[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 6As shown, an embodiment of the present invention provides a pesticide residue detection sample preparation device, comprising a processing box 1; two hydraulic rods 2 are fixedly connected to the top of the inner side wall of the processing box 1; a fixing block 4 is fixedly connected to the output end of the two hydraulic rods 2; a limiting box 5 is fixedly connected to the bottom of the fixing block 4; multiple movable blade holders 6 are slidably connected inside the limiting box 5, and the multiple movable blade holders 6 are arranged in a linear array; each of the multiple movable blade holders 6 is slidably connected to a sliding rod 8, and the end of the sliding rod 8 is fixedly connected to the side wall of the adjacent movable blade holder 6; a composite... A positioning spring 9 is provided, and a return spring 9 is sleeved on the slide rod 8; a limit bolt 10 is threadedly connected to the side wall of the movable tool holder 6, and the limit bolt 10 is located on the side wall on the same side as the slide rod 8; a tool 7 is fixedly connected to the bottom of the movable tool holder 6; during operation, the operator can place the test sample to be sliced ​​inside the processing box 1, and by driving two hydraulic rods 2, the height of multiple tools 7 is lowered, ultimately achieving the slicing of the sample. If it is necessary to reduce the slice thickness of the sample, the operator can apply pressure to the end of the movable tool holder 6. When pressure is applied to the movable blade holder 6 at the end, the pressure is evenly distributed across the return springs 9 between the multiple movable blade holders 6 due to the corresponding arrangement of sliding rods 8 and return springs 9. Since the multiple return springs 9 are of the same size, their deformations are approximately equal, resulting in a proportional reduction in the distance between the multiple movable blade holders 6. At this point, the operator can drive the hydraulic rod 2 to complete the slicing. The fixing block 4 connects the hydraulic rod 2 and the limiting box 5. The operator can control the minimum distance between the multiple movable blade holders 6 by adjusting the length of the limit bolt 10 protruding from the movable blade holder 6. Through the above structure, the slicing assembly consisting of the limiting box 5, movable blade holders 6, blades 7, sliding rods 8, and return springs 9 achieves adjustable slicing width, solving the problem of low flexibility in traditional agricultural product testing slicing devices, enhancing the applicability and practicality of the device, expanding its application range, and reducing equipment costs.

[0027] like Figure 4As shown, a motor 19 is fixedly connected to the side wall of the fixed block 4; a threaded rod 21 is fixedly connected to the output end of the motor 19, and the threaded rod 21 is rotatably connected inside the fixed block 4; a moving block 20 is threadedly connected to the side wall of the threaded rod 21; a third limiting rod 22 is slidably connected inside the moving block 20, the two third limiting rods 22 are correspondingly arranged, and the two ends of the two third limiting rods 22 are fixedly connected to the inner side wall of the fixed block 4; a clamping frame 23 is fixedly connected to the side wall of the moving block 20; a pressing rod 25 is fixedly connected to the side wall of the clamping frame 23; during operation, the operator can drive the motor 19 to make the pressing rod 25 press against the movable blade holder 6 located at the end, thereby realizing the automatic adjustment of the slicing thickness of the device. During the process, whenever the motor 19 fixed to the side wall of the fixed block 4 is driven, the output of the motor 19 is... The threaded rod 21 at the end will rotate. At this time, since the moving block 20 is threadedly connected to the threaded rod 21 and the moving block 20 is limited by the fixed block 4 and the two third limit rods 22, the moving block 20 will move horizontally. Along with the movement of the moving block 20, the clamping frame 23 fixed to the side wall of the moving block 20 and the extrusion rod 25 fixed to the side wall of the clamping frame 23 will move. The operator can continuously drive the motor 19 until the extrusion rod 25 extrudes the multiple movable blade holders 6 to the predetermined spacing. Through the above structure, by setting the extrusion assembly composed of the motor 19, moving block 20, threaded rod 21, third limit rod 22, clamping frame 23 and extrusion rod 25, the spacing of the slicing assembly is automatically adjusted, which improves the automation level of the device and enhances its practicality and convenience.

[0028] like Figure 3 As shown, a limiting block 12 is fixedly connected to the side wall of the limiting box 5, and the limiting block 12 is set to correspond to the size of the processing box 1; a second limiting rod 14 is slidably connected inside the limiting block 12, and the two second limiting rods 14 are arranged correspondingly; the two ends of the two second limiting rods 14 are fixedly connected to the inner side wall of the processing box 1; a first limiting rod 3 is provided between the processing box 1 and the fixing block 4; a movable baffle 13 is fixedly connected to the bottom of the limiting block 12; during operation, whenever the slicing assembly moves vertically inside the processing box 1, the limiting block fixed to the side wall of the limiting box 5... The 12 will move together with it. Since the limiting block 12 is slidably connected to the two second limiting rods 14, the first limiting rod 3, the limiting block 12 and the second limiting rod 14 can together restrict the movement posture of the slicing assembly to prevent it from tilting. The movable baffle 13 prevents the sample tissue fluid from splashing. Through the above structure, by setting the first limiting rod 3, the limiting block 12 and the second limiting rod 14 to restrict the movement posture of the slicing assembly, the operation of the device is more stable, the stability of the device is enhanced, and the maintenance requirements of the device are reduced.

