Description

Technical Field

[0001] This utility model relates to the technical field of sugarcane impurity removal equipment, and more specifically, it relates to a novel folding feeding ladder and a mobile sugarcane impurity removal device. Background Technology

[0002] After sugarcane is harvested, it typically undergoes pre-processing such as leaf removal and impurity removal to facilitate further processing in sugar mills. Traditionally, this pre-processing is mostly done manually, but due to its high labor intensity and low efficiency, it has been gradually replaced by mechanical impurity removal equipment. For example, a sugarcane impurity removal production line disclosed in CN112827949A and a cutting-type sugarcane impurity removal system disclosed in CN218802541U utilize mechanical impurity removal equipment to replace traditional manual impurity removal, significantly improving the processing efficiency of sugarcane impurity removal.

[0003] The key workstation in sugarcane pretreatment for impurity removal equipment, and its crucial component—the feeding ladder, typically a conveyor belt—is responsible for feeding the sugarcane into the equipment for impurity removal. To meet feeding requirements, this feeding ladder is usually ≥5 meters long and has a fixed, non-adjustable structure. While this type of feeding ladder can effectively transport sugarcane during operation, its excessive length does not meet road transport size restrictions, causing significant inconvenience for equipment relocation. When not in use, it also occupies a large storage space, which is a major problem for users in rural areas or villages where land resources are limited.

[0004] Existing folding feeding ladders on the market can effectively reduce size and facilitate transportation, but their folding and unfolding are mainly achieved through the control of two sets of double hydraulic cylinders, which places higher demands on the control of the hydraulic system and increases production costs. The structure is complex, and the frame is subjected to great stress when changing from folded to unfolded state, which can easily lead to structural cracking and other problems.

[0005] Therefore, there is an urgent need to design a new type of folding feeding ladder and a mobile sugarcane cleaning device to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the existing technology. One of the objectives of this utility model is to provide a new type of folding feeding ladder that reduces the control requirements of the hydraulic system, achieving the desired functionality while reducing costs.

[0007] The second objective of this utility model is to provide a new type of mobile sugarcane cleaning device that is more convenient to use.

[0008] To achieve the aforementioned objective, this utility model provides a novel folding feeding ladder, comprising a front feeding ladder and a rear feeding ladder. The front feeding ladder and the rear feeding ladder are hinged together, and the rear feeding ladder is hinged together with the machine body. A first linear drive component and a pull rod are provided between the rear feeding ladder and the machine body. The two ends of the first linear drive component are hinged together with the rear feeding ladder and the machine body, respectively. One end of the pull rod is hinged together with the machine body. Connecting rod II and connecting rod I are respectively hinged together at opposite ends of the front feeding ladder and the rear feeding ladder. Connecting rod I is hinged together with the other end of connecting rod II and the pull rod, respectively. The hinge points between connecting rod I and the rear feeding ladder, connecting rod II, and the pull rod are arranged in a triangular pattern.

[0009] As a further improvement, the bottom of the front feeding elevator, away from the machine body, is also provided with a support leg, and a support wheel is rotatably installed at the bottom of the support leg.

[0010] Furthermore, both sides of the front feeding elevator and the rear feeding elevator are detachably equipped with side baffles, and the side of the rear feeding elevator closest to the machine body is also detachably equipped with an outlet guide cover mounted above the rear feeding elevator.

[0011] Furthermore, a flip plate is provided on the back of the side baffle, and support plates are provided on the sides of the front feeding elevator and the rear feeding elevator. The flip plate is hinged to the middle of the support plate. Limiting holes are provided on the support plate along the width direction of the front feeding elevator and the rear feeding elevator. A spring pin is installed on the flip plate, and the spring pin is inserted into one of the limiting holes.

[0012] To achieve the second objective mentioned above, this utility model provides a novel mobile sugarcane impurity removal device, including the aforementioned folding feeding ladder. The machine body includes a frame assembly, a cutting device, a uniform loading ladder, and an air separator. The cutting device and the uniform loading ladder are both mounted on the frame assembly, and the folding feeding ladder, the cutting device, and the uniform loading ladder are arranged sequentially along the sugarcane conveying direction. The air separator is mounted on the uniform loading ladder. The rear feeding ladder, the tie rod, and the first linear drive component are all hinged to the frame assembly.

