[0026] Embodiment 1

[0027] like Figure 1-Figure 3 As shown, the concrete sampler for concrete testing proposed by the utility model comprises a base 1, a fixing part, a transmission part 12, a lifting part 8, a threaded rod 9, a rotating handle 10, a sliding part 13 and a shovel plate 14;

[0028] The top of the base 1 is connected to the lifting part 8; the top of the lifting part 8 is threadedly connected to the threaded rod 9; the top of the threaded rod 9 is connected to the rotating handle 10; a drill bit 11 is provided on the bottom of the threaded rod 9; a wear-resistant layer is provided on the outer end surface of the drill bit 11; the top of the base 1 is slidably connected to the sliding member 13, a through hole is provided at the center of the base 1, a connecting rod is provided on the bottom of the sliding member 13, and the bottom side of the connecting rod is connected to the shovel plate 14, and multiple groups of sliding members 13 and shovel plates 14 are distributed in mirror symmetry.

[0029] The fixed part includes a rotating bracket 2, a rotating shaft 3, a rotating connecting rod 4, a rotating connecting piece 5, a counterweight 6 and a ground nail 7; the rotating bracket 2 is connected to the base 1, and a plurality of groups of rollers are provided on the bottom of the base 1; the side of the rotating bracket 2 is rotatably connected to the rotating shaft 3; the end of the rotating shaft 3 away from the rotating bracket 2 is rotatably connected to the rotating connecting rod 4, and the end of the rotating connecting rod 4 away from the rotating shaft 3 is rotatably connected to the rotating connecting piece 5; the bottom of the rotating connecting piece 5 is connected to the counterweight 6, and a ground nail 7 is provided on the bottom of the counterweight 6; multiple groups of fixing parts are symmetrically arranged on both sides of the base 1.

[0030] The lifting part 8 includes a telescopic rod and a threaded transmission part. The bottom of the telescopic rod is connected to the base 1 ; the output end of the top of the telescopic rod is transmission-connected to the threaded transmission part, and the threaded transmission part is threadedly connected to the threaded rod 9 .

[0031] The transmission part 12 includes a lifting bracket, a symmetrical transmission rod and a transmission connecting piece. The lifting bracket is arranged on the top of the lifting part 8. The side of the lifting bracket is rotatably connected to the symmetrical transmission rod. The end of the symmetrical transmission rod away from the lifting bracket is rotatably connected to the transmission connecting piece. The transmission connecting piece is connected to the top of the sliding piece 13.

[0032] A sliding groove is provided on the top of the base 1, a sliding protrusion is provided on the bottom of the sliding member 13, the sliding groove is slidably connected with the sliding protrusion, a sliding stopper is provided on the side of the inner wall of the sliding groove, and the sliding stopper contacts the side of the sliding protrusion.

[0033] A plurality of brake devices are arranged on the bottom of the base 1, and the plurality of brake devices are connected with the side rotation damping of the roller.

[0034] A side baffle is provided on the side of the shovel plate 14, a slope is provided on the top of the shovel plate 14, and the height of the shovel plate 14 is the same as the height of the roller.

[0035] In this embodiment, the sampling efficiency of concrete can be effectively improved by this device. Compared with traditional devices, this device is easier to move and fix during the sampling process. Therefore, when multiple groups of equally spaced samples are required, the use efficiency of this device is higher and the positioning accuracy of multiple sampling points is higher.

[0036] When the device is in working state, the base 1 can be pushed to move the device on the concrete surface. When the device moves to the specified position, the ground nails 7 can be brought into contact with the ground by rotating the rotating connecting rods 4 on both sides. Hammering the ground nails 7 downward can facilitate the fixation of the device in an outdoor environment. The structure of the counterweight 6 can prevent the ground nails 7 from tilting and loosening. The rotating combined structure of the rotating shaft 3 and the rotating connecting rod 4 can fold the ground nail 7 structure upward during movement, thereby ensuring the stability of the device during movement and avoiding unnecessary wear of the ground nail 7 structure. When in a fixed state, lowering the ground nail 7 structure can achieve a fixing effect.

[0037] When the device is in a fixed state, the telescopic rod inside the lifting part 8 descends, so that the drill bit 11 contacts the ground. Through the structure of the transmission part 12, the sliding member 13 slides away from each other on both sides, thereby avoiding the shovel plate 14 from blocking the drill bit 11. At this time, the drill bit 11 can be driven by rotating the handle 10 to rotate downward, thereby generating concrete debris on the concrete surface, which is convenient for extracting samples. After the drill bit 11 is crushed and sampled, the telescopic rod of the lifting part 8 extends upward. At this time, the drill bit 11 is away from the ground. At the same time, the sliding member 13 moves closer to each other under the drive of the transmission part 12, thereby achieving the closing effect of the multiple groups of shovel plates 14 at the bottom, thereby shoveling and collecting the concrete debris generated by the drill bit 11, improving the automation efficiency of the sampling process of the device and reducing labor costs.
