Description

Technical Field

[0001] This utility model relates to the technical field of corn screening equipment, and specifically discloses a grading and sorting device for corn processing. Background Technology

[0002] Corn kernels are the seeds of the maize plant, a member of the Poaceae family. They are also part of the fruit and are rich in dietary fiber, vitamins, and minerals, particularly vitamins B, C, and folic acid. These nutrients play an important role in maintaining health and boosting immunity. After separating the kernels from the cob, a sorting device is typically used to sieve the kernels to differentiate and grade them according to their size.

[0003] Chinese patent CN209379372U discloses a sweet corn kernel screening and grading device, including a frame, a screen frame suspended on the frame and inclined to the horizontal plane, and a power source for driving the screen frame to reciprocate. The screen frame is provided with screen plates with adjustable aperture sizes. The screen plates include an upper screen plate and a lower screen plate. The upper and lower screen plates can slide relative to each other along their length direction. Both the upper and lower screen plates have evenly distributed elongated holes. The overlapping portions of the elongated holes on the upper and lower screen plates form screen holes for screening corn. This utility model has a simple structure and is easy to use. When used with an automatic reciprocating power source, it can achieve automatic screening. While automation saves time and effort and improves work efficiency, the aforementioned grading device can only perform single-layer screening of corn kernels. When further grading and screening of corn kernels is required, the position of the upper or lower screen plate needs to be adjusted, and the diameter of the oblong holes needs to be adjusted before a second screening is performed. This affects the quality and efficiency of corn kernel screening to some extent. Furthermore, the design of the inclined slide in the aforementioned grading device makes it inconvenient to adjust the direction of corn kernel discharge, which can easily cause corn kernels to fall from the upper sides of the inclined slide, increasing the workload of the user in picking up corn kernels. Therefore, in order to solve the above problems, this utility model proposes a grading and sorting device for corn processing. Utility Model Content

[0004] The present invention aims to provide a grading and sorting device for corn processing, which can adjust the number of screen plates in the screening mechanism according to the actual sorting requirements, so that the device can simultaneously sort corn kernels of different sizes during operation, improve the efficiency of corn kernel grading and sorting, facilitate the adjustment of the direction of corn kernel discharge, prevent corn kernels from falling off the feeding mechanism, and reduce the workload of users picking up corn kernels.

[0005] This utility model is achieved through the following technical solution:

[0006] A grading and sorting device for corn processing includes a support structure and a reciprocating moving mechanism. The reciprocating moving mechanism is located at one end of the support structure, and a screening mechanism is located inside the support structure. The support structure includes two support plates, which are respectively located on both sides of the screening mechanism. Limit holes are provided inside each of the two support plates. The screening mechanism includes a U-shaped bracket, with sliders connected to both sides of the U-shaped bracket. Two connecting plates are symmetrically connected to the closed end of the U-shaped bracket. Multiple screen plates arranged in a vertical linear array are located inside the U-shaped bracket. A material guiding mechanism is located at the end of each screen plate away from the connecting plates. The material guiding mechanism includes an extension plate, a first baffle, and a second baffle. The first and second baffles are detachably connected to the upper ends of the extension plate, respectively, and a third baffle is detachably connected to the end of the extension plate away from the screen plate.

[0007] As a further feature of the above scheme, two top plates are symmetrically connected to the upper ends of the two support plates, which facilitates the assembly of the support plates and top plates together to form a complete support structure. The slider passes through the interior of the limiting hole and is slidably connected to the limiting hole, which can provide support for the screening mechanism while restricting the movement direction of the screening mechanism. The end of the slider away from the U-shaped bracket is detachably connected to the limiting plate, which can prevent the slider from separating from the limiting hole.

