Abstract
Description
Technical Field
[0001] This invention relates to the field of sugarcane harvesting equipment technology, and particularly to a sugarcane cutting device and sugarcane harvesting equipment. Background Technology
[0002] As an important sugar crop and economic crop, sugarcane's mechanized harvesting is crucial for reducing labor intensity and improving production efficiency. The cutting device is the core working component of a sugarcane harvester, and its performance directly determines the harvesting quality, power consumption, and subsequent processing efficiency. Currently, most mainstream sugarcane cutting devices adopt a double-blade opposing shearing structure, similar in working principle to scissors. This structure typically includes a pair of parallel or angled moving blades and a fixed blade (or both moving blades). Driven by a drive mechanism, the two blades move towards each other, cutting the sugarcane stalk through the shearing force generated by their cutting edges.
[0003] However, in practical applications, it has been found that when the blade is working, it will be slightly misaligned laterally or longitudinally due to the force of the sugarcane. The mounting components connected to the blade will continuously bear huge alternating impact loads and eccentric forces during operation. Over time, this will reduce the rigidity or fitting accuracy of the connecting components, thereby affecting the cutting effect of the sugarcane. Summary of the Invention
[0004] The main objective of this invention is to provide a sugarcane cutting device that minimizes blade misalignment caused by stress during use, thereby improving the sugarcane cutting effect.
[0005] To achieve the above objectives, the sugarcane cutting device proposed in this invention includes: Mounting rack; A fixed cutting structure includes a plurality of fixed cutters spaced apart from the mounting bracket; A movable cutting structure includes a mounting base, a driving component, and multiple movable cutters. The driving component is mounted on a mounting frame, and the mounting base is pulsatorically connected to the driving component. The multiple movable cutters are spaced apart on the mounting base. The driving component drives the mounting base to reciprocate relative to the mounting frame, so that the multiple movable cutters cooperate with multiple fixed cutters to cut sugarcane. At least one pressing roller is disposed on the mounting frame, the pressing roller abuts against the surface of the mounting base and is rotatable relative to the mounting base.
[0006] In an optional implementation, the pressing roller includes a connecting screw and a wheel body, the wheel body having through holes extending through its opposite sides, the mounting bracket having a connecting screw hole, the connecting screw passing through the through hole and screwed into the connecting screw hole.
[0007] In an alternative embodiment, the surface of the mounting base is provided with a pressing slope that extends obliquely along the upper part of the mounting frame, and the wheel abuts against the pressing slope and can roll on the pressing slope.
[0008] In an alternative implementation, the sugarcane cutting device includes a plurality of pressing rollers spaced apart along the extension direction of the mounting base.
[0009] In an optional embodiment, the drive component includes a drive motor, a crank output shaft, and a connecting shaft. The drive motor is mounted on the mounting bracket, the crank output shaft is drively connected to the output end of the drive motor, and the two opposite ends of the connecting shaft are rotatably connected to the crank output shaft and the mounting base, respectively.
[0010] In an alternative implementation, the drive unit further includes a gearbox, which is drively connected to the drive motor and the crank output shaft.
[0011] In an optional implementation, the movable cutting structure further includes a guide that connects the mounting bracket and the mounting base.
[0012] In an optional embodiment, the guide includes a guide gear and a guide rack, the mounting base has a recessed oblong hole, the guide gear is rotatably connected to the mounting bracket and accommodated in the recessed oblong hole, and the guide rack is disposed on the side wall of the recessed oblong hole and meshes with the guide gear.
[0013] The present invention also proposes a sugarcane harvesting device, including the sugarcane cutting device described above.
[0014] Compared with the prior art, the present invention has the following technical effects: The sugarcane cutting device of the present invention includes a mounting frame, a fixed cutting structure, a movable cutting structure, and a pressing roller. Multiple fixed cutters of the fixed cutting structure are spaced apart on the mounting frame. A drive component of the movable cutting structure is mounted on the mounting frame, and a mounting base is connected to the drive component. Multiple movable cutters are spaced apart on the mounting base. The drive component drives the mounting base to reciprocate relative to the mounting frame. The pressing roller is mounted on the mounting frame and abuts against the surface of the mounting base. In this application, when the drive component drives the mounting base to reciprocate, causing the multiple movable cutters and multiple fixed cutters to cooperate in cutting the sugarcane, the pressing roller continuously abuts against the surface of the mounting base and rolls on the surface of the mounting base. That is, through the pressing action of the pressing roller, misalignment between the movable cutters and the fixed cutters during cutting can be effectively avoided, thereby improving the cutting effect of the sugarcane to a certain extent.

[0021] Reference Figures 1 to 4 This invention proposes a sugarcane cutting device 300.
[0022] In this embodiment of the invention, the sugarcane cutting device 300 includes a mounting frame 310 made of metal profile, a fixed cutting structure 320, a movable cutting structure, and at least one pressing roller 340. The fixed cutting structure 320 includes a plurality of fixed cutters 321, which are also made of metal profile, fixed to the mounting frame 310 by screws, and arranged at intervals along the width direction of the mounting frame 310. The mounting frame 310 is made of metal.
