[0038] In a preferred embodiment: the outer tube body 1 includes a bellows 101, and both ends of the bellows 101 are fixedly assembled with straight tubes 102;

[0039] The upper and lower ends of the driving frame 3 are both located at the connection points of the two groups of straight tubes 102 and the corrugated tube 101 .

[0040] In the above structure, the outer tube body 1 can bend by driving the straight tube 102 through the bellows 101, and the upper and lower ends of the driving frame 3 are located at the connection between the two groups of straight tubes 102 and the bellows 101, so that the driving frame 3 can drive the outer tube body 1 to bend.

[0041] In a preferred embodiment: the operating frame 2 is located at the bottom of the driving frame 3, and the operating frame 2 includes a mounting ring 201, and a control rocker 202 and a controller 203 are respectively provided on the top of the mounting ring 201;

[0042] The control joystick 202 , the driving frame 3 and the humidity sensor 11 are all electrically connected to the controller 203 .

[0043] In the above structure, the construction personnel controls the control rocker 202 to control the driving frame 3 through the controller 203 to operate, so that the personnel do not need to pull the material tube to bend it at a certain angle to achieve material discharge at different positions, which is convenient for manual adjustment of the material discharge position.

[0044] In a preferred embodiment: the driving frame 3 includes two sets of upper and lower fixing components, and the outer walls of the upper and lower fixing components are rotatably connected to the telescopic rod 303;

[0045] The fixing assembly includes two sets of curved plates 301. The opposite sides of the two sets of curved plates 301 are fixedly equipped with support rods 302. The ends of the support rods 302 away from the curved plates 301 are rotatably connected to the telescopic rods 303.

[0046] The outer wall of the bottom group of support rods 302 is fixedly mounted with a snap-fit ​​buckle 304 .

[0047] In the above structure, the upper and lower sets of fixing components are respectively fixedly assembled with the two sets of straight tubes 102, and one or more sets of telescopic rods 303 are used to extend and retract, thereby driving the distance between the upper and lower sets of fixing components to change, thereby achieving the bending of the outer tube body 1 by the two sets of fixing components;

[0048] By simultaneously extending and retracting the plurality of telescopic rods 303, the distance between the upper and lower fixed components is changed, thereby achieving the extension and retraction of the outer tube body 1.

[0049] In actual work, there is a problem that the concrete mold will fall over when pouring concrete. During the pouring process, workers need to hold the equipment by hand and stand on the top of the mold to pour. Therefore, when the concrete mold falls over, the workers have nothing to support themselves.

[0050] By setting up the snap-on buckle 304, the staff can wear the protective equipment and snap the protective equipment to the snap-on buckle 304. When the equipment in this application is in use, it is connected to the output end of the concrete pump truck through the connecting buckle 4, so that personnel can realize emergency lifting of personnel through the concrete pump truck.

[0051] In a preferred embodiment, the ultrasonic generator 12 is fixedly assembled to the inner wall of a group of straight tubes 102 located at the bottom of the bellows 101 , and the fixing ring 8 is fixedly assembled to the top of a group of straight tubes 102 located at the top of the bellows 101 .

[0052] In the above structure, the ultrasonic generator 12 and the straight tube 102 are fixedly assembled, so that when the bellows 101 is extended and retracted by the driving frame 3, the straight tube 102 can drive the ultrasonic generator 12 located on the outer wall of the inner tube body 6 to slide up and down;

[0053] By setting up the ultrasonic generator 12, the ultrasonic waves generated by the ultrasonic generator 12 during operation are transmitted to the inner tube body 6, so that the air in the concrete located on the inner tube body 6 and the inner wall of the filter cloth 13 can vibrate through the ultrasonic waves, thereby discharging the air in the concrete.

[0054] In a preferred embodiment, the filter cloth 3 15 is fixedly assembled with a group of clamping rings 10 located on the top of the fixing ring 8 , and the filter cloth 2 14 is located outside the outer tube body 1 .

[0055] In the above structure, the filter cloth 3 15 is fixed by the clamping ring 10, so that the filter cloth 13 is located in the inner cavity of the inner tube body 6. The filter cloth 13 isolates the concrete, so that the concrete does not overflow between the inner tube body 6 and the outer tube body 1 through the permeable hole 7. At the same time, the filter cloth 13 and the filter cloth 3 15 isolate the concrete, so that the concrete does not adhere to the inner wall of the inner tube body 6, thereby increasing the ease of cleaning of the equipment.

[0056] On the other hand, the filter cloth 13, the filter cloth 2, and the filter cloth 3, 15, absorb the liquid in the concrete and conduct the liquid to the humidity sensor 11, so that the humidity sensor 11 can detect the liquid content in the concrete. By comparing the liquid content data detected by the humidity sensor 11 with the data preset in the controller 203, when the humidity sensor 11 detects that the liquid content in the concrete is too low, the controller 203 issues an alarm.

[0057] The higher the liquid content, the better the concrete's workability generally is, meaning the concrete flows and is easier to place.

