Description

Technical Field

[0001] The utility model relates to the technical field of pesticide finished product detection, in particular to pesticide finished product detection sampling equipment used in pesticide production. Background Art

[0002] Pesticides refer to chemical agents used in agriculture to prevent and control pests and diseases and regulate plant growth. They are widely used in agricultural, forestry, and animal husbandry production, environmental and household hygiene pest control and epidemic prevention, and industrial product mildew and moth prevention. Pesticides can be used to kill insects, fungi, and other organisms that harm crop growth. Existing pesticides require sampling and testing of finished products during production to determine whether the proportion of each drug meets the standards, so as to avoid exceeding the drug standards and polluting the ecological environment.

[0003] Patent publication CN221404891U discloses a finished pesticide product testing and sampling device for pesticide production, belonging to the field of pesticide production technology. The device comprises a processing box, which also includes multiple storage cylinders. The multiple storage cylinders are symmetrically distributed and fixed to the inner sidewall of the processing box. Multiple symmetrically distributed cover plates are rotatably connected to one side of the processing box sidewall. A sampling assembly compatible with the storage cylinders is provided on the top sidewall of the processing box. The utility model can extract and sample different types of finished pesticides for testing through the arrangement of the sampling component, and is applicable to sampling different types of finished pesticides. It has strong applicability and should be used for testing of a wide variety of pesticides. In addition, it has a good anti-volatilization effect in the sampling and testing of pesticides, and has a certain degree of preservation effect on pesticides. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. The arrangement of the sampling component solves the problem of difficulty in sampling and testing a variety of finished pesticides, which affects the efficiency of sampling work. In actual use, When testing finished pesticides, solid particles inside them will settle to the bottom of the pesticide barrel while the finished pesticides are still. When sampling the finished pesticides inside the barrel for testing, a sampling tube needs to be placed at the bottom of the barrel. However, due to the toxicity of pesticides and the dark color of the barrel itself, which can block the impact of sunlight on the finished pesticides, it is very easy for the sampling tube to be placed inside the finished pesticide barrel. The sampling position of the sampling tube cannot be observed from the outside of the barrel. As a result, the sampling tube cannot sample the finished pesticide samples at the bottom of the barrel, affecting the accuracy of subsequent testing results of the finished pesticides. To this end, a new technical solution is needed to solve this problem. Utility Model Content

[0026] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0027] Example 1: A pesticide finished product testing and sampling device for pesticide production, see Figures 1 to 4 , the side of the sampling tube 11 is fixedly connected to the drain pipe 15, and the side of the drain pipe 15 is fixedly installed with a control valve 16, which is characterized in that a mounting frame 13 is vertically fixedly installed at the middle end of the top of the fixed plate 1, and an electric push rod 14 is vertically fixedly installed inside the mounting frame 13. The bottom of the electric push rod 14 drive shaft is fixedly installed with the sampling tube 11 through a coupling, and the sampling tube 11 is located below the fixed plate 1, and a transmission plate 22 is movably provided on the outside of the bottom of the sampling tube 11. A blocking mechanism is provided inside the sampling tube 11, and the blocking mechanism is connected to the top of the transmission plate 22 for transmission, and the inside of the sampling tube 11 A pushing mechanism is provided on the top, and the pushing mechanism and the blocking mechanism are transmission-connected. Control mechanisms are provided on both sides of the sampling tube 11. Through the cooperation of the blocking mechanism and the pushing mechanism, the sampling tube 11 is moved to the bottom of the barrel body. The pesticide at the bottom of the inner side of the barrel can then flow into the sampling tube 11 through the liquid inlet groove 24 for storage. At the same time, when the sampling tube 11 is removed from the bottom of the barrel body, the pesticide product sample will leak arbitrarily and affect the accuracy of the subsequent sample test results. At the same time, it is convenient for the operator to sample and test the pesticide product at the bottom of the barrel.

[0028] For details, see Figures 1 to 4 The sealing mechanism includes a connecting rod 21 and a sealing gasket. A liquid inlet groove 24 is opened at the bottom of the sampling tube 11, and the number of the liquid inlet grooves 24 is several groups. A connecting rod 21 is vertically fixedly installed on the top surface of the transmission plate 22. A sealing gasket is fixedly sleeved on the outer side of the connecting rod 21, and the sealing gasket is sealed and fits the inner wall of the liquid inlet groove 24. Through the transmission action of the connecting rod 21 on the sealing gasket, after the sampling tube 11 moves to the bottom of the holding barrel, the sealing gasket can be automatically removed from the liquid inlet groove 24 to ensure that the pesticide sample can flow from the liquid inlet groove 24 to the inside of the holding barrel for sampling and collection.

[0029] For further information, see Figures 1 to 4 The pushing mechanism includes a pushing spring 28, a hollow frame 26 is fixedly installed on the top inner side of the sampling tube 11, and an extrusion plate 27 is slidably installed on the bottom inner side of each hollow frame 26. A pushing spring 28 is movably sleeved inside each sampling tube 11, and the bottom of the pushing spring 28 is movably fitted to the top surface of the extrusion plate 27. A pushing rod 25 is vertically fixedly installed at the bottom of each extrusion plate 27, and the pushing rod 25 is slidably inserted into the bottom end of the hollow frame 26. Under the reverse pushing action of the pushing spring 28, after the sampling tube 11 is removed from the bottom of the barrel, the transmission plate 22 can automatically restore its position and drive the sealing gasket to seal the liquid inlet tank 24 to prevent leakage.

