Embodiment

Embodiment 1: the preceding land wheel 11 that this small cultivator comprises frame 14, be contained in the frame bottom and back land wheel 15, engine 6, gearbox 3, the driving-disc 19 that is connected with gearbox 3, the plane bar 8 that is hinged with driving-disc 19 and the planer head 10 that is contained in plane bar front end.Four land wheels are hinged on the bottom, front and back of frame 14 respectively by wheel shaft and bearing 21.Engine 6 and gearbox 3 all are fixed on the frame 14, and driving-disc 19 is fixed on the driving shaft 13, and driving shaft 13 is fixed on the frame 14 by bearing block 20.Engine 6 is connected with gearbox 3 with

belt pulley

4,7 by belt 5.Gearbox 3 has two clutch ends, and one is connected with the wheel shaft of walking chain 16 with back land wheel 15 by

walking sprocket wheel

17,18, drives machine and walks; Another is connected with driving shaft 13 with driving chain by

drive sprocket

2,12, by drive driving-disc 19 rotate make the planer head 10 that digs the bar front end produce before and after displacements and swinging up and down.Gearbox 3 is provided with to regulate and digs the plane the ground control crank 1 of frequency of bar.In the present embodiment, in order to make machine both sides producing balanced forces when working, described driving-disc 19 and plane bar 8 are set to two respectively, two plane bars 8 are installed in the right and left of frame with respect to longitudinal center's symmetry of machine, simultaneously in order to increase work efficiency, be convenient to interplant farming, the width of frame 14 is set to the line-spacing less than the plantation crops.All be provided with the groove 24 that play the guiding role on the radial location of each driving-disc 19, in each guide groove 24 fixed block 22 be housed, each fixed block 22 is fixed on the driving-disc 19 by pin and the pin-and-hole that is disposed on the guide groove bottom surface.The rear end of digging bar 8 is hinged on the fixed block 22 by pin respectively, the front portion of two plane bars 8 is equipped with sliding sleeve 9 respectively, two sliding sleeves 9 are hinged on respectively on the wheel shaft of preceding land wheel 11 both sides of frame, digging bar 8 both can move axially in sliding sleeve 9, can rotate around pin joint again, driving-disc 19, dig bar 8 and the sliding sleeve 9 generation crank rod movement of working in coordination, thus drive dig the bar front end planer head 10 by the front and back displacement with swing up and down and dig native operation.The position of mobile fixed block 22 in guide groove 24 can change the length of formed crank between A, the B at 2, and then changes the amplitude that planer head 10 swings up and down and the distance of displacement.Under the soft situation of soil property, the installation site of two side planing bars 8 can symmetry, also can be asymmetric, i.e. and the action of both sides planer head 10 can be synchronous, also can be asynchronous.Hand steered operating machines is provided with hand rod 25 above frame 14 rear ends for convenience.Change farm implements for convenience, planer head 10 is set to dig on the bar 8 by being bolted to, when carrying out the operation of other kind, can unload planer head 10, other farm implements that are suitable for are fixed by bolts to dig on the bar 8.For handling safety, also can load onto backplate at the correct position of frame 14 neighborings.
