Combine Controller Layout Between Cooling and Dust Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combine designs face challenges in protecting the electric controller from both heat generated by the engine and dust accumulation, particularly due to its proximity to the reaping unit, which can lead to electrical troubles.
Innovation Solution
The electric controller is strategically positioned on the side surface of a cooling device, such as an intercooler or radiator, which is supported by a frame on the traveling machine body, keeping it away from direct engine heat and dust, with the cooling device and grain tank interposed to create a stable temperature and clean environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the electric controller is arranged on the front side of the shielding member to reduce heat transmission from the engine, then thermal damage risk is reduced, but the electric controller becomes susceptible to dust accumulation from the reaping unit
Solution Approach 1:
The cooling device serves as an intermediary barrier between the electric controller and the harmful environments (heat and dust). By positioning the electric controller on the side surface of the cooling device, the cooling device structure itself acts as a protective mediator that blocks direct exposure to both engine heat and reaping unit dust, resolving the contradiction between thermal protection and dust protection.
2Reliability
If the electric controller is positioned away from the engine to avoid heat influence, then thermal stability is improved, but the controller may be exposed to dust from the reaping operation
Solution Approach 1:
Instead of positioning the electric controller only in the front-rear direction relative to the engine, the invention utilizes the lateral dimension by arranging the controller on the side surface of the cooling device. This dimensional shift allows the controller to be simultaneously远离 from engine heat while protected from dust by the cooling device's structure, achieving both thermal stability and dust protection.

AI summary
[Problem] To provide a combine in which an electric controller that controls operation of the combine is arranged at a location where the electric controller is less susceptible to heat generated from an engine and dust and the like are less likely to be accumulated, so that occurrence of a trouble in the controller can be prevented. [Solution] A combine is a combine in which an engine is arranged at a front portion of a traveling machine body. The combine includes a cooling device that cools the engine, and an electric controller that controls operation of the combine is arranged on one side surface of the cooling device.
