In the process that the stone powder enters the second channel 58 through the third air hole 52, part of the stone powder is adhered to the wall surface of the third air hole 52, but because the first air pipe 31 and the blanking hopper 13 designed by the invention are in a rotating state in the working process, the condition that the stone powder is not brought in the process that the airflow flows into the third air hole 52 exists, and at the moment, the airflow can play a role in cleaning the stone powder adhered to the wall surface of the third air hole 52, so that the stone powder is not accumulated at the third air hole 52 in a large quantity, and the third air hole 52 is blocked, namely, the removing equipment designed by the invention, and the third air hole 52 is not easy to be blocked. The concave surface 63 is designed to ensure that stone dust stuck to the wall surface can be smoothly blown in.
As shown in fig. 10, a drive ring 45 is mounted on the outer side of the filter slide 19 via a plurality of circumferentially uniformly distributed attachment plates 46, and the attachment plates 46 are slidably engaged with the treatment shell 17.
As shown in fig. 10, the shaking control mechanism 14 comprises a third motor 47, a third support 48, a rotating disc 49, a first swinging rod 50 and a connecting pin 51, wherein the third motor 47 is fixedly mounted on the outer side of the processing shell 17 through the third support 48, the rotating disc 49 is fixedly mounted on the output shaft of the third motor 47, one end of the first swinging rod 50 is eccentrically and hingedly mounted on the rotating disc 49, and the other end of the first swinging rod 50 is hingedly mounted on the outer circumferential surface of the driving ring 45 through the connecting pin 51. When the third motor 47 works, the third motor 47 drives the rotating disc 49 to rotate, the rotating disc 49 rotates to drive the first swing rod 50 to swing, the first swing rod 50 swings to drive the driving ring 45 to slide up and down in a reciprocating manner under the action of the connecting plate 46 through the connecting pin 51, so that the filtering slide block 19 slides up and down in a reciprocating manner, the effect of vibration is achieved on the filtering slide block 19, the falling of stone powder on the filtering slide block 19 is facilitated, and meanwhile, the flow channel on the filtering slide block 19 is prevented from being blocked.
As shown in fig. 11, the lower end of the third channel 59 of the processing shell 17 is square, and a plurality of swing plates 56 are uniformly hinged on the front side of the lower end of the third channel 59 of the processing shell 17. The function of the wobble plate 56 is to prevent dust.
As shown in fig. 12 (1), the filter slider 19 is composed of an upper part A, B and a lower part A, B, the upper part is provided with a plurality of first flow channels 60 uniformly along the radial direction of the filter slider 19 as shown in fig. 12 (3), and the first flow channels 60 are S-shaped when the filter slider 19 is viewed from above, and the first flow channels 60 are communicated with each other from top to bottom through a plurality of second flow channels 61 as shown in fig. 12 (2); as shown in (1) of fig. 12, the lower portion is a third flow channel 62 uniformly distributed vertically, and the second flow channel 61 communicates with the third flow channel 62. The S-shaped first flow channel 60 and the second flow channel 61 are communicated with the first flow channel 60, so that the stone powder has a longer stroke in the filtering slide block, is convenient to stay in the first flow channel 60, and enters the collecting groove from the second flow channel 61 through the third flow channel 62 under vibration.
In the invention, the stone dust is finally collected in the collecting groove 55 of the processing shell 17 and at the lower end of the first channel 57, the second gate structure 16 is arranged on the inner circular surface of the collecting groove 55, the first gate structure 15 is arranged on the inner circular surface of the lower end of the first channel 57, and the collected stone dust can be cleaned and discharged through the arrangement of the second gate structure 16, because the filtering slide block 19 has the function of blocking the air flow flowing into the lower collecting groove 55, the lower collecting groove 55 can be opened for collection even if the equipment is still in a working state. Because there is airflow inside the first door structure 15, it is necessary to stop the equipment before cleaning the stone dust inside the first door structure 15, and most of the stone dust flows into the lower collecting groove 55, so that less stone dust is collected at the lower end of the first passage 57, and the stone dust can be cleaned once a day or several days in a shutdown state.
The specific working process is as follows: when the cleaning device designed by the invention is used, the machine-made sand is placed in the feeding hopper 8, a power source is output through the first motor 6, the rotation shaft of the driving thread piece is transmitted through the first gear 7 to rotate, the rotation shaft of the spiral piece 4 drives the spiral piece 4 to rotate, and the spiral piece 4 rotates to convey the machine-made sand in the feeding hopper 8 into the discharging hopper 13 on the upper side along the feeding conveying pipe; after the machine-made sand is conveyed into the discharging hopper 13, controlling the second motor 12 to work, driving the second gear 21 to rotate by the second motor 12, driving the third gear 22 to rotate by the second gear 21, driving the transmission sleeve 24 to rotate by the third gear 22, driving the discharging hopper 13 to rotate by the transmission sleeve 24, and enabling the machine-made sand inside the discharging hopper 13 to fall in a spiral shape at the opened discharging hole 34 by the rotation of the discharging hopper 13; on the other hand, the rotation of the lower hopper 13 can drive the sun wheel 27 to rotate through the mounting sleeve 32 on the lower hopper, the rotation of the sun wheel 27 drives the three planet wheels 28 to rotate, the rotation of the three planet wheels 28 drives the transmission ring shell 29 to rotate through the tooth matching, and the rotation of the transmission ring shell 29 drives the first air pipe 31 mounted on the lower side of the transmission ring shell 29 to rotate; when the second air pump 39 and the first air pump 11 are controlled to work simultaneously during operation, the second air pump 39 works to blow air into the first air pipe 31 through the connecting ring 36 of the second air pipe 37, the air in the first air pipe 31 blows out along with the rotation of the first air pipe 31 to blow the thin machined sand falling through the blanking hole 34, most of stone powder in the falling machined sand can enter the second channel 58 from the third air hole 52 formed in the third channel 59 of the processing shell 17 after being blown by the air in the first air pipe 31, after the stone powder is blown into the second channel 58, the stone powder falls onto the filtering slide block 19 along with the air blown out from the first air pipe 31 in the second channel 58 together with the stone powder and the suction force transmitted into the second channel 58 by the first air pump 11 through the first channel 57, and passes through the first channel 60, the second channel 61 and the third channel 62 formed in the filtering slide block 19, the majority falls into the collection trough 55 on the underside of the second channel 58 and the minority passes through the area of communication between the second channel 58 and the first channel 57 into the first channel 57.
During use, the second gate structure 16 may be opened to remove the stone dust in the collection tank 55, and the first gate structure 15 may be opened to remove the stone dust at the lower end of the first passage 57 once after the completion of use or after a day or several days of use.
The machine-made sand after the stone powder is removed falls onto the transportation mechanism 10 in the third channel 59, and is transported to the finished product collection box 9 by the transportation mechanism 10 to be collected.
