[0035] The slurry adding assembly is connected with a mixed slurry assembly, which bears the functions of slurry storage and stirring, is driven by the slurry coating assembly, and prevents the slurry from depositing and stratifying, as shown in Figure 4 、 Figure 7 、 Figure 9 The mixed slurry assembly includes a barrel 23 for storing standby slurry, the barrel 23 is fixed on the chassis, and the barrel 23 is fixedly connected with a discharge valve through a pipeline on one side.

[0037] The stirring shaft 25 and the rotating shaft are connected through a bevel gear transmission. When the rotating shaft rotates, the stirring shaft 25 is driven to rotate around the mounting bracket through the bevel gear transmission, so as to realize synchronous transmission of power from the slurry coating assembly to the mixed slurry assembly.

The processor presets a slurry liquid level threshold value. When the detected liquid level is lower than the threshold value, the processor controls the valve on the suction pipe 19 to open, and the slurry adding assembly can extract more slurry from the barrel 23 to supplement the slurry coating pool 1. When the liquid level reaches the threshold value, the processor controls the valve to close, and stops supplementing the slurry, so as to ensure that the slurry in the slurry coating pool 1 always maintains the best working liquid level, and realizes automatic and accurate control of the slurry supplement.

[0040] The working process of the embodiment is as follows: Before use, a chaff coating device needs to be installed on one side of the recycling hood 5, and a conveyor needs to be connected to one side of the square hood 8. The poultry eggs are then arranged on the conveyor. The height of the feeding cup 17 is adjusted by sliding the adjustment frame 18. Lead-free crystal preserved egg slurry is injected into the coating tank 1 and the material bucket 23. The locking bolts are tightened to fix the slurry. The connection status of each component is checked to ensure that the drain valve is closed and the flexible tube is securely connected to the feeding hole.

[0041] When the power is connected and the switch of motor 3 is turned on, motor 3 drives the rotating shaft to rotate through the belt and pulley. The rotating shaft synchronously drives the actuating fork 4, rotating disk 14 and bevel gear to rotate, thereby linking the egg supply component, slurry addition component and slurry mixing component to start synchronously. When the rotating disk 14 rotates, it drives the outer lifting frame 11 and inner lifting frame 12 to rise and fall alternately: the baffle plate 9 rises to block subsequent eggs, and the discharge plate 10 falls to allow a single batch of eggs to fall into the coating tank 1 along the anti-sinking frame 7; then the discharge plate 10 rises to reset, and the baffle plate 9 rises to release the next batch of eggs, thus realizing intermittent automatic egg supply. The soft pad protects the eggs from damage. The actuating fork 4 rotates with the rotating shaft, on the one hand stirring the slurry in the coating tank 1, and with the anti-sinking frame 7 preventing the eggs from sinking, and on the other hand turning the eggs to roll in the slurry to ensure that the surface of the eggs is evenly coated with slurry. When the coated eggs move to the recycling hood 5 area, the slurry is recycled, and then the coated eggs are returned to the chaff coating equipment for chaff coating.

[0042] During the coating process, the outer lifting frame 11 lifts and lowers, causing the lower pressing frame 27 to squeeze the reset frame 21, driving the slurry feeding component to complete the "slurry suction-slurry discharge" reciprocating cycle, and stably replenishing a small amount of slurry to the coating tank 1; the ultrasonic level gauge 26 detects the slurry level in real time, and the processor automatically controls the valve on the suction pipe 19 to maintain the slurry level at the preset threshold, ensuring a stable coating effect.

[0043] During the coating process, the rotating shaft drives the stirring shaft 25 to rotate via the bevel gear. The spiral stirring blades and the stirring frame work together to stir the slurry in the material tank 23, preventing sedimentation and stratification, ensuring uniform concentration of the spare slurry, and continuously providing qualified slurry to the slurry feeding components.
