Description
Affiliated technical field
The utility model relates to the vitals of coal mine roadway development machine, is specially the development machine shovel board part device of a kind of dovetail groove form (semi-open-type), is applicable to the collection and the transportation of development machine material.
Background technology
At present, the shovel board part device rewinding of development machine relies on star-wheel-drive device or crab claw device fully, star-wheel or crab claw are pushed to the material of collecting in the middle chute of shovel board, and the scraper chain device is transported to follow-up conveying mechanism along chute base plate moving handle material in chute.The material collection of this mode causes the chain jamming phenomenon of scraper chain easily.In addition, rely on star-wheel-drive device or crab claw device fully, load is bigger, is easy to produce early stage damage.
The utility model content
In order to have solved the chain jamming problem of scraper chain, reduce star-wheel-drive device or crab claw device rewinding load, reduce fault, the utility model provides a kind of development machine shovel board part device, the scraper chain conveying arrangement is exposed, avoid the chain jamming phenomenon, can carry out rewinding and transport simultaneously, reduce star-wheel-drive device or the rewinding of crab claw device load.
The technical scheme that the utility model adopted is:
A kind of development machine shovel board part device, this device is provided with shovel board body, scraper chain conveying arrangement, and the middle part of shovel board body is provided with the scraper chain conveying arrangement, and the spear middle part of shovel board body is trapezoid groove structure, and the scraper chain conveying arrangement is corresponding with dovetail groove.
Described development machine shovel board part device also is provided with left star-wheel-drive device and right star-wheel-drive device, and left star-wheel-drive device and right star-wheel-drive device symmetry are installed on the shovel board body.
Described development machine shovel board part device also is provided with left crab claw device and right crab claw device, and left crab claw device and right crab claw device symmetry are installed on the shovel board body.
Described development machine shovel board part device, the scraper chain conveying arrangement is in transmission connection by main driving wheel device and driven pulley device respectively.
Described development machine shovel board part device, driven pulley device installation site is near spear.
Described development machine shovel board part device, the peak of scraper chain conveying arrangement is higher than the dovetail groove bottom surface.
Described development machine shovel board part device, the peak of scraper chain conveying arrangement is higher than dovetail groove bottom surface 50～150mm.
Described development machine shovel board part device, the scraper chain conveying arrangement is lower than the shovel board plane.
Described development machine shovel board part device, the scraper chain conveying arrangement is lower than shovel board plane 10～30mm.
The beneficial effects of the utility model are:
1, the utility model has changed the function that existing shovel board part device relies on star-wheel device or crab claw device collection material merely, be designed to the dovetail groove form at shovel board body spear middle part, the driven pulley device is as far as possible near spear, make the scraper chain conveying arrangement exceed dovetail groove bottom surface (being that the scraper chain conveying arrangement exposes), material can shovel or directly drop on the scraper chain conveying arrangement and transport by the dovetail groove at shovel board middle part.The utility model exposes the scraper chain conveying arrangement, can avoid the chain jamming phenomenon to take place, and have the function of collection material, and the scraper chain conveying arrangement can be collected the material that drops on the spear middle part and transport; Thereby, promote shovel board portion rewinding ability, reduce the rewinding load of shovel board star-wheel device or crab claw device.
2, the spear of the utility model shovel board body middle part is lower than shovel board plane, makes the spear middle part of shovel board body be the dovetail groove form, is easy to collection material.
