Mechanism for sorting
The present invention sorts the material through broken bag mechanism 200 by mechanism for sorting 300, and material is discharged from the first discharge bucket 400 and the second discharge bucket 500 respectively according to size.
Mechanism for sorting 300 of the present invention can adopt suitable type and structure, as long as can be used according to the size of material, sorts.
In the preferred embodiment of the present invention, mechanism for sorting 300 can comprise sorting plate 310, and sorting plate 310 surrounds the transfer passage P of mechanism for sorting 300, is provided with a plurality of sieve apertures on sorting plate 310.Wherein, one end of sorting plate 310 is connected with feed hopper 100, the other end of sorting plate 310 is connected with the second discharge bucket 500, the entrance of the transfer passage P of mechanism for sorting 300 is communicated with the outlet of feed hopper 100, the outlet of the transfer passage P of mechanism for sorting 300 is communicated with the entrance of the second discharge bucket 500, and the bottom of sorting plate 310 arranges the first discharge bucket 400.Material is from feed hopper 100 enters the transfer passage P of mechanism for sorting, and size is less than the material of screen size by sieve aperture, and discharges from being positioned at the first discharge bucket 400 of sorting plate 310 belows; The material that size is greater than screen size by the length direction along sorting plate 310 (from one end of sorting plate 310 towards the other end, be down transfer passage direction from left to right of Fig. 1 medium dip) mobile and discharge from being positioned at the second discharge bucket 500 of sorting plate 310 other ends, thus complete sorting.Wherein, be understandable that, the two ends of sorting plate 310 should be tightly connected with feed hopper 100 and the second discharge bucket 500 respectively, and the downside of sorting plate 310 should be tightly connected with the first discharge bucket 400.
Preferably, one end that sorting plate 310 is communicated in feed hopper 100 from it is downward-sloping towards the other end, to utilize material self gravitation to promote material to move along sorting plate 310, makes the discharging undertaken by the second discharge bucket 500 more smooth and easy.Accordingly, the height of the second discharge bucket 500 is lower than feed hopper 100.Preferably, the bearing of trend of sorting plate 310 is 10～20 ° with respect to the inclination angle of horizontal direction.
In addition, for make material as far as possible along the distribution of the width of sorting plate 310 to make full use of each sieve aperture on sorting plate 310, thereby sorting plate 310 indent inner wall surface thereof are inner sunken face.For example, sorting plate 310 is semicircle tubular, and its cross section can comprise outstanding arc downwards.Thus, the screening area change in sorting plate 310, material can carry out sufficient cross direction profiles under the effect of described curved surface, makes full use of each sieve aperture on sorting plate 310, has improved sorting efficiency.
Preferably, mechanism for sorting 300 of the present invention can also comprise pendulum rake device 320, this pendulum rake device 320 comprises pendulum rake, pendulum rake is for also making material along the width reciprocally swinging of sorting plate 310 in the process that material is moved along sorting plate 310, namely make material under the toggle action of pendulum rake when the length direction along sorting plate 310 moves also the width along sorting plate 310 move, finally make material wriggle in sorting plate 310 and move to the other end from one end.That is to say, material moves back and forth along the width of sorting plate 310 on the one hand, and the length direction along sorting plate 310 moves on the other hand.In the sinuous moving process of material, material can move through the whole working face of sorting plate 310, makes full use of the sieve aperture on sorting plate 310, makes the tiny material in material from sieve aperture, pass through and discharge from the first discharge bucket 400 fully, thereby make sorting more thorough, better effects if.In addition, the material making in sorting plate 310 of stirring of pendulum rake acutely stirs, and has further improved sorting efficiency.
For the above-mentioned sorting plate 310 with curved surface (particularly cross section comprises arc), with pendulum rake device 320, coordinate sorting can obtain best effect.The whole working face of the cylindrical portions that for this reason, pendulum rake device 320 can be designed to make pendulum rake can sweep sorting plate 310.Particularly, pendulum rake device 320 comprises pendulum rake axle 321, and pendulum rake is arranged on pendulum rake axle 321, and pendulum rake axle 321 is arranged on the central axis of cylindrical portions, through the center of circle of the arc of the cross section of sorting plate 3 10, and the length of pendulum rake and the radius of described arc roughly the same.Thus, by rotation pendulum rake axle 321, pendulum rake can swing back and forth with 321 rotations of pendulum rake axle, and realization is stirred.Wherein, pendulum rake axle 321 can for example, be driven and be installed in position by suitable driver part (motor), and for example the two ends of pendulum rake axle 321 can be connected to feed hopper 100 and the second discharge bucket 500 by bearing.
