Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a plastering and painting device. Background Art

[0002] As the older generation of construction technicians gradually retire, the new generation of young people are unwilling to participate in the heavy physical labor of plastering and painting. There is already a serious shortage of physical technical construction personnel. Coupled with the high cost of manual construction and uneven construction quality, the construction site is in urgent need of a truly practical plastering and painting mechanical equipment.

[0003] At present, the existing technology is completely unable to improve construction efficiency, ensure construction quality, and meet the actual needs of construction sites of various sizes and layouts. Therefore, it is necessary to further improve and create plastering construction technology and equipment. Utility Model Content

[0004] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and provide a plastering and painting device.

[0005] To this end, the utility model provides a plastering and painting device, including a mobile base, to which an articulated arm base is fixedly connected, on which an articulated arm is arranged, and on the end of which a plastering brush head is arranged. The plastering brush head is square, and a rotating block rotating around the center is arranged inside the plastering brush head, on which a plastering head is fixedly connected, and the shape of the plastering head is a Leroy triangle, and the plastering head can move along the outer frame of the square inside the plastering brush head.

[0006] Furthermore, the articulated arm includes a first joint rotatably engaged on the articulated arm base, a second joint hinged on the first joint, a third joint hinged on the second joint, a fourth joint rotatably engaged on the third joint, a fifth joint hinged on the fourth joint, and a sixth joint rotatably engaged on the fifth joint.

[0007] Furthermore, a feeder and a hopper are also provided on the articulated arm base, and the feeder and the hopper are connected to the plastering brush head through a feed pipe.

[0008] Furthermore, fixed brackets are provided on the second joint and the fourth joint to constrain the follow-up movement of the feed pipe and the joint arm.

[0009] Furthermore, three through holes are arranged in a circumferential array on the wiper head, so that the wiper head forms two Reuleaux triangles of different sizes.

[0010] Furthermore, a feed port is provided on the plastering brush head, and a filter screen is provided between the plastering head and the plastering brush head.

[0011] Furthermore, a flow valve is provided on the plastering brush head to adjust the supply flow of the paint.

[0012] The utility model provides a plastering and painting device, which has the following beneficial effects:

[0013] The utility model uses the free cooperation of five joint arms to keep the plastering brush head vertical and move up and down, left and right, or left and right and up and down on the wall to be constructed, with high flexibility. By setting the shape of the plastering brush head as a Leroy triangle, the paint can be completely covered in the entire plastering brush head, ensuring that there is no dead angle when painting the corners of the wall.

[0014] By opening a through hole, the power demand for the feeder can be effectively reduced, reducing waste of resources; and part of the paint can flow out of the through hole, making the paint more dispersed in the plastering brush head, which can further improve the uniformity of the paint on the wall.

[0020] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present invention. The methods used in the present invention are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercial products unless otherwise specified.

[0021] like Figure 1As shown, the utility model provides a plastering and painting device, including a mobile base 1, a joint arm base 3 is fixedly connected to the mobile base 1, a first joint 14 is rotatably matched on the joint arm base 3, a second joint 15 is hinged on the first joint 14, a third joint 16 is hinged on the second joint 15, a fourth joint 17 is rotatably matched on the third joint 16, a fifth joint 18 is hinged on the fourth joint 17, a sixth joint 19 is rotatably matched on the fifth joint 18, and a plastering brush head 5 is fixedly connected to the end of the sixth joint 19. When in use, the plastering brush head 5 is kept vertically moved up and down, left and right, or left and right, up and down on the wall to be constructed through the free cooperation of the five joint arms.

[0022] The base 3 of the articulated arm is also provided with a feeder 6 and a hopper 7, which are connected to the plastering brush head 5 through a feeding pipe 8. A fixing bracket 9 is provided on the second joint 15 and the fourth joint 17 to constrain the follow-up movement of the feeding pipe 8 and the articulated arm. When in use, paint is added to the hopper 7, and the paint is transported to the plastering brush head 5 through the feeder 6 to paint the wall.

[0023] like Figure 2-4 As shown, the plastering brush head 5 is square, and a rotating block 21 rotating around the center is provided in the plastering brush head 5, and a trowel 24 is fixedly connected to the rotating block 21, and the shape of the trowel 24 is a Leroy triangle. When in use, the rotating block 21 drives the trowel 24 to move along the outer frame of the square in the plastering brush head 5, so that the paint is completely covered in the entire plastering brush head 5, ensuring that there is no dead corner when painting the corners of the wall. A feed port 20 is provided on the plastering brush head 5, which is connected to the feed pipe 8, and a filter screen 23 is provided between the trowel 24 and the plastering brush head 5. By providing the filter screen 23, the paint concentrated from the feed port 20 can be dispersed in advance after passing through the filter screen 23, ensuring that the paint is more evenly distributed on the wall when the subsequent trowel 24 is used for painting.

[0024] Three through holes 22 are provided in a circular array on the plaster head 24, so that the plaster head 24 forms two Leroy triangles of different sizes. It should be noted that because the paint is relatively thick, the feeder 6 needs to provide a large amount of power when supplying the plastering brush head 5. By providing the through holes 22, the power demand for the feeder 6 can be effectively reduced, and resource waste can be reduced; and part of the paint can flow out of the through holes 22, so that the paint is more dispersed in the plastering brush head 5, which can further improve the uniformity of the paint on the wall.

[0025] A flow valve 4 is also provided on the plaster brush head 5 for adjusting the supply flow of the paint. A roller 2 is also provided at the bottom of the mobile base 1. A fixed rod 10 is fixedly connected to the mobile base 1. A telescopic rod 12 is sleeved inside the fixed rod 10. A tightening handle 11 is also provided on the fixed rod 10 for fixing the height of the telescopic rod 12. A visual measuring instrument 13 is fixedly connected to the telescopic rod 12 for performing a panoramic scan of the indoor wall.

[0026] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] However, what is described above is only a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
