专利汇可以提供Guide system for mine-planer blades专利检索，专利查询，专利分析的服务。并且A mine excavator such as a coal planer comprising a flight-type conveyor along the periphery of the conveyer trough or rail of which planer blades are provided to remove coal from the walls and floor of the excavation and direct the mass onto the conveyer. The guiding system for the planer blades comprises articulated guide segments mounted along the rails at the sides of the conveyer trough, limitedly movable in the vertical plane and grouped to include a pair of end segments separated by a central segment whose length is twice that of the end segments. The segments are hinged for relative angular movement about horizontal axes close to the floor-engaging (stress or impact) side of the assembly while successive pairs of central segments are interconnected by high-force constant flexing rods traversing the intervening end segments of two successive sets. The segments are held in a channel of the conveyer pan with limited freedom of up and down movement and are enabled to cant in a plane parallel to the rails.，下面是Guide system for mine-planer blades专利的具体信息内容。

权利要求

1. In a planer-type excavator, comprising a conveyer through having a longitudinal rail extending therealong, and a planerblade guide assembly mounted on said rail and forming a guide surface for the planer blades, the improvement wherein said rail has a longitudinally extending channel and said assembly comprises a plurality of groups of guide segments, having respective formations engaging with vertical play in said channel, means connecting said segments of each group together in succession at least along an impact-receiving side for limited relative canting movement of successive segments , and a rod connecting at least adjacent end elements of successive groups together with said vertical play.

2. In a planer-type excavator, comprising a conveyer through having a longitudinal rail extending therealong, and a planer-blade guide assembly mounted on said rail and forminG a guide surface for the planer blades, the improvement wherein said assembly comprises a plurality of guide segments, and means connecting said segments together in succession at least along an impact-receiving side for limited relative canting movement of successive segments, the last-mentioned means including respective hinges articulating a pair of end segments to a central segment close to said side, and a resiliently deflectable rod passing through at least one of said segments and anchored to another of said segments and arcuately deflectable upon stressing from said side for maintaining said segments normally in substantial alignment, said rod extending generally parallel to said rail.

3. The assembly defined in claim 2 and mounted on said rail together with at least one other similar adjacent assembly, said rod interconnecting the central segments of both said assemblies.

4. The assembly defined in claim 3 wherein said hinges include a lug extending in a longitudinal direction generally parallel to said rail from opposite ends of each central segment and a fork receiving the respective lug and formed on each of said end segments, said forks and the respective lugs being pivotally interconnected.

5. The assembly defined in claim 4 wherein each central segment is formed with a pair of recesses flanking each of its said lugs above and below the latter, said forks having respective extensions received within said recesses with limited play.

6. The assembly defined in claim 2, further comprising centering pins received between each end segment and the respective central segment for limiting the relative canting of each end segment and the respective central segment.

7. The assembly defined in claim 2 wherein said rail is formed with a laterally open longitudinally extending channel, each of said segments having a lateral projection received in said channel with limited play for restricting vertical displacement of said segment relative to said rail.

8. The assembly defined in claim 2 wherein said rail is formed with a laterally open channel and said segments are each provided with a plate received in said channel, and bolt means securing said plate to the respective segment while enabling limited vertical displacement of the segments relative to said rail.

9. The assembly defined in claim 2, further comprising a generally spheroidal joint connecting respective ends of said rod to each central segment.

10. The assembly defined in claim 9 wherein said rod is composed of a material having high tensile strength and spring force.

11. The assembly defined in claim 2 wherein each of said segments is provided with a laterally open longitudinally extending guide slot, further comprising a chain having a return pass traversing said slot.

12. The assembly defined in claim 11 wherein said slot is formed with a lower edge defining a weir across which excessive comminuted material collected in said slot is discharged.

13. The assembly defined in claim 12 wherein said segments are formed with a downwardly open passage receiving a forward pass of said chain.

14. The assembly defined in claim 13, further comprising scraper blades guided along said segments and having means extending into said passage and engaging said chain.