Pendulum rake of the present invention can adopt various suitable structures, swings back and forth, thereby realize the function of material toggling, lifting as long as can be arranged on pendulum rake axle 321.Preferably, pendulum rake of the present invention comprises installation portion and be arranged on the arm on this installation portion, and described installation portion is provided with installing hole, for being arranged on pendulum rake axle 321, for example, can form tabularly, and described arm can form triangular prism shape.Wherein, the cross section of arm is preferably isosceles triangle, and its summit is towards the outlet of the transfer passage of mechanism for sorting 300.Thus, when pendulum rake swings back and forth, the inclined-plane at two waist places of isosceles triangle will produce material along the power of the direction perpendicular to inclined-plane, this power can be decomposed into the longitudinal force of the length direction that is parallel to sorting plate 310 and be parallel to the cross force of the width of sorting plate 310, and material is also advanced along the width of sorting plate 310 when the length direction along sorting plate 310 advances.
In addition, preferably, in order to mate the curved surface (particularly cross section comprises arc) of sorting plate 310, the bottom of the arm of pendulum rake forms the shape that the curved surface with sorting plate 310 matches.For example, when sorting plate 310 has cross section and is the curved surface of arc, the bottom of the arm of pendulum rake also forms corresponding curved surface, and the arc size in the cross section of this curved surface can be less than the size of arc of the cross section of sorting plate 310, but radial dimension mates mutually.Thus, during swing, fitting with sorting plate 310 substantially in the bottom of pendulum rake, has eliminated the gap between pendulum rake and sorting plate 310, avoided material to enter this gap and worn and torn pendulum rake and sorting plate 310.
In addition, pendulum rake can comprise various structures and be combined with.For example, in embodiments of the present invention, pendulum rake comprises single armed pendulum rake 322 and both arms pendulum rake 323, along pendulum rake axle 321, axially single armed pendulum rake 322 and both arms pendulum rake 323 can be respectively set, and make two arms of both arms pendulum rake 323 be positioned at single armed pendulum rake 322 both sides, preferably make two arms of both arms pendulum rake 323 be symmetrically located at the both sides of adjacent single armed pendulum rake 322, symmetrical about single armed pendulum rake 322 and pendulum rake axle 321 formed planes.Thus, can be along pendulum rake axle 321 axially stir continuously material.Particularly, when two arms of both arms pendulum rake 323 sweep respectively the two ends of a part of arc-shaped cross-section of sorting plate 310, these two arms can be stirred the material at this place, and two the single armed pendulum rakes 322 adjacent with these both arms pendulum rake 323 front and back can be stirred material in the middle part of the arch section of cross section before and after it.By suitable swing speed is set, and between adjacent single armed pendulum rake 322 and both arms pendulum rake 323, suitable spacing is set, substantially can realize along pendulum rake axle 321 and stir continuously material, avoid stirring the inhomogeneous problems such as accumulation that cause of speed because of material.Wherein, each both arms pendulum rake 323 can be set to identical position to, be arranged in parallel, same, each single armed pendulum rake 322 also can be arranged in parallel.
Obviously, both arms pendulum rake 323 is larger than the amplitude of stirring of single armed pendulum rake 322, and turning over materials is more violent.Therefore, near the second discharge bucket 500, for the ease of discharging, can make the pendulum rake adjacent with the second discharge bucket 500 be set to single armed pendulum rake 322, so as not to by material turning, kick up too much, thereby can improve discharging speed.On the contrary, in order to make to enter the speed away position being connected with feed hopper 100 of mechanism for sorting 300 of the material of mechanism for sorting 300, can make the pendulum rake adjacent with feed hopper 100 be set to both arms pendulum rake 321, to stir rapidly material, along sorting plate 310, advance, avoid being deposited in this position.
