Abstract
The utility model relates to the technical field of coal ploughs for low coal seams of underground coal mines, and particularly relates to a coal plough head capable of realizing reciprocating staggered planing. The existing coal plough head is of a bilaterally symmetrical structure, two side planing tools at a same horizontal position always plane coal walls in a same plane, a convex coal ridge is reserved between adjacent two kerves, the coal walls are arranged in a W-shaped kerve mode, and in the process of planing the coal walls by a coal plough, the plough head needs to overcome a larger planing resistance, and coal bodies are difficult to cave. The coal plough head comprises a plough body and planing tools, wherein the plough body is of a symmetrical structure, a planing edge of each planing tool is of an offset structure, and the planing edges of the planing tools in two side tool aprons of the plough body are arranged in a staggered mode; or the plough body is of an asymmetric structure, and the left and right tool aprons are arranged in the staggered mode. The coal plough head disclosed by the utility model is small in relative intercept, small in exerted planing resistance, and high in adaptability to coal quality conditions of high toughness, difficult caving, and undeveloped coal bed joints, and the like.
Description
Technical field
The utility model relates to the coal plough technical field for thin seam mining under the coal mine, specifically a kind of back and forth coal planer plough of staggered planing of realizing.
Background technology
China's girdle aboundresources, it is wide to distribute, especially during southern coal measures consists of mainly take girdle as main, sharp increase along with coal demand, reasonable utilization and the exploitation of girdle resource have obtained unprecedented attention, and colliery urgent need compliance is good, reliability is high, the girdle of long haul distance fells and transports equipment.The coal plough that is used for thin seam mining under the coal mine splits that fief matter conditional request is higher, and the planer head of existing coal plough is the bilateral symmetry structure, is the intensity that guarantees shaping tool, and intercept is wider.In the shearing process, the both sides shaping tool of par position is all the time at same plane planing rib, the planing pattern is the plane cut, and is high in exploitation toughness, during obsolete coal seam, joint, coal body is difficult for avalanche, retained protruding coal ridge between adjacent kerf, rib presents the kerf of W form to be arranged, in coal plough planing rib process, planer head need to overcome larger ploughing resistance, the shaping tool serious wear.
Summary of the invention
The purpose of this utility model is to want to provide a kind of back and forth coal planer plough of staggered planing of realizing, the defective that exists to solve prior art improves the compliance of coal plough under the ature of coal conditions such as toughness height, difficult avalanche, coal bed joints agensis.
The technical solution adopted in the utility model is: comprise and dig body, shaping tool; The plane body is symmetrical structure, the planing sword of shaping tool is bias structure, shaping tool is installed in respectively in the tool rest that digs the body both sides, and the planing sword of the shaping tool of arranged on left and right sides is staggered and arranges the planing sword difference in height L of left and right two shaping tools of opposite position
2Be adjacent two the shaping tool difference in height L of homonymy
11/3～2/3.
Another technical scheme of the present utility model is: comprise and dig body, shaping tool; The plane body is unsymmetric structure, arranged on left and right sides tool rest interlaced arrangement, the difference in height L of both sides opposite position tool rest
4Be adjacent two the tool rest difference in height L of homonymy
31/3～2/3; The planing sword of shaping tool is symmetrical structure.
The planer head of coal plough moves back and forth the planing of finishing rib, in planing rib process, is subject to larger ploughing resistance, and especially under toughness height, the obsolete ature of coal condition in joint, coal body is difficult for avalanche.In the planing process, intercept is directly proportional with the ploughing resistance that shaping tool is subject to, but is subject to the restriction of shaping tool intensity, and intercept is unsuitable too small.The shaping tool of the opposite position arranged on left and right sides of the present invention's design is just staggered, so that double planing short transverse exists intercept poor, the planing pattern is staggered cut.Planer head planing process can be divided into two parts, the process of coal ridge between two kerfs that a part retains for the cut rib last time of planing, and the planing pattern is free cut in this process, is subject to from ploughing resistance and the specific energy consumption of rib minimum; Another part is the make new advances process of kerf of planing, and the planing pattern is the plane cut in this process.
The utility model has the advantages that: guaranteeing to reduce relative intercept in the situation that shaping tool and tool rest intensity do not reduce, the ploughing resistance that planer head is subject to is little, and is high to the compliance of the ature of coal conditions such as toughness height, difficult avalanche, coal bed joints agensis.
