Description

Technical Field

[0001] The present invention relates to the technical field of agricultural products, and in particular to a device for detecting pesticide residues in agricultural products. Background Art

[0002] Agricultural products, as the direct product of agricultural activities, are an indispensable and important resource for maintaining human life, supporting economic development and promoting social progress. They are deeply rooted in vast fields, dense forests, vast grasslands and abundant waters. Through the hard work and wise management of farmers, they are transformed into a wide range of food and industrial raw materials to meet people's growing and diversified needs. From the perspective of types, agricultural products cover an extremely wide range. In the field of planting, food crops such as wheat, rice, corn, etc., constitute the basis of human staple food; cash crops such as cotton, oil crops (soybeans, rapeseed, etc.), and sugar crops (sugarcane, sugar beets, etc.) provide indispensable raw materials for industries such as textiles, edible oils, and sugar. Forestry products, such as wood, bamboo, forest fruits, etc., are not only building materials, but also important consumer goods in people's lives. Animal husbandry provides a wealth of meat (pork, beef, mutton, etc.), eggs, milk and other products, which are an important source of protein intake. Fishery products, including various fish, shrimps, crabs, shellfish and other aquatic products, are deeply loved by consumers for their unique delicious taste and rich nutritional value. The production of agricultural products is a complex and delicate process, which is jointly affected by multiple factors such as natural conditions, technical level, market demand, and policy environment. In agricultural production, farmers need to scientifically and rationally arrange planting or breeding plans according to different crop growth cycles, soil conditions, climatic conditions and other factors, and adopt advanced agricultural technologies and equipment to improve the yield and quality of agricultural products. At the same time, the production of agricultural products is also guided by market demand. Farmers need to adjust the production structure and variety layout according to changes in market demand to meet the diverse needs of consumers. The circulation and sales of agricultural products are also crucial. In order to ensure the smooth circulation of agricultural products, governments at all levels and relevant departments need to build a complete agricultural product market system, including wholesale markets, retail markets, e-commerce platforms, etc., to facilitate the transaction of agricultural products. At the same time, strengthen the construction of agricultural product logistics infrastructure, improve the transportation and storage capacity of agricultural products, and reduce the loss of agricultural products during the circulation process. In addition, through brand building, marketing planning and other means, enhance the popularity and competitiveness of agricultural products, broaden sales channels, and allow more high-quality agricultural products to enter a broader market.

[0003] As the valuable result of agricultural production, agricultural products are not only related to human survival and development, but also affect economic prosperity and social progress. We should attach great importance to the production, circulation and sales of agricultural products, strengthen agricultural science and technology innovation and talent training, improve the output and quality of agricultural products, and contribute to building a more prosperous and sustainable agricultural industry system.

[0004] When conducting pesticide residue detection on agricultural products, it is necessary to ensure the efficiency of pesticide residue detection and make the detection more timely during the detection process. However, we consider that the traditional pesticide residue detection method is too single and the operator needs to directly contact the test object, which will affect the accuracy of pesticide residue detection and is extremely inconvenient. Therefore, an agricultural product pesticide residue detection equipment is urgently needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a pesticide residue detection device for agricultural products, which solves the problem that the pesticide residue detection method in the prior art is too single and the operator needs to directly contact the detection object, which will affect the accuracy of pesticide residue detection.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A pesticide residue detection device for agricultural products, comprising a frame, a bidirectional screw is rotatably connected to one side of the inner side of the frame, and a driving motor is fixedly connected to one side of the top of the frame by bolts, and the top of the bidirectional screw passes through the top of the frame and is drivingly connected to the output shaft of the driving motor, both ends of the bidirectional screw are screwed with nut seats by threaded engagement, and one side of one of the two nut seats is fixedly connected to a top plate, and one side of the other nut seat is fixedly connected to a bottom plate, the bottom of the top plate is fixedly connected to a pressure plate, and the top of the bottom plate is fixedly connected to a bearing frame, and the inner side of the bearing frame is fixedly connected to a plurality of bearing cylinders, wherein the bottom of the pressure plate is fixedly connected to a plurality of pressure rods used in conjunction with the bearing cylinders;

[0008] A support plate is fixedly connected to one side of the top plate, and a support rod is slidably connected to the bottom of the support plate, and the bottom end of the support rod is fixedly connected to a collecting plate, the bottom of the collecting plate is rotatably connected to a rotating rod, and the top end of the rotating rod passes through the collecting plate, and a cleaning brush is fixedly connected to the top end of the rotating rod.

[0009] Preferably, the bottom end of the bidirectional screw is rotatably connected to the inner bottom of the frame through a rotating shaft, and the top end of the bidirectional screw passes through the top of the frame through a bearing sleeve.

[0010] Preferably, both sides of the top plate and both sides of the bottom plate are fixedly connected with sliders, and all the sliders are slidably connected to the inner wall of the frame through sliding grooves.

[0011] Preferably, one side of the two nut seats is fixedly connected with a protrusion, and the two protrusions are slidably connected to the side wall of the frame through the movable groove.

[0012] Preferably, a sliding block is fixedly connected to the top end of the support rod, and the sliding block is slidably connected to the support plate through a sliding groove.

[0013] Preferably, the top end of the rotating rod passes through the collecting plate via a bearing sleeve, and all the pressure rods are distributed in a one-to-one correspondence with all the bearing cylinders.

