Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of cutaway view of embodiment;
Fig. 2 is the embodiment of the fertilizer distributor arranging support.
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Shown in composition graphs 1, the present embodiment provides a kind of fertilizer distributor, comprises fertilizer bucket 1, water filling bucket 2, feeding barrel 3 and agitating device 4.The bottom of fertilizer bucket 1 is connected to the entrance of feeding barrel 3 by magnetic valve.Height after fertilizer bucket 1 couples together with feeding barrel 3 is the same with the height of water filling bucket 2.Top centrally line inlet porting 41 and the entrance 42 symmetrically of agitating device 4.The outlet of feeding barrel 3 is connected to entrance 41 by magnetic valve.The outlet of water filling bucket 2 is connected to entrance 42 by magnetic valve.Gravity sensor 5 is fixed in the bottom of feeding barrel 3.Water filling bucket 2 internal fixtion level sensor 6.The inner chamber 43 of agitating device 4 is cylindrical shape.Connecting hole 44 is offered at the center of inner chamber 43.The rotating shaft of rotating vane 45 passes connecting hole 44, and by being connected with the output shaft of motor (not shown).Between rotating vane 45 and connecting hole 44, sealing ring is set.The end of rotating vane 45 connects scraping blade 46, and scraping blade 46 can touch the inwall of agitating device 4.All magnetic valves, gravity sensor 5, level sensor 6 are all connected to controller (not shown), are carried out the work of Controlling solenoid valve, gravity sensor 5 and level sensor 6 by controller.
For adapting to the use of organic fertilizer, in one embodiment, the outlet of agitating device 4 connects the entrance of filter cartridge 8, by the filter screen of filter cartridge 8 inside by the solid matter filtering in organic fertilizer, prevents fertilizer from blocking flexible pipe 6.One end of the outlet connection traffic sensor 7 of filter cartridge 8, in other end connecting hose 6, the outlet of flexible pipe 6 arranges valve.Flow sensor 7 detects the fertilizer flow in flexible pipe 6, different according to the plant of spraying, the opening degree of by-pass valve control, and then the flow that control fertilizer flows out from flexible pipe 6, the flow that flow sensor 7 is detected meets demand, realizes the sprinkling consumption automatically controlling fertilizer.
Conveniently carry out transporting and carrying, in one embodiment, as Fig. 2, also comprise support 9 and spring 10.The bottom of support 9 arranges movable pulley 91, and top arranges screens 92.The side of support 9 connects handrail 93.Filter cartridge 8 is placed in screens 92.The lateral wall of filter cartridge 8 welds eight links 81 equably.Each link 81 is fixedly connected with a spring 10.The other end of spring 10 is fixed on the periphery of screens 92 equably.Agitating device 4 around getting up, and makes agitating device 4 be fixed in screens 92 by eight springs 10, avoids agitating device 4 run-off the straight in transportation.
Operation principle of the present utility model is as follows:
Controller controls water filling bucket and injects water to agitating device, is detected the water yield injected by water level sensor.While water filling, control fertilizer bucket and throw in fertilizer to feeding barrel, gravity sensor at the bottom of feeding barrel detects the weight of the fertilizer thrown in.When reaching the water yield of needs, valve-off, stops water filling.When fertilizer reaches the water yield of needs, valve-off, fertilizer bucket stops throwing in, and opens the valve between feeding barrel and agitating device simultaneously, makes the fertilizer in feeding barrel inject agitating device inner.Agitating device stirs water and fertiliser mixtures, and when rotating vane rotates, scraping blade scratches inwall, prevents fertilizer from sticking at inwall.Fertiliser mixtures after dilution flows into filter cartridge and filters, and the fertilizer after filtration is sprayed by flexible pipe.When spraying, the data that can detect according to flow sensor, control the valve opening degree of hose end, make fountain height meet the needs of use.
