Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a drilling device for planting in tropical coral soil. Background Technology

[0002] Tropical coral soil, due to its unique geological characteristics such as high porosity, low density, and rich organic matter and salt content, places special requirements on drilling equipment for planting. Traditionally, drilling in this type of soil mainly relies on manual operation, that is, holding a drill bit and repeatedly striking with a hammer to penetrate the target layer.

[0003] However, this method has significant drawbacks: on the one hand, manual hammering requires continuous high-intensity physical labor, especially when facing hard coral reefs or strata rich in shell fragments, it often takes a lot of time and energy to complete a simple planting hole; on the other hand, since the operation relies entirely on manual hammering, the drilling depth and diameter are difficult to control precisely, which can easily lead to irregularly shaped holes and affect the subsequent planting results.

[0004] Therefore, it is necessary to provide a drilling device for planting tropical coral soil to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for planting tropical coral soil, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drilling device for planting in tropical coral soil includes:

[0008] Support body;

[0009] A rotating assembly includes a threaded pipe, a connecting pipe, a sleeve, a drill bit, a foot pedal, and a grounding cone. Two sleeves and two foot pedals are provided, and multiple grounding cones are provided. The threaded pipe is threadedly connected to the surface of the support body. The drill bit is fixedly connected to the lower end of the threaded pipe. The connecting pipe is threadedly connected to the circumferential surface of the threaded pipe. Two sleeves are fixedly connected to both sides of the surface of the connecting pipe. Two foot pedals are fixedly connected to the surface of the support body, and multiple grounding cones are fixedly connected to the lower end of the support body.

[0010] The telescopic assembly is provided in two sets, with each set of the telescopic assembly located on one side of the threaded pipe;

[0011] Water injection assembly, wherein the water injection assembly is disposed inside the threaded pipe.

[0012] As a preferred embodiment of this utility model, each telescopic assembly includes a telescopic rod, a limiting ball, a spring, a placement groove, and a limiting hole. Multiple limiting holes are provided. The telescopic rod is slidably connected to the inner wall of the sleeve. The placement groove is opened on the surface of the telescopic rod. Multiple drill bits are opened on the surface of the sleeve. The spring is fixedly connected to the inner wall of the placement groove. The limiting ball is fixedly connected to the surface of the spring. The limiting ball is slidably connected to the inner wall of one of the limiting holes.

[0013] In a preferred embodiment of this utility model, the water injection assembly includes a water storage tank, a knob, a rotating ball, a rotating rod, and drain holes. Multiple drain holes are provided. The water storage tank is threaded to the inner wall of the connecting pipe. All drain holes are located on the circumferential surface of the drill bit. The rotating ball is rotatably connected to the inner wall of the connecting pipe. One end of the rotating rod slides through one end of the connecting pipe, and one end of the rotating rod is fixedly connected to the surface of the rotating ball. The knob is fixedly connected to the surface of the rotating rod.

[0014] As a preferred embodiment of this utility model, multiple anti-slip rods are fixedly connected to the surfaces of both foot pedals.

[0015] As a preferred embodiment of this utility model, the surface of the drill bit is provided with graduations.

[0016] As a preferred embodiment of this utility model, anti-slip grooves are provided on the surfaces of both telescopic rods.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this solution, the device significantly improves the stability and efficiency of drilling operations in tropical coral soil through the coordinated fixing structure of the main support body, the ground-inserting cone, and the foot pedal, combined with a rotary-driven drill bit. When the operator steps on the foot pedal, the anti-slip bars on both sides effectively prevent the foot from sliding left and right, ensuring the stability of the device; the rotating sleeve drives the threaded pipe and drill bit to drill vertically downwards, replacing the traditional hammering mode, greatly reducing labor intensity while avoiding hole deviation. The scale on the drill bit surface provides an intuitive depth reference, and with the adjustable lever arm telescopic component, precise depth control and efficient drilling are achieved, solving the technical problems of easy fatigue during manual operation and difficulty in controlling the hole direction.

