[0034] The first transmission block 5 is fixedly connected to the push plate 4, and the third transmission block 13 is mounted on the rack 10. The first transmission block 5 passes into the component compartment and engages with the right side of the third transmission block 13, near the end of the wood splitting head 2, to drive the rack 10 to slide away from the wood splitting head 2.

[0042] The bottom of the lifting plate 16 is fixedly connected to the lifting platform 21. A clearance groove is formed at the end of the lifting platform 21 near the processing table 1, and the lifting plate 16 is located within the clearance groove. A rotating shaft 18 is horizontally positioned on the lifting plate 16 along the left-right horizontal direction, passing through the lifting plate 16 and fixedly connected to it. A pusher plate 17 is rotatably mounted on the rotating shaft 18. The pusher plate 17 is parallel to the rotating shaft 18, and its top has an arc-shaped groove along the left-right horizontal direction, within which the wood is located. The pusher plate 17 is located within the clearance groove, and its front end abuts against and limits the movement of the lifting platform 21.

[0043] The processing table 1 is equipped with a transmission mechanism for driving the pusher plate 17 to rotate in both directions, and the transmission mechanism is connected to the pusher plate 17.

[0044] Specifically, the transmission mechanism includes push rod 19 and baffle 20. A push rod 19 is fixedly installed at both the left and right ends of the push plate 17, and the two push rods 19 are arranged in the left-right horizontal direction and are coaxially opposite each other.

[0045] Two horizontal baffles 20 are fixedly installed at the top front end of the processing table 1. The two baffles 20 correspond one-to-one with two push rods 19. Each push rod 19 is in contact with the corresponding baffle 20 for transmission.

[0046] Preferably, the rotating shaft 18 is located between the center of the arc of the push rod 19 and the groove, and the push rod 19 is located between the groove and the processing table 1.

[0047] A rotating shaft 18 is fixedly installed on the lifting platform 21. The rotating shaft 18 passes through the pusher plate 17, and the pusher plate 17 is rotatably connected to the rotating shaft 18. A torsion spring is sleeved on the rotating shaft 18. One end of the torsion spring is fixedly connected to the pusher plate 17, and the other end of the torsion spring is fixedly connected to the rotating shaft 18.

[0048] The front end of the lifting platform 21 is provided with a feeding ramp to facilitate the movement of wood into the groove of the push plate 17.

[0049] Working principle: When using this device to split wood, first activate the hydraulic cylinder 3. The output shaft of the hydraulic cylinder 3 extends and pushes the push plate 4 towards the wood splitting head 2. At this time, the push plate 4 pushes the first transmission block 5 to slide to the right towards the third transmission block 13.

[0050] When the first transmission block 5 contacts the transmission ramp of the third transmission block 13, the first transmission block 5 pushes the third transmission block 13 back to the sleeve 11, and at the same time the third transmission block 13 compresses the second spring 12.

[0051] Next, when the first transmission block 5 slides away from the third transmission block 13, under the elastic force of the second spring 12, the third transmission block 13 slides out of the sleeve 11 but not completely. Then, the wood is placed in the groove of the push plate 17.

[0052] Next, the output shaft of hydraulic cylinder 3 retracts, and the first transmission block 5 slides to the left, approaching the third transmission block 13. When the first transmission block 5 contacts the third transmission block 13, the first transmission block 5 pushes the third transmission block 13 to move to the left. The third transmission block 13 pushes the sleeve 11 to move to the left, and the sleeve 11 drives the rack 10 to move to the left. The rack 10 drives the slider 9 to slide to the left, and the slider 9 compresses the first spring 8.

[0053] When rack 10 moves to the left, it drives gear 14 to rotate. Gear 14 drives lead screw 15 to rotate, and lead screw 15 pushes lifting plate 16 to slide upward. Lifting plate 16 drives lifting platform 21 and pusher plate 17 to move upward, and pusher plate 17 drives the wood to rise.

[0054] When the two push rods 19 on the pusher plate 17 come into contact with the corresponding baffles 20, the two baffles 20 push the corresponding push rods 19 to revolve around the pivot 18. The two push rods 19 drive the pusher plate 17 to rotate backward around the pivot 18 while simultaneously twisting the torsion spring. The pusher plate 17 pushes the wood into the V-shaped groove at the top of the processing table 1.

[0055] Subsequently, as the third transmission block 13 continues to move to the left, the transmission ramp of the third transmission block 13 comes into contact with the second transmission block 6. At this time, the second transmission block 6 pushes the third transmission block 13 back to the sleeve 11, and the third transmission block 13 gradually slides away from the first transmission block 5 and compresses the second spring 12.

[0056] After the third transmission block 13 gradually slides away from the first transmission block 5, under the action of the elastic force of the first spring 8, the slider 9 slides back to the right and drives the rack 10 to move back to the right. At the same time, under the action of the elastic force of the second spring 12, the third transmission block 13 slides out again.

[0057] When rack 10 slides back to the right, it drives gear 14 to reverse. Gear 14 drives lead screw 15 to reverse, and lead screw 15 pushes lifting plate 16 to slide back down. Lifting plate 16 drives pusher plate 17 and lifting platform 21 to move back down. During this process, under the action of torsion spring, pusher plate 17 flips back to its original position and finally abuts against lifting platform 21. At the same time, pusher plate 17 drives two push rods 19 to move down synchronously.

[0058] Finally, the new wood is placed in the groove of the pusher plate 17, and the output shaft of the hydraulic cylinder 3 extends again. At this time, the hydraulic cylinder 3 drives the pusher plate 4 to move closer to the wood splitter head 2 again. The pusher plate 4 moves closer to the wood and pushes the wood towards the wood splitter head 2 after contacting it. The wood is split after contacting the wood splitter head 2.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
