[0020] The fruit screening container 11 includes an outer sieve tube 14, an inner sieve tube 15, a screen 16, a guide plate 18, and a partition 19. The outer sieve tube 14 and the inner sieve tube 15 are arranged in a concentric circle. The screen 16 and the guide plate 18 are respectively arranged in a spiral shape from top to bottom in the space between the outer sieve tube 14 and the inner sieve tube 15, and the top height of the screen 16 is lower than the top of the outer sieve tube 14 and the inner sieve tube 15, and the guide plate 18 is arranged parallel to the screen 1 6, the screen 16 is arranged from the upper end to the lower end to a plurality of screen hole areas 17 of different sizes, each screen hole area 17 of the screen 16 is provided with a screen hole, a partition 19 is provided at the end of the screen 16, a partition 19 is provided on the guide plate 18 corresponding to the end of each screen hole area 17, and a guide port 20 is provided on the inner screen tube 15 at each partition 19, and a cover plate 25 is detachably provided on the top of the outer screen tube 14, and the cover plate 25 corresponds to the top of the screen 16. A feed port is provided, which is connected to a feed pipe 23 to ensure that the picked fruits are transported to the screen 16 for screening, to prevent the fruits from falling, and to avoid the problem of being unable to enter the screen 16. The screening container 11 is provided with a fruit collecting bin 12 corresponding to the number of sieve hole areas 17. Each fruit collecting bin 12 is connected to a guide port 20 through a guide pipe 21. The two are arranged in an integrally formed structure. Each guide pipe 21 penetrates upward into the inner sieve tube 15 to connect the guide port 20. The top of the guide pipe 21 is sealed, and a notch is provided on the side wall corresponding to the guide port 20. The fruit enters the guide pipe 21 through the notch. A discharge port 22 is provided at the bottom of each fruit collecting bin 12, and the screened fruits are taken out from the discharge port 22; a partition 19 is provided to prevent fruits of different specifications from mixing together on the guide plate 18. When the fruit screened from the sieve hole area 17 rolls along the guide plate 18 to the partition 19, it is guided to be discharged from the guide port 20 to the fruit collecting bin 12.

[0021] The picking claws 4 include at least four claw rods arranged horizontally and equidistantly. The claw rods are round rods to prevent the peel from being scratched. The spacing between adjacent claw rods is smaller than the minimum fruit diameter. In order to improve the picking effect, each claw rod is provided with an L-shaped structure or an arc structure with an upward-curved front section.

[0022] The front section of the filter plate 3 on the top of the picking box 2 is arranged in a comb-like structure, and the spacing between adjacent comb teeth is not less than the maximum fruit diameter of the fruit; the middle and rear sections of the filter plate 3 on the top of the picking box 2 are arranged in a plate mesh structure, and the aperture of the plate mesh is smaller than the minimum fruit diameter of the fruit.

[0023] The filter plate 3 at the bottom of the picking box 2 is arranged in a comb-tooth structure, and the distance between adjacent comb teeth of the comb-tooth structure is less than the minimum fruit diameter of the fruit. This structure ensures that strip-shaped impurities and leaves can be discharged smoothly, solves the limitation that the hole-shaped structure cannot discharge impurities whose length or width is greater than the hole diameter, and prevents blueberry fruits from falling.

[0024] The height between the screen 16 and the guide plate 18 is not less than 3 cm, and the width of the screen 16 and the guide plate 18 is not less than 5 cm, ensuring that there is sufficient space for the blueberry fruits to roll.

[0025] At least three sieve hole areas 17 of different sizes are arranged in sequence from the upper end to the lower end of the sieve 16. The apertures of the sieve hole areas 17 are set according to the large, medium and small fruit diameter specifications of the fruits. The sieve holes of one sieve hole area 17 correspond to one fruit diameter specification, and the sieve hole aperture of the sieve hole area 17 at the upper part of the sieve 16 is smaller than the sieve hole aperture of the sieve hole area 17 connected to it below.

