Description

Technical Field

[0001] The invention relates to a method, process and flow for sorting and identifying large and small ends of corn cobs. Background Art

[0002] Existing corn cobs need to be cored and the seeds taken out, either by manual peeling or by hard friction with a friction roller to separate the seeds from the cob core, which will damage the outer wall of the seed. Since corn cobs are different, with different lengths and shapes, it brings great disadvantages to automation. How to automatically identify the large and small ends of the corn cobs has become a technical problem that needs to be solved urgently.

[0003] In addition, corn cob sorting is an important pre-process for the applicant in automatically obtaining corn seeds. Since corn cobs generally have a conical structure, the existing process still has errors in sorting corn cobs. This is because different corn cobs have different seed saturation and varieties. When the appearance is used for sorting, there are errors. How to achieve clever automated identification of large and small heads has become a technical problem that urgently needs to be solved.

[0004] In addition, corn cobs need to be sorted after being harvested. The methods used are nothing more than manual sorting, or first removing the outer coating and cutting directly without identifying the two ends, which causes a large amount of corn kernels to be wasted and causes the seeds to be damaged by bumps during operation.

[0005] Sorting corn cobs has always been a technical challenge in this field. Therefore, cameras are generally used for identification, which is extremely costly and requires algorithm optimization and pre-stored large numbers of seed models.

[0006] How to improve the sorting effect and realize the automatic identification of the top and root of corn cobs has become a technical problem that needs to be solved urgently. Summary of the invention

[0007] In response to the above technical problems, Shandong Denghai Seed Co., Ltd. has carried out a series of cooperative research and development with Jilin University, Jilin Academy of Agricultural Sciences and other universities. As the creative part, the technical problem to be solved by the present invention is generally to provide a method for sorting the large and small ends of corn cobs and a corn cob adjustment and transmission device.

[0008] To solve the above problems, the technical solution adopted by the present invention is:

[0009] In order to realize the automatic transmission of corn cobs, a method for identifying the large and small ends of corn cobs is provided. The method is by adjusting the transmission device. The method includes the following steps: (the following steps can be used alone or in combination)

[0010] Step A, conveying the transversely placed corn cobs to the sorting section one by one; the transverse arrangement can be pre-placed or adjusted by a robot.

[0011] Step B: In the sorting section, the first sorting section sorts the corn cobs by gripping the ear part of the corn and adjusts the large and small end directions to be unified, and / or the second sorting section sorts the corn cobs by utilizing the difference between the center of gravity and the central position and adjusts the large and small end directions to be unified;

[0012] And / or Step C: The output section receives the upright corn cobs falling from the sorting section and outputs them to the next process.

[0013] To achieve the sorting of corn cobs, they can be used alone or in combination.

[0014] To achieve sorting by utilizing the characteristics of the corn cob, a sorting process for the large and small ends of the corn cob is carried out. Step B is executed to sort the corn cobs.

[0015] When the corn cob has an ear part, Step B1 is executed. The first sorting section sorts the corn cob by gripping the ear part of the corn and adjusts the large and small end directions to be unified.

[0016] To achieve sorting by utilizing the corn ear, the sorting process in Step B1 includes the following. First, the horizontal corn cobs are sent to the orientation adjustment station through the horizontal conveyor belt group. In the orientation adjustment components A and B, the corresponding corn ears are bitten. With the assistance of the blowing component, the corn ears are fed into the ear rolling component at the ear rolling station. Through the rubber rollers, the elastic unevenness shortens the biting distance, so as to better achieve the twisting of the corn ears, which can not only remove the corn ears but also utilize the corn ears to identify the direction.

[0017] When the corn ear is dry or when the corn cob does not have an ear part, Step B2 is executed. The second sorting section sorts the corn cob by utilizing the difference between the center of gravity and the central position and adjusts the large and small end directions to be unified.

[0018] As a further improvement of the above technical solution:

[0019] At the ear - removing station, the pair - twisting roller part of the ear rolling component rotates in the reverse direction to spit out or continue to roll in and disconnect the ear part of the corn, so that the corn cobs fall one by one through the transition guide sleeve to the flipping station. Secondly, at the flipping station, the corn cobs fall through the inclined guide plate, so that the large end of the corn cob enters the reversing device part. The reversing device part swings downward due to the loading of the corn cob, so that the corn cobs enter the vertical - falling guide sleeve through the V - shaped structure channel formed by the downward - inclined guiding piece and the protection plate part and fall for output.

