Description

Technical Field

[0001] This invention relates to the field of jujube cultivation technology. Specifically, it relates to an ecological cultivation technique for jujube. Background Technology

[0002] Sour jujube is a traditional Chinese medicine, and due to its unique medicinal value, it has gained popularity among consumers in recent years. After cultivation, sour jujube seedlings need to be transplanted to the field. The traditional transplanting method involves manually digging planting holes, placing the seedlings in the holes, backfilling with soil, and compacting it. This method, because the soil is compacted from the surface downwards after backfilling, easily creates voids in the bottom soil, and oxygen cannot easily penetrate through the compacted surface soil to reach the roots, making it difficult to guarantee the survival rate of the seedlings. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is to provide a method for ecological cultivation of jujube trees that ensures the survival rate of transplanted jujube seedlings.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a method for ecological cultivation of jujube, comprising the following steps:

[0005] Step A: Select well-lit land, deep plow it, and apply organic fertilizer to the soil;

[0006] Step B: Use a double-layer drilling mechanism to drill a foundation hole on the ground, and use the double-layer drilling mechanism to drill a transplanting hole coaxially on the foundation hole. Drill a spiral groove on the hole wall of the transplanting hole, and the drilling of the transplanting hole will cause loose soil to fall into the bottom of the transplanting hole.

[0007] Step C: Place the jujube seedling in the rotating clamping mechanism to rotate the jujube seedling, and prune the jujube seedling through the pruning mechanism;

[0013] The aforementioned method for ecological cultivation of jujube includes a rotary clamping mechanism comprising a first rotary gear ring, a transmission chain, and a drive wheel. Both the drive wheel and the first rotary gear ring are rotatably mounted on a sliding plate.

[0016] The technical solution of the present invention achieves the following beneficial technical effects:

[0017] 1. This invention, through the cooperation of a double-layer drilling mechanism and a soil compaction mechanism, ensures that after the seedling is transplanted into the transplanting hole, the backfill soil is compacted layer by layer, guaranteeing full contact between the seedling and the soil, forming a stable support effect for the seedling, and the soil compaction is uniform, which can avoid root suffocation caused by the surface soil being too compacted and preventing oxygen from penetrating.

[0018] 2. This invention, by setting up a double-layer drilling mechanism, can first drill a foundation hole on the ground surface. During drilling, whether manually or mechanically excavated, the soil around the hole is compressed due to the excavation force, making it more compact and reducing oxygen flow. However, this invention, by setting up an outer drill sleeve for secondary hole enlargement, avoids this problem. Since there is no support inside the hole, the soil collapses directly inwards to the bottom during enlargement, reducing the compression of the surrounding soil and allowing the enlarged soil to... The soil falls inward to the bottom of the hole. Secondly, spiral grooves are made on the hole wall by the tip of the pressure plate, which increases the surface area of ​​the hole wall, increases the oxygen passage area, and increases the bonding area with the backfill soil after transplanting, thus increasing the stability of the seedling. The soil from the hole wall falls into the bottom of the hole, and its perimeter is higher than the middle, forming a depression that can conform to the shape of the seedling's root ball, improving the contact effect with the roots. At the same time, the fertility and oxygen content of the surface soil are higher than that of the lower soil, transferring the surface soil to the lower layer, further ensuring the survival rate of transplanting.

[0019] 3. This invention, by setting up a soil compaction mechanism, can compact the backfill soil layer by layer when rotating, achieving uniform compaction of the backfill soil in the transplanting hole. This allows oxygen to penetrate and improves the support effect on the tree roots, avoiding the root suffocation damage caused by traditional transplanting methods and preventing voids in the backfill soil. Secondly, by setting up a pressure roller with an impact effect, a compacted layer with equal intervals can be formed between the root ball and the transplanting hole, improving the stability of the seedling. Furthermore, the compaction of the compacted layer gradually decreases from deep to shallow, further reducing the impact on oxygen penetration. Attached Figure Description

Detailed Implementation

[0031] This embodiment of the jujube ecological cultivation technique includes the following steps:

[0032] Step A: Select well-lit land, deep plow it, and apply organic fertilizer to the soil;

