摘要： A creep feeder furnishes a blow molded container with an inner chamber, a top port and a bottom port. The top port provides passage for feed into the inner chamber and is closed by a snap fit cap. The bottom part provides a throat, narrowing valve seat and narrower delivery tube. A blow molded, hollow valve is enclosed in the bottom part and operates with the valve seat to dispense feed upon demand of an animal. The valve has a bulbous head with a gradually narrowing under surface that engages with the valve seat to close the bottom port. A narrower valve stem hangs in the delivery tube, and the delivery tube keeps the valve substantially aligned in the bottom port to insure proper sealing between the head and valve seat. The device dispenses feed upon an animal pushing up the bottom end of the stem and spacing the head from the seat. Feed in the chamber then flows down through the bottom port. An umbrella hanging in the chamber reduces the weight of the feed resting on the valve head to reduce the force needed to push up the valve for dispensing feed.
摘要翻译：蠕动式进料器配有带有内腔，顶部端口和底部端口的吹塑容器。顶部端口提供用于进入内室的通道，并且通过卡扣盖封闭。底部提供喉部，狭窄的阀座和较窄的输送管。吹塑成型的中空阀被封闭在底部，并且与阀座一起操作以根据动物的需要分配饲料。该阀具有球形头部，其下表面逐渐变窄，与阀座接合以关闭底部端口。较窄的阀杆悬挂在输送管中，并且输送管保持阀基本上对准在底部端口中，以确保头部和阀座之间的适当密封。该装置将动物向上推动杆的底端并将头部与座椅隔开。进料室然后通过底部端口向下流动。悬挂在室中的伞减小了保持在阀头上的进料的重量，以减少推动用于分配进料的阀所需的力。

摘要： An animal feeding device, especially for pigs, has an overhead feed metering or regulation mechanism formed of a cylindrical member resting in a slot across the bottom of a feed hopper to close the slot and prevent feed from falling from the hopper. The bottom of the member is accessible from below the slot and the pig causes feed to fall from the slot by pushing the member up with its nose to open the slot. When the member is released by the pig, it falls back down into the slot to close same. The member can be a tube or pipe retained in operable open and closed position by a rod extending therethrough.
摘要翻译：特别是猪的动物饲养装置具有顶部进料计量或调节机构，其由圆柱形构件形成，圆柱形构件放置在穿过进料斗底部的槽中，以封闭狭槽并防止进料从料斗中落下。构件的底部可以从槽的下方进入，并且猪通过将构件向上推动从而使饲料从槽中落下以打开槽。当成员被猪释放时，它落回到槽中以使其相同。该构件可以是通过延伸穿过其中的杆保持在可操作的打开和关闭位置的管或管。
