Description

Technical Field

[0001] This utility model relates to the field of pesticide residue detection and extraction technology, specifically to a pesticide residue detection and extraction device. Background Technology

[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, corn, wheat, and sweet potatoes. Agricultural products and fruits and vegetables are the main foods from which the human body ingests vitamins. Studies have shown that people who regularly eat agricultural products and fruits and vegetables are healthier than those who do not. Furthermore, the vitamins contained in agricultural products and fruits and vegetables can have skin-whitening effects and prevent diseases. Therefore, agricultural products and fruits and vegetables have become the best choice in people's daily lives.

[0003] A Chinese patent with announcement number CN215843379U discloses a pesticide residue extraction device for agricultural products, including a housing, a screw and a slider spirally connected, a protective frame fixedly connected to the bottom end of a fixed plate, a third motor fixedly connected to the bottom end of the fixed plate, a stirring roller fixedly connected to the top end of the main shaft of the third motor, and a support column fixedly connected to the bottom end of a circular plate. This technical solution improves the performance of the squeezing roller by using an extrusion plate, improves the crushing effect by using a first and second cutting blade arranged in a cross pattern, and controls the crushing time of agricultural products by controlling the movement of the sealing plate driven by the second motor. Since the support column is located at the bottom corner of the circular plate and forms an off-axis with the main shaft of the third motor, and the spring causes the support plate to squeeze the filter plate, the filter plate vibrates, preventing debris from clogging the filter plate. This device has broad market value and is worth promoting.

[0004] When testing agricultural products for pesticide content, an extractor is used to break the agricultural products into a liquid state. At this time, the broken agricultural products will release some harmful gases, which will be discharged from the feed port of the extractor. If workers inhale the harmful gases for a long time, it will affect their health. Utility Model Content

[0005] This invention provides a pesticide residue detection and extraction device that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a pesticide residue detection and extraction device, comprising:

[0008] Extractor;

[0009] A hydraulic press, mounted on the surface of the extractor, is used to help crush agricultural products placed inside the extractor.

[0010] The extrusion roller, installed inside the extractor, is used to extrude and crush agricultural products;

[0011] The delivery pipe, installed on the side wall of the extractor, is used to extract the liquid agricultural product produced after crushing;

[0012] A detoxification device is installed on the surface of the extractor to adsorb and collect the gas emitted from the feed port of the extractor.

[0013] A cleaning device, installed on the surface of the extractor, is used to clean agricultural products from the lower surface of the hydraulic press.

[0014] Furthermore, the detoxification device includes a base plate, which is fixedly connected to the surface of the extractor. A telescopic plate is slidably connected to the surface of the base plate, and a mounting frame is fixedly connected to the surface of the telescopic plate. A motor is installed on the inner wall of the mounting frame, and a connecting frame is fixedly connected to the surface of the telescopic plate. An internal frame is rotatably connected to the inner wall of the connecting frame. The output end of the motor is fixedly connected to the internal frame, and an arc plate is slidably connected to the surface of the connecting frame.

[0015] With the above technical solution, when agricultural products are placed inside the extractor, they are turned into powder liquid by the action of hydraulic press and extrusion roller. At the same time, the liquid will release toxic gases contained in pesticides. Operators can place activated carbon plates on the inner wall of the built-in frame, so that the toxic gases released to the outside will be adsorbed on the surface of the activated carbon plates and will not be released to the outside to affect the health of the workers.

[0016] Furthermore, a guide plate is fixedly connected to the surface of the connecting frame.

[0017] Through the above technical solution, the guide plate can guide the toxic gas outside the opening towards the connecting frame, thereby improving the absorption effect of toxic gas.

[0018] Furthermore, a first gear is fixedly connected to the output end of the motor, an extension plate is fixedly connected to the surface of the base plate, a second gear is rotatably connected to the surface of the extension plate, the teeth of the second gear and the teeth of the first gear are both meshed with an internal toothed belt, a rotating rod is fixedly connected to the surface of the second gear, and four air guide plates are fixedly connected to the surface of the rotating rod.

[0019] The above technical solution drives the first gear to rotate when the motor is working, which in turn drives the second gear to rotate in conjunction with the internal gear belt, which in turn drives the air guide plate to rotate. This allows a large amount of toxic gas emitted to the outside to be guided into the interior of the connecting frame, thus improving the detoxification effect.

[0020] Furthermore, an outer plate is fixedly connected to the surface of the telescopic plate, and a round rod is fixedly connected to the surface of the extractor. The outer plate is slidably connected to the round rod, and a rotating plate is rotatably connected to the surface of the round rod. The rotating plate is L-shaped.

