The Ministry of Industry and Information Technology has published a list of enterprises (second batch) that meet the "Access Conditions for Tire Renovation Industry" and "Entry Requirements for Comprehensive Utilization of Waste Tires". There are many types of tractors, such as two-wheel (walking tractor) and four-wheel. It is divided into rear-wheel drive and four-wheel drive. Four-Wheel Farm Tractor,Mini Four-Wheel Farm Tractor,Diesel Engine Four-Wheel Farm Tractor,Four-Wheel Agriculture Tractor Zhengzhou Dongfeng Mid-south Enterprise Co., Ltd. , https://www.cn-dfmtruck.com
The enterprises that meet the entry requirements include Tangshan Xingyu Rubber & Plastic Industry Co., Ltd., which is mainly engaged in recycled rubber, Tangshan Tianyuan Rubber Factory, and Liyang Jiasheng Renewable Resources Co., Ltd.; the main business is Lianyungang Qiangshun, which is refurbished by tires. Rubber Products Co., Ltd., Gaotang Xinglu-Benda Tire Strengthening Co., Ltd., Qingdao Minglong Industry and Trade Co., Ltd., Sichuan Meishan Traffic Fatigue Factory; Shandong Zouping Kaiyuan Chemical Stone Co., Ltd., the main business of thermal cracking; main business Binzhou Fenghua Rubber Powder Manufacturing Co., Ltd. is a rubber powder.
High horsepower wheeled tractor has better traction performance, suitable for high-speed operation of large farms equipped with wide-width agricultural tools.
Mainly includes engine, chassis, electrical equipment. The chassis includes a transmission system, a steering system, a walking system, a braking system, and a working device.
The tractor can drive by the power of the internal combustion engine through the transmission system, so that the driving wheel obtains the driving torque Mk, and the driving wheel that obtains the driving torque gives the ground a small, backward horizontal force (tangential force) through the tire pattern and tire surface, and the ground Facing the horizontal rice force Pk with the same driving force and opposite direction, this Pk reaction force is the driving force (also called feeding propulsion) that drives the tractor forward. When the driving force Pk is sufficient to overcome the forward rolling resistance of the front and rear wheels and the traction resistance of the farm implement, the tractor will move forward. If the driving wheel is lifted off the ground, that is, the driving force Pk is equal to zero, the driving wheel can only be idling in place, and the tractor cannot drive; if the sum of rolling resistance and traction resistance is greater than the driving force Pk, the tractor cannot drive. It can be seen that the driving of the wheeled tractor is achieved by the interaction between the driving torque driving wheel and the ground, and the driving force is greater than the sum of rolling resistance and traction resistance
