Description

一种便于调节动态平衡的反击式破碎机 技术领域
本发明涉及破碎机技术领域，尤其涉及一种便于调节动态平衡的反击式破碎机。
背景技术
目前，反击式破碎机利用高速旋转的转子对投进破碎腔内的物料产生高速冲击，并把物料抛射到反击板上，物料受重力和反弹力落下来，但高速旋转的转子带动板锤沿切线方向再次撞击物料，把物料抛向另一块反击板，物料被进一步破碎，然后又从反击板反弹到板锤，重复上述过程，在该过程中由于物料受到板锤的打击、反击板的冲击以及物料相互之间的碰撞，物料不断产生裂缝，直至松散粉碎。在破碎机进行工作或者工作一段时间转子上的板锤发生较大的磨损时，通常需要检测转子是否能保持动态平衡，如果工作时转子无法保持动态平衡，破碎机会产生较大的震动力从而导致一些事故的发生，现有的破碎机调节平衡麻烦，需要停机较长的时间，使得破碎机的工作效率下降。
发明内容
本发明要解决上述现有技术存在的问题，提供一种便于调节动态平衡的反击式破碎机，该装置结构设计合理、使用方便快速，可以快速调节转子的动态平衡，缩短破碎机的维修时间，增加破碎机的工作效率。
本发明解决其技术问题采用的技术方案：这种便于调节动态平衡的反击式破碎机，包括机架总成和位于机架总成内侧的转子总成，转子总成包括转子以及固定在转子外侧的板锤，所述机架总成包括机架、开在机架上端右侧的投料口和开在机架下端中心位置的出料口，所述转子总成与机架之间形成破碎腔，所述破碎腔内壁上固定连接有反击板，所述转子前端开有若干个均匀设置的放置孔，所述放置孔内侧固定连接有配重块，设有开在所述转子上的放置孔，放置孔内设有配重块，当转子在长时间的工作后需要调节动态平衡时，只需根据需求调节放置孔内的配重块的大小和位置即可保持转子的动态平衡，从而使得破碎机可以正常的进行工作。
为了进一步完善，板锤设有两个，所述板锤关于转子呈中心对称设置，右端所述板锤 位于转子右端下侧，所述板锤左高右低倾斜设置在所述转子外侧，设有两个对称设置的板锤，使得转子在工作时可以保持平衡，而且减少了板锤的数量可以使得物流在撞击反击板后有足够的时间下落至板锤的内侧，从而使得板锤对物料的打击力增大，增强破碎效果。
进一步完善，配重块包括若干个前后通过螺纹连接的连接块，若干个所述连接块前后两端外侧均开有限位槽，限位槽内侧固定连接有橡胶圈，前端所述连接块上开有内凹槽，所述内凹槽左右两端内壁上设有用于握持和转动连接块的把手部，前端所述连接块前端外侧螺纹连接在所述放置孔内侧，所述配重块通过若干个连接块螺纹连接组成，使得配重块的大小质量可以根据需求进行调节，连接块外侧设有卡接在限位槽内侧的橡胶圈，可以使得位于放置孔内侧的配重块在转子发生转动时不发生移动，从而保证转子的正常运转，所述连接块前端通过螺纹连接在放置孔内，避免配重块在转子转动时从放置孔内脱落，设有的内凹槽和把手部则方便配重块的取出和放置。
进一步完善，投料口的下侧面上设有加长导料板，设有加长导料板，使得大颗粒物料在进入投料口时的速度更快，从而与板锤发生撞击时的冲击力更大，大颗粒物料破碎的更加完全。
进一步完善，机架前后两端上侧开有通过铰链与机架连接的检修门，所述检修门下端位于放置孔水平面以下的位置，设有检修门，检修门的下端位于放置孔下端，方便对转子上的配重块进行拿取进行重新调平配重。
进一步完善，转子外侧固定连接有靠背的一端，所述靠背的另一端与所述板锤的一个侧面固定连接，所述板锤另一个侧面为用于撞击物料的撞击面，撞击面的朝向与转子工作时的转动方向一致，设有靠背，使得板锤受力后可以将冲击力传递到靠背上，从而避免板锤长时间使用后发生弯曲或者断裂。
进一步完善，加长导料板左端工作平面上开有分离槽，所述加长导料板前后两端固定连接有密封板，所述板锤右端设有位于所述分离槽下端的过滤孔，所述过滤孔内侧设有筛选装置，所述筛选装置右端设有开在所述机架内侧的出料通道，设有分离槽，使得从投料口进入破碎腔的小颗粒物料可以进入分离槽内，并通过分离槽的导向作用流向筛选装置，最后通过筛选装置和出料通道流出破碎腔，从而增大破碎腔内可以容纳待物料的量，从而增加该装置的破碎效率。
进一步完善，板锤的撞击面上设有从内向外逐渐升高的阶梯面，所述阶梯面上固定连接有第二反击板，在板锤上设有高低不平的阶梯面，由于板锤外侧的阶梯面较长，所以板锤旋转后外侧的阶梯面首先撞击到物料表面，由于外侧的阶梯面处于力臂较长的位置，所以外侧的阶梯面对物料产生的撞击力较大，更容易使得物料破碎，而且当物料同时撞击在两个阶梯面上时，由于不同阶梯面的撞击力大小不同，使得物料更容易进行破碎。
