Abstract

The utility model relates to a sprinkling machine with a coiled pipe, which can carry out sprinkling irrigation on crops and lawns in a moving mode. The present sprinkling machine with the coiled pipe needs two sets of dynamic-force pipe pressing devices, and has complicated structure; the crops can be damaged by that a water delivery hose is wound to wobble to and fro. The utility model is formed by that a machine frame of the sprinkling machine (18) is hinged with a tractor in a single-point mode by a telescopic shaft (25); a stand (6) of a water pump (4) can move on a fixed slide plate (43) via a rotating screw rod (39); a sleeve pipe of the pipe pressing device (19) is hinged with a mandrel (29) on amain beam (30); one end of a guider is inserteed into a sleeve (21); the other end of the guider is fixedly connected with two plugs (48) and two pin shafts (46) which are hinged with two sliding wheels (47). Adopting the structure, the utility model enhances the applicable property of the sprinkling machine, greatly reducing manufacturing cost.

Description

The hose reel type irrigation sprinkler

The present invention relates to a kind of hose reel type irrigation sprinkler.

Existing hose reel type irrigation sprinkler is made up of frame, capstan winch, delivery hose, racker, guider, pressure tube device, water pump, shower nozzle car and hydroturbine transmission system.During work, irrigation sprinkler is placed an end to be irrigated the fields, dragging the straight delivery hose of shower nozzle car exhibition irrigates the fields in waiting, put the shower nozzle car in opposite side to be irrigated the fields, engine drives water pump will not had setting-out and become pressure water and offer hydroturbine and shower nozzle through delivery hose, hydroturbine is high speed rotating under the effect of water under high pressure, driving capstan winch after the transmission system speed change rotates, when capstan winch rotates, twine delivery hose and drive shower nozzle car straight line return, be installed in shower nozzle on the shower nozzle car under the effect of water under high pressure around axis swing and water spray, to realize moving sprinkling irrigation (" mechanization sprinkling irrigation ", FAO (Food and Agriculture Organization of the United Nation), Rome, 1982).But existing type needs two cover power establish machine, is respectively applied for irrigation sprinkler transportation and work, and pressure tube device and guide structure complexity, size big, need use special material.When taking into account irrigation sprinkler transportation and work with an engine, for guaranteeing that unit has good transport performance, draw bar should have enough length, the unit longitudinal size is increased, and the chain drive wheelbase of tractor driving wheel and irrigation sprinkler decelerator can not satisfy the designing requirement of 30～50 zip lengths, falls chain easily and bumps the chain phenomenon; And, separate the clutch mechanism more complicated of water pump power because water pump directly passes through belt drives by the higher tractor clutch belt pulley of rotating speed.

The purpose of this invention is to provide a kind of with small tractor during as irrigation sprinkler transportation and work simple in structure, the cheap small-sized line of power coil the tubular type irrigation sprinkler.

Task of the present invention is finished as follows: irrigation sprinkler frame [18] is hinged with telescopic shaft [25] and tractor single-point, the moving slide plate [37] that water pump [4] is installed can pass through rotational lead screw [39], and upward front and back are mobile deciding slide plate [43], the sleeve pipe [32] of pressure tube device [19] is hinged with the axle [29] on the girder [30] that is fixed on the frame [18], one end of guide bar [45] can freely insert in the cover [21] that connects firmly on frame [18], the other end connects firmly an angle bar [49], the below connects firmly 2 plugs [48], and it is the movable pulley of circular arc [47] that there are two buses the top.During work, the tractor-drawn irrigation sprinkler is in waiting to irritate the ground rand, fixedly retreating tractor behind the irrigation sprinkler makes telescopic shaft [25] move to extreme position behind sleeve pipe [26], move water pump [4] behind the rotational lead screw [39] to V belt [2] tensioning, the tractor rear axle of jack-uping, make the liftoff 20～30mm of driving wheel, regulating backguy double helix [36] tensioning backguy is rigidly connected tractor and irrigation sprinkler, one end of rod-type guider [45] is inserted in the cover [21], the other end inserts in the soil, and delivery hose [12] packed between the pulley [47], drag shower nozzle car [17] in waiting to irritate the ground opposite side, when dragging shower nozzle car [17], the delivery hose [12] that is wrapped on the capstan winch [11] launches from capstan winch [11] under the effect of pressure tube device [19] gradually, operated clutch shifting fork mechanism [24] makes the clutch combination, after starting tractor, water pump [4] provides press water through V belt [2] driving work to delivery hose by the tractor clutch belt pulley, the rotation of off hind wheel is slowly rotated through secondary chain drive and reducer of turbodrill deceleration rear drive capstan winch [11], and rollback delivery hose [12], delivery hose [12] is under the guiding of two movable pulleys [47] on the guider, delivery hose [12] and shower nozzle car [17] straight line are retreated, shower nozzle [16] ejection of press water on the shower nozzle car, simultaneously shower nozzle [16] reciprocally swinging in the certain limit in the horizontal direction under the effect of press water can be finished a sprinkling irrigation near the rectangular area.Mobile unit is treated the territory, irrigated area and repeats said process that the sprinkling irrigation that can finish is en bloc irrigated in another.

Advantage of the present invention is, draw bar has adopted telescopic shaft, has both guaranteed the traction requirement of unit, can reduce again right driving wheel to the chain drive wheelbase of decelerator, guarantee two sprocket wheels on same plane, avoided the chain phenomenon to take place; By rotational lead screw the water pump stand is moved forward and backward realize the tensioning of V belt and when transporting water pump power separate, saved baroque arrangement of clutch, reduced cost; Pressure tube device is simple in structure, low cost of manufacture; Guider guiding delivery hose straight line reclaims, and has prevented the reciprocating and phenomenon of damage crop when delivery hose twines on capstan winch.Adopt example structure as detailed below, can improve the service behaviour of pipe crimping formula irrigation sprinkler and reduce manufacturing cost.
