Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation belts, in particular to an embedded cylindrical sponge anti-clogging drip irrigation belt. Background Art

[0002] At present, drip irrigation belts often get clogged in production practice. The main reason is that there are too many impurities in the water source or large particles of fertilizer that are not fully dissolved and are free in the water. In addition to the above internal blockage, the drip irrigation belts will also be blocked due to soil, pollution and the hydrotropism of plant roots. The blockage of drip irrigation belts seriously affects the service life of drip irrigation belts, causing serious waste of resources, and also seriously affects the normal drip irrigation work.

[0003] Most of the drip irrigation belts are used in farmland, and there are also scenarios where they are directly buried underground for deep underground irrigation. However, most of the existing drip irrigation belts are embedded patch type and maze type. Although this method improves the drip irrigation efficiency, the anti-clogging effect is not very significant. Once a blockage occurs, it will affect the normal drip irrigation work, and when the blockage is serious, the entire drip irrigation belt needs to be replaced, resulting in unreasonable waste of resources. Therefore, there is an urgent need for a drip irrigation belt that can prevent blockage, be reused for a long time, and is low in cost. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an embedded cylindrical sponge anti-clogging drip irrigation belt which can prevent clogging, can be reused for a long time and has low cost.

[0005] In order to solve the above problems, the utility model discloses an embedded cylindrical sponge anti-clogging drip irrigation belt, comprising a drip irrigation belt and a drip irrigation head connected together, characterized in that: the drip irrigation head comprises an inner tube and an outer tube nested on the inner tube; water inlet channels are respectively provided at both ends of the inner tube, and a plurality of water inlet holes are evenly distributed in the water inlet channel; a rubber sealing pad is provided on the outside of the water inlet channel; a water collection channel is provided in the middle of the inner tube, and both the water collection channel and the water inlet channel are provided with filter sponges; a water transfer channel is spirally arranged from the water inlet channel to the water collection channel; a U-shaped protruding dripper is provided on the outer tube, and a water outlet hole is provided in the middle of the protruding dripper; trash fences are respectively provided at both ends of the protruding dripper, and filter sponge bars are provided inside the trash fences; a detachable baffle is provided between the tops of the two trash fences at both ends of the protruding dripper.

[0006] The drip irrigation belt and the drip irrigation head are connected together by hot-melt bonding.

[0007] The outer tube cooperates with the rubber sealing pad to be nested on the inner tube to form a drip irrigation head.

[0008] A plurality of the water inlet holes are arranged in a rectangular shape around the water inlet channel.

[0009] The PPI values ​​of the filter sponge and the filter sponge rod are both 40-80 PPI.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] 1. The utility model arranges filter sponges at the water inlet hole of the inner tube and the water collection channel, which can effectively filter tiny impurities and incompletely dissolved fertilizer particles in the water to prevent internal blockage of the drip irrigation belt.

[0012] 2. The protruding dripper of the utility model is U-shaped, and a filter sponge rod is arranged inside it, which can effectively avoid external blockage of the drip irrigation belt caused by external soil, pollution and plant roots.

[0013] 3. In the utility model, a detachable baffle is provided between the tops of the two trash fences along the length direction of the protruding dripper. Even if the dripper is clogged due to the external environment, it can be restored to normal by replacing the filter sponge rod, which greatly reduces the waste of resources.

[0014] 4. The drip irrigation head and the drip irrigation belt in the utility model are combined together by hot-melt bonding technology, which greatly reduces the process difficulty in the production process and reduces the production cost.

[0015] 5. The utility model has the dual function of preventing the drip irrigation belt from being blocked externally and internally during use, is easy to install and use, has low cost and is reusable, and is particularly suitable for farmland drip irrigation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] like Figures 1 to 4 As shown, an embedded cylindrical sponge anti-clogging drip irrigation belt comprises a drip irrigation belt 1 and a drip irrigation head connected together. The drip irrigation head includes an inner tube 2 and an outer tube 3 nested on the inner tube 2; water inlet channels 5 are respectively provided at both ends of the inner tube 2, and a plurality of water inlet holes 4 are evenly distributed in the water inlet channel 5; a rubber sealing pad 8 is provided on the outer side of the water inlet channel 5; a water collection channel 6 is provided in the middle of the inner tube 2, and a filter sponge 9 is provided on the water collection channel 6 and the water inlet channel 5; a water delivery channel 7 is spirally arranged from the water inlet channel 5 to the water collection channel 6; a protruding dripper 13 is provided on the outer tube 3, and a water outlet hole 10 is provided in the middle of the protruding dripper 13; trash fences 14 are respectively provided at both ends of the protruding dripper 13, and a filter sponge rod 11 is provided inside the trash fences 14; a detachable baffle 12 is provided between the tops of the two trash fences 14 at both ends of the protruding dripper 13, so that when pollutants enter the protruding dripper 13 and cause blockage, the pollutants can be cleaned in time or the filter sponge rod 11 can be replaced.

[0023] Wherein: the drip irrigation belt 1 and the drip irrigation head are connected together by hot-melt bonding to form a complete embedded cylindrical sponge anti-clogging drip irrigation belt, which is easy to operate, widely applicable and has excellent bonding performance.

[0024] The outer tube 3 is nested on the inner tube 2 with a rubber sealing pad 8 to form a drip irrigation head. The rubber sealing pad 8 can effectively prevent water leakage and further reduce production costs.

[0025] A plurality of water inlet holes 4 are arranged in a rectangular shape around the water inlet channel 5, so that water can flow in uniformly.

[0026] The PPI values ​​of the filter sponge 9 and the filter sponge rod 11 are both 40-80 PPI. The filter sponge 9 can effectively filter large particles of impurities and incompletely dissolved fertilizer particles in the water; the filter sponge rod 11 can effectively prevent impurities and pollutants in the external environment from entering the dripper and causing blockage.

[0027] The dirt fence 14 is placed at both ends of the protruding dripper 13 to prevent larger pollution particles from directly entering the interior of the drip irrigation head and also to prevent the filter sponge rod 11 from being lost.

[0028] When the dripper is clogged, the impurities can be cleaned or the filter sponge rod 11 can be replaced through the detachable baffle 12, so that the drip irrigation belt can be reused.
