Sow free choice feeding device

Abstract

The invention discloses a sow free choice feeding device, comprising a hopper, a laying-off amount adjusting mechanism, and a discharging mechanism. The laying-off amount adjusting mechanism is arranged in the hopper. The hopper comprises a C-type housing, a front side plate, a bottom plate, and a stock guide rail. The front side plate is fixed on the front surface of the C-type housing. The bottom plate is welded on the bottom of the C-type housing, and a gap between the bottom plate and the front side plate is reserved as a discharge port. The stock guide rail is welded between the bottom plate and the rear side wall of the C-type housing, and the stock guide rail is aligned at the bottom plate on the discharge port. The discharging mechanism comprises a laying-off plate, a mandril, a top cap, and a spacer pin. The laying-off plate is on the stock guide rail. The top cap is under the bottom plate. The upper end of the mandril passes through the bottom plate and is welded with the stock guide rail and the laying-off plate, and the bottom end is welded with the top cap. The spacer pin is welded on the mandril which is under the bottom plate. The device is simple in structure, laying-off amount can be freely adjusted, and can prevent laying off on eyes and noses of pigs. The device reduces manual laying-off frequency, and sows eat fresh feed and meanwhile the feed would not overflow, so that objectives that feed is not wasted and manual work is saved are achieved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry equipment, in particular to a free feeder for sows. Background technique [0002] There are several types of feeders for sows. At present, most of them are open feeders fixed on the feeding line or delivery bed and ordinary free feeders. The advantage of this type of feeder is its versatility. Strong; but has the following disadvantages: 1. If the feed is put into the trough, it will not be able to eat fresh feed for a long time. 2. If there is too much feed, the pigs will easily move the feed outside and cause feed waste. 3. Feed several times a day. Satisfying the food intake of sows, there are problems such as consuming labor. 4. Common ad libitum feeding equipment cuts materials from the middle, and the feed goes down to the eyes and nose of pigs to affect the eating and respiratory health of sows. Contents of the invention [0003] In order to solve the above technical problems, t...

[0002] There are several types of feeders for sows. At present, most of them are open feeders fixed on the feeding line or delivery bed and ordinary free feeders. The advantage of this type of feeder is its versatility. Strong; but has the following disadvantages: 1. If the feed is put into the trough, it will not be able to eat fresh feed for a long time. 2. If there is too much feed, the pigs will easily move the feed outside and cause feed waste. 3. Feed several times a day. Satisfying the food intake of sows, there are labor-intensive problems. 4. Ordinary ad libitum feeding equipment cuts the material from the middle, and the feed goes down to the eyes and nose of the pigs, which affects the eating and breathing health of the sows.
