After this process is completed, in order to facilitate the robot to stack and store the sawn drill pipe bodies, single-piece feeding needs to be realized. Since the feeding surface and the material blocking surface of the blocking and feeding hook are in a V-shaped connection, the center of gravity of the steel pipe must fall on the feeding surface, and after the steel pipe touches the material dividing inclined surface, the outer surface on its other side should be located outside the trajectory of the material blocking arc surface, so as to successfully realize single-piece feeding.

[0044] Embodiment 1

[0045] Following the above technical solution, as Figures 1 to 6 shown, this embodiment provides a mine drill rod automatic feeding device, including a frame 1, on which a number of buffer racks 2 are spaced and arranged. The buffer racks 2 are inclined, and the lower end of the buffer rack 2 is the feeding end. At the beginning of each feeding end, a drill rod positioning block 3 is provided, and a V-shaped accommodating groove for accommodating the drill rod is formed on the upper surface of the drill rod positioning block 3; on the left and right sides of the buffer rack 2, a stop block adjusting mechanism 4 and a feeding mechanism 5 are respectively provided;

[0046] The stop block adjusting mechanism 4 includes a rotation driving mechanism 41. Specifically, the stop block adjusting mechanism 4 can be a handwheel, a hydraulic / pneumatic motor or an electric motor. A transmission mechanism 42 is provided on the rotation driving mechanism 41; the transmission mechanism 42 includes a first rotating shaft 421, a first connecting rod 422, a second connecting rod 423 and a stop block 424. The lower end of the first connecting rod 422 is connected to the rotation driving mechanism 41. The upper end of the first connecting rod 422 and the lower end of the second connecting rod 423 are respectively sleeved on the first rotating shaft 421, and the first connecting rod 422 and the second connecting rod 423 are respectively key-connected to the first rotating shaft 421. The upper end of the second connecting rod 423 is connected to the stop block 424; the rotation driving mechanism 41 can drive the transmission mechanism 42 to move towards or away from the frame 1, thereby driving the stop block 424 to move back and forth along the length direction of the buffer rack 2.

[0047] When the diameter of the drill rod is larger, the feeding inclined surface of the stop block 424 is close to the drill rod positioning block 3; when the diameter of the drill rod is smaller, the feeding inclined surface of the stop block 424 is farther away from the drill rod positioning block 3.

[0048] The blanking mechanism 5 includes a blanking block 51 connected to the buffer rack 2. The blanking block 51 is also connected to a power mechanism 52 arranged on the frame 1, and the blanking block 51 can swing up and down relative to the frame 1 driven by the power mechanism 52.

[0049] A plurality of block adjusting mechanisms 4 arranged in an array are sleeved on a first rotating shaft 421. The first rotating shaft 421 can drive the plurality of block adjusting mechanisms 4 to move, so that the plurality of blocks 424 move back and forth along the length direction of the buffer rack 2 at the same time, realizing the position adjustment of the drill pipe on the buffer rack.

[0050] As a preferred solution of this embodiment, the power mechanism 52 includes a second rotating shaft 521 horizontally penetrating through the frame 1 along the transverse direction of the frame 1. A third connecting rod 522 is sleeved at a position corresponding to each blanking block 51 on the second rotating shaft 521. One end of the third connecting rod 522 away from the second rotating shaft 521 is connected to the blanking block 51 through a fourth connecting rod 523;

[0051] The power mechanism 52 further includes at least one telescopic cylinder 525 fixedly installed on the frame 1. Specifically, the telescopic cylinder 525 is fixed on the lower column 132, and the power output end of the telescopic cylinder 525 is connected to any one of the third connecting rods 522 through a fifth connecting rod 524. By setting the second rotating shaft 521, it is possible to drive a plurality of blanking blocks 51 to move with one telescopic cylinder 525.

