Description

Technical Field

[0001] This utility model belongs to the field of sugarcane harvester technology, specifically relating to a reinforced rear drive axle assembly for a sugarcane harvester. Background Technology

[0002] In sugarcane harvesting operations, sugarcane harvesters need to continuously move in the field and complete operations such as sugarcane cutting and conveying. The rear drive axle assembly, as the core component for transmitting power, controlling the direction of travel and realizing braking, directly determines the harvester's operating efficiency and safety performance through its operational stability.

[0003] While current mainstream sugarcane harvester rear drive axle assemblies can meet basic power transmission and braking requirements, during the cutting and conveying process, the sugarcane sap contained in the stalks (mainly composed of sucrose, water, and a small amount of impurities) is easily splashed due to mechanical compression and vibration, and a large amount adheres to the surface of the rear drive axle brake discs. The sugarcane sap adhering to the brake discs will quickly evaporate and concentrate, forming a sticky sucrose residue layer.

[0004] This residual layer can cause instability in the friction coefficient between the brake disc and the brake caliper, resulting in mild braking lag and abnormal brake noise, or even severe braking performance degradation, increasing the safety risks of the harvester when turning and avoiding obstacles in the field. Utility Model Content

[0005] The purpose of this invention is to provide a reinforced rear drive axle assembly for a sugarcane harvester, which can clean the sugarcane sap adhering to the brake disc, reduce the amount of sugarcane sap adhering to the brake disc, and thus reduce the impact of sugarcane sap on the brake disc.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A reinforced rear drive axle assembly for a sugarcane harvester includes a gearbox and a tube beam fixedly connected to the rear side of the gearbox. A drive shaft is mounted on the gearbox, a brake disc is fixedly connected to the outer side of the drive shaft, and a brake caliper adapted to the brake disc is fixedly connected to the tube beam.

[0008] It also includes a cleaning fluid storage tank, on which a delivery pump is installed. The delivery pump is connected to a liquid outlet via a delivery pipe. The liquid outlet is fixedly connected to the pipe beam and is installed on the outside of the brake disc.

[0009] Furthermore, the rear drive axle assembly also includes a friction cleaning structure mounted on the liquid outlet head for friction cleaning of the sugarcane sap on the brake disc.

[0010] Furthermore, the friction cleaning structure includes two connecting plates fixedly connected to the liquid outlet head. The two connecting plates are located on both sides of the brake disc. A telescopic actuating component is fixedly connected to each of the two connecting plates. A friction cleaning component is fixedly connected to one end of the telescopic actuating component near the brake disc.

[0011] Furthermore, a sleeve body is installed on the connecting plate, and a shaft body is slidably connected inside the sleeve body. One end of the shaft body is fixedly connected to the friction cleaning component. An electromagnet adapted to the shaft body is fixedly connected to the connecting plate, and a return spring is installed inside the sleeve body.

[0012] Furthermore, the sleeve body is rotatably connected to the connecting plate, a second meshing gear is fixedly connected to the outer side of the sleeve body, and a first meshing gear is fixedly connected to the outer side of the transmission shaft. The first meshing gear and the second meshing gear are meshed together.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figures 1-4 As shown, a reinforced rear drive axle assembly for a sugarcane harvester includes a gearbox 1 and a tube beam 2 fixedly connected to the rear side of the gearbox 1. A drive shaft 3 is mounted on the gearbox 1, and a brake disc 4 is fixedly connected to the outer side of the drive shaft 3. A brake caliper 5 adapted to the brake disc 4 is fixedly connected to the tube beam 2, and the brake disc 4 can be braked by the brake caliper 5.

[0024] The core of this technical solution is that it also includes a cleaning solution storage tank, on which a delivery pump is installed. The cleaning solution storage tank and the delivery pump can be installed on a sugarcane harvester. The delivery pump is connected to a liquid outlet 7 through a delivery pipe 6. The liquid outlet 7 is fixedly connected to the pipe beam 2 and is installed on the outside of the brake disc 4. When the delivery pump is turned on, the cleaning solution inside the cleaning solution storage tank can be delivered into the liquid outlet 7. The liquid outlet 7 sprays the solution onto the brake disc 4, which can clean the sugarcane juice adhering to the brake disc 4, reduce the sugarcane juice adhering to the brake disc 4, and thus reduce the impact of the sugarcane juice on the brake disc 4.

[0025] Specifically, the liquid outlet head 7 has a U-shaped structure, that is, a rectangular cavity is opened on the liquid outlet head 7, and several liquid outlet holes are opened on the inner walls of both sides of the rectangular cavity. The edge of the brake disc 4 is located inside the rectangular cavity, so that the cleaning fluid can be discharged in the area that matches the brake disc 4 on both sides and the brake caliper 5.

[0026] like Figures 1-4 As shown, in some embodiments, the rear drive axle assembly also includes a friction cleaning structure mounted on the liquid outlet 7 for friction cleaning of the sugarcane sap on the brake disc 4.

[0027] Specifically, the friction cleaning structure includes two connecting plates 8 fixedly connected to the liquid outlet head 7. The two connecting plates 8 are located on both sides of the brake disc 4. Telescopic actuators are fixedly connected to both connecting plates 8. A friction cleaning component 9 is fixedly connected to one end of the telescopic actuator near the brake disc 4. When the telescopic actuator is activated, it can drive the friction cleaning component 9 to move, adjust the distance between the friction cleaning component 9 and the brake disc 4, and control the friction force between the friction cleaning component 9 and the brake disc 4.

[0028] In some embodiments, the friction cleaning component 9 may include a mounting plate connected to the telescopic action component, on which a cleaning cotton is fixedly connected.

[0029] The friction cleaning component 9 can also be used to clean brushes or other structures with friction cleaning properties.

[0030] The telescopic mechanism can be hydraulic or electric, such as... Figures 2-4 As shown, in some embodiments, a sleeve body 12 is installed on the connecting plate 8, and a shaft body 11 is slidably connected inside the sleeve body 12. One end of the shaft body 11 is fixedly connected to the friction cleaning component 9. An electromagnet 14 adapted to the shaft body 11 is fixedly connected on the connecting plate 8. By activating the electromagnet 14, a magnetic pulling force can be applied to the shaft body 11, pulling the friction cleaning component 9 and the brake disc 4 apart. A return spring 15 is installed inside the sleeve body 12. When the electromagnet 14 is de-energized, a pushing force can be applied to the shaft body 11 through the return spring 15, so that the friction cleaning component 9 and the brake disc 4 abut against each other.

[0031] like Figure 1 and Figures 3-4 As shown, the sleeve body 12 is rotatably connected to the connecting plate 8. A second meshing gear 13 is fixedly connected to the outer side of the sleeve body 12, and a first meshing gear 10 is fixedly connected to the outer side of the transmission shaft 3. The first meshing gear 10 and the second meshing gear 13 are meshed together. By rotating the transmission shaft 3, the first meshing gear 10 can drive the second meshing gear 13 to rotate, inputting rotational kinetic energy to the friction cleaning component 9, thereby driving the friction cleaning component 9 to better clean the brake disc 4.

[0032] In some embodiments, the sleeve body 12 can also be driven to rotate by other rotary drive devices, such as a servo motor fixedly connected to the connecting plate 8, which can drive the sleeve body 12 to rotate.

[0033] Meanwhile, a turntable body 16 is rotatably connected to one end of the shaft body 11 near the return spring 15. One end of the return spring 15 abuts against the turntable body 16. During the process of the sleeve body 12 driving the shaft body 11 to rotate, the friction between the shaft body 11 and the return spring 15 can be reduced through the turntable body 16.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
