Description

Alternate drip irrigation planter for potted plants

technical field

The invention relates to an alternate drip irrigation planter for potted plants, which belongs to the technical field of agricultural tools.

Background technique

Drip irrigation has been widely promoted and adopted due to its outstanding water-saving effect. The irrigation water utilization rate of drip irrigation can reach 95%. Drip irrigation can be used not only for the irrigation of field economic crops such as fruit trees and vegetables, but also for the irrigation of greenhouses and potted plants. wait. With the development of technology, potted drip irrigation plants are widely used in crop seedling cultivation, flower planting, scientific research, soil testing formula and so on. There are various structural forms and drip irrigation designs for potted plant drip irrigation, but as far as the current potted plant drip irrigation is concerned, there is still a problem to be improved aspect the drip irrigation planter.

The main problems of the existing potted drip irrigation system have the following aspects:

1. The dripper is close to the basin wall, and the water flow mainly relies on gravity to flow down the basin wall during the drip irrigation process.

2. The dripper is set in the pot or in the center, or the dripper is exposed outside for a long time, which is very vulnerable to the influence of the external environment. For example, the emitter is directly in contact with the soil, and in a short period of time, various sediment particles, organic matter adhesion, acidity Or chemical condensate in an alkaline environment, etc. will cause scaling, blockage or even damage to the dripper. In severe cases, the entire system will not work properly or even be scrapped.

3. Existing drip irrigation systems for potted plants are often connected with a large number of capillaries or microtubes inserted into the soil in the pot, which is not beautiful, and it is impossible to implement alternate irrigation, especially when replacing soil or plants in the pot, it brings great inconvenience.

Contents of the invention

In view of the above problems, the technical problem to be solved by the present invention is to provide an alternate drip irrigation planter for potted plants.

An alternate drip irrigation planter for potted plants of the present invention, which includes a circular pot edge, a three-way adjustment switch, a retractable dripper, an external pipeline connection end, a rotating central axis, a rubber connected water stop, an internal capillary, a cock valve, a rubber waterproof Leakage stop, three-way flow channel, dripper water filter hole, dripper snap ring, force spring, emitter, emitter telescopic hole. The connecting end of the external pipeline can rotate up and down around the central axis of rotation; the hollow inside of the circular basin is a capillary for water delivery, and the telescopic dripper is fixedly installed on the capillary for water delivery; The connecting water stop connects the connecting end of the external pipeline and the three-way flow channel, and the rubber leak-proof water stop prevents the plug valve from leaking.

As a preference, in the alternate drip irrigation planter for potted plants, the retractable dripper protrudes outward under working pressure conditions; when there is no pressure, the stressed spring bounces the emitter back to the emitter telescopic hole, avoiding the emitter from causing damage to the emitter. damage.

At the same time, considering the different irrigation methods, three-way adjustable cock valves are installed at both ends of the pot edge to flexibly adjust the irrigation method of drip irrigation. Similarly, single-pot drip irrigation or multi-pot series drip irrigation can be realized by adjusting the plug valve and the connection end of the external pipeline.

Compared with the existing potted drip irrigation technology, the present invention has the following beneficial effects:

1. Make full use of the hollow structure on the upper edge as the drip irrigation water pipeline, without changing the complexity of the structure, making the structure beautiful and practical.

2. The retractable sprinkler can ensure that the drip head is not damaged or damaged, and the service life of drip irrigation is improved. the

3. The dripper is higher than the soil in the pot, avoiding the adhesion of sediment, etc. on the dripper; the dripper protrudes under the working pressure, and the drip irrigation water drips into the soil in the pot, and it is evenly dispersed by the capillary force of the soil, avoiding the flow of water Directly down the basin wall.

4. The three-way cock valve can be used to adjust the irrigation method of drip irrigation arbitrarily, which can realize single-pot drip irrigation or multi-pot series drip irrigation, which greatly improves the flexibility of drip irrigation.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention is described below through specific embodiments shown in the accompanying drawings. It should be understood, however, that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

As shown in Figures 1-3, this specific embodiment adopts the following technical solutions: it includes a circular basin edge 1, a three-way adjustment switch 2, a retractable dripper 3, an external pipeline connection end 41, a rotating central axis 42, and a rubber connection Water stop 43, internal capillary 44, cock valve 45, rubber leak-proof water stop 46, three-way flow channel 47, dripper filter hole 31, dripper snap ring 32, force spring 33, sprinkler 34, sprinkler telescopic Hole 35.

The connecting end of the external pipeline can be rotated up and down around the central axis of rotation, that is, it can be connected or closed; the inside of the circular basin is a water delivery channel, and the channel is inlaid with telescopic drippers at a certain distance, and the dripper filter holes can effectively prevent impurities from entering the irrigation water The dripper is blocked by the device; the rubber is connected to the water stop to connect the external pipeline and the three-way flow channel, and the rubber is leak-proof and water-proof to prevent the cock valve from leaking.

Further, the telescopic drip head of the alternating drip irrigation planter protrudes outward under the working pressure condition, and when there is no pressure, the stressed spring bounces the emitter back to the telescopic hole of the emitter. The three-way cock valve can adjust the irrigation method of drip irrigation, which can realize single-pot drip irrigation or multi-pot series drip irrigation.

The working principle of this specific embodiment is: horizontally lift the connecting end of the external pipeline (41) and connect the water delivery pipeline, adjust the three-way cock valve (2) to determine the drip irrigation method, when the drip irrigation system is in normal operation, the pressure inside the pipe increases, The retractable dripper (3) protrudes outwards through the telescopic hole (35), and water irrigation starts. During the drip irrigation process, the water filter holes (31) effectively filter impurities that have not been removed in the water to ensure the normal operation of the emitter. After the irrigation is completed, the internal pressure of the system decreases, and the emitter (34) naturally retracts under the action of the stressed spring (33) to prevent damage to the dripper.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have Variations and improvements are possible, which fall within the scope of the claimed invention. The protection scope of the present invention is defined by the appended claims and their equivalents.
