Abstract
The utility model relates to a kind of small inclination elephant trunk, and described small inclination elephant trunk comprises support, be fixed on elephant trunk on support and plain-barreled roll belt feeder, and the main stress face that described plain-barreled roll belt feeder contacts with material as elephant trunk, substitutes steel plate, the patch portion of conventional elephant trunk; Angle between elephant trunk and ground is α, and by arranging less tilt angle alpha, the downward component utilizing material to produce drives belt to rotate, and makes material become the friction of rolling of plain-barreled roll belt feeder by cliding friction during elephant trunk, decreases waste of power; Solve small inclination elephant trunk material how quickly through problem.
Description
Technical field
The utility model relates to bulk material conveying industries, particularly relates to a kind of small inclination elephant trunk.
Background technology
Along with the development of modern logistics industry, the reprinting of material and unload a little increasing, therefore, elephant trunk use and layout becomes more and more important.Existing elephant trunk generally surrounds square barrel-like structure by steel plate, angle of inclination is generally arranged as 60 °, minimumly can not be less than 55 °, the elephant trunk of this kind of structure is while convey materials, material will produce larger relative sliding velocity with elephant trunk wall, therebetween produce fierce friction, like this, will arrange that a large amount of liner plate is to tackle wearing and tearing.Meanwhile, because leaning angle can not be less than 55 °, transfer point, the Dian Chu space of unloading of load transfer device arrange that height fall is large, need consume larger hoisting power.
Utility model content
In view of this, the utility model provides a kind of small inclination elephant trunk, passes through to ensure that material is smooth and easy, reduces the drop of material between feed and material feeding simultaneously.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of small inclination elephant trunk, comprise support, be fixed on elephant trunk on support and plain-barreled roll belt feeder, described plain-barreled roll belt feeder is positioned at the bottom of elephant trunk, and the belt of plain-barreled roll belt feeder is arranged in elephant trunk, and the angle between elephant trunk and ground is α.
Preferably, described angle α is 5 °-55 °.
Preferably, the belt width of described plain-barreled roll belt feeder is greater than the A/F of elephant trunk.
Preferably, the difference between the bandwidth of described belt and the A/F of elephant trunk is 50-150mm.
Small inclination elephant trunk described in the utility model, by arranging less tilt angle alpha, and a part of belt of plain-barreled roll belt feeder is arranged in elephant trunk, the downward component utilizing material to produce drives belt to rotate, make not produce relative sliding between material and belt, thus effectively reduce the wearing and tearing of adhesive tape.Because angle of inclination is little, then drop height in space can reduce.

Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of small inclination elephant trunk described in the utility model, and Fig. 2 is the birds-eye view of self-unloading elephant trunk described in the utility model.As shown in Figure 1, described small inclination elephant trunk 1 comprises support (not shown), the elephant trunk 2 be fixed on support, there is certain angle between described elephant trunk 2 and ground, material moves along the direction shown in arrow d in Fig. 1 in elephant trunk 2, until arrive the low side of elephant trunk.
As mentioned above, in the elephant trunk of this kind of structure, easily relative sliding is produced between the wall of material and elephant trunk 2, thus cause the wearing and tearing of material or elephant trunk wall, for overcoming this defect, small inclination elephant trunk 1 described in the utility model also comprises plain-barreled roll belt feeder 3, as depicted in figs. 1 and 2, described plain-barreled roll belt feeder 3 is positioned at the bottom of elephant trunk 2, and the bandwidth B of the belt 31 of plain-barreled roll belt feeder 3 is greater than the A/F B1 of elephant trunk 2, namely a part for plain-barreled roll belt feeder 3 is arranged in elephant trunk 2, another part is positioned at the outside of elephant trunk 2, material in elephant trunk 2 is positioned on plain-barreled roll belt feeder 3 and moves along the direction shown in above-mentioned arrow d, this kind of design effectively can prevent material from overflowing from elephant trunk 2 or trickle down, in the utility model embodiment, difference between the bandwidth B of described belt 31 and the A/F B1 of chute 2 is 50-150mm.
Fig. 3 is the principle of work schematic diagram of small inclination elephant trunk described in the utility model.As shown in the figure, this schematic diagram represents ground with solid line 5, and the angle between elephant trunk 2 and ground is α, and material 4 is arranged in elephant trunk 2, and be in be arranged in elephant trunk 2 belt on.
The force analysis of described material 4 as shown in Figure 3, (m is the quality of material to the self gravitation F=mg of material 4, g is acceleration due to gravity), the pressure of material 4 pairs of belts is F1=F*cos α=mg*cos α, component F2=F*sin α=mg*sin α that material 4 produces along the direction of arrow d in elephant trunk 2, the friction force F2 ' that belt produces material 4=μ * F1=μ * mg*cos α, as F2 > F2 ', i.e. mg*sin α > μ * mg*cos α, material 4 can drive plain-barreled roll belt feeder 3 to rotate, simultaneously, material 4 moves along the relative elephant trunk 2 in direction shown in arrow d.In the utility model embodiment, the scope of described elephant trunk inclination alpha is 5 °-55 °.
As mentioned above, the component F2 that material 4 produces along the direction of arrow d that meets arranged due to described angle α is greater than the friction force F2 ' of belt to material 4, therefore, plain-barreled roll belt feeder 3 can be driven by this downward component, simultaneously, drive the material 4 be positioned on belt to move along the direction shown in arrow d, now, between material 4 and belt, there is no relative sliding; Thus, when material 4 is by elephant trunk 2, the wearing and tearing between material and elephant trunk wall can effectively reduce, and material 4 can by the bottom being delivered to elephant trunk 2 of safety.
Elephant trunk 2 described in the utility model, by arranging less tilt angle alpha, and is arranged on (without steel plate on the downside of elephant trunk) on the downside of elephant trunk by plain-barreled roll belt feeder 3, and belt replaces the steel plate of elephant trunk bottom and becomes a part for elephant trunk.The downward component utilizing material 4 to produce drives belt to rotate, and makes material 4 and belt not have relative sliding, thus effectively reduces the wearing and tearing between material 4 and elephant trunk 2; Meanwhile, due to described tilt angle alpha arrange less, low-angle elephant trunk 2 described in the utility model also effectively can reduce the whole height of equipment, thus reduces the lifting power consumption of upstream equipment; Do not have relative sliding between material 4 and belt, therefore, material 4 steadily can arrive the bottom of elephant trunk 2, can effectively reduce the impact of material 4 pairs of upstream device material feedings place.
