Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] By Figures 1-10 The present application relates to a melon seed dust removal device, comprising a box 1, a hopper 2 and a partition plate 3 are fixedly arranged in the box 1 to form a feeding cavity 4, a filtering cavity 5 and a dust collecting cavity 6 in clockwise direction, the partition plate 3 is provided with a mounting hole 7, a conical filter cartridge 8 located in the filtering cavity 5 is fixed in the mounting hole 7, and a self-cleaning unit is arranged in the filter cartridge 8; an air inlet pipe 16 and an air outlet pipe 17 are fixed on the box 1, the feeding cavity 4 is communicated with the air inlet pipe 16, the air outlet pipe 17 is communicated with the filtering cavity 5, the air outlet pipe 17 is fixedly communicated with a fan 18, and the fan 18 is fixedly communicated with an exhaust pipe 19.

[0030] In this way, in use, the air inlet pipe 16 is communicated with the inside of the melon seed roasting equipment, and the dust generated in the inside of the melon seed roasting equipment is introduced into the feeding cavity 4 in the box 1 through the air inlet pipe 16 by the power generated by the fan 18, then enters the inside of the filter cartridge 8 through the mounting hole 7, and the dust is filtered through the filter cartridge 8, then the airflow after filtering enters the filtering cavity 5 and is discharged through the air outlet pipe 17, the fan 18 and the exhaust pipe 19 in turn, so that the dust removal operation in the melon seed roasting process is realized.

[0031] Considering that the surface of the filter cartridge 8 will accumulate a lot of dust after a long time of use, it is necessary to clean it regularly by manual way, which is undoubtedly more cumbersome, therefore the following technical solution is provided.

[0032] The self-cleaning unit comprises a center plate 9, a support 10, a ring plate 11, a translation mechanism, an extension mechanism and a power mechanism, the center plate 9 is fixed with the feeding cavity 4 through the extension mechanism, the support 10 is fixed on the center plate 9, the ring plate 11 is rotationally matched with the center plate 9, the translation mechanism is fixed between the feeding cavity 4 and the filter cartridge 8 and is used to drive the center plate 9 to displace, and the power mechanism is fixed on the support 10 and is used to drive the ring plate 11 to rotate; the ring plate 11 is uniformly provided with a rod groove 12, a rod brush 13 is slidingly arranged in the rod groove 12, the rotation positions of the ring plate 11 and the center plate 9 jointly form a ring groove 14, and the center plate 9 is provided with a connecting groove 15, the connecting groove 15 is communicated with the rod groove 12 through the ring groove 14; when not cleaning, the rod brush 13 on the ring plate 11 extends out of the rod groove 12 to close the mounting hole 7; when cleaning, when the center plate 9 displaces towards the filtering cavity 5, the rod brush 13 is gradually retracted into the rod groove 12.

[0033] In this way, when the fan 18 is working, the center plate 9 and the ring plate 11 are located inside the mounting hole 7, at this time, the rod brush 13 extends out of the rod groove 12 and abuts against the inner wall of the filter cartridge 8, at this time, the uniform arrangement of the rod brush 13 can form a filtering barrier to filter the larger foreign matters in the airflow, the larger foreign matters are blocked by the filtering barrier and fall into the dust collecting cavity 6 through the hopper 2, and the smaller foreign matters in the airflow pass through the filtering barrier and enter the inside of the filter cartridge 8, the filter cartridge 8 filters the smaller foreign matters, and finally the filtered airflow passes through the filtering cavity 5 and is discharged out of the box body 1.

[0034] When the dust attached to the inner wall of the filter cartridge 8 is more, the center plate 9 is displaced to the inside of the filter cartridge 8 through the translation mechanism, in the process, the telescopic mechanism is used for guiding to avoid the rotation of the center plate 9, and under the action of the guiding mechanism, the rod brush 13 is gradually retracted into the rod groove 12 to make the rod brush 13 abut against the inner wall of the filter cartridge 8 with a proper length, and the ring plate 11 is driven to rotate through the power mechanism, the ring plate 11 drives the rod brush 13 thereon to clean the dust attached to the inner wall of the filter cartridge 8, so that the self-cleaning process is realized.

[0035] When the center plate 9 is displaced away from the filter cartridge 8 through the translation mechanism, at this time, the rod brush 13 gradually extends out of the rod groove 12, the dust in the filter cartridge 8 is swept into the hopper 2 through the rotating rod brush 13, then falls into the dust collecting cavity 6, and finally the center plate 9 returns to the original position.

[0036] It should be noted that a magnetic ring can be arranged on the inner wall of the mounting hole 7, and the end of the rod brush 13 has a magnetic property that is attracted to the magnetic ring, so that the perpendicularity of the rod brush 13 is maintained by magnetic force to resist the impact of the airflow on the rod brush 13; and a maintenance opening with a cover plate can be arranged at the top end of the box body 1, and a dust discharge opening with a valve can be arranged at the bottom end of the box body 1, so as to facilitate maintenance or discharge of dust from the dust collecting cavity 6.

