Fig. 1 is a perspective view of one embodiment of a resin cartridge injection apparatus for a jumbolter according to the present invention.

As can be seen from the embodiment of fig. 1, the resin cartridge injection device comprises a nozzle transfer mechanism 1, a feeding mechanism 2 and an air source control assembly 3, wherein the nozzle transfer mechanism 1 is communicated with the feeding mechanism 2 through a soft nozzle 13, a resin cartridge injection pipeline is formed in the nozzle transfer mechanism 1 and the soft nozzle 13, and the feeding mechanism 2 is communicated with the air source control assembly 3 through a ventilation rubber tube 34.

During the resin cartridge ejection process, the nozzle transfer mechanism 1 is aligned with and extends into the anchor hole to guide the resin cartridge into the anchor hole. The resin cartridge enters an injection pipeline of the injection device from the feeding mechanism 2, and high-pressure air flow emitted by the air source control assembly 3 is used for injecting the resin cartridge in the feeding mechanism 2 through the ventilation rubber pipe 34, and sequentially enters the anchor hole through the soft spray pipe 13 and the spray pipe transfer mechanism 1.

Fig. 2 is a schematic perspective view of one embodiment of a nozzle transfer mechanism of the embodiment of the resin cartridge ejection apparatus of fig. 1. As can be seen from fig. 2, the nozzle transfer mechanism 1 includes a nozzle 11, a hard nozzle 12, a soft nozzle 13, a rotary cylinder 15 and a telescopic cylinder 16, which are sequentially connected.

Specifically, the tail end of the nozzle 11 is inserted into the inner wall of the hard spray pipe 12 in an interference manner, and the nozzle 11 is inserted in an interference manner, so that the nozzle 11 is convenient to install and replace. And the rear end of the nozzle 11 is closely attached to the inner wall of the hard nozzle 12 so that the nozzle 11 is not affected by the high pressure air flow passing through the center of the nozzle 11 during the injection of the resin cartridge.

The inner diameters of the spray head 11, the hard spray pipe 12 and the soft spray pipe 13 are larger than the diameter of the resin cartridge so as to facilitate the passage of the resin cartridge. In an alternative embodiment, the hard nozzle 12 material is polyurethane, which has good stability, chemical resistance, and less compression set, and can contact the resin cartridge without being corroded by the resin cartridge.

According to the embodiment of fig. 2, the spray head 11 is distributed with ventilation holes 14, which ventilation holes 14 allow air to escape. Specifically, during the spraying process, as the resin cartridge enters the anchor hole, air within the anchor hole will be expelled from the vent hole 14 by the extrusion of the resin cartridge, thereby reducing the resistance of the resin cartridge to entry into the anchor hole. In the embodiment of fig. 2, the top end of the sprinkler head 11 is beveled to more conveniently guide the sprinkler head 11 into the anchor hole. In an alternative embodiment, only two-thirds of the top end of the nozzle 11 enters the anchor hole, facilitating the venting of air from the anchor hole through the vent hole 14 during the resin cartridge injection process, thereby facilitating the injection of the resin cartridge into the anchor hole.

As can also be seen from fig. 2, the inner wall of the junction of the hard nozzle 12 and the soft nozzle 13 is provided with a metal connecting sleeve for communicating the hard nozzle 12 with the soft nozzle 13. The outer wall of the joint is fixed by the clamp 8, the clamp has elasticity, and the fixed tightness can be adjusted by bolts so as to accord with the fixed connection between different materials of the hard spray pipe 12 and the soft spray pipe 13, thereby ensuring that the connection between the hard spray pipe 12 and the soft spray pipe 13 is firmer.

As in the embodiment of fig. 2, a hard nozzle guide 5 is provided on the outer wall of the hard nozzle 12 near the spray head 11, the hard nozzle guide 5 being spaced around the outer wall of the hard nozzle 12. A soft nozzle guide body 4 is arranged on the outer wall of the soft nozzle 13 near the joint of the soft nozzle 13 and the hard nozzle 12, and the soft nozzle guide body 4 surrounds the outer wall of the soft nozzle 13 in a clearance way. The rotary oil cylinder 15 and the telescopic oil cylinder 16 are fixedly arranged on the hard spray pipe guide body 5 and the soft spray pipe guide body 4 through the mounting frame body 9, and the spray head 11 is transferred into the anchor hole through rotary expansion when the rotary oil cylinder 15 and the telescopic oil cylinder 16 move to the limit positions.

In the process of spraying the resin cartridge, after the spraying device aligns the spray head 11 with the anchor hole through the rotary oil cylinder 15, the spray head 11 is moved into the anchor hole or partially into the anchor hole through the telescopic oil cylinder 16, and the resin cartridge enters the anchor hole through the spray head 11. During the transfer of the spray head 11, the hard nozzle guide 5 and the soft nozzle guide 4 guide the hard nozzle 12 and the soft nozzle 13 to protrude toward the anchor hole, respectively, so that the spray head 11 enters or partially enters the anchor hole.

In the embodiment of fig. 2, the mounting frame 9 comprises a rotary frame 91 and a guide rail 96, wherein the rotary frame 91 is perpendicular to the hard nozzle 12, specifically, a first end 92 of the rotary frame is fixedly mounted on the hard nozzle guide 5, and a second end 93 of the rotary frame is fixedly mounted on the jumbolter through a mounting seat 94.