[0013] As a further improvement, the middle part of the material leveling and loading integrated ladder is hinged to the frame assembly, and at least two second linear drive members are provided at the end of the material leveling and loading integrated ladder away from the cutting device. The two ends of the second linear drive members are respectively hinged to the frame assembly and the material leveling and loading integrated ladder.

[0014] Furthermore, the air separation device is rotatably installed at the end of the material equalization and loading integrated ladder.

[0015] Furthermore, a rotary motor is installed on the integrated material loading ladder, and the rotary motor is connected to the air classifier through a transmission structure.

[0016] Furthermore, the air separation device is movably inserted into the material leveling and loading integrated ladder. The outer wall of the air separation device is provided with an upper limit plate, and a pressure roller is detachably installed on the upper limit plate. The material leveling and loading integrated ladder is provided with a lower limit plate, and the pressure roller is located below the lower limit plate.

[0017] Beneficial effects

[0018] Compared with the prior art, the advantages of this utility model are as follows:

[0019] 1. The folding feeding ladder of this utility model uses a pull rod instead of one of the sets of hydraulic cylinders. The pull rod cooperates with a set of first linear drive components to realize the folding and storage of the two sections of the feeding ladder. The structure is simpler, the control requirements of the hydraulic system are reduced, and the cost is reduced while achieving the function. Moreover, during the unfolding and folding process, because of the use of the pull rod solution, the end of the feeding ladder can touch the ground. The ground side shares part of the weight of the ladder itself, which reduces the force on the first linear drive components and the stress on the mounting structure at the root of the feeding ladder frame. Therefore, the overall structure is more durable.

[0020] 2. The mobile sugarcane impurity removal equipment of this utility model has an air separation device that is rotatably installed in the integrated loading ladder. In actual use, the direction of impurities being blown out can be adjusted according to the site terrain, wind direction, or loading direction, so as to avoid impurities flying around due to wind factors, making it more convenient to use.

Detailed Implementation

[0030] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0031] See Figures 1-4 This utility model discloses a novel folding feeding ladder, comprising a front feeding ladder 1 and a rear feeding ladder 2. The front feeding ladder 1 and the rear feeding ladder 2 are hinged together, and the rear feeding ladder 2 is hinged together with the machine body, forming a segmented folding feeding ladder. This is prior art and will not be described in detail here. A first linear drive component 3 and a pull rod 4 are provided between the rear feeding ladder 2 and the machine body. The first linear drive component 3 and the pull rod 4 are a set, located on both sides of the rear feeding ladder 2, making the folding feeding ladder more stable in raising and lowering. The first linear drive component 3 is an existing drive structure such as a hydraulic cylinder, a pneumatic cylinder, a screw and nut pair, or a screw jack. In this embodiment, the first linear drive component 3 is preferably a hydraulic cylinder; the pull rod 4 is a flexible cable or a rigid rod. The first linear drive component 3 has two ends hinged to the rear feed elevator 2 and the machine body, respectively. One end of the pull rod 4 is hinged to the machine body. Connecting rods II5 and I6 are hinged to opposite ends of the front feed elevator 1 and the rear feed elevator 2, respectively. One end of connecting rod II5 is hinged to the front feed elevator 1, and one end of connecting rod I6 is hinged to the rear feed elevator 2. Connecting rod I6 is hinged to the other ends of connecting rod II5 and pull rod 4, respectively. The hinge points between connecting rod I6, the rear feed elevator 2, connecting rod II5, and pull rod 4 are arranged in a triangle, so that the pull rod 4 can hold the front feed elevator 1. Preferably, a support leg 7 is provided at the bottom of the end of the front feed elevator 1 away from the machine body to support the front feed elevator 1. A support wheel 8 is rotatably installed at the bottom of the support leg 7. The support wheel 8 contacts the ground, making the front feed elevator 1 slide more smoothly and steadily when folded.

