Description

Technical Field

[0001] The utility model relates to the technical field of shotcrete machines, in particular to a remote shotcrete machine with adjustable quantity. Background Art

[0002] Remote shotcrete machine is an efficient and reliable equipment, mainly used for shotcrete operations in underground projects such as mines and tunnels. It drives the hydraulic pump to rotate through the motor, delivers pressurized oil to the shotcrete gun, drives the piston to pressurize the slurry stored in the slurry storage barrel to the nozzle, and sprays the slurry onto the working surface through the atomization effect of the nozzle.

[0003] Remote shotcrete machines can work in harsh environments, have strong adaptability and good stability, have undergone full explosion-proof treatment, and are equipped with a coal safety certificate for the entire machine, thus ensuring the safety of miners' lives. However, in the existing technology, most remote shotcrete machines are unable to control the amount of shotcrete, resulting in the inability to spray the required amount during construction, low work efficiency, and insufficient practicality. Therefore, it is necessary to redesign an adjustable remote shotcrete machine to address the above problems. Utility Model Content

[0013] 1. By setting up components such as a tooth plate, a rotating rod, a gear and an intercepting plate, the tooth plate can be driven to move back and forth under the telescopic action of the electric push rod. When the tooth plate moves, it can engage with the gear. When the gear and the tooth plate engage with each other, the gear can be driven to rotate. When the gear rotates, the rotating rod can be driven to rotate. When the rotating rod rotates, the intercepting plate on its outer wall can be turned over, thereby realizing the spraying of different required amounts of mortar.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-6 The jacks 2 are fixedly mounted on the bottom wall of the base 1, and each of the jacks 2 is a universal wheel. The universal wheel is a movable caster. Its structural design allows it to rotate 360 ​​degrees on the horizontal plane, and can be easily moved in any direction, greatly improving the efficiency of carrying and moving objects. The upper end surface of the base 1 is rotatably mounted with a screw 4 through a fixed frame 3. The outer wall of the fixed frame 3 is fixedly mounted with a first motor 5 connected with the screw 4. The outer wall of the screw 4 is threadedly mounted with a movable sleeve 7 through a limiting mechanism. The limiting mechanism includes a limiting rod 6 fixedly mounted on the inner wall of the fixed frame 3, and the limiting rod 6 slides through the movable sleeve 7. The limiting rod 6 can limit the movable sleeve 7 so that the movable sleeve 7 can only move axially along the outer wall of the screw 4. The upper end surface of the movable sleeve 7 is fixedly mounted with a connecting sleeve 9 through a lifting mechanism. The lifting mechanism includes a cylinder 8 fixedly mounted on the upper end surface of the movable sleeve 7. The telescopic end of the cylinder 8 is fixedly connected to the outer wall of the connecting sleeve 9, and a spraying channel 10 is fixedly mounted on the inner wall of the connecting sleeve 9.

[0024] The spraying channel 10 is internally rotatably installed with multiple auger blades 11, the outer wall of the spraying channel 10 is fixedly installed with a second motor 12 connected to the rotating shaft of the auger blade 11, the end of the spraying channel 10 is fixedly installed with a nozzle 13, the outer wall of the spraying channel 10 is fixedly installed with a feed hopper 14 through the installation opening, the inner wall of the feed hopper 14 is slidably installed with a filter plate 16 through a fixing mechanism, the fixing mechanism includes a fixed block 15 fixedly installed on the outer wall of the feed hopper 14 on both sides, the filter plate 16 is slidably installed on the upper end surface of the two fixed blocks 15, and the spraying A support plate 17 is fixedly installed on the outer wall of the channel 10, and a mounting plate 19 is fixedly installed on the inner wall of the support plate 17 through a telescopic mechanism. The telescopic mechanism includes an electric push rod 18 fixedly installed on the inner wall of the support plate 17, and the telescopic end of the electric push rod 18 is fixedly connected to the outer wall of the mounting plate 19. A tooth plate 20 is fixedly installed on the inner wall of the mounting plate 19. A rotating rod 21 is rotatably installed on the outer wall of the nozzle 13, and a gear 22 is fixedly installed on the end of the rotating rod 21. The gear 22 and the tooth plate 20 are engaged with each other, and an intercepting plate 23 is fixedly installed on the outer wall of the rotating rod 21.

[0025] The filter plate 16 can filter the larger sand and gravel in the mortar to prevent the sand and gravel from being blocked during the spraying of the spraying machine. The larger sand and gravel after filtering can be collected and recycled, and the filtered mortar can fall into the inside of the spraying channel 10 through the discharge port in the feed hopper 14. At this time, the second motor 12 drives the auger blade 11 to rotate, and the rotating auger blade 11 can drive the mortar to flow out of the nozzle 13. When the required mortar amount is different, the tooth plate 20 can be driven back and forth by the telescopic action of the electric push rod 18. When the tooth plate 20 moves, it can drive the gear 22 that meshes with each other to rotate. When the gear 22 and the tooth plate 20 mesh, it can drive the rotating rod 21 to rotate. When the rotating rod 21 rotates, it can drive the intercepting plate 23 on the inner wall of the nozzle 13 to flip. Therefore, the amplitude of the intercepting plate 23 can be flipped according to the required mortar amount, so that different required amounts of mortar can be sprayed.

[0026] At the same time, when it is necessary to adjust the spraying distance of the spraying machine, the first motor 5 can drive the screw 4 to rotate. When the screw 4 rotates, it can drive the movable sleeve 7 to move by cooperating with the limit rod 6. When the movable sleeve 7 moves, it can drive the spraying channel 10 on the inner wall of the connecting sleeve 9 to move left and right by cooperating with the cylinder 8, thereby realizing spraying construction on construction surfaces at different distances. Under the telescopic action of the cylinder 8, the spraying channel 10 can be driven to move up and down, thereby realizing spraying construction on construction surfaces at different heights.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
