Spraying machine

Abstract

The invention relates to a spraying machine. The spraying machine comprises a cab, a cab lifting device, a variable-tread assembly, a chassis power system, a spraying frame lifting device, a spraying rod assembly, a pesticide box assembly, a wheel assembly and a whole machine hydraulic system, wherein the cab lifting device comprises upper cab parallel rods, cab lifting cylinders, transverse cab stabilizing rods, a fixed cab lifting frame, lower cab parallel rods and a movable cab lifting frame; the upper cab parallel rods and the lower cab parallel rods are equal in length, one end of each parallel rod is hinged to the fixed cab lifting frame, and the other end of each parallel rod is hinged to the movable cab lifting frame; one end of each cab lifting cylinder is hinged to the corresponding upper cab parallel rod, the other end is hinged to the fixed cab lifting frame, and a cab is lifted and lowered under the telescopic action of the cylinders. The spraying machine adopts a hydraulic self-propelling manner, the tread can be adjusted to adapt to ridging spaces of different crops, large-area pesticide application can be performed, the height of a spraying rod can be adjusted according to crop height change, and flexible steering is realized.

Description

technical field [0001] The invention relates to the field of agricultural vehicles, more specifically, to a spraying machine. Background technique [0002] In recent years, due to the adjustment of agricultural planting structure and scale, coupled with the fact that there are more plains in the northern region, large-scale crop planting has become popular, and most of the crops planted in the north are high-stalk crops such as corn and sorghum. Pesticides need to be sprayed. The traditional artificial spraying technology can no longer meet the requirements due to the shortcomings of limited spraying area and harmful to human health. The research and development of spraying machines is very necessary. At present, most of the sprayers on the market are traction-type, with small ground clearance, and cannot adjust the wheelbase according to the ridge spacing of different crops. They have poor adaptability to the growth height of crops and there are too many seedlings when spra...

[0002] In recent years, due to the adjustment of agricultural planting structure and scale, coupled with the fact that there are more plains in the northern region, large-scale crop planting has become popular, and most of the crops planted in the north are high-stalk crops such as corn and sorghum. Pesticides need to be sprayed. The traditional artificial spraying technology can no longer meet the requirements due to the limited application area and harmful to human health. The research and development of spraying machines is very necessary.

At present, most of the sprayers on the market are traction-type, with small ground clearance, and cannot adjust the wheelbase according to the ridge spacing of different crops. They have poor adaptability to the growth height of crops and there are too many seedlings when spraying. phenomenon, while the cost of sprayers developed abroad is not suitable for my country's national conditions.
