Description

Technical Field

[0001] The invention relates to the technical field of corn planting and irrigation, and in particular to a green high-yield corn water-fertilizer integrated intelligent water-saving drip irrigation system. Background Art

[0002] Among the existing crop planting irrigation technologies, drip irrigation technology is a method of irrigation in which the water is provided with a certain pressure through the pipe network and the drip irrigation belt, and drips slowly and evenly into the soil near the roots of the plants in the form of water droplets through the drippers. Conventional drip irrigation systems are mainly composed of water storage tanks or other water sources, combined with pressurized water pumps and various levels of water distribution pipelines and drippers. They are widely used because of their precise quantification, cost saving and efficiency improvement.

[0003] However, most drip irrigation systems are usually only simple drip irrigation pipelines, lacking corresponding management methods such as water-fertilizer coordination. Some existing integrated water-fertilizer drip irrigation systems usually simply use the water storage tank for water supply to dissolve water and fertilizer simultaneously, integrating irrigation and fertilization for unified water and fertilizer irrigation. There are also such as CN218388636U, a sowing and water-fertilizer integrated device suitable for shallow buried drip irrigation of wheat and corn, which is equipped with an additional independent fertilizer dissolving barrel to cooperate with the drip irrigation system for fertilizer dissolving treatment. However, the existing integrated water-fertilizer drip irrigation system still has some problems in actual use, such as: insufficient mixing of water and fertilizer, which is easy to affect the uniformity after fertilization and also easy to cause pipeline blockage; unscientific irrigation and fertilization management, many foliar fertilizers and pesticides still need to be sprayed manually, and water-fertilizer-drug coordinated management is difficult to apply flexibly; simple drip irrigation pipe network is not convenient for matching with the planting mode of densely planted crops such as intercropping, and simple intensive water and fertilizer surface drip irrigation is also easy to cause large-scale compaction of the drip irrigation ground. In view of this, in-depth research was conducted on the above problems, and this case was produced. Summary of the invention

[0004] The purpose of the present invention is to provide a green and high-yield corn water-fertilizer integrated intelligent water-saving drip irrigation system to solve the problems proposed in the above background technology that the water-fertilizer integrated drip irrigation system is not suitable for the intercropping planting mode of crops, the flexibility of water and fertilizer application is limited, and the water and fertilizer application effect is uneven.

[0005] To achieve the above object, the present invention provides the following technical solutions: a green high-yield corn water-fertilizer integrated intelligent water-saving drip irrigation system, comprising a drip irrigation belt main pipe and a plurality of drip irrigation branches connected to the drip irrigation belt main pipe; An independent rack is provided at the connection between the drip irrigation belt main pipe and the drip irrigation branch pipe, and a fertilizer dissolving barrel is fixedly installed at the independent rack; A weighing box is provided above the fertilizer dissolving barrel for quantitative fertilizer feeding, and a control panel is installed outside the independent frame for controlling the quantitative ratio of water and fertilizer; A pressurized piston cylinder is installed between the fertilizer dissolving tank and the drip irrigation branch pipe to further increase the pressure when applying water and fertilizer; The surface of the drip irrigation branch pipe is evenly distributed with triangular pads according to the corn planting spacing, and the corn is planted in strips, and the drip irrigation branch pipe is located between the corn planting strips; The bottom surface of the triangular pad is supported by the ground, and the inclined surfaces on the left and right sides of the triangular pad are provided with side drip irrigation ports, and side drippers are installed at the side drip irrigation ports for water and fertilizer drip irrigation; A pressure relief port is provided at the top corner of the triangular pad, and a spray head is installed at the pressure relief port for spraying water and fertilizer such as foliar fertilizer.

[0006] Preferably, the corn planting belt is a "2+2" planting pattern of corn and soybean strip intercropping, and the drip irrigation branches are distributed at a distance of 10-25 cm from the plants.

[0007] By adopting the above technical scheme, corn and soybean strip intercropping can effectively increase crop yield per unit area. At the same time, the nitrogen fixation of soybeans also contributes to high crop yield. The relatively dense planting spacing can also facilitate the laying of drip irrigation branches between the planting belts while taking into account the simultaneous irrigation of crops on both sides.

