Description

Technical Field

[0001] This utility model relates to the field of tractor technology, and in particular to a tractor hood mounting structure. Background Technology

[0002] In the field of agricultural machinery, tractors are core operating equipment, and their structural design directly affects operating efficiency, driving comfort, and ease of maintenance. Among them, the hood, as an important component of the tractor, is mainly used to protect core components such as the engine and transmission system from external dust and debris, and also plays a certain role in blocking the noise generated by the operation of the components. Therefore, the installation structure design of the hood is one of the key aspects of the overall tractor design.

[0003] Currently, most mainstream tractor hood installation methods on the market adopt an integrated design of the cab and hood. This means the hood is directly connected to the cab as a single unit, and then both are assembled onto the tractor chassis. This integrated design was common in early tractor development, and its advantages lie in its simple structure, fewer initial assembly steps, and ability to meet basic installation and fixation requirements. However, as agricultural production increasingly demands higher levels of driving comfort and ease of maintenance for tractors, the drawbacks of this traditional structure have gradually become apparent.

[0004] From a practical standpoint, the integrated installation design presents two core problems. Firstly, because the hood is rigidly connected to the cab, engine operation and road bumps during tractor operation cause continuous vibration in the hood. This vibration is transmitted directly to the cab through the connection structure, significantly increasing noise levels. Simultaneously, the vibration directly affects the driver and passengers, easily leading to fatigue during prolonged operation and severely impacting driving comfort. Secondly, the integrated structure prevents the hood from being disassembled separately. When maintenance is required on components such as the tractor engine and transmission system, the cab's connecting structures must be disassembled first. This not only increases maintenance steps and time but may also cause wear and tear on the cab or hood connections during disassembly and reassembly, reducing component lifespan.

[0005] In addition, the integrated design requires high installation precision. If there are slight deviations during the assembly process, it can easily lead to uneven gaps between the engine cover and the cockpit, which not only affects the appearance but may also allow external debris to enter the engine compartment and affect the normal operation of core components. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a tractor hood installation structure. By adopting a separate design between the hood and the cab, it solves the problems of high vibration and noise, and inconvenient maintenance in traditional tractor cabs. Specifically, this is achieved through the following technical solutions.

[0007] This utility model discloses a tractor hood mounting structure, which is used to mount the hood on the chassis and includes a first component, a second component and a third component. The first component includes a fixing frame and a fixing plate. The fixing frame is connected to the chassis via fastening bolts, and the fixing plate is fixed perpendicularly to the fixing frame. The second component includes a side plate and a transition frame, the transition frame being vertically fixed to the side plate, and the side plate including a vertical section, an inclined section and a horizontal section connected in sequence, the vertical section being bolted to a fixed plate; The third component includes a mounting plate and a mounting bracket. The mounting plate is bolted to the horizontal section of the side plate, and the mounting bracket is vertically fixed to the mounting plate, with its second end hinged to the inside of the hood.

[0008] Preferably, the mounting structure is symmetrically distributed about the center of the chassis.

[0009] Preferably, the third component further includes a support plate, which is fixed to the side of the mounting bracket near the second end and has a plurality of mounting holes thereon.

[0010] Preferably, the first end of the telescopic rod is hinged in the mounting hole, and the second end of the telescopic rod is hinged to the middle of the machine cover.

[0011] Preferably, the telescopic rod is a damped telescopic rod.

[0012] Preferably, the vertical section, inclined section and horizontal section of the side plate are integrally formed.

[0013] Preferably, the chassis is provided with a locking mechanism for locking the machine cover.

[0014] Preferably, the mounting bracket is provided with multiple fastening holes for bolting the chassis.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are: 1. The installation structure of this utility model cuts off the direct connection between the engine cover and the cab. The engine cover is directly installed on the tractor chassis through components such as fixing brackets, transition brackets, and side plates. This prevents the vibration generated by the engine cover when the tractor is working from being directly transmitted to the cab, thereby reducing the vibration and noise in the cab from the source. This creates a more comfortable working environment for the driver and passengers and helps to reduce fatigue during long-term work.

[0016] 2. The structure of this utility model supports the independent installation of the engine cover without relying on the assembly and positioning of the cockpit. During installation, it is only necessary to fix the relevant components to the chassis through the fastening holes on the mounting bracket, and then complete the hinge connection between the engine cover and the mounting bracket. The operation steps are simpler. At the same time, the mounting structure is symmetrically distributed on both sides of the chassis center, which can provide balanced support for the engine cover, avoid the engine cover from shifting or loosening after installation, and improve the overall stability of the engine cover after installation.

