Description

Technical Field

[0001] This invention relates to the field of tobacco seedling transplanting technology, and in particular to a self-propelled rotary perforating tobacco seedling transplanting equipment and method. Background Technology

[0002] One method of transplanting tobacco seedlings into cellars involves ridging the land, drilling holes to form cellars, placing the tobacco seedlings into the cellars, and covering them with a film. Self-propelled tobacco seedling transplanting equipment can automate the transplanting process, greatly improving the automation level of flue-cured tobacco planting and increasing the efficiency of seedling transplanting.

[0003] The existing self-propelled tobacco seedling transplanting equipment uses different structures for drilling and seedling placement. These two structures are located at opposite horizontal positions. When placing the seedlings, the equipment needs to move forward a predetermined distance and perform secondary positioning. During continuous drilling and transplanting, the seedlings can be damaged due to uneven friction between the wheels and the ground, resulting in inaccurate secondary alignment and severe seedling leakage.

[0004] In addition, transplanting tobacco seedlings after drilling holes after rain or watering makes them more likely to survive. However, in areas where transplanting is done after rain or where the soil is very sticky, the inner walls of the wells become too smooth after drilling, which is not conducive to the roots of the tobacco seedlings adhering to the soil. This prevents the seedlings from being planted and growing normally. Drilling with an improved spiral drill bit can solve the problem of the inner walls of the wells to some extent. However, when the soil is sticky and moist, some clay adheres to the concave part of the spiral drill bit, affecting the subsequent roughing of the inner walls of the wells and ultimately affecting the normal planting and growth of the tobacco seedlings. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a self-propelled rotary drilling and transplanting device and method for tobacco seedlings. This invention can continuously complete the drilling of the well and the placement of tobacco seedlings by controlling the drilling device and the placement device to deflect at a predetermined angle, which greatly improves the efficiency of tobacco seedling transplanting. At the same time, it avoids the continuous adhesion of clay to the surface of the drilling device, which affects the standard and roughness of the subsequent well formation, and ensures the standard and vigorous growth of the tobacco seedlings.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] A self-propelled rotary perforating tobacco seedling transplanting device and method for well-cellar transplanting includes a walking main body and a perforating and dispensing main body. The perforating and dispensing main body includes a positioning platform, a perforating device, and a dispensing device. A positioning shaft is rotatably connected to the inner wall of the positioning platform, and an installation platform is provided on the side wall of the positioning shaft. The perforating device and the dispensing device are located on the outer surface of the installation platform and deflect along the same virtual circular trajectory. The perforating device includes a perforating end and a control component for controlling the extension and retraction of the perforating end. The perforating end includes a spiral part, and a cleaning device corresponding to the spiral part is also provided on the side wall of the positioning platform. Simultaneously, while controlling the perforating end to deflect to the side of the cleaning device to complete surface cleaning, the dispensing device dispenses the tobacco seedlings relative to the well-cellar.

[0008] Preferably, the cleaning device includes a cleaning positioning plate, and a cleaning nozzle is provided at the lower end of the cleaning positioning plate. The cleaning nozzle is connected to an air pumping pipe of an external air pumping device.

[0009] Preferably, the dispensing device includes a dispensing pipe with a dispensing opening on its side wall, an opening and closing component at the end of the dispensing pipe, and a feeding nozzle adapted to the dispensing opening on the side wall of the positioning platform.

[0010] Preferably, the opening and closing component includes an elastic airbag, which is normally inflated, and the cleaning positioning plate is internally embedded with a control pipe that is connected to and crosses with the pump air pipe, and the control pipe is connected to the elastic airbag.

[0011] Preferably, the opening and closing assembly further includes a control baffle that is inclinedly arranged inside the delivery pipe. The first side of the control baffle is movably connected to the inner wall of the delivery pipe, and the second side of the inner wall is connected to an elastic airbag.

[0012] Preferably, the punching end further includes a punching body that rotates around an axis, the punching body being conical, and the spiral part being installed at the top of the conical shape.

