[0019] Referring to Figs. 1-3 A kind of brick conveying device, the device is at least by rack 1 and conveying roller 5 composition.In the device conveying roller 5 is installed on rack 1, and pad can be placed on conveying roller 5 by conveying roller 5 drive forward movement.Conveying roller 5 can be driven by conventional chain sprocket.Conveying roller 5 first needs to drive pad to pass through sanding machine and pass through sanding machine to sprinkle a layer of quartz sand on the surface of pad, subsequently pad continues to move under the drive of conveying roller 5, until reach next station and place brick on pad, i.e., when brick is placed on pad, there is actually a thin layer of quartz sand between brick and pad, and after pad is sent into kiln together with brick and is burned into shape, quartz sand forms isolation effect between pad, at this time, the formed brick is basically not bonded with pad due to the isolation effect of quartz sand, i.e., the formed brick can be conveniently taken off from pad, thereby reducing the rate of defective products.

[0020] The sanding machine used in the brick conveying device shares rack 1 with the brick conveying device, and includes sanding assembly 2, uniform assembly 3 and sensing assembly 4.Sanding assembly, uniform assembly 3 and sensing assembly 4 are all installed on rack 1.Uniform assembly 3 is disposed below sanding assembly 2, sanding assembly 2 delivers quartz sand to uniform assembly 3, and uniform assembly 3 is disposed directly above conveying roller 5.When pad is driven by conveying roller 5 to pass below uniform assembly 3, uniform assembly 3 sprinkles quartz sand onto the surface of brick to form a layer of quartz sand on the surface of pad.

[0021] Specifically, sanding assembly 2 includes hopper 21 and discharging part 22, discharging part 22 is disposed in hopper 21 and rotates in hopper 21, the bottom of hopper 21 is provided with sand outlet, and the sand outlet is disposed directly above uniform assembly 3 and communicates with uniform assembly 3.Discharging part 22 includes pipeline 222 that communicates between sand outlet and uniform assembly 3, and valve 221 is disposed at the end of pipeline 222.In use, the end of pipeline 222 is always attached to the surface of uniform assembly 3 to ensure that quartz sand can be accurately delivered to uniform assembly 3.Discharging part 22 includes rotating screw 223, which can be installed at sand outlet or in pipeline 222 above valve 221.One end of rotating screw 223 faces uniform assembly 3, i.e., rotating screw 223 drives quartz sand to fall to uniform assembly 3 by rotating.Rotating screw 223 has the effect of spiral conveying to control the amount and speed of quartz sand delivery, thereby making quartz sand delivery more uniform, reducing the accumulation of quartz sand on uniform assembly 3, and thereby making the distribution of quartz sand on the surface of pad more balanced when uniform assembly 3 is in action.

[0022] Specifically, the uniform assembly 3 comprises a driving roller 31, a driven roller 32 and a belt 33, the driving roller 31 and the driven roller 32 are arranged on the rack 1, the belt 33 is arranged between the driving roller 31 and the driven roller 32, the driving roller 31 and the driven roller 32 can tension the belt 33, and then the belt 33 is driven to rotate by the rotation of the driving roller 31 and the driven roller 32, and the end of the pipeline 222 is directly above the belt 33 and only has a small gap between the belt 33, thereby greatly reducing the phenomenon of random falling of quartz sand, so that the quartz sand can fall on the surface of the belt 33 as much as possible, and the waste of quartz sand is reduced.

[0023] On the basis of the above scheme, a plurality of longitudinal and transverse intersecting grooves 34 can be formed on the belt 33, that is, the surface of the belt 33 forms a grid-shaped pattern, and the quartz sand finally falls into the grooves 34, and the belt 33 is driven to translate by the driving roller 31. When the belt 33 is turned over, the quartz sand falling into the grooves 34 falls on the base plate. Correspondingly, the rack 1 is provided with a flattening assembly 6, the flattening assembly 6 comprises a flattening plate 61 and a linear drive device 62, the linear drive device 62 is fixed on the rack 1, the flattening plate 61 is fixed on the driving shaft of the linear drive device 62, the flattening plate 61 is driven to be attached to the belt 33 by the linear drive device 62, and one end of the flattening plate 61 towards the belt 33 is provided with a brush 63. On the one hand, the brush 63 pushes the piled quartz sand to be flattened, so that the quartz sand can be placed in the grooves 34, and at the same time, the mutual movement of the brush 63 and the belt 33 can brush the excess quartz sand on the belt 33, so as to control the amount of quartz sand. A recovery device needs to be fixed below the conveying roller 5, when the quartz sand falls from the belt 33, the excess quartz sand will fall into the recovery device through the conveying roller 5, thereby reducing the waste of quartz sand.

[0024] The recovery device can be a recovery hopper 7 fixed on the rack 1, the recovery hopper 7 is placed below the conveying roller 5 as a whole, the upper opening of the recovery hopper 7 covers the entire conveying roller 5, and the quartz sand falling through the gap of the conveying roller 5 directly falls into the recovery hopper 7. The inner wall of the recovery hopper 7 is inclined so that the quartz sand is gathered to the lowest point of the recovery hopper 7. The bottom of the recovery hopper 7 is provided with a lower opening, and the lower opening is located at the lowest point of the recovery hopper 7. The quartz sand gathered in the recovery hopper 7 can be recovered and utilized from the lower opening. Specifically, the lower opening can be connected to a recovery pipe, the recovery pipe extends obliquely to one side of the rack 1 and communicates with a recovery box or a recovery bucket placed on one side of the rack 1, thereby recovering the quartz sand and reducing the waste of quartz sand.

[0025] The motors for driving the conveying roller 5, the driving roller 31, the rotating screw 223 and the valve 221 respectively can be automatically controlled.
