Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a multi-power universal chassis for harvesters. Background Technology

[0002] The harvester chassis is the core load-bearing and power transmission hub of the entire machine, supporting all working components and enabling the machine's movement and operation. Its specific functions can be divided into: 1. Load bearing and support: Fixing and supporting all components such as the engine, cab, header, and grain bin, ensuring the stability of the overall structure and withstanding impacts and loads during operation. 2. Power transmission: Distributing the power output from the engine to the wheels (or tracks) and working devices such as the header and threshing drum through components such as the gearbox and drive shaft, driving the machine's movement and various operational tasks. 3. Movement and steering: Achieving movement of the entire machine through the wheel or track structure, and flexibly adjusting the direction of travel with the steering system to ensure operation along a track in the field and adapt to different terrain environments.

[0003] Currently, existing harvesters typically have their engines directly mounted on the chassis. However, different regions have different preferences and requirements for the engine models used in harvesters, resulting in the need to match different brands of power for the same harvester in order to meet diverse market demands and improve the competitiveness of its products.

[0004] Different brands of engines have different support interface sizes, thus requiring chassis of different sizes to adapt to different brands of engines; chassis are not interchangeable. Furthermore, chassis are typically manufactured by welding. Whether remanufacturing a chassis or cutting and welding an existing chassis, both lead to excessively long production cycles, high costs, and reduced product competitiveness. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a universal harvester chassis that can be matched with different engine models.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-power universal chassis for harvesters, including a chassis body, on the upper side of which an engine transition frame and a radiator transition frame are detachably mounted; the engine transition frame is provided with several support seats for connecting with the engine's support legs to support the engine; the radiator transition frame is used to install the radiator.

[0007] The beneficial effects of this solution are as follows: the engine transition bracket separates the chassis body from the engine, and the radiator transition bracket separates the chassis body from the radiator; when it is necessary to change the model of the engine or radiator, only the engine transition bracket and the radiator transition bracket need to be replaced, instead of replacing the entire chassis body, thereby reducing costs, shortening the manufacturing cycle, and improving product competitiveness.

[0008] Preferably, the engine transition frame is provided with four support seats on its upper side.

[0009] The advantages of adopting the above-mentioned preferred scheme are: the four support bases are distributed in a rectangular shape, resulting in more stable support.

[0010] Preferably, the support base and the engine transition frame are detachably connected.

[0011] The advantages of adopting the above-mentioned preferred solution are: each support can be disassembled and replaced individually, which facilitates maintenance; and it further improves the versatility of the engine transition bracket.

[0012] Preferably, the engine transition frame has a first connecting hole at each of the four support seats; the support seats are fixedly connected to the first connecting holes by bolts.

[0013] The advantages of adopting the above preferred solution are: the support base is fixed through the first connecting hole, the structure is simple, and the assembly difficulty and manufacturing cost are reduced.

[0014] Preferably, the heat dissipation tank transition frame is elongated and has two second connection holes on its upper side, and the heat dissipation tank is fixedly connected to the second connection holes by bolts.

[0015] The advantage of adopting the above preferred solution is that the heat dissipation tank is fixed through the second connection hole, which reduces the assembly difficulty. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] Example 1 like Figures 1 to 2 As shown, a multi-power universal chassis for harvesters includes a chassis body 1. An engine transition frame 2 and a radiator transition frame 3 are detachably mounted on the upper side of the chassis body 1. The engine transition frame 2 is provided with several support seats 4 for connecting to the engine's support legs 6 to support the engine 5. The radiator transition frame 3 is used to install a radiator 7.

[0020] In this embodiment, the chassis body 1 is used to fix and support all components such as the engine, cab, cutting platform, and grain bin. The engine transition frame 2 is fixed to the chassis body 1 with bolts, and multiple support seats 4 are fixed on the engine transition frame 2. Two support legs 6 are respectively provided on both sides of the bottom of the engine 5, and the support legs 6 are fixed to the support seats 4 by shock absorption devices. The radiator transition frame 3 is also fixed to the chassis body 1 with bolts; the radiator 7 is fixed to the radiator transition frame 3 with bolts; forming a whole.

[0021] When it is necessary to replace the engine 5 with another model, since the size and position of the support legs 6 at the bottom of different engines 5 are different, it is also necessary to replace it with an engine transition bracket 2 that corresponds to the position of the support legs 6 of the new engine 5, so that its support base 4 can be connected to the support legs 6 of the engine.

