Abstract
Claims
1. A high efficiency energy saving wood splitting machine comprising a motor (1), a main frame (2), a driving shaft (4) and a handle (7), characterized in that: The motor (1) is fixedly mounted on the main frame (2). The drive shaft (4) is rotatably mounted on the main frame (2) through a bearing seat with bearings. Both ends of the drive shaft (4) are fixedly mounted with pulleys (3). A push rod seat (20) is slidably mounted on the main frame (2). The push rod seat (20) is connected to the drive shaft (4) through a push rod (5) connected to its rear end. The drive wheel (100) on the output shaft of the motor (1) is connected to the pulley (3) on the same side through a belt (22). The control handle (7) is rotatably mounted on the main frame (2) through a rotating shaft to control the back and forth sliding of the push rod seat (20). A chopping knife (8) is mounted on the main frame (2) opposite to the push rod seat (20). A rack (501) is provided on the lower side of the push rod (5), and a gear (401) is provided on the drive shaft (4) for meshing and transmission with the rack (501). A separation spring (23) is provided between the push rod seat (20) and the push rod (5). In the absence of external force, the elastic force of the separation spring (23) will separate the rack (501) and the gear (401). A pressure roller (6) for pressing the push rod (5) downward is installed on the main frame (2) coaxially with the control handle (7). A connecting spring (21) for flexible suspension connection is provided between the pressure roller (6) and the control handle (7). The bottom of the push rod seat (20) is equipped with multiple roller-type rolling devices (17) for sliding along the main frame (2). The motor (1) is a DC brushless intelligent variable frequency external rotor motor. The motor (1) is equipped with a motor-specific controller (10). The motor (1) is provided with a protective shell (11) and an emergency stop switch (12) is installed and connected. The motor (1) is connected to a plug (13) with leakage protection function.
2. A high efficiency energy saving wood splitting machine as claimed in claim 1 wherein: The main frame (2) is fixedly installed with a support leg (15) on the lower front side. The support leg (15) is made of bent metal tube. A hand-held part (1501) is bent upward at the lower part of the support leg (15). A wheel frame (14) is fixedly installed on the lower rear side of the main frame (2). Movable rollers (24) are installed at both ends of the wheel frame (14). The movable rollers (24) are equipped with a brake device (25).
3. A high efficiency energy saving wood splitting machine as claimed in claim 2 wherein: A folding worktable (26) is mounted on the main frame (2) via a shaft. A pin (27) is installed between the folding worktable (26) and the main frame (2). The folding worktable (26) is located in front of the chopping knife (8).
4. A high efficiency energy saving wood splitting machine as claimed in claim 3 wherein: The main frame (2) is rotatably mounted with a safety handle (19) for limiting the movement of the pressure roller (6), and the lower end of the safety handle (19) is provided with a limiting block for limiting the movement of the pressure roller (6).
5. A high-efficiency and energy-saving wood splitter according to claim 4, characterized in that: The lower end of the pressure roller (6) is provided with a pressure roller wheel (601) for driving the push rod (5) to move downward.
