Description

Technical Field

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

[0002] Geological and mineral exploration is the foundational work for mineral resource development. It aims to use scientific methods to ascertain the geological conditions, mineral reserves, and mining technology conditions of a mining area, providing a reliable basis for mine construction design, production, and resource management. The exploration process involves geological surveying, geophysical exploration, geochemical exploration, drilling, and pitting. Ore sample crushing is a core aspect of geological and mineral exploration, directly affecting sample representativeness, analytical accuracy, and the reliability of resource evaluation.

[0003] Existing ore sample crushers are divided into: coarse crushing (jaw crushers and cone crushers); medium crushing (roll crushers and hammer crushers); and fine crushing (disc mills and vibratory mills). These devices generally have the following drawbacks: firstly, ferrous equipment can easily lead to higher iron content in ore samples, resulting in inaccurate subsequent measurements; secondly, uneven particle size, with over-crushing or under-crushing causing analytical errors, can lead to serious errors in subsequent analyses.

[0004] In conclusion, it is necessary to design a crushing device for ore samples in geological and mineral exploration to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that, in view of the problem that existing ore sample crushers are prone to causing high iron content in ore samples and uneven particle size, which leads to serious errors in subsequent analysis, a new ore sample crushing device for geological and mineral exploration is proposed.

The screen outlet is connected to the outside of the crusher body. Multiple feeding screen plates are installed on the bottom side wall of the screen cylinder. Each feeding screen plate is corresponding to a ceramic grinder. Multiple feeding ports are opened on the feeding screen plates and are connected to the ceramic grinder.

[0008] The screener can separate larger-sized ores, which are then sent out of the crusher body for further crushing and then sent back for grinding.

[0009] Furthermore, a vacuum cleaner is installed on the top of the screening cylinder, located on one side of the feed hopper.

[0010] Furthermore, the ceramic grinder includes a grinder shell, the top of which is an open structure and communicates with the screening cylinder. A horizontally arranged ceramic grinding sleeve is provided inside the grinder shell. The ceramic grinding sleeve is fitted onto the output shaft of the rotating motor. The rotating motor is fixed to the outer wall of the grinder shell. Multiple material leakage ports are opened on the bottom wall of the grinder shell and communicate with the guide cylinder.

[0011] In a preferred embodiment of this solution, the grading and screening rack includes multiple screening slots arranged sequentially from top to bottom. The multiple screening slots are fixedly connected by a bracket, and the bracket is connected to the output end of the vibration motor.

[0012] Furthermore, the bottom wall of the screening tank has a mesh structure, and the mesh aperture on the bottom wall of the screening tank decreases sequentially from top to bottom.

[0013] Furthermore, an openable door is provided on one side of the middle section of the crusher body.

[0023] Please see Figure 1 , Figure 1 A schematic diagram of the structure of the ore sample crushing device for geological and mineral exploration provided by this utility model. The ore sample crushing device for geological and mineral exploration includes: a crusher body 1.

[0024] The top of the crusher body 1 is equipped with a feed hopper 2 for feeding materials.

In this embodiment, the screener includes a screen cylinder 3, with a screw conveyor 4 fixedly installed at one end of the screen cylinder 3 and a screen outlet 5 installed at the other end, which is connected to the outside of the crusher body 1. Multiple feeding screen plates 6 are installed on the bottom side wall of the screen cylinder 3, and each feeding screen plate 6 corresponds to a ceramic grinder 7. Multiple feeding ports are opened on the feeding screen plates 6, and the feeding ports are connected to the inside of the ceramic grinder 7. The screw conveyor 4 pushes and conveys the ore entering from the feed hopper 2. Larger ore is output from the screen outlet 5, and smaller ore that meets the requirements falls into the ceramic grinder 7 for grinding from the feeding port.

[0026] In addition, a vacuum cleaner 8 is installed on the top of the screening cylinder 3, located on one side of the feed hopper 2. The vacuum cleaner can suck up dust when the ore sample enters and exits the screening cylinder.

[0027] The bottom of the filter is equipped with multiple interconnected ceramic grinders 7, please refer to [link / reference]. Figure 2-3 , Figure 2 A schematic diagram of the internal structure of a ceramic grinder; Figure 3This is a side view of the ceramic grinder. The ceramic grinder includes a grinder shell 9, the top of which is open and connected to the screening cylinder 3. A horizontally arranged ceramic grinding sleeve 10 is provided inside the grinder shell 9. The ceramic grinding sleeve 10 is fitted onto the output shaft of the rotating motor 11. The rotating motor 11 is fixed to the outer wall of the grinder shell 9. Multiple material leakage ports 12 are provided on the bottom wall of the grinder shell 9, and the material leakage ports 12 are connected to the guide cylinder 13.

[0028] A grading and screening frame 14 is provided in the middle of the crusher body 1. The grading and screening frame 14 is located below the guide cylinder 13 of the grinder outlet. A vibration motor 15 is fixedly installed at the bottom of the crusher body 1. The output end of the vibration motor 15 is connected to the grading and screening frame 14.

[0029] Specifically, please see Figure 4 , Figure 4 This is a schematic diagram of the grading and screening rack. The grading and screening rack 14 includes multiple screening tanks 16 arranged sequentially from top to bottom. The multiple screening tanks 16 are fixedly connected by a bracket 17, which is connected to the output end of the vibration motor 15. The bottom wall of the screening tank 16 has a mesh structure, and the mesh aperture on the bottom wall of the screening tank 16 decreases sequentially from top to bottom. Larger ore samples are screened in the upper screening tanks, while smaller ore samples fall into the lower screening tanks.

[0030] For easy access and maintenance, an openable door 18 is provided on one side of the middle of the crusher body 1.

[0031] In operation, the ore sample crushing device for geological mineral exploration involves feeding ore samples into the hopper. The ore falls into the screen, and under the propulsion of the screw conveyor, large-diameter ore particles are discharged from the crusher through the screening outlet. Ore particles of the appropriate size fall from the various discharge ports of the screening plate into the ceramic grinder, where they are ground by the ceramic grinding sleeve. After being ground, the ore falls from the guide cylinder into the grading screening rack, where it is vibrated by a vibrating motor. The grading screening rack then classifies and screens the ground ore particles. Ore particles of different sizes are screened into separate screening tanks and retrieved as needed.
