Solution Overview
Problem
Existing firewood splitting machines are inefficient and economically unviable due to high energy consumption and bulkiness, especially when equipped with multiple blades or tandem hydraulic systems, which complicates transportation and increases costs.
Innovation Solution
A hydraulically operated single-phase firewood splitting machine with an improved hydraulic cylinder integrated within a framework, featuring a tubular casing, piston, and non-return valve system that accelerates the operational stroke by controlling hydraulic media flow between chambers, reducing the need for extensive reconstruction or additional expenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple blades are used in the splitting tool, then the productivity of the machine is improved, but the device complexity and weight increase
Solution Approach 1:
The patent divides the splitting function into multiple independent blades (at least two blades) arranged side by side on the splitting tool. Each blade can independently split timber sections, allowing the machine to process multiple pieces of firewood in sequence during a single operational cycle. This segmentation of the splitting function directly improves productivity while keeping each individual blade relatively simple in design.
2Productivity
If tandem hydraulic cylinders are used, then the productivity is improved, but the weight and dimensions of the machine increase
Solution Approach 1:
The patent combines multiple blades on a single splitting tool that is actuated by one hydraulic cylinder. Instead of using separate hydraulic cylinders for each blade (tandem system), the invention merges the splitting function into multiple blades that work sequentially during one operational stroke. This reduces the number of hydraulic cylinders from two to one, thereby reducing the machine's weight and dimensions while maintaining improved productivity through the multi-blade configuration.
3Productivity
If multiple blades are used, then the productivity is improved, but the energy consumption increases
Solution Approach 1:
The patent enables continuous useful action by having multiple blades on a single splitting tool that process timber sections in sequence during one operational stroke. The hydraulic cylinder drives the splitting tool with multiple blades through the timber sections continuously, eliminating the need for multiple separate hydraulic cycles. This continuous processing improves productivity while optimizing energy consumption by utilizing one hydraulic system rather than multiple independent systems.

AI summary
The invention refers to a firewood splitting machine with improved efficiency of a hydraulic cylinder (1) which is integrated within appropriate framework and adapted for pushing each section of a timber along a suitable guide towards a splitting tool. A first hydraulic connector (21) in the head (12) of the cylinder (1) is arranged along the central axis of said head (12) and comprises a protrusion (210), which extends in a direction towards the interior of the cylinder (1) and also protrudes into said cylinder (1), and at least one aperture (211) suitable for flowing the hydraulic media there-through is arranged adjacent to said protrusion (210). A piston (13) is furnished with a non-return valve (5), which is arranged on its front surface, which is faced towards the head (12), and which is on its side, which is faced towards the head (12), furnished with a first opening (51), which is adapted to cooperate with an elastically supported shutoff member (53), and on its opposite side with a second opening (52), which is hydraulically connected with a passage (54), which extends throughout the piston (13) and the rod (14) and enables said hydraulic media to flow towards said second chamber (32) between the rod (14) and the casing (11) of the cylinder (1). In the terminal position of the piston (13) closely to the head (12) or just adjacent to the head (12), said protrusion (210) within the first hydraulic connector (21) on the head (12) is located within said non-return valve (5), the elastically supported shutoff member (52) is in such case rest on said protrusion (210) against the force generated by a corresponding spring (53'), by which the hydraulic media is allowed to flow from the first hydraulic chamber (31) through said non-return valve (5) as well as through the piston (13) and the rod (14) towards the second hydraulic chamber (32).
