Mechanism for sorting
The present invention sorts through the material that mechanism for sorting 300 will pass through bag-breaking machine structure 200, makes material discharge from first discharge bucket 400 and 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 the size that can be used in according to material sorts.
In preferred implementation of the present invention, mechanism for sorting 300 can comprise sorting plate 310, and letter sorting plate 310 surrounds the transfer passage P of mechanism for sorting 300, and sorting plate 310 is provided with a plurality of sieve apertures (sieve diameter can be selected as required, for example 40-80mm).Wherein, One end of sorting plate 310 is connected with feed hopper 100; The other end of sorting plate 310 is connected with second discharge bucket 500; The inlet of the transfer passage P of mechanism for sorting 300 is communicated with the outlet of feed hopper 100, and the outlet of the transfer passage P of mechanism for sorting 300 is communicated with the inlet of second discharge bucket 500, and the bottom of sorting plate 310 is provided with first discharge bucket 400.After material got into the transfer passage P of mechanism for sorting from feed hopper 100, size was passed through sieve aperture less than the material (i.e. second material) of screen size, and discharged from first discharge bucket 400 that is positioned at sorting plate 310 belows; Size will be along the length direction of sorting plate 310 (from an end of sorting plate 310 towards the other end greater than the material (being thick foreign material) of screen size; Be Fig. 2 medium dip from left to right transfer passage direction downwards) move and discharge from second discharge bucket 500 that is positioned at sorting plate 310 other ends, thus accomplish letter sorting.Wherein, it is understandable that the two ends of sorting plate 310 should be tightly connected with the feed hopper 100 and second discharge bucket 500 respectively, the downside of sorting plate 310 should be tightly connected with first discharge bucket 400.
Preferably, sorting plate 310 is downward-sloping towards the other end from the end that it is communicated in feed hopper 100, promotes that to utilize the material self gravitation material moves along sorting plate 310, makes the discharging of carrying out through second discharge bucket 500 more smooth and easy.Accordingly, the height of 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 making full use of each sieve aperture on the sorting plate 310, thereby sorting plate 310 indent inner wall surface thereof are inner sunken face.For example, sorting plate 310 is the semicircle tubular, and its cross section can comprise outstanding arc downwards.Thus, the screening area in the sorting plate 310 increases, and material can carry out sufficient cross direction profiles under the effect of said curved surface, make full use of each sieve aperture on the sorting plate 310, has improved letter sorting efficient.
Preferably; Mechanism for sorting 300 of the present invention can also comprise pendulum rake device 320; This pendulum rake device 320 comprises the pendulum rake; Pendulum rake is used for also making the width reciprocally swinging of material along sorting plate 310 in the process that material is moved along sorting plate 310, and material is also moved along the width of sorting plate 310 when the length direction along sorting plate 310 moves under the toggle action of pendulum rake, finally makes material in sorting plate 310, move to the other end from an end with wriggling.That is to say that material moves back and forth along the width of sorting plate 310 on the one hand, the length direction along sorting plate 310 moves on the other hand.In the sinuous moving process of material; Material can move through the entire working surface of sorting plate 310, makes full use of the sieve aperture on the sorting plate 310, make in the material tiny material fully from sieve aperture through and discharge from first discharge bucket 400; Thereby make letter sorting more thorough, better effects if.In addition, the material that makes in the sorting plate 310 of stirring of pendulum rake acutely stirs, and has further improved letter sorting efficient.
