Description

Technical Field

[0001] This invention relates to the field of sugarcane harvesting technology, and in particular to a sugarcane leaf-removing device and sugarcane harvesting equipment. Background Technology

[0002] As a globally important sugar and energy crop, sugarcane's mechanized harvesting is crucial for reducing labor intensity and improving production efficiency. During the sugarcane harvesting process, the surface of the harvested sugarcane stalks is covered with tough leaf sheaths and impurities, which must be effectively stripped to meet the quality requirements of subsequent pressing or processing. Therefore, the leaf stripping device is one of the core functional modules of sugarcane combine harvesters or independent leaf stripping equipment.

[0003] Currently, common mechanized sugarcane peeling devices mainly adopt rotating brush roller type, counter-rolling extrusion type, or combined structure. Their basic principle is that multiple rotating peeling elements (such as brush rollers, rubber strips, metal spring teeth, etc.) generate friction, scraping, or impact with the surface of the sugarcane stalk, thereby peeling off the leaf sheath. The structure of the above devices is not only relatively complex, but also easily damages the surface of the sugarcane peel under friction and impact. Summary of the Invention

[0004] The main objective of this invention is to provide a sugarcane leaf-peeling device that simplifies its mechanical structure while reducing damage to the sugarcane during the leaf-peeling process.

[0005] To achieve the above objectives, the sugarcane leaf-removing device proposed in this invention includes: Mounting rack; The drive mechanism includes a limiting roller, a conveying roller, and a leaf-stripping drive component mounted on the mounting frame. The limiting roller and the conveying roller are arranged vertically at intervals, and the leaf-stripping drive component is drively connected to the conveying roller. The leaf stripping structure includes a lower leaf stripping fork and an upper leaf stripping fork mounted on the mounting frame. The lower leaf stripping fork and the upper leaf stripping fork are spaced apart and located upstream of the conveying roller, and are provided with a lower leaf stripping groove and an upper leaf stripping groove. The conveyor roller drives the sugarcane to move within the lower and upper leaf stripping grooves, so that the lower and upper leaf stripping forks separate the sugarcane leaves from the sugarcane.

[0006] In an optional embodiment, the lower leaf-stripping fork includes a lower frame, a lower mounting rod, a plurality of limiting screws, and a lower spring. The lower frame is connected to the lower mounting rod and forms the lower leaf-stripping groove. The lower mounting rod has a mounting waist-shaped hole, and the mounting frame has a plurality of mounting holes. One of the limiting screws passes through the mounting waist-shaped hole and one of the mounting holes to limit the lower mounting rod to the mounting frame. The lower spring is elastically connected to the lower mounting rod and the mounting frame.

[0007] In an optional embodiment, the groove opening on the side of the lower leaf stripping groove opposite to the conveying roller is provided with a leaf stripping blade.

[0008] In an optional embodiment, the limiting roller includes a first roller body, a base body, a connecting rod, and a limiting spring. The mounting frame has a sliding limiting groove that extends along the height direction of the mounting frame. The opposite sides of the base body are slidably embedded in the sliding limiting groove. The first roller body is rotatably connected to the base body and located above the conveying roller. The connecting rod is connected to the base body. The limiting spring is sleeved on the connecting rod and elastically abuts against the mounting frame and the base body.

[0009] In an optional embodiment, the mounting bracket is provided with an adjusting stud and a pressure plate. The pressure plate has a clearance hole and a through hole. The limiting roller also includes an adjusting nut. The adjusting stud passes through the clearance hole, and the connecting rod part passes through the through hole. The limiting spring elastically abuts against the pressure plate. The adjusting nut is screwed onto the adjusting stud and abuts against the side of the pressure plate away from the limiting spring.

[0010] In an optional embodiment, the conveying roller includes a second roller body and a plurality of conveying plates. The second roller body is rotatably connected to the mounting frame and is drively connected to the leaf stripping drive. The plurality of conveying plates are arranged at circumferential intervals along the second roller body.

[0011] In an optional embodiment, the leaf stripping drive includes a drive motor and a gearbox mounted on the mounting frame, the drive motor being drivenly connected to the gearbox, and the gearbox being drivenly connected to the second roller body.

