Background

Irrigation is a technical measure for supplementing the soil with the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yield, the crops must be supplied with sufficient moisture. Under natural conditions, the water requirement of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, irrigation must be done manually to compensate for the lack of natural rainfall. Irrigation, namely watering the land with water. The irrigation principle is that the irrigation quantity, the irrigation times and the irrigation time are determined according to the water requirement characteristics, the growth stage, the climate and the soil conditions of the medicinal plants, and the medicinal plants are irrigated in a proper time and in a proper amount and reasonably. The main types of the irrigation include irrigation before sowing, seedling-accelerating irrigation, growth period irrigation, winter irrigation and the like. Irrigation methods can be generally divided into traditional ground irrigation, ordinary sprinkling irrigation and micro-irrigation. The ground irrigation mode usually consumes a large amount of water and has low water utilization capacity, so that the ground irrigation mode is an unreasonable agricultural irrigation mode. The common spray irrigation technology is a relatively common irrigation mode in Chinese agricultural production, but the water utilization efficiency of the common spray irrigation technology is not high; modern agriculture micro irrigation usually is driped irrigation, and the water conservation performance of driping irrigation is good, the utilization ratio of water is higher than traditional irrigation mode, but the cost of driping irrigation is higher, and takes place the jam very easily when carrying out the driping irrigation of liquid manure integration, and the water-insoluble fertilizer of drug irrigation can't irrigate through drip irrigation equipment in addition, needs add additional fertilization system.

The existing irrigation equipment can only carry out drip irrigation or spray irrigation, the irrigation mode is single, and the waste of water resources can be caused by the utilization of the spray irrigation equipment; the drip irrigation equipment is utilized, an additional fertilization system needs to be additionally arranged, and the drippers need to be cleaned frequently and accordingly time and labor are wasted.

In order to achieve the purpose, the basic scheme of the invention is as follows: the irrigation device for agricultural planting comprises a water tank, a water pipe communicated with the water tank, a sprinkling irrigation mechanism and a drip irrigation mechanism, wherein a water pump is arranged on the water pipe, the drip irrigation mechanism comprises a water dropper communicated with the water pipe, the lower end of the water dropper is funnel-shaped, a cleaning mechanism is arranged above the water dropper and comprises a cleaning box, a piston is hermetically and slidably connected in the cleaning box, a stop block is movably connected on the inner wall of the cleaning box, the piston is positioned on the stop block, a moving rod is rotatably connected to the lower surface of the piston, a section of lead screw is arranged on the moving rod, a threaded hole matched with the lead screw is formed in the bottom wall of the cleaning box, the lower end of the moving rod penetrates through the threaded hole and extends into the water dropper, a water dropper cover is fixedly connected to the lower end of the moving rod, a gap between the water dropper cover and the inner wall of the water dropper is a flow gap, acid, a pressure release valve is arranged at the upper end of the cavity, a water outlet hole communicated with the cavity is formed in the side wall of the movable rod, the water outlet hole is positioned in the dripper, a first one-way valve which is positioned above the water outlet hole and can be opened towards one side of the water outlet hole in a one-way mode is further arranged in the cavity, a branch pipe is communicated between the cleaning box and the water pipe, a pressure valve is arranged on the branch pipe, a water outlet pipe is communicated between the bottom of the cleaning box and the dripper, and a second one-way valve which can; the sprinkling irrigation mechanism comprises a spray head and a connecting pipe, the connecting pipe is communicated with the dripper, and a gate valve is arranged on the connecting pipe.

The working principle of the basic scheme is as follows: when the drip irrigation is carried out, the gate valve is closed, water in the water tank enters the dripper through the water pipe, and then the water drips out of the dripper through the flow gap between the dripper and the drip cover. When the dripper is blocked by dirt, water cannot drip from the dripper, and meanwhile water is continuously added into the water tank, so that the water level in the water tank gradually rises. The water level in the water tank rises to cause the water pressure in the water pipe to be gradually increased, and the branch pipe is communicated with the water pipe and is provided with the pressure valve, so that the pressure valve is opened when the water pressure in the branch pipe is higher than the preset pressure of the pressure valve; since the branch pipe is communicated with the lower portion of the cleaning tank, water in the water pipe enters the lower portion of the cleaning tank through the branch pipe. The piston is connected in the cleaning box in a sealing and sliding mode, and when the water level in the cleaning box rises to the lower surface of the piston, water can apply upward thrust to the piston, so that the piston is pushed to move upwards.

After the water dropper is cleaned of dirt by the water dropper cover, the water dropper returns to normal work, the pressure applied to the pressure valve is reduced and closed, water in the cleaning box flows into the water dropper through the water outlet pipe, and the piston gradually descends after losing water pressure, so that the water dropper cover is driven to reset.

When the drip cover does not clear up the dirt completely, water level can continuously rise in the cleaning box to drive the piston and continuously rise, make the pressure of piston top can increase gradually, the relief valve can be opened when the pressure of piston top increases to the predetermined pressure that is greater than the relief valve, thereby the acidizing fluid of piston top can pass through in the cavity that the relief valve got into the carriage release lever, then in the drop head flows into from the apopore. The acid liquor enters the dripper to carry out acidolysis on dirt in the dripper, and the dirt is thoroughly cleaned. The dripper resumes normal work after the dirt clearance is accomplished, and the pressure that pressure valve received reduces and closes, and in the water in the clearance case flowed into the dripper through the apopore, the piston dropped gradually behind the water pressure that loses to drive the drip cover and reset, the pressure that the relief valve received reduces and closes simultaneously. Because be equipped with first check valve in the cavity, and first check valve is opened by inlet opening to apopore direction, so the water in the dripper can't get into in the cleaning box from the cavity.

The beneficial effect of this basic scheme lies in: this scheme is through will sprinkling irrigation and drip irrigation the integration setting for this device can change irrigation methods at any time according to the difference of soil moisture and crops, has strengthened the practicality of device. This scheme is through setting up the drip cover into the liftable, not only can adjust the play water flow of water dropper, can also be with the complete closing cap of the lateral wall of drip cover and water dropper simultaneously, realizes will driping irrigation the mode and change into the sprinkling irrigation mode. And the flow velocity of water passing through the upper part of the dripper is large during sprinkling irrigation, so that the water flow can wash the upper part of the dripper to prevent dirt from condensing. According to the scheme, the cleaning box is arranged, so that when the dripper is blocked, the piston can drive the dripper cover to ascend, the flow of the dripper is increased, the dripper is washed by water, and the primary cleaning of the dripper is realized; the piston drives the drip cover to move upwards and simultaneously can drive the drip cover to rotate, so that the dirt in the dripper can be further cleaned through the drip cover; through holding the acidizing fluid in the piston top for can the acidizing fluid flow in the dripper when water pressure is enough big, thereby thoroughly clear up the dirt, through the multiple clearance to the dirt, ensure the unobstructed nature of dripper, guarantee the operating stability of dripper.
