after screening is finished, the servo motor is controlled by the controller to rotate for a certain angle, so that the rear garbage tray rotates to a position right below the shredding box, and the garbage tray with residual large-particle garbage rotates upwards; in the process that the garbage tray with the residual large-particle garbage rotates upwards, the garbage tray always rotates around the hinged part under the action of the heavy object blocks, so that the garbage tray is always kept balanced when rotating out, and the garbage in the garbage tray is prevented from being poured out; the ratchet wheel prevents the garbage tray from shaking violently in the rotating process; on the other hand, when the garbage tray is positioned under the shredding box, the fixed clamping blocks hinged to the end parts of the annular rods naturally droop under the action of gravity, so that the fixed clamping blocks are flush with the annular rods, and the annular rods can be accommodated into the annular through holes; therefore, in the process of rolling out the garbage tray, the garbage tray rotates relative to the hinged position of the garbage tray and the rotating ring, so that the annular rod is accommodated in the annular through hole; when the garbage tray at the rear rotates to a position right below the shredding box, the garbage tray with residual large-particle garbage is just positioned at the leftmost side of the rotating ring, the servo motor stops rotating and transmits a signal to the controller, the controller controls the hydraulic cylinder to open the upper cover plate, the lower cover plate is in a covering state, and the garbage of the next batch is crushed; at the moment, the rubber cushion block at the other end of the annular rod props against the bottom of the garbage tray, so that the garbage tray is gradually inclined in the process of continuously upwards rotating along with the rotating ring; when the garbage tray is positioned at the leftmost side of the rotating ring, an operator can add new garbage to be treated into the garbage tray; when the garbage tray gradually rotates to the position above the slope groove, the inclination of the garbage tray is larger, garbage in the garbage tray falls into the slope groove under the action of gravity, and new garbage and the garbage which is not completely crushed in the previous batch are poured into the next batch of garbage for treatment; when the garbage tray rotates to a position which is on the right side of the highest point of the rotating ring, the gravity hammer pulls down the clamping rod under the action of gravity to enable the clamping rod to be separated from the ratchet wheel, the garbage tray can normally rotate clockwise around a hinge point, at the moment, under the action of the heavy object block, the garbage tray rotates clockwise gradually, when the clamping rod moves to the side wall of the ratchet wheel, the clamping rod cannot move continuously, the garbage tray stops rotating, and the garbage tray is in a horizontal state; in the rotation process of the garbage tray, the annular rod gradually extends out of the annular through hole; when the garbage tray stops rotating, the tail end of the annular rod is separated from the annular through hole, and the fixed clamping block is rotationally clamped outside the annular through hole due to the action of gravity, so that the annular rod is prevented from being accommodated into the annular through hole; when the garbage tray rotates to a position right below the shredding box again, the fixed clamping block naturally sags due to the action of gravity, so that the fixed clamping block is flush with the annular rod, and the annular rod can be retracted into the annular through hole again for next material receiving;
(2) oil and salt removal of garbage: the garbage fragments screened by the electric screen mesh fall into the concave conveying belt, and the concave conveying belt is conveyed forwards slowly to drive the garbage fragments to be conveyed forwards slowly; simultaneously, the liquid pump pumps the ethanol solution in the waste liquid tank into a cleaning and desalting oil pipe, and then the ethanol solution is sprayed out of a water permeable area in the middle of the concave conveying belt through a nozzle of the cleaning and desalting oil pipe to carry out oil and salt removing treatment on garbage on the concave conveying belt; the cleaned ethanol solution permeates through a middle water permeable area and then falls back into the waste liquid tank; after the garbage scraps are conveyed to the front end cavity section of the cleaning and oil removing pipe and enter the rear end cavity section, hot air sprayed from the rear end cavity section dries the oil-removed garbage;
(3) iron removal: when the dried garbage scraps enter the front end electromagnet part of the transmission part, ferromagnetic substances are attracted and attached to the belt by the electromagnet, and the ferromagnetic substances are gradually separated from the electromagnet area in the forward transmission process of the belt and finally fall into the iron material collecting box to complete the separation of the ferromagnetic substances in the garbage;
(4) composting and fermenting: and non-ferromagnetic garbage is conveyed on the concave conveying belt and finally falls into the composting system for composting and fermentation.
The invention has the beneficial effects that: the invention realizes the full pretreatment of the kitchen waste, completely crushes the treated waste, is beneficial to the subsequent aerobic composting process, greatly shortens the composting time, obviously improves the effect and realizes the recycling of the kitchen waste.
