Description

Technical Field

[0001] The present application relates to the field of spraying machines, and in particular to a spraying machine that is convenient for spraying large equipment. Background Art

[0002] A sprayer is a professional coating equipment. Its main working principle is to pressurize the inhaled paint and transport it to the spray gun of the sprayer through a high-pressure hose. The spray gun instantly atomizes the paint and releases it onto the surface of the object to be coated. Currently, most common sprayers have two driving wheels at the rear and a pad at the front. When the sprayer needs to be moved, the front half of the sprayer can be lifted to move. When spraying, it mainly relies on the pipes extending from the sprayer to spray at multiple angles.

[0003] With respect to the above-mentioned related technologies, the inventor believes that common sprayers have the defect of being inconvenient to move when spraying large equipment. The movement of common sprayers mainly relies on the staff to lift the front half to move, but the sprayer itself is heavy. When spraying large equipment, the staff have to lift and put down the sprayer frequently, which greatly affects the work efficiency. Therefore, a sprayer that is convenient for spraying large equipment is proposed to solve the above problem.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a spraying machine that is convenient for spraying large equipment. Figure 1 , a spraying machine convenient for spraying large equipment, including a main machine 1, two driving wheels 2 are arranged at the bottom rear end of the main machine 1, a fixed block 3 is arranged at the bottom front end of the main machine 1, a flat plate 4 is arranged on the side wall of the fixed block 3, support rods 5 are arranged on both sides of the flat plate 4, the side walls of the support rod 5 are rotatably connected with the first rotating rod 6, and the side walls of the flat plate 4 are respectively provided with movement grooves 7, and a slide rod 8 is slidably connected in the movement groove 7, and the side wall of the slide rod 8 is rotatably connected with the second rotating rod 9, and the other end of the second rotating rod 9 is rotatably connected with the side wall of the first rotating rod 6, and a center rod 10 is arranged at the connection between the first rotating rod 6 and the second rotating rod 9, and a moving wheel 11 is arranged on the side wall of the center rod 10. In the normal state, only the two driving wheels 2 and the fixed block 3 are in contact with the ground. Therefore, if you want to move the main machine 1, you only need to lift the front end of the main machine 1. When switching to the mobile state, the moving wheel 11 will replace the fixed block 3 to contact the ground, and the main machine 1 can be moved at will, and the staff can move the main machine 1 more easily and freely;

[0020] Reference Figure 2 The top wall of the flat plate 4 is provided with a pushing mechanism, which includes a top rod 12, a moving rod 13 and two side rods 14. The two side rods 14 are rotatably connected to the side walls of the slide bar 8 respectively. The top rod 12 is arranged on the side walls of the two side rods 14 away from the slide bar 8. A vertical groove 15 is provided on the top wall of the flat plate 4. The moving rod 13 is arranged on the bottom wall of the top rod 12. The moving rod 13 is slidably connected to the inner wall of the vertical groove 15. The movement of the top rod 12 will drive the moving rod 13 and the two side rods 14 to move together, thereby reducing the angle between the first rotating rod 6 and the second rotating rod 9, so that the moving wheel 11 falls.

[0021] Reference Figure 3 A through hole 16 is provided on the bottom wall of the vertical groove 15, and a protrusion 17 is installed in the through hole 16. The protrusion 17 is designed to be arc-shaped at one end near the motion rod 13. A cross bar 18 is installed on the bottom wall of the protrusion 17. The cross bar 18 is located below the plate 4. A spring 19 is installed on the top wall of the cross bar 18. The other end of the spring 19 is fixedly connected to the bottom wall of the plate 4. A pedal 23 is installed at one end of the cross bar 18 away from the protrusion 17. The length and width of the pedal 23 are both greater than the length and width of the cross bar 18. The pedal 23 is mainly provided to facilitate the staff to step on it, so that the protrusion 17 moves downward and releases the restriction on the motion rod 13;

[0022] Two limiting holes 20 are provided on the side wall of the cross bar 18, and two round rods 21 are installed on the bottom wall of the flat plate 4. The two round rods 21 pass through the two limiting holes 20 respectively, and a baffle 22 is installed on the bottom wall of the round rod 21. The baffle 22 is mainly provided to prevent the cross bar 18 from separating from the round rod 21. The provision of the two round rods 21 can also play a role in limiting the movement direction of the cross bar 18.

[0023] The implementation principle of the spraying machine for spraying large equipment in the embodiment of the present application is as follows: when the staff needs to put the main machine 1 into motion state, they can push the top rod 12 forward with their feet, so that the side rod 14 drives the slide bar 8 to slide in the motion groove 7, thereby reducing the angle between the first rotating rod 6 and the second rotating rod 9, so that the height of the motion wheel 11 is reduced until the motion wheel 11 touches the ground, at which time the motion rod 13 will pass through the protrusion 17, and the position of the motion rod 13 will be clamped between the protrusion 17 and the vertical groove 15, so that the position of the motion wheel 11 is fixed, which makes it more convenient for the staff to pull the main machine 1 to move together, so as to spray large equipment easily;

[0024] When you want to change the host 1 into a fixed state, you can step on the pedal 23 downward to stretch the spring 19 and move the protrusion 17 downward, so that the movement rod 13 loses the restriction of the protrusion 17. Under the action of gravity, the movement rod 13 can move forward naturally, so that the movement wheel 11 is retracted, and only the fixed block 3 at the front end of the host 1 is in contact with the ground, which makes it more convenient to fix the host 1.
