Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural seed production technology, and specifically relates to a sorting device for agricultural seed production. Background Technology
[0002] Seed sorting is a crucial step in agricultural seed production, directly impacting seed quality and subsequent planting outcomes. Existing seed sorting devices typically employ fixed-aperture screens or airflow sorting technology. While these methods can achieve seed sorting to some extent, they also have significant limitations. For agricultural seeds, screens or airflow sorting are the primary methods of sorting.
[0003] Traditional sieve sorting devices have fixed apertures that cannot be adjusted to accommodate different seed sizes. This means that the same device cannot effectively sort different types of seeds, resulting in low sorting efficiency and potentially damaging the seeds.
[0004] While airflow sorting can separate seeds based on weight and density, its effectiveness is less than ideal for seeds of similar size but with minimal weight differences. Furthermore, airflow sorting places high demands on seed shape and surface characteristics, limiting its applicability.
[0005] Existing devices typically only sort seeds of specific types and cannot flexibly handle different types and sizes of seeds. This necessitates the purchase of multiple devices in agricultural production, increasing costs and space requirements. Therefore, this invention proposes a sorting device for agricultural seed production to address this issue. Utility Model Content
[0006] The purpose of this invention is to provide a sorting device for agricultural seed production that can solve the above-mentioned technical problems.
[0007] The specific technical solution adopted by this utility model is as follows:
[0008] This utility model provides a sorting device for agricultural seed production, including a frame and a screening mechanism disposed within the frame. The frame and the screening mechanism are arranged with their sides tilted at 3°, one high and one low. A shield covering the screening mechanism is disposed within the frame. A feed hopper communicating with the interior is disposed on the shield. A discharge plate is disposed within the frame. The discharge plate is tilted and disposed at an opening formed on the bottom surface of the shield. A blower frame is disposed below the discharge plate. A blower communicating with the blower frame is installed within the frame.
[0009] An inclined plate is provided inside the frame, located below the blower frame, and a baffle assembly for adjusting the interception of seeds is provided on the upper side of the inclined plate.
[0010] The screening mechanism includes a rotating shaft rotatably mounted on a frame. A turntable fixedly connected to the rotating shaft is provided on one side of the shield. Multiple outer plates spaced 15° apart are provided on the outer periphery of the turntable. Two cross-shaped rotating rings located inside the multiple outer plates are provided on the rotating shaft. Multiple inner adjustment plates close to the inner side of the outer plates are provided on the outer periphery of the two cross-shaped rotating rings. The multiple inner adjustment plates are distributed at 15° intervals with the rotating shaft as the center. A reinforcing ring is provided on the other side of the multiple outer plates. A limiting component for adjusting the rotation angle of the inner adjustment rings is provided on the rotating shaft.
[0011] In the above-mentioned sorting device for agricultural seed production, during use, the fastening nuts on the limiting assembly are loosened, and then the cross-shaped rotating ring is rotated to drive multiple inner adjusting plates to rotate. This adjusts the overlapping area between the inner adjusting plates and the outer plates, thereby adjusting the channel between adjacent outer plates to match the agricultural seeds. Then, the fastening bolts are tightened to align the cross-shaped rotating ring with the corresponding pin holes on the pin hole disc. Finally, the drive motor and blower are turned on, causing the drive motor to drive the turntable, outer plates, and inner adjusting plates on the cross-shaped rotating ring. The plates rotate synchronously, and the seeds to be sorted are poured into the shielding frame through the feed hopper. The rotating outer plate evenly distributes the poured seeds. As the seeds enter the outer plate, the rotating outer plate and the rotating cross ring screen screen the seeds. The seeds that fall through the outer plate and the inner adjusting plate roll through the discharge plate, and the air blown by the blower blows away the impurities mixed in with the fallen seeds. The seeds are then intercepted by the intercepting mesh frame and fall onto the inclined plate. In this way, impurities are removed from the seeds sorted by the screening mechanism.