In addition, according to the preferred embodiment of the present invention, sorting plate 310 comprises that two length directions along sorting plate 310 be arranged in parallel and interconnective sorting plate part 311, and each sorting plate part 311 comprises the bottom of outstanding curve form downwards.Thus, sorting plate 310 can form and have two continuous curved surfaces.In other words, one protruding 310a is formed on the bottom of sorting plate 310, this projection 310a is far below the both lateral sides of sorting plate 310, this projection 310a is divided into transfer passage P two grooves and sorting plate 310 is divided into two sorting plate parts 311, and these two grooves are set up in parallel and are interconnected along the length direction of sorting plate 310 is parallel.Preferably, the cross section of each sorting plate part 311 comprises curved portions.That is to say, the cross section of sorting plate 310 has two continuous curved portions, and these two curved portions preferably intersect and arrange at described protruding 310a.
Correspondingly, pendulum rake device 320 also can comprise two pendulum rake axles 321 and be arranged on a plurality of pendulum rakes on each pendulum rake axle 321, the axis of described two pendulum rake axles 321 passes respectively the center of circle of the curved portions of described two sorting plate parts 311, to stir material by the pendulum rake on each pendulum rake axle 321 in corresponding sorting plate part 311 respectively.Wherein, for avoiding two pendulum rakes on pendulum rake axle 321 mutually to interfere, preferably make two pendulum rakes on pendulum rake axle 321 be set by the same position.
Preferably, as shown in Figure 8 and Figure 9, the position of one end that is positioned at sorting plate 310 outsides of each curved portions is higher than the position of the other end of this curved portions.In addition, preferably, two sorting plate parts 311 are symmetrical arranged about the width centreline of sorting plate 310.In addition, can make pendulum rake swing to higher than the crossing position of curved portions, preferably make the hunting range of pendulum rake be greater than the arc length of curved portions, thus, the pendulum rake of a corresponding sorting plate part 311 can swing in another sorting plate part 311, and material is laterally toggled it to another sorting plate part 311 from a sorting plate part 311.By this layout, further increased the mobile distance of material, be conducive to material Uniform Flow and increase the area that paves.In addition, when material by pendulum rake when a sorting plate part 311 toggles it to another sorting plate part 311, pendulum rake plays lifting effect, is conducive to material and touches the higher part in position in sorting plate 310, thereby make full use of the sieve aperture in the higher part in this position, improved sorting effect.In addition,, in conjunction with the sorting plate 310 being obliquely installed, when material is kicked up by pendulum rake, along the bearing of trend of sorting plate 310, drop point ratio a little more close the second discharge bucket 500 of kicking up, makes discharging more smooth and easy.In addition, adopt the sorting plate 310 with two continuous curved portions, can reduce the radius of curved portions, also reduced thus the length of required pendulum rake, make 320 miniaturizations of pendulum rake device.
In addition, on the correspondence position of two pendulum rake axles 321, can be single armed pendulum rake 322 or both arms pendulum rake 323.Particularly, for a pendulum rake axle 321 in two pendulum rake axles 321, on the position of d, single armed pendulum rake 322 being set with its one end, corresponding, in the respective end with another pendulum rake axle 321, on the position of d, (preferably) single armed pendulum rake 322 or both arms pendulum rake 323 can be set.Be understandable that, also can on the correspondence position of two pendulum rake axles 321, pendulum rake be set, when one in two pendulum rake axles 321 on the position of d, be provided with pendulum rake with its one end, and on the relevant position of another one, pendulum rake can be set.Preferably, the position of the pendulum rake on two pendulum rake axles 321 is to unanimously, and two pendulum rake axles 321 synchronously drive, thereby two pendulum rakes on pendulum rake axle 321 are synchronously swung.That is to say, when the single armed pendulum rake 322 on a pendulum rake axle 321 is positioned at the bottom of curved portions of corresponding sorting plate part 311, the single armed pendulum rake 322 on another pendulum rake axle 321 is also positioned at the bottom of the curved portions of corresponding sorting plate part 311.
