In addition, by setting the recognition device at the bottom of the robot, the target to be operated (plants or weeds) in the operation area is identified. After the target to be operated is identified, the operating mechanism is controlled to operate the target to be operated.

[0032] The second drive assembly 8 includes a mounting block 81, which is connected to the second guide rail 5, and at least a portion of the mounting block 81 protrudes in a direction away from the second guide rail 5. The second piston cylinder 80 is connected to a side of the mounting block 81 away from the second guide rail 5 so that the telescopic direction of the second piston cylinder is parallel to the extension direction of the second guide rail 5.

[0033] The first drive assembly 7 includes a mounting bracket, which is connected to the bottom of the robot. The mounting bracket has a protrusion protruding in a direction away from the robot. The second piston cylinder is connected to the protrusion of the mounting bracket so that the extension and retraction direction of the second piston cylinder is parallel to the extension direction of the first guide rail 4.

[0034] In the present application, the first piston cylinder 70 and the second piston cylinder 80 are both electric push rods to facilitate automatic control.

[0035] In one embodiment of the present application, the first support structure 1 and the second support structure 2 are both one, there are two first guide rails 4, the two first guide rails 4 are arranged at intervals, and the first support structure 1 and the second support structure 2 are respectively arranged on the two first guide rails 4. In this way, it is possible to prevent the first support structure and the second support structure from colliding and causing damage to the support structure.

[0036] In one embodiment of the present application, the first support structure 1 includes two first support segments 10, the second support structure 2 includes two second support segments 20, there are four first guide rails 4, four second guide rails 5 and four slide assemblies 6, and each of the two first support structures 1 and the two second support structures 2 is provided with a second guide rail 5, a slide assembly 6 and a first guide rail 4. The first guide rail 4 and the second guide rail 5 are connected by corresponding slide assemblies 6. In this way, collisions between the various support structures can be prevented, and damage to the support structures can be further prevented.

[0037] For different usage environments, the distance between the sunshade and the ground is also different, and the sunshade in the prior art cannot be adjusted in height, which makes the use of the sunshade less flexible, and the sunshade is prone to interfere with the ground in different usage environments, thereby causing damage to the sunshade.

[0038] Therefore, the first support structure 1 and the second support structure 2 of the present invention both include: a first support segment 100, used to connect to the bottom of the robot, the first support segment 100 is movably set on the first guide rail 4; a second support segment 200, the second support segment 200 is movably connected to the first support segment 100 to adjust the height of the first support structure 1 and / or the second support structure 2, so that the distance between the light shield and the ground in different environments can be adjusted, so that the light shield avoids the ground in different environments, so as to further prevent interference between the light shield and the ground, causing damage to the light shield.

[0039] Specifically, each first stent segment 10 and each second stent segment 20 of the present invention includes a first stent segment 100 and a second stent segment 200 .

[0040] Specifically, the first support segment 100 includes a plurality of first uprights 101, and the second support segment 200 includes a plurality of second uprights 201. The plurality of first uprights 101 and the plurality of second uprights 201 are connected one-to-one, and one of the first uprights 101 and the second uprights 201 is movably inserted into the other of the first uprights 101 and the second uprights 201; the first support structure 1 and the second support structure 2 both include a first reinforcing support 300, and the first reinforcing support 300 and the plurality of second uprights 201 are arranged at intervals around the circumference of the second support segment 200. The first reinforcing support 300 includes a first reinforcing member 301 and a second reinforcing member 302, and one end of the first reinforcing member 301 is connected to the first support segment 100. The first reinforcing member 301 and the second reinforcing member 302 are movably connected to each other. In this way, the structural stability of the support structure can be enhanced, and through the combined action of the movement between the first reinforcing support 300, the first upright and the second upright, the movement between the first support segment 100 and the second support segment 200 is smooth.

