Device capable of chopping cotton stalks and returning chopped cotton stalks into field and application method thereof

Abstract

The invention relates to a device capable of chopping cotton stalks and returning chopped cotton stalks into a field and an application method thereof, belonging to the technical field of agriculturalmachinery. According to the invention, the device is controlled through a cab; during harvesting of the cotton stalks, a stalk support unit gathers the cotton stalks to draw close to a cutting unit through rotation; the cotton stalks are cut off through the cutting unit and fall down toward the interior of the device under the action of the stalk support unit; the cut cotton stalks are deliveredto a crushing unit through a conveyor belt and crushed through a crushing unit; the crushed cotton stalks are spread into the field; meanwhile, cotton stalk stubbles remained in soil are dug out through a digging plowshare arranged below the device during advancement of the device. The device provided by the invention adopts electric power as an energy source, is simpler, more convenient and quicker to operate, is cleaner and more environment-friendly, has lower cost, small and exquisite structure and strong maneuverability, and is applicable to small and medium cotton fields for chopping of the cotton stalks and returning of the chopped cotton stalks into the field; and compared with large machinery, the device provided by the invention is more convenient and has higher efficiency.

Description

technical field [0001] The invention relates to a device for chopping and returning cotton stalks to the field and an application method thereof, belonging to the technical field of agricultural machinery. Background technique [0002] At present, China's cotton production ranks first in the world, and the average annual cotton production is nearly one-third of the world's total cotton production. Cotton stalks, as a by-product left over from cotton picking, are important straw resources in China, but at present Cotton stalks are mainly used by cotton farmers as biofuels, which not only have low utilization efficiency, but also require a series of processes such as pulling out stalks, collecting, transporting, drying, and storing cotton stalks, and each link requires a lot of labor. Under the background of scarce young and strong labor force, this kind of use is obviously not ideal, and because of this, some places, especially some small cotton fields in the hilly and mounta...

Problems solved by technology

[0012] The technical problem mainly solved by the present invention is that the general-purpose straw chopping and returning machine is bulky and heavy, and is not suitable for small field operation and the cutting method is to interrupt rather than cut, causing the cotton stalks after cutting to be "broken and threaded" and cotton The stalks have not been removed, affecting the subsequent planting of crops, the invention provides a device for chopping and returning cotton stalks and its application method
