DETAILED DESCRIPTION

[0021] Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the scope of the utility model protection.

[0022] As Figures 1-6 shown, a special sampling drill for sandy soil includes a main rod 1, a first handle 2 is rotatably connected to the top end of the main rod 1 through a bearing, a driving device 3 is fixedly installed on the lower side of the first handle 2, the driving device 3 is connected to the main rod 1 through a transmission structure, and the driving device 3 can drive the main rod 1 to rotate through the transmission structure. The driving device 3 mainly includes a servo motor and a driving gear, and a driven gear is also arranged on the outer side of the main rod 1, wherein the above transmission process is prior art and will not be described in detail. The main rod 1 is fixedly connected with an insertion rod 4 at the lower end, a collecting cylinder 5 is arranged below the main rod 1, a connecting rod 6 is arranged inside the collecting cylinder 5, and the upper end of the connecting rod 6 is inserted with the insertion rod 4.

[0023] A sleeve 7 is sleeved on the lower part of the main rod 1, a vertically extending guide protrusion 8 is arranged on the main rod 1, and a groove 9 corresponding to the guide protrusion 8 is arranged on the inner wall of the sleeve 7. A limiting hole is formed in the main rod 1, a fastening bolt 10 corresponding to the limiting hole is threadedly connected to the sleeve 7, and the fastening bolt 10 can be inserted into the limiting hole on the main rod 1 through the threaded hole in the sleeve 7 to limit the position. A top cover 11 corresponding to the collecting cylinder 5 is fixedly arranged at the lower end of the sleeve 7, and a limiting assembly is sleeved on the sleeve 7. A connecting bolt 12 is installed on the connecting rod 6, and a connecting screw hole corresponding to the connecting bolt 12 is formed in the lower side of the insertion rod 4; when the insertion rod 4 is inserted into the connecting rod 6, the insertion rod 4 is fixedly connected by screwing the connecting bolt 12 into the connecting screw hole.

[0024] The limiting assembly includes a pair of limiting plates 13 sleeved on the outer side of the sleeve 7, the pair of limiting plates 13 are connected through a hinge, screw holes are formed at the four corner positions of the unfolded limiting plates 13, vertically downward positioning nails 14 are threadedly connected to the screw holes, second handles 15 are arranged on each limiting plate 13, and a circular hole through which the sleeve 7 passes is formed between the two limiting plates 13. The collecting cylinder 5 and the top cover 11 are both conical, the bottom of the collecting cylinder 5 is tapered, and the middle part of the top cover 11 is arched upward to form a taper.

[0025] It should be noted that in use, the operator can spread a pair of limiting plates 13, and screw the positioning nails 14 into the threaded holes on the limiting plates 13, and then set the limiting plates 13 outside the sleeve 7, and then set the sleeve 7 and the limiting assembly outside the main rod 1, at this time, the plug rod 4 is inserted with the connecting rod 6, and the collecting cylinder 5 is fixed on the lower side of the main rod 1 through the connecting bolt 12, and then the top cover 11 on the lower side of the sleeve 7 is made to adhere to the upper side of the collecting cylinder 5 through the cooperation and sliding of the guide protrusion 8 and the groove 9, so that the inside of the collecting cylinder 5 becomes a closed space, when the top cover 11 adheres to the collecting cylinder 5, the limiting hole cooperates with the fastening bolt 10, the position of the sleeve 7 is fixed, and the connection tightness of the collecting cylinder 5 and the top cover 11 is increased.

[0026] At this time, the operator preliminarily inserts the collecting cylinder 5 into the soil, and inserts the positioning nails 14 on the limiting plates 13 into the soil by holding a pair of second handles 15 and pushing downward, and then the operator can hold the first handle 2 and control the driving device 3 to operate, when the servo motor operates, it can drive the main rod 1, the sleeve 7, the top cover 11 and the collecting cylinder 5 to rotate, so that the collecting cylinder 5 can be drilled into the sand soil to take samples, and a pair of limiting plates 13 still stay on the surface of the sand soil, which can limit the position of the sleeve 7 to prevent it from deviating and shaking, and increase the stability of the vertical descent of the main rod 1 and the sleeve 7.

[0027] After reaching the specified depth, the operator can remove the fastening bolt 10, and pull the sleeve 7 upward by using a pair of temporarily screwed third handles 16 to separate the top cover 11 from the collecting cylinder 5, the third handle 16 is detachably installed, the end of the third handle 16 is provided with a thread, and is fixed by screwing into the threaded hole of the sleeve 7. The upper side of the top cover 11 is conical, which can reduce the resistance when pulling the top cover 11, and facilitate the separation of the top cover 11 from the collecting cylinder 5, and then the soft soil will flow into the inside of the collecting cylinder 5, thereby completing the sampling operation of the sand soil at this depth;

[0028] After the sampling operation is completed, the operator pulls out the positioning nails 14, and then pulls the main rod 1 upward to take out the sleeve 7, the top cover 11 and the collecting cylinder 5 from the sand soil. At this time, since the collecting cylinder 5 is full of sand, there is no need to worry that the sand at the remaining depth will enter the inside of the collecting cylinder 5 during the removal of the device, affecting the sampling result; then the connecting rod 6 and the plug rod 4 are separated, and the collecting cylinder 5 is removed, which is convenient for subsequent processing of the sand sample in the collecting cylinder 5.

[0029] The limiting plate 13 is provided with a flexible ring 18 for tightly fitting the removed positioning nail 14, and the positioning nail 14 can be inserted into the flexible ring 18 after being removed to prevent loss. A pair of limiting plates 13 are connected by hinges, and the hinges are 180-degree hinges, which can be folded to reduce the volume of the pair of limiting plates 13, and facilitate the operator to carry.

[0030] A reinforcing sheet 17 is arranged on the connecting rod 6, and one side of the reinforcing sheet 17 is connected with the inner wall of the collecting cylinder 5, so as to increase the connecting strength between the connecting rod 6 and the collecting cylinder 5. The device needs to be equipped with a storage battery or a small generator to supply power for the driving device.

[0031] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