[0033] Step B: Using the double-layer drilling mechanism 6, a foundation hole 11 is drilled in the ground, and a transplanting hole 12 is coaxially drilled on the foundation hole 11 through the double-layer drilling mechanism 6. A spiral groove 13 is drilled on the hole wall of the transplanting hole 12. The loose expanded soil 14 generated by drilling the transplanting hole 12 falls into the bottom of the transplanting hole 12. The spiral groove 13 is drilled on the hole wall by the tip of the pressure plate 609, which increases the surface area of ​​the hole wall, increases the oxygen passage area, and increases the bonding area with the backfill soil after transplanting, thus increasing the stability of the seedling. The expanded soil 14 falls from the hole wall to the bottom of the hole, and its periphery is higher than the middle, forming a depression that can conform to the shape of the seedling's soil ball, improving the contact effect with the roots. At the same time, the fertility and oxygen content of the surface soil are higher than that of the lower soil, transferring the surface soil to the lower layer, further ensuring the survival rate of transplanting.

[0034] Step C: Place the jujube seedling in the rotating clamping mechanism 7 to rotate the jujube seedling, and prune the jujube seedling through the pruning mechanism 8;

[0035] Step D: Move the rotating clamping mechanism 7 to place the jujube seedling into the transplanting hole 12;

[0036] Step E: Fill the space between the transplanting hole 12 and the roots of the jujube seedling with backfill soil 15 layer by layer. At the same time, turn on the soil compaction mechanism 9 to compact the backfill soil 15 layer by layer. By setting up the soil compaction mechanism 9, the backfill soil 15 can be compacted layer by layer when it rotates, so as to achieve uniform compaction of the backfill soil 15 in the transplanting hole 12. This allows oxygen to penetrate and improves the support effect on the tree roots, avoiding the root suffocation damage caused by traditional transplanting methods and preventing voids in the backfill soil.

[0037] like Figure 3As shown, the double-layer drilling mechanism 6 includes an outer drill sleeve 601, an inner drill core 604, a threaded tube 602, and a screw 603. The inner drill core 604 is installed inside the outer drill sleeve 601. A guide groove 605 is formed along the axial direction on the inner side wall of the outer drill sleeve 601. A guide block 606 is fixedly installed on the side wall of the inner drill core 604. The guide block 606 is slidably installed in the guide groove 605. The threaded tube 602 is coaxially installed inside the outer drill sleeve 601. One end of the screw 603 is coaxially fixedly connected to the end of the inner drill core 604. The other end is threaded into the threaded tube 602, the end of the threaded tube 602 protrudes from the top of the outer drill sleeve 601, and the outside of the threaded tube 602 is rotatably connected to the outer drill sleeve 601 via a bearing; a sliding hole 607 is provided axially in the inner side wall of the outer drill sleeve 601, and a movable groove 612 is provided radially in the inner side wall of the outer drill sleeve 601; one end of the sliding hole 607 communicates with one end of the movable groove 612, and the other end of the movable groove 612 penetrates the inner side wall of the outer drill sleeve 601; a push rod 608 is slidably installed in the sliding hole 607. One end of the push rod 608 extends through the bottom end of the outer drill sleeve 601, and a push block 610 is fixedly installed on the other end of the push rod 608. A first spring 611 is installed between the push block 610 and the bottom of the sliding hole 607. A locking block 613 is slidably installed in the movable groove 612. A locking groove 614 is opened on the side wall of the threaded tube 602. One end of the locking block 613 abuts against the side wall of the push block 610, and the other end of the locking block 613 is inserted into the locking block 614 to restrict the relative rotation of the threaded tube 602 and the outer drill sleeve 601. The locking block 613 and the movable groove A second spring 615 is installed between the groove walls of 612; a pressure plate 609 is hinged to the bottom end of the outer drill sleeve 601, and one end of the top rod 608 protrudes from the outer drill sleeve 601 and abuts against the pressure plate 609. The pressure plate 609 is inclined relative to the cross section of the outer drill sleeve 601. By setting up a double-layer drilling mechanism 6, a foundation hole 11 can be opened on the ground surface first, and a secondary hole enlargement operation can be carried out by setting up the outer drill sleeve 601. Since there is no support inside the hole, the soil collapses directly to the inside and falls into the bottom of the hole during hole enlargement, reducing the compression of the surrounding soil.

