Description

Technical Field

[0001] This utility model relates to the field of harvesters, specifically an agricultural harvester display terminal. Background Technology

[0002] Combine harvesters are primarily used for harvesting crops, significantly improving harvesting efficiency and reducing the labor intensity for farmers. Different types of combine harvesters are suitable for different crops and harvesting environments, such as grain harvesters, corn harvesters, and rice harvesters. These harvesters are typically equipped with powerful engines, efficient cutting devices, and convenient collection systems to ensure smooth harvesting operations.

[0003] When a harvester is reversing, its long body and limited visibility make it difficult for the driver to accurately judge the environment behind the vehicle. A reversing camera display terminal can provide real-time rearward images, helping the driver better understand the vehicle's dynamics and avoid collisions and scratches.

[0004] Existing harvesters typically operate in sunny weather. During use and observation, it has been found that when the sunlight is too intense, it can cause glare on the surface of the display terminal inside the harvester, which increases the difficulty of observing the display terminal surface.

[0005] Therefore, a display terminal for agricultural harvesters is proposed to address the above problems. Utility Model Content

[0008] Preferably, multiple elastic ropes are fixed to both sides of the elastic fabric; a second upright plate is fixed to the end of one side of the elastic rope; connecting components are provided on both sides of the display; by setting the elastic ropes, the elastic ropes will apply tension to the elastic fabric, so that the elastic fabric will pile up to the outside of the second upright plate when folded, reducing the obstruction effect of the elastic fabric on the display surface when it is stacked.

[0009] Preferably, the connecting component includes hook and loop fasteners; the hook and loop fasteners and the display are fixedly connected; the surface of the hook and loop fasteners has a hook side; the inner wall of the second upright plate has a rough side; when in use, the rough side of the second upright plate can be aligned with the hook side of the hook and loop fasteners, so that the second upright plate will adhere to the surface of the hook and loop fasteners, realizing the device to quickly fix the second upright plate and the hook and loop fasteners. When a large movement of the elastic fabric is required, the second upright plate and the hook and loop fasteners can also be quickly separated by peeling off the second upright plate, reducing the damage to the elastic cord caused by excessive stretching.

[0010] Preferably, the guide rod has multiple scales in the middle; the scales are equidistant; when the screw is rotated to control the guide rod, the guide rod will move along with the scales, and the moving distance of the guide rod can be judged by observing the scales, so that the moving stroke of the connecting plate can be controlled more accurately.

[0011] Preferably, the bottom of the bracket is provided with a release film; the bottom of the bracket may be provided with an adhesive coating, so that when the display is installed, the release film can be peeled off and the display can be quickly adhered to the inside of the vehicle body through the coating on the bottom of the bracket, thereby improving the convenience of the device for installing the display and the bracket.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1 to 5As shown in the embodiment of this utility model, an agricultural harvester display terminal includes a display 1. A vertical plate 12 is fixedly connected to the top of the display 1. A screw 13 is rotatably connected to the middle of the vertical plate 12. A connecting plate 15 is threadedly connected to the middle of the screw 13. Multiple guide rods 14 are fixedly connected to the middle of the connecting plate 15. The guide rods 14 and the vertical plate 12 are through-connected and slidably connected. An elastic cloth 16 is fixedly connected between the connecting plate 15 and the display 1. A bracket 17 is installed in the middle of the display 1. During installation, the operator can connect the display 1 to a reversing camera via a video signal cable. The display 1 can be installed inside the harvester using the bracket 17. After installation, the screen of the display 1 will display the reversing image captured by the camera. Because the harvester operates outdoors, it is susceptible to damage from strong sunlight. In situations where sunlight is insufficient, the content displayed on the surface of monitor 1 may be difficult to observe due to screen glare. This can be addressed by rotating screw 13, which allows connecting plate 15 to slide along it. Guide rod 14 will slide along vertical plate 12 and provide guidance for the movement of connecting plate 15. As connecting plate 15 moves, it will move along with elastic cloth 16 until the elastic cloth 16 can block the light from the screen of monitor 1. At this point, the operator can easily observe the screen of monitor 1. When sunlight is normal, rotating screw 13 can make connecting plate 15 fit tightly against the surface of monitor 1, reducing the shading effect of elastic cloth 16 on the surface of monitor 1. Through the combined action of connecting plate 15 and elastic cloth 16, rotating screw 13 can control the shading state of elastic cloth 16 on monitor 1, preventing reflection of sunlight on the surface of monitor 1 and improving the ease of observation of the surface of monitor 1.

[0026] Please see Figures 1 to 3 As shown, multiple elastic ropes 2 are fixed to both sides of the elastic fabric 16; a second vertical plate 22 is fixed to the end of one side of the elastic rope 2; connecting components are provided on both sides of the display 1; when the screw 13 is rotated to fold the elastic fabric 16 by the connecting plate 15, the elastic rope 2 will be fixed and stretched under the connection of the second vertical plate 22 and the connecting components. Because of the elasticity of the elastic rope 2, the elastic fabric 16 will fold outwards from the connecting plate 15 under the elastic force of the elastic rope 2 when folding, reducing the amount of elastic fabric 16 stacked on the inner side of the connecting plate 15. When the connecting plate 15 with the elastic fabric 16 covers the display 1, the elastic rope 2 will also pull on the surface of the elastic fabric 16 under its own elastic force, increasing the tension on the surface of the elastic fabric 16 and ensuring that the surface of the elastic fabric 16 can be kept taut. By setting the elastic rope 2, the elastic rope 2 will apply a pulling force to the elastic fabric 16, causing the elastic fabric 16 to pile up outwards from the connecting plate 15 when folded, reducing the covering effect of the stacked elastic fabric 16 on the surface of the display 1.

