Description

Technical Field

[0001] This invention belongs to the field of drilling and mining technology, specifically relating to a drilling and mining device for thin coal seams. Background Technology

[0002] The invention patent with publication number CN114151077A discloses a method and apparatus for drilling and mining thin coal seams. The apparatus includes a housing, a fixed frame mounted on the upper end of the housing, a disc mounted on the fixed frame, and a mounting groove adapted to the disc on the surface of the fixed frame. The disc is fixedly installed in the mounting groove. A motor is mounted on the end of the disc, and the output shaft of the motor passes through the disc and is located at the center of the disc. A connecting rod is fixedly connected to the output shaft, and a support frame is fixedly connected to the other end of the connecting rod. A driving component is mounted on the support frame, and a crushing blade is rotatably mounted inside the support frame. Wheels are mounted on the bottom end of the housing, and a receiving cavity is formed on the surface of the housing. The housing is provided with a collection structure for collecting coal and an adjustment structure for adjusting the crushing blade.

[0003] In summary, this invention patent includes an upper drill bit assembly and a lower coal collection structure. This top-and-bottom structure has the following disadvantages: because the shape of the pit wall in a coal mine pit is not a flat vertical surface, but an irregular surface with unevenness, there is a situation where the lower part of the pit wall is more convex than the upper part. This causes the lower collection structure to abut against the pit wall first, forming a forward limit, which prevents the upper drill bit assembly from contacting the pit wall, resulting in a situation where drilling cannot occur. Summary of the Invention

[0004] In view of the problems raised in the background art above, the purpose of the present invention is to provide a thin coal seam drilling and mining device.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A thin coal seam drilling and mining device includes a drill bit assembly, a collection mechanism, and a body. The drill bit is located directly above the collection mechanism, which includes...

[0007] The guide unit is provided with two rows of parallel guide rods and an end plate that connects the two rows of guide rods.

[0008] The rotating seat is passed through the guide rod and fixed to the guide rod by a locking structure. The rotating seat is located at one end near the end plate. There are two rotating seats in total, corresponding one-to-one with the two columns of guide rods.

[0009] The bracket is fixedly connected to the machine body at the bottom and hinged to the rotating seat at the top. There are two brackets, each corresponding to one of the two rotating seats.

[0010] A fixing seat is passed through and fixedly connected to the guide rod. The fixing seat is located at the end away from the end plate. There are two fixing seats, which correspond one-to-one with the two columns of guide rods.

[0011] A support plate, fixedly connected to two rotating seats and located between the two rotating seats; and

[0012] The coal guide plate is fixedly connected to two fixed seats on one side and located between the two fixed seats, while the other side overlaps the upper surface of the bearing plate.

[0013] Furthermore, the machine body is equipped with a storage chamber for storing coal. This structural design allows for the storage of large quantities of coal collected by the collection mechanism.

[0014] Furthermore, the guide rod has a beveled surface at the end furthest from the end plate. This structural design increases the contact area between the guide rod and the coal pit wall, thereby improving the placement stability of the guide unit.

[0015] Furthermore, the end plate is provided with a handrail on the side opposite to the guide rod for swinging up and down. This structural design makes it convenient for staff to adjust the angle of the guide unit up and down using the handrail.

[0016] Further specifying, the rotating seat has an L-shaped part, a hinge ring located on the bottom side of the L-shaped part, and a first slip ring located on the vertical side of the L-shaped part. The diameter of the first slip ring is adapted to the diameter of the guide rod. With this structural design, the first slip ring is mainly used for sliding connection with the guide rod, the hinge ring is mainly used for hinge connection with the bracket, and the L-shaped part serves as a connection while also cooperating with the bearing plate.

[0017] Furthermore, the support plate has a side that fits against the vertical edge of the L-shaped part, and the support plate and the L-shaped part of the rotating seat are fixed by bolt connection. With this structural design, the side of the support plate is mainly used to fit against the vertical edge of the L-shaped part, so that the connection can fit tightly.

[0018] Further defining the fixed base, it is provided with a second slip ring and a vertical plate located outside the second slip ring. The two fixed bases are arranged opposite each other with respect to the vertical plate. In this structural design, the second slip ring is mainly used to slide and cooperate with the two guide rods, and the vertical plate is mainly used to fit against the coal guide plate.

[0019] Further specified, the coal guide plate is provided with a semi-circular cross-section pocket plate and corner supports located at the two warped ends of the pocket plate. The coal guide plate is fixed to the fixed seat by bolt connection. The corner supports are attached to the vertical plate. In this structural design, the arc-shaped pocket plate mainly plays a converging role, which facilitates the transportation of coal resources. The corner supports are used to attach to the vertical plate on the fixed seat.

