Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a sugarcane conveying device. Background Technology

[0002] Traditional sugarcane harvesting has long relied primarily on manual labor for processes such as felling and leaf stripping, followed by transporting the processed sugarcane to sugar mills. However, this traditional model has revealed numerous drawbacks: ① Inefficiency: Over-reliance on manual labor, slow operation, and inability to meet the demands of large-scale planting; ② High costs: High labor demand, with labor costs accounting for over 50% of the total sugarcane production cost. Furthermore, with urbanization, there has been a significant loss of labor in major sugarcane-producing areas, and sugar mills are increasingly demanding higher quality raw materials, making it difficult for traditional technologies to meet standardized requirements.

[0003] To address the aforementioned problems, reduce reliance on manual labor, and improve harvesting efficiency, mechanized sugarcane harvesting technology has emerged and is gradually replacing traditional harvesting methods. Depending on the harvesting machinery used, mechanized sugarcane harvesting technology has diversified. One widely adopted mechanized harvesting technology involves the following process: First, sugarcane, leaves and all, is felled by machinery and then transported to a centralized sugarcane processing station. At the station, a crane lifts the sugarcane with leaves to a feeding platform, where it is then conveyed into sugarcane cleaning (i.e., leaf stripping and cutting) equipment. In this equipment, the leaf stripping unit removes the leaves, while the cutting unit cuts the sugarcane into sections. Finally, the cut sugarcane is transported to a sugar mill for processing. This technology integrates mechanized harvesting, leaf stripping, and cutting functions, effectively improving the overall efficiency of sugarcane harvesting and processing.

[0004] However, existing sugarcane mechanization technologies still have certain limitations in practical applications. Specifically, after the sugarcane with leaves is lifted onto the feeding platform by a crane, it falls directly onto the conveyor, resulting in uneven thickness of the sugarcane spread on the conveyor. Conventional conveyor systems only have a transport function and lack the ability to adjust the thickness of the sugarcane spread. Therefore, when the sugarcane enters the cleaning equipment, it still maintains its initial uneven thickness on the conveyor. This uneven thickness will adversely affect the efficiency of subsequent leaf stripping and cutting.

[0005] Therefore, there is an urgent need to develop a conveying device that combines transportation and adjustment of sugarcane laying thickness to solve the problem of reduced efficiency in subsequent leaf stripping and cutting caused by uneven sugarcane laying thickness. Summary of the Invention

[0006] This utility model provides a sugarcane impurity removal and conveying device, which combines the functions of transporting and adjusting the thickness of sugarcane laying, thereby solving the problem of reduced efficiency in subsequent leaf stripping and cutting caused by uneven sugarcane laying thickness.

[0007] To solve the above problems, the technical solution adopted by this utility model is:

[0008] It includes a frame on which a conveyor belt is mounted via conveyor rollers; along the conveying direction of the conveyor belt, an adjusting roller is provided above the front end of the conveyor belt, the adjusting roller being mounted above the conveyor belt via supports mounted on both sides of the conveyor belt and bearings mounted on the supports, and perpendicular to the conveying direction of the conveyor belt; the adjusting roller is connected to a drive motor, which is mounted on one side of the conveyor belt; the adjusting roller includes adjusting roller one and adjusting roller two, the middle section of the adjusting roller body is a cylindrical structure and the two ends are frustoconical structures, the small end of the frustoconical structure is connected to the cylindrical structure; the adjusting roller two has a double frustoconical structure with the large end connected.

[0009] A more specific technical solution to the above technical solution may be: the diameter of the cylindrical structure in the middle section of the first adjusting roller is 20cm and the length is 40cm, and the large end diameter of the frustum-shaped structure at both ends is 30cm, the small end diameter is 20cm and the length is 30cm; the large end diameter of the double frustum-shaped structure of the second adjusting roller is 30cm, the small end diameter is 20cm and the length is 40cm.

[0010] Furthermore, along the conveying direction of the conveyor belt, the first adjusting roller is installed in front of the second adjusting roller.

[0011] Furthermore, the distance between the first adjusting roller and the second adjusting roller is 76cm.

[0012] Furthermore, the vertical distance between the middle section of the first adjusting roller and the conveyor belt is 15cm; the vertical distance between the large end of the second adjusting roller (double-conical shape) and the conveyor belt is 10cm.

[0013] Furthermore, baffles are provided on both sides of the end of the conveyor belt, and the baffles are inclined in an inverted octagonal shape on both sides of the end of the conveyor belt.

[0014] Furthermore, the two side baffles on both sides of the end of the conveyor belt have one side baffle being higher than the other side baffle.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0016] 1. This utility model can efficiently and precisely adjust the thickness of sugarcane laid on a conveyor belt, effectively improving the efficiency and quality of sugarcane transportation and subsequent processing. It achieves this by adding two adjusting rollers above the front end of the conveyor belt. Through the synergistic effect of these two rollers, the thickness of the sugarcane laid on the conveyor belt can be precisely controlled, ensuring a uniform and consistent laying effect after the sugarcane passes through the adjusting rollers. One of the adjusting rollers adopts a unique segmented design, with a cylindrical structure in the middle and frustum-shaped structures at both ends. The smaller end of the frustum-shaped structure seamlessly connects with the cylindrical structure. The special structure allows the frustum-shaped sections at both ends of the roller to cleverly guide the thicker parts on both sides of the sugarcane pile towards the middle of the conveyor belt as the sugarcane passes through, thus achieving an initial uniform distribution of sugarcane in the width direction of the conveyor belt. The other adjusting roller adopts a unique structure with a double frustum-shaped large end joint. When the sugarcane passes through this adjusting roller, the "groove" area formed in the middle of the roller guides the thicker sugarcane in the middle of the conveyor belt to flow to both sides. This works in conjunction with the first adjusting roller to further optimize the uniformity of sugarcane distribution on the conveyor belt.

