Two connecting pins 63 are arranged between the two support plates 62, and the connection with the excavator or the skid loader is achieved through the connecting pins 63.

[0035] The intermediate connector 1 has two front and rear wall panels 12, which are longitudinally arranged based on the front and rear sides of the connecting end surface 11 and a certain installation space is reserved between the two wall panels 12, and symmetrically distributed pin shaft 1 71 and pin shaft 2 72 are connected between the two wall panels 12, and the split wood gripper 1 2 and the split wood gripper 2 3 are respectively connected to the pin shaft 1 71 and the pin shaft 2 72.

They include a rotating mounting end 8a in the middle for connecting to the intermediate connecting body 1, a power connecting end 8b at the top for connecting to the hydraulic cylinder 4, and a working end 8c at the bottom for grabbing and splitting logs. The working end 8c includes a roller 8d arranged on the contact surface of the log, and a wood splitting knife 8e arranged below the roller 8d. The function of the roller 8d is to reduce the friction between the log and the gripper.

[0037] The hydraulic cylinder 4 is horizontally arranged in the space between the front and rear wall panels 12 of the intermediate connector 1, and one end of its cylinder rod is rotatably connected to the upper end of the wood splitting gripper 2 through a pin shaft 3 73, and one end of its cylinder body is rotatably connected to the upper end of the wood splitting gripper 2 3 through a pin shaft 4 74.

The two ends of the connecting rod 5 are obliquely tied between the wood splitting gripper 2 and the wood splitting gripper 3, one high and one low, and the position is selected at the rotating mounting end 8a of the wood splitting gripper.

[0039] Embodiment 2

[0041] The connecting end face 11 of the intermediate connecting body 1 is connected to the fixed connecting frame 6 via a rotating connecting frame to achieve adjustable installation position. Specifically, the rotating connecting frame includes a hydraulic motor 1 6a and a pinion 6b connected to the output of the hydraulic motor 1, the pinion 6b is meshedly connected to a rotary gear 6c, a rotating frame 6d is fixedly connected above the rotary gear 6c, and the fixed connecting frame 6 described in the first embodiment is installed above the rotating frame 6d.

[0042] Embodiment 3

Specifically, the rotating connecting frame includes a hydraulic motor 6-1, a worm 6-2 driven by the hydraulic motor 6-1, and a turbine 6-3 meshing with the worm.

[0047] An excavator or skid loader is used to supply hydraulic oil to the log splitter. After the hydraulic oil enters the hydraulic cylinder, the cylinder rod retracts and contracts under the power of the oil pressure, thereby driving the two log splitting grippers on the middle connector to open and close the logs. The relative clamping force of the two log splitting grippers splits the logs into small strips of firewood.
