Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of environmental engineering, and particularly relates to a hole opening tool for sowing holes. BACKGROUND

[0002] The ecological bag is a double-sided ironed needle-punched non-woven bag made of polypropylene (PP) or polyester fiber (PET), which has many advantages such as moisture resistance, chemical corrosion resistance (PH), biological degradation resistance, animal damage resistance, high polymer resistance, ultraviolet resistance (UV) and the like, and is widely used in many fields. The most typical application is ecological slope protection, that is, to build a flexible ecological slope.

[0003] In the related art, when building a flexible ecological slope, a hole opening tool can be used to open some small holes (referred to as sowing holes) on the surface of the ecological bag, so as to scatter plant seeds into the sowing holes, and then cover the soil, so as to realize the sowing (also referred to as sowing) of the plant seeds. However, the opening end of the existing hole opening tool is mostly solid pick or steel bar (sometimes processed into a hammer shape), which essentially belongs to extrusion type hole opening. The extrusion type hole opening has the following disadvantages: the soil in the ecological bag is very dense after being tamped and settled during piling, the extrusion type hole opening makes the soil in the ecological bag more dense, which is not conducive to the penetration and storage of rainwater or maintenance water to the soil around the hole (that is, the soil around the sowing hole) after sowing, and it is difficult to effectively and continuously provide water for the germination of the plant seeds, which affects the root growth of the plant seeds after germination; the solid opening end is difficult to cut the non-woven fabric all around, and the non-woven fabric in the opening area is usually partially cut and the remaining part is connected with the periphery, so as to be suspended and covered on the hole opening, which inhibits the emergence of the plant seeds after germination; the soil in the ecological bag cannot be directly taken out during the hole opening process, and after the plant seeds are sowed, the soil is not covered, which makes it difficult to guarantee the water required for the germination of the plant seeds, or the soil needs to be taken out additionally or carried to cover the plant seeds, which reduces the efficiency of the sowing operation. CONTENT OF THE UTILITY MODEL

[0010] In some implementations, the outer wall of the perforated tube is provided with a plurality of limit hole groups, each of which includes at least one limit hole. The plurality of limit hole groups are located between the perforated end and the handle and are spaced apart along the axis of the perforated tube.

[0016] In the related art, the perforating end of the hole opening tool for the dibbling hole on the ecological bag is mostly a solid pick or reinforcing bar (sometimes processed into a hammer shape), which essentially belongs to extrusion type hole opening. However, the soil in the ecological bag is very dense after being tamped and settled during the piling, and the extrusion type hole opening makes the soil in the ecological bag even denser, which is not conducive to the penetration and storage of rainwater or maintenance water to the soil around the hole after dibbling, and it is difficult to effectively and continuously provide water for the germination of plant seeds, affecting the root growth of the plant seeds after germination. The solid hole opening end is difficult to cut the non-woven fabric all around, and the non-woven fabric in the hole opening area is usually partially cut and the remaining part is connected to the periphery, thereby being suspended and covered on the hole opening, which inhibits the emergence of the plant seeds after germination. The hole opening depth is difficult to control, and if the hole opening is too shallow, the plant seeds float on the surface or the cover soil is too thin, which reduces the water retention, and the plant seeds are difficult to germinate, and if the hole opening is too deep, the plant seeds are dibbled too deep or the cover soil is too thick, which makes the plant seeds difficult to emerge and even easy to rot, ultimately resulting in a low emergence rate of the plant seeds. The hole opening process cannot directly take out the soil in the ecological bag, and after the plant seeds are dibbled, either no soil is covered, which makes it difficult to guarantee the water required for the germination of the plant seeds, or additional soil needs to be taken out or carried to cover the plant seeds, which reduces the efficiency of the dibbling operation.

