The present embodiments also provide a seeding machine including the seeding machine drive system of the present embodiments.

The working principle of the seeder driving system of the embodiment is as follows: when the output rotation direction of the transmission shaft 23 is a forward direction (i.e. the forward direction of the seeder), the first control mechanism and the second control mechanism are as shown in fig. 3a, when the first positioning member is braked by the first brake member by the first control mechanism and the second control mechanism, the first inner gear ring cannot rotate freely, the transmission shaft 23 rotates forward to drive the first planetary gear set to rotate, so that the first fixing member is driven to rotate forward, the rotation direction in the same direction as that of the transmission shaft 23 is output, the front wheel and the rear wheel rotate forward, and the seeder moves forward to sow seeds; when one of the first control mechanism and the second control mechanism does not brake the first positioning piece, the first inner gear ring of the control mechanism on the side which is not braked can rotate freely, the first sun gear and the first planetary gear are driven to rotate by the transmission shaft 23, the first fixing piece does not rotate, no power is transmitted outwards, the power transmission on the side which is not braked is blocked, the front wheel and the rear wheel on the side are unpowered, the other side keeps rotating forwards, and the seeder turns to the side which is not braked. Or, as shown in fig. 3b, the first control mechanism and the second control mechanism separate the second planetary gear assembly 211 ' from the second detent 213 ', and detachably connect the second positioning member 212 ' and the second detent 213 ' with the sixth connecting portion through the fourth connecting portion 2122 ', at this time, the second detent 213 ' brakes the second positioning member 212 ', the second ring gear cannot rotate freely, the transmission shaft 23 ' rotates forward to drive the second planetary gear set to rotate, so as to drive the second fixing member to rotate forward and output a rotation direction in the same direction as the transmission shaft 23 ', further, both the front wheel and the rear wheel rotate forward, and the seeder moves forward to sow; when one of the first control mechanism and the second control mechanism does not brake the second positioning piece, the second inner gear ring of the control mechanism on the side which is not braked can rotate freely, the second sun gear and the second planetary gear are driven to rotate by the transmission shaft 23, the second fixing piece does not rotate, no power is transmitted outwards, the power transmission on the side which is not braked is blocked, the front wheel and the rear wheel on the side are unpowered, the other side keeps rotating forwards, and the seeder turns to the side which is not braked.

When the output direction of the transmission shaft is reverse (namely, the direction opposite to the advancing direction of the seeder), the first control mechanism and the second control mechanism are shown in fig. 3b, when the first control mechanism and the second control mechanism brake the second planetary gear assembly through the second brake piece, the second fixing piece cannot rotate, the second planetary gear set arranged on the second fixing piece cannot revolve, the transmission shaft 23 'rotates reversely to drive the second inner gear ring to rotate, so that the second positioning piece is driven to rotate positively, the rotating direction opposite to the transmission shaft 23', namely, the forward direction is output, further, the front wheels and the rear wheels both rotate positively, and the seeder advances to sow seeds; when one of the first control mechanism and the second control mechanism does not brake the second planetary gear assembly, the second planetary gear set of the control mechanism on the side which is not braked can revolve, the second sun gear and the second planetary gear are driven to rotate under the drive of the transmission shaft 23', the second positioning piece does not rotate, no power is transmitted outwards, the power transmission on the side which is not braked is blocked, the front wheel and the rear wheel on the side are unpowered, the other side keeps rotating forwards, and the seeder turns to the side which is not braked. Or, as shown in fig. 3a, the first control mechanism and the second control mechanism are configured to separate the first positioning element 212 from the first braking element 213, and detachably connect the first planetary gear assembly 211 and the first braking element 213 through the mutual engagement between the second connection portion 2114 and the third connection portion, at this time, the first braking element 213 brakes the first planetary gear assembly 211, the first fixing element cannot rotate, the first planetary gear assembly mounted on the first fixing element cannot revolve, the transmission shaft 23 rotates in reverse direction to drive the first ring gear to rotate, so as to drive the first positioning element to rotate in forward direction, and output a rotation direction opposite to that of the transmission shaft 23, that is, forward direction, so that both the front wheel and the rear wheel rotate in forward direction, and the seeding machine moves forward to sow seeds; when one of the first control mechanism and the second control mechanism does not brake the first planetary gear set, the first planetary gear set of the control mechanism on the non-braking side can revolve, the first sun gear and the first planetary gear are driven to rotate by the transmission shaft 23, the first positioning piece does not rotate, no power is transmitted outwards, the power transmission on the non-braking side is blocked, the front wheel and the rear wheel on the side are unpowered, the other side keeps rotating forwards, and the seeder turns to the non-braking side.

Therefore, when the first positioning member 212 and the first braking member 213 are non-detachably connected and the second planetary gear assembly 211 'and the second braking member 213' are non-detachably connected in the present embodiment, the first control mechanism and the second control mechanism can only select the first control mechanism and the second control mechanism including the first planetary gear assembly 211, the first positioning member 212 and the first braking member 213 braking the first positioning member 212 when the transmission shaft rotates forward, and the first control mechanism and the second control mechanism can only select the first control mechanism and the second control mechanism including the second positioning member 212 ', the second planetary gear assembly 211' and the second braking member 213 'braking the second planetary gear assembly 211' when the transmission shaft rotates backward. When the first positioning member 212 and the first braking member 213 are detachably connected and the second planetary gear assembly 211 ' and the second braking member 213 ' are detachably connected in the present embodiment, the first control mechanism and the second control mechanism including the first planetary gear assembly 211, the first positioning member 212 and the first braking member 213 have the same structure as the first control mechanism and the second control mechanism including the second positioning member 212 ', the second planetary gear assembly 211 ' and the second braking member 213 ' after the first positioning member 212 and the first braking member 213 are detached and the first planetary gear assembly 211 and the first braking member 213 are detachably connected, and the first control mechanism and the second control mechanism including the first planetary gear assembly 211, the first positioning member 212 and the first braking member 213 can be applied to both the forward rotation shaft and the reverse rotation shaft, and have higher adaptability. When the first positioning member 212 is detachably connected to the first braking member 213 and the second planetary gear assembly 211 'is detachably connected to the second braking member 213 in this embodiment, the first control mechanism and the second control mechanism including the second positioning member 212', the second planetary gear assembly 211 'and the second braking member 213', after the second planetary gear assembly 211 'is disassembled from the second stopper 213', and the second positioning member 212 'is detachably coupled to the second stopper 213', the structure of the mechanism is completely the same as that of the first control mechanism and the second control mechanism comprising the first planetary gear assembly 211, the first positioning member 212 and the first braking member 213, and the first control mechanism and the second control mechanism comprising the second positioning member 212 ', the second planetary gear assembly 211 ' and the second braking member 213 ' can be applied to the forward rotation or the reverse rotation of the transmission shaft, so that the adaptability is stronger.
