Description

Technical Field

[0001] The utility model belongs to the technical field of crushers, and in particular relates to a hammer crusher. Background Art

[0002] Hammer crusher mainly relies on impact energy to complete the material crushing operation. When the hammer crusher is working, the motor drives the rotor to rotate at high speed. After the material enters the crusher cavity, it is sheared and torn under the impact of the high-speed rotating hammer head until the material is broken. At the same time, the gravity of the material itself causes the material to rush from the high-speed rotating hammer head to the baffle and screen bars in the frame body. Materials larger than the screen hole size are retained on the screen plate and continue to be hit and ground by the hammer until they are crushed to the required output particle size and finally discharged from the machine through the screen plate.

[0003] However, when materials are poured into the hammer crusher, they are not poured evenly, which causes both the materials and the crushing mechanism to wait for the crushing process. For example, the materials cannot be fully crushed in the crushing chamber in the first time, and the crushing mechanism is partially idle. When the workload is large, materials of different sizes are mixed and piled up, which makes the waiting time for the crushing of small materials long. In addition, serious material accumulation makes it easy for the hammer crusher to get stuck and the processing mechanism to malfunction.

[0004] Therefore, a hammer crusher is needed to solve the problem in the prior art that both the material and the crushing mechanism have waiting time in the crushing process, which affects the crushing efficiency. Utility Model Content

[0024] This solution has the following working process: before use, the material to be crushed is added to the outer end of the horizontal screening frame 6 in the feed casing 3 from the feed port 4. The gradient gap 7 arranged on the horizontal screening frame 6 allows the material to fall into the crushing studio of the hammer crusher body 1 according to size. This can prevent the mixing of materials of different sizes, resulting in the problem of small materials having to wait for a long time for crushing. The differentiated processing of material sizes can improve the efficiency of the overall crushing process by improving the crushing efficiency of small materials.

[0025] According to the above working process, it can be known that the gradual gap 7 set on the horizontal screening frame 6 allows the materials to fall into the crushing studio of the hammer crusher body 1 according to their sizes, which can prevent the mixing of materials of different sizes and the problem of small materials having to wait for a long time for crushing.

After the material is accumulated on the horizontal screening frame 6, the electric telescopic rod 11 is turned on, and the output end of the electric telescopic rod 11 drives the material-shifting plate 8 to scrape along the horizontal screening frame 6, so that the accumulated material can be pushed along the gradual gap 7 of the horizontal screening frame 6 to promote the classification and falling of the material according to the size. In addition, the overall degree of material falling can be improved during the material pushing process, thereby improving the condition of the crushing mechanism being locally used for crushing processing.
