[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figure 1 and Figure 2 As shown, an automatic painting device for exterior wall real stone comprises a mobile trolley 1, a paint bucket 2 is fixedly installed on the rear part of the upper end of the mobile trolley 1, a paint spraying assembly 6 is fixedly installed on the front part of the upper end of the mobile trolley 1, a delivery pump 3 is fixedly installed on the middle part of the upper end of the mobile trolley 1, a delivery pipe 4 is fixedly installed on the upper and lower parts of the rear side of the paint spraying assembly 6, an input end of the delivery pump 3 is fixedly connected to and communicated with the outer surface of the paint bucket 2, an output end of the delivery pump 3 is fixedly connected to and communicated with the outer surface of the delivery pipe 4 on the side away from the paint spraying assembly 6, a ball valve 5 is fixedly installed on the outer surface of the left delivery pipe 4, a pull rod assembly 7 is fixedly connected to the front part of the valve handle of the ball valve 5, a support rod 8 is fixedly connected to the middle part of the lower side of the outer surface of the ball valve 5, and the lower end of the support rod 8 is fixedly connected to the front part of the upper end of the mobile trolley 1.

[0030] The mobile vehicle 1 mentioned above is composed of a vehicle plate, wheels and a handlebar;

[0031] The paint bucket 2 is composed of a bucket body and a bucket cover;

[0032] The ball valve 5 is composed of a valve stem, a valve body, and a ball and a seal inside the valve body;

[0033] The delivery pipe 4 is a hose;

[0034] During the specific implementation process, first, the handlebar of the mobile trolley 1 is held by hand to push the mobile trolley 1 so that the paint spraying assembly 6 is facing the exterior wall to be sprayed; then the lid of the paint bucket 2 is opened, the paint to be sprayed is put into the paint bucket 2, and then the lid is closed; the delivery pump 3 is turned on to extract the paint in the paint bucket 2, and the paint is delivered to the paint spraying assembly 6 connected to the delivery pipe 4 through the delivery pipe 4, so as to spray the exterior wall.

[0035] like Figure 3As shown, the paint spraying assembly 6 includes an electric pole 61 and two paint boxes 64, the bottom end of the electric pole 61 is fixedly connected to the front of the upper end of the vehicle plate of the mobile trolley 1, the upper end of the piston rod at the output end of the electric pole 61 is fixedly connected to a connecting rod 62, and the middle part of the rear end of the upper paint box 64 is fixedly connected to the connecting rod 62, and a plurality of nozzles 63 connected to the paint boxes 64 are fixedly installed at the front ends of the two paint boxes 64, and telescopic assemblies 65 are fixedly connected to the left and right sides of the rear ends of the two paint boxes 64, and an L-shaped rod 66 is fixedly connected to the lower rear ends of the two telescopic assemblies 65, and a buckle assembly 68 is fixedly connected to the left side of the rear end of the L-shaped rod 66, and blocking rods 67 are symmetrically fixedly installed on the left and right sides of the front of the upper end of the vehicle plate of the mobile trolley 1.

[0036] like Figure 4 As shown, the telescopic assembly 65 includes two support columns 651 and an air vent 652. A sliding groove is opened inside the upper support column 651. A round rod 653 is slidably connected to the sliding groove inside the upper support column 651. A telescopic spring 654 is fixedly connected to the opposite surfaces of the two support columns 651. The round rod 653 is fixedly connected to the upper end of the lower support column 651, and the telescopic spring 654 is sleeved on the outer surface of the round rod 653.

[0037] During the specific implementation process, the paint spraying device is moved to the exterior wall that needs to be sprayed and the paint spraying begins, then the electric pole 61 is turned on. Since the rear end of the paint box 64 is fixedly connected to two telescopic components 65, the round rod 653 is slidably connected to the slide groove inside the upper support column 651, and the two ends of the connecting rod 62 are respectively fixedly connected to the electric pole 61 and the paint box 64 located on the upper part. Therefore, during the lifting and lowering process of the electric pole 61, the paint box 64 can also be driven to move up and down. The vent hole 652 opened on the upper support column 651 can enable the round rod 653 to ensure the internal and external balance of the air pressure in the slide groove inside the upper support column 651 during the lifting and lowering process, thereby ensuring the normal operation of the telescopic component 65.

[0038] like Figure 5 As shown, the pull rod assembly 7 includes a pull rod 73 and a handle 74. The upper right end of the pull rod 73 is fixedly connected to the handle 74, and the lower part of the pull rod 73 is rotatably connected to the valve handle of the ball valve 5. A limit block 71 is fixedly installed at the front right end of the valve handle of the ball valve 5. The front end of the limit block 71 is tightly attached to the lower part of the pull rod 73. A spring 72 is fixedly connected to the middle right end of the pull rod 73, and the lower part of the spring 72 is fixedly connected to the middle right end of the valve handle of the ball valve 5.

