Description

Technical Field

[0001] This invention relates to the field of sugarcane seedling transplanting technology, and more particularly to a sugarcane seedling transplanting planter. Background Technology

[0002] In sugarcane cultivation, the sugarcane growth cycle is relatively long. If sown directly in the field, the land will be idle for a relatively long time. Therefore, the method of raising seedlings first and then transplanting is adopted. During the seedling stage, a large number of sugarcane seedlings can be cultivated in a small area of ​​seedbed. Once the sugarcane seedlings have grown to a certain size, they can be transplanted to the field. This can effectively shorten the land occupation time and improve the land multiple cropping index and utilization rate. At the same time, in order to facilitate seedling management, raising seedlings in the seedbed in a concentrated manner makes it easier to carry out management operations such as watering, fertilization, weeding, and pest and disease control. This is conducive to cultivating uniform and robust sugarcane seedlings. In contrast, sowing directly in the field makes seedling management more difficult and makes it difficult to ensure that each sugarcane seedling receives good care. Therefore, it is necessary to transplant the sugarcane seedlings.

[0003] Sugarcane stems have buds on their nodes, and the stem is its main reproductive organ. The surface of the sugarcane stem has many nodes, each with a bud containing an undeveloped bud. When sugarcane is planted in a suitable environment, under appropriate conditions of water, temperature, and light, these buds will sprout and grow into new sugarcane seedlings. These seedlings are then transplanted to designated planting areas. However, in practice, planters need to use cutting tools to remove the stem nodes with seedlings, then turn over the soil in the designated transplanting area and plant the seedlings. This requires holding both cutting and turning tools, and switching between them is inconvenient, making it difficult for a single person to complete the transplanting work. Therefore, this patent application designs a sugarcane seedling transplanter that allows for the removal and transplanting of sugarcane seedlings by a single person. Summary of the Invention

[0004] This invention provides a sugarcane seedling transplanter to solve the aforementioned technical problems.

[0011] Preferably, the adjusting cylinder has an internal chamber, forming a shell-like structure that matches the shape of the planting rod. Adjusting plates are provided on both the front and rear sides of the bottom of the adjusting cylinder, positioned between the two clamping components. Guide grooves are provided on the bottom of each adjusting plate from the center outwards, with the bottom and top ends of the two guide grooves inclined towards the sides of the adjusting plate. Blocking members extend downwards from the outer edges of the two guide grooves on the bottom of the adjusting plate.

[0012] Preferably, guide rods are fixedly provided on the two clamping components around the axis of rotational connection with the planting rod. One end of the guide rod located inside the clamping component cavity is in the guide groove at the bottom of the adjusting plate, that is, the inner ends of the guide rods on the two clamping components are respectively in the two guide grooves on both sides of the bottom of the adjusting plate. One end of the guide rods on the two clamping components extending outward from the clamping component and extending a certain distance outward, and a tension spring is provided between the outer extension ends of the guide rods on the two clamping components. The two ends of the tension spring are fixedly connected to the corresponding guide rods on the two clamping components. Under the pulling action of the tension spring, the guide rods on both sides can be pulled together towards the middle, so that the two clamping components can be closed and merged under the action of the tension spring.

[0014] Preferably, the gripper includes a gripping rod and a hand-tightening bolt; the gripping rod has a hollow interior, and the hollow portion of the gripping rod is fitted onto the upper half of the planting rod, allowing the gripping rod to be raised and lowered on the upper half of the planting rod; the gripping rod has multiple holes arranged in a vertical trajectory, and the planting rod has a threaded hole corresponding to the vertical trajectory of the multiple holes, which matches the thread on the hand-tightening bolt; the hand-tightening bolt can be inserted into any of the holes and then threaded into the threaded hole on the planting rod; handles for the planting personnel to grip are fixedly provided on both sides of the top end of the gripping rod.

