2. Description of the Related Art In recent years, a cultivation method using a plant growing house has been remarkably advanced and developed, but in order to obtain a more well-shaped one, a scar and no trace of insect worms, due to market demand,
Alternatively, in preparation for pests, it is necessary to frequently spray chemicals and spray water. 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.

Further, in the chemical spraying work manually performed, work unevenness is inevitable and a complete work cannot be performed. Therefore, as an apparatus for automatically traveling in the house to perform the spraying work of various liquids, for example, the actual open sho-62-
Those disclosed in Japanese Patent No. 59158 and Japanese Utility Model Laid-Open No. 21333463 have been proposed.

In Japanese Utility Model Laid-Open No. 62-59158, a guide rail is arranged in the upper part of a plant growing house along its longitudinal direction, and a guide rail having a length substantially the same as that of the guide rail is provided. The flexible liquid conducting tube is connected in an annular shape to be housed, a liquid supply port is provided at the connection part of this tube, and this is fixed at approximately the center in the longitudinal direction of the rail. A liquid sprinkler is attached to the central portion of the direction, a pair of traveling carriages that wind around an annular tube and travel inside the rails are provided, and the tow lines of the endless wire type transfer mechanism are fixed to each traveling carriage. .

Further, the one disclosed in Japanese Utility Model Application Laid-Open No. 2-1333463 is a distribution cart in which a guide rail is arranged in the upper part of a plant growing house along its longitudinal direction, and a liquid spreader is arranged on this guide rail. And the pulley carriage around which the flexible liquid guide tube is wound, and the liquid guide tube whose one end is connected to the supply port fixed at approximately the center in the longitudinal direction of the rail 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.

[0006]

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 for 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 spraying 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 in the width direction, but in this case, in order to cover the entire surface of the large cultivation area, the length in the width direction of the sprinkler pipe derived from the spray cart is increased. However, there is a problem that the liquid pressure is different between the beginning and the end of the flow path in the water sprinkling pipe, and it is difficult to uniformly spray the liquid. In addition, one guide rail contains the weight of the liquid chemical. There is a problem that the guide rail must be firmly formed because the heavy water sprinkler must be supported, and that the structure of the house itself must be solid to support the strong guide rail. That. The present invention has been made in view of such a point, and an object thereof is to provide a liquid spraying device capable of reliably spraying liquid over the entire area of a house with a simple structure.

[0008]

In order to achieve the above-mentioned object, the present invention provides traveling guide members on both sides of the upper part of a plant cultivation house along the longitudinal direction of the house, and the traveling guide members work respectively. The trolley and the adjustment trolley are movably supported, and the two trolleys for work are connected to each other by a horizontal beam arranged in a state orthogonal to the traveling direction, and a liquid guiding pipe is arranged along the horizontal beam. A plurality of lotus nozzles are fixed to the pipe, the liquid supply port is fixed so as to correspond to the arrangement surface of the traveling guide member at the center part in the longitudinal direction of the house, and the liquid guiding port supported by this liquid supply port and the work trolley The pipes are connected to each other by flexible liquid guiding tubes, and the middle part of each liquid guiding tube is wrapped around a rotary pulley that is pivotally supported by the adjustment carriage, and one end is the end of the work carriage opposite the adjustment carriage side. The other end of the tow rope fixed to the section is counter-fabricated with the adjustment carriage. Respectively connected to use truck-side end portion,
The middle part of each tow line is wrapped around the rope pulleys arranged at both ends of the travel guide member, and both tow lines are configured to be capable of synchronous tow operation with a common rotary drive source. It is characterized in that it is configured to move in synchronization.

[0009]

In the present invention, the trolleys for work which synchronously travel the traveling guide members arranged along the longitudinal direction of the house on both sides of the upper part of the plant cultivation house are connected by the lateral beams, and the liquid guiding pipes are arranged along the lateral beams. It is structured so that multiple lotus nozzles are fixed to the plant, and the chemical liquid pours into the plant from the lotus nozzle in a soft state, so that the plant is not damaged by the jet pressure of the chemical liquid and the chemical liquid sprayer. Since the weight of the house can be supported by the traveling guide members on both sides, the structure of the house itself can be simplified.

Further, in the present invention, the liquid supply port is fixed so as to correspond to the disposition surface of the traveling guide member at the substantially central portion in the longitudinal direction of the house, and the liquid supply port and the liquid guiding pipe supported by the work carriage are provided. Each is connected by a flexible liquid conducting tube,
The middle part of each liquid guide tube is wrapped around a rotary pulley that is pivotally supported by an adjustment trolley, and one end is fixed to the opposite end of the work trolley. Connected to each end of the trolley, the intermediate part of each tow line is wrapped around a rope pulley arranged at both ends of the travel guide member, and both tow lines are configured to be capable of synchronous tow operation by a common rotary drive source. Since the work carriage is configured to move synchronously by the operation of both tow lines, the chemical liquid spraying device itself for reliably spraying the chemical liquid over the entire cultivation area can be configured to be lightweight.
