4u-2 1390-2 traction potato combine harveste

  4u-2 1390-2 traction potato combine harvester is mainly suitable for harvesting underground rhizome crops such as potato, carrot, green radish, garlic, onion, sugar beet, sweet potato, peanut, horseradish, potato and taro
It is mainly used to harvest potato (potato)
It is a potato digging and harvesting machine matched with 48-120 HP wheeled tractor
Main features: 1) 4u-2 1390-2 traction potato combine harvester adopts simple and light frame structure, reasonable design, convenient installation, good adjustability, wide adaptability, convenient operation, flexible use, good harvester performance, low potato damage rate, no injury to potato skin, no peeling, no loss of potato, and low fruit drop rate
Potatoes are laid neatly and have a high rate of bright potatoes
They can be harvested with potato seedlings
Special steel is used for a long time
The whole machine is beautiful and generous
Net income ratio is greater than 99% , The skin breaking rate is less than 1% , 2)  The potato excavator adopts the design that the soil entry angle of the excavation device is consistent with the lifting angle of the conveying and separation device, which effectively solves the problem of soil accumulation after shoveling; 3)  4u-2 1390-2 traction potato combine harvester adopts traveling depth limiting mechanism to effectively reduce resistance and improve operation smoothness; 4) The potato excavator operates quickly without vibration, blocking soil and grass, leaking soil quickly, shaking soil clean and working smoothly, 5) 4u-2 1390-2 traction potato combine harvester can directly extract the residual agricultural film in the soil, and the residual film can be recycled clean without affecting the growth of crops in the next quarter
6) The potato combine harvester can be driven by a 48-120 HP tractor, which is suitable for the four-wheel tractor owned by most farmers at this stage
It has the characteristics of wide matching power, less investment and fast efficiency
Scope of application: This product is suitable for potato harvest with ridge planting
The soil type is medium loam and sandy loam, and the soil moisture content is 10 ~ 20%
Beyond the above range, the operating performance of the product may change, and all kinds of soil can be used The machine harvests sweet potato about 5 mu - 20 mu per hour

The 4U series potato combine harvester is matched with a 25-120 HP tractor through the rear transmission shaft as the power transmission mode
The potato is separated from the soil by the excavator, so that the potato can be picked up from the potato root
The working principle is that under the transmission of tractor transmission shaft, hoe shovel type excavation mechanism, grid mesh chain and vibrating screen type conveying separation mechanism are adopted
The 4u-2 1390-2 traction potato combine harvester separates the soil and potato tubers through the vibration of the vibrating screen, the soil blocks and soil surface in the soil fall in the gap of the vibrating screen, and the potatoes left on the vibrating screen fall on the land behind through the vibration of the vibrating screen
Potato excavator is mainly composed of suspension connecting device, frame assembly, hoe and shovel device, grid chain and vibrating screen conveying and separation device

  Maintenance and storage
After each shift, the soil at each part of the potato combine harvester shall be removed
2
Check the fasteners of all parts and fasten them in time if they are loose
3
Check whether the rotating parts of the potato combine harvester rotate flexibly
If they are abnormal, they should be adjusted and eliminated in time
4
When not in use for a long time, the potato combine harvester shall be protected from rain and contact with acidic substances to avoid corrosion
The blade should be oiled!
