Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a wall spraying device for building construction. Background Technology

[0002] During home renovation, spraying equipment is used to apply paint to the walls. Applying paint can add color and texture to the house, enhance the overall decoration style, and make the space more beautiful. At the same time, the paint can form a protective film, effectively preventing the walls from being damaged by moisture, mold, dirt and other external factors, thus extending the service life of the walls.

[0003] For example, an existing patent (publication (announcement) number: CN219158319U) discloses a spraying device for building construction, including a base, a spraying component and an adjustment component. By setting the adjustment component, the user can start the motor by controlling the button. The motor then drives the rotating rod to rotate, which in turn drives the gear to rotate. The gear then drives the toothed plate to rise and fall, which in turn drives the moving plate to move up and down on the surface of the limiting plate. This allows spraying of different heights on the wall without manual operation, reducing the labor intensity of workers.

[0004] When the above-mentioned device is in use, the spraying range is relatively limited because the angle of the nozzle is fixed and it is raised and lowered through the gear plate structure. It cannot spray evenly from the bottom to the top of the wall, resulting in large spraying dead corners. This requires secondary construction by the staff, making it inconvenient to use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a wall spraying device for house construction, which solves the problem that the spraying range of the nozzle is relatively limited due to the fixed angle of the nozzle and the lifting and lowering through the gear plate structure, making it impossible to spray evenly from the bottom to the top of the wall, resulting in large spraying dead corners, requiring secondary construction by workers, and making it inconvenient to use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wall spraying device for house construction, including a mobile cart, wherein a paint tank and a paint delivery pump are fixedly installed in sequence along the length of the mobile cart, the input end of the paint delivery pump is connected to the paint tank, the output end of the paint delivery pump is fixedly connected to a delivery pipe, and the end of the delivery pipe away from the paint delivery pump is fixedly connected to a high-pressure nozzle, and further includes a reciprocating lifting component for driving the high-pressure nozzle to reciprocate and lift, and an angle adjusting component for adjusting the spraying angle of the high-pressure nozzle;

[0007] The angle adjustment assembly includes two crossbars. One end of each crossbar is rotatably connected to a sleeve shaft. The middle of the sleeve shaft is fixedly installed with a high-pressure nozzle. The end of each crossbar away from the sleeve shaft is fixedly connected to an arc rail frame. The sleeve shaft is fixedly connected to an angle adjustment rod in parallel via a connecting rod. A guide rod is fixedly installed inside the arc rail frame. The angle adjustment rod can slide in an arc along the arc rail frame and the guide rod. Springs are provided between the angle adjustment rod and the upper and lower sides of the arc rail frame. An upper pressure rod and a lower pressure rod are fixedly installed on the upper and lower sides of the reciprocating lifting assembly, respectively.

[0008] Preferably, the arc centers of the arc rail frame and the guide rod are both located on the axis of the sleeve shaft, the spring is sleeved on the guide rod, and the angle adjusting rod is located between the upper pressure rod and the lower pressure rod.

[0009] Preferably, the reciprocating lifting assembly includes a lifting frame and a mounting frame. The lifting frame is fixedly installed on the side of the mobile trolley away from the paint tank. A drive motor is fixedly installed on the top of the lifting frame. A reciprocating lead screw is fixedly connected to the output end of the drive motor. The reciprocating lead screw is rotatably connected inside the lifting frame. The reciprocating lead screw is drivenly connected to the middle of the mounting frame, and the mounting frame can slide vertically along the inner side of the drive motor. The upper pressure rod and the lower pressure rod are fixedly installed on the upper and lower sides of the lifting frame, respectively. The two crossbars are both fixedly installed parallel to each other on the side of the mounting frame away from the reciprocating lead screw.

[0010] Preferably, a temperature regulating component for adjusting the temperature inside the paint tank is fixedly installed on the paint tank, and a feed hopper is provided at the eccentric position on the top of the paint tank, with a hopper cover installed on the feed hopper.

[0011] Preferably, the temperature control assembly includes a stirring motor fixedly installed at the center of the top of the paint tank, a stirring shaft fixedly connected to the output end of the stirring motor, an electric telescopic rod fixedly connected to the bottom of the stirring shaft, a base fixedly connected to the bottom end of the electric telescopic rod, a plurality of stirring blades evenly fixed to the outer side of the base, a temperature sensor fixedly installed at the bottom of the inner cavity of the paint tank, a heating wire installed inside the base, a semiconductor cooler and a controller fixedly installed on the paint tank, and the temperature sensor, heating wire and semiconductor cooler are all electrically connected to the controller.

