Description

Technical Field

[0001] This utility model relates to the field of slope greening construction technology. More specifically, this utility model relates to a device for drilling planting holes for greening roadbed slopes in loess areas. Background Technology

[0002] Loess landforms are topographic features developed within loess strata, characterized by high porosity, well-developed vertical joints, and low water content. Planting vegetation is commonly used for the stability protection of loess slopes, improving slope stability while greening the environment. However, planting vegetation requires drilling planting holes. Currently, drilling these holes relies on manual labor using drilling rigs, which drill sequentially according to the designed locations. This method is inefficient, and the slope's gradient makes it difficult to ensure the verticality of the holes. Furthermore, the lack of protective measures during drilling results in significant dust generation. Summary of the Invention

[0003] The purpose of this utility model is to provide a device for drilling planting holes for greening roadbed slopes in loess areas, so as to solve the technical problem that the lack of guiding and limiting assistance in the existing technology when drilling planting holes in loess slope greening construction makes it difficult to hold and operate the equipment to maintain the verticality of the drilling.

[0004] To achieve these objectives and other advantages according to this utility model, a device for drilling planting holes for greening roadbed slopes in loess areas is provided, comprising:

[0005] The bracket includes a base plate, a mounting hole is provided in the middle of the base plate, a handle is detachably connected to one side of the base plate outside the mounting hole, and a lead screw nut is embedded and fixed on the base plate outside the handle, with the axis of the lead screw nut being perpendicular to the base plate.

[0006] The drilling rig is fixedly installed on the mounting hole. The drilling rig has a drill rod that extends away from the handle and drills planting holes toward the slope surface through the drill rod.

[0007] The support rod has a lead screw section at one end and a strut section at the other end. The support rod is threadedly connected to the lead screw nut through the lead screw section to pass through the substrate. The strut section and the drill rod are located on the same side of the substrate. The cross-sectional shape and size of the strut section and the planting hole are the same. The length of the support rod is greater than the distance between the end of the drill rod and the substrate. The distance between the support rod and the drill rod is the same as the spacing between adjacent planting holes.

[0008] Preferably, the device further includes a dustproof frame disposed on the side of the substrate facing away from the handle. The dustproof frame includes a support ring plate and a sliding ring plate. The support ring plate is disposed around the outside of the drill rod in a direction perpendicular to the substrate and is fixedly connected to the corresponding position of the substrate. The sliding ring plate is slidably connected to the support ring plate in a coaxial direction. The end of the sliding ring plate near the substrate is a sliding end, and the maximum distance between the sliding end and the substrate is greater than the depth of the hole.

[0009] Preferably, a retaining ring is provided inward at the end of the support ring plate away from the substrate, the sliding ring plate is slidably connected to the inner side of the support ring plate, and a sliding ring is provided outward at the sliding end. In the free state, the bottom surface of the sliding ring abuts against the top surface of the retaining ring.

[0010] Preferably, the lead screw nut is symmetrically arranged on the base plate relative to the drilling rig, and a support rod is respectively installed inside the lead screw nut on both sides.

[0011] Preferably, a stop cover is provided at the upper end of the lead screw section, and the diameter of the stop cover is larger than the inner diameter of the lead screw nut.

[0012] Preferably, the lower end of the lead screw section is detachably connected to the support rod section in the coaxial direction, and the length of the support rod section is greater than the axial distance between the bottom of the dustproof frame in the free state and the end of the drill rod.

[0013] Preferably, a spiral blade is fixedly wrapped around the outer side of the drill rod along the axial direction.

[0014] This utility model has at least the following beneficial effects: The planting hole drilling device for greening roadbed slopes in loess areas includes a bracket, a drilling rig, and a support rod. The bracket includes a base plate, and the drilling rig is installed in the middle of the base plate. A screw nut and a support rod are provided on the outer side of the base plate. The support rod and the screw nut are connected by a thread, which can flexibly adjust the length of the support rod extending out of the base plate. During the drilling process, the support rod is aligned and inserted into the adjacent drilled holes, which guides the positioning and verticality of the drilling rig when drilling the current hole. At the same time, by adjusting the support rod, the drilling depth of the drilling rod can be ensured to be consistent. The operator only needs to hold the handle on the base plate to quickly drill holes, which greatly reduces the difficulty and labor intensity of drilling holes on slopes, which requires manual control of the drilling direction and raising the drilling rig throughout the process. This improves the safety and efficiency of slope construction.

[0015] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0020] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1 , Figure 2 As shown, the device for drilling planting holes for greening roadbed slopes in loess areas according to this utility model includes:

[0022] The bracket includes a base plate 1, a mounting hole is provided in the middle of the base plate 1, and a handle 2 is detachably connected to one side of the base plate 1 outside the mounting hole. A lead screw nut 3 is embedded and fixed on the base plate 1 at the outside position of the handle 2, and the axis of the lead screw nut 3 is perpendicular to the base plate 1.

[0023] Drilling rig 4 is fixedly installed on the mounting hole. Drilling rig 4 has a drill rod 6, which extends away from the handle 2. The drill rod 6 is used to drill planting holes 7 towards the slope surface.

[0024] The support rod 8 has a lead screw section 9 at one end and a strut section 10 at the other end. The support rod 8 is threadedly connected to the lead screw nut 3 through the lead screw section 9 to pass through the base plate 1. The strut section 10 and the drill rod 6 are located on the same side of the base plate 1. The cross-sectional shape and size of the strut section 10 and the planting hole 7 are the same. The length of the support rod 8 is greater than the distance between the end of the drill rod 6 and the base plate 1. The distance between the support rod 8 and the drill rod 6 is the same as the spacing between adjacent planting holes 7.

