[0014] (III) Beneficial Effects

[0015] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. The transmission mechanism can be set so that one motor can drive the mowing mechanism and the conveying mechanism at the same time. Since the speed of the mowing mechanism is greater than that of the conveying mechanism, the number of teeth of the third gear is set to be greater than the number of teeth of the second gear.

[0017] 2. Setting the conveyor belt to be higher on one side and lower on the other side facilitates the transfer of the material to be cut into the material bin. The material bin is used to collect the grass, avoiding secondary cleaning by manual or machine personnel. The grass-gathering roller is used to collect the weeds for the cutting mechanism to cut.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1-2 As shown: An intelligent weeding robot for agricultural machinery includes a body 1. Inside the body 1, there are sequentially formed a feed inlet 11, a working chamber 12, and a discharge chamber 13. Multiple guide plates 14 are installed inside the working chamber 12, arranged side-by-side with intervals for guiding the material. A ramp 15 is provided on one side of each guide plate 14 to allow the cut material to fall onto a conveyor belt 32.

[0024] The working chamber 12 is equipped with a mowing mechanism 2 and a conveying mechanism 3. The mowing mechanism 2 is located above the guide plate 14, and the conveying mechanism 3 is located on one side of the slope 15. The machine body 1 is equipped with a transmission mechanism for connecting the mowing mechanism 2 and the conveying mechanism 3. The bottom of the machine body 1 is provided with a base plate 16, and the discharge chamber 13 is provided with a material box 4.

[0025] The mowing mechanism 2 includes a connecting rod 21, a turntable 22, and a cutter 23. The connecting rod 21 is rotatably connected in the working chamber 12. The turntable 22 is installed at the bottom of the connecting rod 21. The cutter 23 is installed on the turntable 22 at equal distances around the axis. The turntable 22 is arranged parallel to the guide plate 14. The parallel arrangement can facilitate the cutting of the mowing mechanism 2.

[0026] The conveying mechanism 3 includes a rotating roller 31 and a conveyor belt 32. The rotating roller 31 is rotatably connected to the working chamber 12, and the conveyor belt 32 is sleeved on the rotating roller 31. One end of the conveyor belt 32 is located below the slope 15 and the other end is located above the material box 4. Setting the conveyor belt 32 to be high on one side and low on the other side can facilitate the conveying of the material to be cut into the material box 4.

[0027] The transmission mechanism includes a motor 5, a bevel gear 51, a first gear 52, a first rotating shaft 53, a second rotating shaft 55, a second gear 56, and a third gear 57. The motor 5 is installed inside the machine body 1. The first rotating shaft 53 is installed at the bottom of the motor 5. The bevel gear 51 is installed at the top of the connecting rod 21. The first gear 52 is installed on the first rotating shaft 53 and meshes with the bevel gear 51. The second rotating shaft 55 is rotatably installed inside the machine body 1. The second gear 56 is installed at the bottom of the second rotating shaft 55. The third gear 57 is installed on the rotating roller 31 and meshes with the second gear 56. A belt 54 is sleeved on the first rotating shaft 53 and the second rotating shaft 55. The third gear 57 has more teeth than the second gear 56.

[0028] The transmission mechanism allows one motor to drive both the mowing mechanism 2 and the conveying mechanism 3 simultaneously. Since the rotational speed of the mowing mechanism 2 is greater than that of the conveying mechanism 3, the number of teeth on the third gear 57 is set to be greater than the number of teeth on the second gear 56.

[0029] A grass-gathering roller 6 is rotatably connected inside the feed inlet 11. The grass-gathering roller 6 is used to gather the weeds so that the cutting mechanism 2 can cut them.
