Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-3, a feeding device of a building sand sieving machine comprises a feeding box 1, a feeding hopper 2 is installed at the top of the feeding box 1, a discharging pipe 9 is fixed at the bottom of the feeding box 1, the feeding box 1 is connected with the feeding end of a vibrating screen or a drum screen, i.e. sand is conveyed into the feeding box 1 through the feeding hopper 2, and then the sieved sand is conveyed into the sand sieving machine through the discharging pipe 9 at the bottom of the feeding box 1.

Simultaneously at the internally mounted of feeding case 1 there is screen cloth 8, upwards protruding in the middle of the screen cloth 8, and the both sides of feeding case 1 are all stretched out twice of screen cloth 8, and the sand that gets into sieves through screen cloth 8, and the both sides discharge feeding case 1 of screen cloth 8 can be followed in time to large granule material in the screening process to avoid large granule material to pile up the screening effect that influences screen cloth 8.

And be provided with cone 10 at the top of inlet pipe, and the week side of cone 10 is fixed with connecting rod 11, and cone 10 passes through connecting rod 11 to be fixed in the inside of feeder hopper 2, when the feeding in feeder hopper 2, when containing the hard block in the material of input, with cone 10 contact, cone 10 can smash it, avoids the sand of caking to cause discharging pipe 3 to block up.

The top of feeding case 1 is connected with

discharging pipe

3, 3 bottom contacts of discharging pipe have a quantitative section of thick bamboo 5, the right side of a quantitative section of thick bamboo 5 is fixed with closure plate 4, closure plate 4 can carry out the shutoff with the storage pipe, the bottom of a quantitative section of thick bamboo 5 is rotated there is closing cap 6, and closing cap 6 is then slidable mounting in the inside of feeding case 1, it is specific, inside one side at feeding case 1 is fixed with backup pad 12, and closing cap 6 then slides in backup pad 12, one side at a quantitative section of thick bamboo 5 still is fixed with telescopic link 7 simultaneously, telescopic link 7 can adopt electric putter, arbitrary one kind in hydraulic putter or the pneumatic putter, can drive the slip of a quantitative section of thick bamboo 5 in backup pad 12 through the flexible of telescopic link 7.

Through the above-mentioned technical scheme, feeder hopper 2 is used for depositing sand, when getting the material, telescopic link 7 drives quantification section of thick bamboo 5 and moves the bottom of discharging pipe 3, sand in feeder hopper 2 can enter into quantification section of thick bamboo 5 through discharging pipe 3 this moment, when the quantification section of thick bamboo 5 is filled with sand, telescopic link 7 stretches out and draws back once more, drive quantification section of thick bamboo 5 and move to the backup pad 12 outside, in-process closing cap 6 that moves also slides on backup pad 12, closing cap 6 opens under the action of gravity of sand in quantification section of thick bamboo 5 when closing cap 6 separates with backup pad 12 completely, thereby throw in the sand in quantification section of thick bamboo 5, and the volume of quantification section of thick bamboo 5 is certain, consequently, can realize the ration and throw the material, and in-process synchronous drive closure plate 4 that moves in quantification section of thick bamboo 5 removes, when the top of quantification section of thick bamboo 5 separates with discharging pipe 3 gradually, closure plate 4 can contact with the bottom of discharging pipe 3 gradually when quantification section of thick bamboo 5 bottom opening 6 is opened, closure plate 4 can just in proper time can be closed with the reversal extrusion in the quantification section of discharging pipe 5 removal gradually, make the reversal of the closure plate 5 remove and the reversal extrusion that the correspondence of the reversal of the quantification section of the closing cap that the monitoring tube 5 and the reciprocal of the contact of discharging pipe 5 gradually, make the reversal of the contact of the quantification section of the contact of the monitoring tube 5.

Therefore, in the quantitative feeding process, the blockage of the screen 8 caused by more sand can be effectively avoided, the intermittent feeding is also realized, the contact time between the sand and the screen 8 can be increased in the time interval of the twice feeding, the screening effect of the sand can be increased, meanwhile, the programmable controller can be matched with the telescopic rod 7 for use, the telescopic rod 7 can stretch at regular time, the quantitative barrel 5 can be timed and quantitatively fed, and the screening effect of the sand is further improved.

When using, drive a ration section of thick bamboo 5 through the flexible of telescopic link 7 and remove the bottom of discharging pipe 3 or keep away from discharging pipe 3, when removing discharging pipe 3 bottom, in the sand in the feeder hopper 2 can enter into a ration section of thick bamboo 5, and when a ration section of thick bamboo 5 kept away from discharging pipe 3, the sand that will hold is opened automatically to the closing cap 6 of a ration section of thick bamboo 5 bottom and is put in, and the volume of a ration section of thick bamboo 5 removes, consequently can realize the ration and throw the material.

The standard parts used in the application document can be purchased from the market, and can be customized according to the description of the specification and the description of the attached drawings, the specific connection mode of each part adopts conventional means such as mature bolts, rivets, welding and the like in the prior art, and machines, parts and equipment adopt conventional models in the prior art.