[0027] Please see Figure 3 and Figure 5 As shown, the connecting component includes a hook and loop fastener 3; the hook and loop fastener 3 and the display 1 are fixedly connected; the surface of the hook and loop fastener 3 is provided with a hook surface; the inner wall of the second upright plate 22 is provided with a rough surface; when the device is in use, the rough surface of the second upright plate 22 can be aligned with the hook surface of the hook and loop fastener 3, so that the second upright plate 22 will adhere to the surface of the hook and loop fastener 3, realizing the device to quickly fix the second upright plate 22 and the hook and loop fastener 3. When it is necessary to move the elastic fabric 16 significantly, the second upright plate 22 and the hook and loop fastener 3 can also be quickly separated by peeling off the second upright plate 22, reducing the damage to the elastic rope 2 caused by excessive stretching.

[0028] Please see Figure 4 As shown, the guide rod 14 has multiple scales 4 in the middle; the scales 4 are set at equal intervals; when the screw 13 is rotated to control the guide rod 14, the guide rod 14 will move along with the scales 4. The moving distance of the guide rod 14 can be judged by observing the scales 4, so that the moving stroke of the connecting plate 15 can be controlled more accurately.

[0029] Please see Figure 2 and Figure 5 As shown, the bottom of the bracket 17 is provided with a release film 5; the bottom of the bracket 17 may be provided with an adhesive coating, so that when the display 1 is installed, the release film 5 can be peeled off and the display 1 can be quickly adhered to the inside of the vehicle body through the coating at the bottom of the bracket 17, thereby improving the convenience of the device for installing the display 1 and the bracket 17.

[0030] Please see Figure 2 and Figure 5 As shown, a tab 6 is fixed to the surface of the release film 5; the tab 6 is arc-shaped; by providing a tab 6 on one side of the release film 5, the release film 5 can be quickly peeled off by pulling the tab 6 when it is peeled off, which improves the convenience of peeling the release film 5 from the bottom of the support 17.

[0031] Working principle: During installation, the operator can connect monitor 1 to the reversing camera via a video signal cable. During connection, monitor 1 can be installed inside the harvester using bracket 17. After installation, the screen of monitor 1 will display the reversing image captured by the camera. Because the harvester operates outdoors, the content displayed on the monitor 1 may be difficult to see due to screen glare when exposed to strong sunlight. This can be addressed by rotating screw 13, which allows connecting plate 15 to slide along it. Guide rod 14 will slide along vertical plate 12, providing guidance for the movement of connecting plate 15. When the connecting plate 15 moves, it moves along with the elastic cloth 16 until the elastic cloth 16 can block the light from the screen of the monitor 1. At this time, the operator can easily observe the screen of the monitor 1. When the sunlight is normal, the connecting plate 15 can be pressed tightly against the surface of the monitor 1 by rotating the screw 13, reducing the blocking effect of the elastic cloth 16 on the surface of the monitor 1. When the connecting plate 15 is folded by rotating the screw 13, the elastic rope 2 will be fixed and stretched under the connection of the upright plate 22 and the connecting assembly. Because of the elasticity of the elastic rope 2, the elastic cloth 16 will be stretched by the elastic rope 2 when folded. Under the action of elasticity, the connecting plate 15 is folded outward, reducing the amount of elastic cloth 16 stacked on the inner side of the connecting plate 15. When the connecting plate 15, along with the elastic cloth 16, covers the display 1, the elastic rope 2 will also pull on the surface of the elastic cloth 16 under its own elasticity, increasing the tension on the surface of the elastic cloth 16 and ensuring that the surface of the elastic cloth 16 remains taut. When using the device, the rough side of the surface of the second upright plate 22 can be aligned with the hook side of the hook and loop fastener 3, so that the second upright plate 22 will adhere to the surface of the hook and loop fastener 3, achieving quick fixation of the second upright plate 22 and the hook and loop fastener 3. When a large movement of the elastic cloth 16 is required, it can also be adjusted. The vertical plate 22 and the Velcro 3 can be quickly separated by peeling off the vertical plate 22; when the screw 13 is rotated to control the guide rod 14, the guide rod 14 will move along with the scale 4. The movement distance of the guide rod 14 can be judged by observing the scale 4, so that the movement stroke of the connecting plate 15 can be controlled more accurately; the bottom of the bracket 17 can be provided with an adhesive coating, so that when the display 1 is installed, the release film 5 can be peeled off and quickly adhered to the inside of the vehicle body through the coating at the bottom of the bracket 17; by providing a protrusion 6 on one side of the release film 5, the release film 5 can be quickly peeled off by pulling the protrusion 6 when it is peeled off.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
