The application discloses a melon
seedling topping machine, which comprises a carrier and a bracket, and a reciprocating
cutting tool head is arranged on the bracket and used for
topping operation, characterized in that the bracket is provided with a tool head automatic cleaning
assembly and a height adjusting mechanism for driving the reciprocating
cutting tool head to ascend and descend and adjust height; the meshing transmission of the bracket
side tooth column and the tooth plate drives the synchronous ascending and descending of the connecting block and the side frame along with the reciprocating
cutting tool head, so that the resetting action of the tool head after
topping and the pneumatic transmission action of the side frame extruding the pressing block are synchronously worked, and an independent driving unit does not need to be additionally added; through the transmission cooperation of the rack gear and the eccentric disc protruding column, the stretching block is driven to extrude the washing liquid in the injection box, the cutting surface of the tool head is directionally sprayed through the spray bar, the mechanical linkage synchronous completion of the topping operation and the tool head cleaning is realized, the residual
seedling juice and stem debris on the surface of the reciprocating
cutting tool head can be quickly removed, and the
bacteria are prevented from being transferred to the fresh incision of the healthy
plant through the tool.
