Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the stereogram of the utility model embodiment;
Fig. 2 is the structural representation of middle clutch part embodiment illustrated in fig. 1;
Fig. 3 is a spacing principle schematic embodiment illustrated in fig. 1.
Embodiment
A kind of improved hand-held transplanter, shown in Fig. 1 and Fig. 2 were common, it comprised frame, is used for the transmission case 4 to transplant arm 2 transferring power, power shaft 41 two ends of described transmission case are stretched out the transmission case casing and are rotatably installed on the described frame; Seedling feeding device 1, described seedling feeding device 1 comprises the helical axis 11 that is used for horizontal seedling sending, described helical axis 11 is rotatably installed on the described frame; Be provided with first transmission device between the power shaft 41 of described transmission case and the power set of rice transplanter, be provided with second transmission device between the power shaft 41 of described transmission case and the helical axis 11 of seedling feeding device, described first transmission device and second transmission device constitute by chain and sprocket driving device.
As shown in Figure 2, be installed on the clutch 5 on the power shaft 41 of described transmission case, be used to control the manipulation device of described clutch 5 clutches.
The described clutch 5 preferential dog clutches of selecting, described dog clutch comprises initiatively half-clutch device 53 and driven half-clutch device 52, half-clutch device 53 sliding sleeves of described active are on the power shaft 41 of described transmission case, described driven half-clutch device 52 keys are connected on the power shaft 41 of described transmission case, are sheathed on the power shaft 41 of described transmission case and can apply the compression spring 51 of axial clamping force to described two half-clutch devices.
