The utility model relates to the technical field of farm
irrigation, in particular to a small agricultural mechanical
irrigation device which comprises a bottom plate, a spraying
assembly is fixedly connected to the middle of the top end of the bottom plate, a material mixing
assembly is fixedly connected to the surface of the spraying
assembly, and the material mixing assembly comprises a collecting box, a feeding port, a motor, a connecting rod, blades and a filter screen. Through the arrangement of the collecting box, the feeding port, the motor, the connecting rod, the blades and the filter screen, when the device is used, the feeding port is fixed by the collecting box, a
plant nutrient is poured into the feeding port and enters the collecting box, the motor is externally connected with a power supply to drive the connecting rod to rotate, the connecting rod is connected with the blades, and the filter screen is fixedly connected with the motor. Blades are fixed on the surface of the connecting rod, the blades rotate to stir and mix the internal
water source and the
plant nutrient, and a filter screen is used for filtering foreign matters and preventing the situation that the foreign matters fall into the
water source to block the spray head when the
water source is conveyed, so that the effect of mixing the materials for
spray irrigation is achieved.
