Abstract

PURPOSE:To enable an intended spray amount to be obtained and a spray condition to be set easily by providing jet orifices at different spray angles and different types of spray plate, then changing the spray angle to coincide with the outlet of a base jet orifice, and allowing a liquid to spout only through a selected jet orifice. CONSTITUTION:A spray nozzle 2 is mounted on a self-propelled spray machine which moves between furrows, spraying water or a chemical to a crop on the furrow. This spray nozzle 2 has jet orifices 6 at different spray angles, each jet orifice having different types of spray plate 7. The spray angle is changed so that it coincides with the outlet of a base spray orifice 5. Thus the liquid is allowed to spout only through a selected spray orifice 6. Consequently, the liquid is sprayed only from the coincided spray orifice 6 simply by selecting the spray orifice 6 with the spray plate for an intended spray amount and matching the spray orifice 6 with the position of the base spray orifice 5, while the spray orifices 6 at the other positions remain closed. In addition, the nozzle 2 is freely rotatable, and therefore, can spray the liquid within a vertical spray range of about 70 deg. only by rotating the spray orifice 6 to be used to an intended angle.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spray nozzle of a self-propelled sprayer for spraying water or a chemical solution on a crop in a ridge while moving between the ridges.

[0002]

2. Description of the Related Art As shown in FIG. 10, a conventional spray nozzle of a self-propelled sprayer has a structure in which a boom 3 ', 3'consisting of two right and left stands upright in front of the self-propelled sprayer. A spray nozzle 2'having one injection port 6'is attached to the left and right booms at the same upper and lower positions.
It was possible to incline (about 30 °), and one spray plate was attached inside the spray port, and when the spray amount was changed, this spray plate was replaced.

[0003]

However, in the conventional spray nozzle, it is necessary to remove the cap of the injection port and replace the injection plate with another type each time the spray amount is changed, which is troublesome. It was such work. Also, when changing the spray height, the mounting location must be changed up and down, but the height can be adjusted, but the spray angle is almost the same because the vertical rotation angle of the spray nozzle is small (Y °). It can only be sprayed horizontally. In the present invention, a spray nozzle attached to a self-propelled sprayer is a spray nozzle whose spray amount and spray angle can be easily adjusted.

[0004]

The problems to be solved by the present invention are as described above, and the means for solving the problems will be described below. A spray nozzle attached to a self-propelled sprayer that moves between ridges while spraying water or chemicals on the ridge crop, has several nozzles with different spray angles, and each nozzle has a different type of spray plate. Equipped with a spray nozzle that changes the spray angle.
It is configured to spray only from the selected nozzle by matching the outlet of the nozzle.

The problems to be solved by the present invention and the means for solving the problems are as described above. Next, the structure of the embodiments according to the present invention will be described with reference to the accompanying drawings. 1 is a perspective view of the overall structure of the self-propelled sprayer, FIG. 2 is a perspective view of the self-propelled sprayer A,
3 is a front view of the multi-spout type spray nozzle 2 attached to the boom 3, FIG. 4 is a side view of the same, and FIG. 5 is a multi-spout type spray nozzle 2
6 is a side sectional view of the same, FIG. 7 is a front view showing a spraying work according to this embodiment on a standing tree, FIG. 8 is a front view showing a high-angle spraying work, and FIG. 9 is a low-angle view. It is a front view which shows the spraying work of.

First, the overall structure of the self-propelled spraying machine of the present invention will be described with reference to FIG. The self-propelled sprayer A is mounted on the trolley C in the headway B2 in the headland, and the winch D is installed.
When the wire is pulled by the wire and reaches the target ridge, it is unloaded from the carriage C and travels on the traveling path B1 between the ridges.
While the front and rear wheels are driven by the built-in battery to run, the spray nozzle 1 sprays water, chemicals, and the like. A reversing pile F is erected at the end of the traveling path B1 between the ridges, and when the front end of the self-propelled sprayer A is pressed, the vehicle body is reversed by a sensor reaction. Then, the vehicle travels back along the traveling path B1, is mounted on the carriage C on the traveling path B2 in the headland, and moves to the next ridge. In addition, a hose is connected to the hose reel E2 of the base machine E from the self-propelled sprayer A, and the dynamic jet E1 in the base machine E sends water or a drug to the hose from a liquid (medicine) tank (not shown). To liquidate. Further, the hose reel E2 is equipped with a motor for driving the reel, and the hose is paid out or wound up while the self-propelled sprayer A is moving.

