Description

Technical Field

[0001] The utility model relates to the technical field of sugarcane impurity removal equipment, and more specifically, it relates to a cutting device for sugarcane impurity removal equipment. Background Art

[0002] After harvesting sugarcane, it is usually necessary to carry out pre-processing such as leaf peeling and impurity removal on the sugarcane to facilitate subsequent deep processing in the sugar factory. Most of the traditional pre-processing 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is carried out manually for impurity removal, but due to its high labor intensity and low efficiency, it has gradually been replaced by mechanical impurity removal equipment.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 cutting type sugarcane impurity removal system disclosed in the publication number: CN218802541U, which use 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, multiple groups of sugarcane conveying rollers are generally used for conveying, such as a sugarcane feeding and cutting device parallel hydraulic system disclosed in the publication number: CN221257280U. Its sugarcane impurity removal equipment uses at least two groups of sugarcane conveying rollers at the front end for conveying, aiming to let sediment naturally leak during the conveying process. However, this design has obvious defects: too many conveying rollers increase the stress points of sugarcane while easily causing unnecessary extrusion, breakage or damage to sugarcane during the conveying process, not only reducing the subsequent processing quality of sugarcane, but also affecting the overall impurity removal efficiency and economic benefits.

[0004] Therefore, it is urgent to design a cutting device for sugarcane impurity removal equipment to solve the above problems. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is aimed at the above deficiencies of the prior art. The purpose of the utility model is to provide a cutting device for sugarcane impurity removal equipment, which reduces the number of conveying rollers and simplifies the assembly process while ensuring that the impurity removal effect of the whole machine is not affected, and at the same time improves the integrity and quality of sugarcane cutting.

[0006] To achieve the above purpose, the utility model provides a cutting device for sugarcane impurity removal equipment, including a frame. A cutting roller and a conveying roller are rotatably installed in the frame. The conveying roller is a single group, and a cleaning mechanism for removing sediment is integrally arranged on the frame on the side opposite to the conveying roller.

[0007] As a further improvement, the conveying roller includes a floating roller and a fixed roller. The floating roller and the fixed roller are symmetrically arranged up and down in the frame, and both the floating roller and the fixed roller are driven to rotate by a hydraulic motor.

[0008] Further, the cutting rollers are a set, including a first cutting roller and a second cutting roller. The first cutting roller and the second cutting roller are symmetrically arranged up and down in the frame, and both the first cutting roller and the second cutting roller are driven to rotate by a hydraulic motor.

[0009] Further, the cleaning mechanism is detachably connected to the frame.

[0010] Further, the cleaning mechanism is a leveling ladder with a screening function. The input port of the leveling ladder extends below the discharge port of the cutting roller, and the conveying direction of the leveling ladder is arranged crosswise with the discharge direction of the cutting roller.

[0011] Further, the leveling ladder 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 sprocket and the driven sprocket. 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] Further, a protective plate is provided on the support frame corresponding to the position of the discharge port of the cutting roller.

[0013] Further, the protective plate is a hollow mesh plate.

[0014] Further, a reinforcing component for reinforcing the feeding ladder is also provided on the frame.

[0015] Further, the reinforcing component includes a limiting plate. One end of the limiting plate is hinged and installed on the frame, and a clamping groove is provided at the other end.

[0016] Beneficial effects

[0017] Compared with the prior art, the present utility model has the following advantages:

[0018] In the cutting device of the present utility model, by providing a cleaning mechanism for removing sediment on one side of the discharge port of the cutting roller, the cleaning mechanism for sediment is integrated in the cutting device and placed behind the cutting roller. In this way, only a set of conveying rollers needs to be arranged at the feeding port of the cutting roller to meet the requirement of conveying the sugarcane into the cutting roller for cutting. The arrangement method of placing the sediment cleaning process behind in this cutting device reduces the number of conveying rollers and simplifies the assembly process while ensuring that the impurity removal effect of the whole machine is not affected. At the same time, the integrity and quality of sugarcane cutting are improved. Description of the drawings

[0023] The following further describes the present utility model with reference to specific embodiments in the drawings.

[0024] Refer to Figures 1-3 As shown, a cutting device of a sugarcane impurity removal device includes a frame 1. A cutting roller and a conveying roller are rotatably installed in the frame 1. Among them, the cutting roller is used to cut sugarcane, and the conveying roller is used to convey sugarcane into the cutting roller. Specifically, there is a group of conveying rollers, that is, there is only one group of conveying rollers. A cleaning mechanism for removing sediment is also integrally provided on the frame 1 on the side opposite to the conveying roller, that is, the cleaning mechanism is arranged at the position corresponding to the discharge port of the cutting roller, so that sediment can be removed immediately after the sugarcane is cut. Specifically, the conveying rollers include a floating roller 2 and a fixed roller 3. Among them, the floating roller 2 and the fixed roller 3 are symmetrically arranged up and down in the frame 1, and both the floating roller 2 and the fixed roller 3 are driven to rotate by a hydraulic motor. The cutting rollers are a group, including a first cutting roller 4 and a second cutting roller 5. The first cutting roller 4 and the second cutting roller 5 are symmetrically arranged up and down in the frame 1, and both the first cutting roller 4 and the second cutting roller 5 are driven to rotate by a hydraulic motor. The specific structures and installation methods of the cutting roller and the conveying roller are all prior arts and will not be elaborated here.

