Description

Technical Field

[0001] This invention relates to the technical field of fruit tree planting, and in particular to an agricultural fruit tree seedling planting device. Background Technology

[0002] Planting fruit tree seedlings requires digging a pit in the planting area, then placing the seedling with its root ball into the pit, backfilling, and watering. When digging the pit, to facilitate water retention during subsequent watering, some of the excavated soil needs to be broken up and piled into a ring around the pit, and then the soil needs to be compacted to form a dam around the seedling.

[0003] In traditional planting methods, the digging of pits can be done manually or mechanically, but the construction of embankments can only be done manually. This not only consumes a lot of manpower, but also seriously affects planting efficiency. Summary of the Invention

A plurality of pushing ridges are provided between the top of the cone and the bottom of the groove, distributed along the circumference of the outer cylinder. The pushing ridges are inclined on the horizontal plane and fixed on the cone.

[0008] Furthermore, the planting device also includes a power unit for providing power to the drilling structure. The power unit includes a threaded rod coaxially fixed inside the outer cylinder and a plurality of power rods circumferentially distributed around the threaded rod. The length direction of the power rods is parallel to the axis of the outer cylinder. An insertion hole is provided at the middle position of the top of the cone. The bottom of the threaded rod and the bottom of the power rod are both inserted into the insertion hole. A slider is provided between two adjacent power rods. One side of the slider is fixed to the inner wall of the insertion hole, and the other side of the slider is provided with a thread. The thread cooperates with the threaded rod.

[0016] 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.

Therefore, they should not be construed as limitations on this invention.

[0018] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0019] like Figures 1 to 8 As shown, an agricultural fruit tree seedling planting device of the present invention includes an outer cylinder 1, a shaped ring 2 located inside the outer cylinder 1, and a drilling structure 3. The outer cylinder 1 has an opening facing downwards. The shaped ring 2 slides inside the outer cylinder 1 along the axial direction of the outer cylinder 1, and the shaped ring 2 and the inner wall of the outer cylinder 1 form a groove-shaped structure with the opening facing downwards. The groove-shaped structure is annular around the axial direction of the outer cylinder 1. The shaped ring 2 is rotatably connected to the drilling structure 3, and the drilling structure 3 is used to drill into the soil. In this invention, the outer cylinder 1 can be placed on the ground and used to block the dust generated when the drilling structure 3 excavates the soil, thereby effectively reducing environmental pollution. At the same time, the outer cylinder 1 can contain the soil excavated by the drilling structure 3 to prevent the soil from scattering randomly. The ring 2 is annular in shape with an obtuse angle in cross-section. One side of the obtuse angle is located at the top and is horizontal, while the other side of the obtuse angle is inclined and located inside the ring 2. With the help of the inner wall of the outer cylinder 1, the obtuse angle shape can be transformed into an arc shape, and the opening of the arc shape faces downward. Overall, the ring 2 and the inner wall of the outer cylinder 1 form an annular groove structure, which is used to compress and shape the soil excavated by the drilling structure 3. The outer cylinder 1 can be installed on agricultural machinery or other vehicles for easy movement. In use, the outer cylinder 1 is first placed on the ground of the planting area, and then the drilling structure 3 is used to break the soil and excavate. The drilling structure 3 lifts the broken soil upward and transports it to the ground around the drilling structure 3. That is, the broken and lifted soil is located below the shaped ring 2. As the drilling structure 3 drills into the ground, the shaped ring 2 moves downward in sync. The soil near the inner wall of the outer cylinder 1 below the shaped ring 2 gradually increases. When the shaped ring 2 contacts the soil and squeezes it, the soil is compacted. The trough structure formed by the outer cylinder 1 and the shaped ring 2 can shape the soil to form a ring-shaped cofferdam with water-blocking function. At this time, the drilling depth of the drilling structure 3 reaches the specified requirement. Then the outer cylinder 1 is lifted, and the shaped ring 2 and the drilling structure 3 are stationary. The shaped ring 2 maintains the state of pressing the soil to prevent the outer cylinder 1 from carrying the soil upward. When the shaped ring 2 separates from the outer cylinder 1, the shaped ring 2 and the drilling structure 3 can be lifted. At this time, a pit will be formed in the planting area, and a cofferdam will exist around the pit. By gathering the soil excavated by the drilling structure 3 and compressing and shaping it with the help of the molding ring 2, a water-blocking dike can be formed during the excavation process. This avoids the time wasted in building the dike separately, improves work efficiency, and avoids the manpower loss of manually breaking up the soil and building the dike, thus improving the degree of automation.

