It should be understood that: the kitchen waste sorting device has a partial structure which is the same as that of the food waste sorting device. For example, the conveyor belt, baffles, sorting mechanism and cleaning mechanism are identical in structure and location. But with the difference that: the kitchen garbage sorting device comprises a structure for sorting glass bottles. The first transmission wheel 1 and the second transmission wheel 14 are both driven by a motor.

Be provided with between two second baffles 17 and carry out spacing stop gear to the glass bottle, stop gear includes the limiting plate 19 that a plurality of and second baffle 17 are parallel to each other, and the bottom of limiting plate 19 and the upper surface of second conveyer belt 15 leave mutually, and it is fixed through support 20 between the limiting plate 19 to fix the both ends of support 20 respectively on two second baffles 17.

The bag breaking teeth are preferably triangular pyramids, one edge of each bag breaking tooth is in the same straight line with the bag breaking rod 29, and the included angle between the two surfaces connected by the edge is less than or equal to 30 degrees, so that the plastic bag filled with garbage can be more easily scratched. The plurality of bag-breaking teeth on the same bag-breaking bar 29 are arranged in the same direction. The rotating roller 27 rotates clockwise (with respect to fig. 6). It should be noted that: the bag breaking rods 29 are arranged at the middle position far away from each limit channel, namely, the channel formed between two adjacent circles of bag breaking rods 29 corresponds to the limit channel, so that the bag breaking rods 29 break the bags and simultaneously comb the disordered glass bottles in the garbage to enable the disordered glass bottles to be approximately parallel to the second baffle 17, namely, the glass bottles pass through the channel formed between the two circles of bag breaking rods 29 and enter the limit channel.

Further, in order to pick up the glass bottles in the limiting channel, a sliding rail 22 is arranged above the limiting plate 19, a sliding block 23 is arranged at the bottom of the sliding rail 22, and the length of the sliding block 23 is smaller than that of the sliding rail 22. A plurality of electric push rods are arranged at the bottom of the sliding block 23 along the length direction of the sliding block, mechanical clamping hands 24 are fixed at the output ends of the electric push rods, and the mechanical clamping hands 24 correspond to the limiting channels; a rack 25 with the same length as the slide block 23 is fixed on one side of the slide block, and the slide block 23 is driven to reciprocate on the slide rail 22 through the engagement of a gear on a third motor 26 and the rack 25. It should be understood that: the slide rail 22 and the slide block 23 extend out of the sorting box 31 and are fixed on the sorting box 30 and the partition plate 31, namely, a through hole 33 for taking out glass bottles is formed in the side wall of the sorting box 30, one end of the slide rail 22 extends out of the sorting box 30 through the through hole 33, the top surface of the slide rail 22 is fixed at the top of the through hole 33, and the other end of the slide rail 22 is fixed on the partition plate 31.

The mechanical clamping hand 24 is the prior art, and the structure formed by the mechanical clamping hand 24 and the electric push rod is the same as the manipulator in the doll grabbing machine in the prior art, namely, the mechanical clamping hand 24 is enabled to move downwards through the electric push rod, then the mechanical clamping hand 24 is controlled to be opened to grab the glass bottle, then the electric push rod lifts the mechanical clamping hand 24 together with the glass bottle, and then the third motor 26 is controlled to enable the sliding block 23 to move towards the through hole 33, so that the glass bottle is taken out of the sorting box 30; finally, the glass bottles are put down and collected by controlling the electric push rod and the mechanical clamping hand 24; and resetting the mechanical clamping hand 24, and repeating the steps so as to clamp the glass bottles in the limiting channel.

Furthermore, an observation window can be arranged on the sorting box 30, and a user can manually observe whether a glass bottle exists in the limiting channel and then clamp the glass bottle. Or, set up a camera 34 at the interior top of letter sorting case 30, camera 34 is connected with the controller, whether has the glass bottle in discerning spacing passageway through camera 34 to control mechanical tong 24 and get. The camera 34 identifies the object in the prior art, and details of how to process and identify the image are not described herein. When monitoring whether glass bottles exist in the limiting channels or not, the mechanical clamping hands 24 are driven to clamp the glass bottles as long as the glass bottles exist, and therefore the blockage of garbage caused by the glass bottles existing in each limiting channel is avoided.

In the invention, a liquid collecting hopper 35 is arranged below the upper layers of the first conveying belt 2 and the second conveying belt 15, and a liquid outlet pipe is arranged at the bottom of the liquid collecting hopper 35. The liquid collecting hopper 35 is fixed on the inner wall of the sorting box 30 and the partition plate 31, and the liquid outlet pipe extends out of the sorting box 30.

Furthermore, because the baffle is fixed and the conveying belt is moving, a large friction force exists between the baffle and the conveying belt, and the conveying belt is easily abraded. In order to solve the problem, an annular groove 36 is formed in the position, close to the two side edges of the conveying belt, the baffle extends into the annular groove 36, a plurality of balls 37 are fixed to the bottom surface of the baffle extending into the annular groove 36 through spherical grooves, and when the conveying belt runs, friction between the conveying belt and the baffle is converted into rolling friction from sliding friction, so that abrasion to the conveying belt is reduced. Meanwhile, in order to prevent garbage with smaller particle size from entering the liquid seepage holes, a filter screen 38 is sleeved on the surface of the conveying belt between the two annular grooves 36 on the same conveying belt, so that the liquid seepage holes are prevented from being blocked. It should be noted that: the baffles here are a first baffle 4 and a second baffle 17, the conveyor belts are a first conveyor belt 2 and a second conveyor belt 15, and the weep holes are a first weep hole 3 and a second weep hole 16.

Further, if there is metal product in the rubbish, then only need through the magnet with its absorption go up can, specific position that sets up lay according to actual conditions can.

When the garbage can is used, food waste and kitchen waste are respectively poured into the corresponding devices. Taking food waste as an example, the motor is controlled to drive the first conveyor belt 2 to run, and meanwhile, the first motor 9 and the second motor 13 are controlled to start (rotate in opposite directions), and the rotating speeds of the first motor 9 and the second motor 13 are controlled. Until the garbage runs to the first sorting mechanism through the first conveying belt 2, the plastic bags in the garbage are sorted, and the plastic bags on the first sorting mechanism are taken down through the first cleaning mechanism and collected into the cleaning box 10.

Taking kitchen waste as an example, after the waste is poured onto the second conveyor belt 15, the fourth motor 28 is started to rotate the rotating roller 27, and the camera 34 monitors the condition of the glass bottles in the limiting channel at any time, so that the third motor 26, the electric push rod and the mechanical gripper 24 are controlled to clamp the glass bottles out of the sorting box 30. And the second sorting mechanism and the second cleaning mechanism sort out the plastic bags cut by the bag breaking mechanism. A process cartridge first sorting mechanism and a first cleaning mechanism in which the second sorting mechanism and the second cleaning mechanism operate. The sorted garbage is collected by a collecting box 39 arranged below the conveying belt and then enters the next process.
