A water valve is installed on the side wall of the detection box. The water valve is connected to the bottom of the filter cup through a water guide pipe. This application reduces the steps of transferring nematodes, making the operation simple, efficient, and practical. However, when inspecting pine wood, the device requires a long waiting time to soak the pine wood in liquid, which reduces the practicality of the device.

[0004] Based on this, a combined filter-washing separator for pine wood nematodes is now provided, which can eliminate the drawbacks of existing devices. UTILITY MODEL CONTENTS

[0017] This invention utilizes the coordination between a motor, a cam, a housing, connecting arm one, connecting arm two, and a spring. Starting the motor drives the rotating shaft, which in turn rotates the cam. When the highest point of the cam's outer wall protrusion gradually contacts the outer wall of connecting arm one, connecting arm one moves the housing to the left. The housing then moves connecting arm two and the connecting plate synchronously, causing the spring to extend. As the cam's protrusion gradually moves away from the outer wall of connecting arm one, the spring's elastic force causes the connecting plate and connecting arm two to move the housing to the right. The housing then moves the separation filter cartridge synchronously, creating a reciprocating left-right oscillation. This increases the liquid flow rate within the separation filter cartridge, accelerating the leaching of pine wood nematodes and thus speeding up the separation of pine wood nematodes, improving separation efficiency, and saving separation time.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5As shown, a combined washing and filtering separator for pine wood nematodes includes an installation frame 1. A base 11 is fixedly connected to the bottom of the installation frame 1. A slide rail 12 is fixedly connected to the bottom of the inner cavity of the installation frame 1. A drive mechanism 2 is fixedly connected to the top right side of the installation frame 1. A swing mechanism 3 is slidably connected to the top of the installation frame 1. The swing mechanism 3 includes a housing 31 and a connecting arm 32. The left side of the connecting arm 32 is fixedly connected to the top right side of the housing 31. A connecting arm 33 is fixedly connected to the top left side of the housing 31. The outer wall of the connecting arm 33 is slidably connected to the top of the installation frame 1. Drain pipes 36 are fixedly connected to the bottom of the front and rear sides of the housing 31. A pine wood nematode separation mechanism 4 is fixedly connected to the top of the housing 31. The drive mechanism 2 drives the connecting arm 32, the housing 31, and the connecting arm 33 in the swing mechanism 3 to reciprocate, thereby accelerating the liquid flow rate in the pine wood nematode separation mechanism 4, thus accelerating the separation of pine wood nematodes, improving separation efficiency, and saving separation time.

[0026] In an optional embodiment, such as Figures 1-3 As shown, the drive mechanism 2 includes a support plate 21. A motor 22 is fixedly connected to the top of the support plate 21. A rotating shaft 23 is fixedly connected to the output end of the motor 22. A fixed plate 24 is rotatably connected to the rear of the rotating shaft 23. The left side of the fixed plate 24 is fixedly connected to the top of the right side of the mounting frame 1. A cam 25 is fixedly connected to the outer wall of the rotating shaft 23. The outer wall of the cam 25 overlaps with the right side of the connecting arm 32. By starting the motor 22, the rotating shaft 23 is driven to rotate, which in turn drives the cam 25 to rotate, causing the outer wall of the cam 25 to contact the outer wall of the connecting arm 32. When the highest point of the protrusion on the outer wall of the cam 25 gradually contacts the outer wall of the connecting arm 32, the connecting arm 32 continuously slides to the left on the inner wall of the mounting frame 1, causing the housing 31 to move synchronously.

[0027] In an optional embodiment, such as Figures 1-4 As shown, the inner walls of connecting arm 1 32 and connecting arm 2 33 are slidably connected to limit blocks 13. The outer wall of the limit block 13 is fixedly connected to the top of the mounting frame 1. The limit blocks 13 limit the movement of connecting arm 1 32 and connecting arm 2 33 to prevent them from moving too far.

[0028] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the limiting block 13 is T-shaped. The limiting block 13 clamps the connecting arm 1 32 and the connecting arm 2 33, so that the connecting arm 1 32 and the connecting arm 2 33 will not wobble when moving left and right.

[0029] In an optional embodiment, such as Figure 2As shown, a connecting plate 34 is fixedly connected to the left side of the connecting arm 33, and springs 35 are evenly distributed on the right side of the connecting plate 34. The right side of the springs 35 is fixedly connected to the top of the left side of the mounting frame 1. Through the springs 35 on the outer wall of the connecting plate 34, when the connecting arm 33 moves to the left to the maximum distance, the elastic force of the springs 35 drives the connecting plate 34 and the connecting arm 33 to move to the right, thereby driving the box 31 to move synchronously, achieving the effect of the box 31 swinging back and forth.

