[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0028] Reference Figures 1-4 The present invention provides an agricultural harvesting machine, which includes a carrying chamber 1, which is mounted on a mobile device. A loading chamber 2 is detachably mounted on the top of the carrying chamber 1. In application, the carrying chamber 2 and the loading chamber 1 are detachably connected to facilitate the replacement or cleaning of the container.
[0029] A rotating base 3 is symmetrically arranged on the bearing bin 1. An adjusting arm 4 is hinged on the rotating base 3. An end effector 5 is installed at the end of the adjusting arm 4 away from the rotating base 3 through a hinge seat. In application, the hinge structure between the rotating base 3 and the adjusting arm 4 enables multi-degree-of-freedom movement, adapting to complex farmland environments. At the same time, the end effector 5, installed through the hinge seat, can adjust the gripping angle and expand the harvesting range.
[0030] Reference Figure 1 and Figure 2 The cavity at the top of the bearing chamber 1 is adapted to the outer surface of the loading chamber 2. The loading chamber 2 has two sets of convex plates 201 that are integrally formed and symmetrically arranged. The two sets of convex plates 201 rest on the top of the bearing chamber 1 and extend out of the bearing chamber 1 to form a loading and unloading flange. In application, the design of the convex plates 201 and the loading and unloading flange simplifies the disassembly and assembly process of the loading chamber 2, reduces maintenance time costs, and improves the continuity of operation.
[0031] Reference Figure 1 and Figure 2 The rotating base 3 is driven by a drive motor and can drive the adjusting arm 4 to rotate horizontally. In application, the drive motor controls the horizontal rotation of the rotating base 3 to expand the horizontal working range of the harvesting robot arm, reduce the frequency of chassis movement, and improve efficiency.
[0032] Reference Figure 1 and Figure 2 The adjusting arm 4 is a multi-section angle-adjustable structure, and the angle adjustment is controlled by a stepper motor. In application, the multi-section angle-adjustable arm 4, together with the stepper motor, can flexibly extend and retract in the vertical direction and accurately position the fruit (especially suitable for crops with varying heights).
[0033] Reference Figure 1 , Figure 3 as well as Figure 4 The end effector 5 includes an assembly frame 501, which is mounted on the adjusting arm 4 via a hinged seat. A servo motor 502 is mounted on the assembly frame 501, and a lead screw 503 is vertically and rotatably mounted on the assembly frame 501. The output shaft of the servo motor 502 is connected to one end of the lead screw 503. A grid-shaped moving frame 505 is threadedly connected to the outer surface of the lead screw 503. A bionic claw 506 is hingedly mounted on the grid-shaped moving frame 505. In application, the lead screw 503 drives and controls the grid-shaped moving frame 505, which enables the smooth opening and closing of the bionic claw 506 and avoids rigid impact.
[0034] Reference Figure 3 and Figure 4 The bionic claw 506 has a claw head 5061 at its end. The surface of the claw head 5061 is covered with a flexible material, and the inner side is distributed with raised textures 5062 to increase gripping friction. In application, the claw head 5061 is covered with a flexible material and designed with raised textures 5062 to increase friction and buffer pressure, reducing the risk of damage to the skin of fragile fruits such as strawberries and tomatoes.
[0035] Reference Figure 3 and Figure 4 The end of the lead screw 503 away from the servo motor 502 is provided with a stop cap 504 for limiting the movement and preventing the grid moving frame 505 from coming off. In application, the stop cap 504 prevents it from coming off to ensure gripping stability.
[0036] Reference Figure 1 and Figure 2 The mobile device is a wheeled or tracked agricultural robot chassis. The carrying compartment 1 is fixed to the chassis support by bolts. In application, it is compatible with wheeled / tracked chassis and can be quickly installed by bolt fixing to adapt to different farm terrains and robot platforms.
[0037] The working principle of this utility model is as follows: By assembling the loading bin 2 onto the carrying bin 1 and moving it to the target crop area, the rotating base 3 rotates horizontally, and the multi-section adjusting arm 4 adjusts the pitch angle so that the end effector 5 is aligned with the fruit. The robotic arm moves to a position above the fruit and pauses. Then, the servo motor 502 is started. At this time, the output shaft of the servo motor 502 drives the lead screw 503 to rotate. The lead screw 503 pushes the grid moving frame 505 to move, and the bionic claw 506 opens. At the same time, the claw head 5061 wraps around the fruit, and the raised texture 5062 increases the adhesion. After the bionic claw 506 closes, the lead screw 503 retracts in the opposite direction, lifting the fruit. The robotic arm then moves the fruit above the loading bin 2, and the bionic claw 506 opens to release the fruit. The above process is repeated until the loading bin 2 is full. Once the loading bin 2 is full, the loading bin 2 can be disassembled to transfer the fruit, and the empty bin can be replaced to continue the operation.
[0038] This invention provides a type of agricultural harvesting machinery. By employing a flexible bionic claw 506, raised texture 5062 to increase friction, and a lead screw 503 for precise control, it can effectively solve the problem of fruit damage caused by traditional rigid claws. It is especially suitable for high-value and fragile crops, reduces harvesting loss rate, and can significantly improve gripping safety and adaptability.
[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
