Description

Technical Field

[0001] The utility model relates to the field of walnut processing and storage equipment, in particular to a two-way color sorting and storage device for walnuts. Background Art

[0002] "First-class" and "second-class" are terms used in agricultural product grading, typically referring to batches separated by size or quality. In walnut processing, "first-class" typically refers to larger or higher-quality walnuts, while "second-class" refers to the next best batch. To achieve efficient walnut separation, specialized separation devices are typically used to grade walnuts based on size, weight, or appearance. The diversion process typically employs methods such as air jet valves to direct screened and inspected walnuts to different collection areas, ensuring that first-class and second-class walnuts are collected separately, enabling automated color sorting and large-scale production of walnuts.

[0003] Currently, guide boxes are often used to guide the falling walnuts into open frames to receive and temporarily store the second-pass walnuts after color sorting. The walnuts are not cushioned during their fall, which can lead to degradation due to impact and breakage. The walnuts are not stored in large quantities in the open frames, and they tend to pile up at the same angle, causing a backlog and cracking of the walnuts at the bottom. Furthermore, when a large number of walnuts are stored together, the internal air circulation is poor, and the walnuts are highly humid and susceptible to moisture, which can cause the walnuts to mold from the inside out, seriously affecting their use and commercial value. The storage process requires constant manual handling and replacement of the open frames, increasing labor costs. Utility Model Content

DETAILED DESCRIPTION

[0029] Example 1

[0030] like Figures 1-8 As shown, a two-way color sorting and storage device for walnuts is provided. A storage barrel 1 is arranged in a storage barrel shell 2. A material receiving cylinder 3 is provided at the upper end of the storage barrel 1, and the material receiving cylinder 3 is connected to the storage barrel shell 2. A collecting hopper 4 is provided between the lower end of the material receiving cylinder 3 and the upper end of the storage barrel 1. A driving device drives the collecting hopper 4 to rotate around the axis of the storage barrel 1. The collecting hopper 4 is an eccentric cone with a quantitative valve 5 at its vertex. A plurality of partition plates 6 are provided in the storage barrel 1, and the quantitative valve 5 opens toward the partition plate 6 according to a certain rule.

[0031] The present application adopts a semi-sealed storage barrel 1 structure, which is controlled by a metering valve 5 to open and close, thereby realizing light-proof and dry storage of walnuts. The separated two-way walnuts enter the collecting hopper 4 from the receiving barrel 3 to realize initial buffering. After accumulating a certain weight, they are opened by the metering valve 5 and lowered into the storage barrel 1. The metering valve 5 is set at the top of the rotating eccentric cone collecting hopper 4, and cooperates with the specific opening angle of the metering valve 5 to make the walnuts fall onto the partition plate 6 when entering the storage barrel 1, thereby realizing secondary buffering. At the same time, the partition plate 6 realizes height partitioning in the barrel, reducing the pressure on the bottom walnuts and reducing the possibility of impact and backlog breakage of the walnuts entering the storage device.

[0032] In the preferred embodiment, the outer ring of the bottom of the eccentric cone of the collecting hopper 4 is provided with a gear ring 401, and the output shaft of the reduction motor 7 is provided with a driving gear 8, which is engaged with the gear ring 401. The reduction motor 7 drives the collecting hopper 4 to rotate between the storage barrel 1 and the receiving barrel 3.

[0033] The reduction motor 7 drives the collecting hopper 4 to rotate at a constant speed, so that the walnuts are evenly scattered to the inner circumference of the storage barrel 1 when the walnuts are quantitatively placed, thereby reducing the phenomenon of serious accumulation at a certain point.

[0034] In the preferred embodiment, the inner ring of the gear ring 401 is further provided with a rotation groove 402 , which is symmetrically arranged on the upper and lower surfaces of the gear ring 401 . The collecting hopper 4 is rotatably connected to the upper end of the storage barrel 1 and the lower end of the receiving barrel 3 through the rotation groove 402 .

[0035] Specifically, the collecting hopper 4 covers the opening above the storage barrel 1, and rotates tightly through the rotating groove 402 on the lower surface of the gear ring 401, and limits its movement in the horizontal plane. The lower end of the upper receiving barrel 3 is pressed into the rotating groove 402 on the upper surface of the gear ring 401, limiting the movement of the collecting hopper 4 in the vertical direction, realizing a tight connection between the receiving barrel 3 and the storage barrel 1, and preventing external dirt or moisture from entering the storage barrel 1.

