Description

Technical Field

[0001] This patent relates to the chestnut field, specifically a chestnut screening device. Background Art

[0002] Chestnut is a deciduous tree of the genus Castanea in the family Fagaceae, with thick cylindrical stems and branches; the surface is dark green with fine longitudinal lines and small hairs; the leaves are mostly curled, with short petioles, oval leaves, yellow-brown surfaces, and young leaves covered with fine hairs; the flowers are small, light yellow, with large corollas and yellow stigmas; the flowering period is May-June; the fruiting period is July-August. After picking, chestnuts need to be screened by size to distinguish between fine and ordinary ones, which requires a chestnut screening machine. However, during the use of the current chestnut screening machine, the small chestnuts screened in pairs will accumulate in the holes on the chestnut screening plate, causing the holes to be blocked. The falling of small hairs on the surface of the chestnuts will also cause the holes to be blocked, thus affecting the problem of chestnut screening. Utility Model Content

[0022] A dredging structure 4 is installed in the tank body 1, and the dredging structure 4 includes a first servo motor 401, a rotating shaft 402, an electric push rod 403, a trapezoidal plate 404 and a round shaft 405;

[0023] The first servo motor 401 is installed in the tank body 1, and the first servo motor 401 is powered on to work. The rotating shaft 402 is installed on the output shaft of the first servo motor 401, and the electric push rod 403 is installed on the rotating shaft 402. The electric push rod 403 is powered on to work. The electric push rod 403 is perpendicular to the first servo motor, the trapezoidal plate 404 is installed on the output end of the electric push rod 403, and the circular shaft 405 is installed on the trapezoidal plate 404. The circular shaft 405 corresponds to the holes on the chestnut sieve plate 8 one by one, and the outer diameter of the circular shaft 405 is smaller than the hole diameter on the chestnut sieve plate 8.

[0024] A rotating structure 10 is installed in the feed pipe 2, and the rotating structure 10 includes a horizontal plate 11, a vertical rod 12, a second servo motor 13, a rotating plate 14 and a brush 15;

[0025] The horizontal plate 11 is installed in the feed pipe 2, the vertical rod 12 is installed on the horizontal plate 11, the second servo motor 13 is installed on the vertical rod 12, the second servo motor 13 is powered on to work, the rotating plate 14 is installed on the output shaft of the second servo motor 13, and the brush 15 is installed on the rotating plate 14. The brush 15 is a steel brush, and the brush 15 contacts the chestnut screen plate 8.

[0026] A card slot 16 is provided on the feed pipe 2. There are two card slots 16. The card slots 16 are symmetrically distributed on both sides with the center line of the feed pipe 2 as the center. The two sides of the cross plate 11 are respectively inserted into the card slots 16. The cross plate 11 is placed in the card slots 16, so that the cross plate 11 can be limited in the feed pipe 2, otherwise it can be removed.

[0027] A bolt 17 is installed on the output shaft of the second servo motor 13, and a threaded hole 18 is opened on the rotating plate 14. The bolt 17 is sleeved in the threaded hole 18. The threaded hole 18 on the rotating plate 14 is screwed onto the bolt 17 on the output shaft of the second servo motor 13, so that the rotating plate 14 is installed on the output shaft of the second servo motor 13, and vice versa, it can be disassembled.

[0028] An annular receiving plate 7 is installed outside the tank body 1, and the annular receiving plate 7 is placed outside the first outlet 3. The high-quality chestnuts are discharged into the annular receiving plate 7 through the first outlet 3 and collected manually. A convex plate 6 is installed inside the tank body 1, and the convex plate 6 is placed in the second outlet 5. The inferior chestnuts fall on the convex plate 6 and are discharged through the second outlet 5.

[0029] An annular plate 9 is installed in the tank body 1, and a chestnut sieve plate 8 is placed in the tank body 1. The outer wall of the chestnut sieve plate 8 fits tightly with the inner wall of the tank body 1, and the friction between the chestnut sieve plate 8 and the tank body 1 is greater than the force of the circular shaft 405 extending into the hole on the chestnut sieve plate 8 to clear the chestnuts, thereby avoiding lifting the chestnut sieve plate 8. The chestnut sieve plate 8 is placed on the annular plate 9, and the chestnut sieve plate 8 is movable and detachable.

[0030] When the present invention is working, the chestnut sieve plate 8 is fed into the tank body 1 through the first outlet 3 and placed on the annular plate 9 (the annular receiving plate does not hinder the installation of the chestnut sieve plate), so that the horizontal plate 11 is inserted into the slot 16 on the feed pipe 2, and the vertical rod with the second servo motor 13 extends into the tank body 1, and through the first outlet 3, the threaded hole 18 on the rotating plate 14 is screwed on the bolt 17 on the output shaft of the second servo motor 13, so that the rotating plate 14 is installed on the output shaft of the second servo motor 13. When working, the chestnuts are discharged into the tank body 1 through the feed pipe 2, and the chestnuts fall on the chestnut sieve plate 8. At this time, the output shaft of the second servo motor 13 drives the brush 15 on the rotating plate 14 to rotate, so that the chestnuts are quickly screened through the chestnut sieve plate 8, and the fine chestnuts are discharged into the annular receiving plate 7 through the first outlet 3 and collected manually, while the inferior chestnuts pass through the chestnut sieve plate 8. The hole falls on the convex plate 6 and is discharged through the second outlet 5. After the feeding is stopped regularly, the first servo motor 401 is put into operation, and the output shaft of the first servo motor 401 drives the rotating shaft 402 to rotate 180 degrees, and the rotating shaft 402 drives the trapezoidal plate 404 to flip 180 degrees through the electric push rod 403. At this time, the round shaft 405 rushes up, and the output end 403 of the electric push rod 403 drives the trapezoidal plate 404 to move toward the chestnut sieve plate 8. The round shaft 405 can dredge the chestnuts stuck in the holes of the chestnut sieve plate 8 and the fluff that has fallen off the chestnuts. After dredging, the output shaft of the first servo motor 401 drives the round shaft 405 to return to the original path (the self-locking function of the output shaft of the first servo motor 401 stops, so that the position of the round shaft 405 can be fixed, and the round shaft 405 returns to the original path to prevent the wiring of the electric push rod 403 from hindering the rotation).

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
