A valve 212 is installed at the lower end of the irregular discharge pipe 28. The valve 212 is connected to the control panel 20.

[0027] The specific settings and functions of this embodiment are described below. The base 1, as the core load-bearing structure of the entire lawnmower, is made of high-strength alloy material. This material not only has excellent pressure resistance and deformation resistance, which can stably support the operation of each component, but also reduces the overall weight through lightweight design, making the lawnmower easier for a single person to carry and move, thus improving portability.

[0028] The power system 13 is installed at the top of the base 1 and uses a high-torque DC motor. This motor has the characteristics of rapid start-up and stable power output. It can provide continuous and strong power according to the actual conditions of the lawn (such as grass density and height) to ensure efficient cutting operations. Its output end is tightly connected to the cutting blade 15 and can accurately transmit power.

[0029] The cutting blade 15 is installed at the output end of the power system 13. It is made of high-quality high-manganese steel and has undergone professional quenching treatment. This gives the blade extremely high hardness and sharpness. It can not only quickly cut various weeds, but also effectively resist wear during the cutting process and extend its service life. It can easily handle even thicker and harder grass stems.

[0030] The self-cleaning mechanism 2 is located at one end of the base 1 and is the key part for realizing the automatic collection and processing of grass clippings, which greatly reduces the amount of manual cleaning work.

[0031] The grass collection box body 21 is made of transparent high-strength engineering plastic, allowing users to visually observe the amount of grass clippings collected inside and process them in a timely manner. Its internal space has been optimized to hold more grass clippings, reducing the frequency of processing.

[0032] The control panel 20 is installed on the top of the grass collection box body 21. The panel is equipped with clear function buttons and a high-definition display screen. Users can easily control the start, stop, speed adjustment and other functions of the lawnmower through the buttons. The display screen shows the operating parameters such as motor speed and grass clipping collection amount in real time, so that users can have a clear understanding of the equipment status.

[0033] The discharge hole 22 penetrates the inner wall of the circular groove at the lower end of the base 1. Its diameter and shape match the opening of the grass collection box body 21, ensuring that the cut grass clippings can smoothly enter the grass collection box from the circular groove of the base 1, preventing grass clippings from accumulating inside the base 1 and affecting equipment operation. The roller brush 23 is rotatably installed inside the grass collection box body 21, with dense and elastic nylon bristles distributed on its surface. During rotation, the bristles thoroughly sweep the grass clippings near the discharge hole 22 and at the entrance of the grass collection box into the inside of the collection box, preventing grass clippings from clogging the discharge hole 22 and ensuring smooth operation. To ensure the smooth flow of the grass clipping collection channel, the first servo motor 24 is installed on one side of the grass collection box body 21. It features high precision and adjustable speed, providing power for the rotation of the roller brush 23. Its speed can be precisely adjusted through the control panel 20 to adapt to the collection needs of different amounts of grass clipping. One end of the first rotating rod 25 is fixedly connected to the output end of the first servo motor 24, and the other end is fixed to one end of the roller brush 23, which plays the role of transmitting power. It is made of high-strength metal material, which can stably transmit the torque of the motor and ensure that the roller brush 23 rotates smoothly.

[0034] The second servo motor 26 is installed at the other end of the grass collection box body 21. It also has the characteristics of high-precision control and speed adjustment, providing power for the conveying and cutting of grass clippings. The speed can be flexibly adjusted according to the amount of grass clippings processed. The second rotating rod 29 is rotatably installed inside the grass collection box body 21. It is made of high-strength alloy material, which has good rigidity and wear resistance. It can work stably under high-speed rotation and provide stable support for the spiral blade 210 and the cutting component 211. The spiral blade 210 is installed on the outer wall of the second rotating rod 29. The pitch and angle of the blade are carefully designed. Driven by the second rotating rod 29, it can smoothly and efficiently push the grass clippings in the grass collection box towards the shaped discharge pipe 28, ensuring uniform conveying of grass clippings. The cutting component 211 is installed on the outer wall of the second rotating rod 29 and near the edge. It consists of multiple sharp blades. When the second rotating rod 29 rotates, the blades rotate at high speed to perform secondary cutting and crushing of the grass clippings conveyed by the spiral blade 210, cutting the grass clippings into smaller fragments for easy discharge and subsequent degradation treatment.

[0035] The first rotating rod 25 connects the first servo motor 24 to the roller brush 23 to achieve power transmission; the second rotating rod 29 connects the second servo motor 26 to the spiral blade 210 and the cutting assembly 211 to ensure coordinated operation; the first servo motor 24, the second servo motor 26, and the valve 212 are all connected to the control panel 20 for signal transmission to achieve centralized control; the grass collection box body 21 is fixed to the base 1, and its opening is flush with the discharge hole 22 to ensure smooth grass clipping collection; the power system 13 and the self-cleaning mechanism 2 are electrically connected to the battery 12 to obtain power supply.

