Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a machine for drilling holes to assist in supporting planting holes. Background Technology

[0002] As a crucial strategic project to safeguard national timber security and enhance ecosystem functions, the National Reserve Forest Construction Project faces an increasingly prominent demand for large-scale and efficient seedling planting. Standardized tree planting operations heavily rely on efficient and reliable mechanized equipment. However, the technical bottlenecks exposed by traditional planting hole drilling machinery in practical applications, especially in large-scale afforestation scenarios such as the National Reserve Forest, have become key factors restricting project progress and quality.

[0003] Existing technology (usually referring to auger drilling machinery) primarily uses a diesel engine to drive the drill shaft to rotate, which in turn drives the auger blades to directly excavate the soil. This technical solution has the following significant drawbacks:

[0004] Soil slippage and back into the planting hole is a problem: During the excavation process, the auger blades throw soil directly upwards. However, when the auger blades are lifted or removed from the planting hole, a large amount of the thrown soil easily slips or falls back into the excavated hole. This is particularly prominent in large-scale operations where thousands of planting holes need to be completed daily. Operators are forced to perform frequent and time-consuming repetitive hole-clearing operations, which seriously affects the timeliness of seedling planting, significantly reduces overall operational efficiency, and increases labor costs.

[0005] Poor adaptability to complex terrain and insufficient operational stability: National reserve forest construction projects are mostly located in complex terrain areas such as hills and mountains. Traditional drilling machinery generally uses diesel engines as the power source, and its support structure (chassis, outriggers, etc.) is often designed for flat ground conditions, which is significantly insufficient for slope operations. The high center of gravity of the diesel engine and the whole machine, as well as the imperfect layout of support points or leveling mechanisms, result in poor stability of the machinery when operating on slopes, making it prone to shaking, tilting, or even slippage. This not only reduces the verticality and quality of the borehole (affecting seedling survival and posing safety hazards), but also further limits the operating efficiency and applicability of the equipment under complex terrain conditions.

[0006] In summary, existing planting hole drilling machinery cannot effectively meet the core requirements of national reserve forest construction for high efficiency, low rework rate, and high stability in complex terrain. There is an urgent need to develop a new type of drilling equipment that can fundamentally solve the problem of soil slippage and backfilling, and significantly improve operational stability and adaptability in complex terrain conditions such as hills and mountains. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary support for drilling planting holes, so as to solve the problems of soil slippage back into the pit, poor adaptability to complex terrain, and insufficient operational stability of existing drilling machines.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0009] A machine for drilling planting holes to assist in support includes a support frame, a spiral drill, a drill rod, a spiral drill disc, soil chips, a support rod, a support caster, a first rotating rod, a second rotating rod, an electric push rod, and a guide rod. The spiral drill is mounted on the support frame, and a drill rod is located below the spiral drill. A spiral drill disc is provided on the surface of the drill rod, and several soil chips are evenly distributed on the outer side of the spiral drill disc. Two support rods are symmetrically arranged on the support frame. One end of the support rod is rotatably connected to the support frame via a rotating shaft, and the other end is provided with a support caster. The first rotating rod and the second rotating rod are rotatably fixed to the two support rods respectively. One end of the guide rod is fixedly connected to the first rotating rod, and the other end passes through the second rotating rod and is provided with an electric push rod. The electric push rod achieves relative tightening of the first rotating rod and the second rotating rod by pulling the guide rod.

[0010] Furthermore, it also includes handles, fixing plates, guide rods, and foot pedals. Fixing plates are symmetrically arranged on both sides of the support frame. The fixing plates are rectangular flat plate structures with a circular hole in the center and circular channels on both sides for fixing the handles. The guide rods are a combination structure of a conical section and a cylindrical end, and foot pedals are fixedly installed near the conical section.

[0011] Furthermore, the loose soil sheets are rectangular block structures, placed on the auger spool, with gaps between them.

[0012] Furthermore, it also includes control buttons, two symmetrically arranged handles, the handles passing through the fixed plate with an arc-shaped bend, and control buttons at the ends of the handles.

[0013] Furthermore, it also includes magnets, with magnets provided on the surface of the fixing plate at positions corresponding to the foot pedals.

[0014] Furthermore, the auger drilling rig is equipped with a push rod power supply component, which is connected to an electric push rod.

[0015] Furthermore, the guide rod is set parallel to the drill pipe.

[0016] This utility model has the following beneficial effects:

[0017] Effectively solving the problem of soil slippage back into the planting hole and significantly improving work efficiency, the installation of soil-loosening plates on the spiral turntable greatly reduces soil slippage back into the planting hole during drilling, directly avoiding the frequent repeated hole cleaning operations required in existing technologies. Enhancing the stability and adaptability of operations in complex terrain, the double fixation of the support rod and guide rod significantly reduces equipment swaying and tilting when operating on slopes, ensuring the verticality of the borehole, improving the quality of the planting hole, and promoting seedling survival. Simultaneously, it greatly reduces the safety risks of equipment operation in complex terrain, improving work efficiency and reliability under such conditions. Attached Figure Description

Detailed Implementation

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1

[0023] Please refer to Figure 1-2 This utility model provides an auxiliary support for drilling planting holes, including a support frame 1. The support frame 1 serves as the main frame of the entire machine, on which a spiral drill 3, providing drilling power, is mounted. The spiral drill 3 is preferably a diesel engine to adapt to the needs of operations in environments without power supply. A drill rod 4 is connected to the power output end of the spiral drill 3, and a spiral drill disc 5 is welded and fixed to the surface of the drill rod 4 for excavating soil.

