Description

Technical Field

[0001] The invention relates to the technical field of tobacco seedling transplanting, and in particular to self-propelled well-cellar rotary punching tobacco seedling transplanting equipment and a method. Background Art

[0002] One way to transplant tobacco seedlings into wells is to ridge and drill holes in the land to form wells, then place the tobacco seedlings into the wells and cover them with film. Self-propelled tobacco seedling well-cellar transplanting equipment can realize automated tobacco seedling well-cellar transplanting, greatly improving the degree of automation in flue-cured tobacco planting and improving tobacco seedling transplanting efficiency.

[0003] The existing self-propelled tobacco seedling well cellar transplanting equipment drills holes and releases tobacco seedlings through different structures. The two structures are located at two horizontal positions in the front and back. When the tobacco seedlings are released, the equipment needs to move a predetermined distance toward the front and needs to be positioned twice. This setting will cause the well cellar to be damaged due to inconsistent friction and slippage of the wheels on the ground during continuous well cellar drilling and transplanting, resulting in inaccurate secondary hole alignment when releasing the seedlings and serious seedling leakage.

[0004] In addition, tobacco seedlings are more likely to survive if holes are drilled after rain or after watering. However, for transplanting after rain or in areas with high soil viscosity, the inner wall of the well cellar is too smooth after drilling, which is not conducive to the attachment of the roots of the tobacco seedlings to the soil, that is, the tobacco seedlings cannot be established and grow normally. Drilling with an improved spiral drill bit can solve the problem of the inner wall of the well cellar being too smooth to a certain extent. However, when the soil is sticky and humid, some clay adheres to the concave part of the spiral drill bit, affecting the subsequent rough formation of the inner wall of the well cellar, and ultimately affecting the normal establishment and growth of the tobacco seedlings.

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and examples.

[0030] In order to solve the problems mentioned in the background technology, Figure 1 -Attached Figure 10 The self-propelled well-cellar rotary punching tobacco seedling transplanting equipment includes a walking body 100 and a punching and placing body. The punching and placing body punches holes on the ridge surface to form a well-cellar, and the tobacco seedlings are placed into the well-cellar to complete the transplanting.

[0031] Specifically, the punching and delivery body includes a positioning platform 300, a punching device 400 and a delivery device 500. The inner wall of the positioning platform 300 is rotatably connected to a positioning shaft 310, and the side wall of the positioning shaft 310 is provided with a mounting platform 311. The punching device 400 and the delivery device 500 are arranged on the outer surface of the mounting platform 311 and the two deflect along the same virtual circular trajectory. Through the above-mentioned structural design, by controlling the positioning shaft 310 to drive the deflection of the mounting platform 311, the punching device 400 or the delivery device 500 can be controlled to be opposite to the ridge surface, the punching device 400 is controlled to punch holes relative to the ridge surface to form a well cellar, and the delivery device 500 is controlled to be opposite to the ridge surface. The tobacco seedlings in the delivery device 500 can automatically fall into the formed well cellar under the action of gravity, thereby realizing automatic delivery of the tobacco seedlings.

[0032] Through the above-mentioned structural design, the well cellar drilling and tobacco seedling placement can be carried out continuously and automatically, which greatly improves the efficiency of tobacco seedling transplanting; the punching device 400 and the placement device 500 here move along the same virtual circular trajectory, and it is only necessary to control the deflection angle of the two to complete the rapid positioning of the punching device 400 and the placement device 500. There is no need to perform lateral positioning of the tobacco seedling placement subsequently, which further improves the efficiency of tobacco seedling transplanting.

[0033] The positioning shaft 310 here is an electrically controlled shaft. A driving component 330 can be installed on the inner wall of the positioning platform 300 to control the deflection angle of the positioning shaft 310. An angle detection element can be set between the positioning shaft 310 and the positioning platform 300 to determine the deflection angle of the positioning shaft 310, and finally realize the deflection control of the punching device 400 and the delivery device 500.

[0034] Specifically, the punching device 400 includes a punching end 420 and a control component 410 for controlling the extension and retraction of the punching end 420. The punching end 420 includes a spiral portion 421. By setting the spiral portion 421, the ridge surface can be efficiently drilled. At the same time, the surface of the spiral portion 421 is relatively rough, which can prevent the inner wall of the formed well from being too smooth, thereby avoiding affecting the growth of the tobacco seedling root system. A cleaning device 600 corresponding to the spiral portion 421 is also provided on the side wall of the positioning platform 300. The cleaning device 600 can clean the spiral portion 421 and the surrounding position, thereby avoiding clay residue, facilitating continuous punching operations, and ensuring the quality of each subsequent well.

