[0001] The utility model belongs to the field of threshing equipment, and particularly relates to a conveying cross-bridge with a feeding mechanism and a harvester. Background Art

[0002] The harvester includes a cutting table, a conveying cross-bridge and a threshing cylinder. When harvesting crops, the material passes from the cutting table through the conveying cross-bridge and enters the threshing cylinder. The material is gradually conveyed into the threshing cylinder by the throwing of the conveying cross-bridge. In the case of a sudden increase in the amount of material, the throwing capacity at the end of the conveying cross-bridge is weak, and part of the material cannot enter the threshing cylinder completely, and will accumulate at the front end of the threshing cylinder. As the accumulation time is longer, there are more obstacles, and the subsequent material is blocked from entering, resulting in blockage at the end of the conveying cross-bridge, which not only affects the operation efficiency of the whole machine, but also causes damage to the components of the conveying cross-bridge due to blockage.

[0003] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] This embodiment provides a conveying overbridge with a feeding mechanism, as Figure 1 shown, including a conveying overbridge 10 and further including a feeding mechanism 20. The rear end of the conveying overbridge 10 is used to connect to a threshing cylinder 30. The feeding mechanism 20 is disposed at the rear end of the conveying overbridge 10, and the feeding mechanism 20 is used to convey the materials at the rear end of the conveying overbridge 10 into the threshing cylinder 30.

[0029] Further, in some embodiments, as Figure 2 、 Figure 3 shown, the feeding mechanism 20 includes a feeding roller 21, and the feeding roller 21 is disposed at the rear end of the conveying overbridge 10.

[0030] Further, in some embodiments, as Figure 3 、 Figure 4 shown, the feeding roller 21 includes a rotating roller 211 and a stirring plate 212, and the stirring plate 212 is disposed on the rotating roller 211.

[0031] Further, in some embodiments, as Figure 4As shown, the feeding roller 21 further includes a V-shaped plate 213. The rotating roller 211 is connected to the V-shaped plate 213, and the V-shaped plate 213 is connected to the stirring plate 212. Such a structure is convenient for connecting the stirring plate 212 on the one hand and facilitating the replacement of the stirring plate 212 when it is damaged; moreover, using the V-shaped plate 213 not only has better stability and strength; and using the V-shaped plate 213 is convenient for controlling the connection angle of the stirring plate 212. By setting the lengths of both ends of the V-shaped plate 213, the angle of the stirring plate 212 can be controlled. The stirring plate 212 with a specific angle has a better feeding effect; it should be noted that the installation angle of the stirring plate 212 in the present utility model is not limited.

[0032] Further, in some embodiments, the stirring plate 212 is fixed to the V-shaped plate 213 by bolts. In this way, the stirring plate 212 has higher installation efficiency and replacement efficiency.

[0033] Further, in some embodiments, as Figure 4 shown, a plurality of V-shaped plates 213 are provided. The plurality of V-shaped plates 213 are evenly arranged around the rotating rod. Two stirring plates 212 are connected to one V-shaped plate 213, and a gap is provided between the two stirring plates 212.

[0034] Further, in some embodiments, as Figure 4 shown, six V-shaped plates 213 are provided.

[0035] Further, in some embodiments, as Figure 4 shown, the end of the stirring plate 212 away from the rotating roller 211 is provided with a toothed structure. The stirring plate 212 with a toothed structure can cut off the material entering the threshing cylinder 30 on the one hand, so as not to cause the sudden load pressure of the threshing cylinder 30 due to too large material, and has the advantages of improving the threshing efficiency of the threshing cylinder 30 and extending the service life of the threshing cylinder 30; in addition, it can also grab the material without loss, and has the advantage of improving the feeding efficiency.

[0036] Further, in some embodiments, as Figure 2 、 Figure 3 shown, the feeding mechanism 20 further includes a closed cover plate 22. The closed cover plate 22 is arranged above the feeding roller 21.

[0037] As Figure 3 shown, the sealing cover plate is fixedly connected to the threshing cylinder 30 by bolts.

[0038] Further, in some embodiments, as Figure 2 、 Figure 3As shown, the feeding mechanism 20 further includes a transmission component 23 and a connecting frame 24. The transmission component 23 is connected to the feeding roller 21, and the rotation of the transmission component 23 drives the rotation of the feeding roller 21. The connecting frame 24 is used to support the feeding roller 21. By providing the connecting frame 24, the feeding roller 21 can be directly installed on the basis of the existing harvester through the connecting frame 24, which has the advantage of reducing costs.

[0039] Preferably, the transmission component 23 is driven by the walking engine of the harvester. The engine drives the driving component to rotate through step-by-step transmission of an intermediate transition shaft. The specific connection structure will not be described in detail here. For those skilled in the art, this connection structure is known. Driving through the engine has the advantage of cost savings. Of course, the transmission component 23 or the feeding roller 21 can also be directly driven by an electric motor.

[0040] This embodiment also provides a harvester, as Figure 2 、 Figure 3 shown, including a threshing cylinder 30 and the above-mentioned conveying cross-bridge 10. The rear end of the conveying cross-bridge 10 is connected to the threshing cylinder 30, and the feeding mechanism 20 is arranged at the front end of the threshing cylinder 30.

[0041] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows mutual communication; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of multiple components or the interaction relationship of multiple components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
