A disc mower is a common agricultural machine used for mowing. Below is a detailed introduction:
Structural Components
Cutting System: Consists of multiple disc blades, each typically equipped with two to four blades. The blades are typically made of high-quality steel and undergo a special heat treatment process for excellent wear resistance and sharpness, enabling them to quickly and efficiently cut grass or weeds.
Drive System: This primarily includes components such as pulleys, a gearbox, and a drive shaft. Tractor power is transmitted via the pulley to the gearbox, where it is then transferred through the gears to the drive shaft, causing the disc blades to rotate at high speeds to achieve the desired cutting effect.
Suspension System: This connects the mower to the tractor. Common suspension options include three-point and traction suspension. The suspension system also features springs or hydraulics, allowing the mower to automatically adjust its height based on the undulations of the ground during operation, maintaining the proper distance between the blades and the ground for optimal ground contouring.
The frame structure is the supporting skeleton of the mower. It is typically welded from high-strength steel and possesses sufficient strength and stability to withstand the various forces encountered during operation, ensuring proper operation.
Guardians: These include blade guards and transmission guards. The blade guard prevents injury from the rotating blades and prevents debris from flying. The transmission guard protects the transmission components, preventing dust and debris from entering, thereby extending their service life.
Operating Principle: A disc mower is pulled forward by a tractor. The tractor's power output shaft transmits power to the mower's transmission system. The transmission system distributes power to the individual disc blades, causing them to rotate at high speeds.
The discs typically reach speeds of around 3,000 revolutions per minute, with blade tip linear speeds of approximately 288 kilometers per hour. The centrifugal force generated by the high-speed rotation of the blades generates a powerful cutting force, severing grass or weeds.
Performance and Features:
Efficient Mowing: Disc mowers offer high efficiency, capable of mowing large areas in a short period of time. It features a high mowing speed, typically capable of mowing 0.6-2 hectares per hour, significantly improving agricultural production efficiency.
Clean Cutting: The blades' stable rotation trajectory and precise adjustment of their distance from the ground ensure a clean cut, facilitating grass regrowth and subsequent harvesting.
Adaptable: The mower can adapt to varying terrain and grassland conditions, such as slopes, wet ground, and grass with obstacles. The spring or hydraulic suspension system allows the mower to automatically adjust to the undulations of the ground, maintaining a consistent cutting result.
Excellent Cutting Quality: The sharp blades rotate quickly, ensuring a clean, precise severing of grass and weeds without tearing or breaking, ensuring high-quality cutting that facilitates subsequent forage processing and utilization.
Application Scenarios
Pasture Management: Used for harvesting and trimming pasture grass, it quickly removes overgrown grass to provide fresh forage for livestock, while also promoting grass regrowth and growth, maintaining the ecological balance of the pasture.
Farmland Weed Removal: Weeds can be removed from farmland, reducing competition between weeds and crops for nutrients, water, and sunlight, reducing the incidence of pests and diseases, and creating a favorable environment for crop growth.
Urban Greening Maintenance: Disc mowers can be used to mow lawns in urban parks, squares, and roadside green belts, maintaining a neat and beautiful lawn and enhancing the city's greening.
Golf Course Turf Mowing: Golf courses have high requirements for turf quality and aesthetics. Disc mowers can precisely mow the lawn, ensuring a smooth and even surface that meets the requirements of golf courses.
