PROBLEM TO BE SOLVED: To solve problems in lever type that next feed is not allowed to fall without returning to original position, the lever is moved several tens of thousand times and is therefore worn to cause breakdown, so that generation of bridge cannot be automatically overcome, and a feeder by the present applicant (registration NO. 2021457) has an excellent manner, but there is a case where an exhaust port is immersed in water and discharge of feed may be difficult.SOLUTION: In the present invention, a receiving plate hole is opened and closed due to eating action of a livestock, impact generated upon opening and closing cuts out bridged feed so that it falls to a feed tank, and a feed bar automatically returns to a front original position due to gravity distribution of a feed container. The volume of falling feed is restricted by increment/decrement of a receiving plate hole area by restriction of forward or back movement of the feed bar. Even in a case where an opening of the receiving plate hole is kept, falling of feed is not continued and weak vibration makes repeated intermittent falling and stopping. A feed exhaust port is never wet with water, and thus feed discharge is never made difficult. Such smooth feeding provides positive effect on growth of the livestock. Since there is no site to be worn, and thus a never-broken livestock feeder may be provided.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】レバ-式では元の位置に戻らないと次の飼料の落下が出来ない。レバ-は数万回可動さすため摩耗し故障の原因になりブリッジの発生を自動解消出来ないなどの欠点があった。特許出願人による(登録第2021457号)給餌器は優れた方式だが吐出口が水に浸り飼料排出が困難を生じる場面がある。【解決手段】本発明は家畜の食餌行動で受け板穴を開閉しその開閉時に生じる衝撃でブリッジ化した飼料を切り崩し餌槽に落下してエサ棒は飼料容器の重力配分で手前元位置へ自動復元する。飼料の落下量はエサ棒の前後移動を規制して受け板穴面積の増減で行うが、受け板穴の開口が持続した場合でも、飼料の落下が連続することはなく微振動で落下と停止が間欠的に繰り返えされる。飼料吐出口が水に濡れないため飼料排出を困難にする事も無い。このスム-ズな給餌は家畜の成長に好影響を与え摩耗する箇所もないので故障がない家畜用給餌器を提供出来る。【選択図】図1
