3WP-1200 spray machine is a spray machine equipped with automatic folding spray rod, which is powered by tractor.    It is convenient to move, spraying wide, spraying evenly, atomizing effect is good, high efficiency, is an ideal field crop plant protection machinery, suitable for large area of low crop spraying field.

1.Good atomization effect, spraying uniform distribution and environment friendly:This sprayer adopt the Venturi-type stirring system, independent pesticide bottle and pesticide tank cleaning device ,the spray pressure regulation system, the subsection control system, the multistage filtration system and the anti-drip device. The uniform Pesticide liquid concentration, atomization effect and spraying cover uniformity of this spray machine have reached the best,This ensures the effect of spraying, reduces the amount of pesticide used, and is more environmentally friendly

2.Wide range of spraying and easy to move on：

The sprayer is equipped with automatic hydraulic lifting of the spray bar, the spray bar folding system,When the spray rod is folded, the width of the whole machine is 2.37 meters,It is very convenient to move.The Spray rod deployable length up to 24 meters,It is a very wide range

3.The operation is simple and convenient :

The lifting and folding of the spray rod adopt the company's proprietary hydraulic control technology, which can be operated in the cockpit with one key.  When the spray rod is unfolded, it is unfolded orderly from inside to outside, and when it is folded, it is folded from outside to inside.  The operation is simple, safe and stable.

4.Safe and durable: 

The spray rod LOCKING system ，self-balancing system and spray rod end protection technology are adopted.  When the spray rod is extended and folded, the spray rod locking system will start synchronously, so that the spray rod can not swing around the center of gravity axis, and prevent the damage of the spray rod and machine tools due to the asynchronization of extension.  After the spray rod is completely opened from both sides, the two sides of the spray rod are balanced, and the center of gravity of the spray rod coincides with the center of gravity axis.  When the lock is lifted, the spray rod can swing around the center of gravity axis to reduce the influence of the shaking of the walking machine on the spray rod.  Considering THE LARGE EXTENSION LENGTH OF THE spray ROD, THE protection technology is adopted AT THE end of the spray rod, so that the end of the spray rod can automatically shrink and timely reset when it touches obstacles, which not only ensures the application effect, but also ensures the safety and durability of the spray rod and the machine.
