DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-13 As shown, a fully automatic corn planter includes a shaft cover 1 and a rotating disc 2 assembled on the shaft cover 1, including: The duckbill clamps 3 are arranged in a circular array on the turntable 2, and include a movable clamp 31 movable relative to a fixed clamp 32; A scraper 35 is mounted on the inner wall of the duckbill clamp 3 and moves radially with the movement of the movable clamp 31. The scraper 35 in radial movement is slidably connected to the inner wall of the fixed clamp 32 / movable clamp 31; The slag inlet chamber 7 is arranged at the tail end of the duckbill clamp 3, which is connected through the input end of the suction pump, and the suction pump is combined with the duckbill clamp 3 to form a passage; It also includes a leveling shovel 4 for leveling the ground, which engages with multiple dynamic clamps 31 one by one when the turntable 2 rotates.

[0021] Specifically, the shaft cover 1 is fixedly arranged on a hand-pushed seeding vehicle or other seeding machines, and a seed wheel 11 for seeding is arranged inside the shaft cover 1, and a seeding tube pointing to the turntable 2 is provided on the seed wheel 11. Corn seeds pass through the seed wheel 11 and enter the feeding cavity 22 provided on the turntable 2 one by one, and under the action of gravity, they roll into the duckbill clamp 3 in the closed state through the opening provided on the fixed clamp 32. The structures involved in the above technology are all well-known technical common sense to those skilled in the art, and will not be described in detail here.

[0022] Furthermore, a first end of a first spring 34 is provided on the movable jaw 31, and a second end is fixedly connected to the turntable 2. The movable jaw 31 is rotatably arranged relative to the fixed jaw 32. The first spring 34 enables the movable jaw 31 to remain in close contact with the fixed jaw 32 through an elastic force, thereby keeping the duckbill clamp 3 in a closed state, with the end of the duckbill clamp 3 located in the turntable 2 as the tail end, and the end opposite thereto as the head end.

[0023] A gear may be provided on the movable jaw 31, and a rack meshing with the gear may be provided on the scraper 35. When the movable jaw 31 is opened, the gear is driven to rotate relative to the rack, thereby driving the rack to extend radially out of the duckbill clamp 3, so that the scraper 35 slides out of the inner cavity of the duckbill clamp 3; when the movable jaw 31 is closed, the rotation direction of the gear changes and drives the rack and the scraper 35 to retract into the duckbill clamp 3. Alternatively, a guide slot may be provided on the movable jaw 31, and a transmission rod slidably matched with the guide slot may be provided on the scraper 35. When the movable jaw 31 is opened, the transmission rod is guided to extend through the guide slot, thereby driving the scraper 35 to slide out of the duckbill clamp 3; when the movable jaw 31 is closed close to the fixed jaw 32, the guide slot guides the transmission rod to retract, driving the scraper 35 to retract into the duckbill clamp 3, or other driving methods known to those skilled in the art may be used.

[0024] Furthermore, the leveling shovel 4 is arranged on the shaft cover 1 and is located in front of the moving path of the turntable 2. When the sowing vehicle or other sowing machine is used to move the sowing, the leveling shovel 4 is driven to level the uneven soil piles on the front path, thereby avoiding the bumps during the rotation of the turntable 2. When the turntable 2 drives the duckbill clamp 3 to rotate close to the block 432, the block 432 will block the movable clamp 31, so that the movable clamp 31 overcomes the elastic force of the first spring 34 and rotates relative to the fixed clamp 32, the duckbill clamp 3 opens, and the rotating movable clamp 31 blocks the entrance of the slag inlet chamber 7, so that the slag inlet chamber 7 stops suction, avoiding continuous suction of corn grains. At this time, the scraper 35 slides radially and extends to the outside of the duckbill clamp 3, pushing the corn grains inside the duckbill clamp 3 into the soil below, and clearing the wet mud inside the duckbill clamp 3.

