Further preferably, set in the release mechanism on spring, spring suit gag lever post, spring makes gag lever post nature
It is lower to stretch out.
Further preferably, during normal operating condition, the gag lever post of release mechanism blocks lower rotation support outer, during maintenance,
The gag lever post of release mechanism, which stretches out, stops lower rotary support opposite side.
Further preferably, the supporting surface of the lower shaft stool and lower rotary support tilts certain angle, such as 1 °, either
The supporting surface of the lower shaft stool and lower rotary support is in the shape of a spiral.
Further preferably, grain barrel-removing lower end connects tanker housing by changeover joint, and unloading cylinder support is arranged on transition
On interface, the lower end of unloading oil cylinder by bearing pin and unloading cylinder support, the oil cylinder guide rod upper end of unloading oil cylinder with grain barrel-removing
Axle be connected.
The beneficial effects of the utility model are：Tanker assembling is easy, and dismounting is easy, and tanker shell can be directly screwed out during maintenance
Body simultaneously makes it suitably raise, easy to maintenance to mitigate complete machine gross weight, carries cross-country traveling ability, and improve unloading oil cylinder
Working method, improves the service life of unloading oil cylinder.

Embodiment
The utility model is further clarified below in conjunction with the accompanying drawings.
Referring to Figures 1 and 2, a kind of grain box of harvester closing device, including upper rotary support 1, upper axle suspension arm bearing 3, under
Shaft stool, lower rotary support 11, release mechanism 10, as shown in figure 4, described upper one end of axle suspension arm bearing 3 passes through bolt and threshing
Frame 2 is connected, and the upper other end of axle suspension arm bearing 3 is provided with upper axle, and upper rotary support 1 is connected by bolt with tanker housing 6,
Then the axis hole of upper rotary support 1 coordinates with the upper axle of upper axle suspension arm bearing 3, and the lower shaft stool is fixed on chassis 9, described
Lower shaft stool is provided with lower axle, and the lower rotary support 11 is fixed on the bottom of tanker housing 6, lower axle and the axis hole 12 of lower rotary support
Coordinate, the lower axle and upper axle are coaxial；As shown in figure 5, the release mechanism 10 is arranged on chassis 9, the release mechanism 10
Gag lever post stop lower rotary support when stretching out.Set in the release mechanism 10 on spring, spring suit gag lever post, spring makes limit
Stretched out under the bar nature of position, pull gag lever post, gag lever post extrusion spring simultaneously shrinks.During normal operating condition, release mechanism 10
Gag lever post block lower rotation support outer, prevent tanker housing 6 from rocking, during maintenance, shrink gag lever post, then make tanker shell
Body 6 rotates around upper axle and lower axle, when being rotated in place, and the gag lever post of release mechanism 10, which stretches out, stops lower rotary support opposite side, prevents
Only tanker housing 6 circles round.
More particularly, the supporting surface of the lower shaft stool and lower rotary support tilts certain angle, such as 1 °, either
The supporting surface of the lower shaft stool and lower rotary support in the shape of a spiral, so in tanker folding：Upper axle ensures that tanker housing 6 revolves
Turn center, lower shaft stool determines the height and position of tanker housing 6, when tanker is opened, and increases with tanker housing open angle, tanker shell
The bottom surface of body 6 also increases with the gap of chassis 9, during to defined position, and gap reaches maximum, so more convenient maintenance.
Further, as shown in figure 4, the lower end of grain barrel-removing 4 connects tanker housing 6, unloading cylinder support by changeover joint 8
7 are arranged on changeover joint 8, and the lower end of unloading oil cylinder 5 passes through bearing pin and unloading cylinder support 7, the oil cylinder guide rod of unloading oil cylinder 5
Upper end is connected with the axle on grain barrel-removing 4.During unloading, hydraulic oil ejects oil cylinder guide rod into unloading oil cylinder 5, makes grain barrel-removing
4 rotate to the right, reach that specified location stops, during return, hydraulic oil outflow unloading oil cylinder 5, inside oil cylinder guide rod retract cylinder.
Special changeover joint 8 is fixedly connected by bolt with tanker housing 6, and the lower end of grain barrel-removing 4 passes through flange and transition
Interface 8 is rotatably connected.
Above-mentioned embodiment is not restricted embodiment of the present utility model, and all those skilled in the art are in this reality
With the modification or equivalent deformation carried out on the basis of new substantive content, protection domain of the present utility model it
