A protective cover and a leveling piece are provided to prevent soil and weeds brought up by the blade assembly from spilling during the weeding operation and to restore the ground to a flat surface after the weeding operation. The structure is simple, fast and efficient, and the multifunctional operation of leveling the ground is achieved while improving the weeding efficiency.

[0034] A weed control unit, such as Figure 1 -Attached Figure 5 As shown, it comprises: a housing 1, a protective cover 2, a leveling member 3, a weeding shaft 4 and a plurality of blade groups 5 arranged around the outer periphery of the weeding shaft 4, the weeding shaft 4 and the plurality of blade groups 5 are located in the housing 1, and the weeding shaft 4 is rotatably connected to an external driving mechanism, so that the plurality of blade groups 5 are driven by the external driving mechanism to rotate at a high speed to achieve mowing;

[0035] The leveling piece 3 is located in the housing 1 , and the protective cover 2 is connected to the housing 1 in an openable and closable manner, so as to seal the soil and weeds brought up by the blade assembly 5 in the protective cover 2 and level them through the leveling piece 3 .

[0036] The present embodiment provides a weeding unit, comprising the following components: a housing 1, a protective cover 2, a leveling member 3, a weeding shaft 4, and a plurality of blade groups 5 arranged around the periphery of the weeding shaft 4. In the weeding unit, the weeding shaft 4 and the plurality of blade groups 5 are located inside the housing 1. The weeding shaft 4 is connected to an external driving mechanism, so that the plurality of blade groups 5 are driven to rotate at high speed under the action of the external driving mechanism, thereby realizing a fast and efficient mowing operation on the grass.

[0037] The leveling member 3 is located inside the housing 1, and the protective cover 2 is connected to the housing 1 in an openable and closable manner. When the blade assembly 5 brings up soil and weeds during operation, the protective cover 2 seals them inside to prevent them from scattering. Then, the soil is leveled by the leveling member 3 to ensure that the ground is flat. Such a complete set of devices can effectively cut weeds on the lawn and keep the ground flat.

[0038] In a specific embodiment, it also includes a belt transmission mechanism 6 arranged on the shell 1, one side of the belt transmission mechanism 6 is connected to the external driving mechanism, and the other side is transmission-connected to the weeding shaft 4, which is used to drive the weeding shaft 4 to rotate at high speed under the drive of the external driving mechanism.

[0039] In this embodiment, as shown in the attached Figure 4 As shown, the weeding unit further includes a belt transmission mechanism 6 disposed on the housing 1. One side of the belt transmission mechanism 6 is connected to an external driving mechanism, and the other side is drivingly connected to the weeding shaft 4. Its function is to drive the weeding shaft 4 to rotate at a high speed through the transmission of the belt transmission mechanism 6 when the external driving mechanism is started.

[0040] This design allows the weeding shaft 4 to rotate more stably and effectively in sync with the external drive mechanism, thereby improving the working efficiency and reliability of the entire weeding unit. At the same time, the arrangement of the belt transmission mechanism 6 also makes maintenance and replacement work more convenient, because the belt can be more easily adjusted or replaced to keep the normal operation of the transmission system.

[0041] In a specific embodiment, the leveling member 3 includes a roller; an opening 7 is provided on the side of the shell 1 facing the ground, and the weeding shaft 4 is connected to the inside of the shell 1 and faces the opening 7; both ends of the roller are rotatably connected to the inner wall of the shell 1 to drive the roller to roll when the weeding unit moves to achieve leveling.

[0042] In this embodiment, an opening 7 is designed on the side of the housing 1 of the weeding unit facing the ground. The leveling member 3 and the weeding shaft 4 are connected to the inside of the housing 1 and face the opening 7 .

[0043] The advantage of this design is that the opening 7 can provide a more direct access to the ground for the leveling member 3 and the weeding shaft 4. Through this opening, the leveling member 3 can contact the ground more effectively to ensure the leveling of the soil. At the same time, the weeding shaft 4 can also contact the ground more conveniently, improving the efficiency of the weeding blade in mowing the grass. In addition, the provision of the opening 7 is also conducive to convenient cleaning and maintenance of the components inside the weeding unit, making the operation more convenient. The two ends of the drum are rotatably connected to the inner wall of the housing 1, and this installation method ensures the stability and reliability of the drum. When the weeding unit moves, the drum will be driven to roll, thereby achieving the effect of leveling the ground.

[0044] In a specific embodiment, the weeding shaft 4 is arranged along the width direction a of the housing 1 , and the width direction a is a vertical direction of the moving direction of the weeding unit when performing weeding operations.

[0045] In this embodiment, as shown in the attached Figure 5 As shown, the weeding shaft 4 is arranged along the width direction a of the shell 1. The width direction a here refers to the vertical direction of the moving direction of the weeding unit when performing weeding operations. This design takes into account the movement mode of the weeding unit in actual operation, and the weeding shaft 4 is arranged in the width direction a of the shell 1 so that it is perpendicular to the weeding direction. Such an arrangement ensures that the weeding shaft 4 can cover the entire operating area more effectively, thereby improving the coverage rate and efficiency of the weeding operation. At the same time, this also makes the operation of the weeding shaft 4 more stable, reduces the swaying and instability factors during the operation, and thus improves the quality and effect of the weeding operation.

