Description
Technical field
The present invention relates to a kind of automatic watering machine.
Background technology
In fruits and vegetables plantation, some are had to the plant of particular requirement for soil moisture, often need to keep the moistening of soil at any time, but can not water be watered too much, in order to avoid rotten.Therefore, grower must periodically for the soil of these plants of plantation waters within one day.This is for the plantation of large-area fruits and vegetables, is a very loaded down with trivial details job, bothersome effort.And because everyone exists individual difference, that grasp irrigation amount therefore, it is possible to accurate is the people that minority long campaigns this kind of fruits and vegetables are planted.This is extremely unfavorable for engaging new person to manage fruits and vegetables plantation, is unfavorable for fruits and vegetables planting scale to expand.In addition, existingly be generally for the large area water pipe of irrigating that carries out watering the fixing metallic conduit be fixedly installed between field, this makes pipe arrangement cost increase, and makes the field being arranged pipeline be used as appointed purposes and after pipe arrangement completes, can not be used as other purposes easily again.
Summary of the invention
The invention is intended to provide a kind of automatic watering machine, waste time and energy and the problem that there are differences of everyone irrigation amount to solve manually to water.
Automatic watering machine in this programme, comprises control box and header tank, is provided with the control circuit that waters in described control box, described in the control circuit that waters be connected with probe and water pump, described probe is connected with the Connection Block be arranged on outside control box; Described water pump is connected on header tank; The water side of described water pump is connected with communicating pipe, and described communicating pipe is removably connected with water pipe; Described probe as humidity sensor, described in the control circuit that waters comprise the on-off circuit be connected with humidity sensor, the relay be connected with on-off circuit, described water pump is connected with the normally opened contact of relay.
Operation principle and beneficial effect:
During work, probe is inserted in soil, the humidity sensor formed by probe changes the moisture signal of soil into electrical signal transfer to on-off circuit, make on-off circuit conducting or cut-off, make the relay adhesive be connected with on-off circuit, the water pump motor be connected with relay normally open contact starts to rotate, and makes pump working.Just fetched water in header tank by water pump when soil is drier, and by water from being delivered to communicating pipe water pipe, automatic watering is carried out to soil.
The present invention is by the control circuit that waters, and the moistening degree according to soil carries out automatic watering, decreases manual steps, has effectively saved the operating time.And, because the structure of probe fixedly feel the parameter of its humidity sensor formed time fix, the irrigation amount that the signal come by sensor passes is carried out when watering operation is certain, effectively can avoid the otherness of individuality during manual operation, anyone easily can use automatic watering machine, be conducive to automatic watering machine batch to use, the humidity of all soil can be kept identical moistening degree, be conducive to implant mass fruits and vegetables of the same race.
Further, described on-off circuit comprises the first triode of NPN type, the second triode and the 3rd triode, between the colelctor electrode that described humidity sensor is connected to the first triode and base stage; The emitter stage of described first triode is connected with the base stage of the second triode, and the colelctor electrode of described second triode is connected with the base stage of the 3rd triode, and the emitter stage of described second triode is connected with the emitter stage of the 3rd triode; The colelctor electrode of described 3rd triode is connected with relay.When soil moisture is higher, the interelectrode resistance of the humidity sensor in probe is less, and the first triode and the second triode are in conducting state, the 3rd triode cut-off.When becoming dry gradually when soil water evaporation, because the interelectrode resistance of humidity sensor becomes large, make the first triode and the cut-off of the second triode, 3rd triode ON, engage relay works, thus the water pump connected with relay normally open contact is rotated, to that block soil water supply inserting probe.When the moisture in soil is increased to a certain degree, the interelectrode resistance of humidity sensor two reduces, and when reaching certain value, the first triode and the second triode ON, the 3rd triode cut-off, relay quits work, and water pump stops operating.When soil becomes dry again, repeat aforesaid operations, thus enable the humidity that soil keeps more constant.
