[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a blind spot monitoring device for agricultural machinery vehicles, including a mounting box 1 and a monitoring base 2. The back of the mounting box 1 is provided with a mounting plate. When in use, the mounting plate is installed on the frame of the agricultural machinery in the blind spot position by screws. The monitoring base 2 is provided with a camera 21 and a lamp 22 located on one side of the camera 21. The camera 21 is selected as a model with wide-angle image capture function. The lamp 22 is used for image capture illumination, which is convenient for nighttime use.

[0022] A window 11 is provided on one side of the mounting box 1. A rotating post 3 is provided inside the mounting box 1, which separates the window 11 from the inner cavity of the mounting box 1, meaning that the inner cavity of the mounting box 1 is in a nearly closed state. In a preferred embodiment, an integral arc-shaped protrusion 15 is fixedly provided on the front side of the mounting box 1, and the window 11 is opened in the middle of the arc-shaped protrusion 15. A sealing gasket 6 is adhered to the inner peripheral wall of the arc-shaped protrusion 15 and fits against the outer peripheral wall of the rotating post 3. The setting of the sealing gasket 6 ensures that the window 11 and the inner cavity of the mounting box 1 are blocked. The outer peripheral wall of the rotating column 3 is provided with a positioning plane 31. When the rotating column 3 rotates, the positioning plane 31 will move to a position opposite to the window 11. The monitoring seat 2 is fixedly set on the positioning plane 31. Thus, when the rotating column 3 is rotated to the point where the camera 21 and the lighting lamp 22 are opposite to the window 11, the camera 21 can capture images of the blind area. When the camera 21 and the lighting lamp 22 are located inside the mounting box 1, the camera 21 and the lighting lamp 22 are in a hidden and protected state.

[0023] Furthermore, support shafts 32 are fixedly connected to both ends of the rotating column 3, and a support plate 12 that is rotatably connected to the support shafts 32 is fixedly connected to the rear side inside the mounting box 1. A control motor 7 is fixedly connected to one side inside the mounting box 1. The output shaft of the control motor 7 is fixedly connected to one end of one of the support shafts 32, and the control motor 7 provides driving force to the rotation of the rotating column 3.

[0024] In this technical solution, a rotating shaft 4 is provided inside the mounting box 1. When in use, the rotating shaft 4 is located below the rotating column 3. A cleaning roller 5 for cleaning the lens of the camera 21 and the lampshade of the lighting lamp 22 is sleeved on the rotating shaft 4. That is to say, when the camera 21 and the lighting lamp 22 are located inside the mounting box 1, the cleaning roller 5 will be in contact with the lens of the camera 21 and the lampshade of the lighting lamp 22. At this time, controlling the rotation of the rotating shaft 4 can simultaneously clean the camera 21 and the lighting lamp 22, and can promptly remove the dust accumulated on the camera 21 and the lighting lamp 22, so that the camera 21 and the lighting lamp 22 can be used normally.

[0025] Furthermore, the sweeping roller 5 includes a central shaft 51, a central sweeping wheel 52, and a side sweeping wheel 53. The central sweeping wheel 52 and the side sweeping wheel 53 are fixedly sleeved on the central shaft 51. There are two side sweeping wheels 53, which are located on both sides of the central sweeping wheel 52. The central sweeping wheel 52 is used to clean the lens of the camera 21, and the side sweeping wheel 53 is used to clean the lampshade of the lighting lamp 22. A sweeping motor 8 is fixedly connected to one side inside the mounting box 1. The output shaft of the sweeping motor 8 is fixedly connected to one end of the central shaft 51. The sweeping motor 8 provides driving force to the rotation of the central shaft 51. The outer periphery of the side sweeping wheel 53 and the central sweeping wheel 52 are both glued with evenly arranged strips of cloth or wool.

[0026] In this embodiment, the rotating column 3 is a hollow structure and one end of it has a wire hole 33 that connects to the inner cavity. The positioning plane 31 has a wire hole 2 that connects to the inner cavity. This arrangement facilitates the introduction of the wiring harness connected to the camera 21 and the lighting lamp 22 on the monitoring seat 2 into the mounting box 1. When in use, a control adapter that is electrically connected to the camera 21 and the lighting lamp 22 can be installed in the mounting box 1, and then the control adapter is electrically connected to the touch screen display in the cab.

[0027] In this embodiment, a duct 13 is fixedly connected to the top of the mounting box 1. A fan 131 is installed inside the duct 13. An exhaust pipe 14 is installed at the bottom of the mounting box 1. When in use, a dust filter can be installed inside the duct 13, and a rain cover (not shown in the figure) can be installed on top of the duct 13. After the fan 131 is started, it can discharge the dust inside the mounting box 1, which has the advantage of cleaning the dust generated.

[0028] Working principle: Before use, a controller electrically connected to the fan 131, sweeping motor 8, and control motor 7 is installed in the mounting box 1. This controller is then connected to the touchscreen display via a wiring harness to achieve remote control of the monitoring device. During use, continuous operation of the agricultural machinery in a dusty environment causes the lens of camera 21 to become covered in dust. At this time, the control column 3 rotates, causing camera 21 to enter the mounting box 1. Then, the sweeping motor 8 is started, and the side sweeping wheel 53 rotates to clean the lens of camera 21. After cleaning, the control column 3 resets, and camera 21 can continue to be used. It should be noted that the cleaning time is only a few seconds, so it will not affect the normal use of camera 21.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