[0020] To achieve sorting by utilizing the center of gravity and the center of the corn, a sorting process for the large and small ends of the corn cob with an ear part

[0021] A sorting process for the large and small ends of corn cobs based on the center of gravity and the center. The sorting process step B2 includes the following content. First, the corn cobs fall into the falling frame and lie flat in the inclined mating baffle by their own weight. The inclined mating baffle is oscillated by the spring drive rod to adjust the position of the corn cobs. Then, the V-shaped centering gripper is driven to grip both ends of the corn cob for centering, so that the length center of the corn cob is directly above the protrusion of the middle roller. Secondly, the inclined mating baffle is opened by the spring drive rod, so that the middle part of the falling corn cob contacts the protrusion of the middle roller. Under the action of its own weight, the large end of the corn cob sinks and falls along the guiding inclined plate into the receiving station in the first falling channel or the second falling channel, falls into the swinging bracket from the upper opening and swings down to the falling station. Thirdly, the corn cob with the large end facing up slides away, realizing the unified vertical output of the large and small ends of the corn cob. After that, at the falling station, the corn cob falls to the sliding-out station through the lower side guard plate. At the sliding-out station, the corn cob falls into the conical support sleeve of the second vertical conveyor belt.

[0022] The general idea of the present invention is to utilize the center of gravity of the corn cob to separate the large and small heads of the corn cob and realize unified direction sorting, thereby overcoming the problems of complex algorithms for existing pattern recognition, poor generality of shape recognition, and low efficiency. The specific technical problems and beneficial effects are described in detail in combination with the specific embodiments.

[0023] The present invention realizes the fixed-direction grasping of the corn cob by using the corn ear, so as to turn away from the conveyor belt along with the rotation, realizing the vertical downward output of the corn cobs one by one. The present invention uses the corn ear to grip the corn cob and through the cooperation of the center and the center of gravity, sorts the corn cobs that cannot be gripped by the corn ear. The present invention provides work efficiency through combined sorting. It realizes automatic direction change and automatic vertical fixed-direction output one by one.

[0024] The present invention is reasonably designed, low in cost, strong and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and convenient to use. Brief Description of the Drawings

DETAILED DESCRIPTION

[0038] like Figures 1-12 As shown, the corn cob adjustment and transmission device of this embodiment includes a sorting part for picking corn cob bodies 4 so that the corn cob bodies 4 are in a uniform direction, thereby facilitating later adjustment so that the corn cobs are in a uniform vertical direction. The input end of the sorting part is connected to the input part, thereby realizing the input of corn cobs, especially horizontal input one by one.

[0039] The output end of the sorting section is connected to the output section, so that the sorted corn cobs can be output vertically one by one. The input section includes a feeding input belt 27, which may have a horizontal bar, a blower, a manipulator or other components; a connection adjustment section is connected behind the feeding input belt 27, which is a preferred structure, so that the corn cobs can be positioned and adjusted one by one horizontally and output. A sorting section is arranged behind the adjustment section; an output section is arranged below the sorting section; in order to make later processing more convenient. The feeding input belt 27 transports the corn cob body 4 forward;

[0040] The connection adjustment part includes an inclined feeding belt 28 arranged to tilt upward, which is used to place the corn cob body 4 horizontally for transmission; its inclination is preferably greater than 45 degrees, so as to achieve better adjustment of the corn cob.

[0041] A transverse conveyor belt group 7 is provided at the output end of the inclined feeding belt 28; the transverse conveyor belt group 7 has an L-shaped bracket 36 for carrying the transversely placed corn cobs 4; it is similar to a hook structure and realizes automatic positioning of the corn cobs.

[0042] The output part is used to receive the corn cobs 4 dropped from the sorting part and send them to the next process.

[0043] As a preferred structure, the corn cob 4 includes a corn cob 5; a corn seed 6 is distributed on the corn cob 4. An eight-shaped retaining edge 33 with a middle gap 34 is distributed on the inclined feeding belt 28 for carrying the two ends of the horizontal corn cob 4. The middle gap 34 is used to drop the vertical corn cob 4 back to the lower input end. When the falling corn cob 4 hits the corn cob 4 at the input end, it changes direction or uses a manipulator to place the longitudinal corn cob 4 in a horizontal position. Of course, a side baffle or two conveyor belts can form a V, and a vibration part is set at the connection to achieve vibration drive adjustment; a limited height frame 35 is set at the input end of the inclined feeding belt 28. The limited height frame 35 is used to block the stacked corn cobs 4 from moving forward and rolling them back to the input end; of course, other too high limits can also be used.