[0013] Preferably, the side wall of the punching body has an arc-shaped closed control groove, and the lower end of the cleaning device is provided with a control protrusion that matches the control groove, and the control protrusion has elasticity.

[0014] Preferably, the control component includes a telescopic component and an automatic force shaft. The drilling body has a hollow design, and the automatic force shaft is located inside the drilling body; it can rotate synchronously while sliding relative to the drilling body.

[0015] Preferably, the upper end of the walking body is provided with a delivery mechanism, which includes a delivery platform and a storage component disposed on the upper end of the delivery platform. The storage component has multiple empty spaces inside for storing tobacco seedlings.

[0016] The self-propelled rotary perforating tobacco seedling transplanting method, using the aforementioned self-propelled rotary perforating tobacco seedling transplanting equipment, includes the following steps: S1. The driving body moves to a predetermined position, and the perforating device is driven to a vertical position via a positioning shaft. The perforating end of the perforating device is controlled to move towards the ridge surface while continuously rotating, forming a well on the ridge surface; S2. After the well is formed, the perforating end is controlled to move away from the ridge surface. After the perforating end is misaligned with the ridge surface, the placement device is controlled to be aligned with the well to complete the placement of the tobacco seedlings via the positioning shaft; S3. While the placement device is aligned with the well, the perforating device is simultaneously deflected to the side of the cleaning device, and the surface clay is cleaned while the perforating device is rotated; S4. The above steps are repeated to continuously complete the formation of multiple wells and the placement of tobacco seedlings.

[0017] The beneficial effects of this invention are as follows:

[0018] Compared with existing technologies, this invention can automatically move between tobacco rows to complete drilling and seedling placement, achieving unmanned seedling transplanting. The drilling and placement devices are designed to be positioned on the same virtual circular surface. By controlling the deflection angle of the drilling and placement devices, drilling and seedling placement can be completed continuously. During drilling and seedling placement, the entire equipment does not need to move relative to the ground or undergo secondary positioning, greatly improving the efficiency and accuracy of seedling transplanting. Simultaneously, while the seedlings are being placed, the drilling device deflects to an outer position opposite the cleaning device, cleaning the surface of the drilling device at the same time as seedling placement. This prevents clay from continuously adhering to the drilling device surface, affecting the quality of subsequent seedling formation, further improving the efficiency of seedling transplanting and ensuring the standard and vigorous growth of the seedlings.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] To address the problems mentioned in the background art, see Appendix Figure 1 -Appendix Figure 10 The self-propelled rotary perforating tobacco seedling transplanting equipment includes a walking body 100 and a perforating and dispensing body. The perforating and dispensing body punches holes in the ridge surface to form a perforation, and then dispenses the tobacco seedlings into the perforation to complete the transplanting.

[0033] Specifically, the punching and dispensing main body includes a positioning platform 300, a punching device 400, and a dispensing device 500. The positioning platform 300 is rotatably connected to a positioning shaft 310, and an installation platform 311 is provided on the side wall of the positioning shaft 310. The punching device 400 and the dispensing device 500 are located on the outer surface of the installation platform 311 and deflect along the same virtual circular trajectory. Through the above structural design, by controlling the positioning shaft 310 to drive the installation platform 311 to deflect, the punching device 400 or the dispensing device 500 can be controlled to be opposite to the ridge surface. The punching device 400 is controlled to punch holes to form a well when it is opposite to the ridge surface, and the dispensing device 500 is controlled to be opposite to the ridge surface. The tobacco seedlings in the dispensing device 500 can automatically fall into the formed well under the action of gravity, realizing the automatic dispensing of tobacco seedlings.

[0034] Through the above structural design, the drilling of wells and the placement of tobacco seedlings can be carried out continuously and automatically, which greatly improves the efficiency of tobacco seedling transplanting. Here, the drilling device 400 and the placement device 500 move along the same virtual circular trajectory. Only the angle of their deflection needs to be controlled to complete the rapid positioning of the drilling device 400 and the placement device 500. There is no need to perform lateral positioning of the tobacco seedlings afterward, which further improves the efficiency of tobacco seedling transplanting.