[0020] Furthermore, the drilling structure 3 includes a cone 4, a support column 5, and a spiral plate 6. The support column 5 is installed at the bottom of the cone 4, and the spiral plate 6 is arranged around the cone 4 and the support column 5. The spiral plate 6 is in the shape of an inverted cone; The cone 4 and the support column 5 can support the spiral plate 6. The conical design of the spiral plate 6 can facilitate its drilling into the ground and breaking the soil, thereby reducing the difficulty of soil excavation. The cone 4 can push the soil away from the axis of the cone 4 when the spiral plate 6 is conveying soil upward, so that the soil gathers towards the inner wall of the outer cylinder 1, reducing the amount of soil temporarily stored on the drilling structure 3, thereby reducing the weight of the drilling structure 3 and making it easier to remove the excavated soil.

[0021] Furthermore, the spiral plate 6 includes a spiral section 7 located on the support column 5, a spiral section 8 located on the cone 4, and a transition section 9 connecting the spiral section 7 and the spiral section 8. The cross section of the spiral section 7 is inclined upward, and the cross section of the spiral section 8 is inclined downward. Because the cross-section of the first spiral section 7 is inclined upwards, the angle between the upper surface of the first spiral section 7 and the axis of the drilling structure 3 is an acute angle. This facilitates soil collection and transportation, preventing soil from being unable to be lifted and discharged from the pit by the drilling structure 3 due to its proximity to the inner wall of the pit. The downward-inclined cross-section of the second spiral section 8 makes the angle between the upper surface of the second spiral section 8 and the axis of the drilling structure 3 an obtuse angle. This allows the soil on the upper surface of the second spiral section 8 to naturally disperse in all directions, preventing soil from accumulating on the second spiral section 8. The structure of the first spiral section 7 and the second spiral section 8 can achieve the purpose of soil collection, lifting, and dispersion during excavation. The transition section 9 is mainly used to connect the first spiral section 7 and the second spiral section 8, facilitating the transfer of soil from the first spiral section 7 to the second spiral section 8.

[0022] Furthermore, a connecting part is provided between the shaped ring 2 and the drilling structure 3. The connecting part includes a first groove 10 provided in the inner ring of the shaped ring 2, a second groove 11 provided in the top of the cone 4, and a bearing 12 installed between the first groove 10 and the second groove 11. A plurality of pushing ribs 13 are provided between the top of the cone 4 and the bottom of the groove 10, which are distributed along the circumference of the outer cylinder 1. The pushing ribs 13 are inclined on the horizontal plane and are fixed on the cone 4. like Figure 6 As shown, the first groove 10 and the second groove 11 are used to fix the outer ring and inner ring of the bearing 12, respectively, thereby enabling the bearing 12 to achieve a rotatable connection between the ring 2 and the drilling structure 3. During excavation, due to the gap between the first groove 10 and the cone 4, soil can easily enter the bearing 12 through the gap. To avoid this phenomenon, the present invention adopts a structure of several pushing ridges 13. When the cone 4 rotates, the pushing ridges 13 move synchronously. The soil that has entered the gap between the first groove 10 and the cone 4 will be pushed outward by the centrifugal force of the pushing ridges 13, thereby achieving a dynamic sealing effect on the gap. The inclined setting of the pushing ridges 13 can more effectively block the soil and improve the sealing effect.

[0023] Furthermore, the planting device also includes a power unit for providing power to the drilling structure 3. The power unit includes a threaded rod 14 coaxially fixed inside the outer cylinder 1 and a plurality of power rods 15 circumferentially distributed around the threaded rod 14. The length direction of the power rods 15 is parallel to the axis of the outer cylinder 1. The cone 4 has an insertion hole at the middle of its top. The bottom of the threaded rod 14 and the bottom of the power rod 15 are both inserted into the insertion hole. A slider 16 is provided between two adjacent power rods 15. One side of the slider 16 is fixed to the inner wall of the insertion hole, and the other side of the slider 16 is provided with a thread. The thread cooperates with the threaded rod 14. A power wheel 17 is provided at the top of several power rods 15. The power wheel 17 is rotatably installed inside the outer cylinder 1. The power wheel 17 can support one end of several power rods 15, and several sliders 16 can support the middle of several power wheels 17. When the power wheel 17 rotates, it will drive several power rods 15 and several sliders 16 to rotate synchronously. Several sliders 16 drive the drilling structure 3 to rotate synchronously. Since the sliders 16 are threadedly connected to the threaded rods 14, the sliders 16 move synchronously in the vertical direction. The sliders 16 drive the drilling structure 3 to move in the vertical direction, thereby realizing the rotary drilling operation of the drilling structure 3. The sliders 16 slide relative to the power rods 15.

