5, lower device: lower casing, inlet point, tailing axle assembling, tightening device (optional dress speed measuring device).
The characteristics of NSE plate chain type gig:
1, traffic capacity is big: this series gig is that gig, the lifting capacity of close cross sectional dimensions operational throughput maximum in the domestic gig is 100～1000m3/h;
2, expanded reach is wide: this class gig requires few to kind, the characteristic of material; Not only general granular material can be promoted, and the bigger material of chiseling property of mill can be promoted; Require temperature of charge≤200 ℃;
3, driving power is little: adopt inflow formula feeding, induction type discharging, the intensive layout of high-capacity hopper; When material promotes, almost do not have feed back and dig the material phenomenon, so reactive volt-amperes is few, save power about 30% than loop chain gig;
4, long service life: the feeding of gig is taked the inflow formula, need not to dig material, rare extruding and collision phenomenon between the material with bucket; This machine has slightly when when design guarantees material in feeding, gig discharging and is scattered, and has reduced mechanical wear, adopts plate chain type high-strength abrasion-proof conveyer chain, has prolonged the service life of conveyer chain and hopper greatly, the normal use down, and conveyer chain service life was above 3 years;
5, hoisting depth height: this gig operates steadily, and adopts plate chain type high-strength abrasion-proof conveyer chain, therefore can reach higher hoisting depth, under specified operational throughput, and hoisting depth≤50m
6, good airproof performance, low in the pollution of the environment;
7, serviceability is good: advanced principle of design and job operation, guaranteed the complete machine reliability of operation, and failure free time was above 20,000 hours;
8, operation, easy to maintenance, few easy workout part;
9, the rigidity of structure is good, the precision height: casing is after the die mould welding, and good rigidity and outward appearance are beautiful;
10, integrated cost is low: because energy efficient and maintenance are few, use cost is low.
Contrast accompanying drawing below, by description to embodiment, to effect and principle of work, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
