For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing
Type embodiment is described in further detail.
First aspect, this utility model embodiment provides and a kind of can be used for buried open flows channel type rotary nozzle, as
Shown in accompanying drawing 1, this rotary nozzle includes the buried mechanism 1 being connected with groundwater supply pipeline, and axially slidably places
Sprinkling irrigation mechanism 2 in buried mechanism 1, as shown in Figure 1, this sprinkling irrigation mechanism 2 includes: water inlet pipe 201, turntable 202, connection
Post 203, spin nozzle 204.The most as shown in Figure 2, this spin nozzle 204 includes multiple arc pipe 2041 and multiple cone
Shape baffle plate 2042, the sidewall of arc pipe 2041 is provided with the arc opening 20411 of a longitudinal direction along direction, axis, so that
The inner chamber of arc pipe 2041 forms open runner.The closed combination in circumferentially direction, bottom of multiple arc pipes 2041, with
Forming the conical lower portion of spin nozzle 204, the conical lower portion at this spin nozzle 204 arranges a longitudinal jet orifice simultaneously.Many
The top of individual arc pipe 2041 radially dissipates from the conical lower portion of this spin nozzle 204, each arc pipe 2041
Predetermined angular is distorted, current are formed eccentric pushing power, adjacent two arc pipes in open runner around equidirectional
Connect between the side wall ends of 2041 and have one conical baffled 2042.
Turntable 202 is rotatably mounted around water inlet pipe 201 top, and the lower end of multiple connection posts 203 is fixed on turntable
On the end face of 202, upper end is fixed on the bottom surface of conical baffled 2042, longitudinal jet orifice of this swivel nozzle and water inlet pipe 201
Upper orifice relative, meanwhile, water inlet pipe 201 is connected with underground water inlet pipe 201 road by buried mechanism 1.
The open flows channel type rotary nozzle that this utility model embodiment provides, its 2, mechanism of sprinkling irrigation when state is irrigate in non-spray
In buried mechanism 1, and it is integrally located at below arable layer.When spray state time, current will successively by groundwater supply pipeline, enter
Longitudinal jet orifice injection that water pipe 201, the conical lower portion of spin nozzle 204 are arranged, with the soil of wetted perimeter, and passes through water
Stream institute is with pressure to be tried hard to recommend dynamic sprinkling irrigation mechanism 2 and moves upward in buried mechanism 1 until being exposed to earth's surface, and then carries out operation of spraying.
