Bucket Tooth Side Access Hole for Construction Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bucket tooth replacement on construction vehicles is difficult due to narrow space requirements, making the process cumbersome and time-consuming.
Innovation Solution
The design features a bucket tooth with a through-hole that is shaped like a truncated and rotated cone, allowing access from the side for easier attachment and removal, and includes a concave opening for dirt removal, facilitating the replacement process.

If the groove is disposed to the rear of the tooth-side end and inclined outward, then the tooth structure is compact, but the space required for tooth replacement work becomes extremely narrow
Solution Approach 1:
The through-hole is positioned on the side wall of the tooth rather than at the rear end, changing the spatial dimension of access. This allows the locking member to be accessed from the side of the tooth, opening up the working space for replacement operations while maintaining the compact tooth structure.
Solution Approach 2:
The through-hole is positioned asymmetrically on the side wall rather than centrally or at the rear, creating an optimized access path. This asymmetric positioning allows tool access from the front side of the tooth, providing sufficient working space while maintaining structural compactness.
2Ease of operation
If the through-hole is positioned to allow side access, then replacement work becomes easier, but the tooth structure becomes more complex
Solution Approach 1:
The tooth structure is segmented into distinct functional zones: the through-hole is separated from the cavity, and the locking member is positioned within the through-hole rather than integrated into the cavity structure. This segmentation allows for easier access during replacement while keeping each component relatively simple.
Solution Approach 2:
The side wall positioning of the through-hole acts as an intermediary structure that facilitates access to the locking member. By placing the through-hole on the side wall rather than directly exposing the locking member, the design provides a simple access path without adding complex mechanisms.
3Ease of operation
If the through-hole is shaped like a truncated and rotated cone, then access space is enlarged, but manufacturing precision requirements increase
Solution Approach 1:
The through-hole is designed with specific geometric parameters (truncated and rotated cone shape) that optimize access space. The rotational axis is positioned at a specific angle (45 degrees) relative to the tooth width direction, and the hole is cut at a specific depth, creating the optimal access path while remaining manufacturable with standard machining operations.

AI summary
A bucket tooth for a construction vehicle includes a through-hole formed in a side wall part and passing through to a cavity. The through-hole has on a cavity side a rotating body hole having a shape of a truncated and rotated cone that remains after removing a large diameter side portion obtained by cutting diagonally to a rotational axis of the truncated and rotated cone with a large diameter side of the truncated and rotated cone being disposed on the cavity side, and with the rotational axis of the truncated and rotated cone being inclined outwardly toward the distal end portion of the bucket tooth from the cavity along a width direction of the bucket tooth.
