Abstract
The utility model belongs to belt-type feeding machines used in the field of mining production conveying, and particularly relates to a frictional force increasing device for a conveyor belt used for a belt-type feeding machine. The frictional force increasing device comprises a conveyor belt and a driving roller, wherein the conveyor belt is wound on the driving roller to form a circular arc-shaped curved surface. The frictional force increasing device is characterized by further comprising a pressing roller component, a pressing bar component, a heavy hammer, and a lug ring connected onto a rack; the cylindrical outer surface of the pressing roller is placed at the position tangential with the circular arc-shaped curved outer surface of the conveyor belt; the dead weight of heavy hammer is transferred onto the conveyor belt through the pressing bar component, as a result, the pressure between the conveyor belt and the driving roller is increased, and accordingly the frictional force between the conveyor belt and the driving roller is increased. The frictional force increasing device provided by the utility model has the benefits that the specifications of the conveyor belt, the roller, a bearing and the rack are lowered, and the manufacturing cost of the whole machine is lowered.
Description
Technical field
The utility model belongs to the apron feeder using in mining industry production transportation art, is specifically related to belt conveyor friction force aggrandizement apparatus for a kind of apron feeder.
Background technology
Apron feeder power consumption is little, takes up room little, and feeding coal is large, easy to use, so closely Shi Yunian bargh has obtained promoting the use of on a large scale, for national product has been made the large contribution of tool.Apron feeder has an endless belt conveyer, and head roll is established in belt conveyor one end, and the other end is established bend pulley, divide into some carrying rollers, head roll rotates, and by friction force, drives belt conveyor to make circulating motion, thereby material is transported to the other end by one end, completes feed function.
Traditional apron feeder, in order to make to produce enough large friction force between head roll and belt conveyor, often needs to increase the tensile force of belt conveyor, then positive pressure increase, thus increase the friction force between them.This method is really effectively simple, uses now very extensive.
But this method is defectiveness also.Tensile force, a part is in order to transmit material, carrying material gravity and necessary, and another part is extra increasing for increasing friction force.Increase tensile force, must make on the one hand to transmit with enough tensile strengths, on the other hand, must make cylinder, rack construction part etc. there is enough rigidity, thereby make the stressed system of whole apron feeder in state of equilibrium, like this, will certainly increase manufacturing cost.
Summary of the invention
The purpose of this utility model is to provide a kind of effectively increasing friction force, does not need again the apron feeder friction force aggrandizement apparatus of too large tensile force.
The utility model is achieved through the following technical solutions: i.e. a kind of apron feeder friction force aggrandizement apparatus, comprise press roll component, depression bar assembly, weight, belt conveyor, head roll and be connected to the earrings in frame, press roll component comprises two pressure rollers, two bearing assemblies and an axle, bearing assembly comprises stay bearing plate and two bearings, bearing fit on respectively with two bearing assemblies of spindle nose at pressure roller two ends is connected, axle is used for supporting two bearing assemblies, it is kept the distance and become a firm integral body, two pressure roller axis parallels.Belt conveyor is wrapped on head roll, forms arc-shaped surface.The axis parallel of pressure roller and head roll, and pressure roller cylindrical outer surface in the tangent position of belt conveyor arc-shaped surface outside face, contact site is two straight lines.Depression bar assembly comprises depression bar and bearing pin, and depression bar and bearing pin are fixed together, porose on depression bar, and axle cooperation, forms hinge, and press roll component and depression bar assembly are coupled together.Bearing pin and earrings are connected to form hinge, and the other end of depression bar is connected with weight.
Under the effect of weight deadweight, depression bar assembly has the trend of rotating around bearing pin, strength will be sent to press roll component by hinge like this, press roll component can send strength to two lines of tangent position on belt conveyor again, so belt conveyor will compress head roll herein, thereby improved the friction force between belt conveyor and head roll.
The present invention uses two pressure rollers, to contact because the combination of two pressure rollers can make to form well line between pressure roller and belt conveyor, if select a pressure roller, can be because the reason of manufacturing errors causes the axial line of pressure roller and head roll not parallel, form minute angle deviation, form some contact, result can cause belt conveyor sideslip, thereby affects result of use.
The present invention does not improve the tensile force of belt conveyor, but improved the friction force between belt conveyor and head roll, so, during type selecting belt conveyor, just do not need too high specification, can reduce tensile strength, the rigidity of cylinder and frame also can correspondingly reduce, the specification of roller bearings also can reduce, so reduced the manufacturing cost of complete machine.
The beneficial effects of the utility model are: the specification of belt conveyor, cylinder, bearing, frame reduces, and the manufacturing cost of complete machine reduces.

The specific embodiment
Example 1: as Fig. 1, shown in Fig. 2 and Fig. 3, apron feeder friction force aggrandizement apparatus comprises press roll component 1, depression bar assembly 2, bob-weight 3, belt conveyor 4, head roll 5 and be connected to the earrings 6 in frame, press roll component 1 comprises two pressure rollers 1.1, two bearing assemblies 1.3 and an axle 1.2, bearing assembly 1.3 comprises stay bearing plate and two bearings, bearing fit on respectively with two bearing assemblies 1.3 of spindle nose at pressure roller 1.1 two ends is connected, axle 1.2 is for supporting two bearing assemblies 1.3, it is kept the distance and become a firm integral body, two pressure roller 1.1 axis parallels.Belt conveyor 4 is wrapped on head roll 5, forms arc-shaped surface.The axis parallel of pressure roller 1.1 and head roll 5, and its cylindrical outer surface in the belt conveyor 4 tangent positions of arc-shaped surface outside face, contact site is two straight lines.Depression bar assembly 2 comprises depression bar 2.1 and bearing pin 2.2, and depression bar 2.1 and bearing pin 2.2 are fixed together, as shown in Figure 3, porose 2.3 on depression bar, and axle 1.2 coordinates, and forms hinge, and press roll component 1 and depression bar assembly 2 are coupled together.Bearing pin 2.2 and earrings 6 are connected to form hinge, and as shown in Figure 2, earrings 6 is fixed in frame, and the other end of depression bar 2.1 is connected with weight 3.
Under the effect of weight 3 deadweights, depression bar assembly 2 has the trend around bearing pin 2.2 rotations, strength will be sent to press roll component 1 by hinge like this, press roll component 1 can send strength to two straight lines of tangent position on belt conveyor again, so belt conveyor 4 will compress head roll 5 herein, positive pressure increases between the two, thereby has improved friction force.
The present invention uses the combination of two pressure rollers 1.1, and between belt conveyor 4, form well line contact, if select a pressure roller, can be because the reason of manufacturing errors causes the axial line of pressure roller and head roll 5 not parallel, form minute angle deviation, form some contact, result can cause belt conveyor 4 sideslips, thereby affects result of use.
The present invention does not improve the tensile force of belt conveyor, but improved the friction force between belt conveyor and head roll, so, during type selecting belt conveyor, just do not need too high specification, can reduce its tensile strength, the rigidity of cylinder and frame also can correspondingly reduce, the specification of roller bearings also can reduce, so reduced the manufacturing cost of complete machine.
