Description

Technical Field

[0001] This invention relates to the field of tractor technology, and in particular to a tractor under-wind protection system. Background Technology

[0002] As is well known, during tractor operation, the engine runs continuously and requires cooling. At this time, the cooling fan rotates at extremely high speeds, generating a massive airflow that blows a large amount of air directly onto the ground. Since tractors typically operate in harsh environments such as fields and orchards, where there is a lot of dust on the ground, strong winds stir up this dust, causing numerous problems. Firstly, dust is drawn into the vehicle's air filter system, leading to premature engine wear, which not only shortens the engine's lifespan but also affects its operating efficiency. Secondly, a large amount of dust floating in the air severely impairs the tractor driver's visibility, making it difficult to operate the tractor accurately and posing a significant safety hazard. Furthermore, dust also hinders heat dissipation from components, and if inhaled by the driver, it can harm their health. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art and solve the existing technical problems, the present invention discloses a tractor under-blowing protection system, which ensures heat dissipation while avoiding dust and improving the safety of equipment and personnel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A tractor under-ventilation protection system includes a bracket for mounting the engine cooling mechanism of the tractor, and a front engine cover mounted on the bracket. The cooling mechanism includes a radiator and a cooling fan. A sealing strip is provided between the edge of the front engine cover opening and the bracket. Vertical protective mesh plates are provided on both sides of the cooling fan. A flow-guiding plate is fixedly connected to the bottom inner side of the protective mesh plate. A flow-guiding base plate is provided at the front end of the flow-guiding plate. The flow-guiding plate and the flow-guiding base plate are both fixedly connected to the bracket. An integrated sealed bridge frame of the tractor is provided between the flow-guiding base plate and the flow-guiding plate. A transition plate is provided at the rear end of the flow-guiding plate, and the rear end of the transition plate corresponds to the tractor's fuel tank.

[0005] Furthermore, a sealing element is provided between the side of the radiator and the casing.

[0006] Furthermore, the sealing element is configured as a sealing brush or a sealing sponge.

[0007] Furthermore, the front end face of the oil tank is provided with a stepped structure, and the lower vertical surface of the stepped mechanism is set as an arc surface.

[0008] Furthermore, the rear end of the drainage plate is rotatably connected to a self-adjusting plate via a horizontal rotating shaft. A torsion spring is fitted onto the horizontal rotating shaft, and the two protruding ends of the torsion spring are respectively engaged with the drainage plate and the self-adjusting plate, so that the self-adjusting plate can be tilted up from the horizontal state by an angle of 10 to 30 degrees by the torsion spring.

[0009] Furthermore, the rear end of the upper surface of the self-adjusting plate is provided with an arc transition angle.

[0010] Furthermore, a curtain is provided on the outer side of the drainage plate, and a support rod is fixed on the upper inner side of the curtain. One end of the support rod is rotatably connected to the drainage plate through a first hinge shaft coaxial with the horizontal rotating shaft, and the other end of the support rod is fixed with a second hinge shaft. The side of the self-adjusting plate is provided with an elongated hole adapted to the sliding engagement of the second hinge shaft.

[0011] By employing the technical solution described above, the present invention has the following beneficial effects: The tractor under-blowing protection system disclosed in this invention first uses a sealing strip to seal the gap between the front hood and the bracket, preventing the engine radiator intake side from drawing air from the gap close to the ground and causing dust. Then, a guide plate is used to disperse the air from the engine fan to the left and right sides of the engine, changing the direction of airflow and preventing the air from blowing directly to the ground and stirring up dust. This improves the working efficiency of the air filter, allowing the airflow guide plate connected to the protective mesh to guide the airflow to the horizontal direction. Under the constraint of the transition plate, the flowing air can provide good heat dissipation for the engine fuel tank, ensuring its normal working condition, improving driving safety, and protecting the driver's health.

[0014] The technical solution of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the accompanying drawings of the present invention for the convenience of describing the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation. Example 1:

