Detailed Description

The invention relates to a cement mortar scraping device of a scraping robot, which is arranged at the front end of a front extending arm 4 of a lifting frame 1 moving in the vertical direction and specifically comprises a calender plate 2 and a slurry supplementing groove 6, as shown in a side view of figure 1. Calender plate 2 and wall cement mortar layer contact, establish vibrating machine and multiunit connecting plate on calender plate 2 trailing flank, the front end of protracting arm 4 articulates and sets up on the connecting plate.

Calender plate 2 is the horizontal strip shaped plate that sets up, and calender plate 2 is smooth with wall cement mortar contact surface, and calender plate 2 rear portion upper end is for mending dressing trough 6, mends dressing trough 6 and is the top opening towards the wall, mends the dressing trough and establishes the sealing member with calender plate top edge hinged position.

The rear part of the slurry supplementing groove 6 is hinged with a press polish connecting rod 7, the swinging rod 3 is in an inclined state that the rear end is higher than the front end, the rear end of the press polish connecting rod 7 is hinged with the swinging rod 3, the middle part of the swinging rod 3 is hinged with the lifting frame, and the hinged position between the swinging rod 3 and the lifting frame is located at the position close to the front part of the middle part. The rear end of the swinging rod 3 is provided with a rear pressing wheel, and the rear part of the calender plate 2 is provided with a spring for supporting the upper edge of the calender plate to incline backwards.

The back pinch roller of the swing lever 3 rear end is pushed down the back front end perk and is pushed the press polish connecting rod 7 forward, the press polish connecting rod 7 that pushes forward promotes the press polish board 2 upper portion that articulates at the proud arm 4 and inclines forward and contact with wall cement mortar layer.

The swing rod 3 and the press polish connecting rod 7 are two groups, the swing range of the swing rod 3 is positioned at two sides of the front part of the lifting frame, the lower part of the rear end of the swing rod 3 is provided with a limiting rod 8, the limiting rod 8 is arranged at the upper part of the front end of the lifting frame in a protruding mode, and the limiting rod 8 limits the downward swing range of the rear end of the swing rod 3. The rear part of the slurry supplementing groove 6 is provided with a water supplementing tank 9, and the water supplementing tank 9 is fixed at the side position of the front section of the lifting frame.

One side tip of calender plate sets up links up shovel 10, links up the articulated tip that sets up at the calender plate of shovel 10, links up 10 lower limb of shovel for the arc of indent, and outstanding cement mortar on the wall cement mortar layer is eradicateed when the arc limit conveniently links up shovel 10 and calender plate and is in the coplanar. A screw shaft is arranged in the slurry supplementing groove 6, uniformly distributed screw blades are arranged on the screw shaft 7, and a screw motor for driving the screw shaft to rotate is arranged on one side of the rear side of the slurry supplementing groove.

The working process of the device is as follows: the lifting frame drives the device to move upwards, the polishing plate contacts the mortar layer of the wall surface, and the surface of the mortar layer is leveled into a polished surface. When the wall surface mortar is too thick, the top of the polishing plate scrapes off the too thick mortar, and the redundant mortar enters the mortar supplementing groove. And when the screw shaft 8 rotates, the screw blades push the mortar from one side to the other side, and the positions of the mortar in the mortar supplementing groove are at the same height in the process. For a location where the thickness of the mortar is insufficient, the mortar in an overfilled state may overflow the calender plates and be replenished to the location. And the engaging shovel 10 at one end of the calender plate shovels the adjacent cement mortar protruded portion. When the mortar in the mortar supplementing groove is too much, the screw shaft rotates at the moment, and the screw blades push the mortar to one side of the discharge port and discharge the mortar, so that the mortar height can be controlled within a reasonable range, and the mortar in the sand well groove is controlled in an overflowing state.

When the device runs to the top wall surface, the rear pressing wheel at the rear end of the swinging rod contacts the top wall surface, the device continues to run upwards, the rear pressing wheel drives the rear end of the swinging rod to swing downwards, the swinging rod drives the calendaring connecting rod to push forwards, the calendaring connecting rod pushes the upper end of the calendaring plate to contact with wall cement mortar forwards, the device runs to the highest position, the device moves downwards, the lower end of the calendaring plate is separated from the wall surface, and the edge of the upper end of the calendaring plate carries out downward calendaring operation on the wall cement mortar.

The device can realize the scraping matte treatment of the cement mortar on the wall surface, thereby improving the working efficiency of the construction step and improving the quality stability; can replace manual construction, reduce the requirement of workers on the technology and reduce the construction cost. Compared with the patent of 'construction flat robot slurry-supplementing and strickling-off device' (patent number CN 201721299954.2) applied by the applicant, the mechanical structure is simpler, and the complexity and the failure rate are reduced.
