Abstract

The utility model provides a centrifugal water sprayer used for watering the plant in the farmland and garden, belonging to agricultural machinery. The utility model is composed of impellers, a water storage chamber, an electric motor, and a frequency converter. By utilizing the vacuum degree formed by the centrifugal force generated by the rotation of the impellers, the water is sucked out from the water storage chamber and swung in the air, forming artificial rain and spraying and watering the crop, turf, flower, etc. The utility model has large water spraying area, and regulates the speed of rotation of the electric motor by the speed control elements of the frequency converter, sliding resistor, controllable silicon, etc., making the water spray radius realize the automatic regulation from big to small, and increasing the spraying quality and the utilization rate of the water resources.

Description

Centrifugal sprinkler

Affiliated technical field

The utility model relates to a kind of agricultural mechanical facilities of irrigation and drainage that are used for the farmland pouring, is suitable for centrifugal sprinkler continuous to crops or that spray in the piecewise.

Background technology

Existing agricultural sprinkling machine generally is made up of three parts such as water supply part, hydraulic pipeline and sprinklers.By hydraulic pipeline water pump is drawn up the water that comes and give sprinkler, and be ejected into the place that needs irrigation after making water fogging.For improving the quality and the efficient of pouring, need a lot of shower nozzles are installed on a kind of irrigation sprinkler or in a kind of sprinkling irrigation system, cause these sprinkling machine profiles huge, complex structure, be not suitable for frequent change place and carry out operation, make a big chunk farmland can not realize water-saving irrigation.

Summary of the invention

Should not make the deficiency of strange land use flexibly in order to overcome existing sprinkling machine, the utility model provides a kind of centrifugal sprinkler, this centrifugal sprinkler can not only uniformly large-arealy eject water in the crops that need water, and can change operating location easily, make more crops realize water-saving irrigation.

The technical scheme that its technical problem that solves the utility model adopts is: on shell, terminal pad, electromotor, the retaining chamber is to connect together by bolt, impeller is assembled on the motor reel by another bolt, and utilizes two corresponding gap locations of oil sealing sealing.Impeller rotation after the electromotor energising, the vacuum of leaning on the formation of place, impeller suction is with water sucking-off from the retaining chamber, the centrifugal action that produces when utilizing the impeller high speed rotating becomes the sprinkling irrigation of pumping up water of the kinetic energy of water and pressure energy to mechanical energy, and pass through the adjusting of electromotor velocity and moving to the horizontal and vertical position of centrifugal sprinkler, reach evenly the purpose of large tracts of land sprinkling irrigation crops.

The beneficial effects of the utility model are, centrifugal sprinkler can be fixed on a location, by frequency converter, the rotating speed of adjusting electromotor such as controllable silicon is controlled the size of water spray radius, finish sprinkling irrigation to local location crops, centrifugal sprinkler can be installed in the sprinkling irrigation of doing on the motor vehicle in advancing again, thereby finish sprinkling irrigation the large tracts of land crops.

Embodiment

As shown in Figure 1, centrifugal sprinkler is by impeller (11), electromotor (13), retaining chamber (12), and terminal pad (2), shell (1), and the frequency converter that does not mark among the figure or slide-changing resistor device or controllable silicon are constituted.The structure of impeller is close in the structure of impeller (11) and the centrifugal water pump, different blade (A) be cast as one on, lower plate is an inverted cone-shaped structure, so that increase the cast of water outlet.In addition, the axial length of small sleeve (B) is longer than the axial length of big sleeve (C), and be equipped with at (B) sleeve place respectively little wear ring (8) and (C) the sleeve position big wear ring (6) is housed, to increase the service life.Retaining chamber (12) is by big in the oil sealing containing sealing impeller (11) wherein, the member of small sleeve, its top is processed with stepped hole (D) and groove (E), be used to assemble big oil sealing (10), pad (5), circlip (4) is processed with stepped hole (F) in the bottom, be used to assemble little oil sealing (9), be processed with flanged (FLGD) inlet opening (G) on the right side, in order to come water pipe to be connected, on the lower flange of retaining chamber, be processed with the hole that aperture and quantity and electromotor (13) match, positioning step (H) that promptly can electromotor (B) by bolt (3) is a benchmark, with retaining chamber (12), shell (1), terminal pad (2) is assembled together.And by bolt (7) and key impeller (11) is connected make it constitute one on the axle of electromotor (13) can be through rotation to the even electronic farm implements of water spray of peripheral plant.Backstay (14) and terminal pad (2) are riveted together, and it will be used for penetrating soil, guarantee the stability of centrifugal sprinkler.

The use of centrifugal sprinkler is fairly simple, only (G) locates to install a flexible pipe to need in the inlet opening, be connected with running water pipe or pumping line, starting motor, just can begin pouring, and, wait the rotating speed of controlling electromotor by handling frequency converter or slide-changing resistor device and controllable silicon according to the degree of drought and the presence states of soil, can realize the irrigation of guaranteeing the quality, water-saving irrigation.

Claims
