Description

  This invention relates to a solid material sorter.

  It may be necessary to sort and separate solids to be sorted according to size. In such cases, a sieve is often used.

  A conventional sorter is composed of a hopper that stores solid matter to be sorted and a sieve that sorts and separates solid matter (Non-Patent Document 1), and the solid matter is sent from the hopper to the sieve. In order for the sieve to perform the function of the sieve, it is desirable to transport the solid material uniformly to the surface of the sieve, so the width of the hopper is almost the same as the width of the sieve, and the hopper is In order to control the supply amount of the solid substance to the sieve with respect to the speed, the solid substance is conveyed by a vibrator different from the sieve.

  According to such a conventional technique, there is a problem in that each drive source is required for the hopper and the sieve in order to exhibit the performance of the sieve, and the installation space and the manufacturing cost are excessive.

  Therefore, in view of the problems of the prior art, the object of the present invention is to save space and save by placing a hopper above a conveyor having a sieve and allowing the solid matter to be freely dropped from the hopper to the conveyor. An object of the present invention is to provide a sorter capable of realizing the cost.

  In order to achieve this object, the present invention has a structure in which a supply port is provided at the lower end, a hopper that accommodates a solid matter to be selected, a flat plate portion below the supply port, and a reciprocating vibration in the front-rear direction. The conveyor is provided with a sieving portion in front of the flat plate portion, receives the solid matter falling from the supply port by the flat plate portion, and conveys it to the sieving portion.

  The hopper is provided with two supply ports at the front and rear, and the conveyor is provided with two flat plate portions corresponding to the supply ports, and the front flat plate portion is located above the rear portion of the sieve portion, and the rear flat plate portion and A gap in the height direction can be provided between the two.

  Also, the conveyor may be lowered from the back to the front.

  Furthermore, you may form the lower end of a supply port in parallel with a flat plate part.

  The supply port may have a rectangular cross section.

  Furthermore, the sieve part can be provided with a stopper above the front end part.

  The supply port may have a shutter for opening and closing.

  In the configuration of this device, since the hopper that stores the solid matter to be selected is arranged above the conveyor, the solid matter freely falls from the supply port to the upper surface of the flat plate portion of the conveyor and accumulates. The deposited solid matter is reciprocally oscillated in the front-rear direction and conveyed by the conveyor, and the portion in contact with the flat plate portion of the conveyor and the surrounding portion move through the flat plate portion. , And is dispersed throughout the flat plate portion by vibration and conveyed to the sieve portion. An amount of solids corresponding to the solids conveyed to these sieving parts is sequentially supplied from the hopper to the flat plate part of the conveyor.

  On the other hand, since the solid material conveyed to the sieve part is a conveyor that has the same drive source in the sieve part, the solid substance smaller than the gap falls during the conveyance at the sieve part, and from the gap of the sieve part. Large solids move forward past the sieve. In this way, the solid matter to be sorted can be sorted and separated for each size by the sieving part. Therefore, by arranging the hopper above the conveyor and providing the conveyor with a flat plate portion corresponding to the supply port of the hopper, a drive source for supplying solid matter to the sieve portion becomes unnecessary, so space and cost can be saved. Can be achieved.

  The hopper is provided with two supply ports at the front and rear, and the flat plate portion corresponding to the supply port is provided at two locations on the conveyor. The front flat plate portion is located above the rear portion of the screen, By providing a gap in the vertical direction, the sieve part that overlaps with the front flat plate part can be used as a special sieve for the solid matter supplied to the rear flat plate part, and the front side of the overlapping part In the sieving section, a large solid material that has passed through the sieving operation of the rear flat plate portion is added to the solid material supplied from the front flat plate portion. Therefore, since the sieving operation can be performed almost uniformly at the same time in the front-rear direction of the hopper, the processing speed can be improved.

  By lowering the conveyor from the back to the front, it is possible to increase the conveying speed of the conveyor with respect to the solid matter, so that the processing speed can be improved.

  By forming the lower end of the supply port parallel to the flat plate part, the solid matter deposited between the supply port and the flat plate part is continuously conveyed on the conveyor at almost the same height in the width direction and the front-rear direction. And it becomes easy to disperse the solid matter evenly throughout the conveyor. Therefore, the processing speed can be improved.

  If the supply port has a rectangular cross-sectional shape, solids can be transported continuously in a strip with the same width on the conveyor, so it is easy to disperse the solids evenly in the width direction of the conveyor. It becomes. Therefore, the processing speed can be improved. Further, it becomes more effective if the length in the width direction of the supply port is almost the same as the length in the width direction of the conveyor.

  By providing a stopper above the front end of the sieving part, the stopper can drop small solids on the large solids transporting the sieving part to the sieving part side, improving the sorting accuracy. be able to.

  When the supply port has a shutter for opening and closing, the sorting machine can maintain a state where the solid matter is packed in the hopper when the shutter is closed, and the sorting operation can be performed when the shutter is opened.