The form of the rotary frame 91 is not limited, and as in the embodiment of fig. 2, the rotary frame 91 may be formed by fixedly connecting a link at the second end 93 of the rotary frame to a side surface of a link at the first end 92 of the rotary frame, so as to save installation space, and the rotary frame 91 may be integrally formed. In alternative embodiments, the two connecting rods may be fixedly connected by, but not limited to, welding, bolting, riveting, etc.

According to the embodiment of fig. 2, the rotary cylinder 15 is disposed near the second end 93 of the rotary frame, and the rotary cylinder 15 is fixedly mounted to the jumbolter by a mounting seat 94. The mounting seat 94 is further provided with the rotation limiting block 95, and the rotation limiting block 95 is provided with a limiting hole. The second end 93 of the rotating frame is provided with a bolt which is slidably connected in the limiting hole. When the rotary cylinder 15 drives the rotary frame 91 to rotate, the limiting hole of the limiting block 95 limits the rotation angle of the bolt, so that the first end 92 of the rotary frame drives the hard spray pipe guide 5 to rotate together with the hard spray pipe 12, and the spray head 11 is aligned with the anchor hole.

As can also be seen in fig. 2, the guide rail 96 is parallel to the rigid nozzle 12, a first end 97 of the guide rail is fixedly mounted to the first end 92 of the swivel housing, and a second end 98 of the guide rail is fixedly mounted to the flexible nozzle guide 4. The clamp 8 that the hard spray pipe 12 is connected with the soft spray pipe 13 is connected with the guide rail 96 in a sliding manner, meanwhile, the clamp 8 is fixedly provided with a telescopic part of the telescopic oil cylinder 16, and a fixed part of the telescopic oil cylinder 16 is fixedly provided with the soft spray pipe guide body 4, when the telescopic oil cylinder 16 stretches, the fixed part of the telescopic oil cylinder 16 drives the soft spray pipe 13 and the hard spray pipe 12 to stretch into an anchor hole along the guide rail 96 through the clamp 8, so that the spray head 11 stretches into the anchor hole. The sliding connection between the clip 8 and the guide rail 96 is not limited, as shown in fig. 2, the clip 8 surrounds the guide rail 96 in a gap, so that the clip 8 can more smoothly drive the soft nozzle 13 and the hard nozzle 12 to extend into the anchor hole along the guide rail 96 through the guide of the guide rail 96 in the transferring process, and the spray head 11 is extended into the anchor hole. In other embodiments, the sliding connection may be, but is not limited to, a pulley connection.

The cross-sectional shape of the guide rail 96 is not limited and may be square as in the embodiment of fig. 2, and the square cross-sectional guide rail may accurately provide sliding guidance to make the clip 8 smoother when driving the hard nozzle 12 to slide. In alternative embodiments, the cross-sectional shape of the rail may also be, but is not limited to, circular or flat, etc.

Fig. 3 is a schematic cross-sectional view of a loading mechanism of an embodiment of the resin cartridge ejection apparatus of fig. 1. As can be seen from the embodiment of fig. 3, the feeding mechanism 2 is in communication with the soft nozzle 13 through a quick connector 25, and the quick connector 25 can connect the feeding mechanism 2 with the soft nozzle 13 in a quick plug-and-play manner before or after the nozzle 11 enters the anchor hole, so that the alignment of the nozzle 11 and the rotation and stretching operation into the anchor hole do not affect the connection between the soft nozzle 13 and the feeding mechanism 2.

Specifically, the loading bin 21 of the loading mechanism 2 is provided with an air inlet 23, and a high-pressure air flow can be input from the air inlet 23. The upper bin 21 may have a through passage. In other embodiments, the upper bin 22 is further provided with a spare port (not shown) for cleaning residual resin cartridges in the soft nozzle 13 and the hard nozzle 12 through water.

According to the embodiment of fig. 3, the loading mechanism 2 comprises a loading opening 21 and a loading bin 22, a ball valve 24 being arranged between the loading bin 22 and the loading opening 21. When the switch valve 32 is not opened by an electric signal and resin cartridges are put in, the ball valve 24 is opened by rotating the handle, the resin cartridges 7 are manually put in the through channels in the upper storage bin 22 from the opening of the ball valve 24, the resin cartridges 7 sequentially pass through the opening of the ball valve 24 and the upper storage bin 22 from the feeding hole 21 to enter the soft spray pipe 13, then the ball valve 24 is closed to seal the upper storage bin 22, a sealed space is formed in the upper storage bin 22, high-pressure air flows enter the sealed upper storage bin 22 through the air inlet 23, and the resin cartridges in the soft spray pipe 13 are sprayed.

The ball valve 24 has good sealing performance, can conveniently open or close the feeding bin 22 through a handle, and is simple and reliable in arrangement, and suitable for underground coal mine environments. In alternative embodiments, the ball valve 24 may also be a solenoid valve, and the opening and closing of the ball valve 24 may be controlled by an electrical signal. In other embodiments, the upper bin 22 may also be opened and closed by, but not limited to, a sealing valve or the like.
