Water sprinkling device of plant cultivation machine

Abstract

The invention discloses a water sprinkling device of a plant cultivation machine. A water diversion cavity is arranged at the shaft part of a conical body and communicated with the cone tip of the conical body; a plurality of paddles capable of driving water up into the water diversion cavity during the rotation of the conical body are arranged at the cone tip; water sprinkling holes are arranged between the cone bottom and the sidewall of the conical body and / or on the sidewall close to the cone bottom; and the upper part of the water diversion cavity is communicated with the water sprinkling holes. When the water sprinkling device works, the attached water drops can be centrifugally drained by virtue of the surface of the conical body, and moreover, the water drops can be driven in the water diversion cavity by the paddles at the bottom of the water diversion cavity, ascended to the top of the water diversion cavity, and then are sprinkled outwards from the water sprinkling holes. The water-lifting height and water-lifting amount of the water sprinkling device are greatly increased, irrigation time every time the plant cultivation machine works is shortened, and energy consumption is lowered; and moreover, the sprinkled water drops can hardly be blocked by plants which grow tall, and water sprinkling is uniform.

Description

Technical field [0001] The invention relates to a sprinkler, particularly a sprinkler used in a plant cultivation machine. Background technique [0002] The Chinese patent with publication number "102487806A" discloses a sprinkler for plant cultivation machine, such as figure 1 , Which includes a water-carrying platform 1a, above the water-carrying platform there is a cone 4a with a rough surface, the cone is driven to rotate by the driving device 3a, the tip of the cone is inserted below the liquid surface of the water-carrying platform, and the bottom end of the cone is in the liquid Above the surface. When it rotates through the cone, the liquid can flow upwards along its surface to form a liquid film. When the conical liquid flows along the cone surface until the adhesion force with the cone surface cannot overcome the centrifugal force required for rotation, the liquid becomes tiny water particles , And fly out in a parabola along the tangent direction to complete the sprin...

Problems solved by technology

[0003] However, the above-mentioned sprinkling device is limited by the working mechanism, and its water-lifting height and water-lifting capacity are all on the low side, and it takes a long time to sprinkle the plants in the cultivator; and after the plants grow tall, due to the water-lifting height Lower, the sprinkled water droplets are more likely to be blocked by nearby tall plants and cannot reach distant plants, causing plant water imbalance and affecting growth

In addition, the low water lifting height will also cause the water level difference of the water carrying platform adapted to the sprinkler device to be small, and the water carrying platform needs more frequent replenishment of water
