Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a spraying device for spraying water, an exterminating liquid or the like on a plant to be grown in a cultivation facility for growing the plant by efficiently collecting sunlight in a greenhouse such as a greenhouse or a glass house.

[0002]

[Prior Art]

 In a greenhouse such as a greenhouse or a glass house, the larger the cultivation facility is, the larger the working hours and labor that are devoted to spraying water and exterminating liquid are. In order to reduce the working conditions in such cultivation facilities, rails have been installed horizontally over the entire length of greenhouses such as greenhouses, and this rail is used as a single track for self-propelled water spraying or spraying. There is already known a sprinkling device that automatically sprinkles water, exterminating liquid, etc. on a cultivated product from the length of a horizontally long boom directly connected to the sprinkler by reciprocating the desired spreader.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned prior art, a structure is adopted in which a traveling wheel mounted on a spreader is engaged with a rail having a circular cross section by point contact to suspend the spreader. With such a structure, when the boom directly connected to the spreader receives an external force, or the left and right balance is lost due to a slight disagreement in the boom equilibrium relationship, the boom will move to the left or right around the engagement point of the running wheels. May swing to. If this swaying to the left and right occurs during reciprocating motion, that is, during water spraying or spraying of the exterminating liquid, the boom collides with the crops such as vegetables, flowers, fruits, etc., causing damage, or sprinkling or spraying the exterminating liquid over the entire area. It will not be evenly distributed across the ground and will adversely affect development. Further, when the boom swings violently, the tension applied to the rail may be further loaded, which may cause deterioration of durability.

The present invention has been made in view of the above conventional circumstances, and an object of the present invention is to provide a spraying device for a greenhouse in which a boom does not swing left and right.

[0005]

[Means for Solving the Problems]

 The technical means taken to achieve the above object is to form a vertical cross-sectional shape of a rail into a quadrangle with a pair of diagonal positions on a vertical line, and to engage the rail with a traveling wheel to suspend the spreader. Is formed into a shape having a V-shaped groove in side view with a rolling surface that makes surface contact with the chevron surface of the upper half of the rail.

[0006]

[Action]

 According to the above technical means, the spreader is suspended in the vertical state by the surface contact between the chevron surface of the upper half of the rail and the rolling surface of the traveling wheel having the V-shaped groove in side view. To do.

[0007]

[Effect of the device]

 As described above, the present invention is configured so that the rails and the traveling wheels guided by the rails are in surface contact with each other so that the spreader can travel in the vertical state as much as possible. Even if a load force is applied to the horizontally long boom that is directly connected, the surface engagement between the rail and the running wheel acts as a resistance to the swing of the boom and the boom immediately returns to the vertical state. Optimal spraying that eliminates the impact of spraying, uneven spraying of water / spray, and increased load on the rail due to continuous rocking motion, not only eliminating the spraying effort but also not adversely affecting the crops and the equipment itself. A device can be provided. In addition, the carrier of the sprinkler supply hose and the extermination liquid supply hose connected to the sprayer can also follow the same rail with the same driven wheel shape as the running wheel, and the hose can be swung quickly. You can stop at. Therefore, it is possible to achieve an advantage that even if the user accidentally hooks his foot on the hose, the influence on the apparatus main body is small.
