Under the scorching sun in the farmland, old Zhang’s hand holding the shovel has already worn out blood blisters – this is already the third tool dug out today. This scene is gradually becoming history in rural China. With the accelerated process of agricultural mechanization, disc trencher with its unique operational advantages, is reshaping the traditional trenching mode of operation. In this article, we will analyze the technical characteristics of this revolutionary agricultural machine and reveal how its innovative design can improve agricultural productivity.
1, structural innovation: the core design of the disc opener
The core component of the disc opener is the special alloy casting of the opener disc. Unlike the traditional straight blade trencher, this 40-80cm diameter disc realizes different depths of trench excavation through the tilt angle adjustment mechanism (15-35° adjustable range). In a comparative test conducted by an agricultural machinery research institute in Shandong, the disc design saves up to 28% of energy consumption and improves furrow regularity by 40% compared to traditional knives.
The dual cylinder pressure system is another highlight of the equipment. By independently controlling the left and right side hydraulics, the operator can adjust the furrow depth (15-50cm) and width (20-60cm) in real time from the cab. This precise control capability is especially suitable for facility agriculture scenarios that require precise irrigation and drainage.
2、Performance breakthrough: analysis of three major operational advantages
Efficiency revolution: Take the common 1.2-meter furrowing operation as an example, manual labor can complete about 80 meters per day, while the disc trencher can complete 300-500 meters per hour. The actual application data of a grape planting base in Zhejiang shows that the cycle of trenching operation in 200 mu park has been shortened from 15 days to 3 days.
Quality leap: the unique disc rotary cutting mode (speed 150-300r/min) to form V-shaped grooves, groove bottom flatness error control within ± 2cm. This standardized groove not only facilitates irrigation and drainage, but also lays the foundation for subsequent seeding and fertilization processes.
Cost optimization: Although the purchase of equipment requires 30,000 to 80,000 yuan, but the comprehensive calculation of labor, time costs, in the average annual use of more than 50 times the scene, the payback period can be shortened to 2 years. The practice of a tea cooperative in Yunnan shows that the annual maintenance cost per mu of tea plantation drops by 120 yuan after using disc openers.
3, scene adaptation: selection strategy for different models
In response to the diverse needs, the mainstream models in the market can be divided into three categories:
Micro electric models (3-5kW): suitable for greenhouses, orchards and other small spaces, the standard 15cm ultra-thin body can easily pass through the 1.2m inter-shed channel
Medium hydraulic models (30-50 hp): matched with the use of conventional tractors, with a depth memory function, especially for terraces and other complex terrain
Large Intelligent Models (80 hp +): integrated GPS navigation and automatic leveling system, the operating precision of centimeters, suitable for ten thousand acres scale cm level, suitable for 10,000 mu level large-scale farms
The key purchase parameters should focus on the thickness of the wear layer of the disc (≥8mm is recommended), the pressure value of the hydraulic system (16-20MPa is preferred), and the integrity of the protection device. Jiangsu, a farm machinery dealer’s market feedback shows that models equipped with German Bosch hydraulic components failure rate is 60% lower than ordinary products.
4、Operation and maintenance points: the secret to extend the life of the equipment
Daily maintenance of the three-step method:
Clean the clay attached to the disc surface immediately after operation (high-pressure water gun is recommended)
Replenish the special gear oil every 50 hours (ISO VG220 standard)
Focus on checking the disc bearing clearance during the end-of-quarter overhaul (standard value of 0.05-0.1mm)
In the maintenance practice of a certain agricultural cooperative, the service life of the key components of the equipment with strict implementation of the maintenance protocol is extended by more than three times. For the common problem of disc bias wear, technicians recommend dynamic balance testing at the end of each season, and wear discs should be replaced in time when the deviation exceeds 15g-cm.
The retrofitting of intelligent warning system has become a new trend. Through the addition of vibration sensors and temperature monitoring module, bearing failure can be warned 30-50 hours in advance to avoid losses caused by sudden shutdown. After the introduction of this system in a modern agricultural park in Henan Province, equipment maintenance costs were reduced by 45%.
With the popularization of the concept of precision agriculture, disc openers are evolving in the direction of intelligence. The latest model has been equipped with a 5G remote control system and soil moisture sensing module, which can automatically optimize furrowing parameters according to real-time soil data. In a cotton planting base, this intelligent equipment has increased irrigation efficiency by 70% and reduced water waste by 35%.
