Technical Field

The invention relates to the technical field of straw treatment, in particular to a dividing device with an annular cutting structure for crop straw treatment.

Background

Straw, known as ligusticum in ancient times, also known as straw grass, refers to the stem and leaf parts of the stems and leaves of the mature and threshed gramineous crops such as rice, wheat and corn, wherein the straw of rice is often called as rice straw and ligusticum oryzae, and the straw of wheat is called as wheat straw. Before industrialization, farmers use the straws in the eight-door way, and the straw is very abundant. For example, in southern China, people dry and store rice straws, and the rice straws can be used as household articles such as firewood, woven seat cushions, mattresses, brooms and the like, used for bedding livestock rings, used for feeding livestock, and used for composting and returning the fertilizer to the field, even used for manufacturing roofs of simple houses and the like, and are rarely wasted directly. In China for over two decades, due to popularization of coal, electricity and natural gas and abundance of various industrial products, the demand of rural areas on straws is reduced, the treatment of a large amount of straws becomes a serious social problem, and although laws are forbidden, many local farmers still directly burn the straws in the fields, so that the consequences of air pollution, fire disasters, incapability of normally lifting and descending airplanes and the like are caused. The environmental protection agency points out that when the straws are immediately buried on the spot during harvesting, the method has no air pollution and is a better fertilizing method.

To this end, the chinese application patent No.: CN201610220954.2 discloses a straw cutting device and cutting method, the on-line screen storage device comprises a base, first infrared correlation switch, the holding tank, travel switch, a spring, the knife rest, the guide pillar, the cutter, the infrared correlation switch of second, a frame, a cam, first sprocket, the driving chain, the second sprocket, be provided with the holding tank that holds the straw on the base, holding tank notch department both sides are provided with a pair of first infrared correlation switch, holding tank notch left side is provided with travel switch, the cutter sets up directly over the holding tank, cutter fixed mounting is on the knife rest, the knife rest can slide from top to bottom along two guide pillars, be provided with on two guide pillars and conveniently be provided with the spring, frame fixed connection is on the knife rest, the cam sets up in the space that frame and knife rest enclose, the cam is connected with first sprocket, first sprocket passes through the driving chain and is connected with the second sprocket, the second sprocket. The long axis of the cam and the short axis are on the same straight line, and a pair of second infrared correlation switches are arranged at the end point of the short axis of the cam and the knife rest.
