The shift fork of described pull-fork assembly is stepped, and the angle of step-like first section skew lines and horizontal plane is the 30-40 degree; Installing hole and a torsion spring installing hole of a bearing pin two are arranged on the shift fork, and there is an inverted "L" shaped boss centre of shift fork for one section; Described fixture block is positioned on the dedicated aluminium alloy guide rail also movable with the classification chain.
The fixture block of described pull-fork assembly is provided with two chain installing holes, and the fixture block inboard is equipped with four skewed slots along the chain mounting hole site; The fixture block outside be provided with one with holes circular spacing and one microscler spacing, round boss with holes in addition, the top of this round boss is provided with an aperture, on the fixture block trundle is housed also, this trundle connects by bearing pin, two ends are fixed with jump ring.
Described classification chain outer plate is provided with two kinds and has strong market potential, and by above-mentioned having strong market potential fruit cup assembly and pull-fork assembly is installed respectively.
The invention belongs to a kind of improvement to prior art, it compared with prior art has the following advantages:
1, the utility model requires low to electromagnet action control in the fruit grading process, and the electromagnet stroke is short; the very little angle of rocking arm swing just can realize automatic classification (angle is between 10 degree-20 degree); help prolonging electromagnet service life; the while can be realized the high speed classification, raising fruit grading equipment productivity.
2, the utility model rocking arm in the fruit grading process because the acting in conjunction of rocking arm deadweight and torsion spring can adapt to circulation next time automatically, and can not lose efficacy owing to fractures such as torsion spring cause classification mechanism after classification.
3, a trundle is arranged on the utility model fixture block, replace sliding friction with rolling friction, thereby effectively reduce motor power consumption.

The specific embodiment
Label in the accompanying drawing is: 1, classification chain; 2, pull-fork assembly; 3, fruit cup assembly; 4, fixture block; 5, shift fork; 6, torsion spring; 7, bearing pin two; 8, jump ring; 9, dedicated aluminium alloy guide rail; 10, bearing pin installing hole; 11, torsion spring installing hole; 12, inverted "L" shaped boss; 13, trundle; 14, bearing pin; 15, circle with holes is spacing; 16, round boss; 17, aperture; 18, microscler spacing; 19, chain installing hole; 20, skewed slot; 21, outer plate; 22, the installation of fruit cup assembly is had strong market potential; 23, the installation of pull-fork assembly is had strong market potential.
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in Figure 1, the utility model is by classification chain 1, and pull-fork assembly 2 and fruit cup assembly 3 three parts are formed.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 9, this hierarchical chain comprises drive sprocket, driven sprocket and classification chain 1, wherein classification chain 1 is located on drive sprocket (removing) and the driven sprocket (removing), on classification chain 1, be provided with pull-fork assembly 2 and fruit cup assembly 3, and arrange pull-fork assembly 2 and fruit cup assembly 3 spaces, pull-fork assembly 2 comprises shift fork 5, and pull-fork assembly 2 is installed on the classification chain 1, and shift fork 5 can be swung, described pull-fork assembly 2 is by fixture block 4, shift fork 5 and torsion spring 6 are formed, shift fork 5 is stairstepping, realizes being connected with fixture block 4 by bearing pin 27, and two ends are fixing with jump ring 8.Be provided with classification executing agency below shift fork 5,4 of fixture blocks are along with classification chain 1 moves on dedicated aluminium alloy guide rail 9.
During work,, the fruit in the pallet is sent into corresponding sorting outlet, send by serial ports of computers according to previous Computer Processing result then by motor-driven classification chain 1, the result signal of single-chip microcomputer receiving computer, and call sorting control subprogram.After program is finished, transmit control signal, make the electromagnet mechanism action to corresponding sorting switch, stir corresponding shift fork 5 to 10 degree-20 degree, feasible fruit cup unstability, and under the gravity effect, fruit cup glides, thereby causes that fruit drops to corresponding outlet in the fruit cup, realizes sorting.After sorting finished, electromagnet mechanism recovered off-position, and shift fork recovers reset condition under torsion spring 6 and deadweight effect, waited for circulation next time.
As shown in Figure 4, the shift fork 5 of pull-fork assembly 2 is stepped, and the angle of step-like first section skew lines and horizontal plane is the 30-40 degree, and installing hole 10 and a torsion spring installing hole 11 of a bearing pin two are arranged, middle one section has an inverted "L" shaped boss 12, is used for shelving fruit cup assembly 3.Described shift fork 5 is stepped, makes shift fork 5 centre-of gravity shifts, thereby realizes that shift fork 5 is because of the gravity self-return.
As Fig. 5, Fig. 6, shown in Figure 7, the fixture block 4 of pull-fork assembly 2 is provided with two chain installing holes 19, is used for realizing and being connected of classification chain 1 that fixture block 4 inboards are equipped with four skewed slots 20 along the chain mounting hole site, so that the guiding during assembling; It is can prevent shift fork 5 because deadweight can not return when shift fork 5 runs to lower guideway along with hierarchical chain that fixture block 4 outsides are provided with one circular spacing 15 and one microscler spacing 18, wherein circular spacing 15 with holes.Microscler spacing 18 is spacing when being used for shift fork 5 returns, and a round boss with holes 16 is arranged, and is used for installing bearing pin 27, and boss can reduce the contact area between shift fork 5 and the fixture block 4, thereby helps the electromagnet action.The top of boss 16 is provided with an aperture 17, is used to install little torsion spring 6; A trundle 13 also is equipped with in fixture block 4 upper ends, and trundle 13 connects by bearing pin 14, and two ends are fixed with jump ring, can effectively reduce the friction between fixture block and the lower guideway, thereby can effectively alleviate motor load.
As shown in Figure 8, have strong market potential by two kinds on classification chain 1 outer plate 21 and 22,23 fruit cup assembly 3 and pull-fork assembly 2 are installed respectively.
