Description

Technical Field

[0001] This utility model is a afforestation dotting device, belonging to the field of afforestation. Background Technology

[0002] A ring structure with multiple marking rods is used to mark planting points through the rotation of the ring. Specifically, several marking rods are evenly distributed along the circumference of the ring. As the ring rotates, the marking rods sequentially contact the ground, and the position where the lower end touches the ground forms the planting point. This design utilizes the regularity of mechanical transmission to ensure that the marking rods alternately touch the ground at fixed intervals, ensuring that the planting points are evenly distributed along a straight path. Compared to the traditional manual point-by-point marking method, this marking device improves marking efficiency and reduces the error in the distance between points through the coordinated movement of the ring and the marking rods, significantly improving the standardization and precision of afforestation operations.

[0003] When manually driving a ring structure with a dotting rod to roll along the ground for afforestation marking, the ring is prone to deviating from the intended straight line direction due to human factors such as the operator's walking trajectory and the evenness of force applied. This deviation can lead to uneven changes in the spacing between adjacent rows of planting marks. For example, planting marks designed to be spaced 2 meters apart under an ideal straight trajectory may actually be spaced 2.5 meters apart or 1.5 meters apart due to ring deviation. This affects the uniformity of seedling distribution, reduces the utilization rate of forest land resources, and may lead to differentiation in tree growth later due to uneven competition for light and nutrients, increasing forest tending costs. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a afforestation marking device to solve the problems mentioned in the background technology. This utility model can limit the movement trajectory of the ring and reduce the error caused by human operation on the spacing between adjacent rows of planting marking points.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a afforestation marking device, comprising a ring, wherein a handle is rotatably mounted concentrically with the ring at the center of the ring via a connector, one end of the handle extends to the outside of the ring, and a plurality of marking rods are equidistantly mounted in a ring on the annular side of the ring, wherein a first tip is mounted on the end of the marking rod away from the ring, and a detachable L-shaped rod is mounted on the end of the marking rod away from the ring, wherein the end of the L-shaped rod away from the marking rod is arranged parallel to the marking rod, and a second tip is mounted on the end of the L-shaped rod away from the marking rod.

[0006] Furthermore, the connector includes a central ring, with a central ring arranged concentrically with the ring at the center of the inner ring. One end of the handle passes through the central ring and slides in contact with the central ring. Limiting rings are provided on both sides of the central ring along the length of the handle. The limiting rings slide in contact with the central ring and are sleeved on the handle and fixedly connected to the handle. Multiple spokes are equidistantly installed in a ring on the annular side of the central ring. The spokes extend in the radial direction of the ring and are fixedly connected to the ring at the end away from the central ring. The multiple spokes and multiple dotting rods are arranged alternately.

[0007] Furthermore, the ring has multiple rectangular openings equidistantly spaced on its annular side, the marking rod has a rectangular cross-section, the L-shaped rod has a rectangular cross-section, the end of the marking rod away from the first tip passes through the rectangular opening, and a plurality of positioning screws for limiting the relative position of the marking rod and the ring are threaded to one side of the ring.

[0008] Furthermore, a rectangular frame is fixedly connected to one end of the L-shaped rod near the dotting rod. The rectangular frame is fitted onto the dotting rod, and a limiting screw for limiting the relative position of the rectangular frame and the dotting rod is threaded onto the side of the rectangular frame away from the L-shaped rod.

[0009] Furthermore, one side of the ring is provided with a plurality of through holes at equal intervals in a ring shape, and the plurality of through holes communicate with a plurality of rectangular openings. A first threaded sleeve is provided on the outside of the through holes and is arranged concentrically with the through holes. One end of the first threaded sleeve is connected and fixed to the ring, and the positioning screw is threadedly connected to the first threaded sleeve.

[0010] Furthermore, a second threaded sleeve is installed on the side of the rectangular frame facing away from the L-shaped rod, the limiting screw is threaded into the second threaded sleeve, and a through hole for the limiting screw to pass through the rectangular frame is provided at the position covered by the second threaded sleeve.

[0011] Furthermore, the side of the dotting rod facing the positioning screw is recessed to form a strip groove, the strip groove is arranged along the length direction of the dotting rod, and a rubber strip is glued into the strip groove, with one end of the positioning screw in contact with the rubber strip.

[0012] The beneficial effects of this utility model are:

[0013] 1. The first tip at the end of the dotting rod and the second tip at the end of the L-shaped rod form a "vertical + horizontal" double marking point. When the ring rolls, both the first and second tips are in contact with the ground. At this time, the dotting rod and the L-shaped rod work together to prevent the ring from shifting at an angle, so that the ring can move along a straight trajectory under human power. This limits the movement trajectory of the ring and reduces the error caused by human operation on the spacing between adjacent rows of planting marking points.

