Summary of the invention
At the problems referred to above, main purpose of the present utility model be to provide a kind of easy and simple to handle, practicality good, can adjust at any time the sprinkling irrigation operation irrigation controller.
For achieving the above object, a kind of irrigation controller provided by the utility model, it is used for the start and stop of control connection at the water pump of electric power loop primary side, and the start and stop of Irrigation shower head, it is characterized in that: described electric power loop secondary side is connected with a change-over switch, one contact of described change-over switch connects the master control time relay, a described master control time relay coil component control time relay in parallel, one of them normally opened contact of the described branch control time relay connects an A.C. contactor, the normally opened contact of described A.C. contactor and described water pump polyphone, control the start and stop of described water pump, the normally opened contact of all the other each described branch control time relays connects the main coil of a magnetic valve respectively, the normally opened contact of each the described magnetic valve described Irrigation shower head of contacting is respectively controlled the start and stop of described Irrigation shower head; Another contact of described change-over switch is connected in parallel to one group of hand switch, each described hand switch is corresponding one by one with described A.C. contactor and each described branch control time relay, is connected on respectively between described A.C. contactor, the branch control time relay and the described change-over switch.
In the above-mentioned the technical solution of the utility model, the described master control time relay is the ON time sum that connects the branch control time relay of each described Irrigation shower head with the ON time of the branch control time relay that is connected described A.C. contactor.
Described A.C. contactor and each described minute controlled relay also are connected in parallel to indicator lamp respectively.
Adopt technique scheme, the utlity model has the advantage that operation is simple, anyly can operate adjustment per capita, need not special technical staff.And the utility model adopts the time relay and A.C. contactor commonly used on the market can realize that circuit is simple, long service life, and operation and maintenance is with low cost, and the sprinkling irrigation operation that is fit to various scales is used.

Embodiment
In order to describe structure of the present utility model and characteristics in detail, existing following preferred embodiment of act and conjunction with figs. are described as follows.
A kind of irrigation controller provided by the utility model, it is used for the start and stop of control connection at the water pump 1 of electric power loop primary side, and the start and stop of Irrigation shower head.As shown in Figure 1, the primary side of electric power loop is connected in parallel to water pump 1, power supply indicator 1HD, and transformer 1BY, be connected with a change-over switch HK at electric power loop secondary side (secondary side of transformer 1BY just), the contact of change-over switch HK connects master control time relay 1JS, the coil of a master control time relay 1JS component control time relay 2JS～6JS in parallel again, the coil that divides the normally opened contact connection A.C. contactor 1B of control time relay 2JS, the normally opened contact of A.C. contactor 1B is then contacted the start and stop of control of pump 1 with water pump 1.The main coil that other divide the normally opened contact of control time relay 3JS～6JS to connect magnetic valve 2B～5B respectively, the normally opened contact of each the magnetic valve 2B～5B Irrigation shower head (not shown) of then contacting is respectively controlled time of each Irrigation shower head water spray and water spray.
Another contact of change-over switch HK is connected in parallel to one group of hand switch 2HK～6HK, hand switch 2HK is connected between the main coil and change-over switch HK of A.C. contactor 1B, then corresponding one by one each minute control time relay of all the other hand switch 3HK～6HK 3JS～6JS is connected on respectively between the main coil and change-over switch HK of each minute control time relay.A.C. contactor 1B and each minute control time relay 2JS～6JS also is connected in parallel to indicator lamp 2HD～6HD respectively simultaneously.
Adopt foregoing circuit, the utility model can be realized automatic irrigation control and the manually switching of sprinkling irrigation control by change-over switch HK, and can be by adjusting the parameter of the time relay, the time of each shower nozzle sprinkling irrigation operation is set, and normally master control time relay 1JS is set to the ON time sum that other divides control time relay 3JS～6JS with the ON time that divides control time relay 2JS.The utility model also can directly adopt manual working, utilizes each hand switch 2HK～6HK to select the length of operation shower nozzle and activity duration.As shown in Figure 2, the hand switch of each shower nozzle of control is corresponding in twos with indicator lamp on the panel of the present utility model, and the operator comes into plain view, and operates very easy.Each time relay 1JS～6JS also is arranged on the front panel, is convenient to the adjustment time.
In sum, the utlity model has the advantage that operation is simple, anyly can operate adjustment per capita, need not special technical staff, can adjust the sprinkling irrigation operation at any time according to actual needs.And the utility model adopts the time relay and A.C. contactor commonly used on the market can realize that circuit is simple, long service life, and operation and maintenance is with low cost, and the sprinkling irrigation operation that is fit to various scales is used.
The setting of the time relay, magnetic valve and number of switches is not exceeded with the foregoing description in the utility model, can be according to the actual demand setting, to satisfy the needs of independent each shower nozzle of control.
