Description

Multifunctional crop drip irrigation system

Technical Field

The invention relates to the technical field of agricultural drip irrigation, in particular to a multifunctional crop drip irrigation system.

Background

Drip irrigation is one of the most water-saving irrigation techniques for farm irrigation so far. However, the drip irrigation technology is high in price and is called as 'expensive technology' once, and in recent years, with the wide application of the drip irrigation tape, the 'expensive technology' is not expensive any more and can be completely applied to common field crops.

Soil remediation is a technical measure to restore normal function to contaminated soil. In the soil remediation industry, the existing soil remediation technologies can be more than one hundred, the common technologies can be more than ten, and the existing soil remediation technologies can be roughly divided into three methods, namely physical methods, chemical methods and biological methods. Soil is originally a natural accommodation place and a purification treatment place of various wastes, soil accepts pollutants, does not indicate that the soil is polluted, and indicates that the soil is polluted only when various pollutants accommodated in the soil are excessive and influence and exceed the self-purification capacity of the soil, so that the soil has harmful influence on hygiene and epidemiology. The existing cultivated land in China is nearly 1/5 polluted to different degrees, the polluted soil can cause the yield reduction of crops, and even the pollutant in agricultural products can exceed the standard, thereby further harming the human health. Therefore, it is necessary to properly manage and repair the system so as to make it reasonably usable.

Bioremediation, a controlled or spontaneous process for the remediation of contaminated environments or the elimination of contaminants in environments by the catalytic degradation of organic contaminants by organisms, particularly microorganisms. The microbial repairing technology is mainly used for degrading organic pollutants in soil by converting and degrading the pollutants through the metabolism of the microorganisms, indigenous bacteria, foreign bacteria and genetic engineering bacteria on the pollutants.

The specific working process of this embodiment is as follows:

1) a drip irrigation procedure: starting the water pump 1, pumping water to the filter 3, enabling the filtered water to enter the multifunctional flow dividing device 4, when the soil treatment function is not started, the walking device 405 is not started, the sealing plate 4010 is positioned below the upper connecting hole due to the pushing of the first spring, the upper connecting hole is blocked, meanwhile, the movable insertion tube 407 is positioned in the connecting sleeve 402 due to the gravity, and at the moment, water flows out of the lower connecting hole and enters the drip irrigation capillary 5 to carry out drip irrigation on crops;

2) and (3) a soil microbial treatment process: when the drip irrigation process is carried out, the soil improvement function is started, the motor 4054 rotates to drive the gear 4053 to move along the rack 404, the walking device 405 further moves along the sliding rail plate 403, in the moving process, the walking device 405 stays for a period of time T2 after running to an upper connecting hole through a control circuit, at the moment, because the first permanent magnetic ring 4056 is close to the permanent magnetic slide block 408, the interaction force is increased, the first permanent magnetic ring 4056 can drive the permanent magnetic slide block 408 to move together, and further the sealing plate 4010 is pushed to move together until the walking device 405 stops at the upper connecting hole, the permanent magnetic slide block 408 is positioned in the middle of the upper connecting hole, at the moment, the sealing plate 4010 is separated from the upper connecting hole, meanwhile, the first permanent magnetic ring 4056 is coaxial with the movable insertion tube 407, the magnetic force of the first permanent magnetic ring 4056 attracts the magnetic sleeve 4074 to move upwards against the gravity, and then the whole movable insertion tube 407 is inserted into the upper connecting hole, and the bacteria liquid box 406 is directly communicated with the connecting sleeve 402 below, the bacteria liquid does not enter the trunk pipe 401 so as to prevent the soil at other positions from being polluted, at the moment, the water flow pushes the water wheel 4078 to rotate, and then the water pumping blade 4076 is driven, so that the movable insertion tube 407 generates suction, microorganisms in the bacteria liquid box 406 are discharged through the drip irrigation capillary 5 to treat the soil, after the time of T2 staying, the motor 4054 is restarted, the walking device 405 continues to move to the next drip irrigation capillary 5, meanwhile, the first permanent magnetic ring 4056 is far away from the permanent magnetic slider 408 and the magnetic sleeve 4074, so that the sealing plate 4010 blocks the upper connecting hole again, and the movable insertion tube 407 falls into the connecting sleeve 402 again to continue to perform drip irrigation.

3) Automatic selection of bacterial liquid: after the bacteria liquid box 406 moves to the upper part of the upper connecting hole, the distance between the magnetic sheet 4011 and the second permanent magnetic ring 4068 is the shortest, at the moment, due to the different magnetic forces of the magnetic sheet 4011, the sliding chamber 4067 longitudinally moves by different distances, the magnetic sheet 4011 with the smallest magnetic force can only attract the sliding chamber 4067 to the uppermost liquid storage bin 4063, the magnetic sheet 4011 with the strongest magnetic force can attract the sliding chamber 4067 to the lowermost liquid storage bin 4063, different magnetic sheets 4011 can be connected according to the soil condition of each drip irrigation capillary 5, and after the bacteria liquid box 406 moves to the drip irrigation capillary 5, proper bacteria liquid can be selected for treatment.
