[0016] Preferably, the material of one end of the receiving plate is rubber.

[0017] Preferably, the use method of the wall painting device for building construction comprises the following steps:

[0018] S1: the user pushes the lower box to the surface of the wall, at this time one end of the arc-shaped guide frame is close to the wall, at this time the arc-shaped guide frame pushes the connecting rod to move into the groove, so that the first spring telescopic rod retracts, at this time the fixed plate on the connecting rod slides in the limiting groove, ensuring that the connecting rod moves horizontally into the groove, and the connecting rod is stable when the connecting rod is pulled to deflect, at this time the spring telescopic rod group is deflected and moves towards the wall, when the multiple receiving plates on one end of the spring telescopic rod group are in contact with the wall, the multiple receiving plates are in contact with the surface of the wall at the same time and push the single spring telescopic rod group corresponding to the spring telescopic rod group to retract, ensuring that the multiple receiving plates are stably attached to the wall surface, facilitating subsequent material receiving;

[0019] S2: when the spring telescopic rod group deflects, it drives the ratchet disc to rotate counterclockwise, then the spring telescopic rod group and the limiting spring telescopic plate cooperate to resist the ratchet disc tooth groove, avoiding the spring telescopic rod group from returning to its original position, at this time the user fixes the device;

[0020] Then the user runs the paint roller, then the material in the material box is transported to the paint roller through the conveying pump, the hydraulic telescopic rod drives the paint roller to move up and down to paint the wall, and the multiple receiving plates receive the falling material, and the received material falls into the transmission belt in the groove through the gap between the inclined spring telescopic rod groups, and the material is collected;

[0021] S3: when the user finishes painting the wall, first step on the cylindrical rod with the foot, prompting the cylindrical rod to drive the L-shaped plate to deflect and press the second spring telescopic rod, and at the same time drive the limiting spring telescopic plate to move out of the tooth groove on the side of the ratchet disc, at this time the second spring telescopic rod slowly extends, the user moves the device away from the wall, at this time the first spring telescopic rod extends, prompting the receiving plate to deflect and reset away from the wall, lifting the material on the receiving plate, so that it is better guided into the gap on the spring telescopic rod group, facilitating timely processing of the material on the receiving plate, one end of the arc-shaped guide frame is stably attached to the wall, facilitating secondary receiving of a small amount of material falling between the deflected receiving plate and the wall, ensuring the effect of the device on material collection;

[0022] When the connecting rod is pushed by the first spring telescopic rod, the connecting rod deflects to drive the transmission rod to deflect and pull the sliding frame to slide on the connecting rod, and the wedge block on the upper side of the sliding frame moves to drive the transmission belt to rotate clockwise, and the material box on the surface of the transmission belt is transported into the collection box, facilitating the collection of the material on the transmission belt;

[0023] Then when the device is close to the wall surface again, the transmission rod is deflected to pull the sliding frame to slide on the connecting rod, so that the spring expansion plate pushes the wedge block to move, drives the transmission belt to rotate clockwise, further reduces the residual material on the transmission belt, and the user is more convenient for collecting the material; and when the first spring expansion rod is elongated, the hinged plate moves to one side of the inner wall of the collecting box, then when the first spring expansion rod is retracted, the hinged plate flattens the material in the collecting box, and the collecting box can better collect the material.

[0024] Compared with the prior art, the beneficial effects of the present application are:

[0025] In the present application, by pushing the lower box to approach the surface of the wall, one end of the arc-shaped flow guide frame approaches the wall first, at this time, the arc-shaped flow guide frame pushes the connecting rod to move into the groove together with the connecting frame, so that the first spring expansion rod retracts, at this time, the fixed plate on the connecting rod slides in the limiting groove, ensuring that the connecting rod moves horizontally into the groove while stably pulling the connecting rod to deflect, at this time, the spring expansion rod group is deflected by the pulling force and moves towards the wall, when the multiple receiving plates at one end of the spring expansion rod group abut against the wall, the multiple receiving plates abut against the surface of the wall at the same time and push the single spring expansion rod assembly corresponding thereto on the spring expansion rod group to retract, ensuring that the multiple receiving plates are stably attached to the wall surface, facilitating subsequent material receiving.

