Description

Technical Field

[0001] This invention relates to the field of corn threshing technology, and more specifically to a quick-frozen corn threshing mechanism. Background Technology

[0002] Corn is one of the most commonly consumed crops in the world. To extend its shelf life and preserve its original flavor, corn is typically quick-frozen. This process makes whole-kernel corn easier to transport and store, and it extends shelf life without the need for preservatives. Current quick-frozen corn comes in two common forms: first, whole-kernel quick-frozen corn, which is frozen whole and then packaged for transport and storage; and second, the kernels are removed from the surface of the quick-frozen corn, packaged, and then used individually.

[0003] In the existing technology, there are many technical equipment for threshing corn, including various threshing mechanisms such as using a ring cutter disc, rubber roller threshing, and centrifugal swing bar impact. Each has its own advantages and disadvantages. When using a ring cutter disc threshing mechanism, the frozen corn is moved laterally on the conveyor equipment, and the frozen corn is brought into the inner arc surface of the ring cutter disc. Then, the frozen corn is evenly contacted with multiple threshing blades in the ring cutter disc, and the corn kernels on the surface of the frozen corn are completely separated.

[0004] In the process of threshing large quantities of quick-frozen corn, there are significant volume differences among the various quick-frozen corns. This requires the selection of corresponding ring cutter sizes. When there are certain differences in the size of the quick-frozen corn, frequently adjusting the size and installation angle of the multiple threshing cutters in the corresponding ring cutter head will waste a lot of quick-frozen corn threshing time. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide a quick-frozen corn threshing mechanism, which solves the technical problem in the related art that it is difficult to ensure efficient threshing of a large batch of quick-frozen corn of different volumes during use.

[0006] At least one embodiment of the present invention provides a quick-frozen corn threshing mechanism, including a layered conveying structure with multiple conveying end faces, conveying quick-frozen corn, corn cobs, and corn kernels from top to bottom respectively. A quick-frozen corn feeder is provided on one side of the layered conveying structure, and multiple threshing frames are arranged around the layered conveying structure. The mechanism also includes: Each of the threshing frames is provided with a conveying channel. A rotating and flipping structure is provided between the conveying channel and the threshing frame. A belt conveyor assembly, an extrusion conveyor assembly, and a pushing conveyor assembly are provided in the conveying channel to drive the quick-frozen corn to move laterally in the conveying channel. The cutter head clamping frame is provided on the threshing machine frame. An adjustable cutter head structure is provided inside the cutter head clamping frame. Multiple threshing cutters are rotatably arranged on the adjustable cutter head structure. A corn sorting rack with a feeding function is provided on one side of the quick-frozen corn feeder and the layered conveying structure. The corn sorting rack is provided with multiple sorting channels to sort the quick-frozen corn that moves onto the layered conveying structure by volume. The corn sorting rack has multiple area restriction components on its bottom side to restrict the movement area of ​​quick-frozen corn of different volumes.

[0007] According to one embodiment of this application, the rotating and flipping structure includes a rotating ring plate, an arc-shaped support member, and a meshing transmission assembly. The rotating ring plate is fixedly sleeved in the middle of the conveying channel. The arc-shaped support member is provided on the threshing frame and is slidably connected to the rotating ring plate. The meshing transmission assembly is provided between the rotating ring plate and the threshing frame, driving the rotating ring plate and the conveying channel to flip.

[0008] According to one embodiment of this application, the extrusion conveying assembly includes a mounting shaft and a drive shaft. Multiple mounting shafts are rotatably connected to the upper and lower ends of the conveying channel near the cutter head clamping frame. A friction sleeve is fixedly fitted on each mounting shaft. Multiple drive shafts are rotatably connected between the mounting shaft and the cutter head clamping frame. A conveying sleeve is fitted on each drive shaft. Multiple meshing blades are arranged circumferentially on the conveying sleeve.

