Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration sampling equipment, and particularly relates to an assembled sampler for geological exploration. Background Technique

[0002] Geological exploration can be generally understood as geological work. By using geological exploration methods such as surveying and mapping, geophysical prospecting, geochemical prospecting, drilling, adit exploration, sampling and testing, and geological remote sensing, the investigation and research work on geological conditions such as rocks, stratigraphic structures, minerals, groundwater, and landforms in a certain area is carried out. During the geological exploration process, a sampler is needed to sample rocks, stratigraphic structures, minerals, and groundwater to meet the work requirements of geological exploration. A good sampler can reduce the labor intensity of exploration personnel and bring a good working experience to users.

[0003] In the use of the assembled sampler on the market, a straight rod is mostly used to directly insert into the sampling port for sampling. It is difficult to collect some stones inside the sampler, and the user needs to repeat the operation many times. Moreover, the effective port is relatively wide, and it is difficult for the user to exert force to operate the assembled sampler for sampling, which brings troubles to the user. Therefore, we propose an assembled sampler for geological exploration. Content of the Utility Model

[0004] The purpose of the utility model is to provide an assembled sampler for geological exploration to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an assembled sampler for geological exploration, including a sampling bin, a main rod, and a bearing platform. The inner wall of the sampling bin is threadedly connected with an extension rod, and the upper end of the extension rod is threadedly connected with the main rod. The upper end of the main rod is welded with a welding head, and the upper end of the welding head is welded with a reinforcing rib. The outer wall of the main rod is sleeved with a bearing platform. The lower end of the sampling bin is fixed with a drill bit, and several sampling holes are opened inside the drill bit. Several partition plates are welded on the inner wall of the sampling bin, and a bracket is fixed on the side of the partition plate away from the sampling bin. Internal threads are provided on the inner wall of the bracket.

[0006] Preferably, the upper end of the reinforcing rib is welded with a handle, and several waist-tightening holes are opened in the middle of the handle, and the rod body passes through the waist-tightening holes.

[0007] Preferably, several side opening grooves are opened on the outer wall of the bearing platform, and the cross bar passes through the side opening grooves.

[0008] Preferably, several gaskets are fixed around the lower end of the bearing platform, and an upper cover body is fixed in the middle of the upper end of the bearing platform.

[0009] Preferably, a limiting ring is fixed to the upper end of the upper cover body, and a compression spring is fixed to the lower end of the bearing platform along the limiting ring. The bearing platform is elastically connected to the sampling bin through the compression spring.

[0010] Preferably, a docking groove is provided on the inner wall of the upper end of the extension rod, and an external thread docking head is fixed to the bottom of the lower end of the extension rod. The extension rod is threadedly connected to the internal thread at the bracket through the external thread docking head.

[0011] Preferably, the inner wall of the sampling bin is partitioned into several independent spaces by a partition board, and the independent spaces communicate with the sampling holes.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] When the assembled sampler for geological exploration is in use, the handle is used as the manual operation end, and several waist-tightening holes are provided in the middle thereof. A cross bar can be inserted along the waist-tightening holes to increase the holding range of the hand, which is convenient for exploration personnel to operate and improves the acquisition rate of soil sampling, bringing convenience to users.

[0014] The bearing platform serves as the load-bearing constraint component of the sampler. The bottom gasket of the bearing platform contacts the soil or rock on the surface of the sampling port, which satisfies the user's requirement to constrain and protect the sampler through the bearing platform. At the same time, the upper part of the sampling bin contacts the compression spring, and the sampling sample is exported from the sampling hole at the sampling bin through vibration and knocking force, which is convenient for the user to export some tightly squeezed sampling samples, bringing convenience to users.

[0015] The drill bit of the sampling bin adopts an elliptical design, which can well meet the sampling requirements of some soil and stones. At the same time, the sampling holes are partitioned into multiple independent spaces by partition boards, which satisfies the user's modular storage of multiple sampling samples, bringing convenience to users.

The upper end of the reinforcing rib 41 is welded with a handle 42, and a plurality of waist tightening holes 43 are opened in the middle of the handle 42, and the rod body passes through the waist tightening holes 43. The handle 42 is used as the manual operation end, and a plurality of waist tightening holes 43 are arranged in the middle of it. When the drilling operation is difficult, the user can insert a cross bar into the waist tightening holes 43 to increase the holding range of the hand, which is convenient for the exploration personnel to operate and use, and improves the acquisition rate of soil sampling, bringing convenience to the user. A plurality of side opening grooves 53 are opened on the outer wall of the bearing platform 5, and the cross bar passes through the side opening grooves 53. A plurality of gaskets 55 are fixed around the lower end of the bearing platform 5, and an upper cover body 51 is fixed in the middle of the upper end of the bearing platform 5.

[0023] Embodiment 2

[0024] Please refer to Figures 1 - 3, the present utility model provides a technical solution: an assembled sampler for geological exploration. The inner wall of the upper end of the extension rod 2 is provided with a docking groove 21, and the bottom of the lower end of the extension rod 2 is fixed with an external thread docking head 22.

[0025] Working principle: For this type of assembled sampler for geological exploration, first, the user places the bearing platform 5 on the sampling port, and the bottom gasket 55 of the bearing platform 5 contacts the soil or rock on the surface of the sampling port. When the sampling port is too large, the user can insert the cross bar through the side opening groove 53, and several cross bars fix and protect the bearing platform 5 to determine the depth of the sampling port. Then, the sampling bin 1, the extension rod 2 and the main rod 3 are threadedly connected.
