Banana screen is mainly used in coal, mining, metallurgy and other industries, bearing the important functions of cleaning, grading, dehydration, desliming and desliming. In recent years, in order to adapt to the construction and development of china's high efficiency, energy saving, environmental protection of large coal preparation plants and mining plants, the banana screen of the material classification is gradually developed to a large scale, the market demand of large banana screen of thousands tons per hour is becoming more and more large. For large banana screen, the material on the screen plate of large banana screen on the market is difficult to quickly spread on the screen plate in time, and simply increasing the tilt angle of the screen plate will cause the material to slip out too fast through the discharge end and the screening effect will be reduced. In order to solve the above technical problems, we designed to provide a simple structure, and can quickly spread the material at the feed end, while ensuring adequate screening. A banana screen screen plate comprises a multi-segment screen plate, and the multi-segment screen plate is arranged sequentially and spliced in a slide-like manner along the front and back directions, the multi-segment screen plate and the horizontal plane tilt angle decreases from front to back, and the tilt angle between the subscreen plate and the horizontal plane at the front side does not exceed 40°. The inclined angle of the sub-sieve plate at the last side with the horizontal plane is not less than 3°. The beneficial effect of the technical solution is that by setting a multi-segment screen plate and splicing the multi-segment screen plate into a slidelike screen plate, that is, there is a certain angle between the adjacent two segments of the screen plate, so that the material at the feeding end of the screen plate can be quickly spread and at the same time, it can fully stay on each segment of the screen plate to realize the full screening of the material. The sieve plate is provided with 3-10 segments. The beneficial effect is that this makes the whole sieve plate more cushioned. The sub-screen plate in the technical scheme is provided with 6 segments, and the inclination angle between the sub-screen plate and the horizontal plane in the multi-segment is 27°, 23°, 19°, 15°, 11° and 7° successively. The beneficial effect of the technical solution is that the material can be quickly rolled out and screened, so that the material can be optimized between the residence time on the screen plate and the screening efficiency. In the scheme, the dimensions of the sub-sieve plates in the multiple sections are consistent. The beneficial effect of the scheme is that the sub-sieve plate can be manufactured in a unified specification, which makes the manufacturing cost lower and the preparation efficiency higher. In the scheme, a plurality of the sub-sieve plates are formed in one body. The beneficial effect of the scheme is that its structure is simple and the strength of the sieve plate is high. The second purpose is to provide a banana screen mesh box that can quickly spread the material at the feed end while ensuring adequate screening.
