Description

Fattening pig feeding device

Technical Field

The invention relates to the technical field of breeding, in particular to a fattening pig feeding device.

Background

About 14 billion fat pigs are sold in China every year, half of the fat pigs are in China, the consumption amount of pork in China is the first in the world, and the fat pigs have a huge pork market. The cost of the feed accounts for about 70% of the total feeding cost in the feeding process of the fat pigs, and how to reduce the feed waste and save the feed digestion on the premise of meeting the growth requirement is a significant thing. The existing fattening pig raising method is mainly characterized in that large-stall feeding is adopted, more than 20 large stalls are arranged in each house, a double-sided stainless steel trough or a cylinder feeder is arranged in front of each two large stalls, pigs on the two stalls share one set of feeding equipment, the trough is always fed, and free feeding of fat pigs is achieved without limitation of feeding. The situation that the pigs occupy the trough strongly or are only arched for playing with the feed can occur in the pig herd with the feeding mode, so that the feed is wasted, and the breeding cost is high. The feeding mode without limit feeding enables pigs to eat freely all the time, so that the rapid weight gain of the pigs is realized, but the results of partial fat of the pigs, reduction of the utilization rate of feed and the like are inevitable, and the requirements of consumers on healthy low-fat diet are more and more not adapted; in large-stall breeding, a single pig cannot be noticed, and the health condition of the single pig is difficult to find at the first time, so that a plurality of sick pigs miss the optimal treatment time; on the other hand, the food safety is more and more concerned by the masses, and the food tracing is also the trend of fattening pig feeding in the future.

The growth condition of fat pig is monitored, weight data is also an important index, the feed conversion ratio of each pig can be calculated through the weight, the conventional weight measurement technology adopts a weighing sensor and is matched with a weighing fence, but the mode is not only low in efficiency and high in cost, but also can cause disturbance to the fat pig, and therefore the pig can not be popularized and popularized in a large area on the feeding of the common fat pig.

The large-stall feeding device designed by foreign equipment manufacturers can record the total feed intake of the whole large-stall swinery, but cannot monitor the feed intake of single-head fattening pigs and cannot realize the feeding of the fattening pigs according to a curve.

Disclosure of Invention

In order to overcome one of the technical defects or technical defects in the prior art, the invention discloses a novel fattening pig feeding device, which adopts the technical scheme that:

a fattening pig feeding device comprises a plurality of large fences, wherein a stockline for conveying feed is arranged at the top of each row of the large fences, and the fattening pig feeding device is different from the prior art in that: n half limit fences are fixedly arranged in each large fence close to a corridor wall to form N-1 feeding positions, N is an odd number larger than 2, a through body feeding groove penetrating through all the half limit fences is fixedly arranged at a position close to the ground, a mounting plate is fixedly arranged above the through body feeding groove and between every two adjacent half limit fences, the height of the mounting plate is as low as possible so as not to interfere with the feeding of the growing and fattening pigs, an RFID card reader is mounted on the mounting plate, visual cameras are suspended at positions, which are located above the central half limit fence and are not more than the maximum body length of the growing and fattening pigs away from the rear part of the through body feeding groove, feed boxes integrated with blanking controllers and the number of which is equal to the number of the feeding positions are suspended in the air, feed pipes of the feed boxes are communicated with the feed lines, and blanking pipes of the feed boxes respectively extend to the positions, corresponding to each feeding position, of the through body feeding grooves.

Compared with the prior art, the complete set of fattening pig feeding device comprises a stockline, a trough, an adjustable half limit fence, weight acquisition equipment, identity recognition equipment, feed intake acquisition equipment, controller data collection and the like, wherein a camera monitors a feed intake area, the weight of a pig in the feed intake area is calculated through an image recognition technology, all information is collected to an upper computer, information such as feed-meat ratio, feed intake duration and the like of each pig is analyzed through software, and data is collected to the upper computer through a wireless networking mode to form a complete set of feeding system, so that the daily feed intake and weight of a single fattening pig can be monitored, the growth condition of the pig is monitored, problems occur, an alarm is given in time, and the feeding system is processed in time; the feeding mode of limited feeding after the later-period feeding of the fattening pigs can be realized by feeding through a set feeding curve, so that the feed consumption and the feeding cost are saved; the whole large-stall pig only shares one set of weighing system, so that the equipment cost is reduced.

Furthermore, the feed boxes which are half the number of the feeding positions and are integrated with blanking controllers are suspended in the air, feed pipes of the feed boxes are communicated with the feed lines, and two blanking pipes of the feed boxes respectively extend to the positions, corresponding to the two adjacent feeding positions, of the through body feeding trough. The two feed intake positions of the feed box are designed to share one feed intake position, so that the feed intake requirement is met, the number of half feed boxes is reduced, and the manufacturing cost is reduced.

Furthermore, each half limiting fence is hinged with a fence door capable of opening and closing. Realize the regulation to the interval, guarantee that the pig is only normally taken and is not influenced by other pigs.

Further, the distance between two adjacent half-limiting fences is slightly larger than the maximum shoulder width of the fattening pig. Only one pig is guaranteed to be in a feeding state, and food robbery is prevented.

Furthermore, the middle of the half-limiting fence is provided with a solid iron plate so as to ensure that the RFID card readers do not interfere with each other.

Further, the blanking of each blanking pipe is controlled by a motor independently. The electronic ear tag on the pig ear is identified by combining the RFID, the identity of the pig is identified, and accurate feeding is performed according to a set feeding curve.

Interpretation of terms:

a half limit fence: the positioning fence with the open rear end has a column interval when pigs eat, so that the pigs can be prevented from being disturbed by other pigs, the rear ends of the pigs freely come in and go out, and the pigs can share one feeding place to eat.

An RFID card reader: the equipment for reading the electronic ear tag information is matched with the electronic ear tag to realize the rapid and accurate identification of the identity of the single pig, and uploads the identification to the controller to record the ingestion duration of the pig.

Visual weight estimation: the body shape images of the pigs are obtained by using the visual cameras, and the weight of the target pigs is estimated by combining a specially designed algorithm program, wherein the accuracy rate is more than 97%.

Automatic blanking equipment: the motor is controlled to operate by the blanking controller, the motor drives the packing auger to drop the feed from the feed box, and the encoder at the tail end of the motor accurately records the number of turns of the motor.
