[0019] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] The fan device and agricultural machinery of this application are described below with reference to the accompanying drawings.

[0021] The descriptions of directions such as "up", "down", "front", "back", "left", and "right" in this application are as follows: Figure 1 The orientation shown is a baseline and represents the operator's position while seated in the driver's seat; it is for illustrative purposes only. Figure 1 The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0022] like Figures 1 to 4 As shown, this application provides a fan device, wherein the fan device includes an armrest 10 and a rotating fan assembly. The armrest 10 is located on the side of the driver's seat and can be climbed onto the driver's seat. The rotating fan assembly includes a rotating bracket 20 located on the outside of the driver's seat and a fan 30 mounted on the rotating bracket 20. One end of the rotating bracket 20 is rotatably mounted on the armrest 10 to adjust the angle of the fan 30 facing the driver's seat 60.

[0023] The handrail 10 is located on the side of the driver's seat, allowing the operator to climb onto the driver's seat more easily. The rotating bracket 20 is located outside the driver's seat, effectively avoiding encroachment on the interior space, thus ensuring the operator's working space and comfort. It also facilitates the maintenance and repair of the rotating fan assembly, providing sufficient space to adjust the fan's angle towards the driver's seat 60 without entering the driver's seat, improving maintenance efficiency and ease of use. A fan 30 is mounted on the rotating bracket 20, with one end rotatably mounted on the handrail 10, allowing adjustment of the fan 30's angle towards the driver's seat 60. This adjustment can be tailored to the operator's needs, increasing the flexibility of the fan system and helping to alleviate the effects of hot weather on the operator, providing cooling relief and improving work efficiency.

[0024] In the embodiments of this application, please refer to Figure 2 The rotating bracket 20 includes a first rotating arm 21 and a second rotating arm 22 that are connected to the fan 30 and spaced apart on both sides of the fan 30; the handrail 10 includes a fixed frame 11 and a first mounting arm 12 and a second mounting arm 13 that are spaced apart on the fixed frame 11. The fixed frame 11 is located on the side of the driver's seat and can be climbed onto the driver's seat. The first rotating arm 21 and the second rotating arm 22 are rotatably connected to the first mounting arm 12 and the second mounting arm 13 respectively.

[0025] Both the first rotating arm 21 and the second rotating arm 22 are connected to the fan 30 and are spaced apart on the upper and lower sides of the fan 30. This connection between the first rotating arm 21 and the second rotating arm 22 and the fan 30 ensures a stable and reliable connection between the rotating bracket 20 and the fan 30. The mounting frame 11 is located on the side of the driver's seat and allows the operator to climb onto the driver's seat. The first mounting arm 12 and the second mounting arm 13 extend along the width direction of the driver's seat, which is from the driver's left to right. The first mounting arm 12 and the second mounting arm 13 are spaced apart on the mounting frame 11 in the vertical direction. The first rotating arm 21 is rotatably connected to the first mounting arm 12, and the second rotating arm 22 is rotatably connected to the second mounting arm 13, enabling the rotating bracket 20 to rotate stably and reliably relative to the armrest frame 10, making the angle adjustment of the fan 30 more convenient.

[0026] In the embodiments of this application, please refer to Figure 1 and Figure 2The first mounting arm 12 and the second mounting arm 13 both include a mounting rod 121 and a mounting seat 122 connected to each other. The mounting rod 121 is connected to the fixing frame 11. The end of the mounting seat 122 away from the mounting rod 121 forms a rotation space 123 for inserting the rotating arm. The rotating bracket 20 also includes a fastener 23 and a locking member 24. The rotating arm and the mounting seat 122 of the corresponding mounting arm are rotatably connected by the fastener 23 and can be locked by the locking member 24.

