When working in orchards, greenhouses, and densely planted economic crop fields, traditional fixed chassis small excavators have a fixed body width. When encountering narrow spaces between fruit trees and narrow corridors in the greenhouse area, they are prone to scratching branches, crushing seedlings and crop roots, which not only damages the planted crops but also causes unnecessary agricultural losses.
This has always been a major pain point in the mechanization of fruit and vegetable planting operations. In response to the difficulties of working in narrow fields, a new agricultural small excavator equipped with a retractable chassis has been officially launched on the market.
The body structure has been optimized to adapt to the refined farming scene in the field, completely solving the problems of easy seedling pressure, root damage, and restricted passage in narrow construction.
The core highlight of this agricultural excavator is that the track chassis supports free telescopic adjustment, and the body width can be flexibly adjusted according to the field aisle and fruit tree row spacing. After the chassis is folded and contracted, the body of the machine becomes significantly narrower, making it easy to enter narrow work areas such as greenhouse narrow passages, dwarf dense planting orchards, nursery seedlings, and vegetable garden ridges. It can turn and turn flexibly without scratching fruit tree trunks, vines, branches, and leaves;
When it is necessary to level the ground and carry out heavy excavation operations, the chassis can be extended and widened outward to increase the support span of the tracks.
This significantly improves the stability of the entire machine, makes the excavation force more stable, and reduces the risk of overturning during the operation process. It also meets the two major requirements of narrow ground passage and operation safety.
Different from the drawbacks of ordinary excavators, such as non adjustable chassis, easy crushing of seedling plastic film when entering the ground, and damage to soil ridges and ditches, the retractable chassis design allows the equipment to accurately fit the planting ridge distance for agricultural operations such as digging trenches, fertilizing, opening channels and drainage, digging pits for seedlings, loosening soil and turning over the ground, clearing gardens and weeding. The ground contact area of the track is uniform, the ground pressure is small, and it moves narrowly after contraction. The walking trajectory is controllable, avoiding crop roots and seedlings to the greatest extent possible, reducing crop damage caused by mechanical entry into the ground from the root, and lowering the cost of field management and maintenance for growers.
The overall size of the model is compact and lightweight, suitable for mainstream agricultural micro digging specifications ranging from 1 ton to 1.8 tons. In addition to a telescopic chassis, it can be equipped with a complete set of accessories such as standard digging buckets, breaking hammers, rotary drills, and wooden grabbing tools.
One device can handle multiple tasks such as orchard fertilization and trenching, greenhouse land renovation, mountain land reclamation, channel dredging, seedling planting and drilling, and hardened ground crushing.
The device has a low threshold for operation, and farmers can easily get started with simple teaching. It is easy to transfer and small trucks can transport cross plot operations.
According to feedback from purchasing growers, in the past, using ordinary small machinery to enter the garden would cause a lot of losses every year due to the machine body being too wide, hitting fruit trees, and crushing vegetable seedlings. This retractable chassis small excavator can narrow the machine body and operate along the rows without the need for manual widening of the aisle in advance, eliminating the need for manual land modification processes. The efficiency of the operation is several times higher than that of manual labor, and the damage rate of seedlings is significantly reduced.
Industry agricultural machinery R&D personnel stated that the scalable and adjustable chassis is an important technological upgrade for agricultural micro excavators to adapt to segmented agricultural scenarios. It closely follows the development direction of intensive orchard planting and refined management of facility agriculture, and solves the industry contradiction of "too wide to enter, too narrow to be stable" for small agricultural machinery.
In the future, this series of models will continue to optimize their power and structural configuration, relying on sufficient stock to ensure fast delivery, helping farmers reduce labor, energy consumption, and increase production capacity with mechanized tools, and promoting the upgrading of fruit and vegetable planting mechanization towards finer and more suitable for actual field conditions.