[0012] Preferably, the limiting component includes a pin hole plate disposed on the rotating shaft near one of the cross rotating rings. The pin hole plate is formed with a plurality of pin holes. Two fastening bolts are disposed on the cross rotating ring on the rotating shaft near the pin holes through formed sleeve holes. The two fastening bolts are disposed in two horizontally symmetrical pin holes.
[0013] Preferably, a drive motor is mounted on one side of the frame, the output shaft of the drive motor is connected to one side of the rotating shaft, and a discharge hole is formed on the other side of the frame corresponding to the inner bottom surface of the ring formed by the shield and multiple inner adjustment plates. An adjustment hole for adjusting the limiting component is also formed on the other side of the frame.
[0014] Preferably, the baffle assembly includes a baffle disposed within a frame, a central rod limited by a nut on the frame, the central rod corresponding to the upper side of the inclined plate, the lower side of the baffle being movably disposed on the central rod, and an intercepting mesh frame corresponding to the lower side of the air blowing frame outlet direction disposed within the frame, the intercepting mesh frame being disposed on the upper side of the rotating plate.
[0015] Preferably, both sides of the frame are provided with arc-shaped holes, and positioning rods that are limited by nuts are movably fitted in the two arc-shaped holes. The positioning rods are movably fitted on the upper side of the rotating plate.
[0016] Preferably, four centrally symmetrical stirring plates are arranged between the two cross-shaped rotating rings.
[0017] The beneficial effects are:
[0018] 1. This utility model, through the combined use of the outer plate, inner adjusting plate and limiting component in the screening mechanism of the shield, enables the limiting component to adjust the intersecting area of the inner adjusting plate and the outer plate, so that the channel after adjustment of the outer plate and the inner adjusting plate can be used to sort different agricultural seeds.
[0019] 2. This utility model, through the combined use of a screening mechanism, a baffle assembly, a blowing frame, and a blower, enables the airflow from the blowing frame after passing through the discharge plate to remove impurities from the screened seeds. The baffle assembly can adjust the interception angle according to the weight of different seeds, thereby improving the versatility of the device and making it convenient for removing impurities after sorting different agricultural seeds.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0027] like Figure 1-4 As shown, a sorting device for agricultural seed production includes a frame 1 and a screening mechanism 3 disposed within the frame 1. The frame 1 and the screening mechanism 3 are set at an angle of 3° with one side higher than the other. A shield 2 is disposed inside the frame 1 to cover the screening mechanism 3. A feed hopper communicating with the interior is disposed on the shield 2. A discharge plate 4 is disposed inside the frame 1. The discharge plate 4 is inclinedly disposed at an opening formed on the bottom surface of the shield 2. A blower frame 6 is disposed below the discharge plate 4. A blower 5 communicating with the blower frame 6 is installed inside the frame 1.
[0028] An inclined plate 7 is provided inside the frame 1, located below the blower frame 6, and a baffle assembly for adjusting the interception of seeds is provided on the upper side of the inclined plate 7.
[0029] The screening mechanism 3 includes a rotating shaft 31 rotatably mounted on the frame 1. A turntable 32 fixedly connected to the rotating shaft 31 is provided on one side of the shield 2. Multiple outer plates 33 spaced 15° apart are provided on the outer periphery of the turntable 32. Two cross-shaped rotating rings 35 located inside the multiple outer plates 33 are provided on the rotating shaft 31. Multiple inner adjustment plates 36 close to the inner side of the outer plates 33 are provided on the outer periphery of the two cross-shaped rotating rings 35. The multiple inner adjustment plates 36 are distributed at 15° intervals with the rotating shaft 31 as the center. A reinforcing ring 34 is provided on the other side of the multiple outer plates 33. A limiting component for adjusting the rotation angle of the inner adjustment rings is provided on the rotating shaft 31.
[0030] As an optional implementation, the limiting component includes a pin hole disk 38 disposed on the rotating shaft 31 near one of the cross rotating rings 35. The pin hole disk 38 is formed with multiple pin holes. Two fastening bolts 39 are disposed on the cross rotating ring 35 on the rotating shaft 31 near the pin holes through formed sleeve holes. The two fastening bolts 39 are disposed in two horizontally symmetrical pin holes. The feed hopper corresponds vertically to the rotating disk 32 and the other cross rotating ring 35. The length of the discharge plate 4 is set to correspond to the cross rotating ring near the rotating disk 32. In this way, the seeds passing through the feed hopper can be evenly entered on the rotating outer plate 33, and then sorted by the alternation of the inner adjusting plate 36 and the outer plate 33.
