[0004] However, during the use of the device, it was found that the device consumed a lot of energy when transporting water, which increased the planting cost. In addition, the device was not convenient for automatically recycling the drip irrigation tape, which increased the labor intensity of manual recycling and reduced the convenience of use. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a corn dense planting drip irrigation system which utilizes the power of compressed air to drive the storage device to operate, thereby reducing the energy consumption of corn drip irrigation, reducing the use of groundwater sources, reducing planting costs, reducing the labor intensity of personnel collecting drip irrigation tapes, and improving work efficiency.

The first conveying pipe is connected and arranged at the lower part of the outer side wall of the first tank body. It also includes a collection device, a storage device, a drip irrigation device, an air inlet valve, a first stop valve, a one-way discharge valve, a support ring, a piston and an air pump. The air inlet valve is connected and arranged at the lower part of the outer side wall of the first tank body. The first stop valve and the one-way discharge valve are respectively connected and arranged on the first conveying pipe. The support ring is installed at the lower part of the inner side wall of the first tank body. The piston is arranged to slide up and down inside the first tank body.

When the power device drives the second connecting ring 302 to rotate, the second connecting ring 302 drives the first connecting ring 301 to rotate, so that the first connecting ring 301 drives the winding cylinder 203 to rotate and wind up the drip irrigation belt 207. When the drip irrigation belt 207 needs to be freely unwound, the third connecting ring 306 is driven to move downward by multiple electric cylinders 305, so that the multiple telescopic rods 303 are separated from the first connecting ring 301, improving the operation convenience of the free rotation of the winding cylinder 203.

[0049] Such as Figures 1 to 14As shown in the figure, a corn close planting drip irrigation system of the present invention, when working, collects rainwater through a collection device, and conveys the collected rainwater into the interior of the first tank body 101. In the initial state, the piston 107 is located in the middle of the first tank body 101. When the rainwater in the first tank body 101 is full, the first stop valve 104 is opened, and the piston 107 is pressed to move downward by using the gravity of the rainwater. After the piston 107 moves downward, the air in the lower part of the first tank body 101 is conveyed into the storage device through the first conveying pipe 102 and the one-way discharge valve 105, so that the air is compressed in the storage device. When the piston 107 drops above the support ring 106, the rainwater in the first tank body 101 is pumped and stored through the storage device. After that, the lower part of the first tank body 101 is pressurized by the air pump 108, so that the pressure pushes the piston 107 to move upward and reset. Through multiple reciprocating operations, the air is compressed and stored in the storage device, and the rainwater enters the storage device for storage. When it is necessary to drip irrigate the corn, the storage device is driven to operate by using the power of compressed air.

[0050] The main functions achieved by the present invention are: driving the storage device to operate by using the power of compressed air, thereby reducing the energy consumption of corn drip irrigation, reducing the use of underground water sources, and reducing the planting cost. The drip irrigation belt is automatically recycled through the drip irrigation device, thereby reducing the labor intensity of personnel collecting the drip irrigation belt and improving work efficiency.

[0051] The air pump 108, electric cylinder 305, delivery pump 403, water pump 408, first motor 603 and second motor 703 of a corn close planting drip irrigation system of the present invention are purchased on the market. Those skilled in the art only need to install and operate according to the attached operation manuals, without the need for creative labor of those skilled in the art.

[0052] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
