Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises:

1) two airflow vibrating type ordered seedling throwing and separating mechanisms that structure is identical: the vibrating board 1 that is driven by vibrating mechanism 18 is fixed on the frame 13 by flat spring 17 respectively, vibrating board 1 enters to have on the pot seedling 4 one end plate faces some and interval, can under the inertia force effect, adjust the spike-tooth 3 of the direction of pot seedling 4, vibrating board 1 is equipped with side shield 2, side shield 2 is at the initial part broad, dwindle gradually then, the aft section of vibrating board 1 is can allow air communication cross make the upright net grid 5 of pot seedling, its cross section can be that identical (Fig. 4 a) for the native alms bowl with pot seedling, for trapezoidal, also can be soil bowl shape with pot seedling be close (Fig. 4 b), for square, or arc or other approaching shape, be the source of the gas (can be blower fan) 9 that produces air-flow in its lower section, air communication is crossed the space of the upright net grid 5 of pot seedling is up blown, when pot seedling moves to herein, because the effect of air-flow makes pot seedling 4 become native alms bowl following by original level, pot seedling 4 leaves are in last upright posture, the exit of the groove of every net grid all is provided with block 6, block 6 front end settings are identical with the groove number of net grid, seedling teasing wheel 7 by 19 drivings of thumb wheel axle, be connected to before each seedling teasing wheel 7 and lead seedling pipe 8, thumb wheel axle 19 is bearing in thumb wheel axle supporting base 21, storage seedling case 22 is fixed on the frame centre position, promptly is located between two airflow vibrating type ordered seedling throwing and separating mechanisms;

2) power is received vibrating mechanism 18, is received source of the gas (blower fan) 9, receives seedling teasing wheel reduction box 10 through universal drive shaft 11 through transmission mechanism through transmission mechanism respectively by gearbox 12, and seedling teasing wheel reduction box 10 is received seedling teasing wheel 7 through thumb wheel axle 19;

3) frame 13 is fixed on the planker 14, and planker 14 links to each other with draw-

gear

15, and 16 is cushion.

Design some and spike-tooth 3 at interval on the initial part plate face of vibrating board 1, its objective is and guarantee that pot seedling 4 runs into the direction that can adjust pot seedling behind the spike-tooth under the inertia force effect in motion process, make with one of native alms bowl and headfirst advance the direction motion, help the conveying of pot seedling, prevent the pot seedling stack up.Add side shield 2 at vibrating board 1, prevent that pot seedling from dropping, side shield 2 is at the initial part broad, dwindle gradually then, force pot seedling to shrink (see figure 3) toward the center of oscillating plate, the aft section of vibrating board 1 be one can allow air communication crosses make the upright net grid 5 of pot seedling, its cross section is identical with the native alms bowl of pot seedling, (Fig. 4 a) for trapezoidal, also can be that soil bowl shape with pot seedling is close, be square (Fig. 4 b) or arc, be the source of the gas (blower fan) 9 that produces air-flow in its lower section, air communication is crossed the space of the upright net grid 5 of pot seedling is up blown, when pot seedling 4 moves to herein, because the effect of air-flow makes pot seedling 4 become native alms bowl following by original level, pot seedling 4 leaves are in last upright posture, have only the native alms bowl of pot seedling 4 to contact with net grid 5, a groove in the net grid only allows a row pot seedling 4 to pass through, under the vibration force effect, pot seedling 4 is motion forward in groove, one block 6 is set in the exit of every groove, block pot seedling 4, force pot seedling 4 to produce viscous flow herein, because the pot seedling 4 of back is constantly imported, sample can make pot seedling 4 form a line automatically near block 6, when seedling teasing wheel 7 rotation, seedling teasing wheel 7 pawls pot seedling 4 many ground dial from, pot seedling 4 falls into Tanaka along leading seedling pipe 8 slideways, become erectility, finish the ordered seedling throwing operation.

Described its cross sectional shape of net grid is to be made up of one or more groove, and it is trapezoidal that the cross sectional shape of groove and the native alms bowl of pot seedling are all mutually, perhaps square the or circular arc that is close with the soil bowl shape of pot seedling.

Described vibrating mechanism 18 is toggles, or inertial oscillation mechanism, reaches the vibrating mechanism of vibrating transportation.

Storage seedling case 22 is to store the pot seedling that takes off from the seedling dish, operating personnel during work, pot seedling with manually putting into vibrating board 1.

Making the upright net grid 5 of pot seedling is most important parts, it is the part of vibrating board 1, other parts Joint with vibrating board 1, this part basic thought is that air-flow can be passed through, and windage is as far as possible little, and the net grid can be the various structures that can allow air communication cross, the cross section of net grid can be formed (see figure 4) by several grooves, pot seedling is marshalling in groove, as required multiple row can be set, and Fig. 4 shows and has been listed as 3., the delegation during the corresponding rice transplanting of groove is if 6 row then need 6 grooves.The direction of groove be along vibrating board 1 vibration vertically.Article one, groove can only hold a row pot seedling and passes through, and its size is bigger slightly than pot seedling, and it is unimpeded to guarantee that pot seedling passes through.

This throwing transplanting machine has structurally been arranged two vibrating boards 1, and symmetric arrangement is furnished with source of the gas (blower fan) below each vibrating transportation expanded metals grid 5, and the air port is over against net grid 5.

Block 6 can be to be fixed on the frame, also can be to be fixed in the vibrating transportation mechanism, purpose is to block pot seedling, do not allow the pot seedling free-falling, make pot seedling retention herein, the marshalling on certain-length that the pot seedling of catching up with later is many allows pusher dog many dial-outs in an orderly manner of seedling teasing wheel 7, and seedling teasing wheel 7 is driven by thumb wheel axle 19 and is rotated counterclockwise (pressing Fig. 1); The quantity of block 6 is consistent with the quantity of the groove of net grid.

Lead seedling pipe 8 tops (pot seedling porch) and separated by dividing plate, bottom (pot seedling exit) is separated by a distance according to rice transplanting needs line-spacing, and each exports corresponding delegation rice shoot.Be provided with according to the line number needs.

It is consistent with the crest number of planker 14 to lead seedling pipe 8 quantity.The lower end of leading seedling pipe 8 is corresponding with the crest center of planker respectively.

Pot seedling 4 to the ooze slurry of being extruded by the crest of planker, is finished ordered transplantation by gravity fall.Once can finish the capable operation of 6-8, line-spacing can be led the position adjustment of seedling pipe lower end by change, and spacing in the rows is determined by machine forwarding speed.

Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