[0038] like Figure 1-2 As shown, a telescopic transmission mechanism 5 is connected to one end of the threaded pipe 602 that protrudes from the outer drill sleeve 601. The top end of the telescopic transmission mechanism 5 is rotatably mounted on the sliding plate 3. The sliding plate 3 is slidably mounted on the upper support plate 2. A sliding groove is provided on the upper support plate 2, and the sliding plate 3 fits into the sliding groove. A lower support plate 1 is fixedly mounted on the lower support plate 2 through a support frame. The soil compaction mechanism 9 is rotatably mounted on the lower support plate 1. A first motor 4 is mounted on the top of the sliding plate 3. The power output shaft of the first motor 4 is connected to the telescopic transmission mechanism 5. A rotating clamping mechanism 7 is mounted on the sliding plate 3 and is connected to the first motor 4.

[0039] like Figure 5As shown, the lower support plate 1 has a circular hole 101 and an opening groove 102. The circular hole 101 is located in the middle of the lower support plate 1, one end of the opening groove 102 is connected to the circular hole 101, and the other end of the opening groove 102 extends out of the end of the lower support plate 1; Figure 4 As shown, the soil compaction mechanism 9 includes a second rotary gear ring 901, a base plate 902, a load-bearing rod 904, and a pressure roller 906. The second rotary gear ring 901 is rotatably installed in the circular hole 101, and an opening is provided on one side of the second rotary gear ring 901. The base plate 902 is fixedly installed on the second rotary gear ring 901, and an adjusting plate 903 is slidably installed on the base plate 902. The adjusting plate 903 slides along the diameter direction of the second rotary gear ring 901. The load-bearing rod 904 is slidably installed through the adjusting plate 903 and is arranged along the axial direction of the second rotary gear ring 901. A bracket 905 is fixedly installed on the bottom end of the load-bearing rod 904, and a pressure roller 906 is rotatably installed on the bracket 905. A rectangular hole is provided at the top end of the load-bearing rod 904, and a sliding rod 912 is slidably installed in the rectangular hole. The sliding rod 912 extends... A weight 907 is fixedly installed on one end of the rectangular hole. The edge of the weight 907 protrudes from the edge of the sliding rod 912. A support rod 908 is fixedly installed on the adjusting plate 903. A load-bearing wheel 909 is rotatably installed on the top and bottom of the side wall of the support rod 908. The two load-bearing wheels 909 are connected by a load-bearing chain 910. A support block 911 is fixedly installed on the side wall of the load-bearing chain 910. The support block 911 is located below the edge of the weight 907. A second motor is driven and connected to one of the load-bearing wheels 909. The second motor is installed on the lower support plate 1. By setting a pressure roller 906 with an impact effect, a compacted layer 16 with equal intervals can be formed between the root ball and the transplanting hole 12, which improves the stability of the seedling. Furthermore, the compaction of the compacted layer 16 gradually decreases from deep to shallow, further reducing the impact on oxygen permeability.

[0040] like Figure 6 As shown, the rotary clamping mechanism 7 includes a first rotary gear ring 701, a transmission chain 702, and a drive wheel 709. Both the drive wheel 709 and the first rotary gear ring 701 are rotatably mounted on the sliding plate 3. The drive wheel 709 has an opening that passes through the sliding plate 3. The drive wheel 709 is coaxially fixedly mounted on the power output shaft of the first motor 4. Guide wheels 703 are rotatably mounted on both sides of the first rotary gear ring 701 on the sliding plate 3. The transmission chain 702 is drivenly connected to the drive wheel 709. The inner side of the transmission chain 702 overlaps with the two guide wheels 703, and the outer side of the transmission chain 702 is drivenly connected to the first rotary gear ring 701. Bases 705 are installed on both sides of the inner wall of the first rotary gear ring 701. Adjusting rods 706 are installed on the bases 705. A fixing plate 707 is fixedly connected to the end of the adjusting rod 706. A clamping plate 708 is slidably mounted on the fixing plate 707.

