The outer side of the disc 3. Thus, since the flange 41 is formed on the columnar member 42, the lock sleeve 4 can be positioned in one axial direction by locking the flange 41 to the outer side surface of the outer cutter 3.
如图 1、 图 4和图 6所示， 所述粉碎机的转子 1还具有一个以上的板状的内刀盘 6 (本实施方式中为 5个），所述内刀盘 6固定设置在旋转轴 2上且位于两个所述外刀 盘 3之间， 内刀盘 6与相邻的内刀盘 6和外刀盘 3之间通过刀盘隔套 10而隔开预定 间隔， 所述内刀盘 6在周向设有多个开口部 62， 所述多个开口部 62供刀片轴 5进入 或脱出， 该内刀盘 6的开口部 62与所述外刀盘 3的开口部 32轴向对应。  As shown in FIG. 1, FIG. 4 and FIG. 6, the rotor 1 of the pulverizer further has one or more plate-shaped inner cutter discs 6 (five in the present embodiment), and the inner cutter disc 6 is fixedly disposed at On the rotating shaft 2 and between the two outer cutter discs 3, the inner cutter disc 6 and the adjacent inner cutter disc 6 and the outer cutter disc 3 are separated by a predetermined interval by the cutter disc spacer 10, The inner cutter disc 6 is provided with a plurality of opening portions 62 in the circumferential direction, and the plurality of opening portions 62 allow the blade shaft 5 to enter or escape. The opening portion 62 of the inner cutter head 6 and the opening portion 32 of the outer cutter head 3 are axially correspond.
这样， 由于在内刀盘 6设有多个开口部 62， 因此刀片轴 5可以直接进入到各内 刀盘 6的开口部 62的内部， 而无需像以往那样使刀片轴 5依次穿过各个刀盘地进行 安装， 能够节省大量时间， 降低安装作业难度。  Thus, since the inner cutter disc 6 is provided with the plurality of opening portions 62, the insert shaft 5 can directly enter the inside of the opening portion 62 of each inner cutter disc 6, without the need to sequentially pass the insert shaft 5 through the respective cutters as in the prior art. Installation on the floor can save a lot of time and reduce the difficulty of installation.
如图 3所示， 所述外刀盘 3具有多个周向分布的径向向外突出的叶片 31， 在每 个叶片 31上设置所述开口部 32。 所述外刀盘 3的开口部 32的开口朝向外刀盘 3的 大致径向内侧。  As shown in Fig. 3, the outer cutter disc 3 has a plurality of circumferentially distributed radially outwardly projecting vanes 31 on which the opening portions 32 are provided. The opening of the opening portion 32 of the outer cutter head 3 faces the substantially radially inner side of the outer cutter head 3.

The opening of the opening portion 62 of the inner cutter disc 6 faces the substantially radially inner side of the inner cutter head 6. In the illustrated example, the opening of the inner cutter head 6 is U-shaped. As shown in Fig. 6, during the assembly of the rotor, when the blade shaft 5 is in contact with the innermost portion (i.e., the arcuate portion of the opening portion 32) of the U-shaped opening portion 32 of each of the inner cutter discs 6, the lock can be just made The locking portion 44 of the tight sleeve 4 is axially inserted into the engaging portion 322 of the opening portion 32 of the outer cutter head 3, and the end portion of the blade shaft 5 is brought into the axial joint portion 43 of the lock sleeve 4.
根据这样的结构， 能够便于刀片轴 5从内刀盘 6的开口部进入和脱出， 并且， 在 转子 1旋转时， 当刀片轴 5受到离心力影响而欲向径向外侧挠曲时， U形的开口部能 够对刀片轴 5提供朝向刀盘径向内侧的与上述离心力相平衡的力，从而抑制了刀片轴 5的挠曲， 提高了刀片轴 5的整体刚性。  According to such a configuration, it is possible to facilitate the entry and exit of the blade shaft 5 from the opening portion of the inner cutter head 6, and, when the rotor 1 rotates, when the blade shaft 5 is subjected to centrifugal force and is to be deflected radially outward, U-shaped The opening portion can supply the blade shaft 5 with a force that is balanced toward the centrifugal force on the radially inner side of the cutter head, thereby suppressing the deflection of the blade shaft 5 and improving the overall rigidity of the blade shaft 5.
如图 6所示， 在所述刀片轴 5的两端部分别设有一个沿轴径向贯通的贯通孔 51， 将销等定位件（未图示）***于贯通孔 51， 从而同时将锁紧套 4和刀片轴 5在轴向 定位。 当然， 也可以通过其他结构来实现锁紧套 4和刀片轴 5的轴向固定。例如， 可 以不设置贯通孔 51和销，而是通过在刀片轴 5的两端的从外刀盘 3露出的部分（即， 大致贯通孔 51附近的部分） 设置外螺纹， 并将防松螺母旋紧到该外螺纹部分直至抵 接到锁紧套 4， 从而将锁紧套 4和刀片轴 5在轴向固定。 此外， 也可以在锁紧套 4上 开设盲孔来代替贯通孔， 同时在锁紧套 4 的凸缘上设置卡扣， 并相应地在外刀盘 3 上设置于该卡扣配合的卡孔， 通过卡扣和卡孔的卡合来实现锁紧套 5的轴向固定。 As shown in FIG. 6, a through hole 51 penetrating in the radial direction of the shaft is respectively disposed at both end portions of the blade shaft 5, A positioning member (not shown) such as a pin is inserted into the through hole 51, thereby simultaneously positioning the locking sleeve 4 and the blade shaft 5 in the axial direction. Of course, the axial fixing of the locking sleeve 4 and the blade shaft 5 can also be achieved by other structures. For example, the through hole 51 and the pin may not be provided, but the external thread may be provided by a portion exposed from the outer cutter 3 at both ends of the blade shaft 5 (that is, a portion substantially near the through hole 51), and the locknut may be rotated. The external threaded portion is tightened until it abuts against the locking sleeve 4, thereby fixing the locking sleeve 4 and the blade shaft 5 in the axial direction. In addition, a blind hole may be formed in the locking sleeve 4 instead of the through hole, and a buckle is arranged on the flange of the locking sleeve 4, and correspondingly disposed on the outer cutter head 3 in the snap-fitted card hole. The axial fixing of the locking sleeve 5 is achieved by the engagement of the buckle and the card hole.
根据这样的结构，能够以简单的结构防止锁紧套 4和刀片轴 5在转子 1旋转时因 震动等而沿轴向脱出。  According to such a configuration, it is possible to prevent the lock sleeve 4 and the blade shaft 5 from coming out in the axial direction due to vibration or the like when the rotor 1 rotates with a simple structure.
本发明的转子 1能够应用于粉碎机， 从而能够快速地装拆粉碎机的转子 1， 便于 维修和更换。  The rotor 1 of the present invention can be applied to a pulverizer, so that the rotor 1 of the pulverizer can be quickly assembled and disassembled for maintenance and replacement.
本公开的描述仅为示例性的属性，因此没有偏离本公开要旨的各种变形理应在本 公开的范围之内。 这些变形不应被视为偏离本公开的精神和范围。  The description of the present disclosure is intended to be illustrative only, and various modifications that do not depart from the gist of the present disclosure are intended to be within the scope of the present disclosure.