[0044] The L-shaped bracket 36 includes a front short side 37 and a rear long side 38, so as to facilitate the rear to enter and receive, and at the same time, facilitate the front corner to achieve rapid separation.

[0045] At the input end of the inclined feeding belt 28, components such as a manipulator and / or a camera, and a guard plate are provided; at the output end of the inclined feeding belt 28, a guiding plate is provided, which can be an arc-shaped plate, so as to guide the corn cob to better fall to the rear long side 38 and roll to the large L-shaped bracket 36.

[0046] The sorting section includes a first sorting section that clamps the corn ear 3 and / or a second sorting section that utilizes the difference between the center of gravity and the central position; through two different sorting methods, the separation of different corn cobs is realized, and the problem that the corn ear will be wound around the central rod and affected is solved. Through the combination of the two, the disadvantage is turned into an advantage.

[0047] The output section includes a first vertical conveyor belt 29 arranged below the first sorting section and a second vertical conveyor belt 32 arranged below the second sorting section; the two can be used alone or in combination.

[0048] As an application case, such as Figures 5-10 , the first sorting section drops the corn cob body 4 with the large end facing down; a flipping station 64 is arranged below the first sorting section; an inclined guiding plate 65 located below the first sorting section is inclinedly arranged at the flipping station 64; an adjusting device section 66 is arranged at the lower outlet of the inclined guiding plate 65, a downward inclined guiding member 67 is arranged at the output station below the adjusting device section 66, a guard plate section 68 is arranged on the opposite side of the downward inclined guiding member 67, and the downward inclined guiding member 67 and the guard plate section 68 form a V-shaped structure channel; a vertically falling guiding sleeve 69 is arranged below the downward inclined guiding member 67; the adjusting device has the same structure, so it can be directly applied and is briefly described. In short, a downward inclined falling force is generated to make the adjusting section fall, resulting in sinking, so that the corn cob falls through the V-shaped guide.

[0049] The output section, the first vertical conveyor belt 29 carries the corn cob body 4 with the small end facing down that falls through the vertically falling guiding sleeve 69; the second vertical conveyor belt 32 carries the corn cob body 4 with the small end facing down that falls from the second sorting section. Thus, unified output is realized.

[0050] The first vertical conveyor belt 29 and the second vertical conveyor belt 32 have the same structure, and the drive shaft of the first vertical conveyor belt 29 is erected; conical support sleeves 39 are vertically distributed on the first vertical conveyor belt 29; elastic openings 40 are opened on the side walls of the conical support sleeves 39. Thus, positioning is realized. The inner hole diameter of the large end of the conical support sleeve 39 is between the large end diameter and the small end diameter of the corn cob body 4; thus, further sorting is realized. Through different diameters, the discharge with the large head facing down is realized, and the small head facing down enters and uses the downward impact force to make it open to realize holding and clamping.

[0051] As a specific introduction, the first sorting section includes alignment components A10 and alignment components B11 which are symmetric and have the same structure, and are arranged on both sides of the alignment station 9 at the output end of the horizontal conveyor belt group 7; thereby realizing clamping at both ends and realizing twisting and picking of the corn cobs on both sides of the corn cob heads.

[0052] The alignment components A10 and / or the alignment components B11 include a rotating frame body part 13; a selection support seat is arranged at the lower part of the rotating frame body part 13, which can be of a conventional structure; a central connecting shaft 14 is arranged at the top of the rotating frame body part 13 for connecting power to drive the rotation of the rotating frame body part 13; it can be driven to rotate by gear transmission, hydraulic pressure or a motor.

[0053] At least three groups of ear winding components 15 are distributed in the rotating frame body part 13, and the ear winding components 15 respectively correspond to an inspection station 17, a de - earring station 18 or an ear winding station 19; thereby realizing the completion of corresponding work, and redundant stations can be set.

[0054] The ear winding station 19 is located at the side end of the alignment station 9; thereby realizing roller - twisting clamping of the corn cobs. Thereby realizing twisting and curling of the corn cobs, picking up the corn cobs without damaging the corn cobs, while reducing the previous ear - picking process, and cleverly using the ear - picking to solve the direction and position problems.

