Description

Technical Field

[0001] This invention relates to the field of agricultural product processing technology, specifically to a tail-end pushing and unloading device for a corn peeling machine. Background Technology

[0002] Fresh corn processing requires harvesting and collection, followed by coarse cutting of the root, coarse cutting of the tip, fine cutting of the root, hulling, blowing out the husk, and peeling before it can enter the food processing stage. Existing vertical corn peeling machines require changing the corn cob from a horizontal to a vertical position after coarse cutting of the root and tip. The track structure for this change is complex. Moreover, the centrifugal force of the rotation affects the subsequent blowing out and peeling processes when the corn cob is upright. Furthermore, a separate power source is required for each rotary blade assembly when cutting the leaves at the root, which increases costs.

[0003] Fresh corn processing requires harvesting and collection, followed by coarse root cutting, coarse tip cutting, fine root cutting, hulling, blowing, and peeling before it can enter the food processing stage. Existing vertical corn peeling machines require changing the corn cob from a horizontal to an vertical position after coarse root and tip cutting, resulting in a complex track structure. Furthermore, the centrifugal force of standing the corn cob upright during blowing and peeling affects subsequent blowing and peeling processes. Additionally, a separate power source is needed for each rotary blade assembly during root leaf cutting, increasing costs. Patent application CN109429738A also discloses a fresh corn peeling machine that uses a tip-pushing device and a tail-pushing device for hulling and blowing. However, during unloading, smaller diameter corn cobs easily pass through the tail-pushing cylinder and are directly carried away by the drill bit, resulting in poor unloading efficiency.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention utilizes a coordinated tip-pushing device and a tail-pushing device, controlled by tip-pushing and tail-pushing tracks, to clamp the corn cob. A long, circular chain conveyor mechanism then drills and fixes the root of the corn cob and cuts the root of the corn leaves, solving the problem of the pre-peeling process, namely root cutting. This invention integrates root cutting into a single clamping process, completing it during the corn peeling machine's transport, resulting in a more compact and simpler structure and higher work efficiency. Compared to traditional peeling machines, this invention peels more thoroughly, achieving a peeling rate of over 95%.

[0021] After the corn has been peeled and hulled, this invention uses a tail sleeve closed track guide sealing gasket to seal the tail sleeve push bowl, and then unloads the material through the drill cutting assembly. Corn cobs of various diameters can be unloaded. Compared with existing corn peeling machines, the unloading effect is better and the working efficiency is higher, with a processing capacity of 12,000-14,000 corn cobs per hour.

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0055] Specific implementation method one: Combining Figures 12-16 To illustrate this embodiment, a tail-end pushing and unloading device for a corn peeling machine is provided, including a tip pushing track 64, a tail pushing track 65, a tail sleeve closed track 66, a circular knife track adjustment mechanism 67, a front cuttings acceleration mechanism 68, a rear peeling acceleration mechanism 69, a long ring chain conveying mechanism 610, and multiple integral trolleys 60.

[0056] The tip pusher rail 64, the tail pusher rail 65, the tail sleeve closed rail 66, the circular cutter rail adjustment mechanism 67, the front cuttings acceleration mechanism 68, the rear peeling acceleration mechanism 69, and the long ring chain conveyor mechanism 610 are all fixed on the frame of the corn peeling machine. Multiple integral trolleys 60 are all fixed on the transmission chain of the long ring chain conveyor mechanism 610. Each integral trolley 60 includes a fixed frame 618, a tip pusher unit 61, and a tail pusher unloading unit 62. The tip pusher unit 61 and the tail pusher unloading unit 62 are arranged correspondingly. The tip pusher unit 61 is guided by the tip pusher rail 64, and the tail pusher unloading unit 62 is guided by the tail pusher rail 65. The front cuttings acceleration mechanism 68 and the rear peeling acceleration mechanism 69 can both drive the circular cutter acceleration sprocket 623 of the tail pusher unloading unit 62 to rotate, causing the drill bit 6214 to rotate.

[0057] Specific Implementation Method Two: Combining Figure 5 and Figure 7 To illustrate this embodiment, the tip pushing unit 61 in this embodiment includes a tip sleeve assembly sliding optical shaft 611, a tip sleeve pushing cylinder 612, a tip sleeve compression spring 613, a tip sleeve fixing seat 614, a tip sleeve fixing seat roller 615, a tip sleeve sliding optical shaft 616, and a tip sleeve spring sliding optical shaft 617.

