wherein, the positioning blocks 21 in the two automatic feeding mechanisms 2 are connected through the connecting rod 4; the positioning block 21 is provided with a cooperative structure 24, and the feeding block 23 is provided with a feeding member 25 matched with the cooperative 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 cooperative structure 24 so as to slide the feeding block 23.

By connecting the two positioning blocks 21 together with 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 is changed. The driving block 323 is connected by the automatic feeding mechanism 2, and the two automatic feeding mechanisms 2 are connected by the scraping mechanism 1, so that the driving block 323 can not rotate either 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 is propped against the base 31 before the driving block 323, the positioning block 21 cannot move downwards, the driving block 323 is close to the positioning block 21, and the feeding block 23 is driven to be close to the positioning block 21; the feeding member 25 moves on the cooperative structure 24 and moves in the horizontal direction, so that the feeding block 23 moves to drive the scraping mechanism 1 to move, and the scraping mechanism 1 is far away from the wall surface, so that putty can be scraped next time.

Further, the local displacement control structure 22 includes:

a control lever 221 provided with a plurality of levers; one end is connected with the upper end of the positioning block 21, and the other end is connected with a limiting block 222;

wherein, a plurality of limit holes 325 are arranged on the lower end surface of the driving block 323, and the orifice of each limit hole 325 is provided with a stop ring 326 which contracts inwards; the control rod 221 passes through the corresponding baffle ring 326, and the limiting block 222 is positioned in the limiting hole 325 and abuts against the baffle ring 326.

the cooperative 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 communicated end to end in sequence; 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; an anti-rollback check step 241c is arranged at the juncture of the vertical groove 241a and the inclined groove 241b; the other end of the inclined groove 241b 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 inclined groove 241b and the vertical groove 241 a;

both ends of the guide groove 242 are respectively communicated with the inclined grooves 241b and the vertical grooves 241a at both ends of the outer side of the plurality of groups of displacement grooves 241, and a non-return step 241c is arranged at the juncture 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 feed bar 251 in such a way that: 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, the guide rod on the feeding bent rod 251 is initially positioned at the top end of the vertical rod, the guide rod 252 is propped against the non-return step 241c, the guide rod 252 is limited to be unable to move downwards along the vertical rod, and only can enter 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 of one vertical groove 241a to the other vertical groove 241a causes the horizontal displacement of the feeding bent rod 251, so that the feeding block 23 also performs the horizontal displacement, and the back-up of the scraping mechanism 1 relative to the wall surface is realized. It is to be noted that the bottom surfaces of the displacement groove 241 and the guide groove 242 are obliquely arranged because a plurality of check steps 241c are required, and the arrangement of the check steps 241c is necessarily accompanied by a decrease in the height of the adjacent grooves, which is required in order for the displacement groove 241 and the guide groove 242 to form one closed groove. When the guide bar 252 finally runs into the guide groove 242, it may be manually pushed so that the guide bar 252 enters the first vertical groove 241a, or may be pushed with a cylinder or the like. The inner side of the positioning block 21, that is, the side of the two automatic feeding mechanisms 2 opposite to the positioning block 21. The driving block 323 moves upwards, the guide rod 252 slides to the top end of the vertical groove 241a, the driving block 323 continuously moves downwards, and after the positioning block 21 abuts against the base 31, the guide rod 252 moves along the inclined groove 241 b.

Further, a positioning hole 253 is formed at one end of the feeding bent rod 251, which is far away from the feeding block 23, and a positioning spring 254 is arranged in the positioning hole 253; one end of the guide rod 252 passes through the mouth of the placement hole 253 to abut against the placement 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 that the guide rod 252 be telescopic, and also ensure that the guide rod 252 is always positioned in the displacement groove 241 or the guide groove 242 to realize driving of the feed block 23.

Further, the feeding block 23 is provided with a through abdication hole 231; the driving block 323 is positioned in the abdication hole 231; a horizontal sliding bar 232 is arranged on the inner wall of the abdication hole 231; a sliding groove 327 which is in sliding fit with the sliding bar 232 is arranged on the outer wall of the driving block 323 and corresponds to the sliding bar;

a strip-shaped hole 233 is formed in one surface of the feeding block 23 facing the scraping mechanism 1;

the automatic feeding mechanism 2 further includes:

a first speed change gear 26 rotatably installed in the bar-shaped hole 233;

a second speed change gear 27 coaxially fixedly connected to the first speed change gear 26;

a third steering gear 28 rotatably installed in the bar-shaped hole 233 to be engaged with the second speed change gear 27;

wherein, one surface of the driving block 323 facing the first speed change gear 26 is provided with a rack, and the first speed change gear 26 is meshed 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 wiper mechanism 1 meshes with the third steering gear 28. The opening of the strip-shaped hole 233 facing the wiper mechanism 1 is provided with a boss for supporting the wiper mechanism 1.

