Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to a foot brake device for a harvester. Background Technology

[0002] The foot brake of a harvester is a braking system used in agricultural machinery, primarily to ensure the stability and safety of the harvester during operation and when it is stopped. In large agricultural machinery such as harvesters, the braking system is crucial for ensuring operational safety, especially in environments with uneven ground or steep slopes. The foot brake effectively prevents the machine from slipping, reducing the risk of accidents. Traditional harvester braking systems mostly use hydraulic braking systems, relying on hydraulic oil to push the brake pads against the brake discs, thereby generating friction for braking. The advantage of this type of system is its relatively stable braking effect and suitability for complex ground environments. However, its disadvantages include relatively complex maintenance and adjustment, and the braking effect may be weakened in some extreme environments.

[0003] Patent publication number CN106612970B discloses a braking system for a combine harvester, including a main drive shaft, a braking assembly, and an outer positioning cover. The braking assembly includes multiple alternatingly combined partition plates and friction pads. The outer positioning cover is divided into a fixed part and an extension part. A material-catching notch is formed on the circumferential surface of the extension part. Material-catching protrusions are integrally connected to the partition plates, and the material-catching protrusions of multiple partition plates form a row located within the corresponding material-catching notches. The advantage of this patent lies in the fact that by simultaneously employing multiple alternatingly combined partition plates and friction pads in the braking assembly, it achieves good braking stability, improves the combine harvester's speed on flat roads and its adaptability to complex fields, and greatly enhances the combine harvester's cross-regional operation performance.

[0004] However, the current combine harvester braking system has the following problems: when the existing braking device brakes the harvester while it is in motion, the harvester itself has strong inertia, which causes the machine to tilt forward and overturn during braking. Therefore, we propose a foot brake device for harvesters. Utility Model Content

[0005] The purpose of this utility model is to provide a foot brake device for harvesters, which can solve the problem that existing braking devices in related technologies cause the harvester to tilt forward and overturn when braking, due to the strong inertia of the harvester itself.

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

[0007] A foot brake device for a harvester includes a main platform, a drive assembly on the side of the main platform, and a smooth braking device on the top of the main platform. The smooth braking device includes an outer frame, the bottom of which is fixedly connected to the top of the main platform. A pressing slide is slidably mounted through the top of the outer frame, and a brake pedal is fixedly connected to the top of the pressing slide. A friction-enhancing assembly is provided on the top of the main platform, and a brake pin plate is fixedly connected to the moving end of the friction-enhancing assembly.

[0008] The drive assembly includes multiple fixed plates, the sides of which are fixedly connected to the sides of the main body platform. A rotating shaft is rotatably mounted through the sides of each of the multiple fixed plates. A track wheel is fixedly connected to one end of each of the multiple rotating shafts, and a drive track is driven between the multiple track wheels.

[0009] The friction enhancement component includes a vertical groove plate, the bottom of which is fixedly connected to the top of the main body platform. A vertical column is fixedly connected to the inner wall of the groove of the vertical groove plate, and a horizontal plate is slidably connected to the outer wall of the vertical column. A compression spring is provided between the inner wall of the groove of the vertical groove plate and the horizontal plate. A linkage column is fixedly connected to the bottom of the horizontal plate, and the top of the brake pin plate is fixedly connected to the bottom of the linkage column. The linkage column is the moving end of the friction enhancement component.

[0010] The outer wall of the horizontal plate is in contact with the inner wall of the groove of the vertical slot plate, and a gap is provided between the brake pin plate and the rotating shaft.

[0011] A braking buffer device is provided on the outer wall of the horizontal plate. The braking buffer device includes a baffle. The side of the baffle is fixedly connected to the outer wall of the horizontal plate. A through groove is opened on the side of the baffle. A strong elastic telescopic rod is fixedly connected to the side of the vertical groove plate. An impact pad is fixedly connected to the telescopic end of the strong elastic telescopic rod. A buffer slide is slidably installed through the side of the outer frame. A protective buffer frame is fixedly connected to the side of the buffer slide away from the baffle.

[0012] The inner diameter of the groove is equal to the outer diameter of the buffer slide, and the impact pad is located on the movement trajectory of the buffer slide.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model, through the setting of a smooth braking device, enables the outer frame, sliding column, brake pedal, vertical groove plate, vertical column, horizontal plate, compression spring, linkage column, and brake pin plate to cooperate. The linkage column slides downward, causing the brake pin plate to slide downward, and the brake pin plate slides downward to contact the ground. Due to the strong friction characteristics of the brake pin plate, the device can be effectively and smoothly braked while in motion, avoiding the forward tilting and overturning of the machine body during braking due to the strong inertia of the harvester itself.

