[0014] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See also Figures 1 to 4 As shown, the present embodiment involves a soil sampling device for geological survey, comprising a platform plate 2 with a center hole 1, the platform plate 2 being fixedly connected with nails 3 arranged in a circular array around the axis of the center hole and extending downward, a lead screw 4 passing through the center hole 1, a lead screw nut 5 being threadedly connected to the lead screw 4, the lead screw nut 5 being fixedly connected to the platform plate 2, the lower end of the lead screw 4 being provided with a follow-up sampler 6, the lead screw 4 being sawed to form two defective portions 7 with an interval angle of 180°, the defective portion 7 extending along the axial direction of the lead screw 4, a sleeve 8 being slidably connected to the lead screw 4, the inner wall of the sleeve 8 being provided with a limiting portion 9 matching the defective portion, the outer wall of the sleeve 8 being provided with two side tubes 10 with an interval angle of 180° and extending radially, one of the side tubes 10 having a turning rod 11 inserted therein.

[0018] Furthermore, the angles between two adjacent nails 3 are equal.

[0019] In this embodiment, the soil sampling device is first moved to the sampling position, and then an external tool is used to hammer the nail 3 until its tip is inserted into the soil to complete the suspension and fixation of the platform plate 2. Then, the turning rod 11 inserted into the side tube 10 is used to rotate, so that the screw 4 and the sampler 6 are rotated. The fixed screw nut 5 is used for transmission, and the sampler 6 moves down and contacts the soil. The sampler 6 that continues to move down will be inserted into the soil, and finally the soil sampling operation is completed.

[0020] Among them, by coordinating the defective portion 7 with the limiting portion 9, the sleeve 8 can only move axially relative to the screw 4 and cannot rotate circumferentially relative to the screw 4, which makes it convenient to drive the screw 4 to rotate when the sleeve 8 is turned.

[0021] Example 2

[0022] See also Figures 1 to 4 As shown, the soil sampling device for geological survey involved in this embodiment is further configured on the basis of Example 1, wherein a row of positioning grooves 12 arranged at intervals along the length direction are provided in the defective portion 7, and a ball head plunger 13 is threadedly connected to the sleeve 8, and the ball head of the ball head plunger 13 is embedded in the positioning groove 12.

[0023] In this embodiment, the positioning groove 12 cooperates with the ball plunger 13 to provide a limit position. When the lead screw 4 moves downward until the sleeve 8 is close to the platform 2, the hand driving the trigger rod 11 to rotate will contact the platform 2, affecting the operation. At this time, the sleeve 8 can be appropriately moved upward to restore the operating space.

[0024] The sleeve 8 that can be moved up and down and positioned also has a height adjustment function, so it can be used by people of different heights without bending over.

[0025] Example 3

[0026] See also Figures 1 to 4 As shown, the soil sampling device for geological survey involved in this embodiment is further configured on the basis of Examples 1 and 2, wherein the nail 3 has a tail end portion 301 , and the tail end portion 301 is arranged above the platform plate 2 .

[0027] In this embodiment, the tail end portion 301 is arranged above the platform plate 2 to facilitate hammering, so as to fix the platform plate 2 .

[0028] The soil sampling device for geological survey involved in the utility model first fixes and suspends the platform plate above the soil by using nails, and then drives the lead screw to rotate. Through thread transmission, the sampler gradually moves down and is inserted into the soil for sampling. The manual operation is convenient, the soil can be easily inserted, the overall function is complete, and the practicability is strong.

Therefore, the terms describing orientation or positional relationship in the present invention are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, they can combine the embodiments and understand the specific meanings of the above terms according to specific circumstances.
