Abstract
The invention relates to a semi-wedge type roller applied in coal cutter of coal mining equipment. In order to improve the block coal rate, a novel coal cutting theory and structure are adopted. The semi-wedge type roller is different from the conventional rollers mainly in three parts: the cutting disc (1), the wedge block (2), and the spiral blade (3). The cutting disc (1) is similar to the end plate in the conventional rollers and is used to dig a groove on the coal wall. The external surface of the wedge block (2) is a spacial inclined plane, the wedge block (2) is inserted into the groove as the coal cutter is moving forward, and the coal on the external side of the groove is cut off through the movement of the coal cutter and the rotation of the roller. The external edge of the spiral blade is in a shape angle shape and is not provided with any cutting pick, the spiral blade (3) is mainly used to store coals, and when the coals are not cut off, the sharp angle of the external edge of the spiral blade (3) will cut off the coals to assist the coal cutting.
Description
Technical field
The present invention relates to section wedge-type cylinder that in a kind of coal mine equipment, coal-winning machine is used.
Background technology
For a long time, the cylinder that coal-winning machine uses be all whole section at cylinder dark on pick setting, i.e. pick setting all on end plate and helical blade.By coal-winning machine walking propelling and drum rotating, the coal on rib is cut.Although the pick arrangement difference on cylinder, its transversal distance all, between 30-50mm, causes the too fragmentation of coal of being got off by cut.Especially near the coal of rib side, cut to fall behind in and pushed to can be repeated by the pick on helical blade in the process of scratch board conveyor broken by helical blade, cause lump coal rate extremely low.Design coarse coal cylinder for improving some producers of lump coal rate, its principle is on the basis of former cylinder, to strengthen transversal distance, lengthens pick, reduces the pick quantity on cylinder.Although this cylinder can improve lump coal rate, but still defectiveness, be first whole section of cylinder dark on pick settings all, still there is the broken problem that repeats, it is few that lump coal rate improves.Next is to strengthen transversal distance owing to reducing pick quantity, and the load of single pick is strengthened, and because pick lengthening force-bearing situation is bad, therefore this cylinder service condition is limited, is only suitable for the ature of coal that hardness is low.
Summary of the invention
In order to solve the low problem of present widely used cylinder lump coal rate, the present invention has adopted a kind of new coal cutting principle, forms and cuts wedge-type cylinder.
The technical solution adopted for the present invention to solve the technical problems is:
Retain the end plate of now conventional cylinder, by rearranging the pick on end plate, making its original opening help Functional change is kerf function, goes out groove, therefore called after bottom jib when work at the inboard cut of rib.
Middle part at bottom jib arranges voussoir, and the external surface of voussoir is inclined-plane, space.When work, voussoir can be wedged the groove that bottom jib is outputed along with coal-winning machine walking, and relies on the thrust of coal-winning machine walking and the power of drum rotating that the coal wedge cleaving in groove outside is got off, and it is block that the coal being got off by wedge cleaving keeps mostly.
Retain the helical blade on now conventional cylinder, helical blade height is cancelled and shortened to the pick on helical blade, its outer rim is with wedge angle.Helical blade after change can be pushed scratch board conveyor to the coal falling, and realizes the function of coalingging.The wedge angle of outer rim can be assisted coal cutting, in the time having voussoir to fail coal that wedge cleaving gets off, splits down by it.Due to the pick of having cancelled on it, reduce the repetition fragmentation of the lump coal that wedge cleaving is got off, ensure the raising of lump coal rate.
The terminal pad and the cylinder hub that retain now conventional cylinder, connect for same rocker arm of coal mining machine.
The invention has the beneficial effects as follows:
Improve lump coal rate.The price of lump coal is the more than two times of fine coal price, same coal resources, and the economic benefit that same workload produces but improves greatly.
Energy-conservation.The lump coal that the coal getting off owing to slotting except bottom jib, most coal is got off by wedge cleaving, and cancel the pick on helical blade, reduce the energy that unnecessary fragmentation consumes, therefore can reduce the power of coal-winning machine cutting motor, more energy-conservation than existing cylinder.
Environmental protection, safety.Due to the unnecessary fragmentation having reduced coal, the dust producing while making coal-winning machine work reduces greatly, has improved workman's working environment, and has reduced the possibility of dust explosion.
Reduce costs.Owing to having lacked the pick on helical blade, reduce the material consumption of this part pick, can reduce producing coal cost.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further described.
Accompanying drawing is the constructional drawing that cuts wedge-type cylinder.
In figure:
1, bottom jib; 2, voussoir; 3, helical blade; 4, tie-plate; 5 hubs
Detailed description of the invention
With reference to accompanying drawing, bottom jib 1 is welded as a whole with helical blade 3, tie-plate 4, cylinder hub 5, bottom jib 1 outer rim is arranged pick, for the coal in the groove that ensures to output can be discharged smoothly, and groove two is helped not and toothholder friction, groove width should be 200mm left and right (concrete size will according to bottom jib 1 diameter adjustment).Voussoir 2 is placed between the outer rim and helical blade 3 of bottom jib 1, external surface is inclined-plane, space, incline direction is corresponding with the rotation direction of cylinder, when work, voussoir can be wedged the groove that bottom jib 1 is outputed along with coal-winning machine walking, and rely on the thrust of coal-winning machine walking and the power of drum rotating that the coal wedge cleaving in groove outside is got off, therefore voussoir 2 use high-abrasive materials are made or add wearing layer at its external surface.Because voussoir 2 is consumable accessory, therefore should make dismountable individual part.Its distributed quantity is definite according to the size of bottom jib 1 diameter, and inclined-plane, space Angular Dimension will be determined according to rolling groove width and ature of coal hardness.Helical blade 3 is welded on a hub, and the rotation direction of helical blade 3 is corresponding with the rotation direction of cylinder, and to push scratch board conveyor to by cutting the coal falling, outer rim wedge angle and old man's side surface of helical blade 3 will have wearing layer, to increase the service life.Within tie-plate 4 is placed in a hub, for connecting with rocker arm of coal mining machine, its square hole size and bolt hole size will be determined according to the cylinder coupling sleeve size in rocker arm of coal mining machine.Cylinder hub 5 links together bottom jib 1, helical blade 3, tie-plate 4 to form the main body group welding piece that cuts wedge-type cylinder.
Claims (3)
1. cut a wedge-type cylinder, comprise bottom jib, voussoir, helical blade, it is characterized in that being equipped with on bottom jib voussoir.
2. according to claim 1 section of wedge-type cylinder, is characterized in that voussoir external surface is with inclined-plane, space.
