[0040] The crawler travel system 1 is installed at the bottom of the vehicle body frame 2 to complete the function of the whole vehicle traveling.

[0041] A set of repair arms 5 are respectively arranged at both ends of the vehicle body frame 2. The repair arm 5 is connected to the vehicle body frame 2 through a swing oil cylinder 7 to realize the left and right adjustment of the repair arm 5. Specifically, one end of the repair arm 5 is installed on the vehicle body frame 2 through a connecting seat 2.1. The connecting seat 2.1 can move left and right relative to the vehicle body frame 2. The connecting seat 2.1 is also connected to the swing oil cylinder 7 installed on the vehicle body frame 2, and the position of the connecting seat 2.1 is adjusted left and right by the telescopic movement of the swing oil cylinder 7.

[0042] A set of dozer blades 3 are respectively installed at both ends of the vehicle body frame 2 at positions below the repair arms 5. Specifically, one end of the dozer blade 3 is hinged to the vehicle body frame 2, and the other end is hinged to the dozer blade oil cylinder 4 installed on the vehicle body frame 2. The dozer blade 3 is driven to rotate around its connection with the vehicle body frame 2 by the telescopic movement of the dozer blade oil cylinder 4, so as to adjust the angle of the dozer blade 3. The dozer blade 3 is used to level the obstacles in front during the whole vehicle traveling process, and can also play a role in keeping the vehicle body stable during the work of the whole vehicle.

[0043] As Figure 3As shown in the figure, the repair arm 5 includes a connecting seat 2.1, a stretching oil cylinder a 2.2, a connecting arm 2.3, a stretching oil cylinder b 2.4, a transfer frame 2.5, a stretching oil cylinder c 2.6 and a quick-change seat 2.7. One end of the connecting arm 2.3 is hinged to the connecting seat 2.1, and the other end is hinged to one end of the transfer frame 2.5. The other end of the transfer frame 2.5 is equipped with a quick-change seat 2.7. One end of the stretching oil cylinder a 2.2 is hinged to the connecting seat 2.1, and the other end is hinged to the connecting arm 2.3. One end of the stretching oil cylinder b 2.4 is hinged to the connecting arm 2.3, and the other end is hinged to the transfer frame 2.5. One end of the stretching oil cylinder c 2.6 is hinged to the transfer frame 2.5, and the other end is hinged to the quick-change seat 2.7. The connecting arm 2.3, the transfer frame 2.5 and the quick-change seat 2.7 are respectively driven by the stretching oil cylinder a 2.2, the stretching oil cylinder b 2.4 and the stretching oil cylinder c 2.6 to adjust their respective angles. The quick-change seat 2.7 is connected to the quick-change device to complete the required work. Corresponding to the work to be carried out on site, the corresponding quick-change device is selected for quick-change connection. For example, in this embodiment, the quick-change device is a ground drum crushing device 11 and a bucket device 6, which are respectively installed on two groups of repair arms 5. The crushing device 11 is used to realize the grasping and cleaning of crushed materials, and the bucket device 6 can realize the crushing function.

[0044] As Figure 4 and 5 shown in the figure, the bucket device 6 includes a quick-change connection seat 3.1, a slewing speed reducer 3.2, a swing oil cylinder 3.3, a bucket arm 3.4, a bucket arm extension oil cylinder 3.5, a bucket clamping oil cylinder 3.6 and a bucket 3.7.

