[0023] As a further implementation scheme of the above technical scheme: a dual-axis motor 8 is fixed to the right side of the device housing 1 by bolts, and two driving wheels 9 are fixed to the power output shaft of the dual-axis motor 8. A rotating structure is formed between the driving wheels 9 and the dual-axis motor 8. Connecting rods 10 are fixed to the outer walls of the two driving wheels 9. The dual-axis motor 8 synchronously drives the two driving wheels 9 to rotate, thereby driving the compacting mechanism to operate and compact the filtered wood chips.

[0024] As a further implementation scheme of the above technical scheme: the outer surface of the connecting rod 10 is rotatably connected to the hinged rod 11 through a bearing, and the end of the hinged rod 11 is hingedly connected to the movable rod 12. Through the cooperation of the connecting rod 10 and the hinged rod 11, the movable rod 12 can be driven to move linearly to achieve a pushing effect.

[0025] As a further implementation scheme of the above technical scheme: the outer surface of the movable rod 12 is sleeved with a linear bearing 13, the outer wall of the linear bearing 13 is sleeved with a fixed sleeve 14, the fixed sleeve 14 is fixedly connected to the device housing 1, the movable rod 12 passes through the inner wall of the device housing 1, and a clamping plate 22 is fixed to the end of the movable rod 12. The clamping plate 22 moves in the device housing 1 to push the fallen wood chips to the left side. The linear bearing 13 arranged in the fixed sleeve 14 can ensure the smooth operation of the movable rod 12.

[0026] During specific implementation, before using the wood chip recovery device for producing wooden veneer panels, the device housing 1 is first placed in a suitable position, and the collected wood chips are poured into the feed stop 2. The filter screen 3 can block the gravel in the wood chips, so that the filtered wood chips pass through the guide plate 7 and fall into the device housing 1. At the same time, the dual-axis motor 8 is started, and the two driving wheels 9 are synchronously driven to rotate. With the cooperation of the connecting rod 10 and the hinged rod 11, the movable rod 12 is driven to move in a straight line, thereby driving the clamping plate 22 to move in the device housing 1, pushing the fallen wood chips to the left, and the linear bearing 13 arranged in the fixed sleeve 14 can ensure the smooth operation of the movable rod 12.

[0027] As a further implementation scheme of the above technical scheme: a fixing frame 15 is fixed on the inner side of the movable rod 12, and a first moving block 16 is fixed on the end of the fixing frame 15. When the movable rod 12 moves, it will drive the fixing frame 15 to move, so that the first moving block 16 is inserted into the device housing 1.

[0028] As a further implementation scheme of the above technical scheme: the inside of the device housing 1 is slidably connected with a second moving block 17 matching the first moving block 16, and a push rod 18 is fixed to the upper end of the second moving block 17. The push rod 18 penetrates the upper surface of the device housing 1, and a push plate 19 is fixed to the end of the push rod 18. The contact surface between the first moving block 16 and the second moving block 17 is an inclined surface. The second moving block 17 is driven by the thrust of the first moving block 16 to move vertically, so that the push rod 18 drives the push plate 19 to move, thereby pushing the filter 3.

[0029] As a further implementation scheme of the above technical scheme: a fixing rod 20 is passed through the interior of the fixing block 6, the fixing rod 20 is hingedly connected to the mounting member 4, and a spring 21 is sleeved on the outer surface of the fixing rod 20. During the process of the spring 21 restoring and extending, the fixing rod 20 is pushed to reset, so that the mounting member 4 collides with the rubber pad 5 on the fixing block 6, thereby causing the filter screen 3 to vibrate to a certain extent, so as to better filter the wood chips on the filter screen 3.

[0030] During specific implementation, when the movable rod 12 moves, it will drive the fixed frame 15 to move, so that the first movable block 16 is inserted into the device housing 1 and contacts the second movable block 17. Since the contact surface of the first movable block 16 and the second movable block 17 is an inclined surface, the second movable block 17 is driven by the thrust of the first movable block 16 to move vertically, so that the push rod 18 drives the push plate 19 to contact the upper fixed rod 20. At this time, the fixed rod 20 is subjected to the thrust, which drives the spring 21 to be compressed and pushes up a mounting member 4. When the movable rod 12 moves in the opposite direction, the second movable block 17 loses the thrust and drives the push plate 19 to reset under the action of its own gravity. At this time, the spring 21 resets and extends, pushing the fixed rod 20 to reset, causing the mounting member 4 to collide with the rubber pad 5 on the fixed block 6, thereby causing the filter screen 3 to vibrate to a certain extent, which can better filter the wood chips on the filter screen 3 and improve practicality.