[0055] Preferably, the linear velocity of the axial center of the twisting roller part 16 of the rotating frame body part 13 is greater than or equal to the forward speed of the horizontal conveyor belt group 7; thereby realizing synchronous or rapid forward movement of the corn cobs.

[0056] As a specific introduction, there can be redundant stations. The ear winding components 15 include symmetrically arranged twisting roller parts 16; thereby realizing twisting and grasping of the corn cobs.

[0057] At the inspection station 17, a camera and a cutter controlled by a manipulator are arranged, which are used to detect that the corn cob part 3 wound around the twisting roller part 16 exceeds a set threshold value, and the cutter is used to cut off the corn cob part 3 wound on the twisting roller part 16; it can be realized through image recognition, thereby realizing cleaning and realizing cleaning and detection of the corn cobs.

[0058] At the ear winding station 19, the twisting roller parts 16 contact each other in opposite directions to twist the corn cob part 3 and carry the corn cob to the de - earring station 18; thereby realizing twisting and clamping of the corn cob and driving it to move forward and leave the L - shaped support seat. At the de - earring station 18, the twisting roller parts 16 continue to twist in opposite directions to twist off the corn cob part 3, causing the corn cob to fall, and at the same time realizing separation of the fluff. The twisting roller parts 16 can rotate in the reverse or forward direction at this station, and thus spitting out or biting off the corn cob is within the scope of protection.

[0059] At the middle of the orientation station 9 at the output end of the horizontal conveyor belt group 7, the input end of the middle variable-direction vibration channel 8 is connected; at one side of the bottom of the output end of the middle variable-direction vibration channel 8, a variable-direction stop lever 30 is provided; it realizes the orientation of the advancing corn cobs, and of course, it can also realize the advancement of conveyor belts in two perpendicular directions. On the inner side wall of the middle variable-direction vibration channel 8, side elastic pieces 70 are provided; thus, elastic collisions are generated for the advancing corn cobs, so that they can better become vertical states and avoid jamming.

[0060] Preferably limited for corn cobs, the sorting component has a handle 2 for the corn cob body; the handle 2 is wrapped with corn husk 1; at the top of the handle 2, there is a corn ear 3, and the clamping is realized by clamping the corn ear. Of course, the corn ear should be kept moist and flexible, rather than dry and brittle.

[0061] At the center of the rotating frame part 13, a central brush 20 is provided for cleaning the pair-rolling roller part 16, so as to avoid scratching the pair-rolling roller part 16 and at the same time realize the cleaning of the corn ear.

[0062] On the rotating frame part 13, an air nozzle part 21 is provided, which can blow air on the corn ear.

[0063] Between adjacent ear-rolling components 15, a partition plate 22 is provided to realize isolation from each other and avoid interference.

[0064] On the rotating frame part 13, a spacer plate 23 is provided to isolate the lower ear-rolling components 15, so as to protect the core components.

[0065] Below the ear-rolling station 19, a blowing component 24 is inclinedly arranged; the blowing component 24 blows obliquely upward on the drooping corn ear 3; thus, it is convenient to feed the corn ear to be bitten.

[0066] At the lower part of the rotating frame part 13, an inclined support plate 71 is provided between the ear-rolling station 19 and the ear-removing station 18 for realizing the lower support of the rotating and moving corn cobs;

[0067] Outside the ear-removing station 18, a side guard plate 70 is inclinedly arranged, so as to realize the separation of the corn cob and the corn ear 3.

[0068] The pair-rolling roller part 16 includes a rubber roller 25 elastically arranged, which can be an inflatable airbag and is connected with a pressure pipeline, so as to judge the deformation amount of the rubber airbag according to the pressure change, and thus derive the twisting and biting of the corn cob; on the outer side wall of the rubber roller 25, elastic protrusions and depressions 26 are distributed, thus realizing better twisting of the corn ear of the corn cob, and even the end of part of the husk. At the same time, through the elastic arrangement, the biting space becomes smaller, so as to better bite the corn ear.

[0069] The two pairs of pair-rolling roller parts 16 of the ear-rolling component 15 rotate in opposite directions through gear meshing; thus, opposite or same-direction rotation is realized.