[0045] The quick-change connecting seat 3.1 is hinged to the quick-change seat 2.7 of the repair arm 5, thereby quickly installing the bucket device 6 on the repair arm 5. Through the internal self-rotation function of the slewing speed reducer 3.2 installed on the repair arm 5, a 360° rotation action of the bucket device 6 is achieved. Specifically, the slewing speed reducer 3.2 is installed on the quick-change connecting seat 3.1, and the swing oil cylinder 3.3 is connected to the bucket arm 3.4 through the slewing speed reducer 3.2. Through the rotatable angle function of the swing oil cylinder 3.3 itself, a ±90° action of the bucket device 6 in the vertical direction is achieved. The above actions can complete the adjustment of the working angle of the bucket 3.7 in the horizontal direction. The bucket arm 3.4 is a telescopic structure, and a bucket arm extension oil cylinder 3.5 is built therein. The length of the bucket arm 3.4 is adjusted through the bucket arm extension oil cylinder 3.5 to adjust the length of the bucket 3.7 for grasping materials. At the same time, the bucket arm 3.4 is hinged to the bucket clamping oil cylinders 3.6 on both sides and the hinge shaft of the bucket 3.7. Through the extension and contraction of the bucket clamping oil cylinders 3.6, the opening and closing of the bucket 3.7 are controlled to achieve the grasping and cleaning of materials. Specifically, one end of the bucket clamping oil cylinder 3.6 is hinged to the bucket arm 3.4, and the other end is hinged to the side of the bucket 3.7. The bucket 3.7 is connected to the end of the bucket arm 3.4 through a hinge shaft and can rotate relative to the bucket arm 3.4. The bucket 3.7 realizes the opening and closing action under the drive of the bucket clamping oil cylinder 3.6. The bucket device 6 can not only clean the crushed residue of the ground drum under the belt but also grab the materials dropped under the belt and send them back to the belt conveyor, greatly reducing the working intensity of underground workers and improving the working efficiency at the same time.

[0046] The crushing device 11 adopts the prior art, and the specific structure thereof will not be described in detail in the present utility model.

[0047] As Figure 2 shown, the hydraulic system 8, the operating platform 9, and the electrical system 10 are all installed on the vehicle body frame 2. The electrical system 10 is connected to the hydraulic system 8, and the electrical system 10 sends an oil supply signal to the hydraulic system 8. The operating platform 9 controls the entire hydraulic system 8 and the electrical system 10. Through the hydraulic system 8 and the electrical system 10, the extension and contraction actions of the stretching oil cylinder a 2.2, the stretching oil cylinder b 2.4, and the stretching oil cylinder c 2.6 are controlled to achieve the up and down angle adjustment function of the repair arm 5, which can meet the use of the crushing device 11 and the bucket device 6 at horizontal and other working angles.

[0048] The utility model adopts the structures of double repair arms 5 and double bulldozing plates 3, and completes the crushing of the ground drum under the underground conveying belt bracket, and the grasping and cleaning of the residual materials and the falling materials after crushing through the crushing device 11 and the bucket device 6 on the equipment. First, park the vehicle in the area to be operated. Open the double bulldozing plates 3. For the repair arm 5 on the side with the crushing device 11, adjust the extended length through the oil cylinder on the repair arm 5 to make the breaker hammer in a horizontal state. The crushing device 11 horizontally extends under the conveying belt bracket, finds a suitable position, and starts the ground drum crushing operation. After the crushing is completed, drive the vehicle forward by the distance of one vehicle body, and then use the repair arm 5 with the bucket device 6 on the other side. Adjust the extended length through the oil cylinder on the repair arm 5 to make the bucket device 6 in a horizontal position under the conveying belt bracket (i.e., the position of the crushed residue of the ground drum). The bucket arm 3.4 has an extended action of the bucket arm extension oil cylinder 3.5 built-in, which can make the whole bucket 3.7 extend and translate. At the same time, the opening and closing state of the bucket 3.7 is controlled by the bucket clamping oil cylinders 3.6 on both sides to complete the grasping and cleaning of the materials after crushing under the belt. At the same time, the fallen coal blocks can also be grasped and sent to the belt. This is a working cycle. The double bulldozing plates 3 can not only ensure the function of shoveling and walking parallel to obstacles during the whole vehicle's walking, but also play the role of supporting the whole vehicle during the working process, ensuring the stability of the whole vehicle during the operation process.