[0036] The irregular discharge pipe 28 is installed through one side of the grass collection box body 21. Its pipe shape has been optimized by fluid dynamics and its interior is smooth, which can effectively reduce the resistance when grass clippings are discharged, prevent grass clippings from clogging the pipe, and allow grass clippings to be discharged smoothly.

[0037] The protective arc plate 27 is installed on the other side of the grass collection box body 21 and located to one side of the second servo motor 26. It is made of wear-resistant rubber material and can effectively prevent grass clippings from splashing onto the second servo motor 26, preventing the motor from being contaminated or damaged by grass clippings. At the same time, it can also play a buffer protection role during equipment movement, extending the service life of the motor. The valve 212 is installed at the lower end of the special-shaped discharge pipe 28 and is connected to the control panel 20. The user can precisely control the opening degree and on / off state of the valve 212 through the control panel 20, and adjust the discharge speed according to the grass clipping discharge requirements to avoid waste caused by excessively fast grass clipping discharge or blockage caused by excessively slow discharge.

[0038] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, a walking mechanism 11 is installed at the lower end of the base 1, a storage battery 12 is installed at the upper end of the base 1, a foldable handrail mechanism 14 is installed at the upper end of the base 1, and the power system 13 and the self-cleaning mechanism 2 are both electrically connected to the storage battery 12.

[0039] The overall effect of this embodiment is that the walking mechanism 11 is installed at the lower end of the base 1 and adopts a universal wheel design with a braking function. The universal wheel is made of high elastic rubber material, which has good shock absorption and grip, allowing the lawnmower to move flexibly on different terrains such as lawns and slopes. The braking function can fix the position of the equipment at any time, improving operational safety.

[0040] The battery 12 is installed on the upper part of the base 1. It is a high-capacity lithium battery with high capacity, fast charging speed and long cycle life. It provides stable power support for the power system 13 and the self-cleaning mechanism 2. Compared with traditional fuel power, it is more energy-saving and environmentally friendly, and does not require frequent refueling, resulting in low operating costs. The foldable armrest mechanism 14 is installed on the upper part of the base 1. The armrest height can be adjusted according to the user's height. The surface of the armrest is covered with a non-slip rubber sleeve to improve operating comfort. When not in use, the armrest can be folded, which greatly reduces the storage space of the equipment and facilitates transportation and storage.

[0041] The usage and working principle of this device are as follows: During the mowing process, the user pushes the lawnmower through the foldable handle mechanism 14. The universal wheels of the walking mechanism 11 drive the device to move on the lawn. If a fixed position is required, the braking function can be activated. After the device is started, the battery 12 supplies power to the power system 13, and the high-torque DC motor runs. Its output end drives the cutting blade 15 to rotate at high speed. The cutting blade 15 is made of high-quality high-manganese steel and has been quenched. With its high hardness and sharpness, it can quickly cut the weeds on the lawn. Regardless of the density or height of the grass, it can efficiently complete the cutting operation.

[0042] The grass clipping collection process is dominated by the self-cleaning mechanism 2. The cut grass clippings are carried into the circular groove at the lower end of the base 1 by the airflow generated by the rotation of the cutting blade 15. Then, they enter the grass collection box body 21 through the discharge hole 22 that is opened through the inner wall of the circular groove. At this time, the first servo motor 24 is started under the control of the control panel 20. The first rotating rod 25 drives the roller brush 23 to rotate. The dense and elastic nylon bristles on the surface of the roller brush 23 thoroughly sweep the grass clippings near the discharge hole 22 and at the entrance of the grass collection box into the grass collection box, preventing grass clipping blockage and ensuring that the collection channel is unobstructed. Users can intuitively observe the amount of grass clippings inside the grass collection box body 21 through the transparent material.

[0043] The grass clipping treatment process further improves operational efficiency and environmental friendliness. When grass clippings accumulate to a certain level in the grass collection box, the second servo motor 26 starts under the control of the control panel 20. It drives the spiral blades 210 and the cutting component 211 to rotate via the second rotating rod 29. The spiral blades 210 smoothly and efficiently convey the grass clippings towards the shaped discharge pipe 28 with a reasonable pitch and angle. At the same time, multiple sharp blades of the cutting component 211 rotate at high speed to perform secondary cutting and crushing of the conveyed grass clippings, cutting them into smaller fragments. Afterward, the user controls the valve 212 to open via the control panel 20. The crushed grass clippings are discharged through the shaped discharge pipe 28, facilitating their natural degradation on the lawn. The opening degree of the valve 212 is adjustable to control the discharge speed and avoid blockage or waste. The protective arc plate 27 prevents grass clippings from splashing onto the second servo motor 26 during this process, thus providing protection.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
