Description

Technical Field

[0001] The invention relates to the technical field of material crushing, and in particular to a crushing device with a screening structure. Background Art

[0002] With the acceleration of industrialization, crushing equipment has been widely used in mining, building materials, recycling and other fields. However, the existing crushing equipment still has a series of shortcomings in actual work, which restricts its efficiency and applicability. Many traditional crushing equipment often have low crushing efficiency when processing large pieces of materials. This is because the crushing principle and structural design of the equipment limit its processing capacity and it is difficult to meet the needs of efficient production. For example, when facing hard materials, common jaw crushers often need to crush them multiple times to achieve the required particle size, which not only takes time but also reduces the overall work efficiency. Existing crushing equipment usually consumes high electrical energy during the working process, especially in large-scale production, the energy consumption problem is particularly prominent. The increase in energy consumption not only increases operating costs, but also burdens the environment. When many equipment are running for a long time, the motor power is inefficient, resulting in energy waste. In traditional crushing equipment, the material crushing method is limited, resulting in uneven particle size distribution of the output material. This uneven distribution may affect subsequent screening and processing procedures, resulting in a waste of resources.

[0003] During the use of crushing equipment, since the materials are irregular in size and model, they need to be crushed and screened. Otherwise, the large and small materials after crushing are mixed together and need to be separated again for later use, which not only wastes time but also reduces efficiency. In addition, the crushed materials may get stuck at the screening holes, and the stuck materials need to be automatically processed, otherwise the smaller screening holes will be blocked, affecting the screening of the materials. Summary of the invention

[0017] When the crushing equipment of the present invention is in use, the two crushing rollers rotate in opposite directions and the crushing teeth will squeeze and crush materials of different sizes. When the crushed materials pass through the screening holes, they will be screened in turn by the screening holes of different sizes.

[0019] In addition, the material on the guide plate will roll to the right for transportation. At this time, the material is blocked and restricted by the two protective plates, and the material will not fall from the front and rear ends of the guide plate. In this way, the broken material can be stably transported from the guide plate.

[0020] All the screening holes are arranged from left to right and from small to large. The size of the material will fall according to the size of the screening holes and fall into the corresponding screening box below, while the larger material will continue to roll to the right from the screening frame, and the larger material will roll down from the right end of the screening frame. When the material rolls to the right and hits the limiting plate, the limiting plate will flip to the right and fall into the material box below to prevent the larger material from rolling down from the right end of the screening frame and accidentally injuring the surrounding personnel. In this way, all the broken materials will enter the corresponding screening box, and all the broken materials can be effectively distinguished, which is convenient for the staff to directly use materials of different types in the later stage, thereby improving efficiency.
