Abstract

(57) [Summary] [Purpose] To expand the range of feed for automatic feeding machines. [Structure] A spray pipe 9 having a bent tip is rotatably connected to the tip of a feed injection discharge tube 6 of an automatic feeder. The spray tube 9 is rotated by the drive of the motor 14 to spray the feed over a wide range.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention mainly relates to an automatic feeding machine used in a fish farm.

[0002]

[Prior Art]

 Conventional automatic feeders used in fish farms include those disclosed in, for example, Japanese Utility Model Publication No. 50-10390 or Japanese Utility Model Publication No. 2-9653.

As shown in FIG. 4 and FIG. 5, in these products, an artificial feed of powder or granules mainly containing fish meal filled in a feed tank 1 is introduced into a guide cylinder 2 at the lower outlet of the tank 1. A motor 3 is installed to connect the grooved roller (hereinafter, referred to as a roller) 4 that rotates in one direction and an adjustment plate 5 whose lower end faces one side of the outer periphery of the roller 4 to a lower portion of the guide tube 2. It is designed to be discharged into the discharge pipe 6 provided, and the feed is sprayed from the tip of the discharge pipe 6 by the air flow sent to the discharge pipe 6 by the rotation of the blow fan 8 connected to the rear end of the discharge pipe 6. To be done.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned one, as shown in Fig. 4, the discharge pipe is fixed in one direction, and the feed sprinkled toward the fish farm falls almost on the same water surface in the same trajectory. However, there is a problem that the spraying range is limited.

Therefore, an object of the present invention is to expand the spraying range by making the trajectory of the sprayed feed different.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the conventional automatic feeding machine, the tip of the discharge tube is rotatably connected to a sprinkling tube whose tip is bent, and a rotating device for rotating the sprinkling tube is provided. Of.

[0007]

[Action]

 In the automatic feeding machine configured in this way, the direction of the bent tip of the sprinkling pipe changes with the rotation of the sprinkling pipe, the trajectory of the feed to be sprinkled changes, and the spreading range widens.

[0008]

【Example】

 An embodiment of this invention will be described below with reference to FIGS. The same parts as those of the conventional example shown in FIGS. 4 and 5 described above are designated by the same reference numerals and the description thereof will be omitted.

As shown in FIG. 2, the automatic feeding machine shown in FIG. 1 has a rear end of a sprinkling tube 9 whose tip is bent via a bearing 10 rotatably connected to the tip of a discharge tube 6. The distribution pipe 9 is rotated by the rotating device 11. Although various kinds of devices can be considered as the rotating device 11, here, a gear 12 is attached to a rotating shaft 15 of a drive motor 14, and the gear 12 is meshed with a gear 13 attached to the outer circumference of the spray pipe 9. There is.

This embodiment is configured as described above. Now, when the feed tank 1 is filled with the feed and the automatic feeder is operated, the feed moves down the guide tube 2 and the roller 4 The air is discharged from the gap between the adjusting plate 5 and the adjusting plate 5 into the discharge pipe 6, and is carried to the tip of the spray pipe 9 by the air from the blow fan 8 flowing inside. At this time, the spray pipe 9 is rotated by the rotating device 11, and its tip end is in a swinging state as shown in FIG. 3 and is rotating in a circle. For this reason, the feed sprayed from the spray pipe 9 is sprayed in different directions at each spraying position, and spread over a wide range with different trajectories.

[0011]

【effect】

 Since the present invention is configured as described above, it is possible to widely spread the feed.

Claims (1)

[Claims for utility model registration] [Claim 1] In an automatic feeding machine, the feed carried into the discharge pipe from the upper peripheral portion of the discharge pipe is sprayed from the tip of the discharge pipe by a blow fan connected to the rear end of the discharge pipe. An automatic feeding machine characterized in that a sprinkling tube having a bent tip end is rotatably connected to the tip of the discharge tube, and a rotating device for rotating the sprinkling tube is provided.