[0070] The angle α between the axis connecting line BC of the two pairs of twisting rollers 16 of the ear winding assembly 15 and the conveying direction ED of the transverse conveyor belt group 7 is an acute angle, so as to facilitate the feeding of the corn cob end into the corn cob better.

[0071] like Figure 11 , Figure 12 The second sorting part includes a falling frame 41 with an opening at the middle bottom, so as to realize lying and carrying the corn cobs, and realize the concentrated falling and gathering of the corn cobs.

[0072] The opening of the falling frame 41 is hinged with an inclined matching baffle 43; when the inclined matching baffle 43 is matched, a V-shaped structure channel is formed, thereby realizing automatic positioning and opening and closing. It can realize the self-positioning of corn cobs during opening and closing, and at the same time, it prevents debris from accumulating in the frame and can realize output one by one.

[0073] An intermediate roller 44 with a convex top is horizontally arranged in the middle below the inclined matching baffle 43; the different positions of the midpoint and the center of gravity are used to achieve ingenious automatic classification. The intermediate roller can be circular, triangular prism or other shapes. The intermediate roller can be a triangular prism to achieve support for the center. According to experience, the center of the corn cob body and the center of gravity are relatively large, so the center position adjustment error of the present invention can be met, and it can also be adjusted according to different positions.

[0074] A first drop channel 45 and a second drop channel 46 are respectively arranged on the left and right sides of the middle roller 44, so as to realize the output of corn cobs and separate output, and cleverly utilize the cross-shaped structure.

[0075] An adjusting device 47 is provided at the obliquely lower exit of the first falling channel 45 and the second falling channel 46 to realize automatic separation; it is a component using the same structural principle as the above-mentioned adjusting component, and if a slightly different structure is adopted, it is understandable and is equivalent.

[0076] A transversely movable V-shaped centering gripper 42 is provided above the falling frame 41. The V-shaped centering gripper 42 is used to longitudinally move the falling corn cob so that the center of the corn cob is aligned with the middle roller 44, thereby facilitating the alignment of the fall.

[0077] A guide inclined plate 48 is provided at the first falling channel 45 and the second falling channel 46 respectively, for guiding the corn cobs falling obliquely to the corresponding adjusting device 47;

[0078] The adjustment device 47 includes a fixedly arranged articulated bracket 49 to achieve fixed support; a swing bracket 50 is hingedly connected to the articulated bracket 49, and its pitch structure is utilized to achieve automatic adjustment and unified output;

[0079] Specifically, a receiving station 51 is provided at the lower outlet of the guiding inclined plate 48; a falling station 52 is provided below the receiving station 51;

[0081] When loaded, the inlet and outlet of the swing bracket 50 swing downward to face the falling station 52; the center of gravity of the corn cob and the center of gravity of the swing bracket 50 are located on the side of the hinge bracket 49 close to the receiving station 51;

[0082] The swing bracket 50 has an upper opening 57 for receiving the falling corn cobs, so as to facilitate better receiving of the corn cobs;

[0083] An auxiliary ejecting rod 58 driven by a push rod is provided at the bottom of the swing bracket 50 to assist in ejecting the corn cobs;

[0084] An elastic limiting block 59 is provided on the hinge bracket 49 for contacting the swing bracket 50, which can be a spring or rubber, etc., to reduce noise and generate vibration at the same time, so that the corn cobs can fall better;

[0085] A return spring 60 is provided between the hinge bracket 49 and the swing bracket 50 to play a buffering role;

[0086] A spring drive rod 63 is connected between the falling frame 41 and the inclined mating baffle 43. When the corn cobs fall, the baffle is slightly opened and closed through the spring part, so as to facilitate the inclined corn cobs to lie flat better. It can be composed of a section of rod plus a section of spring;

[0087] When in use, the premise is that the center of gravity of the corn cob is close to the large end of the root relative to the center of the corn cob;

[0088] The present invention realizes a clever output and falling;

[0089] As an improvement, an elastic guide plate 56 is provided on the inner side wall of the guiding inclined plate 48 for lateral positioning of the falling corn cobs; thus facilitating correct falling onto the swing bracket 50. Of course, a V-shaped channel or a supporting funnel can also be used. However, through inclination, two component velocities, one downward and one horizontal, are given to the corn cobs, so that the corn cobs fall obliquely onto the swing bracket 50;

