[0001] The utility model belongs to the technical field of double-rotor hammer crushers, and in particular relates to a double-rotor hammer crusher with a multi-stage crushing structure. Background Art

[0002] The twin-rotor hammer crusher is a highly efficient crushing equipment, mainly used to crush materials of various hardness, such as calcite, limestone, coal cinder, slag, slag, shale, coal gangue, construction waste, etc.

[0003] The twin-rotor hammer crusher is driven by dual motors to make the two sets of rotors connected in series rotate at high speed at the same time. After the material is crushed by the upper rotor in the machine cavity, it is immediately crushed again by the hammer head of the rapidly rotating lower rotor, so that the twin-rotor hammer crusher has a multi-stage crushing structure inside, which makes the material crushing more uniform. However, when the twin-rotor hammer crusher is in use, since the feed port set on the top is open, the dust generated by the crushing will fly out from the feed port when the twin-rotor hammer crusher is crushing materials. This will easily make the air in the working environment contain more dust, causing the working environment to be polluted. At this time, when the staff works in such an environment, it is easy to bring harm to the health of the operators.

[0004] Therefore, the utility model provides a double-rotor hammer crusher with a multi-stage crushing structure to solve the above problems. Utility Model Content

[0033] Working principle: when using the double-rotor hammer crusher with a multi-stage crushing structure, the material to be crushed is put into the crusher mainframe 1 through the feed port 2, so that the material will first be hit and crushed by the hammer head of the upper rotor in the crusher mainframe 1, and then immediately crushed again by the hammer head of the rapidly rotating lower rotor, thereby realizing multi-stage crushing of the material and making the material crushed more evenly. When the material is crushed in the crusher mainframe 1, dust will fly outward from the feed port 2, which is also the reason for starting the dust suction fan 8, so that the input end of the dust suction fan 8 generates suction force through the connecting pipe 7 to the dust suction hood 6, so that there will be suction force at one end of the installation slot 5, and when the dust at the feed port 2 flies upward, the suction force at the installation slot 5 will transport the flying dust to the dust suction hood 6, so that the dust adsorbed in the dust suction hood 6 will be transported to the dust suction fan 6 through the connecting pipe 7. The dust collecting box 12 is transported by the machine 8, so that the output end of the dust suction fan 8 will transport the adsorbed dust through the conveying pipe 9 to the collection box 12 in the placement groove 11, so that the dust can be collected in the collection box 12 for subsequent centralized treatment. By operating in this way, the flying dust at the feed port 2 will not escape into the air of the working environment, ensuring that the working environment will not be polluted. Secondly, the protective net 17 is slidably placed in the slide groove 16, and then the bolt 18 is penetrated through the mounting plate 4 and screwed into the second fixing hole 19 to fix the position of the protective net 17 in the slide groove 16, so that the protective net 17 can be blocked at the open front end of the dust hood 6. In this way, when the crusher host 1 is performing feeding or crushing operations, part of the material splashing toward the dust hood 6 of the mounting slot 5 will be blocked by the protective net 17 to prevent the material from splashing into the dust hood 6 and causing the dust hood 6 to be blocked.
