Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, specifically to a fruit tree planting hole-digging device. Background Technology

[0002] Fruit tree planting is an important part of agricultural economy and forestry production. Through scientific planting and subsequent management, multiple benefits such as fruit production, ecological greening and economic income can be achieved. In the process of large-scale fruit tree planting, the specifications of the planting pit, soil structure, aeration and water and fertilizer supply conditions are directly related to the root development of fruit trees, the speed of seedling establishment and the survival rate in the later stage.

[0003] In fruit tree planting, digging holes is a crucial step affecting planting efficiency and the later growth of fruit trees. Traditional fruit tree planting often uses manual digging or single-drill digging equipment. This method is not only labor-intensive and inefficient, making it difficult to meet the digging needs of large-scale fruit tree planting, but also results in planting holes with a single structure, poor soil aeration, and slow water infiltration and diffusion. This can easily lead to problems such as root hypoxia and waterlogging after planting, directly affecting the survival rate and early growth of fruit trees. In addition, conventional digging equipment tends to scatter the excavated soil, making the soil around the hole messy and increasing the workload of subsequent covering and cleaning. Some equipment is also limited in function and cannot simultaneously complete the integrated operation of digging, auxiliary soil covering, and watering, making it difficult to meet the high-efficiency and precise requirements of modern fruit tree planting.

[0004] Therefore, it is necessary to invent a fruit tree planting hole-digging device to solve the above problems. Summary of the Invention

A guide rod is symmetrically fixedly connected to one side of the receiving box, and the guide rod is movably connected through the guide plate.

[0016] Furthermore, a water tank is provided at one end of the top of the vehicle body, and a water outlet is provided at the bottom of the water tank. A valve is provided at the bottom of the vehicle body below the water tank, and a drain pipe is fixedly connected to the bottom of the valve.

[0020] Beneficial effects

[0021] The present invention has the following beneficial effects:

[0022] 1. Through the coordinated action of the drive shaft, main gear, driven gear, driven shaft, and two sets of spiral blades, the main pit and auxiliary pit are excavated synchronously. At the same time, the soil cut by the two sets of spiral blades is collected and piled up in a unified manner using a collection box, a third electric push rod, and a first push plate. This effectively solves the problems of high labor intensity and low operation efficiency of traditional manual pit digging or single-drill pit digging equipment, as well as the problems of poor soil permeability, slow water infiltration, easy root rot due to lack of oxygen in the fruit tree roots caused by the single planting pit structure, and the large amount of subsequent soil covering and preparation work caused by scattered and messy soil. It achieves the goals of reducing labor intensity, improving the efficiency of large-scale planting operations, improving the root growth environment of fruit trees, and increasing the survival rate of fruit trees.

[0023] 2. The first electric push rod of the lifting assembly precisely controls the soil penetration depth of the digging assembly. Combined with the limiting and supporting functions of the first and second limit blocks and the support block for the drive shaft and driven shaft, and the coordinated action of the tail plate, the fourth electric push rod, and the second push plate, precise soil backfilling is achieved. This effectively solves the problems of traditional digging equipment having limited functionality, being unable to simultaneously complete integrated operations such as digging and auxiliary soil preparation, and having inconsistent pit sizes that are difficult to adapt to the high-efficiency and refined needs of modern fruit tree planting. It achieves integrated operations of digging, collecting, and backfilling, adapting to the needs of large-scale and refined fruit tree planting, and improving operational continuity and practicality.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0042] Please see Figures 1-9 This invention provides a technical solution: a fruit tree planting hole-digging device, including a vehicle body 1. The vehicle body 1 serves as the load-bearing and mobility foundation of the entire device, enabling flexible transportation of the device within the planting site and providing stable support for continuous operations such as hole digging, soil covering, and watering. One end of the vehicle body 1 is equipped with a digging component 2, which mainly undertakes hole digging and shaping. The digging component 2 includes a support block 201 fixedly connected to the vehicle body 1. The support block 201 is used to provide central support and positioning, ensuring that the shaft does not undergo radial displacement during rotation. A drive shaft 202 is movably passed through the support block 201. The drive shaft 202 serves as the main power transmission shaft, used to transmit the torque of the driving device downward to the spiral blades. A main gear 204 is fixedly installed above the outer periphery of the drive shaft 202, which is used to achieve power distribution.

