Technical Field

[0001] The invention relates to the field of building construction, and in particular to a material feeding and wall plastering structure and a full-automatic wall plastering machine. Background Art

[0002] After the main construction of the building is completed, the wall is plastered with lime or other paints, or during decoration, the wall is powdered with paint. The traditional manual operation method is that the personnel use a trowel to apply the paint to the wall, and then use the trowel to smooth the paint. The wall smoothing effect is mainly affected by the proficiency of the operators, and the efficiency is low. The common wall plastering machine now is a wall plastering machine provided with a vertical track. The upper end of the vertical track resists the top of the wall, and the lower end is installed on a horizontal track. The wall plastering is achieved by moving the wall plastering machine up and down on the vertical track and moving the vertical track left and right. Some plastering machines also require manual loading, such as an automatic vertical wall plastering machine disclosed in Chinese patent CN203755618U. The installation and alignment process of this type of wall plastering machine is complicated, and the firmness of the plastering is not good. Summary of the invention

[0003] In order to solve the problem of low efficiency of plastering of building walls, the present invention provides a feeding wall plastering structure and a full-automatic wall plastering machine, which have simple structure, are easy to operate and have good wall plastering effect.

[0004] In order to achieve the above object, the technical solution of the present invention is:

[0005] A material supply and wall plastering structure comprises a supporting platform, a driving motor, a supporting gear, a trowel plate and a spray pipe, wherein the driving motor is arranged on the supporting platform, the driving motor is transmission-connected to the supporting gear, the supporting gear is rotationally connected to the supporting platform, a trowel plate and a spray pipe are respectively arranged on both sides of the supporting gear, and the spray pipe is rotationally connected to the supporting gear.

[0006] Furthermore, a first bearing is eccentrically arranged on the supporting gear, and the outer side of the first bearing is fixedly connected to the supporting gear, and the inner side of the first bearing is fixedly connected to the spray pipe.

[0007] Furthermore, a connecting rod is arranged on one side of the supporting gear, the connecting rod is arranged opposite to the first bearing, and a trowel plate is arranged on the end of the connecting rod.

[0008] Furthermore, the connecting rod includes at least one support rod, and the multiple support rods are detachably connected; or the connecting rod is a pneumatic cylinder, an oil cylinder or an electric telescopic rod.

[0009] Furthermore, the trowel plate includes a plane portion and an inclined portion, the plane portion and the inclined portion are an integral structure, the length ratio of the plane portion to the inclined portion is 4:1, the inclined portion faces the rotation direction of the supporting gear, and the inclined portion is tilted relative to the plane portion to form an inclined section.

[0010] Furthermore, the driving motor and the supporting gear are transmission connected via a gear structure.

[0011] Furthermore, the other end surface of the supporting gear is rotatably connected to the supporting platform via a second bearing, and the second bearing is located outside the first bearing.

[0012] A fully automatic wall plastering machine includes a material feeding and wall plastering structure, a driving support device, a sprayer, a vertical leveling ruler and a laser lamp. The supporting platform is arranged at the upper end of the driving support device, the sprayer is connected to a spraying pipe and sprays the material through the spraying pipe, the vertical leveling ruler is fixedly arranged on the driving support device, and the laser lamp is fixedly arranged at the lower part of the driving support device for leveling in the horizontal direction.

[0013] Furthermore, the driving support device is a robotic arm.

[0014] Through the above technical solution, the beneficial effects of the present invention are:

[0015] 1. In the material feeding and plastering structure of the present invention, a plastering plate and a spraying pipe are respectively arranged on both sides of the supporting gear. The supporting gear is driven to rotate by a driving motor, thereby driving the spraying pipe and the plastering plate to make a circular rotational motion, so that the material feeding by the spraying pipe and the plastering by the plastering plate can be carried out simultaneously, and the material is smoothed in time. With the rotation of the supporting gear, the material at the same position can be squeezed and smoothed by the plastering plate for multiple times, so the wall plastering effect is good, and the efficiency of feeding and smoothing the wall is high.

