Description

Technical Field

[0001] This invention belongs to the field of agricultural seedling planting technology, and in particular relates to a chestnut seedling planting device that facilitates transplanting. Background Technology

[0002] Chestnuts belong to the genus Castanea of ​​the family Fagaceae. They are an economic plant rich in nutrients such as starch, monosaccharides and disaccharides, carotene, thiamine, riboflavin, nicotinic acid, ascorbic acid, protein, fat, and inorganic salts. They can be eaten raw or cooked, and can also be processed into flavored foods such as chestnut chicken canned food, chestnut soup, chocolate, milk substitute, and chestnut preserves, as well as fillings for various pastries.

[0003] Chestnut seedlings are deep-rooted trees with well-developed lateral roots and dense fibrous roots. Traditional transplanting methods mostly rely on manual digging with shovels, which has many drawbacks:

[0004] 1. Manual digging makes it difficult to form a complete soil ball, which easily leads to the breakage of lateral roots and the loss of fibrous roots, seriously affecting the survival rate of transplanted seedlings;

[0005] 2. When encountering rocks or hard roots during excavation, it is difficult to detect resistance in time, which can easily damage tools or break the root ball. The entire process relies on manual operation, resulting in low efficiency in positioning, excavation, and transplanting, making it difficult to meet the needs of large-scale planting.

[0006] 3. Apart from transplanting from the soil to another location, when transplanting seedlings from another location to the soil, the soil ball of the seedling is prone to tipping over due to the shift in the center of gravity during the transplanting process, which can further damage the root system. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a chestnut seedling planting device that facilitates transplantation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A chestnut seedling planting device for easy transplanting includes a base plate. Universal wheels and a push-pull handle are fixed to the bottom and top of the base plate, respectively. A first vertically oriented lead screw slide is fixed to one side of the outer wall of the base plate. A second horizontally oriented lead screw slide is fixedly connected to the side wall of the slider on the first lead screw slide. A vertical plate is fixed to the slider on the second lead screw slide. An extension plate is fixed to one side of the outer wall of the vertical plate. A limiting groove is formed through the extension plate. A connecting plate slides inside the limiting groove. A power shaft rotates inside the connecting plate via a bearing. A first motor is fixed to one side of the outer wall of the connecting plate, and the output end of the first motor is fixedly connected to one end of the power shaft. A transplanting mechanism is fixed to the other end of the power shaft. A detection mechanism is fixed inside the extension plate to detect whether the entire transplanting mechanism shifts during the transplanting process. The detection mechanism determines whether the transplanting mechanism encounters resistance during transplanting, causing the entire transplanting mechanism to shift. A protective mechanism is fixed to one side of the outer wall of the vertical plate to prevent the seedling from tipping over during transplanting.

[0010] Preferably, the detection mechanism includes an arc-shaped buckle, a limiting slide plate, an abutment plate, a fixing plate, a first switch, and a trigger head. Two arc-shaped buckles are provided, and each buckle is rotatably connected to the inner wall of the extension plate via a rotating shaft. The arc-shaped surface of each buckle abuts against the arc-shaped plate of the connecting plate via a pre-tightened elastic element. Slide grooves for the limiting slide plate to slide are provided on both sides of the inner wall of the extension plate. One side of the outer wall of the abutment plate is fixedly connected to one side of the outer wall of the limiting slide plate, and the other side of the outer wall of the abutment plate abuts against the arc-shaped surface of the connecting plate. The fixing plate is fixedly connected to both sides of the inner wall of the extension plate. The first switch is fixedly connected to one side of the outer wall of the fixing plate. A return spring is fixedly provided between the fixing plate and the limiting slide plate. The trigger head is fixedly connected to one side of the outer wall of the limiting slide plate, and the trigger head and the first switch are horizontally opposite each other.

[0011] Preferably, the transplanting mechanism includes a pot planting assembly for planting and a transplanting assembly for transplanting seedlings. The pot planting assembly includes a left pot, a right pot, and a connecting plate. The left pot and the right pot are detachably connected. The connecting plate is fixedly connected to one of the pots and is also fixedly connected to a drive shaft.

[0012] Preferably, the transplanting assembly includes a transplanting circular frame, multiple retractable soil-breaking ruler assemblies for accelerating cutting and breaking during the transplanting process, and a second motor. The transplanting circular frame is fixedly connected to the top of one of the pots and detachably connected to the other pot, with the connection points sealed. The retractable soil-breaking ruler assemblies are evenly arranged along the inner circumference of the transplanting circular frame, and the second motor is fixedly connected to the inner wall of the transplanting circular frame.

