Description

Technical Field

[0001] This utility model relates to the field of water sprinkler truck spraying technology, specifically a spraying device for water sprinkler trucks. Background Technology

[0002] Currently, water trucks are mainly used for spraying and irrigating landscaping, irrigating plants in highway medians, cleaning roads, and spraying water for roadside landscaping.

[0003] Most existing sprinkler truck spraying devices use a water tank installed under the truck chassis as the water source. The water pump is driven by a power take-off and drive shaft to complete the spraying work. However, if the water tank is not cleaned for a long time, the water and dust will mix together to form mud, which will block the water outlet pipe. Moreover, the existing devices fix the water gun to the rear seat, so the angle of the water gun cannot be adjusted or the water gun can be raised or lowered to expand the spraying range.

[0004] Therefore, we propose a spraying device for sprinkler trucks to solve the problems mentioned above. Utility Model Content

Most of the spraying devices use a water tank installed under the vehicle chassis as the water source, and drive the water pump through a power take-off and drive shaft to complete the spraying work. However, if the water tank is not cleaned for a long time, the water and dust will mix together to form mud, which will block the water outlet pipe. Moreover, the existing devices fix the water gun to the rear seat, which makes it impossible to adjust the angle of the water gun or raise and lower the water gun to expand the spraying range.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a sprinkler truck body and a water inlet and a chamber 1 formed on the sprinkler truck body.

A water turbine 23 and a striking rod 24 are fixedly installed on the axial side wall of the first rotating shaft 22. A filter screen 25 is fixedly installed on the chamber 13. Two fixing plates 26 are fixedly installed on the side wall of the filter screen 25. A second rotating shaft 27 is rotatably installed between the two fixing plates 26. An arc-shaped rod 28 is fixedly installed on the axial side wall of the second rotating shaft 27. A torsion spring 29 is provided between the arc-shaped rod 28 and the fixing plate 26. A displacement assembly 3 is provided at the upper end of the sprinkler truck body 1.

[0026] The displacement component 3 includes a waterproof box 31 fixedly installed on the sprinkler truck body 1. The waterproof box 31 has a second chamber 32. A motor 33 is fixedly installed on the second chamber 32. A reciprocating threaded rod 34 is fixedly installed at the output end of the motor 33. A limit plate 35 is fixedly installed at the upper end of the sprinkler truck body 1. A limit disc 36 is fixedly installed on the axial side wall of the reciprocating threaded rod 34. A slide rail 37 is fixedly installed at the upper end of the sprinkler truck body 1. A lifting component 4 is provided on the axial side wall of the reciprocating threaded rod 34.

[0027] The lifting assembly 4 includes a displacement block 41 threadedly connected to the axial side wall of the reciprocating threaded rod 34. The displacement block 41 is slidably connected to the slide rail 37. A telescopic cylinder 42 is fixedly installed at the upper end of the displacement block 41. A support plate 43 is fixedly installed at the upper end of the telescopic cylinder 42. A quick-release assembly 5 is provided on the support plate 43.

[0028] The quick-release assembly 5 includes a mounting hole 52 on the side wall of the support plate 43, a mounting block 51 is provided at the upper end of the support plate 43, the mounting block 51 and the support plate 43 are connected by screws 53, a nut 54 is threaded on the axial side wall of the screws 53, a mounting groove 55 is provided on the mounting block 51, and a corner assembly 6 is provided on the mounting groove 55.

[0029] The corner assembly 6 includes a rotating shaft 61, a semi-circular block 62 and a disc 63 fixedly mounted on the axial side wall of the rotating shaft 61, a limit hole 64 on both the disc 63 and the mounting block 51, and a pin 65 inserted through the limit hole 64. A water pump 66 is provided on the chamber 13, and a telescopic pipe 67 is fixedly installed at the outlet of the water pump 66. A water gun 68 is fixedly installed at one end of the telescopic pipe 67. The water gun 68 and the semi-circular block 62 are fixedly connected. A spraying assembly 7 is provided at the lower end of the sprinkler truck body 1.

[0030] The striking rod 24 and the arc rod 28 are on the same horizontal plane. When the striking rod 24 rotates, it can squeeze the arc rod 28.

[0031] The water turbine 23 is located at the lower end of the water inlet 11, and the water flow will drive the water turbine 23 to rotate.

[0032] In this embodiment: the filter screen 25 isolates dust, and water enters the chamber 13 through the water inlet 11. The water flow compresses the water turbine 23, causing it to rotate, which in turn drives the first rotating shaft 22 and the striking rod 24 to rotate. Then, the striking rod 24 compresses the arc-shaped rod 28, causing the other end of the arc-shaped rod 28 to move away from the filter screen 25. After the force is released, the arc-shaped rod 28 strikes the filter screen 25 through the action of the torsion spring 29, shaking off the dust adsorbed on the filter screen 25 and preventing the filter screen 25 from becoming clogged. Subsequently, the motor 33 is started, causing the output end of the motor 33 to drive the reciprocating threaded rod 34 to... The displacement block 41 is slidably connected to the slide rail 37, which restricts the rotational displacement of the displacement block 41. This causes the displacement block 41 to reciprocate on the slide rail 37. At this time, the telescopic cylinder 42 is activated, causing the telescopic end of the telescopic cylinder 42 to move the support plate 43, the mounting block 51, and the water gun 68 up and down. Water can be sprayed on different areas of the ground. When the pin 65 is pulled out, the angle of the water gun 68 can be adjusted to make the spraying more comprehensive. When it is necessary to spray other areas, the nut 54 can be unscrewed and the screw 53 can be pulled out. At this time, the water gun 68 can be picked up and sprayed on the area that needs to be sprayed.

Figure 2 and Figure 6 The spraying assembly 7 includes a water outlet pipe 71 and a drainage pipe 73 fixedly installed at the lower end of the sprinkler truck body 1. The chamber 13 is connected to the water outlet pipe 71. A valve 72 is fixedly installed on the axial side wall of the water outlet pipe 71. Several drainage holes 74 are opened on the drainage pipe 73.

[0034] In this embodiment: opening valve 72 allows water from chamber 13 to be sprayed out through outlet pipe 71, drainage pipe 73, and several drainage holes 74, which can powerfully clean the mud adsorbed on the asphalt road.
