Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1 to 4, the present invention includes grain barrel-removing 1, grain barrel-removing drives oil cylinder 2, and grain barrel-removing uprightly locks or unlocks the operating mechanism 3 of unloading, tilting grain barrel-removing drives oil cylinder 2 lower end and grain barrel-removing 1 lower hinge, hinged in the middle part of upper end and combine-harvester bin 4, grain barrel-removing 1 lower end and combine-harvester bin 4 lower hinge, operating mechanism 3 comprises stick control mechanism 31 and grain barrel-removing locking mechanism 32, grain barrel-removing locking mechanism 32 is arranged between combine-harvester bin 4 and grain barrel-removing 1, stick control mechanism 31 is arranged in driver's cabin, comprise handlebar 311, rocking arm 312, hydraulicdirectional control valve control stick 313 and steel wire pull line 314, in notch in the middle part of handlebar 311 lower end setting-in rocking arm 312, and be vertically fixedly connected with it.Hinged with the supporting seat 315 in driver's cabin in the middle part of rocking arm 312; rocking arm 312 left end is by control stick swivel pin 317 and hydraulicdirectional control valve control stick 313 upper end thereof; hydraulicdirectional control valve control stick 313 lower end and hydraulic inverting valve spindle 318 upper end thereof; it is hinged that rocking arm 312 right-hand member and steel wire pull line 314 left end pass through steel wire pull line swivel pin 316, and steel wire pull line 314 right-hand member is connected with grain barrel-removing locking mechanism 32 lower end.
As shown in Figure 3, grain barrel-removing locking mechanism 32 comprises lockplate 321, locking bar 322, back-moving spring 323 and locking bar supporting seat 324, lockplate 321 is in angle-square-shaped, be formed by fixedly connecting by securing member by two boards part, lockplate 321 is provided with lock hole 3211, and lockplate 321 right-hand member is weldingly fixed on on the left of in the middle part of grain barrel-removing 1.Locking bar 322 is positioned at the locking bar supporting seat 324 on the downside of lockplate 321, and locking bar supporting seat 324 takes the shape of the letter U, and shrouding 3241 is arranged at its top, and middle part is provided with transverse slat 3242.Locking bar supporting seat 324 is weldingly fixed on silo casing, locking bar 322 upper end passes the shrouding 3241 of locking bar supporting seat 324 upper end, corresponding with lock hole 3211 position being arranged on lockplate 321 outer end, locking bar 322 lower end is hinged with steel wire pull line 314 right-hand member stretched in locking bar supporting seat 324.Back-moving spring 323 is inserted in locking bar 322 upper end, its upper and lower side to be resisted against respectively on the downside of locking bar 322 intermediate flange 3221 and on the upside of transverse slat 3242 between.
As shown in Figure 4; rocking arm 312 left end is provided with deep-slotted chip breaker 3121; radius of curvature R of described deep-slotted chip breaker 3121 with in the middle part of rocking arm 312 with the hinged center of the supporting seat 315 in driver's cabin for the center of circle, hydraulicdirectional control valve control stick 313 upper end is hinged with rocking arm 312 left end by the swivel pin 317 through deep-slotted chip breaker 3121.Guarantee that the commutation of hydraulicdirectional control valve can normally be carried out, thus make grain barrel-removing drive oil cylinder 2 drive grain barrel-removing 1 to realize inclination unloading and regain upright.
When grain barrel-removing 1 is in upright lock-out state, as shown in Figure 4, now hydraulic inverting valve spindle 318 is in the meta of three position directional valve, and swivel pin 317 is at the lower limit position D of deep-slotted chip breaker 3121.
When needing to unlock grain barrel-removing 1, as shown in Figure 2 and Figure 4, handlebar 311 first pushes away left in direction by driver as shown in Fig. 4 arrow, the rocking arm 312 be fixedly connected with handlebar 311 lower end also rotates counterclockwise thereupon; rocking arm 312 right-hand member rises, and steel wire pull line 314 left end rising right-hand member is declined, and steel wire pull line 314 right-hand member pulls the locking bar 322 hinged with it to move down and presses down back-moving spring 323; locking bar 322 upper end is gone out of lock the lock hole 3211 of plate 321, thus grain barrel-removing 1 is unlocked.Then, handlebar 311 continues to rotate counterclockwise by driver, and control stick swivel pin 317 is first moved upwards up to upper extreme position along the deep-slotted chip breaker 3121 of rocking arm 312
ethen control stick swivel pin 317 moves down with rocking arm 312, thus promotion hydraulicdirectional control valve control stick 313 moves down, hydraulic inverting valve spindle 318 moves down and hydraulicdirectional control valve is commutated, grain barrel-removing drives outside cylinder piston rod 21 and moves on to position, and grain barrel-removing 1 rotates around it center and is clockwise to and skewedly carries out unloading.Complete grain barrel-removing 1 unlock after release handle bar 311, handlebar 311 automatically returns to neutral position, and hydraulic inverting valve spindle 318 also gets back to the meta of three position directional valve, and this hour locking lever 322 stretches out locking bar supporting seat 324 under the effect of back-moving spring 323.
It is contrary with aforementioned grain barrel-removing 1 releasing process that grain barrel-removing 1 is recovered to the operating process that then erectility be locked, handlebar 311 first pushes away to the right by driver; rocking arm 312 left end is pulled on hydraulicdirectional control valve control stick 313 by control stick swivel pin 317 and moves; hydraulic inverting valve spindle 318 moves hydraulicdirectional control valve is commutated; grain barrel-removing drives cylinder piston rod 21 to retract and puts in place, and grain barrel-removing 1 rotates around it center and rotates counterclockwise reset.In the reseting procedure of grain barrel-removing 1, lockplate 321 is pressed down when first touching locking bar 322, then when locking bar 322 upper end arrives lock hole 3211 position of lockplate 321, under spring 323 reset force promotes, locking bar 322 upper end is stretched in the lock hole 3211 of lockplate 321, thus locking grain barrel-removing 1.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of application claims.
