Description

  The present invention relates to a recovery system for drainage and drainage (residual liquid, residual water) of a house (a building such as a vinyl house or a glass house) and a structure of a switching valve used in this system.

  Conventionally, in a house, chemicals or water is sprayed from a nozzle of a spreader or other equipment toward a crop. Then, when the spraying is finished, it is necessary to collect the chemical solution (drainage) remaining in the sprayer or the pipe (hose) or the remaining water (drainage).

  The reason for this is, for example, in the case of drainage, solidification of the residual chemical solution and clogging of piping, valves, etc. based on this solidification, or residual drainage, especially in the case of well water, algae spores remain. Since there are problems with the generation of algae, piping damage, clogging of pipes, valves, etc. based on the generation of algae, and in cold regions, there are freezing problems due to this residual drainage and residual drainage. So far (currently) individual measures have been taken at the individual level. For example, the power sprayer is rotated in the reverse direction, and the drainage or drainage is returned to the power sprayer and then returned to the tank.

  However, it has been found that the individual measures according to the current individual level are not sufficient and the effect is not effective, and the individual measures according to the individual level are However, it has been pointed out that there are problems such as cumbersome and time-consuming work because of the structure for performing drainage and drainage recovery processing (drainage and drainage recovery processing). Therefore, there is a demand for a simple and efficient structure and means for drainage water treatment (a collection system for drainage, drainage, etc.) and a switching valve structure suitable for the recovery system for drainage, drainage, etc. .

  Then, the optimum information that fulfills this demand is examined from the prior literature, and an example thereof is listed below as a plurality of documents.

  Document (1) is an invention of “Strainer cleaning device and liquid spraying device” disclosed in Japanese Patent Laid-Open No. 2000-254416, in which a liquid suction pipe connected to a strainer provided in a tank is connected to the suction side of a triple reciprocating pump, and A structure in which a discharge pipe connected to a nozzle provided in a house or barn is connected to the discharge side of a triple reciprocating pump, and heat storage means and an air chamber are provided in this discharge pipe to achieve pressure accumulation and air introduction. Then, the fluid in the liquid suction pipe is sent from the discharge pipe to the nozzle via a triple reciprocating pump, pressure accumulation and introduction of air, and the fluid is sprayed from the nozzle. The residual fluid is returned from the discharge pipe to the tank via the liquid suction pipe, and the pressure accumulation release and the introduction of air are stopped, and the fluid from the nozzle is avoided. . However, this invention is provided with a heat storage means and an air chamber to prevent pressure accumulation / release of pressure accumulation, air introduction / introduction stop, and operation of this triple reciprocating pump and spray / drainage recovery and dripping Since the structure is composed of a large number of constituent members, the structure is complicated, and there is a need to operate each of them. Further, the heat storage means, the air chamber, the triple reciprocating pump, and the motor and other components are not integrally assembled and formed, but there are problems in downsizing, ease of operation, cost reduction, etc. It is considered a thing.

  Further, Document (2) is an invention of “medical solution spraying device and chemical spraying vehicle” disclosed in Japanese Patent Application Laid-Open No. 9-24314, in which a chemical solution inhaled by a chemical solution pump connected to a chemical solution source is provided with a chemical three-way cock. A chemical liquid spraying device that leads to a nozzle through a supply passage and injects from the nozzle, and is provided with a jet pump that operates using a chemical liquid pumped from a chemical pressure pump as a driving fluid. The chemical solution remaining in the passage is sucked by a jet pump and sent to a chemical solution source. The residual chemical liquid is returned from the strainer to the chemical liquid source via the chemical liquid supply passage from the jet pump, and the fluid from the nozzle is avoided. However, the present invention has a structure for spraying or collecting drainage and avoiding dropping of the liquid via the jet pump and the chemical solution supply passage. The load applied to the jet pump is large, and it can be installed in a large place such as a house. Is considered unsuitable. In addition, the load applied to the jet pump is large, and it is considered that there is a considerable problem in efficiently eliminating the residual chemical solution.

  Reference (3) is a devised "intake control device for an internal combustion engine" disclosed in Japanese Utility Model Publication No. 61-144232. In an independent intake throttle valve, a valve shaft is provided vertically, and an accelerator lever is provided at the center of the throttle valve. The throttle lever of the throttle valve of each trachea is connected to the accelerator lever via a throttle link. However, in this device, the throttle lever and the throttle valve that opens and closes in the same opening and closing direction are operated by operating the accelerator lever through a number of throttle levers. It does not have a structure that operates and opens and closes each valve rod provided on each link and each valve having a different opening and closing direction.

  Reference (4) is a devise of "Cylinder mounting device for multi-cylinder engine" disclosed in Japanese Utility Model Publication No. 62-116138, in which a carburetor is connected to each intake port of each cylinder of the multi-cylinder engine. The intake holes of each cylinder are tilted with the inlet facing inward, and the throttle operation rods of each carburetor are formed so that they are aligned in a horizontal line. It is structured to be connected to each throttle operating rod so that it can be operated with one operating rod. However, this device also remains in the same structure as that of the reference (3), and several links are operated from one handle, and each valve rod provided on each link and each valve having a different opening and closing direction. It is not a structure that opens and closes with one touch.

One route.

  In FIG. 3, the opening / closing valve 601 of the other insertion port 600 of the switching valve 6 is closed or opened by operating the link 604 to the end position in the axial direction B and moving the handle 603 (others). The respective on-off valves 601 of the insertion port 600 and the other insertion port 600 are respectively closed, and the central on-off valve 601 provided on the side surface 6b of the main body 6a is opened). In this state, the liquid (residual liquid, residual water) remaining in any of the pipe 506 of the fine fog cooling fan 5, the nozzle 507, or the first pipe 10, the joint 11, the branch pipe 10a, etc. From the passage of the main body 6a of the switching valve, it is led to the power sprayer 3 from the other open outlet 600 through the third pipe 15 and through the suction port of the power sprayer 3, and this power This is the second route of the structure in which the waste water discharge port (remaining liquid discharge port) of the sprayer 3 passes through the sixth pipe 20 and is then returned to the tank 2 for recovery. Through this second route, approximately 100% of the remaining liquid can be recovered and effectively used. Further, the above-mentioned adverse effects caused by the residual liquid and the adverse effects of spraying the residual liquid upon re-atomization, for example, the concentrated liquid damage to the crop, the elimination of the contaminated water adverse effects, the amount of excess chemical solution added to the crop, water It may be useful to eliminate harmful effects.

  And FIG. 13 is an example which provided the nozzle 50 (an example of a spraying apparatus) in the branch pipe 10a, for example, mainly intending spraying of a chemical | medical solution. Therefore, it is an example of the spray device described above. Others are based on the above example.
