Description

Technical Field

[0001] The utility model relates to a water cannon, in particular to a swing type sprayer. Background Art

[0002] A water truck, also known as a spray truck or a water tanker, is a special vehicle that can be used to spray water, suppress dust, spray pesticides, wash guardrails, etc. on the road surface. It also has the functions of transporting water, draining water, and emergency firefighting. At present, the core uses of water trucks mainly include two aspects: (1) Sprinkling water on the road surface can suppress the flying of dust and increase the air humidity; (2) Watering the green belt plants in the city to ensure the water required by the green belt plants and clean the dust on the leaves of the plants.

[0003] Sprinkler trucks mostly use water cannons to water plants in green belts. The existing water cannons of sprinkler trucks need to be manually adjusted in direction and size, which is not only extremely inconvenient to operate, but also causes some waste of water resources. For example, a sprinkler truck requires two staff members, one responsible for driving and the other responsible for controlling the water cannon; or the driver fixes the water cannon and then drives the car. It can be seen that since the conventional water cannon module of the sprinkler truck lacks automatic control based on environmental conditions and can only perform single-point spraying, the nozzle mode needs to be switched for near-point spraying and far-point spraying. The switching of the spraying mode also takes time, and only one side of the road can be sprayed. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] according to Figure 1 , Figure 2 as well as Figure 6 As shown, a swinging sprayer comprises a fixed box 9 with opening structures on both sides, a water tank 10 is arranged in the fixed box 9, and swinging head assemblies 7 facing the open ends of the fixed box 9 are arranged on the water tank 10, the swinging head assemblies 7 are connected to the nozzle 6, so that water flows out from the nozzle 6, and a swinging mechanism is arranged in the fixed box 9 to drive the swinging head assembly 7 to swing up and down, so as to adjust the spraying distance and range, and the diversion mechanism arranged in the fixed box 9 is connected with the water tank 10 through the connecting pipe 4.

[0025] The diversion mechanism includes a diversion box 11 and a flange connection end 14 connected to the diversion box 11. The flange connection end 14 passes through a window 12 opened on the fixed box 9. The flange connection end 14 is used to connect to a water tank on the sprinkler truck through a pipeline for water supply.

[0026] The connecting pipe 4 is connected in series with a solenoid valve 3, and two water storage tanks 10 are arranged opposite to each other in the fixed box 9. The solenoid valve 3 is used to switch on and off the water flow in the connecting pipe 4 to control one-way spraying or two-side spraying.

[0027] The connecting pipe 4 is connected in series with a pressure pump 2 , and the water pressure in the water storage tank 10 can be increased by the pressure pump 2 .

[0028] according to Figure 3As shown, the swing mechanism includes a rectangular frame 5, a fixed rod 13 and a lifting drive mechanism 1 installed in the fixed box 9. The rectangular frame 5 is rotatably connected to the swing head assembly 7 through the fixed rod 13 so that the nozzle 6 swings up and down. The output end of the lifting drive mechanism 1 is connected to the rectangular frame 5 so as to drive the rectangular frame 5 to move up and down. The present design drives the rectangular frame 5 up and down through the lifting drive mechanism 1 so that the nozzle 6 on the swing head assembly 7 swings up and down to adjust the spraying distance and range. The lifting drive mechanism 1 can select a pneumatic rod, a pneumatic push rod or an electric push rod.

[0029] according to Figure 5 The swing head assembly 7 shown in the figure includes a connection seat 705 arranged on the water tank 10, a hollow sphere 703 and a swing tube 701 connected to the hollow sphere 703, the hollow sphere 703 is rotatably arranged in a spherical cavity 706 opened in the connection seat 705, the input cavity 707 opened in the connection seat 705 is connected to the water tank 10, the swing tube 701 extends to the outside through the movable opening 702 opened on the connection seat 705, and the swing tube 701 is in the movable opening 702. The hollow sphere 703 is provided with a water inlet 704 which is connected to the input cavity 707. The swinging tube 701 is connected to the nozzle 6. When the swinging tube 701 swings up and down in the movable opening 702, the water inlet 704 is always connected to the input cavity 707. At this time, water flows into the input cavity 707, the hollow sphere 703 and the swinging tube 701 in sequence and finally sprays out from the nozzle 6. This design enables the swinging tube 701 to swing up and down when water is flowing, thereby adjusting the angle and range of spraying of the nozzle 6.

[0030] The oscillating head assembly 7 is provided in plurality, and the nozzle 6 adopts a straight nozzle, an atomizing nozzle and a pressurized nozzle. Different modes are realized by loading different nozzles 6, and multi-point spraying can be realized.

[0032] according to Figure 2 As shown, a fixing plate 8 for mounting the water tank 10 is disposed in the water tank 10 , and the fixing plate 8 can improve the stability of the fixing box 9 .

[0033] Working principle: water flows into the diversion box 11, the water storage tank 10 and the swing head assembly 7 in sequence through the flange connection end 14, and then is sprayed out from the nozzle 6. At the same time, the lifting drive mechanism 1 can drive the rectangular frame 5 to move up and down, so that the rectangular frame 5 drives the swing tube 701 to swing up and down through the fixed rod 13, thereby realizing the adjustment of the angle of the nozzle 6, and different functions are realized by replacing the nozzle 6 of different modes.
