Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the present invention). Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0014] See also Figure 1-2 The utility model provides a technical solution: a box cover expansion structure for a harvester, comprising a box body 1, a cover plate Ⅰ2, a cover plate Ⅱ3, a side plate curtain Ⅰ4, a driving mechanism Ⅰ5, a rotating assembly 6, a rotating connecting rod 7, a driving mechanism Ⅱ8, a cover plate Ⅲ9, a cover plate Ⅳ10, and a side plate curtain Ⅱ11;

[0015] The driving mechanism I5 is installed on one side of the box body, and the output end of the driving mechanism I5 is connected to the rotating assembly 6. The rotating assembly 6 is arranged inside the box body 1. The outer side surface of the rotating assembly 6 is symmetrically hinged with two rotating connecting rods 7. The two rotating connecting rods 7 are respectively hingedly connected to the cover plate I2 and the cover plate II3. The driving mechanism I5 is extended or shortened to drive the rotating assembly 6 to rotate, thereby driving the cover plate I2 and the cover plate II3 to open and close relative to the box body 1 around the hinge;

[0016] The cover plate III9 is ​​connected to the cover plate I2 by a hinge; the cover plate IV10 is connected to the cover plate II3 by a hinge, and the two ends of a set of driving mechanisms II8 are respectively connected to the cover plate III9 and the cover plate I2, and the cover plate III9 can be opened and closed relative to the cover plate I2 around the hinge by extending or shortening the driving mechanism II8, and the two ends of another set of driving mechanisms II8 are respectively connected to the cover plate IV10 and the cover plate II3, and the cover plate IV10 can be opened and closed relative to the cover plate II3 around the hinge by extending or shortening the driving mechanism II8;

[0017] The two ends of the two sets of side panel curtains Ⅰ4 are respectively connected to the cover plate Ⅰ2 and the cover plate Ⅱ3. The side panel curtains Ⅰ4 are made of cloth material and have flexible unfolding and folding characteristics. They can be unfolded and folded by opening and closing the cover plates Ⅰ2 and Ⅱ3; the two ends of the side panel curtains Ⅱ11 are respectively connected to the cover plates Ⅲ9 and Ⅳ10. They are made of the same material as the side panel curtains Ⅰ4 and can be unfolded and folded by opening and closing the cover plates Ⅲ9 and Ⅳ10.

[0018] The driving mechanism I5 and the driving mechanism II8 may be hydraulic telescopic rods or electric telescopic rods, and the input ends of the driving mechanism I5 and the driving mechanism II8 are electrically connected to the output ends of the control switch located in the cab.

[0019] When in use: hierarchical control is performed according to the set opening and closing sequence. First, the drive mechanism Ⅰ5 control switch is turned on, and the drive mechanism Ⅰ5 is shortened to drive the rotating assembly 6 to rotate. The rotating assembly 6 drives the cover plate Ⅰ2 to rotate and unfold relative to the box body 1 around the hinge through two sets of rotating connecting rods 7, and the cover plate Ⅱ3 to rotate and unfold relative to the box body 1 around the hinge. The cover plates Ⅰ2 and Ⅱ3 are opened to drive the two sets of side plate curtains Ⅰ4 to unfold, that is, the first-level grain box cover is opened; then the drive mechanism Ⅱ8 control switch is turned on, and the cylinder rod of the drive mechanism Ⅱ8 is extended to drive the cover plate Ⅲ9 to unfold relative to the cover plate Ⅰ2 around the hinge, and the cover plate Ⅳ10 to unfold relative to the cover plate Ⅱ3 around the hinge. The cover plates Ⅲ9 and Ⅳ10 are opened to drive the two sets of side plate curtains Ⅱ11 to unfold, that is, the second-level grain box cover is opened, realizing the grain box volume expansion function. This is a box cover expansion and opening workflow.

[0020] When the operation is completed or the site is transferred, the grain box cover needs to be closed and folded. At this time, the drive mechanism Ⅱ8 control switch is first closed. The drive mechanism Ⅱ8 is shortened to drive the cover plate Ⅲ9 to fold around the hinge relative to the cover plate Ⅰ2, and the cover plate Ⅳ10 to fold around the hinge relative to the cover plate Ⅱ3. The folding of cover plates Ⅲ9 and Ⅳ10 drives the two sets of side panel curtains Ⅱ11 to fold, that is, the secondary grain box cover is folded; then the drive mechanism Ⅰ5 control switch is closed, and the cylinder rod of the drive mechanism Ⅰ5 is extended to drive the rotating component 6 to rotate. The rotating component 6 drives the cover plate Ⅰ2 to rotate and fold around the hinge relative to the box body 1, and the cover plate Ⅱ3 to rotate and fold around the hinge relative to the box body 1 through two sets of rotating connecting rods 7. The cover plates Ⅰ2 and Ⅱ3 are opened to drive the two sets of side panel curtains Ⅰ4 to fold, that is, the primary grain box cover is folded and closed. This is a box cover expansion, closing and folding workflow. The above two workflows constitute the entire grain box cover opening and closing function.

[0021] The utility model can maximize the volume of the grain box, reduce the number of grain unloading times, and increase the effective operating time of the harvester through the two-stage foldable box cover structure; folding during transfer can lower the passing height of the harvester, effectively improving the adaptability of the harvester; at the same time, the two-stage folding is both electronically controlled and can be adjusted with one button in the cab, which is convenient and quick to operate. Compared with the traditional manual mechanical operation of the box cover, it reduces the driver's work intensity and improves the control comfort.