[0015] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0016] Firstly, by pressing down on the gripper, the seedling extractor at the bottom cuts the two ends of the stem node with the seedling on the sugarcane stalk, separating the stem node with the seedling from the entire sugarcane stalk. Then, by operating the drive mechanism, the seedling extractor clamps the cut stem node and removes the soil, leaving the clamped sugarcane seedling in the removed soil. The transplanting of sugarcane seedlings can be completed with only one person controlling the planter.

[0017] Secondly, the shell-like chamber inside the clamping component forms a closed space when retracted, which can completely wrap the sugarcane seedling roots and surrounding soil. Compared with the open structure of traditional shovel-type seedling pickers, this design can reduce soil scattering during transplanting, improve the contact area between the sugarcane seedling roots and the soil, and significantly shorten the seedling recovery period. Furthermore, the vertical flat surface of the clamping component on the opposite side fits closely with the sugarcane seedling stalk when clamping, which controls the tilt angle of the sugarcane seedling when it is clamped and makes it less likely to tip over significantly. This solves the problem of sugarcane seedling lodging caused by the curvature error of the clamping surface in traditional seedling pickers, and provides a foundation for upright growth for subsequent mechanized sprinkler irrigation and fertilization.

[0018] Thirdly, the spiked end design at the bottom of the gripping component makes the soil-breaking function faster, allowing the planter to insert the two gripping components into the soil without having to press the gripper forcefully. This is very labor-saving in operation. In addition, the handles on both sides of the top of the gripping rod allow the planter to control the planter with both hands at the same time to achieve a rapid downward operation, realizing the seedling cutting, soil insertion, transplanting, and planting operations in the process of sugarcane seedling transplanting.

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0037] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] This invention provides a sugarcane seedling transplanter, including a seedling taker 1;

[0039] See attached document Figures 1 to 4As shown, the top of the seedling picker 1 is provided with a gripper 2 for the grower to hold and operate; the seedling picker 1 and the gripper 2 are connected by a planting rod 3; the planting rod 3 is provided with a drive mechanism that can control the expansion of the seedling picker 1; the planting rod 3, the seedling picker 1 and the gripper 2 are arranged in a straight line.

[0040] Before using this patented technology, sugarcane stalks with seedlings should be placed in the transplanting area. The planter then uses a handheld controller 2 to move the entire planter. The seedling extractor 1 at the bottom of the controller 2 is aligned with the stem node with the seedling on the sugarcane stalk. Pressing down on the controller 2 causes the extractor 1 to cut the two ends of the stem node with the seedling from top to bottom, separating the stem node from the entire sugarcane stalk. The drive mechanism is then used to clamp the cut stem node. The entire planter is then moved to the designated planting area, and the controller 2 is pressed again to insert the extractor 1 into the soil. The process is repeated. The control drive mechanism causes the seedling picker 1 to open and push the soil to both sides. As the seedling picker 1 opens, the sugarcane stem section that is clamped inside will fall downwards due to gravity and remain in the pushed soil. Finally, the holder 2 is pulled upwards to remove the seedling picker 1 from the soil. This completes the cutting and transplanting of sugarcane seedlings from the sugarcane stalk. During operation, only one person needs to control and move the planter to complete the transplanting of sugarcane seedlings. At the same time, due to the linear arrangement of the planting stalk 3, the seedling picker 1 and the holder 2, the vertical movement trajectory of the seedling picker 1 is strictly consistent when pressing down or pulling up the holder 2, so that the sugarcane seedling can be successfully planted into the soil from top to bottom.

[0041] In a further preferred embodiment, refer to the appendix. Figure 4 As shown, the lower half of the planting rod 3 has a chamber inside, which extends from the bottom of the planting rod 3; the seedling extractor 1 includes two clamping parts 11, which are symmetrically arranged at the bottom of the planting rod 3. The tops of the two clamping parts 11 are rotatably connected to the bottom of the planting rod 3, so that the two clamping parts 11 can open to the sides or close to the middle at the bottom of the planting rod 3.