[0052] Preferably, in this embodiment, the third connecting rod 522 is connected to a connecting rod rotating shaft sleeved on the second rotating shaft 521. The connecting rod rotating shaft contains a keyway inside and is key-connected to the second rotating shaft 521. The function of setting the connecting rod rotating shaft is to increase the rigidity of the third connecting rod 522.

[0053] As a preferred solution of this embodiment, the frame 1 at least includes a bottom frame body 11 and a top frame body 12 arranged horizontally, and several columns 13 arranged between the bottom frame body 11 and the top frame body 12. The columns 13 include a first column 131 and a second column 132 oppositely arranged on both sides of the bottom frame body 11, and the height of the first column 131 is greater than that of the second column 132. An intermediate beam 14 is also arranged between the first column 131 and the second column 132;

[0054] A bearing seat 15 is arranged on each intermediate beam 14, and the second rotating shaft 521 passes through the bearing seat 15. The bearing seat 15 is used to provide a rotary support for the second rotating shaft 521.

[0055] As a preferred solution of this embodiment, the rotation drive mechanism 41 includes a drive shaft 411. The output end of the drive shaft 411 is connected to a connecting rod connecting shaft 412. The output end of the connecting rod connecting shaft 412 is connected to a screw rod 414 passing through an installation plate 413. The installation plate 413 is fixedly installed on the lower end surface of the top frame 12.

[0056] On both the left and right sides of the connecting rod connecting shaft 412, there are first connecting shafts 415. The number of the first connecting rods 422 is two, and the lower ends of the two first connecting rods 422 are sleeved on the first connecting shafts 415.

[0057] As a preferred solution of this embodiment, the upper ends of the first connecting rods 422 and the lower ends of the second connecting rods 423 are fixedly connected to a first rotating shaft 421 and can move synchronously with the first rotating shaft 421. A rotating limit block 428 is also sleeved on the first rotating shaft 421. The rotating limit block 428 is fixed on the top frame 3. A through hole is provided on the rotating limit block 428, and the first rotating shaft 421 can rotate in the through hole.

[0058] When the drive shaft 411 rotates clockwise, it drives the connecting rod connecting shaft 412 to approach the installation plate 413, drives the first connecting rods 422 to move counterclockwise, and thus drives the first rotating shaft 421 to rotate in the through hole of the rotating limit block 428. Since the first rotating shaft 421 and the second connecting rod 423 are key-connected, the rotational movement of the first rotating shaft 421 will drive the lower end of the second connecting rod 423 to move away from the top frame 12, thereby driving the stop block 207 to slide along the length direction of the buffer rack 2 towards the drill pipe positioning block 3, so as to realize the position adjustment of the drill pipe on the buffer rack 2.

[0059] As a preferred solution of this embodiment, as Figure 6 shown, the stop block 424 includes a first connecting section 4241, a sliding section 4242, and a second connecting section 4243 which are connected in sequence. A second connecting shaft 425 is passed through the first connecting section 4241, and the second connecting shaft 425 is passed through the second connecting rod 423. A first sliding groove 4244 is formed through the sliding section 4242 along its length direction. In this embodiment, the number of the first sliding grooves 4244 is two. A guiding shaft 426 is passed through each first sliding groove 4244, and the guiding shaft 426 is fixedly connected to the buffer rack 2. The difference between the width of the first sliding groove 4244 and the diameter of the guiding shaft 426 is greater than or equal to 5 mm. A feeding inclined surface is formed on the side of the second connecting section 4243 away from the sliding section 4242. The acute angle formed by the feeding inclined surface and the upper surface of the buffer rack 2 is 60° - 70°, that is, Figure 3 as shown, β is 20° - 30°, so as to facilitate the drill pipe to smoothly roll into the V-shaped accommodating groove of the drill pipe positioning block 3 during feeding.