[0030] In an optional embodiment, such as Figure 2 As shown, four sliders 311 are evenly distributed on the bottom of the box 31. The bottom of the sliders 311 is slidably connected to the top of the slide rail 12. Through the cooperation between the slide rail 12 and the sliders 311, the box 31 is more stable during left and right sliding.

[0031] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the pine wood nematode separation mechanism 4 includes a separation filter cylinder 41. A sealing cap 42 is threadedly connected to the top of the separation filter cylinder 41, and a water outlet pipe 43 is fixedly connected to the bottom of the separation filter cylinder 41. Valves are provided on the inner wall of the water outlet pipe 43. The bottom of the water outlet pipe 43 passes through the outer wall of the mounting frame 1 and communicates with the inner wall of the drain pipe 36. A magnetic ring 46 is fixedly connected to the bottom of the inner cavity of the separation filter cylinder 41. A filter screen layer 44 is magnetically attracted to the top of the magnetic ring 46. The outer wall of the filter screen layer 44 is slidably connected to the inner cavity of the separation filter cylinder 41. A pull rod 45 is fixedly connected to the top of the filter screen layer 44. After the separation work is completed, the valve in the water outlet pipe 43 is opened, and the liquid in the separation filter cylinder 41 is discharged into the drain pipe 36 through the water outlet pipe 43. Then the liquid is discharged through the drain pipe 36. Then the sealing cap 42 is opened, and the pull rod 45 is pulled to remove the filter screen layer 44 from the magnetic ring 46. Then the nematodes left on the filter screen layer 44 can be collected and tested.

[0032] In an optional embodiment, such as Figure 5 As shown, the filter layer 44 is composed of multiple filters, and the mesh number of the filters increases from top to bottom. Through the multi-layer distribution of the filter layer 44, the larvae and adults of nematodes can be distinguished.

[0033] The above embodiment discloses a combined washing and filtering separator for pine wood nematode. When pine wood samples need to be quarantined, the samples are cut into uniformly sized pieces, wrapped in gauze, and placed into the separation filter cartridge 41. Liquid is then added to the separation filter cartridge 41. After the liquid is added, the sealing cap 42 is placed on the separation filter cartridge 41 to seal it. The motor 22 is then started, driving the rotating shaft 23 to rotate. The rotating shaft 23 then drives the cam 25 to rotate, causing the outer wall of the cam 25 to contact the outer wall of the connecting arm 32. When the highest point of the protrusion on the outer wall of cam 25 gradually contacts the outer wall of connecting arm 32, connecting arm 32 slides to the left on the inner wall of mounting frame 1, causing housing 31 to move synchronously. Housing 31 then drives connecting arm 33 and connecting plate 34 to move synchronously, thereby extending spring 35. At the same time, housing 31 drives slider 311 to slide on the outer wall of slide rail 12, with slider 311 supporting and guiding housing 31, making the sliding of housing 31 more stable. Meanwhile, limiting block 13 slides on the inner walls of connecting arm 32 and connecting arm 33 respectively, with limiting block 13 supporting the sliding of connecting arm 32. Block 13 limits the movement of connecting arms 32 and 33 to prevent excessive movement. As the protrusion of cam 25 gradually moves away from the outer wall of connecting arm 32, the connecting plate 34 and connecting arm 33, under the elastic force of spring 35, drive the housing 31 to move to the right, thus creating a reciprocating left-right swing, accelerating the liquid flow rate. The increased liquid flow rate accelerates the leaching of pine wood nematodes, thereby speeding up the separation of pine wood nematodes, improving separation efficiency, and saving separation time. After the separation is completed, the valve in the outlet pipe 43 is opened to allow the separation filter cartridge to be opened. The liquid inside 41 is discharged into the drain pipe 36 through the water outlet pipe 43, and then discharged through the drain pipe 36. Then, the sealing cover 42 is opened, the pull rod 45 is pulled, and the filter layer 44 is removed from the magnetic ring 46. Then, the nematodes left on the filter layer 44 can be collected and tested. In summary, by placing the pine wood that needs to be quarantined into the pine wood nematode separation mechanism 4, and then driving the swing mechanism 3 to swing back and forth by the drive mechanism 2, the liquid flow speed in the pine wood nematode separation mechanism 4 is accelerated, thereby accelerating the separation of pine wood nematodes and improving the separation efficiency.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
