[0033] The working process of the integrated kitchen waste tracking device and control system of the present invention is described in conjunction with the accompanying drawings.

[0034] The upper end of the crushing device 7 is connected with a feed port, and the food waste to be processed is placed in the feed port, and the blade 26 crushes the food waste through the rotation of the driving shaft 38; the original power of the driving shaft 38 is transmitted to the driving shaft 38 through the rotation of the motor 4, the speed reduction and torque increase of the reducer 5; the food waste crushed by the blade 26 is connected to the feed port of the dehydrator 9 through the connecting sleeve; the driving shaft 38 transmits power to the dehydrator 9 through the belt transmission mechanism 8; the food waste enters from the screw 49 on the left side of the dehydrator 9, and is transmitted through the screw 49. In the middle of the screw 49, the water is separated by compression and flows into the large drainage bucket 60 or the small drainage bucket 62 from the gap of the filter cartridge 51. The dehydrated food waste is squeezed out from the extrusion plate 57 at the right end of the dehydrator 9 and is transmitted to the material trough 22 of the briquetting device 9 through the conveyor belt.

[0035] For different users, the serial number on the bottom surface of the briquetting head 21 of the briquetting device 9 is different and uniquely points to a certain user. Therefore, after the food waste in the material trough 22 is briquetized by the pressing rod 19, a food waste block with the serial number is formed. Therefore, by reading the serial number pressed on the food waste block, tracking can be achieved.

[0036] During the control process, the controller 24 in the control system controls the two clutches by setting the time length, that is, the time point and the engagement duration of the first clutch 3, which affects the working time point and the working duration of the crushing device 4 and the dehydrator 6; when the gravity sensor 23 in the briquetting device 9 detects that the food waste in the material trough 22 reaches a certain weight, the first clutch 3 is released, so that the second clutch 8 is engaged, and the pressure rod 19 is pressed down through the threaded transmission, so that the food waste is compressed by the briquetting head 21 to form a food waste block. After a fixed interval, the motor 1 is reversed to reset the pressure rod 19, and then the food waste block is removed; after the briquetting is completed, the second clutch 8 is released, so that the first clutch 3 is engaged, so as to perform a cyclic operation.

[0037] The blade 26 has blade tips 38 evenly distributed along the circumference on the outside, and a through hole 42 is provided in the middle of the blade 26, which is a regular hexagonal through hole; the first scraper 31 and the second scraper 34 are both provided with threaded holes 43, and scraper heads 44 are evenly arranged on the first scraper 31 and the second scraper 34; the disc 27 on the driven shaft 36 is opposite to the blade 26 on the driving shaft 38, and the blade 26 on the driven shaft 36 is opposite to the disc 27 on the driving shaft 38; the number of teeth of the driven gear 35 is greater than the number of teeth of the driving gear 37.

The extrusion plate 57 is provided with an open slit.

[0039] In the middle of the screw rod 49 is the middle screw rod 63. The middle screw rod 63 compresses the kitchen waste. Due to the existence of the plastic sleeve 647, adhesion is reduced. The middle screw rod 63 includes an inner blade 645, a middle screw rod body 646, and a plastic sleeve 647. The outer part of the middle screw rod body 646 is provided with... The outer part of the inner blade 645 is sleeved with a plastic sleeve 647, and the plastic sleeves 647 cooperate with each other. The plastic sleeve 647 is of a C-shaped structure.

[0040] The above mechanical connection is generally in the form of a coupling connection. Other mechanical connection methods include interference fit connection, threaded connection, key connection, etc.

[0041] The present invention can complete the crushing, dehydration, and briquetting of kitchen waste, and use the numbers pressed on the kitchen waste briquettes to realize the tracking of kitchen waste. At the same time, combined with the above process, the controller realizes the intelligent control of the system. The power source of the present invention is a motor. After being decelerated by a reducer, two clutches are connected. By controlling the engagement time and engagement duration of the two clutches through the controller, the total duration of crushing and dehydration and the briquetting duration can be controlled, so as to automatically realize continuous kitchen waste treatment.