[0019] 2. In this design, the device integrates a telescopic assembly and a water injection assembly, further optimizing adaptability and operational quality. The telescopic rod, through the engagement of a limiting ball and a limiting hole, allows for flexible adjustment of the lever arm length based on soil hardness. In soft soil, the lever arm is shortened to increase speed, while in hard soil, the lever arm is lengthened to enhance torque, balancing efficiency and stability. The water injection assembly evenly injects water into the drilling area through a water tank, softening the soil and lubricating the drill bit, significantly reducing frictional resistance, extending tool life, and maintaining balanced humidity within the hole, providing an ideal environment for subsequent planting. This design comprehensively addresses the problems of low efficiency, reliance on experience-based judgment, and rapid equipment wear associated with traditional methods. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] Please see Figures 1-5 The present invention provides the following technical solution:

[0030] A drilling device for planting in tropical coral soil includes:

[0031] Support body 1;

[0032] The rotating assembly includes a threaded pipe 2, a connecting pipe 3, a sleeve 5, a drill bit 7, a foot pedal 18, and a ground-inserting cone 20. There are two sleeves 5 and two foot pedals 18, and multiple ground-inserting cones 20. The threaded pipe 2 is threaded to the surface of the support body 1. The drill bit 7 is fixedly connected to the lower end of the threaded pipe 2. The connecting pipe 3 is threaded to the circumferential surface of the threaded pipe 2. The two sleeves 5 are fixedly connected to both sides of the surface of the connecting pipe 3. The two foot pedals 18 are fixedly connected to the surface of the support body 1. The multiple ground-inserting cones 20 are fixedly connected to the lower end of the support body 1.

[0033] The telescopic assembly consists of two sets, each set being located on one side of the threaded pipe 2.

[0034] Water injection component, which is installed inside threaded pipe 2.

[0035] In a specific embodiment of this utility model, after placing the support body 1 on the ground, the device initially fixes the support body 1 by inserting multiple ground-inserting cones 20 into the ground. However, since the ground-inserting cones 20 alone cannot completely stabilize the support body 1, the operator needs to stand on two foot pedals 18 and rely on their own weight to further stabilize the device. Then, the operator grabs the sleeves 5 on both sides and applies rotational force. Since the sleeves 5 form a threaded connection structure with the threaded pipe 2 through the connecting pipe 3, and the direction of the threaded connection between the connecting pipe 3 and the threaded pipe 2 is consistent with the direction of the drill bit 7 drilling downwards, the connecting pipe 3 is prevented from detaching from the threaded pipe 2. The lower end of the threaded pipe 2 is fixedly connected to the drill bit 7. Therefore, rotating the sleeves 5 can synchronously drive the threaded pipe 2 to rotate, so that the drill bit 7 drills downwards along the axis of the threaded pipe 2. Compared with the traditional hammering method, there is no need to repeatedly hit the drill bit. The drill bit 7 is driven vertically by continuous rotation by human power, which greatly reduces the labor intensity and prevents the hole from deviating. At the same time, the threaded transmission structure converts the rotational motion into linear displacement, so that the drill bit accurately cuts into the soil layer, significantly improving the work efficiency and hole quality.

[0036] Please refer to the details. Figures 1-5 Each telescopic assembly includes a telescopic rod 6, a limiting ball 14, a spring 15, a placement groove 16, and a limiting hole 17. Multiple limiting holes 17 are provided. The telescopic rod 6 is slidably connected to the inner wall of the sleeve 5. The placement groove 16 is opened on the surface of the telescopic rod 6. Multiple drill bits 7 are opened on the surface of the sleeve 5. The spring 15 is fixedly connected to the inner wall of the placement groove 16. The limiting ball 14 is fixedly connected to the surface of the spring 15. The limiting ball 14 is slidably connected to the inner wall of one of the limiting holes 17.

[0037] In this embodiment: the telescopic component is slidably connected to the inner wall of the sleeve 5 via the telescopic rod 6 to achieve length adjustment. When the limiting ball 14 is pressed to disengage it from the limiting hole 17, the spring 15 is compressed and stores energy, pushing the limiting ball into the next limiting hole to complete positioning, thereby changing the extension length of the telescopic rod 6. Since the limiting ball 14 is a spherical structure, it can slide freely and lock securely in the limiting hole 17. The operator can flexibly adjust the lever arm length according to the soil hardness. In soft soil, the lever arm is shortened to speed up the drilling speed, and in hard soil, the lever arm is lengthened to increase the torque output. The multi-stage limiting hole design ensures adjustment accuracy. Combined with the rotation drive of the threaded tube 2, it adapts to complex geological conditions and avoids excessive force that could damage the equipment, effectively balancing efficiency and stability.

