A highly efficient self-propelled plant protection machine for weeding, insecticide, and sterilization is forced to be mass-produced in response to demand. The water pump of a conventional self-propelled plant protection machine needs to obtain driving force through the third power output shaft of the gearbox. Because the installation position of the plant protection machine water pump is installed under the driver's seat or on both sides for easy operation, the driver's hand can operate the close position. The power of the conventional gearbox cannot be cut off independently, forcing the water pump drive shaft to be equipped with a mechanical clutch. The driver manually operates the clutch to the required "separation" or "combination" position according to demand during driving. To achieve the required working mode, but this structure is a mechanical conventional pulley to transmit power. The driver needs to observe the driving route every year because of the need for eyes. When operating the clutch state, the fingers are accidentally pinched by the pulley and the belt. Severe cases can cause the entire arm to be entangled in the pulley and cause disability.

[0018] Example 1

[0019] See also Figure 1-Figure 4 As shown, this embodiment provides a self-propelled plant protection machine water pump power output electromagnetic clutch gearbox, which at least includes a gearbox power input shaft 1a, an electromagnetic clutch driving gear 2a, an electromagnetic clutch support bearing 5, an electromagnetic clutch power support shaft spline sleeve 7 and an electromagnetic clutch stator 11, characterized in that: the gearbox power input shaft 1a is processed with equidistantly distributed splines on the outer circle and is spline-connected with the electromagnetic clutch driving gear 2a, one side of the electromagnetic clutch driving gear 2a is meshed with a third power output shaft driven gear 6, one side of the third power output shaft driven gear 6 is provided with an electromagnetic clutch power shaft 8, the third power output shaft driven gear 6 is spline-connected with the electromagnetic clutch power shaft 8, the electromagnetic clutch stator 11 is slidably connected to the electromagnetic clutch power support shaft spline sleeve 7 through the electromagnetic clutch support bearing 5, and the electromagnetic clutch power support shaft spline sleeve 7 is spline-connected with the electromagnetic clutch power shaft 8 through a spline.

[0020] An electromagnetic clutch friction plate 1 is provided on the rear side of the spline sleeve 7 of the electromagnetic clutch power support shaft. A spline is processed on the rear end of the spline sleeve 7 of the electromagnetic clutch power support shaft and is plugged into the inner spline of the electromagnetic clutch friction plate 1. A plurality of clutch pressure plates 2 are slidably connected to the spline sleeve 7 of the electromagnetic clutch power support shaft. Passive finger pins 3 are plugged into the outer spline grooves of the plurality of clutch pressure plates 2. The passive finger pins 3 are riveted with power transmission gears 4 by bolts. The power transmission gear 4 is mounted on the electromagnetic clutch power shaft 8 through a floating sliding assembly. A power output shaft drive gear 10 is meshed on one side of the power transmission gear 4. A third power output shaft 9 is plugged into the power output shaft drive gear 10. A power output pulley 12 is installed on the tail end spline of the third power output shaft 9 for final power output transmission. The electromagnetic clutch stator 11 is fixed to the gearbox through a side wall positioning hole.

[0021] The above working principle: according to the connection mode of each part and component, the power is transmitted to the electromagnetic clutch driving gear 2a through the gearbox power input shaft 1a, and the electromagnetic clutch driving gear 2a is meshed with the third power output shaft driven gear 6, so the power is transmitted to the third power output shaft driven gear 6, and the third power output shaft driven gear 6 transmits the power to the electromagnetic clutch power shaft 8 which is splined, and the electromagnetic clutch power shaft 8 transmits the power to the electromagnetic clutch power support shaft spline sleeve 7 which is also splined. An electromagnetic coil is installed in the electromagnetic clutch stator 11. When the power is on, the electromagnetic suction force attracts and presses the clutch pressure plate 2 and the electromagnetic clutch friction plate 1 together, and the power is transmitted through the electromagnetic clutch power support The support shaft spline sleeve 7 is transmitted to the electromagnetic clutch friction plate 1 connected through the spline. Because multiple clutch pressure plates 2 and the electromagnetic clutch friction plate 1 transmit power to multiple clutch pressure plates 2 through friction pressure, the power is output to the power transmission gear 4 through the passive finger pin plate 3 inserted in the groove of the multiple clutch pressure plates 2. If the electromagnetic coil installed in the electromagnetic clutch stator 11 is powered off, because the clutch pressure plate 2 is a sliding multi-piece arrangement in the middle of the electromagnetic clutch friction plate 1, because there is no electromagnetic force attraction, no friction is generated between the electromagnetic clutch friction plate 1 and the clutch pressure plate 2, and power cannot be transmitted to the clutch pressure plate 2, so the power cannot be output and transmitted to the rear end.

[0022] When the electromagnetic clutch gearbox for the power output of the water pump of the self-propelled plant protection machine in this embodiment is used, the power is transmitted to the electromagnetic clutch driving gear 2a through the gearbox power input shaft 1a, and then the power is transmitted to the meshing third power output shaft driven gear 6, the third power output shaft driven gear 6 transmits the power to the electromagnetic clutch power shaft 8 splined, the electromagnetic clutch power shaft 8 transmits the power to the electromagnetic clutch power support shaft spline sleeve 7 which is also splined, an electromagnetic coil is installed in the electromagnetic clutch stator 11, and the electromagnetic suction force attracts and presses the clutch pressure plate 2 and the electromagnetic clutch friction plate 1 together when powered, the power is transmitted to the electromagnetic clutch friction plate 1 splined through the electromagnetic clutch power support shaft spline sleeve 7, the electromagnetic clutch friction plate 1 transmits the power to multiple clutch pressure plates 2 through friction pressure, and the power is output to the power transmission gear 4 through the passive finger pin plate 3 inserted in the notch of the multiple clutch pressure plates 2, if the electromagnetic coil in the electromagnetic clutch stator 11 is powered off, the power cannot be output and transmitted to the rear end.
