Abstract
The utility model relates to a fore spraying integrated internal spraying device for roadheader cutting head, which includes a cutting head body, a cutting pick, a pick housing and a nozzle, the surface of the cutting head body is welded with pick housings according to certain rules, the inner of the pick housing has a pathway leading to the cutting head body internal water cavity, the pick housing is provided with the cutting pick and the nozzle, the nozzle center line of each pick housing is directed to the cutting pick tip installed on the pick housing, the position relation between the two can be easily ensured to improve the accuracy of the spraying point; furthermore, because the nozzle is inner-placed under the cutting pick, the tangential direction of the motion track of the cutting pick tip is avoided through spraying, the spraying distance is shortened, the splash and interference of cut material is decreased and the spraying effect is strengthened.
Description
Technical field
The utility model sprays integral type internal spraying structure before relating to a kind of cutting head of roadheader, belongs to mining machinery.
Background technology
Present domestic development machine internal spraying structure mostly be split type or one after the spray formula, split typely be welded in and be installed on the cutting head of roadheader body respectively for toothholder and nozzle, toothholder does not communicate with the internal spraying press water, and press water directly sprays from nozzle by the water channel in the body of the cutting head, and this structure is installed on the body of the cutting head owing to nozzle, processing taper type the body of the cutting head manufacturability is relatively poor, the spraying point location is inaccurate, and nozzle is lower, and is blocked easily, and the spraying distance, cooling and lubricant effect are relatively poor; The spray formula is the rear portion that nozzle is installed in toothholder after the one, spray to next pick, the not spraying of the pick on this toothholder, also there is the spraying distance in this structure, enter material easily in the spraying stroke, cut off spray, make spray nozzle clogging easily, because the nozzle on the last toothholder sprays to the pick on one toothholder of back, the welding location precision spray water of two toothholders arrives the accuracy of pick point simultaneously.
Summary of the invention
The purpose of this utility model is to overcome the weak point of above-mentioned two kinds of forms, and a kind of simple in structure, the preceding accurately spray integral type of spraying development machine inner sprayer unit is provided.
Embodiment of the present utility model is: a kind of cutting head of roadheader inner sprayer unit, comprise the body of the cutting head, pick, toothholder, nozzle, the toothholder of some is welded on the body of the cutting head surface regularly, pick and nozzle are installed on the toothholder, water route in nozzle and the toothholder communicates, the water route communicates with water channel in the body of the cutting head again in the toothholder, and the nozzle alignment on each toothholder is installed in the pick crown on the same toothholder.
On the such scheme basis, the corresponding pick crown of described nozzle center linear distance is the 3-8 millimeter.
Superiority of the present utility model is: because nozzle and pick are installed on the same toothholder, position relation between the two guarantees easily, has improved the accuracy of spraying point; Because nozzle is built under the pick, and spray direction has been avoided the tangential direction of pick point movement locus, shorten the distance of spraying in addition, reduced the interference of splashing of cut material, strengthened spray effect.
Description of drawings
Fig. 1 is the utility model cutting head of roadheader nozzle scheme of installation.
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: shown in Fig. 1 the utility model cutting head of roadheader nozzle scheme of installation, the toothholder 3 that has welded some is arranged on the body of the cutting head 1 surface regularly, nozzle 4 and pick 5 are installed on the toothholder 3, the center line of nozzle 4 is aimed at the crown of pick 5, shown in the A-A sectional view that Fig. 2 is Fig. 1, promptly the X value is the 3-8 millimeter among the figure; Water route 6 in nozzle 4 and the toothholder 3 communicates, and water route 6 communicates with water channel 7 in the body of the cutting head 1 again in the toothholder.
During work, cooling pressure water B point in the body of the cutting head 1 sets out and one the tunnel arrives nozzle 4 places, and nozzle is directly towards crown 5 certain limit internal sprayings, and the spray stroke is short, and impact force is big, reaches effective internal spraying effect.
Claims (2)
1. cutting head of roadheader inner sprayer unit, comprise the body of the cutting head, pick, toothholder, nozzle, the toothholder of some is welded on the body of the cutting head surface regularly, pick and nozzle are installed on the toothholder, water route in nozzle and the toothholder communicates, the water route communicates with water channel in the body of the cutting head again in the toothholder, and it is characterized in that: the nozzle alignment on each toothholder is installed in the pick crown on the same toothholder.
2. cutting head of roadheader inner sprayer unit according to claim 1 is characterized in that: the corresponding pick crown of nozzle center's linear distance is the 3-8 millimeter.
