Abstract
The invention discloses a pickholder system for mining machinery. The pickholder system comprises a bit, a bit base, a nozzle and a nozzle base, wherein the big base is provided with the bit, the nozzle base is provided with the nozzle, a spray orifice is formed on the nozzle, the nozzle base is located below the bit base, the bit base and the nozzle base are independent to each other and deflected relative to each other, so that the spray orifice can be regulated to a special direction before the nozzle base is fixedly located; the nozzle base is fixedly connected with the bit base, a bottom water channel of the bit base is communicated with a bottom water channel of the nozzle base, and the water is sprayed from the spray orifice. The pickholder system for the mining machinery provided by the invention has the advantages of simple structure, excellent processing technique and accurate spraying.
Description
Technical field
The present invention relates to a kind of mining machinery, relate in particular to the pick box system that a kind of mining machinery is used.
Background technology
At present both at home and abroad the spray structure on the mining machinery cutterhead mostly is before split type, one spray formula after spray formula or one.split typely be welded on separately on the body of the cutting head or blade for pick box and nozzle carrier, nozzle carrier is welded on the internal spraying weep hole counterbore place of the body of the cutting head or blade, the internal spraying press water enters nozzle carrier by this internal spraying weep hole and sprays from nozzle, this structure is because nozzle carrier is arranged on the body of the cutting head or blade weep hole counterbore place, in case counterbore completion of processing, spray direction is namely fixed, yet toothholder often as required deflection to reach good cutting effect, therefore, split-type structural easily causes spray direction skew pick, and nozzle location is lower, easily blocked.The nozzle of spray formula is arranged on the position, upper back of pick box body more before one, and this place is processed with the inclined hole that nozzle is installed, its orientation of its axis pick, and this inclined hole communicates with toothholder bottom tank, and tank communicates with the body of the cutting head or blade internal spraying weep hole bottom toothholder; Nozzle sprays to the pick on this toothholder, and the spraying precision is good, but because nozzle is positioned at the pick tangential direction and towards direction of rotation, the material that cutterhead is cut off easily enters nozzle, with spray nozzle clogging substantially.After one, the spray formula is the rear portion that nozzle is arranged on this toothholder, spray to next pick, the not spraying of the pick on this toothholder, due to when design often with toothholder deflection to reach good cutting effect, cause two toothholders be not just before just after, relative deflection is often arranged, thus the reduction of spray effect easily caused, and the welding positioning accuracy of front and back two toothholders also affects the accuracy that spraying arrives crown.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the weak point of above-mentioned three kinds of forms, provide that a kind of structure is simple, processing technology better, the Pickholder system for mining machinery accurately of spraying.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of Pickholder system for mining machinery, comprise pick, toothholder, nozzle and nozzle carrier, pick is installed on toothholder, nozzle is installed on nozzle carrier, spray orifice is arranged on nozzle, nozzle carrier is in the back lower place of toothholder, toothholder and nozzle carrier are separate, and both deflection relatively, so that make nozzle carrier in position before, can make spray orifice towards a certain specific direction, be fixedly connected with between nozzle carrier and toothholder, toothholder bottom tank tank bottom nozzle carrier communicates, and water sprays by spray orifice.When separate toothholder is fixedly connected with nozzle carrier, can be first connect toothholder and nozzle carrier and the relative position of nozzle carrier and toothholder is carried out Primary Location by a hold-down screw, by regulating the position of front the nozzle carrier after toothholder, make this nozzle carrier toothholder deflection relative to it certain angle, and make spray orifice on nozzle towards a certain specific direction, as aim at the pick crown of rear adjacent, further toothholder and nozzle carrier are located by connecting by welding at last.So, the device that is fixedly connected with between nozzle carrier and toothholder can be comprised weld seam between a screw and nozzle carrier and toothholder, this screw is used for nozzle carrier and toothholder Primary Location, so as to make nozzle carrier in position before, make spray orifice towards a certain specific direction.On pick box, the tooth cover can also be installed, the pick afterbody can also have back-up ring or snap ring, can be used for pick is carried out axial limiting.
Superiority of the present invention is: because nozzle and pick are arranged on respectively on the nozzle carrier-toothholder with relative annexation, the position relationship between the pick of nozzle and rear adjacent easily is guaranteed, and has improved the accuracy of spraying point; Be in the back lower place of toothholder due to nozzle, be conducive to protect nozzle, make nozzle be difficult for being smashed, and spray direction has been avoided the tangential direction of pick point movement locus; In addition, because nozzle carrier is adjustable with respect to the toothholder position, especially for coal-winning machine, for arriving good cutting effect, toothholder is deflection certain angle relatively often, and this mode has solved the shortcoming of spray formula after the one.
Description of drawings
Below in conjunction with accompanying drawing, instantiation of the present invention is described in detail, wherein:
Fig. 1 is the sectional view of pick box of the present invention system;
Fig. 2 is pick box of the present invention system bottom schematic view.
The specific embodiment
The split type pick box of the rear spray system that mining machinery is as shown in Figure 1 and Figure 2 used, pick 1, tooth cover 2 are arranged in toothholder 3 successively, and back-up ring 4 is contained in pick 1 afterbody; Toothholder 3 is connected by revolution screw 6 with nozzle carrier 5, and both can turn certain angle relatively; Nozzle 7 is arranged in nozzle carrier 5; Toothholder tank 8 communicates with nozzle carrier tank 9, and nozzle installing hole 10 communicates with nozzle carrier tank 9.
During installation, toothholder 3 before and after first spot welding by drawing is fixing, the position of the nozzle carrier 5 before then regulating after a toothholder 3, make its this toothholder 3 deflection certain angles relatively, so that the spray orifice on nozzle is aimed at the crown of the pick 1 on back toothholder 3, further toothholder and nozzle carrier are located by connecting by welding at last; During work, cooling pressure water arrives nozzle carrier tanks 9 by toothholder tank 8, then sprays to pick 1 on back toothholder 3 through nozzle installing hole 10 from the spray orifice of nozzle, to reach effective internal spraying effect.
