Description

Technical Field

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

[0002] Transplanting tobacco seedlings in wells is a widely used method of flue-cured tobacco cultivation. In order to meet the needs of the growth of tobacco seedlings after transplanting, there are certain requirements for the size of the transplanting holes, and the depth is relatively large. For the ridges to be drilled, the soil on the top is dry, especially for soil with lumps and some gravel. After the drilling equipment is pulled out after drilling, the unstable part around the transplanting hole is easy to collapse into the transplanting hole, resulting in unqualified size of the transplanting hole, affecting the subsequent placement and growth of the tobacco seedlings.

[0003] Some integrated transplanting devices have modified the drilling device by referring to the duckbill pliers. After the drilling is completed, the end of the drilling device is controlled to open to form an opening for the seedlings to pass through. Through the above-mentioned structural design, the seedlings can be accurately placed without removing the drilling device. However, when trying to drill holes in the tobacco seedling well, if the drilling depth is too large, it is difficult to stably open this type of drilling equipment due to the high pressure on the outside. During use, the equipment structure is damaged quickly and has a short service life. In addition, the duckbill pliers-type drilling structure will damage the local surface of the inner wall of the well during the opening process, affecting the stability of the inner wall structure of the well, and ultimately affecting the quality of tobacco seedling growth.

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0034] Transplanting tobacco seedlings is an important part of flue-cured tobacco cultivation, which is related to the quality and yield of tobacco leaves. With the increase in yield, traditional manual transplanting technology can hardly meet the needs of industry development.

[0035] Transplanting tobacco seedlings in wells is a widely used method of flue-cured tobacco cultivation. In order to meet the needs of tobacco seedlings' growth after transplanting, the size of the transplanting hole has certain requirements (depth of about 18CM, diameter of about 9CM). The depth is relatively large. For some dry soils, especially soils with lumps and some gravel, after the drilling equipment is pulled out after drilling, the unstable part around the transplanting hole is easy to collapse into the transplanting hole, resulting in unqualified size of the transplanting hole, affecting the subsequent placement and growth of the tobacco seedlings.

[0036] Some integrated transplanting devices have modified the drilling device by referring to the duckbill pliers. After the drilling is completed, the end of the drilling device is controlled to open to form an opening for the seedlings to pass through. Through the above-mentioned structural design, the seedlings can be accurately placed without removing the drilling device. However, when trying to drill holes in the tobacco seedling well, if the drilling depth is too large, it is difficult to stably open this type of drilling equipment due to the high pressure on the outside. During use, the equipment structure is damaged quickly and has a short service life. In addition, the duckbill pliers-type drilling structure will damage the local surface of the inner wall of the well during the opening process (especially the loose and dry inner wall of the well), affecting the stability of the inner wall structure of the well, and ultimately affecting the quality of tobacco seedling growth.

[0037] In order to solve the above problems, refer to the attached Figure 1 -Attached Fig.13 A self-propelled tobacco seedling drilling and transplanting integrated device includes a walking body 100, the walking body 100 includes a walking part 120 and a mounting part 110, a drilling device 500 for drilling holes is installed at the lower end of the mounting part 110, the drilling device 500 includes a drilling body 530, the upper end of the drilling body 530 is connected with a delivery pipe 510 for delivering tobacco seedlings, and a conical drill bit assembly 540 is arranged at the lower end of the drilling body 530; by controlling the drilling device 500 to rotate and move downward in a directional manner, the drilling of soil can be completed, and the tobacco seedlings can be delivered through the delivery pipe 510, so that the integrated design of tobacco seedling drilling and transplanting can be realized, and the end of the drill bit assembly 540 here is movably designed to allow the tobacco seedlings to pass through.

[0038] Specifically, the drill bit assembly 540 includes a drill bit base 541 fixedly connected to the drilling body 530, and a accommodating chamber 5411 is formed inside the drill bit base 541. A plurality of drill bit ends 542 are slidably connected to the inner wall of the accommodating chamber 5411, and a first control device 600 for controlling the linear movement of the drill bit end 542 is also provided on the inner wall of the accommodating chamber 5411. The moving position of the drill bit end 542 can be controlled by the first control device 600; wherein, when drilling, the plurality of drill bit ends 542 are controlled to extend to form a conical closed drill bit assembly 540, and at this time, the drill bit assembly 540 can complete continuous drilling of the soil to form a transplanting hole; when the tobacco seedlings are released, the plurality of drill bit ends 542 are controlled to contract to form a release opening for the tobacco seedlings to pass through, and the tobacco seedlings can pass through the release opening under the action of gravity through the release pipe 510 and directly fall into the transplanting hole to complete the integrated design of tobacco seedling drilling and transplanting.