The multi-spout type spray nozzle 2 of the present invention is attached to a boom 3 fixed by a nozzle holder 4 projecting from the front part of a self-propelled sprayer A as shown in FIGS.
The boom 3 is attached to the boom 3 by mounting a fixture 5 which is slidable up and down, that is, the vertical position of which can be adjusted, and one multi-spout type spray nozzle 2 is provided in front of and behind the fixture 5.
Is rotatably attached so that it can be sprayed to the left and right simultaneously from one place.

The multi-spout type spray nozzle 2 has a plurality of spray ports 6 as shown in FIG.
It is rotatable around the base injection port 5. In this embodiment, there are three nozzles. As shown in FIGS. 5 and 6, different spray plates 7 are inserted into the spray ports 6 of one multi-spout type spray nozzle 2 in order to adjust the spray amount. Some spray plates 7 have holes of various sizes and shapes, and the amount of spray is adjusted by exchanging these holes. By the way, in FIGS. 5 and 6, 8 is a vortex chamber, and 9 is
Is a cap, 10 is a packing, and 11 is a core, and the arrows in FIG. 6 indicate the flow of the liquid to be sprayed. That is, the liquid filled in the nozzle enters the swirl chamber through the spiral hole formed on the injection port side of the core 11, passes through the hole of the injection plate 7, and is sprayed from the injection port 6. There is.

Further, as shown in FIG. 3, the multi-spout type spray nozzle 2 vertically moves about X ° (about 35 °) with the base spray port 5 as a rotation axis.
Rotation is possible, and spraying is possible within a total width of 70 ° vertically. By taking a large X °, any of the nozzles 6 can be rotated to a horizontal position, and spraying at a high angle or a low angle by the nozzles is also possible. Therefore, even if the ejection plates are not detached one by one, by rotating the ejection port 6 having the ideal ejection plate 7 to the ideal spray angle, the other ejection ports do not coincide with the base ejection port 5, so that the valve is opened. It is closed and not sprayed. Then, at a position outside the angle X °, the angles at which the sprays from all the injection ports 6 stop are provided in three equal positions.

With this configuration, for example,
Among the nozzles, 6a, 6b, 6
As shown in FIG. 7, in a spraying operation for a standing tree whose upper part is growing, as shown in FIG. By this, it is possible to apply an ideal spray to each standing tree.

Further, since the selection range of the spray angle is large,
As shown in FIG. 8, it is possible to spray a tall tree at a high angle and spray a seedling having a short length on a flat floor as shown in FIG. Since the spray outlet of the base injection port 5 is opened in only one direction, the spray is made only from the injection port 6 aligned with this direction. It is not sprayed from the nozzle 6 which does not match the position of the nozzle of the base nozzle 5.

[0012]

The present invention having the above-described structure has the following effects. That is, since a plurality of spray nozzles are provided in the multi-spout type spray nozzle, and spray plates with different spray amounts are respectively attached, when adjusting the spray amount according to the growing condition of the crop, remove the spray holes one by one to achieve the target spray. It does not require time and effort to replace the spray plate with a desired amount, and only by selecting a spray port having a spray plate with a desired spray amount and aligning it with the position of the base spray port 5, spraying is performed only on the matched spray port, and The two nozzles in the position are in a closed state. This makes it possible to obtain the target spray amount.

The nozzle is rotatable, and spraying from the nozzle 6 within a width of 70 ° in the vertical direction is possible only by rotating the nozzle to be used to a desired angle. Further, the angle of the spray direction can be changed within the range of 70 degrees. Further, if the angle deviates from the angle of 70 °, it is possible to stop the spray from all the nozzles. Further, it is possible to obtain a desired spray angle, and thus it is possible to easily set an ideal spray state.
