The holding box 9 moves forward until it moves below the quantitative discharge port 502 of the weighing area 5, then stops, and waits for the weighing receiving sweep 5063 to sweep the weighed lychees into the temperature holding box 9, and then the temperature is maintained. Case 9 continues to move forward under the transportation of running water table 6, and the next empty temperature holding case 9 continues to be transported to the quantitative discharge port 502 and waits for it. Get case cover 901 and cover on the temperature keeping box 9 of litchi, cover the temperature keeping box 9 of case cover 901 then and continue to next process.

Including a cleaning area 1, a water tank 101 is arranged above the cleaning area 1, and the water tank 101 is surrounded by a water tank tail plate 1013, a water tank side plate 101, a water tank slant plate 1015 and a water tank passing sand board 1014, and the water tank passing sand board 1014 is located at the bottom of the water tank 101, The tail plate 1013 of the water tank is perpendicular to the sand board 1014 of the water tank. Both sides of the tail plate 1013 of the water tank are respectively connected with two side plates 101 of the water tank. The other end of the side plate 101 of the water tank is connected with the inclined plate 1015 of the water tank. The bottom of 1015 is all connected with water tank crossing sand plate 1014, and the opposite side of water tank tail plate 1013 is an open mouth of water tank, and the open place is just facing the conveyer belt 1035 of cleaning delivery assembly 103, and the side plate 1011 of the water tank is provided with The water hole 1018, the tail plate 1013 of the water tank, the side plate 1011 of the water tank and the inclined plate 1015 of the water tank are all equipped with a plurality of bubble generators 1012. Sediment sedimentation tank 1017.

The bottom plate of the sedimentation tank 1017 is an arc-shaped plate, and the sedimentation tank 1017 is at an inclined angle.
