In addition, the forms of the various structures described in the following embodiments are merely illustrative. The soil pollution detection device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figures 1 to 5 The present invention provides a soil pollution detection device, including a chassis assembly 1, the chassis assembly 1 including a base frame 11 and a motion assembly 12, the base frame 11 and the motion assembly 12 being movably connected, an electrical control box 13 being fixedly installed on the inner wall of the base frame 11, and also including a frame assembly 3.

A protective cover 33 is fixedly installed on the side of the outer shell 31. A perforated plate 34 is movably installed on the inner wall of the middle part of the side of the outer shell 31. Several return springs 36 are fixedly connected between the perforated plate 34 and the outer shell 31. A limit post 35 is movably sleeved on the side of the perforated plate 34. The other end of the limit post 35 is movably sleeved on the inner wall of the outer shell 31. A support plate 37 is fixedly installed on the inner side of the outer shell 31.

A distributing assembly 5 is movably connected to the bottom of the inner wall of the base frame 11. It also includes a conveying device 6, which is installed inside the housing 31, and a detection drilling assembly 7, which is installed inside the housing 31.

[0020] In this embodiment, after the soil falls onto the sluice plate 34, the eccentric wheel 69 is driven by the meshing of the sixth gear 66 and the seventh gear 67 and the transmission of the striking rod 68 to continuously strike the bottom of the sluice plate 34. Then, the sluice plate 34 is reset by the reset spring 36, making it easier for the soil on the sluice plate 34 to fall onto the conveyor belt 65, thus preventing the device from becoming clogged.

[0021] refer to Figure 6 and Figure 9 The feeding assembly 4 includes a drilling column 41 movably sleeved on the inner wall of the base frame 11, a material taking assembly 46 fixedly connected to the top of the protective cover 33, a second motor 49 and a spiral blade 43 installed on the inner wall of the bottom of the drilling column 41.

[0022] In this embodiment, the first gear 44 is driven to rotate by the second gear 48 and the first chain 47. The structure of the first threaded rod 45 is similar to that of the threaded sliding rod assembly 74. The rotation of the first gear 44 drives the first threaded rod 45 to rotate through the pulley. Then, the thread on the upper part of the first threaded rod 45 meshes with the inner wall of the material taking assembly 46, causing the first threaded rod 45 to move downward, which in turn drives the drilling column 41 to move downward. By setting the parameters of the device, the number of rotations of the first threaded rod 45 is set so that the inclined plate on the wall of the drilling column 41 can always be in the same vertical plane as the perforated plate 34 after the drilling column 41 has moved.

The other end of the first drive shaft 468 is movably sleeved on the inner wall of the drilling column 41.

[0024] In this embodiment, while the second motor 49 rotates, it can simultaneously drive the spiral blades 43 to rotate, transporting the soil to the top. It can also drive the paddle plate 465 to paddle the soil into the device, and simultaneously drive the soil cover 467 to rotate. This eliminates the need to open the soil cover 467 before soil collection.

A fixed bearing 72 is movably sleeved at the bottom of the threaded sliding rod assembly 74, and a detector 71 is movably sleeved on the outside of the fixed bearing 72. The top of the detector 71 is fixedly connected to the bottom of the limiting rod 73. An eighth gear 75 is movably sleeved on the side of the threaded sliding rod assembly 74.

[0027] refer to Figure 7 The threaded sliding rod assembly 74 includes a sliding rod 741 that is movably sleeved on the inner wall of the bearing sleeve 2. A sliding groove 743 is provided on the outer surface of the sliding rod 741. Several pulleys 742 are movably installed at the sliding groove 743. The outer side of the pulley 742 is movably sleeved with the inner wall of the eighth gear 75, and the inner side of the pulley 742 is movably sleeved with the sliding groove 743.

[0029] refer to Figure 4 The material distribution assembly 5 includes a support bearing 55 movably sleeved on the bottom of the inner wall of the base frame 11 and a third motor 54 fixedly installed on the bottom of the inner wall of the base frame 11. A soil hopper 51 is fixedly installed on the top of the support bearing 55, and an external screw 52 is fixedly installed on the outside of the soil hopper 51. A fifth gear 53 is fixedly connected to the top of the third motor 54, and the fifth gear 53 and the external screw 52 mesh.

[0030] The working principle of this invention: When the operator moves the remote control device to the designated soil collection and testing location, the electrical control box 13 receives the collection and testing command, and the fourth motor 39 starts, driving the second transmission shaft 78 to rotate. The second transmission shaft 78 drives the ninth gear 77 and the second gear 48 to rotate. The ninth gear 77 drives the threaded sliding rod assembly 74 to rotate through the third chain 76 and the eighth gear 75. Since the threaded sliding rod assembly 74 meshes with the inner thread of the bearing sleeve 2, and through the action of the pulley 742, the threaded sliding rod assembly 74 will push the detector 71 downward to approach. The conveyor belt detects soil on it. The second gear 48, via the first chain 47 and the first gear 44, drives the first threaded rod 45 to rotate. The first threaded rod 45 drives the drilling column 41 to rotate downwards, drilling it into the ground. The drilling depth can be set. When the set depth is reached, the second motor 49 starts, driving the blade support rod 461 to rotate. The blade support rod 461 drives the spiral blade 43 and the third gear 462 to rotate. The third gear 462, via the second chain 463 and the fourth gear 464, drives the first drive shaft 468. The first drive shaft 468 rotates, driving the paddle plate 465 to rotate and push the soil into the device. The soil passes through the inclined plate and enters the soil cylinder 42. After being rotated by the spiral blades 43, the soil rises to the inclined plate located on the inner wall of the drilling column 41. The soil falls onto the perforated plate 34. Then, the first motor 38 starts, driving the first conveyor rod 61 to rotate. The first conveyor rod 61 drives the first conveyor wheel 62 and the sixth gear 66 to rotate. The sixth gear 66 drives the eccentric wheel 69 to perform eccentric motion through the seventh gear 67 and the striking rod 68. The eccentric wheel 69 continuously strikes the perforated plate 34. After being reset by the reset spring 36, the soil on the sluice plate 34 can fall smoothly onto the conveyor belt 65. The first conveyor rod 61 drives the conveyor belt 65 to rotate through the first conveyor wheel 62, and the soil will be dispersed on the conveyor belt 65. The detector 71 will perform a preliminary detection on the soil. The third motor 54 located on the base frame 11 will drive the fifth gear 53 to move intermittently. The fifth gear 53 then drives the soil bin 51 to rotate by meshing with the external screw gear 52, so that the soil collected at different depths and positions falls into different storage tanks to complete the collection.

[0031] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
