Description

Technical Field

[0001] The utility model relates to the technical field of sugarcane impurity removal equipment, and more specifically, it relates to a material leveling ladder for sugarcane impurity removal equipment. Background Technique

[0002] After harvesting sugarcane, it is usually necessary to perform preprocessing such as leaf peeling and impurity removal on the sugarcane first to facilitate subsequent deep processing in a sugar factory. Most of the traditional pretreatment work is carried out manually for impurity removal, but due to its high labor intensity and low efficiency, it has gradually been replaced by mechanical impurity removal equipment. For example, a sugarcane impurity removal production line disclosed in the publication number: CN112827949A, and a cut-off type sugarcane impurity removal system disclosed in the publication number: CN218802541U. Using mechanical impurity removal equipment to replace traditional manual impurity removal can greatly improve the processing efficiency of sugarcane impurity removal.

[0003] In the existing sugarcane impurity removal equipment, the material leveling ladder mainly relies on a motor or a motor to drive the cut sugarcane segments to be lifted into a blower for impurity removal. During the conveying process of the material leveling ladder, when the conveying amount of sugarcane materials is too large, it will cause the material layer to be too thick, resulting in too low a parabola, and too much material entering the blower air duct per unit, leading to too large a resistance of the blower and affecting the impurity removal effect. Among them, the inclination angle of the material leveling ladder is an important factor determining the size of the sugarcane conveying amount. Therefore, how to reasonably set the inclination angle and layout of the material leveling ladder is a difficult problem to overcome in the current sugarcane impurity removal equipment. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is in view of the above deficiencies of the prior art. The purpose of the utility model is to provide a material leveling ladder for sugarcane impurity removal equipment, which can effectively improve the impurity removal efficiency of sugarcane, and at the same time make the structural layout of the entire sugarcane impurity removal equipment more compact and reasonable.

[0005] To achieve the above purpose, the utility model provides a material leveling ladder for sugarcane impurity removal equipment, including a material leveling ladder main body. The input port of the material leveling ladder main body extends below the discharge port of the cutting device of the sugarcane impurity removal equipment, and the output port of the material leveling ladder main body extends into the impurity removal device of the sugarcane impurity removal equipment; the included angle between the conveying direction of the material leveling ladder main body and the horizontal direction is 55° to 70°.

[0006] As a further improvement, the included angle between the conveying direction of the material leveling ladder main body and the horizontal direction is 60° to 65°.

[0007] Furthermore, a protective plate is provided on the periphery of the material leveling ladder main body.

[0008] Furthermore, the protective plate is a hollow mesh plate.

[0009] Furthermore, the conveying direction of the main body of the material leveling ladder is arranged crosswise with the discharging direction of the cutting device.

[0010] Furthermore, the main body of the material leveling ladder is a conveying mechanism with a screening function.

[0011] Furthermore, the conveying mechanism includes a support frame, chains, scraping plates, and a screen plate. Driving sprockets and driven sprockets are respectively rotatably provided at both ends of the support frame. The chains are arranged in pairs on both sides of the support frame, and the chains are sleeved between the driving sprockets and the driven sprockets. There are multiple scraping plates, and the multiple scraping plates are installed on the two chains at intervals. The screen plate is installed in the support frame. The screen plate and the scraping plate located in the upper layer are in clearance fit, and the clearance between the two is smaller than the diameter of the sugarcane.

[0012] Furthermore, the conveying mechanism includes a conveyor belt and scraping plates. The belt corresponding to the conveyor belt is a mesh rubber belt. There are multiple scraping plates, and the multiple scraping plates are installed on the belt corresponding to the conveyor belt at intervals.

[0013] Furthermore, the main body of the material leveling ladder extends obliquely upward from the lower direction of the discharging port of the cutting device towards the impurity removing device.

[0014] Furthermore, the main body of the material leveling ladder first extends horizontally from the lower direction of the discharging port of the cutting device towards the impurity removing device, and then extends obliquely upward.

[0015] Beneficial effects

[0016] Compared with the prior art, the present utility model has the following advantages:

[0017] For the material leveling ladder of the present utility model, by limiting the conveying direction of the main body of the material leveling ladder at a reasonable angle, even when a large amount of sugarcane needs to be processed per unit time, most of the sugarcane can be ensured to be within the effective conveying range. Through experiments, it is found that when conveying sugarcane for impurity removal within this conveying angle range, an impurity removal rate of more than 90% can be stably achieved, which can effectively improve the impurity removal efficiency of sugarcane. At the same time, the sizes of the cutting device and the impurity removing device matched within this conveying angle range can be correspondingly reduced, thereby reducing the volume of the entire impurity removing equipment, making the structural layout of the entire sugarcane impurity removing equipment more compact and reasonable, and facilitating transportation and transfer.

[0023] The present utility model will be further described below in conjunction with specific embodiments in the drawings.

[0024] Embodiment 1

[0025] Referring to Figures 1-3 As shown, it is a specific embodiment of the present utility model. The material leveling ladder of a sugarcane impurity removing device in this embodiment includes a main body 1 of the material leveling ladder. The input port of the main body 1 of the material leveling ladder extends below the discharge port of the cutting device 2 of the sugarcane impurity removing device, so that a height difference is formed between the cutting device 2 and the main body 1 of the material leveling ladder. The cutting device 2 is the structure of an existing sugarcane impurity removing device, which will not be elaborated here. When the sugarcane cut by the cutting device 2 falls from its discharge port, the sugarcane will impact the main body 1 of the material leveling ladder, enabling the self - carried sediment to be separated. The output port of the main body 1 of the material leveling ladder extends into the impurity removing device 3 of the sugarcane impurity removing device. Among them, the impurity removing device is the structure of an existing sugarcane impurity removing device, such as a blower, etc., located obliquely above the cutting device 2. The main body 1 of the material leveling ladder can lift the cut sugarcane into the blower for impurity removal. The included angle between the conveying direction of the main body 1 of the material leveling ladder and the horizontal direction is 55° - 70°, that is, as Figure 3 shown, the included angle α is 55° - 70°.