[0009] According to one embodiment of this application, the material conveying assembly includes a transverse trough and an offset push plate. The transverse trough is disposed in the conveying channel. An offset rotating shaft is disposed on the transverse trough. The offset push plate is rotatably sleeved on the offset rotating shaft. A first drive cylinder is disposed on the transverse trough to drive the offset push plate to flip. A push groove is disposed on the bottom side of the offset push plate near the mounting rotating shaft.

[0010] According to one embodiment of this application, a shaft drive device is provided on the threshing frame, and the upper side of the shaft drive device has multiple connecting shafts. The belt conveyor assembly has multiple transmission shafts, and the multiple connecting shafts are respectively connected to the mounting shaft, the drive shaft, or the transmission shaft.

[0011] According to one embodiment of this application, the adjustable cutter head structure includes an annular disc seat, a mounting shaft seat, and an annular internal tooth groove. Multiple meshing slots are arranged around the inner circumference of the cutter head clamp frame. The annular disc seat is disposed between multiple meshing slots via multiple meshing inserts. Multiple mounting shaft seats are rotatably disposed on the annular disc seat, and these mounting shaft seats are circumferentially distributed on the annular disc seat. The threshing cutter is disposed on corresponding mounting shaft seats. The annular internal tooth groove is rotatably connected to one side of the annular disc seat. Each mounting shaft seat is provided with a transmission gear, and the multiple transmission gears mesh with the annular internal tooth groove.

[0012] According to one embodiment of this application, the threshing tool has two threshing forks, and a plurality of threshing end faces are formed between the two threshing forks.

[0013] According to one embodiment of this application, a semi-circular through groove is provided on the upper side of the cutter head clamp frame, and a push rod is slidably connected in the semi-circular through groove. The push rod is connected to the annular inner tooth groove.

[0014] According to one embodiment of this application, a mounting frame is fixedly connected to the corn sorting trough. The mounting frame is located between the corn sorting trough and the quick-frozen corn feeding machine. A drive spindle and several connecting spindles are provided inside the mounting frame. Each drive spindle and several connecting spindles is provided with a material feeding plate, so that the quick-frozen corn enters the corn sorting trough and is aligned with the direction of the sorting channels. The inner diameter of the multiple sorting channels distributed from the side closest to the mounting frame to the other side increases progressively.

[0015] According to one embodiment of this application, the area restriction component includes a vertical support plate and a bending restriction strip. The vertical support plate is fixedly connected to the corn sorting trough frame, and the bending restriction strip is rotatably provided on one side of the vertical support plate. The bending restriction strip bends to form a corn movement area.

[0016] This invention provides a quick-frozen corn threshing mechanism. Compared with existing technologies, it uses a corn sorting trough to sort quick-frozen corn falling onto a layered conveying structure according to volume. Under the action of multiple area-limiting components, multiple quick-frozen corns with similar volumes move within the same corn movement area. Each corn movement area corresponds to several threshing frames. The rotation angle of the threshing blades within the cutter head clamps on the corresponding threshing frames is adjusted to accommodate different corn outer diameters. This allows the corn kernels to be threshed after passing through multiple threshing blades during lateral conveying. Furthermore, by sorting multiple corn kernels, the position of the threshing blades within different cutter head clamps corresponds to the volume of the corn, avoiding excessive adjustments to the threshing blades during the threshing process. This effectively improves corn threshing efficiency and makes the machine more convenient to use. Attached Figure Description

The embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] Please refer to the following embodiment of the quick-freezing corn threshing mechanism. Figure 1The system includes a layered conveyor structure 1 with multiple conveying end faces, conveying frozen corn, corn cobs, and corn kernels from top to bottom. The layered conveyor structure 1 includes multiple conveying troughs, each with a conveyor belt system. These multiple conveyor belts give the layered conveyor structure 1 multiple conveying end faces, allowing it to convey not only unthreshed frozen corn but also threshed corn cobs and kernels on different conveyor belts. A frozen corn feeder 2 is located on one side of the layered conveyor structure 1, and multiple threshing frames 3 are arranged around it. The frozen corn feeder 2 conveys the frozen corn to the uppermost conveyor belt, allowing the frozen corn to be conveyed within the range of the multiple threshing frames 3.