[0058] The sliding optical axis 611 of the pointed sleeve assembly is connected to the fixed frame 618. The pointed sleeve fixed seat 614 is slidably disposed on the sliding optical axis 611 of the pointed sleeve assembly. The sliding optical axis 616 of the pointed sleeve and the sliding optical axis 617 of the pointed sleeve spring are slidably disposed on the fixed seat 614 of the pointed sleeve. The sliding optical axis 616 of the pointed sleeve and the sliding optical axis 617 of the pointed sleeve spring are parallel to each other.

[0059] The pointed sleeve push cylinder 612 is fixed at the end of the pointed sleeve sliding optical shaft 616 and the pointed sleeve spring sliding optical shaft 617. The pointed sleeve compression spring 613 is set on the pointed sleeve spring sliding optical shaft 617, and the two ends of the pointed sleeve compression spring 613 are respectively pressed against the pointed sleeve push cylinder 612 and the pointed sleeve fixing seat 614. The pointed sleeve fixing seat 614 is provided with a pointed sleeve fixing seat roller 615, and the axis of the pointed sleeve fixing seat roller 615 is perpendicular to the axis of the sliding optical shaft 611.

[0060] The pointed sleeve fixing seat roller 615 is guided by the pointed push rail 64; the pointed sleeve fixing seat roller 615 passes through the fixing frame 618.

[0061] Other components and connections are the same as in Specific Implementation Method 1.

[0062] Specific implementation method three: Combining Figure 4 and Figure 6 To illustrate this embodiment, the tail push unloading unit 62 of this embodiment further includes a drill cuttings assembly sliding optical shaft 621, two push fork sliding optical shafts 622, a drill cuttings assembly roller 625, a drill cuttings housing 626, a round cutter shank 627, a push fork block 629, a push fork roller 6210, a sealing washer 6211, a drill rod 6212, a round cutter 6213, and an insert-type tail sleeve 6215;

[0063] An insert-type tail sleeve 6215 is connected to a fixed frame 618. A tail sleeve push cup 6216 is provided on the insert-type tail sleeve 6215. Friction blocks 63 are provided at both ends of the fixed frame 618. One end of the sliding optical shaft 621 of the drill cuttings assembly is fixed to the insert-type tail sleeve 6215, and the other end is fixed to the friction block 63. The drill cuttings housing 626 is slidably mounted on the sliding optical shaft 621 of the drill cuttings assembly. The sliding optical shaft 622 of the pusher fork is slidably mounted on the drill cuttings housing 626. The sliding optical shaft 621 of the drill cuttings assembly and the sliding optical shaft 622 of the pusher fork are parallel to each other.

[0064] The pusher fork block 629 is fixed on the pusher fork sliding optical shaft 622. The pusher fork block 629 is provided with a pusher fork roller 6210. The axis of the pusher fork roller 6210 is perpendicular to the axis of the pusher fork sliding optical shaft 622. The drill cuttings housing 626 is provided with a drill cuttings assembly roller 625. The axis of the drill cuttings assembly roller 625 is perpendicular to the axis of the drill cuttings assembly sliding optical shaft 621.

[0065] A circular cutter shank 627 passes through a pusher fork block 629. A circular cutter 6213 is provided at the end of the circular cutter shank 627 away from the drill chip housing 626, and a sealing washer 6211 is provided at the end of the circular cutter shank 626. A drill rod 6212 is rotatably connected to the drill chip housing 626. The drill rod 6212 and the sliding optical axis 622 of the pusher fork are parallel to each other. A drill bit 6214 is provided at the end of the drill rod 6212 near the circular cutter 6213. The drill bit 6214 is eccentrically set with the blade on the circular cutter 6213. The drill rod 6212 passes through the circular cutter shank 627 and is located between the two sliding optical axes 622 of the pusher fork. A circular cutter shank screw 628 is installed on the circular cutter shank 627. A drill rod long groove 62121 is provided on the drill rod 6212. The circular cutter shank screw 628 passes radially through the circular cutter shank 627, and the end of the circular cutter shank screw 628 is located inside the drill rod long groove 62121.

[0066] The drill cuttings assembly roller 625 is guided by the tail push rail 65, and the push fork roller 6210 is guided by the tail sleeve closed rail 66; the drill cuttings assembly roller 625 passes through the fixed frame 618.

