[0036] Specifically, the slider 611 is moved, guided and limited by the support plate 607, and the sliding column 612 is moved in the reciprocating groove thereon by the rotation of the reciprocating roller 609, thereby driving the slider 611 and the nozzle 704 thereon to reciprocate, so that the nozzle 704 moves forward and backward and left and right at the same time, thereby achieving comprehensive spraying of broccoli cultivated in the placement frame 300.

[0037] The spraying mechanism 700 in the present invention includes a delivery pump 701 fixedly connected to the vertical frame 501, the input end of the delivery pump 701 is connected to a telescopic tube 1 702, the lower end of the telescopic tube 1 702 is connected to the bottom of the liquid medicine tank 100, the output end of the delivery pump 701 is connected to a telescopic tube 2 703, the upper end of the telescopic tube 2 703 is fixedly connected to a nozzle 704, and the nozzle 704 is fixedly connected to the surface of the slider 611.