[0021] With the above technical solution, pulling the telescopic plate upwards can cause the entire detoxification device to slide upwards, and then rotating the rotating plate can lock onto the lower surface of the outer plate, thereby limiting the entire detoxification device and making it convenient for operators to place agricultural products into the extractor.

[0022] Furthermore, the cleaning device includes an external frame, which is fixedly connected to the surface of the extractor. A rotating frame is rotatably connected to the surface of the external frame, and a cleaning rod is slidably connected to the inner wall of the rotating frame. Several bristles are fixedly connected to the surface of the cleaning rod.

[0023] The above technical solution allows the cleaning rod to enter the extractor by rotating the rotating frame, thereby bringing the bristles on the cleaning rod into contact with the hydraulic device. The bristles remove agricultural products adhering to the surface of the hydraulic rod, preventing the agricultural products from sticking to the surface of the hydraulic device and affecting the subsequent testing results of other agricultural products.

[0024] Furthermore, an auxiliary plate is fixedly connected to the inner wall of the rotating frame. The auxiliary plate is annular and is slidably connected to the cleaning rod.

[0025] With the above technical solution, the auxiliary plate is compatible with the cleaning rod. When cleaning the hydraulic device, the cleaning rod can be placed inside the auxiliary plate, which in turn helps the cleaning rod to slide and rotate easily, improving the convenience of cleaning.

[0026] Furthermore, the inner wall of the rotating frame is provided with a circular hole, and one end of the cleaning rod is fixedly connected to a limit block, which is conical.

[0027] The above technical solution uses a limiting block to limit the cleaning rod, preventing it from falling out of the rotating frame when placed. Instead, it moves to the circular hole, making it easier for staff to pick it up during use.

[0028] The above-described solution of this utility model has at least the following beneficial effects:

[0029] 1. This utility model, by setting up a detoxification device, can adsorb and recover the toxic gases emitted from the extracted liquid when extracting pesticides from agricultural products inside the extractor, so that the gases will not be inhaled by the surrounding staff, thereby improving the health of the staff and further increasing the practicality of the extraction device.

[0030] 2. This utility model, by setting up a cleaning device, can clean the agricultural products adhering to the surface of the hydraulic press after the hydraulic press performs auxiliary squeezing on the agricultural products, so that the agricultural products to be tested will not adhere to the surface of the hydraulic press, and thus the test results will not be different when testing other agricultural products in the future.

[0038] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0039] like Figures 1 to 5 As shown, an embodiment of this utility model provides a pesticide residue detection and extraction device, comprising:

[0040] Extractor 1; Hydraulic unit 2, installed on the surface of extractor 1, used to help crush agricultural products placed inside extractor 1; Extrusion roller 3, installed inside extractor 1, used to crush agricultural products; Conveying pipe 4, installed on the side wall of extractor 1, used to remove the liquid agricultural products generated after crushing; Detoxification device 5, set on the surface of extractor 1, used to adsorb and collect the gas emitted from the feed port of extractor 1; Cleaning device 6, set on the surface of extractor 1, used to clean the agricultural products on the lower surface of hydraulic unit 2.

[0041] like Figures 1 to 4As shown, the detoxification device 5 includes a base plate 501, which is fixedly connected to the surface of the extractor 1. A telescopic plate 509 is slidably connected to the surface of the base plate 501, and a mounting frame 503 is fixedly connected to the surface of the telescopic plate 509. A motor 504 is mounted on the inner wall of the mounting frame 503. A connecting frame 502 is fixedly connected to the surface of the telescopic plate 509, and an inner frame 510 is rotatably connected to the inner wall of the connecting frame 502. The output end of the motor 504 is fixedly connected to the inner frame 510. An arc plate 511 is slidably connected to the surface of the connecting frame 502. When agricultural products are placed inside the extractor 1, they will be detoxified. The hydraulic unit 2 and the extrusion roller 3 work together to turn the liquid into a powder. Simultaneously, the liquid releases toxic gases contained in the pesticide. Operators can place activated carbon plates on the inner wall of the built-in frame 510, thus adsorbing the toxic gases released to the outside onto the surface of the activated carbon plates, preventing them from affecting the health of the workers. A guide plate 512 is fixedly connected to the surface of the connecting frame 502. The guide plate 512 guides the toxic gases outside the opening towards the connecting frame 502, improving the absorption effect of the toxic gases. The output end of the motor 504 is fixedly connected to the first gear 505, and the base plate 5... An extension plate 507 is fixedly connected to the surface of 01. A second gear 508 is rotatably connected to the surface of the extension plate 507. The teeth of the second gear 508 mesh with the teeth of the first gear 505 through an internal toothed belt 506. A rotating rod 516 is fixedly connected to the surface of the second gear 508. Four air guide plates 517 are fixedly connected to the surface of the rotating rod 516. When the motor 504 is working, it drives the first gear 505 to rotate, which in turn drives the second gear 508 to rotate in conjunction with the internal toothed belt 506. This further drives the air guide plates 517 to rotate, thus directing a large amount of toxic gas emitted to the outside towards the connecting frame 5. The internal guidance of 02 improves the detoxification effect. The surface of the telescopic plate 509 is fixedly connected to the outer plate 513, and the surface of the extractor 1 is fixedly connected to the round rod 514. The outer plate 513 and the round rod 514 are slidably connected. The surface of the round rod 514 is rotatably connected to the rotating plate 515. The rotating plate 515 is "L" shaped. Pulling the telescopic plate 509 upward can drive the detoxification device 5 to slide upward. Then, rotating the rotating plate 515 can be locked onto the lower surface of the outer plate 513, thereby limiting the overall position of the detoxification device 5. This makes it convenient for operators to place agricultural products into the interior of the extractor 1.

