Description

Technical Field

[0001] This utility model relates to the field of grading and screening, specifically a grading and screening device for geological and mineral resources. Background Technology

[0002] The process of separating loose materials into different particle sizes through a sieve is called ore screening. In mineral processing plants, screening is often combined with crushing operations. When ore is classified by the particle size of the product using screening equipment, unqualified oversized mineral particles are returned to the crushing operation for further crushing. This type of screening is called inspection screening. Geological and mineral grading and screening devices are used to classify and screen collected geological ores. Their main function is to separate raw materials into different grades according to different particle sizes and densities for subsequent processing and utilization.

[0003] However, since the outer diameter of various materials in mineral deposits varies, directly using slope screening can easily lead to poor material screening accuracy. Utility Model Content

[0007] As a further improvement of this utility model: the first screening box, the second screening box, and the third screening box are provided with material discharge notches at the ends away from and near the inclined guide frame.

[0008] As a further embodiment of this utility model: the mounting frame is fixedly connected to the conveyor belt, and the scraper is fixedly connected to the mounting frame.

[0009] As a further improvement of this utility model, a meshing gear is installed on the outer end of the rotating rod corresponding to the inner side of the conveyor belt.

[0020] 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.

[0021] like Figures 1-5As shown, this embodiment provides a grading and screening device for geological minerals, including a screening mechanism 1. The screening mechanism 1 includes a first screening box 2, a second screening box 3, and a third screening box 4. Each of the first screening box 2, second screening box 3, and third screening box 4 has a screen 8 installed inside. The aperture of the screen 8 inside the first screening box 2, second screening box 3, and third screening box 4 decreases progressively. A scraping mechanism 7 is installed on the upper surface of each of the first screening box 2, second screening box 3, and third screening box 4. The scraping mechanism 7 includes... Includes: a rotating rod 701, a rotating ear plate 706, a conveyor belt 702 meshing with the outer side of the rotating rod 701, a meshing gear corresponding to the inner side of the conveyor belt 702 at the outer end of the rotating rod 701, a mounting frame 704 mounted on the upper surface of the conveyor belt 702, the mounting frame 704 being fixedly connected to the conveyor belt 702, a scraper 705 array mounted on the upper surface of the mounting frame 704, the scraper 705 being fixedly connected to the mounting frame 704, and a drive motor 703 connected to one end of the rotating rod 701 via a drive belt.

[0022] like Figures 2-3 As shown, in this embodiment, inclined guide frames 6 are installed on the outer ends of the first screening box 2, the second screening box 3, and the third screening box 4. A collection bin 5 is provided below the third screening box 4. A material discharge notch 201 is provided at the end of the first screening box 2, the second screening box 3, and the third screening box 4 that is away from and close to the inclined guide frame 6. The inclined guide frame 6 is fixedly connected to the first screening box 2, the second screening box 3, and the third screening box 4.

[0023] The working principle of this utility model is as follows: The screen mesh 8 inside the first screening box 2, the second screening box 3, and the third screening box 4 has decreasing hole sizes. Therefore, when the ore raw material is placed above the screening mechanism 1, the scraping mechanism 7 located above the first screening box 2 is controlled to work. The drive motor 703 drives the rotating rod 701 to rotate via a belt. The gear on the outside of the rotating rod 701 meshes with the conveyor belt 702 to complete the transmission of the conveyor belt 702. The mounting frame 704 installed above the conveyor belt 702 is moved as a whole. When the mounting frame 704 is pulled above the first screening box 2, When the mounting frame 704 is moved to the lower position, the scraper 705 above the mounting frame 704 will move the ore accumulated above the first screening box 2. The ore with a diameter larger than the mesh size of the screen 8 inside the first screening box 2 will be pushed away from the discharge gap 201 located outside the first screening box 2 and transported away through the inclined guide frame 6. The ore with a diameter smaller than the mesh size of the screen 8 inside the first screening box 2 will fall into the second screening box 3. Then, the scraping mechanism 7 located on the second screening box 3 and the third screening box 4 will be activated in sequence to push and transport the ore of different diameters in sequence. Finally, the ore powder smaller than the inside of the third screening box 4 will be collected into the inside of the collection bin 5.
