The scraping and smearing mechanism 1 of the device is adaptive to the width of a wall surface, one wall is scraped and smeared at a time, and the thickness and the size of single-time scraping and smearing putty are small; the wall surface is scraped from bottom to top, and when the scraping mechanism 1 moves to the upper part of the wall surface, putty below the wall surface tends to be in a dry state; after the wall surface is dried, carrying out secondary scraping, tertiary scraping and even multiple scraping; the putty scraping amount is small, the scraping times are multiple, the adhesion between each layer of putty is tight, the internal moisture is volatilized, the strength is greatly improved, the falling probability of the follow-up wall surface putty is greatly reduced, and the construction quality is improved. Due to the fact that the whole wall is scraped, the whole putty surface is high in flatness, even subsequent polishing and grinding are not needed, efficiency is greatly improved, and construction period is shortened.
Further, the support mechanism 3 includes a base 31 and two sets of support members 32 arranged parallel to each other: the support member 32 includes:
a driving shaft 321 vertically arranged and rotatably mounted on the base 31;
a driving motor 322, the rotating shaft of which is coaxially connected with the driving shaft 321 and is installed on the base 31;
the driving block 323 is sleeved on the driving shaft 321 through the opening and is in threaded connection with the driving shaft 321;

wherein, the automatic feeding mechanism 2 is connected with a driving block 323; the top mount 324 is adapted to abut the ceiling.
The device is erected beside the wall surface through the base 31, and is fixed by using the top seat 324 to prop up the ceiling. The driving motor 322 rotates to drive the driving shaft 321 to rotate, the driving block 323 in threaded connection with the driving shaft 321 moves up and down in the vertical direction, and then the automatic feeding mechanism 2 is driven to move up and down, and the scraping and smearing mechanism 1 connected to the automatic feeding mechanism 2 moves up and down to scrape and smear putty. The base 31 is mounted on a mobile cart or crawler. The top base 324 can be adjusted in length in the vertical direction.
Further, the automatic feed mechanism 2 is provided with two corresponding to the support members 32; the automatic feed mechanism 2 includes:
the positioning block 21 is sleeved on the driving shaft 321 through an opening in a sliding manner;
two ends of the local displacement control structure 22 are respectively connected with the driving block 323 and the positioning block 21, so that the distance between the driving block 323 and the positioning block 21 can be changed while the driving block 323 and the positioning block 21 are kept connected;
a feeding block 23, which is connected with the driving block 323 in a sliding way, and the other end of the feeding block is connected with the wiping mechanism 1;
wherein, the positioning blocks 21 in the two automatic feeding mechanisms 2 are connected through a connecting rod 4; the positioning block 21 is provided with a cooperation structure 24, and the feeding block 23 is provided with a feeding component 25 matched with the cooperation structure 24; when the feeding block 23 approaches the positioning block 21, the positioning block 21 drives the feeding member 25 to move through the cooperation structure 24 so as to slide the feeding block 23.
By connecting the two positioning blocks 21 together by the connecting rod 4, the two positioning blocks 21 can only slide up and down along the driving shaft 321; the local displacement control structure 22 prevents the positioning block 21 and the driving block 323 from being separated from each other, and the distance between the positioning block 21 and the driving block 323 changes. The driving block 323 is connected by the automatic feeding mechanism 2, and the two automatic feeding mechanisms 2 are connected by the wiping mechanism 1, so that the driving block 323 can not rotate and can only be driven by the driving shaft 321 to move up and down. When the driving shaft 321 makes the driving block 323 move downwards, and the positioning block 21 abuts against the base 31 before the driving block 323, the positioning block 21 cannot move downwards, and the driving block 323 is close to the positioning block 21 to drive the feeding block 23 to be close to the positioning block 21; the feeding member 25 moves on the cooperative structure 24 and displaces in the horizontal direction, so that the feeding block 23 displaces and further drives the scraping mechanism 1 to move, the scraping mechanism 1 is far away from the wall surface, and the next time of scraping putty is facilitated.
Further, the local displacement control structure 22 includes:
a plurality of levers 221 provided; one end of the positioning block 21 is connected with the upper end of the positioning block, and the other end of the positioning block is connected with a limiting block 222;
a plurality of limiting holes 325 are formed in the lower end face of the driving block 323, and an inward-contracting baffle ring 326 is arranged at an orifice of each limiting hole 325; the control rod 221 passes through the corresponding stop ring 326, and the limit block 222 is located in the limit hole 325 and abuts against the stop ring 326.
