By adopting the scheme of the invention, as the head end and the tail end of the bridging rod 12 are staggered by a preset angle, the bending amplitude of the bridging rod 12 is smaller, and when the threshing cylinder 1 rotates, the threshing teeth 13 on each bridging rod 12 are staggered to act on materials on the same bus of a material channel, so that the effect of dispersing the materials can be effectively achieved, the materials are prevented from being blocked, on one hand, the grass guide plate 31 can push the materials to move, on the other hand, the bridging rod 12 can also assist the materials, so that the materials can smoothly advance, the movement path of points on the bridging rod 12 is similar to the characteristics of the advancing path of the materials, and therefore, the obstruction of the materials on the threshing cylinder 1 is greatly reduced, and the energy consumption can be saved. In addition, as the bending amplitude of the bridging rod 12 is smaller, the included angle between the tangent line of the point on the bridging rod 12 and the central axis of the threshing cylinder 1 is small, the material is not easy to be firmly hung by the threshing teeth 13, and the material is easy to be separated even if being hung.
Preferably, the predetermined angle is 360 °/N, where N is the total number of jumper rods 12. In this embodiment, n=6, that is, a total of 6 bridging rods 12, and the predetermined angle is 60 °.
In particular, for easy installation, a plurality of fixing locations 11a are formed on each side plate 11, and the number of the fixing locations 11a is consistent with that of the bridging rods 12; two ends of each bridging rod 12 are respectively connected with two fixing positions 11a respectively belonging to two side plates 11, namely a first fixing position and a second fixing position, and the fixing positions 11a adjacent to the first fixing position and belonging to the same side plate 11 are oppositely arranged with the second fixing position.
Preferably, the bridging rod 12 is circular arc or spiral arc, when it is spiral arc, it is 1/N of a full turn spiral, where N is the total number of bridging rods 12. The spiral arc shape is adopted, so that the distance between each threshing tooth 13 on the bridging rod 12 and the central shaft of the threshing cylinder 1 is consistent. In this embodiment, the bridging rod 12 is in the shape of a spiral arc.
In the embodiment shown in fig. 2, the distribution of the threshing teeth 13 on each bridging rod 12 is the same, and the threshing teeth 13 on the bridging rods 12 are parallel to each other, in order to further improve the pushing effect on the material, in a preferred embodiment, as shown in fig. 3-4, the threshing teeth 13 on each bridging rod 12 are all equidistantly arranged according to a preset distance, the first threshing tooth 13 on the same end of each bridging rod 12 is set to be an initial threshing tooth a, each bridging rod 12 starts from the initial threshing tooth a, the following threshing teeth 13 are staggered by a preset angle relative to the preceding threshing teeth 13, and the staggering direction is the staggering direction of the other end of the bridging rod 12 relative to the end where the initial threshing tooth a is located, namely, the twisting direction of the bridging rod 12, which has the advantages that: when the roller rotates, not only the adjacent bridging rods 12 sequentially act on the materials, but also threshing teeth 13 on the same bridging rod 12 sequentially act on the materials, so that the continuity of the threshing teeth 13 acting on the materials is greatly improved, and the loosening and pushing of wet materials are facilitated. In a preset circumferential direction (e.g. clockwise direction), the initial threshing teeth a on the following bridging rod 12 are staggered by a step distance l in a fixed direction compared with the initial threshing teeth a on the preceding bridging rod 12, i.e. all threshing teeth 13 on the adjacent bridging rod 12 are staggered compared with the corresponding threshing teeth 13 on the preceding bridging rod 12, and the beneficial effects are that: further improves the continuity in threshing, ensures that the moist material is always subjected to the action of the threshing teeth 13, reduces the blockage of the roller, ensures that the material moves smoothly in the material channel, reduces the obstruction effect on the roller and can save energy consumption. Therefore, the threshing teeth 13 contained on the threshing cylinder 1 can be distributed along the spiral line, the spiral line where the threshing teeth 13 are located is consistent with the spiral direction of the bridging rod 12, and the spiral pitch of the spiral line where the threshing teeth 13 are located is far smaller than the spiral pitch of the bridging rod 12, so that the threshing teeth 13 are staggered, and threshing and pushing of materials are facilitated.
Furthermore, the threshing cylinder 1 comprises a middle plate 14 arranged centrally with respect to the two side plates 11, all the middle parts of the bridging bars 12 being connected to the middle plate 14.

The material moves on the main screen 41 from front to back, the drum 53 and the turning joint 52 are coaxially installed, and the rotation shafts of the drum and the turning joint extend from left to right.
The width of the bar-shaped groove 531 is larger than or equal to the diameter of the guide rod 512, and since the rotation speed and the rotation direction of the guide wheel 51 and the rotating drum 53 are different, the guide wheel 51 is not fixed relative to the turning joint 52, and when the rotating drum 53 rotates, the edge of the bar-shaped groove 531 pushes the guide rod 512 to move, so that the whole guide wheel 51 rotates relative to the turning joint 52.
With the above structure, when the direction-changing joint 52 rotates, the relative rotation shafts of the guide wheel 51 and the direction-changing joint 52 rotate around the central shaft of the rotary drum 53, the surfaces swept by the relative rotation shafts are conical surfaces, the top point of the conical surface is the intersection point of the relative rotation shaft and the central shaft of the rotary drum 53, and the guide wheel 51 independently rotates relative to the direction-changing joint 52, so that the guide wheel 51 swings left and right and rotates to perform space compound motion, the guide wheel 51 can interfere and guide the materials on the main screen 41, the collision between the materials is increased, the wrapping and clamping effect of angle shells and other sundries on crop seeds is reduced, the looseness and uniformity of the screened materials are improved, the screening pressure is reduced, the screen surface blockage is prevented, and the screening probability of the crop seeds is improved.
Preferably, the guiding mechanism 5 includes a plurality of guiding wheels 51 distributed in the left-right direction. Because the inducer 51 performs space compound movement, the operation width is larger, and the layout number of the inducer 51 can be reduced.
In addition, a plurality of groups of flow guiding mechanisms 5 are arranged in the front-back direction of the main screen body 41, so that materials can be interfered for a plurality of times when moving from front to back on the main screen body 41, and the loose degree of the materials is kept.
