[0035] As Figure 1 - Figure 13As shown, the top wall of each upper support plate 5 is fixedly connected with a rotating shaft counterbore 14 on both sides, and every three rotating shaft counterbores 14 are provided with a connecting shaft 22 inside. The three rotating shaft counterbores 14, the three first shaft sleeves 18 and the three second shaft sleeves 20 are connected through the connecting shaft 22, so that the left walkway plate 19 and the right walkway plate 21 can be conveniently rotated. The left walkway plate 19 is arranged on the left side of the top of each upper support plate 5, and the first shaft sleeve 18 is fixedly connected to the right side wall of each left walkway plate 19. The three first shaft sleeves 18 and the three left rotating shaft counterbores 14 are cross-connected, so that the connecting shaft 22 can enter the inside of the first shaft sleeve 18 and the rotating shaft counterbore 14 to connect the first shaft sleeve 18 and the rotating shaft counterbore 14.

The left side wall of each left walkway plate 19 and the right side wall of each right walkway plate 21 are threadedly connected with a hinge 31. When the left walkway plate 19 and the right walkway plate 21 are rotated, the hinge 31 prevents excessive rotation and facilitates folding of the left walkway plate 19 and the right walkway plate 21, so as to facilitate storage and arrangement of the grain at the bottom of the walkway plate.

[0036] As Figure 1 - Figure 13As shown, the top wall of the first fixed plate 1 is fixedly connected with a support block 23, the left side wall of the support block 23 is provided with a motor 24, the support block 23 is fixed on the top of the first fixed plate 1, the motor 24 is supported and fixed, the output end of the motor 24 is fixedly connected with a rotating shaft 25, the bottom end of the rotating shaft 25 is fixedly connected with a first rotating wheel 26, the rotating shaft 25 on the output end of the motor 24 is connected with the first rotating wheel 26, and the first rotating wheel 26 is driven to rotate, the inside of the first rotating wheel 26 is rotatably connected with a belt 27, the right side wall of the second fixed plate 2 is fixedly connected with a semicircular plate 28, the inside of the semicircular plate 28 is rotatably connected with a second rotating wheel 29, the right end of the belt 27 is rotatably connected in the inside of the second rotating wheel 29, when the belt 27 is driven to rotate by the first rotating wheel 26, the right end of the belt 27 is arranged in the inside of the second rotating wheel 29, and the second rotating wheel 29 is fixed on the right side wall of the second fixed plate 2 through the upper and lower semicircular plates 28, so as to support the belt 27 and enable the belt 27 to stably rotate, the outside of the belt 27 is connected in the inside of the upper support plate 5 and the lower support plate 7, the front and rear two hole grooves of the right single upper support plate 5 and the lower support plate 7 are fixedly connected with a fixed ring 30, the inside of the two fixed rings 30 is fixedly connected with the outside of the belt 27, when the belt 27 rotates, the fixed ring 30 on the belt 27 is fixed in the hole groove of the rightmost upper support plate 5 and the lower support plate 7, so as to drive the upper support plate 5 and the lower support plate 7 to stretch and expand, and the left walkway plate 19 and the right walkway plate 21 are connected with each other, so that the rightmost one can drive all to stretch and fold.

[0037] It should be noted that the utility model is a folding telescopic grain walkway plate, first, 24 is connected with the external power supply and the control end, and the device is powered and controlled.

[0038] In the unfolded state, the first fixed plate 1 and the second fixed plate 2 serve as the two side support structures of the walkway plate. The support plate 3 is fixed to the inner side walls of the first fixed plate 1 and the second fixed plate 2 through the first clamping block 4, providing stable horizontal support for the overall structure. The upper support plate 5 and the lower support plate 7 are connected by the buckle 6 and the second clamping block 12 in the shell 8.

[0039] The supporting rod 9 inside the shell 8 pushes the second clamping block 12 out of the placing groove 13 under the action of the spring 11, so that the second clamping block 12 is clamped in the hole groove of the buckle 6. In this way, the upper supporting plate 5 and the lower supporting plate 7 are connected together to form a stable supporting surface. At the same time, the stud bolt rod 15 and the supporting rod 17 play a connecting and reinforcing role. The stud bolt rod 15 connects the first fixed plate 1 with the upper supporting plate 5 and the lower supporting plate 7 on the left side, and the threaded rod 16 and the supporting rod 17 connect the upper supporting plate 5 and the lower supporting plate 7 on the right side and the second fixed plate 2 together, so as to ensure that the entire walkway plate has sufficient strength and stability in the unfolded state.

[0040] When it is necessary to disassemble the walkway plate, the second clamping block 12 is pressed to generate extrusion, and the extrusion force is transmitted to the supporting rod 9. The supporting rod 9 slides into the shell 8 against the elastic force of the spring 11, so that the second clamping block 12 is separated from the hole groove of the buckle 6. At this time, the connection between the upper supporting plate 5 and the lower supporting plate 7 is released, and the walkway plate can be disassembled. The connection between the first fixed plate 1 and the second fixed plate 2 can be achieved by adjusting the stud bolt rod 15 and the threaded rod 16. The stud bolt rod 15 and the threaded rod 16 can be disassembled or their lengths can be adjusted, so that the entire walkway plate occupies less space, facilitating storage and transportation, thereby achieving the effect of quick installation and disassembly.

[0041] When the walkway plate is needed, the left walkway plate 19 and the right walkway plate 21 are in a horizontal state to provide a walking plane for the staff. The hinge 31 can play a connecting and auxiliary rotating role when folding. In the transmission part, the motor 24 drives the rotating shaft 25 to rotate after being started, so that the first rotating wheel 26 at the bottom end of the rotating shaft 25 rotates. The first rotating wheel 26 drives the second rotating wheel 29 to rotate through the belt 27. The belt 27 penetrates the upper supporting plate 5 and the lower supporting plate 7 and is connected and fixed with the single upper supporting plate 5 and the lower supporting plate 7 on the right through the fixing ring 30.

[0042] When the motor 24 operates, the belt 27 rotates circularly under the drive of the first rotating wheel 26 and the second rotating wheel 29. Due to the fixing effect of the fixing ring 30, the upper supporting plate 5 and the lower supporting plate 7 on the right side move with the movement of the belt 27. This movement can realize the stretching and contracting function of the walkway plate. When it is necessary to lengthen the walkway plate, the motor 24 rotates forward, and the belt 27 drives the right structure to move to the right side, so as to lengthen the walkway plate. When it is necessary to shorten the walkway plate, the motor 24 reverses, and the belt 27 drives the right structure to move to the left side, so as to realize the contraction of the walkway plate.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