[0031] Furthermore, a drive motor 310 is installed on the side of the frame 1, and the output shaft of the drive motor 310 is connected to one side of the rotating shaft 31. The other side of the frame 1 is provided with a discharge hole 13 corresponding to the inner bottom surface of the ring formed by the shield 2 and multiple inner adjustment plates 36. The other side of the frame 1 is also provided with an adjustment hole 14 for adjusting the limiting component. This arrangement allows the seeds intercepted by the inner adjustment plates 36 and outer plates 33 on the screening mechanism 3 to be discharged through the discharge hole 13, thereby ensuring the circulation of the screening mechanism 3. The adjustment hole 14 facilitates the adjustment of the tightness of the fastening bolts 39 on the limiting component, thereby facilitating the adjustment of the overlapping area between the inner adjustment plates 36 and the outer plates 33, and making it convenient to adjust for different seeds.
[0032] See attached document Figure 2 The baffle assembly includes a baffle set inside the frame 1. A central rod 9, which is limited by a nut, is fitted on the frame 1. The central rod 9 corresponds to the upper side of the inclined plate 7. The lower side of the baffle is movably fitted on the central rod 9. An intercepting net frame 11 is set inside the frame 1, which corresponds to the lower side of the outlet direction of the blowing frame 6. The intercepting net frame 11 is set on the upper side of the rotating plate 8. This arrangement allows the intercepting net frame 11 to intercept and collect the seeds that fall on the discharge plate 4 and are blown by the wind from the blowing frame 6.
[0033] Furthermore, both sides of the frame 1 are provided with arc-shaped holes 12. A positioning rod 10, which is limited by a nut, is movably fitted inside the two arc-shaped holes 12. The positioning rod 10 is movably fitted on the upper side of the rotating plate 8. With this arrangement, the rotating plate 8 can be adjusted by moving the positioning rod 10 within the arc-shaped holes 12, thereby driving the interception net frame 11 on the rotating plate 8 to adjust its angle. This can intercept the seeds that fall and are blown on the discharge plate 4, making it easier to intercept and collect seeds with different falling trajectories and to facilitate the collection and use of different seeds.
[0034] Furthermore, four centrally symmetrical stirring plates 37 are arranged between the two cross-shaped rotating rings 35. This arrangement allows the seeds in the inner adjusting plate 36 to be stirred while rotating and tumbling, thereby improving the reverse selection effect of the outer plate 33 and the inner adjusting plate 36 on the seeds during the rotating state.
[0035] Using the above structure, in use, the fastening nuts on the limiting assembly are loosened, and then the cross rotating ring 35 is rotated to drive the multiple inner adjusting plates 36 to rotate. This adjusts the overlapping area between the multiple inner adjusting plates 36 and the outer plate 33, thereby adjusting the channel between two adjacent outer plates 33 to match the agricultural seeds. Then, the fastening bolts 39 are tightened to align the cross rotating ring with the corresponding pin holes on the pin hole disc 38. Finally, the drive motor 310 and blower 5 are turned on, causing the drive motor 310 to drive the turntable 32, the outer plate 33, and the inner adjusting plates 36 on the cross rotating ring. The seeds to be sorted are poured into the shielding frame through the feed hopper, and the rotating outer plate 33 evenly distributes the seeds. As the seeds enter the outer plate 33, the rotating outer plate 33 and the rotating cross ring screen screen the seeds. The seeds that fall through the outer plate 33 and the inner adjusting plate 36 roll through the discharge plate 4, so that the wind blown by the blower 5 blows the impurities mixed in with the fallen seeds. The seeds are intercepted by the intercepting net frame 11 and fall onto the inclined plate 7. In this way, impurities can be removed from the seeds sorted by the screening mechanism 3.
