Description

Technical Field

[0001] The invention 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 impurity removal has a congenital defect: the sugarcane has many cuts, and the moldy cuts 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 difficulty of dispatching 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 impurity removal 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 harvesting mode of sugarcane is whole-pole cutting (or manual felling), machine loading, short-distance transportation, and centralized cutting and weeding. Centralized cutting and weeding requires a workshop of at least four acres, a power supply greater than 50KVA, and a suitable number of small transfer vehicles to transport raw sugarcane from the field to the field for centralized cutting and weeding. The piles of sugarcane leaves in the workshop must be cleaned up in time. The sugarcane felling process basically eliminates sugarcane stumps, and the weeding effect is better than that of traditional field integrated sugarcane combine harvesters, but it creates the problem of secondary cleaning of sugarcane leaves, and increases site investment, machine investment, and labor investment, so the cost of sugarcane harvesting remains high. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. With the leaf stripping and transporting machine of the present invention, after the whole stalks are cut and laid in the front, the hydraulic claws of the mechanical arm grab the raw sugarcane for feeding, the whole stalks of sugarcane are stripped of leaves, and the whole stalks of sugarcane after stripping and impurities are collected into the carriage at the rear. After the carriage is full, it is transported to the nearby sugarcane transfer station, and then the sugarcane is grabbed by the grabber and loaded onto the large truck of the sugar factory. The process is simple and efficient, and there is no need for secondary transportation and leaf stripping of sugarcane after felling; the sugarcane leaves and tails and other debris after leaf stripping and impurities removal can be directly discharged into the sugarcane field, and there is no need to clean the accumulated sugarcane leaves for a second time, and no fixed work site and high-power power supply are required; whole stalk harvesting and leaf stripping do not have the problems of moldy cuts and excessive water loss caused by sugarcane segmentation impurities removal, which can reduce the input of site, machinery and labor, and reduce the cost of sugarcane harvesting.

[0019] 2. With the leaf stripping mechanism of the present invention, the rotation speed of the clamping and conveying roller is lower than that of the leaf stripping roller, which can ensure a stable differential speed, clean and reliable leaf stripping, and the structure of the clamping and conveying roller can perform a tail cutting operation on the tail; a centrifugal fan is used on the rear side of the leaf stripping channel to blow away impurities such as sugarcane leaves and tails on the sugarcane stalks, which can improve the impurity removal effect and reduce the impurity content of the sugarcane stalks; a centrifugal fan is used to sweep the sugarcane leaves instead of the traditional fence-type interception of sugarcane leaves. Without the contact interception of the fence, the problem of sugarcane leaves blocking the outlet can be solved, and there is no need for frequent manual cleaning, which ensures that the leaf stripping mechanism can work continuously and improves work efficiency.

[0020] 3. The leaf stripping plates of the present invention include a plurality of longitudinal leaf stripping plates and a plurality of transverse leaf stripping plates. 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.

[0021] 4. The carriage of the present invention is tilted downward from front to back. Under the dual effects of inertia and gravity, the sugarcane stalks are accumulated to the rear of the carriage, which prevents the sugarcane from being stuck at the front end of the carriage and hindering the leaf stripping mechanism from spraying the sugarcane into the carriage.

The power device is installed on the frame 10 to provide power to the walking mechanism 8, the feeding conveyor belt 2, the mechanical arm hydraulic claw 1 and the leaf stripping mechanism 3. With the leaf stripping and transporting machine of the present invention, after the whole stalks are cut and laid in the front, the hydraulic claw 1 of the mechanical arm grabs the raw sugarcane for feeding, the whole stalks of sugarcane are stripped of leaves, and the whole stalks of sugarcane after stripping and impurities are collected into the carriage 9 at the rear. After the carriage 9 is full, it is transported to a nearby sugarcane transfer station, and then the sugarcane is grabbed by the grabber and loaded onto a large truck of the sugar factory.
