Continuous miner having a sumping frame
View Patent ↗A continuous miner including a support frame having a support frame front, and a sumping frame mounted on the support frame for forward and rearward movement relative to the support frame. The sumping frame has a sumping frame front, and the miner further includes a cutting drum pivotally mounted on the sumping frame, the cutting drum being positioned near the sumping frame front. The miner also includes a gathering head for gathering mined minerals pivotally mounted on the sumping frame front, and a hydraulic cylinder for pivoting and fixing the gathering head relative to the sumping frame in both the raising and lowering directions. The continuous miner also includes a first drilling platform pivotally mounted on the support frame front, a second drilling platform pivotally mounted on the support frame front and spaced apart from the first drilling platform, a hydraulic cylinder for pivoting and fixing the first drilling platform relative to the support frame independently of the second drilling platform, and a hydraulic cylinder for pivoting and fixing the second drilling platform relative to the support frame independently of the first drilling platform.
1. A continuous miner including
a horizontal support frame having a support frame front,
a sumping frame mounted on said support frame for forward and rearward movement relative to said support frame, said sumping frame having a sumping frame front,
a cutting drum pivotally mounted on the sumping frame, said cutting drum being positioned near said sumping frame front,
gathering means for gathering mined minerals pivotally mounted on the sumping frame front,
means for pivoting and fixing said gathering means relative to said sumping frame in both the raising and lowering directions,
a first drilling platform pivotally mounted for vertical movement on the support frame front,
a second drilling platform pivotally mounted for vertical movement on the support frame front and spaced apart from the first drilling platform,
means for pivoting and fixing said first drilling platform relative to said support frame independently of said second drilling platform, and
means for pivoting and fixing said second drilling platform relative to said support frame independently of said first drilling platform.
2. A continuous miner in accordance with claim 1 wherein said first and second drilling platforms each include a support plate, and wherein each of said drilling platforms is pivotally mounted for vertical movement on said support frame front by each drilling platform including a first pivot arm on one side of said support plate and a second pivot arm on the other side of said support plate, and wherein each of said means for pivoting and fixing said drilling platform includes a hydraulic cylinder extending between said frame front and said drilling platform.
3. A continuous miner in accordance with claim 1 wherein said means for pivoting and fixing said gathering means includes a hydraulic cylinder extending between said frame front and said gathering head.
4. A continuous miner in accordance with claim 1 wherein said means for pivoting and fixing said gathering means includes two spaced apart hydraulic cylinders extending between said sumping frame front and said means for gathering mined minerals, each cylinder being on an opposite side of said gathering means.
5. A continuous miner in accordance with claim 1 wherein said gathering means is a gathering head.
