Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for spraying liquid chemicals and the like in a horticultural house, and in particular, a water spray pipe having a nozzle attached thereto is suspended in the house and vertically moved while rotating the water spray pipe. As a result, it is possible to automatically and reliably spray the chemical liquid, water, etc. over the circumferential direction and the vertical direction.

2. Description of the Related Art Recently, cultivation methods using horticultural greenhouses have made remarkable progress, but due to market demand, in order to obtain better-shaped ones and those without scratches or worm marks,
Alternatively, in preparation for pests, it is necessary to frequently spray chemicals and spray water.

However, the chemical spraying work in a high-temperature house has a very bad environment, and since it is hermetically sealed, the worker sucks the chemical, which causes a direct harm to health. Furthermore, in the chemical spraying work performed manually, uneven work is inevitable, and it is impossible to expect complete work. Further, the time required for the spraying work is long and the physical burden is extremely heavy because of the heavy labor. Therefore, inconveniences occur such that the time required for other various operations is inevitably limited.

For this reason, various mechanical devices have been provided which automatically run in a house to automatically perform various spraying operations. For example, there is one in which a water guiding tube is hung at a constant interval via a hanging ring on a wire installed in the house to hang the water guiding tube in a loop shape, and the water guiding tube is run while being stretched.

[0005]

However, according to the above-mentioned automatic spraying device, the water guiding tube hangs down, and it becomes difficult to spray the water because it does not reach the end of the house. On the other hand, the hanging water guiding tube interferes with the gardening work. There is a drawback in that it is not uncommon for an operator to damage the hanging water guiding tube by hooking it with a work tool.

Further, the automatic spraying device has a high installation cost and has not come into widespread use. Further, there is unevenness in spraying, and there is a surface where the spraying effect is higher when the spraying is done manually by human power, which makes it less meaningful as a mechanical device. Further, in the case of spraying a chemical solution, particularly disinfection work, it is necessary to spray evenly to the front and back of leaves of a cultivated crop, but with a conventional mechanical device, it is only sprayed, and it is not possible to spray to the back side of leaves.

In view of the above, the present invention solves the above drawbacks and suspends a sprinkler tube provided with a nozzle in a horticultural house, and vertically moves while rotating the sprinkler tube, so that the entire circumference and the vertical direction are covered. (EN) A method and a device for spraying a chemical solution or the like in a horticultural house that can automatically and evenly spray the chemical solution, water and the like.

EXAMPLES A method for spraying a chemical solution or the like in a horticultural house according to the present invention is such that while supplying the chemical solution or water to a water spray tube having a plurality of nozzles in the longitudinal direction, the spray tube is rotated in the circumferential direction and moved up and down. It is characterized by spraying the medicinal solution or water over the entire front and back of the leaves of the crop.

Specifically, this is rotated in the circumferential direction while supplying the chemical liquid or water to the sprinkler pipe arranged in parallel with the ridges in the horticultural house, and is vertically moved to a predetermined interval in the longitudinal direction of the sprinkler pipe. The chemical solution or water is sprayed from a plurality of nozzles provided in 1. to spray the chemical solution or water over the entire front and back of the leaves of the crop.

An embodiment of a spraying device for carrying out the above method will be described with reference to the drawings. FIG. 1 is a front view of a horticultural house, and FIG. 2 is a plan view of the interior thereof. As shown in the drawing, a connecting rod 2 made of a tubular body is arranged orthogonal to the ridge 1 at the base end of the ridge 1 and the ridge 1 In parallel with each other, the water spray pipes 4 are arranged in the grooves 3 between the ridges or alternately, and one ends of the water spray pipes 4 are rotatably and orthogonally supported by the connecting rods 2, respectively. That is, as shown in FIG. 3, the bearings 5 are fixed to the connecting rod 2 at regular intervals, and the water sprinkling pipe 4 is rotatably supported in the circumferential direction via the bearings 5. As shown in FIG. 5, the bearing 5 rotatably supports the water spray pipe 4 on the bearing 6 and is fixed to the connecting rod 2 by the U bolt 5a and the nut 5b.