[0041] like Figure 7As shown, the trimming mechanism 8 includes a mounting plate 801 and a connecting plate 804. The mounting plate 801 is slidably mounted on the sliding plate 3, and the connecting plate 804 is fixedly mounted on the mounting plate 801. Rollers 802 are rotatably mounted on both ends of the connecting plate 804. A chainsaw 803 is connected to the two rollers 802. One roller 802 is driven to rotate by a third motor.

[0042] like Figure 1 As shown, the telescopic transmission mechanism 5 includes a transmission pipe 501 and a transmission shaft 502. The transmission shaft 502 passes through the transmission pipe 501, and the end of the transmission shaft 502 is fixedly connected to the end of the threaded pipe 602. The end of the transmission pipe 501 is connected to the first motor 4. A valve 10 is installed on the side wall of the transmission pipe 501. A pull rope is connected to the valve 10. The other end of the pull rope is connected to the double-layer drilling mechanism 6. The water outlet end of the valve 10 is located above the double-layer drilling mechanism 6.

[0043] Workflow: In the actual transplanting operation, first move the entire device to the corresponding position, and then connect the power supply to the corresponding motor;

[0044] Align the double-layer drilling mechanism 6 with the circular hole 101. The double-layer drilling mechanism 6 is initially in the following state: Figure 3 As shown, the jujube seedling is then placed between two clamping plates 708, so that the root ball of the jujube seedling contacts the lower support plate 1. Then, the two adjusting rods 706 are adjusted. The adjusting rods 706 are either manual screws or cylinders. In this embodiment, manual screws are used. When the manual screws are rotated, they unscrew from the base 705 and push the fixing plates 707 closer to each other. The end of the manual screws is rotatably connected to the fixing plates 707, so that the two fixing plates push the clamping plates 708 to clamp the main trunk of the seedling.

[0045] like Figure 3As shown, after the double-layer drilling mechanism 6 is aligned with the circular hole 101, the telescopic transmission mechanism 5 can freely extend and retract. Due to its own weight, the double-layer drilling mechanism 6 presses down, causing the inner drill core 604 to press against the soil surface. The first motor 4 is started, and the first motor 4 drives the double-layer drilling mechanism 6 to rotate through the telescopic transmission mechanism 5. Drill teeth are installed on the end of the inner drill core 604 to facilitate hole opening. In the initial state, under the action of the locking block 613, the outer drill sleeve 601 and the threaded pipe 602 are relatively fixed, that is, they cannot rotate relative to each other. The transmission shaft 502 transmits power to the threaded pipe 602. The threaded pipe 602 drives the outer drill sleeve 601 to rotate through the locking block 613. The outer drill sleeve 601 rotates through the guide block 6. The cooperation of 06 and guide groove 605 drives the inner drill core 604 to rotate, drilling a hole. When the inner drill core 604 is completely drilled into the soil, a foundation hole 11 is formed in the soil. At this time, the pressure plate 609 contacts the ground surface and presses on the ground surface. The pressure plate 609 rotates along its hinge and pushes the top rod 608 and the top block 610 upward. After the top block 610 moves, the locking block 613 loses its clamping force. Under the action of the second spring 615, the locking block 613 moves and disengages from the locking groove 614. When the threaded tube 602 continues to rotate, it cannot transmit power to the outer drill sleeve 601 through the locking block 613. The outer drill sleeve 601 remains stable under the action of friction with the ground surface. When the threaded tube 602 rotates, it is in contact with the ground surface. With the screw 603 engaged, the inner drill core 604 retracts into the outer drill sleeve 601 until it is completely retracted. Then, the top of the inner drill core 604 presses against the end of the threaded tube 602. Because the screw 603 and the threaded tube 602 are mutually engaged and locked, rotation can be transmitted. The threaded tube 602 transmits power to the screw 603, which drives the inner drill core 604 to rotate. The inner drill core 604, through the engagement of the guide groove 605 and the guide block 606, drives the outer drill sleeve 601 to rotate. After the outer drill sleeve 601 rotates, two inclined pressure plates 609 are used to drill and enlarge the area around the foundation hole 11, forming the transplant hole 12. During the hole enlargement operation, loose enlarged soil 14 falls into the bottom of the transplanting hole 12, and the surrounding area of ​​the accumulated enlarged soil 14 is higher than the middle, forming a central depression that can fit the bottom of the root ball. The surface soil has slightly higher fertility and oxygen content than the soil in the stratum. During the hole enlargement operation, the surface soil can fall into the bottom of the foundation hole 11 first, which is conducive to the survival and growth of the seedling. Because the pressure plate 609 is set at an angle and the double-layer drilling mechanism 6 uses its own weight to drill, during the drilling process, the tip of the pressure plate 609 protruding from the outer drill sleeve 601 can cut a spiral groove 13 on the side wall of the transplanting hole 12, which is conducive to the combination of the backfill soil 15 with the surrounding soil and improves the aeration.