[0008] As a further provision of the above solution, the reciprocating moving mechanism includes a motor and a first connecting shaft. The output end of the motor is connected to the first connecting shaft. The end of the first connecting shaft away from the motor is connected to a turntable. A second connecting shaft is eccentrically arranged on the side of the turntable away from the motor. One end of the second connecting shaft is detachably connected to the turntable. A connecting rod is rotatably connected to the end of the second connecting shaft away from the turntable. A third connecting shaft is rotatably connected to the end of the connecting rod away from the second connecting shaft. Both ends of the third connecting shaft pass through the interior of two connecting plates and are detachably connected to the connecting plates. This facilitates the assembly and maintenance of the above-mentioned components in the reciprocating moving mechanism and provides power for the reciprocating movement of the screening mechanism.

[0009] As a further feature of the above scheme, a base is connected to the outside of the motor, and one end of the base is connected to a support plate to provide support for the motor, the first connecting shaft and other components. A controller is provided on the side of the base away from the support plate to facilitate the control of the motor's operation.

[0010] As a further feature of the above scheme, the inner walls of both sides of the U-shaped bracket are provided with multiple mounting grooves arranged in a linear array. The screen plate is provided with a first protrusion on both sides. The first protrusion is slidably engaged with the mounting groove. The end of the screen plate near the material guiding mechanism is detachably connected to the U-shaped bracket, which facilitates adjusting the number of screen plates according to actual sorting requirements and assembling the screen plates and the U-shaped bracket together. The screen plate is detachably connected to the extension plate, which facilitates the installation and maintenance of the extension plate and the material guiding mechanism.

[0011] As a further feature of the above scheme, the upper two ends of the extension plate are respectively detachably connected to a first guide plate and a second guide plate, and the side of the extension plate away from the screen plate is detachably connected to a third guide plate. This facilitates the disassembly of the above three guide plates and allows for adjustment of the discharge direction of the screened corn kernels according to actual usage needs, thereby improving the flexibility of the guiding mechanism.

[0012] As a further feature of the above solution, a receiving plate is provided on the lower inner side of the U-shaped bracket, and a second protruding plate is provided on both sides of the receiving plate. The second protruding plate is slidably engaged with the mounting groove. The end of the receiving plate near the extension plate is detachably connected to the U-shaped bracket, which can prevent the material screened from the screen plate from falling to the ground and facilitate the centralized discharge of the material.

[0013] The present invention has the following beneficial effects during use:

[0014] The eccentric design of the first and second connecting shafts in the reciprocating motion mechanism helps the motor to drive the turntable and the second connecting shaft to rotate, which in turn pulls the connecting rod, causing the connecting rod to drive the third connecting shaft to move, thereby enabling the slider to slide back and forth in the limiting hole and the screening mechanism to move back and forth.

[0015] The combination of multiple mounting slots and screen plates makes it easy to adjust the number of screen plates according to actual sorting needs and assemble the screen plates with the U-shaped bracket, so that the device can sort corn kernels of different sizes at the same time during operation, reducing the workload of secondary sorting and improving the efficiency of corn kernel sorting.

[0016] The three types of baffles and guide plates in the feeding mechanism are detachably connected to the extension plate, which allows for flexible assembly and disassembly of the three types of baffles and guide plates according to actual usage needs. This enables adjustments to the opening direction in the feeding mechanism and the direction in which corn kernels are discharged from the feeding mechanism, thereby improving the practicality and flexibility of the feeding mechanism.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-8 This application will be described in detail with reference to the embodiments.

[0029] An embodiment discloses a grading and sorting device for corn processing, including a support structure 1 and a reciprocating moving mechanism 2. The reciprocating moving mechanism 2 is located at one end of the support structure 1, and a screening mechanism 3 is located inside the support structure 1. The support structure 1 includes two support plates 11, which are respectively disposed on both sides of the screening mechanism 3. Each of the two support plates 11 has a limit hole 111 inside. The screening mechanism 3 includes a U-shaped bracket 31, and sliders 313 are connected to both sides of the U-shaped bracket 31. Two connecting plates 311 are symmetrically connected to the closed end of the frame 31. Multiple screen plates 32 arranged in a vertical linear array are provided on the inner side of the U-shaped support 31. A material guiding mechanism 33 is provided at the end of the screen plate 32 away from the connecting plate 311. The material guiding mechanism 33 includes an extension plate 331, a first baffle 332 and a second baffle 333. The first baffle 332 and the second baffle 333 are detachably connected to the upper two ends of the extension plate 331, respectively. A third baffle 334 is detachably connected to the end of the extension plate 331 away from the screen plate 32.

