Abstract:  In order to ensure the stability of the transport quality of straw after baling, it is necessary to wrap the surface of straw after compression. The netting mechanism of straw square baling machine is designed and researched, and a netting mechanism of straw square baling machine is developed, which can realize the automatic netting of straw during the baling process, including conveying mechanism, compression mechanism and netting mechanism. The working principle and working process of the mechanism are emphatically described, and the 3D software is used to model and make a prototype for field test. The results of comprehensive analysis show that the machine has stable operation, good performance and stable structure, and each bundling index meets the requirements of use. The baling rate, regular baling rate, antifall rate and bale density of the baling machine were tested before and after the opening of the net binding function. The test results of the opening of the net binding function showed that the bale rate was 994%, the regular bale rate was 98%, the antifall rate was 96%, and the bale density was 170 kg/m3, which can produce better quality bales and facilitate secondary transportation.