[0016] 2. The spray pipe of the present invention is rotatably connected to the supporting gear through the first bearing. The first bearing is eccentrically arranged. The spray pipe makes circular motion with the rotation of the supporting gear without self-rotation, thereby preventing the spray pipe from twisting, thus avoiding affecting the stability of the connected material source and affecting the continuous feeding. The material can be continuously fed stably and effectively, and the material can be automatically fed, making the use of the present invention more convenient and efficient.

[0017] 3. The fully automatic wall plastering machine of the present invention has a simple structure and a high degree of automation. It can safely and effectively supply materials continuously, realize material spraying on the wall, and achieve simultaneous spraying and wall smoothing, thereby reducing operation steps, saving operation time, being more efficient, and having good stability and good wall plastering effect.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0024] like Figure 1 to Figure 3 As shown, the present embodiment provides a material supply and plastering structure, comprising a support platform 5 and a driving motor 1, a supporting gear 2, a trowel plate 3 and a spray pipe 4. The support platform 5 in the present embodiment is an "L"-shaped structure, which is used as a support for the present structure. The driving motor 1 is arranged on the horizontal section of the support platform 5, and the driving motor 1 is transmission-connected to the supporting gear 2. The supporting gear 2 is arranged on the vertical section of the support platform 5. The supporting gear 2 is rotatably connected to the support platform 5. A first bearing 6 is arranged on the support gear 2, and the first bearing 6 is rotatably connected to the spray pipe 4. The spray pipe 4 is used to connect to the material source and adapt the spraying path of the material to the rotation of the supporting gear 2, so as to achieve the purpose of spraying material onto the wall as the supporting gear 2 rotates. A trowel plate 3 is also arranged on the supporting gear 2, and the trowel plate 3 and the spray pipe 4 are located on both sides of the outer end surface of the supporting gear 2. The trowel plate 3 smoothes the material sprayed from the spray pipe 4. Since the trowel plate 3 also moves with the supporting gear 2, the purpose of smoothing immediately after spraying the material can be achieved. The feeding and plastering structure of the present invention drives the supporting gear 2 to rotate by the driving motor 1, thereby driving the spraying pipe 4 and the trowel plate 3 to rotate, so as to realize the simultaneous spraying of materials and plastering, thereby achieving the purpose of efficient plastering of the wall surface. At the same time, the spraying pipe 4 is rotatably connected to the first bearing 6, and the spraying pipe 4 is rotatably connected to the supporting gear 2. When the spraying pipe 4 sprays material as the supporting gear 2 rotates greatly, the spraying pipe 4 will not rotate, and the spraying pipe 4 will not be twisted to affect the feeding.

[0025] Specifically, the outer side of the first bearing 6 is fixedly connected to the support gear 2, and the inner side is fixedly connected to the injection pipe 4. The first bearing 6 is eccentrically arranged on the support gear 2. Specifically, the support gear 2 is eccentrically provided with a through hole, and the first bearing 6 is fixedly arranged in the through hole. Through the arrangement of the first bearing 6, when the end of the injection pipe 4 is away from the center of the support gear 2 and rotates with the rotation of the support gear 2, the injection pipe 4 does not rotate on its own.

[0026] Furthermore, a connecting plate is provided on one side of the outer end surface of the support gear 2, and a connecting rod 13 is provided on the connecting plate. The connecting rod 13 is arranged opposite to the first bearing 6, and a trowel plate 3 is arranged at the end of the connecting rod 13. Specifically, the connecting rod 13 is arranged on the side of the support gear 2 facing the wall, that is, the side away from the vertical section of the support platform 5. By setting the connecting rod 13, a distance is left between the main part of the structure and the wall, which improves the convenience of use of the structure, facilitates movement and leveling and positioning, and facilitates construction.

[0027] Specifically, the connecting rod 13 includes at least one support rod, and the multiple support rods are detachably connected. Specifically, the connecting rod 13 can be fixedly connected by sleeve fitting and screw fixing to achieve overall lengthening of the connecting rod 13 and improve the adaptability of the structure in different operating environments. Alternatively, the connecting rod 13 is a cylinder, an oil cylinder or an electric telescopic rod, and the end position of the trowel plate 3 is adjusted in an automated manner.