For above-mentioned sorting plate 310, use pendulum rake device 320 to cooperate letter sorting can obtain best effect with curved surface (particularly cross section comprises arc).For this reason, can be designed to make the pendulum rake can sweep the entire working surface of the cylindrical portions may of sorting plate 310 pendulum rake device 320.Particularly; Pendulum rake device 320 comprises pendulum rake axle 321, and the pendulum rake is installed on the pendulum rake axle 321, and pendulum rake axle 321 is arranged on the central axis of cylindrical portions may; Promptly pass the center of circle of arc of the cross section of sorting plate 310, and the radius of the length of pendulum rake and said arc is roughly the same.Thus, through rotation pendulum rake axle 321, the pendulum rake can swing back and forth with 321 rotations of pendulum rake axle, realizes stirring.Wherein, pendulum rake axle 321 can drive and install in position through suitable driver part (for example motor), and for example the two ends of pendulum rake axle 321 can be connected to the feed hopper 100 and second discharge bucket 500 through bearing.
Pendulum rake of the present invention can adopt various suitable structures, swings back and forth as long as can be installed on the pendulum rake axle 321, thereby realizes that the function of dialling material, lifting gets final product.Preferably, pendulum of the present invention rake comprises installation portion and is installed in the arm on this installation portion, and said installation portion is provided with installing hole, is used to be installed in pendulum rake axle 321, for example can form tabularly, and said arm can form the 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 the pendulum rake swings back and forth; The inclined-plane at two waist places of isosceles triangle will produce the power of edge perpendicular to the direction on inclined-plane to material; This power can be decomposed into the longitudinal force and the cross force that is parallel to the width of sorting plate 310 of the length direction that is parallel to sorting plate 310, makes material when the length direction along sorting plate 310 advances, also advance along the width of sorting plate 310.
In addition, preferably, for the curved surface (particularly cross section comprises arc) that matees sorting plate 310, the bottom of the arm of pendulum rake forms the shape that the curved surface with sorting plate 310 is complementary.For example, when sorting plate 310 has cross section when being 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 the arc of the cross section of sorting plate 310, but radial dimension matees each other.Thus, during swing, fit with sorting plate 310 basically in the bottom of pendulum rake, eliminated the gap between pendulum rake and the sorting plate 310, avoided material to get into this gap and wearing and tearing pendulum rake and sorting plate 310.
In addition, the pendulum rake can comprise multiple structure and be used in combination.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 single armed pendulum rake 322 and both arms pendulum rake 323 axially can respectively be 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 that adjacent single armed is put rake 322, promptly put rake 322 and put rake 321 a formed planes symmetry about single armed.Thus, can be along pendulum rake axle 321 axially stir material continuously.Particularly; When two arms of both arms pendulum rake 323 are swept the two ends of a part of arc-shaped cross-section of sorting plate 310 respectively; These two arms can be stirred the material at this place, and two single armeds pendulum rakes 322 adjacent with this both arms pendulum rake 323 front and back can be stirred material at the middle part of the arch section of cross section before and after it.Through suitable swing speed is set; And between adjacent single armed pendulum rake 322 and both arms pendulum rake 323, suitable spacing is set; Basically can realize stirring material continuously, avoid stirring the inhomogeneous problems such as accumulation that cause of speed because of material along pendulum rake axle 321.Wherein, each both arms pendulum rake 323 can be set to identical position to, promptly laterally arrange, same, each single armed pendulum rake 322 also can laterally arrange.
Obviously, both arms pendulum rake 323 is bigger than the amplitude of stirring of single armed pendulum rake 322, and it is more violent to stir material.Therefore, near second discharge bucket 500,, can make the pendulum rake adjacent be set to single armed pendulum rake 322 with second discharge bucket 500 for the ease of discharging, so as not to material turning, kick up too much, thereby can improve discharging speed.On the contrary; In order to make the speed away position that is connected with feed hopper 100 of mechanism for sorting 300 of the material that gets into mechanism for sorting 300; Can make with feed hopper 100 adjacent pendulum rakes and be set to both arms pendulum rake 321, advance along sorting plate 310, avoid being deposited in this position to stir material rapidly.
In addition, according to preferred implementation of the present invention, sorting plate 310 comprises that two length directions along sorting plate 310 laterally arrange 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 convexity 310a is far below the both lateral sides of sorting plate 310; This convexity 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 that the cross section of sorting plate 310 has two continuous curved portions, these two curved portions preferably intersect setting at said protruding 310a.