[0017] 2. This utility model limits the size parameters of the two adjusting rollers, their installation height with the conveyor belt, and the installation distance between them according to the feeding thickness required by the subsequent peeling and cutting process of sugarcane, thereby improving the efficiency of the subsequent peeling and cutting process of sugarcane.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings: Example

[0025] like Figure 1-5 As shown, a sugarcane impurity removal and conveying device includes a frame 1, on which a conveyor belt 3 is mounted via conveyor rollers 2. Along the conveying direction of the conveyor belt 3, an adjusting roller 5 is positioned above the front end of the conveyor belt 3. The adjusting roller 5 is mounted above the conveyor belt 3 via supports 6 mounted on both sides of the conveyor belt 3 and bearings 7 mounted on the supports 6, and is perpendicular to the conveying direction of the conveyor belt 3. The adjusting roller 5 is connected to a drive motor 8, which is mounted on one side of the conveyor belt 3. The adjusting roller 5 includes an adjusting roller 1 5-1 and an adjusting roller 2 5-2. The middle section of the adjusting roller 1 5-1 has a cylindrical structure, and both ends have frustum-shaped structures. The small end of the frustum-shaped structure is connected to the cylindrical structure. This special structure allows the frustum-shaped portions at both ends of the roller to cleverly guide and move the thicker portions on both sides of the sugarcane pile towards the middle of the conveyor belt 3 when the sugarcane passes through the adjusting roller 5-1, thereby achieving a preliminary uniform distribution of the sugarcane in the width direction of the conveyor belt 3. The regulating roller 5-2 has a double-conical, large-end-joint structure. This special structure allows the "groove" area formed in the middle of the roller body to guide the thicker sugarcane in the middle of the conveyor belt 3 to flow to both sides when the sugarcane passes through it. This works in conjunction with the previous regulating roller 5-1 to further optimize the uniformity of sugarcane distribution on the conveyor belt 3. In other words, by adding two regulating rollers 5 above the front end of the conveyor belt 3, the thickness of the sugarcane distribution on the conveyor belt 3 can be precisely controlled through the synergistic effect of these two regulating rollers 5, ensuring a uniform distribution of sugarcane after passing through the regulating rollers 5.

[0026] Preferably, in order to further improve the efficiency of subsequent peeling and cutting of sugarcane, the size parameters of the two adjusting rollers 5 themselves, their installation height with the conveyor belt 3, and the installation distance between them can be further limited according to the feeding thickness required by the subsequent peeling and cutting process of sugarcane. Specifically, the diameter of the cylindrical structure in the middle section of adjusting roller 5-1 is limited to 20cm and the length to 40cm, and the large end diameter of each frustum structure at both ends is limited to 30cm, the small end diameter to 20cm, and the length to 30cm; the large end diameter of each frustum in the double frustum structure of adjusting roller 5-2 is limited to 30cm, the small end diameter to 20cm, and the length to 40cm.

[0027] The distance between adjusting roller 1 5-1 (i.e. its cylindrical structure) and adjusting roller 2 5-2 (i.e. its double-conical large end joint) is 76cm.

[0028] The vertical distance between the middle section of the adjusting roller 1 5-1 and the conveyor belt 3 is 15cm; the vertical distance between the large end of the double-cone truncated roller 2 5-2 and the conveyor belt 3 is 10cm.

[0029] Preferably, to make the entire conveying process smoother, the adjusting roller 5-1 can be installed in front of the adjusting roller 5-2 along the conveying direction of the conveyor belt 3. If the adjusting roller 5-2 is placed in front, because its roller body has a double-cone truncated cone shape with the large end joined, it may not be able to effectively gather and organize the sugarcane as effectively as the adjusting roller 5-1 in the initial stage, which may easily cause the sugarcane to accumulate at the front end of the conveyor belt 3, affecting the conveying efficiency and the conveying quality of the sugarcane. However, by having the adjusting roller 5-1 play its role first, this situation can be effectively avoided.

[0030] Preferably, in order to prevent sugarcane falling from the feeding platform onto the conveyor belt 3 from falling off both sides of the conveyor belt 3, baffles 4 can be provided on both sides of the end of the conveyor belt 3, and the baffles 4 are inclined in an inverted V shape on both sides of the end of the conveyor belt 3.

[0031] Preferably, the two side baffles 4 on both sides of the end of the conveyor belt 3 can be configured such that the height of one side baffle is higher than the height of the other side baffle, and the side baffle with the lower height is located below the sugarcane feeding platform.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
