Crushing trolleys are usually equipped with hydraulically driven robotic arms, on which hydraulic breakers or other crushing tools are mounted for efficient crushing of ores. However, in actual operation, the hydraulic cylinder of the robotic arm is often directly exposed, and the moving end of the cylinder is easily impacted by ore debris generated during the crushing process. This causes ore debris to easily adhere to the moving end of the cylinder, resulting in cylinder wear and seriously affecting the service life and working efficiency of the equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please see Figure 1A mining crushing trolley with protective functions includes: a mobile device 1 (vehicle body), on which a mechanical arm 2 is mounted; the mechanical arm 2 includes several support arms, and a second hydraulic cylinder 6 is hinged between adjacent support arms. The second hydraulic cylinder 6 extends and retracts, and can adjust the included angle between adjacent support arms. Two support arms at both ends of the mechanical arm 2 are hinged, one to the mobile device 1, and a first hydraulic cylinder 3 (used to drive the mechanical arm 2 to move and change its pitch angle) is hinged between the mobile device 1 and the support arm, and the other to a crushing head 4 (the crushing head 4 is a component used during crushing operations on the crushing trolley), and a third hydraulic cylinder 7 (used to drive the crushing head 4 to change its angle) is hinged between the support arm and the crushing head 4.

[0021] It should be noted that the crushing head 4 is detachably mounted on the support arm, allowing it to be removed; there are at least two support arms.

[0022] Please see Figure 1 and Figure 2 The first hydraulic cylinder 3, the second hydraulic cylinder 6, and the third hydraulic cylinder 7 are all equipped with hinges (such as pins) on both their moving and fixed ends. The hinges are used to connect the first hydraulic cylinder 3, the second hydraulic cylinder 6, and the third hydraulic cylinder 7 to the mobile device 1, the support arm, and the crushing head 4. The hinges located at the moving ends of the first hydraulic cylinder 3, the second hydraulic cylinder 6, and the third hydraulic cylinder 7 are all equipped with guards 5. The three sets of guards 5 are located on the side of the first hydraulic cylinder 3, the second hydraulic cylinder 6, and the third hydraulic cylinder 7 away from the robotic arm 2, respectively, and are used to protect the moving ends of the first hydraulic cylinder 3, the second hydraulic cylinder 6, and the third hydraulic cylinder 7.

[0023] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 The protective part 5 is detachably connected to the hinge, so that the protective part 5 can be removed.

[0024] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 The length extension direction of the three sets of protective parts 5 is parallel to the extension and retraction direction of the first hydraulic cylinder 3, the second hydraulic cylinder 6 and the third hydraulic cylinder 7 respectively. The protective parts 5 are set on the hinge. When the support arm and the crushing head 4 and other components rotate, the protective parts 5 are still parallel to the extension and retraction direction of the first hydraulic cylinder 3, the second hydraulic cylinder 6 and the third hydraulic cylinder 7, so as to avoid the protective parts 5 from contacting and being squeezed by the components parallel to the first hydraulic cylinder 3, the second hydraulic cylinder 6 and the third hydraulic cylinder 7.

[0025] In this embodiment, as a further optimization, please refer to... Figure 1 The lengths of the three sets of protective components 5 are greater than the moving ends of the first hydraulic cylinder 3, the second hydraulic cylinder 6, and the third hydraulic cylinder 7, respectively, to ensure that the protective components 5 can protect the moving ends of the first hydraulic cylinder 3, the second hydraulic cylinder 6, and the third hydraulic cylinder 7.

[0026] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2 The protective component 5 includes a main baffle 51, two side baffles 52 respectively provided on both sides of the main baffle 51, and a connector 53 provided on one end of the main baffle 51; the connector 53 is located on the side of the main baffle 51 facing the support arm, and the main baffle 51 and the connector 53 form an L shape.
