DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0024] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] This embodiment mainly describes the mechanism for facilitating the wood splitter to retract and re-feed, as follows:

[0026] like Figures 1 to 3As shown, a mechanism for retracting and re-feeding a wood splitter comprises a frame 1, one side of the frame 1 is provided with a wood pushing assembly 3 which can reciprocate, the wood pushing assembly 3 is used to push the wood to slide, the other side of the frame 1 is provided with a cutting knife assembly 5 which can split the wood horizontally and vertically, the cutting knife assembly 5 is used to split the wood, a wood placing platform 6 is provided between the cutting knife assembly 5 and the wood pushing assembly 3, a wood supporting platform 4 is provided on the cutting knife assembly 5, the wood supporting platform 4 is used to temporarily store the wood that has not been completely split, the vertical height of the wood supporting platform 4 is higher than the height of the wood placing platform 6, a pushing and pulling member 2 is provided on the wood pushing assembly 3, one end of the pushing and pulling member 2 is located on the wood supporting platform 4 and can move with the movement of the wood pushing assembly 3 When the wood is to be split, the wood is placed on the wood placement platform 6, and the wood pushing component 3 is used to push the wood to move to the cutter component 5. Under the pushing and squeezing of the wood pushing component 3, the cutter component 5 splits the wood horizontally and vertically. While the wood pushing component 3 pushes the wood to move, the push-pull component 2 slides on the wood supporting platform 4 as the wood pushing component 3 moves. The uncut part of the wood after splitting is pushed to the wood supporting platform 4 under the action of the wood pushing component 3. When the wood pushing component 3 moves in the opposite direction, the push-pull component 2 moves with the wood pushing component 3 to return the unsplit wood to the wood placement platform 6 for secondary splitting.

[0027] like Figure 1 and Figure 2 As shown, the wood supporting platform 4 includes a horizontal platform 41 and a limiting side plate 42 fixedly connected to the horizontal platform 41. The cross-sections of the horizontal platform 41 and the limiting side plate 42 are V-shaped. The setting of the V-shaped cross-section can guide and limit the process of the undivided wood being pushed onto the wood supporting platform 4 or retreating from the wood supporting platform 4 to the wood placing platform 6, thereby preventing the undivided wood from being offset during the movement.

[0028] Preferably, the cutting knife assembly 5 includes a horizontal knife 51 and a vertical knife 52. The upper end surface of the horizontal knife 51 is coplanar with the upper end surface of the wood supporting platform 4. The horizontal knife 51 is used to separate the part of the wood that is not cut by the vertical knife 52, so as to facilitate secondary cutting. The vertical knife 52 is arranged below the horizontal knife 51, and one end of the vertical knife 52 is fixedly connected to the bottom of the wood supporting platform 4, and the other end of the vertical knife 52 is fixedly connected to the frame 1. There is at least one vertical knife 52, and the number of vertical knives 52 can be set according to needs. When there are two or more vertical knives 52, there is a spacing between two adjacent vertical knives 52, and the spacing forms a wood discharging channel 53. In the process of continuous cutting of the wood, the wood separated by the vertical knife 52 will push out the wood cut last time, so as to continuously cycle.

[0029] Specifically, the horizontal knife 51 includes a left chopping knife 511 and a right chopping knife 512, and the left chopping knife 511 and the right chopping knife 512 are fixedly connected or integrally formed. The left chopping knife 511 is arranged on the horizontal platform 41, and the right chopping knife 512 is arranged on the limiting side plate 42. In order to make the left chopping knife 511 and the right chopping knife 512 adapt to the horizontal platform 41 and the limiting side plate 42, the cross-sections of the left chopping knife 511 and the right chopping knife 512 are also V-shaped. The V-shaped cross-section of the left chopping knife 511 and the right chopping knife 512 can limit the wood during the wood cutting process to prevent the wood from shifting during cutting, thereby reducing work efficiency.

[0030] Specifically, the wood pushing assembly 3 includes a pushing plate 31 and a telescopic cylinder 32 . The pushing plate 31 is fixedly connected to a telescopic rod of the telescopic cylinder 32 . The telescopic rod is driven to extend and retract by controlling the oil supply of the telescopic cylinder 32 , thereby realizing the reciprocating motion of the pushing plate 31 .

[0031] Specifically, the push-pull member 2 includes a pull plate 21, a pull rod 22 and a connecting rod 23. The connecting rod 23 is fixedly connected to the pushing plate 31 of the wood pushing assembly 3. One end of the pull rod 22 is fixedly connected to the connecting rod 23, and the other end is fixedly connected to the pull plate 21. The pull plate 21, the pull rod 22 and the connecting rod 23 form a three-sided surrounding limiting structure. When the undivided wood is pushed or pulled, the pull rod 22 cooperates with the limiting side plate 42 of the wood supporting platform 4 to guide and limit the two sides of the wood, thereby preventing the undivided wood from shifting during movement.

[0032] Specifically, in order to prevent the wood from shifting during the splitting process, limit platforms 7 for limiting the position of the wood are provided on both sides of the wood placement platform 6. In order to adapt to the use environment of the wood splitter, two sets of wheels are provided at the bottom of the frame 1, and the two sets of wheels are respectively installed on the front and rear sides of the frame 1, each set of wheels has two wheels, and the two wheels are respectively installed on the left and right sides of the frame 1.

[0033] During operation, the wood is placed on the wood placement platform 6, and oil is supplied to the telescopic cylinder 32. The telescopic cylinder 32 drives the telescopic rod to extend, and the telescopic rod drives the propulsion plate 31 to move toward the horizontal knife 51 and the vertical knife 52, and pushes the wood to the horizontal knife 51 and the vertical knife 52. When the wood is pushed and squeezed by the propulsion plate 31, the horizontal knife 51 and the vertical knife 52 split the wood horizontally and vertically. While the propulsion plate 31 pushes the wood to move, the push-pull member 2 slides on the wood support platform 4 with the movement of the propulsion plate 31. The uncut part of the wood after splitting is pushed to the wood support platform 4 under the action of the propulsion plate 31. When it is necessary to pull the unsplit wood on the wood support platform 4 to the wood placement platform 6, the telescopic cylinder 32 is controlled to release oil, and the rod is gradually shortened to drive the propulsion plate 31 to move in the opposite direction, thereby driving the push-pull member 2 to move in the opposite direction to return the unsplit wood to the wood placement platform 6 for secondary splitting, and this is repeated continuously.
