AI Technical Summary
The drill barrel and drill rod of the existing powder material sampling machine wear out severely during use, resulting in frequent replacements, increased spare parts costs and reduced equipment life.
The drill barrel adopts a welded structure consisting of the drill barrel body and the drill barrel head ring. When wear reaches a certain level, the damaged parts are repaired by cutting and welding, thus extending the service life of the drill barrel.
This extends the lifespan of the sampler, reduces the frequency of replacement and spare parts costs, and improves the stability and durability of the equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling component technology, and in particular to a sampling end structure with a lifespan extension effect. Background Technology
[0002] The sampling rod mechanism of the powder material sampler is made of stainless steel with 8000 operating points. When the sampler drills downwards, the drill bit and the front of the outer cylinder come into contact with the material first, resulting in greater stress and more severe wear. The friction between the rotating sampler and the material causes gradual wear on the drill cylinder and drill rod. However, the drill rod is an active device and is made of thicker material, so the wear on the drill cylinder is more severe than that on the drill rod. When the drill cylinder becomes thinner and the gaps become larger, the sampling sway increases. The drill rod will rub against the drill cylinder due to centrifugal force, leading to increased wear on the drill cylinder head, increased sway, resonance, and abnormal noise. This can reduce the performance of other mechanisms and electrical components of the sampler. When the friction becomes too thin, it can even tear the drill cylinder. Therefore, the drill cylinder must be replaced promptly around 8000 points.
[0003] In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been well resolved: the wear of the drill pipe has not yet reached the replacement standard, resulting in poor integration of the old and new parts, and replacing the drill pipe at the same time will indirectly increase the cost of spare parts. Utility Model Content
[0004] The main purpose of this invention is to provide a sampling end structure with extended lifespan, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A sampling end structure with extended lifespan includes a drill barrel body, a drill barrel head ring at the bottom of the drill barrel body, a welded seam between the drill barrel body and the drill barrel head ring, and a drill bit at the bottom of the drill barrel head ring.
[0007] Preferably, the side of the drill barrel body closest to the drill barrel head ring is a plane.
[0008] Preferably, one side of the drill barrel body is a flat surface, which is welded to the head ring of the drill barrel.
[0009] Preferably, the drill barrel body and the drill barrel head ring are in contact on the side that are close to each other.
[0010] Preferably, the drill barrel body and the drill barrel head ring are welded together at the weld seam.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] When approximately 5000 samples have been taken, the damaged and worn parts of the existing drill barrel body are removed, and the cut area is the location of the weld seam. Then, the middle section of a scrapped drill barrel of the same material is proportionally cut to create a sampling drill barrel head ring. Welding is then performed at the weld seam between the drill barrel body and the drill barrel head ring. This restores the function of the front part of the sampling drill barrel, repairs the damage, restores the function of the drill bit, and achieves the following effect:
[0013] No need for frequent replacements, greatly reducing costs;
[0014] The same material was used for implementation, effectively restoring the function of the sampler drill rod;
[0015] Implemented within reasonable damage limits, this method effectively strengthens easily worn parts of the drill barrel, reduces resonance in the entire sampling mechanism, and extends the service life of electrical components and the sampling rod mechanism.
[0016] During use, the number of sampling points was effectively increased from 8,000 to 15,000, thus extending the service life. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] like Figure 1-2 As shown, the sampling end structure with extended service life includes a drill barrel body 1, a drill barrel head ring 2 at the bottom of the drill barrel body 1, a welded seam 4 between the drill barrel body 1 and the drill barrel head ring 2, and a drill bit 3 at the bottom of the drill barrel head ring 2.
[0022] Specifically, the side of the drill barrel body 1 closest to the drill barrel head ring 2 is a flat surface, and the side of the drill barrel head ring 2 that is welded to the drill barrel body 1 is also a flat surface. The sides of the drill barrel body 1 and the drill barrel head ring 2 that are close to each other are in contact. The drill barrel body 1 and the drill barrel head ring 2 are welded together at the weld seam 4. This ensures that the drill barrel body 1 and the drill barrel head ring 2 maintain good fit when they are to be welded at the weld seam 4, avoiding the problem of increased welding difficulty and reduced stability after welding due to uneven contact of the cutting surfaces.
[0023] Working principle: When sampling is performed at approximately 5000 points, the damaged and worn parts of the existing drill barrel body 1 are cut off. The cut point is the location of the weld seam 4. Then, the middle part of the scrapped drill barrel of the same material is proportionally cut to make the sampling drill barrel head ring 2. Welding is then performed at the weld seam 4 between the drill barrel body 1 and the drill barrel head ring 2 to restore the function of the front part of the sampling drill barrel, repair the damage, and restore the function of the drill bit 3.
[0024] When cutting damaged or worn parts of the drill barrel body 1, as well as cutting old drill barrels, the cut surfaces must be kept flat so that the drill barrel body 1 and the drill barrel head ring 2 can maintain good fit when they are about to be welded at the weld seam 4. This avoids the problem of increased welding difficulty and reduced stability after welding due to uneven contact of the cut surfaces.
[0025] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
