[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 2 to Figure 5 As shown, this embodiment proposes a material collection drive device for a coal and rock tunneling machine, and its structure includes a frame 1. The cutting structure in this embodiment is arranged on the frame 1 to cut stones. The transport structure is arranged on the frame 1 to transport stones. The aggregate structure is arranged between the cutting structure and the transport structure to collect stones. The material guide structure is arranged on the aggregate structure and between the transport structure to guide stones from the aggregate structure to the transport structure. The control box 7 is fixedly arranged on the material guide structure, the first cleaning rod 81 and the second cleaning rod 82 are rotatably arranged in the control box 7, the synchronization structure is arranged in the control box 7 to synchronize the rotation of the first cleaning rod 81 and the second cleaning rod 82, and the driving structure is arranged in the control box 7 to drive the synchronization structure.

[0028] The aggregate structure in this embodiment includes an aggregate shovel 4, which is fixedly connected to the frame 1. A limit plate 41 is fixedly arranged on the outer periphery of the aggregate shovel 4 to reduce the crushed materials from escaping from the aggregate shovel 4 after the crushed materials are shoveled into the aggregate shovel 4.

[0029] The cutting structure in this embodiment includes a cutting head 3, a connecting member 2 rotatably arranged on a frame 1, the cutting head 3 is rotatably connected to the connecting member 2, the cutting head 3 is a semi-elliptical structure, a cutting blade 31 is fixedly arranged on the cutting head 3, and the cutting blade 31 is spirally distributed along the central axis of the cutting head 3. In this embodiment, the cross section of the cutting opening close to the end of the stone to be cut is smaller, which can be more accurately aligned with the stone to be cut to avoid mixing with other nearby materials when cutting.

[0030] The first cleaning rod 81 and the second cleaning rod 82 in the present embodiment have the same length and are parallel to each other. The synchronous structure includes a first connecting rod 83, a rotation notch 71 is arranged on the control box 7, a first rotating end 811 is arranged at the end of the first cleaning rod 81, and a second rotating end 821 is arranged at the end of the second cleaning rod 82. The two ends of the first connecting rod 83 are respectively connected to the first rotating end 811 and the second rotating end 821 for rotation. The third rotating end 812 is arranged on the first cleaning rod 81, and the fourth rotating end 822 is arranged on the second cleaning rod 82. The distance between the third rotating end 812 and the first rotating end 811 is less than the distance between the third rotating end 812 and the first cleaning rod 81 away from the end of the control box 7, and the distance between the fourth rotating end 822 and the second rotating end 821 is less than the distance between the fourth rotating end 822 and the second cleaning rod 82 away from the control box 7, which is used to realize the control of the rotation of the first cleaning rod 81 and the second cleaning rod 82 with a smaller displacement. Such a design can synchronously control the rotation of the first cleaning rod 81 and the second cleaning rod 82, reduce the number of driving devices, and reduce manufacturing costs.

[0031] The driving structure in this embodiment includes a telescopic member 9, the fixed end of the telescopic member 9 is fixedly connected to the control box 7, and the second connecting rod 84 is rotatably arranged between the telescopic end of the telescopic member 9 and the first rotating end 811. The telescopic member 9 in this embodiment is preferably a hydraulic cylinder or a cylinder. The hydraulic cylinder or cylinder in this embodiment is all prior art, and this embodiment will not be described in detail. In this embodiment, the first cleaning rod 81 and the second cleaning rod 82 are rotated from 0 to 90 degrees by the telescopic member 9, and the cleaning of the aggregate structure can be achieved by repeatedly telescoping the telescopic member 9.

[0032] The transport structure in this embodiment includes a conveyor belt 5, and a placement notch 42 is provided at the end of the aggregate shovel 4 close to the frame 1, so as to facilitate the rotation of the first cleaning rod 81 and the second cleaning rod 82. One end of the conveyor belt 5 is placed in the placement notch 42, and the horizontal height of the end of the conveyor belt 5 close to the aggregate shovel 4 is lower than the horizontal height of the end of the first aggregate shovel 4 close to the conveyor belt 5. By utilizing the horizontal height difference, when the material is introduced by the guide structure to the vicinity of the placement notch 42, it will fall on the conveyor belt 5 under the action of gravity and be transported away by the conveyor belt 5, which makes the transportation of materials more convenient.

[0033] The guide structure in this embodiment includes a first guide blade 61 and a second guide blade 62, both of which are arranged on the aggregate shovel 4. The first guide blade 61 and the second guide blade 62 are both rotatably connected to the aggregate shovel 4, and the first guide blade 61 and the second guide blade 62 have the same diameter. The first guide blade 61 and the second guide blade 62 are respectively placed at both ends of the placement gap 42. The design of the guide blades at both ends enables the stones at both ends of the aggregate shovel 4 to rotate with the first guide blade 61 or the second guide blade 62, and drive and enter the conveyor belt 5, which is convenient for transportation.

[0034] The working process of this embodiment is as follows: when it is necessary to mine stones, the cutting head 3 is first rotated to crush the stones, and then the crushed fragments are collected by the aggregate shovel 4. If there are large-volume crushed stones at this time, the telescopic rod is started, and the telescopic end of the telescopic rod is extended and retracted to drive the second connecting rod 84 to move, so that the first rotating end 811 rotates and drives the first cleaning rod 81 and the second cleaning rod 82 to rotate at the same time. Since the large-volume crushed stones are higher than the rest of the crushed stones, the first cleaning rod 81 and the second cleaning rod 82 can drive the larger particles of stones to leave the aggregate shovel 4 when they rotate. After cleaning is completed, the crushed materials are introduced into the conveyor belt 5 by rotating the first guide blade 61 and the second guide blade 62.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
