The conveyor table 1 is arranged on the ground surface and is used to receive the wood chips conveyed by the previous process. There is a height difference between the conveyor table 1 and the previous process, and the wood chips conveyed by the previous process are stacked on the conveyor table 1 in sequence under the action of gravity to form a wood chip pile. The truss 2 is of I-beam steel structure and includes columns 21 and cross beams 22. The columns 21 and the cross beams 22 are combined to form a frame. The truss 2 starts from the conveyor table 1 and extends towards the wood chip placement area. The moving platform 3 is a rectangular steel frame structure and is horizontally movably connected to the cross beam 22 of the truss 2. The lifting platform 4 is smaller in size than the moving platform 3 but is also a rectangular steel frame structure. The lifting platform 4 is movably connected to the moving platform 3 along the direction of gravity. The lifting platform 4 is horizontally moved to a suitable position through the moving platform 3, and then the lifting or placement of the wood chip pile is realized through the vertical movement of the lifting platform 4. The lifting fork 5 includes a fork rod 51 and a number of fork blades 52.

By moving the fork rod 51, a number of fork blades 52 are driven to insert into or leave the bottom of the wood chip pile. When the fork rod 51 inserts into the bottom of the wood chip pile, it can form a restriction on the gravity direction of the wood chip pile, so as to lift the wood chip pile. Conversely, the wood chip pile is placed. The moving platform 3 is provided with a translation drive assembly 31 for driving the sliding of the moving platform 3. The moving platform 3 is provided with a lifting drive assembly 41 for driving the movement of the lifting platform 4.

The lifting assembly 7 includes a plurality of top rods 71. The top rod 71 is inserted between the conveyor belt 62 and the support roller 63. The top rod 71 can move from bottom to top and pass through the extended surface of the conveyor belt 62 to contact the bottom of the wood chip pile, and continue to move to lift the wood chip pile, so that a gap is formed between the wood chip pile and the conveyor belt 62. The fork 52 can move and extend between the corresponding adjacent top rods 71 ​​to the bottom of the wood chip pile. The conveying platform 1 realizes the continuous transmission of wood chips through the cooperation of the power roller 61 and the conveyor belt 62. The top rod 71 of the lifting component 7 is lifted when necessary, so that the fork 52 can extend between the top rods 71 ​​to clamp the wood chips.

The shell of the lifting driving member 73 is connected to the base 11, and the output end is connected to the sliding seat. The plurality of push rods 71 ​​are driven to move together at the same time through the sliding frame 72.

[0033] Furthermore, the conveying assembly 6 further includes a crossbar 65 and a plurality of leveling vertical pieces 651. The crossbar 65 is disposed at the end of the machine base 11 and is in the same plane as the support roller 63. The leveling vertical pieces 651 are disposed at intervals on the crossbar 65 and extend vertically upward. The leveling vertical pieces 651 are disposed at intervals on the crossbar 65 and extend vertically upward to level the conveyed wood chips. The neatness of the stacking of the wood chips is improved, the gaps and unstable factors during stacking are reduced, and the stability of the stacking structure is enhanced.

[0034] As the wood chips fall into and are lifted (when lifted by the top rod 71), debris or wood chips fall onto the conveyor platform 1. If they are not cleaned in time, they may easily fall into the internal structure of the conveyor platform 1 and cause internal parts to get stuck. In addition, the randomly falling debris or wood chips affect the working environment.

[0035] Therefore, in order to process the debris or wood chips. The wood chip transfer and stacking device also includes a crushing assembly 8 and a chip collection assembly 9.
