Seed Boot Stabilizer Mounting for Air Seeder Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seed boot mounting systems for air seeders suffer from significant wear due to ground contact, making replacement expensive and challenging, especially when bores become worn or misshapen, and existing solutions require bore enlargement which is not always feasible.
Innovation Solution
A seed boot stabilizer is introduced that fits between the seed boot and base mount, using a fastener structure through aligned bores to stabilize the seed boot without requiring enlargement of existing bores, thereby reducing wear on the base mount and allowing for easy replacement of the seed boot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the seed boot is directly mounted to the base mount using a pin through ears, then the mounting structure is simple and allows for easy replacement, but the base mount ears are subject to significant wear over a planting season
Solution Approach 1:
The invention divides the mounting system into three separate components: the base mount ears, the stabilizer, and the boot ears. The stabilizer acts as an intermediate segment that absorbs wear from the pin rotation, preventing direct wear on the base mount ears. This segmentation allows the boot to be easily replaced while protecting the permanent base mount structure.
Solution Approach 2:
The stabilizer serves as an intermediary component between the base mount ears and the boot ears. It mediates the wear caused by pin rotation and boot movement, protecting the base mount ears from direct contact and wear. The stabilizer can be replaced or adjusted without affecting the base mount structure.
2Adaptability or versatility
If the base mount ears are enlarged to accommodate worn bores, then the boot can be remounted, but this requires complex rebuilding procedures and is not easily accomplished
Solution Approach 1:
The stabilizer is designed as a replaceable component that can be easily replaced when worn, rather than requiring enlargement or repair of the permanent base mount ears. This disposable approach to the stabilizer protects the valuable base mount structure from complex repair procedures.
Solution Approach 2:
The stabilizer is pre-installed on the base mount ears before the boot is attached. This preliminary action protects the base mount ears from wear during operation, eliminating the need for subsequent enlargement or repair procedures.
3Object-affected harmful factors
If the seed boot is allowed to pivot during operation, then the boot can accommodate ground contact forces, but this pivot movement causes wear on the mounting holes
Solution Approach 1:
The stabilizer acts as an intermediary that allows the boot to pivot and accommodate ground contact forces while protecting the base mount ears from wear. The stabilizer absorbs the rotational wear, enabling the boot to maintain its ability to handle ground contact stresses.
Solution Approach 2:
The mounting system is segmented into wear-prone components (stabilizer, boot ears) and permanent components (base mount ears). This segmentation allows the pivot movement and associated wear to occur in replaceable components rather than in the permanent base mount structure.

AI summary
A system comprising an air seeder assembly has a base mount with base ears including a first pair of base bores and defining a channel therebetween with a channel width. The assembly comprising a seed boot removably mountable on the base mount, and having a pair of boot ears with a first pair of boot bores. A seed boot stabilizer is mountable on the seed boot and the base mount and positionable in the channel between the seed boot and the base mount. The boot stabilizer has a primary portion with a first stabilizer bore alignable with the first pair of base bores in the base ears. A fastener structure may extending through the pair of base bores of the base ears, the pair of boot bores of the boot ears and the stabilizer bore to fasten the stabilizer to the seed boot and the base mount.
