Occupation mode of the present utility model is as follows:

In kind of barrel 1, load onto seed, in fertilizer tube 2, load onto fertilizer, feet 23 is placed on the field, press handle 7 downwards, kind of barrel 1 and fertilizer tube 2 are moved down along guide rail 20, abdicate kind of mouth 5 and go out fertile mouth 6 and insert in the soil.

Plant barrel 1 and fertilizer tube 2 in folding process, move on first thrust axis, the 31 relative triggers 21, first thrust axis 31 is replaced into groove domatic 34, because the long slot bore 27 at trigger 21 middle parts is enclosed within on the locating shaft 28, so trigger 21 can be that the center deflects with locating shaft 28, during trigger 21 deflections, first thrust axis 31 can be crossed domatic 34 edges of groove and move back groove domatic 35 and enter in the groove 33, make protruding nose 26 protruding, pull bar 22 is in tensioned state.

Plant barrel 1 and fertilizer tube 2 in folding process, move on second thrust axis, the 32 relative shift forks 13, because declutch shift shaft is fixed, so, shift fork 13 can be that the center of circle upward deflects with the declutch shift shaft, shift fork ratchet chain wheel 14 is done and is turned clockwise, because ratchet has the characteristics of unidirectional transmission, so, divide 11 meetings of kind of the left ratchet chain wheel of roller 8 left ends along the axis direction play,, divide the stage clip that kind of right ratchet chain wheel of roller 8 right-hand members 12 and stage clip cover on 15 inner surfaces to cover teeth of the ratchet chain wheel 16 meeting changing of the relative positions owing to top spring 17 provides pretightning force, again engagement realizes the location then.Dividing also can teeth of the changing of the relative positions, engagement again then between kind of left ratchet chain wheel 11 of roller 8 left ends and the shift fork ratchet chain wheel 14.

The roller 9 of dividing booty is coaxial the connection with declutch shift shaft, roller 9 can turn clockwise with declutch shift shaft so divide booty, divide booty on the roller 9 break slot 19 can from towards the upset of the position of fertilizer tube 2 bottom openings towards going out fertile mouth 6, the fertilizer in the break slot 19 will be in the fertile mouth 6 that drops under the effect of gravity.

When kind barrel 1 and fertilizer tube 2 have moved down into the stroke end, the upper limit buffer stopper 41 at guide rail 20 tops withstands baffle plate 29, at this moment, going out kind of mouth 5 and going out fertile mouth 6 inserts in the soil fully, the release lever 7 of loosing one's grip then, owing to plant barrel 1 and fertilizer tube 2 in folding process, back-moving spring 30 is elongated, behind the release lever 7, under the effect of back-moving spring 30, plant barrel 1 and fertilizer tube 2 along moving on the guide rail 20, move past in the journey last, first thrust axis, 31 relative triggers 21 move down, compress out groove domatic 35 and withdraw from groove 33, because the long slot bore 27 at trigger 21 middle parts is enclosed within on the locating shaft 28, so trigger 21 can be the reverse deflection in center with locating shaft 28, during the reverse deflection of trigger 21, protruding nose 26 is upturned, by the pulling function of pull bar 22, use kind of mouth 5, go out renovating fast of fertile mouth 6 and start, go out kind of mouth 5, the seed and the fertilizer that go out in the fertile mouth 6 are fallen in the soil.

Plant barrel 1 and fertilizer tube 2 along moving past in the journey on the guide rail 20, second thrust axis, 32 relative shift forks 13 move down, because declutch shift shaft is fixed, so, shift fork 13 can be that the center of circle deflects down with the declutch shift shaft, shift fork ratchet chain wheel 14 is done and is rotated counterclockwise, promote to divide kind of the left ratchet chain wheel of roller 8 left ends 11 rotations, have seven ratchets on the shift fork ratchet chain wheel 14, during each release lever 7, shift fork ratchet chain wheel 14 all can promote 1/7th circumference of left ratchet chain wheel 11 rotations, divide kind of a roller 8 to be provided with seven row's pits 10, during each release lever 7, all can row's pit 10 rotate to towards under the position, the seed in this row's pit will be in kind of the mouth 5 that drops under the effect of gravity.

Kind of barrel 1 and fertilizer tube 2 be along moving past in the journey on the guide rail 20, and the break slot 19 on the roller 9 of dividing booty is become down by original direction and is directed upwardly, and the fertilizer in the fertilizer bucket 2 enter in the break slot 19, thereby finish once circulation.Whenever depress handle 7 once, said process comes again, thereby realizes sowing and fertilising.