[0043] A first helical blade 205 is provided below the outer peripheral surface of the drive shaft 202. During rotation, the first helical blade 205 can cut the soil and transport it upward, thereby excavating the main pit for planting fruit trees in the ground and providing sufficient planting space and loose soil environment for the main pit.

[0044] The main gear 204 is meshed with the driven gear 206, achieving synchronous power transmission through gear meshing and preventing pit deformation caused by speed differences between the two shafts. The driven gear 206 is fixedly connected to the driven shaft 207, which drives the second helical blade 209 to rotate synchronously, achieving synchronous excavation of the auxiliary pit. The driven shaft 207 is movably connected to the support block 201, which limits and reduces wear on the driven shaft 207, improving the rotational stability of the shaft. The second helical blade 209 is located below the outer circumferential surface of the driven shaft 207, and the second helical blade 209 is used to drive the second helical blade 209 to rotate synchronously. An auxiliary pit is excavated simultaneously on one side of the main pit. The height of the second helical blade 209 is the same as that of the first helical blade 205, which ensures that the depths of the main pit and the auxiliary pit are consistent. The second helical blade 209 is located on one side of the first helical blade 205. The pitch of the first helical blade 205 and the helical lead of the second helical blade 209 are in a multiple relationship and are adapted to the transmission ratio of the main gear 204 and the driven gear 206. Through the adaptation and coordination of the blade parameters and the gear transmission ratio, the two sets of helical blades can achieve coordinated and stable operation, avoiding the jamming caused by the mismatch between the rotation speed and the pushing rhythm.

[0045] The first helical blade 205 rotates to form a main pit for planting, and the second helical blade 209 rotates to form an auxiliary pit for assisting the growth of fruit trees. The auxiliary pit is located on one side of the main pit, so that outside air can be transmitted from the side to the roots of the fruit trees in the main pit. At the same time, water can be quickly injected into the roots of the fruit trees through the auxiliary pit, thereby improving the survival rate of the fruit trees. The drive shaft 202 is movably connected to the first limiting block 203, which is used to limit the axial movement of the drive shaft 202, reduce the swaying amplitude during rotation, and improve the verticality of digging the pit. The bottom end of the first limiting block 203 is connected to the top end of the support block 201. The driven shaft 207 is movably connected to the second limiting block 208, which is used to position the driven shaft 207 from the top to prevent the shaft from swaying when the blade rotates. The bottom end of the second limiting block 208 is connected to the top side of the support block 201.

[0046] A lifting assembly 3 is installed on the top of the excavation assembly 2. The lifting assembly 3 is used to control the overall up and down movement of the excavation assembly 2, realizing the adjustment of the soil penetration depth and the repositioning of the drill after excavation. The lifting assembly 3 includes a support plate 301 symmetrically arranged on the top of one end of the vehicle body 1. The support plate 301 provides a stable mounting base for the electric push rods. The bottom end of each support plate 301 is provided with a first electric push rod 302. The first electric push rod 302 provides power for the lifting action, realizing precise control of the excavation depth. The telescopic ends of the two first electric push rods 302 are fixedly connected to a connecting plate 303, which is used for synchronous connection. The push rods on both sides ensure smooth lifting without tilting. A first vertical plate 304 is set in the middle of the top of the connecting plate 303. The first vertical plate 304 is used to fix the motor, so that the motor and the drive shaft 202 are arranged coaxially. A drive motor 305 is fixedly installed on one side of the first vertical plate 304. The drive motor 305 provides continuous power for the rotation of the spiral blade. The output end of the drive motor 305 is fixedly connected to the top of the drive shaft 202. A positioning plate 306 is fixedly connected to one side of the bottom of the connecting plate 303. The positioning plate 306 is used to support and position the upper end of the driven shaft 207, further improving the stability of the dual-axis operation.

