箱体162的另一侧设置有防撞件164，在被撞击时，最先撞到的就是防撞件164，利用防撞件164的防撞性能，可以形成对箱体162、连接架120以及连接架120一侧的掘进机200机体的防撞保护。降低了在受到撞击时，对箱体162和连接架120的造成的破坏，尤其是很好的保护了掘进机200机体，解决了因掘进机200机体受到撞击而引起的维修成本和维修时间增加的问题，提高了重要设备的使用寿命，同时也提高了掘进机200的工作效率。
具体地，防撞件164与连接架120位于箱体162的相对两侧，通过防撞件164和连接架120将箱体162封堵，有效的提高了防撞件164整体的防撞强度。
在实际的应用中，在掘进机200的机尾部的连接架120增加防撞功能。具体地连接架120的一端与掘进机200的后支撑端122通过螺栓固定，在连接架120的另一端焊接箱体162，并将防撞件164焊接在箱体162的尾端，箱体162的前后两端封闭，可以提高箱体162结构强度，提升整体防撞机构100的防撞性能，保证运料车在过度倒车撞击防撞机构100时，箱体162可以保持不变形，进而很好的保护了掘进机200机体，节省了维修成本，提高了重要设备的使用寿命。而且，将箱体162焊接在连接架120上，将两个功能件集成到一个件上， 可以减少装配及加工工序。
进一步地，如图1和图3所示，在上述任一实施例中，防撞件164包括橡胶件166。
在该实施例中，防撞件164中包括橡胶件166。具体地，橡胶件166设置于防撞件164的防撞侧，因橡胶件166具有很好的弹性，在防撞件164被撞时可以形成一个有效的缓冲，减少防撞件164在收到撞击时受到的破坏，提高了整个防撞机构100的防撞性能。
通过在防撞件164中包括橡胶件166，利用橡胶件166的弹性，在防撞件164被撞时可以形成一个有效的缓冲，减少防撞件164在受到撞击时造成的破坏，同时也减轻了运料车在撞击防撞件164时引起的自身的损害。提高了整个防撞机构100的防撞性能。
在实际的应用中，橡胶件166通过自身沉孔和内六角螺栓固定在防撞件164上。在运料车过度倒车撞击防撞件164时起到缓冲作用，能够同时避免掘进机200尾部部件和运料车尾部因刚性撞击而损坏，进一步提升了整个防撞机构100的防撞性能。
可选地，在橡胶件166上加工若干阶梯孔，螺栓通过阶梯孔将橡胶件166固定在防撞件164上，阶梯孔应能让螺栓沉在橡胶件166中。橡胶件166在运料车过度倒车撞击时起到缓冲作用。
实施例5：
如图1所示，在实施例4的基础上，实施例5提供了一种防撞机构100，其中，连接架120呈L型。
在该实施例中，连接架120呈L型结构。其中，连接架120的水平端与掘进机200的后支撑相连接，连接架120的竖直端与运输机202相铰接。
通过设置L型结构的连接架120，一方面，L型结构连接架120因其结构简单，易于加工制作，便于批量成产，成本较低。另一方面，连接架120的竖直端与运输机202相铰接，运输机202能够以连接架120的支撑段为支点进行转动，方便运输机202卸货。
具体地，连接架120的水平端与掘进机200的后支撑采用焊接的方式固定连接。
在具体的应用中，如图1所示，L型结构的连接架120包括长边的支撑部和短边的连接部，长边的支撑部将连接架120的支撑端122位置抬高的同时，也使与支撑架的相连接的箱体162和防撞件164位置升高，随着防撞件164位置的升高，升高后的防撞件164可以与运料车车厢尾部的高度相适应，保证运料车在过度倒车时，最先撞到的就是防撞件164，能够充分发挥防撞件164的防撞特性，对掘进机200和运料车都能形成有效的防撞保护。
实施例6：
本申请的二个方面，提出了一种掘进机200，如图5所示，包括：主体210；运输机202，运输机202设置于主体210；以及如上述任一项实施例的防撞机构100，防撞机构100的连接架120与主体210相连接。

运输机202设置于主体210，主要用于掘进机200卸料。
防撞机构100的连接架120与主体210相连接。
因包括如上述第一方面的任一实施例的防撞机构100，所以具备该掘进机的防撞机构100的全部有益效果，在此不再赘述。
进一步地，运输机202包括：第二铰接孔204，设置于运输机202，第二铰接孔204与第一铰接孔146适配。
在该实施例，运输机202包括第二铰接孔204。第二铰接孔204设置于运输机202，与第一铰接孔146适配。
具体地，第二铰接孔204设置于运输机202的下部，在进行运输机202和铰接座144的装配时，使运输机202的第二铰接孔204与铰接部140的第一铰接孔146轴心相同，保证运输机202和铰接座144可以顺利装配。
在具体的应用中，如图2所示，防撞机构100包括2个铰接座144，相对应的，运输机202也需要设置2个铰接点与2个铰接座144相对应，也即，运输机202包括2个相邻的第二铰接孔204。
进一步地，如图2所示，在上述任一实施例中，掘进机200，还 包括：销轴206，设置于铰接部140，用于连接第一铰接孔146与第二铰接孔204；紧固件208，设置于销轴206与第一铰接孔146之间。
在该实施例中，掘进机200包括销轴206和紧固件208。销轴206用于连接第一铰接孔146与第二铰接孔204。
具体地，销轴206穿设于轴套内，在进行运输机202和铰接座144的装配时，使运输机202的第二铰接孔204与铰接部140的第一铰接孔146轴心相同，这样销轴206可以顺利穿设于第一铰接孔146与第二铰接孔204，保证运输机202和铰接座144可以顺利装配。
紧固件208，用于紧固，使销轴206无法在第二铰接孔204和第一铰接孔146轴心方向上移动。
在具体的应用中，如图2所示，本申请将设置在支撑端122上部的2个铰接座144，通过销轴206和衬套148直接与运输机202下部的第二铰接孔204连接，与相关技术相比，本申请减少了2个支撑板和2个销轴206，降低了掘进机200的成本和安装工作量。