[0017] Therefore, in the embodiments below, the present application proposes a dibbling hole opening tool, which belongs to a knife cutting type hole opening. When the dibbling hole opening tool is used to open a dibbling hole on the surface of an ecological bag, the following advantages are achieved: the knife cutting type hole opening does not make the soil in the ecological bag even denser, which is conducive to the penetration and storage of rainwater or maintenance water to the soil around the hole after dibbling, and can effectively and continuously provide water for the germination of plant seeds, ensuring the root growth of the plant seeds after germination; the hollow hole opening end can cut the non-woven fabric all around, and the non-woven fabric in the hole opening area will not be partially connected to the periphery like the traditional scheme, i.e., it will not be suspended and covered on the hole opening, ensuring the emergence of the plant seeds after germination; the hole opening depth can be controlled, avoiding the disadvantages of the traditional scheme when the hole opening is too shallow or too deep, and improving the emergence rate of the plant seeds; the hole opening process can directly take out the soil in the ecological bag, and after the plant seeds are dibbled, the soil taken out from the ecological bag can be used to cover the plant seeds, without the need for additional soil to be taken out or carried to cover the plant seeds, thereby improving the efficiency of the dibbling operation. Therefore, for plant seeds dibbled using an ecological bag, the dibbling hole opening tool of the present application not only improves the survival rate of the plant seeds and reduces the growth obstacles, but also improves the efficiency of the dibbling operation.

[0018] In order to make the purpose, technical scheme and advantages of the present application more obvious and easy to understand, the present application will be described clearly and completely below in combination with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. It should be understood that the embodiments of the present application described below are only used to explain the present application and do not limit the present application, that is, all other embodiments obtained by those skilled in the art without creative labor based on the various embodiments of the present application belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0019] Please refer to Figure 1 , Figure 1 is a structural schematic view of the hole opening tool from a perspective. The present embodiment provides a hole opening tool, which comprises a handle 100 and a hollow opening pipe 200, one end of the handle 100 is arranged on the outer wall of the opening pipe 200, the opening pipe 200 has an opening end 210, and the opening end 210 has an opening port 211 which is in communication with the inside of the opening pipe 200. In the actual process of opening the hole, the user can hold the handle 100 and apply force, the handle 100 can transmit the force applied by the user to the opening pipe 200, so that the opening pipe 200 moves towards the surface of the ecological bag, the opening end 210 of the opening pipe 200 penetrates into the ecological bag, and the soil in the ecological bag is collected in the opening pipe 200 through the opening port 211, then the user can pull out the opening pipe 200 from the ecological bag, and the soil at the corresponding position on the ecological bag will also be taken away from the ecological bag due to being collected in the opening pipe 200, so that the corresponding position on the ecological bag forms a hole for sowing, and the plant seeds to be sown can be scattered into the hole for sowing, and the soil originally in the ecological bag is taken out from the opening pipe 200 to cover the plant seeds in the hole for sowing, thus the sowing of the plant seeds is completed.

[0020] In the present embodiment, when the soil originally in the ecological bag is taken out from the opening pipe 200, the user can hold the handle 100 and drive the opening end 210 of the opening pipe 200 to repeatedly impact the force receiving surface (such as the ground, the wall surface and the table surface, etc.), through the vibration of the opening pipe 200 in the process of repeated impact, the soil originally in the ecological bag is finally separated from the opening pipe 200; the user can also insert a rod structure, a spoon structure, etc. into the opening pipe 200 from the opening port 211, and take out the soil originally in the ecological bag from the opening pipe 200 through the actions of continuous insertion and pulling out, digging, etc. In addition, it should be noted that although Figure 1 the cross-sectional shape of the opening pipe 200 in the present embodiment is rectangular, those skilled in the art should know that Figure 1As an example, the cross-sectional shape of the actual opening tube 200 can also be any shape commonly known in the art, such as circular, oval, triangular, trapezoidal, polygonal, etc., and the same applies to the cross-sectional shape of the handle 100, which is not uniquely limited by the present application. It should be noted that the axis of the handle 100 and the axis of the opening tube 200 can be perpendicular to each other or intersect with each other, but in order to ensure better transmission of the force applied by the user, the two are preferably perpendicular to each other, and the handle 100 is arranged on the middle region of the outer wall of the opening tube 200.

