For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 3As shown, a two-component spraying device with adjustable ratio is fixedly installed on a spraying vehicle. The spraying device includes a mounting plate 1 and a sliding plate 2. The mounting plate 1 is fixedly installed on the spraying vehicle. Two cylinders 3 are installed on the mounting plate 1. A first piston rod 4 and a second piston rod 5 are slidably arranged in the two cylinders 3 respectively. The first piston rod 4 is fixedly connected to the sliding plate 2. An adjusting component is arranged on the second piston rod 5. The adjusting component is used to adjust the ratio of the cylinder 3 spraying paint. The sliding plate 2 is arranged on the adjusting component. The adjusting component includes a threaded rod 6, which is fixedly connected to the second piston rod 5. The sliding plate 2 is slidably arranged on the threaded rod 6. An adjusting nut 7 is threadedly connected to the threaded rod 6. The adjusting nut 7 is located above the sliding plate 2. The adjusting nut 7 can move up and down along the threaded rod 6 for adjustment. A limit block 8 is provided at the lower end of the threaded rod 6. The limit block 8 is located below the sliding plate 2. In the utility model, the sliding plate 2 slides upward through During the process, the first piston rod 4 is driven to move and slide upward, while the sliding plate 2 slides on the threaded rod 6, and the second piston rod 5 does not move. Until the sliding plate 2 contacts the adjusting nut 7 on the threaded rod 6, the sliding plate 2 continues to move upward, driving the first piston rod 4 and the second piston rod 5 to slide upward synchronously, and the paint can be absorbed into the cylinder 3 until the sliding plate 2 moves to the maximum stroke; similarly, when the sliding plate 2 moves downward, it drives the first piston rod 4 to slide downward, the sliding plate 2 slides downward on the threaded rod 6, and the second piston rod 5 does not move until the sliding plate 2 contacts the limit block 8, the sliding plate 2 continues to move downward, driving the first piston rod 4 and the second piston rod 5 to slide down synchronously, and the paint is squeezed out of the cylinder 3 for spraying. Since the first piston rod 4 and the second piston rod 5 have different strokes in the cylinder 3, the amount of paint sucked into the two cylinders 3 is different, and the amount of the two kinds of paint sprayed is also different. The stroke distance of the sliding plate 2 on the threaded rod 6 is adjusted by moving the position of the adjusting nut 7 on the threaded rod 6 to achieve the effect of adjusting the ratio of the two paints.

[0031] Furthermore, a fixing hole is provided on the lower end surface of the limit block 8, a first mounting hole is provided on the side wall of the limit block 8, and a second mounting hole corresponding to the second piston rod 5 is provided on the side wall. When the second piston rod 5 is inserted into the fixing hole, the first mounting hole and the second mounting hole coincide with each other, and after the pin shaft is inserted into the first mounting hole and the second mounting hole, the limit block 8 is fixedly connected to the second piston rod 5; similarly, the first piston rod 4 and the sliding plate 2 are fixedly connected via a pin shaft.

[0032] Furthermore, the adjusting nut 7 includes a main body 17 and an extension 18 which are fixedly connected.

The main body 17 is adjusted along the length direction of the threaded rod 6, and the main body 17 drives the extension 18 to move, but the distance from the lower end surface of the extension 18 to the upper end surface of the limit block 8 is always less than the thickness of the sliding plate 2, and the sliding plate 2 can always slide on the extension 18. The extension 18 can guide the sliding plate 2, prevent the sliding plate 2 from contacting the threaded rod 6, avoid the thread teeth on the surface of the threaded rod 6 from interfering with the sliding plate 2, and avoid damage to components.

[0033] In another embodiment, the adjusting component is an adjusting rod and a limiting sleeve sleeved on the adjusting rod, the adjusting rod is fixedly arranged on the upper end of the second piston rod 5, the axes of the adjusting rod and the second piston rod 5 are colinear, a plurality of convex rings are arranged on the adjusting rod along the length direction, the limiting sleeve is located above the sliding plate 2, the inner wall of the limiting sleeve is provided with a groove matched with the convex ring, one of the convex rings is clamped in the groove of the limiting sleeve, so that the limiting sleeve is fixed, when moving upward, the sliding plate 2 abuts against the limiting sleeve, driving the second piston rod 5 and the adjusting rod to move upward; when moving downward, the sliding plate 2 contacts the limiting block 8, driving the second piston rod 5 and the adjusting rod to move downward; when adjusting the sliding plate 2 on the adjusting rod, different convex rings can be clamped in the groove of the limiting sleeve by adjusting the limiting sleeve, and the limiting sleeve can be made of flexible materials such as rubber to facilitate the matching of the limiting sleeve and the convex ring.

When the sliding plate 2 slides up and down, the guide rod 10 can limit the sliding plate 2 to prevent the first piston rod 4 and the second piston rod 5 from being broken due to uneven force.

[0035] Furthermore, a power part 11 is installed on the fixed plate 9, and the movable end of the power part 11 is fixedly connected to the sliding plate 2. The power part 11 is a hydraulic cylinder, a pneumatic cylinder or an electric push rod. In the present embodiment, the power part 11 is a hydraulic cylinder, and the cylinder body of the hydraulic cylinder is fixedly arranged on the fixed plate 9. The piston rod passes through the fixed plate 9 and is fixedly connected to the sliding plate 2.

[0037] Furthermore, the material barrel 12 and the cylinder 3 are connected by a pipe 13, and the two ends of the pipe 13 are respectively connected to the bottom of the material barrel 12 and the bottom of the cylinder 3. The pipe 13 adopts a quick-connect pipe, which is convenient for disassembly and cleaning.