[0022] The same applies to the cooling water tank transition bracket 3; if the size of the cooling water tank 7 is changed, the cooling water tank transition bracket 3 corresponding to its size needs to be replaced. By replacing the cooling water tank transition bracket 3 with one of different heights, the position of the cooling water tank 7 can be changed to adapt to different installation requirements; the upper side of the cooling water tank transition bracket 3 is also equipped with a shock-absorbing rubber pad.

[0023] Its advantages include not having to replace the entire chassis body, reducing costs, shortening the manufacturing cycle, and improving product competitiveness.

[0024] Based on this embodiment, the detachable connection includes bolt connection and pin connection.

[0025] Example 2 like Figure 3 and Figure 4 As shown, based on Embodiment 1, the engine transition frame 2 is provided with four support seats 4 on its upper side.

[0026] In this embodiment, the engine transition frame 2 is a frame structure welded from channel steel. In this design, four channel steels are welded into a rectangular frame, resulting in better overall mechanical performance and the ability to fully support the weight of the engine 5. The four support seats 4 are rectangularly distributed at the four corners, providing more stable support.

[0027] In addition, the two side support seats 4 are arranged in a V-shape, which makes the engine 5 more stable.

[0028] Based on this embodiment, the frame structure of the engine transition frame 2 can also be polygonal or other shapes.

[0029] like Figure 3 and Figure 4 As shown, the support base 4 and the engine transition frame 2 are detachably connected.

[0030] In this embodiment, each support 4 is fixed to the engine transition frame 2 by bolts and can be disassembled and replaced individually. Supports 4 of different heights can be replaced to adapt to the height position of the support legs 6 at the bottom of different engines 5; and further improve the versatility of the engine transition frame 2.

[0031] Specifically, detachable connections include bolted connections and pin connections.

[0032] like Figure 3 and Figure 4 As shown, the engine transition frame 2 has first connecting holes 8 at the positions of the four support seats 4; the support seats 4 are fixedly connected to the first connecting holes 8 by bolts.

[0033] In this embodiment, the first connecting hole 8 is an oblong hole, and the length direction of the first connecting hole 8 is parallel to the length direction of the engine transition bracket 2, which facilitates the left and right adjustment of the position of the support seat 4 to adapt to engines 5 of different sizes, thereby reducing assembly difficulty and manufacturing costs.

[0034] As a parallel technical solution in this embodiment, two parallel slide rails can also be set on the top of the engine transition frame 2, and the support seats 4 on both sides can be slidably located on the slide rails and their positions can be fixed by pins, which can also realize the left and right adjustment of the support seats 4.

[0035] Example 3 like Figure 5As shown, based on Embodiment 1, the radiator transition frame 3 is elongated, two second connecting holes 9 are provided on the upper side of the radiator transition frame 3, and the radiator 7 is fixedly connected with the second connecting holes 9 by bolts.

[0036] In this embodiment, the second connecting holes 9 are waist-shaped holes, the length direction of the second connecting holes 9 is perpendicular to the length direction of the radiator transition frame 3, and the installation position of the radiator 7 can be moved back and forth through the second connecting holes 9, so as to adjust the spacing between the radiator and the engine 5, ensure the heat dissipation effect, and also reduce the assembly difficulty.

[0037] As Figure 5 shown, the radiator transition frame 3 is formed by integral bending.

[0038] In this embodiment, the radiator transition frame 3 is an elongated steel plate bent into an I-shape, both ends of the bent steel plate serve as installation positions for connecting bolts, and the middle part serves as a supporting position for the radiator 7; the integral forming has high production speed and low cost.

[0039] As a parallel technical solution of this embodiment, the radiator transition frame 3 can also be manufactured by integral welding to improve structural strength.

[0040] As Figure 5 shown, a plurality of reinforcing rib plates 10 are welded on the radiator transition frame 3.

[0041] In this embodiment, the reinforcing rib plates 10 are welded on both the outer side and the inner side of the I-shaped radiator transition frame 3 to form a frame structure, which increases structural strength and can bear a heavier radiator 7.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present utility model rather than limit the technical solution. Those skilled in the art should understand that modifications or equivalent substitutions made to the technical solution of the present utility model without departing from the purpose and scope of the technical solution shall all be included in the scope of claims of the present utility model.