[0021] It can be understood that when the hole is opened, the outer edge of the opening port 211 cuts the non-woven fabric of the ecological bag and makes the opening end 210 enter the non-woven fabric, which is a knife-cut type opening, which has the following advantages: the opening process does not squeeze the soil around the hole as in the traditional scheme, that is, the soil in the ecological bag becomes more compact, which is beneficial to the penetration and storage of rainwater or maintenance water to the soil around the hole after sowing, which can effectively and continuously provide water for the germination of plant seeds, and ensure the root growth after the germination of plant seeds; the hollow opening end 210 (i.e. having a communication opening port 211 inside the opening tube 200) can cut the non-woven fabric around the whole circumference, and the non-woven fabric in the opening area will not be partially connected to the periphery as in the traditional scheme, that is, it will not be suspended and covered on the hole, which ensures the emergence of the plant seeds after germination; the opening process can directly remove the soil in the ecological bag, and the removed soil in the ecological bag can be used to cover the plant seeds after sowing, without the need for additional soil removal or carrying soil to cover the plant seeds, thereby improving the efficiency of the sowing operation. As can be seen, for plant seeds sown by using ecological bags, the sowing hole opening tool of the present application not only improves the survival rate of plant seeds and reduces growth obstacles, but also improves the efficiency of the sowing operation.

[0022] In some embodiments, still referring to Figure 1 , the central axis of the opening port 211 intersects with the axis of the opening tube 200, and the acute angle formed by the intersection of the central axis of the opening port 211 and the axis of the opening tube 200 is greater than 0° and less than 90°, such as 30° and 45°, etc., preferably 45°; that is, the opening end 210 (equivalent to the opening port 211) of the opening tube 200 is inclined, which makes the opening end 210 of the opening tube 200 more easily cut the non-woven fabric of the ecological bag around the whole circumference, and can avoid that part of the non-woven fabric is suspended and covered on the hole. Of course, in other embodiments, the opening end 210 (equivalent to the opening port 211) of the opening tube 200 can also be designed to be straight, that is, the central axis of the opening port 211 coincides with the axis of the opening tube 200. Whether the opening end 210 (equivalent to the opening port 211) of the opening tube 200 is inclined or straight can be selected according to actual needs, which is not uniquely limited by the present application.

[0023] In some embodiments, the outer edge of the opening port 211 has a blade structure (not shown in the figure) extending from the outer wall of the opening tube 200 into the opening port 211 and gradually thinning in thickness, that is, the outer edge of the opening port 211 is actually a ring-shaped blade, which can be achieved by cutting or grinding the outer edge of the opening port 211, which makes the process of cutting the ecological bag with the opening end 210 of the opening tube 200 more labor-saving and easier to cut the non-woven fabric of the ecological bag along the entire circumference. Of course, in other embodiments, the blade structure can also extend from the outer wall of the opening tube 200 to the outside of the opening port 211 (i.e., extend in a trumpet shape) and gradually thin in thickness, and can also extend along the axis direction of the opening tube 200 and gradually thin in thickness. It should be noted that the direction in which the blade structure extends from the outer wall of the opening tube 200 can be selected according to actual needs, and the present application does not make a unique limitation on this. Preferably, the blade structure is sawtooth-shaped or wavy-shaped to further improve the labor-saving degree in the process of cutting the ecological bag with the opening end 210 of the opening tube 200.

[0024] In some embodiments, Figure 2 The structure of the hole-digging hole opening tool is shown in another perspective view. In addition to the opening end 210, the opening tube 200 also has a soil taking end 220 opposite the opening end 210, and the soil taking end 220 has a soil taking port 221 connected to the inside of the opening tube 200, that is, the opening tube 200 has a through hole along its axis direction, and the two openings opposite to each other are the opening port 211 and the soil taking port 221. In the actual process of digging the hole, when the soil originally in the ecological bag is taken out of the opening tube 200, the user can insert a rod-like structure into the opening tube 200 from the opening port 211, and by moving the rod-like structure in the opening tube 200 along the axis direction of the opening tube 200, the soil originally in the ecological bag is pushed from the opening end 210 of the opening tube 200 to the soil taking end 220, and then pushed out from the soil taking port 221 of the opening tube 200, so that the soil can be taken out of the opening tube 200 by repeatedly impacting the force surface or continuously plugging, digging, and other actions when the opening tube 200 only has the opening port 211, thereby shortening the time of taking soil out of the opening tube 200 and improving the efficiency of digging the hole.