[0028] Furthermore, the trowel plate 3 includes a plane portion 301 and an inclined portion 302, the plane portion 301 and the inclined portion 302 are an integral structure, the length of the plane portion 301 and the length of the inclined portion 302 are 4:1, the inclined portion 302 faces the rotation direction of the supporting gear 2, and the inclined portion 302 is tilted relative to the plane portion 301 to form an inclined section. Figure 1 As shown, the rotation direction of the support gear 2 is counterclockwise, and the inclined portion 302 faces the lower right. When smoothing the material, the inclined portion 302 simulates the manual smoothing method, and the material is smoothed in the direction of the smoothing movement. The raised inclined portion 302 and the wall can accommodate excess material, and the material squeezed out by the plane portion 301 is guided to the inner side of the rotational movement to ensure the smoothing effect of the plane portion 301. The plane portion 301 is parallel to the wall surface, and the material is squeezed and smoothed. By changing the position of this structure, the material smoothed by the inclined portion 302 can also be further smoothed, and as the position of this structure changes, the same position on the wall surface can be squeezed and smoothed by the trowel plate 3 for multiple times, and the smoothing effect is better. This structure uses the trowel plate 3 and the spray pipe 4 to spray and plaster at the same time, so as to achieve the purpose of efficient wall plastering.

[0029] Furthermore, the driving motor 1 is connected to the supporting gear 2 via a gear structure. Specifically, the output end of the driving motor 1 is fixedly connected to a driving gear, and the driving gear is meshed and rotated with the supporting gear 2.

[0030] Furthermore, the other end surface of the supporting gear 2 is rotatably connected to the supporting platform 5 via a second bearing, and the second bearing is located outside the first bearing 6 .

[0031] like Figure 4As shown, this embodiment also provides a fully automatic wall plastering machine, including the above-mentioned material feeding and plastering structure, and also includes a driving support device 7, a sprayer, a vertical leveling ruler 11 and a laser lamp 12. The supporting platform 5 is arranged on the upper end of the driving support device 7, the sprayer is connected to a material source (not shown in the figure), the sprayer is connected to an air pipe 15 and a material pipe 14, the material is pumped out through the sprayer, the material pipe 14 and the air pipe 15 are connected through a spray gun nozzle, the discharge end of the spray gun nozzle is connected to a spray pipe 4, the sprayer sprays the material through the spray pipe 4, the vertical leveling ruler 11 is fixedly arranged on the driving support device 7 for leveling in the vertical direction, the laser lamp 12 is fixedly arranged at the lower part of the driving support device 7, in this embodiment, there are two laser lamps 12, which emit infrared rays to both sides for leveling in the horizontal direction.

[0032] Furthermore, the driving support device 7 is a robotic arm having six degrees of freedom.

[0033] Before using the device, the robot arm is moved to the front of the target wall, and the verticality of the plane part 301 of the trowel plate 3 is determined by the vertical leveling ruler 11, and the parallelism of the plane part 301 of the trowel plate 3 with the front is determined by the laser light 12, so that the plane part 301 is 20 to 25 mm away from the wall. When in use, the driving motor 1 is operated to drive the support gear 2 to rotate, drive the spraying pipe 4 and the trowel plate 3 to rotate, and the pumping device and the high-pressure air source continue to pump materials, so that the material is sprayed out from the spraying pipe 5. With the rotation of the support gear 2, the spraying and leveling are realized at the same time. When the spraying pipe 4 makes a circular motion with the rotation of the support gear 2, the spraying pipe 4 is connected with the support gear 2 in rotation, and the material in the spraying pipe 4 has gravity, and the spraying pipe 4 will not rotate, thereby avoiding the entanglement of the air pipe 15 and the material pipe 14, and can stably and effectively supply materials. With the movement of the robot arm to the support platform 5, large-area paint plastering of the wall is realized, and efficient automatic wall powdering is realized.

[0034] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structures, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