进一步完善，筛选装置包括固定连接在所述过滤孔内侧的第一筛条，所述第一筛条上端固定连接有与所述第一筛条的垂直设置的第二筛条，所述第二筛条的安装方向与转子的旋转方向相同，设有相互垂直的第一筛条和第二筛条，使得部分小颗粒物料容易从筛选装置内落出，上端第二筛条的安装方向与转子的转动方向以及物料下落方向相同，使得小颗粒物料更容易进入第一筛条和第二筛条之间的空隙中，加快筛选速度，从而避免小颗粒物料占据破碎腔的空间，使得破碎腔可以容纳更多的待破碎物料。
进一步完善，第一筛条和第二筛条分别为倒三角形设置，设有倒三角设置的筛条，避免物料堵塞在筛条之间，从而避免筛条的筛选速度降低。
本发明有益的效果是：本发明结构设计合理、使用方便，设有开在所述转子上的放置孔，放置孔内设有配重块，当转子在长时间的工作后需要调节动态平衡时，只需根据需求调节放置孔内的配重块的大小和位置即可保持转子的动态平衡，从而使得破碎机可以正常的进行工作，缩短破碎机的维修时间，增加破碎机的工作效率。

如图1和3所示，机架3前后两端上侧开有通过铰链与机架3连接的检修门16，所述检修门16下端位于放置孔8水平面以下的位置，设有检修门16，检修门16的下端位于放置孔8下端，方便对转子1上的配重块9进行拿取进行重新调平配重。
如图4所示，转子1外侧固定连接有靠背17的一端，所述靠背17的另一端与所述板锤2的一个侧面固定连接，所述板锤2另一个侧面为用于撞击物料的撞击面，撞击面的朝向与转子1工作时的转动方向一致，设有靠背17，使得板锤2受力后可以将冲击力传递到靠背17上，从而避免板锤2长时间使用后发生弯曲或者断裂。
如图1-4所示，加长导料板15左端工作平面上开有分离槽18，所述加长导料板15前后两端固定连接有密封板19，所述板锤2右端设有位于所述分离槽18下端的过滤孔20，所述过滤孔20内侧设有筛选装置21，所述筛选装置21右端设有开在所述机架3内侧的出料通道22，设有分离槽，使得从投料口4进入破碎腔6的小颗粒物料可以进入分离槽18内，并通过分离槽18的导向作用流向筛选装置21，最后通过筛选装置21和出料通道22流出破碎腔6，从而增大破碎腔6内可以容纳待物料的量，从而增加该装置的破碎效率。
如图4所示，板锤2的撞击面上设有从内向外逐渐升高的阶梯面23，所述阶梯面23上固定连接有第二反击板24，在板锤2上设有高低不平的阶梯面23，由于板锤2外侧的阶梯面23较长，所以板锤2旋转后外侧的阶梯面23首先撞击到物料表面，由于外侧的阶梯面23处于力臂较长的位置，所以外侧的阶梯面23对物料产生的撞击力较大，更容易使得物料破碎，而且当物料同时撞击在两个阶梯面23上时，由于不同阶梯面23的撞击力大小不同，使得物料更容易进行破碎。
如图5所示，筛选装置21包括固定连接在所述过滤孔20内侧的第一筛条25，所述第一筛条25上端固定连接有与所述第一筛条25的垂直设置的第二筛条26，所述第二筛条26的安装方向与转子2的旋转方向相同，设有相互垂直的第一筛条25和第二筛条26，使得部分小颗粒物料容易从筛选装置21内落出，上端第二筛条26的安装方向与转子1的转动方 向以及物料下落方向相同，使得小颗粒物料更容易进入第一筛条25和第二筛条26之间的空隙中，加快筛选速度，从而避免小颗粒物料占据破碎腔6的空间，使得破碎腔6可以容纳更多的待破碎物料。
如图8所示，第一筛条25和第二筛条26分别为倒三角形设置，设有倒三角设置的筛条，避免物料堵塞在筛条之间，从而避免筛条的筛选速度降低。
本发明在使用前，只需在工作前根据需求通过再不同放置孔上放置不同质量的配重块对转子进行动态平衡调节，调节完成后即可进行使用，使用时，容纳腔6内的转子1高速旋转，物料从加长导料板15上滑落，滑落的过程中，小颗粒物料在重力的作用下进入分离槽18内侧，顺着分离槽18滑向筛选装置21，经过筛选装置21和出料通道22内侧从机架3内落出，而大颗粒的物料则从投料口4内进入容纳腔6后与板锤2发生撞击进行第一次破碎，破碎后的物料在板锤2的作用下反弹到容纳腔6的内壁上进行第二次破碎，第二次破碎后的物料在反击板7的作用下反弹到旋转一圈后的板锤2的作用面上进行第三次破碎，最后经过多次破碎后，物料从底部的出料口5落出，在经过长时间的使用后，板锤2发生较大的磨损需要对转子进行动态平衡调节时，只需打开检修门16，将放置孔8内的配重块9按照要求进行重新放置和配重即可使得磨损后的转子1重新实现动态平衡，从而可以继续进行破碎工作。
虽然本发明已通过参考优选的实施例进行了图示和描述，但是，本专业普通技术人员应当了解，在权利要求书的范围内，可作形式和细节上的各种各样变化。
