[0033] In the prior art, general wood processing equipment does not use large-scale bag dust removal equipment. It is usually installed on the machine tool as a dust removal mechanism to perform dust removal work and filter through the filter 2. The existing maintenance mechanism can only observe the blockage condition of the filter 2, and the filter 2 still needs to be cleaned manually, or the filter 2 is cleaned by backblowing pulse airflow, but it requires shutdown, which is time-consuming and labor-intensive, and it is impossible to automatically clean the filter 2 while observing the blockage condition.

[0034] The utility model provides a maintenance mechanism for a wood processing dust removal device, such as Figure 1 and Figure 2 As shown, in the present embodiment, the inspection mechanism is arranged in the dust removal channel 1, and the dust removal channel 1 can be a dust removal box, a dust removal pipe and other structures. Two spaced filter screens 2 and a scraper assembly 3 detachably installed in the dust removal channel 1 are rotatably installed in the dust removal channel 1, and the scraper assembly 3 is in contact with the windward surface of the filter screen 2; the inspection door 11 on the dust removal channel 1, the inspection door 11 is arranged at the upper end of the filter screen 2 and allows the filter screen 2 to enter and exit the dust removal channel 1, the inspection door 11 is mainly used for the installation and replacement of the filter screen 2 and the scraper assembly 3, in order to ensure air tightness, the inspection door 11 is sealed and connected to the dust removal channel 1; the inspection mechanism is located between the two filter screens 2, and the two filter screens 2 are set to filter screens 2 with different filter apertures, which filter different particles of dust in turn. In the present embodiment, one mainly filters large particles of wood chips, and the other filters fine dust.

[0035] For the inspection and maintenance of the above-mentioned dust removal channel 1, an inspection mechanism is set up, which includes a rotating block 21, a transmission rod 4, a transmission gear 5, a transmission gear rod 51, an electric push rod and a camera assembly 6; the rotating block 21 is fixed at the center of the two filter screens 2, and the two ends of the transmission rod 4 are respectively connected to the rotating blocks 21 on the two filter screens 2, the transmission gear 5 is fixed on the transmission rod 4, and the transmission gear rod 51 is meshed with the transmission gear 5 for transmission. The electric push rod is fixed in the dust removal channel 1 and connected to the transmission gear rod 51 to control the movement of the transmission gear rod 51. In order to ensure the stability of the movement of the transmission gear rod 51, a sliding track is set in the dust removal channel 1 to move the transmission gear rod 51. One end is embedded in the sliding track so that it can move along the sliding track, limit its movement, and improve the stability of its movement; the maintenance work is mainly to observe the condition of the filter 2 and automatically clean and dust the maintenance filter 2. The specific actions are: after receiving the maintenance command, the electric push rod starts to push the transmission gear rod 51 to move back and forth, ensuring that the transmission gear 5 rotates at least one circle, so that the windward surface of the filter 2 (the filtered impurities are mainly accumulated on the windward surface of the filter 2) is in contact with the scraper assembly 3, and the dust impurities accumulated on the filter 2 are scraped off. Since the transmission rod 4 can drive the two filter screens 2 to rotate at the same time, and scraper structures are provided on the two filter screens 2, it is ensured that the two filter screens 2 are rotated and cleaned.

It is set to a mesh structure to prevent excessive wood chips from entering and reduce the frequency of clogging of the filter screen 2. The other end is provided with a connecting pipe 13, and the connecting pipe 13 is detachably connected to the suction fan, which is convenient for installation and disassembly between the dust removal channel 1 and the suction fan, and easy to disassemble and maintain independently.

[0041] Regarding the installation of the filter 2, a mounting block 14 is provided in the dust removal channel 1, and the filter 2 is clamped on the mounting block 14.