[0013] Preferably, the telescopic breaking ruler assembly includes a fixed cylinder, a roller, a telescopic rod, a third motor, a tapered rod, and a breaking ruler. The fixed cylinder is fixedly connected to the inner wall of the transplanting circular frame. The roller is rotatably connected to one side wall of the fixed cylinder via a bearing. The telescopic rod is threadedly connected to the inner wall of the roller, and the inner wall of the fixed cylinder has a sliding groove for the telescopic rod to slide. The top of the telescopic rod is fixedly connected to the third motor, and the output end of the third motor is fixedly connected to the tapered rod. Multiple breaking rulers are provided and evenly arranged along the circumferential direction of the tapered rod surface. A gear is fixedly provided at the output end of the third motor, and a gear is fixedly provided on the outer wall of the roller. The multiple gears are connected by a rack and pinion chain transmission.

[0014] Preferably, the protective mechanism includes a third lead screw slide, a side plate, an adjusting plate, a positioning plate, and an abutment baffle. The side plate is fixedly connected to one side of the outer wall of the vertical plate. The side plate has a sliding groove for the third lead screw slide to slide, and a pre-tightening spring connected to the third lead screw slide is provided inside the sliding groove. The adjusting plate is fixedly connected to the slider on the third lead screw slide. The positioning plate is fixedly connected to one side of the outer wall of the adjusting plate. The abutment baffle is slidably connected to the inside of the positioning plate by a spring and extends out of the inside of the positioning plate. The bottom of the abutment baffle abuts against the inner wall of the combined basin.

[0015] The present invention has the following beneficial effects:

[0016] 1. Regarding the sticky adhering substances on the surface of construction waste, this application achieves efficient removal through a pre-treatment mechanism for sticky substances. It adopts a vertically placed plate and uses an adjustment component to tilt the plate, allowing the hammering component to fully hammer different parts of the plate. The sticky adhering substances are more easily removed under the combined action of hammering force and gravity, effectively avoiding interference from sticky adhering substances in subsequent processes, providing a clean material basis for subsequent crushing and sorting, and ensuring the smoothness of the overall processing flow.

[0017] 2. The crushed material is conveyed to the spreading mechanism via the second conveyor belt. The spreading mechanism evenly disperses the material, avoiding material stacking. This allows all types of metal particles to be fully exposed during the subsequent metal sorting process, creating favorable conditions for the precise separation of magnetic and non-magnetic metals and significantly improving the comprehensiveness and accuracy of the sorting.

[0018] 3. The magnetic metal removal mechanism moves synchronously with the spreading mechanism, enabling synchronous and full-coverage magnetic adsorption of the spread material. This effectively avoids missed magnetic metals and improves the removal efficiency. Simultaneously, the cleaning component promptly removes the magnetic metals adsorbed on the magnetic adsorption plate, and the timing component allows for timed control of the cleaning action. This prevents magnetic metals from accumulating on the adsorption plate surface, which could reduce adsorption force, ensuring the continuous and efficient operation of the magnetic adsorption plate and extending the equipment's lifespan.

[0019] 4. After magnetic separation, the material smoothly enters the eddy current separator via a level conveyor belt. Utilizing the difference in repulsive force generated by different non-magnetic metals in an alternating magnetic field, the non-magnetic metals are graded and separated, allowing different types of non-magnetic metals to fall into their corresponding storage boxes. This not only achieves effective separation of non-magnetic metals from impurities such as concrete aggregates, but also completes the graded recycling of non-magnetic metals, improving their recycling value and ensuring the purity of recycled materials such as concrete aggregates.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Example 1: Refer to Figure 1 - Figure 8The device includes a base plate 1, with casters and a push-pull handle fixed to its bottom and top, respectively. The casters are rubber casters with brakes to secure the device during transplantation and prevent displacement during digging. The push-pull handle has an anti-slip rubber sleeve on its outer wall for easy gripping and force application. A first lead screw slide 2 is vertically mounted on one side of the outer wall of the base plate 1. A second lead screw slide 3 is horizontally mounted and fixedly connected to the side wall of the slider on the first lead screw slide 2. Both the first and second lead screw slides are ball screw slides, and their drive ends are equipped with servo motors to achieve precise lifting and lateral movement of the transplanting mechanism 10. Dust covers are provided on the outer sides of the lead screw slides to prevent soil and dust from entering the lead screw gaps and affecting sliding accuracy. A vertical plate 4 is fixed to the slider on the second lead screw slide 3. The vertical plate 4 is bolted to the slider, and anti-slip pads are provided at the connection point to enhance connection stability. An extension plate 5 is fixedly installed on one side of the outer wall of the vertical plate 4. A limiting groove is provided through the extension plate 5, and a connecting plate 6 is slidably installed inside the limiting groove. Both the inner wall of the limiting groove and the outer wall of the connecting plate 6 are polished, and the inner wall of the limiting groove is provided with a guide protrusion. The outer wall of the connecting plate 6 is provided with a corresponding guide groove. The guide protrusion and the guide groove slide together to prevent the connecting plate 6 from shifting or getting stuck during sliding, ensuring that the connecting plate 6 slides only in a straight line along the limiting groove. A power shaft 7 is rotatably installed inside the connecting plate 6 via a bearing, and a first motor 8 is fixedly installed on one side of the outer wall of the connecting plate 6. The output end of the first motor 8 is fixedly connected to one end of the power shaft 7, and a transplanting mechanism 10 is fixedly installed at the other end of the power shaft 7. A detection mechanism 9 is fixedly installed inside the extension plate 5 to detect whether the entire transplanting mechanism 10 has shifted during the transplanting process. The detection mechanism 9 determines whether the transplanting mechanism 10 has encountered resistance during the transplanting process, causing the entire transplanting mechanism 10 to shift.

