[0040] The specific implementation process of this utility model will be described below through several embodiments.

[0041] Example 1

[0042] See Figures 1 to 6 This embodiment discloses a specific implementation of an anchor bolt transfer device for coal mines.

[0043] See Figures 1 to 6 A coal mine anchor bolt transfer device includes a vehicle body 1, a receiving assembly 2, a conveying unit 3, a top anchor bolt assembly 4, a side anchor bolt assembly 5, and a crushing assembly 6. The receiving assembly 2 is located at the front end of the vehicle body 1 and includes a receiving hopper 21 with slopes 22 on both sides. The top anchor bolt assembly 4 is located above the front end of the vehicle body 1. The conveying unit 3 receives coal from the receiving assembly and passes it through the middle of the vehicle body. The side anchor bolt assemblies 5 are located on both sides of the rear end of the vehicle body 1. The crushing assembly 6 is located adjacent to the top anchor bolt assembly. The material receiving assembly 2 is positioned behind the material receiving assembly 2 and in front of the top anchor bolt assembly 4. The side anchor bolt assembly 5 includes a first side anchor part 51 and a second side anchor part 52 symmetrically arranged. The first side anchor part 51 includes a longitudinal sliding rail 511. During anchoring operations, the first side anchor part 51 can move back and forth via the longitudinal sliding rail 511. Even after the vehicle body 1 is slightly moved, it can still perform anchoring operations in place, achieving a balance between anchoring and transport. The top anchor bolt assembly 4 includes a central top anchor part 41 and a first top anchor part 42 and a second top anchor part 43 symmetrically arranged on both sides of the central top anchor part 41.

[0044] Specifically, see Figures 1 to 5In this embodiment, the crushing component 6 includes a drive motor 61 and a crushing shaft 62. The drive motor 61 is located on one side of the receiving component 2, specifically below the slope 22, making full use of the space below the slope 22 and resulting in a compact design. The crushing component 6 is positioned close to the receiving component 2, allowing coal to directly enter the crushing component 6 after exiting the receiving component 2. Large pieces of coal cannot pass through the crushing component, avoiding blockage of the subsequent conveyor belt. In addition, the exposed crushing component allows for timely intervention in case of malfunction or jamming. For inspection or maintenance; the top anchor bolt assembly 4 consists of three parts, namely the middle top anchor part 41, the first top anchor part 42, and the second top anchor part 43, which simultaneously carry out top anchoring operations, while the two sides are anchored by the first side anchor part 51 and the second side anchor part 52 respectively. The longitudinal sliding rail 511 enables the side anchoring operations to have the freedom to move back and forth, so as to carry out anchoring operations at different positions in front and behind the side without moving the car or with minimal car movement. This allows coal transfer, top anchoring and side anchoring to work together efficiently and reduce the frequency of car movement.

[0045] See Figure 1 , Figure 2 and Figure 5The working principle of the top anchor bolt assembly 4 is as follows: The top anchor bolt assembly 4 includes a central top anchor part 41 and a first top anchor part 42 and a second top anchor part 43 symmetrically arranged on both sides of the central top anchor part 41; wherein, the first top anchor part 42 includes a first transverse telescopic cylinder 421, a second rotary assembly 422, a second swing cylinder 423 and a second drill arm 424, the first transverse telescopic cylinder 421 drives the second drill arm 424 to perform anchoring operations on different parts of one side of the roadway top; the second rotary assembly 422 drives the second drill arm 424 to move outward to the maximum extent. With a rotation angle of 15°, the second rotary assembly 422 drives the second drill arm 424 to rotate inward to a maximum angle of 8°, giving the second drill arm 424 a certain degree of freedom in the left and right directions; the second swing cylinder 423 drives the second drill arm 424 to swing back and forth at an angle of ±6°, giving the second drill arm 424 a certain degree of freedom in the front and back directions; through the first transverse telescopic cylinder 421, the second rotary assembly 422 and the second swing cylinder 423, the transverse position of the second drill arm 424 can be adjusted, and the anchor angle of the second drill arm 424 can also be finely adjusted, making it highly adaptable. The central top anchor 41 includes a third rotating assembly 411, a third swing cylinder 412, and a third drill arm 413. The third rotating assembly 411 drives the third drill arm 413 to swing left and right at an angle of ±8°, and the third swing cylinder 412 drives the third drill arm 413 to swing forward and backward at an angle of ±6°. The third rotating assembly 411 and the third swing cylinder 412 fine-tune the anchor angle of the third drill arm 413. The second top anchor 43 and the first top anchor 42 have the same structure and operating principle, and the specific structure of the second top anchor 43 will not be described in detail. In this embodiment, the central top anchor 41 performs anchoring operations on the middle part of the roadway top. The central top anchor 41 has no lateral movement drive mechanism, while the second top anchor 43 and the first top anchor 42 respectively perform anchoring operations on both sides of the roadway top. The central top anchor 41, the second top anchor 43, and the first top anchor 42 operate independently and are responsible for anchoring operations in different areas of the top, resulting in high collaborative anchoring efficiency.

[0046] See Figure 1 , Figure 2 and Figure 6The working principle of the side anchor bolt assembly 5 is as follows: The vehicle body 1 includes a chassis body 11 and an extension 12 disposed at the rear of the chassis body 11; the side anchor bolt assembly 5 is disposed on both sides of the extension 12; the side anchor bolt assembly 5 includes a first side anchor part 51 and a second side anchor part 52 symmetrically arranged; the first side anchor part 51 includes a longitudinal sliding rail 511, a lifting sliding rail 512, a first rotating assembly 513, a first swing angle cylinder 514, and a first drill arm 515; the longitudinal sliding rail 511 is disposed on the side of the extension 12, the lifting sliding rail 512 moves back and forth along the longitudinal sliding rail 511, the first rotating assembly 513 moves up and down along the lifting sliding rail 512, and the first rotating assembly 513 drives the first drill arm 515 to swing up and down; the first swing angle cylinder 514 drives the first drill arm 515 to swing back and forth. That is, the longitudinal slide rail 511 drives the first drill arm 515 to move back and forth. The length of the longitudinal slide rail 511 is 300mm to 600mm, so that the first drill arm 515 has a degree of freedom of movement of 300mm to 600mm in the front and rear. Even if the vehicle body 1 moves slightly, the first drill arm 515 can still anchor in place, realizing the balance between coal transportation and anchoring. The first slewing assembly 513 drives the first drill arm 515 to rotate at an angle of -15° to 90°. The first drill arm 515 has a swing range of 15° downward and 90° upward, which realizes the adjustment of the angle of the first drill arm 515 and can keep the first drill arm 515 in a vertical state, with a compact structure. The first swing angle cylinder 514 drives the first drill arm 515 to rotate at an angle of ±6°. The first swing angle cylinder 514 drives the first drill arm 515 to swing back and forth to fine adjust the anchoring angle of the first drill arm 515. The structure and operating principle of the second anchor part 52 are the same as those of the first anchor part 51. The specific structure of the second anchor part 52 will not be described in detail.
