In combination with the above, the mortar paving machine in the embodiment of the present invention is implemented by combining the processes, that is, only one area of the building floor surface corresponding to the external shape can be covered by one cycle of the paving mechanism 310, and then the areas are connected by multiple cycles to finally cover the whole building floor surface. In this process, it can be understood that it is not guaranteed that the last remaining area is exactly adapted to the size of laying mechanism 310, for which purpose an "effective laying mechanism" adapted to the remaining area can be adjusted by the combination of baffle 3444 and the feed opening, from which "effective laying mechanism" the mortar falling off can exactly fill the remaining area.

Specifically, in order to more clearly understand the working process of the mortar laying machine, the length, width and height of the main body frame 100 are 700mm, the total length of the laying mechanism 310 is 700mm, the laying mechanism 310 is exposed 600mm after extending out, the total width of the laying mechanism 310 is 100mm, the total number of the laying mechanism 310 is 10, the total height of the laying mechanism 310 is 12mm, the thickness of the grid plate 311 is 1.6mm, and the bottom of the supporting plate 312 is 10mm away from the ground. After the paving mechanism 310 is filled with mortar, the filled mortar is paved on the ground just enough to form a mortar layer with the thickness of 10mm in an area of 600mm multiplied by 100 mm. Assuming that the laying operation starts from right to left and from the corner (moving in the first direction), the area of each laying is 600mm x 100mm, the small area laid each time is seamlessly jointed with the previous small area to form a mortar layer belt with the width of 600mm, and when the length of the mortar layer belt reaches half of the width of a room, the construction is suspended. Then the whole machine is translated to the leftmost side of the room, construction is started from left to right until the laid mortar layer is butted with the previously laid mortar layer belt, when the mortar layer belt is butted from left to right, the width of the last residual area at the joint is generally not exactly 100mm, the width of the residual area at the joint needs to be measured in advance, then a plurality of baffles 3444 are manually or pneumatically inserted (closed), so that only the mortar falls off from the grids in the grating plates 311 corresponding to the width of the residual area, then the equipment is still laid in the previous action mode, and construction is suspended after the laying at the joint is finished.

Thereafter the machine is translated backwards (in a second direction) by the length of the laying mechanism 310, and the above construction operations from right to left and then from left to right are repeated to complete the remaining laying operations.

In one embodiment, the feeding funnel 3443 and the chute square tube 320 are fixed together, for example, they can be fixed together by welding, and the feeding funnel 3443 is provided with a hanging hole 3443b for hanging the chute square tube 320 and the laying mechanism 310 carried by it on the main body frame 100.

The sliding groove square tube 320 and the laying mechanism 310 are hung on the main body frame 100 in a hanging mode, so that the sliding groove square tube 320 and the laying mechanism 310 have a certain vertical swinging space, and the supporting plate can apply proper pressure to the surface of mortar.

In one embodiment, paving device 300 further includes a counter balance mechanism 350, where counter balance mechanism 350 is configured to allow the upper surface of paving mechanism 310 to be snug against the feed opening without generating unnecessary friction.

After the laying mechanism 310 is tightly attached to the feed opening, slurry leakage or uneven laying thickness can be prevented, but when the laying mechanism 310 almost completely extends out of the sliding groove square tube 320, the laying mechanism 310 filled with mortar has to have a large elastic force to press the elastic member 351 to possibly tightly attach the laying mechanism 310 to the feed opening due to the lever effect, and the large elastic force of the elastic member 351 can greatly increase the friction force between the 310 and the 320. The balancing mechanism 350 eliminates this leverage and makes it possible to use a low-spring force against the elastic member 351, thereby greatly reducing the friction force of the laying mechanism 310 during its movement in the chute square 320.

Further, in an embodiment, referring to fig. 3-4, the balancing mechanism 350 includes a pressing elastic member 351 for pressing the laying mechanism 310 toward the discharging opening.

It can be understood that when the laying mechanism 310 extends out of the chute square tube 320 for a long time, the pressing elastic member 351 needs to have sufficient rigidity, otherwise it is difficult to exert its function, and when the rigidity is too high, it is necessary to make the laying mechanism 310 generate a larger friction force during the moving process, which not only needs to make the chute driving motor 331 work with a higher power, and increase the energy consumption, but also easily causes the problem of shortening the service life of the device.

To this end, in an embodiment, the balancing mechanism 350 further includes a balancing rod 352 connected to the feeding hopper 3443, a balancing weight 353 movably disposed on the balancing rod 352, and a telescopic elastic member 354 connected between the feeding hopper 3443 and the balancing weight 353, a bottom of the balancing weight 353 is provided with a snap 3531, an end of the grating plate 312 is provided with a snap 3123, and when the grating plate 311 moves out of the sliding slot, the snap 3531 snaps into the snap 3123 to drive the balancing weight 353 to move along with the grating plate 311.

At this time, it can be known that, as the balance weight 353 moves along with the grid plate 311, the balance weight 353 can be buckled with the bayonet 3123 at the end of the grid plate through the buckle 3531 when the laying mechanism 310 slides out of the sliding groove square tube 320, so as to restrain the laying mechanism 310. When the laying mechanism 310 extends out of the sliding groove square tube 320 for a long time, the whole laying device can rotate anticlockwise by taking the hanging hole 3443b as an axis, so that the end part of the laying mechanism 310 swings downwards, the buckle 3531 applies an upward balanced pulling force to the bayonet 3123, the rigidity requirement of the abutting elastic piece 351 can be reduced to a certain extent, and the purposes of reducing energy consumption and prolonging the service life of equipment are achieved.

In one embodiment, a weight 355 is disposed at one end of the chute square 320, the position of the weight 355 can be adjusted relative to the chute square 320, and the position-adjustable weight 355 is used to adjust the moment at one end of the chute square 320 to adjust the force exerted by the pallet 312 on the mortar falling on the building floor surface during plastering.

The counterweight 355 is disposed at two ends of the chute square tube 320 opposite to the feeding hopper 3443, and when the mortar spreader is used for the first time, the mortar falls completely from the paving mechanism 310 and the supporting plate 312 is reset below the grating plate 311, the counterweight 355 enables the supporting plate 312 to have an upward elevation angle, thereby preventing the mortar layer which is not yet plastered from being damaged. When the mechanism 310 filled with mortar is extended again, the plate 312 is moved downwards by adjusting the weight 355 and lightly presses on the falling mortar, and then the pressure applied to the mortar layer can be changed by continuously adjusting the weight 355, so as to lay out a mortar layer with more uniform thickness.

In an embodiment, referring to fig. 4, a mortar scraper 360 is further disposed at the bottom of the chute square tube 320 for timely scraping off mortar adhered to the lower surface of the supporting plate 312, so that each laying operation of the laying mechanism 310 can be performed with high quality.
