Abstract
The utility model relates to coal mining machinery, in particular to a pickholder component used for a development machine. The pickholder component is installed in the cutting mechanism of the coal mine machinery in the work process of the coal mining machinery, used for the cutting head for cutting the coal and rock of the mining machinery, and welded on the cutting head. The pickholder component comprises a pick, a toothed sleeve and a pickholder body, wherein the pickholder body is installed with a nozzle and the toothed sleeve; and a pick handle is installed in the toothed sleeve. For the pickholder component, the form of the pickholder component generally welded on the cutting head of the development machine is complemented, and the pickholder component with the structure can better solve the failure problem of the pickholder and pick in the working process due to overhigh temperature, and the problem of the pickholder body attrition caused by the pick in the working process.
Description
Technical field
The utility model relates to the colliery mining machinery, specifically be a kind of development machine pick box assembly, it is in the mining machinery course of work of colliery, is installed in the coal mine machinery cutting mechanism, the cutterhead that is used for mining machinery cut coal and rock, the pick box assembly that on cutterhead, welds.
Background technology
At present, the colliery extractive equipment is mainly development machine.In the process that reality is used, the pick box on the cutting head of roadheader generally weares and teares more serious.In addition, in cutterhead cut rock, tend to the application life of reducing pick and pick box because produce a large amount of heats.Because cutterhead and pick box mostly weld together now.So pick box influences the drivage efficiency of whole development machine in case inefficacy is repaired or changed and will bother very much in the down-hole.Therefore, the pick box assembly with regard to need a kind ofly being not easy relatively to wear and tear or be convenient to change.
The utility model content
The purpose of this utility model is to provide a kind of development machine pick box assembly, adopt structure of the present utility model can well solve the problem that pick box and pick lost efficacy owing to temperature is too high at work simultaneously, and pick is in the course of the work to pick box body wear problem.
The technical solution of the utility model is:
A kind of development machine pick box assembly, this pick box assembly is provided with pick, tooth cover, pick box body, and nozzle and tooth cover are installed on the pick box body, the tooth handle of pick setting in the tooth cover.
Described development machine pick box assembly, tooth cover are installed in the stepped bore on the pick box body, and the upper surface of pick box body and stepped bore one section cooperates with the tooth cover; The shank of pick is plugged in the tooth cover, and cooperates with pick with another section of tooth cover inner arm and stepped bore.
Described development machine pick box assembly, an end of pick is provided with back-up ring, is connected in the lower surface of pick box body, cooperates the shank of common clamping pick with the lower surface of pick box body.
Described development machine pick box assembly, the bottom opening of pick box body, the hole is positioned at the next door of pick, and nozzle is installed in the hole.
Described development machine pick box assembly has the water channel that communicates with described hole in the pick box body.
The beneficial effects of the utility model are:
1, the utility model has the pick box assembly of tooth cover and internal spraying nozzle, comprises pick box body, tooth cover, nozzle, and the pick box body can dispel the heat better, and wearing and tearing are occurred between pick and the tooth cover.This pick box assembly replenishes the pick box kit form that generally welds on the cutting head of roadheader.
2, also upwards increase water channel in pick box body bottom opening, when internal spraying is opened, water will enter the water channel of pick box body interior from pick box body bottom, from the top ejection of pick box body, thereby the pick box body be cooled off.
3, pick box body of the present utility model is designed to stepped bore, and one section cooperates with tooth cover, and one section cooperates with pick, and pick box body upper surface is overlapped with tooth and cooperated, and the lower surface cooperates common clamping pick shank with back-up ring, pick is fixed in the pick box body.
4, the utility model pick can rotate in the tooth cover, pick weares and teares with the tooth cover in the cut process, when wearing and tearing cause the excesssive gap of pick and tooth cover, directly changes the tooth cover and gets final product, thereby reduced the wearing and tearing of pick box body, improved the life-span of pick box body.
5, the utility model tooth cover adopts conical surface centering with the pick box body, has reduced error; The tooth cover also leaves a fixed gap with the end face of pick box body, makes easier taking-up when changing the tooth cover.
