Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in figure 2, the main components of the feed of the invention comprise corn flour, grass meal, wheat bran, rice bran, soybean meal and mixture. Wherein the mixture is prepared by mixing salt, calcium-phosphorus feed and feed containing potassium, iron, zinc and other trace elements. Because the nutrition requirements of the live pigs at different growth stages are different, the feed proportion is different, and the following steps are included:

the main components of the feed for the suckling piglets (10 kg-30 kg) are 40% of corn flour, 5% of wheat bran, 16% of rice bran, 24% of soybean meal and 5% of a mixture. The piglet in the lactation period grows and develops rapidly, the metabolism is vigorous, but the development of a digestive organ is still incomplete, the digestive function is poor, and the piglet can gradually adapt to the feed by being matched with the feed which has high nutritional value, easy digestion and absorption and good palatability according to the characteristics when being matched with the feed.

The main components of the feed for nursery pigs (30 kg-60 kg) are 55% of corn flour, 10% of grass meal, 10% of wheat bran, 16% of rice bran, 24% of soybean meal and 5% of mixture. The nursery pigs need protein to increase the weight of the piglets, and the carbohydrates provide energy, minerals, trace elements and vitamins for their activities to enhance the metabolic capacity of the body.

The main components of the feed for the fattening pigs (60 kg-90 kg) are 38 percent of corn flour, 30 percent of grass meal, 10 percent of rice bran, 17 percent of bean pulp and 5 percent of mixture. Fattening pigs are a link determining economic benefits in pig raising production, and the breeding cost in the period accounts for more than half of the total cost. The period is the stage of the fastest growth speed of the live pigs, the utilization efficiency of the feed is high, and the required nutrient substances are more.

The main components of the feed for the slaughtered pigs (90 kg and above) comprise 30% of corn flour, 37% of grass meal, 18% of rice bran, 10% of soybean meal and 5% of a mixture. In this stage, the pig is fed with the feed to be controlled to feed freely, increase the activity and build up the body, mainly the green grass feed is taken as the main feed to control the economic cost.

The material conveying structure 10 mainly comprises a pressure valve 101, a material pipe 102, a material port 103, a circular truncated cone pipe 104, a travel switch 105 and a fixed pipe 106. The pressure valve 101 is located at the top of the material pipe 102, a material port 103 is formed in the material pipe 102, the circular truncated cone pipe 104 is communicated with the material pipe 102, and the travel switch 105 is located on the circular truncated cone pipe 104.

The upper pipe 201 is fixedly communicated with the fixed pipe 106, and the connecting pipe 202 is communicated with the upper pipe 201. The fixing ring 203 is fixed at the flange connection position of the connecting pipe 202 and the upper end pipe 201, and plays a certain sealing role. The lower tube 204 is fixedly connected to the connecting tube 202, and the first fixing plate 205 is fixedly connected to the connecting tube 202 via a connecting block 206. The first fixing plate 205 is connected to the mounting frame 12 by bolts, and supports the fermentation structure 20. Three arc-shaped heating plates 207 are arranged inside the connecting pipe 202, and a liquid injection port 208 is connected to the lower end pipe 204.

The quantitative structure 30 mainly comprises a second fixing plate 301, a cylinder 302, an air valve 303, an arc-shaped frame 304, a baffle 305, a rack 306 and a gear 307.

The baffle 305 is rotatably connected to the arc frame 304, and the baffle 305 is engaged with the lower port of the circular truncated cone tube 104. In the initial state, the baffle 305 seals the lower port of the circular truncated cone 104. The rack 306 is fixed on the output shaft of the cylinder 302, and the gear 307 is fixedly connected with the baffle 305. Wherein, the rack 306 and the gear 307 are always in a meshed state.

When the travel switch 105 controls the cylinder 302 to contract, feed enters the circular truncated cone pipe 104 from the material opening 103, and the rack 306 drives the baffle 305 to rotate through the gear 307. After the baffle 305 is separated from the circular truncated cone 104, the feed enters the fermentation structure 20, and the leaven is added from the liquid injection port 208. The arc heating plate 207 heats the feed, and the temperature is controlled to be about 45 ℃. The palatability of the feed is improved through microbial fermentation, and the nutrient substances in the feed can be improved after fermentation, so that the secondary digestion of the live pigs is promoted. The feeding cost can be reduced, the energy feed fermented by the leaven is converted into the mycoprotein feed, and the use amount of the protein feed can be reduced by about 50 percent, so that the total feeding cost is greatly reduced.

In the prior art, fermented feed must be uniformly stirred, if the feed cannot be uniformly stirred, nutrition cannot be guaranteed to be supplied in a balanced manner, so that on one hand, pigs suffer from malnutrition and deficiency, and on the other hand, the pigs are poisoned. Even if the feed formula is scientific again, the feeding environment is excellent again, and the good feeding effect cannot be obtained. As shown in fig. 7 to 9, the connection assembly 4 includes a mixing frame 41, and a connection plate 42 is fixedly connected above the mixing frame 41. The connecting plate 42 is provided with a plurality of flange pipes, the number of the flange pipes corresponds to that of the feeding assemblies 2, and the flange pipes are connected with the feeding assemblies 2. Wherein, the mixing frame 41 is fixedly connected with an inclined plate 43 inside, and the inclined plate 43 inclines from the middle part to two sides. This construction ensures that the feed will naturally slide down.

The number of the stirring assemblies 5 corresponds to the number of the feeding assemblies 2, each stirring assembly 5 comprises two support legs 51, and a stirring cylinder 52 is fixedly connected between the two support legs 51. Wherein, a motor 53 is connected on the supporting leg 51 at one side, an impeller 54 is fixedly connected on the output shaft of the motor 53, and the impeller 54 is rotatably connected inside the stirring cylinder 52.

The impeller 54 stirs and mixes the feed uniformly, and the motor 53 is turned off after the feed is stired and mixed uniformly. And the stirring time of each batch of feed is 15-20 minutes, and too much or too little time is not beneficial to uniform stirring. In addition, the stirring time is also an important factor in the uniformity of mixing. The time is too short, the uniformity can not be ensured, and the time is too long, so that the feed can generate the layering phenomenon due to over mixing, and the aim can not be achieved.

As shown in fig. 10, the opening and closing member 6 is located at the lower end of the agitating drum 52. The opening and closing assembly 6 comprises a fixed valve 61, a butterfly valve 62, a rotating shaft 63, a connecting disc 64, a fluted disc 65, a handle 66, a handle 67 and a return spring 68.
