Description

[Detailed description of the invention] [Field of industrial application] This invention uses a timer to regulate the time for spraying liquid from a nozzle head equipped with a diverter in a small-volume sprayer, and when the spraying time in a certain direction has elapsed, the nozzle By turning and dispersing in a specified direction at a desired angle of 180 degrees or less, conventionally, it is difficult to achieve uniform control due to insufficient dispersion. This invention relates to a jet head turning device for a small-volume spreader that enables uniform dispersion of water and is also easy to move, assemble, and separate.

[Conventional technology]

Conventionally, for example, the width is 3.6 to 9.0 m and the depth is 40 to 80 m.
When using a small-volume sprayer for a long, narrow, single-building greenhouse, it is difficult to evenly control the sprayed objects such as seedlings, flowers, fruits, and vegetables by simply setting the jet head at the entrance of the greenhouse. In view of this, in the center of the house,
A rotary disk is installed on which components such as a jet head consisting of a nozzle, a diffusion blower, etc., and a storage tank for storing liquids such as chemicals and water are installed, and a timer is used to regulate the spraying time of the liquid, and the spraying time in a predetermined direction is set up. After the elapsed time, by rotating the rotary disk, the nozzle head was turned in the opposite direction to the above-mentioned spraying direction, and the spray was spread evenly within the greenhouse.

[The problem that the idea aims to solve]

In the spreading means described in the prior art section, when moving the spreader from the house entrance to the center,
After moving to the center, when changing the direction of spraying, there is a high risk that the branches, stems, fruits, buds, etc. of the sprayed objects that flourish and grow inside the greenhouse will be cut or dropped, so to avoid such a situation, It is preferable to pre-set the space necessary for the passage of the spreader and for the rotation of the rotary disk, but on the other hand, setting this space forces the reduction of the area where the material to be spread is planted, making it difficult to cultivate in greenhouses. It is uneconomical from the point of view of effective use of the sprayer, and due to the space setting, as the materials to be spread within the greenhouse grow and flourish over time, the space initially set becomes narrow, and the movable rotary plate of the spreader becomes too small. In order to avoid contact with the material to be sprayed, it is difficult to move and apply the material, and in order to avoid such situations, workers quickly feel troubled and fatigued, and it is clear that their work efficiency is reduced. can be,
Moreover, when a single building or a large number of L-shaped houses are owned, there is a further problem that the work becomes difficult for the workers.

This idea was proposed in view of the above-mentioned problems, and its purpose was to regulate the spraying time using a timer in the housing attached to the small-volume sprayer, and also to control the spraying time in a certain direction. By automatically changing the spraying direction as time passes and rotating only the nozzle head, it is possible to spread evenly within a single building or an L-shaped house, and it is also easy to move, assemble, and separate the nozzle head. The present invention aims to provide a jet head turning device for a small-volume spreader.

[Means to solve the problem]

In order to achieve the above object, the jet head turning device for a small amount spreader in this invention houses a timer prime mover in a case fixed on a support or a beam in a house, and a rotary shaft rotated by the prime mover is The jet head is attached to a jet head holder that protrudes from the housing and is attached to the tip of the jet head holder so that it can be detached and tilted, while the jet head is screwed into a screw hole of a sleeve that is inserted and attached to the lower part of the rotating shaft.
The setting position of the turning angle adjuster inserted through the shaft can be adjusted with respect to the rotating shaft, and the turning angle adjuster is set on the outer wall of the casing so as to be able to come into contact with a limit switch that stops the driving of the prime mover. , when a predetermined time of about 1/2 of the total spraying time in a certain direction by the jet head set by the timer has elapsed;
The nozzle head is turned in a prescribed direction by rotating the rotation axis by a desired angle of 180 degrees or less by the operation of the timer.

