The guide pipe 112 includes a vertical portion 112A and an inclined portion 112B, and can smoothly guide the bait 1 in the hopper 110 to a transport pipe 120 described later.

  In the vicinity of the hopper 110, a vertical transportation pipe 120 is provided. The outlet of the guide pipe 112 is connected to the side surface of the transport pipe 120. The transport pipe 120 conveys the pellet-shaped bait 1 toward the drop port 104 directly below, and a blade-type conveyor 130 extending in the vertical direction is disposed inside. The blade-type conveyor 130 has guide blades 132 extending spirally around a vertically extending rotary shaft 131, and the guide blades 132 are rotated to ensure that the bait 1 is directed toward the drop port 104 directly below. It is designed to be transported.

  A movable impeller 140 is disposed immediately below the drop opening 104. The movable impeller 140 scatters the bait 1 falling from the drop opening 104 to the center of the rotating plate 141 by rotation, and radiates around the rotating plate 141 as shown in FIGS. 3 and 5. Plural (three in the illustrated example) dropping notches 141A extending in the direction are provided. A bait receiving portion 141B is formed at the center of the rotating plate 141, and a plurality of (three in the illustrated example) guide plates 142 for guiding the bait 1 that has fallen to the bait receiving portion 141B further toward the dropping notches 141A. It is provided so as to surround the bait receiving portion 141B.

  The rotating plate 141 is provided with adjusting blades 143 that can adjust the scattering direction and the amount of the bait 1 that has fallen on the bait receiving portion 141B, corresponding to the positions of the notches 141A. Each adjustment blade 143 has an inverted L-shaped cross section as shown in FIG. 4 and is attached to the periphery of the rotating plate 141 via a shaft pin 143A, as shown in FIGS. 5 (A) and 5 (B). Moreover, the scattering direction (scattering angle) of the bait 1 and the amount of scattering can be adjusted by changing the attachment angle with respect to the rotating plate 141. Moreover, the size of the bait 1 which passes each notch part 141A can be adjusted by adjusting the clearance gap between each notch part 141A.

  Each adjustment blade 143 can be held at a plurality of mounting angles (an angle of a horizontal posture and an angle of a tilted posture of a front-falling position) by a stopper 144. The stopper 144 is configured so that the locking ball 144B at the tip can be locked in a plurality of locking holes 143A (for horizontal posture and for tilting posture) provided on the side surface of the adjustment blade 143 by a built-in elastic spring 144A. .

  The rotating plate 141 is horizontally fixed to the tip of the rotating shaft 145. As shown in FIG. 2, the rotating shaft 145 passes up and down the rotating shaft 131 of the vane conveyor 130 and is directly connected to the output shaft 151 of the drive motor 150 disposed above the transport pipe 120. The output shaft 151 of the drive motor 150 is connected to the rotating shaft 131 of the blade type conveyor 130 via the speed reduction mechanism 160, and the movable impeller 140 is rotated by the drive motor 150, and at the same time via the speed reduction mechanism 160. The blade type conveyor 130 is rotated at a speed lower than the rotational speed of the movable impeller 140.

  As shown in FIG. 2, the speed reduction mechanism 160 includes a first gear 161 fixed to the output shaft 151 of the drive motor 150, a small-diameter second gear 162 that meshes with the first gear 161, and a planet that meshes with the second gear 162. A gear mechanism 163 and a third gear 164 meshing with the planetary gear mechanism 163 and fixed to the rotating shaft 131 of the blade type conveyor 130 are configured. The planetary gear mechanism 163 includes a sun gear 163A, a planetary gear 163B, and an annular gear 163B, and a third gear 164 meshes with the annular gear 163B. Then, the planetary gear mechanism 163 greatly reduces the rotational speed from the drive motor 150 and slowly rotates the vane conveyor 130.

  A vibration device 170 that applies vibration is attached to each side surface of the guide pipe 112 and the transport pipe 120. By applying vibration to the guide pipe 112 and the transport pipe 120 by each vibration device 170, it is possible to promote the fall of the bait 1 in the guide pipe 112, promote the conveyance of the bait 1 in the transport pipe 120, and prevent staying.

  As shown in FIG. 1, a storage space 105 with a door 104 is provided on the side surface of the casing 101, and a control device 180 is stored in the storage space 105. The control device 180 controls the drive motor 150 and the vibration device 170, and various settings such as a plurality of feeding program modes including continuous operation and intermittent operation, operation days (day of operation) and operation time, bait transportation speed, and the like. Is possible. In the feeding program mode, feeding conditions can be set in advance.

  A small battery 181 serving as a power source for the drive motor 150 is installed in the casing 101, and a solar power generation facility 182 for charging the small battery 181 is installed on the top surface of the upper lid 103. The casing 101, the upper lid 103, and the hopper 120 are made of a light and rust-resistant material such as FRP, and the guide pipe 112 and the transport pipe 120 are made of a similar material such as vinyl chloride.

  Next, a method of performing a feeding operation using the feeding apparatus 100 having the above configuration as an example for a fish farm will be described.

