Marine blow-throwing bait feeder for pound

Abstract

A marine blow-throwing bait feeder for a pound comprises a direct current controlling and setting box and a battery jar, wherein the direct current controlling and setting box, the battery jar and a direct current motor are electrically connected with one another; a bait casting disc consists of a direct current motor, a shell, a throw-blowing impeller, a material falling port and a material outlet; the throw-blowing impeller consists of a soleplate, an impeller base and a plurality of profiled vanes, wherein the profiled vanes are uniformly distributed on the soleplate; the external end of each profiled vane is provided with a slot; and the whole throw-blowing impeller meets the dynamic balance requirement. The battery jar is used as the power supply of the bait feeder so that the bait feeder can be directly arranged on a boat and carry out uniform bait-throwing operation in any distance on the water surface together with the boat, thus leading the bait feeding in the pound to be more reasonable and scientific. As the external end of the impeller is additionally provided with the slot, when the granulated feeds are fallen into the material casting disc, both complete granulated feeds and fine granulations can be cast or blown into the pound under the high-speed rotation of the impeller; more importantly, the bait feeder thoroughly avoids the serous accidents generated due to guy creepage of alternating current.

Description

Technical field: [0001] The invention relates to a feeding machine for aquaculture. Background technique: [0002] In the process of aquaculture, feed must be regularly fed every day. The current feeder is composed of a box cover, a hopper, a feed adjustment plate, a vibrating feed trough, a throwing tray, a frame and an electric control box. The granular feed to be fed is put in the hopper, and the output volume is controlled by the feeding regulating plate. The vibrating feeding trough sends the granular feed into the throwing pan, and then the granular feed is thrown into the fish pond by the throwing pan. To achieve mechanized throwing, this type of erbium throwing machine is usually installed on the bank of the fish pond. The driving motor on the throwing plate and the driving motor of the vibrating feeding trough are powered by 220V mains power, and the fixed-point throwing is carried out on the fish pond bank. Erbium throwing machine has many disadvantages in actual ...

Problems solved by technology

[0003] ①Due to the limited throwing distance of the erbium feeding machine, and the fixed-point throwing bait is close to the pond bank, many fish live in deep water, and they will not come to shallow water to eat. Feeds cannot be eaten, causing local waters to deteriorate at the feeding point and polluting water quality

The more scientific bait feeding method is mobile feeding, that is, artificial punting, moving and artificial throwing. This method is only suitable for small-area fish pond operations, and is not suitable for large-area waters. It must be equipped with an electric bait feeding machine. However, the existing bait feeding machine The machines are all alternating current, people can only lead a long wire from the pond bank to the boat, and perform fixed-point casting in waters of different depths. Although this is slightly better than the original fixed-point casting, it still fails to achieve the expected bait casting. As a result, at the same time, it is very unsafe to pull a long wire from the pond bank to the boat through the wire, and once the electricity leaks, it will cause serious consequences for the death of fish and people.

[0004] ②Existing bait throwing machines are only suitable for throwing granular feed, and it is not possible to throw small particles, which are usually scattered in the bait throwing machine. Every time the bait throwing machine is thrown, the bait throwing machine must be maintained once to remove the fine granular feed. Otherwise, the bait throwing machine is easy to be blocked, and at the same time, the throwing of the feed is not thorough, and the utilization rate is not high. However, even in the pellet feed, there are fine particles to varying degrees due to reasons such as filling, handling, extrusion, friction, etc.
