The invention relates to the field of 
agriculture, and particularly discloses a 
pesticide mixing device for extruding and flow pushing for 
agriculture. The 
pesticide mixing device for extruding and flow pushing for 
agriculture comprises a shell, a base, a feed hopper and a 
discharge pipe; a vertical extruding and flow pushing cylinder with an upward opening is coaxially fixed in the shell, a vertical downward 
hydraulic cylinder is fixed on the top of the shell, a vertical connecting rod is fixedly connected to the lower end of a 
piston rod of the 
hydraulic cylinder, and a horizontal extrudingand flow pushing plate matched with the inner wall of the extruding and flow pushing cylinder is fixed at the 
tail end of the 
hydraulic cylinder; and a plurality of liquid inlet holes are formed in the side wall of the middle of the extruding and flow pushing cylinder, and a liquid suction 
sponge is placed on the bottom of the extruding and flow pushing cylinder. According to the 
pesticide mixingdevice, liquid flows in the extruding and flow pushing cylinder, the extruding and flow pushing plate moves vertically to drive the liquid in the extruding and flow pushing cylinder to stir, meanwhile, the liquid flows in the liquid suction 
sponge in the extruding and flow pushing cylinder, a pesticide is easy to disperse by fine meshes in the 
sponge, the liquid continuously flows in and out of the pesticide mixing device through the extruding and flow pushing cylinder, and thus, the fluidity is improved.