[0060] A relatively large gap should be set between the first sliding groove 4244 and the guiding shaft 205. Preferably, the width of the first sliding groove 4244 is at least 5 mm larger than the diameter of the guiding shaft. The gap between the first rotating shaft 203 and the through-hole of the rotating shaft limiting block 208 is 5 mm to 10 mm.

[0061] As a preferred solution of this embodiment, a retaining strip 427 is also sleeved on the guiding shaft 426. The retaining strip 427 is arranged on the side of the retaining block 424 away from the buffer rack 2 and is used to limit the retaining block 424 so that it fits against the side wall of the buffer rack 3.

[0062] As a preferred solution of this embodiment, the included angle α between the upper surface of the buffer rack 2 and the horizontal direction is 15° to 25°. Such an angle setting facilitates guiding the drill pipe to roll smoothly and freely to the retaining block 424, and at the same time ensures that the collision sound between the drill pipe 7 and the retaining block 424 is relatively small.

[0063] As a preferred solution of this embodiment, both the fourth connecting rod 523 and the fifth connecting rod 524 are hinged to the third connecting rod 522.

[0064] As a preferred solution of this embodiment, a pumping station 6 is also arranged on the bottom frame 11. The pumping station 6 is connected to the telescopic cylinder 525 and is used to provide power for the telescopic cylinder 525.

[0065] Specifically, in this embodiment, since a number of buffer racks 2 are provided, a number of transmission mechanisms are provided, that is, a plurality of second connecting rods 423, guiding shafts 426, retaining strips 427 and retaining blocks 424 are arranged at equal intervals along the axis direction of the first rotating shaft 421. At this time, the first rotating shaft 421 transmits force to each second connecting rod 423 through a key, thereby driving a plurality of retaining blocks 424 to move back and forth along the buffer rack 2. Similarly, a number of third connecting rods 522, fourth connecting rods 523, fifth connecting rods 524 and material pushing blocks 51 are arranged at equal intervals along the axis direction of the second rotating shaft 521, and the telescopic cylinder 525 can drive a plurality of material pushing blocks 51 to move simultaneously by means of the second rotating shaft 521.

[0066] The axes of the first rotating shaft 421 and the second rotating shaft 521 are arranged in parallel, and the distance between adjacent material pushing blocks 51 is equal to the distance between adjacent retaining blocks 424.

[0067] When this device is in use, the position of the drill pipe on the buffer rack 2 can be adjusted by adjusting the position of the retaining block 207. For example, when the diameter of the drill pipe increases from 50 mm to 89 mm, the adjustment process is as follows:

[0068] First, adjust the position of the drill pipe on the buffer rod 2, specifically including: driving the drive shaft 411 to rotate by means of a power mechanism, the drive shaft 411 driving the connecting rod connecting shaft 412 to approach the mounting plate 413, thereby driving the first connecting rod 422 to move counterclockwise. The first connecting rod 422 drives the first rotating shaft 421 to rotate within the through hole of the rotating shaft limiting block 428. Since the first rotating shaft 421 and the second connecting rod 423 are key-connected, the rotation of the first rotating shaft 421 will drive the lower end of the second connecting rod 423 to move away from the top frame body 12, thereby driving the stopper 207 to slide along the length direction of the buffer frame 2 towards the direction close to the drill pipe positioning block 3, realizing the position adjustment of the drill pipe on the buffer frame 2. After the position adjustment is completed, the drill pipe feeding operation can be carried out. When starting to feed, start the air pump, and the power output end of the telescopic cylinder 525 extends, driving the third connecting rod 522 to move upward. The third connecting rod 522 drives the fourth connecting rod 523 to move counterclockwise along the second rotating shaft 521. At this time, the fourth connecting rod 523 drives the feeding block 51 to swing upward, and feeds the drill pipe to be fed into the V-shaped accommodating groove of the drill pipe positioning block 3, realizing the single-piece sorting of the drill pipe.

[0069] The above implementation process is only an example clearly illustrating the present application, rather than a limitation on the implementation manner. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present application type.
