[0029] In a specific case of the present embodiment, the protective box includes two protective shells 1, a handle 2 and a pull rod 3. The two protective shells 1 are symmetrically arranged on both sides of a guide frame 6. A guide groove 8 is symmetrically formed on the guide frame 6. A matching block 5 that slides with the guide groove 8 is arranged in the protective shell 1. The handle 2 is movably arranged between the two protective shells 1. The handle 2 is movably connected to the protective shell 1 through the pull rod 3. A group of universal wheels 4 are symmetrically and movably arranged on each of the protective shells 1.

[0036] It should be noted that the position conversion of the storage tank 15 in this embodiment is not limited to being driven by the above-mentioned incomplete bevel gear 19 and transmission wheel 20, but can also be directly driven by a stepper motor or a servo motor. In order to improve the automation level and economic benefits of the entire device and reduce electricity costs, this application adopts the matching method of the incomplete bevel gear 19 and the transmission wheel 20.

[0037] When the solid sample enters the sample input cylinder 10, causing the resistance block 12 to move along the through window 11, the push arm 13 controls the conversion drive module to work. When the conversion drive module works, the rotating sleeve 31 is controlled to rotate relative to the three-way pipe 17, and the rotation angle is 180 degrees, thereby driving the position of the mounting plates 32 on both sides of the rotating sleeve 31 to switch. In this process, the storage tanks 15 on the upper and lower sides of the rotating sleeve 31 are connected to the three-way pipe 17 respectively. By setting the cooperation between the valve pipe 29 and the material guide seat 28, during the rotation of the rotating sleeve 31, the material guide can be driven The seat 28 rotates relative to the valve tube 29 to ensure that the feed port 33 on one side is connected to the tee 17, and in the process of the sleeve and the mounting plate 32 rotating relative to the tee 17, the driven plate and the incomplete bevel gear 19 meet and mesh, so that they can rotate to a set angle, thereby driving the sample mounting seat 34 to rotate to a set angle, switching the storage tanks 15 at different positions to be connected to the feed port 33 on the mounting plate 32 in turn, thereby controlling the storage tanks 15 at different positions to receive different samples respectively, thereby realizing the separate storage of natural product extraction samples.

[0038] See also Figure 1-Figure 8 As another preferred embodiment of the present application, the conversion drive module includes a driving wheel 22, a driven wheel 21 and a transmission structure. The driven wheel 21 is movably mounted on the three-way pipe 17 and connected to the material guide seat 28. The driving wheel 22 is movably arranged on the mounting frame 7 and meshes with the driven wheel 21. The transmission structure is arranged on the mounting frame 7 and is movably connected to the push arm 13. When the push arm 13 moves, it controls the transmission structure to work and drives the driving wheel 22 to rotate.

[0039] In this exemplary embodiment, the transmission structure includes a fixed plate 16, a drive shaft 23, a clamping tube 25 and a rotating member. The fixed plate 16 is set on the mounting frame 7, the drive shaft 23 is movably set on the fixed plate 16 and is movably connected through the push arm 13 and the resistance block 12, the clamping tube 25 is movably set on the fixed plate 16 and one end is slidably clamped in the driving wheel 22, the end of the drive shaft 23 away from the push arm 13 is slidably inserted in the clamping tube 25, the rotating member is set between the clamping tube 25 and the drive shaft 23, and the rotation of the clamping tube 25 is controlled by the rotating member when the drive shaft 23 moves linearly relative to the clamping tube 25.

[0040] It should be supplemented that the rotating member includes a ball 24 and a spiral groove 26 . The ball 24 is at least one and is slidably embedded on the outer wall of the driving shaft 23 . The spiral groove 26 is arranged on the inner wall of the clamping tube 25 and slidably cooperates with the ball 24 .

[0041] When a solid sample is inputted so that the abutment block 12 moves relative to the through window 11, the push arm 13 can be used to drive the drive shaft 23 to move in the clamping tube 25. Under the sliding cooperation between the ball 24 and the spiral groove 26, the clamping tube 25 and the driving wheel 22 can be driven to rotate. Then, under the meshing action between the driving wheel 22 and the driven wheel 21, the driven wheel 21 is driven to rotate, and the rotation angle is 180°, so as to achieve the following example. Figure 5 The positions of the storage tanks 15 on the upper and lower sides are shown to be switched.

[0042] How this application works:

[0043] The whole device can be moved to the working position by the staff carrying the handle 2. By releasing the handle 2 and pressing the handle 2, the sliding cooperation between the matching block 5 and the guide groove 8 can drive the protective shell 1 to move away from each other, and the protective box is unfolded. When the liquid sample is input into the sample input tube 10, the liquid sample has a high flow freedom, and the existence of the resistance block 12 will not affect the liquid sample.

In this process, the storage tanks 15 on the upper and lower sides of the rotating sleeve 31 are respectively connected to the three-way pipe 17. By setting the cooperation between the valve pipe 29 and the material guide seat 28, during the rotation of the rotating sleeve 31, the material guide seat 28 can be driven to rotate relative to the valve pipe 29, so that the feed port 33 on one side can be ensured to be connected with the three-way pipe 17, and in the process of the sleeve and the mounting disk 32 rotating relative to the three-way pipe 17, the driven disk and the incomplete bevel gear 19 meet and mesh, so that they can rotate the set angle, thereby driving the sample mounting seat 34 to rotate the set angle, switching the storage tanks 15 at different positions to be connected with the feed port 33 on the mounting disk 32 in turn, thereby controlling the storage tanks 15 at different positions to receive different samples respectively, thereby realizing the separate storage of natural extract samples. After each sample input is completed, the water tank 9 is controlled to work and the solenoid valve 18 is controlled to be closed. At this time, the solenoid valve 18 isolates the three-way pipe 17 from the storage tank 15. The water input into the three-way pipe 17 by the water tank 9 can be discharged from the sample input tube 10, and the sample input tube 10 and the three-way pipe 17 can be rinsed and cleaned.
