Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention. The structures not specifically mentioned are prior art in this field.
The up-down driving mechanism 14 comprises a driving motor 18, a driving gear 19 is arranged on an output shaft of the driving motor 18, the driving gear 19 is connected with a driven gear 21 through a chain 20, the driven gear 21 is arranged on a transmission shaft 22, two ends of the transmission shaft 22 are connected with mounting seats 23, and the mounting seats 23 are connected with the top of the case 1; two eccentric wheels 24 are arranged on the transmission shaft 22, and the eccentric wheels 24 are movably connected with a cross bar of the U-shaped rod 13.
The upper parts of the side rods 7 are provided with vertical rods 25, the vertical rods 25 are arranged between two inner limiting rods 26, and the inner limiting rods 26 are connected with the inner wall of the case.
And blanking inclined plates 28 are arranged above the sieving port 3 and the non-sieving port 4. The blanking sloping plate 28 facilitates blanking.
A protective plate 27 is arranged above the non-screening opening 4, and the protective plate 27 is connected with the inner wall of the case 1. The inner wall of the housing 1 is protected by a protective plate 27 against the impact of the ore.
The inner wall of the case 1 is provided with a supporting block 16. The support blocks 16 carry the weight of part of the sifter 6.
The utility model discloses a use method and theory of operation: the utility model discloses during the use, ore after the breaker is broken drops into from feeder hopper 2, and the ore falls and cushions on 5 buffer boards, and the impact of whereabouts ore is directly accepted to protection screening piece 6, and the ore glides from 5 buffer boards, gets into and sieves on 6 screening pieces, and the ore that sieves is from the ejection of compact of sieve opening 3, and the ore that does not sieve is from the ejection of compact of 4 sieve openings. Screening piece 6 compares in current screening net, screening principle is that the follow side lever 7 that meets the requirements and screening pole 8, clearance whereabouts between the adjacent screening pole 8, it is unsatisfactory, the ore that needs the repulverize slides down along screening pole 8, because screening pole 8 all is equidistance parallel arrangement, and screen and connect through connecting rod one 9 between pole 8 and its below connecting piece connecting rod two, so the ore does not have horizontal structure when screening pole 8 goes up the gliding and hinders, the ore can be smooth along screening pole 8 gliding, the difficult condition that blocks that takes place.
As described above is the general use and principle of the present invention. If the crushing effect is not good, if meet the heterotypic ore than more, when the condition of card ore takes place on screening piece 6, the utility model discloses actuating mechanism 14 shakes off the ore from top to bottom can also start. The specific process is that the driving motor 18 is started, an output shaft of the driving motor 18 drives the driving gear 19 to rotate, the driving gear 19 drives the driven gear 21 to rotate through the chain 20, the transmission shaft 22 rotates between the two installation seats 23, the two eccentric wheels 24 with the same arrangement position rotate synchronously, and because the eccentric wheels 24 are eccentric, the distances from the wheel edges of the eccentric wheels 24 to the rotation center of the eccentric wheels are different, so that the U-shaped rod 13 continuously contacting with the tops of the eccentric wheels 24 can move up and down. When the U-shaped rod 13 moves up and down, the two vertical rods of the U-shaped rod 13 can ensure the moving direction under the limit of the outer limiting rod 15. The end of the vertical rod of the U-shaped rod can drive the screening part 6 to move up and down through the transmission rod 12, so that ores on the screening rod 8 can be shaken off.