[0025] In the cutting device of the present utility model, a cleaning mechanism for removing sediment is arranged on one side of the discharge port of the cutting roller. The sediment cleaning mechanism is integrated in the cutting device and is placed behind the cutting roller. In this way, only one group of conveying rollers can be arranged at the feeding port of the cutting roller to meet the requirement of conveying sugarcane into the cutting roller for cutting. The arrangement method of placing the sediment cleaning process behind in this cutting device reduces the number of conveying rollers and simplifies the assembly process while ensuring that the impurity removal effect of the whole machine is not affected. At the same time, the integrity and quality of sugarcane cutting are improved.

[0026] Preferably, the cleaning mechanism is detachably connected to the frame 1. Specifically, the cleaning mechanism and the frame 1 can be connected by bolting or by a snap connection. The detachable cleaning mechanism is convenient for disassembly, installation and maintenance.

[0027] Preferably, the cleaning mechanism is a material leveling ladder with a screening function, such as Figure 2 and 3 As shown, the input port of the material leveling ladder extends to below the discharge port of the cutting roller, and the conveying direction of the material leveling ladder is arranged crosswise with the discharge direction of the cutting roller. When the cut sugarcane falls into the material leveling ladder moving in different directions, the impact force on the sugarcane is greater and the direction changes, making it easier for the silt on the sugarcane to fall off, further improving the silt removal effect. In this embodiment, the conveying direction of the material leveling ladder and the discharge direction of the cutting roller are preferably arranged vertically, which can further improve the silt removal effect and reduce the volume of the entire impurity removal equipment. Furthermore, the material leveling ladder includes a support frame 6, a chain 11, a scraper 12 and a screen plate 7, wherein the support frame 6 is detachably connected to the frame 1 by bolts to achieve fixed installation of the material leveling ladder, and a driving sprocket and a driven sprocket are rotatably provided at both ends of the support frame 6, and the chains 11 are arranged in pairs on both sides of the support frame 6, and the chains 11 are sleeved between the driving sprocket and the driven sprocket, there are multiple scrapers 12, and multiple scrapers 12 are installed on two chains 11 at intervals to form a scraper conveyor, and the driving sprocket is driven to rotate by a hydraulic motor, and a plurality of mesh holes are opened on the surface of the screen plate 7, and the screen plate 7 is installed in the support frame 6 (that is, the screen plate 7 is located between the upper and lower layers of scrapers 12), and the screen plate 7 extends along the length direction of the support frame 6, and the screen plate 7 and the scraper 12 located on the upper layer are gap-matched, and the gap between the two is smaller than the diameter of the sugarcane, which meets the sliding needs of the scraper 12, avoids the problem of interference between the scraper 12 and the screen plate 7, and prevents the problem of sugarcane falling. In the material leveling ladder of this embodiment, when sugar cane falls on the screen plate 7 during use, the sugar cane collides with the screen plate 7, and the mud and sand can fall from the mesh holes, thereby removing the mud and sand. At the same time, when the scraper 12 is moved, the mud and sand can also be removed with the movement of the sugar cane. In other embodiments, the material leveling ladder can also include a conveyor belt and a scraper, the belt corresponding to the conveyor belt is a mesh rubber belt, there are multiple scrapers, and the multiple scrapers are installed at intervals on the belt corresponding to the conveyor belt, and the conveyor belt is driven to rotate by a hydraulic motor. During use, when sugar cane falls on the belt corresponding to the conveyor belt, the sugar cane collides with the belt, and the mud and sand can fall from the mesh holes of the belt, thereby removing the mud and sand, and the purpose of the screening function can also be achieved.

[0028] Preferably, a protective plate 8 is provided on the support frame 6 corresponding to the discharge port of the cutting roller. The provision of the protective plate 8 can prevent the sugarcane from falling and ensure that the sugarcane can fall into the screen plate 7 corresponding to the material leveling ladder. Furthermore, the protective plate 8 is a hollow screen plate. The hollow protective plate 8 not only meets the protection requirements, but also, once the sugarcane hits the protective plate 8, its mud and sand can be separated out through the mesh of the hollow screen plate, which has a certain effect of removing mud and sand, and can also play a role in weight reduction.

[0029] Preferably, Figure 1 and3 As shown in the figure, a reinforcement component for strengthening the feeding ladder 9 is further provided on the frame 1. The reinforcement components are arranged in pairs on both sides of the frame 1. When the whole impurity removal device is installed, the reinforcement components can be used to connect with the feeding ladder 9 to improve the stability of the feeding ladder 9. Further, the reinforcement component includes a limiting plate 10. One end of the limiting plate 10 is hinged to the frame 1, and a clamping groove is provided at the other end. The reinforcement component adopts a swinging structure. When the feeding ladder 9 is folded and stored on the frame 1, it can rotate to make way for it, so as to facilitate the folding and storage of the feeding ladder 9 and avoid interference problems, making it more convenient to use.

[0030] The above is only the preferred embodiment 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 implementation effect of the present invention and the practicability of the patent.
