Drip irrigation technology is the most advanced water-saving technology, especially root drip irrigation, which not only saves water and fertilizer, but also reduces the overgrowth of weeds, diseases and insect pests, makes the soil not compacted and has good air permeability, which is greatly beneficial to the growth of plants. The current drip irrigation device is a project, including a set of water delivery systems such as water storage containers, pumps, valves, filters, main pipes, branch pipes, capillary pipes, and drippers. The layout must be relatively concentrated, the terrain must be relatively flat, and the initial investment is large. The technical requirements are high, so it is difficult to popularize in poverty-stricken areas, especially for individual farmers; in addition, indoor potted flowers and plants that many people in urban families like, sometimes die due to visiting relatives and traveling for a long time without care, and a water-saving drip irrigation device is also needed.

3. Contents of the invention

The purpose of this utility model is to provide a new type of water-saving drip irrigation device, which can automatically supply water to the roots of plants, and has reached the highest level in terms of simple structure, convenient use, low cost and water-saving effect. It can be popularized and applied immediately without changing the existing plant planting conditions.

The utility model adopts a new way of thinking to achieve the above-mentioned purpose: that is, the complex drip irrigation device is divided into parts, and the water supply to many plants is changed from a set of drip irrigation devices to only supply water to the root of one plant. This completely avoids a set of troublesome water pipe network system, and can also be transformed from a large number of discarded old coke bottles (or other similar plastic bottles) in the society, which can greatly reduce the cost and create conditions for popularization.

The structural features of the utility model are as follows: the bottle cap that is threadedly connected with the water storage container is the insertion rod of the water delivery pipe in the center, and the top side of the water delivery pipe has a water outlet hole communicating with the outside; the water storage container is a coke bottle or other similar screw A plastic container with a mouth; and is equipped with an air inlet and an air inlet pipe. It does not need to lay pipes, is not restricted by terrain, and does not need power, and can directly transport water to the roots of plants below the surface.

Compared with the existing drip irrigation device, the utility model has the following significant advantages:

1. The structure is very simple: the utility model consists of a coke bottle (or other similar plastic bottles) plus a bayonet-shaped insertion rod to form a completely independent miniature drip irrigation device. Pumps, valves, and a troublesome water pipe network system are omitted, which greatly simplifies the structure.

2. It is very convenient to use: just fill the utility model with water, insert the bayonet-shaped plunger into the soil near the root of the plant, and it can work without laying pipes or power. The height and location of planting are not affected, so it can be used immediately without farmland transformation. It can be pulled out when drip irrigation is not needed, without affecting field cultivation. According to the speed of the small bubbles on the air intake pipe, you can know the speed of the water outlet and find out whether it is blocked, and then make appropriate adjustments. The transparent coke bottle makes the water level clear at a glance, and the water can be found and replaced in time when it runs out. Because the threads of the large and small cola bottle mouths are the same, it is convenient to use cola bottles of different sizes to meet the needs of different plants; it is also very convenient to insert several more plants with a large water demand. If the water contains nutrient solution, it is convenient to fertilize the roots, and there is very little waste of fertilizer. It is especially suitable for planting large economic plants in arid areas, such as tomatoes, cucumbers, melons and fruits.

3. The cost is particularly low: old Coke bottles can be collected for free or very little money; bayonet-shaped bottle caps, sealing gaskets, air intake pipes, etc. can be made of plastic, and the materials used are very few, so the cost is particularly low. One hundred yuan can meet the needs of a farm family, and it can be used for several years. End-of-life bottles and plungers can still be recycled.

4. Excellent water-saving effect: In addition to the water outlet hole, the utility model has only a very small air inlet hole, which has good sealing performance, and all the water is directly transported to the roots of the plants, avoiding a large amount of evaporation on the ground surface, and making full use of every A drop of water, very little waste.

5. Good economic and social benefits: the use of the utility model in arid regions can significantly increase the yield of crops; and manufacturers of the utility model, due to low cost and huge demand (up to tens of billions), also have considerable profits. The best use of waste Coke bottles is the highest embodiment of its value and is also conducive to environmental protection.