[0014] The present invention has at least the following beneficial effects:

[0015] When the agricultural product pesticide residue detection device of the present invention is used, the agricultural products to be detected are first placed one by one in all the carrying tubes, and the driving motor is started to drive the bidirectional screw to rotate, so that the two nut seats can be driven to move away from or close to each other, and the top plate and the bottom plate are driven to move relative to each other through the two nut seats, so that all the pressure rods are respectively inserted into all the carrying tubes to squeeze the agricultural products to be detected, so that part of the detection body of the agricultural products adheres to the pressure rods, and then the driving motor is started to drive the bidirectional screw to rotate, so that the top plate and the bottom plate can be separated, and the pressure rod and the carrying tube are separated at the same time, and then the support rod is slid manually to move the collecting plate to The bottom of the pressing plate is then manually rotated to drive the cleaning brush to rotate, which in turn can drive the cleaning brush to clean all the pressing rods, so that the agricultural products to be tested that are adhered to the pressing rods fall off onto the collecting plate, and finally the collecting plate is pulled out to test the objects. Compared with the existing pesticide residue detection method that is too single and the operator needs to directly contact the test object, which will affect the accuracy of pesticide residue detection, the method proposed in the present invention squeezes the agricultural products in the carrying cylinder through the pressing rod, and then cleans the agricultural products adhered to the pressing rod to the collecting plate through the cleaning brush for subsequent testing, which is very convenient.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] Embodiment 1

[0025] Reference Figure 1-5 , including a frame 1, a bidirectional screw rod 2 is rotatably connected to one side of the inner side of the frame 1, and a driving motor 12 is fixedly connected to one side of the top of the frame 1 by bolts, and the top end of the bidirectional screw rod 2 passes through the top of the frame 1 and is drivingly connected to the output shaft of the driving motor 12, both ends of the bidirectional screw rod 2 are screwed with nut seats 3 by threaded engagement, and one side of one of the two nut seats 3 is fixedly connected to a top plate 4, and one side of the other nut seat 3 is fixedly connected to a bottom plate 7, a pressing plate 5 is fixedly connected to the bottom of the top plate 4, and a bearing frame 8 is fixedly connected to the top of the bottom plate 7, and a plurality of bearing tubes 9 are fixedly connected to the inner side of the bearing frame 8, wherein a plurality of pressing rods 6 used in conjunction with the bearing tubes 9 are fixedly connected to the bottom of the pressing plate 5;

[0026] A support plate 13 is fixedly connected to one side of the top plate 4, and a support rod 14 is slidably connected to the bottom of the support plate 13, and a collecting plate 15 is fixedly connected to the bottom end of the support rod 14, and a rotating rod 16 is rotatably connected to the bottom of the collecting plate 15, and the top end of the rotating rod 16 passes through the collecting plate 15, and a cleaning brush 17 is fixedly connected to the top end of the rotating rod 16.

[0027] First, the operator needs to place the agricultural product samples to be tested one by one and in order in the multiple bearing tubes 9 built into the equipment. These bearing tubes 9 are exquisitely designed to support the agricultural products stably and ensure that the integrity of the agricultural products is not damaged during the subsequent extrusion process. Then, by starting the built-in drive motor 12 of the equipment, the motor will serve as a power source to drive the bidirectional screw 2 to start rotating. The unique design of the bidirectional screw 2 enables it to simultaneously drive the two nut seats 3 to move relative or opposite to each other along the axial direction of the bidirectional screw 2 during rotation. This mechanism is cleverly converted into the mutual approach or distance between the top plate 4 and the bottom plate 7, thereby driving all the pressure rods 6 connected thereto to be accurately inserted into the agricultural products in each bearing tube 9. The key to this step is that through moderate extrusion, a small amount of test bodies on the surface or inside of the agricultural products are caused to adhere to the pressure rod 6, providing samples for subsequent detection and analysis. After completing the sample collection, the drive motor 12 is started again to make the bidirectional screw 2 rotate in the opposite direction, thereby causing the top plate 4 to separate from the bottom plate 7, driving the pressure rod 6 to be slowly withdrawn from the bearing tube 9, and ensuring that the agricultural product samples remain in their original state and are not damaged. Next, in order to efficiently collect the test bodies on the pressure rod 6, the operator needs to manually slide the support rod 14. This action will guide the collection plate 15 to move smoothly to the bottom of the pressure plate 5, ensuring that all test bodies that fall off the pressure rod 6 can be accurately captured. This design not only simplifies the sample collection process, but also greatly improves the sample recovery rate. Furthermore, by manually rotating the rotating rod 16, the cleaning brush 17 can be driven to start working. The cleaning brush 17 is made of special materials, which can effectively remove the residues on the pressure rod 6 without causing damage to the surface of the pressure rod 6. As the rotating rod 16 rotates, the cleaning brush 17 sweeps across each pressure rod 6 in an all-round and dead-angle manner, ensuring that all adhered test bodies are thoroughly cleaned and fall onto the collection plate 15 below. Finally, the operator only needs to simply pull the collection plate 15 out of the device to send the collected test body samples to the laboratory for further pesticide residue analysis. The whole process is not only easy and quick to operate, but also significantly improves the accuracy and efficiency of detection through precise mechanical control and efficient sample collection mechanism, providing strong technical support for agricultural product safety.