[0008] Preferably, an extension pipe is installed at the side dripper of the triangular pad, and the drip irrigation branch pipe is laid along the side 3-10 cm to the left or right of the middle of the ridge, and the extension pipe is located on the other side of the drip irrigation branch pipe.

[0009] By adopting the above technical solution and coordinating with the extension pipe setting, the drip irrigation branch pipe can be conveniently arranged close to the crop on one side while drip irrigation is carried out on the crops on both sides, so that the spray head above the drip irrigation branch pipe is close to the corresponding crop, which is convenient for flexible adjustment and arrangement of some crops that need more foliar fertilizer when different crops are intercropped in strips.

[0010] Preferably, a servo motor and a reducer are installed on the top of the independent frame, and a driving spindle is provided through the middle of the fertilizer dissolving barrel, and the servo motor drives the driving spindle through the reducer to form a driving structure; A stirring frame is arranged on the outer side of the middle part of the driving main shaft, and the stirring frame is located inside the fertilizer dissolving barrel.

[0011] By adopting the above technical solution, the main function of the driving spindle is to drive the stirring frame to mix and stir in the fertilizer dissolving barrel. The servo motor is used to adjust the control drive and the reducer is used to reduce the speed and maintain stable drive.

[0012] Preferably, a water supply port is provided on the top side of the fertilizer dissolving barrel, and an electromagnetic control valve is installed at the water supply port, and the electromagnetic control valve and the servo motor are both controlled by electrical signals through a control panel.

[0013] By adopting the above technical solution, both the electromagnetic control valve and the servo motor can be controlled and adjusted through the control panel, so that after adding an appropriate amount of fertilizer, the water supply can be adjusted accordingly to adjust the water-fertilizer ratio while performing stable and sufficient stirring and mixing to ensure that the fertilizer is fully dissolved.

[0014] Preferably, a feeding port is provided between the middle of the top of the fertilizer dissolving barrel and the weighing material box, and a feeding auger is provided through the inside of the feeding port; The unloading auger is located at the upper end of the driving main shaft, and the unloading auger rotates synchronously with the driving main shaft.

[0015] By adopting the above technical solution, the driving spindle can be synchronously and cooperatively driven by the feeding auger at the upper end, and the feeding auger located at the feeding port can simultaneously feed the fertilizer stably and evenly, and the equipment can perform synchronous and cooperative stirring to ensure the full and rapid dissolution of the fertilizer.

[0016] Preferably, a water inlet pipe and a water outlet pipe are connected to the upper and lower parts of the front end of the pressurizing piston cylinder respectively, and the water inlet pipe and the water outlet pipe are both tangentially arranged at the connection port with the pressurizing piston cylinder.

[0017] By adopting the above technical solution, the tangentially arranged water inlet pipe and water outlet pipe can form a certain vortex in the pressurized piston cylinder when the water and fertilizer enter the pressurized piston cylinder, which helps to assist in keeping the water and fertilizer in a fully dissolved state and avoid the accumulation of some debris inside the equipment.

[0018] Preferably, the water inlet pipe and the water outlet pipe are both provided with a one-way valve at the connection with the pressurized piston cylinder, and the water and fertilizer in the fertilizer dissolving barrel sequentially pass through the water inlet pipe, the pressurized piston cylinder, the water outlet pipe and the drip irrigation branch pipe to form a one-way passage.

[0019] By adopting the above technical scheme, a one-way water flow path is formed by the cooperation of the one-way valve, which can facilitate the reciprocating motion drive pressurization of the pressurizing piston cylinder. When the movable connecting rod in the pressurizing piston cylinder moves backward, the water and fertilizer in the fertilizer dissolving barrel enter the pressurizing piston cylinder through the water inlet pipe. When the movable connecting rod moves forward, the water and fertilizer in the pressurizing piston cylinder enter the drip irrigation branch pipe through the water outlet pipe.

[0020] Preferably, a piston connecting rod is arranged at the rear of the pressurizing piston cylinder, and a movable connecting rod is arranged at the lower end of the driving main shaft, and a reciprocating driving structure is formed between the movable connecting rod and the piston connecting rod through a connecting rod reciprocating mechanism.

