[0002] Plaster coating is a traditional surface treatment for homes. It involves applying mortar to surfaces such as walls, floors, and ceilings under construction. This process not only protects structures from damage from wind, rain, and snow, but also enhances the surface's waterproofing, weathering resistance, and thermal insulation. Furthermore, it improves both aesthetics and living comfort, making it widely used in the renovation industry.

[0003] At present, most wall plastering work is still done manually. Although some plastering equipment can complete basic plastering tasks during the wall construction process, the pressure between the scraper of the plastering equipment and the wall is usually fixed during the construction process, and some depressions on the wall cannot be filled in time, which easily leads to the defect of uneven plaster layer. Therefore, the market urgently needs a plastering device for construction to solve the above problems. Summary of the Invention

[0006] The U-shaped limit switch is fixedly connected to the adjusting handle, and the U-shaped limit switch is provided with three groups of limit switch through holes, and the limit switch body is arranged in one of the limit switch through holes. In addition, by arranging the limit U-shaped limit switch, the limit switch through holes and the limit switch body, when the limit switch body is pulled out of the limit switch through holes, the two groups of adjustment handles can be staggered and separated from each other, thereby realizing the function of the two groups of adjustment handles driving the bipolar permanent magnets to rotate to different angles respectively, and because the front scraper plate and the rear scraper plate are hinged, the front and rear pressing forces of the scraper plate during plastering are loosened and tightened, which further improves the quality of plastering.

The locking return spring is arranged between the two groups of guide limit ears, and the separation of the locking column and the locking gear disk can be controlled by the locking drive block, and then the bipolar permanent magnet is driven to rotate by the adjusting handle. As the bipolar permanent magnet is misaligned and separated from the S-pole permanent magnets at both ends, the force of the S-pole permanent magnet pulling the front scraper plate and the rear scraper plate through the damping spring gradually decreases, thereby achieving the technical effect of adjustable compression during the plastering process of the scraper plate.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] (1) In order to solve the problem that the degree of pressure between the scraper of the plastering equipment and the wall is usually fixed during the construction process, and the function of timely filling grouting cannot be achieved for certain concave parts of the wall, which easily leads to uneven plastering layer, the present invention provides a plastering adjustment mechanism and a plastering scraper mechanism, which not only realizes the function of adjustable pressure of the scraper during plastering, but also the pressing force of the front and rear scrapers can be kept synchronous or loose in front and tight in the back, thereby achieving a better plastering effect, and by providing a slurry pushing component, it is further possible to timely fill grouting certain concave parts of the wall, thereby fully overcoming the defect of uneven plastering layer;

[0016] (2) wherein, through the magnet rotation drive assembly, the scraper opening assembly, the slurry pushing assembly and the locking assembly, the bipolar permanent magnet can generate magnetic attraction to the S-pole permanent magnets at both ends thereof, and then the S-pole permanent magnet pulls the front slurry scraper and the rear slurry scraper toward the upper plastering frame body through the damping spring, and the two symmetrically arranged groups of front slurry scrapers and rear slurry scrapers can scrape the slurry on both sides of the wall at the lower part of the upper plastering frame body, and the locking drive block can control the separation of the locking column and the locking gear disc, and then the bipolar permanent magnet is driven to rotate by the adjusting handle, and as the bipolar permanent magnet is dislocated and separated from the S-pole permanent magnets at both ends thereof, the force of the S-pole permanent magnet pulling the front slurry scraper and the rear slurry scraper through the damping spring gradually decreases, thereby achieving the technical effect of adjustable compression during the plastering process of the scraper;

In order to solve the problem that during the construction process, the pressure between the scraper of the plastering equipment and the wall is usually fixed, and it is impossible to timely fill the grouting function for certain recessed parts of the wall, which easily leads to an uneven plaster layer, the present invention sets a plastering adjustment mechanism 1 and a plastering scraper mechanism 2, which not only realizes the function of adjustable pressure of the scraper during plastering, but also the pressing force of the front and rear scrapers 215 can be kept synchronized or loosened in front and tightened in the back, thereby achieving a better plastering effect, and by setting a slurry pushing component, certain recessed parts of the wall can be filled with grout in time, thereby fully overcoming the defect of uneven plaster layer.

