Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a speed sprayer, and particularly to one having a spray direction changing guide above the air outlet.

Conventional technology In general, speed sprayers are mainly used for pest control work on fruit trees, and the air outlet provided along the circumference of the wind barrel of an axial blower allows the chemical solution to be spread over a wide area using the air discharged from the blower. A large number of nozzles are placed in front of the aircraft, and the chemical liquid is sprayed by the many nozzles arranged in an arc, and this sprayed chemical liquid is carried by the discharge wind and dispersed on both sides of the left and right sides of the aircraft and above, allowing high-speed pest control work to be performed. .

However, when controlling terraced crops such as grapes, the leaves and fruits often hang down to the point where they almost touch the top of the aircraft, and the discharge wind that hits the crops directly above the aircraft is so strong that the leaves are particularly affected by the wind. In some cases, the medicinal solution may not adhere to the leaves because they completely follow the flow of the wind. Also, when there is a strong tailwind,
The spray may be agitated and fall on workers.
In order to eliminate this inconvenience, a resistance plate with many small holes is inserted inside the upper surface of the air outlet to weaken the air discharged to the upper surface, and a cabin or an air curtain is used to protect the workers. ing.

Problems that the invention aims to solve: Providing resistive plates and cabins in this way not only impairs the efficiency and working capacity of the blower, but also
There is a problem in that it requires labor and time to replace or remove the resistance plate, and the provision of a cabin etc. makes the speed sprayer itself expensive.

Means for Solving the Problems In order to solve the problems, the present invention provides a plurality of low-height guide plates that cover the upper part of the air outlet and that are arranged parallel to each other and change the spray direction in the front and back direction of the aircraft. The present invention is characterized in that it is configured to include a connecting member that allows the guide plates to interlock with each other, and a member that rotates the guide plates.

Effect: Therefore, by providing a large number of spray direction change guide plates, the spray direction can be changed reliably, so a simple structure such as reducing the height of each guide plate to reduce uneven spray distribution can be used. There is work.

Embodiments Next, the present invention will be described in detail based on embodiments shown in the drawings.

As shown in FIG. 3, the speed sprayer of this embodiment has a chemical tank 2, an axial blower 3, etc. mounted on a self-propelled truck 1, and is provided with an arc-shaped opening along the cross section of the wind barrel of the blower. A large number of spray nozzles 5 are arranged at the air outlet 4.

Four mutually parallel guide plates 6 for changing the spray direction are arranged in parallel orthogonal to the longitudinal direction of the machine body so as to cover the upper part of the air outlet 4 in which the spray nozzle 5 is disposed.

These guide plates 6 are illustrated in FIGS. 1 and 2, and these guide plates 6 are constructed such that their lower ends are pivotally supported by a frame 7 and their upper ends are pivotally supported by a connecting member 8 to interlock with each other. ing. Further, as shown in FIG. 1, the frame 7 has its rear end fixed to the wind barrel of the blower 3 with bolts, and has a lever 9 that directly rotates the guide plate 6 at the rearmost end. This lever 9 has the same axis as the axis of the guide plate 6, and has a screw member 10 at its swinging end that allows the lever 9 to change the rotation angle in five steps. 10 to fix the angular position of the guide plate 6. Furthermore, in this embodiment, a connecting member (not shown) is provided so that the spray nozzle 5 interlocks with the guide plate 6.

The device that changes the spray direction in this way is a unit type, and by attaching and detaching the frame 7 to the wind barrel of the blower 3, the entire device can be installed and removed, and by increasing the number of guide plates, the height of each guide plate can be reduced. This makes it easier to work on terrace crops, and improves the distribution performance of chemical spraying.You can adjust the angle of the guide plate and spray nozzle to suit the situation without reducing the efficiency of the blower. You can work optimally together.

Effects of the Invention As described above, according to the configuration of the present invention, each guide plate is provided with a plurality of guide plates arranged parallel to each other that cover the upper part of the air outlet and change the spray direction to the front and back direction of the aircraft. By lowering the height of the sprayer, it is possible to evenly and optimally spray pesticides on trellised crops.
Effects such as being able to easily select and set the optimum spray direction according to the work situation are achieved.
