Technical field
The present invention relates to a kind of united reaper discharge mechanism, especially a kind of control grain barrel-removing incline and open or uprightly close
The device for closing, belongs to agricultural machinery technological field.
Background technology
At present, the grain barrel-removing inclination opening of united reaper is changed into hydraulic pressure behaviour from manual control with reset shutoff device
Control.When grain barrel-removing carries out unloading operation, driver manipulates grain barrel-removing by hydraulic operation handle and drives that cylinder piston rod is overhanging pushes away
The outward-dipping unloading of dynamic grain barrel-removing；When united reaper carries out harvesting or traveling, grain barrel-removing is required to return to erectility,
To prevent to make united reaper ultra-wide because grain barrel-removing inclination is overhanging, scratch is caused to cause unnecessary to people and other objects
Personal injury and property loss.
When grain barrel-removing drives oil cylinder pressurize deficiency failure, overhanging grain barrel-removing usually can be inclined under gravitational moment effect automatically
Tiltedly open, and the driver in the anterior operation of united reaper is difficult to discover, it is easily accidents caused.Therefore need special to grain barrel-removing
Door installs erectility locking device, it is to avoid the accident that grain barrel-removing wing drop is opened occurs.Existing grain barrel-removing erectility
Locking device locks grain barrel-removing using anchor ear, and this structure needs the person's of sailing artificial operation of getting off to open anchor ear, after the completion of unloading again
Harvesting can just be proceeded after needing artificial locking anchor ear.It is cumbersome poorly efficient, increased the working strength of driver, shadow
Ring the working performance of united reaper.If driver forgets to unlock and directly operate grain barrel-removing to incline unloading, unloading can be also damaged
Cylinder erectility locking device and grain barrel-removing.

As shown in figure 3, grain barrel-removing locking mechanism 32 includes that lockplate 321, locking bar 322, back-moving spring 323 and locking bar are supported
Seat 324, lockplate 321 are in angle-square-shaped, are formed by fixedly connecting by securing member by two boards part, and lockplate 321 is provided with lock hole
3211,321 right-hand member of lockplate is weldingly fixed in the middle part of grain barrel-removing 1 on left side.Locking bar 322 is located at the locking bar on the downside of lockplate 321
In support base 324, locking bar support base 324 takes the shape of the letter U, and has shrouding 3241 at the top of which, and middle part is provided with transverse slat 3242.Locking bar support base
324 are weldingly fixed on silo casing, and 322 upper end of locking bar passes the shrouding 3241 of 324 upper end of locking bar support base, and are arranged on lock
3211 position of the lock hole correspondence of 321 outer end of fixed board, 322 lower end of locking bar and the steel wire pull line 314 stretched in locking bar support base 324
Right-hand member is hinged.Back-moving spring 323 is inserted in 322 upper end of locking bar, and its upper and lower side is born against on the downside of 322 intermediate flange 3221 of locking bar
And on the upside of transverse slat 3242 between.
As shown in figure 4,312 left end of rocking arm is provided with arcuate groove 3121, the radius of curvature R of the arcuate groove 3121 is with rocking arm
In the middle part of in the of 312 with drive indoor support base 315 be hinged center for the center of circle, 313 upper end of hydraulicdirectional control valve stick by through
The swivel pin 317 of arcuate groove 3121 is hinged with 312 left end of rocking arm.Guarantee that the commutation of hydraulicdirectional control valve can be normally carried out, so that
Obtaining grain barrel-removing drives the drive grain barrel-removing 1 of oil cylinder 2 to realize inclining unloading and withdrawing uprightly.
When grain barrel-removing 1 is in upright lock-out state, as shown in figure 4, now hydraulic inverting valve spindle 318 is changed in three
To the middle position of valve, lower limit position D of the swivel pin 317 in arcuate groove 3121.
When needing to unlock grain barrel-removing 1, as shown in Figure 2 and Figure 4, driver is first square as shown in Fig. 4 arrows by handlebar 311
To pushing away to the left, the rocking arm 312 being fixedly connected with 311 lower end of handlebar is also rotated counterclockwise therewith, and 312 right-hand member of rocking arm rises, and makes
Obtain 314 left end of steel wire pull line and rise right-hand member decline, 314 right-hand member of steel wire pull line is pulled the locking bar 322 being hinged with which to move down and pushed again
Position spring 323 so that 322 upper end of locking bar departs from the lock hole 3211 of lockplate 321, so that grain barrel-removing 1 is unlocked.Then,
Handlebar 311 is continued to rotate counterclockwise by driver, and stick swivel pin 317 is first upwards along the arcuate groove 3121 of rocking arm 312
Upper extreme position E is moved to, then stick swivel pin 317 is moved down with rocking arm 312, so as to promote hydraulicdirectional control valve stick
313 move down, and hydraulic inverting valve spindle 318 is moved down so that hydraulicdirectional control valve commutation, moves on to outside grain barrel-removing driving cylinder piston rod 21
Position, grain barrel-removing 1 rotate around it center and are clockwise to and skewed carry out unloading.Complete release handle after grain barrel-removing 1 is unlocked
Bar 311, handlebar 311 automatically return to neutral position, and hydraulic inverting valve spindle 318 also returns to the middle position of three position directional valve, now
Locking bar 322 stretches out locking bar support base 324 in the presence of back-moving spring 323.
Grain barrel-removing 1 is recovered to erectility and then locked operating process with 1 releasing process of aforementioned grain barrel-removing conversely, driving
Handlebar 311 is first pushed away to the right by the person of sailing, and 312 left end of rocking arm pulls hydraulicdirectional control valve stick 313 by stick swivel pin 317
Upper shifting, moves on hydraulic inverting valve spindle 318 and causes hydraulicdirectional control valve commutation, and grain barrel-removing drives cylinder piston rod 21 to retract in place,
Grain barrel-removing 1 rotates around it center and rotates counterclockwise reset.In the reseting procedure of grain barrel-removing 1, lockplate 321 first touches locking bar
Pushed when 322, then when 322 upper end of locking bar reaches 3211 position of lock hole of lockplate 321,323 reset force of spring
Under promotion, 322 upper end of locking bar is stretched in the lock hole 3211 of lockplate 321, so as to lock grain barrel-removing 1.
In addition to the implementation, the present invention can also have other embodiment, all employing equivalents or equivalent transformation shape
Into technical scheme, all fall within the protection domain of application claims.
