Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically a straight dual-channel double-row sugarcane harvester. Background Technology

[0002] Traditional sugarcane harvesters have a single-channel sugarcane conveying structure, which can only harvest and convey single rows of sugarcane with a certain planting row spacing, resulting in slow harvesting efficiency. Multi-row sugarcane harvesters need to harvest two or more rows of sugarcane at the same time. The single-channel conveying structure is not conducive to feeding multiple rows of sugarcane at the same time. Furthermore, the application of the single-channel conveying structure in double-row sugarcane harvesters will increase the overall size of the structure, making it more difficult and costly to manufacture, and resulting in poor maintenance convenience. It also places higher demands on the strength of the structure and the main frame structure.

[0003] The shortcomings of existing technology are:

[0004] 1. A single-row harvester can only harvest one row of sugarcane, which is inefficient and cannot be adapted to large-scale farm harvesting operations. A dual-row structure can harvest two rows of sugarcane at the same time, doubling the machine harvesting efficiency.

[0005] 2. When conveying a single row of sugarcane in a single-row channel, the maximum conveying capacity of the rear channel is too large than the feed capacity, resulting in low sugarcane conveying efficiency and energy waste.

[0006] Although some patents disclose sugarcane harvesters with dual channels, such as CN201711171048.9 and CN202021871931.6, their channels are mostly arc-shaped or inclined dual channels, which still have the problem of easy blockage and accumulation of material.

[0007] The information disclosed in the above background section is only intended to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Utility Model Content

[0008] In view of the above-mentioned defects, the purpose of this utility model is to provide a straight double-channel double-row sugarcane harvester to solve the problems of easy blockage and material accumulation in arc-shaped double-channel and oblique double-channel harvesters.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A double-row sugarcane harvester with a dual-conveyor straight channel includes a front channel pressing roller, a front channel header assembly, a front channel conveyor roller, a converging rear channel, a cutting device, and a cleaning fan arranged in a straight line from front to back. The front channel pressing roller includes a left pressing roller and a right pressing roller, which respectively act on two rows of sugarcane. The front channel header assembly includes a left header assembly and a right header assembly. The front channel conveyor roller includes a left conveyor roller group and a right conveyor roller group. The converging rear channel is trapezoidal in shape, wider at the front and narrower at the back. The outlets of the left and right pressing rollers are respectively connected to the left and right header assemblies. The outlets of the left and right header assemblies are respectively connected to the left and right conveyor roller groups. The outlets of the left and right conveyor roller groups are connected to the converging rear channel. The outlet of the converging rear channel is connected to the cutting device. The outlet of the cutting device is connected to the cleaning fan.

[0011] Furthermore, the left and right pressing rollers have the same structure, both consisting of a first pressing roller and a second pressing roller arranged in parallel.

[0012] Furthermore, the left conveying roller group and the right conveying roller group have the same structure, both consisting of a first lifting roller, a second lifting roller, and a third lifting roller arranged sequentially from front to back, and a first floating roller, a second floating roller, and a third floating roller arranged parallel above them.

[0013] Furthermore, the convergent rear channel includes a fourth lifting roller, a fifth lifting roller, a sixth lifting roller, a seventh lifting roller, and an eighth lifting roller arranged sequentially from front to back, and a fourth floating roller, a fifth floating roller, a sixth floating roller, a seventh floating roller, and an eighth floating roller arranged parallel above it. The fourth lifting roller, the fifth lifting roller, the sixth lifting roller, the seventh lifting roller, the eighth lifting roller, and the fourth, fifth, sixth, seventh, and eighth floating rollers are arranged sequentially from front to back, and their lengths decrease sequentially, thus forming a convergent channel.

[0014] Furthermore, the impurity removal fan includes a duct and fan blades located inside the duct. It is used to collect and remove impurities from the gathered sugarcane.

[0015] Furthermore, the front channel conveying roller and the converged rear channel are hinged together by a hinge point.

[0016] The working principle of this utility model is as follows: Due to the straight structural layout, the axes of the pressing rollers on both sides of the channel are parallel. The front channel conveying rollers, including the first, second, and third lifting rollers and the floating roller, are distributed on both sides, with their axes parallel to each other and parallel to the axis of the pressing rollers. The converging rear channel, including the fourth lifting roller and the fourth floating roller, is distributed on both sides, with their axes parallel to each other. The fifth, sixth, seventh, and eighth lifting rollers and the floating roller are mounted on the frame, with their axes parallel to each other. The lengths of conveying rollers at the same level are equal, while the lengths of the front and rear conveying rollers decrease progressively. For example, the fifth lifting roller and the fifth floating roller are equal in length and longer than the sixth lifting roller and the floating roller. This decreasing length forms a converging structure, gathering the sugarcane for cutting and impurity removal.

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

[0018] This invention addresses the issue that a single-row harvesting channel can only harvest a single row of sugarcane, resulting in low efficiency and making it unsuitable for large-scale farm harvesting operations. The dual-channel structure, on the other hand, can harvest two rows of sugarcane simultaneously, doubling the machine harvesting efficiency.

[0019] When conveying a single row of sugarcane in a single-row channel, the maximum conveying capacity of the rear channel is too large than the feed capacity, resulting in low sugarcane conveying efficiency and energy waste. However, the retractable rear channel structure makes full use of the conveying capacity, improves operating efficiency, and reduces energy loss.

[0020] The straight dual-channel design maximizes the sugarcane feeding capacity and solves the problems of easy clogging and material accumulation in the arc-shaped and inclined dual-channel designs.

[0021] The retractable rear channel structure makes full use of the conveying capacity and, in conjunction with the impurity removal fan, maximizes the impurity removal capability. Attached Figure Description
