Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to the overall structure of an unmanned lawnmower. Background Technology

[0002] A lawnmower is a device suitable for automated mowing of outdoor lawns. Existing unmanned lawnmowers have three operating modes: manual driving, remote control, and automatic driving. Therefore, unmanned lawnmowers need to have a vehicle-like structure that allows for human riding. Some existing lawnmowers discharge grass from the side, directly scattering it onto the grass. This is more suitable for lawn mowing as it doesn't require collection. However, for lawns that need to be collected centrally, directional conveying and collection of the grass is necessary. Furthermore, the layout design of existing lawnmowers directly affects their working efficiency, ease of operation, and overall performance. A reasonable layout can optimize space utilization and improve user experience, while an unreasonable layout may lead to a bulky machine, inconvenient operation, and difficult maintenance.

[0003] To address these issues, we have provided a complete vehicle structure for unmanned lawnmowers. Utility Model Content

[0004] The purpose of this utility model is to provide an unmanned lawnmower vehicle structure, rationally optimize the layout design of the lawnmower, improve the overall performance of the lawnmower, and make the lawnmower easy to ride and collect hay.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an unmanned lawnmower vehicle structure, including a riding-type frame and integrated components such as a front wheel, rear wheel, mowing mechanism, steering wheel, seat, engine, grass collection mechanism, and rear end plate. The mowing mechanism is located between the front wheel and rear wheel below the frame. The rear wheel and mowing mechanism are driven by the engine through a transmission mechanism. The engine is fixed at the front of the frame, and the front housing of the frame is open at the engine position. The rear end plate is provided with a grass collection box mounting bracket, and the height of the grass collection box mounting bracket is lower than the height of the frame. The grass-collecting mechanism includes a suction fan, a collection hood, and a collection channel. The suction fan is driven by a hydraulic motor. The suction end of the suction fan is connected to the output end of the grass-cutting mechanism through the collection hood. The discharge end of the suction fan is connected to the collection channel. The collection channel extends to the rear of the vehicle frame and connects to the rear end plate. The collection channel is housed at the bottom of the vehicle frame and positioned above the grass-cutting mechanism.

[0006] Preferably, the middle part of the collection channel is fixed to the seat mounting bracket of the vehicle frame, the seat mounting bracket is located at the rear of the vehicle frame, and the seat is fixed to the seat mounting bracket.

[0007] Preferably, the mowing mechanism is equipped with two sets of parallel rotating blades.

[0008] Preferably, the transmission mechanism includes a V-belt drive mechanism, a primary belt drive mechanism, a secondary belt drive mechanism, and a bevel gear commutator; The engine drives the double-set rotating blades of the mowing mechanism to rotate via a V-belt transmission mechanism. The engine drives the rear wheel axle to rotate through a primary belt drive mechanism, a secondary belt drive mechanism, and a bevel gear commutator in sequence. The rear wheel axle is connected to the output end of the bevel gear commutator.

[0009] Preferably, the output end of the engine is connected to the drive pulley of the V-belt drive mechanism and the drive pulley of the primary belt drive mechanism.

[0010] Preferably, the engine is fixed to a chassis bracket at the front of the vehicle frame.

[0011] This utility model has the following beneficial effects: 1. The riding frame design facilitates manual driving, and the open engine design provides good heat dissipation and easy maintenance. The engine is located at the front, the mowing mechanism is in the middle, and the hay box is located at the rear via the hay box mounting bracket, ensuring a uniform center of gravity distribution and preventing tipping over. The reasonable distribution of space makes good use of the space and also facilitates rear wheel propulsion. 2. The grass harvested by the mowing mechanism is directionally conveyed and concentrated by the suction fan and thrown backward for easy collection. The suction fan avoids blockage or grass accumulation around the rotating blades of the mowing mechanism, and the backward throwing avoids grass contamination of the vehicle frame and engine. 3. The hay collection box is mounted on a low position on the hay collection box mounting frame, ensuring a stable center of gravity; 4. The height difference between the front and rear ends of the collection channel is small, the collection channel is reasonably designed, and the hay is not easily blocked; 5. The design positions of the mowing mechanism, engine, and grass-collecting mechanism result in a low center of gravity, compact layout, stable chassis, and small size for the entire vehicle.
