A trailed variable sprayer

Abstract

The invention discloses a traction type variable spraying machine, which comprises a tractor and a spraying machine, and the tractor and the spraying machine are connected by a connecting shaft, and the bottoms of the tractor and the spraying machine are connected by a rotating shaft There is a roller, the rotating shaft is a hollow structure, and both ends of the rotating shaft are provided with openings that communicate with the inside, the rotating shaft is rotatably connected with a sleeve, and a first threaded rod is rotatably connected in the sleeve, and the first threaded rod is rotatably connected to the sleeve. One end of the rod is provided with a bar-shaped groove, two first sliding bars are slidably connected in the bar-shaped groove, and a first spring is arranged between the two first sliding bars. The invention facilitates the replacement of the rollers of the sprayer, not only prevents the serrated rollers from damaging the normal cement road, but also prevents the rubber tires from slipping in the field; at the same time, the flow rate of the sprayer has a qualitative gear limit , so as to facilitate the user to control the amount of spraying.

Description

technical field [0001] The invention relates to the technical field of sprayers, in particular to a traction type variable sprayer. Background technique [0002] Most of the traditional orchard spraying operations in China use simple knapsack sprayers and hand-push sprayers. The knapsack sprayers use manual knapsacks to spray the fruit trees by manually pressing the rocker. The hand-push sprayer fixes the cartridge on a movable trolley, and uses a centrifugal pump to extract the liquid and spray the pesticide. The centrifugal pump is generally driven by a small gasoline engine, an AC motor or a DC motor. However, the use of knapsack sprayers and hand-push sprayers has high labor intensity and low production efficiency. For relatively large orchards, it is easy to miss the best spraying time; for this reason, technology People have developed a traction sprayer for more efficient spraying operations, but the existing traction sprayer needs to walk in the field because the tra...

Problems solved by technology

However, for knapsack sprayers and hand-push sprayers, operators use this type of sprayer with high labor intensity and low production efficiency. For relatively large orchards, it is easy to miss the best spraying time; for this reason, science and technology People have developed a trailed sprayer to perform more efficient spraying operations. However, the tractor in the prior art needs to walk in the field, and the traditional rubber tires may cause the wheels to slip, resulting in a trap. At the same time, the traditional spraying machine cannot change the amount of spraying; therefore, we propose a traction variable spraying machine to solve the above problems
