Pesticide sprayer with self-propelled spraying frame and of which height is adjustable to adapt to various crops with high or short stalks

Abstract

The invention relates to the technical field of equipment for plant protection, in particular to a pesticide sprayer with a self-propelled spraying frame and of which the height is adjustable to adaptto various crops with high or short stalks. The pesticide sprayer comprises a rack, a walking transmission device and a spraying device; a driving chamber is arranged at the upper end of the front part of the rack, and a left stand shaft frame and a right stand shaft frame are fixed to the left and right sides of the front part of the rack, and a left front walking wheel and a right front walkingwheel are installed at the left and right sides of the front part of the rack respectively; left and right pesticide boxes are arranged at the left and right sides of the lower end of the rack respectively, and thus the stability of the equipment is ensured; the chassis height of the equipment is increased through the left stand shaft frame, the right stand shaft frame, a left rear wheel frame and a right rear wheel frame, and thus the equipment can adapt to spraying of the high-stalk crops, while the crops will not be damaged; pesticide spraying operation in a wide work range can be achievedby spreading a folding arm frame, the equipment can be convenient to transport and park by folding the folding arm frame, the occupation area is reduced, and the pesticide sprayer with the self-propelled spraying frame and of which the height is adjustable to adapt to the various crops with the high or short stalks has the advantages of being high in pesticide spraying speed and efficiency, simple in structure and low in cost.

Description

technical field [0001] The application relates to the technical field of plant protection machinery, and is a self-propelled spraying machine whose height is adjustable to adapt to various tall and short crops. Background technique [0002] At present, the existing crop spraying equipment on the market is generally used in conjunction with a tractor, and is hung or pulled by the tractor. Since the ground clearance of the tractor chassis is usually only 35 cm high, the existing crop spraying equipment cannot adapt to high-stalk crops. It is easy to bruise the crops, so they cannot enter the field, resulting in uneven spraying amount, that is, the crops closer to the side ridge are sprayed more, while the crops farther away from the side ridge are sprayed less. few. In addition, most of the existing crop spraying machines are small sprayers, which have problems such as slow spraying speed and low efficiency. Usually, a small sprayer can only spray 80 mu of land per day, which...

Problems solved by technology

[0002] At present, the existing crop spraying equipment on the market is generally used in conjunction with a tractor, and is hung or pulled by the tractor. Since the ground clearance of the tractor chassis is usually only 35 cm high, the existing crop spraying equipment cannot adapt to high-stalk crops. It is easy to bruise the crops, so they cannot enter the field, resulting in uneven spraying amount, that is, the crops closer to the side ridge are sprayed more, while the crops farther away from the side ridge are sprayed less. few

In addition, most of the existing crop spraying machines are small sprayers, which have problems such as slow spraying speed and low efficiency. Usually, a small sprayer can only spray 80 mu of land per day, which cannot meet the needs of large-scale fields.
