Description

  The present invention relates to a low-pressure spray device, and more specifically, when cultivating horticultural crops in a house, it is possible to automatically supply water, pesticides and the like without artificially supplying labor costs, etc. The present invention relates to a low-pressure spraying apparatus capable of automatically adjusting a room temperature and humidity maintenance in a house by fluid ejecting means as well as saving.

  In general, when cultivating crops in a greenhouse or the like, the crops are placed at an appropriate position per cultivation area for the purpose of spraying water, agricultural chemicals, liquid fertilizers, irrigation, etc. (hereinafter referred to as “water”). Although a sprinkler is provided and used, in the conventional case, when supplying water or the like using the sprinkler, there are many problems as described below, and this correction is urgent.

  As an example, there is one described in Patent Document 1 below, for example.

  As shown in FIG. 4, the agricultural sprinkler dedicated check valve described in Patent Document 1 below is a pipe having a female threaded portion 3 and a male threaded portion 3 ′ at both ends in configuring the agricultural sprinkler dedicated check valve 1. The body 2 is formed so that the normal sprinkler 11 and the supply pipe 12 are connected to each other, and a shielding plate 4 is formed inside the tube body 2 to constitute a check means. An opening / closing hole 5 is drilled on the shielding plate 4, and an opening / closing plate 6 is attached to and detached from the opening / closing hole 5. A shaft rod 7 is provided on the opening / closing plate 6 and a spring 8 is elastically provided. A fixed plate 9 is coupled to the tip, and a filter plate 10 is coupled to the shaft rod 7.

  In the agricultural sprinkler dedicated check valve described in Patent Document 1, the water supply pressure of the supply pipe 12 pushes the opening / closing plate 6 in the traveling direction, and the opening / closing plate 6 is detached from the opening / closing hole 5 to open the opening / closing hole 5. At this time, the opening / closing plate 6 is separated from the opening / closing hole 5 with appropriate elasticity by the spring 8 on the shaft 7 and is kept open to supply water.

  That is, in the one described in Patent Document 1 below, it is necessary to provide an elastic means such as the spring 8 in order to supply water, and the spring 8 causes a failure when its elastic force is reduced. There was a problem that maintenance and repairs were forced due to frequent failures.

  Another example is a fruit tree sprinkler head described in Patent Document 2 below.

  As shown in FIG. 5, the following Patent Document 2 forms an injection pipe 1 a on the side of a sprinkler head main body 1 attached to the upper end of a water pipe 10, and a rotary rod 2 with a head upper end central axis 1 b as a rotation axis. Equipped with a spring 4 attached to the main body 1 and rotated and sprayed by water pressure, the nozzle 6 screwed into the tip end side of the injection pipe 1a is cut downward. The lower end of the notch 6b is inclined and the screw groove 7a is recessed on one side of the tightening screw 7 covered with the lower end connecting pipe 5 of the main body 1, and the brake plate 8 is fitted into the screw groove 7a. A fixing screw 9 is fitted on the outside so that the degree of friction of the brake plate 8 can be adjusted, and the rotating guide 2 is equipped with a direction guide plate 3.

  However, the fruit tree sprinkler head described in the following Patent Document 2 also requires a spring, and has a disadvantage that failures frequently occur when the elastic force of the spring decreases.

  In other words, conventional sprinklers that inject agricultural water into agricultural crops, due to the provision of elastic means such as springs that are crimped by the water pressure of agricultural water, cause malfunction due to a decrease in the elastic coefficient of the elastic means when used for a long time. As a matter of course, the lifespan of the sprinklers is reduced, and if the elastic means malfunctions, disassembly and assembly are forced, but it is difficult to disassemble and reassemble, so anyone can easily repair the sprinkler. There were many problems, such as being unable to do so.