[0035] The positioning shaft 310 here is an electrically controlled shaft. A drive assembly 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, so as to ultimately realize the deflection control of the punching device 400 and the delivery device 500.

[0036] Specifically, the drilling device 400 includes a drilling end 420 and a control component 410 for controlling the extension and retraction of the drilling end 420. The drilling end 420 includes a spiral part 421. By setting the spiral part 421, it is possible to efficiently drill holes in the ridge surface. At the same time, the surface of the spiral part 421 is relatively rough, which can prevent the inner wall of the formed well from being too smooth and thus avoid affecting the growth of tobacco seedling roots. A cleaning device 600 corresponding to the spiral part 421 is also provided on the side wall of the positioning platform 300. The cleaning device 600 can clean the spiral part 421 and its surrounding area, avoiding the residue of clay, facilitating continuous drilling operations, and ensuring the quality of each subsequent well.

[0037] During the transplanting of tobacco seedlings, the drilling end 420 is deflected to the side of the cleaning device 600 to complete surface cleaning, while the delivery device 500 is opposite to the well pit to deliver the tobacco seedlings. The delivery of tobacco seedlings is completed at the same time as cleaning, which further improves the efficiency of tobacco seedling transplanting. At the same time, the drilling device 400 is located on the outside for cleaning, so the cleaning material will not enter the already formed well pit and will not have any impact.

[0038] The angle between the drilling device 400 and the dispensing device 500 can be selected according to actual needs. The attached diagram shows a larger angle. When the angle between the drilling device 400 and the dispensing device 500 is larger, the drilling device 400 is located further away from the outer cleaning position, making it difficult for the cleaning material to enter the well cellar. This is suitable for environments with complex conditions and large changes in land slope. When the angle between the drilling device 400 and the dispensing device 500 is smaller, the required deflection angle between the drilling device 400 and the dispensing device 500 is smaller. Both can quickly move to the predetermined position to complete the drilling and dispensing of tobacco seedlings. The overall operation time is faster, which can further improve the efficiency of tobacco seedling transplanting.

[0039] In summary, through the above structural design, this invention can automatically move between tobacco rows and automatically complete the drilling and seedling placement, realizing unmanned seedling transplanting. The drilling device 400 and the placement device 500 are set on the same virtual circumferential surface. By controlling the drilling device 400 and the placement device 500 to deflect at a predetermined angle, the drilling of the seedbed and the placement of the seedlings can be completed continuously, which greatly improves the efficiency of seedling transplanting. At the same time, while the placement device 500 is placing the seedlings, the drilling device 400 deflects to the outer position opposite to the cleaning device 600, and the surface of the drilling device 400 is cleaned at the same time as the seedlings are placed. This avoids the continuous adhesion of clay to the surface of the drilling device 400, which affects the quality of the subsequent seedbed formation, and further improves the efficiency of seedling transplanting, ensuring the standard and vigorous growth of the seedlings.

[0040] Specifically, the cleaning device 600 includes a cleaning positioning plate 610, with a cleaning nozzle 621 at its lower end. The cleaning nozzle 621 is connected to an air pumping pipe 620 of an external air pumping device. The cleaning device 600 cleans the surface of the spiral part 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 part 421, achieving efficient cleaning of the surface of the spiral part 421. During the cleaning process, the spiral part 421 is deflected simultaneously, which can achieve continuous cleaning of various positions on the surface of the spiral part 421, greatly improving the cleaning efficiency.

[0041] Specifically, the feeding device 500 includes a feeding pipe 510 with a feeding opening 520 on its side wall. When the punching device 400 is in an inclined or horizontal position, tobacco seedlings are fed into the feeding pipe 510 through the feeding opening 520. An opening and closing component 530 is provided at the end of the feeding pipe 510. The opening and closing state of the end of the feeding pipe 510 can be controlled by the opening and closing component 530 to control the feeding time of the tobacco seedlings. The positioning platform 300 has a feeding nozzle 320 on its side wall that is adapted to the feeding opening 520.

