The design is specifically a mineral sizer crusher with crushing size, which solves the problems of complex structure and easy leakage leading to system failure caused by the existing crusher using hydraulic workstation to adjust spindle center distance. Including the upper guide rail and the lower guide rail, the upper guide rail and the lower guide rail is arranged between the left end and the two fixed cylinder bracket, the upper guide rail and the lower guide rail is arranged between the right end of the fixed bracket and the fixed bracket is arranged on the left side of the fixed bracket sliding between the upper guide rail and the lower guide rail, the movable bracket and the fixed bracket are provided with parallel tooth roller assembly, A bidirectional hydraulic cylinder connected with the tooth roll assembly of the movable support is fixed on the cylinder support, and a hand oil pump connected with the bidirectional hydraulic cylinder is arranged on the movable support. The utility model has the advantages of reasonable and reliable structure design, convenient and rapid adjustment and positioning of the center distance between the two main spindles, and effectively improves the reliable performance and service life of the equipment.
The existing tooth roller spindle of mining double-tooth roller crusher is mainly fixed and adjustable structure, and some adjustable structures mainly use hydraulic workstation as power source, which is complicated in structure and control system. At the same time, the hydraulic workstation is prone to oil leakage, leading to system failure, which brings difficulties for convenient adjustment of tooth roller center distance and reliable locking.
The utility model provides mineral sizer crusher with crushing size in order to solve the problems of complex structure and easy leakage resulting in system failure caused by the use of hydraulic workstation to adjust the center distance of the main shaft in the existing crusher. The new model is realized by using the following technical solutions: mineral sizer crusher mineral sizer crusher, including upper guide rail and lower guide rail, is arranged between the upper guide rail and the lower guide rail is located in the left end and the two fixed cylinder bracket, between the upper guide rail and the lower guide rail is arranged in the right end and fixed with the two fixed bracket, The left side of the fixed support is provided with a movable support sliding between the upper guide rail and the lower guide rail, the movable support and the fixed support are arranged on the tooth roller assembly parallel to each other, the cylinder support is fixed with a two-way hydraulic cylinder connected with the tooth roller assembly of the movable support, and the movable support is provided with a hand oil pump connected with the two-way hydraulic cylinder. When adjusting the spacing of the two-tooth roller assembly of the double-tooth roller crusher, the hand oil pump drives the two-way hydraulic cylinder to expand, and then drives the movable support and the tooth roller assembly to move around along the upper guide rail and the lower guide rail, convenient and fast to realize the adjustment of center distance, which overcomes the existing crusher adopts the hydraulic workstation to adjust the center distance of the spindle and the problems of complex structure and easy leakage leading to system failure. The gear roller assembly comprises a motor, a reducer, a coupler is arranged between the motor output shaft and the reducer input shaft, the output shaft of the reducer is connected with a main shaft, the main shaft is covered with its fixed crushing teeth, the main shaft is covered with a bearing seat, the bearing seat of the fixed support is provided with adjusting bolts. When the center distance between the two spindles is adjusted to the specified position, turn the adjusting bolt until it is close to the bearing seat of the movable support for auxiliary positioning, and overload protection of the spindle through the coupler. Mineral sizer crusher has reasonable and reliable structure design, convenient and rapid adjustment and positioning of the center distance between the two spindle, and overload protection of the spindle, which effectively improves the reliable performance and service life of the equipment, reduces the production cost and improves the economic benefits.
