Description

Technical Field

[0001] This utility model relates to the technical field of lawn trimming equipment, and more specifically, to a lawn trimming device for landscaping. Background Technology

[0002] In existing standards for trimming lawn edges, the depth and width are generally 3-5 cm, cutting down to the roots of the lawn vegetation. In actual trimming, to ensure the lawn is cut evenly, workers use a rectangular stainless steel rod to compact the outer edge of the lawn before using a utility knife to make straight cuts along the inner edge of the rod.

[0003] The above-mentioned edge trimming work has the following problems: First, when trimming manually with a utility knife, due to the lack of constraints and intuitive numerical references, the actual trimmed dimensions have a large error compared to the depth and width data required in the lawn trimming standard, which cannot meet the needs of subsequent customized edging filler embedding; Second, the stability of the stainless steel rod cannot be guaranteed when manually pressing it down. During the trimming process, the stainless steel rod is prone to shaking, which affects the trimming effect. Utility Model Content

[0004] The purpose of this invention is to provide a lawn trimming device for landscaping. This device replaces the traditional manual trimming operation, provides better compaction of the lawn within the trimming area, and has higher stability. At the same time, it can precisely adjust the depth and width of the trimming according to the size of the customized edging filler, resulting in a better user experience and ensuring the trimming effect of the landscaping lawn.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A lawn trimming device for landscaping includes a pressure bar with a rectangular cross-section. A reference bar is provided on the outer side of the pressure bar, and the outer side of the reference bar rests against the inner side of the curb. A foot pedal is fixed at the center of the upper surface of the reference bar. Two parallel telescopic brackets are provided on both sides of the upper surface of the pressure bar. The telescopic sections of the telescopic brackets are fixed with grooves on their outer sides. The tops of the telescopic sections of the telescopic brackets are connected to the lower surface of a rectangular frame. Two horizontally parallel guide rods are provided in the hollow area inside the rectangular frame. A slider is slidably mounted on the guide rod. The slider has mounting shafts on both its front and rear sides. The mounting shaft on the front side is rotatably connected to a guide wheel via a rotating bearing seat, and the outer end of the mounting shaft on the front side is connected to a control lever facing forward. The mounting shaft on the rear side is fixed downward to a convex frame via a nut.

[0007] As a further optimization of this solution, the lower end of the convex frame is provided with a through groove, and a cutting disc is fixed inside the through groove by a fastener.

[0008] As a further optimization of this solution, the lower surface of the pressure bar is provided with several tapered inserts at equal intervals, and all of the tapered inserts are inserted into the soil of the lawn.

[0009] As a further optimization of this solution, through holes are machined on both sides of the reference rod, and connecting rods pass through the through holes. The rear ends of the connecting rods are welded and fixed to both ends of the front side of the pressure rod. Scale lines are machined on the rod body near the pressure rod, and the connecting rods are limited by locking bolts above the reference rod. Scale lines are machined on the outer side of the telescopic section near the non-telescopic section, and the telescopic bracket is limited by locking bolts on the outer side of the non-telescopic section.

[0010] As a further optimization of this solution, the slide groove is welded and fixed to the outside of the telescopic section of the telescopic bracket by a sleeve on the rear side. The slide groove has a groove inside, and the guide wheel slides left and right along the groove.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This invention incorporates a connecting rod and a reference rod structure with graduated lines, as well as a telescopic support structure with graduated lines. Landscaping personnel can observe the graduated lines to precisely adjust the width of the lawn edge to be cut by the pressure rod, and also precisely adjust the cutting depth of the cutting disc. This meets the standards for lawn edge cutting in landscaping. Based on the dimensions of the customized edging filler, the cutting depth and width can be precisely adjusted, resulting in a better user experience and ensuring effective lawn edge cutting.

