AI Technical Summary

Technical Problem

Existing orchard hole diggers are difficult to level precisely on sloping ground, resulting in poor hole-digging results, especially in hilly and mountainous areas with complex terrain, where the verticality of the hole-digging blades cannot be guaranteed.

Method used

The hole-digging mechanism is installed using a three-point suspension mechanism, and five horizontal sensors are installed on the tool mounting plate. Combined with the control system, the verticality and position of the hole-digging tool are automatically adjusted. The reverse-rotating hole-digging tool achieves dynamic balance and overcomes chatter resistance, thus protecting the equipment.

Benefits of technology

It enables precise vertical digging on sloping ground, improving drilling efficiency, protecting equipment from damage, and enhancing the automation and precision of operations.

Abstract

This invention proposes a double-hole hole-digging system and control method for orchards. The system includes a frame and a hole-digging mechanism. The hole-digging mechanism includes a tool mounting plate, with hole-digging tools and tool driving devices for rotating the tools at both ends. A level sensor is installed at each of the four corners and the center point of the vertical surface of the tool mounting plate. A three-point suspension mechanism is mounted on the frame, and the tool mounting plate is hinged to this mechanism, allowing for level adjustment. This invention enables automatic positioning and precise hole-digging, ensuring the hole-digging tools cut vertically and apply force during the hole-digging process, significantly improving hole-digging efficiency.
