Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
As shown in Figure 2, the cross drive mechanism of the agricultural rice transplanter of the utility model, the left end of material feeding box 3 is provided with left seal cover 1 and left charging case lid 2, the right-hand member of described material feeding box 3 is provided with right charging case lid 5 and right seal cover 9, the bottom righthand side place of rice transplanter casing is provided with seedling planting axle 14, described seedling planting axle 14 is provided with first driving gear 13 and second driving gear 12, be engaged with duplex driven gear parts 6 with first driving gear 13, the power transmission shaft of described duplex driven gear parts 6 is leads screw for cross-slide 4, be provided with manual shift mechanism between described lead screw for cross-slide 4 and the seedling planting axle 14, described manual shift mechanism comprises first driving gear 13 and second driving gear 12 that is arranged on the described seedling planting axle 14, the axial end of described lead screw for cross-slide 4 is provided with duplex driven gear parts 6, described duplex driven gear parts 6 comprise first driven gear 61 and second driven gear 62, described duplex driven gear parts 6 are connected with the shift fork structure, described shift fork structure comprises a shifting fork bar 8, one end of described shifting fork bar 8 exposes to outside the rice transplanter casing and is fixed with one handle 10, and the other end of described shifting fork bar 8 is provided with and is inserted in the shift fork 7 in the draw-in groove between described first driven gear 61 and second driven gear, 62 adjacent faces; That is: described shift fork 7 links to each other with described shifting fork bar 8, and described shifting fork bar 8 links to each other with handle 10.The position limiting structure that also comprises duplex driven gear parts 6, this position limiting structure comprise first groove 81 that is arranged on the shifting fork bar 8 and second groove 82 and are arranged on the lead screw for cross-slide 4 and are positioned at two spacing back-up rings 11 in the described duplex driven gear parts outside; As shown in Figure 3, there is a steel ball 15 to be arranged on rice transplanter box body wall (Fig. 2 shows on the right seal cover 9 of rice transplanter material feeding box 3) processing one hole, the outer end in this hole is provided with bolt 17, put into a spring 16 at this Kong Zhongxian and put into steel ball 15 again, pressure by spring 16 can apply a pressure with this steel ball 15, be steel ball 15 by roof pressure in described first groove 81 or second groove 82.Fig. 1 shows the end of mutual alignment relation between lead screw for cross-slide 4, seedling planting axle 14 and the handle 10 and right seal cover 9 to geometry.