[0032] The detection mechanism 9 includes an arc-shaped buckle 91, a limiting slide plate 92, an abutment plate 93, a fixing plate 94, a first switch 95, and a trigger head 96. Two arc-shaped buckles 91 are provided, and each buckle 91 is rotatably connected to the inner wall of the extension plate 5 via a rotating shaft. The two arc-shaped buckles 91 are symmetrically arranged on both sides of the connecting plate 6, with their arc-shaped surfaces fitting snugly against the arc-shaped plate of the connecting plate 6. The arc-shaped surfaces of the arc-shaped buckles 91 abut against the arc-shaped plate of the connecting plate 6 via a pre-tightening elastic element. The pre-tightening elastic element is a torsion spring, with its two ends fixedly connected to the arc-shaped buckle 91 and the inner wall of the extension plate 5, respectively. The pre-tightening force of the torsion spring can be adjusted to adapt to the resistance detection threshold under different soil hardness, avoiding false triggering of the detection signal by soft soil resistance. Slide grooves for the limiting slide plate 92 are provided on both sides of the inner wall of the extension plate 5. The outer wall of the abutment plate 93... The side of the limiting slide plate 92 is fixedly connected to one side of the outer wall of the side plate 93, and the other side of the outer wall of the abutting plate 93 is abutted against the arc-shaped surface of the connecting plate 6. The fixing plate 94 is fixedly connected to both sides of the inner wall of the extension plate 5. The first switch 95 is fixedly connected to one side of the outer wall of the fixing plate 94. A return spring is fixedly provided between the fixing plate 94 and the limiting slide plate 92. The return spring is a compression spring, and its two ends are welded and fixed to the fixing plate 94 and the limiting slide plate 92 respectively, to ensure that the limiting slide plate 92 can quickly reset after the obstruction is released, thereby driving the trigger head 96 to separate from the first switch 95 and restoring the detection mechanism 9 to the ready-to-trigger state. The trigger head 96 is fixedly connected to one side of the outer wall of the limiting slide plate 92, and the trigger head 96 and the first switch 95 are horizontally opposite each other. The first switch 95 is a micro switch, and its output end is electrically connected to the control terminal through a wire, which can transmit the obstruction signal in real time.

[0033] The transplanting mechanism 10 includes a pot planting assembly 101 for planting and a transplanting assembly 102 for transplanting seedlings. The pot planting assembly 101 includes a left pot 1011, a right pot 1012, and a connecting plate 1013. The left pot 1011 and the right pot 1012 are detachably connected. Specifically, each of the joints between the left pot 1011 and the right pot 1012 is provided with a connecting lug, and a bolt hole is provided through the connecting lug. The detachable connection is achieved by bolts passing through the bolt holes, and a sealing strip is provided at the joint. To prevent soil from entering the basin during excavation, the bottom of both the left basin 1011 and the right basin 1012 are provided with sharp cutting edges made of hard alloy material to enhance cutting strength and facilitate cutting into the soil. The connecting plate 1013 is fixedly connected to one of the basins and is also fixedly connected to the power shaft 7. The connecting plate 1013 is welded to the basin and locked to the power shaft 7 by a key connection and bolts to ensure that the power shaft 7 can stably drive the basin to rotate.

