Description
Technical field
The utility model is related to a kind of sprinkler with reel, specifically a kind of eccentric swing stepping suitable for gardens sprinkling irrigation is returned
Rolling sprinkler with reel belongs to gardens sprinkling irrigation equipment technical field.
Background technology
In certain region application engineering technology and artistic media, (or mountain, piling and layout of stones, reason are further built by the way that landform is transformed
Water), the beautiful natural environment that forms of plantation trees flowers and plants, the approach creation such as constructing architecture and arrangement garden road and condition of strolling about or have a rest, just
Referred to as gardens, gardens generally include flower garden, private garden, petty street garden, garden, park, botanical garden etc., and gardens serve not only as strolling about or have a rest it
With but also have the function of protecting and improving the environment, energetically facilitation is played to urban afforestation and environmental protection.
Sprinkling irrigation is to be formed water droplet there is pressure water to be sprayed onto in the air using special equipments such as nozzles and fallen to the ground and crop table
The irrigation method in face, irrigation sprinkler are also known as sprayirrigation, sprinkling irrigation unit, that is, special equipment used by spraying.

On water transfer pipe network setting position below face, the pressurized pumping plant of sprinkling irrigation water and water transfer pipe network fixed point spray is carried out by nozzle ejection
It fills, also there are following defects for this traditional sprinkling irrigation mode:
1. needing pre-buried water transfer pipe network during due to gardens construction, not only quantities is huge, but also pre-buried is arranged in ground
Following water transfer pipe network not easy care, breaks down or investigation is more difficult during water leakage situation;
2. the factors such as the shape in gardens plot, ground line gradient, vegetation plantation direction can influence the arrangement of water transfer pipe network, into
And virtually cause the increase of quantities;
3. due to the mode that fixed point is taken to spray, and individually the area coverage of nozzle is limited, therefore need to set suitably
Nozzle combines spacing to avoid sprinkling irrigation dead angle;
4. booster station need to usually be made to be located at the middle position in location with reduce pipeline dosage and aqueduct head loss,
And then investment cost and operating cost are reduced, but often result in needs additional pre-buried setting to pressurize apart from the booster station of water source farther out
Pumping plant hydraulic pipeline, equally not easy care;
5. since the sprinkling irrigation water sprayed from nozzle is influenced by its own gravity factor, can cause during spraying in soil
Horizontal distribution gradually decreased outward centered on nozzle, the tapered structure in section, although suitable nozzle combination spacing can be with
Sprinkling irrigation dead angle is avoided, but still can cause to irrigate the waste of non-uniform phenomenon and water resource.

Eccentric rotational motion is done in movement;The setting of 43 front-rear direction of upper caliper is erected between eccentric swing mechanism 42 and card road 21, is such as schemed
Shown in 7, upper caliper 43 include bayonet part and supporting plate portion, bayonet part include in left-right direction opening setting, be connected to card road 21
On bayonet, the width dimensions of bayonet and the thickness clearance fit in card road 21, supporting plate portion be length direction along the longitudinal direction
The battened construction of setting, the front end in supporting plate portion is fixedly connected with bayonet part, rear end is overlapped on eccentric swing mechanism 42;Lower caliper
44 structure is identical with the structure of upper caliper 43, positioned at the underface of upper caliper 43, and the bayonet of 44 bayonet part of lower caliper is connected to
On card road 21, the rear end in 44 supporting plate portion of lower caliper is overlapped in rack 1.Fortune is eccentrically rotated by control eccentric swing mechanism 42
The dynamic bayonet interval occlusion card road 21 that can realize upper caliper 43 simultaneously drives the whole intermittent rotary of Ka Daoshi reels 2, lower caliper 44
It can prevent Ka Daoshi reels 2 from reversing.
In the storage transition state of non-sprinkling irrigation, sprinkling irrigation PE pipes twine this eccentric swing stepping rollback type sprinkler with reel completely
It is wound on the cylinder of Ka Daoshi reels 2, lower caliper 44 is in the anti-reverse state in occlusion card road 21, at this time can be by pushing and leading
The rear end of machine drawing frame 1 tilts the front support of 1 front end of rack and is detached from ground that transition can be carried out.It sprays in gardens
During operation, the rear end of upper lift rack 1 makes after realizing firm support in the front support insertion ground of 1 front end of rack, first from bayonet position
Upper caliper 43 and lower caliper 44 are removed, then release nozzle supporting mechanism 33 and pulled forward to the position that need to spray, nozzle branch
The rotation of Ka Daoshi reels 2 releases sprinkling irrigation PE pipes during support mechanism 33 moves forward, and upper caliper 43 and lower caliper 44 are clamped again
The pressure water input adapter of 31 input terminal of eddies of water roller box with pressure feed water is tethered after installation and is connect, opens pressure feed water bolt, pressure
Water i.e. enter eddies of water roller box 31 push hydroturbine rotation after through pressure water shaft end input adapter 32 enter sprinkling irrigation PE pipe, most after through spray
First 34 spray realization sprinkling irrigation;The output shaft and eccentric swing mechanism of eddies of water wheel-speed regulating change box 41 are driven in hydroturbine rotary course successively
42 rotations, during eccentric swing mechanism 42 is eccentrically rotated, eccentric swing mechanism 42 drives upper caliper 43 when being eccentrically rotated uplink
Rear end move up, when clearance fit upper caliper 43 bayonet because 43 rear end of upper caliper move up deflection due to be engaged card road 21 when,
Upper caliper 43 and Ka Daoshi reels 2 are that whole moved up by the drive of eccentric swing mechanism 42 makes Ka Daoshi reels 2 around rotation of reel axis
Axle center rotation realize backrush, and in 2 reeling up process of Ka Daoshi reels because 44 its own gravity Shi Ka roads 21 of lower caliper relative to
The bayonet of lower caliper 44 does sliding relative movement, i.e. lower caliper 44 does not follow 2 backrush of Ka Daoshi reels, when being eccentrically rotated downlink on
Clamp 43 are because its own gravity follows eccentric swing mechanism 42 to be snapped down to initial position along card road 21, and lower caliper 44 is in occlusion and blocks
Road 21 prevents the state that Ka Daoshi reels 2 reverse;And so on, the stepping backrush of Ka Daoshi reels 2 is realized, when nozzle supports machine
Structure 33 retracts to entire sprinkling irrigation process is completed during initial position, closes pressure feed water bolt.
Since the rear end of upper caliper 43 is overlapped on eccentric swing mechanism 42, upper caliper 43 is from eccentric oscillating machine in order to prevent
Improper on structure 42 comes off, and as further improvement of the utility model scheme, the eccentric swing mechanism 42 is equipped with
