[0037] The working principle of the wall plastering system in this embodiment is as follows:

[0038] The position of the vehicle body and the position of the plastering device before plastering include the following steps:

[0039] The first step: place the flatbed car at a certain distance from the plastered wall, and then the motor controller controls the third motor 302 of the first driving wheel mechanism to drive the first driving wheel group 301 to make the flatbed car move forward. During the flatbed car's forward movement, the motor controller processes the detection data of the first sensor and the second sensor. If the distance difference between the front side and the rear side of the flatbed frame detected by the first sensor and the second sensor and the plastered wall is not within the set threshold range, it means that the forward direction of the flatbed car and the body of the flatbed car are not parallel to the plastered wall. In this case, the motor controller controls the electric cylinder 204 of the steering wheel mechanism to push the bogie 201 to rotate around the articulated shaft 203 to adjust the forward direction of the flatbed car until the distance difference between the front side and the rear side of the flatbed car detected by the first sensor and the second sensor and the plastered wall is within the set threshold range to ensure that the body of the flatbed car is parallel to the plastered wall. In addition, during the flatbed car's forward movement, the controller also determines whether the flatbed car will collide with the wall according to the detection values ​​of the first sensor, the second sensor and the third sensor to ensure driving safety.

[0040] Step 2: When the flatbed vehicle is parallel to the plastered wall, the motor controller detects whether the distance between the side of the flatbed vehicle frame and the plastered wall is within the set threshold range according to the first sensor and the second sensor. If the measured distance is not within the set threshold range, the motor controller first controls the third motor to stop working, and then controls the telescopic rods of each electric cylinder in the electric cylinder group 11 to extend at the same time to raise the height of the flatbed vehicle frame so that the wheels of the first wheel mechanism are off the ground, and then controls the fourth motor 1002 of the second drive wheel mechanism 10 to drive the second drive wheel group 1001 so that the distance between the flatbed vehicle frame and the plastered wall is within the set threshold range. Then, the telescopic rods of each electric cylinder in the electric cylinder group 11 are controlled to retract at the same time so that the wheels of the first wheel mechanism are in contact with the ground again.

[0041] Step 3: The motor controller controls the electric push rod 25 to drive the plastering device 24 to move forward, so that the distance between the discharge port of the plastering device 24 and the plastered wall surface is within a set threshold range.

[0042] Through the above steps, the position of the vehicle body and the plastering device is adjusted to the set range, and then the motor controller can control the flatbed truck to move forward or backward to perform the plastering operation.

[0043] The mortar raw materials are manually poured into the mixing hopper 28 of the mortar supply device. After the raw materials are evenly stirred by the agitator, the gate valve is opened, and the mixed mortar enters the screw conveyor below. During the plastering operation, the mortar is sent from the screw conveyor to the transfer container of the mortar distributor through the mortar delivery pipe, and then sent to the discharging trough of the mortar spreader through the material distribution pipe. The mortar distributor ensures that the mortar is evenly distributed in the length direction of the discharging trough, thereby ensuring that the discharging trough of the mortar spreader 24 can evenly spit out the mortar and apply it to the wall surface.

[0044] When the third sensor detects that the distance between the front end of the flatbed truck and the front wall reaches the set threshold range during the forward movement of the flatbed truck, or when the fourth sensor detects that the distance between the rear end of the flatbed truck and the rear wall reaches the set threshold range during the backward movement of the flatbed truck, the motor controller first controls the first motor 15 of the first translation device to drive the screw 12 to rotate, so that the plastering device 24 moves from one end of the flatbed truck frame to the other end, thus completing a wall transverse plastering operation. After completing a wall transverse plastering operation, the motor controller controls the second motor 20 of the lifting power mechanism to drive the lifting slide plate to move up a set distance, so as to perform the next wall transverse plastering operation.

[0045] During the screeding process of the screeding plate of the screeding device, the excess will be discharged from the lower residual material outlet 2428 and the upper two edge material flush cutting plates 2426. The edge material flush cutting plate can cut the upper side edge of the mortar layer applied on the wall surface flush with the height, which is conducive to the overlap of the edge of the next section of mortar when the screeding device touches the upper section of mortar. In addition, since the screeding device is provided with a seam screed plate 2424, the seam screed plate squeezes the mortar at the seam when passing through the overlapping seam of the upper and lower sections of mortar, so that the seam can be healed and leveled. In addition, due to the existence of the guide edge 2427, the seam screed plate will not scratch the applied lower section of mortar layer when moving forward. At the same time, due to the existence of the residual material baffle plate 2425, the residual material baffle plate has a protective effect on the applied mortar layer on the lower side, so that the excess mortar overflows from the residual material outlet 2428 without causing extrusion damage to the applied mortar layer on the lower side.

[0046] The wall plastering system in this embodiment can automatically adjust the distance between the body and the plastering machine and the wall to ensure the continuous progress of the plastering operation. It solves the problem that the existing plastering machine needs to be frequently installed and adjusted manually during the plastering operation, and the problem that the existing plastering machine needs to be manually mixed with mortar and loaded, which can greatly improve the efficiency of the plastering operation.

[0047] As an improvement to the above embodiment, the stand is composed of several sections connected by bolts, the vertical guide rail is cylindrical, and the vertical guide rail is composed of several sections connected by threads, and the support plate is fixed on the lifting slide plate by bolts. This improvement makes the positioning and moving mechanism of the plastering machine detachable for easy transportation.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