[0029] like Figure 6As shown, a mounting plate 18 is fixed to the inner wall of the processing box 1; a liquid holding tank 15 is provided inside the processing box 1, and the size of the liquid holding tank 15 corresponds to that of the processing box 1; a support net 16 is fixed to the inner wall of the liquid holding tank 15; during operation, the operator can place the sample to be tested on the top of the support net 16, and as the slicing component slices, the liquid overflowing from the sample will enter the interior of the liquid holding tank 15 through the support net 16, wherein the mounting plate 18 serves to position the liquid holding tank 15; through the above structure, by setting the liquid holding tank 15 and the support net 16 to hold the sample tissue fluid, leakage of tissue fluid is avoided, and the mounting plate 18 is set to position the liquid holding tank 15, which enhances the practicality and convenience of the device.

[0030] like Figure 1 and Figure 6 As shown, a fixed glass plate 26 is fixedly attached to the side wall of the processing box 1; a slot is provided on the side wall of the processing box 1; a movable glass plate 27 is provided at the top of the slot, and the movable glass plate 27 is set to correspond to the size of the slot; during operation, the operator can place the sample inside the processing box 1 and then place the movable glass plate 27 into the slot. As the slicing assembly operates, the tissue fluid splashed from the sample will be blocked by the fixed glass plate 26 and the movable glass plate 27; through the above structure, by setting the fixed glass plate 26 and the movable glass plate 27 to block the splashing of sample tissue fluid, the airtightness of the device is improved, which is conducive to maintaining the cleanliness of the operator's working environment and reducing the difficulty of cleaning the device and the workbench.

[0031] like Figure 6 As shown, a flow guide plate 17 is fixedly attached to the inner wall of the liquid collection tank 15, and the flow guide plate 17 is set according to the size of the liquid collection tank 15. During operation, the flow guide plate 17 fixed to the inner wall of the liquid collection tank 15 is inclined, and the sample tissue fluid entering the liquid collection tank 15 will flow to the end of the liquid collection tank 15 under its own gravity. Through the above structure, by setting the flow guide plate 17 to guide the sample tissue fluid to the end of the liquid collection tank 15, it provides convenience for the staff to tilt and clean the device components, which helps to improve the work efficiency of the staff.

[0032] like Figure 4 As shown, the bottom of the clamping frame 23 is provided with clamping plates 24, and the two clamping plates 24 are set in positions and dimensions corresponding to the liquid tank 15 and the support net 16. During operation, the two clamping plates 24 can pass through the gap between the liquid tank 15 and the support net 16. With the movement of the moving block 20, the two clamping plates 24 will squeeze the sample placed on top of the support net 16, thereby pushing the sample to the bottom of the slicing assembly. Through the above structure, by setting the clamping plates 24 to position the sample, the sample is positioned at the bottom of the slicing assembly, avoiding sample displacement and enhancing the practicality of the device.

[0033] During operation, the operator places the test sample to be sliced ​​inside the processing box 1 and lowers the height of multiple blades 7 by driving two hydraulic rods 2, ultimately slicing the sample. To reduce the slice thickness, pressure is applied to the movable blade holder 6 at the end. Because sliding rods 8 and return springs 9 are arranged correspondingly between the multiple movable blade holders 6, the pressure on the end movable blade holder 6 is evenly distributed across the return springs 9. Since the multiple return springs 9 are of the same size, their deformations are approximately equal. Therefore, the multiple movable blade holders... The spacing between the blade holders 6 will decrease proportionally. At this point, the operator can drive the hydraulic rod 2 to complete the slicing. The fixing block 4 connects the hydraulic rod 2 and the limiting box 5. The operator can control the minimum spacing between multiple movable blade holders 6 by adjusting the length of the limit bolt 10 exposed to the movable blade holder 6. The operator can drive the motor 19 to cause the extrusion rod 25 to extrude and compress the movable blade holder 6 located at the end, thereby realizing the automatic adjustment of the slicing thickness of the device. During the process, whenever the motor 19 fixed to the side wall of the fixing block 4 is driven, the threaded rod 21 located at the output end of the motor 19 will rotate. At this time, since the moving block 20 is threadedly connected to the threaded rod 21, and the moving block 20 is subjected to the fixed rod 21, the moving block 20 will rotate. With the fixed block 4 and the two third limiting rods 22 limiting the movement of the moving block 20, the moving block 20 will move horizontally. Along with the movement of the moving block 20, the clamping frame 23 fixed to the side wall of the moving block 20 and the extrusion rod 25 fixed to the side wall of the clamping frame 23 will move. The operator can continuously drive the motor 19 until the extrusion rod 25 extrudes the multiple movable blade holders 6 to a predetermined distance. Whenever the slicing assembly moves vertically inside the processing box 1, the limiting block 12 fixed to the side wall of the limiting box 5 will move along with it. Since the limiting block 12 is slidably connected to the two second limiting rods 14, the first limiting rod 3, the limiting block 12, and the second limiting rod 14 can together restrict the movement posture of the slicing assembly, preventing it from tilting. The sample is tilted, with the movable baffle 13 preventing splashing of the sample tissue fluid. The operator can place the sample to be tested on top of the support mesh 16. As the slicing assembly slices, any liquid overflowing from the sample will flow through the support mesh 16 into the liquid collection tank 15. The clamping platform 18 positions the liquid collection tank 15. After placing the sample inside the processing chamber 1, the operator can place the movable glass plate 27 into the clamping slot. As the slicing assembly operates, any splashing tissue fluid will be blocked by the fixed glass plate 26 and the movable glass plate 27. The drainage plate 17, fixed to the inner wall of the liquid collection tank 15, is tilted, allowing the sample tissue fluid entering the liquid collection tank 15 to flow towards the end of the tank under its own gravity.Two clamping plates 24 can pass through the gap between the liquid tank 15 and the support mesh 16. With the movement of the moving block 20, the two clamping plates 24 will compress the sample placed on top of the support mesh 16, thereby pushing the sample towards the bottom of the slicing assembly.