[0042] During the automatic tobacco seedling delivery process, the tobacco seedlings at the top pass through the feed nozzle 320 and the delivery opening 520 into the delivery pipe 510. After the delivery pipe 510 is deflected to a vertical position, the tobacco seedlings move towards the end of the delivery pipe 510 under the action of gravity. Finally, the opening and closing component 530 controls the end of the delivery pipe 510 to be in an open state, allowing the tobacco seedlings to enter the well pit under the action of gravity, thus completing the automatic delivery of the tobacco seedlings.

[0043] By setting the opening and closing component 530, the timing of subsequent tobacco seedling placement can be controlled. The tobacco seedlings are placed only after the placement pipe 510 is aligned with the well, which avoids the tobacco seedlings being discharged too early and thus prevents inaccurate placement. This avoids accidents during tobacco seedling placement and greatly improves the efficiency of tobacco seedling placement.

[0044] The preferred opening and closing component 530 includes an elastic airbag, which is normally inflated. The inflated elastic airbag can form an obstacle at the bottom of the delivery pipe 510 to prevent the tobacco seedlings from falling out. The cleaning positioning plate 610 is internally embedded with a control pipe 630 that is connected to and crosses the pumping pipe 620. The control pipe 630 is connected to the elastic airbag. When the pumping pipe 620 blows out high-velocity gas, the gas inside the control pipe 630 can be drawn out by negative pressure under the action of Bernoulli's principle, and finally the gas in the elastic airbag is discharged, controlling the compression of the elastic airbag and realizing the automatic delivery of the tobacco seedlings.

[0045] After the outer wall is cleaned, the gas in the pump pipe 620 disappears, the pressure in the control pipe 630 is in a normal state, and the elastic airbag can reset under its own elastic force, thus achieving automatic reset.

[0046] Through the above structural design, the state of the elastic airbag can be controlled by the cleaning gas, realizing the automatic delivery of tobacco seedlings. During cleaning, both the punching device 400 and the delivery device 500 are in a stable predetermined position. Through the above 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.

[0047] The elastic airbags here can also be expanded and contracted through a separate pumping structure to achieve automatic control of tobacco seedling delivery.

[0048] Furthermore, the opening and closing assembly 530 also includes a control baffle that is inclinedly arranged inside the delivery pipe 510. The first side of the control baffle is movably connected to the inner wall of the delivery pipe 510, and the second side of the inner wall is connected to the elastic airbag.

[0049] The control baffle here can form a V-shaped temporary storage area within the delivery pipe 510. 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 contracts, the bottom of the control baffle can be staggered to control the rapid fall of the tobacco seedlings. At the same time, the surface of the baffle here is relatively smooth and is made of hard material. Compared with the simple elastic airbag, it can reduce interference with the delivery of tobacco seedlings and control the tobacco seedlings to fall into the well cellar in a predetermined posture (root-downward posture), further ensuring the accuracy of the tobacco seedling delivery.

[0050] The drilling end 420 also includes a drilling body 422 that rotates around the axis. The drilling body 422 is conical, and the spiral part 421 is installed at the top of the cone. The drilling body 422 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, avoiding the bottom being too smooth and affecting the rooting of the tobacco seedlings.

[0051] Furthermore, the top adopts a conical and cylindrical structure, which can ensure the relative integrity and smoothness of the inner and outer walls of the well, avoiding the failure of drilling due to the collapse of the well.

[0052] An arc-shaped closed control groove 423 is opened on the side wall of the drilling 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 elasticity.

[0053] While controlling the rotation of the drilling body 422, the control protrusion 640 can enter the control groove 423 and cooperate with it. By controlling the control groove 423, the control protrusion 640 limits the control groove 423. While the drilling body 422 rotates, it can move horizontally back and forth along the axis, achieving deep cleaning of various positions before and after the spiral part 421.

