This product is a two row and two row seedling killing machine, suitable for a ridge spacing of 900mm. It can complete the cutting and sorting of seedlings at once. By using potato machinery to kill seedlings, the surface of potato tubers is fully cork ified, making it easier to separate from stems and seedlings. The aging of the surface can also significantly reduce harvesting. This machine is easy to operate, has good seedling crushing effect, good reliability, high operating efficiency, and ensures the quality of commercial potatoes. The crushed stems and seedlings can be returned to the field, which can improve soil fertility. This potato seedling killing machine is suitable for cutting and killing potato seedlings before harvest with a ridge spacing of 90 centimeters, a ridge height between 15-30 centimeters, and a ridge circumference of no more than 110 centimeters. The soil moisture content should not exceed 25% during the operation, and it is recommended to operate at a speed of 4-7 kilometers per hour. This machine has been widely used in regions such as North China, Northeast China, and Northwest China.

Its specific innovative points include the following aspects:

1. Double helix technology of seedling killing knife:The seedling killing blades of the four row potato seedling killing machine are symmetrically distributed in a double helix on the seedling killing axis. There are 5 different shapes of seedling killing blades, with varying lengths. The blade is connected to the seedling killing shaft in a single way. When one of the seedling killing blades is damaged or severely worn, it can be replaced separately. It is easy to adjust and maintain, and the movement trajectory of the seedling killing blade is basically consistent with the ridge shape, ensuring the crushing effect. Cutting off the seedlings and weeds in the potato field is beneficial for the later harvest of potatoes.
2. Ground wheel adjustment technology:The height between the seedling killing machine and the ground can be adjusted through the adjustment handle on the ground wheel, which can be adjusted appropriately according to the planting characteristics of different regions, improving the regional adaptability of the whole machine.
3. Diversion baffle technology:The diversion baffle runs along the top of the potato ridge, diverting the cut seedlings and weeds to the furrows on both sides, which is beneficial for later harvesting by the harvester.
4. Anti reverse overrunning clutch device:The device is embedded inside the gearbox output shaft, preventing the blades from rotating in the opposite direction, ensuring that the components are not easily damaged, and also protecting the gearbox and rear output shaft. Reduced the failure rate of the machine.

Kill seedling knife
The seedling killing knife is symmetrically distributed in a double helix on the seedling killing axis, consisting of five types of blades: long straight blade, long curved blade, medium curved blade, oblique blade, and short straight blade. It is arranged according to the characteristics of the potato ridge, using short straight blade at the top of the potato ridge, oblique blade and curved blade at the slopes on both sides of the potato ridge, and long blade at the bottom of the ditch of the potato ridge. This arrangement can achieve good cutting effect. The rotation of the seedling killing knife cuts the edge in the direction of the seedling, making it easier to cut the seedlings. Cutting off the seedlings and weeds in the potato field is beneficial for the later harvest of potatoes.

drive
The tractor transmits power to the gearbox through the drive shaft, and the gearbox transmits power to the large pulleys on both sides through the left and right drive shafts. The large pulley transmits power to the small pulley through the belt, and the small pulley drives the seedling killing shaft to kill the seedlings.

Diversion baffle
The diversion baffle runs along the top of the potato ridge, diverting the cut seedlings and weeds to the two side ridges, which is beneficial for the later harvesting of the harvester.
