[0034] The corn ear box 1 of the present invention can ensure that the corn ears in the corn ear box 1 are dumped evenly and quickly by setting the peristaltic wall, and there is no need to design a triangular protruding structure, thereby solving the problems existing in the existing grain harvester.

[0035] To further optimize the solution, in order to avoid the setting of the driving arm 3 affecting the extension and retraction of the supporting frame and to ensure the structural stability of the supporting frame, the supporting frame includes two parallel vertical slots 4, the vertical slot 4 is a U-shaped structure, and the notches of the two vertical slots 4 are arranged opposite to each other; the two vertical slots 4 are slidingly provided with mounting rods 5, and the outside of the vertical slots 4 is fixedly connected with a telescopic cylinder 6, and the output end of the telescopic cylinder 6 is connected to the top of the mounting rod 5; a connecting structure 7 is provided between the two vertical slots 4 and between the two mounting rods 5; the fruit ear box 1 is provided between the two mounting rods 5, and the fruit ear box 1 is rotatably connected to the top of the mounting rod 5, and the driving arm 3 is installed on the connecting structure 7 between the two mounting rods 5.

[0036] According to a further optimized solution, a rotating shaft 8 is fixedly connected between the two mounting rods 5 , and the ear box 1 rotates in conjunction with the mounting rods 5 via the rotating shaft 8 .

[0037] To further optimize the solution and improve the overall stability of the device, the support frame also includes a diagonal brace 9, the top end of the diagonal brace 9 is connected to the top of the vertical groove 4, and the bottom end of the diagonal brace 9 is used to connect to the walking device.

[0038] According to a further optimization scheme, in order to support the fruit ear box 1 and reduce the stress on the rotating shaft 8 , a support frame 10 is fixedly connected to an oblique support 9 , and the support frame 10 is used to support the fruit ear box 1 .

[0039] A further optimization scheme is adopted to achieve periodic vibration of the peristaltic plate 2 to facilitate the rapid dumping of corn ears in the ear box 1. The driving assembly includes a motor 11. A plurality of crankshafts 12 are rotatably connected to the ear box 1. The motor 11 is coordinated with a crankshaft 12 for transmission. The plurality of cranks on the crankshaft 12 are staggered, and two adjacent peristaltic plates 2 are respectively connected to two adjacent cranks on the crankshaft 12 for limited rotation.

[0040] According to a further optimization scheme, a sprocket 13 is fixedly connected to the output shaft of the motor 11, and a sprocket 2 14 is fixedly connected to one end of the crankshaft 12. The sprocket 13 and the sprocket 2 14 are matched through a chain transmission.

[0044] The peristaltic corn ear dumping device provided by the present invention has the following working principles:

[0045] The corn box 1 is mounted on a walking device via a supporting frame to facilitate the movement of the corn box 1. During use, the length of the mounting rod 5 extending out of the vertical slot 4 is adjusted by the telescopic cylinder 6 according to the use requirements, thereby adjusting the height position of the corn box 1. Since the vertical slot 4 is a U-shaped structure, the setting of the connecting structure 7 can be prevented from affecting the relative position between the mounting rod 5 and the vertical slot 4. When the corn box 1 needs to dump the corn ears inside, the driving arm 3 is controlled to extend, and the driving arm 3 is used to rotate the corn box 1 around the rotating shaft 8, thereby realizing the flipping of the corn box 1. At the same time, the motor 11 is started, and the crankshaft 12 is driven by the motor 11 to rotate. The crank on the crankshaft 12 is used to make the peristaltic plate 2 vibrate up and down periodically, so that the corn ears in the corn box 1 can be quickly dumped.
