Description

Technical Field

[0001] This utility model relates to the field of soil sampling technology, and in particular to a sampling device for geological and mineral exploration. Background Technology

[0002] Sampling equipment for geological and mineral exploration is an indispensable key tool in the field of geological exploration, with wide applications in numerous areas such as geological research, mineral development, resource assessment, and environmental monitoring. In geological research, by obtaining samples of underground rocks and soil through sampling equipment, scientists can analyze information such as mineral composition, geological structure, and formation age, revealing the Earth's evolutionary history and geological laws. For mineral development, efficient sampling equipment can accurately collect ore body samples, helping prospectors determine important parameters such as mineral type, reserves, and grade, providing a scientific basis for the rational development and resource utilization of mines, resulting in significant economic benefits.

[0003] Current sampling equipment used in geological and mineral exploration has several areas for improvement. Taking a soil sampling device (CN217765579U) as an example, while it facilitates soil sample extraction to some extent, its collection cylinder, formed by two semi-circular cylinders open at both ends, presents problems in actual soil sampling operations. Because the lower ends of the two semi-circular cylinders lack effective restraint structures, they are prone to deformation or even cracking when sampling harder soil or under significant lateral pressure. This leads to device damage, shortens equipment lifespan, and increases exploration costs. In severe cases, it can delay the entire exploration project, causing considerable inconvenience and losses to geological and mineral exploration work.

[0004] In conclusion, designing a sampling device that can effectively prevent deformation of the lower end of the collection cylinder and enhance its structural stability and durability is an important issue that urgently needs to be addressed in the field of geological and mineral exploration.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1-2 This utility model provides a sampling device for geological and mineral exploration, including a force-applying rod 1, a support plate 2, an arc plate 3, a driving mechanism, and a sampling head 4.

[0032] The device comprises: a force-applying rod 1, which serves as the force-applying component; its upper end is vertically fixed to the middle of the operating rod 18; and anti-slip sleeves 19 are fixedly fitted on the outer surfaces of both ends of the operating rod 18 for easy gripping and pressure application by the operator. A support plate 2, fixedly connected to the lower end of the force-applying rod 1, is circular and has a diameter larger than that of the force-applying rod 1. Two arc-shaped plates 3 are present, their upper ends hinged to the two side edges of the support plate 2 via hinge shafts. The two arc-shaped plates 3 and the support plate 2 can be joined to form a downward-opening cylindrical structure. The two arc-shaped plates 3 are fitted with a clearance to achieve opening and closing. A drive mechanism is used to drive the lower ends of the two arc-shaped plates 3 to achieve the opening and closing state. A sampling head 4 is annular and detachably connected to the lower ends of the two arc-shaped plates 3.

[0033] Preferably, refer to Figure 2 and Figure 4 The sampling head 4 is annular, with an inner wall 5 and an outer wall 6 integrally formed on its upper part. The inner wall 5 and outer wall 6 are annular and are respectively located on the inner and outer sides of the lower end of the arc plate 3. The outer surface of the inner wall 5 is provided with a first external thread, and the lower end of the arc plate 3 is provided with an internal thread. The first external thread and the internal thread cooperate to achieve a detachable threaded connection between the inner wall 5 and the lower end of the arc plate 3. The outer wall 6 abuts against the lower end of the arc plate 3 to prevent the arc plate 3 from deforming or cracking inward or outward during sampling. To prevent the sampling head 4 from loosening when the force rod 1 is turned during sampling, a fastener 7 is connected through the inner wall 5, outer wall 6, and lower end of the arc plate 3. The fastener 7 is preferably a bolt and nut structure. The lower part of the sampling head 4 is provided with several blades 8 for cutting soil or mineral layers. The inner side wall is provided with multiple arc-shaped springs 9. One end of the spring is fixedly connected to the sampling head 4, and the other end extends along the direction close to the axis of the sampling head 4.

[0034] Reference Figure 1-3 The drive mechanism includes components such as a threaded sleeve 11, a sliding sleeve 12, and a connecting rod 15. A second external thread 10 is provided at the lower part of the force-applying rod 1, which is threadedly connected to the threaded sleeve 11. The threaded sleeve 11 is rotatably connected to the sliding sleeve 12 via a bearing 16. An operating ring 17 is provided on the threaded sleeve 11 for easy tightening by the operator. A first connecting lug 13 is fixedly connected to the outer wall of the sliding sleeve 12, and one end of the connecting rod 15 is hinged to the first connecting lug 13. A second connecting lug 14 is fixedly connected to the upper end of the arc plate 3, and the second connecting lug 14 is hinged to the other end of the connecting rod 15. The first connecting lug 13, the second connecting lug 14, the connecting rod 15, and the arc plate 3 are arranged in a one-to-one correspondence.

[0035] The method of use and operation steps of this utility model are as follows:

[0036] Equipment assembly and preparation: Tighten the operating ring 17 to move the sliding sleeve 12 downward along the force bar 1, so that the two arc plates 3 approach each other until they are combined with the support plate 2 to form a cylindrical structure. Connect the inner wall 5 of the sampling head 4 to the internal thread at the lower end of the arc plate 3, and further fix it with fasteners 7 to ensure a firm connection.

[0037] Sampling Operation: The operator holds both ends of the operating lever 18, using the anti-slip sleeve 19 to increase grip stability. The device is aligned with the geological location to be sampled, rotated, and downward pressure is applied simultaneously, causing the cylindrical structure composed of the arc plate 3 and the support plate 2 to insert into the soil or mineral layer. During insertion, the blades 8 of the sampling head 4 can cut through the soil or mineral, facilitating sampling. The spring 9 prevents the sample from loosening and falling out during sampling.

[0038] Sample collection and retrieval: After the arc plate 3 is fully inserted to the target depth, the force rod 1 is then lifted to pull out the entire sampling device. By unfastening the fastener 7, the sampling head 4 is unscrewed and removed from the lower end of the arc plate 3. Then, the operating ring 17 is rotated, causing the threaded sleeve 11 to rotate, which moves the sliding sleeve 12 upward along the force rod 1. The connecting rod 15 causes the upper end of the arc plate 3 to open to both sides, allowing the sample to be retrieved.

[0039] The beneficial effects of this utility model are as follows:

[0040] a. The design of the force bar 1 and the support plate 2 allows the equipment to be easily inserted into the soil or mineral layer. The blade teeth 8 and spring 9 structure of the sampling head 4 improve the sampling efficiency and sample integrity.

[0041] b. The design of the drive mechanism makes the opening and closing operation of the arc plate 3 simple. The sample can be collected and retrieved by rotating the operating ring 17, which improves the integrity of the sample.

[0042] c. In this invention, the upper part of the sampling head 4 is integrally formed with an inner wall 5 and an outer wall 6, which are annular in shape and respectively located on the inner and outer sides of the lower end of the arc plate 3. The outer surface of the inner wall 5 is provided with a first external thread, and the lower end of the arc plate 3 is provided with an internal thread. The inner wall 5 and the lower end of the arc plate 3 are detachably connected by threads, and the outer wall 6 abuts against the lower end of the arc plate 3. This design can effectively prevent the arc plate 3 from deforming and cracking inward or outward during the sampling process, thereby significantly improving the structural stability and durability of the device.