[0039] Drilling protrusions are integrally formed on the outer sides of the drill base 541 and the drill end 542 to enhance the ability to drill holes in the soil; during the process of placing the tobacco seedlings, some nutrient soil can also be placed, which is beneficial to the growth of the tobacco seedlings.

[0040] In summary, through the above-mentioned structural design, by controlling the extension of multiple drill bit ends 542, a conical drill bit assembly 540 can be formed, which is convenient for drilling holes in the soil. Moreover, compared with the drill bit modified from the duckbill pliers, the drill bit assembly 540 with the above-mentioned structural design has a smoother and more continuous appearance, which reduces the resistance to drilling. In particular, by controlling the contraction of multiple drill bit ends 542, the drill bit end 542 can be contracted to the hidden design in the accommodating chamber 5411 according to a predetermined path. In the deep soil, there is no need to open toward the outside, which effectively solves the problem of high pressure on the outside and difficulty in opening. The drill bit end 542 can be used in a long-term cycle and has a long service life. At the same time, through the above-mentioned structural design, a larger transfer hole can be drilled on the soil surface. After drilling, the drill bit end 542 is hidden and contracted, which will not affect the inner wall of the transfer hole, thereby ensuring the relative stability of the inner wall of the transfer hole and improving the quality of subsequent tobacco seedling growth.

[0041] It should be noted here that the drill bit end 542 is located above the soil during the extension process, and there is no soil resistance. The retraction control of the drill bit end 542 is convenient and fast. The drill bit end 542 here can select the 4 groups shown in the figure, and other numbers can also be selected. In the design process, it is necessary to control multiple drill bit ends 542 to be located on the virtual cone surface after being extended, so as to ensure the integrity and continuity of the overall structure and reduce the resistance during the drilling process.

[0042] Please refer to the attached Fig.11 And attached Fig.13 Specifically, the first control device 600 includes a plurality of positioning assemblies 620 fixedly connected to the drill bit end 542, the positioning assemblies 620 are slidably connected to the inner wall of the accommodating chamber 5411, the positioning assemblies 620 include a plurality of arc-shaped positioning sliders 621 and an arc-shaped positioning guide rod 622, the positioning sliders 621 are slidably connected to the positioning guide rods 622, the number of positioning sliders 621 and positioning guide rods 622 here is selected to be consistent with the number of drill bit ends 542, and a plurality of positioning sliders 621 are fixedly connected to the corresponding drill bit ends 542.

[0043] The multiple positioning sliders 621 are in a state of being pressed against each other near the outer side of the bottom, and can form a circular sealing ring, which effectively prevents the soil from entering during the drilling process; at the same time, in the process of the positioning slider 621 contracting toward the inside, the multiple positioning sliders 621 are separated from each other to meet the control requirements of the inner wall of the conical drill bit base 541. The multiple positioning sliders 621 can be guided and limited by the multiple positioning guide rods 622, thereby ensuring the stability of the positioning slider 621 during the sliding process.

[0044] Please refer to the attached Fig.12Specifically, the first control device 600 also includes a telescopic control rod 610 located inside the accommodating chamber 5411, and the telescopic control rod 610 includes a telescopic cylinder 611. The inner wall of the telescopic cylinder 611 is sealed and slidably connected with a control piston 612. A first connecting rod 613 is fixed to the side wall of the first end of the control piston 612. The first connecting rod 613 is connected to the drill bit end 542. Through the above structure, the drill bit end 542 can be controlled to move linearly according to a predetermined trajectory. The first connecting rod 613 here is connected to the positioning assembly 620, and the positioning assembly 620 can be controlled to move linearly. The above-mentioned telescopic control rod 610 can be symmetrically arranged in two groups to ensure that the forces on both sides are relatively consistent, thereby ensuring the stability of the positioning assembly 620 and the drill bit end 542 during the movement.

[0045] Furthermore, a second end of the control piston 612 is fixedly connected to a second connecting rod 614, and a disturbance rod is fixedly connected to the side of the second connecting rod 614 away from the control piston 612. The end portion of the disturbance rod can penetrate the first control device 600 and extend to the outside. During the process of controlling the telescopic control rod 610 and the drill end 542 to retract, the tobacco seedlings are placed at this stage. After the tobacco seedlings are placed and transplanted, the drill end 542 is controlled to move upward in a retracted state, and the disturbance rod outside the telescopic control rod 610 is in an extended state (see attached Fig.11 ), the extended disturbance rod can exert force on the surrounding soil. During the extraction process of the drill assembly 540, the state of the surrounding soil can be changed to cover the roots and stems of the tobacco seedlings, further ensuring the stability of the tobacco seedlings. The transplanting staff does not need to perform subsequent processing, which further improves the efficiency of tobacco seedling transplanting.