[0035] Among them, the magnet rotation drive assembly includes an adjustment handle 100, a limiting U-shaped block 101, a limiting column body 103, a driving shaft 105, a driving gear 106, a driven gear 107, a driven shaft 108, a bipolar permanent magnet 109, an S-pole permanent magnet 110 and a damping spring 111.

In addition, by setting the limit U-shaped block 101, the limit column through hole 102 and the limit column body 103, when the limit column body 103 is pulled out from the limit column through hole 102, the two groups of adjustment handles 100 can be staggered and separated from each other, thereby realizing the function of the two groups of adjustment handles 100 respectively driving the bipolar permanent magnet 109 to rotate to different angles, and because the front scraper plate 212 and the rear scraper plate 215 are hinged, the front and rear pressing force of the scraper plate during plastering is loosened in front and tightened in the back, further improving the quality of plastering.

[0037] In addition, the plastering scraper mechanism 2 includes an upper plastering frame body 200, an axle rod limiting ear 201 and a locking toothed disc 202. The upper plastering frame body 200 is provided with a permanent magnet mounting groove 203, a permanent magnet inner slide groove 204, an axle rod rotation groove 205, a mortar filling port 206, a mortar passing groove 207, a lower slurry outlet 208, a guide rod main slide groove 209, a permanent magnet outer slide groove 210 and a push plate side slide groove 211. The axle rod limiting ear 201 is fixedly connected to the upper plastering frame body 200, and the locking toothed disc 202 is fixedly connected to the upper plastering frame body 200. There are four groups of axle rod limiting ears 201. The hinged ear 213 is fixedly connected to the front scraper plate 212. The connecting column 214 passes through the rear scraper plate 215. The front scraper plate 212, the hinged column 214 and the rear scraper plate 215 are each provided with two groups. A slide groove is opened in the middle of one of the adjustment handles 100. The locking drive block 104 is arranged in the slide groove. The guide limit ear 118 is fixedly connected to the inner surface of the adjustment handle 100. The drawing body 116 is arranged on the inner surface of the adjustment handle 100. The two groups of adjustment handles 100 are arranged between the two groups of locking gear discs 202. The lower end of the locking column 117 is engaged with the locking gear disc 202. The two groups of adjustment handles 100 are limited and fixed by the limiting column body 103, and the driving shaft 105 is rotatably connected to the shaft limiting ear 201.

[0038] In this embodiment, the driven shaft 108 is rotatably connected to the shaft rotating groove 205, the bipolar permanent magnet 109 and the driven gear 107 are both arranged in the permanent magnet mounting groove 203, the S-pole permanent magnet 110 and the damping spring 111 are both slidably connected to the permanent magnet inner slide groove 204, one group of damping springs 111 is fixedly connected to the front scraper plate 212, and the other group of damping springs 111 is fixedly connected to the rear scraper plate 215, the main guide rod 112 and the compensation spring 113 are both slidably arranged in the guide rod main slide groove 209, one end of the front main guide rod 112 is hinged to the front scraper plate 212, and one end of the rear main guide rod 112 is hinged to the rear scraper plate 215, both ends of the pusher plate body 114 are slidably arranged in the pusher plate side slide groove 211, and the auxiliary guide rod 11 The upper plastering frame body 200 is penetrated by one set of guiding rods 115, wherein one set of guiding rods 115 is fixedly connected to the front scraping plate 212, and the other set of guiding rods 115 is fixedly connected to the rear scraping plate 215. Furthermore, by providing a pushing assembly, the front scraping plate 212 and the rear scraping plate 215 can be loosened and clamped on the wall by only slightly turning the adjustment handle 100. At the same time, the front scraping plate 212 and the rear scraping plate 215 can drive the pushing plate body 114 to slide along the pushing plate side groove 211 through the guiding rods 115, thereby achieving the technical effect of pushing the mortar in the mortar filling port 206 into the mortar passing groove 207 and the lower mortar outlet 208 by the pushing plate body 114, thereby achieving the function of repairing the wall depression while scraping and plastering, and effectively improving the flatness of the wall.