[0021] By adopting the above technical solution, the pressurizing piston cylinder is reciprocatingly driven by the connecting rod driving structure, that is, the driving main shaft is further used to coordinately drive the reciprocating motion of the piston connecting rod. While the water and fertilizer are being applied, stirred and dissolved, the unified driving system is used to coordinate further pressurization, so that the water spray from the spray head at the pressure relief port is convenient for the auxiliary application of some foliar fertilizers, thereby reducing the problem of soil compaction on the ground near the drip irrigation caused by the unified drip irrigation of water and fertilizer.

[0022] Preferably, the main body of the connecting rod reciprocating mechanism is a synchronous movable frame, and a connecting movable groove is transversely opened on the inner side of the synchronous movable frame, and the piston connecting rod is fixed in parallel at the front end of the synchronous movable frame; An eccentric movable shaft is slidably arranged inside the connecting movable groove, and the eccentric movable shaft and the driving main shaft are respectively connected to the head and tail ends of the movable connecting rod.

[0023] By adopting the above technical solution, through the cooperation of the synchronous movable frame and the connecting movable groove structure, it is convenient to maintain the connecting rod transmission structure while synchronizing the piston connecting rods of multiple pressurized piston cylinders through the synchronous movable frame. The specific installation quantity and specifications of the pressurized piston cylinders can be coordinated according to the actual number of drip irrigation branches.

[0024] Compared with the prior art, the invention has the following beneficial effects: the green high-yield corn water-fertilizer integrated intelligent water-saving drip irrigation system improves the drip irrigation pipe network system according to the characteristics of corn dense planting and other crop strip intercropping, can further stabilize the dissolved fertilizer and flexibly apply different water fertilizers or spray foliar fertilizers, meet the flexible fertilization requirements of intercropped crops, improve the utilization rate of water and fertilizer, reduce the waste of water and fertilizer resources, save water and increase efficiency, ensure the high yield and high quality of corn, and help to increase the income of farmers. The specific advantages include: 1. By improving the drip irrigation network system, the irrigation needs of intercropping and close planting can be met. The drip irrigation branch pipe can be used for drip irrigation through the drip irrigation ports on both sides through the triangular pads. It can also be further extended to irrigate different crops on both sides at the same time, and the triangular pads can be used for stable support to effectively reduce the blockage of the drip irrigation ports. At the same time, it ensures that the intercropped crops are green and high-yielding, and can improve the utilization rate of water and fertilizer resources. When using corn and soybean strip intercropping, combined with the nitrogen fixation effect of soybeans themselves, a high-yield intercropping model can be formed to achieve the effect of not reducing corn production and harvesting one more crop of beans, thereby increasing farmers' income.

[0025] 2. At the same time, a spray head is further arranged at the pressure relief port on the top of the triangular pad structure to utilize the original drip irrigation system and to assist the pressurization with the pressurized piston cylinder arranged at the independent frame. Further pressurization can be used to assist in the spraying of part of the foliar fertilizer, so as to achieve the purpose of flexibly applying different water and fertilizers to spray the foliar fertilizer. Combined with the stable water and fertilizer mixture of the fertilizer dissolving barrel, it is convenient for the flexible dissolution and mixing of different fertilizers, so as to achieve the scientific and flexible fertilization effect on crops such as corn.

[0026] 3. The independent frame is equipped with a servo motor that cooperates with the control panel for driving control. At the same time, the servo motor drives the mixing frame, the feeding auger and the movable connecting rod through the driving main shaft. The feeding auger is used to synchronously discharge the material while the mixing frame is stirring, so as to coordinate the stable feeding and accelerate the dissolution of the fertilizer and ensure the full mixing of the fertilizer and water. At the same time, the movable connecting rod further cooperates with the connecting rod reciprocating mechanism to synchronously drive the pressurizing piston cylinder for pressurization to meet the needs of foliar fertilizer spraying. At the same time, spraying from above helps to reduce the problem of soil compaction on the drip irrigation surface caused by simple drip irrigation, and realizes the coordinated operation of synchronous fertilizer dissolution and pressurization. The overall setting is a fertilizer dissolution and pressurization mechanism independent of the original drip irrigation system, which is convenient for the transformation of ordinary non-water fertilizer drip irrigation systems and significantly improves the working efficiency and flexibility of the drip irrigation system.
