[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] The purpose of this invention is to provide an automatic mesh feeding device based on a bolt drilling rig, so as to solve the problems existing in the prior art and improve the efficiency of mesh laying during the support operation by the bolt drilling machine.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-5 As shown, this embodiment provides an automatic net feeding device based on a bolt drilling rig, including a frame 1, a net storage bin, a net suction cup, and two lifting and tilting mechanisms.

[0033] The frame 1 is fixedly connected to the body of the anchor drilling rig, allowing the frame 1 to move with the movement of the anchor drilling rig's body. The mesh storage compartment is used to store the mesh, and includes a fixed mesh storage compartment 31. The fixed mesh storage compartment 31 includes a horizontal plate and a vertical baffle. One end of the horizontal plate is fixedly connected to the frame 1, and the bottom end of the vertical baffle is fixedly connected to the other end of the horizontal plate.

[0034] In the embodiment, the screen bin further comprises a left side moving screen bin 33 and a right side moving screen bin 32 which are respectively in sliding fit with the fixed screen bin 31. The left side moving screen bin 33 and the right side moving screen bin 32 both comprise a side moving bottom plate 331 and a side moving baffle 332 which is fixedly connected with one end of the side moving bottom plate 331. The side moving bottom plate 331 is in sliding fit with the horizontal plate, and the side moving baffle 332 is close to the vertical baffle. The fixed screen bin 31, the left side moving screen bin 33 and the right side moving screen bin 32 are all in L shape. The left side moving screen bin 33 and the right side moving screen bin 32 are arranged to be retracted into the fixed screen bin 31, so as to reduce the size of the whole screen bin, which is beneficial to the automatic screen feeding device to pass through the narrow roadway of the coal mine.

[0035] A sliding groove 301 is arranged on the side moving bottom plate 331, and the length direction of the sliding groove 301 is perpendicular to the length direction of the slide rail 24. A pin shaft 38 is arranged on the horizontal plate corresponding to any one of the sliding grooves 301. The pin shaft 38 penetrates through the corresponding sliding groove 301, and a gland is fixedly arranged on the top end of the pin shaft 38. The diameter of the gland is greater than the width of the sliding groove 301. The sliding groove 301 is in sliding fit with the corresponding pin shaft 38. The bottom end of the pin shaft 38 is fixedly connected with the side moving bottom plate 331 through a nut, but the side moving bottom plate 331 can be manually driven to slide on the horizontal plate after the nut is fastened. It should be noted that the gland has a limiting effect on the side moving bottom plate 331, which can prevent the side moving bottom plate 331 from tilting under the action of its own gravity and the gravity of the side moving baffle 332 after the side moving bottom plate 331 slides.

[0036] The left side moving screen bin 33 and the right side moving screen bin 32 both comprise a plurality of limiting rods 302 which are distributed along the length direction of the slide rail 24. The bottom end of the limiting rod 302 is fixedly connected with the side moving bottom plate 331. The interval between the limiting rod 302 closest to the side moving baffle 332 and the side moving baffle 332 and the interval between any two adjacent limiting rods 302 are both greater than or equal to the thickness of the screen to be used. In the embodiment, the limiting rods 302 are arranged because the screen is usually a screen formed by welding a plurality of horizontal and vertical steel bars, which has poor rigidity and cannot stand on the side. The limiting rods 302 are welded on the right side moving screen bin 32 and the left side moving screen bin 33. The interval between the two limiting rods 302 or the interval between the limiting rod 302 closest to the side moving baffle 332 and the side moving baffle 332 can meet the requirement that the screen can stand and slide up and down. In actual application, the number of the limiting rods 302 can be adaptively selected according to actual needs. In addition, the plurality of limiting rods 302 which are distributed along the length direction of the slide rail 24 form a row of limiting rods 302. In actual application, in order to improve the stability of the screen standing in the screen bin, two rows or even more rows of limiting rods 302 which are parallel to each other can be arranged on the same side moving bottom plate 331.

[0037] The mesh suction cup is used for sucking the mesh in the mesh bin, and a permanent magnet 3605 is arranged on the mesh suction cup;

[0038] In the embodiment, the mesh suction cup includes a fixed mesh suction cup 36 and two side moving mesh suction cups 37. The hinged seat 30 is fixedly connected with the fixed mesh suction cup 36. The two side moving mesh suction cups 37 are respectively in sliding fit with the fixed mesh suction cup 36. A third driving device 3606 is arranged on the fixed mesh suction cup 36 corresponding to each side moving mesh suction cup 37, and the third driving device 3606 is used for driving the corresponding side moving mesh suction cup 37 to slide relative to the fixed mesh suction cup 36. The two side moving mesh suction cups 37 can be respectively located on the two sides of the fixed mesh suction cup 36. The permanent magnets 3605 are respectively arranged on the two side moving mesh suction cups 37. In the embodiment, the third driving device 3606 is a hydraulic oil cylinder.

