Detailed Implementation

[0022] Below, in conjunction with Figures 1-6 The present invention describes a disc-shaped weeding robot, comprising a frame and rotating blades. The frame 6 has a vertically placed partition 5 in its center. The frame 6 in front of the partition 5 is rectangular. Several fixed seats 14 are provided on the rectangular frame 6. A suspended platform 2 is provided within the rectangular frame 6. Several connecting seats 15 are provided around the perimeter of the suspended platform 2, and the connecting seats 15 are movably connected to the fixed seats 14. An electric push rod 11 is provided on each of the left and right sides of the suspended platform 2. One end of the electric push rod 11 is movably connected to the suspended platform 2, and the other end of the electric push rod 11 is fixed to the partition 5. Arc-shaped adaptive sides 9 are provided on the left and right sides of the bottom of the suspended platform 2.

[0023] Thus, with the help of the electric actuator 11, connecting seat 15, and fixing seat 14, the arc-shaped adaptive side 9 at the bottom of the suspended platform 2 can move the suspended platform up and down, ensuring that the cutting points of weeding are at the same height in uneven working environments, thus ensuring the weeding effect.

[0024] The connecting seat 15 corresponds one-to-one with the fixed seat 14, and the connecting seat 15 is rotatably connected to the fixed seat 14.

[0025] like Figure 5 As shown, when the suspended platform is at its lowest point, the connecting seat 15 and the fixed seat 14 rotate to be in an up-down position, as... Figure 6 As shown, when the suspended platform is at its highest point, the connecting seat 15 and the fixed seat 14 rotate to their front and rear positions.

[0026] The suspension platform 2 is provided with slide seats 12 on the left and right sides respectively. A strip-shaped groove is opened above the slide seat 12, and one end of the electric push rod 11 is provided in the strip-shaped groove. The electric push rod 11 is slidably connected to the suspension platform 2 through the slide seat 12.

[0027] like Figure 5 As shown, when the suspended platform is at its lowest point, one end of the electric actuator 11 is at the rearmost end of the slide block 12, as... Figure 6 As shown, when the suspended platform is at its highest point, one end of the electric actuator 11 is at the foremost end of the slide block 12.

[0028] The upper portion of the suspension platform 2 is provided with a weeding motor 10, the output end of the weeding motor 10 penetrates the suspension platform 2 and is connected with the rotary blade 8 arranged below the suspension platform 2, and the front and rear sides of the bottom of the suspension platform 2 are respectively provided with rubber cloth 7.

[0029] The bottom height of the arc-shaped adaptive side 9 and the rubber cloth 7 is lower than the height of the rotary blade 8.

[0030] Therefore, the rubber cloth 7 and the arc-shaped adaptive side 9 on the left and right sides of the suspension platform 2 can ensure that the working area of the rotary blade 8 is in a relatively closed state, so that the soil, turf and other debris generated by weeding cannot invade the upper portion of the suspension platform 2, and the service life of the weeding motor 10 is prolonged.

[0031] The left and right sides of the frame 6 are respectively provided with a set of track wheels 4.

[0032] The rear portion of the frame 6 is sequentially provided with a battery pack 17 and an industrial computer 16 from rear to front, and the frame 6 on the left and right sides of the battery pack 17 is respectively provided with a driving assembly 1, the outer side of the driving assembly 1 is provided with a transmission shaft 13, and the driving assembly 1 is connected with the track wheels 4 through the transmission shaft 13.

[0033] Therefore, the disc weeding robot drives the track wheels 4 on the left and right sides of the frame 6 to move through the independent driving assembly 1, and is powered by the battery pack 17 and controlled by the industrial computer 16. Meanwhile, the frame 6 is further provided with a cover shell, which covers the battery pack 17, the industrial computer 16, the suspension platform 2, the driving assembly 1 and other machines.

[0034] The front side of the frame 6 is provided with a bumper 3.

[0035] The above has described the present application by way of example in connection with the drawings, and obviously the specific implementation of the present application is not limited by the above-mentioned embodiments.

[0036] The utility model discloses when using, the arc self -adaptation side 9 of suspension platform 2 bottom, when touching to the uneven place of operation soil height, will promote the whole suspension platform 2 rise or drop. Among them, when rising, the one end of electric push rod 11 will slide on slide 12 along the strip groove of slide 12 to the back, simultaneously, the connecting seat 15 on suspension platform 2 and the fixed seat 14 on car frame 6 will change from up and down position to front and back position, when dropping, the one end of electric push rod 11 will slide on slide 12 along the strip groove of slide 12 to the front, simultaneously, the connecting seat 15 on suspension platform 2 and the fixed seat 14 on car frame will change from front and back position to up and down position. Thus, when encountering uneven operation area in the process of weeding, can guarantee the unity of mowing height, ensure the mowing effect. And, the four around below suspension platform 2 are equipped with left and right two sides self -adaptation side 9 and front and back two sides rubber cloth 7 respectively, cooperate operation soil and form relatively closed space, and the height of rotary cutter 8 is in relatively closed space, so that the soil, weeds and other debris produced in the process of weeding rotary cutter 8 will not invade into the car above suspension platform 2, that is, can reduce the frequency of cleaning also can improve the service life of weeding motor 10 and other machines.

[0037] It should be understood that the utility model can freely combine each part in the embodiments or appropriately deform and omit each part in the embodiments within the scope of the utility model.
