Description

Technical Field

[0001] This utility model relates to the field of tobacco loading equipment technology, specifically to a special electric-driven self-propelled trolley for tobacco loading equipment. Background Technology

[0002] In Yunnan, tobacco is not only a pillar industry but also one of the largest high-quality tobacco leaf production bases in the country. For many years, from field planting to deep processing, it has continuously opened up channels for increasing local fiscal revenue and creating employment opportunities for farmers. The key to turning fresh tobacco leaves into marketable tobacco lies in the curing process; today, heat pump intensive curing barns are gradually replacing traditional earthen curing barns and becoming the mainstream.

[0003] Faced with the massive scale of newly built tobacco curing barns, the tobacco loading process still relies on manual labor, resulting in time-consuming, labor-intensive, and inefficient operations. Existing equipment on the market is polarized: either too expensive for farmers, or small and simple but lacking automation and offering a poor user experience, failing to truly solve the problem. Therefore, developing a self-propelled tobacco loading trolley that is "moderately sized, affordable, highly efficient, and user-friendly" is urgently needed, allowing tobacco farmers to escape heavy manual labor and completely freeing them from arduous handling. To this end, we propose a dedicated electrically driven self-propelled tobacco loading trolley to address these issues. Utility Model Content

The lower movable support 37 is fixedly connected to the slider of the linear guide rail 36, which is fixedly installed on the top of the base frame 1.

[0020] The lifting mechanism 3 is driven by a worm gear reducer 31 during the lifting process. It adopts bearing point contact motion and is guided by a linear guide rail 36, which has low frictional resistance and ensures smooth lifting.

[0021] Specifically, the scissor lift structure 4 includes scissor lift arm 41, scissor lift arm 42, upper support base 43, lower support base 44, upper movable support base 45, and linear guide rail 46. Multiple scissor lift arms 41 are provided and arranged in parallel with each other, and multiple scissor lift arms 42 are provided and arranged in parallel with each other.