[0014] 2. Adjust the length of the marking rod within the ring along the rectangular opening, thereby lengthening or shortening the arc length between two adjacent first tips. Once the arc length between two adjacent first tips meets the spacing requirement between two adjacent planting marks, use the positioning screw to limit the relative position of the marking rod and the ring, thus adjusting the spacing between two adjacent planting marks as needed.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1 and Figure 2This utility model provides a technical solution: a afforestation marking device, including a ring 1, a central ring 3 arranged concentrically with the ring 1 at the center of the ring 1, a handle 15 with one end passing through the central ring 3 and slidingly contacting the central ring 3, a limiting ring 4 on both sides of the central ring 3 along the length of the handle 15, the limiting ring 4 slidingly contacting the central ring 3, the limiting ring 4 being sleeved on the handle 15 and connected and fixed to the handle 15, a plurality of spokes 2 are equidistantly installed on the annular side of the central ring 3, the spokes 2 are arranged extending in the radial direction of the ring 1, the end of the spoke 2 away from the central ring 3 is connected and fixed to the ring 1, the plurality of spokes 2 are alternately arranged with a plurality of marking rods 11, the spokes 2 serve to connect the ring 1 and the central ring 3, under the restriction of the limiting rings 4, the relative position of the handle 15 and the central ring 3 remains unchanged, the handle 15 provides a gripping carrier for pushing the ring 1 to move.

[0023] See Figure 1 and Figure 2 One end of the handle 15 extends to the outside of the ring 1. Multiple dotting rods 11 are installed in a ring at equal intervals on the annular side of the ring 1. A first tip 9 is installed at the end of the dotting rod 11 away from the ring 1. A detachable L-shaped rod 7 is installed at the end of the dotting rod 11 away from the ring 1. The end of the L-shaped rod 7 away from the dotting rod 11 is arranged parallel to the dotting rod 11. A second tip 8 is installed at the end of the L-shaped rod 7 away from the dotting rod 11. The first tip 9 at the end of the dotting rod 11 and the second tip 8 at the end of the L-shaped rod 7 form a "vertical + horizontal" double marking point. When the ring 1 rolls, both the first tip 9 and the second tip 8 are in contact with the ground. At this time, the dotting rod 11 and the L-shaped rod 7 work together to prevent the ring 1 from shifting at an angle, so that the ring 1 can move along a straight trajectory under human power. This limits the movement trajectory of the ring 1 and reduces the error caused by human operation on the spacing between adjacent rows of planting marking points.

[0024] See Figures 1-4The ring 1 has multiple rectangular openings 17 evenly spaced on its annular side. The marking rod 11 has a rectangular cross-section, and the L-shaped rod 7 has a rectangular cross-section. The end of the marking rod 11 away from the first tip 9 passes through the rectangular opening 17. Multiple positioning screws 5 are threaded to one side of the ring 1 to limit the relative position of the marking rod 11 and the ring 1. Multiple through holes 18 are equally spaced on one side of the ring 1, and the multiple through holes 18 communicate with the multiple rectangular openings 17. A first threaded sleeve 13 is provided on the outside of the through hole 18 and is arranged concentrically with the through hole 18. One end is connected and fixed to the ring 1, so that the positioning screw 5 is threaded into the first threaded sleeve 13. This allows the width of the ring 1 to be reduced while the positioning screw 5 is stably installed. The length of the dotting rod 11 within the ring 1 is adjusted along the rectangular opening 17, thereby increasing or decreasing the arc length between two adjacent first tips 9. When the arc length between two adjacent first tips 9 meets the spacing requirement of two adjacent planting marks, the relative position of the dotting rod 11 and the ring 1 can be limited by the positioning screw 5, thus allowing the spacing between two adjacent planting marks to be adjusted as needed.

[0025] See Figure 1 and Figure 2 A rectangular frame 10 is fixedly connected to one end of the L-shaped rod 7 near the dotting rod 11. The rectangular frame 10 is sleeved on the dotting rod 11. A limiting screw 6 for limiting the relative position of the rectangular frame 10 and the dotting rod 11 is threadedly connected to the side of the rectangular frame 10 away from the L-shaped rod 7. A second threaded sleeve 14 is installed on the side of the rectangular frame 10 away from the L-shaped rod 7. A through hole for the limiting screw 6 to pass through the rectangular frame 10 is opened at the position covered by the second threaded sleeve 14, so that the limiting screw 6 is threadedly connected in the second threaded sleeve 14, thereby reducing the wall thickness of the rectangular frame 10 while ensuring the stable installation of the limiting screw 6.

[0026] See Figures 1-3 The side of the dotting rod 11 facing the positioning screw 5 is recessed to form a strip groove 16. The strip groove 16 is arranged along the length of the dotting rod 11. A rubber strip 12 is glued inside the strip groove 16. When the positioning screw 5 is tightened, one end of the positioning screw 5 contacts the rubber strip 12, thereby improving the stability of the positioning screw 5 in limiting the relative position of the dotting rod 11 and the ring 1.
