Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.
From fig. 1 to fig. 3, the utility model discloses a screen cloth 1 of low slope about one, screen cloth 1's bottom is equipped with a first arc 2 that the arc top is down, coaxial fixed has a pivot 3 in the first arc 2, the coaxial fixed gear 4 that has of rear side of pivot 3, gear 4's below is equipped with a rack 5 that can slide about, rack 5's left end articulates there is a connecting rod 6, connecting rod 6's left end is equipped with a carousel 7 through motor drive, connecting rod 6's other end eccentric articulates on carousel 7, equipartition and a plurality of through-hole 8 on the first arc 2, the left and right sides of first arc 2 respectively is equipped with a second arc 9 with first arc 2 coaxial arrangement, the concave surface of two arcs is relative, first arc 2 can slide with two second arcs 9 adherence, the left and right sides terminal surface of first arc 2 is higher than the lower terminal surface that corresponds side second arc 9 all the time.
In order to fix the screen mesh 1, a support 10 is arranged below the screen mesh 1, and the screen mesh 1 is fixed on the support 10.
In order to fix the two second curved plates 9, a vertical plate 11 fixed on the ground is arranged on the outer side of each second curved plate 9, and the second curved plates 9 are fixed on the corresponding vertical plate 11.
In order to realize the reciprocating rotation of the first arc-shaped plate 2, a plurality of supporting rods 12 are arranged on the rotating shaft 3, one end of each supporting rod 12 is fixed with the rotating shaft 3, and the other end of each supporting rod 12 is fixed on the first arc-shaped plate 2.
In order to realize that the rack 5 can slide left and right, a support frame 13 is arranged below the rack 5, a sliding block 14 is arranged on the support frame 13, a sliding groove 15 matched with the sliding block 14 is arranged on the lower end face of the rack 5, and the sliding block 14 is arranged in the sliding groove 15 and can slide in the sliding groove 15.
The utility model discloses a concrete working process is: this device opens the drive switch of motor when using, the motor rotates and drives carousel 7 and rotate, carousel 7 rotates and drives its eccentric articulated connecting rod 6 and remove, because the connecting rod 6 other end articulates there is rack 5 that can slide from side to side on support frame 13, rack 5, connecting rod 6 and carousel 7 constitute a crank rocker structure, consequently reciprocating motion about rack 5 under the drive of motor, the reciprocating motion meshing of rack 5 drives gear 4 reciprocating rotation, thereby realize through the fixed pivot 3 of bearing frame through connecting rod 6 drive first arc 2 reciprocating rotation, this rotation in-process, two terminal surfaces about first arc 2 will be higher than the lower terminal surface of its corresponding side second arc 9 all the time, consequently, the gap can not appear between first arc 2 and the second arc 9.
After the readiness, the workman is even with the sand toward laying on the screen cloth 1, most sand this moment can directly be sifted through screen cloth 1, and less part sand and stone drop to first arc 2 in through screen cloth 1 bottom in addition, the reciprocal rotation of first arc 2 for remaining less part sand sieves out through-hole 8, and remaining stone reserves in first arc 2, and it can to dial out the front side that the stone leads to first arc 2 through the scraper blade after a period.
The significant benefits of the present device: this device sets up the first arc roof of reciprocal rotation below traditional screen cloth 1, and the reciprocal rotation through first arc 2 will arrange in the mixture of the stone in first arc 2 and sand and carry out screening once more, and the sand directly falls into to first arc 2 below through-hole 8, and the stone can be scraped out from the front side of first arc 2 through the scraper blade, convenient collection, the problem of adhesion sand when effectual solution was retrieved the stone.
The utility model discloses think about novelty, the structure is ingenious, and the practicality is strong, and the effectual current sand screening device of having solved sends the problem of screening sand inefficiency, need carry out the secondary screening sand usually.
