Technical Field

The invention belongs to the field of agricultural machinery, relates to a sugarcane harvesting machine, and particularly relates to a self-propelled double-row sugarcane combine harvester header assembly.

Background

Sugarcane is one of the main economic crops and is widely planted worldwide, and China is one of the main sugarcane producing countries. Meanwhile, the sugarcane is a perennial herbaceous plant, and can be harvested three times in one season in southern areas with appropriate climate, so that the reservation of appropriate cutting stubbles is very important in the harvesting process. At present, in a sugarcane production area in south China, hilly land accounts for more than 80% of the total planting area of the sugarcane, and the height of stubble cutting is difficult to ensure due to the fact that the ground is uneven.

Nowadays, sugarcane harvesters are used for single-row harvesting, and meanwhile, a cutter is easily influenced by the ground environment in the operation process, and a cutter head of the harvesting platform can be damaged in serious cases; in the process of harvesting, the small-part sugarcane harvester is provided with the header adjusting device, but due to unreasonable structure arrangement and high requirement on the working environment, the sugarcane harvester cannot feed back timely and accurately in the hilly land, and further cannot adjust the cutter disc to a proper position. Therefore, the labor intensity of reaping personnel is increased, the working efficiency is reduced, stubble cutting is damaged, the emergence rate of the next year is influenced, and the economic loss of sugarcane farmers is further caused. In view of the above, it is very necessary to develop a two-row sugarcane combine harvester header assembly capable of timely and accurately adjusting the position of the header to adapt to different heights and widths of the ridges.

In order to achieve the purpose, the invention adopts the technical scheme that: the header assembly of the self-propelled double-row sugarcane combine harvester comprises headers, wherein motor fixing seats are fixedly arranged at the upper parts of the headers, harvested sugarcanes are transmitted into a conveying channel by the headers, the headers are arranged in at least two groups in parallel, each group of headers is respectively and rotatably connected with the inlet end of the conveying channel through a rotating shaft, and the whole header can swing around the rotating shaft; each group of cutting tables is provided with a stubble cutting control device capable of controlling the cutting height of the sugarcane; furthermore, the stubble cutting control device comprises an adjusting bracket and rolling parts, wherein the adjusting bracket is vertically fixed on the left side and the right side of the motor fixing seat; the rolling piece is arranged below the cutter head of the sugarcane harvester, the rolling piece and the cutter head are arranged at intervals, the length of the rolling piece is the same as the width of the cutter head, a cylindrical roller is arranged at the position, corresponding to the cutter head, of the rolling piece, and two ends of the rolling piece are respectively connected with the lower portion of the adjusting support in a rotating mode through bearing assemblies.

Furthermore, the rolling part is made of metal or plastic, the rolling part comprises an intermediate shaft and two rollers sleeved on the intermediate shaft, the intermediate shaft is fixedly connected with the rollers, and two ends of the intermediate shaft are respectively rotatably connected with the lower part of the adjusting bracket through bearing assemblies.

Further, the length of the roller is the same as the width of the cutter head.

Further, the roller is positioned right below the cutter head.

Furthermore, a plurality of supporting pipes are uniformly arranged on the periphery of the outer surface of the roller.

Further, the number of the support tubes is 6-10.

Furthermore, a plurality of sliding supports are fixedly arranged at the rear part of the motor fixing seat, and the cutting table is movably connected with the rotating shaft through the sliding supports.

Furthermore, the sliding support can swing up and down around the rotating shaft and also can slide along the axial direction of the rotating shaft, so that the left and right adjustment of the header is realized.

Further, the number of the sliding supports is 2-4.

According to the invention, the following beneficial effects can be achieved:

1. each harvester is provided with two groups of cutting tables, so that two rows of sugarcanes can be harvested at the same time, and the harvesting efficiency can be doubled; every group header sets up alone, does not interfere each other, is convenient for according to sugarcane ground actual conditions, controls, height adjustment through the relative displacement of sliding support and pivot respectively to the header.

2. Because the header is connected with a stubble adjusting device, and the stubble adjusting device comprises a rolling part and an adjusting bracket, the rolling part rolls along the ground under the driving of the adjusting bracket to advance, so that the height of the header can be automatically adjusted along with the concave-convex change of the ground, the height and the width of two adjacent rows of ridges can be adapted, and the rolling part can drive the whole header to swing, so that the cutter head can always keep orderly harvesting, and the consistency of the stubble height is further ensured.

3. Because a plurality of stay tubes are evenly arranged on the outer surface of the rolling part in a circle, in the advancing process, some gravels, stones and sugarcane tops can smoothly and smoothly pass through gaps between adjacent stay tubes, so that the cutter protecting function is achieved, the cutting stubble can be quickly and effectively controlled to reach the required height, the cutting stubble is protected from being broken, the recovery rate and the germination rate are improved, the seedling supplementing workload is reduced, and the cost is reduced. Meanwhile, the height of the cutter head can be adjusted along with different heights of the ground in time in the harvesting process of the harvester, so that harvesting personnel can respond quickly, the working efficiency of the harvesting personnel is improved, the labor intensity of the harvesting personnel is reduced, and the harvesting difficulty is reduced.

4. Compared with the common single-row harvester in the prior art, the invention can improve the sugarcane harvesting efficiency by more than 1 time and reduce the annual seedling supplementing amount by 10-20%.
