[0002] The smart agriculture science popularization robot is an intelligent device designed specifically for the dissemination of knowledge and promotion of technology in the agricultural field. It integrates cutting-edge technologies from multiple disciplines such as artificial intelligence, robotics, and multimedia technology to meet the learning needs of different users for smart agriculture knowledge. The robot usually has a flexible and movable chassis and is equipped with a variety of functional modules. Its head is often equipped with a high-definition display screen and advanced voice interaction devices to display science popularization videos, charts, and provide clear and fluent voice explanations.

[0003] However, traditional smart agricultural science popularization robots typically have their displays fixedly mounted on the robot body. When in use, these robots often need to provide services to visitors of different ages and heights in open spaces. The fixed displays cannot be adjusted to accommodate the height of visitors. Children or shorter individuals may find it difficult to look at the content at eye level and may have to strain to look up, leading to neck fatigue over time and significantly impacting their visitor experience and knowledge reception. Taller visitors, on the other hand, may have to bend over or lower their heads to view the relatively low display, which is equally inconvenient and affects both the viewing experience and the effectiveness of science education. Therefore, a smart agricultural science popularization robot is proposed to address these issues. Utility Model Content

[0031] 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 protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a smart agricultural science popularization robot, including a shell 1, which is the robot's casing. A support plate 2, capable of moving the shell 1, is located at the bottom of the shell 1. An adjustment mechanism is located on the left side of the shell 1, comprising an adjustment component 3 and a locking component 5. The locking component 5 includes a hollow locking ring 51 that can limit a circular ball 35 using multiple sets of limiting blocks 54. The adjustment component 3 includes a display arm 31 fixedly connected to the front surface of the shell 1 near the left side. The display arm 31 is used for... To support the adjustment component 3, a circular protrusion is fixedly connected to the rearward surface of the left side of the display arm 31. The circular protrusion is rotatably connected to the display screen 33 to provide support. The rear surface of the circular protrusion is rotatably connected to the display screen 33, which can popularize agricultural knowledge and display information. Multiple sets of circular locking balls 35 are slidably connected through the outer wall of the circular protrusion on the left side of the display arm 31. The circular locking balls 35 can be initially positioned by locking into the circular locking groove 34. The inner surfaces of the multiple sets of circular locking balls 35 are all fixedly connected to connecting rods 37 that support the circular locking balls 35.

[0033] Furthermore, the ends of multiple connecting rods 37 away from the circular locking ball 35 are all elastically connected to the display arm 31 via springs 38. The elastic force of the springs 38 can cause the circular locking ball 35 to be squeezed inward and then quickly reset and locked into the corresponding circular locking slot 34. Multiple positioning grooves 36 are provided on the outer wall of the left end of the display arm 31. The positioning grooves 36 provide space for the circular locking ball 35 and the limiting block 54 to move. The outer wall of the circular protrusion on the left side of the display arm 31 is rotatably connected to a limiting ring 32 fixed on the display screen 33 to limit the circular locking slot 34 and the circular locking ball 35. Multiple circular locking slots 34 are evenly provided on the inner wall of the limiting ring 32 to engage with the circular locking ball 35.

[0034] Reference Figure 3 , Figure 5 and Figure 6 The locking component 5 also includes a threaded rod 53, which is threadedly connected to the display arm 31. By rotating the threaded rod 53, the hollow locking ring 51 can be moved toward the limiting ring 32. The threaded rod 53 passes through the front surface of the display arm 31 and is threadedly connected to it. The threaded rod 53 is rotatably connected to the front surface of the hollow locking ring 51. The interior of the circular protrusion is provided with an annular groove 52 that provides space for the hollow locking ring 51 to move. The annular groove 52 passes through the positioning groove 36.

[0035] Reference Figure 3 , Figure 5 and Figure 6 Multiple sets of circular locking balls 35 are slidably connected to the inner wall of the corresponding positioning groove 36. The limiting ring 32 is fixedly connected to the front surface of the display screen 33. Both the circular locking balls 35 and the circular grooves 34 are set to be circular. The circular locking balls 35 are set to be circular and can be squeezed by the circular grooves 34, thereby causing the circular locking balls 35 to move inward and squeeze the spring 38. Multiple sets of circular locking balls 35 and circular grooves 34 are arranged in a ring array with the center point of the circular protrusion as the center. Two sets of adjustment components 3 are provided, and the two sets of adjustment components 3 are symmetrically arranged on the rear surface of the display screen 33 and the housing 1 with the display screen 33 as the axis of symmetry. Adjustment components 3 are provided on both sides of the display screen 33 to increase the stability after the limit is set.

