3MZ - 4 Four - power Cultivation and Earth - covering Machine

Multifunctional Expert for Potato Cultivation Management: Integrating Soil Loosening, Weeding, Earth - covering and Top - dressing

The 3MZ - 4 Four - power Cultivation and Earth - covering Machine is an agricultural machinery for potato cultivation and earth - covering. It can perform operations such as soil loosening, weeding, ridge - building, and top - dressing, and also has the functions of increasing soil temperature and conserving soil moisture.

Product Highlights

Four - row High - efficiency Operation—Completes soil loosening, weeding, earth - covering, and top - dressing at one time, with a 40% increase in efficiency.

Ridge Shape Optimization—Patented curved plow body creates a "narrow - top, wide - bottom, and bulging - middle" ridge for drought resistance and heat preservation.

All - terrain Adaptability—Suitable for both film - covered and open - field conditions, with significant advantages in cold regions.

Modular Design—Quickly replaceable components to achieve 8 functions such as cultivation, deep loosening, and ditch - opening.

Plow Body : Adopts a new curved surface structure, suitable for ridge - building operations in cold regions of the north, especially for the cultivation of tuber crops. The cross - section of the ridge (detail drawing) is small at the top, large at the bottom, and bulging in the middle. The outer shape of the ridge is smooth and neat (detail drawing), increasing the tuber - storing capacity of a single ridge. This ridge has the effects of drought resistance, soil moisture conservation, heat preservation, and yield increase.

Plow Wall : Adopts a curved surface design, making the force - bearing surface of the plow body more reasonable and reducing the operation resistance. The width of the bilateral plow walls is adjustable (detail drawing), which can control the size of the ridge. The lower part of the plow wall (detail drawing) is in a retracted form, ensuring that tubers will not be scratched during cultivation operations. At the same time, the ridge is tightly covered, making it difficult for tubers to be exposed, which is extremely beneficial to the growth and development of tubers.

By replacing different operation components, it can complete operations such as cultivation and weeding, deep loosening, top - dressing, earth - covering, and ditch - opening. It can operate on both film - covered and open - field land. Its row spacing, cultivation depth, and fertilizer application amount can be adjusted within a wide range. It has the characteristics of reasonable and sturdy structure, convenient operation and maintenance, reliable performance, and wide applicability.

Small Elastic Teeth

Consist of an S - shaped elastic shovel handle and a double - pointed soil - loosening shovel. They are mainly used to loosen the soil and remove weeds on both sides of the potato ridge, and their depth can be adjusted according to actual conditions.

Soil - loosening and Earth - covering Device

Consists of a shovel wing, shovel body, shovel tip, and shovel handle. It is mainly used to loosen the soil and cover the ridge crests on both sides with soil. The penetration depth of the shovel tip can be adjusted by adjusting the height of the shovel handle, and the penetration angle of the shovel can be changed by adjusting the position of the small bolt below. The earth - covering width, height, and amount can be adjusted by adjusting the angle of the shovel wing. The shovel tip has undergone heat treatment, with high strength, hardness, and wear resistance. The rigid connection method shown in the figure enables good soil - loosening effects even in hard soil.

Shaper

Consists of a shaping frame body, an arc - shaped downward - bending plate, a movable cover plate, and a blade protector. The arc - shaped downward - bending plate mainly makes the piled - up soil in an arc - shaped trapezoid, and this kind of ridge shape is plump with more soil, which is more conducive to the growth of potatoes. The width of the ridge can be adjusted by adjusting the opening size of the arc - shaped downward - bending plate. The height of the ridge can be adjusted by adjusting the pull rod. The blade protector has high strength, hardness, and wear resistance after heat treatment and plays a role in protecting the arc - shaped downward - bending plate from wear. After the potato seedlings emerge, the movable cover plate can be removed to prevent seedling damage.

Compression Spring Connecting Rod

Consists of a connecting frame, a compression spring, a connecting rod, and a stop sleeve. During operation, the compression spring exerts a downward pressure on the shaper to make its shaping more complete. When the machine needs to turn around or travel on the road, the connecting rod and stop sleeve prevent the shaper from descending. The height from the ground can be adjusted by adjusting the position of the hole on the rod.
