Abstract
The utility model belongs to a sprayer unit and particularly discloses a reinforced preposed external sprayer unit for an entry-driving machine. The external sprayer unit comprises a sprayer block and a conduit communicated with the sprayer block and is characterized in that the sprayer block is ringwise arranged on a barrel body of an external protective barrel at the flexible part of the entry-driving machine, nozzles are uniformly distributed on the sprayer block, and the angles of the nozzles correspond to tooth points of a cutting gun head. The external sprayer unit and the barrel body of the external protective barrel are integrally designed, the structure is compact, the collision loss is avoided, the dust fall is realized, cutting teeth can be cooled simultaneously, the disadvantage of the inner sprayer is made up, and the external sprayer unit is suitable for wide popularization and application.
Description
(1) technical field
The utility model belongs to atomization mechanism, the reinforced preposition external spraying device of particularly a kind of development machine.
(2) background technology
In domestic Internal Spraying System of Driving Machinrey now not very under the mature technique prerequisite, the design of development machine external spraying plays a key effect, the development machine external spraying mainly contains the spraying piece of design in development machine working arm top and both sides at present, top spraying piece generally is designed to bar shaped or circular arc, be fixed on tunneling machine cutting reduction box top, two side spray pieces mostly are bar shaped and vertically are arranged in tunneling machine cutting reduction box both sides, and its shortcoming is: 1. spraying piece in top breaks in cutting process easily; 2. nozzle distance cut big gun head possesses Telescopic apart from too far away as development machine, and the spraying piece can not more strengthen the distance of nozzle distance big gun head with the same moved further of pars contractilis, has reduced dust-laying effect; 3. can only realize three depositing dusts of top and both sides, the dust fall of development machine bottom can't be eliminated.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, a kind of compact conformation is provided, effectively avoided the reinforced preposition external spraying device of development machine of clashing and breaking.
The utility model is achieved by the following technical solution:
The reinforced preposition external spraying device of a kind of development machine; the aqueduct that comprises spraying piece and connection spraying piece; it is characterized in that: described spraying piece is arranged on the cylindrical shell of outer protection tube of development machine pars contractilis ringwise; nozzle is evenly distributed on the spraying piece, the crown of corresponding its place ahead cutting big gun head of the angle of nozzle.
Spraying piece design of the present utility model is on the cylindrical shell of the outer protection tube of development machine pars contractilis, and structure is for being circular layout, and portion forms water annulus within it, and nozzle is evenly distributed on the water annulus; The angle of nozzle is around the crown of cutting big gun head, can also cool off pick when realizing depositing dust, has remedied the shortcoming of internal spraying deficiency.
More excellent scheme of the present utility model is:
Described aqueduct is installed in the metal catheter in the cylindrical shell, by metal catheter water annulus is supplied water, and is communicated to each uniform nozzle.
The utility model and outer protection tube barrel designs are one, and compact conformation has been avoided clashing and breaking, can also cool off pick when realizing depositing dust, has remedied the shortcoming of internal spraying deficiency, is suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is a main TV structure schematic diagram of the present utility model.
Among the figure, 1 spraying piece, 2 cylindrical shells, 3 nozzles, 4 aqueducts.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises spraying piece 1 and is communicated with the aqueduct 4 of spraying piece, described spraying piece 1 is arranged on the cylindrical shell 2 of outer protection tube of development machine pars contractilis ringwise, nozzle 3 is evenly distributed on the spraying piece 1, the crown of corresponding its place ahead cutting big gun head of the angle of nozzle 3; Described aqueduct 4 is installed in the metal catheter in the cylindrical shell 2.
During use, by supplying water in 4 pairs of sprayings of metal catheter piece 1, from being distributed on ejection in the nozzle 3 on the spraying piece 1, its spray angle is around the crown of cutting big gun head, when realizing depositing dust pick is cooled off with water.
Claims (2)
1. reinforced preposition external spraying device of development machine; the aqueduct (4) that comprises spraying piece (1) and connection spraying piece; it is characterized in that: described spraying piece (1) is arranged on the cylindrical shell (2) of outer protection tube of development machine pars contractilis ringwise; nozzle (3) is evenly distributed on the spraying piece (1), the crown of corresponding its place ahead cutting big gun head of the angle of nozzle (3).
2. the reinforced preposition external spraying device of development machine according to claim 1 is characterized in that: described aqueduct (4) is installed in the metal catheter in the cylindrical shell (2).