[0024] Furthermore, an auxiliary wheel 18 is rotatably disposed on the outer wall of the drive wheel 17, and the drive wheel 17 and the auxiliary wheel 18 are connected by a torsion spring 19; A motor 20 is fixed on the inner wall of the outer cylinder 1. A transmission wheel 21 is provided at the output end of the motor 20. The transmission wheel 21 is connected to the auxiliary wheel 18 in a transmission manner. like Figure 8As shown, the motor 20 provides rotational power to the drive wheel 17 via the transmission wheel 21, auxiliary wheel 18, and torsion spring 19, thereby providing power to the drilling structure 3 via several power rods 15. When the drilling structure 3 excavates areas with high soil hardness, to avoid damage to the motor 20 caused by the instantaneous decrease in the rotational speed of the drive wheel 17, this invention employs a buffer structure consisting of the auxiliary wheel 18 and the torsion spring 19. When the rotational speed of the drive wheel 17 drops instantaneously, the drive wheel 17 and the auxiliary wheel 18 generate relative motion. At this time, the torsion spring 19 undergoes elastic deformation, thus providing a buffering and protective effect for the motor 20. When the drive wheel 17 completes the excavation of the area, the elastic force of the torsion spring 19 is released, accelerating the rotational speed of the drive wheel 17 until the torsion spring 19 stabilizes in its natural state. By utilizing the above-mentioned buffer structure, the impact of the rotational speed fluctuations of the drilling structure 3 during excavation on the motor 20 can be effectively reduced, improving the operational stability of the equipment.

[0025] Furthermore, the auxiliary wheel 18 is provided with a voltage regulating unit, which is used to adjust the voltage of the motor 20 when the torsion spring 19 undergoes elastic deformation; When the torsion spring 19 undergoes elastic deformation, the drilling structure 3 becomes more difficult to excavate. At this time, the voltage of the motor 20 can be adjusted by the voltage regulating unit to regulate the speed and torque output of the motor 20, ensuring that the drilling structure 3 has sufficient power to excavate the soil and avoiding equipment shutdown due to insufficient power.

[0026] Furthermore, the voltage regulating unit includes an arc-shaped resistance plate 22 fixed relative to the power wheel 17. The arc-shaped resistance plate 22 is coaxial with the auxiliary wheel 18. A plurality of conductive rollers 23 are rolled on the outer wall of the arc-shaped resistance plate 22. The conductive rollers 23 are rotatably mounted on the auxiliary wheel 18. The external power supply provides power to the motor 20 through the arc-shaped resistor plate 22 and several conductive rollers 23; like Figure 8 As shown, several conductive rollers 23 are arranged in an arc shape and all contact the arc-shaped resistor plate 22. This can realize a multi-point connection between the arc-shaped resistor plate 22 and the conductive rollers 23, improve the current transmission effect, and avoid the current transmission speed being limited due to the small contact area when a single conductive roller 23 is used with the arc-shaped resistor plate 22. The arc-shaped resistor plate 22 and the drive wheel 17 can be connected by a fixed plate, connecting frame or other structure to support and fix the arc-shaped resistor plate 22. When the torsion spring 19 undergoes elastic deformation, the power wheel 17 and the auxiliary wheel 18 rotate relative to each other. At this time, a number of conductive rollers 23 move relative to the arc-shaped resistance plate 22, that is, the conductive rollers 23 roll on the arc-shaped resistance plate 22, and the length of the arc-shaped resistance plate 22 connected to the circuit changes, thereby adjusting the voltage ratio of the arc-shaped resistance plate 22 in the circuit, which facilitates the adjustment of the voltage of the motor 20. Since the output torque of the motor 20 has a limit value, in order to avoid damage to the motor 20, a contact switch 24 is provided at one end of the arc-shaped resistor plate 22. The connection position of the torsion spring 19 and the auxiliary wheel 18 can be used in conjunction with the contact switch 24. When the rotation angle of the auxiliary wheel 18 relative to the power wheel 17 is too large, the connection position of the auxiliary wheel 18 and the torsion spring 19 will abut against the contact switch 24. At this time, the contact switch 24 can control the motor 20 to stop rotating.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