[0023] The driving component 332 of the mobile cutting structure includes a drive motor 3321, a crank output shaft 3322, a connecting shaft 3323, and a reduction gearbox 3324. The drive motor 3321 is fixedly mounted to the mounting bracket 310 with screws. The reduction gearbox 3324 includes a housing and multiple meshing gears disposed inside the housing. These meshing gears effectively reduce the rotational speed of the drive motor 3321 and increase the output torque, providing power to the mobile cutter 333 for cutting the sugarcane. The structure and working principle of the reduction gearbox 3324 are existing technology and will not be described further here. The drive motor 3321 and the crank output shaft 3322 are connected to the reduction gearbox 3324, and the two ends of the connecting shaft 3323 are rotatably connected to the crank output shaft 3322 and the mounting base 331, respectively. The drive motor 3321 rotates, which in turn drives the gearbox 3324 to rotate. The gearbox 3324 drives the crank output shaft 3322 to rotate, which in turn drives the connecting shaft 3323 to drive the mounting base 331 connected to it to reciprocate relative to the mounting frame 310. This allows multiple movable cutters 333 and multiple fixed cutters 321 to cooperate with each other to cut the sugarcane.
[0024] In this application, when the driving component 332 drives the mounting base 331 to reciprocate, causing multiple movable cutters 333 and multiple fixed cutters 321 to cooperate with each other to cut the sugarcane, the pressing roller 340 continuously presses against the surface of the mounting base 331 and rolls on the surface of the mounting base 331. That is, through the pressing action of the pressing roller 340, the misalignment of the movable cutters 333 and the fixed cutters 321 during cutting can be effectively avoided, thereby improving the cutting effect of the sugarcane to a certain extent.
[0025] Please see again Figure 1 and Figure 2In this embodiment, the pressing roller 340 includes a connecting screw 341 and a wheel body 342. The wheel body 342 is made of metal and has through holes machined through its opposite sides. The diameter of the through holes is slightly larger than the diameter of the connecting screw 341. The mounting bracket 310 has connecting screw holes that are adapted to the connecting screw 341. The connecting screw 341 passes through the through holes and is screwed into the connecting screw holes, connecting the wheel body 342 to the mounting bracket 310. The pressing roller 340 of this application has a simple structure, is firmly installed, and is relatively easy to assemble and disassemble.
[0026] Please see again Figure 3 In this embodiment, the surface of the mounting base 331 is provided with a pressing slope 3311. The pressing slope 3311 is formed by machining the mounting base 331. The pressing slope 3311 is located on opposite sides of the wheel body 342 and extends obliquely along the upper part of the mounting frame 310, with an inclination angle between 1° and 3°. When cutting sugarcane, the wheel body 342 can abut against the pressing slope 3311 and roll on the pressing slope 3311. In this application, by setting the pressing slope 3311, the force exerted by the wheel body 342 against the mounting base 331 can be greater. As the sugarcane cutting action is gradually completed, the rolling of the wheel body 342 on the pressing slope 3311 gradually reaches its highest point, that is, the pressing force on the mounting base 331 gradually increases. This can further effectively prevent misalignment of the multiple moving cutters 333 and the multiple fixed cutters 321.
[0027] In this embodiment, the sugarcane cutting device 300 is equipped with two pressing rollers 340, which are respectively arranged on opposite sides of the mounting frame 310. This makes the pressure on the mounting base 331 more balanced, further preventing misalignment between the multiple moving cutters 333 and the multiple fixed cutters 321. Of course, there can also be four, six or more pressing rollers 340, which are spaced apart along the extension direction of the mounting base 331. The number of pressing rollers 340 is not specifically limited.
[0028] Please see again Figure 4In this application, the movable cutting structure also includes a guide member 334. Specifically, the guide member 334 includes a guide gear 3341 and a guide rack 3342. The mounting base 331 is machined with a recessed oblong hole 331a, which extends along the length of the mounting base 331. The guide gear 3341 is rotatably connected to the mounting frame 310 via a mounting shaft and is housed within the recessed oblong hole 331a. The guide rack 3342 can be fixed to the side wall of the recessed oblong hole 331a with screws, and the guide rack 3342 meshes with the guide gear 3341. In this application, the mounting base 331 reciprocates relative to the mounting frame 310, and the guide gear 3341 rolls along the extension direction of the guide rack 3342. Through the guiding and limiting effect of both, the mounting base 331 can be prevented from being misaligned due to force when cutting sugarcane, making the performance of the sugarcane cutting device 300 more stable.
[0029] The present invention also proposes a sugarcane harvesting device (not shown in the figure), which includes the sugarcane cutting device 300 mentioned above. The specific structure of the sugarcane cutting device 300 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.

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.
