Description

Technical Field

[0001] The utility model relates to the field of agricultural harvesting machinery and equipment, in particular to a hydraulically driven radiator fan device. Background Art

[0002] At present, agricultural harvesters on the domestic market are usually equipped with radiators. Radiators are generally integrated with water cooling, air cooling, hydraulic oil cooling, air conditioning, etc. In order to reduce the temperature of the radiator itself, a fan is usually set. The fan is generally driven directly by the engine through a flange connection. The layout of the fan is limited by the layout of the engine, and the fan speed is always consistent with the engine speed. The fan speed cannot be adjusted according to the heat dissipation required by the radiator. Utility Model Content

[0003] The purpose to be achieved by the present invention is to provide a solution to the problem in the prior art that the rotation speed of the fan cannot be adjusted individually, thereby realizing the individual adjustment of the rotation speed of the fan.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a hydraulically driven radiator fan device, comprising a frame, a hydraulic motor and a fan mounted on the frame, the output end of the hydraulic motor being connected to the input end of the fan through a transmission shaft, a speed disc being fixedly provided on the transmission shaft, a speed sensor being provided on one side of the speed disc, and the speed sensor being used to measure the speed of the speed disc.

[0005] After adopting the above technical solution, the utility model has the following advantages: the fan is driven by a hydraulic motor, and the fan speed can be flexibly adjusted according to the actual heat dissipation demand, and is no longer restricted by the engine speed. Secondly, the speed sensor monitors the speed of the speed dial in real time, which can achieve precise control of the fan speed and adjust the heat dissipation efficiency according to actual needs. At the same time, the speed dial is usually designed with precise scales or marks. The speed sensor calculates the speed by detecting these marks, which can provide higher measurement accuracy. Finally, the fan is not strictly restricted by the engine layout, and the fan can be more freely arranged in the position that is most conducive to heat dissipation, optimizing the airflow path and improving the overall heat dissipation effect.

[0006] Furthermore, it also includes a mounting base for mounting the hydraulic motor, the mounting base and the frame are detachably connected, the mounting base is provided with a through hole for the transmission shaft to rotate through, and the speed measuring disc is arranged in the through hole.

[0007] The aforementioned technical solution makes the removable mounting base easier and faster to install and remove the hydraulic motor, facilitating subsequent maintenance. Furthermore, the relatively enclosed through-hole effectively protects the speed disc, preventing it from contacting dust and debris, thereby maximizing the speed sensor's detection accuracy. The removable connection between the mounting base and the frame can incorporate vibration-damping materials or devices to further reduce vibration transmission and improve system stability and lifespan.

[0008] Furthermore, a connecting hole is provided on the mounting seat along the radial direction of the speed measuring disc, the connecting hole is communicated with the through hole, and the speed sensor passes through the connecting hole and is arranged toward the speed measuring disc.

[0009] By adopting the above technical solution, the speed sensor is fixed in the radial direction of the speed measuring disc through the connecting hole, which can ensure the precise alignment of the sensor and the speed measuring disc as much as possible, thereby ensuring the stability of the measurement as much as possible.

[0010] Furthermore, the connecting hole is provided with an internal thread, the rotation speed sensor is provided with an external thread, and the rotation speed sensor and the connecting hole are threadedly connected.

[0011] By adopting the above-mentioned technical solution, the speed sensor can be quickly screwed into or out of the connecting hole through a threaded connection. By rotating the speed sensor, its position can be fine-tuned to ensure the precise alignment of the speed sensor and the speed measuring disk, thereby improving the measurement accuracy. The installation and disassembly are relatively convenient. The threaded connection can also provide a relatively stable fixing force, ensuring that the speed sensor can remain stable in a high speed and vibration environment as much as possible, and minimizing the risk of loosening or falling off.

[0012] Furthermore, the mounting seat and the frame are both provided with mounting holes, and the mounting seat and the frame are connected by bolts.

[0013] Through the above technical solution, the mounting base can be quickly fixed to the frame through bolt connection. The installation process is simple and fast, and no complicated tools are required. The bolt connection can provide a relatively stable fixing force, ensuring that the mounting base can remain stable as much as possible in high speed and vibration environments.

[0014] Furthermore, the fan and the hydraulic motor are located on different sides of the frame.

[0015] Through the above technical solution, the separate arrangement of the hydraulic motor and the fan can significantly reduce vibration transmission.

[0016] Furthermore, the fan is fixed to the frame via a flange.

[0017] Through the above technical solution, the flange connection can provide high-strength fixing force, ensuring that the fan can remain stable in high-speed and vibration environments, reducing the risk of loosening or falling off.

[0018] Furthermore, the frame includes a mounting frame and protective frames located on both sides of the mounting frame, the mounting frame and the protective frame form an accommodating space for accommodating the fan, and the fan and the hydraulic motor are installed on the mounting frame.

[0019] Through the above technical solution, the mounting frame and the protective frame can protect the fan, prevent external objects from entering the fan area as much as possible, reduce physical damage to the fan, and prevent operators from accidentally contacting high-speed rotating fan blades as much as possible, thereby improving operational safety.

[0020] Furthermore, the mounting frame and the protective frame are both hollowed out.

[0021] Through the above technical solution, the hollow design can significantly reduce the weight of the mounting frame and the protective frame, and can also promote air circulation and further improve the heat dissipation effect.

[0022] Furthermore, the protective frame and / or the mounting frame is provided with a plurality of fixing holes.

