In this embodiment, the first hydraulic cylinder 5 is specifically described as being hinged to the mounting frame 1 at its lower end and the first connecting rod 61 at its upper end, that is, the first connecting rod 61 bends downwards from its hinge point with the mounting frame 1 to its hinge end with the first hydraulic cylinder 5.

[0023] like Figure 2 As shown, the tilting device includes a second hydraulic cylinder 7 and a third connecting rod 8. One end of the second hydraulic cylinder 7 is hinged to one end of the third connecting rod 8, and the other end is hinged to a slider 4. The other end of the third connecting rod 8 is hinged to a digging shovel 2. The digging shovel 2 includes a connecting frame at its upper end and a downwardly extending blade 21. Both the slider 4 and the third connecting rod 8 are hinged to the connecting frame. The hinge point between the connecting frame and the third connecting rod 8 is located above the hinge point between the connecting frame and the slider 4. When the second hydraulic cylinder 7 is in the retracted state, the blade 21 is in a vertical state. When the second hydraulic cylinder 7 is extended, the third connecting rod 8 pulls the upper end of the connecting frame inward (inward, i.e., towards the harvester; similarly, outward, i.e. away from the harvester), causing the digging shovel 2 to tilt around the hinge point between the connecting frame and the slider 4, thus achieving the outward tilting of the blade 21.

[0024] like Figure 1As shown, the connecting frame includes two opposing upright plates 22. A first hinge shaft 23 and a second hinge shaft 24, arranged parallel to each other from top to bottom, are positioned between the two upright plates 22. A first connecting plate 25, located below the second hinge shaft 24, is also positioned between the two upright plates 22. A third connecting rod 8 is hinged to the first hinge shaft 23, and a slider 4 is hinged to the second hinge shaft 24. The upper end of the blade shovel 21 is fixedly connected to the first connecting plate 25. Furthermore, the first connecting plate 25 is arranged parallel to the second hinge shaft 24, and multiple blade shovels 21 are arranged side-by-side along the length of the first connecting plate 25.

[0025] like Figure 1 As shown, there are two guide rails 3 arranged side by side along the direction of the second hinge axis 24. There are two sliders 4 arranged one-to-one with the guide rails 3 and connected by the second connecting plate (not shown in the figure). Each slider 4 is provided with a support 13 extending away from the guide rail 3. The end of the two supports 13 away from the slider 4 is hinged to the second hinge axis 24. There are two third connecting rods 8 arranged side by side along the direction of the second hinge axis 24. The second oil cylinder 7 is located between the two second hinge axes 24 and is hinged to the two second hinge axes 24. The first connecting rod mechanism 6 is hinged to the second connecting plate.

[0026] like Figure 1 As shown, the front wheel 9 and rear wheel 10 are respectively provided at the front and rear of the mounting frame 1 (the front corresponds to the direction of travel of the harvester, that is, the opposite direction is the rear). The guide rail 3 is located on the right side of the mounting frame 1, that is, the digging shovel 2 is located on the right side of the mounting frame 1. The moving device and the tilting device are both located on the left side of the digging shovel 2. The seat 11 is provided at the rear of the mounting frame 1, and the fertilizer spreader 12 is provided at the rear of the seat 11.

[0027] The first hydraulic cylinder 5 and the second hydraulic cylinder 7 are initially in a retracted state. When using the Chinese herbal medicine excavation and harvesting machine disclosed in this utility model to excavate Chinese herbal medicines, after the harvester is driven to a suitable position and stopped, the first hydraulic cylinder 5 is extended, and the slider 4 drives the excavating shovel 2 to move downward, so that the blade shovel 21 is inserted into the soil; then the second hydraulic cylinder 7 is extended, and the third connecting rod 8 pulls the upper end of the excavating shovel 2 inward, so that the excavating shovel 2 rotates around the hinge point between the excavating shovel 2 and the slider 4, so that the blade shovel 21 rotates outward, and the Chinese herbal medicines can be dug out to the outside of the harvester; finally, the second hydraulic cylinder 7 and the first hydraulic cylinder 5 are retracted, the blade shovel 21 rotates inward to the original vertical state and the excavating shovel 2 moves upward to the original height, thus completing one excavation operation.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
