[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figures 1 - 4As shown in the figure, the roller mill includes a lower housing 2. One side of the lower housing 2 is fixedly connected with a motor 3. The output end of the motor 3 is cooperatively connected with a transmission shaft 4. A spiral impeller 7 is fixedly sleeved on the transmission shaft 4. An upper housing 1 is cooperatively arranged on the lower housing 2. After the lower housing 2 and the upper housing 1 are spliced, a sealed ore crushing space can be formed. A feed pipe is arranged on the upper housing 1, and a discharge pipe is arranged at the bottom of the lower housing 2. The device further includes a strengthening mechanism 5 and a mounting plate 8. The strengthening mechanism 5 includes an upper strengthening body 501 and a lower strengthening body 503 that cooperate with each other. Multiple groups of upper strengthening bodies 501 are arranged and fixedly connected to the upper housing 1. Multiple groups of lower strengthening bodies 503 are arranged and fixedly connected to the lower housing 2. Connecting bolts 504 are cooperatively arranged on both sides of each group of upper strengthening bodies 501 and lower strengthening bodies 503. The connecting bolts 504 are responsible for maintaining the relative positions of the lower strengthening body 503 and the upper strengthening body 501, and thus maintaining the relative positions of the lower housing 2 and the upper housing 1. Two groups of mounting plates 8 are arranged. The two groups of mounting plates 8 are respectively sleeved on the transmission shaft 4 at both ends of the spiral impeller 7. Multiple groups of equally spaced auxiliary shafts 9 are arranged between the two groups of mounting plates 8. Multiple groups of equally spaced crushing wheels 10 are cooperatively arranged on each group of auxiliary shafts 9. A first disassembly and assembly component is cooperatively connected between the auxiliary shaft 9 and the crushing wheel 10. The first disassembly and assembly component is responsible for maintaining the relative positions of the crushing wheel 10 and the auxiliary shaft 9. A second disassembly and assembly component is arranged between both sides of each group of auxiliary shafts 9 and the mounting plate 8. The second disassembly and assembly component is responsible for maintaining the relative positions of the auxiliary shaft 9 and the mounting plate 8. When maintenance is required inside the lower housing 2 and the upper housing 1, the connecting bolts 504 on the upper strengthening body 501 and the lower strengthening body 503 can be removed, thereby unlocking the upper strengthening body 501 and the lower strengthening body 503, facilitating the separation of the lower housing 2 and the upper housing 1, and completing the maintenance of the components inside the lower housing 2 and the upper housing 1. By operating the second disassembly and assembly component, the auxiliary shaft 9 and the mounting plate 8 are separated from each other, facilitating the maintenance and replacement of the auxiliary shaft 9. By operating the first disassembly and assembly component, the crushing wheel 10 and the auxiliary shaft 9 are separated, facilitating the maintenance and replacement of the crushing wheel 10. During use, crushing wheels 10 of different sizes can also be installed according to needs to control the crushing degree of the ore.

[0024] In some specific implementation schemes, in order to realize the hoisting of the upper strengthening body 501 and the upper housing 1, a hoisting hole 502 is provided on each group of upper strengthening bodies 501. When the connecting bolts 504 arranged on the upper strengthening body 501 and the lower strengthening body 503 are removed, a hoisting tool can be passed through the hoisting hole 502 to perform an upward pulling operation on the upper strengthening body 501, thereby driving the upper strengthening body 501 and the upper housing 1 to move upward, exposing the crushing components located between the lower housing 2 and the upper housing 1, facilitating the maintenance of the crushing components.

[0025] In some specific embodiments, in order to position the secondary shaft 9, each group of second disassembly and assembly components includes multiple groups of mounting posts 12 fixedly connected to the mounting plate 8. A mounting sleeve 13 that cooperates with the secondary shaft 9 is sleeved on the mounting post 12. Both ends of the secondary shaft 9 are butted against the corresponding mounting posts 12, and the mounting sleeve 13 is pushed to be sleeved between the secondary shaft 9 and the mounting post 12, thereby realizing the positioning of the secondary shaft 9.

[0026] In some specific embodiments, in order to maintain the position of the mounting sleeve 13, multiple groups of equally spaced limiting holes 11 are provided on each secondary shaft 9. A fixing bolt 14 that cooperates with the limiting holes 11 is threadedly connected to the mounting sleeve 13. When the mounting sleeve 13 is sleeved on both ends of the secondary shaft 9 to limit the secondary shaft 9, the fixing bolt 14 on the mounting sleeve 13 can be rotated to insert the fixing bolt 14 into the limiting holes 11 on the side of the secondary shaft 9, thereby realizing the positioning between the secondary shaft 9 and the mounting sleeve 13. The mounting sleeve 13 is sleeved on the mounting post 12 on the mounting plate 8, thereby realizing the positioning between the secondary shaft 9 and the mounting plate 8. The installation method of the secondary shaft 9 is similar to the disassembly method of the secondary shaft 9.

