Description

Technical Field

[0001] The invention relates to the technical field of pesticide detection, and in particular to a pesticide residue sampling and detection machine which is easy to clean and an operation method thereof. Background Art

[0002] With the improvement of living standards, people's requirements for food quality are also gradually increasing. Before eating agricultural products, it is necessary to test the pesticide residues in them to avoid food poisoning due to excessive pesticide residues. In the process of testing pesticide residues in agricultural products, it is necessary to use a testing machine to test the agricultural product samples. However, the existing testing machines still have certain usage defects during use, such as: The invention announcement number CN220969347U discloses a device for detecting pesticide residues in agricultural products. By designing components such as a motor, a crushing knife, a scraper, a square rod, and a spring, the crushing knife is driven to rotate by the motor housing, and vegetables can be crushed by the crushing knife, which is convenient for detecting pesticide residues in vegetables. The motor housing drives the square rod to rotate, and then the square rod drives the scraper to rotate, and the scraper can be used to scrape the inner wall of the box to prevent vegetables from adhering to the box wall. When the scraper is worn, the square rod can be moved under the elastic action of the spring, and then the square rod drives the scraper to move, so that the scraper can always be in contact with the inner wall of the box, thereby improving the cleaning effect. In the above document, the device will filter the crops through the filter screen during operation, and the crushing knife will crush the crops before filtering. In this process, the agricultural product residue will adhere to the inside of the filter screen. After a period of use, the filter screen needs to be disassembled for cleaning. The filter screen is located inside the device. During the disassembly process, other structures need to be disassembled before the filter screen is disassembled, which brings many inconveniences to the cleaning of the filter screen, making the cleaning process of the filter screen too complicated. Another example is the invention announcement number CN117434228A which discloses a pesticide residue detection device for edible agricultural products. The motor drives the rotating shaft to rotate, so that the connecting sleeve and the crushing blades crush and cut the agricultural products. The connecting sleeve and the rotating shaft can be disassembled, which is convenient for cleaning the connecting sleeve and the crushing blades. The larger agricultural product residues are filtered through the sieve plate, and the lifting rod can take out the sieve plate, which is convenient for cleaning the agricultural product residues on the sieve plate, further reducing the difficulty of cleaning the crushing barrel. At the same time, the support sheet can provide support for the sieve plate, which is convenient for the dripping of the separated agricultural product juice. In the above document, the device is supported by the supporting legs at its lower end during operation. The device needs to be placed in a designated position before use, and the supporting legs at the lower end of the device are fixedly connected to the main body, and the lower end surface of the device is smooth and flat.

DETAILED DESCRIPTION

[0017] 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 described embodiments 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.

[0018] Embodiment 1: This embodiment Figure 1-Figure 5 As shown, in order to solve the problem that the existing inspection machine can only rely on manual handling: A machine body 1 and a feed inlet 2 fixedly mounted on the upper end of the machine body 1; A partition plate 3 and a support plate 4 are fixedly installed inside the body 1, and an extrusion plate 5 is slidably installed between the partition plate 3 and the support plate 4, and a connecting rod 6 is fixedly installed on the side of the extrusion plate 5 close to the body 1, and a limiting rod 7 is fixedly installed on the end of the connecting rod 6 away from the extrusion plate 5, and a limiting groove 8 is provided inside the body 1, and both ends of the limiting rod 7 are located inside the limiting groove 8; The lower end of the body 1 is provided with a lifting structure, and the lifting structure can realize the effect of facilitating the movement of the detection machine; A driving motor 27 is provided inside the lifting structure, and the driving motor 27 is fixedly installed inside the lower end of the machine body 1, and an output shaft 28 is fixedly installed at the output end of the driving motor 27, and a rotating rod 29 is rotatably installed at the lower end of the machine body 1; A moving cylinder 30 is sleeved on the outer side of the rotating rod 29 and the output shaft 28, and a lifting plate 31 is fixedly installed on the lower end of the moving cylinder 30. A pulley structure is sleeved on the outer side of the rotating rod 29 and the output shaft 28, and a roller 32 is fixedly installed on the lower end of the lifting plate 31, and a support leg 33 is fixedly installed on the lower end of the body 1.

[0019] When using the easy-to-clean pesticide residue sampling and detection machine, first place the detection machine at the position where work is required. In the process of placing the detection machine at the designated position, it is necessary to roll it on the upper end of the ground through the roller 32. Before that, the driving motor 27 needs to drive the output shaft 28 to rotate, and the rotating rod 29 will be driven to rotate through the pulley structure during the rotation of the output shaft 28. At this time, the moving cylinder 30 can move downward on the outside of the output shaft 28 and the rotating rod 29, and the downward movement of the moving cylinder 30 will drive the roller 32 to move downward and contact the ground through the lifting plate 31. After the support leg 33 is separated from the ground, the roller 32 can be used to drive the detector to move. After the detection machine moves to the required position, the driving motor 27 can drive the output shaft 28 to rotate in the opposite direction, so that the detection machine is stably supported at this position. The lifting and lowering of the roller 32 effectively improves the convenience of carrying the detection machine.

[0020] Embodiment 2: This embodiment is as follows Figure 1-Figure 2 and Figure 6 As shown, in order to solve the problem that the internal structure of the existing detection machine needs to be manually disassembled and cleaned during the cleaning process: A motion structure is provided inside the body 1, and the motion structure can achieve the effect of automatically ejecting the first filter plate 16 from the inside of the body 1; A fixing member 9 and an electric push rod 10 are arranged inside the motion structure. The fixing member 9 is fixedly mounted on a side of the extrusion plate 5 close to the machine body 1. The electric push rod 10 is fixedly mounted inside the machine body 1, and the electric push rod 10 is arranged corresponding to the extrusion plate 5. A fixed block 11 is fixedly installed at one end of the electric push rod 10 away from the body 1, and a contact block 12 is slidably installed inside the fixed block 11, and a support spring 13 is fixedly installed at one end of the contact block 12 close to the fixed block 11, and a connecting rope 14 is fixedly installed on the outer side of the fixed block 11; A moving plate 15 is slidably mounted inside the support plate 4 , a first filter plate 16 is snap-fittedly mounted inside the moving plate 15 , and the moving plate 15 is fixedly connected to the connecting rope 14 .