Fig. 2 is a schematic cross-sectional view of the water outlet hole of the insertion rod of the present invention.

5. Specific implementation

The utility model is described in further detail below with reference to accompanying drawing: use coke bottle or other similar plastic containers with screw mouth as water storage container 1, the coke bottle of existing 600-2250ml can satisfy most of needs substantially, certainly also can Retrofit from larger old reservoirs. The purpose of using recycled disposable plastic containers is to greatly reduce the cost of users, and there are as many as tens of billions of disposable plastic containers each year, which are easy for users to collect. The plunger 2 has various functions such as connection, water delivery at the root, and fixation in the soil. There is thread in one end, which is threadedly connected with the coke bottle 1, which is equivalent to a bottle cap; the sealing gasket 6 can guarantee the sealing of the liquid in the bottle. There is a long blind hole in the center of the insertion rod 2, which is the water delivery pipe 2.1, and the top side of the water delivery pipe 2.1 has some water outlet holes 2.2 connected with the outside, which can directly transport water to the roots of plants below the surface; the insertion rod 2. It can be made into different lengths for selection, generally 10-15cm for household potted flowers, and 15-25cm for farmland, or longer. The longer insertion rod has a larger water delivery depth and a better water-saving effect, but the insertion rod is required to be made of a material with better strength. There are 3-6 convex ribs 2.3 on the outside of the plunger 2, which are conical bayonet-shaped, and its purpose is to increase the rigidity of the plunger, and make the plunger firmly inserted in the soil and not easy to topple over. The insertion rod 2 can be inserted into the soil obliquely without affecting the work of the drip irrigation device. It is conducive to making the water close to the center of the plant root, and the general inclination is preferably no more than 30 degrees. The inner bottom of one end of the insertion rod 2 bottle caps has an L-shaped air inlet 2.4 leading to the outside, and the lateral outlet of the air inlet 2.4 is located in a small groove 2.5, which can avoid being blocked by the soil when inserted into the soil; An air intake pipe 3 is also fixed in the air intake hole. The air inlet pipe is very thin, 1.5-2.0mm is enough, so that the outside air has a channel to enter, and the water in the bottle can flow out smoothly. The height of the air inlet pipe is about 1/4-1/2 bottle height. When air bubbles continuously emerge from the small hole of the air inlet pipe, you can grasp the speed of water discharge and find out whether it is blocked, and then make appropriate adjustments. The water outlet hole 2.2 is located in the groove between the convex ribs 2.3, and there is also an impenetrable thin wall 2.6 in the water outlet hole 2.2, and its thickness is about 0.2mm. It can be partially or completely opened with a tool according to the needs. This can change the speed of the water. When the water outlet hole is too large, the hole can also be sealed with wax. The outside of air intake hole 2.4 also can stick part or all with tape paper, makes water seep out with slower speed. The mouth of the water outlet hole 2.2 is trumpet-shaped 2.7, so that the soil is not easy to block it. In order to make the water outlet slow and uniform, water seepage material 4 is also placed in the water delivery pipe 2.1, such as fiber and porous materials such as absorbent cotton and filter paper, under the action of capillary, water can flow out evenly and slowly. The seepage material 4 can also be gauze or filter paper, which is wrapped outside a through pipe 5 and made into a rod shape, one end is inserted in the water delivery pipe 2.1, and the other end is exposed in the water. , when there is a lot of dirt on its surface, it is convenient to take it out for thorough cleaning. Leading pipe 5 can be made of plastics, and its effect is that a part of water can directly reach the bottom of water delivery pipe 2.1 through its endoporus, guarantees the smooth flow of water outlet, and makes softer seepage material 4 have a fixed support. Although the shape of the plunger 2 is relatively complicated, it is most suitable for it to be manufactured by plastic injection molding or metal die-casting. The plunger manufactured by the metal die-casting process has good strength and long service life; while the plunger made by plastic injection can be very cheap.
