Description

Automatic liquid feeder{AUTOMATED LIGUID PHASE FEEDING APPARATUS}

The present invention relates to an automatic liquid feeder, and more particularly, to a liquid automatic feeder capable of automatically mixing and supplying dry feed and liquid raw materials.

In general, in pig farms that raise pigs, automatic feeders are installed that automatically supply feed within the pig house. The configuration of such an automatic feeder for pig farming is known as Korean Patent No. 10-1201545, Patent No. 10-1277590, and the like. Specifically, the automatic feeder for pig farming includes an upper supply pipe disposed in a horizontal direction at the top to transfer feed, a feed storage box for receiving feed from the upper supply pipe and temporarily storing the feed, and a feed placed below the feed stored in the feed storage box. It includes a feed supply to supply to the substrate. Here, the feed supply unit uses a screw or a rotating sphere connected to a shaft rotated by a motor, and a predetermined amount of feed is supplied to the lower feeder plate according to the rotation of the screw or rotating sphere.

These conventional automatic feeders are mainly for supplying dry feed (dry feed) such as compound feed. Blended feed is a feed made by properly processing and blending two or more kinds of feed ingredients and various types of cattle for breeding purposes, and is mainly composed of powders or granules. However, since the production cost per 1 kg of feed is remarkably high, the selling price of these blended feeds is very high, which increases the difficulty of pig farms.

Liquid feeding is an alternative to these blended feeds. Liquid feeding is a repetitive automatic feed optimized for pig growth by stirring water and feed or liquid by-products and grains and liquid raw materials for a certain period of time in a large stirring tank. This is how to feed. When liquid feeding to weaned piglets, the surface cross-sectional area of long villi and microvilli that absorb nutrients is much higher than that of dry feeding (feeding only blended feed), and the feed intake and growth rate are significantly higher (Pig International 5, 2013). ,June issue release). This liquid feeding system consists of a stirring tank, agitator, pump for transfer, various valves for pipelines, and intake tanks. A large amount of liquid feed is prepared and stored in the agitating tank, and then pumped by the transfer pump to 300 meters to 500 meters. It is supplied into the pig house through pipelines inside and outside the meter. At this time, it is operated based on a centralized computer system because various controls such as raw material supply, mixing, feeding amount control, feeding time, feeding location, and washing method are required.

As described above, the conventional automatic liquid feeding system is a method of producing liquid feed in a centralized manner in a large agitated tank and then transferring and feeding it to each zone, and has a disadvantage in that it is difficult to install and maintain because the overall scale of the system increases. In addition, when the length and slope of the transfer pipeline or the transfer height (height of the pig house) is large, there is a problem that it is difficult to transfer due to the limitation of pump capacity, and it is difficult to apply it to pig houses with a height of 3 stories above the ground. In addition, since a certain portion of water and compounded feed are injected into the mixing tank at the same time, the ratio of feed and water is not uniform, so the quality of the liquid feed is not constant, and the residual feed that remains inside the transfer pipeline after the liquid feed is supplied. In the process of re-supplying the washing water to the pipe for treatment, sanitary problems such as bacterial growth and wastewater treatment problems occur when remixing with the structure of remixing with washing water exposed to residual feed in the process of reducing the washing water again. If the mixed feed particle is large or floats on the water during agitation, water and feed are moved separately and the transfer pipe is blocked, the feed transfer capacity per hour is limited, and the PVC pipe for liquid transfer It has many disadvantages, such as that it is difficult to transfer quickly due to its small size, and that it requires a lot of space in the kitchen room because it requires a mixing tank and a washing water tank.

It can solve all the problems of the feeding system. In particular, since dry feed, not liquid, is transferred to each feeding area, there is no limitation of pump capacity or supply problem at high ground clearance, which is a problem when transferring liquid feed, and there is no hassle of washing the pipe after transferring the liquid feed. The advantage is that there is no hygiene problem such as bacterial growth. In addition, since the ratio of dry feed and water is always constantly added, high-quality liquid feed can be uniformly prepared at all times. In addition, since it is a method of individually manufacturing and supplying a small amount of liquid feed in individual feeding zones, rather than a method of mass-producing and transferring liquid feed in a centralized manner, it has the advantage of simple equipment, less space requirements, and easy management.
