Description

Technical Field

[0001] This utility model belongs to the technical field of farmland operation platforms, specifically relating to a liftable farmland operation platform for agricultural robots. Background Technology

[0002] Farmland operation platforms play a key role in modern agriculture, covering scenarios such as orchard operations and plant protection monitoring, improving efficiency and safety.

[0003] To ensure the growth of some fruits and vegetables in farmland, topping is necessary to remove apical dominance. However, some fruits and vegetables have tall tops, making it difficult for pruning workers to perform the topping operation. In such cases, a lifting farmland operation platform is needed for assistance. Since the tops of some fruits and vegetables are located inwards, it is difficult for pruning workers standing on the farmland operation platform to perform the pruning operation. The pruning and topping coverage area is small, and the position of the agricultural robot needs to be adjusted repeatedly, which is very inconvenient.

[0004] Therefore, a liftable farmland operation platform for agricultural robots is proposed. Summary of the Invention

[0005] This utility model provides a liftable farmland operation platform for agricultural robots, the purpose of which is to solve the problems mentioned above.

[0006] This utility model provides a liftable farmland operation platform for agricultural robots, including a support frame; a gear located at the center of the bottom of the support frame, the gear being driven by a servo motor located inside the support frame; a movable frame sliding on the inner wall of the support frame; a toothed plate one located on the inner wall of one side of the movable frame near the gear; a movable plate sliding on the top of the support frame; a toothed plate two located at the bottom of the movable plate near the gear; a horizontal plate located on the inner wall of the movable frame; a three-phase motor fixed to the center of the outer wall of one side of the horizontal plate by bolts; a ball screw fixed to the output end of the three-phase motor; a counterweight fixed to the nut seat on the ball screw by screws; a guardrail located on the top of the movable plate; a base located below the support frame; a pressure sensor located between the support frame and the base; and a guide column located at the bottom of the support frame.

[0007] Furthermore, a hydraulic cylinder is provided at the center of the top of the base located below the base platform, and the output end of the hydraulic cylinder is fixedly connected to the center of the bottom of the base platform.

[0008] Furthermore, both the first toothed plate and the second toothed plate are connected to the gear through gear teeth meshing;

[0009] By adopting the above technical solution, power transmission is achieved through meshing connection. When the gear rotates, the gear pulls the first gear plate and the second gear plate to move in opposite directions, thereby causing the moving frame and the moving plate to move in opposite directions.

[0010] Furthermore, the bottom of the bracket is provided with a through groove for the counterweight to move horizontally;

[0011] By adopting the above technical solution, the through groove provides space for the movement of the counterweight, thereby adjusting the relative position of the counterweight and facilitating the force balance of the base.

[0012] Furthermore, the counterweight has an L-shaped cross-section in the vertical direction and a T-shaped cross-section in the horizontal direction.

[0013] By adopting the above technical solution, the shape and structure of the counterweight not only ensures that the counterweight is not affected by the support frame when moving horizontally, facilitating smooth horizontal movement of the counterweight, but also provides a limit for the horizontal movement of the counterweight, so that the moving frame provides support for the counterweight and ensures stable movement of the counterweight.

[0014] Furthermore, the guide post passes through the base.

[0015] By adopting the above technical solution, the guide column that penetrates the base can provide guidance for the lifting and lowering of the support frame.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes a movable frame and a movable plate that move in opposite directions on a support frame. This allows the pruning worker, standing on the movable plate, to move towards the inside of the fruit and vegetable field, facilitating access to the tops of the fruits and vegetables for topping operations. This increases the pruning range, improves efficiency, and enhances ease of operation. The specially structured counterweight not only ensures that the horizontal movement is unaffected by the support frame but also provides limiting support for the horizontal movement of the counterweight. Furthermore, the counterweight balances the pressure on the pruning worker when standing, preventing the agricultural work platform from tilting. This effectively protects the connection between the hydraulic cylinder output end and the base, ensuring the overall structural integrity and extending service life.

