It can be known from the general knowledge that when the output power of the equipment is constant, the amount of the raw materials in the shell 2 affects the rotation speed and the sliding speed of the sleeve 26, so that when the amount of the raw materials in the shell 2 is large, the sliding speed of the sleeve 26 is reduced, the sliding speed of the sliding rod 33 is reduced, the sliding speed of the sealing cover 41 is reduced, the time for blanking the cement tank 3, the sand tank 4 and the stone tank 5 at the last time is prolonged, the speed of the raw materials conveyed into the shell 2 is reduced, and when the shell 2 is stirred, the time difference between blanking intervals can be determined according to the amount of the raw materials in the shell 2, so that the stirring efficiency is further improved, and the quality of concrete is further improved.
When the sliding rod 33 slides towards the direction of the fifth supporting plate 16, the rack 42 slides synchronously, because the rack 42 is meshed with the gear 52, the gear 52 rotates clockwise, because the gear 52 is provided with a plurality of groups of clamping grooves used for being matched with a plurality of groups of flexible clamping pieces 57, the circular ring 56 and the rotating rod 51 do not rotate at the moment, the gear 52 idles, when the sliding rod 33 slides towards the direction far away from the fifth supporting plate 16, the gear 52 rotates anticlockwise at the moment, the circular ring 56 drives the rotating rod 51 to rotate, so that the first disk wheel 53 rotates, because the first disk wheel 53 is in transmission connection with the second disk wheel 55 through the belt 54, the second disk wheel 55 rotates, so that the first rotating shaft 71 and the rotating roller 72 rotate, the conveyor belt 7 is conveyed towards the direction of the shell 2, and the effect of conveying raw materials into the shell 2 for stirring is achieved.
When first axis of rotation 71 rotates, second disc 74 drives eccentric rod 75 and rotates in step, because eccentric rod 75 is not on same axis with second disc 74 for under the help of shell fragment 61, filter sieve 6 takes place the shake, filters the stone of whereabouts in the stone jar 5, makes the stone that will accord with the size fall on conveyer belt 7, and because filter sieve 6 is fixed for the slant, makes the stone that is not conform to the size screen out, has reached the effect that has further improved the concrete quality.
When the conveyer belt 7 conveys, the second axis of rotation 73 rotates in step, make cam 8 on it rotate in step, because link 81 offsets with cam 8, make when the elliptical surface contact of link 81 and cam 8, link 81 slides to keeping away from casing 2 direction this moment, thereby the discharge gate of ejection of compact lid 82 and casing 2 does not coincide, make the concrete that the stirring was accomplished in the casing 2 pass through the discharge gate landing of casing 2, and when the circular surface contact of link 81 and cam 8, the elasticity of spring 83 can release, make link 81 reset, thereby ejection of compact lid 82 coincides with the discharge gate of casing 2, but reached automatic discharging need not artificial auxiliary's effect.
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.