[0032] This utility model discloses a folding feeding ladder, which uses a pull rod instead of one of the hydraulic cylinders. The pull rod, in conjunction with a first linear drive unit, enables the folding and storage of the two feeding ladder sections. During folding, the first linear drive unit 3 extends, pushing the rear feeding ladder 2 upwards. Since the front feeding ladder 1 and the rear feeding ladder 2 are hinged, the rear feeding ladder 2 will lift one end of the front feeding ladder 1. During the upward movement, the angle between the front feeding ladder 1 and the rear feeding ladder 2 changes from a straight 180° to an obtuse angle, ultimately causing the two ladder sections to touch. During the folding process, the support wheels 8 initially... One section of the process involves contact with the ground, which is why the ground can help distribute its weight during unfolding. As the first linear drive 3 lifts the rear feed ladder 2 higher and higher, the support wheels 8 of the front feed ladder 1 slowly lift off the ground. The front feed ladder 1 will remain vertical due to its own weight. As the lifting reaches its limit, the front feed ladder 1 will touch the rear feed ladder 2. To achieve this process, the pull rod 4 needs to pull the connecting rod I6, and the connecting rod I6 pulls the connecting rod II to control the posture of the front feed ladder 1. At this point, the feed ladder is folded. The ladder release principle is the opposite of folding. This folding feed ladder has a simpler structure, reduces the control requirements of the hydraulic system, and achieves the desired functionality while reducing costs. Moreover, during the unfolding process, because of the pull rod solution, the end of the feed ladder can touch the ground, and the ground supports part of the ladder's weight, resulting in less stress on the first linear drive and the root mounting structure of the feed ladder frame. Therefore, the overall structure is more durable.

[0033] Preferably, side baffles 9 are detachably installed on both sides of the front feeding elevator 1 and the rear feeding elevator 2. These baffles allow the feeding elevator to better catch the material during loading by the grabber, allowing the sugarcane to slide down the wall onto the conveyor belt of the feeding elevator and preventing it from running out from the sides. An outlet guide cover 10 is also detachably installed on the side of the rear feeding elevator 2 closest to the machine body, positioned above the rear feeding elevator 2, to guide the material to the cutting device 16. To avoid interference when the folding feeding elevator is folded, both the side baffles 9 and the outlet guide cover 10 are designed to be detachable. Specifically, the back of the side baffle 9 is provided with a flip plate 11, and the sides of the front feed elevator 1 and the rear feed elevator 2 are provided with support plates 12. The flip plate 11 is hinged to the middle of the support plate 12. Specifically, the flip plate 11 and the support plate 12 can be hinged by a detachable pin. Limiting holes 13 are provided on the support plate 12 along the width direction of the front feed elevator 1 and the rear feed elevator 2. A spring pin 14 is installed on the flip plate 11. The spring pin 14 is detachably installed and is inserted into one of the limiting holes 13. When the feed elevator is folded, the spring pin 14 is pulled out, and the side baffle 9 is rotated around the middle of the support plate 12. When the spring pin 14 is aligned with the limiting hole 13 on the other side of the support plate 12, the spring pin 14 is inserted into the limiting hole 13. This operation can flip the side baffle 9 to the side of the front feed elevator 1 and the rear feed elevator 2, avoiding interference. The flip-type structure not only meets the folding requirements but also allows the side baffle 9 to remain on the feeding ladder, preventing its loss. In other embodiments, both the side baffle 9 and the outlet guide cover 10 can be fastened with bolts, enabling detachable installation.

[0034] See Figures 5-8 This utility model discloses a novel mobile sugarcane cleaning device, comprising the aforementioned folding feeding ladder. The machine body includes a frame assembly 15, a cutting device 16, a uniform loading ladder 17, and an air separator 18. These components are all structural parts of existing mobile sugarcane cleaning devices and will not be described in detail here. The cutting device 16 and the uniform loading ladder 17 are both mounted on the frame assembly 15, and the folding feeding ladder, cutting device 16, and uniform loading ladder 17 are arranged sequentially along the sugarcane conveying direction. The air separator 18 is mounted on the uniform loading ladder 17. The rear feeding ladder 2, the pull rod 4, and the first linear drive component 3 are all hinged to the frame assembly 15.

