DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0025] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0026] Embodiment 1:

[0027] Combination Figure 1-4As shown, this embodiment provides a cross-contamination-proof soil sampling tool, including: a main body module 100.

[0028] Among them, the main body module 100 includes a base plate 110, a bracket 120 installed on the top of the base plate 110, a driving member 130 symmetrically installed on the bracket 120, a movable seat 140 movably arranged in the bracket 120, a mounting seat 150 slidably arranged in the movable seat 140, a moving member 160 installed on one side of the movable seat 140 and fixedly connected to the mounting seat 150, a locking plate 170 symmetrically fixed on both sides of the movable seat 140 and passed through by the bracket 120, a threaded sleeve 180 with one end fixed to the locking plate 170 and the other end sleeved on the driving member 130, and a sampling tube 190 embedded in the mounting seat 150.

[0029] The bottom plate 110 is used to install the bracket 120 to ensure the stability of the bracket 120. A round hole is opened in the middle of the bottom plate 110 to facilitate the sampling tube 190 to pass through and be pressed into the soil. The bracket 120 is used to install other components.

[0030] The movable seat 140 includes a frame 141 movably arranged in the bracket 120 and a cover plate 142 fixed on one side of the top of the frame 141. A slide groove 1411 is opened on the relative inner wall of the frame 141. The mounting seat 150 is slidably arranged in the frame 141, and protrusions 153 are fixed on both sides of the mounting seat 150. The protrusions 153 are slidably engaged in the slide groove 1411 to ensure the stability of the mounting seat 150 in the frame 141. The cover plate 142 is used to limit the sampling tube 190. When the mounting seat 150 is located below the cover plate 142, the cover plate 142 can enable the sampling tube 190 to keep moving synchronously with the movable seat 140.

[0031] The locking plate 170 is fixed to both sides of the frame 141 by bolts. Rectangular grooves 171 are symmetrically opened on the locking plate 170 , and the bracket 120 passes through the rectangular grooves 171 to ensure the stability of the frame 141 moving on the bracket 120 .

[0032] The driving member 130 includes a threaded rod 131 rotatably mounted on the bracket 120 and a motor 132 mounted at the top of the bracket 120 and with its shaft fixedly connected to the threaded rod 131. The threaded rod 131 passes through the threaded sleeve 180, and the threaded rod 131 and the threaded sleeve 180 are meshed with each other, so that when the motor 132 rotates, it can drive the threaded rod 131 to rotate, the rotation of the threaded rod 131 drives the threaded sleeve 180 to move, the movement of the threaded sleeve 180 drives the locking plate 170 to move, the movement of the locking plate 170 drives the movable seat 140 to move, and the movement of the movable seat 140 drives the mounting seat 150 to move synchronously, that is, drives the sampling tube 190 to move up and down, pressed into or removed from the ground, thereby avoiding the trouble of manually pressing the sampling tube 190.

[0033] The movable part 160 is used to facilitate the user to move the position of the mounting seat 150, that is, to facilitate the sampling tube 190 to be placed in the mounting seat 150 or taken out from the mounting seat 150, including a pull rod 161 that is movably arranged through the frame 141 and the end of which is fixed to the mounting seat 150, and a spring 162 that is sleeved on the outside of the pull rod 161 and one end of which is fixed to the mounting seat 150 and the other end is fixed to the inner wall of the frame 141. The pull rod 161 is used to facilitate the user to pull the mounting seat 150 to move, and the spring 162 is used to keep the mounting seat 150 always under the cover 142.

[0034] The sampling tube 190 is embedded in the mounting base 150, which serves as both a sampling tool and a storage tool, including a tube body 191, a bottom sealing cover 192 installed at the bottom end of the tube body 191 through a threaded connection, and a top sealing cover 193 installed at the top end of the tube body 191 through a threaded connection. The tube body 191 is used to sample soil and store samples. Inverted rings 1911 are fixed in an array on the inner wall of the tube body 191. The cross-section of the inverted ring 1911 is a right triangle and faces directly toward the top sealing cover 193, which can effectively prevent the soil from falling from the tube body 191 during the process of moving the tube body 191 out of the ground. The bottom sealing cover is used to seal the bottom end of the tube body 191 to prevent the soil sample from falling. The top sealing cover 193 is used to seal the top end of the tube body 191, and at the same time facilitates the subsequent pouring of the soil in the tube body 191 from the top of the tube body 191.

[0035] In addition, a through hole 151 is opened on the mounting seat 150, and the diameter of the through hole 151 is equal to the outer diameter of the sampling tube 190, which is convenient for the tube body 191 to pass through the mounting seat 150. Grooves 152 are opened in a circular array on the inner wall of the through hole 151, and protrusions 1931 are fixed in a circular array on the outer surface of the top sealing cover 193. The protrusions 1931 are embedded in the grooves 152, which can ensure that the tank body is stably embedded in the mounting seat 150.

[0036] The working principle and use process of the utility model are as follows: when in use, unscrew the bottom sealing cover 192 of the sampling tube 190, pull the pull rod 161, drive the mounting seat 150 to move out from under the cover plate 142 in the frame 141, pass the sampling tube 190 through the mounting seat 150, make the protrusion 1931 on the top sealing cover 193 fit into the groove 152, loosen the pull rod 161, and under the action of the spring 162, drive the mounting seat 150 to move to the cover plate 142 in the frame 141 and lower it. At this time, the motor 132 starts, drives the threaded rod 131 to rotate, and the rotation of the threaded rod 131 drives the threaded sleeve 180 to move, and the threaded sleeve 180 moves through the locking plate 17 0 drives the movable seat 140 to move downward, and the movable seat 140 moves downward to drive the sampling tube 190 to move downward and press into the soil to sample the soil. After the sampling is completed, the motor 132 drives the threaded rod 131 to rotate and drive the threaded sleeve 180 to reset, that is, drives the movable seat 140 to move upward, and the movable seat 140 moves upward to drive the sampling tube 190 to move upward and reset. At this time, pull the pull rod 161 again to move the mounting seat 150 out from under the cover plate 142 in the frame 141, take out the sampling tube 190 in the mounting seat 150, screw the bottom sealing cover 192 into the bottom end of the tube body 191, and the sampling can be completed. After that, a new sampling tube 190 can be replaced to sample again.

[0037] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
