Product Description 4ULZ-170 potato
combine harvester can directly load potatoes into the truck,
simplifying the work flow and reducing the labor
intensity. The structure type is traction type. During work,
the tractor pulls the combine harvester and excavates the digging
shovel. At the same time, the potato-soil loosening and excavation
depth limit are carried out by the contour-shaped deep-wheel, and
the excavated potato soil is transported through the conveying net
sieve for potato-soil separation and potato block transportation.
In the process of potato tuber transport, the potato is separated,
the clean potato after the potato-soil, potato-salt separation
enters the potato transport device, and finally the clean potato is
transported to the transport vehicle through the potato transport
device, and the transport vehicle after the harvest is transported
away. 1. The separation effect of
soil and potatoes is good. The front floating disc knife is used to
cut the ground along both sides of the potato ridge together with
weeds, which is conducive to the excavation of parts and prevents
the stems and vines and weeds from winding and blocking on both
sides of the machine; The profiling suppression depth limiting
device not only crushes the hard shell on the soil surface of the
ridge body, makes the potato soil loose, and improves the
separation effect of potato soil. Moreover, it can ensure the depth
of digging shovel, dig potatoes fully without damaging potatoes,
and reduce power consumption. The two-stage wavy grid transport
separator is made of high-performance alloy steel through special
heat treatment process. It has the characteristics of good
elasticity, high strength, good wear resistance, etc., so that the
separation effect of potato and soil can reach the best, and the
sticky and sandy soil layers can be harvested. 2. Low
skin breaking rate: scientifically adjust different vibration
amplitude according to potato soil content and potato movement
track at different stages of transportation. The grid type
transportation separation device is mainly composed of toothed
tape, special steel grid, driving wheel, passive wheel and shaking
wheel. The driving wheel is a rubber tooth, which is well meshed
with the steel grid, with light wear, long service life, reliable
use, and less damage to potatoes, reducing the potato skin breaking
rate by less than 2%. 3. The effect of soil clearing
is good. The harvested potatoes enter the soil clearing and
seedling removing device after excavation and separation of potato
and soil. The rubber roller with special shape is used for counter
rotation to effectively remove the clay on the potato skin. The
seedling removing shaft pulls the potato seedlings away, making the
harvested potatoes cleaner. 4. High conveying
efficiency. The conveying arm is foldable and takes up less space.
The entire lifting conveying device is divided into continuous
U-shaped potato bags by a 20cm plastic mesh fence at an equal
distance. The potatoes will not roll during the lifting process. It
is more stable than the slope conveying device, with a larger
lifting angle and higher efficiency. The high-strength, perforated
and elastic mesh conveying device is used to further screen the
clay on the potato skin during the conveying process.
5. The machine runs quickly without vibration, grass blocking, soil
leakage and long service life. The earth angle of the digging
device is consistent with the lifting angle of the conveying and
separating device to solve the problem of soil accumulation after
shoveling; The whole machine adopts the laser cutting machine for
blanking, which is precise and beautiful, with high concentricity,
high-precision sealed bearings, abrasion resistant rubber wheels,
never entering the soil, and has a long service life. Detailed

Advantages The potato combine harvester
can realize the one-time excavation of potato, the separation of
potato-soil, the separation of potato-salt, centralized collection
and transportation, etc., and can harvest two ridges at a time, the
working efficiency is above 0.33 hm2/h, and the loss is small and
the skin breaking rate is low. Low, the potato is light and
contains less impurities. The structure mainly consists of a frame,
a depth limited wheel, a potato soil separation device, a clearing
and soil removing device, a non-equidistant potato collecting
device, a conveying device and a hydraulic system./* March 10, 2023
