Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete construction equipment, in particular to a concrete spraying machine with angle adjustment. BACKGROUND

[0002] The concrete spraying machine refers to a mechanical device that uses compressed air to form a suspended state airflow of concrete with a certain proportion and sprays it to the surface to be coated to form a dense concrete layer to achieve the purpose of support.

[0003] The publication number CN213774529U discloses a concrete spraying machine with convenient adjustment of spraying range, which is characterized in that the inner wall of the tank body is in close contact with the lower end of the stirring rod, and the upper end of the stirring rod and the upper end of the middle part of the tank body form a rotating structure, so that the concrete can be stirred to avoid adhesion during transportation, resulting in uneven discharge. The spraying barrel and the supporting rod form a rotating structure and are correspondingly arranged with the supporting rod, which can make the spraying barrel more stable. The first adjusting rod and the sleeve rod are connected by threads, and the block forms a sliding structure at the lower end of the middle part of the spraying barrel, which can make the spraying barrel produce angular inclination of up and down movement while the first adjusting rod rotates. The left end of the transmission wheel is connected with the right end of the gear strip in a meshing manner, which can drive the transmission wheel to rotate while the gear strip moves forward and backward, so as to make the spraying barrel produce angular rotation left and right, which is convenient for adjusting the spraying range and effectively improves the spraying efficiency of the device. However, the patent still has the following problems in actual use:

[0004] Although the concrete spraying machine with convenient adjustment of spraying range can adjust the angle of the spray head, it cannot limit and comb the bending part of the pipeline when adjusting the angle. Even if the size of the spray head can be adjusted, the pipeline will cause the phenomenon of reducing the flow of concrete once it is bent. Not only does it affect the flow size of the concrete, but also it affects the spraying pressure of the concrete, thereby affecting the spraying effect of the concrete.

[0005] Therefore, a concrete spraying machine with angle adjustment is proposed to solve the problems mentioned above. SUMMARY

[0006] The purpose of the present application is to provide a concrete spraying machine with angle adjustment to solve the problem that the bending part of the pipeline cannot be limited and combed when adjusting the angle, even if the size of the spray head can be adjusted, the pipeline will cause the phenomenon of reducing the flow of concrete once it is bent.

[0022] 1. By setting the adjusting and protecting mechanism, the fixed ring can be sleeved on the end of the spraying conveying pipe, and the fixed knob is rotated to drive the fixed threaded rod to move in the fixed ring, so that the fixed threaded rod drives the fixed support blocks to approach each other, thereby clamping the spraying conveying pipe, when the spraying conveying pipe is bent due to the angle adjustment of the spraying nozzle, the large-angle bending of the spraying conveying pipe is avoided, which can reduce the concrete spraying amount or reduce the pressure, the second connecting ring is sleeved in the second expanding ring, and the second limiting ring and the third limiting ring are limited, under the limiting action of the second horn ring, the rotation angle of the third limiting ring and the second connecting ring is limited, so that the rotation angle of the second connecting ring, the second limiting ring and the second horn ring is less than fifteen degrees, through the mutual connection of the plurality of second connecting rings, second limiting rings and second horn rings, the rotation angle of the spraying conveying pipe is limited, not only can the spraying conveying pipe be protected and the rotation angle of the spraying conveying pipe be limited, but also can avoid the change of the concrete conveying flow caused by the too large rotation angle of the spraying conveying pipe, thereby affecting the spraying effect of the concrete, by starting the lifting motor to drive the lifting rotating rod and the bevel gear transmission assembly to rotate, the bevel gear transmission assembly drives the lifting threaded rod to rotate, at the same time, the lifting threaded sleeve drives the translation support and the spraying nozzle to move up and down, the spraying height of the spraying nozzle can be adjusted, at the same time, the translation motor is started to drive the first sprocket transmission assembly and the translation threaded rod to rotate, the translation limiting sleeve drives the rotating support and the spraying nozzle to move horizontally, the horizontal position of the spraying nozzle can be adjusted, the first rotating motor is started to drive the rotating worm to rotate, the rotating worm and the rotating worm wheel are engaged and connected, the rotating worm wheel drives the nozzle support and the spraying nozzle to rotate horizontally, the second rotating motor is started to drive the spraying nozzle to rotate vertically, the angle of the spraying nozzle can be adjusted, which is convenient for spraying concrete;

[0023] 2. By setting up a mobile mixing mechanism, not only can the entire concrete spraying machine be moved using a mobile vehicle, but the rotation of the rotating base also allows the first, second, and third receiving plates to rotate. This flips the rotating guide plate to one side of the wall, and the elastic force of the first and second springs enables the first, second, and third receiving plates to slide against each other, thus allowing the third receiving plate and the rotating guide plate to fit against the wall. This facilitates the recycling of sprayed concrete. Adjusting the motor drives the second sprocket transmission assembly and the adjusting screw... Rotating the lever causes the adjusting threaded sleeve to move the fixed support plate and lifting bracket longitudinally, adjusting the distance between the spray nozzle and the wall to be sprayed, thus improving the spraying effect of concrete. By adding concrete raw materials into the guide hopper and then into the mixing box through the guide pipe, the mixing motor is started to drive the mixing auger, the first mixing bracket and the second mixing bracket to rotate. The mixing auger realizes the vertical tumbling of the raw materials, and the first mixing bracket and the second mixing bracket realize the horizontal tumbling of the raw materials, thereby improving the mixing effect of the concrete raw materials and facilitating the subsequent spraying of concrete by the spray pump.