[0026] For the material leveling ladder of the present utility model, by limiting the conveying direction of the main body 1 of the material leveling ladder at a reasonable angle, even when a large amount of sugarcane needs to be processed per unit time, most of the sugarcane can be ensured to be within the effective conveying range. Through experiments, it is found that when conveying sugarcane for impurity removal within this conveying angle range, the impurity removal rate of more than 90% can be stably achieved, which can effectively improve the impurity removal efficiency of sugarcane. At the same time, the sizes of the cutting device and the impurity removing device supporting within this conveying angle range can be correspondingly reduced, thereby reducing the volume of the entire impurity removing device, making the structural layout of the entire sugarcane impurity removing device more compact and reasonable, and facilitating transportation and transfer.

[0027] Preferably, in this embodiment, the included angle between the conveying direction of the main body 1 of the material leveling ladder and the horizontal direction is preferably 60° - 65°, and the corresponding sugarcane conveying effect at this angle is the best.

[0028] Preferably, a protective plate 4 is provided on the outer periphery of the material leveling ladder main body 1. The setting of the protective plate 4 can prevent sugarcane from falling and ensure that the sugarcane can fall into the material leveling ladder main body 1. Further, the protective plate 4 is a hollow mesh plate. The hollow protective plate 4 can meet the protection requirements. Once the sugarcane hits the protective plate 4, the sediment can also be separated through the mesh holes of the hollow mesh plate, achieving a certain effect of removing sediment and also playing a role in weight reduction.

[0029] Preferably, the conveying direction of the material leveling ladder main body 1 is arranged crosswise with the discharging direction of the cutting device 2. When the cut sugarcane falls into the material leveling ladder main body 1 moving in a different direction, the impact force on the sugarcane is greater and the direction changes, making the sediment on the sugarcane more likely to fall off, further improving the sediment removal effect. In this embodiment, the conveying direction of the material leveling ladder main body 1 and the discharging direction of the cutting device 2 are preferably arranged vertically, which can further improve the sediment removal effect and at the same time reduce the volume of the entire impurity removal device.

[0030] Preferably, the material leveling ladder main body 1 is a conveying mechanism with a screening function, and the sediment separated when the sugarcane hits the material leveling ladder main body 1 can be screened out by itself. Specifically, the conveying mechanism includes a support frame 5, a chain 6, a scraper 7 and a screen plate 8. Among them, the support frame 5 is detachably connected to the cutting device 2 by bolts to realize the fixed installation of the material leveling ladder main body 1. A driving sprocket and a driven sprocket are respectively rotatably provided at both ends of the support frame 5. The chains 6 are arranged in pairs on both sides of the support frame 5, and the chains 6 are sleeved between the driving sprocket and the driven sprocket. There are multiple scrapers 7, and the multiple scrapers 7 are installed at intervals on the two chains 6 to form a scraper conveyor. The driving sprocket is driven to rotate by a hydraulic motor. A number of mesh holes are provided on the surface of the screen plate 8. The screen plate 8 is installed in the support frame 5 (that is, the screen plate 8 is located between the upper and lower layers of scrapers 7), and the screen plate 8 extends along the length direction of the support frame 5. The screen plate 8 and the scraper 7 located on the upper layer are in clearance fit, and the clearance between the two is smaller than the diameter of the sugarcane, which meets the sliding requirement of the scraper 7 and avoids the problem of interference between the scraper 7 and the screen plate 8, and at the same time can prevent the problem of sugarcane falling. In the material leveling ladder main body of this embodiment, during use, when the sugarcane falls on the screen plate 8, the sugarcane hits the screen plate 8, and the sediment can fall from the mesh holes, thereby realizing the removal of sediment. At the same time, when the sugarcane is driven by the scraper 7 to move, the sediment can also be removed as the sugarcane moves.

[0031] In other embodiments, the conveying mechanism includes a conveyor belt and a scraper 7. Among them, the belt corresponding to the conveyor belt is a mesh rubber belt. There are multiple scrapers 7, and the multiple scrapers 7 are installed at intervals on the belt corresponding to the conveyor belt. The conveyor belt is driven to rotate by a hydraulic motor. During use, when the sugarcane falls on the belt corresponding to the conveyor belt, the sugarcane hits the belt, and the sediment can fall from the mesh holes of the belt, thereby realizing the removal of sediment, and the purpose of screening function can also be achieved.

[0032] In this embodiment, as Figure 3 shown, the main body 1 of the material leveling ladder first extends horizontally downward from the discharge port of the cutting device 2 in the direction of the impurity removing device 3, and then extends obliquely upward, in the form of a folding ladder. The main body 1 of the material leveling ladder in this embodiment is a horizontal conveyor at the position corresponding to the discharge port of the cutting device 2, forming a hopper structure with an increased storage space, effectively coping with the processing of a large amount of materials instantaneously.

[0033] Embodiment 2

[0034] Refer to Figure 4 , which is another specific embodiment of the present invention. This embodiment is basically the same as Embodiment 1, and the difference is that the main body 1 of the material leveling ladder extends obliquely upward from the discharge port of the cutting device 2 in the direction of the impurity removing device 3, in the form of a straight ladder. The structure of the straight ladder simplifies the assembly process.

[0035] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
