Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for cone crushers, and particularly relates to a material distribution device for a crushing system. Background Art

[0002] In industries such as mining, construction, and metallurgy, cone crushers, as important crushing equipment, are widely used in the crushing process of various ores, rocks and other materials. However, in the actual production process, cone crushers often face some technical problems and challenges, which not only affect the normal operation of the equipment, but also increase the operating costs and economic losses of enterprises.

[0003] First of all, the feeding process of cone crushers often shows uneven feeding. Due to uneven feeding, the liners on the inner sidewalls of the crusher bear uneven impact forces, resulting in an accelerated wear rate of the sidewall liners and a significantly shortened replacement cycle. This not only increases the maintenance frequency of the equipment, but also affects the working efficiency and crushing effect of the crusher. Secondly, it is difficult to replace the feed inlet partition plate of the cone crusher. When the feed inlet partition plate is worn or damaged, it is necessary to stop the machine for replacement. However, due to the complexity of the equipment structure, the replacement process takes a long time, seriously affecting the normal production progress. In addition, due to the long maintenance time, it will also increase the production costs and manpower input of enterprises. Moreover, the feeding method of cone crushers usually presents a parabolic shape. This feeding method will cause uneven impact and wear of the materials in the crushing chamber, thus accelerating the periodic damage of the equipment. In the long run, this uneven feeding method will have a serious impact on the overall performance and stability of the equipment. Finally, during the eccentric feeding process of the cone crusher, due to the long feeding time, the main shaft of the lower frame of the crusher often shakes. This shaking not only poses a threat to the stability and safety of the equipment, but also causes serious problems such as cracking of the lower frame of the crusher. Once such a failure occurs, it will not only cause additional costs for equipment shutdown and maintenance, but also bring significant economic losses to enterprises. Summary of the Utility Model

[0004] In order to solve the problems existing in the prior art, the utility model provides a material distribution device for a crushing system, which solves the above technical problems.

[0005] To achieve the purpose of the utility model, the following technical solutions are adopted: A material distribution device for a crushing system includes a cylinder body and a flange. The cylinder body is hollow and has openings at both ends; a flange with the same inner diameter is welded to the lower end of the cylinder body; lifting lugs are respectively arranged at opposite positions on the outer wall of the upper end of the cylinder body; the flange is fixed on the liner by a plurality of bolts and nuts in cooperation.

[0006] Further, the inner diameter of the cylinder is 500 mm, the outer diameter is 520 mm, and the height is 500 mm.

[0007] Further, the inner diameter of the flange is 500 mm, the outer diameter is 560 mm, and the thickness is 20 mm.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] By adding this device at the upper end of the lining plate hole on the bracket and the lower end of the belt conveyor, on the one hand, it is convenient to vertically distribute the material blocks conveyed by the belt into the crusher, effectively avoiding damage to the eccentric shaft and main shaft of the cone crusher by the material. Thus, the service life of the crusher is increased, the replacement cycle is extended, and the labor cost is saved. And the flange welded at the lower end has the same inner diameter as the cylinder, ensuring the tightness and stability of the connection. In addition, the flange is fixedly corresponding to the lining plate hole through a plurality of bolts and nuts. This connection method is not only simple and reliable but also convenient for future disassembly and maintenance. The lifting lugs arranged on the outer wall of the upper end of the cylinder make the whole material distribution device more convenient during hoisting and transportation. Therefore, this material distribution device for the crushing system shows significant beneficial effects in terms of structural stability, installation convenience, working efficiency, adaptability, and equipment life.

[0016] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model:

[0017] Such as Figure 1-2As shown in the figure, a material distributing device for a crushing system includes a cylinder body 1 and a flange 2. The cylinder body 1 is hollow and has openings at both ends. A flange 2 with the same inner diameter is welded to the lower end of the cylinder body 1, firmly welding the flange 2 to the lower end of the cylinder body 1 to ensure there is no gap between the flange 2 and the cylinder body 1, and the plane of the flange 2 is perpendicular to the axis of the cylinder body 1. At opposite positions on the outer wall of the upper end of the cylinder body 1, there are respectively lifting lugs 3. The flange 2 is fixed to the lining plate through a plurality of bolts 4 and nuts 5. Holes matching the flange 2 are reserved on the lining plate of the crushing system. The combined body of the cylinder body 1 and the flange 2 of the material distributing device is placed at a predetermined position in the crushing system, and the flange 2 is fixed to the lining plate using a plurality of bolts 4 and nuts 5 to ensure that the flange 2 is closely attached to the lining plate without looseness.

[0018] Specifically, the inner diameter of the cylinder body 1 is 500 mm, the outer diameter is 520 mm, and the height is 500 mm.

[0019] Specifically, the inner diameter of the flange 2 is 500 mm, the outer diameter is 560 mm, and the thickness is 20 mm.

[0020] Specifically, the cylinder body 1 is made of steel material, which can effectively play a wear-resistant role and increase the service life of the equipment.

[0021] Specifically, there are two lifting lugs 3. Each lifting lug 3 is provided with a round hole, which is convenient for the crane to be buckled in the round hole to play a fixing role.

[0022] During use, construction workers lift it through the lifting lugs 3 on both sides of the cylinder body 1 and transport it to the lining plate 6 of the support 7 at the top of the crusher, vertically docking with the holes reserved on the lining plate 6. Then, the construction workers fix the entire material distributing device to the lining plate 6 through the cooperation of bolts 4 and nuts 5. Then turn on the belt conveyor. When the material falls from the belt conveyor to the crusher, it can fall vertically into the crusher interior, reducing the impact force of the material on the equipment.