[0025] As one of the embodiments, the caliber of the opening port 211 is smaller than that of the soil taking port 221, that is, the opening port 211 belongs to a small port and the soil taking port 221 belongs to a large port, or in other words, the opening end 210 of the opening tube 200 is relatively thin, and the soil taking end 220 of the opening tube 200 is relatively thick. In the actual opening process of the dibble hole, the user holds the handle 100 and drives the opening end 210 of the opening tube 200 to penetrate into the ecological bag, and the soil in the ecological bag enters the opening tube 200 through the opening port 211, and because the opening end 210 of the opening tube 200 is relatively thin and the soil taking end 220 is relatively thick, the soil entering the opening tube 200 through the opening port 211 will be squeezed to the relatively thick soil taking end 220, and then the user can invert the opening tube 200 after pulling it out of the ecological bag, that is, the soil taking port 221 is directed towards the ground, at this time the soil in the soil taking end 220 will fall from the larger soil taking port 221 due to the action of gravity, thereby achieving the taking of the soil originally located in the ecological bag from the opening tube 200; it can be understood that this process does not need to repeatedly impact the stress surface, nor does it need to rely on rod structures, spoon structures and the like, and can further shorten the time for taking soil from the opening tube 200 and further improve the opening efficiency of the dibble hole.

[0026] Exemplarily, for the soil taking end 220 of the opening tube 200, it is cut along the axial direction of the opening tube 200, and its cross section is a trapezoid, the upper base (short) of the trapezoid is close to the handle 100, and the lower base (long) of the trapezoid is away from the handle 100 (the lower base is the soil taking port 221), and for the part of the opening tube 200 located between the upper base of the trapezoid and the opening port 211, the inner diameter remains the same, so as to realize that the caliber of the opening port 211 is smaller than that of the soil taking port 221. Alternatively, the opening tube 200 is a tapered tube, which gradually thins in the direction from the soil taking port 221 to the opening port 211, so as to realize that the caliber of the opening port 211 is smaller than that of the soil taking port 221. In addition, it should be noted that the shape of the opening end 210 and the soil taking end 220 (or the shape of the opening tube 200) can be designed according to actual needs, as long as the caliber of the opening port 211 is smaller than that of the soil taking port 221, and the present application does not make a unique limitation.

[0027] In some embodiments, in order to increase the weight of the perforating pipe 200 to facilitate the perforating operation, the length of the perforating pipe 200 is generally longer, and then in order to limit the depth of the perforating pipe 200 penetrating into the ecological bag (i.e. the depth of the hole for sowing), a limiting structure (not shown in the figure) can be arranged on the outer wall of the perforating pipe 200, and the limiting structure is located between the perforating end 210 and the handle 100. In the actual process of opening the hole for sowing, when the user holds the handle 100 and drives the perforating end 210 of the perforating pipe 200 to penetrate into the ecological bag, the part of the perforating pipe 200 between the limiting structure and the perforating port 211 will penetrate into the ecological bag, and the side of the limiting structure close to the perforating port 211 will abut against the outer surface of the ecological bag, thereby limiting the depth of the perforating pipe 200 penetrating into the ecological bag, that is, the maximum depth of the perforating pipe 200 penetrating into the ecological bag is the length of the part of the perforating pipe 200 between the limiting structure and the perforating port 211. It can be understood that through the arrangement of the limiting structure, the depth of the hole for sowing is controlled, avoiding the disadvantages of too shallow or too deep perforation in the traditional scheme, and improving the emergence rate of plant seeds.

[0028] Exemplarily, the limiting structure includes a protrusion extending outward from the outer wall of the perforating pipe 200; or, the limiting structure includes a plurality of protrusions extending outward from the outer wall of the perforating pipe 200 and spaced around the perforating pipe 200; or, the limiting structure includes a ring-shaped protrusion extending outward from the outer wall of the perforating pipe 200 and surrounding the perforating pipe 200. It should be noted that the specific form of the limiting structure can be designed according to actual needs, as long as it can play a limiting role, and the present application does not make a unique limitation thereto.

