the receiving bin with the functions of draining and distributing as shown in fig. 1 comprises a bin body 1, a spiral conveying device 2, a distributing plate moving mechanism, a draining and collecting mechanism, a self-cleaning mechanism and a bracket 3. The upper part of the bin body 1 is square and open; a material distributing plate fixing platform 1-1 is arranged in the middle of the bin body 1; the bottom of the bin body 1 is an arc hopper bottom 1-2, and the side surface of the bin body is provided with a discharge hole 1-3 which is connected with a spiral conveying device 2. The support 3 is arranged outside the bottom of the bin body 1.

The material distributing plate moving mechanism comprises a movable material distributing plate 4, a guy cable 5, a double guide rail 6 and a tensioning driving device 7. In order to avoid the blockage of large garbage entering the bin body 1 without hindrance to subsequent devices, the movable material distributing plate 4 is in a bar grid shape, and the distance between grids is 10 mm. Moisture and small-particle size material accessible movable divides the grid of flitch 4, realizes the waterlogging caused by excessive rainfall function. One end of the inhaul cable 5 is connected with the movable material distributing plate 4, and the other end of the inhaul cable is connected with the tensioning driving device 7. The double guide rails 6 are arranged on the inner wall of the bin body 1, are positioned in the middle and at the upper part of the bin body 1 and are used for guiding the movable material distributing plate 4 to move up and down and fix.

The draining collection mechanism comprises a porous draining plate 8, a draining bin 9, a communicating pipe 10 and a draining tank 11. The porous draining board 8 is provided with holes uniformly, and the aperture is about 5 mm. In order to realize solid-liquid separation and reduce the blockage of holes, the porous draining plate 8 is vertically arranged, one side is a bin body 1, and the other side is a draining bin 9. In order to facilitate subsequent maintenance, the porous draining board 8 is of a pluggable type. If the draining effect is influenced by large-area hole plugging, the porous draining plate 8 can be pulled out for manual cleaning. The communicating pipe 10 is arranged at the bottom of the draining bin 9, horizontally inclines downwards, and the other end of the communicating pipe is connected with a draining tank 11. A backflushing port 12 is arranged below the communicating pipe 10.

The self-cleaning mechanism comprises a self-cleaning connecting rod 13, a self-cleaning brush head 14 and a tension driving device 7. The self-cleaning connecting rod 13 is vertically arranged in the draining bin 9, the bottom end of the self-cleaning connecting rod is provided with a self-cleaning brush head 14, and the top end of the self-cleaning connecting rod is connected with the tensioning driving device 7.

The specific working process is as follows:

the kitchen waste is poured into the opening of the bin body 1 from the waste transport vehicle, then enters the spiral conveying device 2 through the arc hopper bottom 1-2 and the discharge hole 1-3, and is conveyed to the next procedure. At this time, the movable material distributing plate 4 is vertically attached to the inner wall of the bin body 1.

Because the speed of screw conveying material is far less than the discharge speed of the garbage transport vehicle, the lower space of the bin body 1 is gradually filled with the material, and the kitchen waste material is required to be temporarily stopped to be received. At the moment, under the action of the tensioning driving device 7, the movable material distribution plate 4 obliquely moves downwards along the double guide rails 6, and one end of the movable material distribution plate is abutted to the upper material distribution plate fixing platform 1-1. The upper space of the bin body 1 separated by the movable material distributing plate 4 can continue to receive the dumping materials of the garbage transport vehicle, and simultaneously, the requirement of the feeding pause in the lower space of the bin body 1 is met.

Under the action of the spiral conveying device 2, the materials in the lower space of the bin body 1 are gradually conveyed to be finished, and the space is cleared. At the moment, under the action of the tensioning driving device 7, the movable material distribution plate 4 is separated from the material distribution plate fixing platform 1-1, obliquely ascends along the double rails 6 and finally vertically clings to the inner wall of the bin body 1. At this time, the kitchen waste material temporarily stored in the upper space of the bin body 1 falls into the lower space of the bin body 1 under the action of gravity.

The kitchen waste material of keeping in the storehouse body 1 of feed bin no matter be in 1 upper portion space in the storehouse body or lower part space, all receive mutual extrusion effort in the horizontal direction to and the ascending gravity effort of vertical direction. The water and the small-particle size materials contained in the materials vertically flow to the bottom of the bin body 1 under the action of gravity; under the extrusion action, the water flows into the water draining bin 9 horizontally through the water draining holes of the porous water draining plate 8. The leachate accumulated in the leachate tank 9 enters the leachate tank 11 for temporary storage through the communicating pipe 10.

In daily maintenance, a self-cleaning mechanism can be used for mechanical cleaning, or an external water pump can be used for water washing and back flushing. Under the condition of mechanical cleaning, under the action of the tension driving device 7, the self-cleaning connecting rod 13 vertically moves to drive the self-cleaning brush head 14 to physically scrape the holes of the draining holes, so that the holes are cleaned. Under the condition that the pump receives water and washes back flush, under the action of the water pump, high-pressure cleaning water flushes water into the spiral conveying device 2 through the back flush port 12, and the problems of blockage of partial holes and twining blockage of kitchen waste in the spiral conveying process can be solved.
