Abstract
The utility model relates to a tunneler shovel plate surface protection device which comprises a star wheel, wear-resisting steel plates, fixed bolts and a shovel plate body, wherein fixed screw holes are arranged on the shovel plate body, corresponding fixed holes are arranged on the upper surfaces of the wear-resisting steel plates which are fixed on the shovel plate body by the fixed bolts. The tunneler shovel plate surface protection device has simple structure, more wear-resisting steel plates, convenient replacement and transportation, and good wear-resisting property of steel plates, prolongs the service life and the maintenance cycle, reduces the labor intensity of underground personnel and the production cost, and improves the production efficiency.
Description
Technical field: the utility model relates to a kind of development machine shovel board surface protection device.
Background technology: at present, in the headwork of hard rock mole, when the scar that cut gets off is shipped to first transporter in shovel board, because star-wheel drives the material rotation, and then the surface that causes material wearing and tearing shovel board, influence application life of shovel board, change and keep in repair the labour intensity that shovel board has increased the personnel in the pit, improve cost of production, reduced production efficiency.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of development machine shovel board surface protection device is provided, it has mainly solved material wearing and tearing shovel board surface, influences the application life of shovel board, changes and problems such as maintenance shovel board increase labour intensity and cost of production.The purpose of this utility model is achieved in that development machine shovel board surface protection device is made of: star-wheel, wear-resisting steel plate, set bolt, shovel board body.Star-wheel is contained on the shovel board body, has several fixing threaded holes on the shovel board body, and wear-resisting steel plate has polylith, has several corresponding fixing holes on it, and wear-resisting steel plate is fixed on the shovel board body by set bolt.This product structure is simple, and the wear-resisting steel plate polylith is changed convenient transportation, and steel plate is anti-wear good, has prolonged application life and maintenance cycle, has reduced personnel in the pit's labour intensity and cost of production, has improved production efficiency.
