Description

Rice-straw spreader {Rice-straw spreader}

The present invention relates to a rice straw spreader, and relates to a rice straw spreader capable of sequentially moving and cutting rice straw from loaded bales of rice straw and spraying the cut rice straw while being moved by a tractor.

In general, rice straw has been used as feed for livestock such as cows and goats since ancient times, and has been mainly used as feed for livestock after cutting rice straw into a certain size and mixing it with bean pods. At this time, chopping was widely used to cut rice straw to a certain size, but the use of chopping has disappeared due to threshing using a combine. It was compressed, rolled into a circle, stored, and supplied as feed for livestock during the winter.

These circular rice straws are cut into sizes suitable for livestock to eat, and then selectively mixed with hay according to the nutritional status of livestock. Therefore, it is very difficult for workers to cut it to have a certain size.

Therefore, in recent years, various types of cutters have been provided as a way to efficiently cut circular rice straw, which is a heavy material.

The circular rice straw cutting machine disclosed in Korean Patent Registration No. 10-0749014 includes a frame that is connected to a moving means and moves, and a moving support means having a housing fixedly disposed on the top of the frame and in which a bundle of rice straw to be cut is placed; Rice straw cutting means disposed on the other side of the housing to cut the rice straw bundle; Rice straw guiding means having a rice straw conveying unit and a rice straw fixing unit for fixing the guided rice straw bundles, spaced apart from the lower surface of the housing and guiding the rice straw bundles toward the rice straw cutting unit while entering and exiting the inside of the housing; It is arranged spaced apart on the lower side of the lower surface of the housing and is connected to the rice straw guiding means and the rice straw cutting means, and consists of a driving means for operating the rice straw guiding means and the rice straw cutting means.

However, such a circular rice straw cutting machine has a disadvantage in that continuous operation for a series of processes of receiving, guiding, and cutting rice straw is not easy since the driving means for driving the device is composed of a cam and an operating link. In addition, the conventional circular rice straw cutting machine can cut rice straw to a predetermined length, so there is a problem in processing a large amount of rice straw because the rice straw processing speed is slow.