[0027] Also includes conveyor channel 4, please refer to Figure 4 Each threshing frame 3 is equipped with a conveying channel 4, and a rotating and flipping structure is provided between the conveying channel 4 and the threshing frame 3. Even when corn is sorted, there are still differences in volume between similar corn kernels, making it difficult to adjust the threshing blades 7 to meet all corn threshing needs. During the process of corn passing between multiple threshing blades 7, some corn kernels may still remain on the surface of the corn after threshing. In order to ensure the threshing effect of the corn, the rotating and flipping structure is rotated when the corn is conveyed laterally in the conveying channel 4, so that the corn can slowly rotate and contact the multiple threshing blades 7, ensuring that the corn kernels on the surface of the corn are cleanly threshed. Corn with a volume corresponding to the multiple threshing blades 7 does not need to be conveyed by rotating the conveying channel 4.

[0028] The rotating and flipping structure includes a rotating ring plate 101, an arc-shaped support member 102, and a meshing transmission assembly. Please refer to [link / reference]. Figure 2 and Figure 3A rotating ring plate 101 is fixedly sleeved in the middle of the conveying channel 4. An arc-shaped support 102 is provided on the threshing frame 3, which is slidably connected to the rotating ring plate 101. A meshing transmission assembly is provided between the rotating ring plate 101 and the threshing frame 3 to drive the rotating ring plate 101 and the conveying channel 4 to rotate. The meshing transmission assembly includes a motor drive device. Meshing gears 111 are sleeved on the output ends of the rotating ring plate 101 and the motor drive device. The two meshing gears 111 mesh with each other. When it is necessary to rotate the conveying channel 4, the motor drive device is started. Through the transmission effect of the two meshing gears 111, the rotating ring plate 101 is driven to rotate on the arc-shaped support 102, which drives the conveying channel 4 to rotate within a small range. When the conveying channel 4 is rotated, the conveying channel 4 moves within a small range, which makes the corn fully contact the multiple threshing blades 7. During the use of this invention, the control of rotating the conveying channel 4 comes from the on-site operator's judgment based on the volume of the corn to be threshed, to determine whether the corn needs to be rotated and conveyed for threshing.

[0029] Conveying channel 4 is equipped with belt conveyor assembly 5, extrusion conveyor assembly, and pusher conveyor assembly. Please refer to [link / reference]. Figure 3 The conveyor drives the quick-frozen corn to move laterally within the conveyor channel 4. A semi-circular cylindrical cover is hinged to the conveyor channel 4 to enclose the belt conveyor assembly 5. In actual use, the operator stands on one side of the layered conveyor structure 1 and takes corn from the layered conveyor structure 1 to fill the conveyor channel 4. To improve the protection of the operator and the inner structure of the conveyor channel 4, the semi-circular cylindrical cover is pressed against the upper side of the conveyor channel 4 during use. The belt conveyor assembly 5 is a commonly used object conveying structure in the prior art. By driving the drive shaft 403 to rotate, the belt conveyor assembly 5 is driven to convey the corn towards the cutter head clamp frame 6.