The limiting hole 325 is arranged in the vertical direction; the driving block 323 only moves vertically relative to the positioning block 21 and has a limited movement distance. When the driving block 323 is close to the positioning block 21, the control rod 221 drives the limiting block 222 to slide in the limiting hole 325.
Further, the feeding member 25 includes a feeding bent bar 251 connected to a lower end of the feeding block 23; an elastically telescopic guide rod 252 is arranged at the end part of the feeding bent rod 251;
the cooperation structure 24 comprises a plurality of groups of displacement grooves 241 and a guide groove 242 which are arranged on the inner side of the positioning block 21 and are sequentially communicated end to end; the end of the guide rod 252 is located in the displacement groove 241 or the guide groove 242;
the displacement groove 241 includes a vertical groove 241a vertically arranged and an inclined groove 241b communicating with a top end of the vertical groove 241a and obliquely arranged; a non-return step 241c for preventing the back-off is arranged at the junction of the vertical groove 241a and the oblique groove 241 b; the other end of the oblique groove 241b, which is far away from the vertical groove 241a, is communicated with the bottom end of the vertical groove 241a of the other group of displacement grooves 241, and a non-return step 241c is arranged at the junction of the oblique groove 241b and the vertical groove 241 a;
two ends of the guide groove 242 are respectively communicated with the inclined grooves 241b and the vertical grooves 241a at the two ends of the outer side of the plurality of sets of displacement grooves 241, and a non-return step 241c is arranged at the boundary of the guide groove 242 and the vertical grooves 241 a.
The displacement groove 241 and the guide groove 242 function to guide the movement of the feeding bent bar 251 in a specific manner: after the positioning block 21 is abutted against the base 31 and stops moving downwards; in the process that the driving block 323 drives the feeding block 23 to move downwards continuously, the guide rod on the feeding bent rod 251 is initially positioned at the top end of the vertical rod, the guide rod 252 abuts against the non-return step 241c, and the guide rod 252 is limited from moving downwards along the vertical rod and only enters the inclined groove 241b along the non-return step 241c until sliding into the bottom end of the other vertical groove 241 a; the movement from one vertical groove 241a to the other vertical groove 241a causes a horizontal displacement of the feed rod 251, so that the feed block 23 also performs a horizontal displacement, enabling the wiping mechanism 1 to be retracted relative to the wall surface. It should be noted that the bottom surfaces of the displacement groove 241 and the guide groove 242 are arranged obliquely because a plurality of check steps 241c are required, and the provision of the check steps 241c is necessarily accompanied by the reduction in height of the adjacent grooves, and is required in order for the displacement groove 241 and the guide groove 242 to form one closed groove. When the guide rod 252 finally runs into the guide groove 242, it may be manually pushed so that the guide rod 252 enters the initial vertical groove 241a, may be pushed with an air cylinder or the like. Further, the inner side of the positioning block 21, that is, the surface of the two automatic feed mechanisms 2 facing the positioning block 21. When the driving block 323 moves upward, the guiding rod 252 slides to the top end of the vertical slot 241a, the driving block 323 moves downward continuously, and after the positioning block 21 abuts against the base 31, the guiding rod 252 moves along the inclined slot 241 b.
Further, a placing hole 253 is formed in one end, away from the feeding block 23, of the feeding bent rod 251, and a placing spring 254 is arranged in the placing hole 253; one end of the guide rod 252 passes through the mouth of the seating hole 253 to abut against the seating spring 254, and the other end of the guide rod 252 abuts against the displacement groove 241 or the guide groove 242.
The inclined arrangement of the bottom surfaces of the displacement groove 241 and the guide groove 242 and the setting of the check step 241c require the guide rod 252 to be able to extend and contract, and also require the guide rod 252 to be always located in the displacement groove 241 or the guide groove 242 to drive the feeding block 23.
