The main body has sets of cutters at its ends which are staggered in position. Guide members which are curved in a convex sense in relation to the floor of the mine working are located for sliding in correspondingly-shaped guideways in the main body. The guide members support floor cutters and the ends of the guide members can move along a path defined by the guideways projecting inwardly of the cutters relative to the body. Cotter pins locate in selected holes in the body to delimit the movement of the guide members and thereby define the operating positions of the floor cutters.，下面是Plough for use in mineral mining专利的具体信息内容。

权利要求

1. A coal plough comprising: a. an articulated multi-section sword plate; b. a main body supported by a central section of the sword plate; c. sets of cutting tools disposed near the ends of the main body; d. guide members of arcuate shape; e. guideways in the main body receiving the guide members for slidable movement along curved guide paths extending inwardly of the cutting tools relative to the main body; f. floor-level cutters carried by the guide members, said floorlevel cutters being capable of adopting various operating positions depending on the movement of the guide members along said guide paths; and g. means for engaging the guide members to define a range of permitted movement along said guide paths for said members whereby to set the operating positions of the floor-level cutters.

2. A plough as claimed in claim 1, wherein the last-named means consists of cotter pins insertable through bores passing through the plough body to the rear side thereof.

3. A plough as claimed in claim 2, wherein each arcuate guide member is associated with a group of such bores, each at a respective different height from the ground.

4. A plough as claimed in claim 3, including hinged flaps for covering the rear ends of the bores.

5. A plough for winning mineral from a mineral face, said plougH having a main body with sets of cutters located at the ends of the main body for cutting the face as the plough is moved, adjustable floor-level cutters arranged on guide members which are slidably displaceable in relation to said body to control the position of the floor-level cutters and along paths which extend inwardly of at least some of the cutters on the main body in relation to the body, a superstructure assembled from further bodies disposed one upon another and arranged on the main body, the further bodies carrying further cutting tools, the uppermost further body carrying a roof-cutter head having at least one cutting tool adapted to cut the mineral face at the upper part thereof, the roof-cutter head being adjustable in relation to the uppermost further body, said head having a guide portion located in a guideway of the uppermost further body, the guideway being inclined outwardly from the main body in a direction extending towards the lower part of the plough, the guide portion of the head being movable along the guideway to effect said adjustment.

6. A plough according to claim 5, wherein the guide portion of the head and the uppermost further body are provided with holes and a cotter pin can be inserted into selected aligned ones of the holes to secure the head in its desired position.

7. A plough for winning mineral from a mineral face, comprising: a. a sword plate constituted by a plurality of articulated sections, one of which is a central section; b. a main body supported by the said central sword plate section; c. a set of cutters carried by said body at each end thereof, certain of said cutters in each set being disposed successively outwardly from the body in a downward direction such as to leave a generally unobstructed trapezoidal space inwardly of the body; d. means extending across said space and defining two curved guideways; e. arcuate guide members bearing floor-level cutters, each guide member being supported by a respective guideway; f. a structure associated with the upper end of each guide member, said structure being traversed by a plurality of bores extending perpendicularly to said face; and g. a pin positionable in a selected bore to limit the extent of movement of each guide member in its guideway.