[0039] When in use, first, press the locking drive block 104, so that the locking drive block 104 drives the wire drawing body 116 to retract, and the two ends of the wire drawing body 116 respectively drive the locking column 117 to overcome the elastic force of the locking return spring 119 and slide upward along the guide limit ear 118, and the locking column 117 will separate from the locking gear disk 202, thereby realizing the unlocking function. Secondly, hold the adjusting handle 100 to rotate the adjusting handle 100, and then the adjusting handle 100 drives the driving shaft 105 to rotate, and the driving shaft 105 will pass The driving gear 106 drives the driven gear 107 to rotate, and the driven gear 107 drives the bipolar permanent magnet 109 to rotate through the driven shaft 108. As the bipolar permanent magnet 109 rotates, the magnetic attraction of the bipolar permanent magnet 109 to the S-pole permanent magnet 110 at both ends gradually weakens, and the pulling force of the S-pole permanent magnet 110 to pull the front scraper 212 and the rear scraper 215 through the damping spring 111 gradually weakens until the bipolar permanent magnet 109 is in a vertical state, and the front scraper 212 and the rear scraper 215 will be in the compensation state. The spring 113 and the main guide rod 112 push the two sides of the upper plastering frame body 200 to separate, and then the front scraper plate 212 and the rear scraper plate 215 can be clamped into the two sides of the wall. The upper plastering frame body 200 is placed on the upper part of the wall to prepare for the next step of scraping and plastering. Then, the locking drive block 104 is pressed again to separate the locking column 117 from the locking gear plate 202, and then the adjusting handle 100 is rotated to reset to the vertical state, and the technical effect of the bipolar permanent magnet 109 attracting the S-pole permanent magnet 110 is achieved again. Then, the S-pole permanent magnet 110 pulls the front scraper 212 and the rear scraper 215 through the damping spring 111 to squeeze the wall surface, loosening the locking drive block 104. The locking column 117 moves downward under the elastic force of the locking return spring 119, and the locking column 117 is clamped with the locking gear plate 202, thereby realizing the locking function. After further mortar is put into the mortar filling port 206, the entire device is slid along the wall by pulling the adjustment handle 100, thereby realizing the function of scraping and plastering the mortar on both sides of the lower wall of the upper plastering frame body 200.

[0040] When a depression appears on the wall surface, the locking drive block 104 is pressed again, and the locking drive block 104 drives the locking column 117 to move along the guide limit ear 118 through the driving gear 106. When the locking column 117 is separated from the locking gear disk 202, the adjusting handle 100 is rotated so that the adjusting handle 100 drives the driving gear 106 to rotate through the driving shaft 105, and then the driven gear 107 drives the bipolar permanent magnet 109 to rotate through the driven shaft 108. When the bipolar permanent magnet 109 is in a vertical state, the magnetic attraction of the bipolar permanent magnet 109 to the S pole permanent magnet 110 gradually weakens until it disappears. The front scraper plate 212 and the rear scraper plate 215 will move away from the upper plastering frame under the action of the main guide rod 112 and the compensation spring 113. The upper plastering frame body 200 slides in the direction of the upper plastering frame 200, and the adjusting handle 100 is held again and rotated to the initial state. At the same time, the bipolar permanent magnet 109 is reset to the initial horizontal state, and the S-pole permanent magnet 110 pulls the front scraper plate 212 and the rear scraper plate 215 close to the upper plastering frame body 200 through the damping spring 111, and then the front scraper plate 212 and the rear scraper plate 215 respectively drive the pushing plate body 114 to slide along the pushing plate side slide groove 211 through the guiding rod 115, so that the pushing plate body 114 pushes the mortar in the mortar filling port 206 into the inner mortar passing groove 207, and squeezes out from the lower slurry outlet 208 and the outer side of the mortar passing groove 207, thereby realizing the function of repairing the wall depression while scraping and plastering, effectively improving the flatness of the wall;

[0041] Finally, the limiting U-shaped blocks 101 on the two sets of adjustment handles 100 are offset, and the limiting column body 103 is inserted into the limiting column through hole 102. The two sets of adjustment handles 100 can respectively drive the driving gear 106 to rotate through the driving shaft 105, and then the driven gear 107 drives the bipolar permanent magnet 109 to rotate at different angles through the driven shaft 108. Since the front and rear sets of bipolar permanent magnets 109 respectively pull the front scraper 212 and the rear scraper 215 through the S-pole permanent magnet 110 and the shock-absorbing spring 111, due to the different pulling forces and the hinged connection between the front scraper 212 and the rear scraper 215, by adjusting the rotation angle of the two sets of adjustment handles 100, the front and rear pressing forces of the scraper can be loosened in the front and tightened in the back during the plastering process, thereby further improving the quality of the plastering.
