Description

Technical Field

[0001] The utility model relates to the technical field of peanut seed separation, in particular to seed size separation equipment. Background Art

[0002] Before peanut seeds are sown, in order to ensure the planting quality, it is usually necessary to select seeds with full and uniform grains for sowing, and to remove seeds with too many wrinkles, slightly flat, bitten by insects or damaged on the outside by screening. For example, the patent document with application number CN201921686888.3 discloses a new type of vibrating screening equipment for water spinach seeds. By setting a flipping mechanism, the screening frame is flipped up and down in a vertical plane, so that the internal seeds are flipped more thoroughly and the screening speed is improved.

[0003] However, in the above-mentioned similar schemes, the peanut seeds need to be rubbed and rolled during grading. Since the peanut skin is relatively fragile, the seed skin will be damaged during the friction process, causing it to fall off, thereby affecting the survival rate of the seeds. In addition, when filtering the shelled peanuts, the size of the shelled peanuts and the peanut seeds is different, so the filter needs to be replaced during filtering.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a seed size separation device is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a seed size separation device, which solves the above-mentioned similar solutions proposed in the above-mentioned background technology. Peanut seeds need to be rubbed and rolled during grading. Since the peanut skin is relatively fragile, the seed skin will be damaged during the friction process, causing it to fall off, thereby affecting the survival rate of the seeds. In addition, when filtering shelled peanuts, due to the different sizes of shelled peanuts and peanut seeds, the filter screen needs to be replaced during filtering.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a seed size separation device, comprising a shell, a grading component and a conversion component, the grading component is located on the inner side of the shell, and the grading component comprises a connecting rod, a rubber pad, a first support disk and a second support disk, and the first support disk is fixed to the right end of the inner side of the shell, the second support disk is fixed to the left end of the first support disk, and the connecting rod is penetrated between the first support disk and the second support disk, and the rubber pad is bonded to the center of the outer side of the connecting rod, the conversion component is located on the inner side of the shell, and the conversion component comprises a servo motor, a rotating shaft and an arc plate, the servo motor is fixed to the left end of the shell, and the output end of the servo motor is connected to the rotating shaft, and two groups of arc plates are provided on the outer edges of the first support disk and the second support disk.

[0007] Furthermore, a feed port is provided through the right end of the shell, and the feed port is located at the center of the first supporting plate.

[0008] Furthermore, the diameter of the first support plate is smaller than that of the second support plate, and a plurality of groups of limiting holes are provided at the edges of the first support plate and the second support plate, and two groups of through holes are provided at the upper and lower sides of the second support plate.

[0009] Furthermore, the rotating shaft is located outside the first supporting plate and the second supporting plate, and the servo motor forms a rotating structure with the grading assembly through the rotating shaft.

[0010] Furthermore, an interlayer is provided between the shell and the grading assembly, a support plate is fixed below the shell, and the connecting rod gaps on both sides of the arc plate are different.

[0011] Furthermore, a first outlet is provided through the right side of the support plate, and a second outlet is provided through the left side of the support plate.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] like Figures 1 to 5 As shown, a seed size separation device includes a shell 1, a grading component 3 and a conversion component 4. A feed port 2 is provided at the right end of the shell 1, and the feed port 2 is located in the center of a first support plate 303, which is used to add peanut seeds from the bottom to the inside. The falling impact of the peanut seeds can be reduced in the middle part. The grading component 3 is located on the inner side of the shell 1, and the grading component 3 includes a connecting rod 301, a rubber pad 302, a first support plate 303 and a second support plate 304. The first support plate 303 is fixed to the right end of the inner side of the shell 1, and the second support plate 304 is fixed to the left end of the first support plate 303 for supporting the grading component 3. A connecting rod 301 is provided between the first support plate 303 and the second support plate 304. The diameter of the support plate 303 is smaller than that of the second support plate 304, so that the gap at the right end of the connecting rod 301 is smaller than the gap at its left end, so that when the peanut seeds roll along the connecting rod 301, the peanut particle size can be graded, and the edges of the first support plate 303 and the second support plate 304 are penetrated with a plurality of groups of limiting holes 331 for installing and fixing the connecting rod 301, and the upper and lower sides of the second support plate 304 are penetrated with two groups of through holes 341, and the peanuts with full particles and large volume roll to the end of the connecting rod 301 and flow out from the through holes 341, thereby avoiding mutual friction caused by shaking, and protecting the peanut epidermis to avoid the seed epidermis from falling off, thereby improving the survival rate of the peanut seeds.

[0023] A rubber pad 302 is bonded to the center of the outer side of the connecting rod 301, which can reduce the impact of the peanut seeds when they fall, so as to further protect the epidermis of the peanut seeds. A first outlet 6 is provided through the right side of the support plate 8, and a second outlet 7 is provided through the left side of the support plate 8. By placing storage boxes at different outlets, the peanut seeds can be screened, and different varieties of peanut seeds can be screened into different collection boxes.

[0024] The conversion component 4 is located on the inner side of the shell 1. The conversion component 4 includes a servo motor 401, a rotating shaft 402 and an arc plate 403. The servo motor 401 is fixed to the left end of the shell 1, and the output end of the servo motor 401 is connected to the rotating shaft 402. Two groups of arc plates 403 are arranged on the outer edges of the first support disk 303 and the second support disk 304 to prevent seeds from falling into the interlayer from both sides. Because the rotating shaft 402 is located on the outer sides of the first support disk 303 and the second support disk 304, the servo motor 401 forms a rotating structure with the grading component 3 through the rotating shaft 402. Because the gaps of the connecting rods 301 on both sides of the arc plate 403 are different, the servo motor 401 drives the grading component 3 to rotate, so that the end with the larger gap of the connecting rod 301 is located at the bottom of the device, so that the aperture of the filtration point can be changed without disassembling the filter screen, so that it is suitable for filtering peanuts in shells, which is conducive to improving the applicability of the device. An interlayer 5 is arranged between the shell 1 and the grading component 3, and a support plate 8 is fixed below the shell 1.

[0025] In summary, when the seed size separation device is used, first, the peanut seeds enter the shell 1 from the feed port 2, and then the peanut seeds fall to the upper right end of the connecting rod 301. Since the rubber pad 302 is arranged on the outer side of the connecting rod 301, the rubber pad 302 reduces the impact force of the peanut seeds when they fall, and slides to the left along the right end of the connecting rod 301. Since the gap at the right end of the connecting rod 301 is small, the peanut seeds that are shriveled or bitten by insects in the peanut seeds fall directly from the right end of the connecting rod 301 into the interlayer, and the remaining seeds continue to slide to the left along the connecting rod 301. When the gap between the connecting rods 301 is larger than the seed body, the peanut seeds are separated. When the peanut seeds are accumulated, the smaller peanut seeds will pass through the connecting rod 301 and fall into the interlayer 5, and roll along the inner wall of the shell 1 to the second outlet 6, and fall into the storage box from the second outlet 6, while the seeds with full grains and larger volume move to the leftmost end of the connecting rod 301 and flow out from the through hole 341, so as to classify the grades of the peanut seeds. When the screening material needs to be replaced, the servo motor 401 is started, and the servo motor 401 drives the rotating shaft 402 and the second supporting plate 304 to rotate 180 degrees, so that the connecting rod 301 with a larger gap is located at the bottom, so as to adapt to peanut seeds of different sizes.