The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Reference Figure 1-5 This utility model embodiment proposes a liftable farmland operation platform for agricultural robots, including a support frame 1. A gear 2 is rotatably connected at the center of the bottom of the support frame 1, and a servo motor that drives the gear 2 to rotate is provided inside the support frame 1. The output end of the servo motor is fixedly connected to the gear 2.

[0028] A movable frame 3 is slidably connected to the inner wall of the support frame 1. A toothed plate 4 is provided on one inner wall of the movable frame 3. A movable plate 5 is slidably connected to the top of the support frame 1. A toothed plate 6 is provided at the bottom of the movable plate 5 near the inner side of the support frame 1. Both toothed plates 4 and 6 are meshed with gear 2 through gear teeth. Power transmission is achieved through meshing. When gear 2 rotates, gear 2 pulls toothed plates 4 and 6 to move in opposite directions, thereby causing the movable frame 3 and movable plate 5 to move in opposite directions. A horizontal plate 7 is provided on one inner wall of the movable frame 3 near the toothed plate 4. A three-phase motor 8 is provided at the center of the outer wall of one side of the horizontal plate 7. A ball bearing is fixedly connected to the output end of the three-phase motor 8. The ball screw 9 and the nut seat on the ball screw 9 are fixedly connected to the counterweight 10 by screws. The bottom of the support frame 1 is provided with a through groove for the counterweight 10 to move horizontally. The through groove provides space for the movement of the counterweight 10, thereby adjusting the relative position of the counterweight 10 and facilitating the force balance of the base 12. The counterweight 10 has an L-shaped cross-section in the vertical direction and a T-shaped cross-section in the horizontal direction. Through the shape and structure of the counterweight 10, not only is the counterweight 10 unaffected by the support frame 1 when moving horizontally, facilitating the smooth horizontal movement of the counterweight 10, but it also provides a limit for the horizontal movement of the counterweight 10, so that the moving frame 3 provides support for the counterweight 10 and ensures the stability of the movement of the counterweight 10.

[0029] A guardrail 11 is provided on the top of the movable plate 5. A base 12 is provided below the support frame 1. A pressure sensor 14 is provided between the top of the base 12 and the bottom of the support frame 1. A guide column 13 is provided at the bottom of the support frame 1. The guide column 13 passes through the base 12 and can provide guidance for the lifting and lowering of the support frame 1. A base 15 is provided below the base 12. A hydraulic cylinder 16 is provided at the center of the top of the base 15. The output end of the hydraulic cylinder 16 is fixedly connected to the center of the bottom of the base 12. The base 15 is installed on the agricultural robot, and the movement of the farmland operation platform is realized by the walking ability of the agricultural robot itself.

[0030] The specific implementation method is as follows: When pruning the tops of fruits and vegetables planted in the farmland, the pruning personnel enter the guardrail 11 and stand on the movable plate 5. The agricultural robot is controlled to carry the farmland operation platform to the required position in the farmland. The hydraulic cylinder 16 is controlled to drive the base 12 to move upward through the output end on one side. During the upward movement of the base 12, the support frame 1 rises synchronously, thereby allowing the pruning worker to rise to a position where the tops of the fruits and vegetables can be pruned.

[0031] To increase the pruning range of fruits and vegetables, the gear 2 is controlled to rotate. Through meshing, the gear 2 pulls the toothed plate 4 and the toothed plate 6 to move. The toothed plate 4 and the toothed plate 6 move in opposite directions. Under the sliding guide, the moving frame 3 and the moving plate 5 move in opposite directions. The pruning worker standing on the moving plate 5 moves closer to the top of the fruits and vegetables, thus increasing the pruning range.

[0032] To maintain the overall balance of the farmland operation platform, when the moving plate 5 and the pruning worker move to one side, the pressure values ​​detected by the multiple pressure sensors 14 on the top of the base 12 differ. At this time, the control three-phase motor 8 drives the ball screw 9 to rotate through its output end on one side. The counterweight 10 on the ball screw 9 moves linearly and moves away from the pruning worker. The counterweight 10 balances the pressure when the pruning worker is standing, preventing the farmland operation platform from tilting and effectively protecting the connection between the output end of the hydraulic cylinder 16 and the base 12.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 claims.