[0042] Each of the clamping components 11 is inclined from the middle to the bottom on both sides, forming a spiked end 12 at the bottom. The opposing sides of the two clamping components 11 are vertical, flat surfaces 13. Each clamping component 11 has a chamber for placing soil and sugarcane seedlings, which extends from the opposing sides of the two clamping components 11, forming a shell-like structure. The opposite sides of the two clamping components 11 are inclined, forming sharp, blade-like ends 14 on the opposite sides. Both sides of the planting rod 3 are sharp ends 14, matching the shape of the opposite sides of the two clamping components 11.

[0043] See attached document Figure 8 As shown, the seedling extractor 1, composed of two gripping components 11, can act like a cutter to cut off the sugarcane stem nodes and penetrate the soil. When the grower operates the drive mechanism to open the two gripping components 11 to both sides, the internal chambers of the two gripping components 11 are open. When the middle area of ​​the two gripping components 11 is aligned with the stem node with the seedling, as the two gripping components 11 move downwards, the sharp ends at the bottom of the two gripping components 11 will contact the surface of the sugarcane stalk and gradually penetrate into the sugarcane. When the holder 2 is pressed continuously, the bottom ends of the two gripping components 11 will continue to penetrate into the sugarcane. The opposite side of the two gripping components 11 is designed with sharp ends 14, so that the outer ends of the gripping components 11 can also penetrate into the sugarcane like a cutter, thereby allowing the gripping components 11 to be quickly inserted. Inside the sugarcane, when the bottom ends of the two gripping parts 11 emerge from under the sugarcane, the stem nodes with seedlings will be located in the middle chamber area of ​​the two gripping parts 11. Then, the drive mechanism can be controlled to control the two gripping parts 11 to retract towards the middle, and the flat areas 13 on the opposite sides of the two gripping parts 11 will fit together and protect the stem nodes with seedlings inside. At this time, the entire planter is moved to the planting area to be transplanted, and then the holder 2 is pressed down, so that the two gripping parts 11 in the closed state drill downward into the soil. The two gripping parts 11 are combined to form a wedge-shaped structure with spikes at the bottom. When the two gripping parts 11 come into contact with the soil surface, the soil can spread out in the surrounding direction with the spikes 12 of the two gripping parts 11. As the two gripping parts 11 continue to drill in, the squeezed soil area will have free space.

[0044] After the two clamping parts 11 are opened to the sides by the drive mechanism, the soil is pushed aside to the sides and above. Under the blocking effect of the two clamping parts 11, the pushed-apart soil will not fall back into the idle area, thus providing a planting area for the transplanting of sugarcane seedlings. As the two clamping parts 11 are opened, the stem nodes with seedlings inside will fall downwards due to gravity and fall into the idle space of the pushed-apart soil. Then, the drive mechanism is continuously controlled to maintain the open state of the two clamping parts 11 and the holder 2 is pulled upwards to pull the two clamping parts 11 out of the soil. As the two clamping parts 11 are pulled out of the soil, the pushed-apart soil will gradually gather and fall towards the middle along the sharp ends 14 on the outside of the two clamping parts 11 and backfill the pushed-apart restricted area to bury the stem nodes of the seedlings. After the transplanting operation is completed, artificial soil backfilling can also be carried out to ensure that the sugarcane seedlings can be completely covered by soil.