[0046] A delivery device 200 for delivering tobacco seedlings is provided at the upper end of the mounting portion 110, and a delivery control device 300 is provided between the delivery device 200 and the delivery pipe 510. The delivery device 200 can accommodate tobacco seedlings. The delivery device 200 here includes a delivery platform 210 and a storage box 220. The inner wall of the storage box 220 is provided with a plurality of feed openings 221 in a grid shape, and the feed openings 221 are used to store a single tobacco seedling. A delivery circular opening 211 is designed on the surface of the delivery platform 210, and the feed opening 221 is opposite to the delivery circular opening 211. The tobacco seedlings move downward under the action of gravity; the delivery control device 300 is located on the moving path of the tobacco seedlings, and can limit the movement of the tobacco seedlings to prevent the tobacco seedlings from falling into the drill assembly 540 too early.

[0047] The delivery control device 300 includes a delivery valve group 320 and a first electric control device 310 for controlling the opening and closing of the delivery valve group 320, and also includes a telescopic control device 330 connected to the delivery valve group 320. The telescopic control device 330 is electrically connected to the telescopic control rod 610 for adjusting the telescopic control rod 610. Through the above-mentioned structural design, when the delivery valve group 320 is in an open state, the telescopic control rod 610 can be controlled to retract, and the multiple drill bit ends 542 at the bottom can be controlled to be in a retracted state, thereby realizing the delivery of tobacco seedlings; in the drilling stage, the delivery valve group 320 is in a closed state, and the telescopic control rod 610 is in an extended state, which ensures the normal drilling and avoids the premature delivery of tobacco seedlings.

[0048] Through the above structural design, the contraction of the drill bit end 542 and the placement of the tobacco seedlings can be controlled in an integrated manner, thereby ensuring the stability of the placement of the tobacco seedlings and the normal drilling and transplanting of the tobacco seedlings.

[0049] It should be noted here that the delivery valve group 320 here includes a shell and an internal valve body. The valve body can be selected as a rotary valve, and its surface has an opening for the tobacco seedlings to pass through. Controlling the position of the rotary valve can control the delivery of the tobacco seedlings.

[0050] A plurality of storage boxes 220 can be designed on the upper end of the delivery platform 210. The storage boxes 220 here are cooperatively controlled by transverse electric joints and longitudinal electric joints, so that a plurality of discharge ports 221 are successively opposite to the delivery circular port 211, so as to realize the orderly delivery of tobacco seedlings. During the process of punching and transplanting tobacco seedlings, the staff only needs to replace the storage boxes 220 in time.

[0051] See attached Figure 7 And attached Fig.12 , and further; a first control chamber 610-1 and a second control chamber 610-2 are formed inside the control piston 612 and the telescopic cylinder 611, wherein, when the delivery valve group 320 is in an open state, a control medium is pumped into the first control chamber 610-1 through the telescopic control device 330, and when the delivery valve group 320 is in a closed state, a control medium is pumped into the second control chamber 610-2 through the telescopic control device 330. The above-mentioned control medium can be selected as control oil, and the pressure on both sides of the control piston 612 is changed to achieve rapid adjustment and control of the position of the control piston 612, thereby achieving rapid opening and closing of the drill bit end 542; at the same time, a second connecting rod 614 and a first connecting rod 613 are respectively connected to both sides of the control piston 612, and the internal cross-section of the telescopic cylinder 611 is small, which further accelerates the opening and closing speed of the drill bit end 542.

[0052] Specifically, the telescopic control device 330 includes a control shell 331, the inner wall of which is rotatably connected to a control shaft 335 connected to the delivery valve group 320, the inner wall of the control shell 331 is also fixed with a first control plate 332 and a second control plate 333, a third control plate 334 located between the first control plate 332 and the second control plate 333 is fixed with a side wall of the control shaft 335, a third control chamber 332-1 communicating with the first control chamber 610-1 is formed between the first control plate 332 and the third control plate 334, a fourth control chamber 333-1 communicating with the second control chamber 610-2 is formed between the second control plate 333 and the third control plate 334, wherein the fourth control chamber 333-1 and the third control chamber 332-1 are relatively closed chambers.