[0025] After the turntable 2 drives the duckbill clamp 3 to continue to rotate at a certain angle, the movable jaw clamp 31 and the block 432 are offset, and the block 432 no longer blocks the movable jaw clamp 31. The movable jaw clamp 31 is pulled by the elastic force of the first spring 34 and recovers to be close to the fixed jaw clamp 32, so that the duckbill clamp 3 is closed. At the same time, the scraper 35 retracts to the inside of the duckbill clamp 3, and the scraper 35 scrapes the inner wall of the duckbill clamp 3 to prevent the wet mud from adhering to the duckbill clamp 3. When the duckbill clamp 3 is closed, the movable jaw clamp 31 is offset from the entrance of the slag inlet chamber 7, so that the slag inlet chamber 7 is connected with the inner cavity of the duckbill clamp 3, and the wet mud scraped off the scraper 35 is sucked into the slag chamber 7, and the airflow of the suction accelerates the drying of the wet mud, and promotes the speed of the wet mud agglomeration and falling. After the corn kernels enter the duckbill clamp 3, the corn kernels can be adsorbed by the suction of the slag inlet chamber 7, so that the corn kernels stay in the duckbill clamp 3 near the tail end, thereby preventing the corn kernels from being stuck to the inner wall of the duckbill clamp 3 by the wet mud in the duckbill clamp 3.

[0026] In the above technology, the scraper 35 slides radially and extends to the outside of the duckbill clamp 3 when the duckbill clamp 3 is opened, pushing the corn seeds inside the duckbill clamp 3 into the soil below to avoid clogging of the corn seeds, and clearing the wet mud inside the duckbill clamp 3. When the duckbill clamp 3 is closed, the scraper 35 retracts toward the inside of the duckbill clamp 3. The scraper 35 scrapes the inner wall of the duckbill clamp 3 to avoid wet mud adhering to the duckbill clamp 3, thereby improving the sowing effect.

[0027] As an embodiment further provided by the present invention, it also includes a slide bar 33 slidably arranged on the turntable 2 in a radial direction, and a scraper 35 is rotatably arranged at a first end of the slide bar 33 and is kept in a horizontal state by a first torsion spring 333; The scraper 35 is tilted by the relative sliding of the slide bar 33 and the duckbill clamp 3 .

[0028] Specifically, the scrapers 35 are arranged opposite to each other and hinged to the first end of the slide bar 33, and the scrapers 35 are provided with a first torsion spring 333 to keep the two scrapers 35 in a horizontal state. The movable jaw 31 may be provided with a gear and the slide bar 33 may be provided with a rack meshing with the gear; or the slide bar 33 may be fixedly connected to the output end of the electric telescopic rod so that the slide bar 33 is driven to slide radially during the movement of the movable jaw 31, or other driving methods known to those skilled in the art may be used.

[0029] Furthermore, during the sliding process of the slide bar 33 toward the outer periphery of the turntable 2, the scraper 35 abuts against the inner walls of the movable clamp 31 and the fixed clamp 32, and the direction of the friction force of the movable clamp 31 and the fixed clamp 32 on the scraper 35 is opposite to the moving direction of the slide bar 33. At this time, the scraper 35 tilts, and the first torsion spring 333 begins to deform and store energy, and an acute angle pointing to the outer periphery of the turntable 2 is formed between the two scraper blades 35, which divides and dredges the wet mud in the duckbill clamp 3 through this acute angle. When the scraper 35 detaches from the duckbill clamp 3, the potential energy of the first torsion spring 333 is released and drives the scraper 35 to return to a horizontal state, and the corn kernels are pressed into the soil through the shaking of the first torsion spring 333 when the elasticity is released.

[0030] When the slide bar 33 slides toward the center of the turntable 2, the scraper 35 tilts again, and the tilting direction is opposite to the previous tilting direction, so that the two scraper blades 35 form an angle pointing to the center of the circle. The two scraper blades 35 squeeze the soil during the tilting process, and the squeezing direction is toward the central axis of the two scraper blades 35, so that the soil accumulates toward the center line, thereby preliminarily covering the corn grains, fixing the position of the grains, and improving the planting accuracy.

[0031] When the scraper 35 moves radially from the periphery to the tail end of the duckbill clamp 3, it is no longer pressed by the movable clamp 31 / fixed clamp 32, so that the scraper 35 returns to a horizontal state, and the wet mud scraped during the process remains on the scraper 35 and is then sucked into the slag chamber 7.

[0032] As an embodiment further provided by the present invention, the scraper 35 is symmetrically provided with a cone head 36 which is pushed by the edge of the movable clamp 31 and moves relatively.