[0013] This invention incorporates a reference rod structure with a foot pedal and a pressure rod structure with several tapered inserts on its lower surface. Landscaping personnel can place one foot on the foot pedal and insert the tapered inserts into the lawn soil, thereby improving the compaction stability of the pressure rod. This results in better compaction, higher stability, and improved accuracy in edge cutting. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] To address the issues that arise from the current practice of manually cutting edges with a utility knife, which lacks constraints and intuitive numerical references, resulting in significant discrepancies between the actual cut dimensions and the depth and width data required by the lawn edge cutting standard, thus failing to meet the needs of embedding custom-shaped edging fillers, and the inability to consistently guarantee the stability of the stainless steel rod when manually pressing it down during the edge cutting process, which in turn affects the edge cutting effect;

[0021] like Figure 1 and Figure 2 As shown, this application includes a pressure rod 1 with a rectangular cross-section. A reference rod 2 is provided on the outer side of the pressure rod 1. The outer side of the reference rod 2 rests against the inner side of the curb. A foot pedal 3 is fixed at the center of the upper surface of the reference rod 2. Two parallel telescopic brackets 4 are provided on both sides of the upper surface of the pressure rod 1. A sliding groove 5 is fixed on the outer side of the telescopic section of the telescopic bracket 4. The top of the telescopic section of the telescopic bracket 4 is connected to the lower surface of the rectangular frame 6. Two horizontal parallel guide rods 7 are provided in the hollow area inside the rectangular frame 6. A slider 12 is slidably mounted on the guide rod 7. The front and rear sides of the slider 12 are provided with mounting shafts facing outward. The mounting shaft 8 located on the front side is rotatably connected to a guide wheel 10 through a rotating bearing seat 9. The outer end of the mounting shaft 8 on the front side is connected to an operating lever 11 facing forward. The mounting shaft 8 located on the rear side is fixed downward to a convex frame 13 through a nut.

[0022] The lower end of the convex frame 13 has a through groove, and the cutter disc 15 is fixed inside the through groove by a fastener 14;

[0023] The lower surface of the pressure bar 1 is provided with several tapered insertion rods 16 at equal intervals, and all of the tapered insertion rods 16 are inserted into the soil of the lawn;

[0024] like Figure 3As shown, through holes are machined on both sides of the reference rod 2 and the connecting rod 17 passes through the through holes. The rear ends of the connecting rod 17 are welded and fixed to the two ends of the front side of the pressure rod 1. The rod body of the connecting rod 17 near the pressure rod 1 is machined with scale lines and the connecting rod 17 is limited by the locking bolt 18 above the reference rod 2.

[0025] like Figure 4 As shown, the telescopic bracket 4 has scale lines machined on the outer side of the telescopic section near the non-telescopic section. The telescopic bracket 4 is limited by the locking bolt 18 on the outer side of the non-telescopic section.

The guide wheel 10 slides left and right along the groove 19.

[0026] Specifically, the inner side of the foot pedal 3 is 10 centimeters away from the outer side of the pressure bar 1, which does not affect the adjustment of the width of the lawn to be cut when the pressure bar 1 is pressed down. In actual use, the landscaping personnel observe the scale line according to the actual customized cutting thickness and depth data of the lawn in a certain area, and adjust the locking bolts 18 on both sides above the reference bar 2 and the locking bolts 18 on the non-telescopic section of the telescopic bracket 4 respectively. On the one hand, the width of the lawn to be cut when the pressure bar 1 is pressed down is clearly adjusted, and on the other hand, the cutting depth of the cutter disc 15 is clearly adjusted to meet the cutting standards of the garden green lawn. According to the size of the customized edging filler, the cutting depth and width are adjusted more precisely.

[0027] Next, the outer side of the reference rod 2 is placed against the inner side of the curb, one foot is placed on the foot pedal 3, and several tapered rods 16 are inserted into the lawn soil to ensure the compaction stability of the pressure rod 1. The landscaping worker holds the control lever 11 with one hand and pushes the slider 12 back and forth along the guide rod 7, which drives the cutter disc 15 below to cut the lawn. During the process, the guide wheel 10 slides left and right along the groove 19 to further improve the stability and reliability of the cutter disc 15. After the cutting is completed, the pressure rod 1 is pulled out, and the lawn edges cut by several tapered rods 16 are thrown into the garbage cart to continue the lawn cutting work in the next area.
