The wet dust collector 006 is arranged at the top of the frame 001 and is positioned behind the working platform 0010, and the wet dust collector 006 can dust fall on the working face, so that the working face is ensured to have a better working environment.

The scraper chain compensation device 004 is arranged at the scraper conveying device 005, the scraper conveying device 005 at least comprises two sections, the scraper chain of the scraper conveying device 005 can loosen during swinging, and the scraper chain compensation device 004 can automatically tension the loosened scraper chain, so that the stable operation of the scraper conveying device 005 is ensured.

The drill mount 200 includes a first plate 210, a second plate 220, and a third plate 230, the first plate 210 and the second plate 220 being disposed opposite to each other in a first direction, the third plate 230 being connected between the first plate 210 and the second plate 220 in the first direction; the jumbolter 300 is rotatably arranged on the drill mounting seat 200, and the rotation axis of the jumbolter 300 extends along a first horizontal direction; the linear drive assembly 100 is coupled to the drill mount 200 to drive the drill mount 200 and the jumbolter 300 to move in a second horizontal direction, the first horizontal direction being perpendicular to the second horizontal direction.

The jumbolter 300 is rotatably mounted to the drill mount 200 with the axis of rotation of the jumbolter 300 extending in a first horizontal direction (e.g., the front-to-back direction in fig. 2). That is, the jumbolter 300 is mounted on the drill mount 200, and the jumbolter 300 is rotatable about an axis of rotation relative to the drill mount 200.

The linear drive assembly 100 is coupled to the drill mount 200 to drive the drill mount 200 and the jumbolter 300 in a second horizontal direction (e.g., left-right in fig. 2), the first horizontal direction being perpendicular to the second horizontal direction.

The jumbolter 300 according to the embodiment of the present invention can move in the second horizontal direction under the driving of the linear driving assembly 100, so that the range of support of the jumbolter 300 to the top of the roadway in the second horizontal direction is large.

Therefore, the jumbolter 300 provided by the embodiment of the invention can support the top of the roadway in a large range, so that the stability of the roadway is improved, and the safety of a coal mine is facilitated.

In some embodiments, as shown in fig. 2-4, the linear drive assembly 100 includes a stationary base 110, a movable base 130, and a first telescopic member 120.

The moving seat 130 is disposed on the drill mounting seat 200, and the moving seat 130 is reciprocally disposed on the fixed seat 110 along the second horizontal direction. That is, the drill mount 200 and the movable base 130 can only reciprocate left and right with respect to the fixed base 110.

The first telescopic device 120 is connected with the fixed seat 110, and the first telescopic device 120 is also connected with the movable seat 130 to drive the movable seat 130, the drilling machine installation seat 200 and the jumbolter 300 to move along the second horizontal direction. That is, the roof bolter 300 is moved left and right by the driving of the first telescopic device 120, and thus the roof bolter of the embodiment of the present invention can support the roof of the roadway in a wide range.

In some embodiments, as shown in fig. 2-4, the fixed seat 110 and the movable seat 130 are opposite in a first horizontal direction, and the first telescopic device 120 is located between the fixed seat 110 and the movable seat 130 along the first horizontal direction.

As shown in fig. 2 and 3, the fixed base 110 has two first sliding grooves 112 opposite to each other up and down, and the movable base 130 has two sliding plates 132 opposite to each other up and down, and the two sliding plates 132 are engaged with the two first sliding grooves 112, respectively. Specifically, the notch of one first runner 112 is downward and the notch of the other slide 132 is upward. That is, at least part of the moving seat 130 is located between the two first sliding grooves 112 in the up-down direction. Further, the first telescopic device 120 is located between the fixed base 110 and the movable base 130 in the front-rear direction. Therefore, the linear driving assembly 100 has a small size in the front-rear direction, is compact, and saves space.

In some embodiments, as shown in fig. 2, the first telescopic device 120 includes a first body 121 and a first telescopic member 122, and the first telescopic member 122 is reciprocally movably provided on the second body 411 along a length direction of the first body 121. The first body 121 is hinged with the fixed seat 110, and the first telescopic member 122 is hinged with the movable seat 130 so as to drive the movable seat 130, the drill mounting seat 200 and the jumbolter 300 to move in the second horizontal direction.

In some embodiments, as shown in fig. 2 and 4, the linear drive assembly 100 includes a first ear mount 111, a second ear mount 131, and a telescoping chamber.

