Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a speed sprayer that is mainly used to control fruit trees and is capable of spraying a chemical solution over a wide area using the air discharged from a blower.

[Prior Art] In a speed sprayer, a chemical solution is generally sprayed from a large number of nozzles arranged in an arc facing an air discharge port provided along the circumference of the wind barrel of an axial blower, and carried on the discharge air. The spray is spread over a wide area on both sides of the aircraft, as well as above, allowing pest control work to be carried out at high speed.

When using this product to control trellis crops such as grapes, the leaves and fruits often hang down to the top of the aircraft, and the force of the discharge wind hitting the crops directly above the aircraft is too strong The leaves may completely follow the flow of the wind, like a windsock, and the medicinal solution may not adhere to the leaves. Additionally, when there is a strong tailwind, the spray may be fanned and fall on the worker. In order to eliminate this inconvenience, as described in Japanese Utility Model Publication No. 58-2223, a low-drag plate with a large number of small holes is inserted inside the upper surface of the air outlet to weaken the force of the air blown onto the upper surface. It is being done. Additionally, workers are protected with cabins and air curtains.

[Problems that the invention aims to solve] However, killing the wind with low-drag plates reduces the efficiency of the blower, and it is also necessary to replace the low-drag plates depending on the type and condition of the crop. , it is necessary to remove it, and it becomes an expensive machine due to the installation of a cabin etc.

[Means for Solving the Problems] The present invention solves the conventional problems by providing an air discharge guide plate that can freely move in and out of the air outlet part, which allows the direction of air discharge to be changed in the front and rear directions of the truck. That is.

[Example] Next, the present invention will be described in detail based on an example shown in the drawings.

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

Next, as shown in FIG. 1, guide members 6, 6 are provided with elongated holes 7 in the vertical direction at predetermined intervals on the inside of the upper part of the air outlet 4 facing the rear wall of the tank 2.
are placed on the left and right. The lower end portion of the oblong air discharge guide plate 8 having a length corresponding to the width of the upper surface of the air outlet 4 is inserted into the elongated hole 7 of the guide members 6, 6 so as to slide in the vertical direction and to move the cart 1 forward and backward. They are connected via adjusting/fixing means 9 made of bolts, wing nuts, etc., which enable swinging in the directions. Note that the air discharge guide plate 8 may be provided on both the left and right sides of the air outlet 4 and on each of the air guide bell mouths 10.

When this configuration is used for trellising crops or when there is a strong tailwind, loosen the adjustment/fixing means 9 and pull up the guide plate 8 along the guide member 6 to expose it outside the air outlet 4 and move it above the air outlet 4. The guide plate 8 is appropriately tilted backward so as to cover the area and fixed. Note that it is preferable that the nozzle 5 on the upper surface side is also adjusted to be tilted backward in response to this operation.

In this state, the upward wind is discharged diagonally backward by the guide plate 8 and blown onto the leaves of the crop from diagonally downward, so that the force of the wind is naturally weakened and the leaves are given a suitable degree of vitrification. You can also give
It is possible to improve the adhesion of the chemical solution and prevent the chemical solution from falling on the worker.

In addition, when using it for standing trees, etc., the guide plate 8
When it is not necessary, it can be lowered along the guide member 6 and housed inside the air outlet 4.

[Effects of the invention] According to the invention, one speed sprayer can be easily and reliably applied to various types of crops, and it also improves the adhesion of chemical solutions and ensures the safety of workers. This is a great contribution.
