Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a device for screening and grading fresh roxburghii fruits. Background Art

[0002] Rosa roxburghii is a small wild shrub that blooms pink, red, or crimson flowers from April to June, with summer flowers and autumn fruits. The fruit is generally oblate, 2 to 4 cm in diameter, ripening from August to September. It is yellow, sometimes with a blush. The flesh is crisp and has a rich aroma when ripe. The skin is densely covered with small fleshy thorns, earning it the nickname "Roxburghii." The fruit is rich in vitamin C, earning it the nickname "King of Vitamin C." It contains 500 to 1000 mg of tannins, about 1 gram of acid, and generally about 4 grams of total sugar.

[0003] There are many products developed with sea buckthorn on the market, such as sea buckthorn beverages, dried sea buckthorn, sea buckthorn candied fruit, etc. Different products have different requirements for the size of sea buckthorn, so in order to make rational use of it, it is necessary to grade it according to size after picking. At present, the main method of grading is roller screen, but because the holes of the screen are dense, it is easy to scratch the surface of the sea buckthorn, and in the process of rolling, some sea buckthorns that are slightly larger than the diameter of the screen are easy to get stuck in the gap, affecting the subsequent screening. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a roxburghii fresh fruit screening and grading device to solve the technical problems in the above-mentioned background technology.

[0005] The technical solution of the utility model is:

[0006] A device for screening and grading fresh sea buckthorn fruit comprises a screening rotating cage, which consists of a cage body, a driving mechanism and a rejecting mechanism. The cage body consists of a plurality of parallelly arranged circular rings, which are fixed by beams distributed at equal angles. A truncated cone-shaped feed cover is welded to the inlet side of the cage body. The driving mechanism is fixed to the cage body and is used to transmit power to a power device to drive the cage body to rotate. The rejecting mechanism is used to cooperate with the cage body to reject objects stuck between the circular rings. The cage body is axially divided into a primary screening zone and a secondary screening zone, the primary screening zone is close to one side of the feed cover, the primary screening zone and the secondary screening zone respectively have a consistent circular ring spacing, and the circular ring spacing of the primary screening zone is larger than that of the secondary screening zone.

[0007] Furthermore, the driving mechanism includes a rotating shaft and a support ring. The support ring is welded to both ends of the cage and the junction of the first screening area and the second screening area. The rotating shaft is coaxially installed in the cage, and the inner side of the support ring is connected to the rotating shaft through the shaft frame.

[0008] Furthermore, a spiral guide plate is welded to the inner wall of the cage.

[0009] Furthermore, the rejecting mechanism includes a mounting plate arranged in parallel on the outside of the rotating cage and a plurality of comb teeth fixed on the side of the mounting plate. The comb teeth are made of rubber rods or tendon rods, which are cylindrical and inserted into the gaps of the rings one by one.

[0010] Furthermore, the insertion depth of the comb teeth is consistent with the cross-sectional diameter of the ring.

[0011] Furthermore, the minimum spacing between the rings in the first-level screening area is 31-33 mm, and the minimum spacing between the rings in the second-level screening area is 37-39 mm.

[0012] The utility model is beneficial in that:

[0013] The advantages of the present invention are that the traditional screen-type cage is replaced with a cage composed of circular rings, which is less likely to scratch the surface of the prickly pear and is less likely to get stuck. The screening speed is also faster, and the screening diameter can be adjusted by changing the spacing of the circular rings. A rejection mechanism is also provided. When the prickly pear that is stuck moves with the cage to the rejection mechanism position, it will be rejected by the comb teeth and returned to the cage. The comb teeth are made of rubber rods or tendon rods, which are elastic and will automatically spring open when encountering the crossbeams. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features described below in the various embodiments of the present invention may be combined with one another as long as they do not conflict with one another.

[0019] like Figure 1-3 As shown:

[0020] A device for screening and grading fresh sea buckthorn fruit comprises a screening rotating cage, which consists of a cage body 11, a driving mechanism, and a rejecting mechanism 5. The cage body 11 consists of a plurality of parallelly arranged circular rings 1, which are fixed by beams 2 distributed at equal angles. A truncated cone-shaped feed cover 3 is welded to the inlet side of the cage body 11. The driving mechanism is fixed to the cage body 11 and is used to transmit power to a power device to drive the cage body 11 to rotate. The rejecting mechanism 5 is used to cooperate with the cage body 11 to reject stuck objects between the circular rings 1. The cage body 11 is axially divided into a primary screening zone and a secondary screening zone, the primary screening zone being close to the feed cover 3. The primary and secondary screening zones respectively have consistent spacing between the circular rings 1, and the spacing between the circular rings 1 in the primary screening zone is larger than that in the secondary screening zone.

[0021] The utility model changes the traditional screen-type cage body 11 into a cage body 11 composed of a circular ring 1, so that the surface of the sea buckthorn is not easily scratched, is less likely to get stuck, and has a faster screening speed.

[0022] The utility model adjusts the screening diameter by changing the spacing between the rings 1, and is generally divided into three grades. The minimum spacing between the rings 1 in the first-level screening area is 31-33 mm, and the minimum spacing between the rings 1 in the second-level screening area is 37-39 mm. The first-level screening area is used for screening small fruits, which are mainly used for preparing sea buckthorn pulp or juice. The second-level screening area is used for screening medium fruits, which are mainly used for preparing sea buckthorn dried fruits. The remaining discharged fruits are large fruits, which are mainly used for preparing sea buckthorn preserved fruits.

[0023] However, it is inevitable that some sea buckthorns will still be stuck between the rings 1. The utility model is equipped with a removal mechanism 5, which includes a mounting plate 51 arranged in parallel on the outside of the rotating cage and a plurality of comb teeth 52 fixed on the side of the mounting plate 51. The comb teeth 52 are made of rubber rods or tendon rods and are cylindrical. They are inserted into the gaps of the rings 1 one by one. When the stuck sea buckthorns are rotated to the removal mechanism 5 position with the cage body 11, they will be removed by the comb teeth 52 and returned to the cage body 11. The comb teeth 52 are made of rubber rods or tendon rods and are elastic. When they encounter these positions of the beam 2, they will automatically bounce open. The insertion depth of the comb teeth 52 is consistent with the cross-sectional diameter of the ring 1.

[0024] The driving mechanism in the present invention adopts a rotating shaft 7 and a support ring 6. The support ring 6 is welded to both ends of the cage 11 and the junction of the first screening area and the second screening area. The rotating shaft 7 is coaxially installed in the cage 11, and the inner side of the support ring 6 is connected to the rotating shaft 7 through the shaft frame 71.

[0025] As an optimized solution, a spiral guide plate 4 is welded to the inner wall of the cage body 11. When the spiral guide plate 4 is not welded, the cage body 11 needs to be installed at an angle, with the inlet side higher than the outlet side. After welding the spiral guide plate 4, it can be installed horizontally, and at the same time, the internal sea buckthorn can be guided and rolled in an orderly manner, thereby increasing the accuracy of screening.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
