Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tobacco stalk pulling machines, and provides a self-propelled tobacco stalk pulling machine suitable for hilly areas, capable of improving the degree of automation of stalk pulling, reducing the labor intensity of manual cleaning operation, and shortening the maintenance time in the later period. BACKGROUND

[0002] In the process of tobacco planting, a large number of bacteria exist in the tobacco stalks left in the field after the tobacco leaves are picked, which can directly infect the tobacco leaves planted the next year, and even cause absolute loss in severe cases. In addition, the roots of the tobacco stalks are developed, and manual removal is time-consuming and labor-intensive. Therefore, in order to ensure the stability of the tobacco area and the tobacco farmers and enable the sustainable development of tobacco production, the remaining tobacco stalks, tobacco bags and roots must be cleaned as much as possible. A variety of tobacco stalk pulling machines have been successfully developed in China, such as the tobacco leaf and straw pulling device disclosed in Chinese patent 2014203273275, which reduces the labor intensity of the tobacco farmers to a certain extent, but the labor intensity of the later bundling and transportation operation is still very high, and the operation efficiency is low. The full-automatic tobacco straw pulling, soil shaking, bundling and carrying device disclosed in Chinese patent 2022213521327 realizes the integrated operation of pulling, soil shaking and bundling, but during use, the relatively short tobacco stalks pulled are prone to falling to the ground in front of the conveying chain and the straw pulling channel, and manual cleaning is still required, so the degree of automation is low. Other tobacco stalk pulling machines on the market have complex power transmission mechanisms, long maintenance time in the later period, and once a component is damaged, the machine needs to be stopped for overall maintenance, which delays the stalk pulling process. The operation intensity of the large-scale planting of tobacco fields is high, and it is difficult to adapt to the planting row distance of each tobacco stalk, and large machinery is not suitable for hilly areas.
