DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1

[0019] Reference Figure 1-3 A roadbed compaction detection device includes a chassis 1, on which four threaded columns 9 are threadedly connected. The front ends of the four threaded columns 9 are all provided with pointed heads, so that the threaded columns 9 can be easily inserted into the ground when rotating.

[0020] The four threaded columns 9 are all fixedly connected with the second gear 7, and the chassis 1 is rotatably connected with four first gears 6 through bearings. The first gear 6 is meshed with the second gear 7. A two-way telescopic rod 8 is fixedly connected to the chassis 1, and a rack 5 is meshed with the four first gears 6. Two parallel racks 5 are fixedly connected by a connecting plate 12, and the two connecting plates 12 are respectively fixedly connected to the two-way telescopic rod 8. A cutter 10 is connected to the chassis 1 through an adjusting mechanism. By adopting the two-way telescopic rod 8, the rack 5 is driven to move, thereby causing the first gear 6 to rotate, thereby driving the second gear 7 to rotate, and driving the threaded column 9 to rotate. The four threaded columns 9 are inserted into the ground at the same time, which is conducive to the convenience of operation and prevents the chassis 1 from moving.

[0021] The adjusting mechanism includes a telescopic rod 4, the telescopic rod 4 is fixedly connected to a connecting plate 3, the connecting plate 3 is fixedly connected to a motor 2, the motor 2 is drivably connected to a rotating shaft 11, and the rotating shaft 11 is fixedly connected to a cutter 10. By rotating the motor 2, the rotating shaft 11 is driven to rotate, thereby driving the cutter 10 to rotate, cutting and loosening the soil, taking out the soil, and performing a solidity test. The telescopic rod 4 plays a lifting role so as to control and adjust the excavation depth.

[0022] When in use, the bidirectional telescopic rod 8 is extended and retracted, which will drive the rack 5 to move, thereby causing the first gear 6 to rotate, thereby driving the second gear 7 to rotate, driving the threaded column 9 to rotate, and inserting the four threaded columns 9 into the ground at the same time. Then the motor 2 rotates, which will drive the rotating shaft 11 to rotate, thereby driving the cutter 10 to rotate, cutting and loosening the soil, and taking out the soil for compaction detection.

[0023] Example 2

[0024] In the first embodiment, since the cutter is located directly above the hole of the chassis 1, when taking out the soil, the hand may easily touch the cutter 10, resulting in injury to the hand. Figure 1-3 As another preferred embodiment of the utility model, on the basis of embodiment 1, a slider 14 is fixedly connected to the telescopic rod 4, a slide groove 13 is provided on the chassis 1, and the slider 14 can be slidably set in the slide groove 13. By adopting the design of the slider 14 and the slide groove 13, the position of the telescopic rod 4 can be adjusted and moved, driving the slider 14 to move in the slide groove 13, so that the cutter 10 is offset to the top of the hole of the chassis 1, which is beneficial to the safety when the soil is taken out.

[0025] Example 3

[0026] In Example 2, when soil cutting is performed, it is easy for the equipment to move. Figure 1-3As another preferred embodiment of the utility model, on the basis of embodiment 2, the telescopic rod 4 is positioned by a positioning mechanism, the positioning mechanism includes a threaded sleeve 15, the threaded sleeve 15 is fixedly connected to the chassis 1, the telescopic rod 4 is fixedly connected with a connecting ear 17, the connecting ear 17 is threadedly penetrated with a threaded rod 16, the threaded rod 16 is threadedly connected to the threaded sleeve 15, and the threaded sleeve 15 is matched with the threaded rod 16 to fix the position of the telescopic rod 4, thereby preventing the telescopic rod 4 from moving during soil excavation.

[0027] A connecting tube is sleeved on the rotating shaft 11, and the connecting tube is fixedly connected to the cutter 10. The connecting tube is fixedly connected to the rotating shaft 11 by screws. By adopting the design of screws and the connecting tube, the connecting tube can be disassembled and the cutter 10 can be replaced and maintained.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
