specific Embodiment approach

[0019] Mechanical mobile type alfalfa root cap micro-sprinkler irrigation device of the present invention, its preferred embodiment is:

[0020] It includes a plurality of branch pipes leading down from the main water supply pipe of the sprinkler irrigation machine, a water inlet valve is provided at the end of each branch pipe, and the water inlet valve is connected to a water distribution pipe, and a plurality of vertical pipes are arranged on the water distribution pipe. The end of the vertical pipe is provided with a balance pipe, and the lower end of the balance pipe is provided with a micro spray head.

[0021] The pipe diameter of the water distribution pipe is the same as that of the branch pipe, the branch pipe and the water distribution pipe are connected by a straight tee, and plugs are provided at both ends of the water distribution pipe.

[0022] The material of the water distribution pipe is hard polyvinyl chloride pipe, stainless steel pipe or galvanized steel p...

specific Embodiment

[0041] Such as figure 1 As shown, the root cap micro-sprinkler irrigation device diverts water from the main water supply pipe 1 of the sprinkler irrigation machine, and is transported to the water distribution pipe 7 and the vertical pipe 6 of the root cap micro-sprinkler irrigation device of the present invention through the branch pipe 2 . Every span of the sprinkler is realized by driving wheel 3 to rotate or walk on the ground 5, and the original structure 4 of the sprinkler remains unchanged.

[0042]The root cap micro-sprinkler irrigation device of the present invention is represented by a set, and multiple sets of root cap micro-sprinkler irrigation devices can be configured on each span of the sprinkler truss according to the original nozzle spacing, except for the tail spray guns of some central pivot type sprinkler irrigation machines. The root and crown micro-sprinkler irrigation device configured is equal to the number of original nozzles. For example, a 7-span c...

Abstract

The invention discloses a mechanical moving type alfalfa root cap microspray irrigation device, which comprises a plurality of branch pipes introduced from a main water supply pipe of a spray irrigation machine, wherein the tail end of each branch pipe is provided with a water inlet valve, the water inlet valve is connected with a water distributing pipe, a plurality of vertical pipes are arranged on the water distributing pipe, the tail end of each vertical pipe is provided with a weight balancing pipe, and the lower end of the weight balancing pipe is provided with a microspray head. The irrigation water can be conveyed into an alfalfa root cap layer through the vertical pipes for realizing the near ground spraying, and the evaporation loss of the moisture in the air and the interception evaporation loss of the alfalfa cap layer are avoided, so the utilization efficiency of irrigation water is greatly improved, and the device has a better water-saving effect than a center support shaft spray irrigation machine or a transverse moving type spray irrigation machine.

Description

technical field [0001] The invention relates to a water-saving irrigation device, in particular to a mechanically movable alfalfa root cap micro-sprinkler irrigation device. Background technique [0002] Forage or alfalfa production is an important basis for the development of the dairy industry. To completely solve the safety problem of the dairy industry, we must start with the production of high-quality forage. Irrigation is an essential link in large-scale forage or alfalfa production. In arid and semi-arid areas, water resources are extremely scarce, and natural precipitation is insufficient to meet the needs of pasture growth. Forage production or alfalfa planting is almost entirely dependent on artificial irrigation. [0003] In the prior art, in the production of pasture or alfalfa in arid and semi-arid areas, central pivot type electric sprinklers or translational sprinklers are mainly used for irrigation. [0004] The central pivot irrigation machine (also known a...