[0045] In actual operation, the depth of the two gripping parts 11 penetrating the soil can be adjusted according to the different needs of sugarcane seedling transplanting. If it is necessary to increase the penetration depth, the holder 2 should be pressed after the two gripping parts 11 have penetrated the soil, so that the lower half of the planting rod 3 also penetrates the soil. The two sides of the planting rod 3 are equipped with sharp ends 14, which allows the planting rod 3 to push the soil it contacts away from the soil, just like the two gripping parts 11, so that the two gripping parts 11 can penetrate deeper into the soil. When the entire planting device is then pulled out, it is necessary to start... The final control drive mechanism maintains the open state of the two clamping parts 11 to prevent the two clamping parts 11 from closing too early and cutting off the seedling part. Since the planting rod 3 is also drilled into the soil, the distance between the top layer of soil that has been pulled away from the ground and the stem node of the seedling is far. When the two clamping parts 11 are pulled out of the soil, the lower layer of soil that has been pulled away by the two clamping parts 11 will be backfilled into the idle area and cover the stem node of the seedling. The soil that has been squeezed and pulled away by the planting rod 3 will also collapse downward due to gravity and cover the stem node of the seedling, and initially fix the stem node.

[0046] Secondly, when the sugarcane seedlings are planted in a shallow layer of soil, the two clamping parts 11 are simply inserted into the soil. When the planter is subsequently removed, since the top layer of soil that has been removed is close to the stem node of the seedling, if the two clamping parts 11 in the open state are directly removed from the soil, the large obstruction range of the two clamping parts 11 will hinder the backfilling of the surrounding soil. Therefore, in order to avoid the seedling stem node being exposed outside the soil due to the inability of the soil that has been removed from the surface of the soil to be backfilled in time by gravity because of the instant removal of the two clamping parts 11, the drive mechanism can be slowly operated when the two clamping parts 11 are removed downwards, so that the two clamping parts 11 are slowly closed until the seedling has completely left the chamber area of ​​the two clamping parts 11, and then the two clamping parts 11 are completely closed.

[0047] In a further preferred embodiment, refer to the appendix. Figure 4 and 5 As shown, the driving mechanism includes an adjusting cylinder 4; the external shape of the adjusting cylinder 4 matches the internal cavity shape of the planting rod 3, and the adjusting cylinder 4 can be adjusted up and down within the cavity of the planting rod 3; support rods 41 are provided on both sides of the adjusting cylinder 4, and matching sliding grooves 31 are provided on the planting rod 3 corresponding to the support rods 41 on both sides of the adjusting cylinder 4. The sliding grooves 31 are arranged in a vertical trajectory on the planting rod 3, so that the support rods 41 on both sides of the adjusting cylinder 4 can move within the corresponding sliding grooves 31 as the adjusting cylinder 4 rises and falls; one end of the support rod 41 is fixedly connected to the adjusting cylinder 4, and the other end extends out from the corresponding sliding groove 31 and extends to the outer area of ​​the planting rod 3. A fixed part is provided on the extended end of the support rod 41 in the outer area of ​​the planting rod 3. A foot pedal 42 is provided for the planter to operate, allowing the planter to move the entire adjusting cylinder 4 downwards when stepping on the corresponding pedal 42. The adjusting cylinder 4 has an internal chamber, forming a shell-like structure that matches the shape of the planting rod 3. Adjusting plates 43 are provided on both the front and rear sides of the bottom of the adjusting cylinder 4, and the adjusting plates 43 on the front and rear sides of the adjusting cylinder 4 are positioned between the two clamping components 11. Guide grooves 44 are provided on the bottom of the adjusting plates 43 from the middle to both sides, and the bottom and top of the two guide grooves 44 are inclined towards the sides of the adjusting plates 43. Blocking members 45 are provided on the bottom of the adjusting plates 43 at the outer edges of the two guide grooves 44.