The sliding bar 232 and the sliding groove 327 can be added with a plurality of sliding bars to ensure the stability of the device. The relief holes 231 are large enough to allow the feed block 23 to be smoothed relative to the drive block 323. The inner walls of the upper side and the lower side of the strip-shaped hole 233 are provided with guide rails, and the end part of the scraping mechanism 1 is provided with a sliding groove which is in sliding fit with the guide rails. The second ratio gear 27 has a smaller diameter than the first ratio gear 26. The third steering gear 28 is located between the second change gear 27 and the wiper mechanism 1. When the feeding block 23 slides relative to the driving block 323, the first speed-changing gear 26 is meshed with the rack on the driving block 323, so that the first speed-changing gear 26 rotates, and simultaneously drives the second speed-changing gear 27 and the third steering gear 28 to rotate, so as to drive the scraping mechanism 1 to slide. The main reason for the above arrangement is that: each time the feeding block 23 is driven to retract to drive the scraping mechanism 1 to be far away from the wall surface, the feeding amount is relatively large, namely the distance of the scraping mechanism 1 to be far away from the wall surface is the distance between the two vertical grooves 241 a; it can be appreciated that the present device faces the whole wall, the whole device is relatively large, although the device is provided with the device to greatly reduce the weight of the scraping mechanism 1 (ensuring that the device is light enough to promote the up-down movement efficiency and stability thereof and reduce the power consumption), the scraping mechanism 1 is required to be driven to horizontally displace, the guide rod 252 cannot be too small in size (for example, the diameter is only a few millimeters), in order to keep the device durable, the guide rod 252 is relatively large in size, the corresponding vertical groove 241a is relatively wide, the distance between the two vertical grooves 241a is necessarily not small, the wall surface is scraped, the scraping and backing feed amount between the putty on two sides is controlled slightly, usually at 1 millimeter or a few tenths of millimeters, so that the movement of the feed block 23 needs to be corrected, the combination of a plurality of gears can realize that the scraping mechanism 1 is relatively close to the wall surface when the feed block 23 drives the scraping mechanism 1, the backing feed amount is reduced, and the backing feed amount of the scraping mechanism 1 is ensured to be relatively limited to be prevented from backing.

Further, the wiping mechanism 1 includes:

the scraping support plate 11 is respectively and slidably arranged in the strip-shaped holes 233 at two ends, and racks at two ends of the scraping support plate are respectively meshed with the third steering gear 28;

wherein the strip-shaped outlet 13 of the scraping box body 12 is outwardly extended with a scraper 14.

The scraping box body 12 is positioned between the whole device and the wall surface, the scraping box body 12 is arranged in a slight inclination, and the scraping box body 12 is connected with a communication pipeline which is externally connected with a pump for pumping putty. The scraping box body 12 is used for temporarily storing the putty, and is pumped into the scraping box body along with the continuous pumping of the putty, the putty is extruded from the strip-shaped outlet 13 and is spread on the scraping plate 14, and the scraping plate 14 scrapes the putty on the wall surface from bottom to top. It should be noted that the squeegee 14 is slightly spaced from the wall surface to facilitate putty filling. Once the putty is stopped from being pumped into the scraping box body 12, the putty cannot flow out from the strip-shaped outlet 13 due to the internal pressure, so that the excessive putty falls off from the scraping plate 14 when the scraping mechanism 1 moves downwards (even if a small amount of putty is smeared on a wall surface, the large bureau is not influenced, the subsequent scraping and coating can be performed for the second time, the top of the wall surface is smeared for the last time, and the base 31 moves backwards to prevent the redundant putty from adhering).

Further, the top base 324 includes: a top plate 324a; a sleeve 324b, one end of which is closed, sleeved on the end of the driving shaft 321 and connected with the driving shaft 321 through a bearing; the opposite pull shafts 324c are provided with two opposite pull shafts, and two support shafts 324d are respectively hinged at two ends of the opposite pull shafts;

of the four support shafts 324d hinged to the ends of each pair of pull shafts 324c, two of the support shafts 324d have ends hinged to the top plate 324a, and the other two support shafts 324d have ends hinged to the closed ends of the sleeves 324 b; the middle parts of the two opposite-pulling shafts 324c are respectively provided with opposite-pulling threaded holes; a pair of pull rods 324e are connected in the two pair of pull threaded holes in a threaded manner; the threads in the two opposite-pulling threaded holes are opposite in rotation direction.

By rotating the opposite pull rod 324e, the two opposite pull shafts 324c are moved toward or away from each other to drive the top plate 324a to rise or fall, thereby realizing the abutment of the top plate 324a against the ceiling, and fixing the device. The two top plates 324a are connected through the connecting rod 4, so that stability is improved.
