Abstract

PURPOSE:To provide a feeder capable of efficiently releasing a granular fish- culture feed such as feed pellet at a long distance without breaking the form of the pellet. CONSTITUTION:A boot 11 and a feed transfer pipe 2 connected to the boot 11 are placed under a spontaneous flow-down feed storage hopper 1. A centerless auger 22 driven by a variable speed motor 21 and having controllable feed- discharging rate is placed in the feed transfer pipe 2. Compressed air generated by a pressurizing blower 31 is blown nearly at the terminal of the centerless auger 22 in a direction keeping an acute angle to the feed-transfer direction of the feed transfer pipe 2 by using the feed transfer pipe 2 as a pneumatic pipe and the feed is released together with the pressurized air from the tip opening of the feed transfer pipe 2. The releasing effect can be improved by attaching a straightening vane at the joint part of the feed transfer pipe 2 and the air pipe 3 or attaching an orifice at the tip opening of the feed transfer pipe 2.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a fish farm (including shrimp farm).
The present invention relates to a feeding device in a field, and in particular, to a bait machine with the purpose of throwing a granularly processed feed such as pellets into a relatively long distance.

[0002]

2. Description of the Related Art A fish-feeding machine is a method of dropping directly below the feeding machine or very close to it, by dropping or dropping the feed on rotary blades, without specifying the location of aquaculture such as sea surface and lake surface. A method of feeding using the centrifugal force of the rotary blades has been tried.

[0003]

In the above-mentioned fish feeder for feeding fish, when the feed is fed by a method of dropping the feed directly below or very close to the feeder, the feed is placed at the installation position of the feeder. It is possible to feed only a limited distance from the water, and it becomes a limited feeding area in the periphery of the aquaculture surface.To feed the central part of the aquaculture surface, the structure for feeding on the sea surface or the lake surface. Need to be provided. In addition, when equipped with a feeding mechanism that uses rotating blades, granule processing such as pellets is crushed due to the impact on the feed caused by the rotation of the rotating blades, and when it falls on the surface of the culture water, It is scattered and becomes unsuitable for fish's palatability and is not eaten, which is a cause of lowering feed efficiency.

[0004]

According to the present invention, in order to solve the above-mentioned problems, as a means for throwing the feed to a distance, a pressurized airflow is used, so that the feeding to a long distance is possible. At the same time, it is possible to have the effect of preventing crushing of granular feed. In addition, as a function of the feeding device, a centerless auger built in the feed carrier pipe for adjusting and adjusting the feeding amount is driven by a variable speed motor, and the feed speed is controlled by the rotation speed control of the variable speed motor. The central portion cavity of the centerless auger is configured to serve as the passage for the air flow while adjusting the cutout amount.

In addition, in the present invention, in order to efficiently blow the air flow into the feed carrier pipe, a rectifying plate is provided at the connecting portion between the air feed pipe and the feed carrier pipe, and the feed carrier pipe is provided. An orifice is provided at the tip to improve the discharge effect and improve the feeding effect.

[0006]

[Examples] The bait machine according to the present invention will be described with reference to the embodiments shown in the drawings, but the present invention is not limited to the illustrated embodiments, and the present invention is not limited to the claims. It goes without saying that all modifications and alternatives included in the spirit of the invention are also included.

[0007] The lower portion of the feed storage hopper 1 having a volume corresponding to the feeding amount of one or more times receives the flow of the feed (not shown) stored in the feed storage hopper 1, and the feed flow is stagnant. Without doing so, the boot 11 to be introduced into the centerless auger 22 is fixedly installed. A centerless auger 22 is arranged on the inner bottom of the boot 11. The centerless auger 22 has a variable speed motor 21 at one end.
The feed shaft is fixed to the output shaft and the other end is inserted into the feed transport pipe 2 communicating with the boot 11. Therefore, the rotation is accompanied by the rotation of the variable speed motor 21 to feed the feed to the feed transport pipe 2. Transfer.

A pressure blower 31 (for example, a ring blower or the like) is installed outside the funnel portion of the feed storage hopper 1. Installing the pressure blower 31 at this position is effective in preventing the occurrence of the bridging phenomenon of the feed in the feed storage hopper 1. Pressured air 33 generated by the pressure blower 31
Is introduced into the air feed pipe 3 that joins the feed transport pipe 2 via the connecting pipe 32, and is blown into the feed transport pipe 2.

In the feed carrier tube 2, a structure is required for the pressurized air supply 33 to effectively act on the feeding effect. In the present invention, the joining angle between the air carrier tube 3 and the feed carrier tube 2 and The setting of the end position of the centerless auger 22 in the feed transport pipe 2 is the main point of the invention. That is, the air feed pipe 3 is opened at the air feed opening 34 above the feed transport pipe 2 while maintaining an acute angle with the feed transport pipe 2 so as to sequentially feed the feed in the feed transport pipe 2. I am letting you.

