Description

Technical Field

[0001] This application relates to the field of tracked harvester technology, and in particular to a tracked harvester chassis and a tracked harvester. Background Technology

[0002] Currently, tracked harvesters generally use a fixed mounting system for their track rollers. This design causes uneven ground to be directly transmitted to the machine body, resulting in a poor driving experience for the operator. Furthermore, when a tracked harvester crosses a field ridge, the fixed wheel structure causes the front of the machine to lift. Once the harvester's center of gravity crosses the ridge, the front end drops sharply and impacts the ground, generating a significant force. This not only severely affects the operator's experience but also shortens the lifespan of machine components. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a tracked harvester chassis and a tracked harvester to solve the problem that the existing tracked harvester's support roller assembly method is greatly affected by road surface undulations.

[0004] According to a first aspect of the present invention, a tracked harvester chassis is provided, wherein the tracked harvester chassis includes: a trolley beam, a plurality of floating wheel structures, the plurality of floating wheel structures being mounted on the trolley beam of the chassis, and the plurality of floating wheel structures being spaced apart along the length direction of the trolley beam; the floating wheel structures are capable of swinging up and down relative to the trolley beam to adapt to changes in ground undulation.

[0005] Preferably, the floating wheel structure includes a floating wheel support and a floating wheel, the floating wheel is mounted on the floating wheel support, and a plurality of floating wheel supports are spaced apart along the length direction of the trolley beam.

[0006] Preferably, a connecting shaft is provided in the middle of the floating wheel support, and the floating wheel support can swing around the connecting shaft.

[0007] Preferably, the floating wheel support is connected to the side of the trolley beam in the width direction via the connecting shaft.

[0008] Preferably, each floating wheel structure has two floating wheels, and the connecting shaft is located between the two floating wheels.

[0009] Preferably, each floating wheel structure has three floating wheels, which are arranged at equal intervals, with the middle floating wheel mounted on the connecting shaft.

[0010] Preferably, the chassis further includes: a tensioning wheel disposed at the end of the trolley beam along its length, the tensioning wheel being movable along the length of the trolley beam; and tracks covering the outside of the floating wheel structure and the tensioning wheel.

[0011] Preferably, the trolley beam includes at least two of the floating wheel structures.

[0012] According to a second aspect of the present invention, a tracked harvester is provided, wherein the tracked harvester includes a tracked harvester chassis as described above.

[0013] Preferably, the trolley beam is provided with four sets of floating wheel structures, and the center of gravity of the tracked harvester is located between the two middle floating wheel structures.

[0014] This utility model relates to a tracked harvester chassis and a tracked harvester, wherein multiple floating wheels are mounted on the chassis's trolley beam. The multiple floating wheels are spaced apart along the length of the trolley beam. When traversing uneven surfaces, the multiple floating wheels can swing according to the degree of unevenness, effectively reducing the bumps and impacts when crossing ridges, provided the swing angle does not exceed the swing limit. This improves the driving experience and protects machine components, effectively solving the problem that the existing tracked harvester's support roller assembly method is greatly affected by road undulations.

[0031] like Figures 1 to 4 As shown, according to a first aspect of the present invention, a tracked harvester chassis is provided, the tracked harvester chassis including a trolley beam 1 and multiple floating wheel structures 200.

[0032] In the following description, reference will be made to Figures 1 to 4 The specific structure of the aforementioned components of the tracked harvester chassis and their connection relationships are described in detail.

[0033] like Figures 1 to 4 As shown, in this embodiment, multiple floating wheel structures 200 can be installed on the trolley beam 1. Specifically, the multiple floating wheel structures 200 can be spaced apart along the length of the trolley beam 1. When the tracked harvester passes over a raised road surface 5, the multiple floating wheel structures 200 can swing up and down relative to the trolley beam 1 according to the degree of road surface protrusion to adapt to the undulations of the ground. Without exceeding the swing limit angle, the floating wheels 2 can effectively reduce the bumps and impacts of the tracked harvester when crossing ridges, thereby improving the driving experience and protecting machine components.

