Description

Technical Field

[0001] This utility model relates to the field of seed sorting technology, specifically to a vegetable seed sorting device. Background Technology

[0002] The quality of vegetable seeds is a key factor affecting crop yield, quality, and agricultural economic benefits. High-quality seeds should possess characteristics such as high purity, plump grains, and strong vigor. Therefore, precise seed sorting before sowing, removing shriveled, broken, moldy, and impurity seeds, is an indispensable and important step in modern agriculture.

[0003] Currently, the sorting of vegetable seeds mainly relies on the following method: operators manually screen the seeds by visual observation and touch. Although this method is simple, it has fatal drawbacks such as extremely low efficiency, high labor intensity, and inconsistent sorting standards. Working for a long time can easily lead to visual and physical fatigue. The sorting quality and efficiency depend entirely on personal experience, making it difficult to guarantee the consistency of large-scale seed sorting. Moreover, labor costs are increasing day by day.

[0004] There is a significant gap in the existing technology: there is a lack of a vegetable seed sorting device that is simple in structure, low in cost, has higher sorting efficiency and accuracy than traditional mechanical screening, and is easy to promote and apply in small and medium-sized scenarios. Utility Model Content

[0005] To solve the above problems, this utility model provides a vegetable seed sorting device, which is achieved through the following technical solution.

[0006] A vegetable seed sorting device includes a base, a mounting seat fixedly connected to the front end of the base, a frame mounted on the upper end of the base, a frame rotatably connected to the mounting seat at the bottom front side, sliding rods fixedly connected to the front and rear sides of the frame, a screening hopper inside the frame, a first screen fixedly connected inside the screening hopper, sliders fixedly connected to the middle positions of the front and rear sides of the bottom of the screening hopper, toothed plates fixedly connected to the bottom ends of the sliders, springs fixedly connected to the left and right sides of the sliders, and fixed frames fixedly connected to the middle positions of the front and rear sides of the upper end of the frame, with a rolling screening assembly rotatably connected between the fixed frames.

[0007] A lifting assembly, which is disposed between the base and the frame, is used to adjust the tilt angle of the frame;

[0008] A power unit, mounted on the frame, is used to drive the screening bucket to move back and forth and to drive the rolling screening component to rotate.

[0009] As a further embodiment of this utility model, the lifting assembly includes a first fixed seat, a second fixed seat, and a hydraulic cylinder. The first fixed seat is fixedly connected to the middle position of the rear side of the upper end of the base, and the second fixed seat is fixedly connected to the middle position of the rear side of the bottom end of the frame. The hydraulic cylinder is fixedly connected to a first connecting block and a second connecting block at its two ends, respectively. The first connecting block is rotatably connected to the first fixed seat, and the second connecting block is rotatably connected to the second fixed seat.

[0010] As a further embodiment of this utility model, the slider is slidably connected to the corresponding slide rod, and the spring is sleeved and connected to the corresponding slide rod respectively.

[0011] As a further embodiment of this utility model, the rolling screening assembly includes connecting rings located at both ends, a second screen is fixedly connected between the connecting rings, the connecting rings are rotatably connected to corresponding fixed frames, a fixed plate is fixedly connected inside each connecting ring, and a second rotating shaft is fixedly connected between the fixed plates.

[0012] As a further embodiment of this utility model, the power assembly includes a dual-axis motor and a second sprocket. The front end of the output end of the dual-axis motor is fixedly connected to a first rotating shaft through the rear wall of the frame. A lever is fixedly connected to both the front and rear sides of the first rotating shaft. The lever intermittently meshes with the corresponding toothed plates. The rear end of the output end of the dual-axis motor is fixedly connected to a first sprocket. The second sprocket is fixedly connected to the rear end of the second rotating shaft.

[0013] As a further embodiment of this utility model, a protective cover is fixedly connected between the fixing frames, and a brush is fixedly connected to the bottom end of the protective cover.

