Description

Technical Field

[0001] This utility model mainly relates to the field of tracked chassis technology, specifically to a tracked chassis with slope adaptation design. Background Technology

[0002] Tracked chassis, as a walking structure with excellent passability and strong load-bearing capacity, are widely used in modern production activities. In common tracked chassis application cases, two sets of track modules usually use an integral core frame as the core structure and are installed on both sides. When this type of structure is used in mountainous environments, such as when tracked chassis are used to carry fertilizer and pesticide spreading equipment in camellia plantations, the equipment is very prone to slippage when operating on mountain slopes with large slopes.

[0003] The inventors proposed a tracked chassis with a slope-adaptive design. By adopting a liftable and deflectable structural design between the track module and the equipment mounting plate, the obstacle-crossing ability of the equipment is improved and the slippage of the equipment due to excessive tilting on mountain slopes is avoided. Utility Model Content

[0005] This invention provides a tracked chassis with a slope-adaptive design, which solves the technical problem of existing equipment's integral tracked chassis being prone to tipping over and slipping on mountain slopes.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is: a tracked chassis with slope-adaptive design, comprising the following structure:

[0008] The pallet has receiving plates fixed on both the left and right sides of its bottom, and a truss is fixed at the bottom of the receiving plates.

[0009] The track module is symmetrically arranged on the left and right sides of the center of the pallet. A core frame is fixed in the center of the track module, and auxiliary frames are fixed on the opposite sides of the two core frames.

[0010] Furthermore, lifting hydraulic rods are fixedly installed at both the front and rear ends of the middle section of the truss.

[0011] Furthermore, a buffer ring is fixed in the middle of the ball head, and the front and rear sides of the buffer ring abut against the bottom of the connecting rod and the top of the support rod, respectively.

[0012] Furthermore, a deflection hydraulic rod is movably connected to the middle of the truss, and a deflection shaft is movably connected to the bottom output end of the deflection hydraulic rod.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This utility model provides a tracked chassis with a slope-adaptive design. The lifting hydraulic rod pushes the connecting rod to move on the truss.

[0035] See attached document Figure 1-5 This utility model provides a tracked chassis with a slope-adaptive design, comprising the following structure:

[0036] The pallet 1 has a support plate 2 fixed on both the left and right sides of its bottom, and a truss 3 fixed on the bottom of the support plate 2.

[0037] Track module 7 is symmetrically arranged on the left and right sides of the center of pallet 1. A core frame 71 is fixed in the center of track module 7, and auxiliary frames 8 are fixed on the opposite sides of the two core frames 71.

[0038] In this embodiment, lifting hydraulic rods 4 are fixedly installed at both the front and rear ends of the middle part of the truss 3. The output end of the lifting hydraulic rod 4 is movably connected to a docking rod 5. The connection between the docking rod 5 and the lifting hydraulic rod 4 is slidably connected to the outside of the truss 3. A ball head 51 is movably connected to the bottom of the docking rod 5, and a support rod 53 is movably connected to the bottom of the ball head 51.

[0039] The lifting hydraulic rod 4 pushes the connecting rod 5 to move on the truss 3. The connecting rod 5 and the ball head 51 work together to drive the strut 53 to move. At this time, the deflection hydraulic rod 6 needs to work with the lifting hydraulic rod 4 to extend and retract, so as to complete the adjustment of the working height of the truss 3 on the auxiliary frame 8, which facilitates the equipment to perform obstacle crossing operations.

[0040] In this embodiment, a buffer ring 52 is fixedly provided in the middle of the ball head 51, and the front and rear sides of the buffer ring 52 abut against the bottom of the connecting rod 5 and the top of the support rod 53, respectively.

[0041] The ball head 51 and the buffer ring 52 work together to prevent the top of the strut 53 from colliding with the bottom of the connecting rod 5, so as to facilitate the normal lifting and lowering of the truss 3 on the auxiliary frame 8.

[0042] In this embodiment, a deflection hydraulic rod 6 is movably connected to the middle of the truss 3, and a deflection shaft 61 is movably connected to the bottom output end of the deflection hydraulic rod 6.

[0043] When the track module 7 is working better on the mountain slope, the deflection hydraulic rod 6 and the deflection shaft 61 work together to adjust the relative assembly angle between the auxiliary frame 8 and the truss 3, so as to achieve the fit between the track module 7 and the mountain slope, improve the stability of the equipment on the mountain slope, and avoid the equipment from excessive tilting and slipping on the mountain slope.

[0044] In this embodiment, the outer side of the auxiliary frame 8 is fixedly connected to the outer side of the core frame 71. The front and rear ends of the auxiliary frame 8 are both fixedly provided with first mounting seats 81. The rear side of the first mounting seat 81 is movably connected to the bottom of the support rod 53. The opposite sides of the two auxiliary frames 8 are both fixedly provided with second mounting seats 82. The middle part of the second mounting seat 82 is movably connected to the outer side of the deflection shaft 61. The front end of the auxiliary frame 8 is fixedly provided with a drive motor 83. The front output end of the drive motor 83 is fixedly provided with a reducer 84. The output end of the reducer 84 is fixedly connected to the drive wheel shaft of the track module 7.

[0045] The drive motor 83 and the reducer 84 work together to drive the track module 7. The auxiliary frame 8 is rigidly connected to the core frame 71. The lifting hydraulic rod 4 and the deflection hydraulic rod 6 are used as the driving source to adjust the working height of the pallet 1 and the working angle between the track module 7 and the pallet 1.

[0046] The first mounting base 81 cooperates with the support rod 53, and the second mounting base 82 cooperates with the deflection shaft 61. When adjusting the working height of the support plate 1, the lifting hydraulic rod 4 and the deflection hydraulic rod 6 need to work together. When adjusting the relative assembly angle between the truss 3 and the auxiliary frame 8, the deflection hydraulic rod 6 needs to work.

[0047] Detailed operating procedures:

[0048] The lifting hydraulic rod 4 pushes the connecting rod 5 to move on the truss 3. The connecting rod 5 and the ball head 51 cooperate to drive the strut 53 to move. At this time, the deflection hydraulic rod 6 needs to cooperate with the lifting hydraulic rod 4 to extend and retract, so as to complete the adjustment of the working height of the truss 3 on the auxiliary frame 8. When the track module 7 is working better on the mountain slope, the deflection hydraulic rod 6 and the deflection shaft 61 cooperate to complete the adjustment of the relative assembly angle between the auxiliary frame 8 and the truss 3, so as to realize the fit between the track module 7 and the mountain slope and improve the stability of the equipment on the mountain slope.

[0049] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
