[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid spraying device which automatically travels in a plant growing house such as a horticultural house to spray a chemical solution or water.

[0002]

2. Description of the Related Art In recent years, the cultivation method using a plant growing house has shown remarkable progress and development.
Alternatively, in preparation for pests, it is necessary to spray the chemical solution and spray water frequently. However, the environment in which the chemical solution is sprayed in a high-temperature house is extremely bad, and since it is hermetically sealed, the worker may inhale the chemical solution, which directly impairs health. In addition, in the chemical liquid spraying operation performed manually, unevenness inevitably occurs, and a complete operation cannot be performed.

[0003] Therefore, conventionally, as an apparatus which can automatically run in a house to automatically spray various liquids, for example, Japanese Utility Model Laid-Open No. 62-59158 and Japanese Utility Model Laid-Open No. 2-13346.
The one disclosed in Japanese Patent No. 3 has been proposed. 62
In the one disclosed in Japanese Patent No. 59158, a guide rail is arranged on the upper part of the plant growing house along the longitudinal direction thereof, and a flexible liquid guiding tube having substantially the same length as the guide rail is annularly arranged in the guide rail. The tube is connected and stored in the tube, a liquid supply port is provided at the connection part of this tube, and this is fixed to approximately the center in the longitudinal direction of the rail. It is configured such that a vessel is attached thereto, a pair of traveling carriages traveling around the rail by winding an annular tube are provided, and a tow line of an endless wire type transfer mechanism is fixed to each traveling carriage.

Further, the one disclosed in Japanese Utility Model Laid-Open No. 2-133463 has a guide rail arranged on the upper part of a plant growing house along the longitudinal direction thereof, and a liquid spreader is arranged on the guide rail. , And a pulley carriage around which the flexible liquid guide tube is wound, and one end of which is connected to a supply port fixed to the center of the rail in the longitudinal direction is wound around the hose pulley of the pulley carriage. After that, it was connected to the liquid spreader fixed to the spray cart, the pulley cart was equipped with a pair of tow rope pulleys, and the first tow rope with one end fixed was wound around one rope pulley, the drive motor, and the direction change pulley in order. After that, the other end of the first tow rope is fixed to one end of the spray truck, and the second tow rope fixed to the other end of the spray truck is fixed to the pulley truck. Only wound on the pulley has a structure of arranging the tensioning mechanism to the other end of the second traction rope.

[0005]

However, in the former prior art, the endlessly formed annular liquid guiding tube is wound around a pair of traveling carriages, and the pair of traveling carriages has a tow cable of an endless wire type transfer mechanism. By fixing the, by applying a tension to the liquid guide tube to reciprocate in the guide rail while maintaining the distance between the pair of traveling carriages, it was possible to move the liquid spreader over the entire rail length, In a house having a large work area with a narrow work area that can be covered by one liquid sprayer, a plurality of liquid sprayers must be installed side by side. When multiple liquid spraying devices are installed side by side, it is necessary to arrange the drive vehicle driving motors for each liquid spraying device, which increases costs and is supported by the roof of the house. However, there is a problem in that the structure of the house itself must be strengthened because the weight of the house increases.

On the other hand, in the latter liquid spraying device, the spraying trolley supporting the horizontal spray pipe in a state orthogonal to the traveling direction is moved only within the range of the rails arranged along the longitudinal direction of the plant growing house. In this case, the liquid is sprayed in a wide range, but in this case, in order to cover the entire surface of a large cultivation area, the length of the sprinkling pipe derived from the spray cart must be increased in the width direction. However, there is a problem that the liquid pressure is different between the beginning and the end of the flow passage in the water spray pipe, and it is difficult to uniformly spray the liquid. There is a problem that the structure must be strong. Further, in a cultivated plant or the like having a high height, there is a problem that the sprinkling pipe damages the cultivated plant or suppresses upward growth. The present invention has been made in view of such points, Howe
It is an object of the present invention to reduce the weight supported by the ceiling part of a soot and to be able to process an entire house having a large cultivation area with a liquid spraying device having a simple structure.