[0035] During the process of transplanting tobacco seedlings, the punching end 420 is controlled to deflect to the side of the cleaning device 600 to complete surface cleaning, while the delivery device 500 is relative to the well cellar to complete the delivery of the tobacco seedlings. The delivery of tobacco seedlings is completed while cleaning, and the two are carried out simultaneously, which further improves the efficiency of transplanting tobacco seedlings. At the same time, the punching device 400 here is located on the outside for cleaning, and the materials dropped during cleaning will not enter the well cellar that has been formed and will not have any impact.

[0036] The angle between the punching device 400 and the delivery device 500 here can be selected according to actual needs. It is shown at a larger angle in the attached figure. When the angle between the punching device 400 and the delivery device 500 is larger, the punching device 400 is located farther away from the outer cleaning position, and the materials dropped by it are difficult to enter the well cellar. It is suitable for environments with complex environments and large changes in land inclination; when the angle between the punching device 400 and the delivery device 500 is smaller, the angle required for deflection between the punching device 400 and the delivery device 500 becomes smaller, and the two can quickly move to the predetermined position to complete the punching and delivery of tobacco seedlings. The overall operation time is faster, which can further improve the efficiency of tobacco seedling transplanting.

[0037] In summary, through the above-mentioned structural design, the present invention can automatically move between the tobacco ridges and automatically complete the drilling and the placement of tobacco seedlings in succession, realizing unmanned tobacco seedling transplanting. The punching device 400 and the placement device 500 are arranged on the same virtual circular surface. By controlling the punching device 400 and the placement device 500 to deflect by a predetermined angle, the drilling of the well cellar and the placement of tobacco seedlings can be continuously completed, greatly improving the efficiency of tobacco seedling transplanting; at the same time, when the placement device 500 places the tobacco seedlings, the punching device 400 is deflected to the outer position opposite to the cleaning device 600, and the surface of the punching device 400 is cleaned while the tobacco seedlings are being placed, avoiding the continuous adhesion of clay to the surface of the punching device 400 to affect the quality of subsequent well cellar formation, and further improving the efficiency of tobacco seedling transplanting, ensuring the standard and vigorous subsequent growth of the tobacco seedlings.

[0038] Specifically, the cleaning device 600 includes a cleaning positioning plate 610, and a cleaning nozzle 621 is provided at the lower end of the cleaning positioning plate 610. The cleaning nozzle 621 is connected to a pump air pipeline 620 with an external pump air device. The cleaning device 600 here completes the cleaning of the surface of the spiral portion 421 by spraying high-pressure gas. During the cleaning process, the high-pressure gas is sprayed downward from the cleaning nozzle 621, and the blown gas can directly act on the surface of the spiral portion 421 to achieve efficient cleaning of the surface of the spiral portion 421. During the cleaning process, the deflection of the spiral portion 421 is synchronously controlled to achieve continuous cleaning of various positions on the surface of the spiral portion 421, thereby greatly improving the cleaning efficiency.

[0039] Specifically, the delivery device 500 includes a delivery pipe 510, and a delivery opening 520 is opened on the side wall of the delivery pipe 510. When the punching device 400 is in an inclined or horizontal position, the tobacco seedlings are delivered into the delivery pipe 510 from the delivery opening 520. An opening and closing component 530 is provided at the end of the delivery pipe 510. The opening and closing component 530 can control the opening and closing state of the end of the delivery pipe 510 to realize the control of the delivery time of the tobacco seedlings; the side wall of the positioning platform 300 is provided with a discharge nozzle 320 adapted to the delivery opening 520.

[0040] During the process of automatic delivery of tobacco seedlings, the tobacco seedlings at the top pass through the discharge nozzle 320 and the delivery opening 520 in turn and enter the delivery pipe 510. After the delivery pipe 510 is deflected to a vertical state, the tobacco seedlings move toward the end of the delivery pipe 510 under the action of gravity. Finally, the end of the delivery pipe 510 is controlled to be in an open state through the opening and closing component 530. The tobacco seedlings can enter the well cellar under the action of gravity, completing the automatic delivery of the tobacco seedlings.