[0012] Preferably, the heat dissipation surface of the semiconductor cooler is arranged facing the outside of the paint box, and the cooling surface is arranged facing the inside of the paint box, and a heat insulation layer is provided on the outside of the paint box.

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

[0014] This invention uses a drive motor to drive a reciprocating lead screw, which in turn drives the high-pressure nozzle to move up and down repeatedly. When the high-pressure nozzle rises to the upper pressure rod and continues to rise, the upper pressure rod will press down the angle adjustment rod, causing the angle adjustment rod to slide downward along the arc of the arc rail and guide rod. At the same time, the connecting rod drives the sleeve shaft to rotate, thereby causing the high-pressure nozzle to tilt upward and spray to the top corner of the wall. Similarly, when the high-pressure nozzle descends to the lower pressure rod and continues to descend, the high-pressure nozzle will tilt downward and spray to the bottom corner of the wall, achieving the effect of spraying without dead angles. It can also reduce the overall height of the device to a certain extent, making it easier to move.

[0015] This invention uses a controller to set the optimal temperature for the corresponding coating. When the temperature sensor detects that the coating temperature is too high or too low, the controller controls the heating wire or semiconductor cooler to be energized, thereby heating or cooling the coating to achieve the optimal operating temperature and improving the overall applicability of the device.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 4 This utility model provides a wall spraying device for house construction, including a mobile cart 1. The mobile cart 1 is fixedly installed with a paint tank 2 and a paint delivery pump 3 along its length. The input end of the paint delivery pump 3 is connected to the paint tank 2, and the output end of the paint delivery pump 3 is fixedly connected to a material delivery pipe 4. The end of the material delivery pipe 4 away from the paint delivery pump 3 is fixedly connected to a high-pressure nozzle 5. It also includes a reciprocating lifting component 6 for driving the high-pressure nozzle 5 to reciprocate and lifting, and an angle adjusting component 7 for adjusting the spraying angle of the high-pressure nozzle 5.

[0024] The angle adjustment assembly 7 includes two crossbars 71. One end of the crossbar 71 is rotatably connected to a sleeve shaft 72. The middle part of the sleeve shaft 72 is fixedly installed with the high-pressure nozzle 5. The end of the crossbar 71 away from the sleeve shaft 72 is fixedly connected to an arc rail frame 73. The sleeve shaft 72 is fixedly connected to an angle adjustment rod 75 in parallel through a connecting rod 74. A guide rod 76 is fixedly installed inside the arc rail frame 73. The angle adjustment rod 75 can slide in an arc along the arc rail frame 73 and the guide rod 76. Springs 77 are provided between the angle adjustment rod 75 and the upper and lower sides of the arc rail frame 73. An upper pressure rod 78 and a lower pressure rod 79 are fixedly installed on the upper and lower sides of the reciprocating lifting assembly 6, respectively.

[0025] Preferably, the arc centers of the arc rail frame 73 and the guide rod 76 are both located on the axis of the sleeve shaft 72, the spring 77 is sleeved on the guide rod 76, and the angle adjustment rod 75 is located between the upper pressure rod 78 and the lower pressure rod 79.

[0026] Specifically, the paint in the paint tank 2 is pumped out by the paint delivery pump 3 and sprayed out from the high-pressure nozzle 5 through the delivery pipe 4. This is the existing technology. The high-pressure nozzle 5 can be moved up and down by the reciprocating lifting assembly 6. When the high-pressure nozzle 5 rises to the upper pressure rod 78 and continues to rise, the upper pressure rod 78 will press down the angle adjustment rod 75, causing the angle adjustment rod 75 to slide down the arc along the arc rail frame 73 and the guide rod 76. At the same time, the connecting rod 74 drives the sleeve shaft 72 to rotate, thereby causing the high-pressure nozzle 5 to tilt upward for spraying. Similarly, when the high-pressure nozzle 5 descends to the lower pressure rod 79 and continues to descend, the high-pressure nozzle 5 will tilt downward for spraying.

[0027] Among them, the springs 77 on the upper and lower sides can keep the angle adjustment rod 75 horizontal when it is not subjected to external force, and can restore its horizontal state after being subjected to external force.