[0035] In operation, the mobile sugarcane cleaning device of this invention uses a grabber to pick up untreated whole sugarcane stalks and place them on a feeding ladder. The feeding ladder transports the sugarcane to a cutting device 16. The cutting device 16 cuts the whole sugarcane into segments while separating the sugarcane from most of the mud, sand, and sugarcane leaf impurities. The cutting device 16 then throws the sugarcane in a parabolic trajectory onto a uniform loading ladder 17. The sugarcane continues to be transported along the uniform loading ladder 17 to an air separator 18. Finally, after being cleaned again by the air separator 18, the sugarcane falls into a sugarcane-loading vehicle directly below the blower for collection. It should be noted that this operating process is the same as the operating principle of existing mobile sugarcane cleaning devices.

[0036] Preferably, the middle part of the material leveling and loading integrated ladder 17 is hinged to the frame assembly 15. At least two second linear drive members 19 are provided at the end of the material leveling and loading integrated ladder 17 away from the cutting device 16. The second linear drive members 19 are existing drive structures such as hydraulic cylinders, pneumatic cylinders, screw and nut pairs, or screw jacks. In this embodiment, the first linear drive member 3 is preferably a hydraulic cylinder. The two ends of the second linear drive member 19 are hinged to the frame assembly 15 and the material leveling and loading integrated ladder 17, respectively. The connection and support between the material leveling and loading integrated ladder 17 and the frame assembly 15 mainly rely on a rotating hinge point and double hydraulic cylinder support. When encountering bumpy roads during transportation, compared with the single-cylinder support currently on the market, the double hydraulic cylinder support significantly reduces the swaying amplitude of the equipment during transportation, greatly increasing reliability and safety. At the same time, the double hydraulic cylinder support allows the force on the material leveling and loading integrated ladder 17 and the frame assembly 15 to be distributed, no longer concentrated at one point, reducing local stress concentration and slowing down structural fatigue.

[0037] The air separator 18 in existing mobile sugarcane impurity removal equipment on the market is non-adjustable. When the working space is limited, the parking space for sugarcane loading vehicles is high, or the user requires impurities to be piled in a specific direction; or during windy weather with unpredictable wind direction, the air separator 18, due to its high installation position, can cause impurities to be blown everywhere by the wind, potentially interfering with operator operations and even entering the sugarcane loading vehicle, leading to an increase in impurity content. Therefore, in this embodiment, the air separator 18 is rotatably mounted at the end of the integrated loading ladder 17, allowing for angle adjustment. In actual use, the direction of impurity blowing can be adjusted according to the terrain, wind direction, or loading direction, avoiding the problem of impurities flying haphazardly due to wind factors, making it more convenient to use.

[0038] Preferably, a rotary motor 20 is installed on the material loading and unloading integrated ladder 17. The rotary motor 20 is connected to the air classifier 18 through a transmission structure 21, which can be a gear transmission structure, belt transmission structure, chain transmission structure, etc. By using the forward and reverse rotation of the rotary motor 20 to drive the air classifier 18 to rotate, the angle of the air classifier 18 can be adjusted, making operation more convenient and labor-saving.

[0039] Furthermore, the air classifier 18 is movably inserted into the material leveling and loading elevator 17. An upper limit plate 22 is provided on the outer wall of the air classifier 18, and a pressure roller 23 is detachably installed on the upper limit plate 22. The pressure roller 23 is mounted on a screw, which is then threadedly connected to the upper limit plate 22. A lower limit plate 24 is provided on the material leveling and loading elevator 17, and the pressure roller 23 is located below the lower limit plate 24, ensuring a certain distance between them to avoid interference. The air classifier 18 is installed using a movable insertion method, and axial positioning is achieved through the pressure roller 23 and the lower limit plate 24. This allows the air classifier 18 to rotate while preventing it from detaching from the material leveling and loading elevator 17. It also makes disassembly and assembly of the air classifier 18 more convenient during subsequent maintenance.

[0040] In other embodiments, depending on the user's expectations regarding the amount of impurities, an air classifier 18 can also be installed on the integrated loading ladder 17 corresponding to the outlet of the cutting device 16. The two air classifiers 18 work together to remove impurities, resulting in a relatively lower impurity rate in the sugarcane and cleaner impurity removal.

[0041] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
