Description

Technical Field

[0001] The utility model relates to the technical field of machinery for greenhouse seedling cultivation, in particular to a mobile sprinkler irrigation device for sunlight greenhouse seedling cultivation. Technical Background

[0002] In the greenhouse seedling raising process, water is an essential factor for the growth of seedlings. Sprinkling water on time is the guarantee for the normal growth of seedlings. Usually, the volume of solar greenhouses is large. How to achieve uniform and multiple sprinkling of water for seedlings in such a large space is one of the difficulties in solar greenhouse management.

[0003] In the prior art, most of the watering is done by hand-held sprinkler sprayers. This watering method is inefficient. The speed of manual walking spraying cannot be controlled uniformly, and the watering is uneven, resulting in excessive or insufficient spraying, which affects the growth of seedlings and causes serious waste of human resources. With the development of sprinkler irrigation technology, mobile sprinkler irrigation machinery has been introduced into solar greenhouses to solve the problems of low watering efficiency and uneven watering. However, when uniform sprinkler irrigation is required, the sprinkler irrigation equipment is often required to move at a uniform speed in the solar greenhouse, which results in a large equipment footprint, which easily occupies the already limited space in the solar greenhouse, greatly reducing the usable area in the solar greenhouse.

[0004] In order to solve the above technical problems, the Chinese utility model patent with application number 202221063377.8 announced a cantilever mobile sprinkler irrigation device for a solar greenhouse, which includes a fixed track, a water pipe, a nozzle moving device, a driving device, a reversing walking device and a rope transmission device. The nozzle moving device includes a nozzle bracket, a spray pipe and a nozzle. The nozzle bracket is driven by the driving device to move along the fixed track. The reversing walking device includes a reversing bracket and a water pipe pulley. The reversing bracket is movably arranged on the fixed track. The water pipe pulley is arranged on the reversing bracket. The water pipe is laid along the fixed track and is fixedly connected to the spray pipe after bypassing the water pipe pulley and turning. The rope transmission device includes a first and a second fixed pulley, a movable pulley and a reversing rope. When the nozzle bracket moves, the reversing bracket is driven to move by the rope transmission device. The utility model has a simple structure, uniform irrigation, and saves space.

[0005] However, the above-mentioned prior art still has the following technical problems: in a solar greenhouse, the front, middle and rear parts receive different amounts of light, and the amount of water evaporation is also different, resulting in different water requirements for seedlings in different areas. The nozzle bracket can cover a large area for sprinkler irrigation, but the flow rate of water sprayed by the nozzle set on the nozzle bracket cannot be adjusted, resulting in excessive or insufficient sprinkler water, affecting the growth of seedlings; when the sprinkler water volume is too large, it may even impact the seedlings and cause damage to the seedlings, resulting in economic losses.