[0030] The extrusion conveyor assembly includes a mounting shaft 201 and a drive shaft 203. (See attached image.) Figure 4 Multiple mounting shafts 201 are rotatably connected to the upper and lower ends of the conveying channel 4 near the cutter head clamping frame 6. Each mounting shaft 201 is fixedly fitted with a friction bushing 202. Multiple driving shafts 203 are rotatably connected between the mounting shaft 201 and the cutter head clamping frame 6. Each driving shaft 203 is fitted with a conveying bushing 204. Multiple meshing blades are arranged on the circumference of the conveying bushing 204. When corn moves towards the cutter head clamping frame 6 through the belt conveyor assembly 5, the corn will first enter between the multiple friction bushings 202 on the upper and lower sides. By driving the mounting shaft 201 to rotate, the corn moves into the cutter head clamping frame 6. Then the corn comes into contact with the conveying bushing 204, and the meshing blades abut against the corn. When the driving shaft 203 rotates, it drives the corn into the cutter head clamping frame 6.

[0031] When moving the corn from the belt conveyor assembly 5 into the multiple friction bushings 202, please refer to Figure 4 To ensure that the corn enters between the multiple friction bushings 202, the present invention also provides a pushing and conveying assembly, which includes a transverse trough frame 301 and an offset pushing plate 303. The transverse trough frame 301 is disposed in the conveying channel 4, and an offset rotating shaft 302 is disposed on the transverse trough frame 301. The offset pushing plate 303 is rotatably sleeved on the offset rotating shaft 302. A first drive cylinder 304 is disposed on the transverse trough frame 301 to drive the offset pushing plate 303 to rotate. A pushing recess is provided on the bottom side of the offset pushing plate 303 near the mounting shaft 201. The first drive cylinder 304 is mounted on the transverse slot frame 301 via a pin seat. The output end of the first drive cylinder 304 is rotatably connected to the offset push plate 303. When the first drive cylinder 304 is started, it pushes the offset push plate 303 to rotate along the center point of the offset shaft 302, and makes the push groove 305 at the bottom of the offset push plate 303 correspond to the tail of the corn, ensuring that the midpoint of the movement of the tail of the corn corresponds to the position of the friction bushing 202. Then, the offset push plate 303 is used to drive the corn to move between multiple friction bushings 202.

[0032] The threshing frame 3 is equipped with a shaft drive device 401. Please refer to [link / reference]. Figure 2 and Figure 5 The shaft drive device 401 has multiple connecting shafts 402 on its upper side, and the belt conveyor assembly 5 has multiple drive shafts 403. The multiple connecting shafts 402 are respectively connected to the mounting shaft 201, the drive shaft 203 or the drive shaft 403. The shaft drive device 401 is a prior art device with a shaft drive assembly, which is a prior art device known to those skilled in the art. The shaft drive device 401 has multiple rotatable connecting shafts 402, which are connected to the mounting shaft 201, the drive shaft 203 or the drive shaft 403. When the shaft drive device 401 drives the multiple connecting shafts 402 to rotate, it drives the mounting shaft 201, the drive shaft 203 and the drive shaft 403.

[0033] Because the conveying channel 4 needs to be slightly rotated later, in order not to affect the transmission connection between the connecting shaft 402 and the mounting shaft 201, the drive shaft 203 and the transmission shaft 403, a shaft seat 411 is provided on the connecting shaft 402. A universal joint 412 is provided between the shaft seat 411 and the mounting shaft 201, the drive shaft 203 or the transmission shaft 403, so that the mounting shaft 201, the drive shaft 203 and the transmission shaft 403 can rotate slightly with the conveying channel 4. When the connecting shaft 402 is parallel to the mounting shaft 201, the drive shaft 203 or the transmission shaft 403, the connecting shaft 402 can drive the mounting shaft 201, the drive shaft 203 and the transmission shaft 403 to rotate.

