In the extended spreader 160, an extension socket 165 configured the same as the supply socket 140 is installed in the center of the extended spreader 160, and is inserted into the extension socket 165 at the end of the extended spreader 160 An extension coupler 163 having the same configuration as the socket coupler 155 to be coupled is installed so that the extension coupler 163 can be inserted into the extension socket 165 and coupled to each other.

Of course, the pesticide supplied from the pesticide spreading table 150 may be supplied to the extension socket 165 .

On the other hand, the extension socket 165 is installed to be rotatable in the left and right directions by the rotary coupling part 167 in the extension spreader 160, and pesticide spraying is applied to the extension socket 165 through the rotation coupling part 167. Agrochemicals supplied to the stand 150 may be supplied.

In addition, a weight 169 extending downward from the lower portion of the extension socket 165 and having a weight may be installed at an end thereof.

The weight weight 169 applies a load to the lower part of the extension spreader 160, so that even if the electric vehicle 200 shakes in the direction of gravity while driving, the pesticide is removed from the extension spreader 160 by the rotation coupling part 167. Since the spreading table 150 can maintain a vertical position while rotating, when the electric vehicle 200 is running, the relatively long extended spreading table 160 is shaken and separated from the pesticide spreading table 150, or the extended spreading table 160 ) It is possible to prevent damage to the extension spreader 160 or damage to crops while crops collide with them.

In addition, an extension control valve 166 for selectively supplying or blocking pesticides from the extension socket 160 to the extension socket 165 is installed in the extension socket 165 to selectively spray the pesticide from the extension spreader 160. It can be sprayed or blocked.

The extension control valve 166 may be configured to receive pesticide from both sides of the connection blocking part 153 located in the center of the pesticide spreading table 150 and supply it to the extended spreading table 160 or block it.

On the other hand, when the extended spreader 160 is coupled to the pesticide sprayer 150, since the pressure to supply the pesticide needs to be increased, a pneumatic pump is further installed to mix the compressed air in addition to the electric pump 110 for supplying the pesticide. can

In addition, the pneumatic pump is connected to the discharge hose 130 together with the electric pump 110 to supply compressed air to the discharge hose 130 by increasing the pressure of the discharge hose 130 and coupling it to the pesticide spraying table 150. The extended spreader 160 can discharge pesticides together with air.
