Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with drawings and Examples.
As shown in Figure 1, the potato harvester that a kind of four-wheel tractor uses, comprises the large frame 3 with land wheel 13, and large frame 3 is as reaping machine integrated support, and each critical piece is all connected with it, and land wheel 13 is arranged on land axle 14, and the support of advancing is provided.Large frame 3 fronts arrange gearbox 4 and link 2 for being connected four-wheel tractor trifilar suspension pull bar, wherein gearbox 4 connects the power output of four-wheel tractor by spline joint axle 1, the output of gearbox 4 connects transmission main shaft 27, transmission main shaft 27 connects sprocket for main drive I 17 and sprocket for main drive II 18, sprocket for main drive I 17 connects the auxiliary driving sprocket wheel I 16 that is positioned at carrier bar conveying main spindle 15 one end by chain, carrier bar conveying main spindle 15 connects carrier bar by chain 5 and carries countershaft 28, carrier bar conveying main spindle 15 and carrier bar are carried between countershaft 28 transporting chain plate 29 are set, the other end of carrier bar conveying main spindle 15 arranges driving gear 6 and drive sprocket 7, driving gear 6 engages with the gear at the edge with in a toothrow wheel and adjacent gear meshed gears case 8, in gear-box 8, each gear is separately positioned on one end of eccentric shaft I 9 or eccentric shaft II 10, eccentric shaft I 9 and eccentric shaft II 10 are positioned at the rear position of large frame 3, the two eccentric direction is orthogonal, interleaved is arranged, another end is all fixed on large frame 3 with bearing 12, tail end at large frame 3 is provided with reaping machine pull bar 11, for fastening large 3.Sprocket for main drive II 18 connects the auxiliary driving sprocket wheel II 19 that is positioned at eccentric block 21 axle heads by chain, the axle in eccentric block 21 is arranged on bearing block 20.Eccentric block 21 connects the interlock plate 30 of below with digger blade 26 by eccentric ratio 22, and on eccentric ratio 22, cover has two sections of support springs 25 and stop nut, lays respectively at the both sides of interlock plate 30 tie points.Interlock plate 30 is connected on large frame 3 by rotary pin shaft 31 again, and interlock plate 30 belows arrange is fixed on the sanction soil dish 23 of cutting out on soil dish fixed axis 24.
Along front line direction, digger blade 26 and sanction soil dish 23 are positioned at forefront, and transporting chain plate 29 takes second place, and accepts the excavation thing of digger blade 26, and eccentric shaft I 9 and eccentric shaft II 10 subsequently, are accepted the transported substance of transporting chain plate 29.
The course of work of the present utility model and principle are:
Reaping machine is connected with the pull bar of four-wheel tractor by link 2, and whole potato harvester is fixed with large frame 3, by land wheel 13 support of advancing, the angle of penetration of potato harvester can by with the pull bar adjustment of four-wheel tractor.Power is first transferred to spline joint axle 1 by four-wheel tractor, be transferred to gearbox 4 by spline joint axle 1 again, by the power transmission after gearbox 4 speed changes to transmission main shaft 27, sprocket for main drive I 17 and sprocket for main drive II 18 on transmission main shaft 27 are also rotated thereupon, sprocket for main drive I 17 is rotated by chain-driving auxiliary driving sprocket wheel I 16, carrier bar conveying main spindle 15 rotates thereupon, the rotation that has driven carrier bar to carry countershaft 28 and transporting chain plate 29.Meanwhile, the rotation of auxiliary driving sprocket wheel I 16 has driven again the rotation of driving gear 6, and the gear in gear-box 8 rotates thereupon, and then has driven the rotation of staggered eccentric shaft I 9 and eccentric shaft II 10.
On the other hand, sprocket for main drive II 18 is rotated by chain-driving auxiliary driving sprocket wheel II 19, and then eccentric block 21 is also along with rotation, eccentric ratio 22 is just along with eccentric block 21 seesaws, thereby drive interlock plate 30 to do the oscillating motion around rotary pin shaft 31, so whole digger blade 26 also does the oscillating motion around rotary pin shaft 31, because eccentric ratio 22 front and back have support spring 25 to locate, interlock plate 30 and digger blade 26 just can only do oscillating motion within the specific limits.
Due to moving ahead of tractor, potato harvester also moves ahead thereupon, digger blade 26 has together dug soil and potato, digger blade 26 is connected with eccentric ratio 22 by interlock plate 30, the angle of penetration of digger blade 26 can be by the stop nut adjustment on support spring 25 both sides on eccentric ratio 22, determined the angle of penetration of digger blade 26 by the active length of two sections of springs, due to the cushioning effect of spring, digger blade 26 also can produce self-excited vibration in the time running into excavating resistance, cut out soil dish 23 soil on complete machine both sides is cut apart with a knife or scissors, thereby greatly reduced the resistance that complete machine travels.The potato having dug carries potato soil on one side to separate with soil on one side by transporting chain plate 29 backward, has reached the effect of first screening; The potato earth mixtures of initial gross separation is transported to staggered eccentric shaft I 9 and eccentric shaft II 10, staggered eccentric shaft I 9 and eccentric shaft II 10 have good separating effect, the soil of potato epidermis is peeled off, and potato is just transported to complete machine and tiles after one's death on the ground.
