Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.

7th: This is the time limit for sellers to submit their opinions on the “Three Guarantees†of farmers. During the “Three Guarantees†period of validity, for the “Three Guarantees†requirement of the farmers, the seller shall submit handling opinions within 7 days from the date of receiving the request. If the reply is not given within 7 days, or if it is not handled according to the reply, or the treatment does not comply with the regulations, the peasants can handle it according to the regulations. The expenses incurred by the peasants shall be borne by the seller.
Day 40: This is the deadline for repairers to fix the product. During the period of validity of the “Three Guaranteesâ€, the product fails, and the repairer shall remove the malfunction within 40 days from the date of repair and guarantee normal use; if it is not repaired for more than 40 days, the seller shall replace the free of charge for the farmer with the records issued by the repairer. Products of the same specifications and specifications are not allowed to charge any fees.
3 months: This is the "three guarantees" period for the two-stroke gasoline engine.
6 months: This is the "three guarantees" period for the main components of the four-stroke gasoline engine and two-stroke gasoline engine.
9 months: This is the "three guarantees" validity period for single-cylinder diesel engines and small tractors under 18 kilowatts.
1 year: This is the "Three Guarantees" validity period for the main components of the multi-cylinder diesel engine, four-stroke gasoline engine, large and medium-sized tractors larger than 18 kW, and the combine harvester (including corn harvester).
One and a half years: This is the "Three Guarantees" period for the main components of the single-cylinder diesel engine and the main components of the small tractor.
2 years: This is the “Three Guarantees†validity period for the main components of the multi-cylinder diesel engine, the main components of the large and medium-sized tractors, and the main components of the combine harvester (including the corn harvester).
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated Irrigation System
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
Bought a farm machine for these deadlines to remember
On the 2nd and 5th: It limits the repair period for failures of the combine harvester, tractor, rice transplanter, seeder and other products during the busy season in the “Three Guarantees†period of the whole machine; within the service outlets, it is a fault that is easy to repair. Repairs should be removed within 2 days. They are faults that are not easy to repair and should be eliminated within 5 days.