[0058] Too low a moisture content will result in concrete that is too dry and hard, making it difficult to pour and compact;

[0059] Therefore, by detecting the liquid content of the concrete through the humidity sensor 11, the staff can know in real time whether the quality of the concrete meets the standards;

[0060] On the other hand, the filter cloth two 14 is conical, so that the filter cloth two 14 can achieve a certain gathering effect on the concrete discharged from the filter cloth one 13, thus solving the problem of the concrete splashing everywhere when discharged.

[0061] In a preferred embodiment: the electronic one-way valve 16 is electrically connected to the controller 203, and the connecting pipe 5 is connected to the water tank.

[0062] In the above structure, a water pump is arranged in the water tank. When the humidity sensor 11 detects that the liquid content of the concrete is too low, the controller 203 gives an alarm. At the same time, the controller 203 controls the water pump to transfer the liquid in the water tank to the cavity between the outer tube body 1 and the inner tube body 6 through the connecting pipe 5. The ultrasonic generator 12 is fixedly assembled with the outer tube body 1, and the ultrasonic generator 12 is slidably sleeved with the inner tube body 6, so that the bottom of the cavity between the outer tube body 1 and the inner tube body 6 is sealed by the ultrasonic generator 12. Through the penetration holes 7, the water penetrates into the inner cavity of the inner tube body 6, and then the liquid content of the concrete is replenished, so that the concrete meets the construction standards.

[0063] In a preferred embodiment: the three stirring rods 17 are arranged in a "pin" shape.

[0064] In the above structure, through the stirring rods 17 arranged in a "pin" shape, the concrete flowing in the inner cavity of the filter cloth one 13

[0065] After contacting the uppermost stirring rod 17, it can be separated through the stirring rod 17. When the concrete flows downward, it can contact the other two stirring rods 17, and then the concrete is separated again through the stirring rod 17, so as to realize the mixing and stirring of the concrete by several stirring rods 17 arranged in a "pin" shape.

[0066] Working principle: The upper and lower two groups of fixing components are respectively fixedly assembled with the two straight pipes 102, and one or more telescopic rods 303 are used for telescoping, so as to change the distance between one side of the upper and lower two groups of fixing components, and thus realize the bending of the outer tube body 1 driven by the two groups of fixing components;

[0067] The construction worker controls the control rocker 202, so that the control rocker 202 controls the driving frame 3 to operate through the controller 203, so that the personnel do not need to pull the material pipe to bend at a certain angle to realize the blanking at different positions, which is convenient for manual adjustment of the blanking position;

[0068] By simultaneously telescoping several telescopic rods 303, the distance between the upper and lower two groups of fixing components is changed, so as to realize the telescoping of the outer tube body 1;

[0069] Fixedly assembled through the ultrasonic generator 12 and the straight pipe 102, when the corrugated pipe 101 expands and contracts through the driving frame 3, the straight pipe 102 can drive the ultrasonic generator 12 to slide up and down on the outer wall of the inner pipe body 6;

[0070] By setting the ultrasonic generator 12, the ultrasonic waves generated when the ultrasonic generator 12 operates are conducted to the inner pipe body 6, so that the air in the concrete located on the inner wall of the inner pipe body 6 and the filter cloth one 13 can be vibrated by the ultrasonic waves, thereby discharging the air in the concrete;

[0071] When the equipment is not in use, by injecting clean water into the inner cavity of the equipment, and the ultrasonic generator 12 slides on the outer wall of the inner pipe body 6, the equipment can achieve self-cleaning;

[0072] The filter cloth three 15 is fixed by the snap ring 10, and the filter cloth one 13 is located in the inner cavity of the inner pipe body 6. The concrete is isolated by the filter cloth one 13, so that the concrete will not overflow to the space between the inner pipe body 6 and the outer pipe body 1 through the permeation holes 7. At the same time, the concrete is isolated by the filter cloth one 13 and the filter cloth three 15, so that the concrete will not adhere to the inner wall of the inner pipe body 6, thereby increasing the easy cleaning property of the equipment;

[0073] On the other hand, the filter cloth one 13, the filter cloth two 14 and the filter cloth three 15 are used to absorb the liquid in the concrete and conduct the liquid to the humidity sensor 11, so that the humidity sensor 11 can detect the content of the liquid in the concrete. By comparing the liquid content data detected by the humidity sensor 11 with the preset data in the controller 203, when the humidity sensor 11 detects that the liquid content in the concrete is too low, the controller 203 gives an alarm;

[0074] When the humidity sensor 11 detects that the liquid content in the concrete is too low, the controller 203 gives an alarm. At the same time, the controller 203 controls the water pump to transfer the liquid in the water tank to the cavity between the outer pipe body 1 and the inner pipe body 6 through the connecting pipe 5. Fixedly assembled through the ultrasonic generator 12 and the outer pipe body 1, the ultrasonic generator 12 is sleeved on the inner pipe body 6 in a sliding manner, so that the bottom of the cavity between the outer pipe body 1 and the inner pipe body 6 is sealed by the ultrasonic generator 12. Through the permeation holes 7, the water permeates into the inner cavity of the inner pipe body 6, thereby realizing the supplement of the liquid content of the concrete, so that the concrete meets the construction standards;

[0075] Through the stirring rods 17 arranged in a "pin" shape, the concrete is separated by the stirring rods 17, thereby realizing the mixing and stirring of the concrete by a number of stirring rods 17 arranged in a "pin" shape.
