the dried fruits separated from the fruit receiving channel 220 are still at a certain distance from the water surface, so that the air flow in the air flow cavity 210C can absorb a certain amount of dust and branches and leaves to clean the dried fruits falling into the water.
If the air delivery section 233 is provided, the air flow discharged from the negative pressure section 231 enters the air delivery section 233, the guided air flow passing through the air delivery section 233 is output through the air delivery port 233A, and the direction of the output air flow is opposite to the moving direction of the dried fruits on the fruit receiving channel 220, so that dust and branches and leaves can be quickly separated, and the cleaning effect of the dried fruits is improved.
After the dried fruits smoothly fall into the water in the flotation cell 210A, the dried fruits which are shrunken float due to the self-gravity reduction, and the dried fruits in a floating state are formed in the bad fruit area 200A in a concentrated manner; while the dried fruits which are not partially shrunken but have a large water contact area and partially shrunken cannot be completely floated, can only be suspended in water, and are concentrated in the floating area 200B under the obstruction of the obstruction type guide plate 211 to form the dried fruits in a suspended state; the normal dried fruits sink and flow into the sinking notch 211A through the guide of the blocking guide plate 211, the dried fruits in a sinking state are deposited in the sinking area 200C after passing through the sinking notch 211A, and in order to facilitate the dried fruits to enter the second discharging channel 210C, a guide seat 212 is arranged at the bottom of the flotation cell 210A, and the top surface of the guide seat 212 is inclined towards the side where the second discharging channel 210C is located so as to guide the dried fruits, so that the dried fruits are piled around the second discharging channel 210C, and the dried fruits are discharged quickly.
At this time, the sinking notch 211A and the blocking type guide plate 211 act to block the dried fruits in the suspended state, so that the dried fruits in the suspended state are distinguished from the dried fruits in the suspended state, especially after the second discharging channel 210c is opened, because the water in the flotation cell 210A can be drained through the second discharging channel 250 after the second discharging channel 210c is opened, the sinking notch 211A can be blocked by the dried fruits with larger water contact area in the draining process, and therefore, the dried fruits in the suspended state cannot pass through the sinking notch 211A, even if only a small part of the dried fruits can not influence the whole quality of the selected fruits.
While the dried fruits in the floating state are discharged through the first discharge passage 240 when the first discharge passage 210b is opened (the first discharge passage 210b is opened before the second discharge passage 210 c), the dried fruits blocked on the blocking guide plate 211 are intensively cleaned later, and the dried fruits in the floating state can be used without being shrunken, so that the dried fruits need to be manually screened again.
In addition, as shown in fig. 8, an extending plate 213 is disposed on the side of the first discharging channel 210b, where the dried fruits enter, and the extending plate 213 is inclined upward, then under the suction force generated by the airflow conveying assembly 230, the dried fruits floating on the water surface are concentrated around the extending plate 213, and when the first discharging channel 210b is opened, the dried fruits floating on the water surface are guided by the extending plate 213 and then matched with the suction force, so that the dried fruits can be efficiently discharged, and incomplete discharge is avoided.
Figures 9 and 10 show a second embodiment of the invention,
in fig. 9, a connecting shaft 2111 is disposed in the obstructing type guiding plate 211, and the high end and the low end of the obstructing type guiding plate 211 rotate around the connecting shaft 2111, that is, the obstructing type guiding plate 211 is rotatably connected with the connecting shaft 2111, while the end portion of the inner wall of the flotation cell 210A corresponding to the connecting shaft 2111 is disposed with a guiding rail 211A, the connecting shaft 2111 can slide in the guiding rail 211A, the purpose is to form a horizontal adjusting assembly by matching the guiding rail 211A and the connecting shaft 2111, and the obstructing type guiding plate 211 in an inclined state is moved to a horizontal state under the action of the horizontal adjusting assembly, as shown in fig. 10, the obstructing type guiding plate 211 in a horizontal state is closely attached to the inner wall of the flotation cell 210A, so that the two ends of the obstructing type guiding plate 211 need to be set in a flexible state, no sinking notch 211A is present at this time, or the sinking notch 211A is closed, and thus the dry fruit in a suspended state cannot enter the sinking area 200C.
It should be noted that, the horizontal adjustment assembly may be formed by the connection shaft 2111 alone, and the guide rail 211A is provided to close the sinking slot 211A first, and then the obstructing guide plate 211 is rotated, so that the dry fruit in the suspended state is prevented from flowing into the sinking area 200C when the obstructing guide plate 211 is rotated, and thus the guide rail 211A has a trend approaching to the sinking slot 211A.
When the device is used, the first discharging channel 210b is opened to discharge the dried fruits in the floating state, meanwhile, the obstructing type guide plate 211 is adjusted to the horizontal state, after the obstructing type guide plate 211 is horizontal, the second discharging channel 210c is opened to discharge the dried fruits in the sinking state, and at the moment, the obstructing type guide plate 211 is restored to the inclined state again to discharge the dried fruits in the floating state through the second discharging channel 210 c.
The sinking notch 211A formed in the inclined state can screen dry fruits in a suspended state, and the screening principle is as follows:
under the pressure of the water flow, the dried fruits which are partially shrunken are compressed, then flow to the second discharging channel 210c through the sinking notch 211A and are discharged, but the dried fruits which are not shrunken and have larger water contact area cannot be compressed (indicating that the dried fruits have practical value) cannot be separated out through the sinking notch 211A, and finally the blocking type guide plate 211 is rotated to expand the sinking notch 211A, so that the separated dried fruits are discharged again, and the step of manual re-screening is reduced.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present invention, and are not intended to limit the invention, and that various changes and modifications may be made therein without departing from the spirit and scope of the invention as claimed.
