Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a cutting box of a sugarcane harvester. Background Art

[0002] Sugarcane harvesting is a key obstacle hindering the full mechanization of sugarcane production. Currently, sugarcane harvesting relies primarily on primitive manual felling methods, resulting in outdated harvesting methods. The cutter box, a key component of sugarcane harvesters, is responsible for cutting the harvested sugarcane into sections. However, most harvesters on the market only harvest whole stalks and lack a cutter function, resulting in low sugarcane harvesting efficiency. Utility Model Content

[0003] In view of the above defects or shortcomings, the purpose of the present invention is to provide a sugarcane harvester cutting box with a simple and reliable structure.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0005] A sugarcane harvester cutting box includes a box body, in which two sets of synchronously meshing power output mechanisms are installed, wherein the power output mechanisms include: first and second power output structures with identical structures, the output ends of the first and second power output structures are meshed, and the output end of the second power output structure is connected to an inertia wheel mechanism.

[0006] The first power output structure includes: a first output shaft, a first connecting disk is installed on the first output shaft, and a first synchronous gear is installed on the first connecting disk; the second power output structure includes: a second output shaft, a second connecting disk is installed on the second output shaft, and a second synchronous gear is installed on the second connecting disk, and the second synchronous gear is meshed with the first synchronous gear.

[0008] The inertia wheel mechanism includes: an inertia shaft mounted on a housing, a gear of the inertia shaft meshing with the second synchronous gear, a friction disk mounted on an output end of the inertia shaft, and an inertia wheel connected to the friction disk.

[0009] The friction disc is spline-connected to the inertia shaft.

[0010] The inertia shaft is supported by spherical roller bearings and cylindrical roller bearings.

[0011] A friction plate is provided on the horizontal contact surface between the inertia wheel and the friction disc.

[0012] A self-lubricating bearing is installed between the inertia wheel and the friction disk.

[0013] An oil seal is provided at the bottom end of the bearing hole of the box body.

[0014] The box body is provided with a box cover.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model provides a cutting box for a sugarcane harvester. By arranging dual power input and output, the power of the cutting box comes from two hydraulic motors. At the same time, the two output shafts need to have a synchronous structure, and it can also ensure that the cutters on the two cutter discs do not interfere with each other, thereby greatly improving the efficiency of the harvesting work. In addition, the number of bearings in the cutting box structure of the sugarcane harvester of the utility model is small, so that the weight of the whole machine is light and the cost is reduced.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0020] like Figure 1 As shown, the utility model provides a sugarcane harvester cutting box, including a box body 9, a box cover 10 is provided on the box body 9, two sets of synchronously meshed power output mechanisms are installed in the box body 9, two cutting discs are installed on the two sets of power output mechanisms, and the output end of the power output mechanism is connected to the inertia wheel mechanism;

[0021] Specifically, the power output mechanism includes: first and second power output structures with identical structures, the output ends of the first and second power output structures are meshed, and the output end of the second power output structure is connected to an inertia wheel mechanism; the first and second power output structures are respectively connected to hydraulic motors to provide power.

[0022] Among them, the first power output structure includes: a first output shaft 1, a first connecting disk 2 is installed on the first output shaft 1, and a first synchronous gear 3 is installed on the first connecting disk 2; the second power output structure includes: a second output shaft 12, a second connecting disk 13 is installed on the second output shaft 12, a second synchronous gear 14 is installed on the second connecting disk 13, and the second synchronous gear 14 is engaged with the first synchronous gear 3; preferably, the first and second output shafts 1 and 12 are both installed on the box body 9 through spherical roller bearings and bearing sleeves 4, and an oil seal 15 is provided at the bottom end of the bearing hole of the box body 9.

[0023] The inertia wheel mechanism includes an inertia shaft 8 , a gear of the inertia shaft 8 meshing with the second synchronous gear 14 , a friction disc 7 mounted on the output end of the inertia shaft 8 , and the friction disc 7 connected to the inertia wheel 5 .

[0024] Preferably, the friction disc 7 is spline-connected to the inertia shaft 8, and the gear of the inertia shaft 8 is meshed with the single synchronous gear. Exemplarily, the gear of the inertia shaft 8 is meshed with the second synchronous gear 14. By setting the phase of the output shaft and the output gear, the gear of the inertia shaft 8 can drive the synchronous gear of the cutting box with the power from the two hydraulic motors on the opposite sides of the harvester, and can also ensure that the cutters on the two cutting discs do not interfere with each other, thereby greatly improving the efficiency of the harvesting work. In addition, the cutting box structure of the sugarcane harvester of the present invention has a small number of bearings and a light weight of the entire machine. There is a friction plate between the friction disc and the inertia wheel, which can slide relative to each other in the event of overload to protect the internal gears.

[0025] Exemplarily, the inertia wheel 5 and the pressure plate are connected via a butterfly spring and a screw. A friction plate 6 is disposed between the inertia wheel 5 and the friction plate 7. Exemplarily, two friction plates 6 are optimally disposed between the inertia wheel 5 and the friction plate 7. Furthermore, a self-lubricating bearing 11 is disposed between the input inertia wheel 5 and the friction plate 7.

[0026] The working process and principle of this utility model are as follows:

[0027] When the gearbox is operating, the two hydraulic motors simultaneously input power to the first and second output shafts 1 and 12. The gear on the inertia shaft 8 meshes with one of the output gears, and the two synchronous gears mesh with each other, causing the cutter rollers attached to the two output shafts to mesh synchronously. The blades on the cutter rollers cut the sugarcane. A speed ratio exists between the synchronous gears and the gears on the inertia shafts, causing the inertia shaft, along with the inertia wheel, to rotate together at a faster speed than the output shafts. If the blade resistance is too great and the hydraulic motor torque is insufficient, the inertia wheel uses its own inertia to drive the synchronous gears to continue rotating in the original direction. If the resistance exceeds the limit, the friction plate inside the inertia wheel slips, dissipating the peak torque and protecting the gears and bearings from damage.

[0028] For those skilled in the art, it is obvious that the above-mentioned specific examples are only preferred embodiments of the present invention. Therefore, any improvements and changes that may be made by those skilled in the art to certain parts of the present invention still reflect the principles of the present invention and still achieve the purpose of the present invention, and all fall within the scope of protection of the present invention.
