Embodiment 1

[0064] On the basis of the above embodiments, further, an emitter includes a field head 9, a field branch pipe 10, a field capillary pipe 2, an outflow tree ring 1 and corresponding connecting pipes.

[0065] The field head 9 is placed in the open air near the field operation road 15, and the material is PE pipes and connectors. If the man-made activities of the field operation road 15 are relatively frequent, protective facilities such as fences can be set at the field head 9 periphery. The field head 9 can be connected to the field branch pipe 10 through the second connecting piece, which can be an elbow 12, a standpipe, a tee 6, and the like. The field branch pipe 10 can be connected with the field capillary pipe 2 by a bypass 14 through a connecting piece.

[0066] The field capillary 2 can be connected with the outflow tree ring 1 through the first connecting piece, which can be a tee 6 or a bypass 14 , and a tree ring connecting pipe 7 . Outflow tree ring 1 includes PE...

Embodiment 2

[0071] This embodiment is basically the same as Embodiment 1. For the sake of brevity, in the description process of this embodiment, the same technical features as Embodiment 1 will not be described, and only the differences between this embodiment and Embodiment 1 will be described:

[0072] For ordinary fruit trees or landscape shrubs with young trees, DN50 pipes are selected for field branch pipe 10; DN16 or DN25 pipes can be used for field capillary pipe 2 according to the situation; DN4 pipes are used for outflow tree ring 1; the diameter of outflow tree ring 1 can be distributed according to the crop root system The situation is set to 0.8 ~ 1m; the water outlet 3 is a small-diameter tee 6, and the number of water outlets 3 can be set to 2-3 according to the water demand of the crops.

[0073] Further, according to the planting conditions of the plots within the control range of the water source 11 wells, such as whether the planting crop species is single and the crop p...

Abstract

The invention relates to the technical field of tree irrigation, and discloses an irrigation device. The irrigation device comprises an arc-shaped flow-out tree ring; the flow-out tree ring comprisestwo sections of flow-out small pipes; one end of each of the two sections of flow-out small pipes is connected with a field lateral pipe through first connecting pieces at the same time; the flow-outtree ring is uniformly provided with a plurality of water outlets; and the other ends of the two sections of flow-out small pipes are separated from each other. According to the irrigation device provided by the invention, the flow-out tree ring is arranged as a tail-end flow-out pipe, and the size of the flow-out tree ring and the quantity of the water outlets can be adjusted according to characteristics of species, tree age, root distribution and the like of crops. Water can be directly conveyed to water demand positions of root systems of the crops but not conveyed to root parts of the crops as in a conventional irrigation method, so that open flows on the ground surface can be prevented, and water evaporation can be reduced. The irrigation device is simple in structure, the manufacturing and installation are simple and are easy to operate, the utilization rate of irrigation water can be effectively improved, and the water irrigation time in each time and the labor investment can besaved.

Description

technical field [0001] The invention relates to the technical field of watering trees, in particular to a sprinkler. Background technique [0002] Due to the huge population of our country, although the total amount of water resources is large, the per capita water consumption is very low. The demand for water resources involves almost all aspects of the national economy, such as industry, agriculture, construction, and residents' lives. Severe water shortages will limit the progress of urban modernization, the growth of GDP, and the improvement of residents' living standards. Agricultural water accounts for more than 60% of the total water used in various industries, and agricultural water conservation is imminent. [0003] The existing small tube outflow mode just punches holes in the branch pipe, then installs the dripper, and adds a capillary tube at one end. When watering, the capillary tube is only led to one side of the tree. The capillary is placed near the roots o...
