Embodiment 1

[0015] Embodiment 1, the working process of releasing the dragging line

[0016] Set the operating cycle time of the signal timer 9 to be 10min, and the percentage of start-up time is 100%. With the positive pole thick power line 5 of winch 11, there is electric current all the time. Close and release the button 15, release the towing line 16 on the winch 11, and manually make the mobile sprinkling irrigation unit 17 away from the winch 11 to the position where the sprinkling operation starts.

Embodiment 2

[0017] Embodiment 2, the working process of intermittent drag sprinkler irrigation unit

[0018] Set the operating cycle time of the signal timer 9 to 60s, and the percentage of the starting time is 50%, that is to say, the signal output 10 runs according to the regular period of the closing time of 30s and the opening time of 30s, and the signal output 10 controls the closing of the relay 12 Time 30s and opening time 30s discontinuous operation, make the positive pole thick power line 5 that connects vehicle power supply 3 and winch 11 have current in 30s and then cut off current discontinuous operation in another 30s. Closing the drag button 14 realizes the technical effect of the intermittent dragging of the mobile sprinkling irrigation unit 17 starting and running for 30 seconds and then stopping the operation for 30 seconds, so that the mobile sprinkler irrigation unit 17 reaches the optimal working condition.

Abstract

The invention discloses a control system and a control method for an intermittent dragging sprinkler irrigation unit, which belongs to the field of agricultural water-saving irrigation. The system of the invention includes a negative thick power cord, a thin power cord, a vehicle power supply, a positive power clamp, a positive thick power cord, a negative power clamp, a voltage converter, a power switch, a signal timer, a winch, a relay, a fuse, and a tow line. Mobile sprinkler irrigation unit. The winch is connected to the mobile sprinkler irrigation unit through a tow line. The implementation method of the present invention is to close the power switch to connect the winch to the power provided by the vehicle power supply, set the signal timer, connect and disconnect the positive thick power cord connecting the vehicle power supply and the winch, including releasing the towing There are two states of linear and intermittent dragging of the sprinkler irrigation unit. The invention can accurately control the running time of moving to the next working position during the working process of the mobile sprinkler irrigation unit, thereby ensuring that the mobile sprinkler irrigation unit achieves the optimal working condition effect, and can be applied in sprinkler irrigation operations.

Description

technical field [0001] The invention belongs to the field of agricultural water-saving irrigation. The invention relates to a control system related to the operating state of a mobile sprinkler irrigation unit, in particular to a control technology for intermittently towing sprinkler irrigation units. Background technique [0002] The light and small mobile sprinkler irrigation unit is a relatively representative irrigation unit. Its typical matching method is a single power machine, a single water pump, and a single type of sprinkler head. The unit is flexible and flexible to meet the needs of rural development in China. At present, the light and small mobile sprinkler irrigation units have problems such as poor matching of the whole machine, low level of automation control, poor adaptability, and high labor intensity. For the mobile sprinkler irrigation unit, the size of the moving time and stop time directly affects it and the important hydraulic performance parameters su...
