[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3This utility model provides an embodiment of a screw press dewatering machine discharge device for kitchen waste treatment, including a collection bin 1. The top of the collection bin 1 has a feeding port for easy collection of kitchen waste. A conveying pipe 12 is connected to the side wall of the collection bin 1, and the end of the conveying pipe 12 is connected to the screw press dewatering machine body 13. The conveying pipe 12 transports the contents of the collection bin 1 to the screw press dewatering machine body 13. The side wall of the screw press dewatering machine body 13 has a discharge port 14. A fixed base 2 is fixedly connected to the bottom of the screw press dewatering machine body 13. After the liquid is discharged through the operation of the screw press dewatering machine body 13, the dewatered kitchen waste is discharged from the inside of the discharge port 14. A collection frame 3 is fixedly connected to the side wall of the fixed base 2. A collection component 4 is set in the bottom of the inner part of the collection frame 3. The collection frame 3 is used to collect the kitchen waste discharged from the discharge port 14. After a certain amount is collected, it is cleaned. A servo motor 5 is fixedly connected to the top of the collection bucket 1. A rotating rod 6 is fixedly connected to the output end of the servo motor 5. The rotating rod 6 is rotatably connected to the inside of the collection bucket 1. The operation of the servo motor 5 drives the rotating rod 6 to rotate, so that the rotating rod 6 rotates inside the collection bucket 1. A lifting block 8 is threadedly connected to the outer surface of the rotating rod 6. A threaded sleeve is set inside the lifting block 8. The inner side wall of the threaded sleeve is set with an internal thread. The top outer surface of the rotating rod 6 is set with an external thread that matches the size of the internal thread. The setting of the internal and external threads allows the rotating rod 6 to drive the threaded sleeve and the lifting block 8 to rise and fall inside the collection bucket 1 during rotation. A push rod 9 is hinged to the side wall of the rotating rod 6. The lifting block 8 drives the push rod 9 to rise and fall inside the collection bucket 1. A fixing block 10 is fixedly connected to the bottom of the rotating rod 6. A limit rod 11 is fixedly connected to the side wall of the fixing block 10. The end of the limit rod 11 is hinged to the side wall of the push rod 9. During the lifting and lowering process, the push rod 9 is pushed by the limit rod 11, so that the push rod 9 opens and closes inside the collection bucket 1, which satisfies the need to fully mix and stir the items stored inside the collection bucket 1. A cleaning mechanism 7 is provided on the outer surface of the rotating rod 6.

[0032] Reference Figures 2-3The cleaning mechanism 7 includes a connecting rod 71, the inside of which is fixedly connected to the outer surface of the rotating rod 6. The rotation of the rotating rod 6 drives the connecting rod 71 to rotate inside the collection bucket 1. The cleaning rod 72 is elastically connected to the inside of the connecting rod 71 through a return spring 73. When the cleaning rod 72 is pushed, it compresses the return spring 73, causing the return spring 73 to deform. Then, it slides inside the connecting rod 71. When resetting, the rebound of the return spring 73 drives the cleaning rod 72 to slide and reset. The cleaning rod 72 is slidably connected inside the connecting rod 71. The end of the push rod 9 contacts the side wall of the cleaning rod 72. The opening of the push rod 9 pushes the cleaning rod 72. After being pushed, the cleaning rod 72 slides inside the connecting rod 71. The side wall of the cleaning rod 72 contacts the inner wall of the collection bucket 1. The cleaning rod 72 rotates with the rotation of the connecting rod 71. The cleaning rod 72 cleans the inner wall of the collection bucket 1 during the rotation process.

[0033] Reference Figures 1-3 The collection component 4 includes a baffle plate 41, which is slidably connected to the inner bottom of the collection frame 3. The inner bottom of the collection frame 3 has a collection port. The baffle plate 41 is used to block the collection port. A push plate 42 is fixedly connected to the bottom of the baffle plate 41. The push plate 42 is slidably connected to the inner bottom of the collection frame 3. By pushing the push plate 42, the baffle plate 41 is driven to slide in the inner bottom of the collection frame 3, which satisfies the function of blocking the collection port and discharging and cleaning the collected items. The baffle plate 41 is elastically connected to the collection frame 3 through a positioning spring 43. During the sliding process, the baffle plate 41 pushes the positioning spring 43, causing the positioning spring 43 to deform. When resetting, the rebound of the positioning spring 43 drives the baffle plate 41 to slide and reset.

[0034] Working principle: During use, the kitchen waste that needs to be dehydrated is put into the inside of the collection bin 1 through the inlet provided on the top of the collection bin 1. Then, the servo motor 5 drives the rotating rod 6 to rotate. The rotation of the rotating rod 6 drives the lifting block 8 to rise and fall. During the rising and falling of the lifting block 8, the push rod 9 is driven to fall. At the same time, the limit rod 11 pushes the push rod 9. After being pushed, the push rod 9 opens. The opened push rod 9 pushes the cleaning rod 72. After being pushed, the cleaning rod 72 squeezes the return spring 73 and slides inside the connecting rod 71. After sliding until it contacts the side wall of the collection bin 1, the rotating cleaning rod 72 cleans the inner side wall of the collection bin 1, which helps to improve the cleanliness of the inner wall of the collection bin 1 during use.

[0035] The kitchen waste inside the collection bin 1 is transported to the inside of the screw press dewatering machine body 13 through the conveying pipe 12. After the liquid is discharged by the operation of the screw press dewatering machine body 13, the dehydrated kitchen waste is discharged from the inside of the discharge port 14. The discharged kitchen waste falls into the inside of the collection frame 3. When a certain amount of kitchen waste is collected in the collection frame 3, the trolley is pushed to squeeze the push plate 42, which drives the baffle plate 41 to squeeze the positioning spring 43 and slide inside the collection frame 3. After the baffle plate 41 slides, the discharge port is exposed, and the kitchen waste inside the collection frame 3 falls into the trolley, thereby completing the dehydration and collection of kitchen waste.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