[0047] A material stacking assembly 4 is installed at one end of the bottom of the vehicle body 1. The material stacking assembly 4 is used to collect the soil brought out during the excavation process, preventing the soil from scattering and affecting the working environment, and facilitating subsequent backfilling. The material stacking assembly 4 includes a base plate 401 fixed at one end of the bottom of the vehicle body 1. A second electric push rod 402 is fixedly installed in the middle of the bottom of the base plate 401. The second electric push rod 402 is used to push the receiving box 404 closer to or away from the ground. Guide plates 403 are symmetrically arranged on both sides of the bottom of the base plate 401. The guide plates 403 cooperate with the guide rod 4040 to ensure that the moving path of the receiving box 404 is straight and unobstructed. The telescopic end of the second electric push rod 402 is fixedly connected to the receiving box 404. The receiving box 404 is used to temporarily collect the soil conveyed by the spiral blades, realizing centralized storage. One side of the receiving box 404 has an arc-shaped groove 405 adapted to the size of the first spiral blade 205 and the second spiral blade 209. The arc-shaped groove 405 can avoid the spiral blades and prevent the movement of dry soil. To improve soil collection efficiency, support wheels can be fitted to both ends of the bottom plate 401. A third electric push rod 406 is provided on one side of the receiving box 404. The third electric push rod 406 is used to push the first push plate 407 to push out and backfill the soil in the box. The first push plate 407 is slidably connected to the rectangular groove inside the receiving box 404. The collected soil is pushed out in an orderly manner by the movement of the push plate, which facilitates quick backfilling into the planting pit. A limit rod 408 is provided on the other side of the receiving box 404. The limit rod 408 is used to guide and limit the movement of the first push plate 407 to prevent the push plate from tilting and jamming. One end of the limit rod 408 is fixedly connected to the side of the receiving box 404, and the other end of the limit rod 408 is movable through the first push plate 407. A guide rod 4040 is symmetrically fixedly connected to one side of the receiving box 404. The guide rod 4040 is movable through the guide plate 403, so that the receiving box 404 remains stable during the extension and retraction process, improving the reliability of stacking and unloading.

[0048] A water tank 6 is installed at one end of the top of the vehicle body 1. The water tank 6 is used to store water for planting and to replenish water immediately after digging the pit. A water outlet 601 is opened at the bottom of the water tank 6 to discharge water stably. A valve 602 is installed at the bottom of the vehicle body 1 below the water tank 6. The valve 602 is used to control the water flow and release water as needed. A drain pipe 603 is fixedly connected to the bottom of the valve 602. The drain pipe 603 accurately leads water to the auxiliary pit and the main pit, accelerating the water penetration to the roots of the fruit trees.

[0049] A generator 5 is fixedly installed on the top of the vehicle body 1 near the water tank 6. The generator 5 provides power support for all electric actuators and control components on the equipment, ensuring the endurance of field operations. A second vertical plate 7 is fixedly installed on the other end of the top of the water tank 6. The second vertical plate 7 is used to install the controller 701 and the handle 702 to improve the convenience of operation. The controller 701 is used to centrally control the start and stop of each component and the sequence of actions to realize automated collaborative operation. The handle 702 is convenient for the operator to push and steer. The controller 701 is connected to the drive motor 305, the first electric push rod 302, the second electric push rod 402, the third electric push rod 406 and the generator 5 by wires.

[0050] It should be noted that the controller 701, drive motor 305, first electric push rod 302, second electric push rod 402, third electric push rod 406, and generator 5 are all existing devices, and the specific control logic is all existing technology, which will not be described in detail here.

[0051] A tail plate 8 is fixedly installed in the middle of one side of the vehicle body 1. The tail plate 8 provides installation support for the rear bulldozing structure. A fourth electric push rod 9 is set in the middle of the bottom of the tail plate 8. The fourth electric push rod 9 is used to drive the second push plate 11 to complete the soil preparation and compaction at the edge of the pit. One side of the second push plate 11 is arc-shaped. The arc-shaped structure can fit the shape of the pit, making the backfill soil more regular. The fourth electric push rod 9 is connected to the controller 701 by wire. The bottom two sides of the tail plate 8 are symmetrically fixedly connected to the third limit blocks 10. The third limit blocks 10 are used to guide and limit the lifting and lowering of the second push plate 11 to ensure stable operation. The two third limit blocks 10 are movably connected to the connecting block 1101. The bottom of the connecting block 1101 is fixedly connected to the top two sides of the second push plate 11.

