In the first embodiment, as shown in fig. 1, a slurry sampling tool comprises a pull rope structure and a sampling barrel 1 with an opening in the middle of the upper end surface;

as shown in fig. 2-5, the sampling barrel 1 is internally provided with a valve plate 2 with a diameter smaller than the inner diameter of the sampling barrel and capable of blocking the opening when being lifted upwards, the middle part of the upper plate surface of the valve plate 2 is provided with a lifting lug 3 for lifting the sampling barrel upwards, and the lifting lug 3 is correspondingly connected with a pull rope structure so as to facilitate the lifting of the valve plate 2 upwards.

According to the need, as shown in fig. 2-3, the top surface of the sampling barrel 1 may be a flat plate with an opening in the middle, and the valve plate 2 may be a flat plate; as shown in fig. 4-5, the valve plate 2 may be a conical plate or cone or a truncated cone, and the conical upper end is cut into an opening, so that the sampling barrel 1 is opened into a conical hole.

Further, for convenience of staff carrying the sampling barrel 1, the top of the sampling barrel 1 is provided with two symmetrically arranged handles 11.

The setting can be under the effect of gravity through stay cord structure to sample bucket 1 descends to mud bottom to in this process, stay cord structure has ascending tractive force to lug 3, consequently valve plate 2 can block up sample bucket 1 opening, prevents that mud from getting into in the sample bucket 1; when the sampling bucket 1 descends to the bottom of mud, the sampling bucket 1 does not descend any more at this moment, then the valve plate 2 continues to descend under the action of gravity, and bottom mud enters the sampling bucket 1 through the opening of the sampling bucket 1 at this moment, when the sampling bucket is lifted through the pull rope structure, the valve plate 2 ascends at first until the valve plate 2 plugs the opening of the sampling bucket 1, and then the sampling bucket 1 is driven to ascend, so that the ascending in-process valve plate 2 can plug the opening of the sampling bucket 1.

The lower end of the sampling bucket 1 is of a closed structure, so that even if particles exist between the valve plate 2 and the opening of the sampling bucket 1, the leakage of slurry in the sampling bucket 1 is avoided, and the technical problem that in the prior art, when the particles exist in liquid, the liquid in the shell is easily leaked due to the particles, so that the device cannot be suitable for the sampling work of slurry after pile foundation drilling is solved.

As shown in fig. 1, the pull rope structure comprises a mounting frame 4, a winding drum 5 which is horizontally arranged is rotatably connected to the top of the mounting frame 4, a handle 6 is arranged at one end of the winding drum 5, a pull rope 7 is wound on the drum body of the winding drum 5, and a lifting hook 8 which can be correspondingly hung with a lifting lug 3 is arranged at the outer end of the pull rope 7;

the handle 6 can be rotated to enable the winding drum 5 to rotate, the pull rope 7 is firstly unreeled or wound, and then the function of lowering or lifting the sampling barrel 1 is achieved.

Further, as shown in fig. 1, in order to prevent the sampling bucket 1 from swaying left and right due to the change of the position of the pull rope 7 extending from the spool 5, two wire wheels 9 with rope grooves are disposed at the position of the mounting frame 4 corresponding to the lower part of the middle part of the spool 5, and the rope grooves in the two wire wheels 9 form a wire hole for the pull rope 7 to penetrate.

The setting can restrict stay cord 7 through two mutually supporting reel 9 like this, prevents that stay cord 7 from being located the position of reel 9 below and controlling the swing, and then can prevent that sampling bucket 1 from controlling the swing, has guaranteed the stability that sampling bucket 1 goes up and down.

Further, as shown in fig. 1, the mounting frame 5 includes a square frame 41, two herringbone plates 42 are disposed at two ends of the top surface of the square frame 41, the two herringbone plates 42 are disposed opposite to each other, and a winding drum 5 is rotatably connected between the tops of the two herringbone plates 42.

The herringbone plate 42 can enable the upper end of the mounting frame 5 to be smaller, and the overall weight can be effectively reduced.

Further, as shown in fig. 1, the two longitudinal ends of the square frame 51 are provided with axial insertion holes 411. When the size of the mounting frame 5 is smaller than the size of the pile foundation drilling hole, the length of the square frame 51 can be increased by inserting other rods into the insertion holes 411, so that the position of the square frame 51 is fixed; that is, the volume of the mounting frame 5 is further reduced, and the carrying is facilitated.
