[0014] Next, embodiments of the present invention will be described with reference to the attached drawings to facilitate understanding of the present invention. Note that parts not relevant to the description may be omitted from the drawings.

[0015] First Embodiment A chemical spraying device 10 according to a first embodiment of the present invention is capable of spraying liquid chemicals such as pesticides inside an agricultural greenhouse 12 (see FIG. 1) for cultivating vegetables and fruits. The agricultural greenhouse 12 has a longitudinal length of, for example, 20 to 100 m, and as shown in FIG. 2, is composed of a structural material 122 that serves as a framework, and a covering material 124 such as a synthetic resin film. As shown in FIG. 1, the chemical spraying device 10 includes a guide member 20, a sprayer 30, a hose 40, an electric hose winder 50, a pump 60, and a chemical tank 70.

[0016] The guide member 20 is a rail that is disposed in the center of the interior of the agricultural house 12 when viewed from the front, and extends in one direction along the longitudinal direction of the agricultural house 12. The guide members 20 are attached via hanging members 22 fixed at intervals to the structural members 122 constituting the agricultural greenhouse 12. The height position at which the guide members 20 are attached is preferably within a range where a worker can attach the sprayer 30 without using a stepladder or the like. The hanging member 22 is attached to the structural member 122 using a U-bolt.

[0017] The dispenser 30 is movably installed while suspended from the guide member 20, and can dispense the medicine. As shown in FIG. 3, the sprayer 30 has a moving section 302, a hose connection joint 304, pipe sections 306a and 306b, and a plurality of nozzles 308. The moving part 302 has guide rollers (one example of wheels) 310, and can move along the guide member 20 (see arrow A shown in FIG. 1).

[0018] A hose 40 for supplying a chemical is connected to the hose connection joint 304. The hose connection joint 304 is a swivel-type tee, and the joint portion to which the hose 40 is connected can rotate about a rotation axis AX extending in the longitudinal direction of the tube portions 306a and 306b. The joint portion to which the hose 40 is connected is preferably a one-touch joint.

[0019] The pipe sections 306a and 306b are each a pipe extending from the hose connection joint 304 in a direction intersecting the direction in which the guide member 20 extends. The tube portions 306 a and 306 b are supported by the moving portion 302 .

[0020] The nozzles 308 can spray the chemicals supplied through the hose 40, the hose connection joint 304, and the pipes 306a, 306b toward the ground. Each nozzle 308 is provided on the pipes 306a, 306b at a predetermined angle so that the chemicals can be sprayed evenly on the ground inside the agricultural greenhouse 12. The orientation of each nozzle 308 is adjustable. The overall shape of the spreader 30 is not limited.

[0021] The hose 40 can supply the chemical to the sprayer 30. The hose 40 has a base end connected to the pump 60 (see FIG. 1) and a tip end connected to a hose connection joint 304.

[0022] The electric hose winder (an example of a winding section) 50 is installed outside the agricultural house 12, and has a reel 502, a motor (not shown), and a controller (not shown). The reel 502 is capable of winding up the hose 40 . The motor is a driving source for rotating the reel 502 .

[0023] The controller (not shown) is a controller that drives and controls the motor, and is provided on the side of the reel 502 from which the hose 40 is pulled out. The controller can control the rotation speed of the motor. The rotation speed of the motor is set using a speed adjustment dial provided on the front panel of the controller.

[0024] The rotation of the reel 502 (the rotation of the motor) can also be controlled by a remote controller (not shown). The remote controller is wirelessly connected to the controller and can transmit command signals to control the forward, reverse and stop of the motor.

[0025] The pump 60 is installed outside the agricultural house 12 and can discharge the chemical into the hose 40. The discharge amount of the chemical is adjustable. The pump 60 is, for example, a power sprayer (the power section excluding the sprayer section).

[0026] The chemical liquid tank 70 is a tank for storing liquid chemicals, and is installed outside the agricultural greenhouse 12. The chemical liquid tank 70 is connected to the pump 60 via a tube (not shown).

[0027] It is preferable that the electric hose winder 50, the pump 60 and the chemical tank 70 are placed on, for example, the bed of a vehicle.

[0028] Next, a method for spraying a chemical using the chemical spraying device 10 will be described with reference to Fig. 4. The chemical is sprayed in accordance with the following steps S1 to S4. However, if possible, some steps may be performed in parallel. When carrying out this method of spraying a pesticide, a guide member 20 is installed inside the agricultural greenhouse 12 beforehand.