[0026] In the present application, after the material in the material box is conveyed to the powder roller by the conveying pump, the hydraulic expansion rod drives the powder roller to move up and down to paint the wall, and the multiple receiving plates receive the falling material, and the received material falls into the gap between the inclined spring expansion rod groups and falls onto the transmission belt in the groove, so that the material is collected.

[0027] In the present application, when the user finishes painting the wall, the user first steps on the cylindrical rod to drive the cylindrical rod to deflect and press down the second spring expansion rod, and at the same time drives the limiting spring expansion plate to move out of the tooth groove on the side of the ratchet disc, at this time, during the slow elongation of the second spring expansion rod, the user moves the device away from the wall, at this time, the first spring expansion rod is elongated, the receiving plate is deflected and reset away from the wall, the material received on the receiving plate is lifted up, so that it is better guided into the gap on the spring expansion rod group, facilitating timely processing of the material on the receiving plate, one end of the arc-shaped flow guide frame is stably attached to the wall, facilitating secondary receiving of a small amount of material falling between the deflected receiving plate and the wall, and ensuring the effect of collecting the material by the device.

[0028] In this invention, when the connecting rod is pushed by the first spring telescopic rod to reset, the connecting rod deflects, causing the transmission rod to deflect and pull the slide on the connecting rod. This pushes the wedge block on its upper side to move, causing the transmission belt to rotate clockwise and transport the material box on its surface into the collection box, facilitating the collection of material on the transmission belt. Then, when the device is close to the wall again, the transmission rod deflects, pulling the slide on the connecting rod, causing the spring telescopic plate to push the wedge block to move, driving the transmission belt to rotate clockwise, further reducing the material residue on the transmission belt and making it more convenient for the user to collect the material. Furthermore, when the first spring telescopic rod extends, the hinge plate moves to one side of the inner wall of the collection box. Then, when the first spring telescopic rod retracts, it drives the hinge plate to flatten the material inside, increasing the collection box's ability to collect material more effectively.

At this time, while the second spring telescopic rod (95) slowly extends, the user moves the device to the side away from the wall. At this time, the first spring telescopic rod (71) extends, causing the receiving plate (86) to deflect and reset away from the wall, lifting the material received on the receiving plate (86) so that it can be better guided into the gap on the spring telescopic rod assembly (85), making it easier to process the material on the receiving plate (86) in time. One end of the arc-shaped guide frame (711) is stably attached to the wall, making it easier to receive the small amount of material that falls between the receiving plate (86) and the wall when deflecting, ensuring the effect of the device in collecting materials. When the connecting rod (73) is pushed by the first spring telescopic rod (71) to reset, the connecting rod (81) deflects and drives the transmission rod (82) to deflect and pull the slide (83) to slide on the connecting rod (73), and pushes the wedge block (77) on its upper side to move and drive the transmission belt (76) to drive clockwise, conveying the material box on its surface into the collection box (10), so as to facilitate the collection of the material on the transmission belt (76); Then, when the device is close to the wall again, the transmission rod (82) deflects and pulls the slide (83) to slide on the connecting rod (73), causing the spring telescopic plate (84) to push the wedge block (77) to move, driving the transmission belt (76) to rotate clockwise, further reducing the material residue on the transmission belt (76), making it more convenient for the user to collect the material; and when the first spring telescopic rod (71) extends, the hinge plate (11) moves to one side of the inner wall of the collection box (10), and when the first spring telescopic rod (71) retracts, it drives the hinge plate (11) to flatten the material in the collection box (10), increasing the collection box (10) to collect the material better.
