Embodiments of the present invention/utility model will be described in detail below with reference to the drawings.
The utility model discloses an embodiment, a building is sieve sand device for mortar, its structure is as shown in attached 1~ 4. The device comprises a sand storage bin 1, a conveying mechanism 2 and a screen 3. The bottom of the sand storage bin 1 is designed for sand flow limiting and auxiliary discharging. One part of the conveying mechanism 2 is positioned below the bottom of the sand storage bin 1, and the other part of the conveying mechanism is inclined and then lifted. The screen 3 is obliquely arranged below the highest point of the inclination of the conveying mechanism 2, and the oblique mesh surface is far away from the sand storage bin 1. The sand to be screened is temporarily stored in the sand storage bin 1, and the sand amount is limited through the outlet end at the bottom of the sand storage bin 1. The sand in the sand storage bin 1 falls on the conveying structure 2, and the conveying speed of the conveying structure 2 is adjustable, so that the amount of the sand falling from the top end of the screen 3 is controllable and adjustable, and the problems that the mortar is increased rapidly at a certain moment and the screening quality is not ideal are solved.
Specifically, the sand silo 1 comprises a silo body 11 and supporting legs 12. The bin body 11 is vertically through and comprises an upper material storage compartment 111, a middle drainage compartment 112 and a lower discharging compartment 113. The upper storage chamber 111 has a hollow rectangular parallelepiped shape. The middle drainage chamber 112 is in a hollow trapezoid table shape with a large upper part and a small lower part, and the upper end of the middle drainage chamber is communicated with the lower end of the upper material storage chamber 111. The supporting legs 12 are vertically arranged outside the upper material storage cabin 111, and the upper end and the lower end of the upper material storage cabin 111 are connected with the outer side of the joint of the upper end of the middle drainage cabin 112. The lower discharge chamber 113 is a hollow cuboid, and has an aspect ratio of 20-10: 1, the upper end of the drainage chamber is communicated with the lower end of the middle drainage chamber 112. An auxiliary discharge mechanism 4 is installed in the lower discharge chamber 113. The auxiliary discharging mechanism 4 includes a support shaft 41 and a kick-off lever 42. The support shaft 41 is installed in the middle of the inner side of the lower discharging compartment 113 along the length direction of the lower discharging compartment 113, and the diameter of the support shaft 41 is 1/5-1/4 smaller than the width of the lower discharging compartment 113. The support shaft 41 is provided with a plurality of rectangular through holes 411 along the axial length direction, and the through holes 411 are directed toward the height direction of the lower discharge chamber 113. The material-poking rod 42, in the shape of a stick of ice cream, correspondingly passes through one through hole 411. The planes on both sides of the material-poking rod 42 are pin-connected with the inner wall of the through hole 411 in the length direction, the upper end thereof extends to the lower end of the middle drainage cabin 112, and the lower end thereof extends to the surface of the conveying structure 2. The length-width ratio of the through hole 411 is 3-5: 1, the length of the through hole 411 is larger than the width of the material poking rod 42, and the width of the through hole 411 is larger than the thickness of the material poking rod 42. During the discharge process, the lower end of the kick-off lever 42 is acted upon by the conveyor 2 and the surface-loaded sand, driving its upper end to move in the opposite direction to the conveying direction. Meanwhile, the upper end of the kick-off rod 42 is driven to shake back and forth under the action of the yarn flowing. Since the kick-off lever 42 is in shaking motion at all times, the effect of unloading can be prevented from being influenced by bridging of sand particles in the lower unloading compartment 113.
And a part of the conveying mechanism 2 is positioned below the lower discharging cabin 113 and is 5 cm-20 cm away from the lower end of the lower discharging cabin 113, and the conveying direction is consistent with the length direction of the lower discharging cabin 113. The conveying structure 2 includes a conveying support 21, a driven support roller 22, a driving support roller 23, a conveyor belt 24, and a variable speed motor 25. The transport carriages 21 are arranged in parallel and constitute a horizontal support section and an inclined upward support section, the horizontal support section of which is located below the lower discharge compartment 113. The outside of the transport carriage 21 is connected to the adjacent leg 12. The driven support rollers 22 are installed in parallel and spaced between the transfer brackets 21, and the driving support roller 23 is installed at the highest point of inclination of the transfer brackets 21 and is installed at one end thereof with a flywheel 26. The flywheel 26 is connected to the variable speed motor 25 by a belt 27. The belt 24 is mounted on the surfaces of the driven supporting roller 22 and the driving supporting roller 23, and its surface toward the lower discharging chamber 113 is in contact with the lower end of the setting lever 42.
In this embodiment, a distribution chute 28 is provided at the highest point of the conveying frame 21 to improve the distribution of the sand particles falling from the belt 24. The bottom surface of the distribution chute 28 is a flat surface, and is inclined toward the screen 3 as a whole, and the highest end is located below the lowest point of the circumferential surface of the driving support roller 23. The sand particles fall from the conveyor 24 onto a distribution chute 28, are dispersed and fall onto the screen 3.
In the present embodiment, in order to improve the pushing action of the conveyor belt 24 to the lower end of the setting lever 42, a semicircular projection 241 is formed on the outer surface of the conveyor belt 24 in the width direction of the lower discharge chamber 113. The height of the protrusion 241 is 1/4-1/3 of the width of the material poking rod 42. When the lower end of the kick-out lever 42 contacts the protrusion 241, it is more easily kicked out. At the same time, the protrusions 241 resist when conveying sand particles, especially when leaning up to support portions, preventing them from sliding on the conveyor belt 24.
And the screen 3 is arranged below the distribution chute 28, and the inclined mesh surface is far away from the sand storage bin 1.
In this embodiment, the sand sieving device for building mortar has the working mode that:
the sand shovel to be screened is placed in the sand storage bin 1 by an excavator, sequentially passes through the upper material storage cabin 111, the middle drainage cabin 112 and the lower discharging cabin 113, finally falls down from the lower discharging cabin 113, and falls down on the conveyor belt 24 relatively uniformly every time, and the falling amount is far smaller than the direct dumping amount of the excavator. Meanwhile, the auxiliary discharging mechanism 4 is used for avoiding sand particle bridging. The sand particles falling onto the conveyor belt 24 fall onto the distribution chute 28 after being lifted to the height, and finally slide off the top end of the screen 3, thereby completing the screening of the sand particles. When the device is used for screening, because the lower discharging cabin 113 of the sand storage bin 1 is used for flow limiting and drainage, the auxiliary discharging structure 4 is used for disturbance and the speed of the transmission belt 24 is adjusted to control the sand screening amount, and the problem that the separation quality is not high due to the fact that an excavator is used for directly shoveling sand on the screen in the prior art is solved.
