Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to a dual-blade transmission structure for a remote-controlled lawnmower. Background Technology

[0002] As people's demands for the quality of their living environment increase, lawn mowers are being used more and more widely in areas such as lawn maintenance and garden trimming. In particular, remote-controlled lawn mowers are favored by users because of their convenient operation and ability to adapt to complex terrain.

[0003] However, traditional lawnmowers have many shortcomings in terms of operation and power transmission. Some lawnmowers require direct manual operation, which is labor-intensive, inefficient, and poses significant risks to operators in complex terrain or dangerous areas. While remote-controlled lawnmowers solve the safety issues, their power drive systems suffer from problems such as large cutting radii, high energy consumption, and easy belt wear in some single-blade lawnmowers. Many dual-blade lawnmowers use dual power sources to drive two blades separately, increasing overall cost and energy consumption. Furthermore, some belt-driven dual-blade lawnmowers suffer from poorly designed belt drive structures, using multiple pulleys that cause repeated belt bending, resulting in complex structures, numerous friction points, rapid wear, and short lifespan, affecting the normal use and efficiency of the lawnmower. Therefore, a new technology is needed to solve these problems. Utility Model Content

[0004] This utility model provides a dual-blade transmission structure for a remote-controlled lawnmower, which solves the problems of increased cost caused by dual power sources driving two blade discs separately, and unreasonable belt drive structure design leading to multiple friction points, rapid wear, and short lifespan. It significantly simplifies the power system of the lawnmower, effectively reduces costs and energy consumption, and achieves lawnmowing operations that are simple and reasonable in structure, convenient in installation and maintenance, have a long belt lifespan, and are highly efficient and energy-saving.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-blade transmission structure for a remote-controlled lawnmower, comprising a hanging plate, an engine, a blade assembly, and a transmission component. The engine and the blade assembly are fixedly mounted on the upper surface of the hanging plate, and the blade assemblies are respectively fixedly mounted on the left and right sides of the upper surface of the hanging plate. The engine drives the transmission component, and the transmission component drives the blades. Using the engine as the sole power source, the two blade discs are driven through two V-belts and a cleverly designed combination of pulleys and tensioners. Compared with the traditional dual-power-source drive, this design significantly simplifies the lawnmower's power system and effectively reduces costs and energy consumption.

[0006] Furthermore, a square protective cover is provided above the transmission assembly, and an engine clearance opening is provided above the protective cover. The main body of the engine is mounted above the protective cover through the engine clearance opening.

[0007] Furthermore, an engine protective cover is provided above the engine, with an opening on the inside of the engine protective cover, and heat dissipation holes are provided on both the front and rear sides of the engine protective cover.

[0008] Furthermore, the transmission assembly includes an engine pulley, a first cutter head drive pulley, and a second cutter head drive pulley. The engine output end is connected to the engine pulley via an engine belt drive. The engine pulley is a pulley with two or more grooves and is located in the middle of the upper surface of the hanging plate. The upper part of the cutter head assembly is provided with the first cutter head drive pulley and the second cutter head drive pulley. The first cutter head drive pulley, the engine pulley, and the second cutter head drive pulley are sequentially connected by a transmission belt. A rotating shaft is provided below the first cutter head drive pulley and the second cutter head drive pulley. The rotating shaft passes through the cutter head assembly and extends downward.

[0009] Furthermore, a belt tensioning assembly is provided between the first tool holder drive wheel and the engine pulley, and a belt tensioning assembly is provided between the engine pulley and the second tool holder drive wheel.

[0010] Furthermore, the belt tensioning assembly one and belt tensioning assembly two have the same structure, both including a tensioning wheel, a mounting base and an electric push rod. The bottom of the electric push rod is fixedly mounted on the upper surface of the hanging plate, and the output end is fixedly connected to the vertical section of the L-shaped mounting base. A tensioning wheel is installed below the horizontal section of the mounting base, and the outer side of the tensioning wheel is rotatably connected to the transmission belt.

[0011] Furthermore, tension wheel clearance openings are provided on the front and right sides of the protective cover, and a pulley clearance opening is provided on the top.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The dual-blade transmission structure of this remote-controlled lawnmower has the following advantages:

[0013] Simple and rational structure: Utilizing a single power source and a clever belt drive structure to drive dual blades, compared to dual-power source drives, this reduces power equipment, simplifies the overall structure, and lowers costs and energy consumption. Its advantages are more pronounced compared to wide-width single-blade lawnmowers. The shorter blade working radius increases the cutting torque, significantly improving mowing performance, reducing engine output torque, and lowering fuel consumption. It eliminates the traditional direct connection between the engine and blades, preventing damage to the engine from hitting hard objects during mowing, thus reducing maintenance rates and costs.

[0014] Easy installation and maintenance: Due to its simplified structure, the installation and disassembly of each component are more convenient, facilitating routine maintenance and troubleshooting by repair personnel. Belt replacement is also easier, reducing maintenance costs and time.

[0015] Long belt life: Reduced bending and friction points on the belt decrease wear and tear, thus significantly extending its lifespan, reducing downtime due to belt replacement, and improving the lawnmower's efficiency. Attached Figure Description

[0026] Among them, such as Figure 6-7 As shown, the transmission assembly includes an engine pulley 6, a first cutter head drive pulley 7, and a second cutter head drive pulley 8. The output end of the engine 2 is connected to the engine pulley 6 via an engine belt 12.
