One end of each of the two racks 40 is fixedly connected, and a gear 41 is rotatably connected to the middle of the top of the support plate 36. One end of the two racks 40 is meshed with the outer surface of the gear 41. A first motor 42 is fixedly installed on the lower inner wall of the frame 37. The output end of the first motor 42 passes through the support plate 36 and is fixedly connected to one end of the gear 41. The extension plate 31 and the scraper 32 are driven by the gear 41 to move in relative directions under the output of the first motor 42. The connecting plate 39 at one end of the two racks 40 and the slide rail 38 are connected. The two sliders 30 at the top of the support plate 36 perform horizontal and stable linear sliding to ensure the stability of movement. The guide grooves 34 opened on the outer surfaces of the two side plates 33 provide a height change for the movement of the extension plate 31 during the movement, and provide a fixed movement trajectory for the movement of the extension plate 31, thereby helping the extension plate 31 to maintain a parallel state with the scraper 32 during the expansion movement, and can be placed on the bottom end of the scraper 32 along the inclined surface of one end of the scraper 32 when merging, which provides rationality for the movement of the extension plate 31 and the scraper 32.
[0018] The lifting device 2 includes a shell 21, one end of which is provided with a slide groove 22, two guide rods 23 are fixedly connected to the inner walls of both ends of the shell 21, and a screw rod 26 is rotatably connected to the inner walls of both ends of the shell 21. The outer surfaces of the two guide rods 23 are slidably sleeved with a transmission kit 24, and a through-type thread groove 25 is provided on the outer surface of the transmission kit 24. The outer surface of the thread groove 25 is threadedly connected with the outer surface of the screw rod 26. A second motor 27 is fixedly installed on the top of the shell 21, and the output end of the second motor 27 is fixedly connected to one end of the screw rod 26. One end of the transmission kit 24 is fixedly connected to one end of the frame 37. Under the output of the second motor 27, the transmission kit 24 is driven to move up and down by the rotating screw rod 26. The two guide rods 23 provide a stable moving guide for the movement of the transmission kit 24 to prevent the transmission kit 24 from deflecting when moving. One end of the transmission kit 24 passes through the slide groove 22 and is fixedly connected to one end of the frame 37, thereby realizing the lifting and lowering movement of the extension mechanism 3. The operator can perform a scraping and leveling movement on the wall through the lifting and lowering extension mechanism 3.
[0019] One end of the scraper 32 is set with an inclined surface, and the outer surface of the extension plate 31 is slidably fitted with the outer surface of the scraper 32. Connecting pins are fixedly installed on both sides of the bottom end of the extension plate 31. The two connecting pins are interlaced and connected with the outer surface of one of the connecting plates 39. The inclination angle of the inclined surface at one end of the scraper 32 corresponds to the inclination angle of one end of the guide groove 34, which provides a variable movement trajectory for the movement of the extension plate 31, making it convenient for the extension plate 31 to slide along the inclined end of the scraper 32. The function of the two connecting pins is to ensure that the extension plate 31 will not tilt during the change of the movement trajectory, so that the extension plate 31 can change its height.
[0020] The two guide grooves 34 and the two sliding pins 35 are distributed in a mirror image, and the outer surfaces of the two sliding pins 35 are respectively slidably fitted with the outer surfaces of the two guide grooves 34. One end of the two guide grooves 34 is set at an inclined angle. The two sliders 30, the slide rails 38, the connecting plate 39, and the rack 40 are all distributed in a mirror image. The extension plate 31 has the same width as the scraper 32, and the extension plate 31 and the scraper 32 are located in the same plane. Four universal wheels are fixedly connected to the bottom end of the bottom plate 1. The four universal wheels are distributed in a rectangular array. The two guide grooves 34 and the sliding pins 35 distributed in a mirror image provide movement of the extension plate 31. A moving trajectory of the same distance and the same angle is provided, so that the extension plate 31 changes from a straight-line movement to a continuously rising or falling movement process during the movement. The mirror-distributed slider 30, slide rail 38, connecting plate 39, and rack 40 synchronously drive the extension plate 31 and the scraper 32 to move in relative directions under the rotation of the gear 41, ensuring that the two connecting plates 39 remain stable during movement. The extension plate 31 and the scraper 32 have the same width to ensure that the scraping process can be smoother and smoother. The four universal wheels at the bottom end of the base plate 1 are for the convenience of the operator to move.
[0021] The transmission kit 24 is in the shape of an "I" character, one end of the transmission kit 24 passes through the slide groove 22, and the outer surface of the transmission kit 24 slides and fits with the outer surface of the slide groove 22. One end of the transmission kit 24 in the shape of an "I" character extends outward and passes through the slide groove 22, which helps the transmission kit 24 to better fit the outer surface of the slide groove 22 during movement, making the transmission kit 24 easier and more stable during the rising and falling process.
[0022] Working principle: when it is necessary to level the wall cloth, the operator moves to the designated position through the four universal wheels at the bottom, starts the second motor 27 in the lifting device 2 through the control box 11, and the output end of the second motor 27 drives the screw rod 26 to rotate, and the rotating screw rod 26 drives the transmission kit 24 with the outer surface threaded sleeve to slide up and down on the outer surface of the slide groove 22, and the moving transmission kit 24 performs vertical and stable thread movement under the guidance of the two guide rods 23, and the moving transmission kit 24 drives the extension mechanism 3 to move up and down, thereby realizing the up and down leveling operation of walls of different heights;
[0023] When the width of the scraping needs to be extended, the first motor 42 in the frame 37 is started, and the output end of the first motor 42 drives the gear 41 in the middle of the top of the support plate 36 to rotate, and the rotating gear 41 drives the racks 40 at one end of the two connecting plates 39 to move horizontally in relative directions, thereby driving the extension plate 31 and the scraper 32 to move crosswise, causing the two slide rails 38 at the bottom of the extension plate 31 and the scraper 32 to slide on the outer surfaces of the two sliders 30 respectively, and the extension plate 31 is guided by the two sliding pins 35 on the outer surfaces of the two guide grooves 34 during the movement. When the extension plate 31 moves to the inclined end of the guide groove 34, the outer surface of the extension plate 31 is driven to move along the inclined surface of one end of the scraper 32 while changing its height, so that the extension plate 31 remains parallel to the scraper 32 when it is unfolded and moved to a certain extent. When the gear 41 moves in the opposite direction, the extension plate 31 is driven to descend through the inclined end of the sliding pin 35 while moving to the bottom end of the scraper 32, so as to realize the merger of the scraper 32 and the extension plate 31, thereby realizing the extension and reduction of the scraping width.
[0024] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
