The working principle of the wall plastering system in the embodiment is as follows:

the method for adjusting the position of the vehicle body and the position of the plastering device before plastering comprises the following steps:

the first step is as follows: placing the flat car at a certain distance from the plastered wall surface, controlling a third motor 302 of a first driving wheel mechanism by a motor controller to drive a first driving wheel set 301 to drive the flat car to move forward, processing detection data of a first sensor and a second sensor by the motor controller during the moving process of the flat car, and if the distance difference between the front part of the side surface and the rear part of the side surface of the flat car frame detected by the first sensor and the second sensor is not within a set threshold range, indicating that the moving direction of the flat car and the body of the flat car are not parallel to the plastered wall surface, controlling an electric cylinder 204 of a steering wheel mechanism by the motor controller to drive a bogie 201 to rotate around a hinge shaft 203 to adjust the moving direction of the flat car until the distance difference between the front part of the side surface and the rear part of the side surface detected by the first sensor and the second sensor is within the set threshold range, so as to ensure that the body of the flat car is parallel to the plastered wall surface. And in the process that the flat car advances, the controller also judges whether the flat car collides with a wall surface according to the detection values of the first sensor, the second sensor and the third sensor so as to ensure the driving safety.

The second step is that: under the condition that the advancing direction of the flat car is parallel to the plastered wall surface, the motor controller controls the third motor to stop working according to whether the distance between the side surface of the flat car frame and the plastered wall surface detected by the first sensor and the second sensor is within a set threshold range, if the detected distance is not within the set threshold range, the motor controller controls the telescopic rods of the electric cylinders in the electric cylinder group 11 to extend out simultaneously so as to raise the height of the flat car frame and separate the wheels of the first wheel mechanism from the ground, and then the fourth motor 1002 controlling the second driving wheel mechanism 10 drives the second driving wheel set 1001 so as to enable the distance between the flat car frame and the plastered wall surface to be within the set threshold range. And then the telescopic rods of the electric cylinders in the electric cylinder group 11 are controlled to retract simultaneously, so that the wheels of the first wheel mechanism contact the ground again.

The third step: the motor controller controls the electric push rod 25 to drive the plastering device 24 to move forwards, so that the distance of the discharge port of the plastering device 24 for feeding the plastered wall surface is in a set threshold range.

The positions of the vehicle body and the plastering device are adjusted to a set range through the steps, and then the motor controller can control the flat car to move forward or backward for plastering operation.

The mortar raw materials are manually poured into a mixing hopper 28 of the mortar supply device, the gate valve is opened after the raw materials are uniformly stirred by the stirrer, and the mixed mortar enters the screw conveyor below. In the plastering operation process, the mortar is sent into the transfer container of the mortar distributor through the mortar conveying pipe by the screw conveyer and then is sent into the discharge chute of the mortar distributor through the mortar distributing pipe, the mortar distributor ensures that the mortar is uniformly distributed in the length direction of the discharge chute, and further ensures that the 24 discharge chute of the mortar distributor can uniformly discharge the mortar and coat the mortar on the wall surface.

When the third sensor detects that the distance from the front end of the flat car to the front wall surface reaches a set threshold range in the process of moving the flat car forwards and plastering, or when the fourth sensor detects that the distance from the rear end of the flat car to the rear wall surface reaches a set threshold range in the process of moving the flat car backwards and plastering, the motor controller firstly controls the first motor 15 of the first translation device to drive the screw rod 12 to rotate, so that the plastering device 24 moves from one end of the flat car frame to the other end, and thus, one-time wall surface transverse movement plastering is completed. After finishing one-time wall surface transverse moving plastering, the motor controller controls the second motor 20 of the lifting power mechanism to drive the lifting slide plate to move upwards for a set distance, thereby carrying out the next wall surface transverse moving plastering operation.

During the plastering process of the plastering plate of the plastering device, redundant materials can be discharged from the space between the lower excess material outlet 2428 and the upper two edge material level cutting plates 2426. The rim charge level cutting plate can level the upper side edge of a mortar layer smeared on a wall surface, and is favorable for lap joint with the edge part of the next section of mortar when the mortar smearing device touches the next section of mortar. And because the mortar spreader is provided with the seam rendering coat 2424, when the seam rendering coat passes through the lap seam of the upper section of mortar and the lower section of mortar, the mortar at the seam rendering coat is extruded, so that the seam can be healed smoothly, and due to the existence of the guide edges 2427, the smoothed lower section of mortar layer can not be scraped when the seam rendering coat moves forwards, and meanwhile, due to the existence of the excess material baffle 2425, the excess material baffle has a protection effect on the lower side smoothed mortar layer, so that the excess mortar overflows from the excess material outlet 2428, and the extrusion damage to the lower side smoothed mortar layer can not be caused.

Wall plastering system in this embodiment, its distance between ability automatic adjustment automobile body and plastering ware and the wall guarantees the continuous of the operation of plastering and goes on, has solved the problem that current mechanical float needs artifical frequent installation and adjustment position mechanical float and the problem that current mechanical float needs artifical mixed mortar and material loading at the operation in-process of plastering, can very big improvement work efficiency of plastering.

As an improvement to the above embodiment, the vertical frame is composed of a plurality of sections connected by bolts, the vertical guide rail is cylindrical, the vertical guide rail is composed of a plurality of sections connected by threads, and the support plate is fixed on the lifting slide plate by bolts. The improvement enables the positioning and moving mechanism of the plastering machine to be detachable and convenient to transport.

Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