[0039] like Figure 6 As shown, the buckle assembly 68 includes a rectangular rod 681, an arc piece 1 682 and an arc piece 2 683. The rear portion of the upper end of the rectangular rod 681 is fixedly connected to the arc piece 1 682. The left side of the arc piece 1 682 is rotatably connected to the arc piece 2 683. The outer surfaces of the arc piece 1 682 and the arc piece 2 683 are fixedly connected with a spring piece 684.

[0040] The paint spraying assembly 6 also drives the buckle assembly 68 to rise during the rising process. After rising to a certain height, since the arc piece 2 683 is smaller than the length of the arc piece 1 682, the rod handle 74 can enter the arc piece 1 682, and since the arc piece 2 683 is larger than half the length of the arc piece 1 682, the arc piece 2 683 can wrap the outer surface of the rod handle 74. After the arc piece 1 682 and the arc piece 2 683 wrap the rod handle 74, the buckle assembly 68 continues to rise. Through the power of the rising electric pole 61, the buckle assembly 68 drives the valve stem of the ball valve 5 to rotate 90° counterclockwise through the pull rod assembly 7, thereby closing the ball valve 5, preventing the paint from entering the paint box 64 through the delivery pipe 4 connected to the paint box 64 at the bottom, thereby stopping the spray head 63 at the bottom from spraying paint.

[0041] At the same time, since the vertical projection of the handle (74) is located behind the vertical projection of the axis of the ball valve (5), after the ball valve 5 is closed, the angle between the pull rod 73 of the pull rod assembly 7 and the valve handle of the ball valve 5 is greater than 180°. Therefore, when the buckle assembly 68 moves downward, the arc piece 1 682 and the arc piece 2 683 wrap the handle 74. Similarly, the downward power of the electric pole 61 can be used to drive the ball valve 5 to rotate 90° clockwise, so that the ball valve 5 is opened. After the ball valve 5 is opened, the buckle assembly 68 continues to move downward. Since the arc piece 2 683 and the arc piece 1 682 are rotationally connected, and under the action of the spring piece 684, the handle 74 will be separated from the wrapping of the arc piece 1 682 and the arc piece 2 683, and will not affect the overall upward and downward movement of the paint spraying assembly 6.

[0042] like Figure 7 As shown, the paint box 64 at the lower part includes a blocking plate 641, and both left and right ends of the paint box 64 at the lower part are fixedly connected to the blocking plate 641. The blocking plate 641 and the upper end of the paint box 64 are at the same horizontal plane.

[0043] As the paint spraying assembly 6 continues to rise, the paint box 64 at the upper part continues to rise, and the paint box 64 at the lower part is blocked by the blocking rod 67 when it rises to the initial rising position of the upper paint box 64 due to the blocking plates 641 at the left and right ends, and will not continue to rise.

[0044] It should be noted that the specific installation method of the delivery pump 3 and the electric pole 61, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0045] The working principle of the utility model is:

[0046] First, push the mobile trolley 1 so that the nozzle 63 of the paint spraying assembly 6 faces the wall to be sprayed, open the lid of the paint bucket 2, put the paint in the paint bucket 2, and then close the lid. At this time, the ball valve 5 is in the open state, and the delivery pump 3 is turned on. The delivery pump 3 will extract the paint in the paint bucket 2 and send it to the delivery pipe 4, and then transport it to the paint spraying assembly 6 through the delivery pipe 4, and then spray it out through the multiple nozzles 63 located at the upper and lower parts of the paint spraying assembly 6, thereby completing the spraying of the exterior wall.

[0047] After the spraying starts, the plurality of nozzles 63 at the lower part will start spraying from the base of the wall to be sprayed, and at this time, the electric pole 61 is turned on, and the two paint boxes 64 are driven to rise while the electric pole 61 rises.

[0048] After the two paint boxes 64 continue to rise to a certain height, the arc piece 1 682 and the arc piece 2 683 in the snap assembly 68 will wrap the pole handle 74, and use the force of the continuous rise of the electric pole 61 to drive the valve stem of the ball valve 5 to rotate 90° counterclockwise through the pull rod assembly 7, thereby closing the ball valve 5 and preventing the paint from passing through the delivery pipe 4 connected to the paint box 64 at the bottom and entering the paint box 64 at the bottom, thereby stopping the spray head 63 at the bottom from spraying paint.

[0049] At this time, the paint box 64 at the upper part continues to rise, and when the paint box 64 at the lower part moves to the initial paint spraying position of the paint box 64 at the upper part, the paint box 64 at the lower part is blocked by the blocking rod 67 under the action of the blocking plates 641 set at both ends and stops rising.

[0050] When the paint box 64 at the upper part finishes spraying the uppermost part of the wall, the electric pole 61 descends to drive the paint box 64 downward. Using the force of the descending electric pole 61, the buckle assembly 68 drives the valve stem of the ball valve 5 to rotate 90° clockwise, thereby opening the ball valve 5.

[0051] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
