Hanwo brand 4YZ-4B corn harvester

Hanwo 4YZ-4B Plate Cutting Platform Corn Machine

Main technical features

lLower losses:

① Add high baffles to the left and right protective covers of the cutting table to prevent rod loss during high-speed operation;

② Add rubber barriers between the peeling machine and the grain silo to prevent grain loss on both sides of the peeling machine;

③ The rubber strip fed into the cutting platform has been upgraded to a chain+sprocket+wear-resistant rubber block structure, which improves the service life of the feeding chain and reduces the impact of the feeding teeth on the corn cob,

lReduce grain loss;

④ The spacing between the stem pulling plates can be adjusted quickly, conveniently and quickly, reducing rod breakage and grain loss;

⑤ Adopting 5 sets of adjustable high and low rollers and flat rollers dual-use peeling machines, the harvesting of green stems adopts high and low rollers to improve the peeling rate; When harvesting yellow and dry stems, adjust to flat rollers to reduce grain loss;

⑥ The speed of the throwing roller is increased, and the throwing rubber plate is widened to improve the throwing capacity and prevent corn stalks from accumulating in the front of the grain bin, resulting in rod dropping and grain loss during unloading.

lHigher efficiency:

① Matched with Yuchai/Weichai 240 and 260 horsepower six cylinder National IV engines, with greater reserve torque and higher harvesting efficiency;

② Adopting a three-stage system of front suction, middle stem pulling, and rear suction for impurity removal, the process is smooth, unobstructed, and suitable for all stages of corn harvesting;

③ The blade of the field returning machine is lengthened, the rotation diameter of the blade shaft is increased, and the diameter of the pulley is increased, which can better meet the requirements of the field returning effect during high-speed operation;

④ Optional grain lifting device (grain entering grain silo or vertical silo) can be installed to save unloading time, improve operation time and efficiency;

⑤ Optional secondary elevated grain silo to meet the unloading needs of high rail transport vehicles;

⑥ Optional 500L large fuel tank, one refueling, worry free all day long.

lHigher reliability

① Adopting a static hydraulic walking system, with one pump and one motor, and a large displacement pump（90), with greater driving torque and stronger ability to get out of trouble;

② Adopting a three speed increased gearbox, increased side reduced gearbox, and reinforced rear axle, the operating speed can reach 15Km/hThe transition speed can reach46Km/h; Supporting facilities16Mn rectangular tube frame, chassis walking system moving towards zero faults;

③ The rubber strip fed into the cutting platform has been upgraded to a chain+sprocket+wear-resistant rubber block structure, which improves the service life of the feeding chain and reduces the impact of the feeding teeth on the corn cob, thereby reducing grain loss;

④ The main drive of the cutting table has been upgraded from three single belts to one triple toothed belt, increasing the torque transmission capacity by 30%;

⑤ The field returning machine has been upgraded to two double toothed belt drives to prevent belt rolling, increase bearing size, and improve the reliability of the tensioning system;

⑥ The crushing of bracts is achieved through high-speed transmission, upgraded from a chain to a belt transmission, while further increasing the speed of bracts crushing, resulting in smoother and more stable and reliable skin removal;

lMore comfortable driving experience

① Homework level II and transition level III are located on the seat follow-up armrest box, providing more user-friendly operation;

② Wide body air conditioning luxury cabin, dust prevention, sound insulation, shock absorption have been further improved, and the original air conditioning has been rearranged and upgraded for better results;

③ Optimize the instrument position to the left side of the cab and increase the display of the speedometer; 360 ° wiper; The driver's left foot and the front of the passenger seat are designed with foot pedals, making driving safer and more comfortable;

④ Add an air horn to the lower part of the driver's cab while retaining an electric horn for easy use by the operator in different scenarios;

⑤ Add one LED lighting on each side of the machine to meet the needs of night work.

lMore convenient maintenance

① The addition of support rods to the cover of the cutting table makes maintenance and upkeep more convenient;

② The whole machine is equipped with a chain automatic lubrication pump as standard, and optional butter automatic lubrication for easier maintenance;

③ Open the protective cover at a large angle on both sides and remove the small protective cover of the peeling machine transmission for easier inspection and maintenance.
