In recent years, a batch of bundling machines for crops such as grains, pastures and the like are developed aiming at the bundling and recycling problem of cotton stalks, and the bundling machines mainly adopt a small square bundle recycling mode and a large round bundle recycling mode, wherein the small square bundle recycling mode needs to crush cotton stalks first and then compact the cotton stalks, and the large round bundle is used for recycling whole cotton stalks after directly shearing the cotton stalks, so that the bundling machine has greater advantages in energy consumption, bundling density and failure rate. The existing large round bale cotton stalk recovery method generally adopts disc type or reciprocating type cutting and directly feeds into a baling chamber to form integration of pickup, compression, forming and bale unloading operation, the formed large round bale has high density, is convenient for long-term storage and long-distance transportation, and can provide stable raw material supply for large-scale utilization of cotton stalk energy (biomass power generation), feed (ammoniation treatment) and the like, thereby effectively reducing comprehensive cost. However, the problem that the machine is required to stop winding and unloading the bales after the baling bin is full still exists, so that the labor is doubled, and the operation efficiency is reduced. Therefore, there is a need to provide an improved large round bale cotton stalk bundling and conveying device and a non-stop operation method to overcome the problem that the current large round bale recycling operation needs to stop bundling, and improve the operation efficiency.
