Embodiment 1

[0056] figure 1 It is a water-saving drip rod with a fixed-slit air inlet channel and a stepped hole outlet valve.

[0057] The water-saving drip rod 2 is composed of the nut 1m part and the insertion rod cg part (see Figure 5 ), the screw cap 1m is threadedly connected with the bottle mouth of the bottle-type water storage container 1, and can be used as an air intake valve to adjust air intake; one or several air intake slits f are arranged on the inner bottom plane dm of the nut, and its depth is practical The top is very shallow, about (0.08-0.2) mm. When the thread is tightened firmly, because softer plastics (such as high-pressure polyethylene) can be deformed, about 50% of the gap will change, and the dripping speed can be adjusted. There is a deep hole in the insertion rod cg, which is the water delivery pipe ssg, and the water outlet holes csk are located on both sides (2-6) of the top of the water delivery pipe ssg. Because plastics are cheap, and production effic...

Embodiment 2

[0061] figure 2 It is a water-saving drip rod with a wedge-shaped gap for the air inlet channel, an inner labyrinth water outlet channel and a simple water outlet valve. It is characterized in that the water-saving drip rod 2 screw cap 1m inner bottom plane dm is not completely perpendicular to the axis, but is inclined at a small angle (1 / 50-1 / 100), and is combined with the bottle mouth of the bottle-type water storage container 1 The end faces form a wedge-shaped gap xf. When the screw thread is tightened, due to plastic deformation, the wedge-shaped gap xf is squeezed and gradually decreases, and finally it is completely closed or only one remaining gap remains; when the thread is loosened, the wedge-shaped gap xf increases. This intake valve can continuously adjust the gap, and the variation range is large. Tests have shown that large adjustments from one drop per minute to one drop per second can be achieved using the intake valve. It does not add any parts, and its s...

Embodiment 3

[0066] image 3 It is a water-saving drip rod with elastic washer inlet channel, outer labyrinth outlet channel and screw hole outlet valve. It is characterized in that a relatively soft elastic washer 6 is placed between the inner bottom plane dm of the nut and the bottle mouth, and the elastic washer 6 is provided with an air inlet groove qc, or an air inlet gap f is arranged on the inner bottom plane dm of the nut . The change of the size of the air intake slit is accomplished by the deformation of the elastic washer 6 . The advantage of this technical solution is that there is no need to impose strict requirements on the size of the contact surface of the air intake slit. As the thread is tightened and the pressure increases, all the slits or grooves will gradually become smaller. Elastic washer 6 can be made of elastic good plastics (such as silica gel).

[0067] In order to normally drip water when the water is particularly turbid, the present invention is also provid...

Abstract

The invention discloses a non-clogging bottle type root drip irrigation device with adjustable speed, comprising a bottle type water storage container and a water-saving drip stick provided with a nut cap, an inserted link, a water delivery pipe, a water outlet, an air inlet channel and a water outlet channel, wherein the air inlet channel is formed by utilizing a gap between the nut cap and threads at a bottle mouth, the size of an air inlet gap is changed through the tightness of the threads to form an intake valve, and a labyrinth type water outlet channel and a water outlet valve are additionally arranged. Water is directly delivered to plant roots under earth surface by the non-clogging bottle type root drip irrigation device, dripping speed can be drastically adjusted, and the non-clogging bottle type root drip irrigation device can not be clogged when muddy water is used, and also has the performance of automatically adjusting the dripping speed according to dryness and wetnessof soil. By using the non-clogging bottle type root drip irrigation device, only the plant roots are irrigated, most scientific precise irrigation can be implemented according to needs of plant growth, and water-saving high yield can be achieved in arid areas. The non-clogging bottle type root drip irrigation device is an independent irrigation system which does not need laid pipelines or electricity, is flexible in use, and has irreplaceable advantages in increasing the survival rate of sapling in afforestation and automatic irrigation for flowers and grass planted at home.

Description

technical field [0001] The invention relates to a plant root drip irrigation device, in particular to a bottle-type root drip irrigation device with adjustable speed and no clogging. Background technique [0002] Due to the excessive emission of greenhouse gases, the earth's climate is abnormal, and droughts or mega-droughts occur frequently everywhere. Although the Chinese government has invested heavily in large-scale water transfers in an attempt to solve the drought problem, the utilization rate of water in our country is extremely low. It takes about 1 ton of water to convert 1 kilogram of grain. Saving irrigation water is an urgent problem that needs to be solved. [0003] At the beginning of 2010, there was a severe drought in Southwest my country. There was no rain for 8 months, the bottom of the lake was cracked, the trees were withered and yellow, and people's production and life were in trouble. Zhu Changguo, secretary of Lengdong Village in Guizhou Province, cre...