[0021] When using the easy-to-clean pesticide residue sampling and testing machine, the operator places the agricultural product sample that needs to be tested for pesticide residues on the upper end of the first filter plate 16 through the feed port 2, and then the electric push rod 10 can drive the fixed block 11 to move. During the movement of the fixed block 11, it will enter the interior of the fixing part 9 and push the squeezing plate 5 to move, and the squeezing plate 5 will squeeze the agricultural product and discharge the liquid inside it. During this process, the residue of the agricultural product will adhere to the upper end of the first filter plate 16, and the first filter plate 16 needs to be disassembled and cleaned. After the agricultural product sample is squeezed, the electric push rod 10 will shrink and make the squeezing plates 5 move away from each other. During this process, the limit rod 7 will slide inside the limit groove 8, and after the limit rod 7 completes sliding inside the limit groove 8, the electric push rod 10 will drive the fixed block 11 to move, and during the movement of the fixed block 11, the contact block 12 will be fixed. The fixed piece 9 is squeezed, and the contact block 12 will move toward the inside of the fixed block 11 and squeeze the supporting spring 13. The supporting spring 13 will shrink after being squeezed, and after the contact block 12 moves to the inside of the fixed block 11, the fixed block 11 can be separated from the fixed piece 9. At this time, the electric push rod 10 will continue to drive the fixed block 11 to move, and the moving plate 15 will be pulled to move from the inside of the machine body 1 during the movement of the fixed block 11. During the movement of the moving plate 15, the first filter plate 16 will be driven to move outward from the inside of the machine body 1, so as to facilitate the removal of the first filter plate 16 for cleaning. After the cleaning is completed, the first filter plate 16 can be put back into the inside of the moving plate 15, and the movement of the electric push rod 10 can make the first filter plate 16 move to the initial position, and the first filter plate 16 is automatically moved out of the inside of the machine body 1, which effectively improves the convenience of cleaning the internal structure of the machine body 1.

[0022] Embodiment 3: This embodiment is as follows Figure 1-Figure 2 and Figure 7-Figure 10 As shown, in order to solve the problem that the existing inspection machine can only rely on manual cleaning: A cleaning structure is provided inside the body 1, and the cleaning structure can automatically clean the second filter plate 17; A second filter plate 17 and a guide plate 18 are provided inside the cleaning structure, and the second filter plate 17 and the guide plate 18 are fixedly installed inside the machine body 1, and a receiving bucket 19 is placed at the lower end of the machine body 1, and a moving part 20 is fixedly installed inside the lower end of the machine body 1, and the moving part 20 is located outside the receiving bucket 19, and an electric cylinder 21 is fixedly installed between the moving part 20 and the machine body 1; Two sets of traction ropes 34 are fixedly installed on the outer side of the moving part 20, and a sliding block 22 is fixedly installed on one end of the traction rope 34 away from the moving part 20, and the sliding block 22 is slidably installed inside the body 1, and a ball 23 is nested and installed on the outer side of the sliding block 22, and a traction wire 35 is fixedly installed on one end of the sliding block 22 away from the traction rope 34, and a weight block 36 is fixedly installed on one end of the traction wire 35 away from the sliding block 22, and the weight block 36 is slidably connected to the body 1; A cleaning roller 24 is rotatably installed inside the sliding block 22, and the cleaning roller 24 is located at the upper end of the second filter plate 17, and gears 25 are fixedly installed at both ends of the cleaning roller 24. A rack 26 is fixedly installed inside the body 1, and the rack 26 is meshed with the gear 25.

[0023] During the squeezing of the agricultural products by the squeezing plate 5, the liquid inside the agricultural products will flow to the inside of the guide plate 18 through the first filter plate 16 and the second filter plate 17, and then flow into the inside of the receiving barrel 19 through the guide plate 18. At this time, the receiving barrel 19 can be taken out and the liquid inside can be tested. During this process, the electric cylinder 21 will push the moving part 20 to move and drive the receiving barrel 19 to slide inside the machine body 1, so that the receiving barrel 19 is close to the front end of the machine body 1, so that the operator can take out the receiving barrel 19. During the movement of the moving part 20, the sliding block 22 will be pulled by the traction rope 34 to move, and the moving part 20 will move inside the machine body 1 through the ball 23. At this time, the cleaning roller 24 will follow the sliding block 22 to move. The cleaning roller 24 is moved and cleans the upper end of the second filter plate 17, and the gear 25 drives the cleaning roller 24 to move under the action of the rack 26, thereby completing the cleaning process of the second filter plate 17 and ensuring that the upper end of the second filter plate 17 is clean. In this process, the traction wire 35 pulls the weight block 36 to move upward under the action of the sliding block 22, and the receiving barrel 19 is taken out and put back into the interior of the moving part 20. At this time, the electric cylinder 21 contracts and makes the receiving barrel 19 move to the initial position. In this process, the weight block 36 pulls the sliding block 22 to the initial position through the traction wire 35, so as to facilitate the cleaning of the second filter plate 17 next time. At this point, the cleaning process of the detection machine is completed, which effectively improves the convenience of cleaning the detection machine and increases the overall practicality.
