Description

A minute cutting apparatus of rice straw for a livestock feed and a method of cutting rice straw minutely}

The present invention relates to an apparatus and method for cutting rice straw, and more specifically, rice straw is automatically put in the cutting, crushing and discharge process is carried out automatically at the same time, automatic rice straw for livestock feed that can adjust the grain size of the rice straw to be cut and crushed It relates to a cutting device and automatic rice straw cutting method using the same.

Domestic cattle, Han beef, beef cattle and cows have more than 6.5 million heads as of April 2012, up 1.2 million heads from about 5.3 million heads in 2008. However, the technology and the environment are very poor compared to the developed countries of livestock, and in particular, the domestic technology for producing the domestic feedstock is insufficient, and the self-organizing feed (TMR) manufacturing farms are small, and the spread of related agricultural technologies is very low.

Currently, domestic livestock farms account for over 40% of livestock production. However, supply and price are unstable because most of feedstock including feed grains depend on imports. Moreover, feed prices are increasing recently in the conclusion of the Korea-US FTA and international competition. It is true that it is getting weaker.

Domestic livestock industry technology development is being conducted mainly by the Rural Development Administration and the National Livestock Science Institute. Technology development for the utilization of rice straw forage has been mainly developed by fermentation and cutting technology. However, the total quality of rice and total barley in the form of large round bales with water content increased fermentation efficiency and improved feed quality, but it was rather uncomfortable to cut rice straw by manpower in individual livestock farms. Feeding the TMR has become more difficult.

As a technology and apparatus for processing large round bales of rice straw in Korea, there is a circular rice straw cutting machine developed by Yeongju Agricultural Technology Center in 2008. The circular rice straw cutting machine has a structure that goes through the discharge step of discharging the straw is cut through the first cutting step of cutting in the large blade and the second cutting grinding step passing through the two cylinders formed projections. However, the first and second stages operate in separate units and use a large fixed power source, so the equipment is very large, and the production efficiency is low due to the manual operation, which is a problem for general livestock farms.

In addition, a technology and apparatus for processing rice straw in the form of a large round bale have been proposed through the patent registration No. 0834707, "Pretreatment processing system of a circular bale forage for TMR compounding and a circular bale pretreatment processing method using the same". However, this facility is also a total system for making feed, and the cut section requires additional equipment to release the large round straw bale and connect it to the cut section, which is so large that it cannot be used in a general livestock farm. In addition, the straw cutting method of the cut section is also made by cutting only while pressing the blade and rice straw, it is difficult to expect a low-grained rice straw.

Most of the domestic facilities mentioned above are mostly large-scale facilities, and because they have a cutting function and a process of manufacturing mixed feed in the second and third grinding processes, there is no dedicated manufacturing machine for processing processing in general livestock farms. .

On the other hand, there are various types of rice straw cutting machines used abroad, but most of them are large equipments, which do not have a scale suitable for domestic livestock farms, and have large power sources, which are restricted in terms of use, and large circular barrels in which rice straw is injected and cut. There is a disadvantage in that the productivity is low because the cutting part is processed to a structure that can only process 1/2 of the bottom surface by rotation. A representative forage processing machine is the “Roto Grind” product of “Burrows Enterprises, Inc.” headquartered in Colorado, USA. It is also a product that is cut and crushed through a large round cylinder, which has low productivity, weighs more than 1.8 tons, and is high. Large machine with a length of more than 2.6m is not suitable for use in domestic livestock farms.

Therefore, in order to use a large round bale as a forage, cutting, grinding and discharging processes are simultaneously performed only by the input of rice straw, and the granularity of the rice straw that is shredded and crushed must be controlled. There should also be a means for producing food that is readily available. Unlike the existing cutting technology, the new forage production technology combines the function of feeding, fine cutting, crushing and discharging rice straw to improve the properties of rice straw, and it is easy to mix with rich feed and additives to reduce the cost of breeding and produce high quality meat. It should be a means to increase the competitiveness of domestic livestock farmers.