[0023] Through the above technical solution, multiple fixing holes can provide more support points, thereby improving the installation reliability of the hydraulically driven radiator fan device. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0037] like Figures 1 to 5As shown, the present invention provides a hydraulically driven radiator fan device suitable for dissipating heat from a radiator on an agricultural harvester. The device comprises a frame 3, a hydraulic motor 1 mounted on the frame 3, and a fan 4. The output of the hydraulic motor 1 is connected to the input of the fan 4 via a drive shaft 7. A speed disc 8 is fixed to the drive shaft 7, and a speed sensor 5 is mounted on one side of the speed disc 8. The speed sensor 5 is used to measure the speed of the speed disc 8. The speed disc 8 is circumferentially slotted, serving as markings 81.

[0038] By driving the fan 4 through the hydraulic motor 1, the speed of the fan 4 can be flexibly adjusted according to the actual heat dissipation demand, and is no longer restricted by the engine speed. Secondly, by monitoring the speed of the speed measuring disk 8 in real time through the speed sensor 5, the speed of the fan 4 can be accurately controlled and the heat dissipation efficiency can be adjusted according to actual needs. At the same time, the speed sensor 5 calculates the speed by detecting the mark 81, which can provide higher measurement accuracy. Finally, the fan 4 is not strictly restricted by the engine layout. The fan 4 can be more freely arranged in the position that is most conducive to heat dissipation, optimize the airflow path, and improve the overall heat dissipation effect.

[0039] It should be noted that agricultural harvesting machine models may include silage machines, rice and wheat combine harvesters, corn harvesters and small terrace harvesters, etc.

[0040] The fan 4 and the hydraulic motor 1 are located on different sides of the frame 3. The separate arrangement of the hydraulic motor 1 and the fan 4 can significantly reduce vibration transmission.

[0041] It also includes a mounting base 2 for mounting the hydraulic motor 1. The mounting base 2 and the frame 3 are detachably connected. The detachable mounting base 2 makes the installation and removal of the hydraulic motor 1 more convenient and quick, and is convenient for later maintenance.

[0042] Specifically, mounting base 2 and frame 3 are both provided with mounting holes. Bolts connect the two, allowing mounting base 2 to be quickly secured to frame 3. Installation is simple and quick, requiring no complex tools. The bolted connection provides a relatively stable fixing force, ensuring that mounting base 2 remains stable even in high-speed and vibration environments. Fan 4 is secured to frame 3 via flange 6. This flange connection provides a high degree of fixing force, ensuring that fan 4 remains stable even in high-speed and vibration environments, and reducing the risk of loosening or falling off.

[0043] The frame 3 includes a mounting frame 31 and protective frames 32 located on either side of the mounting frame 31. The mounting frame 31 and the protective frames 32 form a receiving space 33 for accommodating the fan 4. The fan 4 and the hydraulic motor 1 are mounted on the mounting frame 31. The mounting frame 31 and the protective frames 32 protect the fan 4, preventing foreign objects from entering the fan 4 area and reducing physical damage to the fan 4. They also prevent operators from accidentally contacting the high-speed rotating fan 4 blades, thereby improving operational safety.

[0044] Furthermore, the mounting frame 31 and the protective frame 32 are both hollowed out. The hollowing design can significantly reduce the weight of the mounting frame 31 and the protective frame 32, and can also promote air circulation, further improving the heat dissipation effect.

[0045] It should be noted that a solid mounting platform 35 is provided at the position of the mounting frame 31 for mounting the fan 4 and the hydraulic motor 1. The mounting platform 35 is provided with a through hole 36 for the transmission shaft 7 to pass through, which increases the structural strength of the mounting frame 31 while facilitating the installation of the fan 4 and the hydraulic motor 1.

[0046] The protective frame 32 is provided with a plurality of fixing holes 34, which can provide more support points and improve the installation reliability of the hydraulically driven radiator fan device. Bolts can be passed through the fixing holes 34 to connect to the external structure.

[0047] Furthermore, the mounting base 2 is provided with a through hole 21 through which the transmission shaft 7 rotates. The through hole 21 is relatively closed, and the speed measuring disc 8 is disposed within the through hole 21, effectively protecting the speed measuring disc 8 from external dust and debris, thereby maximizing the detection accuracy of the speed sensor 5. The transmission shaft 7 is rotatably connected to the mounting base 2 via a bearing 9.

[0048] Mounting base 2 has a connecting hole 22 formed radially along speed measuring disc 8. Connecting hole 22 communicates with through-hole 21. Speed ​​sensor 5 passes through connecting hole 22 and is positioned toward speed measuring disc 8. By securing speed sensor 5 radially along speed measuring disc 8 via connecting hole 22, precise alignment of speed sensor 5 with speed measuring disc 8 is ensured, thereby maximizing measurement stability.

[0049] The connection hole 22 is internally threaded, and the speed sensor 5 is externally threaded. The speed sensor 5 is threadedly connected to the connection hole 22. The speed sensor 5 can be quickly screwed into or out of the connection hole 22. By rotating the speed sensor 5, its position can be fine-tuned to ensure precise alignment between the speed sensor 5 and the speed measuring disk 8, thereby improving measurement accuracy and facilitating installation and removal. The threaded connection also provides a relatively stable fixing force, ensuring that the speed sensor 5 remains stable in high-speed and vibration environments, and minimizing the risk of loosening or falling off.

[0050] It is understandable that in other embodiments, the speed sensor can also be connected and fixed by a snap-fit ​​structure, which makes installation more convenient.

[0051] It is understandable that in other embodiments, the mounting bracket is provided with a plurality of fixing holes to increase the ways of connecting with the external structure.

[0052] In addition to the above-mentioned preferred embodiments, the present invention has other implementation methods. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
