Description

Technical Field

[0001] This utility model relates to the field of exterior wall spraying technology, specifically to a high-efficiency automatic exterior wall coating spraying equipment. Background Technology

[0002] During the construction process, after the wall is built, a layer of paint is usually applied to the outer surface of the wall to ensure its aesthetic or waterproof performance. The application process can be done manually with a roller or by spraying with a spray gun. When using a spray gun, it has the advantage of higher work efficiency.

[0003] A search revealed a patent with application number CN202220113973.6, which discloses an automatic exterior wall coating spraying device for building construction. The device includes a mounting base, a mounting shell, and a handle. The mounting base has a mounting block underneath, and the mounting block has rollers underneath. A brake is provided on one side of the rollers. This automatic exterior wall coating spraying device for building construction allows for convenient spraying of exterior walls. The mounted rollers and handle facilitate easy movement and can be easily moved to a lifting device.

[0004] However, in actual use, the above-mentioned patent has the following defects: the nozzle cannot be protected when idle, which can easily lead to collisions between external objects and the nozzle and cause damage. In addition, external dust and debris can easily enter the nozzle. Therefore, we propose a high-efficiency automatic spraying equipment for exterior wall coatings. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency automatic spraying device for exterior wall coatings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency automatic exterior wall coating spraying device, including a fixed frame, an opening on the left side of the front of the fixed frame, a protective shell in front of the fixed frame, the front side of the protective shell being an open structure, a spray pipe that can move back and forth inside the protective shell, and multiple nozzles fixedly installed on the front side of the spray pipe.

[0007] Furthermore, two symmetrically arranged first electric push rods are fixedly connected to the rear side of the inner wall of the protective sleeve. The telescopic end of the first electric push rod is fixedly connected to the rear side of the spray pipe. A protective baffle is movably connected to the front side of the protective sleeve. The protective baffle is made of transparent acrylic material, which makes it convenient for operators to observe the status of the nozzle.

[0008] Furthermore, a second electric push rod is fixedly connected to the top of the protective casing, and a support plate is fixedly connected to the telescopic end of the second electric push rod. In use, the support plate can be moved up and down by the second electric push rod.

[0009] Furthermore, a fixing rod is fixedly connected to the bottom of the support plate, and the bottom of the fixing rod is fixedly connected to the top of the protective baffle.

[0010] Furthermore, a base is fixedly connected to the bottom of the fixed frame, and casters are fixedly installed at the four corners of the bottom of the base. A paint tank is fixedly connected to the top of the base, and a door is installed on the right side of the paint tank to facilitate cleaning of the inner wall of the paint tank by the user. A feeding pipe is fixedly connected to the top of the paint tank to replenish paint into the paint tank.

[0011] Furthermore, a delivery pump is fixedly connected to the bottom front side of the paint tank, and a material extraction pipe is fixedly connected to the rear side of the delivery pump. The rear end of the material extraction pipe is fixedly connected to the paint tank. A flexible hose is fixedly connected to the front side of the delivery pump. A movable port is opened on the rear side of the protective casing. The end of the flexible hose away from the delivery pump passes through the through port and the movable port in sequence and extends to the outside of the movable port and is fixedly connected to the rear side of the spray pipe. The flexible hose and the movable port are movably connected.

[0012] Furthermore, a trolley handle is fixedly connected to the top rear side of the base, making it easy for the user to push the device to move. A servo motor is fixedly connected to the top of the fixed frame, and a lead screw is fixedly connected to the output end of the servo motor. The bottom end of the lead screw passes through the fixed frame and extends into the interior of the fixed frame. The lead screw and the fixed frame are movably connected. A threaded plate is threadedly connected to the surface of the lead screw. The front side of the threaded plate extends to the outside of the fixed frame and is fixedly connected to the rear side of the protective shell. In use, the servo motor can drive the lead screw to rotate forward and backward, thereby enabling the threaded plate to drive the protective shell to move up and down, which greatly improves the spraying range of the nozzle and thus greatly improves the spraying efficiency. The left and right sides of the threaded plate are movably abutting against the inner wall of the fixed frame, so that the threaded plate cannot rotate with the lead screw. A controller is fixedly installed on the right side of the fixed frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. When the nozzle is not working, the nozzle and spray tube can be retracted into the protective housing. Then, the second electric push rod drives the protective baffle to block the front of the protective housing, thereby completely enclosing the nozzle. This effectively prevents external dust and debris from entering the nozzle and avoids direct collision between the nozzle and external objects, thus preventing damage.

[0015] 2. The protective baffle of this utility model is made of transparent acrylic material, which makes it convenient for operators to observe the status of the nozzle. Attached Figure Description
