专利汇可以提供Ramp plate and loader for mineral conveyors专利检索，专利查询，专利分析的服务。并且The invention discloses space-clearing means for use particularly in long-wall mining, comprising a train of ploughs mounted for movement along a guide ramp on the face side of a conveyor. The ploughs are linked by means transmitting both tension and compression and means are provided whereby a cutting machine can engage any selected plough of the train to push or pull the ploughs in any combination, in either direction of the machine.，下面是Ramp plate and loader for mineral conveyors专利的具体信息内容。
1. Long-wall mining equipment comprising a face conveyor, a guide ramp extending facewards from the face side of said conveyor, a train of ploughs mounted for movement along said guide ramp, linking means between every pair of adjacent ploughs, said linking means for use both in tension and in compression for transmitting movement from one of said ploughs to an adjacent one of said ploughs, a cutting machine movable along the face, and means on said cutting machine and on said train for transmitting the movement of said cutting machine to said ploughs so that said machine may both push and pull said ploughs in both directions of movement of said machine.
2. Long-wall mining equipment as claim in claim 1 wherein each individual plough in said train has means engageable by said cutting machine for transmitting movement of said cutting machine in either direction to said train of ploughs.
3. Long-wall mining equipment as claimed in claim 2 wherein said engageable means on each said plough is fixed, and other engageable means is provided on said cutting machine and is movable so that it may engage and disengage said engageable means on any said plough.
4. Long-wall mining equipment as claimed in claim 3 including control means for said other engageable means on said cutting machine, said control means being operable from the goaf side of said cutting machine.
5. Long-wall mining equipment as claimed in claim 1 wherein said linking means comprises a continuous wire rope anchored at its ends respectively to the two ends of said train, and at least one rigid sleeve surrounding the rope and positioned between adjacent ploughs.
6. Long-wall mining equipment as claimed in claim 5 wherein one of said sleeves and one of said ploughs are spaced apart by a spacing collar having a central section and end sections tapering downwardly from said central section to fit in bores in said sleeve and said plough respectively.
7. Long-wall mining equipment as claimed in claim 5 wherein two adjacent sleeves are spaced apart by a spacing collar having a central section and end sections tapering downwardly from said central section to fit in bores in said sleeves.
8. Long-wall mining equipment as claimed in claim 6 in which each spacing collar has a central axial bore of diameter sufficient to receive and hold the wire rope against transverse movement within the bore.
9. Long-wall mining equipment as claimed in claim 8 in which each spacing collar has a central axial bore of diameter sufficient to receive and hold the wire rope against transverse movement within the bore.
10. Long-wall mining equipment as claimed in claim 5 wherein each end of said wire rope is anchored to a plough nose adjacent to the respective end plough and extending away from said train.
11. Long-wall mining equipment as claimed in claim 10 wherein said toe plate has a downwardly chamfered end.
12. Long-wall mining equipment according to claim 5 in which the lengths of all said ploughs and all said sleeves are equal.
13. Long-wall mining equipment as claimed in claim 1 wherein said guide ramp has a foot section, and a toe plate is provided at the face side of sAid foot section extending beyond the face side of said ploughs.
14. Long-wall mining equipment as claimed in claim 1 wherein each said plough has a single longitudinal guide member fitting into a single longitudinally extending guide channel in the lower part of said guide ramp.