[0033] Specifically, the cone head 36 is slidably arranged on the scraper 35, and an elastic member 38 is arranged between the two cone heads 36, so that the cone head 36 has a driving force to extend outward from the scraper 35. When the duckbill clamp 3 is closed, the inner wall of the movable jaw 31 abuts against both sides of the scraper 35, and the movable jaw 31 blocks the cone head 36. The distance between the two cone heads 36 is the shortest, and the elastic member 38 is in an elastic deformation state. When the duckbill clamp 3 is opened, the movable jaw 31 moves away from the fixed jaw 32 and no longer blocks the cone head 36. The deformation of the elastic member 38 is restored, so that the two cone heads 36 move away from each other. The cone heads 36 located on different scrapers 35 respectively abut against the edges of the movable jaw 31 and the fixed jaw 32, and the spacing between the cone heads 36 increases. The cone heads 36 roll along the edge as the scraper 35 slides, thereby rubbing off the sticky wet mud on the edge. During the closing process of the duckbill clamp 3, the movable clamp 31 moves again and approaches the fixed clamp 32, so that the edge of the movable clamp 31 pushes against the inclined surface on the cone head 36, so that the distance between the two cone heads 36 is reduced, and the cone heads 36 move relatively while rolling along the edge, further cleaning the wet mud on the edge of the movable clamp 31 / fixed clamp 32 to avoid the gap being blocked when the duckbill clamp 3 is closed.

[0034] However, in the above process, since the scraper 35 divides and dredges the wet mud in the duckbill clamp 3 , the wet mud adheres to the bottom surface of the scraper 35 , which affects the rotation flexibility of the scraper 35 .

[0035] As an embodiment further provided by the present invention to solve the above-mentioned problem, a scraper 37 for scraping the end surface of the scraper blade 35 is provided on the cone head 36 .

[0036] Specifically, during the radial sliding of the slide rod 33, the two cone heads 36 move away from or approach each other, thereby driving the scraper 37 to slide on the scraper blade 35 and clean the bottom surface of the scraper blade 35, reducing the adhesion of wet mud. In addition, since the slag inlet chamber 7 is continuously sucked when the duckbill clamp 3 is closed, the wet mud is dried and agglomerated through the airflow, and the sliding of the scraper 37 is used to scrape off the lumpy wet mud, thereby ensuring the normal operation of the scraper blade 35.

[0037] As another embodiment further provided by the present invention, a clamping block 432 is slidably provided on the leveling shovel 4 to cooperate with the movable clamp 31; The leveling blade 4 is in a tilted state during the movable stroke of the movable jaw 31 .

[0038] Specifically, the leveling shovel 4 is rotatably arranged on the shaft cover 1 and has linearly arranged spike teeth on the bottom surface. The leveling shovel 4 is provided with a slide groove for sliding the block 432. The first end of the slide groove faces the leveling shovel 4, and the second end is opposite thereto. The leveling shovel 4 is provided with a third spring 431 for pulling the block 432 to remain at the first end, and the elasticity of the third spring 431 is weaker than the first spring 34. In the default state, the block 432 is located at the first end of the slide groove, and the leveling shovel 4 naturally falls under the action of gravity and remains parallel to the ground, shoveling up the raised soil slope. As the rotating disk 2 drives the movable clamp 31 to rotate, the movable clamp 31 is blocked by the block 432. Since the elasticity of the third spring 431 is weaker than the first spring 34, the third spring 431 is first blocked by the movable clamp 31 and stretched, and the block 432 slides to the second end of the slide groove, and drives the leveling shovel 4 to rotate upward and tilt, so that the shoveled soil slides down under the action of gravity. The block 432 stops sliding at the second end of the slide groove. At this time, the blocking force of the block 432 on the movable clamp 31 overcomes the elastic force of the first spring 34, so that the movable clamp 31 can move and rotate relative to the block 432. After the movable clamp 31 rotates to a certain angle, it disengages from the block 432, so that the block 432 loses its blocking effect, and the leveling shovel 4 falls again under the action of gravity, driving the spike teeth to fall and cut off the weeds on the ground. By repeatedly shoveling up and falling, the grass roots and other debris on the path are removed to avoid entanglement with weeds.