[0036] Reference Figure 4 , Figure 5 and Figure 6The hollow locking ring 51 is slidably connected to the inner wall of the annular groove 52. A limiting block 54 is fixedly connected between the circular locking ball 35 and the connecting rod 37 to limit the circular locking ball 35 so that it cannot move inward. The limiting block 54 slides on the inner wall of the positioning groove 36. A slot is opened on the left side of the hollow locking ring 51 to slide into the connecting rod 37. The slot provides space for the connecting rod 37 to move. The limiting block 54 is engaged on the outer side of the slot on the left side of the hollow locking ring 51. The left side of the hollow locking ring 51 is set as an inward inclined slope. By setting the slope, the circular locking ball 35 can be squeezed during movement, so that the circular locking ball 35 moves outward and is engaged in the corresponding circular slot 34. With the limiting block 54 engaged on the outer surface of the hollow locking ring 51, the circular locking ball 35 can be stably limited in the corresponding circular slot 34, thereby stably limiting the adjusted display screen 33.

[0037] Reference Figure 1 and Figure 2 A lifting assembly 4 is provided between the housing 1 and the support plate 2 to adjust the height of the housing 1. The lifting assembly 4 includes a hydraulic rod 41 and a positioning rod 42. Multiple positioning rods 42 are fixedly connected to the top of the support plate 2, and multiple positioning rods 42 are slidably connected to the housing 1. A guide block 43 is fixedly connected to the right side of the housing 1 to drive the housing 1 to rise and fall. The guide block 43 is fixedly connected to the top of the output end of the hydraulic rod 41. The hydraulic rod 41 provides driving force to drive the guide block 43 to move.

[0038] Working principle: In use, first connect the external power supply and switch to the electrical equipment in this device. When it is necessary to adjust the angle of the display screen 33, rotate the threaded rod 53 outward to drive the hollow locking ring 51 to move outward, releasing the limit of the display screen 33. At this time, manually rotate the display screen 33. Since the display screen 33 is rotatably connected to the display arm 31 through the circular protrusion, it can rotate flexibly. During the rotation, the limiting ring 32 fixed on the front surface of the display screen 33 rotates accordingly. The circular groove 34 on the inner wall of the limiting ring 32 and the circular retaining ball 35 on the outer wall of the circular protrusion on the left side of the display arm 31... Through interaction, the circular locking ball 35, under the pressure of the circular locking groove 34, moves inward through the compression spring 38 via the connecting rod 37. When it rotates to a suitable angle, the circular locking ball 35 will quickly reset under the elastic force of the spring 38 and lock into the corresponding circular locking groove 34, thus achieving the initial positioning of the display screen 33 angle. Multiple sets of circular locking balls 35 and circular locking grooves 34 are arranged in a circular array with the center point of the circular protrusion as the center, which can achieve initial positioning at multiple angles. In addition, the two sets of adjustment components 3 are symmetrically arranged on both sides of the display screen 33, and the multiple displays 33 are supported on both sides, which can enhance stability.

[0039] After initial positioning, to ensure that the display screen 33 will not change its angle due to accidental shaking during use, it needs to be locked. At this time, the threaded rod 53 is rotated in the opposite direction to connect with the display arm 31, causing the threaded rod 53 to move towards the display screen 33. Because the threaded rod 53 is threaded to the display arm 31 and rotatably connected to the front surface of the hollow locking ring 51, rotating the threaded rod 53 will cause the hollow locking ring 51 to move along the annular groove 52 towards the limiting ring 32 and the display screen 33. The left side of the hollow locking ring 51 is set with an inward inclined slope. During the movement, this slope will squeeze the circular locking ball 35, causing the circular locking ball 35 to move outward and fit more tightly into the circular locking groove 34. At the same time, the limiting block 54, which is fixedly connected between the circular locking ball 35 and the connecting rod 37, will be locked on the outside of the hollow locking ring 51 groove, stabilizing and limiting the circular locking ball 35 so that it cannot move. At this time, the display screen 33 with the adjusted angle can be firmly locked, making it convenient for visitors to use stably.

[0040] When the robot's overall height needs to be adjusted to accommodate visitors of different heights, the hydraulic rod 41 is activated. The output end of the hydraulic rod 41 moves up or down. Since the guide block 43 is fixedly connected to the top of the output end of the hydraulic rod 41 and is also fixedly connected to the right side of the housing 1, the extension and retraction of the hydraulic rod 41 will drive the guide block 43, thereby causing the housing 1 to rise or fall. Multiple sets of positioning rods 42 are fixedly connected to the top of the support plate 2 and slidably connected to the housing 1. They play a guiding and stabilizing role, ensuring that the housing 1 remains stable during the lifting and lowering process, avoiding shaking or deviation. By adjusting the extension and retraction length of the output end of the hydraulic rod 41, the robot can reach a suitable height to meet the needs of visitors of different heights to maintain a good line of sight with the display screen 33, further improving adaptability.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