[0030] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, two top plates 12 are symmetrically connected to the upper ends of the two support plates 11, which facilitates the assembly of the support plates 11 and the top plates 12 together to form a complete support structure 1. The slider 313 passes through the interior of the limiting hole 111 and is slidably connected to the limiting hole 111, which can provide support for the screening mechanism 3 while restricting the movement direction of the screening mechanism 3. The end of the slider 313 away from the U-shaped bracket 31 is detachably connected to the limiting plate 314, which can prevent the slider 313 from separating from the limiting hole 111.

[0031] like Figure 1 and Figure 3As shown, the reciprocating moving mechanism 2 includes a motor 21 and a first connecting shaft 211. The output end of the motor 21 is connected to the first connecting shaft 211. The end of the first connecting shaft 211 away from the motor 21 is connected to a turntable 23. A second connecting shaft 24 is eccentrically arranged on the side of the turntable 23 away from the motor 21. One end of the second connecting shaft 24 is detachably connected to the turntable 23. A connecting rod 25 is rotatably connected to the end of the second connecting shaft 24 away from the turntable 23. A third connecting shaft 26 is rotatably connected to the end of the connecting rod 25 away from the second connecting shaft 24. The two ends of the third connecting shaft 26 pass through the interior of two connecting plates 311 and are detachably connected to the connecting plates 311, which facilitates the assembly and maintenance of the above-mentioned components in the reciprocating moving mechanism 2 and can provide power for the reciprocating movement of the screening mechanism 3.

[0032] like Figure 1 and Figure 3 As shown, the motor 21 is connected to a base 22 on its outer side. One end of the base 22 is connected to a support plate 11, which can provide support for components such as the motor 21 and the first connecting shaft 211. A controller 4 is provided on the side of the base 22 away from the support plate 11 to facilitate the control of the operation of the motor 21.

[0033] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the inner walls of both sides of the U-shaped bracket 31 are provided with a plurality of mounting grooves 312 arranged in a linear array. The screen plate 32 is provided with a first protruding plate 321 on both sides. The first protruding plate 321 slides in cooperation with the mounting groove 312. The end of the screen plate 32 near the material guiding mechanism 33 is detachably connected to the U-shaped bracket 31, which makes it easy to adjust the number of screen plates 32 according to the actual sorting requirements and assemble the screen plates 32 and the U-shaped bracket 31 together. The screen plate 32 is detachably connected to the extension plate 331, which facilitates the installation and maintenance of the extension plate 331 and the material guiding mechanism 33.

[0034] like Figure 1 and Figure 8 As shown, the upper two ends of the extension plate 331 are respectively detachably connected to the first guide plate 335 and the second guide plate 336, and the side of the extension plate 331 away from the screen plate 32 is detachably connected to the third guide plate 337. This facilitates the disassembly of the above three guide plates and allows for adjustment of the discharge direction of the screened corn kernels according to actual usage needs, thereby improving the flexibility of the guide mechanism 33.

[0035] like Figure 6As shown, a receiving plate 34 is provided on the lower inner side of the U-shaped bracket 31. A second protruding plate 341 is provided on both sides of the receiving plate 34. The second protruding plate 341 is slidably engaged with the mounting groove 312. The end of the receiving plate 34 near the extension plate 331 is detachably connected to the U-shaped bracket 31, which can prevent the material screened from the screen plate 32 from falling to the ground and facilitate the centralized discharge of the material.

