[0002] The bridge device is an important conveying component of equipment such as greenhouse stubble pullers, harvesters, and silage harvesters, and is mainly used for conveying crop stalks.

[0003] At present, the common conveying bridge components on the market are relatively similar in structure, including a bridge frame, a driving shaft assembly, a driven shaft assembly, a rake chain assembly. The motor drives the driving shaft to rotate, and the driving shaft and the driven shaft are driven by a rake chain. There are rake plates outside the rake chain to push the crop stalks. In the actual use process, there are some functional deficiencies and there is room for improvement. For example, the rotation of the rake plate depends on the transmission between the driving shaft and the driven shaft. During the rotation of the shaft rod, it is easy for the stalks to wind around the shaft or be caught in the gap between the bearing seat and the sprocket, causing the shaft rod to jam, thus forming a pile-up inside the equipment and increasing the probability of equipment damage. It does not have the function of preventing winding and jamming.

[0004] Now, a new type of anti-winding conveying bridge structure is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-winding conveying bridge structure to solve the problem of not having the function of preventing winding and jamming proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-winding conveying bridge structure, including a bridge frame.

A first ball bearing 3 is installed on one side of the first bearing seat 2 close to the overpass frame 1. A driving shaft 4 is horizontally installed between one sides of the two groups of first ball bearings 3. The left and right sides outside the driving shaft 4 are respectively fixedly connected with a first sprocket 5. A first stepped ring 6 is arranged on the side of the first ball bearing 3 close to the first sprocket 5. A driving tube 7 is sleeved between one sides of the two groups of first sprockets 5.

Among them, there is a stepped first stepped ring 6 between the first bearing housing 2 and the first sprocket 5, and there is a stepped second stepped ring 12 between the second bearing housing 8 and the second sprocket 11. This can prevent the crop stems from directly getting stuck in the gap between the shaft seat and the sprocket. The driving pipe 7 outside the driving shaft 4 and the driven pipe 13 outside the driven shaft 10 can prevent the stems or plastic ropes from directly winding around the driving shaft 4 and the driven shaft 10. The driving pipe 7 and the driven pipe 13 can slide directly, preventing the driving shaft 4 and the driven shaft 10 from being locked.