[0039] As another embodiment further provided by the present invention, it also includes a trigger unit for triggering the slide rod 33 to extend out of the turntable 2, which includes a second spring 12 arranged on the slide rod 33 and a trigger plate 312 arranged on the movable clamp 31, and the trigger plate 312 includes a unidirectional rotating flap 313.

[0040] Specifically, the second spring 12 is used to drive the slide bar 33 to slide toward the outer periphery of the rotating disk 2, and the trigger plate 312 includes an opening and a one-way flipping flap 313, such as Fig.11As shown, a card plate 314 is provided on the trigger plate 312 to limit the rotation direction of the flap 313, so that the flap 313 can only rotate toward the center of the turntable 2. When the scraper 37 is located at the tail end of the duckbill clamp 3, the slide bar 33 is in the default position. At this time, the flap 313 presses against the protrusion 331 to prevent the slide bar 33 from sliding down, and the second spring 12 is in a stretched and force-accumulated state. The card block 432 stops sliding when it reaches the second end of the slide slot. At this time, the blocking force of the card block 432 on the movable jaw 31 overcomes the elastic force of the first spring 34, so that the movable jaw 31 moves and drives the opening on the trigger plate 312 to move to correspond to the protrusion 331. At this time, the protrusion 331 is not blocked by the flap 313, and the deformation of the second spring 12 is restored, so that the slide bar 33 can slide toward the outer periphery of the rotating disk 2 under the release of the potential energy of the second spring 12. The slide bar 33 can automatically extend when the movable clamp 31 is opened. The elastic release of the spring makes the slide bar 33 have an impact force on the wet mud in the duckbill clamp 3, so as to better scrape the wet mud. When the slide bar 33 slides from the outer periphery of the rotating disk 2 to the center of the circle, the protrusion 331 pushes the flap 313 to rotate, and then the flap 313 presses against the protrusion 331 to avoid accidental touch.

[0041] As another embodiment further provided by the present invention, a stop block 311 is provided at the rear end of the movable clamp 31, and the leveling shovel 4 is slidably provided on the shaft cover 1, and a hook portion 42 is provided on the leveling shovel 4; The block 432 includes an arc surface 433 , and the arc surface 433 pushes the block 311 when the leveling shovel 4 is tilted to separate the block 311 from the movable clamp 31 , and the slide bar 33 abuts against the hook portion 42 and moves upward as the leveling shovel 4 loses weight.

[0042] Specifically, a rotating shaft is provided between the leveling shovel 4 and the hook-shaped portion 42, and a stopper 332 is provided on the side of the slide bar 33 facing the hook-shaped portion 42, and the stopper 332 slides on the turntable 2. The movable jaw 31 moves and drives the trigger plate 312 to slide, so that the opening on the trigger plate 312 corresponds to the protrusion 331 on the slide bar 33, and the slide bar 33 extends radially out of the turntable 2. At the same time, the stopper 311 fixedly provided on the movable jaw 31 rotates relative to the clamping block 432, so that the stopper 311 contacts and abuts against the arc surface 433. Since the arc surface 433 is inclined, the stopper 311 and the arc surface 433 slide in cooperation to push the arc surface 433, thereby pushing the clamping block 432 away from the stopper 311, driving the leveling shovel 4 to slide in the horizontal direction, so that the hook-shaped portion 42 hooks the stopper 332. Fig.12As shown. At this time, the leveling shovel 4 is in a tilted state, and the block 432 and the stopper 311 are separated. The leveling shovel 4 loses weight and falls after losing the block 432, thereby lifting the stopper 332 through the hook 42, and driving the slide bar 33 to slide radially from the outer periphery of the turntable 2 to the center of the circle. The convex block 331 drives the flap 313 to flip and is pressed by the flap 313. At this time, the slide bar 33 returns to the default position, so that the slide bar 33 can automatically retract due to the weight loss of the leveling shovel 4 after the trigger pop-up, and there is no need to assemble a driving source for lifting, thereby reducing production costs. When the leveling shovel 4 returns to a state parallel to the ground, it drives the hook 42 to disengage from the stopper 332 during the rotation process. Due to the large counterweight of the hook 42, the leveling shovel 4 in the parallel state slides and tilts toward the side where the hook 42 is located, so that the hook 42 is staggered from the stopper 332, and drives the block 432 to reset, and is blocked with the next movable clamp 31 and repeats the operation.

