body 431 to feeding cavity 2 in, can realize simultaneously that the material that will fall on inner screen plate 415 through scraper blade 434 promotes to fall to collect in connecing dirt groove 435 (do not sieve the material that falls through inner screen plate 415 promptly), make things convenient for the later stage unified processing.
The working principle of the invention is as follows: when in use, the box cover 311 is opened firstly, the materials are added from the top opening of the feeding box 31, the materials fall on the grid-shaped conveyor belt 32 in the feeding box 31, the grid-shaped conveyor belt 32 moves in a reciprocating way, since the position between the two upper oscillating bars 3231 corresponds to the position of the lower oscillating bar 324 up and down and the arc surfaces of the two upper oscillating bars 3231 are all in contact with the arc surface of the lower oscillating bar 324, therefore, when the grid belt 32 reciprocates (the grid belt 32 does not rotate circumferentially), the two upper oscillating rods 3231 can respectively and alternately abut against the lower oscillating rods 324, thereby the grid-shaped conveyor belt 32 can generate the effect of vertical vibration, the materials on the grid-shaped conveyor belt 32 can be screened, because the bottom of the feeding box 31 is communicated with the feeding cavity 2, the screened materials pass through the latticed conveyor belt 32 and then fall onto the screen plate 33 for screening and then fall onto the buffer filtering and screening device 4; when the outer frame body 431 is not needed to be used, the rotary motor 51 can be started to rotate through the baffle disc 52 to drive the sector-shaped gear ring 53 to rotate, the sector-shaped gear ring 53 is meshed with the driving rack 54, so that the rack 54 can be driven to linearly move (the driving rack 54 and the outer frame body 431 are enabled to simultaneously move towards the direction far away from the feeding cavity 2, when the outer frame body 431 moves to the outside of the feeding cavity 2 through the cavity door 21, the outer frame body 431 can be taken out, then the cavity door 21 is closed), the rotary motor 51 is started to drive the baffle disc 52 and the arc-shaped shielding plate 55 to rotate, so that the arc-shaped opening of the arc-shaped shielding plate 55 faces towards the cavity door 21, namely the arc-shaped top of the arc-shaped shielding plate 55 faces towards the sieve plate 33, on one hand, the arc-shaped shielding plate 55 can play a role in guiding role on materials screened from the sieve plate 33, so that the materials, therefore, the arc-shaped shielding plate 55 can shield the position of the cavity door 21 to a certain extent, so that when the cavity door 21 is opened, dust suction of workers can be reduced or avoided; at this time, the material screened by the screen plate 33 directly falls onto the inner screen plate 415 on the inner screen frame 411 for screening, finally falls to the bottom of the feeding cavity 2, and finally can be output by a discharging device or a discharging port on the dust-free feeding station body 1, and dust generated by sequential screening by the feeding primary screening device 3 and the buffer filtering screening device 4 can be absorbed and filtered by a deviation device on the dust-free feeding station body 1, so that cleaner air is discharged; when the outer frame 431 needs to be used, the rotary motor 51 can be started to rotate through the baffle disc 52 to drive the fan-shaped gear ring 53 to rotate, so that the driving rack 54 and the outer frame 431 move towards the direction of the accommodating groove 34 at the same time, the outer frame 431 is completely sleeved outside the inner screen frame 411 (at the same time, the arc-shaped opening of the arc-shaped baffle plate 55 faces towards the direction of the cavity door 21 and cannot interfere with the material screened by the screen plate 33), after the inner screen frame 411 is completely inserted into the U-shaped opening of the outer frame 431, the dust receiving groove 435 can be inserted into the accommodating groove 34, at the same time, the material screened by the screen plate 33 directly falls onto the outer screen plate 432, at the same time, the reciprocating cylinder 42 can be started, so that the inner screen frame 411 can reciprocate in the U-shaped opening of the outer frame 431 under the action of the reciprocating cylinder 42, namely, the positions of the bottom surfaces of the outer screen plate 432 are abutted through the convex top, therefore, the outer screen plate 432 can vibrate in the U-shaped opening of the outer frame 431, and the material on the outer screen plate 432 falls onto the inner screen plate 415 after being screened to be screened, and finally falls onto the bottom of the feeding cavity 2; when the inner screen plate 415 is used alone to screen materials (that is, when the outer frame body 431 is not used, the outer frame body 431 is located outside the feeding cavity 2), when the feeding cavity 2 is cleaned after the screening operation is finished, the outer frame body 431 can be pushed into the feeding cavity 2, and as the outer frame body 431 gradually enters the feeding cavity 2, the scraper 434 can push a small amount of residual materials which do not pass through the inner screen plate 415 on the inner screen plate 415, and when the inner screen frame 411 enters the outer frame body 431 after being finished, the residual materials pushed by the scraper 434 can fall into the dust receiving groove 435 for collection, so that the later-stage unified treatment is facilitated; the connecting bolts 4161 can be disassembled to facilitate the disassembly, assembly, replacement and cleaning of the inner screen plate 415 from the inner screen frame 411; when the inner screen plate 415 is installed on the inner screen frame 411, because the inner screen plate 415 is located on the annular fixing ring 414 in the opening at the top of the material leakage through groove 412, the top surface of the installed inner screen plate 415 is flush with the top surface of the inner screen frame 411, so that the scraper 434 can scrape off the residual materials on the inner screen plate 415 without interference; a slide bar may be disposed on the opposite inner wall of the U-shaped opening of the outer frame 431, and a sliding groove may be disposed on the corresponding outer wall of the inner screen frame 411, so as to improve the smoothness of the sliding of the inner screen frame 411 in the U-shaped opening of the outer frame 431.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
