[0036] The magnetic force of the magnet 54 is greater than the elastic force of the spring 57;

[0037] In the initial state, the four cutting blocks 61 are in contact with each other to form a cylinder, and the cleaning assembly 5 is located in the middle of the inner wall of the cutting block 61;

[0038] The four cleaning plates 55 are in a state of conflict under the action of the spring 57;

[0039] The opposite ends of the four cutting knives 62 are in a diamond shape, the cutting knives 62 are in an inclined shape, and the opposite ends of the four cutting knives 62 are staggered with each other;

[0040] When the support frame 3 contacts the ground, the saw teeth at the bottom of the four cutting blocks 61 will be inserted into the soil, and the cutting blades 62 will contact the soil.

[0041] The soil sampling point is determined, the middle of the fixing frame 2 is kept vertical with the sampling point, the fixing frame 2 is supported by the support frame 3 in contact with the ground, the bottom of the cutting block 61 is in contact with the ground, and the transmission assembly 7 and the cutting block 61 are driven by the driving motor to rotate. Since the four cutting blocks 61 initially form a cylinder, the weeds on the ground and the top layer of soil are cut in a circular manner by the saw teeth at the bottom of the cutting block 61. At the same time, the cutting knife 62 is in contact with the soil, and the cutting block 61 rotates to drive the cutting knife 62 to cut the weeds in the sampling area.

[0042] After the cutting is completed, the four cutting blocks 61 are pulled by rotating the pushing component 4 to make the second slider 64 slide toward the outer end along the second guide groove 65, thereby expanding the distance between the four cutting blocks 61. During the movement of the four cutting blocks 61 toward the outer end, the second guide frame 51 is driven to move synchronously. Since two adjacent magnets 54 are in contact with each other, the distance between the four first sliders 56 is kept fixed under the action of the magnetic force of the magnets 54. At this time, the first slider 56 will move down along the second guide frame 51, and the four cleaning plates 55 are always in a state of resistance under the action of the spring 57. At this time, the outer wall of the cutting block 61 is in contact with the limiting ring at the other end of the connecting rod 52. When the cleaning plate 55 moves down and contacts the ground (such as Fig.10 ), at this time, the cleaning plate 55 will be located at the opposite end of the cutting knife 62, and the cutting component 6 and the cleaning component 5 will be driven to rotate by the driving motor. The cleaning plate 55 rotates to push the cut weeds and soil to the outside to avoid the presence of weeds or branches and other impurities in the sampling area. After the soil sampling area is cleaned, the cutting block 61 continues to move outward. Since the cutting block 61 contacts the limiting ring at the other end of the connecting rod 52, the cleaning component 5 is driven to move outward synchronously, so that the four cleaning plates 55 are out of conflict, and the sampling device 1 can be used to perform deep sampling of the ecologically restored soil, effectively preventing weeds from entering the sampling device 1 and affecting the effect of soil sampling.

[0043] like Figures 3 to 5 As shown, the transmission assembly 7 includes a transmission ring 71, a docking ring 74 is fixedly mounted on the bottom of the fixing frame 2, a docking groove 73 for the docking ring 74 to engage is provided on the top of the transmission ring 71, an annular groove 72 is provided on the top of the transmission ring 71, and a gear is provided on the inner wall of the annular groove 72;

[0044] A transmission gear 75 is provided on the fixing frame 2 . The transmission gear 75 is located in the annular groove 72 and meshes with the gear. The transmission gear 75 is assembled at the output end of the driving motor.

[0045] The driving motor drives the transmission gear 75 and the transmission ring 71 to rotate, and the cutting block 61 is connected to the transmission ring 71 through the second slider 64, thereby driving the cutting block 61 to rotate to cut the weeds and soil.

[0046] like Figures 3 to 8As shown, the pushing assembly 4 includes a top limiting frame 41 fixed to the fixing frame 2, the inside of the limiting frame 41 is elastically connected to the first guide frame 42 through a spring sheet 48, the inner wall of the limiting frame 41 is provided with a spring latch 43, and the side of the first guide frame 42 is provided with a hole 44 for the spring latch 43 to engage;

[0047] A first guide groove 49 is formed on the inner wall of the limiting frame 41 . A guide block 46 is fixedly mounted on the side of the first guide frame 42 and slides vertically in the first guide groove 49 . A rack 45 is engaged at the top of the first guide frame 42 . A push rod 47 is fixedly mounted on the side of the rack 45 .

[0048] In the initial state, the rack 45 is in a non-meshing state with the transmission gear 75 under the action of the spring 48;

[0049] The rack 45 and the first guide frame 42 move downward, the first guide frame 42 moves vertically downward, the spring latch 43 is engaged in the hole 44, and the rack 45 is meshed with the transmission gear 75;

[0050] The pushing assembly 4 further includes a connecting tube 415 fixedly mounted on the outside of the cutting block 61, the outside of the connecting tube 415 is movably engaged with a butt-joint tube 414, and the outside of the butt-joint tube 414 is fixedly mounted with a pushing frame 411;

[0051] The four connecting pipes 415 are engaged with each other, and the butt-joint pipe 414 is in a "C" shape.

