It should be noted that the conventional technical solutions adopted by those skilled in the art, such as directly arranging the buffer hopper 1 on the harvester frame, and other related technical solutions, all belong to the protection scope of the utility model.

[0028] The buffer blocking plate assembly 4 comprises a supporting arm 401, a blocking plate 402 and a stop rod 403. One end of the supporting arm 401 is rotatably connected around the buffer hopper 2, and the other end is fixed to the blocking plate 402 through bolts. The harvester frame 1 is provided with a stop rod 403 for limiting the movement of the blocking plate 402. The two sides of the buffer hopper 2 are also provided with a power assembly 404 for controlling the movement of the buffer blocking plate assembly 4. One end of the power assembly 404 is connected to the harvester frame 1, and the other end is connected to the supporting arm 401. By controlling the power assembly 404, the position of the blocking plate 402 can be flexibly adjusted, so as to control the falling of the stored material.

[0029] The embodiment is also provided with a ton bag hook assembly and a control linkage assembly 9 for controlling the opening of the ton bag hook assembly to take out the ton bag. The ton bag hook assembly is arranged below the harvester frame 1 and includes two sets of first ton bag fixed hooks 5 and two sets of second ton bag movable hooks 6. The first ton bag fixed hooks 5 are arranged at both sides of the rear end of the harvester frame 1, and the second ton bag movable hooks 6 are arranged at both sides of the front end of the harvester frame 1. The second ton bag movable hooks 6 are composed of a ton bag rope baffle 601 and a ton bag rope blocking bolt 602. The ton bag rope baffle 601 is arranged on the harvester frame 1, and the upper end of the ton bag rope blocking bolt 602 penetrates through the L-shaped structure of the harvester frame 1 and contacts the ton bag rope baffle 601. The upper end of the ton bag rope blocking bolt 602 can move up and down. When the ton bag rope blocking bolt 602 rises and contacts the ton bag rope baffle 601, the two will firmly fix the rope on the ton bag on the second ton bag movable hook 6. When the ton bag rope blocking bolt 602 descends, a gap is exposed between the ton bag rope blocking bolt 602 and the ton bag rope baffle 601, so that the ton bag rope can be conveniently and quickly taken off from the second ton bag movable hook 6.

The harvester tail is further provided with a limiting structure 904 for cooperating with the reset spring 903 to drive the ton bag rope blocking bolt 602 to reset. The pedal 902 drives the ton bag rope blocking bolt 602 to move up and down through the control soft shaft 901. The reset spring 903 is further arranged on the control soft shaft 901 and cooperates with the limiting structure 904 arranged on the harvester to drive the ton bag rope blocking bolt 602 to reset. The operator only needs to press the pedal 902 to release the ton bag rope hung on the second ton bag movable hook 6, which greatly improves the replacement speed of the ton bag.

[0031] Further, the buffer assembly 8 for slowing down the falling speed of the storage material is further arranged in the buffer hopper 2. In the embodiment, the buffer assembly 8 is a buffer plate, and a buffer belt can also be selected according to the actual situation. The buffer assembly 8 is fixed on the inner walls of both sides of the buffer hopper 2 through bolts. The design of the buffer assembly 8 can effectively slow down the falling speed of the storage material and prevent the storage material from being damaged or peeled due to direct impact of the material on the buffer hopper 2.

[0032] In the embodiment, an operation platform 7 is further arranged behind the harvester for facilitating the operator to stand and work, the operation platform 7 comprises a guard plate 701, a standing plate 702 and a connecting seat 703. The guard plate 701 is fixed to the rear side of the harvester through the connecting seat 703, and the standing plate 702 is fixed to the guard plate 701 through a hinge. The design of the operation platform 7 provides a safe and stable standing position for the operator, and facilitates the operator to replace the ton bag and other related operations.

[0033] In the embodiment, an L-shaped ton bag placing platform for driving the ton bag to move up and down is further arranged in the interval between the two operation platforms 7, the ton bag placing platform is fixed behind the harvester and is driven to move up and down by the oil cylinder arranged on the harvester, and the operation buttons for closing and opening the control buffer baffle assembly 4 are centrally arranged on the harvester frame 1 to facilitate the operator to operate.

[0034] Through the above structure design, the ton bag storage and discharge device can quickly replace the ton bag without stopping the machine, greatly improves the operation efficiency and continuity, reduces the interruption time in operation, and meets the demand of modern agricultural mechanization for high efficiency and continuous operation.

[0035] Working steps:

[0036] In the first step, the ton bag is hung on the ton bag hook assembly. The operator first fixes the front part of the ton bag on the first ton bag fixed hook, then steps on the pedal to control the ton bag rope blocking bolt of the second ton bag movable hook to move downward, so as to fix the hanging rope at the rear part of the ton bag on the second ton bag movable hook, and after the pedal is released, the ton bag rope blocking bolt is driven by the reset spring to fix the hanging rope at the rear part of the ton bag on the second ton bag movable hook.

[0037] In the second step, the harvester is started, and the harvested storage is sent into the buffer hopper through the conveying system. The material in the buffer hopper falls into the ton bag through the discharge port under the action of gravity. The operator monitors the ton bag filling condition.

[0038] In the third step, when the ton bag is about to be filled, the operator controls the closure of the buffer baffle assembly to temporarily close the discharge port and prevent the storage from continuing to fall into the ton bag, and the storage collected by the harvester is temporarily stored in the buffer hopper.

[0039] In the fourth step, the operator steps on the pedal on the operation platform to control the ton bag rope blocking bolt to move downward through the control of the flexible shaft, releases the ton bag rope on the second ton bag movable hook, and makes the filled ton bag smoothly separate from the hook structure.

[0040] In the fifth step, the filled ton bag is removed and a new empty ton bag is hung. The first step is repeated, the new ton bag is fixed on the ton bag hook assembly, and then the control of the buffer barrier assembly is performed to reopen the discharge opening. The material stored in the buffer hopper is quickly dropped into the new ton bag under the action of gravity, and the cycle continues.

[0041] It should be noted that although the utility model has been described through the above embodiments, the utility model can also have other various embodiments. Without departing from the spirit and scope of the utility model, those skilled in the art can obviously make various corresponding changes and modifications to the utility model, but these changes and modifications should all belong to the scope protected by the claims and equivalents of the utility model.