[0090] First, the corn cob falls into the falling frame 41, and lies flat in the inclined matching baffle 43 by its own weight, and the inclined matching baffle 43 is oscillated by the spring driving rod 63 to adjust the position of the corn cob; then, the V-shaped centering gripper 42 is driven to clamp the two ends of the corn cob for centering, so that the length center of the corn cob is located directly above the protrusion of the middle roller 44; secondly, the inclined matching baffle 43 is opened by the spring driving rod 63, so that the middle part of the falling corn cob contacts the protrusion of the middle roller 44, and under the action of its own weight, the large end of the corn cob sinks and falls to the receiving station 51 along the guide inclined plate 48 in the first falling channel 45 or the second falling channel 46, and falls into the swing bracket 50 from the upper opening 57 and swings down to the falling station 52; thirdly, the large end of the corn cob slides upward and leaves, so that the large and small ends of the corn cob are uniformly output upright;

[0097] Step B, in the sorting section, the first sorting section sorts the corn cobs 4 by gripping the ear part 3 of the corn and adjusts the large and small end directions to be unified, and / or the second sorting section sorts the corn cobs 4 by utilizing the difference between the center of gravity and the central position and adjusts the large and small end directions to be unified;

[0098] And / or Step C, the output section receives the upright corn cobs 4 falling from the sorting section and outputs them to the next process.

[0099] As a safeguard, in Step A, the horizontal corn cobs 4 move forward on the feeding input belt 27; the corn cobs 4 are sent onto the inclined feeding belt 28, and due to the slope of the inclined feeding belt 28 and the middle gap 34, the longitudinal and / or stacked corn cobs 4 fall to the input end. The horizontal corn cobs 4 are lifted by the eight-shaped edge 33 and move forward to the output end, and the stacked corn cobs 4 are blocked from moving forward by the height limit frame 35 and roll back to the input end; the horizontal corn cobs 4 are output forward to the horizontal conveyor belt group 7 and are lifted by the L-shaped support 36 and move forward to the sorting section;

[0100] When the falling corn cobs 4 touch the corn cobs 4 at the input end, they change direction, or the longitudinal corn cobs 4 are placed horizontally by the manipulator.

[0101] In Step C, when the large end of the falling corn cob 4 descends and touches the conical support sleeve 39, it is blocked from entering; when the small end descends and touches the conical support sleeve 39, it enters, and due to the downward impact force, the conical support sleeve 39 uses the elastic opening 40 to open and clamp the corn cob 4.

[0102] As a safeguard, for the sorting process of the large and small ends of the corn cobs in this embodiment, Step B is executed to sort the corn cobs 4;

[0103] When the corn cob 4 has the ear part 3, Step B1 is executed. The first sorting section sorts the corn cob 4 by gripping the ear part 3 of the corn and adjusts the large and small end directions to be unified;

[0104] When the corn cob 4 does not have the ear part 3, Step B2 is executed. The second sorting section sorts the corn cob 4 by utilizing the difference between the center of gravity and the central position and adjusts the large and small end directions to be unified.

[0105] As a safeguard, for the sorting process of the large and small ends of the corn cob with the ear part 3 in this embodiment, the sorting process Step B1 includes the following content. First, the horizontal corn cob is sent to the orientation station 9 through the horizontal conveyor belt group 7. In the orientation assembly A 10 and the orientation assembly B 11, the corresponding ears of corn are bitten. With the assistance of the blowing of the blowing assembly 24, the ears of corn are fed into the ear rolling assembly 15 at the ear rolling station 19; through the rubber roller 25 and the elastic unevenness 26, the biting distance is shortened, thereby better realizing the twisting of the ears of corn.

[0106] At the ear - removing station 18, the counter - twisting roller part 16 of the ear - rolling assembly 15 rotates in the reverse direction to spit out or continue to roll in the corn ear part 3 and disconnect it, so that the corn cob 4 falls one by one through the transition guide sleeve 12 to the flipping station 64; Secondly, at the flipping station 64, the corn cob 4 falls through the inclined guide plate 65, so that the large end of the corn cob 4 enters the reversing device part 66. The reversing device part 66 swings downward due to the loading of the corn cob 4, so that the corn cob 4 enters the vertical falling guide sleeve 69 and falls out in the V - shaped structure channel formed by the downward - inclined guide part 67 and the protective plate part 68.