[0025] Before drilling the planting hole 7, the drill rig 4 is installed and fixed on the bracket, with one end of the drill rod 6 serving as the drilling operation end for the planting hole 7. Then, the handle 2 is installed on the substrate 1, with the handle 2 located at... Figure 1At the upper end, i.e., the end where the drill rig 4 is located, opposite to the end of the drill rod 6, a support rod 8 is screwed into the screw nut 3 on the base plate 1. The end of the support rod 8 with the strut section 10 is on the same side as the drill rod 6. If the first hole 7 is to be drilled at this time, the support rod 8 can be adjusted upwards to avoid obstructing the drilling operation of the drill rod 6. If the drilling of the adjacent second hole 7 is to begin, the support rod 8 can be moved within the screw nut 3 so that the lower end of the support rod 8 is at the same distance from the end of the drill rod 6 relative to the base plate 1. When the drill rod 6 is in operation, the operator holds the handle 2, and the support rod 8 is aligned with the previously drilled hole. At the location of hole 7 on the slope, support rod 8 serves as a positioning mechanism when drilling adjacent planting holes 7. During the operation of drilling rig 4, as support rod 8 extends along the already drilled planting hole 7, it guides the drilling of drill rod 6, which helps to ensure the verticality of drilling holes 7. When support rod 8 touches the bottom, drill rod 6 stops drilling, ensuring that the drilling depth of planting holes 7 is the same. During the operation of drilling rig 4, the bracket and support rod 8 together form a support system for drilling rig 4, reducing the difficulty and labor intensity for operators in aligning the drilling operation and supporting the overall structure of drilling rig 4.

[0026] In another technical solution, such as Figure 1-2 As shown, it also includes a dustproof frame 11 disposed on the side of the substrate 1 facing away from the handle 2. The dustproof frame 11 includes a support ring plate 12 and a sliding ring plate 13. The support ring plate 12 is disposed around the outside of the drill rod 6 in a direction perpendicular to the substrate 1 and is fixedly connected to the corresponding position of the substrate 1. The sliding ring plate 13 is slidably connected to the support ring plate 12 in a coaxial direction. The end of the sliding ring plate 13 near the substrate 1 is the sliding end. The maximum distance between the sliding end and the substrate 1 is greater than the depth of the planting hole 7.

[0027] The sliding ring plate 13 and the supporting ring plate 12 can slide freely relative to each other. Before drilling the planting hole 7, the sliding ring plate 13 hangs freely on the outside of the drill rod 6, at a certain height above the end of the drill rod 6. As the drill rod 6 penetrates into the loess, the bottom of the sliding ring plate 13 is opened to contact the slope surface, which protects the outside of the drill rod 6 and prevents dust. The drill rod 6 continues to drill, and the sliding end slides upward along the axis relative to the supporting ring plate 12 without affecting the downward movement of the drill rod 6, and also avoids affecting the flatness of the slope surface. It always stays on the outside of the drill rod 6 on the slope surface until the planting hole 7 is completed. The support is lifted, and the sliding ring plate 13 moves back to its original position at the bottom.

[0028] In another technical solution, such as Figure 1-2 As shown, a retaining ring is provided inward at the end of the support ring plate 12 away from the base plate 1, the sliding ring plate 13 is slidably connected to the inner side of the support ring plate 12, and a sliding ring 14 is provided outward at the sliding end. In the free state, the bottom surface of the sliding ring 14 abuts against the top surface of the retaining ring.

[0029] In the free state, that is, before drilling, the sliding ring 14 of the sliding ring plate 13 rests on the retaining ring, forming a limit on the lower side of the sliding ring plate 13, preventing the sliding ring plate 13 from detaching from the supporting ring plate 12. During the relative sliding process, the sliding ring 14 slides up and down on the inner side of the supporting ring plate 12.

[0030] In another technical solution, such as Figure 1-2 As shown, the lead screw nut 3 is symmetrically arranged on the base plate 1 relative to the drilling rig 4, and a support rod 8 is respectively installed inside the lead screw nut 3 on both sides. The symmetrical arrangement of a set of lead screw nuts 3 and support rods 8 on both sides of the drilling rig 4 can further improve the support balance and verticality guidance ability of the support rod 8 for drilling the drilling rod 6 to drill the planting hole 7.

[0031] In another technical solution, such as Figure 1-2 As shown, a cover 15 is provided at the upper end of the lead screw section 9. The diameter of the cover 15 is larger than the inner diameter of the lead screw nut 3 to prevent the support rod 8 from disengaging from the lead screw nut 3.

[0032] In another technical solution, such as Figure 1-2 As shown, the lower end of the lead screw section 9 is detachably connected to the support rod section 10 along the coaxial direction, which improves the flexibility of the support rod 8 installation. At the same time, the support rod section 10 structure with the corresponding diameter can be replaced according to different planting hole 7 diameters. The length of the support rod section 10 is greater than the axial distance between the bottom of the dustproof frame 11 in the free state and the end of the drill rod 6, so that the support rod 8 can meet the required support height range corresponding to the planting hole 7 depth range drilled by the drill rod 6.

[0033] In another technical solution, such as Figure 1-2 As shown, a spiral blade 5 is fixedly wrapped around the outer side of the drill rod 6 along the axial direction to improve the drilling capability of the drill rod 6.

[0034] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the drawings shown and described herein.
