[0019] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0020] In the description of this invention, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0024] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0025] As shown in the accompanying drawings, a soil sampler for mineral exploration includes an operating rod 1 and a sampling head 2, wherein the sampling head 2 is disposed at the lower end of the operating rod 1; it also includes an ejection assembly and a sealing assembly. The ejection assembly includes a push plate 14 and an ejection spring 5. The sampling head 2 is provided with an axial sampling cavity 13. One end of the ejection spring 5 is fixedly connected to the bottom of the sampling cavity 13, and the other end is fixedly connected to the push plate 14. The sealing component is installed inside the sampling head 2. When the soil sample in the sampling chamber 13 drives the push plate 14 to reach the set position, the push plate 14 drives the sealing component to seal the bottom of the sampling chamber 13.

[0026] In another embodiment of the present invention, the sealing assembly includes a transmission mechanism, a locking mechanism, and a sealing mechanism. One end of the transmission mechanism is connected to the push plate 14, and the other end is connected to the locking mechanism. The locking mechanism is used to limit the sealing mechanism. When the soil sample in the sampling chamber 13 drives the push plate 14 to the set position, the push plate 14 drives the transmission mechanism to operate, thereby driving the locking mechanism to release the limit on the sealing mechanism.

[0027] The transmission mechanism includes a locking block 7, a connecting rod 8, and a transmission rod 16. The sampling head 2 and the operating rod 1 are provided with movable holes for the connecting rod 8 to move. The locking block 7 is located at the upper end of the connecting rod 8. The operating rod 1 is provided with a movable groove 6 for the locking block 7 to move. One side of the locking block 7 extends into the sampling chamber 13. The transmission rod 16 is located at the lower end of the connecting rod 8 and is connected to the locking mechanism.

[0028] In this embodiment, the locking mechanism further includes a locking block 20, a locking spring 23, and a gear 18. The sampling head 2 is provided with a mounting groove 22 for mounting the locking mechanism. One end of the locking spring 23 is fixedly connected to the locking block 20, and the other end is fixedly connected to the bottom of the mounting groove 22. The gear 18 is rotatably disposed in the sampling head 2. The transmission rod 16 is provided with a plurality of transmission teeth 17 that mesh with the gear 18. The locking block 20 is provided with a plurality of transmission teeth 21 that mesh with the gear 18. The sealing mechanism is provided with a locking groove 19 that cooperates with the locking block 20.

[0029] The sealing mechanism includes a sealing plate 24 and a driving component. The locking mechanism is used to position the driving component, and the driving component is used to drive the sealing plate 24 to seal the lower end of the sampling chamber 13. Specifically, the driving component includes a driving spring 10, a driving block 11, and a transmission mechanism two. The sampling head 2 is provided with a mounting cavity 9 for mounting the driving spring 10 and the driving block 11. One end of the driving spring 10 is fixedly connected to the bottom of the mounting cavity 9, and the other end is fixedly connected to the driving block 11. The driving block 11 is drivenly connected to the transmission mechanism two, and the transmission mechanism two is drivenly connected to the sealing plate 24.

[0030] Furthermore, the second transmission mechanism includes a second gear 29, a first rotating shaft 30, a third gear 26, a second rotating shaft 27, and a drive rod 12. The second gear 29 is mounted on the first rotating shaft 30, which is rotatably mounted inside the sampling head 2. The third gear 26 is mounted on the second rotating shaft 27, which is rotatably mounted inside the sampling head 2. The first rotating shaft 30 and the second rotating shaft 27 are driven by a chain 28. The third gear 26 is connected to the sealing plate 24. One end of the drive rod 12 is fixedly connected to the drive block 11, and the other end is provided with several transmission teeth 31 that mesh with the second gear 29. The sealing plate 24 is provided with several transmission teeth 25 that mesh with the third gear 26.

[0031] Specifically, the sealing plate is installed as follows: an inclined groove is provided on the sampling head 2, the sealing plate 24 is movably installed in the inclined groove, the inclined groove is connected to the sampling chamber 13, and an inclined positioning groove 15 is provided on the side of the sampling chamber 13 away from the inclined groove.

[0032] In the above scheme, when the sampler is inserted into the mineral to be sampled, the sample enters the sampling chamber from the bottom of the sampling head, causing the push plate to move upward until the push plate contacts the locking block, causing the locking block to move upward. The locking block drives the connecting rod and the transmission rod to move upward, which in turn drives gear one to rotate. During the rotation of gear one, the locking block disengages from the locking groove and retracts into the installation groove. The driving block moves downward under the action of the driving spring, which in turn drives the driving rod to move downward, causing gear two and gear three to rotate. During the rotation of gear three, the sealing plate extends out from the inclined groove and enters the sampling chamber until one end of the sealing plate is locked into the positioning groove, and the lower end of the sampling chamber is sealed. The above scheme achieves two objectives. First, the ejection component drives the transmission mechanism during sampling, thereby unlocking the driving component by contacting the locking mechanism. This allows the sealing component to seal the lower end of the sampling chamber after the push plate moves to the designated position, effectively preventing the sample from falling out of the sampling chamber after sampling. Second, the force applied to the ejection spring during sampling compresses the spring after sampling. After the sealing component opens, the sample in the sampling chamber can be ejected from the sampling chamber under the action of the ejection spring and the push plate, facilitating sample removal and reducing sample adhesion to the cavity wall.

[0033] In order to facilitate the reset of the drive block and enable the locking mechanism to lock the drive block, a reset block 3 is provided on the side of the drive block 11. The sampling head 2 is provided with a reset groove 4 for the reset block 3 to move. After sampling, the reset block is pushed upward, which in turn drives the drive block to move upward and compress the drive spring until the position of the locking groove on the drive block is aligned with the position of the locking block. Under the action of the locking spring, the locking block extends out of the mounting groove and is inserted into the locking groove.

[0034] The above description only illustrates the preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
