This application relates to a lithium-ion battery-powered rack and pinion wood splitter, belonging to the field of wood processing machinery technology. The wood splitter includes a frame, a fixed cutter head, a slide rail, a movable base, a power drive assembly including a motor, and a transmission mechanism. The fixed cutter head and slide rail are mounted on the frame, and the movable base is slidably mounted on the slide rail. The transmission mechanism includes a gear driven by the motor and a rack meshing with the gear; the output end of the rack is hinged to the movable base via a hinge shaft. Furthermore, it is equipped with a rack limit guide wheel that rolls against the smooth surface of the rack, a stroke control assembly for power-off linkage, and a lithium-ion battery pack. This invention utilizes the hinge structure to release the lateral load stress generated during wood splitting, combined with the guide wheel's forced constraint to prevent tooth skipping, and uses mechanical triggering to achieve power-off at the limit stroke, effectively improving the stability of the heavy-duty transmission system and the safety of equipment operation. Moreover, the overall structure is compact, free from cable constraints, and convenient for outdoor mobile operation.

A bidirectional high-speed oil cylinder and a log splitter. The bidirectional high-speed oil cylinder comprises a hydraulic oil cylinder body (41); a large piston (42), which is slidably arranged in the hydraulic oil cylinder body and divides an inner cavity of the hydraulic oil cylinder body into a rod cavity (45) and a rodless cavity (46); and a piston rod (43), which is telescopically mounted on the hydraulic oil cylinder body, an end of the piston rod extending into the rod cavity and being connected to the large piston. A hydraulic control check valve (47) on the large piston automatically opens and closes according to different working conditions of the bidirectional high-speed oil cylinder when the piston rod performs a reciprocating operation, such that hydraulic oil in the rod cavity and in the rodless cavity automatically compensates for each other; and the bidirectional high-speed oil cylinder makes the piston rod rapidly reciprocate during light-load or no-load operation, and generates a huge thrust equivalent to that of a traditional oil cylinder during a heavy-load operation, thereby improving the working efficiency of a log splitter, and reducing the energy consumption of a hydraulic system.

This invention relates to a wood splitter, comprising a frame, an oil tank connected to the frame, tires mounted on both sides of the oil tank, and a foot support connected to the other end of the frame; an engine and a gear pump are also mounted on the oil tank; a working beam is provided on the frame, a tail plate and a baffle are mounted on the working beam, a stop is provided between the tail plate and the baffle, a hydraulic cylinder is installed between the tail plate and the stop, the end of the piston rod of the hydraulic cylinder is connected to the back of the splitting blade, a bracket is installed between the stop and the baffle, the bracket is installed on both sides of the working beam, a slider is slidably connected to the working beam, and the bottom of the splitting blade is fixed on the slider with the blade facing the baffle. The wood splitter designed using this invention can solve the problems of not being able to clean the workbench after each splitting action, not being able to increase the speed of the splitting action, and simply increasing the power, which leads to various problems, reduces work efficiency, and even accelerates the wear of moving parts, seriously affecting the service life of the wood splitter itself.

This application relates to a multi-mode hydraulic log splitter, belonging to the field of wood processing machinery technology. The log splitter includes a frame, a base, a lifting cutter head assembly driven by a drive device, and a lifting frame hinged to one side of the frame or base. The lifting cutter head assembly has a first connecting member, and the lifting frame is connected to a flexible traction member. When the flexible traction member is engaged with the first connecting member, the upward movement of the lifting cutter head assembly pulls the lifting frame from the loading position to the closing position, achieving automatic log loading. Furthermore, the bottom of the frame has a reinforcing rib, and the first connecting member and the reinforcing rib have overlapping projections in the vertical direction. When the cutter head descends to its limit position, the first connecting member abuts against the reinforcing rib, maintaining a preset safety gap between the blade and the base. This invention utilizes the reuse of cutter head power to achieve low-cost automatic lifting and provides reliable passive safety limits through structural interference, effectively improving the efficiency and safety of log splitting operations.

This utility model relates to a wood splitter device, and more particularly to a pallet for a wood splitter and a wood splitter; it includes a pallet body (1); the pallet body (1) includes a pallet load-bearing unit (11); both sides of the pallet load-bearing unit (11) are provided with side units (12); a pallet support unit (13) is provided below the pallet load-bearing unit (11); the pallet load-bearing unit (11) is also provided with a first groove (14) for connecting with the wood splitter. The wood splitter designed by this utility model realizes the rapid alignment and installation of the pallet and the wood splitter blade unit, avoiding manual adjustment of position and improving assembly efficiency; similarly, the groove structure forms a mechanical lock to prevent the pallet from shifting laterally during operation.
