Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to an agitation granulation device for feed in fish farming, which has become increasingly popular in recent years.

<Conventional technology> In fish farming, fish such as sardines are fed as bait, but in order to make it easier for the fish to eat, a method is used in which the bait is first minced into fine pieces and then granulated into a certain size before being cast as bait. ing.

By the way, once fish start eating, they tend to eat continuously for a certain period of time, but if they stop eating for a while, they tend not to continue eating after that. However, conventional agitation granulation equipment has only one agitation tank, so it is not possible to continuously feed the fish, and the feeding must be temporarily suspended even during periods when fish are most likely to eat. However, after that, the fish's appetite decreased, resulting in the double disadvantage of reduced feeding effectiveness and loss of feed. Moreover, there was a problem in that the seawater was contaminated due to the sedimentation of the bait.

<Problems to be Solved by the Invention> The present invention aims to eliminate the above-mentioned drawbacks and provide a stirring granulation device capable of continuous feeding.

<Means for solving the problem> The gist of the present invention is to install two left and right stirring tanks side by side with a partition wall as a boundary, and to pass one rotating shaft through the two stirring tanks. In addition, a stirring blade is attached to the same rotating shaft, and a stirred bait outlet with an opening/closing damper is provided at the bottom of the left and right stirring tanks, respectively, and the bait outlet is located inside the stirring tank, which is juxtaposed at the bottom of the stirring tank. An opening was made in the bait transfer cylinder containing the screw conveyor, and the tip opening of the bait transfer cylinder was made to house the screw conveyor, and further communicated with the bait delivery cylinder having a built-in granulation device at the tip. This is an agitation granulation device for fish feed, which is characterized by the following.

<Example and operation> Below, the agitation granulation device for fish feed according to the present invention is as follows:
The embodiment will be described in detail with reference to the drawings showing the embodiment.

What is shown in the figure is a partially cutaway overall explanatory view of the agitation granulation device according to the present invention, in which left and right agitation tanks 2 and 2' are arranged side by side with a partition wall 1 as a boundary, and the same left and right agitation tanks 2, 2' through which one rotating shaft 3 passes,
Stirring blades 4 and 4' are attached to the rotating shaft 3, respectively, and the rotating shaft 3 can be driven by a hydraulic motor 5. In addition, feed inlets 6, 6' are provided at the top of the left and right stirring tanks 2, 2', and feed and nutrients, etc., are put into the feed inlets 6, 6', and the left and right stirring tanks 2, 2' are fed with feed and nutrients. 2, 2', and the stirred feed is transferred to the same left and right stirring tanks 2, 2'.
The bait is delivered to the bait transfer cylinder 8 through the agitated bait outlets 7, 7' equipped with opening/closing dampers provided at the bottom. In addition,
The agitated bait take-out ports 7, 7' with opening/closing dampers can be opened and closed by rotating tank damper handles 9, 9'. Also, a screw conveyor 10 having spiral blades attached to a rotating shaft is housed inside the bait transfer cylinder 8, and by rotating the screw conveyor 10, the bait is transferred to the tip, and the bait is transferred. The bait is sent out from the tip opening 11 provided at the bottom of the tip of the tube 8 to the bait feeding tube 12 . Furthermore, the fed feed is transferred to a granulating device 14 built in the tip by a feeding screw conveyor 13 contained in the feed feeding cylinder 11.
The transferred feed is granulated and sent out by the granulating device 14.

In addition, the granulation device 14 presses the transferred feed onto a disk having a plurality of circular holes of a required diameter, and the pressurized feed passes through the circular holes and is inserted to the required size. The bait is granulated into appropriate sizes using rotating blades attached radially. The switching lever 15 is a switching lever that allows the rotation of the stirring blades 4, 4' to be rotated in the forward direction or in the reverse direction.

<Effects of the invention> As stated above, according to the invention, bait can be continuously cast using two stirring tanks.
Unlike conventional methods, there is no need to interrupt bait casting for agitation when the fish are actively predating, so the fatal disadvantage of "suppressing the fish's appetite" is eliminated, and furthermore, feed loss is reduced and time is shortened. It is also connected to

In addition, the amount of feed can be adjusted accurately using the two stirring tanks, reducing losses and preventing the occurrence of diseases in fish farming due to seawater contamination caused by sedimentation of feed.