[0038] Please refer to the details. Figures 1-5 The water injection assembly includes a water storage tank 4, a knob 9, a rotating ball 11, a rotating rod 12, and drain holes 13. Multiple drain holes 13 are provided. The water storage tank 4 is threaded to the inner wall of the connecting pipe 3. Multiple drain holes 13 are opened on the circumferential surface of the drill bit 7. The rotating ball 11 is rotatably connected to the inner wall of the connecting pipe 3. One end of the rotating rod 12 slides through one end of the connecting pipe 3. One end of the rotating rod 12 is fixedly connected to the surface of the rotating ball 11. The knob 9 is fixedly connected to the surface of the rotating rod 12.

[0039] In this embodiment: the water injection component drives the rotating rod 12 to rotate the rotating ball 11 through the rotating knob 9. The water in the water storage tank 4 flows into the connecting pipe 3 through the small hole in the center of the rotating ball, and then is evenly sprayed out to the drilling area through the drainage hole 13 on the surface of the drill bit 7. The injected water can soften soil particles and form a lubricating film, reduce the frictional resistance between the drill bit and the soil layer, reduce energy consumption and prevent the drill bit from wearing due to high temperature. In addition, the water flow is distributed along the inner wall of the borehole to maintain the humidity balance in the hole, avoid dryness and clumping that will affect subsequent planting, and the water injection volume can be adjusted by controlling the opening of the knob to achieve precise irrigation and improve planting efficiency.

[0040] Please refer to the details. Figures 1-5 Multiple anti-slip bars 19 are fixedly connected to the surfaces of both foot pedals 18.

[0041] In this embodiment: two anti-slip rods 19 are fixedly connected to the surfaces of the two foot pedals 18, and each anti-slip rod 19 is symmetrically distributed on the left and right sides of the foot pedal 18; when the operator stands on the foot pedal 18 to perform drilling operations, the outer edge of the foot will fit against the extended surface of the anti-slip rod 19. Through the physical blocking effect formed by the anti-slip rod 19 and the side of the shoe upper, the foot is effectively prevented from sliding left and right due to rotational torque. Its lateral support structure can withstand lateral force and disperse foot pressure, avoiding safety hazards caused by center of gravity shift.

[0042] Please refer to the details. Figures 1-5The surface of drill bit 7 is marked with graduations 8.

[0043] In this embodiment, the scale 8 on the surface of the drill bit 7 provides an intuitive depth reference through equidistant markings. The operator can accurately judge whether the drilling depth has reached the target value by observing the scale lines, avoiding waste of resources due to excessive depth or affected planting effect due to visual error.

[0044] Please refer to the details. Figures 1-5 Both telescopic rods 6 have anti-slip grooves 10 on their surfaces.

[0045] In this embodiment: the anti-slip groove 10 on the surface of the telescopic rod 6 can increase the contact area between the operator's palm and the rod body, and improve the grip stability; the groove structure can also quickly wick away sweat to keep the hands dry and avoid operational errors in wet and slippery environments.

[0046] The working principle and usage process of this utility model are as follows: The device initially fixes the ground through the support body 1 and the ground-inserting cone 20. The operator steps on the foot pedal 18 and uses the anti-slip rod 19 to prevent the foot from slipping left and right. By rotating the sleeves 5 on both sides, the threaded tube 2 drives the drill bit 7 to drill vertically downward. The telescopic component adjusts the length of the telescopic rod 6 by pressing the limiting ball 14 to disengage from the limiting hole 17, so that the lever arm can flexibly adapt to different soil hardness. Shortening the lever arm improves the efficiency in soft soil, and lengthening the lever arm enhances the torque in hard soil. The water injection component controls the water flow in the water tank 4 through the rotating ball 11 to enter the drill bit 7 through the drain hole 13, which is then evenly sprayed into the hole to reduce the resistance of the drill bit and maintain the humidity balance in the hole. This device replaces manual hammering with mechanical linkage, which significantly reduces labor intensity and avoids hole deviation. The dynamic lever arm adjustment adapts to complex geological conditions and improves drilling efficiency. The water injection system reduces friction loss and optimizes the hole quality, solving the problems of time-consuming, labor-intensive, unstable, inefficient and severely worn tools in traditional drilling methods, and realizing efficient, precise and safe tropical coral soil planting operations.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
