Referring to fig. 1-3, a sampling tool according to an embodiment of the present invention includes a sampling rod 10 and a sampling spoon 20 fixed to the sampling rod 10.
In the present embodiment, a leakage pipe 30 is movably connected to the bottom plate 21 of the sampling spoon 20, wherein the leakage pipe 30 partially extends out of the bottom plate 21 downward relative to the sampling spoon 20; in the sampling spoon 20 of the present embodiment, a partition plate 22 is provided above a portion of the leak pipe 30 located in the sampling spoon 20, and an opening 221 is formed in the partition plate 22. That is, in the sampling spoon 20 of the present embodiment, the compartment 101 is formed by the upper bottom plate 21 and the partition plate 22, the portion of the leak pipe 30 disposed in the sampling spoon 20 is located in the compartment 101, and the leak pipe 30 can move relative to the compartment 101.
The leakage pipe 30 of the present embodiment is upwardly connected with the blocking block 40 through a connecting member, and the leakage pipe 30 can drive the blocking block 40 to selectively block the opening 221 through the connecting member. That is, when the leakage pipe 30 of the present embodiment moves downward, the blocking piece 40 is driven by the connecting member to block the opening 221 of the partition plate 22, and specifically, the blocking piece 40 can be driven by the gravity of the leakage pipe 30. That is, sampling scoop 20 of the present embodiment is capable of cooperating with partition 22 and forming a cavity 102 for holding material; when the leakage pipe 30 moves upwards, the blocking block 40 can be pushed through the connecting piece, so that the blocking block 40 releases the opening 221 on the partition plate 22, and the material contained in the cavity 102 can flow to the leakage pipe 30 through the opening 221 of the partition plate 22 under the action of gravity and is discharged outwards through the leakage pipe 30.
One end of the leakage pipe 30 facing the partition plate 22 is provided with a boss edge 31, the leakage pipe 30 can drive the boss edge 31 to abut against the partition plate 22 so as to limit the leakage pipe 30 to move towards the partition plate 22, and the blocking block 40 is driven by the connecting piece to block the opening 221 in the partition plate 22.
It can be understood that, in the present embodiment, the upper convex edge 31 of the leakage pipe 30 abuts against the partition plate 22, so as to increase the contact area between the leakage pipe 30 and the partition plate 22 when the leakage pipe moves upward, and further improve the stability of the partition plate 22 in limiting the leakage pipe 30 moving upward.
In this embodiment, the connecting member of this embodiment includes a mounting bracket 51 fixedly connected to the leakage pipe 30, and a connecting rod 52 disposed on the mounting bracket 51, the connecting rod 52 has a T-shaped connection joint 521 at an end far from the mounting bracket 51, a T-shaped groove 41 matched with the T-shaped connection joint 521 is formed on the blocking block 40, and the connecting rod 52 is connected to the blocking block 40 through the fit between the T-shaped connection joint 521 and the T-shaped groove 41, so that the blocking block 40 can move along with the up-and-down movement of the leakage pipe 30, and the purpose of controlling the flow of the material passing through the opening 221 of the partition plate 22 is achieved. Of course, it should be noted that the connection mode between the leak pipe 30 and the block 40 is not limited to the illustration, and it is obvious to those skilled in the art that the connection rod 52 can be directly connected and fixed with the block 40, or can be connected and fixed by using other connection joints.
The mounting bracket 51 of the present embodiment includes a plurality of connecting struts (not shown) fixed to the inner wall of the leakage pipe 30, the connecting struts intersect to form a mounting portion 511, and the connecting rod 52 is fixed to the mounting portion 511, so as to realize the assembling connection between the connecting rod 52 and the mounting bracket 51. The mounting bracket 51 of the present embodiment is composed of a plurality of connecting struts fixed to the inner wall of the leakage pipe 30, so that the mounting bracket 51 has a channel for material flow through, and ensures that the material passing through the opening 221 of the partition 22 can be discharged out through the leakage pipe 30.
In the present embodiment, the stopper 40 of the present embodiment is provided with the closing slope 42, the hole wall of the opening 221 in the partition plate 22 is set to the mating surface 222 that matches the closing slope 42, and the stopper 40 can close the opening 221 of the partition plate 22 by the abutment between the closing slope 42 and the mating surface 222. That is, the block 40 of the present embodiment can block the opening 221 of the partition plate 22 by the engagement between the two inclined surfaces. When the plugging block 40 is driven by the leakage pipe 30 to plug the opening 221 of the partition plate 22, the plugging block 40 can limit the leakage pipe 30 to move downwards continuously, so that the downward movement of the leakage pipe 30 is limited.
In this embodiment, the aperture of the opening of the leak pipe 30 facing the end of the stopper 40 is larger than the aperture of the opening 221, and the medium in the sampling spoon 20 can pass through the opening 221 and be discharged from the leak pipe 30. That is, the largest diameter of the bushing 30 of the present embodiment is larger than the diameter of the opening 221, so that the bushing 30 can receive the material passing through the opening 221.
The diameter of the leak pipe 30 of the present embodiment gradually decreases from the direction away from the partition 22, that is, the leak pipe 30 of the present embodiment is configured to be a funnel-shaped structure, so as to discharge the material contained in the sampling spoon 20 downward into the sampling bottle. It should be noted that the funnel-shaped funnel 30 allows the funnel 30 to be driven in a reverse direction by the sampling vial when the funnel 30 is in contact with the sampling vial, thereby facilitating the driving of the upward movement of the funnel 30.
In addition, it should be noted that the sampling rod 10 of the present embodiment is fixedly connected to the outer wall of the sampling spoon 20 along the axial direction of the sampling spoon 20, so that the sampling rod 10 drives the sampling spoon 20 to extend into the container and extract the material.
In summary, the sampling tool provided by the invention utilizes the reasonable structural arrangement of the leakage pipe, so that the leakage pipe can drive the blocking block to block the open hole on the partition plate under the action of gravity when the sampling tool is used for sampling, and the sampling spoon can contain materials; when the materials contained in the sampling spoon need to be discharged, the leakage pipe can be pushed upwards to drive the blocking block to remove the blocking of the opening on the partition plate, so that the materials contained in the sampling spoon can pass through the opening and are discharged outwards through the leakage pipe, the sampling operation of the sampling device is realized, and the sampling device has the advantages of convenience in operation and capability of avoiding the materials from splashing outwards; simultaneously, the sampling tool is simple in structure and convenient to operate, and further meets the use requirements of enterprises.