[0034] The threshing frame 3 is equipped with a cutter head clamp 6, please refer to [link / reference]. Figures 6 to 8 The cutter head clamping frame 6 is composed of two semi-circular clamping frames hinged together. An adjustable cutter head structure is provided inside the cutter head clamping frame 6. Multiple threshing cutters 7 are rotatably arranged on the adjustable cutter head structure. The adjustable cutter head structure includes an annular disc seat 501, a mounting shaft seat 504, and an annular internal tooth groove 505. Multiple meshing slots 502 are provided on the inner circumference of the cutter head clamping frame 6. The annular disc seat 501 is arranged between multiple meshing slots 502 through multiple meshing inserts 503. The annular disc seat 501 is first connected to the upper semi-circular clamping frame through the meshing inserts 503. Then, when the two semi-circular clamping frames are aligned to form a complete circle, the annular disc seat 501 is connected to the lower semi-circular clamping frame through the meshing inserts 503 and the meshing slots 502.

[0035] Multiple mounting seats 504 are rotatably mounted on the annular disc base 501. The mounting seats 504 are circumferentially distributed on the annular disc base 501. The threshing blades 7 are mounted on the corresponding mounting seats 504. An annular internal toothed groove 505 is rotatably connected to one side of the annular disc base 501. Each mounting seat 504 is equipped with a transmission gear 506. The multiple transmission gears 506 mesh with the annular internal toothed groove 505. When it is necessary to adjust the flipping position of the multiple threshing blades 7 according to the corn volume, the annular internal toothed groove 505 is driven to rotate on the annular disc base 501. Through the meshing relationship between the annular internal toothed groove 505 and the transmission gear 506, the multiple mounting seats 504 and the multiple threshing blades 7 are driven to rotate synchronously, so that the corresponding threshing end face on the threshing blade 7 corresponds to the corn volume.

[0036] The threshing blade 7 has two threshing forks 507, and multiple threshing end faces are formed between the two threshing forks 507. When the position of the threshing blade 7 is adjusted according to the volume of the corn, the corresponding multiple threshing end faces are made to contact the corn kernels on the outside of the corn. When the corn volume difference is greater, two threshing forks 507 of different sizes are used to thresh the corn separately.

[0037] A semi-circular through groove 508 is provided on the upper side of the cutter head clamp frame 6. A push rod 509 is slidably connected in the semi-circular through groove 508. The push rod 509 is connected to the annular inner tooth groove 505. By pushing the push rod 509 to move in the semi-circular through groove 508, the annular inner tooth groove 505 rotates on one side of the annular disc seat 501. Furthermore, the push rod 509 and the semi-circular through groove 508 also have damping braking properties, which can effectively prevent the annular inner tooth groove 505 from rotating and resetting.

[0038] The bottom of the cutter head clamping frame 6 is connected to a discharge channel 801, which corresponds to the lowermost conveying end face of the layered conveying structure 1. The side of the annular disc seat 501 away from the annular inner tooth groove 505 is sloped to facilitate the threshed corn kernels entering the discharge channel 801 and then onto the corresponding conveyor belt surface on the layered conveying structure 1. Additionally, a cob discharge channel 802 is also provided on the side of the cutter head clamping frame 6 away from the conveying channel 4 to transport the threshed corn cobs to the corresponding conveyor belt surface, completing the separate conveying of corn kernels and corn cobs.

[0039] The present invention also includes a corn sorting trough 8 with a feeding function; please refer to [link to relevant documentation]. Figure 1 and Figure 9 The corn sorting trough 8 is located on one side of the quick-frozen corn feeder 2 and the layered conveyor structure 1. Multiple sorting channels 9 are provided inside the corn sorting trough 8 to sort the quick-frozen corn moving onto the layered conveyor structure 1 by volume. A mounting frame 601 is fixedly connected to the corn sorting trough 8, located between the corn sorting trough 8 and the quick-frozen corn feeder 2. The mounting frame 601 contains a drive shaft 602 and several connecting shafts 603. Each drive shaft 602 and connecting shaft 603 is equipped with a material-pulling plate 604 to facilitate the sorting of the quick-frozen corn. The corn enters the corn sorting rack 8, which is aligned with the sorting channel 9. The inner diameter of the multiple sorting channels 9, which are distributed from the side closest to the mounting rack 601 to the other side, increases progressively. When the quick-frozen corn moves from the quick-frozen corn feeder 2 to the uppermost conveyor belt of the layered conveyor structure 1, the corn will pass through the top of the mounting rack 601 and enter the corn sorting rack 8. The corn rolls down in the corn sorting rack 8 and, according to its own volume, passes through multiple sorting channels 9 from small to large, finally entering the conveyor belt through a sorting channel 9 that matches its own volume.