[0054] The arc angle and length range of the control groove 423 are adapted to the spiral part 421. Through the above structural design, the raised surface of the spiral part 421 can be controlled to be opposite to the cleaning nozzle 621, and the gas can clean the surface of the spiral part 421 more efficiently. The high-pressure gas is directly applied to the groove, achieving efficient, thorough and fast cleaning of residual clay.

[0055] Specifically, the control component 410 includes a telescopic component and an automatic force shaft. The drilling body 422 has a hollow design. The automatic force shaft is set to rotate synchronously with the drilling body 422 and can slide relative to it. The drilling body 422 is also provided with a mounting plate 424 on the side away from the spiral part 421. The drilling body 422 and the mounting plate 424 are rotatably connected. The mounting plate 424 can position the drilling body 422. While controlling the rotation of the drilling body 422, it can move along the axial direction to complete the drilling.

[0056] The surface of the punching body 422 can be provided with protrusions, and a matching sliding groove is provided on the inner wall of the punching body 422, which can control the punching body 422 to rotate while extending and retracting along the axial direction, thereby achieving efficient control.

[0057] The aforementioned telescopic components can be controlled by existing telescopic structures such as electrically controlled telescopic rods or pneumatic telescopic rods, which will not be elaborated further here.

[0058] A delivery mechanism 200 is provided on the upper part of the walking body 100. The delivery mechanism 200 includes a delivery platform 210 and a storage component 220 located on the upper part of the delivery platform 210. The storage component 220 has multiple spaces inside for storing tobacco seedlings.

[0059] The staff only needs to place the storage component 220 containing tobacco seedlings on the surface of the delivery platform 210 in advance. The storage component 220 can be moved to different positions by a robotic arm or a multi-joint drive device so that it can be opposite the feed nozzle 320. Under the action of gravity, the tobacco seedlings can automatically fall to the predetermined position, thus realizing the automatic delivery of tobacco seedlings.

[0060] The self-propelled rotary perforating tobacco seedling transplanting method, using the aforementioned self-propelled rotary perforating tobacco seedling transplanting equipment, includes the following steps:

[0061] S1. After the land is ridged, the driving body 100 moves to the predetermined position and drives the drilling device 400 to deflect to a vertical state through the positioning pivot 310. The drilling end 420 of the drilling device 400 moves towards the ridge surface while continuously rotating, forming a well on the ridge surface. The bottom of the formed well is rough and the top is relatively smooth, which is conducive to the rooting of tobacco seedlings while ensuring the strength of the well and preventing the well from collapsing.

[0062] S2. After the well is formed, control the drilling end 420 to move away from the ridge surface. After the drilling end 420 is offset from the ridge surface, control the delivery device 500 to be opposite to the well to complete the delivery of tobacco seedlings. The 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 at a predetermined angle, it can be directly opposite the well to complete the rapid delivery of tobacco seedlings.

[0063] S3. While the dispensing device 500 is facing the well, the drilling device 400 is simultaneously deflected to the side of the cleaning device 600. The drilling device 400 is rotated to clean the surface clay at the same time. This avoids clay residue inside the groove, ensures the normal progress of subsequent drilling, and also ensures that each well has the same quality and meets the requirements for tobacco seedling growth, ultimately ensuring the normal growth of tobacco seedlings.

[0064] S4. Repeat the above steps to continuously complete the formation of multiple wells and the placement of tobacco seedlings.

[0065] The self-propelled rotary drilling method for transplanting tobacco seedlings utilizes a self-propelled rotary drilling equipment that can automatically move between tobacco rows, automatically completing drilling and seedling placement. This achieves unmanned seedling transplanting, improving the efficiency and accuracy of drilling and seedling placement. During seedling placement, the spiral drill bit self-cleans, preventing the continuous adhesion of sticky soil and ensuring the quality of subsequent well formation, thus guaranteeing normal seedling establishment and growth.

[0066] 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 within the protection scope of the present invention.
