Description

High-efficiency double-row whole-rod type sugarcane combine harvester

Technical Field

The invention relates to a sugarcane harvester related device, in particular to a high-efficiency double-row whole-rod sugarcane combine harvester.

Background

Sugarcane is an important economic crop and is a main raw material in the sugar industry. China is the third world of big sugar production and consumption next to Brazil and India. The sugar is one of four important agricultural products and three economic crops in China and is an important strategic substance for the county of China. The main raw material of sugar in China is sugarcane, the planting area accounts for more than 85% of the sugar area, and the sucrose yield accounts for more than 90% of the total sugar yield.

The planting area of the sugarcane in China reaches more than 100 million hectares, the sugarcane yield is very high, and the sugarcane harvesting workload is also huge. At present, sugarcane harvesting in China mainly adopts manual cutting as a main mode, a small part of areas are mechanical harvesting, and the mechanical harvesting is also basically a semi-automatic mode or a cutting type combined harvester mode.

However, with the development of society, people who are willing to do physical work are less and less, the labor cost is higher and higher, and the cost for manually harvesting the sugarcane is higher and higher. Meanwhile, the sugarcane is harvested in a certain seasonality mode, the harvesting time is also in a node requirement, and the harvesting efficiency is low and cannot meet the requirement. The semi-automatic machinery can reduce part of manual workload when harvesting the sugarcane, but the harvesting cost is still higher, and the harvesting efficiency is still lower.

The cutting-off type combine harvester has the cutting-off mode that the whole sugarcane is cut into a plurality of small sections, and the sugarcane cutting-off efficiency is higher. However, the sugar loss rate of the sugar cane harvested by the cut-off type combine harvester is high, and large waste is caused. Moreover, the sugar canes must be sent to a sugar mill within 24 hours after being cut into small pieces to be squeezed, otherwise, the sugar canes cannot be used for deterioration, so that the sugar mill cannot guarantee that the sugar cane is squeezed from all the sugar canes if the sugar canes are cut more, and the sugar canes which are not squeezed are all wasted.

The single-row combine harvester is low in harvesting efficiency, is easily affected by uneven terrain, and is prone to side turning during the travelling process, so that danger is caused. The leaves of the sugarcane harvested by the existing harvester cannot be peeled off cleanly, the sugar squeezing of a sugar factory is influenced, and the recovery price of the sugarcane in the sugar factory is reduced. The existing harvester is easy to cause sugarcane splitting and abnormal fracture during harvesting, sugar loss of the sugarcane is caused, and the recovery price of the sugarcane in a sugar factory is reduced. The prior harvester is easy to damage the perennial roots of the sugarcane when harvesting, and influences the normal growth of the sugarcane in the next year. The conventional harvester is easy to block and jam sugarcane when the sugarcane is harvested, and the normal work of equipment is influenced. The existing harvester is large and heavy, and has poor adaptability to smaller sugarcane plots.

When the leaf peeling machine works, the first upper leaf peeling shaft, the second upper leaf peeling shaft, the third upper leaf peeling shaft, the fourth upper leaf peeling shaft, the fifth upper leaf peeling shaft, the sixth upper leaf peeling shaft, the seventh upper leaf peeling shaft, the eighth lower leaf peeling shaft and the ninth upper leaf peeling shaft rotate anticlockwise, the first lower leaf peeling shaft, the second lower leaf peeling shaft, the third lower leaf peeling shaft, the fourth lower leaf peeling shaft, the fifth lower leaf peeling shaft, the sixth lower leaf peeling shaft, the seventh lower leaf peeling shaft, the eighth upper leaf peeling shaft and the ninth lower leaf peeling shaft rotate clockwise, a driving device is arranged on the first upper leaf peeling shaft, the third upper leaf peeling shaft, the sixth lower leaf peeling shaft and the ninth upper leaf peeling shaft, and the rest shafts are driven shafts; the reason that the number eight upper leaf peeling shafts and the number eight lower leaf peeling shafts are different from other leaf peeling shafts in rotation direction is that the other leaf peeling shafts are used for conveying and peeling leaves, and the number eight upper leaf peeling shafts and the number eight lower leaf peeling shafts are used for separating sugarcane leaves from sugarcane; the beef tendon rubber material has better flexibility and wear resistance and longer service life;

the first-stage conveying and leaf stripping device adopts a splayed horn mouth feeding structure, can carry out high-efficiency conveying of double rows of sugarcanes once, and can evenly and stably transit the disordered sugarcanes into the second-stage conveying and leaf stripping device. The two-stage conveying and leaf stripping device can be used for efficiently conveying double-row sugarcanes at one time, and when the two-stage conveying and leaf stripping device is used for conveying the curved sugarcanes, the space is wide, the sugarcanes are not easy to break, and the conveying device cannot be blocked.

The arc-shaped teeth of the sugarcane peeling rubber plate can be in double-line contact with the outer circle of the sugarcane stalk, so that the contact area is increased, the leaf peeling capacity is improved, the speed of the sugarcane stalk throwing out of the conveying device is improved, the sugarcane stalk and sugarcane leaves have different conveying speeds due to different specific gravities, the sugarcane leaf speed is lower, the sugarcane stalk speed is higher, the sugarcane stalk and the sugarcane leaves are separated, the double-line contact has a function of straightening the sugarcane, the sugarcane which is inclined in the conveying device is straightened, the regular placement of the sugarcane in a sugarcane bin is ensured, and the secondary transportation of the sugarcane is facilitated;

the tip cutting rotating shaft is driven by the tip cutting motor, the cutting speed and the cutting direction are controlled by controlling the rotating speed and the steering of the tip cutting motor, and the tip cutting rubber rods arranged on the tip cutting rotating shaft can accurately break the sugarcane tips from the sugarcane growing points to damage the sugarcanes and can instantly break the broken sugarcane tips at the same time because the sugarcane growing points are fragile. The arc-shaped guard plate behind the tip cutting rotating shaft shields sundries such as crushed sugarcane leaves and sugarcane sections, and prevents the sundries from being thrown onto a windshield of a cab. The side guard plate is used for smoothing sugarcane in the range to enter the tip cutting mechanism for tip cutting. The tip cutting support base bears the whole set of structure, and the height of the tip cutting is determined by adjusting the tip cutting support jack.

The invention has the following beneficial effects: by utilizing reasonable structural design, the harvesting operations of tip cutting, cane supporting, leaf peeling, conveying and the like of the double-row whole-stalk canes are realized. The sugarcane harvester reduces the labor intensity of workers, improves the sugarcane harvesting efficiency, reduces the sugarcane harvesting cost, realizes the whole-process mechanical harvesting, reduces the manual input, avoids a cut-off type sugarcane harvesting mode, reduces the loss rate of sugarcane sugar and reduces the waste of sugarcane; the novel tip cutting device effectively reduces the impurity rate of the harvested sugarcane. The structural design is optimized, the stability of the combine harvester is improved, and the potential safety hazard of side turning is reduced; the leaf stripping capability is improved, so that the sugarcane leaves are removed more cleanly; the probability of the occurrence of splitting and abnormal breaking of the sugarcane in the harvesting process is reduced; the damage to the perennial roots of the sugarcane is reduced; abnormal phenomena such as blockage and blockage of sugarcane during harvesting are avoided; the overall appearance structure size is reduced, so that the sugarcane harvester is more suitable for harvesting sugarcane small plots.