[0015] Combined with appendix Figure 1 The tractor under-air cooling system includes a bracket 2 for mounting the tractor's engine cooling mechanism, and a front hood 1 covering the bracket 2. The front hood 1 allows air intake from both its front end and top. The cooling mechanism includes a radiator and a cooling fan. A sealing strip is provided between the edge of the front hood 1 and the bracket 2. Specifically, a thickened rubber sealing strip is added to the bottom edge of the front hood 1, ensuring a tight seal between the front and left / right sides of the front hood 1 and the sealing plate of the bracket 2, forming a complete sealed structure. In this way, the air intake side of the radiator and the front hood 1 form a relatively independent air chamber, allowing air to primarily enter from the top when the cooling fan is running. The air intake is designed to prevent air from being drawn in from the front and sides of the engine radiator due to negative pressure, thus avoiding the stirring up of dust. As needed, a seal is installed between the radiator side and the engine cover. Specifically, the seal is a sealing brush or a sealing sponge. The application of these sealing materials ensures a tight seal between the left and right ends of the radiator's front air intake and the engine cover, eliminating air leakage. This not only prevents hot air backflow but also avoids affecting the overall performance of the machine, effectively solving the problem of high temperatures caused by hot air backflow and ensuring the stability and reliability of the tractor during operation. Vertical protective mesh plates 5 are installed on both sides of the cooling fan to prevent the driver from accidentally touching the cooling fan and getting injured. A guide plate 8 is fixedly connected to the bottom inner side of the protective mesh plate 5. A guide base plate 3 is located at the front end of the guide plate 8. Both the guide plate 8 and the guide base plate 3 are fixedly connected to the bracket 2. The guide base plate 3 is welded to the bracket 2, positioning it between the bottom of the engine cooling fan and the ground, acting as a barrier. When the fan is running, the guide base plate 3 disperses the airflow from the engine fan to the left and right sides of the engine, changing the airflow direction and preventing the air from blowing directly onto the ground and stirring up dust. The guide plate 8 effectively guides the airflow from the cooling fan, directing the originally downward-blowing airflow to a horizontal direction, further optimizing the airflow direction and reducing the direct impact of the airflow on the ground. An integrated sealed bridge frame 4 of the tractor is installed between the guide base plate 3 and the guide plate 8. The bridge frame 4 is fixed to the bracket 2, which not only enhances the structural stability of the front axle, but also provides strong auxiliary support for the overall airflow guidance, heat dissipation, and downward airflow structure, enabling them to work together better to prevent the engine fan from blowing up ground dust. The rear end of the airflow guide plate 8 is equipped with a transition plate 6, the rear end of which corresponds to the tractor's fuel tank 7. The fuel tank 7 can be integrated with the airflow guide plate 8 through the transition plate 6, effectively constraining the overall airflow direction and causing it to flow horizontally backward along a predetermined path. This provides good heat dissipation for the engine and fuel tank 7, avoiding various problems that may be caused by high temperature and ensuring the normal operation of the engine and fuel tank 7. If necessary, the front end of the fuel tank 7 is equipped with a stepped structure, and the lower vertical surface of the stepped mechanism is set as an arc surface, increasing the contact area with the flowing air and guiding the airflow direction.

[0016] The tractor downdraft protection system of this invention is carefully designed and developed based on the working characteristics and environmental requirements of tractor operation. The system consists of several key components, including a bracket 2, radiator, front hood 1, guide plate 3, sealed front axle, protective mesh 5, deflector plate 8, and fuel tank 7. In actual assembly, the components must be installed in a specific order: first, the bracket 2 is installed, and then the integrated sealed front axle, radiator, fuel tank 7, protective mesh 5, deflector plate 8, and front hood 1 are assembled in sequence. All assembled parts are essential components of the tractor. By appropriately modifying these components and ensuring their coordination, the system can optimize wind direction and prevent downdraft from stirring up sand and dust, thereby effectively improving the overall performance and effectiveness of the tractor during operation. Example 2:

[0017] As attached Figure 2-4As shown in Embodiment 1, a self-adjusting plate 11 is rotatably connected to the rear end of the flow-guiding plate 8 via a horizontal rotating shaft 10. A torsion spring 9 is fitted onto the horizontal rotating shaft 10, and the two protruding ends of the torsion spring 9 are respectively engaged with the flow-guiding plate 8 and the self-adjusting plate 11. This allows the self-adjusting plate 11 to tilt upwards from a horizontal position by 10 to 30 degrees, relying on the torsion spring 9. When the cooling fan's airflow is low, to prevent the air from diffusing downwards before reaching the oil tank 7, the tilted self-adjusting plate 11 guides the airflow upwards in advance, extending the descent time of the flowing air at slow flow rates, allowing it to reach the oil tank 7 for cooling. Conversely, when the cooling fan's airflow is high, the thrust of the wind allows the self-adjusting plate 11 to lie flat, ensuring horizontal airflow and preventing excessive airflow. The airflow is high-speed and obliquely upward. As needed, the rear end of the upper surface of the self-adjusting plate 11 is provided with an arc transition angle to ensure smooth airflow. In addition, a curtain 12 is provided on the side of the air-guiding plate 8. A support rod 13 is fixed on the upper inner side of the curtain 12. One end of the support rod 13 is rotatably connected to the air-guiding plate 8 through a first hinge shaft coaxial with the horizontal rotating shaft 10. The other end of the support rod 13 is fixed with a second hinge shaft. The side of the self-adjusting plate 11 is provided with an elongated hole 14 adapted to the sliding engagement of the second hinge shaft. This allows the second hinge shaft to slide along the elongated hole 14 when the self-adjusting plate 11 rotates adaptively, thus enabling adaptive adjustment. This is mainly to ensure that when the cooling fan wind force is small and the self-adjusting plate 11 tilts up, it blocks the wind from the side of the air-guiding plate 8, preventing the slower-flowing air from escaping from the side.