[Effect]

Since this idea has the above-mentioned configuration, the first
In the embodiment, the main switch 1 on the machine frame F side is
When turned on, the compressor C is driven by starting the prime mover M, and the compressed air generated by the exhaust gas passes through the air pipe 19 and reaches the nozzle N of the jet head J, and the nozzle cap 3
At this time, the ejection part of the nozzle N is in a negative pressure state under high-speed vortex flow, so the liquid in the storage tank T rises in the suction pipe 9 and the silicone pipe 11, and the flow in the nozzle N increases. Nozzle cap 3 via hole n ₀
0, at which point it mixes with compressed air, becomes a mist, and is sprayed toward the object to be sprayed (spraying time from nozzle N is determined by timer 3). 3), the timer 21 turns on and the prime mover 1
4 is activated and rotates the rotating shaft 15, so that the jet head J, which is integral with the squirrel, also rotates in the same direction at the same time, and when it has rotated by a desired angle of 180 degrees or less,
When the turning angle adjuster 17 attached to the sleeve _g2 comes into contact with the limit switch 20, the prime mover 14
The drive of the spray head J is stopped, so that the spray head J is stopped at a position rotated by a predetermined desired angle, and the jet head J is automatically turned to a direction different from that before, while the spraying operation is still continued. In this way, when the spraying time over the desired angle range from the jet head J ends, the timer 3 is activated, the drive of the prime mover M is stopped, and the spraying operation is completed. Thus, the setting position of the turning angle adjuster 17 on the rotating shaft 15 is adjusted by the sleeve g ₂ ,
By appropriately changing the rotation angle of the rotating shaft 15 through the nut _g3 , the spraying range within the greenhouse can be adjusted.

In addition, even when turning the jet head J, the silicon tube 1
Since the suction pipe 9 connected to the storage tank T is loosely penetrated through the lid 10 of the storage tank T, the suction pipe 9 rotates.
There is no risk that the silicon tube 11 will be twisted, and since the air supply pipe 19 is long, it will not be twisted even when the jet head J is turned.

In the second embodiment, the jet head receiver 16 is connected to the beam 25 ₂
In the third embodiment, the jet head receiver 16 can be moved and set in the horizontal direction via the clamping piece 26 along the horizontal direction, and in the third embodiment, the jet head receiver 16 can be moved and set in the vertical direction using the clamping piece 28 with respect to the beam ₂₅₃ . It is configurable and convenient for operators to handle.

〔effect〕

According to this invention, when approximately 1/2 of the total spraying time has elapsed, which is set in advance by a timer stored in a case fixed to a support or a beam in the house, the timer activates and the sprayer is rotated via the prime mover. axis
By rotating the nozzle head to a desired angle of 180 degrees or less, only the jet head can be turned in the desired direction to spray liquids such as chemicals or water onto seedlings, flowers, vegetables, fruits, etc. planted in the greenhouse. It is possible to spray the objects evenly, and when changing the direction of spraying, only the jet head supported by the rotating shaft is turned. Therefore, the jet head can be sprayed evenly by simply setting a small space between the covered objects that are flourishing and growing in the greenhouse. In addition, there is no need to set the time required for the rotation of the jet head in advance, and the acreage can be reduced. It doesn't have to be reduced. In addition, the jet head is removably and tiltably attached to the jet head receiver at the tip of the rotating shaft, so the operator can easily replace or clean the jet head or adjust the spraying direction as necessary. The turning angle adjuster is inserted into the screw hole of the sleeve to be fitted and put on.
The setting position with respect to the rotating shaft can be adjusted, and the turning angle adjuster is placed so as to be able to come into contact with the limit switch that stops the prime mover, so that the rotation angle of the rotating shaft rotated by the prime mover can be arbitrarily selected. It can be easily adapted to the cropping situation of the material to be sprayed in the greenhouse, which can further improve the spraying effect, and it is extremely easy to adjust the setting position without any complication, and it is small and lightweight, making it easy to use in greenhouses. When installing at 1/2 of the depth of the greenhouse, it can be installed without entering the greenhouse, and it will not damage the crops.
It is also possible to set it easily.

In the second and third embodiments, by removing the casing from the beam, it is easier to move and set up inside and outside the house, and it is also easy to organize and store in a warehouse or house when not in use. It is convenient and has practical benefits such as ease of handling for workers.

Furthermore, in the third embodiment, since the nozzle head rotates in the vertical direction, the smoke ejected from the nozzle at the time of the nozzle is sprayed toward the passage, so that it directly hits the crops.
However, it can be used with confidence, especially in the case of flowers whose commercial value decreases due to contamination.
