesticide content of the water discharged into the testing chamber meets the standard, indicating that the pretreatment and pesticide residue testing for the caged agricultural products have been completed. This embodiment utilizes a driver to drive the material carrying cage to rotate in the water of the soaking barrel, thereby reducing pesticide residues on the surface of agricultural products and performing more thorough pretreatment and cleaning of agricultural products. During the cleaning process, pesticide residues on the surface of agricultural products are dissolved in water and discharged into the inspection box, resulting in a higher degree of integration and more efficient pretreatment and detection processes.

[0025] Example 2, based on Example 1, Figure 2 As shown, the cantilever assembly 3 includes a hydraulic lift column 31 rotatably mounted on a base 1. Specifically, in this embodiment, the base is provided with a rotating platform, with the lower end of the hydraulic lift column mounted on the rotating platform. This allows the hydraulic lift column to rotate relative to the base, thereby changing its orientation. A cantilever 32 is fixedly mounted on the top of the hydraulic lift column 31, and a material carrier 4 is rotatably mounted on the outer end of the cantilever 32. In this embodiment, to facilitate the loading and unloading of agricultural products within the material carrier cage and pretreatment, the hydraulic lift column is used to lift the material carrier cage out of the soaking barrel before pretreatment begins. The cage is then manually rotated and lowered to the ground to one side. The agricultural products are then loaded into the cage. After loading is complete, the hydraulic lift column 31 is controlled to move the material carrier upward. The hydraulic lift column is then rotated to align the material carrier cage with the soaking barrel, and the cage is then placed into the water in the soaking barrel.

[0026] As a further embodiment, the boom 32 includes a connecting base 321 fixed to the top of the hydraulic lifting column 31. This base 321 is connected to a telescopic rod section 322, which is slidably connected to a telescopic rod section 323. A mounting base 324 is provided at the front end of the telescopic rod section 323, and the material carrier 4 is rotatably mounted on this mounting base 324. Specifically, in this embodiment, to facilitate the extension and retraction of the telescopic rod section relative to the telescopic rod section, a hydraulic telescopic cylinder 325 is provided between the telescopic rod section 322 and the telescopic rod section 323. By controlling the extension and retraction of the hydraulic telescopic rod 325, the boom length, and therefore the horizontal position of the material carrier, can be controlled. Furthermore, in this embodiment, the driver 5 is secured to the mounting base 324 via a bracket.

[0027] Example 3, based on Example 2, the material carrying cage 4 includes a cage-like frame 41, with a rotating shaft 42 fixedly connected to the axis of the cage-like frame 41. The rotating shaft 42 rotates in conjunction with the cantilever 32. At the same time, a bearing is provided between the rotating shaft and the cantilever mounting seat to ensure rotation. At the same time, a shaft shoulder is provided on the rotating shaft to cooperate with the mounting seat to prevent axial movement and improve axial bearing capacity. The driver 5 is in transmission connection with the rotating shaft 42. In this embodiment, the rotating shaft and the cage-like frame provide the structural foundation for the entire material carrying cage. The output end of the driver 5 is in transmission conjunction with the rotating shaft 42 via a belt drive pair 51. When it is necessary to drive the material carrying cage to rotate, the driver operates and synchronously drives the rotating shaft to rotate through the belt drive pair, thereby driving the entire material carrying cage to rotate.

[0028] In addition, in order to limit the position of agricultural products in the material carrying cage, a cover net is provided outside the cage-shaped frame 41, and a cage door for taking in and putting in materials is opened on the cover net.

[0029] The soaking barrel 2 includes a barrel body 21 with an opening at the top. The outermost diameter of the material carrier cage is smaller than the diameter of the top opening to facilitate entry and exit. The barrel body 21 is provided with a fixed bracket 22, which is fixedly connected to the base 1, thereby fixing and supporting the barrel body of the soaking barrel. In addition, correspondingly, a circular baffle 45 is provided on the top of the cage-like frame 41. The circular baffle 45 is used to cooperate with the top opening of the barrel body 21. When the material carrier cage is lowered into the soaking barrel, the circular baffle is lowered until it can correspond to the top opening of the barrel body, thereby achieving the closure of the top opening as much as possible. When the material carrier cage rotates, the stirred water is minimized from flying out of the top opening.

[0030] Example 4, based on Example 3, Figure 3As shown, the liquid inlet and outlet system 6 includes an inlet pipe 61 connected to the soaking tub 2 and the clean water tank 7, respectively. A liquid pump 62 is provided on the inlet pipe 61. The soaking tub 2 is connected to the inspection tank 8 via an outlet pipe 63. Furthermore, solenoid valves are provided on both the inlet pipe 61 and the outlet pipe 63. When water needs to be supplied to the soaking tub, the solenoid valve on the inlet pipe is opened, simultaneously activating the liquid pump, which then pumps clean water from the clean water tank into the soaking tub.

[0031] In this embodiment, the soaking bucket is higher than the inspection box as a whole, so that after a single flush, the solenoid valve of the liquid outlet pipe is opened, and the water in the soaking bucket can automatically enter the inspection box under the action of gravity.

[0032] As a further optional real-time method, both the inspection box 8 and the soaking barrel 2 are connected to a drain pipe. In the scenario where agricultural products need to be rinsed multiple times for pretreatment, the water after the first few rinses can be directly discharged to the outside through the drain pipe.

[0033] In this embodiment, the detection end of the pesticide residue detector 9 is connected to the inspection box 8. The pesticide residue detector can optionally adopt a conventional existing model of pesticide residue detector. The pesticide residue detector can be directly fixed on the base or fixed on the top of the inspection box. The detection end of the pesticide residue detector is inserted into the inspection box, which can timely test the pesticide content in the water inside the inspection box.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