[0036] In the preferred embodiment, the metering valve 5 includes a feed pipe 501, a cover plate 502, a servo motor 503 and a load sensor 504. The lower end of the feed pipe 501 is rotatably connected to the cover plate 502 via a hinge 505. The servo motor 503 is fixed to the feed pipe 501, and its output shaft is connected to the hinge 505 to drive the cover plate 502 to rotate.

[0037] The load sensor 504 is set in the cover plate 502 and is used to detect the weight of the two walnuts in the discharge pipe 501.

[0038] Specifically, a rated parameter is set for the load sensor 504. When walnuts under the parameter weight enter the storage barrel 1 at one time, it is not easy to cause jamming, squeezing and impact, and it is convenient for counting and statistics; when the load sensor 504 detects that the cover 502 is subjected to the rated pressure, the servo motor 503 controls the hinge 505 to rotate, open the cover 502, and realize the automatic quantitative entry of the buffered two-way walnuts into the storage device.

[0039] In the preferred embodiment, the partition plate 6 is an annular sector plate, the length of which is adapted to the offset length of the eccentric cone vertex of the collecting hopper 4, and the partition plate 6 points to the center of the storage barrel 1 and is tilted downward at a certain angle;

[0040] The partition plates 6 are evenly arranged in a double helix structure in the storage barrel 1. The inclined surface of the partition plates 6 allows the two-way walnuts that fall on it to roll to the bottom of the storage barrel 1 after being buffered and not to stay there. The evenly arranged partition plates in the double helix divide the internal weight evenly in the circumferential direction, ensuring that different layers will not be crushed.

[0041] In a preferred embodiment, the hinge 505 is positioned near the center of the storage bucket 1, so that when the cover 502 is opened at a certain angle, its end point points to the surface of the partition 6. The angle at which the cover 502 is opened ensures that the end point of the walnut's falling trajectory always lies on the surface of the partition 6, ensuring that the two walnuts are cushioned when entering the storage bucket 1 and reducing the risk of impact and breakage.

[0042] In the preferred embodiment, a gap is left between the bottom end of the storage bucket 1 and the bottom end of the storage bucket shell 2, and the bottom end of the storage bucket 1 is connected to the inner bottom surface of the storage bucket shell 2 through a plurality of supporting columns 9 around the circumference;

[0043] The bottom plate of the storage barrel 1 is evenly provided with a plurality of small holes, the diameter of which is smaller than the minimum diameter of the second-way walnut.

[0044] The walnuts at the bottom of the storage barrel 1 are the most likely place for accumulation of humid gas. By setting small holes at the bottom, ventilation of the walnuts stored inside can be guaranteed. The storage barrel shell 2 is sleeved on the storage barrel 1 so that the vent at the bottom of the storage barrel 1 is not directly exposed to the outside world, ensuring the hygiene of the walnut storage environment. The support column 9 provides support for the storage barrel 1.

[0045] In the preferred embodiment, a dehumidifying and drying device 10 is installed at the bottom end of one side of the storage barrel shell 2. This device is used to keep the walnuts dry through the small holes in the bottom plate of the storage barrel 1. The ventilation opening at the bottom of the storage barrel 1 is not directly exposed to the outside world. The dehumidifying and drying device 10 utilizes the air circulation between the storage barrel shell 2 and the storage barrel 1 to indirectly remove moisture from the storage barrel 1, ensuring a dry storage environment for the walnuts.

[0046] In the preferred embodiment, a discharge chute 11 is provided between one side of the bottom end of the storage bucket 1 and the storage bucket shell 2. This chute 11 is a circumferentially closed pipe with a discharge door 101 and a discharge door 201 at its ends, respectively, located on the side walls of the storage bucket 1 and the storage bucket shell 2. The provision of discharge chute 11 facilitates the walnuts' flow out of the storage bucket 1 by gravity, making them easier to access. The dual-opening and closing doors reduce external influences on the storage environment within the storage bucket 1 during access.

[0047] In the preferred embodiment, the receiving barrel 3 is a curved pipe with a circular cross-section, with its top opening facing in the direction that matches the trajectory of the separated walnuts. The precisely oriented, large opening of the receiving barrel 3 enables the storage device to accurately receive the separated walnuts. The curved surface guides walnuts that reach the barrel wall, allowing them to fall into the collection hopper 4.

[0048] The above embodiments are merely preferred technical solutions of the present invention and should not be construed as limiting the present invention. The scope of protection of the present invention shall be the technical solutions set forth in the claims, including equivalent alternatives to the technical features of the technical solutions set forth in the claims. Equivalent alternatives and improvements within this scope are also within the scope of protection of the present invention.
