[0027] Modern harvesting machinery rarely has an extended unloading mechanism. Among the known extended unloading mechanisms in harvesting machinery, the mechanism is opened and closed by flipping an arc-shaped sliding groove. However, when the box is not flipped, the existing mechanism is located above the box, which will cover part of the box opening and reduce the area of ​​the grain inlet, which can easily cause grain loss. It will also increase the overall height of the box, making it impossible to avoid height restriction issues during transportation.

[0028] The design feature of this utility model is that it adopts a non-folding structure where the extension mechanism is always on the side, which does not obstruct the grain inlet area. Grain can be unloaded when the distance between the harvester and the trailer (grain receiving vehicle) is within 60cm, which greatly speeds up the unloading efficiency and reduces safety hazards.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Extension plate 4 is slidably disposed at the discharge end of box body 8;

[0034] The buffer section is located at the bottom of the housing 8.

[0035] In use, the extension plate 4 is slidably set at the discharge end of the box 8. When filling, the opening of the box 8 faces upward, and the extension plate 4 naturally retracts to below the opening of the box 8 under the action of gravity. It will not block the opening of the box 8, nor will it exceed the height of the box 8 itself. When it is necessary to dump the grain, the box 8 is overturned, and the extension plate 4 naturally slides out under the action of gravity. Grain can be unloaded when the distance between the harvester and the trailer (grain receiving vehicle) is within 60cm, avoiding repeated adjustments of the vehicle distance, greatly speeding up the unloading efficiency and reducing safety hazards.

[0036] As an optional implementation, extension plate connectors 2 are fixedly connected to both ends of extension plate 4, and extension plate connectors 2 are slidably disposed in slide rail 1, which is fixedly connected to box 8.

[0039] As an optional implementation, an axle 3 is fixedly arranged in the extension plate connecting piece 2, and a pulley 5 is rotatably connected with the axle 3, and the pulley 5 rotates in the slide 1.

[0040] The axle 3 is arranged in the extension plate connecting piece 2, and the axle 3 can be arranged in plurality and is fixedly arranged in the extension plate connecting piece 2 by welding, and the pulley 5 is rotatably connected with the axle 3, and the extension plate connecting piece 2 rotates in the slide 1 through the pulley 5 to realize the relative sliding with the slide 1.

[0041] The sliding groove 6 is formed in the side wall of the slide 1, and the locking sliding block 7 is slidably arranged in the sliding groove 6, and the locking sliding block 7 is fixedly connected with the tail end of the extension plate connecting piece 2 in the extension direction, so that the slide 1 and the extension plate connecting piece 2 are prevented from slipping off.

[0042] As an optional implementation, the buffer part comprises an air cushion 9, and the air cushion 9 is fixedly arranged on the inner wall of the bottom of the box body 8.

[0043] The air cushion 9 is arranged on the bottom of the box body 8, so that the grain is prevented from being damaged due to the steel contact collision when falling from a high place, and economic waste is avoided, and the loss rate can be obviously reduced after the air cushion 9 is arranged.

[0044] As an optional implementation, the extension plate 4 and the extension plate connecting piece 2 are fixedly connected through bolts.
