DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] See also Figure 1-2The utility model provides a technical solution: a graded tooth roller crusher for coal mines, comprising a box body 1, the bottom of the box body 1 is set to be open, the inside of the box body 1 is connected to two crushing shafts 2 through bearings, the outer sides of the two crushing shafts 2 are evenly provided with crushing teeth 3, and the crushing teeth 3 are spirally distributed along the outer sides of the crushing shafts 2, side tooth plates 4 are provided on both sides of the box body 1, a transmission structure 5 is provided between one ends of the two crushing shafts 2, a walking driving member 6 is provided on one side of the box body 1, a fixed seat 13 is fixed at one end of the box body 1, a reducer 7 is fixed on the fixed seat 13, the output shaft of the reducer 7 is connected to a crushing shaft 2 through two bevel gears, a protective cover 9 is connected to one side of the reducer 7 through a flange 8, a motor 10 is fixed to one side of the protective cover 9, a coupler 11 is fixed to the end of the output shaft of the motor 10, and the output end of the coupler 11 is connected to the input shaft of the reducer 7 through a coupling, and the transmission structure 5 includes a first synchronous gear 51 and a second synchronous gear 52, and the first synchronous gear 51 and the second synchronous gear 52 are respectively Fixed at one end of the two crushing shafts 2, the first synchronous gear 51 and the second synchronous gear 52 are of the same size and mesh with each other. When one crushing shaft 2 rotates, the same first synchronous gear 51 and second synchronous gear 52 can drive the second crushing shaft 2 to rotate. A protective shell 12 is fixed on one side of the casing 1 to protect the transmission structure 5. The transmission structure 5 is located inside the protective shell 12, and the transmission structure 5 can be protected by the protective shell 12. The travel drive member 6 includes a travel motor 61 fixed to the casing 1, and a travel gear 62 is fixed to the output shaft end of the travel motor 61. A track rack 63 is arranged below the travel gear 62, and the travel gear 62 meshes with the track rack 63. When walking, the travel motor 61 can drive the travel gear 62 to rotate, and the travel gear 62 can roll along the track rack 63, so as to drive the device to walk. The graded tooth roller crusher for coal mines has a simple structure, is novel and unique, has a low height, a small size, is easy to install, maintain and use, and has high production efficiency.

[0014] When in use: the rotation of the motor 10 can drive the coupler 11 and the reducer 7 to rotate, and the rotation of the reducer 7 can drive a crushing shaft 2 to rotate. When one crushing shaft 2 rotates, the same first synchronous gear 51 and second synchronous gear 52 can drive the second crushing shaft 2 to rotate. The rotation of the two crushing shafts 2 can drive the crushing teeth 3 to rotate. The raw materials can be crushed by the rotation of the crushing teeth 3 and the side tooth plate 4. After the material falls between the two crushing shafts 2 of the crusher, it is split by the crushing teeth 3 and sheared. Then, stretching crushing is performed to initially crush the larger particle size material to a size that can be bitten by the crushing shaft 2, and then the material is pushed to the crushing shaft 2 by the crushing teeth 3. As the crushing shaft 2 rotates, the volume contained by the crushing teeth 3 gradually changes to the smallest, and then increases again. The large-sized material is forcibly squeezed and crushed or sheared due to the gradually decreasing contained volume, and the crushed material leaks out from the gap on the side of the crushing teeth 3. Materials that are still larger than the discharge size will be blocked by the side tooth plate 4 during discharge, and the rotating crushing teeth 3 and the side tooth plate 4 work together to break up the larger materials and forcibly discharge them; at the same time, the crushing teeth 3 on the crushing shaft 2 are arranged in a spiral form, and the side thrust and shear force of the spiral can be used to bite large pieces of hard materials tightly, thereby increasing the effectiveness of the crushing teeth 3 and preventing large pieces of hard materials from rolling during the crushing process, thereby causing blockage and affecting the processing capacity; the portion of the feed that is smaller than the gap between the teeth is directly and quickly discharged through the teeth and the side tooth plate 4, thereby achieving the dual purposes of screening and crushing; since both tooth rollers are fixed, they can also be forced to crush when encountering hard materials, thereby avoiding the over-granulation phenomenon of the old tooth roller crusher and avoiding affecting production, the transmission structure 5 can be protected by the protective shell 12, and when walking, the travel motor 61 can drive the travel gear 62 to rotate, and the travel gear 62 can roll along the track rack 63, thereby driving the device to walk.

[0015] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
