[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6 The tobacco root sampling device shown includes a cutting blade 1, and further includes:

[0026] The outer casing 2 is disposed outside the cutting blade 1 and is used to store the cutting blade 1.

[0027] Pushing component 3 is disposed on the top of housing 2. Pushing component 3 is used to move cutting blade 1. Pushing component 3 includes pushing block 31. The bottom end of pushing block 31 is provided with mounting plate 33 for mounting cutting blade 1. A connecting member for linkage between pushing block 31 and mounting plate 33 is provided between pushing block 31 and mounting plate 33.

[0028] The blocking bristles 4 are located inside the housing 2 and are used to block soil particles.

[0029] Specifically, one end of the outer casing 2 has a movable groove, the cutting blade 1 is slidably inserted into the movable groove, one end of the movable groove is connected to the outer wall of one end of the outer casing 2, the inner wall of the movable groove has an exposure groove for exposing part of the cutting blade 1, the exposure groove is located in the middle of the movable groove, one end of the blocking bristles 4 is fixedly connected to the inner wall of the exposure groove, the top of the inner wall of the movable groove has a movable hole, the connecting part includes a linkage rod 32, the linkage rod 32 is inserted into the movable hole, the top and bottom ends of the linkage rod 32 are fixedly connected to the bottom end of the push block 31 and the top end of the mounting plate 33 respectively, the interior of the outer casing 2 has a cavity, the cavity is located directly above the movable groove, the top of the inner wall of the cavity has a through hole, the linkage rod 32 is inserted into the through hole, the outer wall of the linkage rod 32 is fitted with a first limiting plate 34 and a second limiting plate 35, the first limiting plate 34 and the second limiting plate 35 are located at the top and bottom ends of the movable hole respectively.

[0030] Furthermore, the outer shell 2 consists of two symmetrically arranged elongated shells, which are fixedly connected by bolts. The outer shell 2 is made of a magnetically attractive metal material. The length of the moving groove is twice the length of the cutting blade 1, the length of the moving hole corresponds to the length of the cutting blade 1, and the size of the through hole corresponds to the size of the moving hole. One end of the moving groove penetrates the outer wall of the outer shell 2. The pushing block 31 is located at the end of the outer shell 2 away from the moving groove penetrating the outer shell 2. The length of the second limiting plate 35 corresponds to the moving hole, and the width of the second limiting plate 35 is 1.5 times the width of the moving hole. The pushing block 31 is welded and fixed to the top end of the linkage rod 32, and the bottom end of the linkage rod 32 is welded and fixed to the top end of the mounting plate 33. The mounting plate 33 is fixedly connected to the cutting blade 1 by bolts. The first limiting plate 34 is located directly above the second limiting plate 35. The first limiting plate 34 and the second limiting plate 35 are fixedly connected to the linkage rod 32 by welding, respectively. The straight-line distance between the opposite sides of the first limiting plate 34 and the second limiting plate 35 is... Corresponding to the height of the moving hole, the width of the first limiting plate 34 is 1.5 times the width of the moving hole. Thus, the first limiting plate 34 and the second limiting plate 35 form two clamping plates to clamp the plate between the moving groove and the cavity. The friction between the first limiting plate 34 and the second limiting plate 35 and the plate restricts the movement of the cutting blade 1. When the cutting blade 1 needs to move, the pushing block 31 needs to be pushed manually. The pushing block 31 drives the linkage rod 32, which drives the mounting plate 33 to move the cutting blade 1. The blocking bristles 4 are set on the side of the exposed groove away from the through part of the outer shell 2. Two blocking bristles 4 are symmetrically arranged. The blocking bristles 4 are fixedly connected to the inner wall of the moving groove by the bristle planting method. The side of the blocking bristles 4 facing the cutting blade 1 is closely attached to the outer wall of the cutting blade 1 to prevent soil particles attached to the outer wall of the cutting blade 1 after cutting from entering the moving groove where the uncut part of the cutting blade 1 is stored, thus avoiding contamination of the uncut part of the cutting blade 1.

[0031] Specifically, the interior of the exposure groove is provided with a protective component 5 for shielding the cutting blade 1. The protective component 5 includes a protective cover 51. The top of the protective cover 51 has a groove, and a magnetic block 52 is fixedly connected to the inner wall of the groove. The vertical cross section of the protective cover 51 is U-shaped.

[0032] Furthermore, the magnetic block 52 is an existing magnetic block. The magnetic block 52 is placed in the exposure groove to cover the cutting blade 1. The magnetic block 52 and the outer shell 2 are magnetically attracted to each other to fix the outer shell 2 and the protective cover 51 to prevent the cutting blade 1 from scratching the user's hand when the outer shell 2 is being carried.

[0033] Before sampling, the push block 31 is positioned on the side of the through hole away from the end of the outer shell 2. At this time, the cutting blade 1 only partially enters the exposure groove. Then, the protective cover 51 is pulled away from the outer shell 2 to expose the cutting blade 1 for the first sample cutting and sampling. During cutting, the part of the outer shell 2 that is through always faces the ground, and the end of the outer shell 2 that is not through is higher than the end that is through. This ensures that after the cutting blade 1 cuts, the soil particles attached to the outer wall of the cutting part can roll off through the through part of the outer shell 2. After the cutting and sampling is completed, the device moves to the next sampling point for sampling. The push block 31 is then pushed towards the through part of the outer shell 2 to insert a portion of the uncut part of the cutting blade 1 into the exposure groove for sample cutting and collection again. This process is repeated for multiple sample collections. The cut part is enclosed by the outer shell 2 and will not come into contact with the sample, thus reducing interference with sample collection and reducing the amount of tools carried by the sampling personnel, thereby reducing the burden.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