[0034] The transplanting assembly 102 includes a transplanting circular frame 1021, multiple retractable soil-breaking ruler assemblies 103 for accelerating cutting and breaking during transplanting, and a second motor 1022. The transplanting circular frame 1021 is fixedly connected to the top of one of the pots and detachably connected to the other pot, with all connections sealed. The retractable soil-breaking ruler assemblies 103 are evenly arranged along the inner circumference of the transplanting circular frame 1021, and the second motor 1022 is fixedly connected to the inner wall of the transplanting circular frame 1021.

[0035] The telescopic soil-breaking ruler assembly 103 includes a fixed cylinder 1031, a roller 1032, a telescopic rod 1033, a third motor 1034, a tapered rod 1035, and a breaking ruler 1036. The fixed cylinder 1031 is fixedly connected to the inner wall of the transplanting circular frame 1021. The roller 1032 is rotatably connected to one side wall of the fixed cylinder 1031 via a bearing. The telescopic rod 1033 is threadedly connected to the inner wall of the roller 1032, and the inner wall of the fixed cylinder 1031 has a sliding groove for the telescopic rod 1033 to slide. The top of the telescopic rod 1033 is fixedly connected to the third motor 1034, and the output end of the third motor 1034 is fixedly connected to the tapered rod 1035. Multiple breaking rulers 1036 are provided and evenly arranged along the circumferential direction of the tapered rod 1035. A gear is fixedly provided at the output end of the third motor 1034, and a gear is fixedly provided on the outer wall of the roller 1032. The multiple gears are connected by a rack and pinion chain transmission.

[0036] In this embodiment:

[0037] The operator pushes and pulls the lever to move the device, and the casters move the entire device to the target transplanting area. The operator then activates the brake mechanism on the casters to secure the device and prevent movement during subsequent operations. The status of each component is checked: the pre-tightening elastic element of the arc-shaped buckle 91 is confirmed to be in a normal pre-tightening state, the return spring is free from jamming and deformation, the telescopic soil-breaking ruler assembly 103 is retracted into the fixed cylinder 1031, and the abutment baffle 115 of the protective mechanism 11 is reset to its initial position (in this embodiment, the protective mechanism 11 is not included; only that all moving parts are free from jamming is ensured). The power is turned on, and the power units such as the lead screw slide and motor enter standby mode. The trigger head 96 of the detection mechanism 9 maintains a preset distance from the first switch 95 and is in a ready-to-trigger state.

[0038] The device is pushed to the transplanting area, and the first screw slide 2 and the second screw slide 3 are controlled by the control terminal to adjust the position of the transplanting mechanism 10 so that the bottom of the pot is in contact with the soil surface and the cut edge of the bottom of the pot is in full contact with the soil.

[0039] The first motor 8 is started, and the power shaft 7 drives the transplanting mechanism 10 to rotate under the drive of the first motor 8. The sharp edge of the bottom of the pot cuts the soil and gradually cuts into the soil as it rotates. The left pot 1011 and the right pot 1012 are fastened together to form a complete pot, which completely wraps the soil ball of the seedling. If it encounters a stone or hard root system, the pot will not be able to continue rotating after hitting the obstacle. The torque of the transmission chain increases suddenly. The torque is greater than the pre-tightening force of the pre-tightening elastic element of the arc-shaped buckle 91. This causes the connecting plate 6 to break through the limiting pressure of the arc-shaped buckle 91 and slide in a straight line along the limiting groove. When the connecting plate 6 slides, it squeezes the abutment plate 93 and causes the abutment plate 93 to move synchronously. The abutment plate 93 pushes the limiting slide plate 92 to slide along the slide groove, compressing the reset spring until the trigger head 96 touches the first switch 95. The first switch 95 sends an obstruction signal to the control terminal. The control terminal immediately controls the first motor 8 to stop rotating and triggers the overload protection mechanism.

