In this embodiment, please refer to fig. 1, it can be seen that: the controllable mobile platform comprises a mobile chassis 1 with wheels 2, a field controller 3 is arranged on the mobile chassis 1, and the wheels 2 are Mecanum wheels, rail wheels or rubber wheels. The wheels 2 are provided with three groups, namely front, middle and rear groups, each wheel 2 is provided with an independently controlled walking driving motor on the mobile chassis 1, the field controller 3 is operated by a field operator to control the movement of the spraying unit and the start-stop operation of each device, the field controller 3 is arranged at the rear side of the controllable mobile platform, during construction operation, an operator walks and follows the rear side of the controllable mobile platform, the front side is additionally provided with an operator to perform specific spraying operation, and the operator inputs control instructions to the spraying unit through the field controller 3 according to observed field working conditions and working condition information acquired through communication with the front operator.
The mobile chassis 1 is provided with a storage battery pack, a control module and a driving module, wherein the storage battery pack is used for supplying power, the control module receives a control signal from the site controller 3 and sends an instruction to the driving module, and the driving module receives the instruction and controls the operation of motors (including a walking driving motor and a driving motor of each device). It is of course conceivable that the spraying unit may also be wired, in which case it is connected to a power supply provided at the construction site by means of a cable.
As mentioned above, the wheels 2 may be selected from three types of wheels, i.e. Mecanum wheels, rail wheels or rubber wheels, one of which is selected according to specific field conditions. The wheels 2 in the form of Mecanum wheels support the omnidirectional movement of the jet unit, which enables the jet unit to move more flexibly, but with certain requirements on the flatness and hardness of the ground. Wheels 2 in the form of rail wheels require a walking track to be installed on site, in which case the jet unit moves along the ground track.

Referring to fig. 6, 7, 8 and 9, it can be seen that:
the middle upper part of the rotating shaft 14-6 is a square shaft section, a square shaft hole is arranged in the center of the rotor 14-4, and the square shaft section is arranged in the square shaft hole in a penetrating way, so that the rotor driver 14-1 directly drives the rotor 14-4 to rotate through the rotating shaft 14-6. The impeller 14-3 is mounted and fixed on top of the rotating shaft 14-6, so that the rotor driver 14-1 simultaneously drives the rotor 14-4 and the impeller 14-3 to rotate. Since the bottom plate 14-8 is fixedly coupled with the base 14-2, the bottom plate 14-8 is not rotated, and the top plate 14-9 is floatingly placed on top of the rotor 14-4 (the position of which is defined after the rotor spraying device 14 is assembled) and is not rotated, so that the rotor 14-4 is sandwiched between the bottom plate 14-8 and the top plate 14-9 and stably rotated.
As shown in fig. 8, the rotor 14-4 has a cylindrical shape as a whole, and a plurality of vertically penetrating passages through which concrete mix passes from top to bottom are arranged at equal angular intervals in the circumferential direction on the main body of the rotor 14-4. The number of the channels is 12, and the cross sections of the channels are all sector-ring-shaped. The rotor 14-4 is integrally formed by a metal block (milling and other processes) to ensure the machining precision, and it is worth noting that the top surface of the rotor 14-4 is in running fit with the bottom surface of the top plate 14-9, the bottom surface of the rotor 14-4 is in running fit with the top surface of the bottom plate 14-8, and the contact position should have higher matching precision (fine machining should be performed on the top surface and the bottom surface of the rotor 14-4, the bottom surface of the top plate 14-9 and the top surface of the bottom plate 14-8), so that the problem of material leakage at the matching position can be avoided or reduced, and of course, a small amount of material leakage at the matching position is allowed, and the normal operation of the jet unit is not affected.
The top plate 14-9 is provided with a blanking hole 14-10 and an air inlet hole 14-11, and the bottom plate 14-8 is provided with a containing hole 14-14 aligned with the blanking hole 14-10 above and a discharging hole 14-13 aligned with the air inlet hole 14-11 above. Below the base 14-2 is mounted a discharge pipe 14-5 with a lower inlet port 14-7 at the rear and a clearance assembly 28 for cleaning the passageway of the rotor 14-4 above.
The blanking hole 14-10 is in a fan-shaped shape, the width of the blanking hole is obviously larger than that of a channel on the rotor 14-4, concrete mixture above the rotor 14-4 downwards passes through the blanking hole 14-10 and enters the channel on the rotor 14-4, the mixture in the channel moves along with the rotation of the rotor 14-4 in the rotating process, compressed air is blown downwards at the position of the air inlet hole 14-11, so that the mixture in the channel moving below the air inlet hole 14-11 is extruded and blown downwards by high-pressure air flow, at the moment, the mixture downwards passes through the discharging hole 14-13 and enters the discharging pipe 14-5, meanwhile, the other part of compressed air enters the discharging pipe 14-5 through the lower air inlet interface 14-7, further extrusion and blowing effects are generated on the mixture entering the discharging pipe 14-5, and the mixture is extruded and discharged from the discharging pipe 14-5.
The rotor spraying device 14 also comprises an openable and closable transfer hopper 13, wherein the stirring impeller 14-3 is positioned at the bottom of the inner cavity of the transfer hopper 13 when the transfer hopper 13 is closed.

The function of the corrugated pipe 11 is to establish buffer elastic connection between the conveying pipeline 8 and the transfer hopper 13, so that inconvenience caused by rigid connection is avoided, and meanwhile, the corrugated pipe 11 with certain flexibility is convenient for opening and closing the transfer hopper 13.
The conveying pump 7 conveys the concrete mixture to the inside of the transfer hopper 13, so that the inside of the transfer hopper 13 is gradually filled with the mixture and extrusion pressure is built, and therefore, the mixture in the transfer hopper 13 enters the channel of the rotor 14-4 downwards in an active extrusion mode, and the problem of idling of the rotor 14-4 caused by the fact that the mixture cannot smoothly enter the channel of the rotor 14-4 in a gravity blanking mode is solved. On the other hand, as described above, when the intermediate transfer hopper 13 is closed and the mixture is injected into the interior, the stirring impeller 14-3 which rotates in synchronization with the rotor 14-4 imparts a continuous stirring action to the mixture in the intermediate transfer hopper 13, and the fluidity of the mixture (to avoid setting) can be ensured while promoting further sufficient mixing of the components of the concrete mixture. In this embodiment, in order to further improve fluidity of the mixture, a vibration motor 12 may be installed outside the transfer hopper 13, and a moderate vibration effect is generated by the vibration motor 12 during construction, so as to promote the mixture in the hopper to enter the channel of the rotor 14-4 downward.
The purpose of the openable and closable structure of the transfer hopper 13 is to clean the interior periodically, so that the main body of the rotor spraying device 14 can be quickly assembled and disassembled and deeply cleaned.