[0039] The fixed mesh suction cup 36 is provided with an upper sliding rail and a lower sliding rail corresponding to each side moving mesh suction cup 37. Specifically, the two upper sliding rails are a first upper sliding rail 3601 and a second upper sliding rail 3602, and the two lower sliding rails are a first lower sliding rail 3603 and a second lower sliding rail 3604. One side moving mesh suction cup 37 is in sliding fit with the first upper sliding rail 3601 and the first lower sliding rail 3603, and the other side moving mesh suction cup 37 is in sliding fit with the second upper sliding rail 3602 and the second lower sliding rail 3604. The third driving device 3606 is used for driving the side moving mesh suction cup 37 to slide outward, so as to adjust the position of the side moving mesh suction cup 37 for sucking the mesh. Since the mesh is often long, the position of the side moving mesh suction cup 37 for sucking the mesh is preferably as far as possible to the outside, so as to improve the stability of the mesh.

[0040] The two lifting and overturning mechanisms are parallel and spaced apart. Each lifting and overturning mechanism includes a sliding rail 24, a sliding seat 25, a lower sleeve 39, an upper sleeve 26, a first connecting rod 28, a second connecting rod 29, and a hinged seat 30.

[0041] In the embodiment, the fourth driving device 27 is a rotary oil cylinder, the other end of the first connecting rod 28 is fixedly connected with the output shaft of the rotary oil cylinder, and the rotary oil cylinder can drive the first connecting rod 28 to rotate around the output shaft of the rotary oil cylinder when the rotary oil cylinder works.

[0042] It should be noted that, in actual application, the fourth driving device 27 (the fourth driving device 27 is a rotary oil cylinder) can also be used to drive the second connecting rod 29 to rotate, at this time, the end of the second connecting rod 29 away from the hinged seat 30 is fixedly connected with the output shaft of the rotary oil cylinder, and the end of the first connecting rod 28 is hinged with one end of the hinged seat 30, and the other end of the first connecting rod 28 is hinged with the top end of the upper sleeve 26; in addition, in actual application, other forms of driving devices and transmission mechanisms can also be used to drive the first connecting rod 28 or the second connecting rod 29 to rotate, as long as the net suction cup can be finally turned over.

[0043] In the embodiment, the second driving device is a hydraulic oil cylinder. The slide rail 24 is provided with a rack 35, the length direction of the rack 35 is the same as the length direction of the slide rail 24, the first driving device 34 is a driving motor fixedly arranged on the slide 25, and a driving gear engaged with the rack 35 is fixedly arranged on the output shaft of the first driving device 34.

[0045] The working process of the automatic net feeding device based on the anchor rod drill carriage in the embodiment is as follows:

[0046] The anchor rod drill carriage provided with the automatic net feeding device based on the anchor rod drill carriage in the embodiment is driven to the middle position of the roadway, the right side net moving bin 32 and the left side net moving bin 33 are manually pulled out (i.e. the right side net moving bin 32 and the left side net moving bin 33 are respectively moved to the two sides of the fixed net bin 31), and the net is vertically placed between the two limiting rods 302 or between the limiting rod 302 closest to the side moving baffle 332 and the side moving baffle 332.

[0047] The side shifting screen suction disc 37 is driven to extend by the third driving device 3606, the slide base 25 is driven to slide along the slide rail 24 towards the screen bin by the first driving device 34, the slide base 25 drives the lower sleeve 39, the upper sleeve 26, the first connecting rod 28, the second connecting rod 29, the hinged seat 30 and the screen suction disc to slide when sliding, until the screen suction disc slides to the screen bin, after the screen suction disc contacts the screen, the first driving device 34 continues to drive the screen suction disc to press the screen, after the pressure of the driving motor, i.e. the first driving device 34, reaches a set value, the driving motor is stopped, so that the screen suction disc no longer slides.

[0048] Then the second driving device in the lower sleeve 39 lifts the upper sleeve 26 to make the bottom end of the screen higher than the top end of the screen bin, then the rotary oil cylinder drives the first connecting rod 28 to rotate, so that the screen is reversed from the vertical state to the horizontal state, the first driving device 34 drives the slide base 25 to slide along the slide rail 24 away from the screen bin, until the end of the slide rail 24 away from the screen bin, and the slide base 25 triggers the first electromagnetic proximity switch, then the screen is dragged to the top of the drilling rig by the supporting worker on the rack 1, and the screen feeding process is completed.