[0027] Mounting rod 121 extends along the width of the driver's seat and connects to the inner side of mounting bracket 11 to achieve the installation and fixation of the first mounting arm 12 and the second mounting arm 13. A rotation space 123 is formed at the end of mounting base 122 away from mounting rod 121. The rotation space 123 is used for inserting the first rotating arm 21 and the second rotating arm 22, such as... Figure 1 As shown, the rotation space 123 is arranged in a "U" shape. The first rotating arm 21 and the second rotating arm 22 can rotate horizontally within the rotation space 123. The rotating arm and the corresponding mounting base 122 of the mounting arm are rotatably connected by fasteners 23, wherein the fasteners 23 can be bolts. The bolts pass through the mounting base 122 and the rotating arm in sequence, and the bolts extend in the vertical direction, allowing the rotating arm to rotate around the bolts. Furthermore, the rotating arm and the corresponding mounting base 122 can be locked by locking member 24, wherein the locking member 24 can be a nut. The thread of the bolt extends out of one end of the mounting base 122 and is threadedly connected to the nut. After the rotating bracket 20 rotates to a preset angle, the nut can be tightened to abut against the mounting base 122 to fix the rotating bracket 20, thereby keeping the rotating bracket 20 and the fan 30 at the preset angle.

[0028] In other embodiments, the rotating arm and the mounting base 122 can be rotatably connected by a hinge, pin, shaft, gear or other structure.

[0029] In the embodiments of this application, please refer to Figure 1 and Figure 3 The fixed frame 11 includes a first handrail 111, a second handrail 112, and a third handrail 113 connected between the first handrail 111 and the second handrail 112. The first handrail 111 and the second handrail 112 are spaced apart along the length of the driver's seat and both extend along the height of the driver's seat. The second handrail 112 is located on the side of the first handrail 111 away from the driver's seat, and the first rotating arm 21 and the second rotating arm 22 are spaced apart on the second handrail 112.

[0030] Both the first armrest 111 and the second armrest 112 extend along the height direction of the driver's seat, i.e., in the vertical direction. The first armrest 111 and the second armrest 112 are spaced apart along the length direction of the driver's seat, which refers to the vehicle's driving direction, i.e., in the front-to-back direction. The second armrest 112 is located on the side of the first armrest 111 furthest from the driver's seat, i.e., in front of the first armrest 111. Furthermore, the first rotating arm 21 and the second rotating arm 22 are spaced apart along the vertical direction on the second armrest 112, so that the rotating bracket 20 is located outside the driver's seat and facilitates the rotation of the rotating bracket 20 so that the fan 30 can better face the driver's seat 60.

[0031] like Figure 3 As shown, taking the driver's seat of a rice transplanter as an example, an access passage is formed between the driver's seat 60 and the handrail 10, and there are access openings on both the left and right sides of the driver's seat 60. The operator can enter the driver's seat from the front of the driver's seat 60 by climbing the second handrail 112 and the third handrail 113; or, the operator can enter the driver's seat from the right side of the driver's seat 60 by climbing the first handrail 111. The first handrail 111, the second handrail 112, and the third handrail 113 work together to facilitate the operator's access to the driver's seat.

[0032] Understandable Figure 3 The central fan device is located on the right side of the driver's seat 60. In another embodiment, fan devices can be installed on both the left and right sides of the driver's seat 60 to increase the air circulation speed and improve the cooling effect.

[0033] For example, the control switch 33 of the fan 30 can be set on the first handrail 111 to facilitate the operator to control the switch or wind speed of the fan 30.

[0034] In the embodiments of this application, please refer to Figure 1 The first mounting arm 12 and the second mounting arm 13 are located on the side of the second handrail 112 close to the first handrail 111, and both the first mounting arm 12 and the second mounting arm 13 are detachably connected to the second handrail 112.

[0035] The first mounting arm 12 and the second mounting arm 13 are located on the side of the second handrail 112 close to the first handrail 111. This reduces the size of the fan device and avoids interference with the operator's work by the first mounting arm 12 and the second mounting arm 13, making the fan device more convenient to use.

[0036] Both the first mounting arm 12 and the second mounting arm 13 are detachably connected to the second handrail 112, facilitating replacement of the first mounting arms 12 and 13 after wear. Simultaneously, the detachable connection allows adjustment of the vertical position of the first mounting arms 12 and 13, making their use more flexible and convenient. Specifically, the first mounting arms 12 and 13 can be detachably connected to the second handrail 112 via bolts. Bolts are readily available and easy to install, and the threaded connection provides self-locking, ensuring stable installation of the first mounting arms 12 and 13 on the second handrail 112.

[0037] In the embodiments of this application, please refer to Figure 1 The rotating bracket 20 also includes a gripping rod 25 connected between the first rotating arm 21 and the second rotating arm 22, the gripping rod 25 extending out of the fan 30.

