The utility model discloses an easily replaceable anti-wear device for a banana screen lower crossbeam, in which an easily replaceable wear-resistant protective top is arranged between the screen plate and the lower crossbeam, and under the protection of the wear-resistant protective top, the lower crossbeam is not worn. The easily replaceable banana screen lower crossbeam anti-wear device with the above structure has simple structure, easy replacement, better wear resistance, the life of the lower crossbeam is guaranteed, and can further improve the quality and service life of banana screen, and can achieve the effect that cannot be achieved by the existing method.
1. The utility model relates to an easily replaced banana screen lower crossbeam anti-wear device, which comprises a screen plate, a lower crossbeam, a screen plate fixing device, etc. The utility model is characterized in that the anti-wear device also comprises a wear-resistant top. The wear-resistant top is a column structure with an equal width sheet section, and the wear-resistant top is in the same direction and of the same length as the lower crossbeam. The wear-resistant top is sandwiched between the screen plate and the lower beam of the screen, and the wear-resistant top is pressed onto the lower beam of the screen plate while the screen plate is fixed by the screen plate fixing device. 2. An easily replaceable anti-wear device for the lower beam of a banana screen, wherein the wear-resistant top is made of stainless steel material.
3. The utility model relates to an easily replaceable anti-wear device for the lower beam of a banana screen, wherein the wear-resistant top is made of 3-10mm stainless steel plate
4. An easily replaceable anti-wear device for the lower beam of banana screen, wherein the wear-resistant top can be made of lighter and more wear-resistant alloy material.
5. The utility model relates to an easily replaceable banana screen lower crossbeam anti-wear device, wherein the wear-resistant top is made of a hard plastic material with relatively wear-resistant. 6. An easily replaceable anti-wear device for the lower beam of a banana screen, wherein the wear-resistant top can be made of a lighter and more wear-resistant carbon fiber material.
At present, the anti-wear methods and devices of the lower screen beam used in banana screen at home and abroad are conventional: ① spraying wear-resistant coating. This method is widely used at present, spraying wear-resistant materials mainly include polyamine grease, wear-resistant paint, porcelain imitation materials, etc. This method is relatively simple, but the wear-resistant layer is one-time, and after the wear-resistant layer is damaged, it can not be replaced on the site, affecting the overall service life of the lower beam of the screen. ② vulcanized wear-resistant rubber layer. This method is also widely used at present, but after the wear-resistant rubber layer is damaged, it can not be replaced at the use site, which also affects the overall service life of the lower beam of the screen. ③ Paste wear-resistant materials. "The beam device of banana screen box with wear-resistant layer", this method also has the problem that it is inconvenient to use on-site replacement and the replacement time is too long after the wear-resistant layer is damaged. ④ The sleeve can be easily replaced with a wear-resistant sleeve. "banana screen with anti-wear device", although this method solves the problem of simple replacement, but the structure is complex, the cost is high, and the use is not convenient.