[0053] During the rotation of the release valve group 320, the control shaft 335 can be driven to rotate synchronously, thereby controlling the third control plate 334 to deflect toward the second control plate 333 or the first control plate 332, thereby adjusting the size of the fourth control chamber 333-1 and the third control chamber 332-1 to achieve a rapid adjustment process; the control oil can be placed in the fourth control chamber 333-1, the third control chamber 332-1, or an elastic bag can be installed inside the two to further avoid leakage of the control oil.

[0054] During the process of the third control plate 334 deflecting toward the second control plate 333, the control oil in the fourth control chamber 333-1 can be pumped into the second control chamber 610-2, and the drill end 542 can be controlled to extend. During the process of the third control plate 334 deflecting toward the first control plate 332, the drill end 542 can be controlled to retract.

[0055] Through the above-mentioned structural design, in the process of controlling the rotation of the release valve group 320, the telescopic state of the telescopic control rod 610 can be adjusted by controlling the oil, and the telescopic state of the drill bit end 542 can be controlled. Through the above-mentioned structural design, the flow of the control oil can be adjusted to achieve efficient flow control. It is simple and clever, does not require the design of too many electronic structures, has good control stability, and high adjustment efficiency.

[0056] Furthermore, the delivery pipe 510 is a retractable pipe, which includes a delivery end 511 extending into the interior of the drilling body 530, a delivery channel for the tobacco seedlings to pass through is formed inside the delivery end 511, a guide channel 531 for liquid to pass through is formed between the outer wall of the delivery end 511 and the inner wall of the drilling body 530, the upper end of the drilling body 530 is rotatably connected to a connector 520 connected to the guide channel 531, and the upper end of the connector 520 is connected to a pumping device, which can pump water, fertilizer and rooting water into the guide channel 531.

[0057] An opening is provided at the bottom of the delivery end 511. During the process of drilling and delivering the tobacco seedlings, the tobacco seedlings first pass through the delivery end 511 and come into contact with the soil. Subsequently, water and fertilizer are controlled to pass through the connector 520 and the diversion channel 531, and finally flow out from the inside of the drill end 542 and accurately flow to the root position of the tobacco seedlings, thereby realizing an integrated design of drilling holes for tobacco seedlings, delivering and transplanting, and watering, and further improving the efficiency of tobacco seedling transplanting.

[0058] It should also be noted that, through the above-mentioned structural design, the delivery end 511 can reduce the internal space of the drilling body 530, can guide the tobacco seedlings during the descent process, prevent the tobacco seedlings from flipping over, and ensure the accuracy of the tobacco seedling transplanting position; at the same time, the liquid in the diversion channel 531 can flush some impurities inside the drill bit base 541, avoid internal blockage, and ensure the normal transplanting of tobacco seedlings.

[0059] It should also be noted that a second control device 400 is arranged between the mounting portion 110 and the drilling device 500, and the second control device 400 is used to control the lifting, movement and rotation of the drilling device 500. Through the above-mentioned structural design, the relative movement between the drilling device 500 and the soil can be controlled to ensure the depth of the drilling hole.

[0060] Specifically, the second control device 400 includes a positioning frame 410, and a control platform 420 is slidably connected to the surface of the positioning frame 410. The drilling device 500 is rotatably connected to the control platform 420. A second electric control device 440 for driving the drilling device 500 to rotate is arranged on the upper end of the control platform 420. A telescopic rod 430 is arranged between the control platform 420 and the positioning frame 410. The telescopic rod 430 can be used to adjust the control platform 420 and the drilling device 500 to move up and down as a whole to ensure the depth of the drilling; the second electric control device 440 can be used to control the directional rotation of the drilling device 500, so as to destroy the internal structure of the soil and ensure the normal drilling.

[0061] It should also be noted that the positioning frame 410 here includes a first positioning plate 411, a positioning rod 412, a second positioning plate 414 and other structures. The positioning rods 412 are arranged in multiples and can guide the mobile key control platform 420. An elastic element 413 can also be mounted on the outside of the positioning rods 412 to perform reset control on the control platform 420.

[0062] The present invention is further described below in conjunction with the punching and transplanting method.

[0063] Using the above-mentioned integrated device includes the following steps:

[0064] S1. Control the drilling device 500 to move to a predetermined position through the walking body 100, control the multiple drill bit ends 542 to extend to form a conical closed drill bit assembly 540, and control the drilling device 500 to directional rotate and descend to achieve drilling of the soil.

[0065] S2. After the drilling is completed, the multiple drill bit ends 542 are controlled to contract to form a delivery opening for the tobacco seedlings to pass through, and the tobacco seedlings are delivered into the delivery pipe 510 and delivered into the transplanting hole under the action of gravity.