[0027] In some specific embodiments, in order to disassemble the crushing wheel 10, the first disassembly and assembly component includes connecting plates 1002 arranged on both sides of the crushing wheel 10. A locking bolt 6 that cooperates with the limiting holes 11 is threadedly connected to the connecting plates 1002. The connecting plates 1002 are locked with the limiting holes 11 at the corresponding positions through the locking bolt 6, thereby realizing the positioning of the crushing wheel 10. When the crushing wheel 10 needs to be replaced, the corresponding secondary shaft 9 needs to be disassembled from the mounting plate 8, and then the locking bolts 6 located on both sides of the crushing wheel 10 are removed, so that the crushing wheel 10 can slide along the secondary shaft 9, facilitating the pushing of the crushing wheel 10 to disengage from one end of the secondary shaft 9, completing the separation between the secondary shaft 9 and the crushing wheel 10. The installation method is similar to the disassembly method.

[0028] In some specific embodiments, in order to improve the crushing effect, each group of crushing wheels 10 includes an inner wheel 1001, and an outer wheel 1003 is arranged on the outside of the inner wheel 1001 in a cooperative manner. The outer wheel 1003 can rotate coaxially along the inner wheel 1001 under the action of an external force. The connecting plates 1002 are fixedly connected to both sides of the inner wheel 1001. When the motor 3 drives the crushing wheel 10 to rotate, the crushing wheel 10 continuously impacts and squeezes the ore with the outer wheel 1003. At this time, the outer wheel 1003 rotates under the action of the external force, so that the ore debris can be conveyed between the outer wheel 1003 and the housing under the action of the edge of the outer wheel 1003 for extrusion, making the ore debris crushed more thoroughly instead of being directly knocked away, breaking the ore by the impact force, and at the same time reducing the wear of the ore on the surface of the outer wheel 1003 and improving the service life of the crushing wheel 10.

[0029] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of the embodiments of this solution will be described below in combination with specific application scenarios:

[0030] When maintenance is required for the interior of the lower housing 2 and the upper housing 1, the connecting bolts 504 on the upper reinforcing body 501 and the lower reinforcing body 503 can be removed, thereby releasing the locking between the upper reinforcing body 501 and the lower reinforcing body 503, so as to facilitate the separation of the lower housing 2 and the upper housing 1 and complete the maintenance of the components inside the lower housing 2 and the upper housing 1. When it is necessary to separate the mounting sleeve 13 and the auxiliary shaft 9, the fixing bolt 14 on the mounting sleeve 13 can be rotated, so that the fixing bolt 14 slides out of the limiting hole 11 on the side of the auxiliary shaft 9, and the mounting sleeve 13 is pushed to leave the side of the auxiliary shaft 9, so that the auxiliary shaft 9 and the mounting plate 8 are separated from each other, facilitating the maintenance and replacement of the auxiliary shaft 9. When it is necessary to replace the crushing wheel 10, the corresponding auxiliary shaft 9 needs to be removed from the mounting plate 8, and then the locking bolts 6 located on both sides of the crushing wheel 10 are removed, so that the crushing wheel 10 can slide along the auxiliary shaft 9, facilitating the pushing of the crushing wheel 10 to disengage from one end of the auxiliary shaft 9, completing the separation of the auxiliary shaft 9 and the crushing wheel 10, and thus facilitating the maintenance and replacement of the crushing wheel 10. Different-sized crushing wheels 10 can also be installed according to needs during use, so as to control the crushing degree of the ore;

[0031] When the motor 3 drives the crushing wheel 10 to rotate, the crushing wheel 10 continuously impacts and squeezes the ore with the outer wheel 1003. At this time, the outer wheel 1003 rotates under the action of external force, so that the ore debris can be conveyed between the outer wheel 1003 and the housing under the action of the edge of the outer wheel 1003 for extrusion, making the ore debris more thoroughly crushed instead of being directly knocked flying, breaking the ore by the impact force, and at the same time reducing the wear of the ore on the surface of the outer wheel 1003 and improving the service life of the crushing wheel 10..

[0032] The above has described in detail an embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
