Background technique

As a large agricultural country in my country, it is an inevitable development process for field operations to become mechanized, which can save labor and improve economic benefits. Corn is a common crop in the north. In the past, due to cognitive, policy and economic reasons, farmers basically burned the stalks directly after harvesting. This not only caused a waste of resources, but also polluted the environment. With the development of science and technology, ecological agriculture is the development direction of modern agriculture. As a precious resource, straw has also begun to be reused, and straw crushing and bundling will be one of the main ways. This will not only make use of resources, but also improve The environment in which we live.

However, due to the loose straw and low density, it is difficult to collect and transport, and it is difficult to realize the storage of raw materials for commercial transformation and industrial utilization. Therefore, storing and transporting straw into high-density bales is the key to reducing the cost of raw material collection and storage and promoting the large-scale utilization of straw biomass resources.

At present, the square bale baler can bundle various crop straws such as forage grass and wheat straw, but it cannot harvest standing corn, cotton and other high-stalk crop straws; while the straw crushing and collecting machine can only harvest corn, cotton The stalks of crops with high stalks are crushed and recycled, but they cannot be bundled and formed. Make the use of square bale baler have very big limitation.

At present, there are also straw crushing and collecting machines on the market, but this kind of straw crushing and collecting machine can only crush the straws of high-stalk crops such as corn and cotton, and then recycle the straws with a trailer, but cannot realize straw bundling operations, and the process is single , low operating efficiency and poor economic benefits.