[0040] Upon receiving an obstruction signal, the second motor 1022 inside the transplanting frame 1021 starts. The output of the second motor 1022 drives the gear fixedly connected to it to rotate, which in turn drives multiple rollers 1032 to rotate synchronously via rack and pinion transmission. Since the telescopic rod 1033 is threadedly connected to the inner wall of the roller 1032 and is limited by the groove of the fixed cylinder 1031, the rotation of the roller 1032 drives the telescopic rod 1033 to extend along the groove of the fixed cylinder 1031 until the crushing ruler 1036 approaches the obstacle. Then, the third motor 1034 starts, which drives the conical rod 1035 to rotate, causing the crushing ruler 1036 to rotate at high speed and perform directional crushing of the obstacle. After crushing, the second motor 1022 is reversed, causing the drum 1032 to reverse as well, retracting the telescopic rod 1033 back into the fixed cylinder 1031. Then, the first motor 8 resumes operation, driving the pot to continue rotating and continuing the excavation. If the resistance is not eliminated after crushing, the control terminal triggers an avoidance logic, controlling the first lead screw slide 2 to slightly lift the transplanting mechanism 10 away from the soil surface. Then, the second lead screw slide 3 is controlled to shift laterally to avoid the obstacle. Afterward, the first lead screw slide 2 drives the transplanting mechanism 10 downward, causing the pot to re-enter the soil for cutting. If an obstruction signal is triggered again, the above crushing-avoidance process is repeated until the resistance is eliminated, completing the soil ball excavation.

[0041] Example 2:

[0042] Reference Figure 1 - Figure 9 The difference from Embodiment 1 is that a protective mechanism 11 for preventing seedlings from tipping over is fixedly provided on one side of the outer wall of the vertical plate 4.

[0043] The protective mechanism 11 includes a third lead screw slide 111, a side plate 112, an adjusting plate 113, a positioning plate 114, and an abutment baffle 115. The side plate 112 is fixedly connected to one side of the outer wall of the vertical plate 4. The side plate 112 has a sliding groove for the third lead screw slide 111 to slide, and a pre-tightening spring connected to the third lead screw slide 111 is provided inside the sliding groove. The adjusting plate 113 is fixedly connected to the slider on the third lead screw slide 111. The positioning plate 114 is fixedly connected to one side of the outer wall of the adjusting plate 113. The abutment baffle 115 is slidably connected to the inside of the positioning plate 114 by a spring and extends out of the inside of the positioning plate 114. The bottom of the abutment baffle 115 abuts against the inner wall of the combined basin.

[0044] In this embodiment: Seedling transplantation: Dual-mode selectable operation

[0045] Mode 1: Disassembling and transplanting from pots (preferably high-value seedlings)

[0046] After digging, the control terminal controls the second screw slide 3 to move the transplanting mechanism 10 above the planting hole. Then, the first screw slide 2 is controlled to adjust the height, aligning the pot with the planting hole to ensure the root ball falls smoothly into the hole. The connecting bolts between the left pot 1011 and the right pot 1012 are unlocked and removed, separating them. The intact root ball falls into the planting hole with the seedling, avoiding any disturbance to the roots and maximizing root protection. After the operator covers and compacts the soil, the left pot 1011 and right pot 1012 are re-fastened and locked through the bolt holes in the connecting lugs, returning to the initial state, ready for the next operation.

[0047] Mode 2: Directly pour out and transplant (preferred for large-scale operations)

[0048] After digging, the control terminal moves the transplanting mechanism 10 above the planting hole and activates the third screw slide 111 of the protective mechanism 11. The slider of the third screw slide 111 drives the adjusting plate 113 and the positioning plate 114 to move synchronously, adjusting the horizontal position of the positioning plate 114 so that the abutment baffle 115 always elastically abuts against the inner wall of the pot, and the abutment baffle 115 is located on one side of the seedling. Assuming the pot is tilted to the left, the abutment baffle 115 will be located on the left side of the seedling, closely fitting the soil ball of the seedling. The control motor 8 is started, driving the power shaft 7 to rotate slowly, which in turn causes the pot to tilt slowly. During the tilting process, the seedling tends to tip over under the action of gravity. The abutment baffle 115, through the elastic force of the spring, always fits against the soil ball, dynamically adjusting its posture according to the tilt angle of the pot. The spring buffers and counteracts the tipping force of the seedling, preventing the seedling from tipping over.

[0049] During the rotation of the pot, the contact baffle 115 abuts against the inner wall of the pot, which pushes the third screw slide 111 to move synchronously along the groove on the side plate 112. The pre-tightening spring inside the groove is compressed, providing relative compressive force to ensure that the contact baffle 115 always has sufficient contact force. At the same time, the contact baffle 115 always abuts against the inner wall of the pot through the spring, which can accommodate soil balls of different sizes, keeping the seedlings in an upright position and avoiding root damage from traction.

[0050] After the soil ball slides smoothly into the planting hole, the first motor 8 is reversed to drive the pot back to the correct position. At the same time, the third lead screw slide 111 drives the abutment baffle 115 to reset, the spring returns to its initial state, and the pot returns to its initial position, ready for the transplanting of the next seedling.

[0051] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