[0046] After the transplanting hole 12 is opened, as the transplanting hole 12 moves down a preset distance, the pull rope pulls the valve 10 to open. The water inlet of the valve 10 is connected to the water source through a rotary joint to prevent the water pipe from getting tangled. After the valve 10 is opened, the water source is poured into the transplanting hole 12 through the pipeline to moisten the enlarged hole soil 14.

[0047] As the first motor 4 rotates, Figure 6 As shown, the first rotary gear ring 701 can be driven to rotate through the transmission chain 702, which in turn drives the sapling to rotate. Since the first rotary gear ring 701 is relatively large, the transmission has a deceleration effect, that is, the rotation speed of the first rotary gear ring 701 is slower than that of the first motor 4. When the pruning mechanism 8 is started, the lateral branches of the sapling are pruned by the chainsaw 803 of the pruning mechanism 8 to reduce the transpiration of the sapling and ensure the survival rate. After the pruning is completed, the pruning mechanism 8 is turned off. At the same time, while the sapling is rotating, the rotation can be used to scrape the soil ball at the bottom of the sapling against the opening groove 102 on the lower support plate 1, scraping off the compacted soil layer at the bottom.

[0048] Turn off the first motor 4, lift the double-layer drilling mechanism 6 upwards, and then push the sliding plate 3 to move the sapling to the round hole 101. Under the action of gravity, the clamping plate 708 slides downwards, and the sapling falls into the transplanting hole 12. The clamping plate 708 can also prevent the sapling from tilting. Figure 4 As shown, then move the adjusting plate 903 so that the pressure roller 906 is positioned within the transplanting hole 12 and can compact the backfill soil. Start the motors driving the second rotary gear ring 901 and the load-bearing wheel 909. The motors are not shown in the figure. The specific driving structure of the second rotary gear ring 901 is as follows. Figure 6 As shown, to avoid interrupting power transmission at the opening of the second rotating toothed ring 901, the rotation of the second rotating toothed ring 901 drives the pressure roller 906 to roll the soil, making the soil compact and ensuring complete contact with the roots of the seedling. Then, backfill soil 15 is manually and evenly spread in the circumferential direction into the transplanting hole 12, compacting it layer by layer to ensure uniform compaction and facilitate root respiration. At the same time, the rotation of the load-bearing chain 910 drives the support block 911 to move. When it contacts the weight block 907, it lifts it upward. After the support block 911 detaches from the weight block 907, the weight block... 907 falls freely, impacting the load-bearing rod 904, causing the pressure roller 906 to compact the backfill soil 15, forming a compacted layer 16. This compacted layer 16 is then evenly spaced around the sapling's root ball, improving the sapling's stability. As the amount of backfill soil increases, the pressure roller 906 gradually moves upward, causing the load-bearing rod 904 to lift the weight 907 upward. Since the support block 911 moves to a constant height, when the weight 907 is at a higher position, its automatic landing distance decreases, reducing the impact force and thus decreasing the compaction of the compacted layer 16. Figure 10 As shown, this creates a gradually decreasing density from deep to shallow, ensuring both support for the seedlings and allowing oxygen to penetrate downwards, thus preventing root suffocation.