[0048] In a further preferred embodiment, refer to the appendix. Figure 4 , 6As shown in Figure 7, guide rods 46 are fixedly installed on the two clamping components 11 around the axis of rotational connection with the planting rod 3. One end of the guide rod 46 located inside the cavity of the clamping component 11 is in the guide groove 44 at the bottom of the adjusting plate 43, that is, the inner ends of the guide rods 46 on the two clamping components 11 are respectively in the two guide grooves 44 on both sides of the bottom of the adjusting plate 43. One end of the guide rods 46 on the two clamping components 11 extends outward from the clamping component 11 and extends a certain distance outward. A tension spring 47 is provided between the outer extension ends of the guide rods 46 on the two clamping components 11. The two ends of the tension spring 47 are fixedly connected to the corresponding guide rods 46 on the two clamping components 11. Under the pulling action of the tension spring 47, the guide rods 46 on both sides can be pulled together towards the middle, so that the two clamping components 11 can be closed and merged under the action of the tension spring 47.

[0049] When operating the drive mechanism, the planter can step down or press down on the pedal 42 on one side of the planting rod 3. The support rods 41 and pedal 42 on both sides of the adjusting cylinder 4 allow the planter to operate the device from any position on the left or right. The sliding grooves 31 on the planting rod 3 corresponding to the support rods 41 on both sides of the adjusting cylinder 4 can provide the support rods 41 with a space for lifting and lowering, while limiting the maximum vertical movement of the support rods 41 on both sides of the adjusting cylinder 4. This prevents the adjusting cylinder 4 from dislodging from the planting rod 3 due to overload during lifting and lowering, which could damage the entire planter.

[0050] Under normal conditions, the tension springs 47 on the outer guide rods 46 of the two clamping components 11 will pull the two clamping components 11 towards the middle under the pulling action, so that the two clamping components 11 come together to form a wedge structure, so that the two clamping components 11 can always be in a closed state to drill into the soil; when the adjusting cylinder 4 moves downward, the bottom part of the guide grooves 44 on both sides of the adjusting plate 43 will squeeze and drive the guide rods 46 on the left and right clamping components 11, and push the guide rods 46 on both sides to open to the sides, so that the corresponding two clamping components 11 open in an inclined state with their own rotational connection with the planting rod 3 as the axis, so that the outer side of the two clamping components 11 can perform a prying operation on the soil in contact with the sides and the upper area, so that the soil inside the prying is formed with a cross-section similar to a fan shape, so that the horizontal stem section with seedlings can be placed into the restricted space;

[0051] As the guide grooves 44 on both sides of the adjusting plate 43 drive the guide rod 46 to move, when the guide rod 46 moves to the top of the outer side of the adjusting plate 43, the blocking member 45 set on the outer edge of the adjusting plate 43 can block the continuous movement of the guide rod 46. This can prevent the clamping part 11 from being overloaded and prematurely detached from the soil due to the excessive range of movement of the guide rod 46, thereby affecting the sugarcane seedling transplanting work.

[0052] After the soil-opening operation is completed, the control pedal 42 can be released immediately. As the pedal 42 loses its downward pressure control force, the two clamping parts 11 also retract under the pulling action of the tension spring 47 on the outer guide rod 46, thus completing the cutting and transplanting operation of the sugarcane seedling. When the two clamping parts 11 retract, the inner guide rod 46 will squeeze the top guide grooves 44 on both sides of the adjusting plate 43, causing the adjusting plate 43 to gradually move upward along the inclined trajectory of the guide grooves 44 on both sides, thereby allowing the adjusting plate 43 and the adjusting cylinder 4 to move upward and return to the initial position, so that the adjusting cylinder 4 and the adjusting cylinder 4 can be pressed down again by pressing down the pedal 42.