[0020] Further defining the locking structure, the locking structure includes an outer locking hole on the rotating seat, inner locking holes distributed along the axial direction of the guide rod, and a locking pin for engagement. This structural design allows the guide rod and the rotating seat to be fixed in relative positions by inserting the locking pin into the outer locking hole and then into the inner locking hole. When the locking pin is removed, the guide rod can slide along the rotating seat. The outer locking hole engages with different inner locking holes, and the guide rod and the rotating seat can be locked in different relative positions by the locking pin.

[0021] The beneficial effects of this invention are:

[0022] 1. When the collecting mechanism comes into contact with the pit wall in front of the drill bit assembly, the locking structure is released, allowing the guide unit where the guide rod is located to slide back and forth along the rotating seat. The coal miner pulls the guide unit backward, causing the fixed seat and the coal guide plate to move backward together, thereby creating a forward movement distance between the drill bit assembly and the pit wall.

[0023] 2. In order to bring the collecting mechanism closer to the coal mining point and prevent the falling coal resources from scattering, the coal miners can press down the end plate of the guide unit, so that the other end of the guide unit is raised and pressed against the pit wall to fix its own posture, thus approaching the coal mining point in an inclined posture. The inclined posture also helps the material to fall. Attached Figure Description

[0039] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] like Figure 1-7 As shown, the thin coal seam drilling and mining device of the present invention includes a drill bit assembly, a collection mechanism, and a body. The drill bit is located directly above the collection mechanism, which includes...

[0041] The guide unit 1 is provided with two rows of parallel guide rods 11 and an end plate 12 that connects the two rows of guide rods 11.

[0042] Rotary seat 2 is passed through by guide rod 11 and fixed to guide rod 11 by locking structure. Rotary seat 2 is located at one end near end plate 12. There are two rotating seats 2, which correspond one-to-one with the two rows of guide rods 11.

[0043] The bracket is fixedly connected to the machine body at the bottom and hinged to the rotating seat 2 at the top. There are two brackets in total, each corresponding to one of the two rotating seats 2.

[0048] When the collecting mechanism comes into contact with the pit wall before the drill bit assembly, the locking structure is released, allowing the guide unit 1 where the guide rod 11 is located to slide back and forth along the rotating seat 2. The coal miner pulls the guide unit 1 backward, causing the fixed seat 3 and the coal guide plate 4 to move backward together, thereby forming a forward movement gap between the drill bit assembly and the pit wall. The bearing plate 5 is located at the bottom of the coal guide plate 4 and is used to bear the weight of the coal guide plate 4, avoiding the load being concentrated at the fixed point of the coal guide plate 4 and the fixed seat 3.

[0049] In order to bring the collecting mechanism closer to the coal mining point and prevent the falling coal resources from scattering, the coal miners can press down the end plate 12 of the guide unit 1, so that the other end of the guide unit 1 is raised and pressed against the pit wall to fix its own posture, thereby approaching the coal mining point in an inclined posture. The inclined posture also helps the material to fall.

[0050] Preferably, the machine body is equipped with a storage chamber for storing coal. This structural design allows for the storage of large quantities of coal collected by the collection mechanism. In practice, other coal storage structures can also be considered depending on the specific circumstances.

[0051] Preferably, the guide rod 11 has a beveled surface 112 at the end away from the end plate 12.

In practice, other structural shapes that increase the placement stability of the guide unit 1 can also be considered depending on the specific circumstances.

[0052] Preferably, the end plate 12 has a handrail on the side opposite to the guide rod 11 for vertical swinging.

[0054] Preferably, the support plate 5 has a side that fits against the vertical edge of the L-shaped portion 21. The support plate 5 and the L-shaped portion 21 of the rotating seat 2 are fixed together by bolts. With this structural design, the side of the support plate 5 is mainly used to fit against the vertical edge of the L-shaped portion 21, so that the connection can fit tightly.

In fact, other structural shapes of the fixed base 3 can also be considered according to specific circumstances.

[0056] Preferably, the coal guide plate 4 is provided with a semi-circular cross-section pocket plate 41 and corner supports 42 located at the two curved ends of the pocket plate 41. The coal guide plate 4 is fixed to the fixed seat 3 by bolt connection. The corner supports 42 are attached to the vertical plate 31. In this structural design, the arc-shaped pocket plate 41 mainly plays a converging role, which facilitates the transportation of coal resources, and the corner supports 42 are used to attach to the vertical plate 31 on the fixed seat 3. In fact, other structural shapes of the coal guide plate 4 can also be considered according to specific circumstances.

[0057] Preferably, the locking structure includes an outer locking hole on the rotating seat 2, inner locking holes 111 distributed along the axial direction of the guide rod 11, and a locking pin 6 for engagement.
