The grain bucket of claim 6 wherein the switch is rotatably coupled to the valve, the switch including a first engagement portion and a limit portion, the first engagement portion being engaged with the control mechanism when the switch is in the first position, the limit portion being in abutment with the valve, rotation of the switch from the first position to the second position being operable to disengage the limit portion from the valve.

8. A grain tank according to claim 3, wherein movement of the valve in a first direction opens/closes the respective grain outlet;

the control mechanism comprises a control piece movably connected with the supporting body, the barrel body can move relative to the supporting body to drive any valve to be matched with the control piece, and the control piece can move along the first direction to drive the valve matched with the control piece to move along the first direction, so that the corresponding grain outlet is opened/closed.

9. The grain tank of claim 8, wherein the valve is rotatably provided at the grain outlet, and wherein rotation of the valve in the first direction opens/closes the grain outlet; the control piece is rotationally connected with the supporting body, and the control piece can drive the valve matched with the control piece to rotate along the first direction so as to open/close the corresponding grain outlet.

10. The grain bucket of claim 8 or 9 wherein the control mechanism further comprises a second resilient member, the second resilient member being connected to both the control member and the carrier, the control member driving the valve to open the grain outlet causes resilient deformation of the second resilient member, and the return of deformation of the second resilient member causes the control member to allow the valve to close the grain outlet.

11. A grain bucket according to claim 3, wherein the control mechanism comprises a control member movably connected to the carrier and a handle connected to the control member;

the barrel body can drive any valve to be matched with the control piece when moving relative to the supporting body, and the handle is used for driving the control piece to move.

12. The grain bucket of claim 11, wherein the handle is connected to the control member via a flexible connection member, at least one reversing wheel is provided on the carrier, and the flexible connection member is wound around the reversing wheel.

13. The grain bucket of claim 11 wherein the carrier is provided with first and second coaxially fixed wheels, the first wheel having a smaller diameter than the second wheel, the handle and the first wheel being connected by a first connector, and the control and the second wheel being connected by a second connector.
