[0022] Among them, the mounting frame 104 is fixedly mounted on the main body 101, the slide bar 105 is slidably mounted on the mounting frame 104, the fixed plate 106 is fixedly mounted on the slide bar 105 close to the main body 101, the dredge rod 107 is fixedly mounted on the fixed plate 106 close to the side of the screen 103, the driving assembly is arranged on the mounting frame 104, the size of the dredge rod 107 matches the sieve hole of the screen 103, the number of the dredge rods 107 matches the sieve hole of the screen 103, the dredge rod 107 is made of metal material, the mounting frame 104 has an opening that matches the slide bar 105, and when in use, through the The driving assembly drives the slide bar 105 to move, and the movement of the slide bar 105 drives the movement of the fixed plate 106, and the movement of the fixed plate 106 drives the movement of the dredging rod 107, and the dredging rod 107 moves into the sieve holes of the screen 103, thereby pushing out the waste chips in the sieve holes of the screen 103 to avoid them remaining on the screen 103, solving the problem that the screening part of the existing device cannot be disassembled. With the long-term use of the screening component, small wood waste chips are easily retained in the gaps of the filter, thereby reducing the screening efficiency. Since the screening component cannot be disassembled, the user needs to spend a lot of time when cleaning it, and the labor intensity of the user is increased.

The arc block 111 abuts against the centrifugal wheel 110. The reset component is provided on the fixed plate 106. The rotation of the connecting rod 109 drives the centrifugal wheel 110 to rotate. After the centrifugal wheel 110 rotates and contacts the arc block 111, it drives the arc block 111 to move. The movement of the arc block 111 drives the slide rod 105 to move.

[0025] At the same time, the housing 112 is fixedly mounted on the mounting frame 104, the sleeve rod 113 is slidably mounted on the housing 112, both ends of the spring 114 are respectively connected to the mounting frame 104 and the fixed plate 106, the lower end surface of the sleeve rod 113 is fixedly connected to the fixed plate 106, the pick-and-place element is arranged on the mounting frame 102, the housing 112 has a sleeve groove matching the housing 112, the spring 114 is sleeved on the outside of the housing 112, and the fixed plate 106 moves while driving the sleeve rod 113 to move in the housing 112 while stretching the spring 114. When the arc block 111 is no longer in contact with the centrifugal wheel 110, the spring 114 resets and drives the fixed plate 106 to reset.

[0026] In addition, the mounting frame 102 has a slot 117, the baffle 115 is hinged on the mounting frame 102 and is located at the slot 117, the handle 116 is fixedly mounted on the baffle 115, the mounting frame 102 has a mounting groove matching the screen 103, the mounting groove is connected to the slot 117, the baffle 115 abuts against the screen 103, and the baffle 115 cooperates with the slot 117 to facilitate replacement of the screen 103.

[0027] When the wood processing waste screening device described in this embodiment is used, the driving motor 108 drives the connecting rod 109 to rotate, and the rotation of the connecting rod 109 drives the centrifugal wheel 110 to rotate. After the centrifugal wheel 110 rotates and contacts the arc block 111, it drives the arc block 111 to move. The movement of the arc block 111 drives the sliding rod 105 to move, and the movement of the sliding rod 105 drives the fixed plate 106 to move. The movement of the fixed plate 106 drives the dredging rod 107 to move, and the dredging rod 107 moves into the sieve holes of the screen 103, thereby ejecting the waste chips in the sieve holes of the screen 103 and preventing them from remaining on the screen 103. This solves the problem that the screening part of the existing device cannot be disassembled. As the screening component is used for a long time, fine wood waste chips are easily retained in the gaps of the filter screen, thereby reducing the screening efficiency. Since the screening component cannot be disassembled, the user needs to spend a lot of time to clean it, and the labor intensity of the user is increased.