Correspondingly; Pendulum rake device 320 also can comprise two pendulum rake axles 321 and a plurality of pendulum rakes that are installed on each pendulum rake axle 321; The axis of said two pendulum rake axles 321 passes the center of circle of the curved portions of said two sorting plate parts 311 respectively, in corresponding sorting plate part 311, to stir material through the pendulum rake on each pendulum rake axle 321 respectively.Wherein, for avoiding two mutual interference of pendulum rake on the pendulum rake axle 321, two pendulum on the pendulum rake axle 321 are harrowed with identical position to setting.
Preferably, like Figure 10 and shown in Figure 11, the position of an 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 set about the width centreline of sorting plate 310.In addition; The pendulum rake is swung to be higher than the position that curved portions intersects; Preferably make the arc length of the hunting range of pendulum rake greater than curved portions; Thus, the pendulum of a corresponding sorting plate part 311 rake 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.Through this layout, further increased the distance of flow of material, help material and evenly flow and increase the area that paves.In addition; When material is put rake when a sorting plate part 311 toggles it to another sorting plate part 311, the pendulum rake plays the lifting effect, helps material and touches the higher part in position in the sorting plate 310; Thereby make full use of the sieve aperture in the higher part in this position, improved the letter sorting effect.In addition, in conjunction with the sorting plate that is obliquely installed 310, material is put rake when kicking up, and along the bearing of trend of sorting plate 310, the drop point ratio is kicked up a little more near second discharge bucket 500, makes discharging more smooth and easy.In addition, adopt sorting plate 310, can reduce the radius of curved portions, also reduced the length of required pendulum rake thus, make and put rake device 320 miniaturizations with two continuous curved portions.
In addition, can be single armed pendulum rake 322 or both arms pendulum rake 323 on the correspondence position of two pendulum rake axles 321.Particularly; For a pendulum rake axle 321 in two pendulum rake axles 321; Single armed pendulum rake 322 can be set on the position of d with the one of which end, corresponding, in respective ends (preferably) single armed pendulum rake 322 or both arms pendulum rake 323 can be set on the position of d with another pendulum rake axle 321.It is understandable that, also can be on the correspondence position of two pendulum rake axles 321, the pendulum rake be set, promptly in two pendulum rake axles 321 one be provided with the pendulum rake at a distance of the position of d with the one of which end, and the pendulum rake can be set on another person's the relevant position.Preferably, the position of the pendulum rake on two pendulum rake axles 321 is to unanimity, and two pendulum rake axle 321 driven in synchronism, thereby makes two pendulum rake swings synchronously on the pendulum rake axle 321.That is to say that when the pendulum of the single armed on the pendulum rake axle 321 rake 322 was 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 also was positioned at the bottom of the curved portions of corresponding sorting plate part 311.
Preferably, like Fig. 8 and shown in Figure 9, drive unit is a drive motors 324, and transmission device is a six-bar mechanism, comprises the crank and rocker mechanism ABCD and the parallel-crank mechanism DCEF of series connection.Crank and rocker mechanism comprises crank AB, first connecting rod BC and the first rocking bar CD; Parallel-crank mechanism comprises the first rocking bar CD, second connecting rod CE and the second rocking bar EF; Crank and rocker mechanism ABCD and parallel-crank mechanism DCEF are through first rocking bar CD series connection; Crank AB is connected with the rotating shaft of drive motors 324 in the A point, and the first rocking bar CD is fixing with pendulum rake axle 321 in the D point, and the second rocking bar EF is fixing with pendulum rake axle 321 in the F point.Thus, when drive motors 324 started, drive motors 324 drove crank AB and rotates, and made to drive parallel-crank mechanism DCEF motion two pendulum rake axles 321 and rotate, and then make two pendulum rake swings synchronously on the pendulum rake axle 321 synchronously.
