In this embodiment, the bumper 164 includes a rubber 166 therein. Specifically, the rubber member 166 is disposed on the anti-collision side of the anti-collision member 164, and since the rubber member 166 has good elasticity, an effective buffer can be formed when the anti-collision member 164 is collided, so that damage to the anti-collision member 164 when the anti-collision member receives the collision is reduced, and the anti-collision performance of the entire anti-collision mechanism 100 is improved.

By including the rubber member 166 in the impact prevention member 164, an effective buffer can be formed when the impact prevention member 164 is impacted by using the elasticity of the rubber member 166, so that damage to the impact prevention member 164 caused by the impact is reduced, and damage to the material transporting vehicle caused by the impact of the material transporting vehicle on the impact prevention member 164 is also reduced. The crashworthiness of the entire crashworthiness mechanism 100 is improved.

In practical applications, the rubber member 166 is fixed to the impact prevention member 164 by a self-counterbore and a hexagon socket head cap screw. The buffer function is realized when the material transporting vehicle is backed excessively and collides with the anti-collision piece 164, the tail part of the heading machine 200 and the tail part of the material transporting vehicle can be prevented from being damaged due to rigid collision, and the anti-collision performance of the whole anti-collision mechanism 100 is further improved.

Alternatively, stepped holes are formed in the rubber member 166, and bolts are passed through the stepped holes to fix the rubber member 166 to the bumper member 164, the stepped holes being formed so that the bolts are sunk in the rubber member 166. The rubber member 166 serves as a buffer in the event of an excessive reverse collision of the truck.