[0012] In an optional embodiment, the sugarcane peeling device further includes a cutting drive and a cutting saw, the cutting drive being mounted on the mounting frame, and the cutting saw being rotatably connected to the mounting frame and drivingly connected to the cutting drive.

[0013] In an optional embodiment, the sugarcane peeling device further includes a protective cover, which is mounted on the mounting frame and has a protective cavity and a cutting groove communicating with the protective cavity. The cutting saw is housed within the protective cavity and is partially exposed by the cutting groove.

[0014] The present invention also proposes a sugarcane harvesting device, including the sugarcane leaf stripping device described above.

[0015] The sugarcane leaf-peeling device of the present invention includes a mounting frame, a limiting roller and a conveying roller of the driving mechanism, and a leaf-peeling driving component mounted on the mounting frame. The limiting roller and the conveying roller are arranged vertically at intervals. The leaf-peeling driving component is drivenly connected to the conveying roller. The lower leaf-peeling fork and the upper leaf-peeling fork of the leaf-peeling structure are arranged at intervals upstream of the conveying roller and are provided with a lower leaf-peeling groove and an upper leaf-peeling groove. The working principle of the sugarcane leaf-peeling device of this application is as follows: one end of the sugarcane to be peeled is inserted between the lower leaf-peeling groove and the upper leaf-peeling groove, which are arranged vertically at intervals. The leaf-peeling driving component drives the conveying roller to rotate, thereby causing the sugarcane to move in the lower leaf-peeling groove and the upper leaf-peeling groove. Since the leaf sheath part attached to the surface of the sugarcane protrudes, when the lower leaf-peeling groove and the upper leaf-peeling groove move, the leaf sheath abuts against the groove opening of the lower leaf-peeling groove and the upper leaf-peeling groove. Under the continuous conveying of the conveying roller, the leaf sheath is peeled off from the sugarcane by the lower leaf-peeling fork and the upper leaf-peeling fork. As can be seen from the above, this application can separate sugarcane leaves from sugarcane using only two lower and upper leaf-stripping forks spaced apart vertically. Its structure is relatively simple. At the same time, the use of scraping to separate sugarcane leaves from sugarcane can greatly reduce the damage to the surface of sugarcane caused by rotational impact. Attached Figure Description

[0022] Reference Figures 1 to 5 This invention proposes a sugarcane leaf-peeling device 400.

[0023] In this embodiment of the invention, the sugarcane peeling device 400 includes a mounting frame 410 formed by splicing metal profiles and a drive mechanism 420 for conveying sugarcane 500. The drive mechanism 420 includes a limiting roller 421, a conveying roller 422, and a peeling drive component 423 mounted on the mounting frame 410. The limiting roller 421 and the conveying roller 422 are arranged vertically at intervals. Specifically, the limiting roller 421 includes a first roller body 4211, a seat body 4212, a connecting rod 4213, and a limiting spring 4214. The seat body 4212 is U-shaped. The mounting frame 410 is machined with openings. A sliding limiting groove 410b is provided, which extends along the height direction of the mounting frame 410. The opposite sides of the seat 4212 are slidably embedded in the sliding limiting groove 410b. The first roller 4211 is rotatably connected to the seat 4212 via a connecting protrusion at its end, and is positioned above the conveyor roller 422. A connecting rod 4213 is connected to the side of the seat 4212 away from the first roller 4211. A limiting spring 4214 is sleeved on the connecting rod 4213 and elastically abuts against the mounting frame 410 and the seat 4212. Under the elastic force of the limiting spring 4214, the seat 4212 and the first roller 4211 tend to move towards the second roller 4221, i.e., the lower part of the mounting frame 410.

[0024] It should be noted that in this application, the surface of the first roller 4211 extends in an arc shape, and the gap between the first roller 4211 and the conveyor roller 422 should be slightly smaller than the diameter of the mature sugarcane 500, so that the first roller 4211 and the conveyor roller 422 can clamp and convey the sugarcane 500. Furthermore, when the sugarcane 500 is inserted between the first roller 4211 and the conveyor roller 422, under its force, the seat 4212 resists the elastic force of the limiting spring 4214 and moves upward, increasing the gap between it and the conveyor roller 422 to accommodate sugarcane 500 with different diameters. Thus, the structure of the limiting roller 421 is not only relatively simple and can effectively press the sugarcane 500 onto the surface of the conveyor roller 422, achieving stable conveying, but the limiting roller 421 can also adapt to sugarcane 500 with different diameters, making the drive mechanism 420 more practical.

