The guide plates 702 can slide in the adjusting long holes 703 on the second grass guide plate through the connecting bolts 704 to adjust the relative distance, when the guide plates 702 on the two sides slide downwards and inwards along the adjusting long holes 703, the distance between the guide plates 702 is reduced, and the pasture laying width is reduced accordingly; when the guide plates 702 on the two sides slide upwards and outwards along the adjusting long holes 703, the distance between the guide plates 702 is increased, and the pasture laying width is widened accordingly, so that the function of adjusting the laying width is realized. The front end of the second grass blocking plate 701 is connected with the left side wall and the right side wall of the header body through bolts, and the connecting parts can rotate around the bolts. The rear end is hung on the whole machine frame by using a hanging chain 705, and the length of the hanging chain 705 hung on the whole machine frame determines the relative height of the tail part of the second grass baffle 701 from the ground. When the connection length of the hanging chain 705 and the rack is short, the distance from the tail part of the second grass guide plate 701 to the ground is high, and the blocking time for the pasture is short, so that the pasture is fluffy after being laid; when the connection length of the hanging chain and the rack is longer, the distance from the tail part of the large grass guide plate to the ground is shorter, and the blocking time of the pasture is longer, so that the pasture is more dense after being laid, and the function of adjusting the laying density of the pasture is realized. The bottom of the second grass guiding plate is also provided with a fixed auxiliary grass guiding plate 706, and when grass contacts and passes through the bottom of the second grass guiding plate 701, the auxiliary grass guiding plate 706 can guide the grass to move towards the tail of the auxiliary grass guiding plate 706 and the direction of the guide plate 702.

Because the header is bilateral symmetry and arranges, therefore the transmission on header right side is similar with left transmission, and universal joint transmission power mode and regulation flatten roller clearance mode also are unanimous with the header left side, and the left and right sides of header body all possesses adjusting cylinder, regulation support, straining device, first grass poking wheel, second grass poking wheel, pushing screw feeder and first gag lever post and second gag lever post. The difference lies in that header right side transfer case only transmits power to a set of pinch rolls of header body rear side, and rear side top pinch rolls and rear side below pinch rolls promptly are not connected with the spindle nose of lift roll. The forage that a set of pinch rolls of header body rear side, rear side top pinch rolls and rear side below pinch rolls carried the front side flattens once more and discharges promptly, and the first fender grass board of upper back of header body is contacted earlier to exhaust forage, contacts the second fender grass board in header body rear side again behind first fender grass board, falls subaerially at last to this realizes the forage process of laying. First fender grass board has the forage grass direction function, avoids forage grass to be got rid of header top and tire surface because of self inertia after being discharged by flattening roller. The second grass blocking plate has the function of adjusting the laying width and the laying density, the appearance of the second grass blocking plate is trapezoidal, and when the forage grass passes through the second grass blocking plate, the forage grass is converged by the guide plate at the bottom of the second grass blocking plate together, so that the forage grass falls in the middle of the rack of the whole machine, and the tire is prevented from rolling the forage grass.
