[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.
[0041] like Figures 1 to 8 As shown, the utility model discloses a rotary traction device, which includes a gear box 1, a traction connection frame 2, a swing traction frame 3, and a transmission shaft assembly 4. The gear box 1 is connected to the forming chamber of the baler for providing power to the baler. In the embodiment of the utility model, the forming chamber and the pick-up feeding assembly are driven by the gear box 1 to provide power to the baler. The traction connection frame 2 is connected to both sides of the gear box 1 and is rotatably arranged in the radial direction of the gear box 1. Figure 1As shown in , the radial direction of the gearbox 1 here refers to the vertical rotation so as to adjust the connection angle between the traction connecting frame 2 and the gearbox 1. The swing traction frame 3 is connected to the traction connecting frame 2 and can be rotated in the horizontal direction; by setting the swing traction frame 3, the angle adjustment when the tractor turns can be achieved; the transmission shaft assembly 4 includes a front transmission shaft 41 connected to the gearbox 1 and a rear transmission shaft 42 connected to the tractor power; the swing traction frame 3 is connected to the tractor suspension, and a universal joint assembly 31 is provided in the swing traction frame 3, one end of the universal joint assembly 31 is connected to the front transmission shaft 41, and the other end is connected to the rear transmission shaft 42. As shown in Figure 1 As shown in the figure, by dividing the transmission shaft assembly 4 into a front transmission shaft 41 and a rear transmission shaft 42, and cooperating with the rotatable setting of the swing traction frame 3, when the tractor turns, the angle of the swing traction frame 3 changes, and no damage is caused to the shaft. In addition, since the swing traction frame 3 is connected to the tractor suspension, when the tractor pulls the baler to work and encounters a ridge, the driver can raise the baler's crossing height by raising the tractor suspension, thereby improving the baler's passability.
[0042] In the above embodiment, by dividing a whole transmission shaft into a front transmission shaft 41 connected to the gear box 1 and a rear transmission shaft 42 connected to the tractor, and by setting a universal joint assembly 31 in the swing traction frame 3, the swing traction frame 3 can be adjusted in the horizontal direction. Compared with the prior art, it not only avoids damage to the rotating shaft when turning, but also improves the passability, and does not increase the gear box 1, thereby reducing the cost.
[0043] Alternatively, if Figure 2 As shown in the figure, the swing traction frame 3 includes a fixed frame 32 and a swing frame 33. The swing frame 33 and the fixed frame 32 are arranged opposite to each other, and the swing frame 33 is rotatably connected to the fixed frame 32, and the rotation axes of the two are in the vertical direction. In the embodiment of the utility model, the universal joint assembly 31 is arranged inside the fixed frame 32 and the swing frame 33, and the position of the universal joint assembly 31 corresponds to the position of the rotation axis of the fixed frame 32 and the swing frame 33, so as to realize the synchronous rotation with the universal joint assembly 31 and the swing frame 33.
[0044] Alternatively, if Figure 2 and Figure 3 As shown in the figure, the swing frame 33 also has two limit plates 331 arranged obliquely and symmetrically on both sides in the horizontal direction, and the limit plates 331 are used to limit the swing angle of the swing frame 33. When the swing angle of the swing frame 33 is too large, the limit plates 331 will contact the fixed frame 32, thereby limiting the rotation angle between the swing frame 33 and the fixed frame 32 from being too large to cause damage to the universal joint assembly 31.
[0045] Alternatively, if Figures 2 to 4As shown in the figure, the swing traction frame 3 also includes a traction bracket 34, which is rotatably connected to the side of the swing frame 33 away from the fixed frame 32, and the rotation axes of the traction bracket 34 and the swing frame 33 are arranged horizontally. Through the rotatable connection of the traction bracket 34, the traction bracket 34 can swing up and down to adapt to the unevenness of the field land. Of course, it should be pointed out here that there are many structural forms of rotational connection, for example, the rotational connection can be achieved by a connecting shaft and a connecting sleeve arranged on the traction bracket 34. In the embodiment of the utility model, an oil filling port can also be arranged on the connecting shaft, and the oil filling port is connected to the oil channel in the connecting shaft. This arrangement can improve lubricity. In addition, in the embodiment of the utility model, the two ends of the traction bracket 34 can be connected to the tractor suspension through a pin shaft. Specifically, the connection part of the traction bracket 34 includes a fixed plate, a connecting shaft and a positioning shaft. The setting of the positioning shaft can avoid the pin from falling and improve the connection reliability.
[0046] Alternatively, if Figure 4 and Figure 5 As shown in the figure, the swing frame 33 also has a limit frame for limiting the rotation angle of the traction bracket 34. Specifically, the limit frame includes a limit support plate 332 extending toward the traction bracket 34 and located at the upper and lower sides of the traction bracket 34, and also includes a baffle plate 333 connected to the two limit support plates 332 at both ends. In this way, the two limit support plates 332, the baffle plate 333 and the swing frame 33 form a limit space for the traction bracket 34 to rotate, thereby avoiding the risk of rollover caused by excessive rotation angle of the limit bracket.
[0047] Alternatively, if Figure 6 As shown in , the two limiting support plates 332 are arranged opposite to each other, and each has two limiting surfaces 3321 with a set angle. That is, when the traction bracket 34 rotates to a certain angle, it contacts one of the limiting surfaces 3321, blocking the further rotation of the traction bracket 34.
[0048] Alternatively, if Figure 7 As shown in FIG, flexible plates 35 are connected to both sides of the fixed frame 32 and the swing frame 33. The flexible plate 35 here can be a plate made of rubber material. Through the setting of the flexible plate 35, a protective effect can be played to prevent foreign objects from entering the universal joint assembly 31 when the baler turns.
[0049] Optionally Figure 1 and Figure 8As shown in the figure, both ends of the front transmission shaft 41 and the rear transmission shaft 42 are provided with a cross-axis connector 411, and the end of the rear transmission shaft 42 connected to the tractor is also provided with a clutch 421. Through the provision of the cross-axis connector 411, a certain angle change is allowed between the front transmission shaft 41 and the rear transmission shaft 42, so as to better protect the transmission mechanism; through the provision of the clutch 421, when the baler is stuck or the like, the clutch 421 will be disconnected, which plays a role of overload protection and avoids damage to the tractor.
[0050] In an embodiment of the utility model, a baler is also provided, comprising any one of the above-mentioned rotary traction devices.
[0051] Application scenario of an exemplary embodiment:
[0052] like Figures 1 to 8 As shown, during the specific assembly, the gear box 1 is connected to the molding chamber and the picking and feeding assembly, the other side of the gear box 1 is connected to the traction connecting frame 2, the traction connecting frame 2 is connected to the fixed frame 32, the fixed frame 32 is connected to the swing frame 33, the swing frame 33 is rotatably connected to the traction bracket 34, the traction bracket 34 is connected to the suspension of the tractor, and then the front transmission shaft 41 is set in the middle of the traction connecting frame 2, and the two ends are respectively connected to the gear box 1 and the universal joint assembly 31 in the swing traction frame 3, and one end of the rear transmission shaft 42 is connected to the universal joint assembly 3 1, and the other end of the rear drive shaft 42 is connected to the tractor; when performing field operations, when the ground is uneven, due to the rotatable setting of the traction bracket 34, the traction bracket 34 can swing up and down in the width direction, thereby improving the adaptability to the ground; in addition, due to the split setting of the transmission shaft assembly 4 and the connection of the swing traction frame 3 with the universal joint assembly 31, the turning flexibility can be improved; in addition, through the setting of the limit plate 331 and the limit frame, damage caused by excessive rotation can also be avoided.
