## 1 Introduction  
One of the world's major cash crops for energy and sugar is sugarcane [1]. One of the world's leading producers of sugarcane is in China [2], while the majority of China's sugarcane-growing regions are located in Guangxi, Yunnan, Guangdong, and other provinces. The degree of mechanization of sugarcane harvesting in China is less than 5% [3], due to the country's diverse terrain and lack of standardized standards for sugarcane cultivation. Sugarcane leaf stripping is an essential aspect of sugarcane harvesting, affecting the economic advantages of harvesting and sugar production for sugarcane farmers [4], and it is critical to create leaf stripping technology that is appropriate for China's planting circumstances. Currently, sugarcane leaf stripping equipment primarily serves as a supporting part of the sugarcane combine harvester, which can perform both harvesting and leaf stripping simultaneously. However, the combine harvester's leaf stripping [5,6] has a high impurity rate, is prone to clogging, and has an unstable operating performance. Therefore, Guangxi University proposed a step-by-step method for harvesting sugarcane that involves harvesting, transferring, and centralizing the leaf stripping of crops independently. This method can be used on small terrain, like hills and mountains, and has the advantages of being highly flexible, having a low rate of impurity during the leaf stripping process, and matching the sugar mill process in comparison to the cut-off type [7] and the whole culm type combine harvester. Pull-type sugarcane defoliation equipment, developed by Guangxi University [8], was utilized as the main component of the step-by-step sugarcane harvesting mode. This equipment has numerous benefits over the conventional centrifugal defoliation [9; 10] method, including a low rate of impurities, a low rate of damage, and a long service life of the defoliation elements. Nevertheless, pull-type sugarcane defoliation equipment still has limitations, including the requirement for even and systematic sugarcane spreading during feeding and the potential for clogging when the feeding volume is excessively high. The entire mechanical process has not yet been accomplished, and it is currently often utilized to physically aid in the sorting and feeding of sugarcane. Therefore, it is essential to design a conveying system that is compatible with the equipment used for step-by-step sugarcane defoliation. Conveying systems are essential to the entire process of mechanically harvesting sugarcane. Scholars both domestically and internationally have conducted extensive studies on this topic in an effort to guarantee the integrity of sugarcane harvesting conveyor systems and lessen the obstruction of the sugarcane conveying process. [PERSON] [11] observed through experimental research that keeping an appropriate speed during conveying will improve both the cutting quality of sugarcane and the stability of conveying. The authors in the literature [12; 13] developed a small-scale sugarcane defoliator, which is manually fed into the sugarcane to finish the defoliation process, with a leaf removal rate of over 80%; nevertheless, the defoliator's operational efficiency is only 2 to 3.5 t/h. Since the conveying system logistics volume is too large, [PERSON] et al. [14], employed the use of range sensors to scan through the cross-sectional area of an object, and calculate the total volume and mass of the logistics over some time, so that the volume of material flow can be reasonably controlled., And, through a test, they verified that it is feasible. The literature [15; 16] describes the addition of internal cane splitters and auxiliary cane rollers to the conveying channel to restrict the direction of stray canes and lessen clogs brought on by cane stacking and accumulation.
