Description

I. TECHNICAL FIELD

[0001] The present application relates to the field of agricultural and animal husbandry feed processing technology, and particularly relates to a synthetic pasture kneading and stirring machine. II. BACKGROUND

[0002] In 2015, the theoretical resource amount of straw in China was 1.04 billion tons, the collectable resource amount was about 900 million tons, and the utilization amount was about 720 million tons, and the comprehensive utilization rate was about 80%. The utilization approaches mainly include five ways of fertilizerization, feedstuff, base material, energy, and raw material. However, the comprehensive utilization technology of the "five materialization" is very low, the comprehensive utilization level of straw is low, the industrial chain is short, and the industrial layout is unreasonable, and the problems are far from being completely solved. The total amount of straw used for feed in China is nearly 300 million tons per year, and the processing technology of straw has been using the traditional forms of direct feeding by crushing (kneading), yellow storage, and feeding after micro storage. Since the protein content of straw is low (less than 2% on average), the nutrition is insufficient, and livestock is difficult to obtain sufficient nutrient components from the structural feed, which seriously restricts the sustainable development of animal husbandry. The scientific research work in the field of deep processing technology of straw, especially how to realize the substitution of high-quality pasture, is almost blank. The research on the deep processing technology and equipment of straw is to alleviate the shortage of forage resources in China and provide the most basic material basis for the sustainable and healthy development of animal husbandry.

[0003] The development level of animal husbandry reflects the economic development level and the degree of technological progress of a country. In some developed countries in the world, the animal husbandry output value accounts for a high proportion in the total agricultural output value, such as 60% in the United States, 65% in Canada, 74% in Germany, and 57% in France. More than 60% of the animal husbandry output value is converted from forage, so forage production is the most basic and important industry in animal husbandry production. The experience of developed countries in grassland animal husbandry is that when the artificial grassland accounts for 10% of the natural grassland, the total productivity of the grassland can be doubled. Expanding artificial grassland is the main means for these countries to solve the source of roughage, and the scientific research work in the field of deep processing technology of straw, such as the substitution of high-quality pasture, is proposed according to the national conditions of China. III. SUMMARY

[0004] The purpose of the present application is to combine the processing and production technology of synthetic pasture, and to develop an equipment for kneading, flattening, spraying, powdering, and secondary flattening of crop straw, and then stirring and drying.

V. DETAILED DESCRIPTION

[0010] The synthetic forage rubbing mixer is composed of a frame 4, an oblique blade flattening roller 1, a conveying belt 6, a flat flattening roller 5, an electrostatic spraying device 2, a powder spraying device 3, a drum type spiral stirring conveying device 8 and a drying hot air conveying pipe 7. The conveying belt 6 is arranged at the bottom of the frame 4, the oblique blade flattening roller 1 is arranged at the feeding end of the frame 4, the flat flattening roller 5 is arranged at the discharging end of the frame 4, the electrostatic spraying device 2 and the powder spraying device 3 are arranged at the top of the frame 4, the electrostatic spraying device 2 is arranged close to the side of the oblique blade flattening roller 1, the drum type spiral stirring conveying device 8 is connected to the discharging end of the frame 4, and the drying hot air conveying pipe 7 is arranged at the top of the drum type spiral stirring conveying device 8. The oblique blade flattening roller 1 is provided with oblique cutting blades arranged in an interlaced manner on the upper and lower roller surfaces. The conveying belt 6 is divided into two working sections, the upper part of the first section is provided with the electrostatic spraying device, and the upper part of the second section is provided with the powder spraying device. The drum of the drum type spiral stirring conveying device 8 is long, the outer cylinder does not rotate, and the inner spiral stirring conveying shaft rotates.

[0011] In operation, the pretreated crop straw is fed into the oblique blade flattening roller 1, and the oblique blade flattening roller 1 forms longitudinal incisions on the straw in the flattening and rubbing process, and exposes more pulp, which is beneficial to the combination and plastic forming of water, dry powder and straw into forage, and the straw is processed into forage. After the straw passes through the oblique blade flattening roller 1, it is conveyed to the conveying belt 6, and the conveying belt 6 has an electrostatic spraying device 2 above the first section. The electrostatic spraying enhances the rapid and uniform adsorption of mist droplets on the surface of the straw. Then the conveying belt 6 carries the straw into the second section, and the conveying belt 6 has a powder scattering device 3 above the second section. The powder scattering device 3 scatters feed protein powder and other natural additives onto the sprayed straw. After passing through the second section of the conveying belt 6, the straw is sent to the flat flattening roller 5. The flat flattening roller 5 further rubs the water, dry powder and straw. Finally, the straw is fed into the drum-type spiral stirring and conveying device 8. Since the drum-type spiral stirring and conveying device 8 has a long drum, the straw is fully stirred in the drum under the action of the inner spiral stirring and conveying shaft. At the same time, the dry hot air conveying pipe 7 blows dry hot air onto the straw being stirred, so that the feed protein powder and other natural additives are more uniformly combined with the straw, and high-temperature disinfection is performed. Finally, the processed straw is sent to the production equipment of the next process in the synthetic forage processing production process.