[0036] The corn processing grading and sorting device disclosed in this embodiment determines the required number of screen plates 32 based on the number of corn kernels to be graded before use, and selects screen plates 32 with appropriate screen hole sizes. The determined screen plates 32 are then installed from top to bottom inside the U-shaped bracket 31 in descending order of screen hole size. The first protruding plates 321 on both sides of the screen plate 32 are connected to the mounting grooves 312 at the same ground height on both sides of the inner wall of the U-shaped bracket 31. The end of the screen plate 32 away from the connecting plate 311 is installed together with the U-shaped bracket 31. The receiving plate 34 is installed below the bottommost screen plate 32, and the second protruding plates 341 on both sides of the receiving plate 34 slide in the two mounting grooves 312. The end of the receiving plate 34 away from the connecting plate 311 is connected to the U-shaped bracket 31. Multiple guiding mechanisms 33 are sequentially installed on the ends of multiple screen plates 32 away from the connecting plate 311.

[0037] Select the appropriate discharge direction based on the actual discharge requirements and the location of the existing receiving device. When the existing receiving device is located on one side of the U-shaped bracket 31, remove the first baffle 332 and install the first guide plate 335 in the position where the first baffle 332 was removed, or remove the second baffle 333 and install the second guide plate 336 in the position where the second baffle 333 was removed. This allows the corn kernels that have moved from the screen plate 32 to the extension plate 331 to be discharged onto the existing receiving device via the first guide plate 335 or the second guide plate 336. When there are multiple existing receiving devices located on both sides of the U-shaped bracket 31... Remove the first baffle 332 and the second baffle 333 in sequence, and connect the first guide plate 335 and the second guide plate 336 to the extension plate 331 in sequence. When the original receiving device is located at the end of the U-shaped bracket 31 away from the turntable 23, keep the positions of the first baffle 332 and the second baffle 333 unchanged, remove the third baffle 334 from the extension plate 331, and install the third guide plate 337 at the position where the third baffle 334 was removed. After the discharge direction and the position of the receiving device in the guiding mechanism 33 are determined, place a receiving device below the end of the receiving plate 34 away from the turntable 23.

[0038] The controller 4 starts the motor 21, which drives the turntable 23 and the second connecting shaft 24 to rotate via the first connecting shaft 211. The rotation of the second connecting shaft 24 drives the connecting rod 25 to move and pulls the screening mechanism 3 via the third connecting shaft 26, causing the slider 313 to slide back and forth in the limiting hole 111. This causes the screening mechanism 3 to move back and forth, placing the corn kernels to be sorted from above the closed end of the U-shaped support 31 onto the uppermost screen plate 32 for screening. The largest corn kernels remain on the uppermost screen plate 32, while the next largest and smallest corn kernels pass through the sieve holes of the uppermost screen plate 32 and fall down to the next screen plate 32. Smaller corn kernels remain on the next screen plate 32, while even smaller kernels continue to fall onto the next screen plate 32, until the smallest kernels or impurities fall onto the receiving plate 34. Corn kernels of different sizes on each screen plate 32 roll down the direction of the guiding mechanism 33 as the screening mechanism 3 reciprocates, and are discharged onto the corresponding receiving device via the first guide plate 335, the second guide plate 336, or the third guide plate 337 in the discharge direction of the guiding mechanism 33. The material on the receiving plate 34 rolls directly down into the receiving device below the receiving plate 34, thus realizing the grading of corn kernels.

[0039] The reciprocating moving mechanism 2, controller 4, support plate 11, top plate 12, motor 21, first connecting shaft 211, turntable 23, second connecting shaft 24, connecting rod 25, third connecting shaft 26, slider 313, sieve plate 32, extension plate 331, first baffle 332, second baffle 333, third baffle 334, first guide plate 335, second guide plate 336, third guide plate 337, and receiving plate 34 disclosed in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