[0040] Because when the quick-frozen corn feeder 2 moves the corn, it is difficult to ensure that multiple corns are conveyed at an angle parallel to the sorting trough 9. However, when the corn passes through the mounting frame 601, multiple material-pulling rods are used to move the corn, so that the corn is conveyed at an angle parallel to the sorting trough 9.

[0041] The corn sorting rack 8 is equipped with another motor drive device that drives the main drive shaft 602 to rotate. The main drive shaft 602 and each connecting main shaft 603 are equipped with synchronous pulleys 605. The number of synchronous pulleys 605 on the main drive shaft 602 is equal to the number on the connecting main shaft 603. The synchronous pulleys 605 on the main drive shaft 602 and the connecting main shaft 603 are connected by a synchronous belt 606. When the motor drive device corresponding to the main drive shaft 602 drives the main drive shaft 602 to rotate, the numerous synchronous pulleys 605 and the synchronous belt 606 drive the multiple connecting main shafts 603 to move accordingly. Since the initial position of each feeding plate 604 is not fixed, the multiple feeding plates 604 can cooperate with each other to achieve uninterrupted sorting of multiple corn kernels.

[0042] The bottom side of the corn sorting rack 8 is equipped with multiple area restriction components; please refer to [link / reference]. Figure 1 and Figure 9 This device is used to restrict the movement area of ​​quick-frozen corn of different volumes. The area restriction component includes a vertical support plate 701 and a bending restriction belt 702. The vertical support plate 701 is fixedly connected to the corn sorting trough 8. The bending restriction belt 702 is rotatably set on one side of the vertical support plate 701. The bending restriction belt 702 bends to form the corn movement area. According to the movement area of ​​the sorted corn, when the sorted corn is moved to the range of several corresponding threshing frames 3, the bending restriction belt 702 is driven to bend, guiding the corn movement position. Two adjacent bending restriction belts 702 can cooperate with each other to guide the corn to move in the corresponding area. The bending restriction belt 702 is provided with a metal wire structure, which can prevent the bending restriction belt 702 from deforming after bending. A connecting clip 703 is provided on one side of the bending restriction belt 702. The connecting clip 703 can be used to close the loop of the bending restriction belt 702 or to keep it connected to the vertical support plate 701.

[0043] During operation, the quick-frozen corn threshing mechanism first moves the corn onto the layered conveyor structure 1 via the quick-frozen corn feeder 2. As the corn is removed from the quick-frozen corn feeder 2, it falls into the corn sorting trough 8 via the mounting trough 601. Then, by rotating multiple material guide plates 604, the corn position is adjusted to keep it parallel to the sorting trough 9. After being sorted by the sorting trough 9, the corn falls onto the uppermost conveyor belt of the layered conveyor structure 1, and then moves to the corresponding threshing frame 3 area.

[0044] The operator picks up corn and fills it into the conveyor channel 4. First, the belt conveyor assembly 5 drives the corn to move towards multiple mounting shafts 201. The first drive cylinder 304 is activated to push the offset push plate 303 to assist the corn in entering between multiple friction bushings 202 on the upper and lower sides. By driving the mounting shafts 201 to rotate, the corn moves into the cutter head clamp 6. Then, the corn comes into contact with the conveyor bushings 204, and the meshing blades abut against the corn. When the drive shaft 203 rotates, it drives the corn into the cutter head clamp 6.

[0045] The positions of multiple threshing blades 7 within the cutter head clamp 6 are pre-adjusted.
