Description

Technical Field

[0001] This utility model belongs to the field of probability sieve technology, specifically relating to a swing-type probability sieve. Background Technology

[0002] A probability screen is a screening mechanism based on the principle of probability screening. It is designed based on the principle of material sliding relative to the screen surface and the polygonal effect of chain transmission. It adopts a multi-layer, large-angle screen structure and achieves rapid material classification through linear vibration, with a processing capacity 5 to 10 times greater than that of ordinary vibrating screens. Its core components include the screen box, vibrator, and support device, and it is characterized by its small size and resistance to screen clogging.

[0003] Most existing probability screens use vibrators for vibration screening, which can process multiple grades at once. However, when screening, the material is initially in a piled state, and the movement amplitude generated by vibration is small. Therefore, the utilization rate of the screen surface is low, which reduces the screening efficiency. At the same time, although most screen boxes are set up to facilitate discharge, when the material accumulates at the discharge port and gets stuck in the screen opening, it is difficult to completely remove it by the vibration of the vibrator alone. In order to solve the above problems, it is necessary to provide a swing-type probability screen with better performance. Utility Model Content

[0020] The lifting assembly 7 includes: a lifting hydraulic cylinder 701 disposed on the top of the main base 1, a spherical shell 702 connected to the top of the lifting hydraulic cylinder 701, an annular connecting groove seat 703 connected to the top of the spherical shell 702, and the inner wall of the annular connecting groove seat 703 being movably connected to a crossbar 207 disposed at the bottom of the housing 201.

[0021] The telescopic end of the lifting hydraulic cylinder 701 is connected to a connecting ball, and the outer wall of the connecting ball is movably connected to the inner wall of the spherical shell 702.

[0022] The auxiliary bracket assembly 8 includes: a connecting plate 802 connected to the top of the main base 1, a damper 803 connected to the outer wall of the connecting plate 802, a spring 801 connected to the outer wall of the connecting plate 802, and a slide seat 804 connected to the outer wall of the connecting plate 802; the top of the slide seat 804 is slidably connected to the inner wall of the pin 208.

The center of the arc-shaped groove is located on the axis of the output shaft of the motor 302, which allows the motor 302 to rotate the housing 201 to a greater extent.

[0024] It should be noted that most existing probability screens use vibrators for vibratory screening, which can achieve the effect of multiple grades in one process. However, when screening, the material is initially in a piled state, and the movement amplitude generated by vibration is small. Therefore, the utilization rate of the screen surface is low, which reduces the screening efficiency. At the same time, although most of them use inclined screening boxes for discharge, when the material accumulates at the discharge port and gets stuck in the screen opening, it is difficult to completely remove it by the vibration of the vibrator alone.

[0025] Specifically, in this embodiment, the solution mainly utilizes the main base 1, screen box assembly 2, side base 4, lifting assembly 7, auxiliary bracket assembly 8, side drive assembly 3, upper connecting rod 5, and lower connecting shaft 6. During use, the material to be screened is poured into the screen box, and vibration grading screening is initiated. Then, the lifting hydraulic cylinder 701 is activated and controlled, causing the screen box assembly 2 to rotate slightly along the connecting pin between the lower connecting shaft 6 and the vertical connecting column 303. The position of the screen box assembly 2 is slightly adjusted upwards, allowing the positioning block to insert into the positioning slot, completing the connection between the screen box assembly 2 and the motor 302. The motor 302 is then controlled to reciprocate within the movement range, causing the box 201 to not only vibrate and screen under the action of the vibrator 206 but also to shake and screen, improving the screening effect.

[0026] In this embodiment, the screen box assembly 2 includes key components such as a box body 201, multi-layer screen plates 209, and a vibrator 206. The inner diameter of the mesh openings in the multi-layer screen plates 209 decreases sequentially from top to bottom, achieving multi-level grading and screening of materials, ensuring efficient separation of materials of different particle sizes. The screen plates 209 are slidably connected to the limiting strips inside the box body 201 via rollers, facilitating quick installation, replacement, and maintenance, and reducing downtime. The vibrator 206 provides traditional vibrating screening, causing relative sliding of materials on the screen surface. However, when vibrating alone, materials tend to clump together, and the movement is limited. When used in conjunction with the side drive assembly 3, the oscillating motion driven by the motor 302 adds lateral swaying to the box body 201 on top of the vibration, allowing the material to be more evenly distributed on the screen surface, fully utilizing the screen area, avoiding local accumulation, and improving screening efficiency and throughput. In addition, the pin 208 and connecting crossbar 207 at the bottom of the box 201 are combined with the lifting assembly 7 and the auxiliary bracket assembly 8 to ensure stable swinging motion; the design of the discharge port 205 and the front door 203 facilitates material discharge and cleaning, further reducing the risk of material blockage.

[0027] In a further preferred embodiment of the present invention, the side drive assembly 3 includes a mounting base 301 connected to the top, a vertical connecting column 303 rotatably connected to the inner wall of the mounting base 301, a motor 302 connected to the top of the mounting base 301, the output shaft of the motor 302 being connected to the inner wall of the upper connecting rod 5 via a coupling, and an arc-shaped pad 304 connected to the outer wall of the mounting base 301. The arc-shaped pad 304 is set below the lower connecting shaft 6, and the arc-shaped pad 304 provides auxiliary support and limit the lower connecting shaft 6. The vertical connecting column 303 is a square vertical connecting column. The upper and lower ends of the vertical connecting column 303 are movably connected to the mounting base 301 by connecting pins, and the outer wall of the vertical connecting column 303 is rotatably connected to the inner wall of the lower connecting shaft 6 by a pivot pin.

[0028] In this embodiment, the side drive assembly 3 mainly includes a mounting base 301, a motor 302, a vertical connecting column 303, and an arc-shaped pad 304. The motor 302 drives the upper connecting rod 5 to reciprocate through its output shaft, thereby driving the screen box assembly 2 to perform a controllable swaying motion. This swaying motion, combined with the vibration of the vibrator 206, causes the material to generate multi-dimensional motion vibration and shaking on the screen surface, effectively breaking the initial piled state of the material, promoting the dispersion, stratification, and passage of the material through the screen, and improving screening efficiency and uniformity. The vertical connecting column 303 and the arc-shaped pad 304 provide stable support and limit, ensuring a smooth and reliable swaying process and avoiding excessive shaking or structural stress concentration. Through the adjustment of the lifting assembly 7, the positioning block of the upper connecting rod 5 can be inserted into the positioning slot in the connecting groove 204 of the screen box assembly 2, realizing a rigid connection between the two, so that the swaying motion is accurately transmitted to the box body 201. During discharge, the oscillating motion helps to shake off the material accumulated at the discharge port 205 and prevents the mesh from clogging, improving discharge efficiency and continuity. Furthermore, the damper 803 and spring 801 in the auxiliary bracket assembly 8 further buffer the impact of the motion, reducing equipment wear.

The specific models are not described here. The installation, connection, fixing, and use of the above components are all existing technologies and are not described in detail here.