[0046] In a specific embodiment, the leveling member 3 is arranged along the width direction a of the housing 1 , and the width direction a is a vertical direction of the moving direction of the weeding unit during weeding operation.

[0047] In this embodiment, the leveling piece 3 is arranged along the width direction a of the shell 1. The width direction a here refers to the direction in which the weeding unit moves when performing weeding operations, which is a vertical direction relative to the working area. The leveling piece 3 is arranged on the shell 1 along the width direction a to ensure that it can effectively contact the ground and perform leveling operations. Such a design takes into account the actual needs of the weeding operation, so that the leveling piece 3 can better adapt to the ground of different terrains and ensure the flatness and consistency of the working area. At the same time, arranging the leveling piece 3 along the width direction a can also improve the stability and operability of the weeding unit, making it more reliable and efficient in actual use.

[0048] In a specific embodiment, each blade set 5 includes a plurality of blades 51 spaced apart in the radial direction of the weeding shaft 4 , and the plurality of blades 51 face the opening 7 .

[0049] In this embodiment, as shown in the attached Figure 1 and attached Figure 2 As shown, each blade set 5 is composed of a plurality of blades 51, and these blades 51 are arranged at intervals along the radial direction of the weeding shaft 4. The arrangement of the blades 51 follows a certain spacing to ensure that each blade 51 can fully play a role in the weeding operation and cover the entire working area. In practical applications, the number of blades 51 can be selected according to actual needs to achieve the unity of efficient weeding and cost reduction.

[0050] The blades 51 are all facing the opening 7 of the housing 1, and this design ensures that the blades 51 can effectively cut the grass when they come into contact with it. The direction of the blades 51 toward the opening 7 enables them to cut more smoothly when they come into contact with the ground, thereby improving the efficiency and quality of weeding. In addition, the radial spacing of the blades 51 also ensures that the weeding shaft 4 can evenly cover the entire working area when rotating, making the weeding operation more uniform and thorough.

[0051] In a specific embodiment, the protective cover 2 is fully or partially sealedly connected to the housing 1 through the opening 7 .

[0052] In this embodiment, the protective cover 2 is fully or partially sealed to the housing 1 through the opening 7. Such a design helps to ensure that grass, debris or other debris will not splash out from the opening 7 during the operation, protecting the surrounding environment and the safety of the operator. It can also effectively prevent dust, debris and other materials generated during the weeding operation from splashing into the surrounding environment, reducing the difficulty of cleaning work and the possibility of environmental pollution. At the same time, the sealed connection between the protective cover 2 and the housing 1 can also extend the service life of the equipment and reduce damage and wear caused by external environmental factors.

[0053] In a specific embodiment, a traveling mechanism 8 is further included. The traveling mechanism 8 is connected to the housing 1 and to an external driving mechanism, and is used to drive the weeding unit to move under the drive of the external driving mechanism.

[0054] In this embodiment, as shown in the attached Figure 4 As shown, the walking mechanism 8 is also included. The walking mechanism 8 is tightly connected to the housing 1 and is connected to an external driving mechanism. Its main function is to drive the weeding unit to move under the external drive. The design of the walking mechanism 8 takes into account the movement requirements of the weeding unit under different terrains, so it may use wheels, tracks or other types of mobile devices. Such a design enables the weeding unit to move smoothly on grass, mud or other various terrains, ensuring the continuity and efficiency of the operation.

[0055] The external driving mechanism provides power to the traveling mechanism 8 and controls its moving direction and speed by connecting to the traveling mechanism 8. The external driving mechanism can be an electric drive, a hydraulic drive or other types of driving devices, and the selection depends on the actual application requirements and environmental conditions. Through the function of the traveling mechanism 8, the weeding unit can move freely in different terrains, flexibly adapt to various working environments, and achieve efficient weeding operations.

[0056] In a specific embodiment, at least two blade groups 5 are included. Each blade group 5 is evenly arranged around the periphery of the weeding shaft 4, and each blade group 5 includes a plurality of blades 51 spaced apart in the radial direction of the weeding shaft 4.

[0057] In this embodiment, as shown in the attached Figure 2 As shown, the weeding device includes four blade groups 5. Each blade group 5 is evenly arranged around the periphery of the weeding shaft 4 to ensure full coverage of the lawn or crop, thereby improving the efficiency and coverage area of ​​weeding. In addition, each blade group 5 includes a plurality of blades 51, which are arranged at intervals along the radial direction of the weeding shaft 4 to achieve more uniform and comprehensive cutting. The intervals between the blade groups 5 enable the weeding shaft 4 to produce a balanced and stable rotational motion, thereby avoiding unnecessary vibration and uneven cutting effects.

[0058] In addition, the radial spacing of the blade set 5 also helps prevent excessive loss and wear caused by continuous cutting, prolongs the service life of the blade set, and reduces the frequency of maintenance and replacement. Such a design not only improves the performance and efficiency of the weeding device, but also reduces the cost of use and maintenance, bringing users a more convenient and economical weeding solution.