As shown in fig. 2, the first ear mount 111 is disposed at one end of the fixing base 110 in the length direction (e.g. the left end of the fixing base 110 in fig. 2), the first body 121 is hinged to the first ear mount 111, and the length direction of the fixing base 110 (e.g. the left-right direction in fig. 2) is parallel to the second horizontal direction. The fixing base 110 has a first groove 113. The first groove 113 is located at one side of the thickness direction of the fixing base 110 (e.g., the front side of the fixing base 110 in fig. 2), and the thickness direction of the fixing base 110 (e.g., the front-rear direction in fig. 2) is parallel to the first horizontal direction. That is, the opening of the first groove 113 is directed forward. Specifically, the first groove 113 is located between the two first sliding grooves 112 of the fixing base 110 in the up-down direction.

As shown in fig. 4, the second ear mount 131 is disposed at one end of the moving mount 130 in the length direction (e.g., the right end of the moving mount 130 in fig. 4), the first telescopic member 122 is hinged to the second ear mount 131, and the length direction (e.g., the left-right direction in fig. 2) of the moving mount 130 is parallel to the second horizontal direction. The movable seat 130 has a second recess 133. The second groove 133 is located at one side of the thickness direction of the movable base 130 (e.g., the rear end of the movable base 130 in fig. 4), and the thickness direction of the movable base 130 (e.g., the front-rear direction in fig. 4) is parallel to the first horizontal direction. That is, the opening of the second groove 133 faces rearward. Specifically, the second groove 133 is located between the two sliding plates 132 of the moving seat 130 in the up-down direction.

That is, as shown in fig. 2 and 4, the first ear mount 111 and the second ear mount 131 are opposed left and right. The first groove 113 and the second groove 133 are opposite in the front-rear direction, and a bellows is formed between the first groove 113 and the second groove 133. At least a portion of the first telescoping member 122 is located within the telescoping lumen.

As shown in fig. 4, a positioning block 134 is disposed in the second groove 133, and one side of the positioning block 134 adjacent to the fixing base 110 in the front-rear direction has an arc surface. That is, the rear side of the positioning block 134 is an arc surface. The arc surface of the positioning block 134 can be attached to the outer peripheral surface of the first body 121 of the first telescopic device 120, the positioning block 134 can play a limiting role on the first body 121, and can prevent the first body 121 and thus the first telescopic device 120 from swinging in the front-back direction or the up-down direction, so that the length direction of the first body 121 is parallel to the left-right direction, and further, the moving seat 130 is guaranteed to move in the left-right direction relative to the fixed seat 110. Therefore, the linear driving assembly 100 can smoothly and stably operate.

According to the tunneling and anchoring integrated machine of the embodiment of the invention, the sliding plate 132 of the movable seat 130 is engaged with the first sliding slot 112 of the fixed seat 110, that is, at least a part of the movable seat 130 is located in the fixed seat 110. In other words, when the fixed seat 110 and the movable seat 130 are fitted together, the dimensions of the fixed seat 110 and the movable seat 130 in the front-rear direction are smaller than the sum of the dimensions of the fixed seat 110 and the movable seat 130 in the front-rear direction. The linear driving assembly 100 is small in size in the front-rear direction. In addition, the first telescopic member 122 drives the movable seat 130 to move left and right relative to the fixed seat 110 in the telescopic cavity, and when the first telescopic member 122, the fixed seat 110 and the movable seat 130 are matched together, the first telescopic member 122 does not occupy additional space, and the size of the linear driving assembly 100 in the front-rear direction is kept unchanged.

In some embodiments, as shown in fig. 1, 3-6, the bolter 300 includes a first bolter 310 and a second bolter 320. The first and second jumbolters 310 and 320 are oppositely disposed in the left-right direction. That is, the first and second jumbolters 310 and 320 are rotatably mounted on the rig floor 200, with the first jumbolter 310 being located to the left of the second jumbolter 320, or, in other words, the second jumbolter 320 being located to the right of the first jumbolter 310. The rotational axis of the first bolter 310 is parallel to the rotational axis of the second bolter 320, and both the rotational axis of the first bolter 310 and the rotational axis of the second bolter 320 extend in the fore-aft direction.

Here, the roof bolter according to the embodiment of the present invention is mounted on a frame of the all-in-one machine and is located at one side of the cutting device 002 of the all-in-one machine in the left-right direction. That is, the jumbolter 300 of the present embodiment is located on the left or right side of the all-in-one machine. The cutting device 002 may prevent the jumbolter 300, which is adjacent to the cutting device 002 in the left-right direction, from rotating to a side adjacent to the cutting device 002.