[0042] In this embodiment of the invention (working principle), when agricultural products are placed, the telescopic plate 509 is pulled upwards. The telescopic plate 509 drives the detoxification device 5 to slide. After moving to the appropriate position, the rotating plate 515 can be rotated to the position of the lower surface of the outer plate 513, thereby achieving a limiting effect. At this time, the operator can place the agricultural products inside the extractor 1. Through the cooperation of the hydraulic device 2 and the squeezing roller 3 and the internal parts, the liquid is extracted. When the hydraulic device 2 and the squeezing roller 3 are activated, the outer plate 513 can be disengaged from the limiting position and placed on the surface of the bottom plate 501. Then, the arc plate 511 is slid open, allowing the activated carbon plate to be placed on the inner wall of the built-in frame 510. The arc plate 511 is then slid closed, and the motor 504 is started. The motor 504 drives the built-in frame 510 to rotate, allowing the toxic gas guided by the inner guide plate 512 to be adsorbed and detoxified by the activated carbon plate. At the same time, when the motor 504 is working, it can drive the first gear 505 to rotate, which in turn drives the second gear 508 and the rotating rod 516 to rotate through the inner toothed belt 506. The rotation of the rotating rod 516 can drive the air guide plate 517 to guide the gas into the interior of the connecting frame 502, thereby achieving the detoxification effect.

[0043] like Figure 1 and Figure 2 as well as Figure 5 As shown, the cleaning device 6 includes an outer frame 61, which is fixedly connected to the surface of the extractor 1. A rotating frame 62 is rotatably connected to the surface of the outer frame 61, and a cleaning rod 64 is slidably connected to the inner wall of the rotating frame 62. Several bristles 66 are fixedly connected to the surface of the cleaning rod 64. By rotating the rotating frame 62, the cleaning rod 64 can enter the extractor 1, thereby allowing the bristles 66 on the cleaning rod 64 to contact the hydraulic unit 2. The bristles 66 can remove agricultural products adhering to the surface of the hydraulic rod, preventing agricultural products from adhering to the surface of the hydraulic unit 2 and affecting the subsequent testing results of other agricultural products. An auxiliary plate 65 is fixedly connected to the inner wall of the rotating frame 62. The auxiliary plate 65 is circular and is slidably connected to the cleaning rod 64. The auxiliary plate 65 and the cleaning rod 64 are adapted to each other. When cleaning the hydraulic device 2, the cleaning rod 64 can be placed inside the auxiliary plate 65. The auxiliary plate 65 can help the cleaning rod 64 to slide and rotate easily, improving the convenience of cleaning. The inner wall of the rotating frame 62 is provided with a circular hole 63. One end of the cleaning rod 64 is fixedly connected to a limiting block 67. The limiting block 67 is conical. The limiting block 67 can limit the cleaning rod 64 so that it will not fall out of the rotating frame 62 when placed. It needs to be moved to the position of the circular hole 63, which is convenient for the staff to pick up when using it.

[0044] In this embodiment of the invention, after the agricultural product is extracted, rotating the rotating frame 62 allows the cleaning rod 64 to be in a horizontal state. Then, the cleaning rod 64 is slid so that it is on the inner wall of the auxiliary plate 65. The cleaning rod 64 is then slid towards the hydraulic unit 2. After sliding to the bottom of the hydraulic unit 2, the cleaning rod 64 can be pulled and rotated back and forth. With the help of the brush bristles 66 on the surface, the agricultural product attached to the output end of the hydraulic unit 2 can be cleaned off. After the brush bristles 66 have been used for a long time, the cleaning rod 64 can be removed from the circular hole 63 for replacement.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
