[0023] The following further illustrates the technical solutions of the present utility model with reference to the accompanying drawings. Figures 1-7 A large square bale foot pedal folding structure is shown, including a foot pedal 1, a transition plate 2, a left mounting plate 3, a right mounting plate 4, a connecting piece 5, and a plug-in 6. A through hole is provided on the side wall of the right mounting plate 4 for the plug-in 6 to be inserted. A round hole 201 is provided on the right side wall of the transition plate 2. One end of the transition plate 2 is installed between the inner side walls of the left mounting plate 3 and the right mounting plate 4 through the connecting piece 5. When the transition plate 2 is flipped to be close to the bottom plates of the left mounting plate 3 and the right mounting plate 4, the round hole 201 is disposed opposite to the plug-in 6. One end of the foot pedal 1 is installed between the opposite inner side walls at the other end of the transition plate 2 through the connecting piece 5. The transition plate 1 serves as a medium. One end of it is connected to the mounting plate for installing the machine frame, and the other end is connected to the foot pedal. Since the foot pedal and the transition plate can be folded step by step into the position of the bottom plate of the mounting plate and locked and fixed by the plug-in, when performing maintenance and repair on the large square bale, pulling the plug-in can lower the foot pedal and the transition plate, and the maintenance personnel can step on it to perform maintenance on the machine. When no maintenance is required, such as Figure 6 andFigure 7 , the footrest and the transition plate are folded up, taking up no space and thus not affecting the operation of the machine.

[0024] As an embodiment of the present utility model, as Figure 5 , the plug-in 6 includes a bolt 601, a compression spring 602, a washer 603 and a fixing pin 604. One end of the bolt 601 passes through the side wall of the right mounting plate 4. When the transition plate 2 is flipped to be close to the bottom plate, one end of the bolt 601 is arranged opposite to the round hole 201. A pin hole, a washer 603 and a compression spring 602 are sequentially arranged on the other end of the bolt 601. The fixing pin 604 is inserted into the aforementioned pin hole, so that one end of the compression spring 602 abuts against the inner side wall of the mounting seat 7, and the outer shell of the mounting seat 7 is fixed to the outer side wall of the right mounting plate 4. After the transition plate 2 is flipped, pull one end of the bolt 601 to align it with the round hole 201, and then release the bolt 601. One end of it naturally inserts into the round hole 201 and will not fall out. At this time, the entire footrest assembly is folded and fixed, taking up no space, and the machine can operate normally.

[0025] As another embodiment of the present utility model, the plug-in 6 is designed as a fixing bolt. The rod portion of the fixing bolt passes through the side wall of the right mounting plate 4, and a through hole is provided at the passing position of the side wall. When the transition plate 2 is flipped to be close to the bottom plate, the rod portion of the fixing bolt is arranged opposite to the round hole 201, and threads are cooperatively provided on the inner walls of the through hole and the round hole 201. After the transition plate 2 is flipped, rotate the head of the fixing bolt to align and screw its screw rod portion into the round hole 201.

[0026] As Figure 4 , the connecting member 5 includes a bolt 501, a bushing 502, a nut 503 and two washers. The bushing 502 passes through the two adjacent side walls where it is located. The rod portion of the bolt 501 is arranged through the bushing 502. Washers and a nut 503 are sequentially arranged at the end of the bolt 501 that passes through the bushing 502. A washer is provided between the head of the bolt 501 and the bushing 502. The length of the bushing 502 is not less than the sum of the thicknesses of the two adjacent side walls where it is located, ensuring that the footrest 1 can be flipped and folded into the transition plate 2, and the transition plate 2 can be flipped and folded into the left mounting plate 3 and the right mounting plate 4.

[0027] As Figure 1 , a plurality of holes 8 are provided on the bottom plates of the left mounting plate 3 and the right mounting plate 4 to correspond and cooperate with the holes on the machine frame. The left mounting plate 3 and the right mounting plate 4 can be mounted on the machine frame according to the holes 8 through bolts or the like.

[0028] The working principle of the present utility model:

[0029] As Figures 1-7, when the maintenance is completed, first flip the footrest 1 and fold it into the transition plate 2, then pull the bolt 601, and then flip and fold the transition plate 2 into the left mounting plate 3 and the right mounting plate 4. Release the bolt 601, and at this time, one end of it naturally inserts into the round hole 201, completing the step-by-step folding of the footrest and the transition plate, saving space and not affecting the operation of the machine.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