[0053] In a further preferred embodiment, refer to the appendix. Figure 9 As shown, a pressure block 5 is provided in the cavity of the adjusting cylinder 4. The shape of the pressure block 5 matches the shape of the internal cavity of the adjusting cylinder 4, and the pressure block 5 can be raised and lowered within the cavity of the adjusting cylinder 4. A pressure rod 51 is vertically provided at the top of the pressure block 5, and the bottom end of the pressure rod 51 is fixedly connected to the pressure block 5. The top end of the pressure rod 51 extends upward from the inside of the adjusting cylinder 4 to the upper half of the planting rod 3. A through hole 32 is provided in the upper half of the planting rod 3 for the pressure rod 51 to be raised and lowered. One side of the planting rod 3... A through groove 33 is provided, which communicates with the internal through hole 32 and extends to the outer area of ​​the planting rod 3. A tension spring 47 is provided inside the through hole 32 of the planting rod 3. The two ends of the tension spring 47 are fixedly connected to the top of the through hole 32 of the planting rod 3 and the top of the pressure rod 51, respectively. Under the pulling action of the tension spring 47, the pressure rod 51 can be driven to move upward in the through hole 32. A hand lever 52 for the planting personnel to hold and operate is horizontally placed at the top of the pressure rod 51. The bottom end of the hand lever 52 is fixedly connected to the pressure rod 51.

[0054] After a sugarcane seedling transplant is completed, soil remains in the chambers of the two clamping parts 11. This soil will continue to move upwards during the transplant and remain in the chamber of the regulating cylinder 4. Therefore, the pressure block 5 installed in the chamber of the regulating cylinder 4 can seal the top of the chamber, preventing the soil from moving upwards. At the same time, after a sugarcane seedling transplant is completed, the pressure rod 51 can be lowered by pressing down the hand lever 52, which in turn lowers the pressure block 5 inside the regulating cylinder 4. This drives the soil remaining in the chamber of the regulating cylinder 4 downwards through the bottom end of the pressure block 5 until the remaining soil falls out of the chamber of the regulating cylinder 4 and exits through the two open clamping parts. The soil inside the regulating cylinder 4 falls down, thus completing the cleaning of the soil remaining in the chamber of the regulating cylinder 4. This prevents soil from remaining in the chamber of the regulating cylinder 4 and causing soil to press on the seedlings after the sugarcane seedlings are cut, which would affect the normal transplanting work. It can also further clean the inside of the regulating cylinder 4 to reduce the possibility of soil clumping due to water loss if it remains in the chamber of the regulating cylinder 4 for a long time, which would prevent the chamber of the regulating cylinder 4 from properly accommodating the sugarcane seedlings. After cleaning the soil remaining in the regulating cylinder 4, the hand lever 52 can be released naturally, so that the pressure rod 51 moves upward under the pulling action of the internal tension spring 47 and drives the pressure block 5 back to its original position in the chamber of the regulating cylinder 4.

[0055] In a further preferred embodiment, refer to the appendix. Figure 9 As shown, the gripper 2 includes a gripping rod 21 and a hand-tightening bolt 22. The gripping rod 21 has a hollow interior, and the hollow part of the gripping rod 21 is fitted onto the upper half of the planting rod 3, allowing the gripping rod 21 to be raised and lowered on the upper half of the planting rod 3. The gripping rod 21 has multiple holes 23 arranged in a vertical trajectory. The planting rod 3 has a threaded hole that matches the thread on the hand-tightening bolt 22, corresponding to the vertical trajectory of the multiple holes 23. The hand-tightening bolt 22 can be inserted into the threaded hole on the planting rod 3 by passing through any of the holes 23 and then threadedly engaging. Handles 24 for the planting personnel to grip are fixedly provided on both sides of the top of the gripping rod 21.

[0056] To facilitate control of the gripper 2 by the grower, the sleeve design of the gripping rod 21 and the planting rod 3 allows for adjustment of the telescopic length between them. After adjusting the telescopic length of the gripping rod 21 on the planting rod 3, the matching hand-tightening bolt 22 can be inserted into the corresponding hole 23, and the threaded end of the hand-tightening bolt 22 can be screwed into the threaded hole on the planting rod 3. This creates a movement limit between the hole 32, the hand-tightening bolt 22, the hole 23 of the gripping rod 21, and the threaded hole of the planting rod 3, so that the telescopic length of the gripping rod 21 on the planting rod 3 is adjusted and locked.

[0057] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
