Detailed Implementation
[0021] As shown in the figure, this utility model achieves high-power drive by using a diesel or gasoline internal combustion engine. A support structure is installed inside the front hay cutter compartment to constrain the working height of the entire compartment, preventing uneven ground from affecting the operation of the entire device. Its specific improvements are as follows: Example
[0022] As shown in the attached diagram, a grass-cutting robot includes a frame 1. The frame 1 is equipped with a diesel or gasoline internal combustion engine for high-power drive. In this embodiment, a diesel engine is used as the driving mechanism. The robot has drive frames 2 on both sides of the frame 1. Each drive frame 2 has a track assembly and drive wheels. Specifically, each side of the drive frame 2 has several movable wheels 23. Hub seats 21 are located at the rear ends of both sides of the drive frame 2. Each hub seat 21 is connected to a drive hub 22, and a drive wheel is mounted on each drive hub 22. The track structure ensures stability when the device is running on the ground and is suitable for travel in any road condition.
[0023] like Figure 5 As shown, the drive frame 2 is provided with a hinge part 15, and a swing frame 10 is hinged and fixed through the hinge part 15. The swing frame 10 is provided with a mower compartment 4. A lifting drive cylinder 13 is provided between the mower compartment 4 or the swing frame 10 and the drive frame 2. In this embodiment, a fixed shaft 14 and a drive seat 12 are specifically provided on the rear side of the mower compartment 4. The drive seat 12 is connected and fixed to the swing frame 10 as a whole. A lifting drive cylinder 13 is provided between the drive seat 12 and the lifting cylinder seat 11. The lifting cylinder seat 11 is fixed on the frame 1. By driving the lifting drive cylinder 13, the entire mower compartment 4 can be rotated in place around the hinge part 15 as a fulcrum, thereby achieving vertical lifting.
[0024] This utility model includes a trimming roller 47 inside the trimmer chamber 4, with several blade holders 471 on the trimming roller 47, and each blade holder 471 equipped with a crushing blade 472; furthermore, as Figure 6As shown, the crushing blade 472 is a Y-shaped blade, which is bolted to the blade holder 471 and can be replaced during maintenance and repair, making it convenient for maintenance.
[0025] The key design feature of this invention is that a support portion is provided on the lower rear side of the mowing roller 47. In this embodiment, the support portion is a support roller 48 located at the bottom of the mowing machine chamber 4, which is used to constrain the working height of the entire mowing machine chamber 4. During mowing operations, the support roller 48 can contact the bottom surface, preventing the entire mowing machine chamber 4 from dragging on the ground and causing damage to the bottom surface of the mowing machine chamber 4.
[0026] This utility model has an engine cover 5 on the upper part of the drive frame 1, which provides top surface protection for the engine. A grille protective cover 51 is provided on the rear side of the engine cover 5, which is used for support, protection and heat dissipation.
[0027] Because this invention is a high-power device, it can cut and crush vines or larger weeds. However, when cutting large weeds, the discharge port of the cutter chamber 4 is designed to be open. For example, a flip-top cover 41 is provided on the top front side of the cutter chamber 4, and a driven seat 44 is provided on the top of the flip-top cover 41. A drive seat 45 is correspondingly provided on the cutter chamber 4, and a flip-top drive cylinder 46 is provided between the drive seat 45 and the driven seat 44. With the above structural design, when the device is running, if it encounters thick or large weeds, the flip-top cover 41 can be opened and adjusted to avoid the accumulation of weeds caused by a small discharge port of the cutter chamber 4, which would cause a sudden increase in drive power and thus cause the engine to stall.
[0028] In summary, this utility model, with its above-described structural design, employs a high-power driven track structure, ensuring stable operation of the trimmer chamber 4. When moving on the ground, it can be flexibly adjusted according to actual working conditions. A support section is provided at the rear of the trimmer roller 47 to constrain the working height of the entire trimmer chamber 4, preventing uneven ground from affecting the operation of the entire equipment. This utility model uses a diesel engine drive, enabling it to remove larger weeds. Furthermore, a controllable flip-top cover 41 is provided on the trimmer chamber 4. By controlling the lifting height of the flip-top cover 41, the front grass discharge area can be adjusted. When removing vines, this prevents congestion inside the trimmer chamber, avoiding a sudden increase in power that could damage the equipment.
