专利汇可以提供Apparatus for plowing loose particulate material专利检索，专利查询，专利分析的服务。并且Apparatus is provided for guiding a plow device along a long wall face armored conveyor on the face side thereof. The plow device is adapted to be hauled reciprocally by a chain along the length of the conveyor or a portion thereof. The apparatus includes an L-shaped elongate member which has an upright limb and a lower limb. The upright limb is securable to a side of the conveyor and the lower limb constitutes the base of the apparatus. The upright limb has secured along its upper edge a tube for guiding the device and a substantially continuous horizontal chain guide member extending therefrom to define upper and lower chain races. A cover plate is provided and is releasably secured to the tube in sealing relationship therewith to prevent contamination of the races by loose material. The cover plate abuts the free end of the chain guide member but is spaced from the lower limb of the elongate member such that in use a part of the plow device can extend through the space to engage a chain in the lower race to be driven thereby.，下面是Apparatus for plowing loose particulate material专利的具体信息内容。

权利要求

1. In a mineral mining assembly including a long wall face armored conveyor having at least one side wall, a plow device, a chain, chain engagement means on the plow device, the chain being adapted to haus the device longitudinally of the conveyor whereby loose material is plowed onto the said conveyor by the device, a plow device guiding apparatus including a substantially L-shaped elongate member having an upright limb and a lower limb, the upright limb being securable to the side wall of the conveyor and the lower limb forming the base of the apparatus and extending from the upright limb beyond the plow device, a tubular member extending adjacently longitudinally of the upright limb thereby providing a support guideway for said device, a continuous chain guide member conneCted to the upright limb and extending therefrom, separate upper and lower chain races defined by said chain guide member, and a cover plate releasably secured to the tubular member, the cover plate abutting the free end of the chain guide member and terminating above said lower limb, whereby the chain engagement means of the plow device projects between the plate and the lower limb and engages the chain in the lower chain race.

2. Apparatus according to claim 1 wherein the chain guide member is situated on the upright limb of the substantially L-shaped elongate member and contacts each upright link in the chain located in the upper chain race.

3. Apparatus according to claim 1 wherein the chain guide member extends substantially horizontally from the upright limb whereby the chain runs extending through the races are arranged in substantially the same vertical plane.

4. Apparatus as claimed in claim 1 wherein the upright limb of the substantially L-shaped elongate member is sigma-shaped and has an upper flange to which is secured the tubular member, and the lower limb extends substantially horizontally from the upright limb.

5. Apparatus as claimed in claim 1 comprising a part secured to the substantially L-shaped elongate member and having an upper portion, the tubular member being formed integrally with said part along the said upper portion, and the chain guide member being secured to the said part and extending substantially horizontally therefrom.

6. Apparatus as claimed in claim 1 comprising a part secured to the upright limb of the substantially L-shaped elongate member, the part having an upper portion and a relatively lower portion, the tubular member being formed along said upper portion and the guide member being formed along said relatively lower portion.

7. Apparatus as claimed in claim 1 including locating recess means on the tubular member, the locating recess means being arranged in spaced relationship longitudinally of the member, and lugs on the cover plate, and lugs being correspondingly spaced and adapted to be accommodated in said locating recess means whereby the plate is positively located with respect to the tubular member, the plate sealably abutting the member whereby the ingress of material into the chain races is prevented.

8. Apparatus as claimed in claim 1 wherein the chain guide member is provided with an abutment.

9. Apparatus as claimed in claim 8 comprising fixing means for fixing the cover plate to the abutment.