[0017] 3. The cover is hinged to the second end of the mounting bracket, allowing it to swing within a certain angle around the hinge axis. Combined with the support of the damping telescopic rod, this ensures that the cover stays stable when it is lifted up, preventing it from falling automatically and facilitating the maintenance and cleaning of the internal components of the engine compartment. When the cover is closed, the locking mechanism locks the cover to the chassis, preventing large-scale vibration of the cover during operation, thus balancing maintenance convenience and operational safety.

[0023] An embodiment of this utility model provides a tractor hood mounting structure, see [link to relevant documentation]. Figure 1 The mounting structure 200 is used to mount the hood 102 onto the chassis 101. On the one hand, it differs from the traditional integrated mounting design of the cab and hood, making it easier to install the hood separately, improving the convenience and stability of installation. On the other hand, it removes the direct connection between the cab and the hood, preventing the vibration of the hood from being directly transmitted to the cab during tractor operation, reducing cab noise and improving cab comfort.

[0024] For further explanation of the embodiments of this utility model, see [link to relevant documentation]. Figure 2 , Figure 3 and Figure 4 The mounting structure 200 includes a first component, a second component, and a third component. The first component includes a mounting bracket 201, fastening holes 202, and a mounting plate 203. Several fastening holes 202 are formed on the mounting bracket 201 for fastening the mounting bracket 201 to the chassis 101 by bolts. The side of the mounting bracket 201 near the cover 102 is fixedly connected to the mounting plate 203. The mounting plate 203 is set perpendicular to the mounting bracket 201.

[0025] A second component is provided on the side of the first component near the hood 102. The second component includes a side plate 204 and a transition frame 205.

[0026] The side of the transition frame 205 is fixedly connected to the side plate 204. The transition frame 205 is perpendicular to the side plate 204. The side plate 204 includes a vertical section, an inclined section and a horizontal section. The inclined section is located between the vertical section and the horizontal section, and the vertical section, the inclined section and the horizontal section are connected end to end in sequence.

[0027] The vertical section of the side plate 204 is fastened to the fixing plate 203 with bolts to achieve relative fixation of the first component and the second component, thereby simultaneously locking the first component and the second component onto the chassis 101, providing a stable foundation for the installation of the cover 102.

[0028] A third component is installed above the horizontal section of the side plate 204. The third component includes a mounting plate 206 and a mounting bracket 207. The mounting plate 206 is fastened to the horizontal section of the side plate 204 by bolts. The side of the mounting plate 206 away from the side plate 204 is fixed to the first end of the mounting bracket 207. The mounting bracket 207 is set perpendicular to the mounting plate 206. The second end of the mounting bracket 207 is hinged to the inside of the cover 102, so that the cover 102 can swing around the hinge axis within a certain angle, which facilitates the opening and closing of the cover 102.

[0029] The third component also includes a support plate 208 and mounting holes 209. The side of the mounting bracket 207 near the second end is fixed to the support plate 208. The support plate 208 has several mounting holes 209, one of which is hinged to the first end of the telescopic rod 210, and the second end of the telescopic rod 210 is hinged to the middle of the cover 102.

[0030] Among them, such as Figure 4 The mounting structure 200 shown is symmetrically distributed on both sides of the center of the chassis 101, and is used to jointly support and install the hood 102, ensuring that the installation of the hood 102 is more stable and the use is more convenient.

[0031] The telescopic rod 210 is a damping telescopic rod, which ensures that when the cover 102 is lifted upwards, the telescopic rod 210 can support the cover 102 and prevent the cover 102 from falling down automatically.

[0032] In addition, a locking mechanism is also installed on the chassis 101. When the hood 102 is closed downwards, the chassis 101 and the hood 102 are locked together by the locking mechanism to prevent the hood 102 from vibrating significantly during the operation of the tractor, which would affect its stability. The locking mechanism is existing technology and will not be described in detail here.

[0033] This utility model provides stable support for the installation of the engine cover 102 through the cooperation between the first component, the second component and the third component, and indirectly installs the engine cover 102 on the chassis 101, cutting off the direct connection between the engine cover 102 and the cockpit, thereby reducing the vibration of the cockpit and improving the driving experience.

[0034] In addition, the hinge between the hood 102 and the second end of the mounting bracket 207, and the support of the telescopic rod 210, together enable the hood 102 to be installed, allowing it to be opened and closed within a certain range, which facilitates the maintenance and upkeep of the tractor.

[0035] The embodiments described above are not exhaustive, nor do they limit the scope of the present invention to the specific embodiments described herein. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to effectively utilize the present invention and its modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