[0029] (Step S1) A vehicle carrying the sprayer 30, the hose 40, the electric hose winder 50, the pump 60 and the chemical solution tank 70 is parked next to the entrance of the agricultural house 12. Thereafter, the hose 40 is pulled out from the reel 502 of the electric hose winder 50 into the inside of the agricultural house 12.

[0030] (Step S2) The pulled out hose 40 is connected to the hose connection joint 304 of the sprayer 30 .

[0031] (Step S3) The moving portion 302 (see FIG. 3) of the sprayer 30 is inserted into the end of the guide member 20 on the side remote from the electric hose reel 50, and the sprayer 30 is attached. Thereafter, the worker leaves the agricultural greenhouse 12 and closes the door 126 at the entrance 125 of the agricultural greenhouse 12 to the extent that it does not hinder the electric hose reel 50 from reeling in the hose 40 so as to prevent the chemicals from scattering outside.

[0032] (Step S4) When an operator operates the pump 60, the operation of the pump 60 is started, the chemical is discharged into the hose 40 and the sprayer 30 sprays the chemical, and at the same time, the motor (not shown) of the electric hose winder 50 rotates and the reel 502 winds up the hose 40.

[0033] As a result, the hose connection fitting 304 is pulled by the hose 40 and rotated by an angle θ as shown in Figure 1, and then the sprayer 30 moves while being guided by the guide member 20, and the pesticide is sprayed along the longitudinal direction of the agricultural greenhouse 12. When spraying of the drug begins, the operator operates the speed adjustment dial of the controller (not shown) to adjust the winding speed of the reel 502. In other words, by adjusting the winding speed of the reel 502, an appropriate spraying speed (amount of spraying) of the drug is adjusted.

[0034] When the sprayer 30 reaches the end of the guide member 20, the operator stops the rotation of the reel 502 and the operation of the pump 60, thereby terminating the spraying of the agent. Thereafter, the hose 40 is removed from the hose connection joint 304 , and the spreader 30 is also removed from the guide member 20 .

[0035] Second Embodiment Next, a chemical spraying device according to a second embodiment of the present invention will be described. The same components as those in the chemical spraying device 10 according to the first embodiment will be given the same reference numerals and detailed description will be omitted. The chemical spraying device according to this embodiment differs significantly from chemical spraying device 10 in that it does not include guide member 20 and in the configuration of the sprayer. Therefore, the following description will focus on the dispenser.

[0036] The sprayer differs from the sprayer 30 according to the first embodiment mainly in the moving part, which can move on the ground. The moving part has a pair of rollers that roll on the ground. The pair of rollers are columnar or cylindrical, spaced apart in the direction of movement of the spreader, and can rotate around a rotation axis that extends in a direction substantially perpendicular to the direction of movement. The diameter of each roller is, for example, 250 to 400 mm. However, the mobile unit may have any configuration as long as it is capable of traveling through the farmland where the pesticide is to be sprayed.

[0037] The hose connection joint is provided in place of the hose connection joint 304 according to the first embodiment, and is fixed to the front side in the moving direction of the vehicle body supported by the pair of rollers so as to protrude forward. The hose connection joint is fixed at a predetermined height position. This predetermined height position is a height position lower than the pipe parts 306a and 306b, and is in the range of, for example, 80 to 250 mm from the ground. Moreover, it is preferable that the joint portion of the hose connection joint to which the hose 40 is connected can rotate about a rotation axis. This rotation axis extends substantially in a horizontal direction perpendicular to the direction of movement.

[0038] The pipes 306a and 306b are attached at a predetermined height to a support pillar extending upward from the vehicle body, and a relay hose extending from a hose connection joint is connected to the pipes 306a and 306b. The nozzles 308 are arranged at a height ranging from 800 mm above the ground, for example.

[0039] In the pesticide spraying device configured in this manner, the pump 60 begins to operate, discharging pesticide into the hose 40, while the motor (not shown) of the electric hose reel 50 rotates and the reel 502 winds up the hose 40, allowing the sprayer to spray the pesticide while moving over the ground.

[0040] As described above, according to the drug spraying device 10 of the first embodiment and the drug spraying device of the second embodiment, the drug is sprayed while moving by being pulled by the hose 40, so that the drug can be sprayed with less effort compared to cases where the device is not configured in this manner.

[0041] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and all changes in conditions that do not depart from the gist of the present invention are within the scope of application of the present invention. The location where the pesticide spraying device 10 according to the first embodiment and the pesticide spraying device according to the second embodiment are used is not limited to the inside of the agricultural greenhouse 12.
