Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sugarcane harvesting equipment, in particular to a self-propelled sugarcane field whole-stalk leaf-stripping transporter. Background Art
[0002] Guangxi is the main sugar cane producing area in China, and the sugar cane area accounts for more than 60% of the country. The existing sugar cane harvesting methods are commonly the following two methods: First: manual whole-stalk harvesting, which accounts for about 90%. Advantages: low impurity content in sugarcane, strong flexibility, and not affected by plots and weather. Disadvantages: low efficiency and high harvesting cost. Second: sugarcane combine harvesting, which accounts for about 10%. Advantages: high efficiency and relatively low harvesting cost. Disadvantages: greatly affected by plot size, sugarcane planting pattern, sugarcane lodging conditions, weather, etc., and field harvesting losses are large (about 8% to 10%, mainly due to the loss of incision sugar water and crushing losses caused by poor harvesting of lodging sugarcane) and high impurity content (the impurity rate of sugar mills is generally 8-15%, mainly sugarcane stumps and mud), and the comprehensive loss rate is greater than 15%. Among them, the sugarcane segmentation method has a congenital defect: the sugarcane has many cuts, and the cuts will become moldy, which will affect the production of the sugar factory. Therefore, the sugarcane must be dispatched to the factory for pressing and sugar production within 24 hours after being cut, which increases the dispatch difficulty of the sugar factory; the sugarcane has many cuts and loses water quickly. If it is not dispatched to the factory in time, there will be a significant weight loss, which will affect the income of sugarcane farmers. Due to many unfavorable factors, the sugarcane segmentation method is a sugarcane harvesting mode that neither sugar factories nor sugarcane farmers like, and they have been looking for other efficient and low-loss solutions.
[0003] The comprehensive loss of sugarcane harvesting by combine harvesting machines is often higher than the cost of manual harvesting of sugarcane, which is the fundamental reason why sugarcane combine harvesting machines have been difficult to promote. However, with the aging of the population, the decrease in the number of working-age people in rural areas, and the increase in labor prices, the proportion of manual harvesting of sugarcane has been decreasing year by year, and it is an irreversible trend for machine harvesting to replace manual harvesting.
[0004] In order to solve the problems of large losses and high impurity rate in the current sugarcane combined mechanized harvesting, the Guangxi sugarcane area has proposed a step-by-step sugarcane harvesting model: the three steps of sugarcane cutting, transportation and impurity removal are carried out separately. The main purpose is to separate the sugarcane felling process which is prone to sugarcane losses. Depending on the situation of sugarcane lodging, the sugarcane is cut and spread by a cutter or cut manually. There is almost no loss from felling, and sugarcane stumps and mud are basically eliminated.
[0005] At present, the step-by-step sugarcane harvesting mode is to cut and lay the whole stalks (or manually cut), load them by machine, transport them over a short distance, and centrally cut and remove impurities. Centralized cutting and impurity removal requires a workshop of at least four mu, a power supply of more than 50 KVA, and a proper number of small transfer vehicles to transport the raw sugarcane from the field to the workshop for centralized cutting and impurity removal. The sugarcane leaves piled up in the workshop should be cleaned up in time. During the sugarcane cutting process, the sugarcane stumps are basically eliminated, and the impurity removal effect is better than that of the traditional field-integrated sugarcane combine harvester. However, it has the problem of secondary cleaning of sugarcane leaves, and increases the input of site, machines and labor, resulting in high sugarcane harvesting costs. Summary of the Invention

[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] 1. By using the leaf stripping and transporting machine of the utility model, after the whole cane stalks are cut and laid in front, the raw cane is grabbed and fed by the robotic arm hydraulic claw, the whole cane stalks are stripped of leaves, and the whole cane stalks after leaf stripping and impurity removal are fed into the rear carriage. After the carriage is full, it is transported to a nearby sugarcane transfer station, and then the cane is grabbed by a grab machine and loaded onto a large truck of the sugar factory. The process is simple and efficient. After the sugarcane is cut, there is no need for secondary transfer and leaf stripping; the impurities such as the leaves and tails after sugarcane leaf stripping and impurity removal can be directly discharged into the sugarcane field, without the need for secondary cleaning and stacking of the leaves, and without the need for a fixed operation site and high-power power supply; the whole cane stalks are harvested and stripped of leaves, without problems such as incision mildew and excessive water loss caused by sugarcane segmental impurity removal, which can reduce the input of site, machines and labor, and reduce the sugarcane harvesting cost.
[0019] 2. By using the leaf stripping mechanism of the utility model, the rotation speed of the clamping and conveying roller is less than that of the leaf stripping roller, which can ensure stable differential speed, reliable leaf stripping, and the structure of the clamping and conveying roller can perform the operation of cutting off the tail of the tail; at the rear side of the leaf stripping channel, a centrifugal fan is used to blow away the impurities such as the leaves and tails on the cane stalks, which can improve the impurity removal effect and reduce the impurity content rate of the cane stalks; using the centrifugal fan to blow the leaves instead of the traditional grille interception mode of the leaves, without the contact interception of the grille, the problem of leaf congestion at the outlet can be solved, and there is no need for manual cleaning frequently, ensuring that the leaf stripping mechanism can work continuously and improving the work efficiency.

Each longitudinal leaf stripping plate is inclined from the inside to the outside in the opposite direction of the rotation direction of the leaf stripping roller, and each transverse leaf stripping plate is arranged perpendicular to the axis of the leaf stripping roller, which can further improve the effect of leaf stripping and impurity removal.
[0021] 4. The carriage adopting the present utility model is inclined downward from front to back.

The power device is installed on the vehicle frame 10 to provide power for the traveling mechanism 8, the feeding conveyor belt 2, the robotic arm hydraulic claw 1 and the leaf stripping mechanism 3. By using the leaf stripping transporter of the present utility model, after the whole stalk is cut and laid in the front, the raw material sugarcane is grabbed and fed by the robotic arm hydraulic claw 1, the whole sugarcane stalk is leaf stripped, and the whole sugarcane after leaf stripping and impurity removal flows into the rear carriage 9.