[0015] This utility model, through the setting of a braking buffer device, enables the baffle, through groove, strong elastic telescopic rod, impact pad, buffer slide, and protective buffer frame to cooperate. When an external force impacts the protective buffer frame, the protective buffer frame causes the buffer slide to slide through the through groove toward the impact pad. This allows the strong elastic telescopic rod to disperse and absorb the impact force after being impacted, ensuring that in an emergency, the buffer assembly can disperse and absorb the external impact force to ensure the safety of the driver.

[0023] 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.

[0024] like Figure 1-5As shown, a foot brake device for a harvester includes a main platform 1. A drive assembly is provided on the side of the main platform 1, and a smooth braking device 6 is provided on the top of the main platform 1. The smooth braking device 6 includes an outer frame 61. The bottom of the outer frame 61 is fixedly connected to the top of the main platform 1, and a pressing slide 62 is slidably installed through the top of the outer frame 61. A brake pedal 63 is fixedly connected to the top of the pressing slide 62. A friction enhancement assembly is provided on the top of the main platform 1, and a brake nail plate 69 is fixedly connected to the moving end of the friction enhancement assembly. The ground surface of the brake nail plate 69 is set with an extremely rough surface, which will apply extremely strong friction to the ground after contacting the ground.

[0025] The drive assembly includes multiple fixed plates 2, the sides of which are fixedly connected to the sides of the main body platform 1. A rotating shaft 3 is rotatably mounted through the sides of the multiple fixed plates 2. A track wheel 4 is fixedly connected to one end of the multiple rotating shafts 3. A drive track 5 is connected between the multiple track wheels 4. This is the existing structure and will not be supplemented further.

[0026] The friction enhancement component includes a vertical slot plate 64, the bottom of which is fixedly connected to the top of the main body platform 1. A vertical column 65 is fixedly connected to the inner wall of the slot of the vertical slot plate 64, and a horizontal plate 66 is slidably connected to the outer wall of the vertical column 65. A compression spring 67 is provided between the inner wall of the slot of the vertical slot plate 64 and the horizontal plate 66. A linkage column 68 is fixedly connected to the bottom of the horizontal plate 66, and the top of the brake pin plate 69 is fixedly connected to the bottom of the linkage column 68. The linkage column 68 is the moving end of the friction enhancement component, and the setting of the moving end ensures the continuous operation of the device.

[0027] The outer wall of the horizontal plate 66 is in contact with the inner wall of the groove of the vertical slot plate 64, and a gap is provided between the brake pin plate 69 and the rotating shaft 3. The necessary gap ensures that the device will not interfere with movement during operation.

[0028] According to the above structure, in an emergency, the operator presses the brake pedal 63, causing the brake pedal 63 to slide downward. The downward sliding of the brake pedal 63 causes the sliding column 62 to slide downward. The downward sliding of the sliding column 62 causes the horizontal plate 66 to slide downward under the restriction of the vertical column 65. The downward sliding of the horizontal plate 66 causes the linkage column 68 to slide downward. The downward sliding of the linkage column 68 causes the brake pin plate 69 to slide downward. The downward sliding of the brake pin plate 69 brings it into contact with the ground. Due to the strong frictional characteristics of the brake pin plate 69, the traveling device can be effectively and smoothly braked, avoiding the machine body from tilting forward and overturning during braking due to the strong inertia of the harvester itself.

[0029] like Figure 1-5As shown, a braking buffer device 7 is provided on the outer wall of the horizontal plate 66. The braking buffer device 7 includes a baffle 71. The side of the baffle 71 is fixedly connected to the outer wall of the horizontal plate 66. A through groove 72 is opened on the side of the baffle 71. A strong elastic telescopic rod 73 is fixedly connected to the side of the vertical groove plate 64. An impact pad plate 74 is fixedly connected to the telescopic end of the strong elastic telescopic rod 73. A buffer slide column 75 is slidably installed through the side of the outer frame 61. A protective buffer frame 76 is fixedly connected to the side of the buffer slide column 75 away from the baffle 71. The protective buffer frame 76 can effectively protect the entire device.

[0030] The inner diameter of the slot 72 is equal to the outer diameter of the buffer slide 75, and the impact pad 74 is located on the movement trajectory of the buffer slide 75, so that the buffer assembly can provide additional protection when no emergency braking occurs.

[0031] According to the above structure, when the horizontal plate 66 slides down, it causes the baffle 71 to move downward, so that the through groove 72 is aligned with the impact pad 74. When the device is impacted, the external force hits the protective buffer frame 76, causing the protective buffer frame 76 to drive the buffer slide column 75 to slide through the through groove 72 toward the impact pad 74. This allows the elastic telescopic rod 73 to disperse and absorb the impact force after being impacted, ensuring that in an emergency, the buffer assembly can disperse and absorb the external impact force to ensure the safety of the driver.

[0032] 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.
