Agricultural Pick-Up Prong with Transport Concavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pick-up devices for agricultural products like grass, straw, and leguminous materials tend to accumulate these products against the bands during transport, leading to infiltration into the driving system area, causing dirtiness and difficulty in unloading.
Innovation Solution
The pick-up device features long-limbed prongs with a holding and transport concavity that directs the product away from the bands, preventing infiltration and facilitating easy unloading by maintaining the product within a concavity during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pick up elements use straight prongs with bands surrounding the preferential direction of development, then the agricultural product can be lifted and transported, but the product accumulates against the bands during transport
Solution Approach 1:
The prongs are given a curved shape instead of being straight, with the development line forming a concavity that faces the bands. This curvature allows the product to be contained within the concavity during transport, preventing accumulation against the bands while maintaining effective lifting and transport capability.
2Reliability
If bands are placed side by side to cover the driving system, then the agricultural product is prevented from falling inside during transport, but the product infiltrates into the space between bands
Solution Approach 1:
The curved development line of the prong creates a concavity that acts as a containment structure. This concavity faces the bands and keeps the product contained within the prong's curvature during transport, preventing infiltration into the space between bands and protecting the driving system area from product accumulation.
3Productivity
If the transport zone is a straight segment perpendicular to the covering surface, then the product can be transported efficiently, but unloading becomes difficult due to product accumulation
Solution Approach 1:
The curved development line creates a concavity that facilitates product unloading. As the pick up element moves through its closed trajectory, the product naturally accumulates in the concavity and can be easily discharged by tilting or opening the pick up element, solving the unloading difficulty while maintaining transport efficiency.

AI summary
A pick up element (1) for agricultural products having a thin and long-limbed shape such as grass, straw, leguminous and similar products comprises long-limbed pick up prongs (10) developing along a development line (11) between a first and a second end (110,111) and ideally divided, along the development line (11) into: a taking up zone (100) of the agricultural products from the ground comprising the first end (110); a transport zone (101) of the agricultural products consecutive to the taking up zone (100) wherein the development line (11) defines a holding and transport concavity (112) of the agricultural products; a hooking zone (102) consecutive to the transport zone (101) and comprising the second end (111). A pick up device (2) comprises a plurality of said pick up elements (1) for agricultural products moved by a driving system (21) each along a closed trajectory with the transport concavities (112) turned towards the same direction (116) of movement of the prongs (10), and inclined with respect to bands (22) placed side by side so that during the motion of the prongs (10) along a transport segment of the closed trajectory the agricultural product tends to move away from the bands (22) and to accumulate in the holding and transport concavity (112), facilitating the release of the agricultural product from the prongs (10) at the release point.
