DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1The utility model provides a technical solution: a vertical crusher includes a bottom bracket 1, which is composed of a bracket welded with a rectangular steel pipe and a large table top. A casing 2 is fixedly installed in the middle position above the bottom bracket 1, and the casing 2 is installed on the large table top by screws. A discharge port 3 is provided at the lower end of the casing 2, and a feed port 4 is provided at the upper end of the casing 2. A motor 5 with a rotating shaft facing upward is fixedly installed on one side of the casing 2, a lower bearing 6 is installed at the lower part of the casing 2, and an upper bearing 7 is installed at the upper part of the casing 2. A manual lubrication pump 18 is installed on the side above the bottom bracket 1 near the feed port 4, and an oil pipe 19 is provided between the manual lubrication pump 18 and the upper bearing 7 and the lower bearing 6. Through the manual lubrication pump 18 Lubricating oil can be pumped into the upper bearing 7 and the lower bearing 6 for lubrication. A connecting plate is welded at the lower part of the casing 2, and the lower bearing 6 is mounted on the connecting plate. A flat plate is arranged above the casing 2, and the feed port 4 and the upper bearing 7 are fixedly mounted on the flat plate by screws. A main shaft 8 is installed between the upper bearing 7 and the lower bearing 6. Pulleys 9 are installed on the main shaft 8 near the upper bearing 7 and the rotating shaft of the motor 5. A certain spacing gap is arranged between the pulley 9 and the inner wall of the feed port 4. The material is poured from the upper end of the feed port 4, and then the high-speed rotating pulley 9 can disperse the material to the surroundings. Finally, the material is evenly entered into the casing 2 from the gap. A V-belt 10 is arranged between the pulleys 9, and the main shaft 8 is near the upper A chain chuck 11 is arranged below the bearing 7, and a detachable pin shaft 12 is inserted around the chain chuck 11, and a disassembling chain 13 is installed between the pin shaft 12 and the chain chuck 11. The chain chuck 11 is fixed to the shoulder of the main shaft 8 by two locking nuts. An annular groove with a height slightly larger than the wire diameter of the disassembling chain 13 is arranged around the chain chuck 11. The disassembling chain 13 can be fixed to the chain chuck 11 by inserting one end of the disassembling chain 13 into the annular groove and then passing the pin shaft 12. Conversely, the disassembling chain 13 can be removed by removing the pin shaft 12. When the disassembling chain 13 rotates at a high speed, the falling materials can be dispersed. A rotor disk 14 is installed on the outer surface of the main shaft 8 between the chain chuck 11 and the lower bearing 6. A detachable turntable pin 15 is inserted around the periphery of the rotor disk 14, and a long blade 16 and a short blade 17 are installed between the turntable pin 15 and the rotor disk 14. The rotor disk 14 is fixedly connected to the main shaft 8 by welding. The rotor disk 14 is divided into three layers: upper, middle and lower. Three long blades 16 are installed on the upper layer and the lower layer through a turntable pin 15, and three short blades 17 are installed on the middle layer through a turntable pin 15. The blades between the same turntable pin 15 are provided with a spacer sleeve 20, and the spacer sleeve 20, the short blade 17 and the long blade 16 are all sleeved on the outer surface of the turntable pin 15. When the nine blades are stacked and rotated at high speed, they can repeatedly cut the falling materials to make the materials finer, and the crushed materials are discharged from the discharge port 3.

[0020] During use, the material is poured in from the feed port 4, and the material first contacts the top of the high-speed rotating pulley 9, and then the material is thrown to the periphery by the pulley 9, and then the material falls down from the gap between the pulley 9 and the feed port 4 into the inside of the casing 2, and the fallen material is first broken up by the high-speed rotating breaking chain 13, and then the broken up material explodes to the surroundings and fills the first layer of the rotor disk 14, and since the space on the first layer is relatively large, the material is broken up relatively open, and at this time, the material is initially cut back and forth by the three-layer long blades 16 on the first layer of the rotor disk 14 until the material is thrown to the edge and is reduced to a certain extent before it can fall down to the second layer of the rotor disk 14, and since the space on the second layer of the rotor disk 14 is narrow, the falling material becomes crowded, and at this time, the crowded material is more likely to collide with each other and splash back and forth, which increases the frequency of the material being cut by the three-layer short blades 17 on this layer, and then the material can be further broken up, and when the material is broken enough, it can fall to the rotor The third layer of the sub-disk 14, since the space of the third layer of the rotor disk 14 becomes larger, the materials that have been broken into pieces are broken up again. Most of the materials in this space have been broken up. If there are large particles that have not been broken up, they are not easily impacted by other materials at this time, and the large particles at this time will not suddenly accelerate downward due to mutual collision. Therefore, the few large particles that have not been chopped up can be completely chopped up by the three-layer long blades 16 on the third layer of the rotor disk 14, and then the materials can be evenly and completely chopped into pieces through the change of the size of the three-layer space and the back and forth cutting of the multi-layer blades. When the breaking chain 13 and the blade need to be replaced, it is only necessary to loosen the screws of the feed port 4 and the casing 2, and then pull out the turntable pin 15 and the pin shaft 12 upward from the top of the casing 2 to remove the blade and chain, which is very convenient. Similarly, it is also very convenient to put one end of the blade and chain into the corresponding position and insert the turntable pin 15 and the pin shaft 12 to complete the installation.

[0021] To sum up, the vertical crusher can install three groups of nine layers of blades on the periphery through the structural design of the rotor disk 14. The nine layers of blades can realize multiple cutting of the material to make the material more sparse. In the process of falling, the material is also broken up by the breaking chain 13 and the change of the size of the inner cavity of the long and short blades 17, so that the material is not only more evenly distributed in the process of being cut, but also splashes more actively, so that the material is cut more fully and more sparse. Since the chain is stuck on the periphery of the chain chuck 11 through the pin 12, the chain can be removed by pulling out the pin 12. Similarly, it is very convenient to fix the chain and the chain chuck 11 by inserting one end of the chain into the annular groove around the chain chuck 11 and inserting the pin 12. The blade is also connected to the rotor disk 14 through the turntable pin 15 in the same way. It is also very convenient to disassemble and assemble the blade and the rotor disk 14 by plugging and pulling out the turntable pin 15.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