[0041] By setting the opening and closing component 530, the time of subsequent release of tobacco seedlings can be controlled. The release of tobacco seedlings can be completed after the release pipe 510 is opposite to the well cellar, avoiding the tobacco seedlings being discharged too early and unable to be released accurately, avoiding accidents in the release of tobacco seedlings, and greatly improving the efficiency of tobacco seedling release.

[0042] Preferably, the opening and closing component 530 includes an elastic airbag, which is in an expanded state under normal circumstances. The expanded elastic airbag under normal circumstances can form an obstacle at the bottom of the delivery pipe 510 to prevent the tobacco seedlings from falling out; a control pipe 630 that is connected to the pump air pipe 620 and arranged crosswise is embedded in the cleaning positioning plate 610. The control pipe 630 is connected to the elastic airbag. When the pump air pipe 620 blows out high-flow gas, the gas inside the control pipe 630 here can be drawn out by negative pressure under the action of the Bernoulli principle, and finally the gas in the elastic airbag is discharged, the compression of the elastic airbag is controlled, and the automatic delivery of the tobacco seedlings is realized.

[0043] After the outer wall is cleaned, the gas in the pump air pipe 620 disappears, the pressure in the control pipe 630 is in a normal state, and the elastic airbag can be reset under the action of its own elastic force, thereby achieving automatic reset.

[0044] Through the above-mentioned structural design, the state of the elastic airbag can be controlled by cleaning gas, thereby realizing automatic delivery of tobacco seedlings; during cleaning, the punching device 400 and the delivery device 500 are both in stable predetermined positions. Through the above-mentioned structural design, the efficiency of tobacco seedling transplanting is further improved, the difficulty of control is reduced, and the accuracy of tobacco seedling delivery is improved.

[0045] The elastic airbag here can also be expanded and contracted by a separate pump structure to achieve automatic delivery control of the tobacco seedlings.

[0046] Furthermore, the opening and closing assembly 530 further includes a control baffle arranged obliquely in the delivery pipe 510, wherein a first side of the control baffle is movably connected to the inner wall of the delivery pipe 510, and a second side inner wall is connected to the elastic airbag.

[0047] The control baffle here can form a temporary storage area with a V-shaped cross-section in the delivery pipe 510, and the shape of its inner wall can be adaptively designed according to the size of the tobacco seedlings. Through the above structural design, after the elastic airbag is controlled to shrink, the bottom of the control baffle can be staggered to control the tobacco seedlings to fall quickly; at the same time, the surface of the baffle here is relatively smooth and is made of hard material. Compared with a simple elastic airbag, it can reduce the interference with the delivery of tobacco seedlings, and can control the tobacco seedlings to fall into the well cellar in a predetermined posture (root-facing posture), further ensuring the accuracy of tobacco seedling delivery.

[0048] The punching end 420 also includes a punching body 422 that rotates around an axis. The punching body 422 is conical, and the spiral part 421 is installed at the top of the cone. The punching body 422 here also includes a cylindrical part. Through the above structural design, the spiral part 421 at the end can form a rough structure at the bottom of the well cellar, preventing the bottom from being too smooth and affecting the rooting of the tobacco seedlings.

[0049] In addition, the top adopts a conical and cylindrical structure, which can ensure that the outer and inner walls of the well cellar are relatively complete and smooth, and avoid the failure of drilling caused by the collapse of the well cellar.

[0050] An arc-shaped closed control groove 423 is formed on the side wall of the punching body 422 , and a control protrusion 640 adapted to the control groove 423 is provided at the lower end of the cleaning device 600 . The control protrusion 640 has telescopic elasticity.

[0051] While controlling the rotation of the punching body 422, the control protrusion 640 here can enter the control groove 423 and cooperate with the control groove 423. The control groove 423 is limited by the control protrusion 640. While the punching body 422 rotates, it can move horizontally back and forth along the direction of the axis, thereby achieving deep cleaning of various positions before and after the spiral part 421.

[0052] The arc angle and length range of the control groove 423 here are adapted to the spiral portion 421. Through the above-mentioned structural design, the raised surface of the spiral portion 421 can be controlled to be opposite to the cleaning nozzle 621, and the gas can clean the surface of the spiral portion 421 more efficiently. The high-pressure gas is directly applied to the position of the groove, thereby achieving efficient, thorough and rapid cleaning of residual clay.

