When the workman need filter flour, the workman at first need pour flour into in unloading mechanism 4 earlier, the flour in the unloading mechanism 4 can slide in manual screening mechanism 3, the workman can make manual screening mechanism 3 forward and backward motion at an interval afterwards, and then manual screening mechanism 3 can filter flour, when the workman need not filter flour temporarily, the workman can make manual screening mechanism 3 stop motion, thereby screening mechanism can stop to filter flour temporarily, if the workman still need continue to filter flour, the workman repeats above-mentioned operation once more, this equipment can appear filtering flour.
When flour is located in the sieve 32, a worker can move the sieve 32 to the front side and the rear side at intervals in the support plate 31, the first spring 33 can be deformed and reset adaptively according to actual conditions, the sieve 32 can sieve the flour with smaller particles into the material collection frame 34 for collection, the flour with larger particles can be left in the sieve 32, when the worker does not need to sieve the flour for the moment, the worker can stop moving the sieve 32, so that the sieve 32 can stop sieving the flour into the material collection frame 34 for the moment, and if the worker needs to continue to sieve the flour, the worker repeats the operation again, and the device can quickly sieve the flour.
The worker firstly needs to pour flour onto the feeding plate 44, the flour on the feeding plate 44 slides into the lower charging barrel 42, the flour in the lower charging barrel 42 slides onto the screen 32, when the amount of the flour in the lower charging barrel 42 is not large, the worker can pour the flour onto the feeding plate 44 again, the worker repeats the operation again, and the device achieves spaced feeding of the flour.
It takes a lot of effort for a worker to manually slide the screen 32 to the front side and the rear side at intervals, the worker may rotate the motor 51, the rotation of the output shaft of the motor 51 may rotate the third rotating shaft 54, the rotation of the third rotating shaft 54 may rotate the first gear 55, the rotation of the first gear 55 may rotate the second gear 56, the rotation of the second gear 56 may rotate the first rotating shaft 52, and the first belt 57 and the second rotating shaft 53 may rotate accordingly, so that the diamond 58 rotates to contact the screen 32, the diamond 58 may slide the screen 32 to the rear side, the first spring 33 is compressed, the diamond 58 rotates to temporarily stop contacting the screen 32, the first spring 33 is reset to slide the screen 32 to the front side, when the worker temporarily does not need to slide the screen 32, the worker may turn off the motor 51, and if the worker further needs to slide the screen 32, the worker repeats the above operations again, the equipment can make the sieve 32 slide to the front side and the back side at intervals, and effectively reduces the labor intensity of workers.
In order to avoid waste caused by continuous sliding of flour in the lower material cylinder 42 onto the sieve 32, when the sieve 32 slides to the rear side to contact with the fourth rotating shaft 68, the sieve 32 will make the fourth rotating shaft 68 rotate, and then the fixture 69 will rotate along with it, the third spring 610 is stretched, the fixture 69 will not temporarily clamp the U-shaped pull rod 65, then the worker can pull the U-shaped pull rod 65 to the rear side, the sliding of the U-shaped pull rod 65 to the rear side will drive the blocking pull plate 64 to move to the rear side, the second spring 66 will be stretched, the blocking pull plate 64 will temporarily stop blocking the lower material cylinder 42, at this time, flour in the lower material cylinder 42 will slide onto the sieve 32, when the sieve 32 slides to the front side to temporarily stop contacting with the fourth rotating shaft 68, the third spring 610 will make the fixture 69 rotate, the fixture 69 will drive the fourth rotating shaft 68 to rotate, the second spring 66 will reset to make the U-shaped pull rod 65 slide to the front side, the U-shaped pull rod 65 slides to the front side to drive the material blocking pull plate 64 to move to the front side, the material blocking pull plate 64 can block the lower charging barrel 42 again, flour in the lower charging barrel 42 can stop sliding to the screen 32 temporarily at the moment, the U-shaped pull rod 65 can be clamped again by the clamping block 69, so that the flour sliding amount can be controlled at intervals by the device, and the labor intensity of workers is effectively relieved.
In order to avoid the flour blocking the discharging barrel 42, when the second rotating shaft 53 rotates, the second rotating shaft 53 rotates to drive the bevel gear set 74 to rotate, the bevel gear set 74 rotates to drive the fifth rotating shaft 72 to rotate, the fifth rotating shaft 72 rotates to drive the second belt 75 to rotate, the second belt 75 rotates to drive the screw rod 73 to rotate, the flour in the discharging barrel 42 is extruded by the rotation of the screw rod 73, when the fifth rotating shaft 72 stops rotating, the screw rod 73 temporarily stops extruding the flour in the discharging barrel 42, and if the worker needs to continuously extrude the flour in the discharging barrel 42, the worker repeats the operations again.
Because the flour has certain fluidity, part of the flour can be adsorbed on the inner wall of the lower charging barrel 42, when the screw rod 73 rotates, the rotation of the screw 73 drives the space cam 81 to rotate, the rotation of the space cam 81 drives the sliding block 83 to slide downwards on the guide rod 82, the sixth spring 84 is compressed, the sliding block 83 drives the fourth side link 85 to slide downwards, the ring 86 slides downwards along with the ring, the flour on the inner wall of the charging barrel 42 is scraped off by the ring 86, the space cam 81 rotates continuously, the space cam 81 rotates to drive the sliding block 83 to slide upwards on the guide rod 82, the sixth spring 84 resets to assist the sliding block 83 to slide upwards, the fourth frame connecting rod 85 will slide upwards, and the ring 86 will slide upwards, the ring 86 will scrape the flour on the inner wall of the lower material cylinder 42 again, reciprocating this equipment like this can scrape the flour of feed cylinder 42 inner wall down to the effectual flour of avoiding can adsorb at feed cylinder 42 inner wall down.
No matter how the flour slides on the sieve 32, unevenness is inevitable, so when the first rotating shaft 52 rotates, the first rotating shaft 52 can enable the gear lacking 91 to rotate, when the gear lacking 91 rotates to be in contact with the rack pushing plate 92, the gear lacking 91 can enable the rack pushing plate 92 to slide towards the rear side, the seventh spring 93 is stretched, the rack pushing plate 92 slides towards the rear side to scrape the flour on the sieve 32, when the gear lacking 91 rotates to be temporarily stopped to be in contact with the rack pushing plate 92, the seventh spring 93 resets to enable the rack pushing plate 92 to slide towards the front side, and therefore the device can continuously keep the flatness of the flour on the sieve 32.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
