Skip Emptying Device Pivoting to Prevent Concrete Splashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dumpers used for transporting liquid concrete often result in splashing and soiling due to the high pouring edge, and existing solutions like a linearly movable chute fail to prevent soiling when the skip is pivoted up, as the chute front dips into emptied concrete.
Innovation Solution
A skip apparatus with a pivotable emptying device guided by a defined mechanism, where the emptying device pivots opposite to the skip during its upward movement, ensuring the outlet side remains elevated and focused, reducing splashing and soiling by maintaining a controlled flow of material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the pouring edge is positioned high above the ground, then the skip structure is simplified and easier to manufacture, but the concrete splashes when it hits the ground causing soiling
Solution Approach 1:
The emptying device acts as an intermediary element between the skip and the ground. It receives the poured concrete from the skip and guides it to the ground, preventing direct impact and splashing. The device includes a receiving area that catches the concrete and a controlled discharge mechanism that releases it gently to the ground surface.
2Length of moving object
If a linearly movable chute is used to extend the skip, then the pouring distance is increased, but the chute front dips into the emptied concrete when the skip is pivoted up
Solution Approach 1:
The emptying device is designed to be dynamically adjustable relative to the skip. It can pivot and change its position independently of the skip's movement, allowing it to maintain an optimal angle and distance from the ground throughout the pouring process. This dynamic adjustment prevents the front edge from dipping into the emptied concrete.
Solution Approach 2:
The emptying device is separated from the skip as an independent component with its own movement and positioning system. This segmentation allows the emptying device to be controlled separately from the skip, enabling it to maintain the correct position and angle while the skip is being filled and emptied, preventing contact with the poured concrete.
3Object-generated harmful factors
If the emptying device outlet is positioned low to reduce splashing, then soiling is minimized, but the outlet may penetrate into already cast concrete
Solution Approach 1:
The emptying device incorporates sensors and control mechanisms that provide feedback about the position of the outlet relative to the poured concrete. When the outlet approaches the surface of the emptied concrete, the system automatically adjusts the outlet position or the pouring rate to prevent penetration, ensuring the outlet remains just above the concrete surface.
Solution Approach 2:
The emptying device allows for dynamic changes in pouring parameters such as flow rate, outlet position, and outlet angle. By adjusting these parameters in real-time based on the pouring progress, the system maintains optimal conditions that prevent both splashing and outlet penetration into the concrete.

AI summary
A skip apparatus for a working vehicle has a skip that is pivotable upward about a carrying axle and that has a pouring edge via which pourable material is able to be poured out of the skip. The skip apparatus additionally has an emptying device which is pivotable relative to the skip about a pivot axle on the skip during a pivoting movement. The emptying device has an inlet side and an outlet side. The inlet side is arranged in a region of the pouring edge such that the pourable material, which is poured out of the skip via the pouring edge, passes into the emptying device via the inlet side. The pivoting movement of the emptying device is guided in a defined manner by a guiding device. A working vehicle having such a skip apparatus also is provided.