[0030] It is worth noting that, see Figures 1 to 4 A movable plate 2 is slidably installed at the bottom inner side of the sampling tube 11, and the top of the connecting rod 21 is fixedly connected to the bottom of the movable plate 2, and the bottom of the movable plate 2 is fixedly connected to the top of the pushing rod 25. The connecting rod 21 and the pushing rod 25 are transmission-connected through the movable plate 2, so that after the transmission plate 22 is vertically lifted by the resistance, the pushing rod 25 can drive the extrusion plate 27 to extrude the return spring.

[0031] It is worth noting that see Figures 1 to 4 The control mechanism includes a pressure sensor 3 and a controller 32. The pressure sensor 3 is fixedly installed on the middle end of the top inside the sampling tube 11, and a movable rod 31 is vertically fixedly installed on the middle end of the top of the movable plate 2, and the movable rod 31 and the pressure sensor 3 are in the same vertical position. The controller 32 is fixedly installed on the middle end surface of the side of the fixed plate 1. The signal output end of the pressure sensor 3 is electrically connected to the signal input end of the controller 32, and the signal output end of the controller 32 is electrically connected to the signal input end of the electric push rod 14. The pressure information generated by the contact between the movable rod 31 and it is detected by the pressure sensor 3, and then the controller 32 controls the operation of the electric push rod 14 to improve the automatic movement of the entire sampling tube 11.

[0032] It is worth mentioning that see Figures 1 to 4, support frames 12 are slidably sleeved on both sides of the outside of the fixed plate 1, and a tightening bolt 41 is vertically screwed on the top of each support frame 12 through a thread. Limiting slide grooves 4 are provided on both sides of the top of the fixed plate 1, and the bottom of the tightening bolt 41 is movably inserted into the limiting slide groove 4. By sliding the support frame 12 on the outside of the fixed plate 1, the horizontal position of the support frame 12 on the outer wall of the fixed plate 1 can be adjusted according to the inner diameter of the barrel itself, thereby realizing the adaptability adjustment of the overall support length.

[0033] It is worth mentioning that see Figures 1 to 4 A fixing frame 5 is fixedly installed on the bottom surface of each support frame 12, and an adjusting bolt 51 is screwed laterally on the side of each fixing frame 5 through a thread. A fitting arc plate 52 is rotatably installed on the side of each adjusting bolt 51 through a bearing, and the fitting arc plate 52 is movably arranged on the inner side of the fixing frame 5. An anti-slip friction pad 53 is fixedly bonded to the outer surface of each fitting arc plate 52. The tightening position of the fitting arc plate 52 can be adjusted by twisting the adjusting bolt 51, thereby improving the installation stability of the overall sampling mechanism.

[0034] During operation, when it is necessary to sample and test the finished pesticide product placed inside the storage barrel, the tightening bolt 41 is screwed to disengage it from the inner bottom wall of the limiting slide 4, and the support frame 12 is pulled outward to move and adjust it on the outside of the fixing plate 1, so that the overall length of the support frame 12 and the fixing plate 1 can be adapted to the diameter of the top surface of the storage barrel, so that the fixing frame 5 can be clamped on the top outer wall of the storage barrel, and then the adjusting bolt 51 is screwed to drive the fitting arc plate 52 to move horizontally on the outer wall of the storage barrel synchronously, until the side of the fitting arc plate 52 can fit the outer wall of the storage barrel, and then the overall support frame 12 and the fixing plate 1 are installed and fixed. The controller 32 then starts the pressure sensor 3 and the electric push rod 14, so that the electric push rod 14 provides a corresponding driving force to the sampling tube 11 during operation, so that the sampling tube 11 can penetrate into the interior of the storage barrel until the sampling tube 11 moves to the bottom of the storage barrel, and contacts the transmission plate 22 below the sampling tube 11 on the inner bottom wall of the storage barrel. As the sampling tube 11 continues to descend, the inner bottom wall of the storage barrel causes a resistance to the bottom surface of the transmission plate 22, causing it to rise synchronously. Under the transmission action of the connecting rod 21, the sealing gasket can be driven to rise vertically inside the liquid inlet tank 24 synchronously until it moves out of the liquid inlet tank 24, so that the liquid inlet tank 24 can be in an open state. , so that the finished pesticide at the bottom of the inner side of the storage barrel can flow through the liquid inlet tank 24 to the inside of the sampling tube 11 for storage and collection, driving the abutting rod 31 to contact the pressure sensor 3, so that the pressure sensor 3 can detect the contact pressure information generated by the abutting rod 31 on it, and then combined with the conversion analysis of the pressure information by the controller 32, after the pressure information reaches the set threshold, the controller 32 is operated to control the electric push rod 14 to operate and drive the sampling tube 11 to automatically lift and move from the inside of the finished pesticide storage barrel. In the process of the sampling tube 11 descending for sampling, the transmission plate 22 is vertically lifted, and at the same time, it can drive the push rod 25 to move synchronously inside the hollow frame 26. It is lifted vertically, so that the extrusion plate 27 causes the push spring 28 inside the hollow frame 26 to resist and deform it. When the sampling tube 11 is lifted and removed after sampling, the push spring 28 pushes the movable plate 2 and the connecting rod 21 below it to quickly restore their positions, thereby driving the sealing gasket to descend and seal the liquid inlet trough 24, thereby preventing the finished pesticide product inside the sampling tube 11 from leaking and affecting subsequent testing and use. After the sampling tube 11 is lifted and removed from the storage barrel, the control valve 16 is opened to discharge the pesticide sample inside the sampling tube 11 through the drain pipe 15, and then the finished pesticide product is tested.
