Description

Technical Field

[0001] This utility model relates to the field of equipment technology for trench exploration engineering, specifically a sampling device based on trench exploration engineering. Background Technology

[0002] In the exploration and development of mineral resources, pit exploration is an important direct exploration method. It refers to the artificial exposure of ore bodies, geological structures and surrounding rocks by excavating tunnels (such as trenches, shallow wells, adits, rock gates, vein tunnels, and cross-vein tunnels) of a certain size and depth on the surface or underground, so that geologists can directly conduct geological observations, logging, sampling and obtain first-hand geological data.

[0003] Sampling of ore bodies revealed during pit exploration is a core component of mineral exploration and evaluation. The fundamental purpose of sampling is to obtain representative ore samples. However, current sampling work in pit exploration, especially trench sampling, mainly relies on manual operation of portable handheld samplers. This method has several drawbacks: 1. Operators must hold the sampling device throughout the entire sampling process, resulting in high labor intensity, time consumption, and significant effort; 2. The sampling process generates a large amount of dust, which operators are highly susceptible to inhalation during close-range work, posing a serious threat to their health; 3. For locations such as the tunnel roof, high sidewalls, or steep trench walls, manual access is difficult, often requiring the use of lifting platforms or scaffolding, which not only makes operation more inconvenient and time-consuming but also significantly increases the risk of falls from heights. Therefore, this application provides a sampling device based on pit exploration to solve the above problems. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a sampling device based on pit exploration engineering, including a base 1 with universal wheels at the bottom, guide rods 2 evenly distributed on the upper surface of the base 1, a lifting plate 5 slidably mounted on the guide rods 2, and a driving component for driving the lifting plate 5 to move up and down on the upper surface of the base 1. An adjustment plate 6 is rotatably mounted on the side of the lifting plate 5, and an electric push rod 7 is mounted on the side of the adjustment plate 6 away from the lifting plate 5. A sampler 71 is mounted on the telescopic end of the electric push rod 7 through a mounting base. The driving component drives the lifting plate 5 to move, and the lifting plate 5 drives the electric push rod 7 and the sampler 71 to a certain height through the adjustment plate 6. The operation of the electric push rod 7 and the sampler 71 is controlled. The electric push rod 7 pushes the sampler 71 to move and the sampling drill rod of the sampler 71 contacts the rock wall, and the sampler 71 begins sampling.

[0017] Furthermore, the driving component includes a main gear 4 rotatably mounted on the upper surface of the base 1 and a screw 3 rotatably mounted on the base 1. The screw 3 is threadedly connected to the screw hole in the middle of the lifting plate 5, and a secondary gear 31 is provided at the lower side of the screw 3. The main gear 4 and the secondary gear 31 are connected by a chain 41.

[0018] Furthermore, a handle is provided on the upper surface edge of the main gear 4. By rotating the main gear 4 through the handle, the main gear 4 drives the secondary gear 31 to rotate through the chain 41. The secondary gear 31 drives the screw 3 to rotate. During the rotation of the screw 3, the lifting plate 5 moves up or down along the guide rod 2. The lifting plate 5 drives the electric push rod 7 and the sampler 71 to move through the adjusting plate 6, thereby adjusting the initial position of the electric push rod 7 and the sampler 71.

[0019] Furthermore, the top of the screw 3 is provided with a top plate for rotation, and the top of the guide rod 2 is fixedly connected to the top plate, which can stabilize the screw 3 and the guide rod 2.

[0020] Furthermore, the adjusting plate 6 has evenly distributed positioning grooves 61 on one side edge corresponding to the lifting plate 5. The lifting plate 5 has an elastic column 8 in the middle of the end away from the adjusting plate 6. The telescopic end of the elastic column 8 is connected to the insertion rod 81 through the connecting plate. The insertion rod 81 moves through the lifting plate 5 and is engaged with the positioning groove 61. After holding the sampler 71, the elastic column 8 is pulled to disengage the insertion rod 81 from the positioning groove 61. Then, the adjusting plate 6 is rotated according to the sampling angle. The adjusting plate 6 drives the sampler 71 to rotate through the electric push rod 7. Finally, the elastic column 8 is released, and the elastic column 8 drives the insertion rod 81 to contact the adjusting plate 6. The angle of the adjusting plate 6 is finely adjusted so that the insertion rod 81 is inserted into the positioning groove 61, thereby locking and fixing the adjusting plate 6.

[0021] The electric push rod 7 and sampler 71 used in this utility model are common electrical devices in the prior art. Their working methods and circuit structures are well-known technologies and will not be described in detail here.

[0022] The sampler 71 is a portable handheld sampler in the prior art. In this application, the handle of the portable handheld sampler is removed, and then the portable handheld sampler is installed on the mounting base of the telescopic end of the electric push rod 7. The feeding action of the portable handheld sampler during sampling is controlled by the extension and retraction of the electric push rod 7.

[0023] When using:

[0024] Push the device to the appropriate position, hold the sampler 71 and pull the elastic column 8 to disengage the insertion rod 81 from the positioning groove 61. Then rotate the adjustment plate 6 according to the sampling angle. The adjustment plate 6 drives the sampler 71 to rotate through the electric push rod 7. Finally, release the elastic column 8. The elastic column 8 drives the insertion rod 81 to contact the adjustment plate 6. Fine adjust the angle of the adjustment plate 6 so that the insertion rod 81 is inserted into the positioning groove 61, thereby locking and fixing the adjustment plate 6.

[0025] By turning the main gear 4 with the handle, the main gear 4 drives the secondary gear 31 to rotate through the chain 41. The secondary gear 31 drives the screw 3 to rotate. During the rotation of the screw 3, the lifting plate 5 moves up or down along the guide rod 2. The lifting plate 5 drives the electric push rod 7 and the sampler 71 to move through the adjustment plate 6, thereby adjusting the initial position of the electric push rod 7 and the sampler 71.

[0026] The control is based on the operation of the electric push rod 7 and the sampler 71. The electric push rod 7 pushes the sampler 71 to move and the sampling drill rod of the sampler 71 contacts the rock wall, and the sampler 71 begins the sampling operation.

[0027] This utility model uses an adjustable electric push rod 7 to install the sampler 71, which can adjust the sampling angle of the sampler 71. It can take samples from the inner wall of the tunnel as needed, without the need for a platform, and can also prevent operators from inhaling dust. It has high operational safety, can greatly improve work efficiency, save manpower and time, and is simple to operate and convenient to use.