[0052] It should be noted that the fourth electric actuator 9 is an existing device, and the specific control logic is all existing technology, which will not be described in detail here.

[0053] Working principle of the invention:

[0054] First, the operator pushes the vehicle body 1 to the designated planting position by gripping lever 702, starts generator 5 to provide power to all electric components of the equipment, and then controls the material stacking assembly 4 to start by controlling controller 701, controls the extension of the second electric push rod 402 to push the material collection box 404 downward until the bottom of the material collection box 404 is in contact with the ground, completing the positioning of the material collection assembly and preparing for subsequent soil collection. At this time, the limit rod 408 is in the initial state and plays a limiting role on the first push plate 407.

[0055] After the receiving assembly is in place, the controller 701 starts the lifting assembly 3 and the digging assembly 2 to work together, controlling the first electric push rod 302 to extend, pushing the connecting plate 303 to drive the drive motor 305, drive shaft 202, driven shaft 207 and two sets of spiral blades to move downwards synchronously until the first spiral blade 205 and the second spiral blade 209 contact the ground. At the same time, the drive motor 305 is started, and the output torque of the drive motor 305 is transmitted to the drive shaft 202, causing the drive shaft 202 to rotate. The drive shaft 202 drives the first spiral blade 205 on the outer periphery to rotate at high speed, cutting the soil and conveying the soil upwards. Inside the receiving box 404, on the other hand, through the meshing transmission of the main gear 204 and the driven gear 206 on the outer periphery, the driven shaft 207 is driven to rotate synchronously. The driven shaft 207 drives the second spiral blade 209 to rotate synchronously, cutting the soil synchronously on one side of the first spiral blade 205, and conveying the soil to the receiving box 404. During this process, the first limiting block 203 and the second limiting block 208 respectively limit the drive shaft 202 and the driven shaft 207 to prevent the shaft from moving or swaying. Finally, through the synchronous operation of the two sets of spiral blades, the main pit for planting fruit trees and the auxiliary pit for ventilation and water diversion are formed respectively.

[0056] After the excavation is completed, the controller 701 controls the first electric push rod 302 to retract, driving the excavation assembly 2 to return to its original position and detach from the pit. At the same time, the drive motor 305 is turned off, stopping the excavation and soil conveying. Then, the controller controls the third electric push rod 406 to extend, pushing the first push plate 407 to slide along the rectangular groove inside the receiving box 404. Under the guidance and limiting action of the limiting rod 408, the soil collected in the receiving box 404 is pushed out in an orderly manner and piled on one side of the main pit for subsequent backfilling. After the pushing is completed, the third electric push rod 406 retracts, driving the first push plate 407 to return to its original position. At the same time, the second electric push rod 402 retracts, driving the receiving box 404 to return to its original position, completing the soil collection and stacking.

[0057] During the backfilling operation, the operator moves the vehicle body 1 by gripping lever 702, aligning the second push plate 11 under the tailboard 8 with the soil piled on one side of the main pit and the perimeter of the main and auxiliary pits. The fourth electric push rod 9 is activated by controller 701, extending and pushing the second push plate 11 downward. Under the guiding and limiting action of the third limit block 10 and connecting block 1101, the arc surface of the second push plate 11 conforms to the shape of the pit. The operator pushes the vehicle body 1 slowly, driving the second push plate 11 to push the piled soil into the main and auxiliary pits, completing the backfilling operation. After the backfilling is completed, the fourth electric push rod 9 retracts, driving the second push plate 11 to return to its original position. This completes one round of fruit tree planting pit digging, soil collection, and backfilling operation. The vehicle body 1 can then be moved to the next planting location to repeat the above process.

[0058] It should be noted that a cover plate can be installed on the auxiliary pit later to prevent blockage during soil backfilling.