Further, in order for the feed transport pipe 2 to exhibit the function of the guide pipe for feeding, the end position of the centerless auger 22 is located at the joint between the air feed pipe 3 and the feed transport pipe 2 as described above. It is set slightly on the discharge tip side of the feed carrier tube 2. As a result, the feed transferred by the rotation of the centerless auger 22 is not subjected to the transfer action at the end of the centerless auger 22, but the pressurized air supply 33 blown out from the air supply pipe 3 causes the centerless auger 22 to move. After being blown into the central part of the feed transport pipe 2, when the smooth inner surface of the feed transport pipe 2 serves as an air guide passage to form a discharge flow, the discharge transport flow is carried to move inside the feed transport pipe 2 toward the tip discharge portion. , Is discharged to the outside through the opening 23 at the tip of the feed carrier tube 2.

Although the installation angle of the feed carrier tube 2 has a great influence on maximizing the feeding effect, the inventors have tried using various angles, combinations of feed types, shapes and the like. As a result, it has been found that an elevation angle of 15 ° is optimal, but this setting is only one example, and various installation angles can be changed.

The end position of the centerless auger 22 is as described above. Further, in the present invention, in order to realize smooth discharge of the feed near the tip opening 23 of the feed transport pipe 2, the center is provided. The lead pitch of the less auger 22 is changed depending on the part of the centerless auger 22. That is, the end side fixed to the variable speed motor 21 is
The boot 11 is in a state of being buried in the feed in the feed storage hopper 1, and the lead pitch of the centerless auger 22 in this portion is the feed transport pipe 2
It is set to be smaller than the lead pitch of the centerless auger 22 located inside. As a result, the feed transport pipe (transfer amount) per rotation of the centerless auger 22 is smaller in the boot 11 than in the feed transport pipe 2, and the feed filling rate in the feed transport pipe 2 is low. The void ratio increases and the passage efficiency of the pressurized air supply 33 is increased,
The feeding function is promoted.

As described above, the present invention is intended to feed the feed by the pressurized air supply 33. As means for further promoting this function, the feed carrier pipe 2 and the air feed pipe 3 are provided. It is possible to install the current plate 4 shown in FIG. 2 at the connecting portion. The rectifying plate 4 is provided at the joint portion between the feed transport pipe 2 and the air supply pipe 3 for feeding the pressurized feed air 33.
The reverse blow inside, that is, the pressurized air supply 33 passes through the center portion of the centerless auger 22 and is provided to play a role of guiding and straightening so as not to blow into the boot 11 side. By installing the flow straightening plate 4, pressurized air supply 33
Does not flow toward the boot 11 and the feeding effect in the feed transport pipe 2 does not decrease.

When the bait machine according to the present invention is used, in order to further amplify the bait function of the machine, the orifice 5 as shown in FIG. Can be attached. As is understood from the above description, it is possible to increase the feed discharge distance by adjusting the air flow of the pressurized air supply 33 in the feed transport pipe 2 and accelerating and discharging the air. By providing the orifice 5 having an appropriate throttling angle at the tip opening 23, it is possible to increase the feeding distance and obtain a wide feeding area.

The reason why the fish-feeding machine is required is that the food is evenly distributed and the feeding work is labor-saving. From the above description, it is understood that effective feeding work can be realized by carrying out the present invention. However, the present invention also realizes labor saving of feeding work by automation of driving. . It is known that in the aquaculture industry, if the conditions such as feeding time, feeding amount, feeding frequency, etc. are not met according to the target fish species, feed efficiency will decrease and pollution of the aquaculture area will be promoted. In order to solve this problem, according to the present invention, a control panel that enables setting of feeding time, feeding amount, feeding time during one feeding operation and feeding rest time, etc. is installed, and various feeding operations are performed. Enabled to correspond to the system.

When a wide feeding area is required using the illustrated embodiment of the present invention, the feeding machine according to the present invention is mounted on the turntable 7 as shown in FIG.
By controlling the rotation angle arbitrarily, it was possible to obtain the desired feeding range.

[0017]

[Effects of the Invention] Regarding the bait machine essential to the recent aquaculture and fishery, if the bait machine according to the present invention is implemented, the feeding work can be automated and labor-saving can be realized, and uniform bait, granular structure such as pellets can be realized. It is important to contribute to increasing the profits of the aquaculture fishery by not only destroying the fish but also efficiently feeding the feed to improve the feed efficiency, and at the same time, preventing the pollution of the aquaculture water area caused by the precipitation of the crushed feed and the excessive feeding.