[0026] The screen 16 and the guide plate 18 surround the inner screen tube 15 for at least one and a half weeks. The diameter of the inner screen tube 15 is not less than 10 cm. The sieve hole area 17 on the screen 16 is guaranteed to have sufficient distance so that when the fruit rolls on the sieve hole area 17 of the screen 16, the fruit that meets the requirements can fall from the corresponding sieve hole area 17 to be screened.

[0027] Furthermore, the angle β between the screen 16, the guide plate 18 and the inner screen tube 15 is an acute angle, so that the fruit will not be blocked during the rolling process, and the fruit gathered at the partition 19 can be quickly discharged from the guide port 20 to the guide tube 21.

[0028] Furthermore, the inner wall of the outer screen tube 14 is provided with a spiral limiting convex line corresponding to the screen 16 and the guide plate 18, and the outer wall of the inner screen tube 15 is provided with a spiral limiting convex line corresponding to the screen 16 and the guide plate 18, which supports and fixes the screen 16 and the guide plate 18.

[0029] The filter plate 3 at the front section of the bottom of the picking box 2 is provided with an arc-shaped or sloped structure that is inclined upward.

[0030] The feeding pipe 23 is a flexible pipe, which is a corrugated pipe, a rubber pipe or a straight cloth bag.

[0031] Working mode of this utility model:

[0032] During the blueberry picking process, the worker wears the fruit screening container 11 on his body by means of the strap 24, holds the handle 10 on the top of the operating part 7, and inserts the picking claw 4 into the stem of the blueberry fruit to be picked, so that the blueberry fruit is stuck on the top of the picking claw 4. The worker then lifts the picking box 2 upward with force to pick the blueberry fruit. Then, the worker appropriately presses down the rear part of the picking box 2 to tilt it, so that the blueberry fruit rolls to the top of the picking box 2 below the material guide cover 5, and then falls into the picking box 2 through the gaps in the comb-shaped structure of the filter plate 3; impurities mixed in the blueberry fruit fall through the gaps in the comb-shaped structure of the filter plate 3 at the bottom of the picking box 2, and the blueberry fruit remains in the picking box 2;

[0033] Furthermore, in order to remove impurities more cleanly, during the picking process, the fan 6 is turned on to blow air into the picking box 2, and the wind is used to blow the impurities out from the gaps in the comb-shaped structure of the filter plate 3 at the bottom of the picking box 2, thereby increasing the filtering effect;

[0034] Subsequently, the picking box 2 is raised so that the height of the picking box 2 is higher than the feed port at the top of the screening mechanism 13, so that the blueberry fruits enter the screening mechanism 13 through the feeding pipe 23 for screening. Generally speaking, 5 to 20 blueberries can be picked at a time, so there is basically no blockage problem when the blueberry fruits are put into the present device for screening.

[0035] When the blueberry fruits reach the top of the screen 16, they roll along the screen 16 under the action of gravity. The fruits with the smallest diameter fall into the guide plate 18 from the first screen hole area 17, and the fruits with the second smallest diameter fall into the guide plate 18 from the second screen hole area 17. The blueberry fruits are screened in the order of falling according to the principle of small fruits first and large fruits later. When the blueberry fruits of each diameter fall to the guide plate 18 below the screen hole area 17, they will be gathered at the partition 19, enter the guide pipe 21 from the guide port 20, and then fall into the fruit collecting bin 12. After a certain amount is collected, the discharge port 22 is opened and the screened blueberry fruits can be taken out.

[0036] On the other hand, when carrying out large-scale picking and screening, in order to ensure the continuity of picking and screening, the unloading port 22 on each fruit collecting bin 12 is kept open throughout the screening process, and each unloading port 22 is connected to a bag, and the fruit is continuously discharged into the large-volume bag through the unloading port 22, thereby solving the defect of limited capacity of the fruit collecting bin 12 during large-scale collection and screening.
