Description

Technical Field

[0001] This utility model belongs to the field of agricultural irrigation machinery technology, specifically, it relates to an adjustable drip irrigation and fertilization integrated device. Background Technology

[0002] In large-scale farmland cultivation, fixed drip irrigation and fertilization systems are more common. These systems typically consist of a water source, fertilizer tank, pipes, and drippers, delivering water and fertilizer to the vicinity of crop roots through a pre-laid network of pipes. In specific planting areas such as orchards and experimental fields in vegetable greenhouses, there are also some small, mobile fertilization and irrigation devices, mainly used to meet the irrigation and fertilization needs of localized areas.

[0003] On the one hand, integrating fertilization and irrigation can improve the efficiency of water and fertilizer utilization. Drip irrigation precisely delivers water and fertilizer to the vicinity of crop roots, reducing water evaporation and fertilizer loss, thus conserving resources. On the other hand, it reduces labor intensity to some extent, enabling automated or semi-automated irrigation and fertilization operations, thereby improving production efficiency.

[0004] However, current technologies have some significant technical problems. In small planting areas, fixed fertilization and irrigation equipment lacks flexibility and mobility. Once installed, fixed irrigation and fertilization systems are difficult to adjust according to crop growth and different farmland layouts. Secondly, existing mobile drip irrigation devices have fixed drip arm lengths that cannot be adjusted to meet actual needs, making it impossible to achieve adequate drip irrigation coverage in irregularly shaped planting areas. Utility Model Content

[0005] In view of this, the present invention provides an adjustable drip irrigation and fertilization integrated device, which can solve the problem that existing mobile drip irrigation devices cannot adjust the length coverage according to the drip irrigation area.

[0006] This utility model is implemented as follows:

[0007] This utility model provides an adjustable drip irrigation and fertilization integrated device, including a mobile platform. The mobile platform is equipped with a water supply tank and a fertilizer mixing tank. Telescopic drip irrigation components are located on both sides of the front end of the fertilizer mixing tank. Each telescopic drip irrigation component includes a first segment drip irrigation arm and a second segment drip irrigation arm. The first segment drip irrigation arm includes a movable cavity and a first drip irrigation chamber. The second segment drip irrigation arm is movably disposed within the movable cavity. A forward / reverse motor and a drive gear are located at the top of the first segment drip irrigation arm to drive its telescopic movement. A rack that meshes with the drive gear is fixedly connected to the top of the second segment drip irrigation arm. The interior includes a second drip irrigation chamber and a stop-seal plate. One end of the stop-seal plate is fixedly connected to the inner wall of the movable chamber, and the other end is in a sealing sliding fit with a sealing kit on the second drip irrigation chamber. Multiple sets of drip irrigation nozzles are provided at the bottom of the interior of both the first and second drip irrigation chambers. The first and second drip irrigation chambers are respectively connected to the fertilizer mixing chamber via connecting hoses. Each drip irrigation nozzle includes an inner cavity and a downward-swivel nozzle. The downward-swivel nozzle is rotatably connected to the inner cavity, and a sealing ring is provided between the downward-swivel nozzle and the inner cavity. A semi-circular cover plate is provided at the top of the inner cavity, and a semi-circular baffle plate is provided at the top of the downward-swivel nozzle. The baffle plate is used to adjust the drip irrigation flow rate in conjunction with the cover plate.

[0008] The technical advantages of this adjustable drip irrigation and fertilization integrated device are as follows: By setting up a mobile platform, it can flexibly operate in different farmland areas without being limited by a fixed location; by setting up a water supply tank to provide water to the fertilizer mixing tank, it ensures that the fertilizer is fully dissolved and diluted inside the fertilizer mixing tank under the action of the motor and stirring blades; by setting up a telescopic drip irrigation component, it achieves a telescopic structure, powered by a forward and reverse motor, and through the cooperation of a drive gear and rack, it realizes the telescopic movement of the second segment drip irrigation arm, which can be adjusted according to the actual width of the farmland and the planting layout of the crops, ensuring that the drip irrigation range can cover different farmland areas; by setting up a stop-sealing plate and a sealing kit in sliding cooperation, it ensures the sealing of the second drip irrigation chamber and prevents the leakage of water and fertilizer solution; by using evenly distributed drip irrigation nozzles, the water and fertilizer solution is slowly and evenly dripped into the soil around the crop roots, improving the utilization rate of water and fertilizer and avoiding waste. At the same time, drip irrigation can reduce water evaporation and loss, which is beneficial to crop absorption.

This design makes the water supply more controllable and can be precisely adjusted according to the needs of fertilizer mixing and irrigation.

[0016] Furthermore, the top of the water supply tank is provided with an opening for injecting water into it.

[0017] Furthermore, a motor is installed at the top of the fertilizer mixing chamber, and a stirring blade is installed on the output shaft of the motor.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the stirring blades driven by the motor rotate in the fertilizer mixing chamber, so that the fertilizer and water are fully and evenly mixed; the stirring blades can accelerate the dissolution rate of the fertilizer, ensure that the concentration of the water-fertilizer solution is uniform, and improve the fertilization effect.

[0019] Furthermore, the fertilizer mixing silo also has an opening at its top.

[0020] Furthermore, four sets of water pumps are installed outside the fertilizer mixing chamber. The bottom of the water pumps is fixedly connected to the mobile platform, and the output end of each set of water pumps is connected to the corresponding first drip irrigation chamber or second drip irrigation chamber through the connecting hose.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting multiple sets of water pumps externally, the water and fertilizer solution in the fertilizer mixing chamber is transported to the corresponding drip irrigation chamber through the connecting hose; the design of multiple sets of water pumps can improve the delivery efficiency and ensure that the water and fertilizer solution can reach the drip irrigation head quickly and stably; the connecting hose has a certain degree of flexibility, which makes it easy to connect with the drip irrigation arm and can adapt to the extension and retraction movement of the drip irrigation arm.

[0022] Furthermore, a level gauge is installed on the fertilizer mixing chamber, and the level gauge is installed close to the inner wall of the fertilizer mixing chamber, maintaining a distance of 10-20 cm from the stirring blade.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the level gauge against the inner wall of the fertilizer mixing chamber and protruding the top of the fertilizer mixing chamber, the liquid level in the fertilizer mixing chamber can be monitored in real time; maintaining a distance of 10-20cm from the stirring blade can avoid mutual interference between the stirring blade and the level gauge, and the operator can understand the amount of solution in the fertilizer mixing chamber in a timely manner according to the display of the level gauge so as to replenish water and fertilizer in a timely manner.