[0025] Please see again Figure 3In this embodiment, the mounting bracket 410 is provided with an adjusting stud 411 and a pressure plate 412. The pressure plate 412 is machined to have a clearance hole (not shown) and a through hole (not shown). The limiting roller 421 also includes an adjusting nut 4215. The adjusting stud 411 passes through the clearance hole, the connecting rod 4213 partially passes through the through hole, the limiting spring 4214 elastically abuts against the pressure plate 412, and the adjusting nut 4215 is screwed onto the adjusting stud 411 and abuts against the side of the pressure plate 412 away from the limiting spring 4214. In practical use, by rotating the adjusting nut 4215, the pressure plate 412 can move along the vertical direction of the mounting frame 410 under the elastic force of the limiting spring 4214 and the pressure of the adjusting nut 4215. Then, by adjusting the compression of the limiting spring 4214, the magnitude of the force of the first roller 4211 against the surface of the sugarcane 500 can be adjusted, so that the conveying of the sugarcane 500 is more stable and smooth.

[0026] The conveyor roller 422 includes a second roller 4221 disposed below the first roller 4211 and multiple conveyor plates 4222. The second roller 4221 is rotatably connected to the mounting frame 410 via bearings. One end of the second roller 4221 is driven by a leaf-stripping drive component 423. The leaf-stripping drive component 423 includes a drive motor 4231 mounted on the mounting frame 410 and a reduction gearbox 4232. The reduction gearbox 4232 consists of a housing and multiple meshing gears disposed therein. The reduction gearbox 4232 is used to reduce the output speed of the drive motor 4231 while increasing the output torque. The working structure and principle of the reduction gearbox 4232 are relatively mature existing technologies and will not be described in detail here. The output shaft of the drive motor 4231 is driven by the reduction gearbox 4232, and the reduction gearbox 4232 is driven by the second roller 4221. The second roller 4221 drives the multiple conveyor plates 4222. In practical applications, multiple conveyor plates 4222 cyclically abut against the surface of the sugarcane 500. Through stress concentration, the sugarcane 500 can be prevented from slipping and getting stuck during the conveying process, and the drive mechanism 420 conveys the sugarcane 500 more smoothly.

[0027] The lower leaf-stripping fork 431 and upper leaf-stripping fork 432 of the leaf-stripping structure 430 are made of sheet metal and are spaced apart upstream of the conveyor roller 422. "Upstream" means along the conveying direction of the sugarcane 500. The lower leaf-stripping fork 431 and upper leaf-stripping fork 432 are located at the front end of the conveyor roller 422 and the limiting roller 421. The lower leaf-stripping fork 431 and upper leaf-stripping fork 432 are formed into the lower leaf-stripping groove 4311a and the upper leaf-stripping groove 432a through bending, stamping and other processes.

[0028] The working principle of the sugarcane leaf-peeling device 400 of this application is as follows: one end of the sugarcane 500 to be peeled is inserted between the limiting roller 421 and the conveying roller 422, which are spaced apart vertically, through the lower leaf-peeling groove 4311a and the upper leaf-peeling groove 432a. The leaf-peeling drive member 423 drives the conveying roller 422 to rotate, thereby causing the sugarcane 500 to move within the lower leaf-peeling groove 4311a and the upper leaf-peeling groove 432a. Since the leaf sheath part attached to the surface of the sugarcane 500 protrudes, when the lower leaf-peeling groove 4311a and the upper leaf-peeling groove 432a move, the leaf sheath abuts against the groove opening of the lower leaf-peeling groove 4311a and the upper leaf-peeling groove 432a. Under the continuous conveying of the conveying roller 422, the leaf sheath is peeled off from the sugarcane 500 by the lower leaf-peeling fork 431 and the upper leaf-peeling fork 432. As can be seen from the above, this application can separate the sugarcane leaves from the sugarcane 500 by using only two lower leaf-peeling forks 431 and upper leaf-peeling forks 432 arranged at intervals. Its structure is relatively simple. At the same time, the scraping method is used to separate the sugarcane leaves from the sugarcane 500, which can greatly reduce the damage caused by rotational impact to the surface of the sugarcane 500.

