mounted on the pedestal 41, the power input shaft 431 and the crank 421 are sequentially connected, and power input shaft 431 is connected with the second motor drive；The acceleration size adjusting part 432 includes the first peace Shelve the 4321, first motor 4322, leading screw 4323, eccentric mounting 4324, H-type mounting bracket 4325, the first pivoted arm 4326, the second pivoted arm 4327 and axle sleeve 4328, first motor 4322 be arranged on first mounting bracket 4321 and be driven with the leading screw 4323 Connection, the leading screw 4323 are spindle rotationally arranged on first mounting bracket 4321, and the eccentric mounting 4324 is slidably arranged in On first mounting bracket 4321, threaded hole is offered on the eccentric mounting 4324, the leading screw 4323 is threaded in described In threaded hole, the H-type mounting bracket 4325 is spindle rotationally arranged on the eccentric mounting 4324, and the axle sleeve 4328 is sleeved on described On power input shaft 431,4326 one end of the first pivoted arm is arranged on the axle sleeve 4328, first pivoted arm 4326 The other end is slidably arranged in the sliding slot that the H-type mounting bracket 4325 is formed, and 4327 one end of the second pivoted arm is set On the power input shaft 431, the other end of second pivoted arm 4327 is slidably arranged in 4325 shape of H-type mounting bracket Into another sliding slot in；The axle sleeve 4328 is sequentially connected with the crank 421.Specifically, it is driven by the first motor 4322 Leading screw 4323 rotates so that eccentric mounting 4324 drives H-type mounting bracket 4325 to move, so that the rotation of H-type mounting bracket 4325 The axis runout of axis and power input shaft 431 is opened, in this way, the first pivoted arm 4326, the second pivoted arm 4327 is just caused to be installed with H-type The distance of the pivot center of frame 4325 changes, and in 431 rotation process of power input shaft, power input shaft 431 drives the Two pivoted arms 4327 rotate, and by the second pivoted arm 4327 axle sleeve 4328 are driven to rotate, so as to drive 421 turns of crank by axle sleeve 4328 It is dynamic, after being opened due to the pivot center of H-type mounting bracket 4325 and the axis runout of power input shaft 431, the first pivoted arm 4326 and the The radius of gyration for the end that two pivoted arms 4327 are contacted with H-type mounting bracket 4325, can be in power input shaft 431 at the uniform velocity by difference During rotation, the velocity of rotation of the second pivoted arm 4327 at different position is different, is rotated so as to fulfill 421 speed change of crank, It during burying, can cause the faster rotational speed of crank 421, so as to rearward be shed to the soil dug out by hoe 40, subtract The falling amount of few soil, to obtain deeper plantation hole.Preferably, for the planting depth requirement of different seeds, then need to adjust Hoe 40 is saved into the velocity variations position of underground layer, the gearshift adjustment component 43 further includes angular adjustment component 433, the angle Spending adjusting part 433 includes the second mounting bracket 4331, the second motor 4332, worm screw 4333 and turbine 4334, second installation Frame 4331 is fixed on the pedestal 41, and circular hole is provided on second mounting bracket 4331, and the turbine 4334 is located at described In circular hole, the worm screw 4333 engages with the turbine 4334, and second motor 4332 is sequentially connected with the worm screw 4333, Guide groove 43341 is offered on the turbine 4334, the eccentric mounting 4324 is slidably arranged in the guide groove 43341, and described One mounting bracket 4321 is fixed on the turbine 4334.Specifically, by controlling 4325 shaft axis of H-type mounting bracket and power defeated Enter the horizontal distance of axis 431, then can control 421 velocity variations size of crank, and by adjusting 4325 shaft axis of H-type mounting bracket The vertical distance of line and power input shaft 431, then can adjust the velocity variations point position of crank 421, and the second motor 4332 drives The dynamic worm screw 4333 rotates so that turbine 4334 rotates, in this way, just so that 43341 run-off the straight of guide groove, eccentric mounting 4324 exist In moving process, the shaft axis inclination movement of H-type mounting bracket 4325 can be controlled, to adjust the velocity variations of crank 421 The position of point and hoe 40 matches.Wherein, since the amount of deflection of worm screw 4333 and the adjusting eccentric mounting 4324 of turbine 4334 is limited, When beyond adjustable range, then need to be adjusted by such as lower structure：Dismountable first gear is provided on axle sleeve 4328 43281, rotatable turntable 4329 is additionally provided on power input shaft 431, is additionally provided on the turntable 4329 and