  First, in the fish farm, the feeding device 100 is installed at a place where a salmon or the like (not shown) can be installed, the upper lid 103 is opened, and a predetermined amount of food 1 is put into the hopper 110. In addition, the angle of each adjustment blade 143 of the movable impeller 140 is adjusted in advance. If each adjustment blade | wing 143 is made into a substantially horizontal attitude | position, the scattering amount of the food 1 will increase and the scattering range of the food 1 will be expanded. If each adjustment blade 143 is inclined downward, the amount of food 1 scattered can be reduced, and the range of food 1 scattered can be narrowed. Finally, the door 104 is opened and a feeding program is set on the control device 180. Alternatively, a preset feeding program is selected.

  When the above preparation is completed, the drive motor 150 is driven according to the set or selected feeding program. The rotation of the drive motor 150 is transmitted from the output shaft 151 to the first gear 161 and the second gear 162 and is decelerated by the planetary gear mechanism 163. Finally, the blade type conveyor 130 is rotated at a low speed via the third gear 164. At the same time, the rotation of the drive motor 150 is transmitted from the output shaft 151 to the rotation shaft 145 to rotate the movable impeller 140.

  The bait 1 thrown into the hopper 110 falls in the guide pipe 112 and travels toward the transport pipe 120, but in the transport pipe 120 in the vertical direction due to the transport action of the guide vanes 132 that rotate at low speed in the transport pipe 120. And is dropped from the outlet of the transport pipe 120 to the bait receiving portion 141B on the upper surface of the rotating plate 141 of the movable impeller 140 immediately below. The bait 1 that has fallen on the bait receiving portion 141B receives the centrifugal force action of the rotating rotating plate 141, scatters to the surroundings through each notch portion 141A, and falls onto the water surface W.

  At this time, when a large amount of the bait 1 is to be scattered over a wide range, each adjustment blade 143 is attached at an angle of a substantially horizontal posture. Also, when it is desired to scatter a small amount of bait 1 in a narrow range, each adjustment blade 143 is attached at an angle of a forward and downward inclined posture, the direction of bait 1 that passes through each notch 141A and scatters is regulated downward, and Adjust the volume to a small amount. In this way, by adjusting the mounting angle of each adjustment blade 143 with respect to the rotating plate 141, the scattering range and the scattering amount of the bait 1 can be adjusted according to the actual feeding situation. Furthermore, a clearance gap can be adjusted according to the magnitude | size of the pellet of the bait 1 to feed.

  According to the feeding apparatus 100 of this embodiment, since the bait 1 is transported by the spiral guide blades 132 provided in the vertical transport pipe 120, the transport of the bait 1 can be performed more reliably than in the conventional apparatus. No food remains or becomes clogged in 120. Therefore, feeding and maintenance work can be easily performed.

  In addition, since the vane conveyor 130 in the transport pipe 120 and the movable impeller 140 directly below the drop port 104 are rotated by one drive motor 150 without being driven by separate motors, the apparatus is reduced in size and simplified. It is possible to reduce production costs and maintenance costs.

  Further, since the variable impeller 140 is provided with the adjustment blade 143 that can adjust the mounting angle with respect to the rotating plate 141, the amount and range of the bait 1 can be adjusted, and therefore the size of the fish farm, the type, number, and growth of the fish farm Appropriate feeding according to the actual situation such as the degree can be performed.

  In this embodiment, one guide pipe that continues from the bottom of the hopper is connected to the transport pipe. However, two guide pipes are connected to the transport pipe, or one guide pipe is branched from the middle. You may make it connect to two places up and down. In either case, when a large amount of food is desired to be fed, a large amount of food can be fed into the transport pipe.

  FIG. 6 shows another embodiment of the feeding device of the present invention, in which an output shaft 151 of a drive motor 150 is connected to a rotating shaft 131 of a blade type conveyor 130 via a speed reduction mechanism 190. The point that the output shaft 151 is directly connected to the rotating shaft 145 for the movable impeller 140 is the same as in FIG.

  The reduction mechanism 190 includes a first gear 191 fixed to the output shaft 151 of the drive motor 150, a large-diameter second gear 192 that meshes with the first gear 191, and a gear that is coaxially integrated with the second gear 192. A large-diameter third gear 193 that meshes with 192A, a large-diameter fourth gear 194 that meshes with a gear 193A coaxially integrated with the third gear 193, and a coaxially integrated with the fourth gear 194 The fifth gear 195 meshes with the gear 194A and is fixed to the rotating shaft 131 of the blade type conveyor 130. Then, the speed reduction mechanism 190 greatly reduces the rotational speed from the drive motor 150, and the blade type conveyor 130 is slowly rotated.

  Thus, according to the feeding device of the present invention, it is possible to realize a feeding device that has a simple structure and thus easy feeding and maintenance without remaining or clogging in the transport pipe.

  The feeding device of the present invention can be used as a device for feeding pelleted food to cultured fish or the like.