[0042] Please refer to Figure 5 , Figures 8-11The end of the mobile trolley 201 is fixedly provided with a chain wheel limiting cover 216, the inner side of the chain wheel limiting cover 216 is fixedly provided with an adjusting motor 217, the output end of the adjusting motor 217 is fixedly connected with a second chain wheel transmission assembly 218, the side of the second chain wheel transmission assembly 218 is symmetrically provided with an adjusting threaded rod 219, the outer side of the two adjusting threaded rods 219 is threadedly connected with an adjusting threaded sleeve 220, the adjusting threaded sleeve 220 is fixedly installed at the bottom of the fixed support plate 116, a mixing box 221 is fixedly installed at the top side of the mobile trolley 201, the top sides of the mixing box 221 are fixedly provided with a material guide pipe 222, the top of the two material guide pipes 222 is fixedly provided with a material guide hopper 223, the top center position of the mixing box 221 is fixedly provided with a mixing motor 224, the output end of the mixing motor 224 is fixedly connected with a mixing auger 225, the outer side of the mixing auger 225 is fixedly provided with a first mixing support 226, the bottom of the mixing auger 225 is fixedly provided with a second mixing support 227, the bottom side of the mixing box 221 is fixedly provided with a first pump pipe 228, the end of the first pump pipe 228 is fixedly connected with a jet pump 229, the output end of the jet pump 229 is fixedly connected with a jet conveying pipe 101, the adjusting threaded sleeve 220 drives the fixed support plate 116 and the lifting support 115 to move longitudinally by driving the second chain wheel transmission assembly 218 and the adjusting threaded rod 219 to rotate by the adjusting motor 217, the distance between the jet nozzle 133 and the wall to be jetted can be adjusted, the jetting effect of the concrete is improved, the raw materials of the concrete are added into the material guide hopper 223, and then enter into the mixing box 221 through the material guide pipe 222, the mixing auger 225, the first mixing support 226 and the second mixing support 227 are driven to rotate by starting the mixing motor 224, the raw materials are stirred up and down by the mixing auger 225, the raw materials are stirred horizontally by the first mixing support 226 and the second mixing support 227, so that the mixing effect of the raw materials of the concrete is improved, and the subsequent jetting of the concrete by the jet pump 229 is facilitated.

[0043] Working principle: before using the concrete jetting machine with angle adjustment, the overall situation of the device needs to be checked to determine whether it can work normally, according to Figure 1 - Figure 11As shown, first, the fixed ring 102 is sleeved on the end of the jet conveying pipe 101, and the fixed knob 104 is rotated to drive the fixed threaded rod 103 to move inside the fixed ring 102, so that the fixed threaded rod 103 drives the fixed support blocks 105 to approach each other, thereby clamping the jet conveying pipe 101. When the jet conveying pipe 101 is bent due to the angle adjustment of the jet nozzle 133, the jet conveying pipe 101 is prevented from being bent at a large angle to reduce the concrete jetting amount or the pressure. The second connecting ring 110, the second limiting ring 111 and the second horn ring 112 are limited. Since the second connecting ring 110 is sleeved inside the second enlarged ring 113 and is limited by the second limiting ring 111 and the third limiting ring 114, the third limiting ring 114 and the second connecting ring 110 are limited in rotation angle under the limiting action of the second horn ring 112. The rotation angle of the second connecting ring 110, the second limiting ring 111 and the second horn ring 112 is less than fifteen degrees. The rotation angle of the jet conveying pipe 101 is limited by the plurality of second connecting rings 110, the second limiting rings 111 and the second horn rings 112 connected to each other. Therefore, the rotation angle of the jet conveying pipe 101 is limited, which not only protects the jet conveying pipe 101 but also limits the rotation angle of the jet conveying pipe 101. The change of the concrete conveying flow caused by the too large rotation angle of the jet conveying pipe 101 is avoided, thereby affecting the concrete jetting effect.

[0044] Secondly, the lifting motor 117 is started to drive the lifting rotating rod 118 and the bevel gear transmission assembly 119 to rotate, so that the bevel gear transmission assembly 119 drives the lifting threaded rod 120 to rotate, and at the same time, the lifting threaded sleeve 121 drives the translation support 122 and the jet nozzle 133 to move up and down, so that the jetting height of the jet nozzle 133 can be adjusted. At the same time, the translation motor 123 is started to drive the first sprocket transmission assembly 124 and the translation threaded rod 125 to rotate, so that the translation limiting sleeve 126 drives the rotating support 127 and the jet nozzle 133 to move horizontally, and the horizontal position of the jet nozzle 133 can be adjusted. The first rotating motor 128 is started to drive the rotating worm 129 to rotate, and the rotating worm 129 and the rotating worm wheel 130 are engaged and connected, so that the rotating worm wheel 130 drives the nozzle support 131 and the jet nozzle 133 to rotate horizontally. The second rotating motor 132 is started to drive the jet nozzle 133 to rotate vertically, so that the angle of the jet nozzle 133 can be adjusted, and the concrete jetting is facilitated.