Furthermore, the feeding block 23 is provided with a through abdicating hole 231; the driving block 323 is positioned in the abdicating hole 231; a horizontal sliding strip 232 is arranged on the inner wall of the abdicating hole 231; a sliding groove 327 in sliding fit with the sliding bar 232 is arranged on the outer wall of the driving block 323 corresponding to the sliding bar 232;
a strip-shaped hole 233 is formed in one surface of the feeding block 23 facing the wiping mechanism 1;
the automatic feed mechanism 2 further includes:
a first speed change gear 26 rotatably installed in the strip hole 233;
a second speed change gear 27 coaxially and fixedly connected to the first speed change gear 26;
a third steering gear 28 rotatably mounted in the strip-shaped hole 233 and engaged with the second speed-change gear 27;
wherein, one side of the driving block 323 facing the first change gear 26 is provided with a rack, and the first change gear 26 is engaged with the rack on the driving block 323; the end part of the scraping mechanism 1 is connected in the strip-shaped hole 233 in a sliding way; the end part of the scraping mechanism 1 is provided with a rack; the rack of the wiping mechanism 1 is engaged with a third steering gear 28. The strip-shaped hole 233 faces the opening of the wiping mechanism 1 and is provided with a boss for supporting the wiping mechanism 1.
The sliding bar 232 and the sliding groove 327 may be added in multiple numbers to ensure the stability of the device. The relief hole 231 is large enough for the feed block 23 to be water-smooth relative to the drive block 323. The upper and lower inner walls of the strip-shaped hole 233 are provided with guide rails, and the end of the wiping mechanism 1 is provided with a sliding groove which is in sliding fit with the guide rails. The second speed change gear 27 has a smaller diameter than the first speed change gear 26. The third steering gear 28 is located between the second speed change gear 27 and the wiping mechanism 1. When the feeding block 23 slides relative to the driving block 323, the first speed changing gear 26 is engaged with the rack on the driving block 323, so that the first speed changing gear 26 rotates, and at the same time, the second speed changing gear 27 and the third steering gear 28 are driven to rotate, and the wiping mechanism 1 is driven to slide. The main reasons for the above settings are: when the feeding block 23 is driven to retreat and drive the wiping mechanism 1 to move away from the wall surface, the feeding amount is larger, namely the distance between the wiping mechanism 1 and the wall surface is the distance between the two vertical grooves 241 a; it can be known that the device faces to the whole wall, the whole device is large, although the weight of the wiping mechanism 1 is greatly reduced by the arrangement of the device (ensuring that the device is light enough to promote the up-and-down movement efficiency and stability, and reduce the power consumption), the guide rod 252 cannot be too small (for example, the diameter is only a few millimeters) to drive the wiping mechanism 1 to horizontally displace, in order to keep the device durable, the guide rod 252 has a large size, the width of the corresponding vertical groove 241a is wide, the distance between the two vertical grooves 241a is inevitably not small, and the wall surface is used for scraping putty, the scraping withdrawal feeding amount between the putty at two sides is usually controlled subtly at 1 millimeter or a few tenths of millimeters, so that the movement of the feeding block 23 needs to be corrected, the combination of a plurality of gears can realize that the wiping mechanism 1 is close to the wall surface every time when the feeding block 23 drives the wiping mechanism 1 to withdraw, the feed amount of the withdrawing is reduced, and the scraping and wiping mechanism 1 is ensured to relatively prevent the withdrawing of an extremely small size every time.
Further, the wiping mechanism 1 includes:
the two ends of the scraping support plate 11 are respectively and slidably arranged in the strip-shaped holes 233, and racks at the two ends of the scraping support plate are respectively meshed with the third steering gear 28;
the scraping box body 12 is connected with the scraping support plate 11 and is provided with a strip-shaped outlet 13;
wherein a scraper 14 extends outwardly from a strip outlet 13 of the scraping box 12.
The scraping box body 12 is arranged between the whole device and the wall surface, the scraping box body 12 is arranged in a slightly inclined way, and the scraping box body 12 is connected with a communicating pipeline which is externally connected with a pump for pumping putty. The scraping box body 12 is used for temporarily storing putty and sending the putty into the scraping box body along with continuous pumping of the putty, the putty is extruded from the strip-shaped outlet 13 and spreads on the scraper 14, and the scraper 14 scrapes the wall surface from bottom to top. It should be noted that the screed 14 is spaced slightly from the wall surface to facilitate putty filling.