[0067] In a preferred embodiment, the cylindrical cutter shank 627 passes through the pusher fork block 629, which has a through hole or through groove. The cylindrical cutter shank 627 passes through the through hole or through groove and is clearance-fitted with the through hole or through groove. The cylindrical cutter shank 627 is also machined with two limiting shoulders 6271, which are respectively located on both sides of the pusher fork block 629 to limit movement.

[0068] In a preferred embodiment, the drill rod 6212 is provided with a drill rod long groove 62121, and two round tool holder screws 628 are installed on the round tool holder 627. After the two round tool holder screws 628 are tightened, their ends protrude from the round tool holder 627 and reach the drill rod long groove 62121 on the drill rod 6212, with a 1mm gap between them and the bottom of the drill rod long groove 62121. When the drill rod 6212 rotates, the two round tool holder screws 628 in the drill rod long groove 62121 drive the round tool holder 627 to rotate; the pusher fork block 629 moves back and forth, and drives the round tool holder 627 to move back and forth relative to the drill rod 6212. The two round tool holder screws 628 also play a role in sliding and positioning back and forth in the drill rod long groove 62121.

[0069] In a preferred embodiment, the sealing gasket 6211 is used to prevent corn husks, corn silks and other debris from entering the tail push unloading unit 62 of the present invention during the peeling and blowing processes. At the same time, during unloading, the sealing gasket 6211 seals the round hole in the center of the tail push bowl 6216 to prevent small-diameter corn cobs from being directly carried away by the drill bit 6214 through the tail push bowl 6216, thus preventing ineffective unloading.

[0070] In a preferred embodiment, the drill pipe 6212 is rotatably connected to the drill cuttings housing 626 via two drill pipe bearings 624.

[0071] Each tail push unloading unit 62 is used in conjunction with each tip push unit 61. When the tip sleeve fixing seat roller 615 moves in the negative X-axis direction under the action of external force, the tip sleeve fixing seat 614 drives the tip sleeve push cylinder 612 to move in the negative X-axis direction, and the tip sleeve compression spring 613 continuously applies external force to the tip sleeve push cylinder 612.

[0072] The corn cob conveyed by the corn peeling machine is perpendicular to the X-axis. At this time, the pointed sleeve pusher 612 moves towards the tip of the corn cob and finally pushes against the tip of the corn cob. At the same time, the tail sleeve pusher bowl 6216 pushes against the tail of the corn cob conveyed by the corn peeling machine, and clamps the corn cob by cooperating with the pointed sleeve pusher 612.

[0073] The other components and connections are the same as in Specific Implementation Method 2.

[0074] Specific implementation method four: Combination Figures 12-16 To illustrate this embodiment, the tip pushing track 64 described in this embodiment is composed of a tip in-situ track 640, a first inclined track 641, a first straight track 642, a second inclined track 643, and a second straight track 644 connected together.

[0075] The first inclined track 641, the first straight track 642, and the second inclined track 643 are connected together in a trapezoidal shape. The first inclined track 641 enables the pointed sleeve fixing seat 614 to move in the negative X-axis direction along the axis of the sliding optical axis 611 of the pointed sleeve assembly, and the second inclined track 643 enables the pointed sleeve fixing seat 614 to move in the positive X-axis direction along the axis of the sliding optical axis 611 of the pointed sleeve assembly.

[0076] Combination Figure 14 The pointed sleeve fixing seat roller 615 moves along the slope direction indicated by the arrow on the first inclined section track 641, which enables the pointed sleeve fixing seat 614 to move in the negative X-axis direction along the axis of the sliding optical axis 611 of the pointed sleeve assembly; the pointed sleeve fixing seat roller 615 moves along the slope direction indicated by the arrow on the second inclined section track 643, which enables the pointed sleeve fixing seat 614 to move in the positive X-axis direction along the axis of the sliding optical axis 611 of the pointed sleeve assembly.

[0077] In a preferred embodiment, the acute angle between the first inclined track 641 and the first straight track 642 is smaller than the acute angle between the first straight track 642 and the second inclined track 643.

[0078] The second inclined section of the track 643 is set at such an angle that when the corn cob enters the position of the pointed sleeve push cylinder 612, the compression of the pointed sleeve compression spring 613 is increased, so that the pointed sleeve push cylinder 612 generates a larger pushing force. After the corn cob is drilled, the pointed sleeve push cylinder 612 can detach from the corn cob in a short time, and the corn cob is fixed on the drill bit 6214, which prepares for the subsequent corn cob peeling and blowing.