[0043] As another embodiment further provided by the present invention, a channel handle 41 is provided on the leveling shovel 4, and a rotating rake 44 driven to switch between two states of being parallel to or against the channel handle 41 is rotatably provided on the clamping block 432.

[0044] Specifically, when the leveling shovel 4 is in an inclined state, the soil scooped up inside automatically slides into the channel handle 41 under the action of gravity, and falls through the outlet opened on the channel handle 41 to the rear of the path of the rotating disk 2 to cover the soil. In the default state, the clamping block 432 is pulled by the elastic force of the third spring 431 and remains at the first end of the slide slot. When the clamping block 432 slides from the second end to the first end, it drives the rotating rake 44 to slide in the same direction in the channel handle 41 synchronously, and the rotating rake 44 contacts the blocking block 46 and rotates to abut against the channel handle 41 under the obstruction of the blocking block 46. Subsequently, the block 432 is pressed by the movable clamp 31 and slides to the second end, driving the rotating rake 44 to slide synchronously in the same direction. The rotating rake 44 in the resisting state scrapes the soil in the channel handle 41, allowing the soil to enter the outlet more quickly to avoid soil accumulation in the channel handle 41. During the sliding process, the rotating rake 44 contacts the guide block 45 provided in the channel handle 41 and is guided by the guide block 45 to slide, so that the rotating rake 44 rotates to be parallel to the channel handle 41. At this time, when the block 432 slides from the second end to the first end again, the rotating rake 44 in the parallel state will not scrape the soil. Figure 8 In the state shown, one-way scraping of the channel handle 41 is achieved.

[0045] As another embodiment further provided by the present invention, it also includes a soil discharge pipe 5 arranged on the shaft cover 1, and an elastic arc piece 53 for cleaning the head end of the duckbill clamp 3 and a hammer 54 for knocking the soil discharge pipe 5 are rotatably provided at the end thereof.

[0046] Specifically, it also includes a pressing wheel 6 for crushing the soil, a soil discharge pipe 5 is arranged below the outlet of the channel handle 41, and a dumping port 51 pointing to the rear of the turntable 2 is opened on the soil discharge pipe 5. When the leveling shovel 4 is tilted, the soil scooped up inside falls into the soil discharge pipe 5 through the channel handle 41 under the action of gravity, and then slides through the dumping port 51 to the rear of the turntable 2 path to be crushed by the pressing wheel 6, thereby covering the corn seeds. A rotating plate 52 is rotatably arranged at the end of the soil discharge pipe 5, and an elastic arc sheet 53 and a hammer 54 are respectively arranged at both ends of the rotating plate 52, the hammer 54 is closely attached to the soil discharge pipe 5, and a second torsion spring 55 is arranged on the rotating plate 52. During the rotation of the turntable 2, the head end of the duckbill clamp 3 is driven to pass through the middle of the elastic arc piece 53, and the head end of the duckbill clamp 3 is rubbed and cleaned by the sponge pad set on the elastic arc piece 53. Since the elastic arc piece 53 is set in an eight-shaped shape, the head end will first contact the larger opening, and penetrate into the narrower part during the rotation process to further clean the head end. In this process, the elastic arc piece 53 will adaptively deform and adjust according to the shape of the head end. At the same time, the head end of the duckbill clamp 3 drives the rotating plate 52 to flip, at which time the second torsion spring 55 deforms and accumulates force, and a gap appears between the hammer 54 and the soil discharge pipe 5. Then the head end of the duckbill clamp 3 is separated from the elastic arc piece 53, and the second torsion spring 55 is released, driving the hammer 54 to knock the soil discharge pipe 5, and the soil in the soil discharge pipe 5 is shaken off by knocking.

[0047] As another embodiment further provided by the present invention, the soil discharge pipe 5 is rotatably arranged relative to the shaft cover 1 and is swung by the duckbill clamp 3 .

[0048] Specifically, a fifth spring 56 is provided on the soil discharge pipe 5 for keeping the soil discharge pipe 5 tilted. The duckbill clamp 3 contacts the elastic arc piece 53 when the turntable 2 rotates, thereby driving the soil discharge pipe 5 to deflect upward. At this time, the fifth spring 56 is in a stretched state. When the duckbill clamp 3 is offset from the elastic arc piece 53, the fifth spring 56 will pull the soil discharge pipe 5 to fall and recover, so that the soil discharge pipe 5 continues to swing and shake the internal soil to the rear of the path to avoid soil accumulation in the soil discharge pipe 5.

