Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically a tractor air guide structure based on a hydraulic motor-driven fan. Background Technology

[0002] Currently, applying hydraulic motor-driven fans to tractors has become a technological approach. Compared to engine-driven fans, hydraulic motor-driven fans are not limited by engine speed, which can improve airflow and heat dissipation performance to a certain extent. They can also achieve forward and reverse rotation of the fan, improving the convenience of radiator maintenance.

[0003] The current existing layout is as follows Figure 1 From left to right, the components are: radiator 1, air guide shroud body 2, fan 3, hydraulic motor bracket 4, hydraulic motor 5, engine and pulley system 6. The shortcomings of the existing technology are: due to the compact layout within the tractor hood, the space between the radiator and engine is limited, and the motor is located outside the air guide shroud, requiring relatively ample space. Furthermore, a minimum distance must be maintained between the fan and the radiator core surface. Therefore, this arrangement results in a high space requirement between the engine and radiator, indirectly leading to a high space requirement for the front of the engine within the hood, which to some extent restricts the application of this technical approach.

[0004] Patent CN203239609U discloses a wind deflector assembly for engineering machinery. This solution arranges the motor inside the wind deflector. By overlapping the motor with the wind deflector, the technical route can be realized in a limited space, but it brings problems such as difficulty in maintaining the hydraulic motor and the fan.

[0005] The information disclosed in the above background section is only intended to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] To address the aforementioned shortcomings, the present invention aims to provide a tractor air guide structure based on a hydraulic motor-driven fan, which solves the problem of needing to achieve a compact arrangement of key components while ensuring a certain degree of ease of maintenance in the case of a hydraulic motor-driven fan.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A tractor air guide shroud structure based on a hydraulic motor-driven fan includes an air guide shroud body, a hydraulic motor, and a fan. One end of the air guide shroud body is used for mounting and connecting to a radiator, and the other end is set as an air guide section. An H-shaped bracket is provided inside the air guide shroud body. The hydraulic motor is fixed on the H-shaped bracket by a transverse mounting bracket, and the fan is mounted on the output shaft of the hydraulic motor. A detachable air guide shroud cover is also provided on the top of the air guide shroud body. The air guide shroud cover and the air guide shroud body together form the air guide section that accommodates the fan.

[0009] Specifically, the top of the air guide cover is provided with mounting ears, and the top of the air guide body is provided with a first mounting hole corresponding to the mounting ears. The mounting ears and the first mounting hole are connected together by bolts and nuts.

[0010] Specifically, the upper cover of the air guide shroud has vertically arranged mounting holes on both sides, and the main body of the air guide shroud has vertical hole connecting pieces corresponding to the vertical mounting holes. The vertical mounting holes and the vertical hole connecting pieces are connected together by bolts and nuts.

[0011] Specifically, the upper and lower supports of the H-shaped bracket are respectively mounted on the air guide cover body via L-shaped mounting bases.

[0012] Specifically, the top of the air guide shroud is also equipped with a pressure plate connector for connecting to the hydraulic pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention addresses the challenge of using hydraulic drive motors and fans in tractors. It features a compact design that integrates the air guide shroud, fan, and motor while prioritizing ease of maintenance. The novel and rationally arranged structure is easy to implement. The air guide shroud is a split design; by opening the top cover, the fan can be removed, freeing up space for maintenance of the hydraulic motor and its piping. In particular, the maintenance operation design prioritizes convenience and efficiency in practical operation. All maintenance steps can be completed directly on the vehicle, eliminating the need for hoisting and disassembling the air guide shroud or radiator. Simply removing the top cover of the air guide shroud allows for easy fan removal, ensuring ample space for inspection and maintenance of the hydraulic motor and its piping. This design significantly reduces maintenance difficulty and disassembly time, avoiding the complex operations that may require disassembling most of the equipment in traditional methods, ensuring quick and convenient maintenance under on-site conditions. If necessary, the hydraulic motor and its support can also be directly removed without additional equipment or operating space. In summary, this structure solves the problem of achieving a compact arrangement of key components in a hydraulic motor-driven fan circuit while ensuring a certain degree of ease of maintenance.

[0023] like Figure 2-6 As shown in the figure, this embodiment discloses a tractor air guide structure based on a hydraulic motor-driven fan, including an air guide body 2, a hydraulic motor 5, and a fan 3.

[0024] One end of the air guide shroud body 2 is used for installation and connection with the heat sink 1, and the other end is set as the air guide section. An H-shaped bracket 8 is provided inside the air guide shroud body 2. The hydraulic motor 4 is fixed on the H-shaped bracket 8 by a horizontal mounting bracket 9. The fan 3 is mounted on the output shaft of the hydraulic motor 5. A detachable air guide shroud cover 7 is also provided on the top of the air guide shroud body 2. The air guide shroud cover 7 and the air guide shroud body 2 together form the air guide section that accommodates the fan 3.

[0025] During installation, the H-shaped bracket 8, welded from square steel, is fixed inside the air guide shroud body 2 via the L-shaped mounting base 16. The hydraulic motor 5 and the transverse mounting bracket 9 are then fixed on it, and the fan 3 is assembled onto the hydraulic motor 5. Therefore, the hydraulic motor 5 is housed inside the air guide shroud, saving limited space within the tractor's hood. Furthermore, by removing the air guide shroud cover 7, the fan 3 can be pulled out from the upper space, freeing up space for maintenance of the hydraulic motor 5 and its piping. If necessary, there is also sufficient space to remove the hydraulic motor along with its bracket. In summary, this structure solves the problem of achieving a compact arrangement of key components in a hydraulic motor-driven fan circuit while ensuring a certain degree of maintenance convenience.

[0026] As a preferred technical solution in this embodiment, the top of the air guide cover 7 is provided with mounting ears 10, and the top of the air guide body 2 is provided with a first mounting hole 11 corresponding to the mounting ears 10. The mounting ears 10 and the first mounting hole 11 are connected together by bolts and nuts. Vertical mounting holes 12 are provided on both sides of the air guide cover 7, and vertical hole connecting pieces 13 are provided on the air guide body 2 corresponding to the vertical mounting holes 12. The vertical mounting holes 12 and the vertical hole connecting pieces 13 are connected together by bolts and nuts. Through a simple bolt installation method, the arrangement is reasonable, the structure is compact, and it is easy to implement.

[0027] The upper and lower supports of the H-shaped bracket are mounted on the air guide shroud body via L-shaped mounting bases. The horizontal mounting bracket 9 includes a recessed slot 14, and its two ends are mounted on the two vertical beams of the H-shaped bracket 8. The hydraulic motor 5 is fixed to the recessed slot 14, and its output shaft passes through the recessed slot 14 and connects to the fan 3. An H-shaped bracket made of square steel is mounted on top of this, ensuring the bracket's strength while minimizing impact on the wind field.

[0028] In addition, the top of the air guide shroud body 2 is also provided with a pressure plate connector 15 for connecting to the hydraulic pipe. The hydraulic pipe connected to the hydraulic motor needs to pass through the air guide shroud. Using the pressure plate connector as a transition for pipe passage can ensure the air guide shroud's sealing performance.

[0029] Although the present invention has been described in detail above with specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