[0079] Other components and connections are the same as in Specific Implementation Method 3.

[0080] Specific Implementation Method Five: Combining Figures 12-16 To illustrate this embodiment, the tail pusher rail 65 described in this embodiment is composed of a tail in-situ rail 650, a clamping straight rail 651, a circular cutter adjusting straight rail 652, a cutting device positioning straight rail 653, and a discharge inclined rail 654 connected in sequence. The circular cutter adjusting straight rail 652 can be adjusted in position along a direction perpendicular to the length of the tail pusher rail 65. A transition inclined rail 6521 is machined at the connection position between the circular cutter adjusting straight rail 652 and the clamping straight rail 651 to facilitate a smooth transition between the circular cutter adjusting straight rail 652 and the clamping straight rail 651.

[0081] In a preferred embodiment, the unloading inclined track 654 enables the drill cuttings housing 626 to move in the negative X-axis direction along the axis of the sliding optical axis 621 of the drill cuttings assembly.

[0082] Combination Figure 10 This means that the drill cuttings assembly roller 625 moves along the slope direction indicated by the arrow on the unloading inclined section track 654, which enables the drill cuttings housing 626 to move in the negative X-axis direction along the axis of the sliding optical axis 621 of the drill cuttings assembly.

[0083] In a preferred embodiment, the tail in-situ track 650 is correspondingly arranged with the tip in-situ track 640, the clamping straight track 651 is correspondingly arranged with the first inclined track 641 and the first straight track 642 in the first half, the circular cutter adjusting straight track 652 is correspondingly arranged with the second half of the first straight track 642, and the cutting device positioning straight track 653 is correspondingly arranged with the second inclined track 643 and the second straight track 644.

[0084] This setting, combined with Figure 14 and Figure 20 The purpose of setting up the straight section track 652 for adjusting the circular blade is to adjust the front and rear positions of the circular blade 6213 relative to the tail sleeve push bowl 6216. When the circular blade 6213 is closer to the tail sleeve push bowl 6216, the cutting force is greater. When the circular blade 6213 is farther from the tail sleeve push bowl 6216, the cutting force is smaller. This is suitable for peeling corn cobs of different lengths and varieties.

[0085] In a preferred embodiment, the upper half of the long annular chain conveyor 610 has no corresponding track. The tip push track 64 and the tail push track 65 are respectively arranged in the lower half of the long annular chain conveyor 610. The tip in-situ track 640 is connected to the trumpet-shaped tip guide track 645 near the upper left track inlet. The tail in-situ track 650 is connected to the trumpet-shaped tail guide track 655 near the upper left track inlet. The fixed frame 618 has two limiting waist-shaped grooves 6181. The tip sleeve fixing seat roller 615 and the drill cutting assembly roller 625 are both arranged in the limiting waist-shaped grooves 6181. The limiting waist-shaped grooves 6181 limit the maximum and minimum forward and backward movement of the tip sleeve fixing seat roller 615 and the drill cutting assembly roller 625, ensuring that the tip push unit 61 and the tail push unloading unit 62 will not disengage from the track guide when they move to the maximum limit.

[0086] Other components and connections are the same as in Specific Implementation Method Four.

[0087] Specific Implementation Method Six: Combination Figures 12-22To illustrate this embodiment, the tail-end pushing and unloading device further includes two integral trolley lower rails 620 fixed to the corn peeling machine frame. The integral trolley lower rails 620 are positioned below the chain 6103 of the long annular chain conveyor mechanism 610. Friction blocks 63 are provided at both ends of the fixing frame 618 to contact the integral trolley lower rails 620. With this configuration, due to the chain drive structure, the slack side of the chain will sag, affecting the transmission accuracy of the integral trolley 60. Therefore, integral trolley lower rails 620 are respectively provided at both ends of the fixing frame 618, and the friction blocks 63 make frictional contact with the integral trolley lower rails 620.

[0088] The tail sleeve closed track 66 is a straight section track, and the tail sleeve closed track 66 corresponds to the cutting device positioning straight section track 653 and the unloading inclined section track 654.

[0089] This setting, combined with Figure 14 , Figure 21 and Figure 22 Explanation: When the pusher fork roller 6210 enters the tail sleeve closed track 66 along the inclined entry section at the end of the tail sleeve closed track 66, the pusher fork block 629 can drive the round cutter shank 627 to move axially along the drill rod 612. The sealing washer 6211 on the round cutter shank 627 is tightly attached to the side wall of the insert tail sleeve 6215. The sealing washer 6211 can seal the round hole through the corn cob at the center of the tail sleeve push cup 6216.

