[0034] Such as Figure 1 、 Figure 2As shown in the figure, the present utility model discloses a connecting arm, which includes a first connecting sub-arm 1, a second connecting sub-arm 2, a first connecting rod 31, and a second connecting rod 32. The first connecting sub-arm 1 and the second connecting sub-arm 2 are connected by the first connecting rod 31 and the second connecting rod 32. The second connecting sub-arm 2 and the first connecting sub-arm 1 are symmetrical structures to each other. Therefore, the structure of the first connecting sub-arm 1 will be taken as an example for introduction hereinafter. The first connecting sub-arm 1 is an integrally formed structure, and the first connecting sub-arm 1 includes a vertical section 11, an inclined section 12, and a horizontal section 13. The vertical section 11, the inclined section 12, and the horizontal section 13 are connected end to end in sequence from bottom to top. An included angle a is formed between the vertical section 11 and the inclined section 12 of the first connecting sub-arm 1, and the value range of the included angle a is 140° to 155°. The horizontal section 13 of the first connecting sub-arm 1 is perpendicularly arranged with respect to the vertical section 11 of the first connecting sub-arm 1. The connection between the vertical section 11 and the inclined section 12 adopts an arc design, and the connection between the inclined section 12 and the horizontal section 13 adopts an arc design, which can increase the bending resistance of the connecting arm. Such a setting enables the side surface of the connecting arm to be in the shape of a corner sickle as shown in Figure 2 shown. Such a connecting arm structure has higher strength to meet the requirement of supporting the rotation of the front bin bracket. Optionally, in the first connecting sub-arm 1, a rotating support 14 is further provided at one end of the horizontal section 13 away from the inclined section 12. The rotating support 14 is used to install the front bin frame of the round baler and realizes the rotational connection between the front bin frame and the connecting arm. One end of the first connecting rod 31 is welded to the connection between the inclined section 12 and the horizontal section 13 of the first connecting sub-arm 1, and the other end of the first connecting rod 31 is welded to the connection between the inclined section 12 and the horizontal section 13 of the second connecting sub-arm 2. One end of the second connecting rod 32 is welded to the vertical section 11 of the first connecting sub-arm 1 and is located at one end away from the inclined section 12 of the first connecting sub-arm 1; the other end of the second connecting rod 32 is welded to the vertical section 11 of the second connecting sub-arm 2 and is located at one end away from the inclined section 12 of the second connecting sub-arm 2.

[0035] Optionally, as shown in Figure 1 shown, the connecting arm further includes a reinforcing connecting rod 33. One end of the reinforcing connecting rod 33 is welded to the vertical section 11 of the first connecting sub-arm 1, and the other end of the reinforcing connecting rod 33 is welded to the vertical section 11 of the second connecting sub-arm 2. The reinforcing connecting rod 33 is located above the second connecting rod 32. Such a setting enables the overall structural stability of the connecting arm to be better.

[0036] Optionally, both the first connecting sub-arm 1 and the second connecting sub-arm 2 are made of alloy steel material and are in a plate structure, and the wall thickness of the first connecting sub-arm 1 and the second connecting sub-arm 2 ranges from 20 mm to 30 mm. For example, the alloy steel material can be Q355B type alloy steel material. By using alloy steel material to make the first connecting sub-arm 1 and the second connecting sub-arm 2 with a thickness of 20 mm to 30 mm and cooperating with the corner sickle-shaped structure, the structural strength and hardness of the connecting arm can be stronger.

[0037] Optionally, as Figure 1 , Figure 2 shown, a lifting lug 4 is further provided on the connecting arm, and the lifting lug 4 has a lifting hole 41, which is convenient for hoisting and avoids slipping. The number of lifting lugs 4 is two, and the two lifting lugs are respectively arranged on the first connecting sub-arm 1 and the second connecting sub-arm 2.
