a spraying machine

Abstract

The invention relates to a spraying machine, which includes a cab, a cab lifting device, a variable wheel base assembly, a chassis power system, a spraying frame lifting device, a spray rod assembly, a medicine box assembly, a wheel assembly, and a vehicle hydraulic system , the cab lifting device includes the cab upper parallel rod, the cab lifting cylinder, the cab lateral stabilizer bar, the cab lifting fixed frame, the cab lower parallel rod and the cab lifting mobile frame; the cab upper parallel rod and the cab lower The parallel rods are two rods of equal length, one end of which is hinged with the cab's lifting and fixing frame, and the other end is hinged with the cab's lifting and moving frame; Hinged, the cab can be raised and lowered by the expansion and contraction of the oil cylinder. The invention is a hydraulic self-propelled type, and the wheel base can be adjusted to adapt to the ridge distance of different crops, and can apply pesticides in a large area, and the height of the spray boom can be adjusted according to the height change of the crops, and the steering is flexible.

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.