[0090] During unloading, the sealing gasket 6211 seals the round hole in the center of the tail sleeve push cup 6216 to prevent small-diameter corn cobs from being directly carried away by the drill bit 6214 through the round hole in the center of the tail sleeve push cup 6216, thus preventing effective unloading.

[0091] Other components and connections are the same as in Specific Implementation Method 5.

[0092] Specific implementation method seven: Combination Figures 12-16 To illustrate this embodiment, the circular cutter track adjustment mechanism 67 described in this embodiment is used to adjust the position of the circular cutter adjustment straight section track 652. The circular cutter track adjustment mechanism 67 includes a hand crank 671, a drive long rod 672, a linkage short rod 673, a first drive sprocket 674, a first chain 675, a first driven sprocket 676, two guide sleeves 677, and two support frames 678.

[0093] Two support frames 678 are connected to the frame of the corn peeling machine and are set at both ends of the straight section track 652 for adjusting the circular blade. Two guide sleeves 677 are fixedly connected to both ends of the straight section track 652 for adjusting the circular blade. The drive rod 672 and the linkage rod 673 pass through the guide sleeves 677 and are rotatably connected to the support frame 678. The two guide sleeves 677 are threadedly engaged with the drive rod 672 and the linkage rod 673 respectively. The guide sleeve 677 has a semi-circular raceway inside.

[0094] The first driving sprocket 674 is mounted on the driving rod 672, and the first driven sprocket 676 is mounted on the linkage rod 673. The first driving sprocket 674 and the first driven sprocket 676 are connected and driven by the first chain 675. A hand crank 671 is provided at the end of the driving rod 672 away from the first driving sprocket 674.

[0095] This setting, combined with Figures 9-14 The adjustment circular knife adjustment straight section track 652 is provided with two lifting lugs at both ends. The driving long rod 672 and the linkage short rod 673 pass through the lifting lugs respectively, and nuts are installed on the driving long rod 672 and the linkage short rod 673 to lock the adjustment circular knife adjustment straight section track 652. Each lifting lug is provided with a nut on its side.

[0096] When it is necessary to adjust the relative position of the straight section track 652 of the circular cutter adjustment, loosen the nut and rotate the hand crank 671. The hand crank 671 drives the first driving sprocket 674 and the first driven sprocket 676 to rotate. The guide sleeve 677 drives the straight section track 652 of the circular cutter adjustment to move back and forth, thereby controlling the cutting force of the circular cutter 6213. After adjustment, tighten the nuts on both sides of the straight section track 652 of the circular cutter adjustment.

[0097] The other components and connections are the same as in Specific Implementation Method Six.

The front cuttings acceleration mechanism 68 includes a second chain drive motor 681, a conversion sprocket 682, a conversion chain 683, a second driving sprocket 684, a second chain 685, and a second driven sprocket 686. The conversion sprocket 682 is powered by the second chain drive motor 681.

[0099] The conversion sprocket 682 and the second drive sprocket 684 on the second chain drive motor 681 are connected and driven by the conversion chain 683. The second drive sprocket 684 and the second driven sprocket 686 are connected and driven by the second chain 685. The second chain 685 meshes with the circular knife acceleration sprocket 623.

[0105] Two drive sprockets 6102 are connected together via a drive shaft, which is connected to the frame via a bearing housing. Two driven sprockets 6104 are connected together via a driven shaft, which is connected to the frame via a bearing housing.

[0106] The drive sprocket 6102 is powered by the motor 6101; the mounting brackets 618 of the multiple integral trolleys 60 are all fixed on the two chains 6013.

[0107] Other components and connections are the same as in Specific Implementation Method Nine.

[0108] Working process of this invention:

[0109] The present invention uses an automatic corn placement device to place corn cobs arranged in the same direction into the corn tray 70 of the corn peeling machine. The corn tray 70 is transported to the position of the tail push and unloading device of the present invention by the conveying device on the corn peeling machine. The conveying speed of the long ring chain conveying mechanism 610 of the tail push and unloading device of the present invention is synchronized with the conveying speed of the conveying device on the corn peeling machine.