[0029] In some embodiments, the outer wall of the opening pipe 200 is provided with a plurality of limiting hole groups, each of which includes at least one limiting hole, and the plurality of limiting hole groups are located between the opening end 210 and the handle 100 and are spaced along the axis direction of the opening pipe 200. Each limiting hole group is used for inserting a limiting piece group, and each limiting piece group includes at least one limiting piece. In the actual opening process of the sowing hole, the user can first insert the limiting piece group in a certain limiting hole group, and then hold the handle 100 and drive the opening end 210 of the opening pipe 200 to penetrate into the ecological bag. At this time, the part of the opening pipe 200 between the limiting piece group and the opening port 211 will penetrate into the ecological bag, and the side of the limiting piece group close to the opening port 211 will abut against the outer surface of the ecological bag, thereby limiting the depth of the opening pipe 200 penetrating into the ecological bag. That is, the maximum depth of the opening pipe 200 penetrating into the ecological bag is the length of the part of the opening pipe 200 between the limiting piece group and the opening port 211. It can be understood that, since the outer wall of the opening pipe 200 is provided with a plurality of limiting hole groups located between the opening end 210 and the handle 100 and spaced along the axis direction of the opening pipe 200, the user can insert the limiting piece group in different limiting hole groups according to different depths of the sowing hole. That is, one opening pipe 200 can adapt to multiple different sowing hole depths, and the depth of the sowing hole can be adjusted at any time. Therefore, through the arrangement of the plurality of limiting hole groups and the plurality of limiting piece groups, the opening depth of the sowing hole can be controlled, and the opening depth of the sowing hole can be adjusted at any time, thereby avoiding the disadvantages of too shallow or too deep opening in the traditional scheme, and improving the emergence rate of plant seeds.

[0030] For example, the limiting piece group includes any one of a single limiting plate, a single limiting rod, and a single limiting pin; or, the limiting piece group includes any one of a plurality of limiting plates, a plurality of limiting rods, and a plurality of limiting pins which are spaced around the opening pipe 200; or, the limiting piece group includes a ring-shaped limiting plate or a ring-shaped limiting rod which surrounds the opening pipe 200. It should be noted that the specific form of the limiting piece group can be designed according to actual needs, as long as it can play a limiting role, and the present application does not make a unique limitation thereon. Of course, no matter what form the limiting piece group adopts, the limiting hole group needs to be adapted thereto.

[0031] The above embodiments are only preferred implementations of the present application, and are not the only limitations of the point-planting hole opening tool. Based on the above embodiments, those skilled in the art can make flexible settings according to actual application scenarios. It can be understood that, by implementing the above embodiments of the present application, the handle 100 and the hollow opening pipe 200 form the point-planting hole opening tool, one end of the handle 100 is arranged on the outer wall of the opening pipe 200, the opening pipe 200 has an opening end 210, and the opening end 210 has an opening port 211 that is in communication with the inside of the opening pipe 200. In the actual opening process of the point-planting hole, the handle 100 can drive the opening pipe 200 to move towards the surface of the ecological bag under the action of an external force (i.e., under the manipulation of the user), so that the opening end 210 penetrates into the ecological bag, and the soil in the ecological bag is collected in the opening pipe 200 through the opening port 211, and then the user can pull out the opening pipe 200 from the ecological bag through the handle 100, so as to take out the soil in the ecological bag in the form of being collected in the opening pipe 200, and the position of the soil in the ecological bag taken out by the opening pipe 200 forms the point-planting hole. As can be seen, when the point-planting hole is opened, the present application uses the outer edge of the opening port 211 to cut the non-woven fabric of the ecological bag and make the opening end 210 enter the non-woven fabric, which belongs to a knife-cut type opening, and has the following advantages: the opening process does not squeeze the soil around the hole like the traditional scheme, i.e., does not make the soil in the ecological bag more compact, is beneficial to the penetration and storage of rainwater or maintenance watering to the soil around the hole after the point-planting, can effectively and continuously provide water for the germination of the plant seeds, and ensures the root growth after the germination of the plant seeds; the hollow opening end 210 (having the opening port 211 in communication with the inside of the opening pipe 200) can cut the non-woven fabric around the whole length, the non-woven fabric in the opening area is not connected to the periphery like the traditional scheme, i.e., does not suspend and cover the hole, ensures the emergence of the plant seeds after germination; the opening process can directly take out the soil in the ecological bag, and the soil taken out from the ecological bag can be used to cover the plant seeds after the point-planting of the plant seeds, without the need to take additional soil or carry the soil to cover the plant seeds, thereby improving the efficiency of the point-planting operation. In short, for the plant seeds planted by using the ecological bag, the point-planting hole opening tool of the present application not only can improve the survival rate of the plant seeds and reduce the growth obstacles, but also can improve the efficiency of the point-planting operation.

[0032] It should be noted that the present application is described in a progressive manner in the several embodiments shown above, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
