Description

A kind of cotton straw drawing device

technical field

The utility model relates to the technical field of agricultural tools, in particular to a cotton straw pulling device.

Background technique

Cotton stalk is a by-product of cotton planting industry. It refers to the cotton stalk without branches, leaves and bolls. It has a high degree of lignification, rich bast fiber, high bulk density and calorific value. Cotton stalk is crushed and compressed. It is a good Biomass briquettes. After the cotton is harvested, the cotton stalks need to be pulled out, and then the land is plowed to facilitate planting in the coming year.

Cotton stalks are deeply rooted, and with the absorption of soil nutrients and water by the cotton root system, there is agglomeration on the land surface, which further increases the difficulty of pulling out cotton stalks. It will cause part of the root system to remain in the soil, which will affect the leveling of the land. Therefore, people often use the method of hand-pulling to clean the straw, but the long-term pulling action not only causes damage to the palm, but also requires frequent bending, which is harmful to the body. cause harm, therefore, we propose a cotton straw pulling device.