[0024] To address the issue of soil slippage, several soil-loosening plates 6 are uniformly welded to the outer edge of the auger disc 5. In this embodiment, the soil-loosening plates 6 are preferably rectangular blocks, maintaining a specific inclination angle with the helix angle of the auger disc 5. When the drill rod 4 rotates at high speed, the auger disc 5 transports the soil upwards. Upon reaching the top soil-loosening plates 6, due to the centrifugal force and specific angle design, the soil is thrown with a greater horizontal speed and force to a position far from the pit opening. This effectively prevents the soil from slipping back into the pit due to gravity, reduces repeated pit cleaning operations, and significantly improves the efficiency of single-pit excavation.

[0025] To address the issue of poor stability during operations in complex terrain, this invention designs an auxiliary support system. This system includes a support wheel assembly and a vertical guide.

[0026] The support wheel assembly includes two support rods 7 symmetrically arranged on both sides of the support frame 1. The upper end of each support rod 7 is rotatably connected to the support frame 1 via a pivot, and the lower end is rotatably mounted with a support caster 8 for easy movement and steering of the machine. To achieve automatic opening and closing of the support rods 7 and adjustment of the support angle, a linkage control mechanism is provided. Specifically, a first rotating rod 9 is rotatably mounted on the inner surface of the upper part of one support rod 7, and a second rotating rod 10 is rotatably mounted at the corresponding position on the other support rod 7. The housing of an electric push rod 11 is fixedly mounted on one end of the second rotating rod 10, and the telescopic end of the electric push rod 11 is fixedly connected to one end of the first rotating rod 9. At the same time, a guide rod 12 is fixedly connected to the other end of the first rotating rod 9, and the guide rod 12 movably passes through a hole opened at the end of the second rotating rod 10.

[0027] During operation, the operator activates the electric push rod 11 via the control button 18 located at the end of the handle 2. The electric push rod 11 is powered by a push rod power supply unit 17 (such as a small generator or battery pack; in this embodiment, a battery pack is used) attached to the auger drill 3. When the electric push rod 11 extends, it pushes the first rotating rod 9, and through the extension and retraction of the guide rod 12, separates the first rotating rod 9 and the second rotating rod 10, thereby causing the two support rods 7 to unfold outwards, supporting the casters 8 to land and forming a stable support structure, greatly improving the stability of the machinery on slopes or uneven ground. After operation, the electric push rod 11 retracts, pulling the first rotating rod 9 to retract the two support rods 7 inwards, facilitating movement to the next work point.

[0028] To further enhance vertical stability during drilling and prevent machine body swaying or displacement caused by uneven force on the drill bit, this invention also includes a vertical guide. This vertical guide includes fixed plates 13 symmetrically arranged on both sides of the support frame 1. The fixed plates 13 are rectangular flat plates with a circular hole in the center for the guide rod 15 to pass through, and channels on both sides for the handle 2 to pass through and be fixed. The handle 2 is designed with an arc-shaped bend, conforming to ergonomics, making it easy for the operator to grip and apply force.

[0029] The lower end of the guide rod 15 is a conical section for easy insertion into the soil, while the upper end is a cylindrical section that movably engages with the circular hole in the fixing plate 13. A foot pedal 16 is welded to the guide rod 15 near the conical section. For easy storage, a magnet 14 is positioned on the upper surface of the fixing plate 13, corresponding to the foot pedal 16. In non-operating conditions or during movement, the operator can lift the guide rod 15 upwards, causing the foot pedal 16 to magnetically engage with the magnet 14, reliably securing the guide rod 15 in the retracted position. Before drilling, the operator presses down on the foot pedal 16, inserting the conical end of the guide rod 15 into the ground. Its shaft is parallel to the drill rod 4, providing a stable vertical anchor point for the entire machine and effectively resisting the torque and vibration generated during drilling.

[0030] The workflow of this utility model is as follows:

[0031] 1. Moving and positioning: The operator holds handle 2 and, with the support rod 7 retracted, uses the support casters 8 to easily push the machine to the predetermined planting hole.

[0032] 2. Deploy support: Press control button 18 to activate electric push rod 11 to extend it, support rod 7 to unfold outward, support caster 8 to land and form stable support.

[0033] 3. Vertical Anchoring: The operator steps on the foot pedal 16 to release the attraction with the magnet 14 and inserts the guide rod 15 into the soil.

[0034] 4. Drilling operation: Start the auger drill rig 3. The drill rod 4 drives the auger drill disc 5 and the soil-spreading blades 6 to rotate and excavate. The excavated soil is effectively thrown out of the pit by the soil-spreading blades 6.

[0035] 5. Retraction and Transfer: After drilling is completed, lift drill rod 4, pull out guide rod 15 upwards and fix it to magnet 14. Press control button 18 again to retract electric push rod 11 and extend support rod 7. Then move to the next work point and repeat the above steps.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
