The present invention is generally related to a device provisioning feeds to domestic animals, and more particular to a device for spraying feeds to domestic animals fanned in a wide area.
When domestic animals such as fowls are fanned in a wide area, the primary concern is to dispense feeds effectively so as to keep the animals healthy and well-nourished.
Conventionally, feeds are placed in an elongated feeder where the animals can take the feeds by themselves. However, some large animals may occupy the feeder and push smaller animals aside. The smaller animals therefore cannot have enough feeds and become malnourished.
A conventional feed dispensing device is provided to solve the described problem, where feeds are kept in a high place and then sprayed out by centrifugal force to make sure that every animal can have enough food. The conventional feed dispensing device has a hollow container with doors disposed on its circumferential wall. When the container is rotated up to a certain speed, feeds inside the container push open the doors and are thus sprayed around. However, the drawback is that the doors cannot be pushed open when the amount of feeds in the container is not enough.
There is another rotational feed dispensing device where a door-less container is rotated by a driving device to spray the feeds also by centrifugal force. As there is no door, no large amount of feeds are left in the container. But there are still some residual feeds in the container.
As such the present invention provides a feed spraying device where a controller controls a second driving unit to rotate a spraying wheel for a period of time after the feed spraying device is turned on so as to clear residual feeds. The spraying wheel's blades have bended tips to increase the distance at which the feeds are sprayed. After the first driving unit stops rotating the loading wheel, the controller continues to control the second driving unit to rotate a spraying wheel for a period of time before the spraying device completely stops, so as to prevent feeds are left in the feed spraying device. The present invention therefore resolves the residual feed problem of the prior art and enhances the coverage of feed spray. Additionally, the feed spraying device has built-in driving units, and no external driving devices are necessary.
The feed spraying device contains a casing member having and a feed outlet, a top cover having a feed inlet, a number of partitions separating an inner space of the casing member into a first section, a second section, and a third section where the second section is connected to the feed inlet, the first section is connected to the feed outlet; and the first and second sections are connected via an opening on a partition separating the first and second sections. The feed spraying device further contains a loading wheel configured in the second section beneath the feed inlet, at least a brush configured in the second section along an edge of the feed inlet, a spraying wheel configured in the first section, a first driving unit configured in the third section connected to the loading wheel, a second driving unit configured in the third section connected to the spraying wheel, and a controller configured in the third section controlling the first and second driving units. Feeds are supplied into the second section through the feed inlet, sent to the first section via the opening by the loading wheel, and then sprayed out of the feed outlet by the spraying wheel.
A major objective of the present invention is that, after the feed spraying device is turned on and before it stops, the controller engages the second driving unit to drive the spraying wheel to rotate for a period of time so as to clear residual feeds in a feed storage room. In addition, the spraying wheel has blades of bended tips so as to increase the distance that the feeds are sprayed. The device therefore resolves the residual feed problem of the prior art and enhances the coverage of feed spray.
Another objective of the present invention is that the brush is made of a flexible material, and the brush has a length that the brush touches the blades of the loading wheel so as to control the entry of the feeds.
Another objective of the present invention is that a bottom side of a feed loading room is slant towards the feed storage room so as to move the feeds more smoothly.
Another objective of the present invention is that the feed storage room has a downwardly curved bottom side so as to move the feeds more smoothly.
Another objective of the present invention is that the spraying wheel has two parallel sets of blades, each set has a number of blades, each blade is bended for an angle at a tip of the blade, and each blade has a flange along a lateral side. The bended tips increase the distance that the feeds are sprayed.
Another objective of the present invention is that the loading wheel has a first connection element so as to join to the first driving unit, and the first driving unit is a motor.
Another objective of the present invention is that the spraying wheel has a second connection element so as to join to the second driving unit, and the second driving unit is a motor.
Another objective of the present invention is that the second connection element is located in a center of the casing member, an axle of the second driving unit runs through the partitions and the second connection element, and a cap covers an exposed end of the axle of the second driving unit.
Another objective of the present invention is that the feed spraying device further comprises a side cover joined to a side of the casing member by flexible elements so that the side cover is capable of being flipped open to allow access to the casing member's inside.
The feed spraying device's top cover, side cover, and partitions provide convenient manufacturing and installation of the casing member.
