[0025] In this embodiment, the first U-shaped swing arm 24 is rotatably mounted on the front and rear outer side walls of the lower part of the first silo 11, and the middle part of the first U-shaped swing arm 24 is fixedly connected to the bottom of the first silo door 13. The second U-shaped swing arm 26 is rotatably mounted on the front and rear outer side walls of the lower part of the second silo 12, and the middle part of the second U-shaped swing arm 26 is fixedly connected to the bottom of the second silo door 14. For the convenience of installation, the front and rear outer side walls of the lower part of the first silo 11 can be fixedly mounted with a second hinge seat 113, and the upper parts of both ends of the first U-shaped swing arm 24 are respectively hinged to the corresponding second hinge seat 113, and the front and rear outer side walls of the lower part of the second silo 12 can be fixedly mounted with a third hinge seat 122, and the upper parts of both ends of the second U-shaped swing arm 26 are respectively hinged to the corresponding third hinge seat 122. In order to enhance the structural strength, a plurality of evenly distributed ribs 16 are fixedly connected between the middle of the first U-shaped swing arm 24 and the bottom of the first door 13 and between the middle of the second U-shaped swing arm 26 and the bottom of the second door 14 .
[0026] A third connecting rod 25 is hinged between the front and rear ends of the first U-shaped swing arm 24 and the second U-shaped swing arm 26, respectively. The hinge point F between the third connecting rod 25 and the first U-shaped swing arm 24 is higher than the hinge point G between the third connecting rod 25 and the second U-shaped swing arm 26. The third connecting rod 25 is preferably, but not limited to, a connecting rod with adjustable length, so as to facilitate the adjustment of the first U-shaped swing arm 24 and the second U-shaped swing arm 26 to synchronized swinging.
[0027] In this embodiment, the multi-link drive mechanism 2 includes a telescopic drive cylinder 21, a first link 21, and a second link 23. A first hinge seat 112 is fixedly provided on the outer side wall of the lower part of the first bin 11. The cylinder end of the telescopic drive cylinder 21 is hinged to the frame hinge seat 15, and the end of the movable rod of the telescopic drive cylinder 21 is hinged to the middle of the first link 21. The upper end of the first link 21 is hinged to the first hinge seat 112, the lower end of the first link 21 is hinged to one end of the second link 23, and the other end of the second link 23 is hinged to the middle of the first U-shaped swing arm 24. The hinge point D of the second link 23 and the first link 21 is higher than the hinge point E of the second link 23 and the first U-shaped swing arm 24. Among them, the telescopic drive cylinder 21 is preferably but not limited to a pneumatic cylinder, and of course, an oil cylinder or an electric cylinder can also be used; the first link 21 is preferably but not limited to a link with adjustable length.

The first U-shaped swing arm 24 and the second U-shaped swing arm 26 respectively drive the first bin door 13 and the second bin door 14 to rotate to open or close the first discharge port 111 and the second discharge port 121, realizing the opening and closing of the two bin doors in a limited space. For example, in the initial state, the telescopic drive cylinder 21 is in the extended state, and the first bin door 13 and the second bin door 14 are in the closed state; when it is necessary to open the first bin door 13 and the second bin door 14, the telescopic drive cylinder 21 starts to contract, and then the first bin door 13 and the second bin door 14 are opened; when it is necessary to close the first bin door 13 and the second bin door 14, the telescopic drive cylinder 21 starts to extend, and then the first bin door 13 and the second bin door 14 are closed. In this embodiment, the opening sizes of the first bin door 13 and the second bin door 14 can be changed by controlling the telescopic length of the telescopic drive cylinder 21 or adjusting the length of the second link 23.