[0034] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the trolley beam 1 can be formed as a strip. The floating wheel structure 200 may include a floating wheel support 20 and a floating wheel 2, the floating wheel 2 being mounted on the floating wheel support 20. Multiple floating wheel supports 20 may be spaced apart along the length direction of the trolley beam 1. Specifically, the floating wheel support 20 may be mounted on the side of the trolley beam 1 in the width direction.

[0035] Furthermore, preferably, such as Figures 1 to 4 As shown, in an embodiment, a connecting shaft 21 can be provided in the middle of the floating wheel support 20, so that the floating wheel support 20 can swing around the connecting shaft 21 to reduce the feeling of bumps.

[0036] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the floating wheel support 20 can be mounted on the side of the trolley beam 1 in the width direction via a connecting shaft 21. Specifically, the connecting shaft 21 can pass through the trolley beam 1 and the floating wheel support 20 in the width direction of the trolley beam 1. The floating wheel support 20 is rotatably mounted on the trolley beam 1 via the connecting shaft 21, allowing the floating wheel support 20 to swing relative to the trolley beam 1. Preferably, multiple floating wheel supports 20 can be spaced apart along the length direction of the trolley beam 1.

[0037] Further optimized, such as Figures 1 to 4 As shown in the embodiment, in the plurality of floating wheel structures 200, each floating wheel structure 200 may include at least two floating wheels 2, so that the floating wheels 2 can provide sufficient support force to the trolley beam 1 during the swinging process of the floating wheel support 20. The plurality of floating wheels 2 are arranged one by one along the length direction of the trolley beam 1, and the plurality of floating wheel structures 200 swing one by one when passing over the raised road surface 5.

[0038] Furthermore, preferably, such as Figure 2 As shown, in one embodiment, the number of floating wheels 2 in each floating wheel structure 200 can be only two to save costs. In this case, the connecting shaft 21 can be located in the middle of the two floating wheels 2, allowing the two floating wheels 2 to swing around the connecting shaft 21. Furthermore, in another embodiment, the number of floating wheels 2 in each floating wheel structure 200 can be three. In this case, the three floating wheels 2 can be arranged at equal intervals. The floating wheel 2 located in the middle can be mounted on the floating wheel support 20 or the connecting shaft 21, allowing the floating wheels 2 on both sides to swing around the floating wheel 2 located in the middle, thereby reducing the feeling of bumps.

[0039] Further optimized, such as Figures 1 to 4 As shown in the embodiment, the trolley beam 1 includes at least two floating wheel structures 200. In actual use, as shown in the embodiment, four floating wheel structures 200 can be installed on the trolley beam 1. The center of gravity of the tracked harvester can be located between two adjacent floating wheel structures 200. Preferably, the center of gravity of the tracked harvester can be located between the two floating wheel structures 200 in the center to ensure that the whole machine can remain stable when passing over the raised road surface 5.

[0040] Preferred, such as Figures 1 to 4 As shown, in this embodiment, the tracked harvester chassis may further include a tensioning wheel 3 and a track 4. The tensioning wheel 3 can be located at the end of the trolley beam 1 along its length. The tensioning wheel 3 can move along the length of the trolley beam 1 to achieve a tensioning function. The track 4 can cover the exterior of the multiple floating wheel structures 200 and the tensioning wheel 3. The tensioning wheel 3 can be mounted to the trolley beam 1 via a mounting sleeve 31. Specifically, the mounting sleeve 31 can be set and fixed to the top of the trolley beam 1, and the tensioning wheel 3 can be movably mounted at the end of the mounting sleeve 31. The position of the tensioning wheel 3 can be adjusted by a set screw, allowing the tensioning wheel 3 to move along the length of the trolley beam 1 to tension the track 4.

[0041] In addition, such as Figures 1 to 4 As shown, according to a second aspect of the present invention, a tracked harvester is provided, the tracked harvester including the tracked harvester chassis as described above.

[0042] During use, when the tracked harvester passes over a raised road surface 5, the multiple floating wheel structures 200 can swing according to the degree of road surface protrusion. Under the premise of not exceeding the swing limit angle, the floating wheel 2 can effectively reduce the bumps and impacts of the tracked harvester when crossing the ridge, so as to improve the driving experience and protect the machine parts.