[0052] The driving motor drives the transmission assembly 7 and the cutting assembly 6 to rotate to cut the soil and weeds. During the rotation of the cutting block 61, since the docking tube 414 is in a "C" shape and is engaged with the outside of the connecting tube 415, the connecting tube 415 is driven to rotate and move in the docking tube 414, ensuring that the cutting block 61 can rotate normally.

[0053] like Figure 7 As shown, a connecting frame 413 is fixedly mounted on the top of the pushing frame 411, and a sliding groove 412 for the pushing rod 47 to slide is opened in the middle of the connecting frame 413;

[0054] In the initial state, the rack 45 and the transmission gear 75 are in a non-meshing state, and the push rod 47 is located at the upper end of the slide slot 412 .

[0055] The weeds in the sampling area and the upper soil are cut by rotating the cutting block 61. After the weeds are cut by the cutting block 61, the rack 45 and the first guide frame 42 are pushed downward. The guide block 46 slides downward along the first guide groove 49. The first guide frame 42 compresses the spring sheet 48. The first guide frame 42 is engaged in the hole 44. At this time, the rack 45 is meshed with the transmission gear 75 and the rack 45 is driven to move outward by the transmission gear 75. The rack 45 moves outward along the first guide frame 42. And push the connecting frame 413, the pushing frame 411 and the docking tube 414. Since the docking tube 414 is engaged with the outside of the connecting tube 415, the connecting tube 415 is pulled to move toward the outer end, and the inner diameters of the four connecting tubes 415 are gradually expanded, thereby pulling the four cutting blocks 61 to move toward the outer end, and the cut weeds can be thrown to the outer end through the gap between two adjacent cutting blocks 61 by the cleaning component 5, so as to avoid the presence of weeds in the sampling area, which affects the weeds entering the sampling device 1 during the soil sampling process of the sampling device 1.

[0056] The working principle provided by the present invention is to determine the soil sampling point, keep the middle part of the fixing frame 2 vertical with the sampling point, support the fixing frame 2 by contacting the ground through the support frame 3, and support the bottom of the cutting block 61 by contacting the ground. The transmission assembly 7 and the cutting block 61 are driven by the driving motor to rotate. Since the four cutting blocks 61 initially form a cylinder, the weeds on the ground and the top layer of soil are cut in a circular manner by the saw teeth at the bottom of the cutting block 61. At the same time, the cutting knife 62 is in contact with the soil, and the cutting block 61 rotates to drive the cutting knife 62 to cut the weeds in the sampling area.

[0057] The cutting block 61 is rotated to cut the weeds and the upper soil in the sampling area. After the cutting block 61 has finished cutting the weeds, the rack 45 and the first guide frame 42 are pushed downward. The guide block 46 slides downward along the first guide groove 49. The first guide frame 42 compresses the spring sheet 48. The first guide frame 42 is engaged in the hole 44. At this time, the rack 45 is meshed with the transmission gear 75, and the transmission gear 75 drives the rack 45 to move toward the outer end. The rack 45 moves along the first guide frame 42 to the outer end. The outer end moves and pushes the connecting frame 413, the pushing frame 411 and the docking tube 414. Since the docking tube 414 is engaged with the outside of the connecting tube 415, and the docking tube 414 is "C"-shaped and engaged with the outside of the connecting tube 415, the connecting tube 415 is driven to rotate and move in the docking tube 414, ensuring that the cutting block 61 can rotate normally, thereby pulling the connecting tube 415 to move toward the outer end, and the inner diameters of the four connecting tubes 415 gradually expand, thereby pulling the four cutting blocks 61 to move toward the outer end.

[0058] During the movement of the four cutting blocks 61 toward the outer end, the second guide frame 51 moves synchronously. Since the two adjacent magnets 54 are in contact with each other, the distance between the four first sliders 56 is kept fixed under the action of the magnetic force of the magnets 54. At this time, the first slider 56 will move down along the second guide frame 51, and the four cleaning plates 55 are always in a state of resistance under the action of the spring 57. At this time, the outer wall of the cutting block 61 contacts the limiting ring at the other end of the connecting rod 52, and the cleaning plate 55 moves down and contacts the ground. The cleaning plate 55 will be located at the opposite end of the cutting knife 62, and the cutting assembly 6 and the cutting knife 62 are driven by the driving motor. The cleaning component 5 rotates, and the cleaning plate 55 rotates to push the cut weeds and soil outward to avoid the presence of weeds, branches and other impurities in the sampling area. After the soil sampling area is cleaned, the cutting block 61 continues to move outward. Since the cutting block 61 contacts the limiting ring at the other end of the connecting rod 52, the cleaning component 5 is driven to move outward synchronously, the two adjacent magnets 54 are disconnected, and the four cleaning plates 55 are out of conflict. The sampling device 1 can be used to perform deep sampling of the ecologically restored soil, effectively preventing weeds from entering the sampling device 1 and affecting the soil sampling effect.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0060] The above is only a preferred embodiment of the present invention.
