Abstract

The invention discloses a development machine capable of spraying inwards, which comprises a cutting device, a development machine body and an inward spraying device. A nozzle of the inward spraying device is arranged on the cutting device and comprises an inner pipe, an outer sheath and a fixing ring. The inner pipe is provided a shutter formed by arranging a plurality of fan-shaped valves inside. The circular arc end of each fan-shaped valve is hinged with the inner wall of the inner pipe; the fixing ring is fixed in the inner pipe and positioned on the inner side of the shutter. The outer sheath can be sleeved on the inner pipe in a sliding way; the front end cover of the outer sheath is provided with holes; and the outer sheathe is connected with the inner pipe through a spring. When the spring is in a free state, the fan-shaped valves are crushed into a smooth circular shutter by the front end cover of the outer sheath and the fixing ring. The nozzle of the inner spraying device opens only when spraying. Dust cannot enter the nozzle because of the water pressure generated during spraying; and the nozzle is in a closed state when not spraying, and the dust cannot enter the nozzle either. The development machine can effectively avoid blockage.

Description

A kind of development machine of inner-atomizing

Technical field

The present invention relates to the development machine of a kind of development machine, particularly a kind of inner-atomizing.

Background technology

Development machine is understood frictional heat and is produced spark in the cut operation, have a kind of development machine of inner-atomizing at present, and this kind development machine is provided with inner sprayer unit, when the cut operation, by internal spraying, can reduce the temperature of cutting means, effectively suppress fricative spark in the cut operation.But the dust that cut produces stops up the nozzle of inner sprayer unit easily, and making spraying that water can not be unobstructed has influenced the cooling to cutting means from nozzle.

Summary of the invention

The technical problem to be solved in the present invention is: a kind of development machine of inner-atomizing is provided, makes the nozzle of its atomization mechanism be difficult for stopping up.

In order to solve the problems of the technologies described above, the present invention includes cutting means, development machine main body and inner sprayer unit, the nozzle of inner sprayer unit is arranged on the cutting means, described nozzle comprises interior pipe, overcoat and retainer ring, be provided with the flashboard that is arranged in by a plurality of fan-shaped flap valves in the interior pipe, the arc end of each fan-shaped flap valve and the inwall of interior pipe are hinged, retainer ring is fixed in the interior pipe and is positioned at the inboard of flashboard, overcoat slidably overlaps on inner pipe, porose on the drive end bearing bracket of overcoat, be connected with spring between overcoat and interior pipe, when spring was in free state, overcoat drive end bearing bracket and retainer ring were squeezed into a smooth circular flashboard with a plurality of fan-shaped flap valves.

Bad in order to prevent that spring from being drawn, and make the maximum open shape of nozzle and size make it have preferable atomizing effect, be provided with stopping means between pipe and the overcoat in described, internally the radius of the circular hole on the drive end bearing bracket of the maximum coasting distance of pipe, overcoat and described flashboard radius three's ratio are 11: 13: 17 mutually for the concentric circular hole of Kong Weiyu drive end bearing bracket on the drive end bearing bracket of described overcoat, overcoat.

In order to make nozzle have best atomizing effect, be provided with sealing ring between pipe and the overcoat in described, the concentric big hole of Kong Weiyu drive end bearing bracket on the drive end bearing bracket of described overcoat and be distributed in small sircle hole around this big hole, be distributed with 16 small sircle holes around the big hole, the big hole radius is 11 times of small sircle hole, and the sidewall of overcoat front end is provided with and the circular hole of aforementioned small sircle hole with the footpath.Having put a plurality of positions and direction outward can spray water, and the atomizing area is big, effective.

The invention has the beneficial effects as follows: the shower nozzle of inner sprayer unit of the present invention is only just opened when spraying, and during spraying, because the pressure effect of water, dust can't enter nozzle, and when not spraying, nozzle is in closed condition, and dust also can't enter nozzle.Highly effectively avoided obstruction.