[0028] Preferably, the reciprocating lifting assembly 6 includes a lifting frame 61 and a mounting frame 64. The lifting frame 61 is fixedly installed on the side of the mobile trolley 1 away from the paint tank 2. A drive motor 62 is fixedly installed on the top of the lifting frame 61. A reciprocating lead screw 63 is fixedly connected to the output end of the drive motor 62. The reciprocating lead screw 63 is rotatably connected inside the lifting frame 61. The reciprocating lead screw 63 is connected to the middle of the mounting frame 64 through a transmission connection. The mounting frame 64 can slide vertically along the inner side of the drive motor 62. The upper pressure rod 78 and the lower pressure rod 79 are fixedly installed on the upper and lower sides of the lifting frame 61, respectively. The two crossbars 71 are both fixedly installed parallel to each other on the side of the mounting frame 64 away from the reciprocating lead screw 63.

[0029] Specifically, the reciprocating screw 63 is driven to rotate by the drive motor 62, which can drive the mounting bracket 64 to move up and down repeatedly, thereby cooperating with the angle adjustment component 7 to enable the high-pressure nozzle 5 to spray paint without dead angles.

[0030] Preferably, a temperature regulating component 8 that can adjust the temperature inside the paint tank 2 is fixedly installed on the paint tank 2, and a feed hopper 9 is provided at the eccentric part of the top of the paint tank 2, with a hopper cover 10 installed on the feed hopper 9.

[0031] Preferably, the temperature control assembly 8 includes a stirring motor 81 fixedly installed at the center of the top of the paint tank 2. The output end of the stirring motor 81 is fixedly connected to a stirring shaft 82. An electric telescopic rod 83 is fixedly connected to the bottom of the stirring shaft 82. A base 84 is fixedly connected to the bottom end of the electric telescopic rod 83. Multiple stirring blades 85 are evenly fixed on the outer side of the base 84. A temperature sensor 86 is fixedly installed at the bottom of the inner cavity of the paint tank 2. An electric heating wire 87 is installed inside the base 84. A semiconductor cooler 88 and a controller are fixedly installed on the paint tank 2. The temperature sensor 86, the electric heating wire 87, and the semiconductor cooler 88 are all electrically connected to the controller.

[0032] Specifically, under different seasonal room temperature conditions, the paint in paint tank 2 cannot be at its specified optimal operating temperature, which will affect the viscosity, adhesion, and drying time of the paint. In the above situation, the optimal temperature of the paint can be set by the controller. When the temperature sensor 86 detects that the paint temperature is high or low, the controller controls the heating wire 87 or the semiconductor cooler 88 to be energized, thereby heating or cooling the paint. In addition, the stirring motor 81 drives the stirring shaft 82 to rotate, and the electric telescopic rod 83 reciprocates to make the stirring blade 85 stir the paint evenly up and down, thereby accelerating the heating or cooling time of the paint.

[0033] Preferably, the heat dissipation surface of the semiconductor cooler 88 is arranged facing the outside of the paint box 2, and the cooling surface is arranged facing the inside of the paint box 2. A heat insulation layer 89 is provided on the outside of the paint box 2.

[0034] The feed hopper 9 can be sealed by the hopper cover 10 to reduce convection inside and outside the paint box 2, thereby ensuring that the paint box 2 maintains the optimal temperature. The heat insulation layer 89 is used to reduce the temperature transfer between the inside and outside of the paint box 2.

[0035] The working process of this utility model is as follows:

[0036] In use, the reciprocating screw 63 is driven to rotate by the drive motor 62, which drives the high-pressure nozzle 5 to move up and down repeatedly. When the high-pressure nozzle 5 rises to the upper pressure rod 78 and continues to rise, the upper pressure rod 78 will press down the angle adjustment rod 75, causing the angle adjustment rod 75 to slide downward along the arc rail frame 73 and the guide rod 76. At the same time, the connecting rod 74 drives the sleeve shaft 72 to rotate, thereby causing the high-pressure nozzle 5 to tilt upward and spray to the top corner of the wall. Similarly, when the high-pressure nozzle 5 descends to the lower pressure rod 79 and continues to descend, the high-pressure nozzle 5 will tilt downward and spray to the bottom corner of the wall.

[0037] When in use, the controller sets the optimal temperature for the corresponding coating. When the temperature sensor 86 detects that the coating temperature is too high or too low, the controller controls the heating wire 87 or the semiconductor cooler 88 to be energized, thereby heating or cooling the coating to achieve the optimal operating temperature.
