[0019] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0020] Combined with Figures 1 to 3 The sampling device for farmland transformation comprises an L-shaped support plate 1, and four support mechanisms 4 are distributed in an array on the bottom side of the L-shaped support plate. An up-and-down moving mechanism 2 is provided on the vertical side of the L-shaped support plate 1, and a sampling mechanism 3 is installed on the right side of the up-and-down moving mechanism 2, and a pushing mechanism 6 is provided on the sampling mechanism 3.

[0021] The four supporting mechanisms 4 include an internally threaded sleeve 41, a threaded column 42 and a supporting seat 43. Four internally threaded sleeves 41 are fixed to the lateral bottom side of the L-shaped supporting plate 1. The interiors of the four internally threaded sleeves 41 are respectively threadedly connected with four threaded columns 42. The bottom ends of the four threaded columns 42 are all fixed with supporting seats 43. The supporting seat 43 is rotated to make the supporting seat 43 drive the threaded column 42 to rotate, so that the threaded column 42 moves along the internally threaded sleeve 41, and then the supporting seat 43 stably supports the L-shaped supporting plate 1.

[0022] The up-and-down moving mechanism 2 includes a rectangular through hole 21, a handle 22 and a slider 23. A rectangular through hole 21 is opened on one vertical side of the L-shaped support plate 1. The inner side of the rectangular through hole 21 is slidably connected with a slider 23. Two handles 22 are fixed on the left side of the slider 23. The user steps on the horizontal surface of the L-shaped support plate 1 and holds the handle 22, thereby moving the slider 23 up and down along the rectangular through hole 21, which is convenient for the up and down movement of the sampling mechanism 3.

[0023] The sampling mechanism 3 includes an L-shaped mounting block 31, a motor 32, a gear 1 33, a sampling barrel 34 and a gear 2 35. The L-shaped mounting block 31 is fixedly mounted on the right side of the slider 23. The motor 32 is mounted on the lateral upper surface of the L-shaped mounting block 31. The output shaft of the motor 32 is provided with a gear 1 33. The L-shaped mounting block 31 is laterally connected with a sampling barrel 34 through a bearing. The side of the sampling barrel 34 is mounted with a gear 2 35, and the gear 2 35 is meshed with the gear 1 33. After the L-shaped mounting block 31 moves with the slider 23, the motor 32 works, so that the motor 32 drives the gear 1 33 to rotate, and the rotation of the gear 1 33 drives the gear 2 35 to rotate. The rotation of the gear 2 35 causes the sampling barrel 34 to rotate, and then the sampling barrel 34 rotates to contact the soil, so that the sampling barrel 34 can enter under the ground for sampling.

[0024] The pushing mechanism 6 includes a pushing block 61, a connecting column 62 and a pushing handle 63. The pushing block 61 is sleeved inside the sampling tube 34. One end of the connecting column 62 is fixed to the upper surface of the pushing block 61. The other end of the connecting column 62 passes through the top of the sampling tube 34. The other end of the connecting column 62 is fixed with a pushing handle 63. Pressing the pushing handle 63 causes the pushing handle 63 to drive the connecting column 62. The connecting column 62 causes the pushing block 61 to move along the inside of the sampling tube 34, thereby facilitating the removal of the sample soil inside the sampling tube 34.

[0025] The L-shaped support plate 1 is hinged with a U-shaped steel wire 5 on the vertical left side. The U-shaped steel wire 5 rotates to fit the handle 22 , so as to fix the slider 23 inside the rectangular through hole 21 , so as to facilitate the removal of the sampling tube 34 .

[0026] An exhaust hole 7 is provided at the top of the inner part of the sampling tube 34. The exhaust hole 7 allows the gas inside the sampling tube 34 to be discharged along the exhaust hole 7 during the operation of the pushing mechanism 6, thereby preventing the air pressure inside the sampling tube 34 from affecting the sampling of the sampling tube 34. A thread is provided on the outer side of the sampling tube 34, and the bottom end of the sampling tube 34 is serrated, and the front side surface of the serrations is a slope facing outward in sequence. During the rotation and friction between the front of the serrations and the soil, the soil is moved outward and moved out along the outer thread of the sampling tube 34, thereby preventing the soil from entering the interior of the sampling tube 34 when the end of the sampling tube enters the ground, and does not affect the detection accuracy of the soil inside the sampling tube.

[0027] The sampling device for farmland transformation described above, when in use, rotates the support seat 43, so that the support seat 43 drives the threaded column 42 to rotate, so that the threaded column 42 moves along the internal threaded sleeve 41, so that the support seat 43 stably supports the L-shaped support plate 1, the user steps on the horizontal surface of the L-shaped support plate 1, and holds the handle 22, so that the slider 23 moves up and down along the rectangular through hole 21, and after the L-shaped mounting block 31 moves with the slider 23, the motor 32 works, so that the motor 32 drives the gear 1 33 to rotate, and the rotation of the gear 1 33 drives the gear 2 35 to rotate, and the rotation of the gear 2 35 causes the sampling tube 34 to rotate, so that the sampling tube 34 rotates and contacts the soil, so that the sampling tube 34 can enter under the ground for sampling, and then the U-shaped steel wire 5 rotates, By sleeve-joining the U-shaped steel wire 5 on the handle 22, the slider 23 can be fixed inside the rectangular through hole 21, and the push handle 63 is pressed to make the push handle 63 drive the connecting column 62, and the connecting column 62 makes the push block 61 move along the inside of the sampling tube 34, thereby facilitating the removal of the sample soil inside the sampling tube 34. The exhaust hole 7 can make the gas inside the sampling tube 34 be discharged along the exhaust hole 7 during the operation of the pushing mechanism 6, so as to avoid the influence of the air pressure inside the sampling tube 34 on the sampling of the sampling tube 34. During the rotation and friction between the front of the sawtooth and the soil, the soil is moved outward and removed along the outer thread of the sampling tube 34, so as to prevent the soil from entering the inside of the sampling tube 34 when the end of the sampling tube enters the ground, without affecting the detection accuracy of the soil inside the sampling tube.

Although the present invention is specifically demonstrated and introduced in conjunction with the preferred implementation scheme, there are many methods and ways to implement the technical solution.