[0014] As a further embodiment of this utility model, a connecting shaft is fixedly connected to the front side inside the screening hopper, and a baffle is rotatably connected to the connecting shaft. The bottom end of the baffle is bolted to the screening hopper.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By setting up rolling screening components and screening buckets arranged vertically, a two-stage screening process is formed, first coarse and then fine: the second screen (large aperture) first removes extra-large impurities, and the first screen (small aperture) then precisely removes fine impurities and shriveled particles.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0030] Example 1

[0031] A vegetable seed sorting device includes a base 1, a mounting base 2 fixedly connected to the front end of the base 1, a frame 3 provided on the upper end of the base 1, the bottom front side of the frame 3 being rotatably connected to the mounting base 2, sliding rods 21 fixedly connected to the front and rear sides of the inside of the frame 3, a screening hopper 4 provided inside the frame 3, a first screen 5 fixedly connected inside the screening hopper 4, sliders 23 fixedly connected to the middle positions of the front and rear sides of the bottom of the screening hopper 4, toothed plates 24 fixedly connected to the bottom of the sliders 23, springs 25 fixedly connected to the left and right sides of the sliders 23, and fixed frames 7 fixedly connected to the middle positions of the front and rear sides of the upper end of the frame 3, with rolling screening components 9 rotatably connected between the fixed frames 7;

[0032] A connecting shaft 22 is fixedly connected to the front side of the inside of the screening hopper 4. A baffle 6 is rotatably connected to the connecting shaft 22, and the bottom end of the baffle 6 is bolted to the screening hopper 4.

[0033] A lifting assembly is installed between the base 1 and the frame 3 to adjust the tilt angle of the frame 3;

[0034] The power unit is mounted on the frame 3 and is used to drive the screening bucket 4 to move back and forth, and to drive the rolling screening component 9 to rotate.

[0035] In this embodiment, as Figures 1-5 As shown, the overall structure of the vegetable seed sorting device is provided. The base 1 and the mounting base 2 form the basic support. The frame 3 is rotatably connected to the base 1 through the mounting base 2. The cylindrical second screen 27 of the rolling screening component 9 is located above the first screen 5 of the screening hopper 4, and the aperture of the first screen 5 is smaller than the aperture of the second screen 27. The screening hopper 4 is slidably connected to the sliding rod 21 through the slider 23, and can move back and forth in the frame 3. The baffle 6 is rotatably connected through the connecting shaft 22 and fixed by bolts, and is used to control the unloading of the screening hopper 4.

[0036] Example 2

[0037] The difference from Embodiment 1 is that this embodiment discloses a lifting component and a rolling screening component 9:

[0038] The lifting assembly includes a first fixed seat 14, a second fixed seat 17, and a hydraulic cylinder 16. The first fixed seat 14 is fixedly connected to the middle position of the rear side of the upper end of the base 1, and the second fixed seat 17 is fixedly connected to the middle position of the rear side of the bottom end of the frame 3. The hydraulic cylinder 16 has a first connecting block 15 and a second connecting block 18 fixedly connected to its two ends, respectively. The first connecting block 15 is rotatably connected to the first fixed seat 14, and the second connecting block 18 is rotatably connected to the second fixed seat 17.

[0039] The slider 23 is slidably connected to the corresponding slider 21, and the spring 25 is sleeved and connected to the corresponding slider 21 respectively;

[0040] The rolling screening component 9 includes connecting rings 26 at both ends, a second screen 27 fixedly connected between the connecting rings 26, and the connecting rings 26 are rotatably connected to the corresponding fixed frame 7. A fixed plate 28 is fixedly connected inside each connecting ring 26, and a second rotating shaft 29 is fixedly connected between the fixed plates 28.

[0041] In this embodiment, as Figures 1-5 As shown, the lifting component, through the telescopic movement of the hydraulic cylinder 16, pushes the frame 3 to rotate around the mounting base 2, thereby adjusting the tilt angle of the frame 3. This function is not only used to optimize screening efficiency, but more importantly, after screening, the rear of the frame 3 can be lifted to form a state of front low and rear high, which makes it easier for the extra-large impurities remaining in the cylindrical second screen 27 and the fine impurities on the first screen 5 of the screening bucket 4 to fall off by gravity respectively, achieving fast and thorough material discharge and cleaning. The slider 23 is slidably connected to the slide rod 21, and the spring 25 provides the restoring force to ensure that the screening bucket 4 moves stably back and forth under the drive of the power component.