As shown in FIG. 3, an extendable water pipe 7 is connected to one end of the connecting rod 2 and the other end is closed. The water supply pipe 7 is connected to a pump 8 and a tank 8a that pressure-feed the chemical liquid or water. An appropriate water supply pipe 10 is connected to one end of the water spray pipe 4 via a rotary joint 9, and the water supply pipe 10 is connected to a connecting rod 2 via a solenoid valve 11. Further, a plurality of nozzles 12 are attached to the sprinkling pipe 4 at predetermined intervals in the longitudinal direction.

Further, as shown in FIG. 3, a plurality of drums 13 are fixed to the sprinkling pipe 4 at regular intervals in the longitudinal direction, and the other end of the wire 14 wound by connecting one end to the drum 13 is horticultural. It is connected to the ceiling structure 15 of the house. The ceiling structure 15 is made of a wire stretched between columns.
Further, sprockets 16 are fixed near the drum 13 at one end of the sprinkling pipe 4, and an endless chain 17 is wound around the sprockets 16.

Then, as shown in FIG. 4, a sprocket 18 is fixed to the center of the sprinkler pipe 4 in the substantially central portion, and a chain 19 is wound around the sprocket 18. One end of the chain 19 is connected to a motor block 20 suspended from the ceiling structure 15, and the other end is connected to a winch drum 21 of the chain 19 so that the chain 19 can be wound and unwound.

Therefore, the plurality of sprinkling pipes 4 are rotatably supported by the connecting rods 2 by endless chains, and are suspended from the ceiling structure 15 by the wires 14, and
The chain 19 can move up and down. It should be noted that the endless chain 17 has sprocket wheels 23, 23 stretchably supported by springs 22 at both ends thereof.

Next, the operation of the above embodiment will be described. With the connecting rod 2 and the sprinkler pipe 4 landing in the house, the pump 8 is driven to pump the chemical or water from the water pipe 7 to the connecting rod 2. Then, from the water supply pipe 10 to the sprinkler pipe 4 via the rotary joint 9.
And the chemical liquid or water is ejected from the nozzle 12. The ejection of the chemical liquid or water is controlled by operating the opening / closing of the solenoid valve 11.

Therefore, when the motor block 20 is started to rotate the winch drum 21 and the chain 19 is wound up, the sprinkler pipe 4 having the sprocket 18 rises while rotating, and the rotation causes the endless chain 17 and the sprocket 16 to rotate. The other sprinkler pipes 4 are rotated in the same direction via the connecting rods 2, and all the sprinkler pipes 4 are integrally raised via the connecting rods 2, and thus the connecting rods 2 and the plurality of sprinkler pipes 4 are raised while being parallel to the ground. To do. The wire 14 is wound around the drum 13 as the sprinkling pipe 4 rotates and rises.

Therefore, as shown in FIG. 7, the nozzle 1
As 2 rises from the ground while rotating in the circumferential direction of the sprinkling pipes 4, the spouting liquid 26 spouts radially around each sprinkling pipe 4, and therefore the crop 27 cultivated in the ridge 1
It goes without saying that the front and back of the leaves are evenly distributed over the entire surface.

Incidentally, in this spraying, when the rotations of the respective water spray pipes 4 are alternately rotated in the opposite directions, that is, as shown in FIG. 6, the pulley belts 24 are laid between the adjacent pulleys 25. Thus, if every other one of the pulleys 25 for interlocking the sprinkling pipes 4 is rotated in the forward direction and the other is rotated in the reverse direction, from the sprinkling pipes 4 rotating in the forward direction, from above the crop, From the sprinkling pipes 4 which rotate in the opposite direction, the spouts can be spouted from below each of the crops, and more effective spraying can be performed.

The connecting rod 2 and the sprinkling pipe 4 have a predetermined height,
That is, when it moves up near the ceiling structure 15, the driving of the motor block 20 is stopped. When spraying the chemical liquid or water again, the motor block 20 is driven to rotate in the reverse direction and the chain 19 is gradually fed out, and the water spray pipe 4 having the sprocket 18 rotates, and the other water spray pipes 4 interlock with each other to reverse the direction. It rotates and the wire 14 is paid out from the drum 13. When the connecting rod 2 and the sprinkling pipe 4 land, the driving of the motor block 20 is stopped. By repeating this operation a required number of times, desired chemical solution spraying or the like is automatically performed. When the connecting rod 2 and the sprinkler pipe 4 land,
It is also possible to provide a limit switch that operates when reaching the ceiling structure 15 to automatically stop the driving of the motor block 20.