[0053] Specifically; the control component 410 includes a telescopic component and an automatic power shaft. The punching body 422 is hollow in design. The automatic power shaft is set on the punching body 422 and can slide relatively while rotating synchronously. The punching body 422 here is also provided with a mounting plate 424 on the side away from the spiral portion 421. The punching body 422 and the mounting plate 424 are rotatably connected. The punching body 422 can be positioned through the mounting plate 424. While controlling the rotation of the punching body 422, it can move along the axial direction to complete the punching.

[0054] The surface of the punching body 422 here can be provided with a protrusion, and the inner wall of the punching body 422 is provided with a corresponding sliding groove, which can control the rotation of the punching body 422 while telescopically moving along the axial direction to achieve efficient control.

[0055] The telescopic assembly can be controlled by an existing telescopic structure such as an electric telescopic rod or a pneumatic telescopic rod, which will not be described in detail here.

[0056] A delivery mechanism 200 is provided at the upper end of the walking body 100 . The delivery mechanism 200 includes a delivery platform 210 and a storage component 220 provided at the upper end of the delivery platform 210 . A plurality of spaces are formed inside the storage component 220 for storing tobacco seedlings.

[0057] The staff only needs to place the storage component 220 containing the tobacco seedlings on the surface of the delivery platform 210 in advance. The storage component 220 can be controlled to move to different positions through a manipulator or a multi-joint drive device, so that it can be opposite to the discharge nozzle 320. The tobacco seedlings can automatically fall to the predetermined position under the action of gravity, thereby realizing the automatic delivery of the tobacco seedlings.

[0058] The self-propelled rotary perforated tobacco seedling transplanting method using the self-propelled rotary perforated tobacco seedling transplanting equipment includes the following steps: S1. After the land is ridged, the walking body 100 is driven to move to a predetermined position, and the punching device 400 is driven to deflect to a vertical state through the positioning shaft 310. The punching end 420 of the punching device 400 is controlled to move toward the ridge surface while continuously rotating to form a well on the ridge surface. The formed well has a rough bottom and a relatively smooth top, which is conducive to the rooting of tobacco seedlings while ensuring the strength of the well and avoiding the collapse of the well.

[0059] S2. After the well is formed, the drilling end 420 is controlled to move in the direction away from the ridge surface. After the drilling end 420 is offset from the ridge surface, the delivery device 500 is controlled by the positioning shaft 310 to be relative to the well to complete the delivery of the tobacco seedlings. Here, the deflection angle of the positioning shaft 310 is determined by the angle between the drilling device 400 and the delivery device 500. After the delivery device 500 rotates to a predetermined angle, it can be directly opposite to the well to complete the rapid delivery of the tobacco seedlings.

[0060] S3. When the delivery device 500 is opposite to the well, the punching device 400 is synchronously deflected to the side of the cleaning device 600, and the surface clay is cleaned while controlling the rotation of the punching device 400; this avoids clay residue inside the groove, ensures the normal progress of subsequent punching, and also ensures that the quality of each well is the same and meets the requirements for the growth of tobacco seedlings, ultimately ensuring the normal growth of tobacco seedlings.

[0061] S4. Repeat the above steps to continuously complete the formation of multiple wells and pits and the placement of tobacco seedlings.

[0062] The self-propelled well-cellar rotary drilling tobacco seedling transplanting method uses a self-propelled well-cellar rotary drilling tobacco seedling transplanting equipment, which can automatically walk between tobacco ridges, automatically complete drilling and placement of tobacco seedlings, realize unmanned transplanting of tobacco seedlings, and improve the efficiency and accuracy of drilling and placement of tobacco seedlings; when the tobacco seedlings are placed, the spiral drill bit is self-cleaned to avoid the continuous adhesion of sticky soil, ensure the quality of subsequent well-cellar formation, and ensure the normal planting and growth of tobacco seedlings.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

After the punching end (420) is offset from the ridge surface, the placement device (500) is controlled by the positioning shaft (310) to be relative to the well to complete the placement of the tobacco seedlings. S3, while the delivery device (500) is facing the well, the punching device (400) is synchronously deflected to the side of the cleaning device (600), and the punching device (400) is controlled to rotate while completing the cleaning of the surface clay; S4. Repeat the above steps to continuously complete the formation of multiple wells and pits and the placement of tobacco seedlings.