[0042] Example 3

[0043] The power assembly includes a dual-axis motor 10 and a second sprocket 13. The front end of the output end of the dual-axis motor 10 passes through the rear wall of the frame 3 and is fixedly connected to a first rotating shaft 19. The front and rear sides of the first rotating shaft 19 are fixedly connected to levers 20, which intermittently mesh with corresponding toothed plates 24. The rear end of the output end of the dual-axis motor 10 is fixedly connected to a first sprocket 11, and the second sprocket 13 is fixedly connected to the rear end of the second rotating shaft 29. The first sprocket 11 and the second sprocket 13 are driven by a chain 12.

[0044] A protective cover 8 is fixedly connected between the fixed frames 7, and a brush is fixedly connected to the bottom of the protective cover 8.

[0045] In this embodiment, as Figures 1-5As shown, the power assembly synchronously drives the first rotating shaft 19 and the first sprocket 11 through the dual-shaft motor 10. The lever 20 on the first rotating shaft 19 intermittently meshes with the toothed plate 24, pushing the screening bucket 4 to reciprocate left and right. The spring 25 provides the restoring force. The first sprocket 11 drives the second sprocket 13 to rotate through the chain 12, thereby driving the second rotating shaft 29 and the cylindrical second screen 27 to rotate. The protective cover 8 prevents seeds from splashing during the rolling screening, and the brush at its bottom can clean the outer surface of the second screen 27 to prevent the mesh from clogging.

[0046] The working principle of this utility model is as follows:

[0047] Feeding and primary screening (rough selection): The vegetable seeds to be sorted are poured into the cylindrical second screen 27 located above. The dual-shaft motor 10 is started, and its front output shaft drives the first rotating shaft 19 to rotate. The lever 20 rotates accordingly and intermittently meshes with the toothed plate 24, pushing the screening bucket 4 to vibrate back and forth along the slide bar 21 (at this time, the screening bucket mainly plays a supporting role). At the same time, the rear output shaft of the dual-shaft motor 10 drives the first sprocket 11 to rotate, which is transmitted to the second sprocket 13 through the chain 12, driving the second rotating shaft 29 and the cylindrical second screen 27 to rotate at a uniform speed. The seeds tumble continuously in the second screen 27, and extra-large impurities with a size larger than the aperture of the second screen 27 are intercepted, thus achieving preliminary rough selection.

[0048] Secondary screening (selection): Seeds that have passed the primary coarse selection are discharged from the end of the second screen 27 and fall onto the first screen 5 of the screening hopper 4 below. Since the aperture of the first screen 5 is smaller than that of the second screen 27, the screening hopper 4 continuously vibrates back and forth under the drive of the power component. Qualified seeds with a size smaller than the aperture of the first screen 5 pass through the first screen 5 and fall into the collection device (not shown in the figure), while small impurities, shriveled grains, etc. with a size between the apertures of the first screen 5 and the second screen 27 are left on the first screen 5, thus achieving precise secondary screening.

[0049] Feeding and cleaning: After the screening operation is completed, stop the dual-shaft motor 10 and start the hydraulic cylinder 16 to extend it and lift the rear of the frame 3, so that the whole device is in an inclined state with the front lower and the back higher. In this state, the extra-large impurities trapped in the cylindrical second screen 27 will roll down (front end) and concentrate due to gravity, which is convenient for cleaning. At the same time, open the baffle 6 on the front side of the screening hopper 4 so that the fine impurities and shriveled particles left on the first screen 5 can also slide out smoothly. This design greatly facilitates the separate collection of different screen materials (extra-large impurities and fine impurities) and the cleaning and maintenance of the device.

[0050] By adjusting the tilt angle of the frame 3 and the speed of the dual-axis motor 10, the sorting needs of different types and humidity levels of vegetable seeds can be flexibly adapted to achieve efficient and precise sorting operations from coarse to fine.

[0051] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. The selection and detailed description of these embodiments in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
