For example, a space is provided between the left push rod 31 and the left end face of the plastering plate 20, when the distributing mechanism 80 stops distributing material on the left side of the plastering frame 10, the discharge port 821 of the distributing pipe 82 is located above the space, and at this time, mortar overflowing from the discharge port 821 does not fall on the push rod 31, the nut 32, the first bevel gear 33, the transmission mechanism 40 and the driving motor 51 even though the mortar drops, so that pollution of the mortar to the connection position of each component is avoided, for example, the influence of the mortar on the hinge joint between the push rod 31 and the plastering plate 20 can be avoided, and the action of the push rod 31 is protected. The right push rod 31 and the right end face of the plastering plate 20 have a spacing space therebetween, and when the distributing mechanism 80 stops distributing on the right side of the plastering frame 10, mortar overflowing from the discharge port 821 does not fall on the right push rod 31, the nut 32, the first bevel gear 33, the transmission mechanism 40 and the driving motor 51 even if the mortar drips.

It should be noted that the translation assembly 81 may be a linear module, specifically, the linear module may be a linear motor module or a ball screw module, so as to drive the distribution pipe 82 to move, and the control is simple and the motion is stable.

As shown in fig. 4 and 5, further, an avoiding mechanism 90 is disposed inside the discharge port 821 of the distributing pipe 82 in the partition space, and the avoiding mechanism 90 includes: a roller 8302, a sleeve 9101, a swinging rod 9102, an elastic piece (not shown) and a guide plate (not shown).

The roller 8302 is installed above the distribution mechanism 80. The sleeve 9101 is rotatably connected to the plastering frame 10. One end of the swing rod 9102 is slidably arranged in the sleeve 9101, the other end of the swing rod 9102 is connected with the bottom of the cloth mechanism 80, and a sliding part (not shown) is arranged on the swing rod 9102. The elastic member is located between the sliding portion and the sleeve 9101. The guide plate is provided with guide grooves (not shown) formed in an arc shape, and the sliding portion can be adapted to the guide grooves to slide. For example, when the plastering plate 20 moves to the topmost end of the wall surface, the roller 8302 is in contact with the ceiling, the ceiling exerts a downward force on the swing rod 9102 through the roller 8302 and the cloth mechanism 80, the swing rod 9102 drives the cloth mechanism 80 to swing to the rear lower part of the plastering frame 10 along the arc-shaped groove, so that an avoiding effect is realized, the plastering plate 20 can continuously move upwards to the space avoided by the cloth mechanism 80, and the plastering of the plastering plate 20 to the topmost end of the wall surface is ensured.

Specifically, the sleeve 9101 can rotate relative to the plastering frame 10, one end of the swing rod 9102 is arranged in the sleeve 9101, one end of the swing rod 9102 can slide in the sleeve 9101 along the extension direction of the sleeve 9101, and the other end of the swing rod 9102 extends out of the sleeve 9101 and is fixedly connected with the cloth mechanism 80. The guide plate is arranged on the outer side of the sleeve 9101, the sliding part on the swing rod 9102 can penetrate through the sleeve 9101 and is matched in a guide groove of the guide plate, and the sliding part moves to the rotation center of the sleeve 9101 along the guide groove when the distributing pipe 82 moves from the distributing position to the avoiding position.

Wherein, the guide way can form into the arc form, when pendulum rod 9102 reciprocates for plastering plate 20, can drive the sliding part and reciprocate, because of the sliding part cooperation in curved guide way, the sliding part plays the guide effect with the guide way cooperation to the removal of pendulum rod 9102, makes pendulum rod 9102 drive cloth mechanism 80 and rotates in the side concertina movement limit in established route.

The elastic piece is located between sliding part and sleeve 9101, that is to say, the one end and the sliding part butt of elastic piece, the other end and the diapire butt of sleeve 9101 of elastic piece to make the diapire of sleeve 9101 can play limiting displacement to the elastic piece. In the process that the distributing pipe 82 moves from the distributing position to the avoiding position, the sliding part moves along the direction of the guide groove, and extrudes the elastic part, so that the elastic part is in a compressed state. When the external force is removed, the elastic piece drives the sliding part to move towards the top of the sleeve 9101 under the action of the elastic restoring force, so that the swing rod 9102 can drive the cloth mechanism 80 to move from the avoiding position to the cloth position.