[0107] As a protection, in the process of sorting the large and small ends of the corn cob 4 based on the center of gravity and the center in this embodiment, the sorting process step B2 includes the following content. First, the corn cob 4 falls into the falling frame 41 and lies flat in the inclined mating baffle 43 by its own weight. The inclined mating baffle 43 is oscillated by the spring - driven rod 63 to adjust the position of the corn cob 4; Then, the V - shaped centering gripper 42 is driven to grip both ends of the corn cob 4 for centering, so that the length center of the corn cob 4 is directly above the protrusion of the middle roller 44; Secondly, the inclined mating baffle 43 is opened by the spring - driven rod 63, so that the middle part of the falling corn cob 4 contacts the protrusion of the middle roller 44. Under the action of its own weight, the large end of the corn cob 4 sinks and falls along the guiding inclined plate 48 in the first falling channel 45 or the second falling channel 46 to the receiving station 51, falls into the swinging bracket 50 from the upper opening part 57 and swings downward to the falling station 52; Again, the large - end - upward sliding of the corn cob 4 is made to leave, so that the large and small ends of the corn cob 4 are uniformly erected and output in the same direction; After that, at the falling station 52, the corn cob 4 falls through the lower side guard plate 55 to the sliding - out station 53. At the sliding - out station 53, the corn cob 4 falls into the conical support sleeve 39 of the second vertical conveyor belt 32.

[0108] As an extended protection, the secondary corn cob sorting system of this embodiment includes a transverse conveyor belt group 7; A corn cob sorting assembly is arranged at the output end of the transverse conveyor belt group 7, and the corn cob sorting assembly is used to circularly and forwardly convey the horizontally arranged corn cobs; Transition guide sleeves 12 are respectively arranged below the ear - removing station 18 of the alignment assembly A10 and the ear - removing station 18 of the alignment assembly B11.

[0109] The corn cobs are horizontally arranged on the transverse conveyor belt group 7, thus realizing the feeding of the corn cobs one by one. As the working process, first, the horizontal corn cobs are sent to the alignment station 9 by the transverse conveyor belt group 7. In the alignment assembly A10 and the alignment assembly B11, the corresponding corn ears are bitten. With the assistance of the blowing of the blowing assembly 24, the corn ears are fed into the ear - rolling assembly 15 at the ear - rolling station 19; Through the rubber roller 25 and the elastic concavity - convexity 26, the biting distance is shortened, so as to better realize the twisting of the corn ears. The rotating frame part 13 rotates to the ear - removing station 18.

[0110] At the de-earing station 18, the twisting roller part 16 of the ear winding assembly 15 rotates in the opposite direction to disconnect the corn cobs from being spit out or continued to be wound in, so that the corn cobs fall to the transition guide sleeve 12 to be arranged vertically one by one. The inclined support plate 61 supports the corn cobs and is used to lift the rotating corn cobs downward to prevent them from falling in the middle. It can be provided with an inclined groove to realize the automatic falling of the corn cobs. The side guard plate 62 separates the corn cobs from the corn cob part 3, so that the corn cobs fall better. During this period, inspection and trimming are realized through the inspection station 17, the center brush 20 realizes cleaning, the air nozzle part 21 realizes cleaning, and the isolation plate 22 and the spacer plate 23 avoid interference.

[0111] The present invention realizes transmission through the feeding input belt 27 and the inclined loading belt 28. The present invention hides and omits components such as bearings, bolts, and part of the frame. The first vertical transmission belt 29 realizes output. The change-direction lever 30 realizes change of direction after the corn cobs are touched. The second vertical conveyor belt 32 has the same structure. The eight-shaped retaining edge 33 and the middle gap 34 realize the output of the corn cobs. The height limit frame 35 realizes blocking the corn cobs from being output one by one. The L-shaped bracket 36 facilitates the input and rapid output of the corn cobs through the front short side 37 and the rear long side 38. The conical support sleeve 39 realizes automatic identification of clamping and size heads through the elastic opening 40. The slide-out station 53 and the flip station 64 are virtual stations. The front side guard plate 54 and the lower side guard plate 55 realize change-direction guidance and generate the required vector speed. The oblique guide plate 65 and the adjustment device part 66 have the same principle as the adjustment device and are not repeated here. The downward oblique guide member 67, the protective plate part 68, and the vertical falling guide sleeve 69 realize auxiliary change of direction.