[0038] The grip lever 25 extends vertically and connects between the first rotating arm 21 and the second rotating arm 22. The grip lever 25 extends beyond the fan 30. The grip lever 25 makes the structure of the rotating bracket 20 more stable and reliable. Furthermore, the operator can grip the grip lever 25 to adjust the angle of the fan 30, making angle adjustment more convenient.

[0039] In the embodiments of this application, please refer to Figure 1 The fan device also includes a fixing hook 40, one end of which is connected to the rotating bracket 20, and the other end of which is detachably connected to the handrail 10 and the connection position is adjustable.

[0040] The fixing hook 40 is detachably connected to the armrest bracket 10. When it is necessary to adjust the angle of the fan 30 facing the driver's seat 60, the fixing hook 40 can be detached from the armrest bracket 10, allowing the rotating bracket 20 and the fan 30 to rotate. After the fan 30 rotates to the preset angle, the rotating bracket 20 and the fan 30 can be fixed by the fixing hook 40, which provides a fixing and protection function. Furthermore, the connection position between the fixing hook 40 and the armrest bracket 10 is adjustable, allowing the fixing hook 40 to fix the rotating bracket 20 and the fan 30 at multiple angles, making the use of the fixing hook 40 more flexible and convenient.

[0041] In the embodiments of this application, please refer to Figure 1 The fixing hook 40 is movably connected to the rotating bracket 20. The handrail frame 10 has at least two spaced fixing holes 14 for the fixing hook 40 to be inserted.

[0042] At least two fixing holes 14 are spaced apart in the vertical direction. The fixing hook 40 is movably connected to the rotating bracket 20, so that the fixing hook 40 can rotate relative to the rotating bracket 20. The fixing hook 40 can be inserted into the fixing hole 14 for fixation. By inserting it into different fixing holes 14, the connection position between the fixing hook 40 and the handrail 10 can be adjusted, so that the fixing hook 40 can fix the rotating bracket 20 and the fan 30 at different angles.

[0043] In the embodiments of this application, please refer to Figure 1 The fixing hook 40 passes through the handrail frame 10 and extends out of the handrail frame 10. The part of the fixing hook 40 extending out of the handrail frame 10 is threadedly connected to the locking seat 50.

[0044] One end of the fixing hook 40 is connected to the rotating bracket 20, and the other end of the fixing hook 40 passes through the handrail frame 10 and extends out of the handrail frame 10. The locking seat 50 is threadedly connected to the part of the fixing hook 40 that extends out of the handrail frame 10. By adjusting the position of the locking seat 50, the length of the fixing hook 40 extending out of the handrail frame 10 can be adjusted so that the connection position between the fixing hook 40 and the handrail frame 10 is adjustable, so that the fixing hook 40 can fix the rotating bracket 20 and the fan 30 at different angles.

[0045] Specifically, such as Figure 1 As shown, the longer the fixed hook 40 extends out of the handrail 10, the closer the fan 30 is to the handrail 10, and the smaller the angle between the fan 30 and the handrail 10; the shorter the fixed hook 40 extends out of the handrail 10, the farther the fan 30 is from the handrail 10, and the larger the angle between the fan 30 and the handrail 10.

[0046] In the embodiments of this application, please refer to Figure 4 The fan 30 includes a main body 31 and a protective plate 32 connected to each other. The protective plate 32 is disposed on the air inlet surface of the main body 31. The protective plate 32 is detachably connected to the rotating bracket 20, and multiple air inlet holes 321 are provided on the protective plate 32.

[0047] The main body 31 is connected to the protective plate 32, which is located on the air inlet side of the main body 31. The protective plate 32 has multiple evenly spaced air inlet holes 321, allowing air to enter the main body 31. The protective plate 32 prevents foreign objects (such as stones or branches from field operations) from entering the fan 30 and damaging the fan blades, thus extending the fan 30's service life and protecting the operator's safety. The protective plate 32 is detachably connected to the rotating bracket 20, facilitating maintenance and replacement of both the fan 30 and the rotating bracket 20 after wear, making their use more flexible and convenient.

[0048] Specifically, the protective plate 32 and the rotating bracket 20 can be detachably connected by bolts, clips, rivets or other structures.
