Embodiment 1

[0035] Such as figure 1 and 2 As shown, a light and small semi-automatic drip irrigation pressure difference fertilization vehicle includes a car body, a pressure difference fertilization system, a control metering facility, a PLC controller (not shown) and a power supply 14;

[0036] The car body is a flat car with 4 universal wheels 15, and one end is provided with a handle 12, which is convenient for manual push and pull, and convenient for all-round movement. For reducing weight, the flat car only has a support frame, which is lighter and smaller.

[0037] The pressure difference fertilization system includes a pressure difference fertilization tank body 7, a water inlet pipe and a water outlet pipe. The pressure difference fertilization tank body 7 is fixed on the vehicle body, and the pressure difference fertilization tank body 7 is a fully sealed structure. The material of differential pressure fertilization tank body 7 is plastic material, and is light and anticorrosi...

Embodiment 2

[0047] An automatic drip irrigation pressure difference fertilization method adopts the light and small semi-automatic drip irrigation pressure difference fertilization vehicle of embodiment 1, and when drip irrigation and fertilization are not needed, the fertilization vehicle is kept and stored. When fertilization is required, the following steps are involved:

[0048] (1) In the fertilizer warehouse, add the required liquid fertilizer into the fertilizer bucket, pull the fertilization vehicle to the first fertilization point, and use the fertilization valve installed on the drip irrigation system (some drip irrigation systems do not have a fertilization valve, which can be installed), use The first quick connector connects the water inlet pipe before the fertilization valve, and the second quick connector connects the water outlet pipe after the fertilization valve;

[0049] (2) Input the required fertilizer type and quantity on the display, start the fertilization system, ...

Abstract

The present invention relates to a light and small semi-automatic drip irrigation differential-pressure fertilization vehicle, which comprises a vehicle body, a differential pressure fertilization system, a dosage controlling device, a programmable logic controller (PLC) and a power supply. The differential pressure fertilization system comprises a differential pressure fertilization tank, a water inlet pipe and a water outlet pipe. The differential pressure fertilization tank is fixed on the vehicle body and is of a fully sealed structure. The lower part of the differential pressure fertilization tank is provided with a drain pipe. The lower part of the side surface of the differential pressure fertilization tank is provided with the water inlet pipe, and the upper part of the side surface of the differential pressure fertilization tank is provided with the water outlet pipe. The drain pipe is provided with a first solenoid valve. The water inlet pipe is provided with a water meter and a second solenoid valve. The water outlet pipe is provided with a third solenoid valve. The dosage controlling device comprises a weighing sensor and a plurality of fertilizer barrels arranged on the weighing sensor. A fertilizer delivery pipeline is arranged between the fertilizer barrels and the differential pressure fertilization tank. The fertilizer delivery pipeline is provided with a fourth solenoid valve. According to the technical scheme of the invention, the differential-pressure fertilization can be automatically and intelligently realized. Meanwhile, the entire fertilization process is simple in operation.

Description

technical field [0001] The invention relates to a light and small semi-automatic drip irrigation pressure difference fertilization vehicle and a fertilization method thereof, belonging to the field of agricultural irrigation machinery. Background technique [0002] Drip irrigation and fertilization technology is the characteristic and advantage of drip irrigation, which can produce good economic and ecological benefits. At present, the most common drip irrigation and fertilization device in my country is the differential pressure fertilization tank, which is cheap and easy to operate, and is very popular among farmers. However, in production practice, there are still the following problems in differential pressure fertilization: (1) drip irrigation itself is called the "nobility" in irrigation, and irrigation projects have always hoped to reduce the cost of drip irrigation systems reasonably. Fertilization is not done frequently in production, but currently fertilization tan...