[0029] Please see again Figure 1 and Figure 2 In this embodiment, the lower leaf-stripping fork frame 431 includes a lower frame body 4311, a lower mounting rod 4312, multiple limiting screws, and a lower spring 4313. The lower frame body 4311 extends in an upward-opening "U" shape, forming a lower leaf-stripping groove 4311a. The width of the lower leaf-stripping groove 4311a is slightly larger than the diameter of the sugarcane 500. The lower mounting rod 4312 is connected to the lower end of the lower frame body 4311 and has two oblong mounting holes 4312a machined into it. The mounting frame 410 has four mounting holes 410a. Two mounting holes 410a are located within a mounting waist-shaped hole 4312a, and the distance between the two mounting holes 410a is less than the extension length of the mounting waist-shaped hole 4312a. A thread is provided within the mounting hole 410a, and a limiting screw passes through the mounting waist-shaped hole 4312a and the mounting hole 410a, limiting the lower mounting rod 4312 within the mounting frame 410. A lower spring 4313 elastically connects the lower mounting rod 4312 and the mounting frame 410. The elastic force of the lower spring 4313 causes the lower frame 4311 to have an upward pushing tendency. After the sugarcane 500 is placed in the lower leaf-peeling groove 4311a, under the action of its own weight and the elastic force of the lower spring 4313, the sugarcane 500 can fit more tightly against the groove wall of the lower leaf-peeling groove 4311a, thereby allowing the lower frame 4311 to better peel the sugarcane leaves from the sugarcane 500.

[0030] The structure of the upper leaf stripping fork 432 is the same as that of the lower leaf stripping fork 431. The difference is that the upper leaf stripping groove 432a of the upper leaf stripping fork 432 faces the lower part of the mounting frame 410, that is, the upper frame (not shown) extends in a downward "U" shape, and the elastic force of the upper spring makes the upper frame tend to push downward.

[0031] Furthermore, in this embodiment, the groove opening of the lower leaf stripping groove 4311a on the side opposite to the conveyor roller 422 is provided with a conical leaf stripping blade 4314 by mechanical processing. By providing the leaf stripping blade 4314, the stripping of sugarcane leaves can be made smoother.

[0032] Please see again Figure 1 and Figure 3 In this embodiment, the sugarcane leaf peeling device 400 also includes a cutting drive component 440 and a cutting saw 450. The cutting drive component 440 includes a cutting drive motor and a belt pulley transmission structure mounted on the mounting frame 410. The cutting saw 450 is rotatably connected to the mounting frame 410 and is connected to the cutting drive motor via the belt pulley transmission structure. Driven by the cutting drive motor, the cutting saw 450 rotates to cut and trim the sugarcane leaves at the end of the sugarcane 500 as a whole.

[0033] Furthermore, the sugarcane peeling device 400 also includes a protective cover 460, which is mounted on the mounting frame 410 and forms a protective cavity and a cutting groove 460a communicating with the protective cavity. The cutting saw 450 is housed in the protective cavity and is partially exposed through the cutting groove 460a. By setting up this protective cover 460, the cutting saw 450 can be prevented from damaging the surrounding sugarcane 500 or causing safety hazards during use. In actual use, the worker first places the cut end of the sugarcane 500 into the cutting groove 460a, and then uses the cutting saw 450 to cut and trim the sugarcane leaves at the end of the sugarcane 500. Then, the sugarcane 500 is inserted from the lower peeling groove 4311a and the upper peeling groove 432a between the conveying roller 422 and the limiting roller 421 for side peeling, thus achieving a better peeling effect.

[0034] The present invention also proposes a sugarcane harvesting device (not shown in the figure), which includes a sugarcane leaf stripping device 400. The specific structure of the sugarcane leaf stripping device 400 is as described in the above embodiments. Since the sugarcane harvesting device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0035] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