[0049] Working principle: corn seeds pass through the seed wheel 11 and enter the feed chamber 22 opened on the turntable 2 one by one, and under the action of gravity, they roll into the duckbill clamp 3 in the closed state through the opening opened on the fixed clamp 32. As the turntable 2 drives the movable clamp 31 to rotate, the movable clamp 31 is blocked by the clamp block 432. Since the elasticity of the third spring 431 is weaker than that of the first spring 34, the third spring 431 is first blocked by the movable clamp 31 and stretched, and the clamp block 432 slides to the second end of the slide slot, and drives the leveling shovel 4 to rotate upward and tilt. The shoveled soil slides along the channel handle 41 into the soil discharge pipe 5 in the tilted state. The block 432 stops sliding when it is at the second end of the slide groove. At this time, the blocking force of the block 432 on the movable jaw 31 overcomes the elastic force of the first spring 34. The movable jaw 31 rotates relative to the fixed jaw 32, and drives the opening on the trigger plate 312 to move to correspond to the protrusion 331. The duckbill clamp 3 opens, and the protrusion 331 is not blocked by the flap 313. The deformation of the second spring 12 is restored, so that the slide rod 33 can slide toward the outer periphery of the turntable 2 under the release of the potential energy of the second spring 12.

[0050] During the sliding process of the slide bar 33 toward the outer periphery of the turntable 2, the scraper 35 abuts against the inner walls of the movable clamp 31 and the fixed clamp 32, and the direction of the friction force of the movable clamp 31 / fixed clamp 32 on the scraper 35 is opposite to the moving direction of the slide bar 33. At this time, the scraper 35 tilts, and the first torsion spring 333 begins to store deformation energy, and an acute angle pointing to the outer periphery of the turntable 2 is formed between the two scrapers 35, which divides and dredges the wet mud in the duckbill clamp 3 through this acute angle. When the scraper 35 detaches from the duckbill clamp 3, the potential energy of the first torsion spring 333 is released and drives the scraper 35 to return to a horizontal state, and the corn kernels are pressed into the soil through the shaking of the first torsion spring 333 when the elasticity is released.

[0051] The stopper 311 fixedly arranged on the movable clamp 31 rotates relative to the clamping block 432, so that the stopper 311 contacts and abuts against the arc surface 433. Since the arc surface 433 is inclined, the stopper 311 and the arc surface 433 slide together to push the arc surface 433, thereby pushing the clamping block 432 away from the stopper 311, driving the leveling shovel 4 to slide in the horizontal direction, so that the hook-shaped portion 42 hooks the stopper 332. Fig.12 shown.

[0052] The blocking block 432 and the resisting block 311 are disengaged, and the leveling shovel 4 loses the obstruction of the blocking block 432 and falls weightlessly, recovering to be parallel to the ground, shoveling up the raised earth slope, and in the process of falling, the blocking block 332 is lifted by the hook portion 42, and the slide bar 33 is driven to slide radially from the outer periphery of the turntable 2 to the center of the circle, and the protrusion 331 drives the flap 313 to flip and is pressed by the flap 313. At this time, the slide bar 33 returns to the default position, so that the slide bar 33 can automatically retract due to the weightlessness of the leveling shovel 4 after being triggered to pop up.

[0053] When the slide bar 33 slides toward the center of the turntable 2, the scraper blade 35 tilts again, and the tilting direction is opposite to the previous tilting direction, so that the two scraper blades 35 form an angle pointing to the center of the circle. The two scraper blades 35 squeeze the soil during the tilting process, and the squeezing direction is toward the central axis of the two scraper blades 35, so that the soil accumulates toward the center line, thereby preliminarily covering the corn kernels.

[0054] When the scraper 35 moves radially from the periphery to the tail end of the duckbill clamp 3, it is no longer pressed by the movable clamp 31 / fixed clamp 32, so that the scraper 35 returns to a horizontal state and the wet mud scraped during the process remains on the scraper 35 and is then sucked into the slag chamber 7.

[0055] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
