Abstract
The utility model provides a belt conveyor. The belt conveyor comprises a rack, a carrier roller and a roller which are arranged on the middle section of the rack, a head end turnabout roller and a tail end turnabout roller which are arranged at the two ends of the rack, and a belt sleeved on the carrier roller, the roller, the head end turnabout roller and the tail end turnabout roller; the belt conveyor also comprises a feeding cylinder and an air blowing port; an outlet of the feeding cylinder is positioned on the left of the head end turnabout roller and above the upper layer of the belt; the air blowing port is positioned on the left of the head end turnabout roller and on the upper surface and the lower surface of the lower layer of the belt; the feeding cylinder and the air blowing port are connected with an air supply pipeline system. The belt conveyor has the beneficial effects that materials uniformly flow onto the belt of the belt conveyor under the condition of uniform distribution left and right, so that sticky material on the belt is effectively cleaned, and the deflection of the belt since local cylinder diameter of the carrier roller or the roller becomes larger is prevented.
Description
Technical field
The utility model relates to coal feedway field, especially relates to a kind of belt conveyor.
Background technology
At present, along with China is outdoor and the fast development of underground mine, the raising of comprehensive mechanical automation, the increase of productive capacity, belt conveyor plays leading position in coal production transport systems, is the important tool of coal production transportation.Open coal mine is semicontinuous and continuous exploitation is produced rock, coal transportation, the one continuous line lifting of underground mine coal and the Coal Transport system of transportation, ground production system and coal preparation plant have all adopted belt conveyor in a large number, are developed into so far the large-scale belt conveyor of the nearly 10Km of separate unit length by past small-sized belt conveyer.
Fault common when belt conveyor operation is as follows: the sideslip that 1, cylinder, carrying roller sizing cause, belt conveyor is after operation a period of time, because part convey materials can be bonded on cylinder or carrying roller, make the local barrel dliameter of cylinder or carrying roller become large, cause that belt both sides tensile force is inhomogeneous, cause belt deviation; 2, the sideslip that convey materials skewness causes, if belt not sideslip of when idle running, heavy load turns round with regard to sideslip, illustrate that material is at belt both sides skewness, material skewness is mainly that material falling direction and malposition cause, if material is biased to left side, belt is gone around to the right, and vice versa; 3, in the time of material flow inequality, destroy belt conveyor harmony, cause local overload, cause belt wearing and tearing aggravation, often so can cause the generation of the accident of belt fracture, impact is normally produced.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of belt conveyor is provided.
The technical solution of the utility model is:
Belt conveyor, comprises frame, is arranged on carrying roller and cylinder on described frame stage casing, is arranged on head end bend pulley and the tail end bend pulley at described frame two ends, and is enclosed within the belt on described carrying roller, cylinder, head end bend pulley and tail end bend pulley,
Also comprise feeding cylinder and blowing mouth, the outlet of described feeding cylinder is positioned at the top on the upper strata of described head end bend pulley left and described belt, and described feeding cylinder becomes obtuse angle with the angle of the service direction on the upper strata of described belt,
Described blowing mouth is positioned at upper surface and the lower surface of the lower floor of described head end bend pulley left and described belt, and the angle of the service direction of the lower floor of described blowing mouth and described belt acutangulates,
The bottom surface of the upper part of described feeding cylinder offers some breather ports, and described feeding cylinder is connected with giving wind pipeline system by described breather port, and the described wind pipeline system of giving is connected with described blowing mouth by pipeline.Make material produce the uniform effect of secondary, make to flow on the belt of belt conveyor in material is even, left and right is uniform situation, and bilevel blowing mouth, the sizing on effectively clean belt, prevent that the local barrel dliameter of cylinder or carrying roller from becoming large, the belt deviation phenomenon causing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, head end bend pulley 2, belt 3, feeding cylinder
4, blowing mouth 5, breather port 6, give wind pipeline system
The specific embodiment
As shown in Figure 1, the utility model comprises frame, is arranged on carrying roller and cylinder on described frame stage casing, is arranged on head end bend pulley 1 and the tail end bend pulley at described frame two ends, with the belt 2 being enclosed within on described carrying roller, cylinder, head end bend pulley 1 and tail end bend pulley
Also comprise feeding cylinder 3 and blowing mouth 4, the outlet of described feeding cylinder 3 is positioned at the top on the upper strata of described head end bend pulley 1 left and described belt 2, and described feeding cylinder 3 becomes obtuse angle with the angle of the service direction on the upper strata of described belt 2,
Described blowing mouth 4 is positioned at upper surface and the lower surface of the lower floor of described head end bend pulley 1 left and described belt 2, and described blowing mouth 4 acutangulates with the angle of the service direction of the lower floor of described belt 2,
The bottom surface of the upper part of described feeding cylinder 3 offers some breather ports 5, and described feeding cylinder 3 is connected with giving wind pipeline system 6 by described breather port 5, and the described wind pipeline system 6 of giving is connected with described blowing mouth 4 by pipeline.
The width of the length of the outlet of described blowing mouth 4 and described belt 2 is roughly the same, and the mouth end of described blowing mouth 4 and the distance of belt 2, should be along the Width distance of belt 2 evenly, described blowing mouth 4 can be a blowing mouth, also can be connected to form side by side by several blowing mouths.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