[0041] In the present application, the first reinforcement member 301 and the second reinforcement member 302 are both angle aluminum. The first reinforcement bracket 300 is located at the corner of the first bracket segment 100. The first reinforcement bracket 300 also includes a connector, one end of the first reinforcement member 301 is connected to the first bracket segment 100 via the connector, and the connector is also angle aluminum. The first reinforcement member 301 is provided with a first slide groove, and the second reinforcement member 302 is provided with a second slide groove. The first reinforcement bracket 300 also includes a sliding column, which is provided on the first slide groove and the second slide groove. The sliding column is fixedly connected to one of the first reinforcement member 301 and the second reinforcement member 302 so that the sliding column can be movably provided on the first slide groove or the second slide groove to ensure smooth sliding between the first reinforcement member 301 and the second reinforcement member 302. The extension direction of the first slide groove and the extension direction of the second slide groove are on the same straight line to ensure smooth sliding between the first reinforcement member 301 and the second reinforcement member 302.

[0042] Preferably, there are multiple first reinforcing brackets 300, and multiple first reinforcing brackets 300 and multiple second uprights 201 are arranged at circumferential intervals around the corresponding second bracket segment 200 to enhance the structural stability of the bracket structure and ensure smooth movement between the first bracket segment 100 and the second bracket segment 200.

[0043] In the present application, the sunshade further comprises a second reinforcement bracket 400, which comprises a plurality of sequentially connected reinforcement rods 401, with each reinforcement rod 401 having two ends connected to two adjacent second upright poles 201. The second reinforcement bracket 400 is located on a side of the second upright poles 201 that is away from the first bracket section 100. This enhances the structural stability of the bracket structure.

[0044] Specifically, multiple reinforcing rods 401 are connected in sequence to form a layer of second reinforcing bracket 400. The second reinforcing bracket 400 has multiple layers, and the multiple layers of second reinforcing bracket 400 are arranged at intervals along the extension direction of the second vertical pole 201; two adjacent second reinforcing brackets 400 are connected by a reinforcing connecting rod, thereby further improving the structural stability of the bracket structure.

[0045] The arrangement of the support structure of the sunshade of the present application can ensure that the sunshade has sufficient strength to withstand harsh environments such as strong winds when in use.

[0046] Optionally, the blackout cloth is made of spandex material; or the blackout cloth is made of TPU (thermoplastic polyurethane elastomer rubber) material. In the present application, the blackout cloth is attached to the support structure; specifically, the blackout cloth is attached to the support structure using Velcro.

[0047] Specifically, a fill light is provided in the shielding space 110 of the light shield to provide a light source for the recognition device.

[0048] During actual use, the light shield is kept at a certain distance from the plants. Due to the different directions and brightness of sunlight throughout the day, the sunlight will shine on the plants through the gap between the light shield and the plants. The sunlight is very strong, much stronger than the brightness of the light inside the light shield. Therefore, when the sunlight shines on the plants, the images collected by the recognition sensor are all exposed, and it is impossible to distinguish between crops and weeds. A shielding component is installed at the edge of the light shield on the side close to the ground. The shielding component is similar to the extension shape of the skirt structure (not shown in the figure). The shielding component extends along the circumference of the light shield. In this way, the gap between the light shield and the plants can be blocked by the skirt structure, thereby blocking all excess sunlight, making the area below the operating mechanism completely dark. The brightness within the range recognized by the recognition device all comes from the brightness of the fill light.

[0049] Specifically, the wheel assembly 30 includes a robotic arm and a wheel component that are interconnected. The robotic arm is rotatably connected to the robot body 31, and the wheel component is rotatably connected to the robotic arm. The first support structure 1 and the second support structure 2 both include an avoidance support segment 500. The avoidance support segment 500 is located on the side of the first support segment 100 close to the robot. The avoidance support segment 500 forms an avoidance groove 501. The avoidance groove 501 is used to avoid the robotic arm of the wheel assembly 30. In this way, the wheel assembly 30 can be further avoided to prevent the light shield from interfering with the wheel assembly 30.

[0050] The present invention also provides a robot, including a robot body 31 and multiple wheel assemblies 30, each wheel assembly 30 is movably connected to the robot body 31; an identification device and an operating mechanism, the identification device and the operating mechanism are both arranged at the bottom of the robot body 31 and located on the inner side of the multiple wheel assemblies 30; the above-mentioned light shield, the identification device and the operating mechanism are all located in the shielding space 110 of the light shield.
