Description

Technical Field

[0001] The invention belongs to the field of agricultural machinery. Background Art

[0002] A straw baler is a machine used for straw recycling. After picking up the straw from the ground, it is crushed, kneaded, and soiled, and then transported to the collection bin through a fan, and then falls from the collection bin into the compression bin, and the straw is packed into bales through a hydraulic device. The straw bundles need to be covered with a layer of packaging bags during transportation. The existing straw balers mainly solve the automation of baling, which is achieved through the control of an electronically controlled hydraulic valve. However, manual methods are still used in the baling and bagging process. An operating room is specially set up at the outlet of the straw baler, and workers stand in the operating room to manually bag and complete the baling process. This method has a low degree of automation and high work intensity, and is not suitable for long-term continuous work, so it is inefficient. In addition, the straw baler will raise a lot of dust into the operating room during operation, and the working environment is poor. Therefore, realizing baling automation and achieving true full automation is an urgent problem that straw balers need to solve. Summary of the invention