[0037] Specifically, the telescopic mechanism includes an outer cylinder 20 and an inner rod body 21, the outer cylinder 20 is fixed in the feeding cavity 4, the inner rod body 21 is slidably arranged in the inner rod body 21, the outer cylinder 20 and the inner rod body 21 form a storage cavity 22, the inner rod body 21 is provided with a center hole 23, and the storage cavity 22 is communicated with the connecting groove 15 through the center hole 23.

[0038] In this way, when the center plate 9 is displaced towards the filter cartridge 8, the inner rod body 21 is displaced by the center plate 9, so that the space of the storage cavity 22 is continuously enlarged, thereby forming a negative pressure in the storage cavity 22. Since the storage cavity 22 is communicated with the connecting groove 15 through the center hole 23, and the connecting groove 15 is communicated with the rod groove 12 through the ring groove 14, the rod brush 13 is gradually retracted into the rod groove 12 under the action of the negative pressure. The rod brush 13 is in sliding sealing cooperation with the rod groove 12, and the dust adhered to the rod brush 13 can be cleaned through the slot of the rod groove 12, so that the self-cleaning process of the rod brush 13 is realized.

[0039] Conversely, when the center plate 9 is displaced away from the filter cartridge 8, the space of the storage cavity 22 is continuously reduced, so that the air or liquid in the storage cavity 22 can be transported into the rod groove 12, thereby making the rod brush 13 gradually extend out of the rod groove 12 to work.

[0040] Specifically, the translation mechanism includes a reciprocating motor 24 and a screw rod 25. The reciprocating motor 24 is fixed on the filter cartridge 8, and the screw rod 25 is fixed on the output shaft of the reciprocating motor 24 and is in rotational cooperation with the feeding cavity 4. The support 10 and the center plate 9 are provided with a screw hole 26 in common, and the screw rod 25 is in threaded cooperation with the screw hole 26.

[0041] In this way, the screw rod 25 is rotated by the reciprocating motor 24, the center plate 9 is driven to move by the screw rod 25 through the screw hole 26, and the center plate 9 can advance or retreat along the axis direction of itself under the limiting and guiding action of the telescopic mechanism.

[0042] Specifically, the power mechanism includes a power motor 27, a driving gear 28 and a driven gear ring 29. The power motor 27 is fixed on the support 10, the driving gear 28 is fixed on the output shaft of the power motor 27 and is in meshing cooperation with the driven gear ring 29, and the driven gear ring 29 is fixed on the ring plate 11.

[0043] In this way, the ring plate 11 is rotated by the driving gear 28 through the driven gear ring 29, so that the ring plate 11 is driven to rotate around the center plate 9, thereby driving the rod brush 13 to perform cleaning work.

[0044] Specifically, the ring plate 11 is provided with a ring-shaped limiting groove 30, and the center plate 9 is fixed with a ring-shaped limiting block 31. The limiting block 31 is in rotational cooperation with the limiting groove 30, and the limiting groove 30 is coaxially and communicatively arranged with the ring groove 14. In this way, the relative rotation between the ring plate 11 and the center plate 9 can be realized through the cooperation of the limiting block 31 and the limiting groove 30.

[0045] Specifically, the ring plate 11 is rotatably provided with a protective cover 32, the protective cover 32 is fixed with the inner rod body 21 of the telescopic mechanism, the protective cover 32 is provided with a rod hole 33, and the rod hole 33 is movably and penetratingly matched with the screw rod 25. In this way, the transmission components on the ring plate 11 can be protected by the protective cover 32, and dustproof effect is achieved.

[0046] It should be noted that the elastic bellows can be sleeved on the outer side of the two ends of the screw rod 25 to avoid the influence of dust on the operation of the screw rod 25.

[0047] Specifically, the protective cover 32 is fixed with an upper magnetic plate 34, the discharge port of the hopper 2 is movably provided with a lower magnetic plate 35, the lower magnetic plate 35 is magnetically attracted to the upper magnetic plate 34, the lower magnetic plate 35 is symmetrically and fixedly provided with an inverted T-shaped bottom rod 36, the dust collecting cavity 6 is symmetrically and fixedly provided with a base 37 on the top wall, and the bottom rod 36 is slidably matched with the circular hole on the base 37.

[0048] In this way, when the fan 18 works, the protective cover 32 is located above the discharge port of the hopper 2, the lower magnetic plate 35 is blocked to the discharge port of the hopper 2 under the action of the upper magnetic plate 34, and the dust in the dust collecting cavity 6 is prevented from flowing back to the inside of the hopper 2 due to the influence of the airflow. When cleaning, the lower magnetic plate 35 is no longer blocked to the discharge port of the hopper 2 after the upper magnetic plate 34 and the lower magnetic plate 35 are separated, and the dust generated during cleaning can enter the inside of the dust collecting cavity 6 through the discharge port of the hopper 2 for storage.