[0110] like Figure 17 As shown, when the pointed sleeve fixing seat roller 615 on the pointed push unit 61 is guided into the pointed in-situ track 640 through the pointed introduction track 645, at the same time the drill cuttings assembly roller 625 on the tail push unloading unit 62 is guided into the tail in-situ track 650 through the tail introduction track 655, the drill bit 6214 remains detached from the tail sleeve push bowl 6216. At this time, the pointed sleeve push cylinder 612 and the insert tail sleeve 6215 are both far away from the sides of the corn tray 70, and the corn cob is in a clamping state.

[0111] like Figure 18 As shown, when the pointed sleeve fixing seat roller 615 on the pointed push unit 61 enters the first inclined section track 641, the pointed sleeve fixing seat 614 moves in the negative X-axis direction, and the drill cuttings assembly roller 625 on the tail push unloading unit 62 enters the clamping straight section track 651. The position of the drill cuttings housing 626 remains unchanged. At the same time, the pointed sleeve push cylinder 612 clamps the corn cob under the action of the pointed sleeve compression spring 613. The force continuously applied by the pointed sleeve compression spring 613 can clamp corn cobs of different lengths.

[0112] like Figure 19 As shown, the pointed sleeve fixing seat roller 615 on the pointed push unit 61 moves to the end of the first inclined section track 641, the pointed sleeve fixing seat 614 moves to the limit in the negative X-axis direction, the drill cutting housing 626 and the drill bit 6214 remain in their original positions, and the final clamping of the corn cob is completed. While the corn cob is clamped, the precision cutting tail saw blade on the corn peeling machine precisely cuts the root of the corn cob.

[0113] like Figure 20 As shown, when the pointed sleeve fixing seat roller 615 on the pointed push unit 61 enters the first straight section track 642, the position of the pointed sleeve fixing seat 614 remains unchanged. At the same time, the drill cuttings assembly roller 625 on the tail push unloading unit 62 enters the circular cutter adjusting straight section track 652, and the drill cuttings housing 626 moves in the positive X-axis direction. At this time, the drill bit 6214 gradually moves closer to the root of the corn cob. The drill bit 6214 and the circular cutter 6213 rotate under the drive of the front drill cuttings acceleration mechanism 68, and the drill bit 6214 drills into the root of the corn cob.

[0114] like Figure 21 As shown, the pointed sleeve fixing seat roller 615 on the pointed push unit 61 first enters the second inclined section track 643, the pointed sleeve fixing seat 614 moves to the limit in the positive X-axis direction, and then the pointed sleeve fixing seat roller 615 enters the second straight section track 644. After that, the position of the pointed sleeve fixing seat 614 remains unchanged.

[0115] Meanwhile, the cuttings assembly roller 625 on the tail push unloading unit 62 enters the positioning straight section track 653 of the cutting device. The positions of the cuttings housing 626 and the drill bit 6214 remain unchanged. The push fork roller 6210 enters the tail sleeve closed track 66, driving the round cutter handle 627 to move closer to the insertion tail sleeve 6215. The tail sleeve closed track 66 guides the sealing gasket 6211 on the round cutter handle 627 to seal the central round hole of the tail sleeve push cup 6216. At the same time, the round cutter handle 627 pushes the corn cob away from the insertion tail sleeve 6215 but still remains on the drill bit 6214. At this time, the drill bit 6214 rotates under the drive of the rear peeling acceleration mechanism 69. The air blowing device of the corn peeling machine performs peeling processes such as hulling and blowing on the rotating corn cob.

[0116] like Figure 22 As shown, the tip sleeve fixing seat roller 615 of the tip push unit 61 disengages from the tip push track 64, the tip sleeve fixing seat 614 is ready to enter the tip original position track 640 for guidance, the push fork roller 6210 is held in the tail sleeve closed track 66, and the tail sleeve closed track 66 continues to guide the sealing gasket 6211 on the round knife handle 627 to seal the tail sleeve push bowl 6216.

[0117] At the same time, the drill cuttings assembly roller 625 on the tail push unloading unit 62 enters the unloading inclined section track 654, and the drill cuttings housing 626 moves in the negative X-axis direction. At this time, the drill bit 6214 moves away from the corn cob and exits from the root of the corn. The insert tail sleeve 6215 separates the corn cob from the drill bit 6214, causing the corn cob to fall into the recycling device of the corn peeling machine. The drill cuttings housing 626 is ready to be recycled into the tail original track 650 for guidance, and so on in a reciprocating cycle.

[0118] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
