Description

Technical Field

[0001] The invention relates to the technical field of drip irrigation, in particular to a bidirectional drip irrigation system for planting Dendrobium officinale or roxburghii. Background Art

[0002] Drip irrigation is a technology that uses plastic pipes to deliver water to the roots of crops through orifices or drippers on a capillary tube with a diameter of about 10 mm for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-scarce areas, with a water utilization rate of up to 95%. Drip irrigation has a higher water-saving and yield-increasing effect than sprinkler irrigation, and can be combined with fertilization to increase fertilizer efficiency by more than double. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for irrigation of field crops in arid and water-scarce areas. However, the drip irrigation system is usually set up on the ground with soil to irrigate crops. Due to the influence of weather or natural growth of crops, the soil is scattered or loosened, causing the dripper to be blocked, affecting the irrigation effect. In addition, the water stored in the liquid storage tank in the drip irrigation system may not meet the requirements. The water may be mixed with impurities such as fallen leaves, dead branches or stone particles, which affects the transmission of water in the pipeline. Summary of the invention

[0003] In view of this, the present invention provides a bidirectional drip irrigation system for planting Dendrobium officinale or Anoectochilus roxburghii to solve the technical problem that the drip irrigation emitter is easily blocked during the drip irrigation process.

[0004] The purpose of the present invention is achieved through the following technical solutions:

The present invention adopts a bidirectional flow channel design, wherein water flows in opposite directions converge in the drip irrigation device, and the impact force between water flows in different directions generates a large instantaneous kinetic energy, so that the water in the water flow and the nutrient solution attached thereto can be more fully mixed before being irrigated to the root of the crop, and furthermore, the kinetic energy generated by the impact of the bidirectional water flow can act on the anti-blocking device to promote its operation. The liquid in the drip irrigation device always remains active during drip irrigation. When the soil blocks the dripping port on the drip irrigation device, it can also impact the dripping port to a certain extent to make it pass through and avoid blockage. In addition, the rotating shaft is rotatably connected to the dripping box through the bearing, and the water flow in the forward guide pipe and the reverse guide pipe impacts the stirring blades on both sides of the rotating shaft respectively. The stirring blades also play a role in stirring the liquid in the dripping box while rotating, so that the liquid is mixed more evenly.

[0007] Furthermore, the impurity removal floating block is provided with a plurality of through holes, and a soft brush is provided on the side of the impurity removal floating block in contact with the liquid in the tank and the inner wall of the through hole.

The filter box is used to further filter impurities in the liquid in the tank to prevent the liquid from scaling when flowing through the pipeline, wherein the diverter plate diverts the liquid so that the liquid can fall evenly on the filter plate to achieve uniform filtration.

[0009] Furthermore, a locking valve is provided between the filter box and the first liquid storage tank or the second liquid storage tank. The locking valve is used to control the liquid delivery amount. The user can adjust the liquid delivery amount according to actual conditions, and can also start or interrupt liquid transmission by opening or closing the locking valve.

[0011] Furthermore, there are multiple dripping grooves, and the multiple dripping grooves are arranged in a concentric annular shape. The annular dripping grooves make the dripping process more uniform and less prone to clogging.

[0012] Furthermore, a brush is provided at the bottom of the stirring blade, and the brush is in contact with the dripping groove. The brush on the stirring blade also cleans the dripping groove when rotating, so the dirt attached to the dripping groove will be brushed off by the brush to avoid blocking the dripping groove, thereby realizing the anti-blocking function on the dripping box.

[0013] Furthermore, a baffle is fixedly provided on the inner wall of the drip box, and the baffle is two and arranged oppositely, and the baffle is located between the forward flow guide pipe and the reverse flow guide pipe. The baffle is used to block the water flow between the forward flow guide pipe and the reverse flow guide pipe to a certain extent, reduce the mutual interference ability between the two, improve the driving ability of the water flow on the stirring blade, and reduce the influence of water flow in different directions on the stirring blade.

[0014] Furthermore, the forward flow guide pipe and the reverse flow guide pipe are arranged in parallel.
