Tobacco stalks are remnants of tobacco leaves after harvesting, and according to statistics, more than 200 ten thousand tons of tobacco stalks need to be treated every year in China, and the quality of the treatment of the tobacco stalks directly influences the planting of the next crop and the maintenance of land quality. The tobacco stalks have more plant diseases and insect pests, so the tobacco stalks are not suitable for crushing and returning to the field, the most common treatment method in China is that the whole tobacco stalks are pulled out of the field, but the tobacco stalks are treated in a manual pulling mode in many areas. At present, some stalk pulling equipment is also available, but the function is single or the overall efficiency is lower, and a matched collecting device is often needed to collect the stalks after the stalks are pulled out of the soil.

If the patent name is tobacco stalk cleaning and recycling soil preparation machine, the patent with the document number of CN115735445A, the stalk pulling device of the patent consists of a rotating shaft, a supporting frame and a deflector rod, the technology and the application background of the stalk pulling device are mature, and the stalk pulling device also has better stalk pulling experience in the actual stalk pulling process. The driving device is arranged above the frame, and the power output from the driving device to the rotary tillage device, the stalk pulling device and the conveyor belt is completed by belt conveying connection. Although this patent has certain advantage, this patent does not have self-discharging device behind collecting the tobacco stalk, because the tobacco root of tobacco stalk is very big, so the collecting box just fills very easily, still need to clear up whole tobacco stalk and retrieve the soil preparation machine and stop the manual work and lift off the tobacco stalk in the collecting box and just can go on, so not only extravagant human cost, and efficiency can also become low. In addition, the patent has no limiting device in the conveying process, and the tobacco stalks cannot be ensured to accurately fall into the collecting box.
