Description

Technical Field

[0001] The utility model relates to the technical field of weeding and loosening soil, in particular to a slope weeding and loosening soil device for urban greening. Background Art

[0002] On both sides of urban roads, in order to prevent soil erosion and beautify urban landscapes, slopes are often set up on both sides of the roads, and lawns are planted on the slopes. When developing and utilizing the slopes, it is necessary to remove the weeds on the slopes, loosen the soil, and then plant grass seeds. Because the planting area of ​​the slope is limited and the slope trend is inclined downward, it is expensive to use a large weeder, and it is not easy for a large weeder to move stably on the slope. Therefore, handheld weeders are generally used directly to clean the weeds. Commonly used handheld weeders mainly include a handheld pole, one end of which is connected to a saw blade through a motor drive. The saw blade rotates to cut the grass, and the battery carried on the user's back is used to power the weeder;

[0003] When weeding, traditional handheld weeders need to use a handheld pole to lift the saw blade for weeding. Using the handheld pole to support the saw blade for a long time is labor-intensive. In addition, traditional handheld weeders can only weed, and it is not easy to combine the weeding and loosening processes to improve the efficiency of weeding and loosening. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0024] See also Figure 1-4 In an embodiment of the utility model, a slope weeding and loosening device for urban greening includes an annular support block 100, a motor 110 is fixed inside the annular support block 100, a transmission shaft 200 is fixed at the output end of the motor 110, a circular panel 210 is fixed at the bottom end of the transmission shaft 200, a saw blade 211 is fixed on the bottom surface of the circular panel 210, a plurality of connecting rods 220 are evenly slidably sleeved on the outer side of the transmission shaft 200, a plurality of sleeves 221 are evenly inserted and fixed at the top of the connecting rods 220, and the sleeves 221 are fixed at equal intervals. A soil crushing column 300 is slidably inserted inside, a plurality of L-shaped seats 400 are fixed at equal angles on the outer ring of the annular support block 100 in a ring shape, a support rod 500 is rotatably connected to the top of the L-shaped seat 400, a universal wheel 510 is fixed to the bottom end of the support rod 500, two support seats 120 are fixed to the top surface of the annular support block 100, a hand-held tube 121 is rotatably connected between the two support seats 120, and an adjustment component 600 for adjusting the position of the universal wheel 510 is arranged between the hand-held tube 121 and the plurality of support rods 500.

[0025] Specifically, the support rod 500 can move on the slope with the saw blade 211 on the motor 110 through the universal wheel 510, so that the saw blade 211 can cut weeds at different positions. By inserting multiple soil crushing columns 300 on the saw blade 211, the soil crushing columns 300 are pre-adjusted to the bottom of the saw blade 211 and in contact with the soil. The rotation of the saw blade 211 drives the multiple soil crushing columns 300 to rotate to loosen the soil, thereby combining slope weeding with loosening the soil, which is beneficial to improving the efficiency of weeding and loosening the soil.

[0026] like Figure 4 As shown, in this embodiment, the bottom surface of the circular panel 210 is evenly penetrated with circular holes for the soil crushing column 300 to pass through, an extrusion spring 310 is fixed between the top surface of the soil crushing column 300 and the sleeve 221, and a protrusion 320 is evenly fixed at the bottom end of the soil crushing column 300. The extrusion spring 310 allows the soil crushing column 300 to be movably inserted into the sleeve 221, so that the bottom end of the soil crushing column 300 can be flexibly combined with the ground soil, and the protrusion 320 on the outside of the soil crushing column 300 improves the effect of crushing the soil.

[0027] like Figure 3As shown, in this embodiment, the outer side of the transmission shaft 200 is screwed together with a limit ring 230, and the bottom outer side of the limit ring 230 is rotatably sleeved with a rotating ring, and a connecting block for supporting the connecting rod 220 is fixed to the outer side of the rotating ring, and an L-shaped block 231 is fixed to the bottom surface of the connecting block, and the L-shaped block 231 is clamped in the middle position of multiple connecting rods 220.

[0028] In this embodiment, rotating the limit ring 230 can cause the L-shaped block 231 to move downward with the multiple connecting rods 220, and then cause the sleeve 221 to move downward with the soil crushing column 300, so as to facilitate the subsequent contact between the soil crushing column 300 and the soil. When the limit ring 230 is rotated and adjusted, the rotating ring rotates on the outside of the limit ring 230, so that the L-shaped block 231 will not rotate synchronously with the limit ring 230.

[0029] like Figure 1 As shown, in this embodiment, a rotating block 410 is fixed to the top of the L-shaped seat 400, and a connecting shaft 411 rotatably connected to the support rod 500 is fixed inside the rotating block 410. A torsion spring is arranged between the connecting shaft 411 and the support rod 500, and a fixed block 511 is fixed to the bottom end of the support rod 500. The bottom surface of the fixed block 511 is rotatably connected to the universal wheel 510. The torsion spring cooperates with the branch rope 610 to enable the support rod 500 to stably support the annular support block 100, wherein the elastic force of the torsion spring prompts the support rod 500 to rotate in a direction away from the L-shaped seat 400. Embodiment 2

[0030] On the basis of the first embodiment, the height of the annular support block 100 is flexibly adjusted to make the soil crushing column 300 contact the soil.

[0031] like Figure 5 As shown, in this embodiment, the adjustment component 600 includes a plurality of branch ropes 610 and a threaded rod 620, one end of the branch rope 610 passes through the L-shaped seat 400 and is fixedly connected to the support rod 500, a main rope 630 is fixed between the top ends of the plurality of branch ropes 610, one end of the main rope 630 facing away from the branch rope 610 is rotatably connected to the threaded rod 620, the threaded rod 620 is screwed together with the hand-held tube 121, and one end of the threaded rod 620 is rotatably plugged with a rotating shaft fixedly connected to the main rope 630.

[0032] In this embodiment, the main rope 630 extends through the hand-held tube 121 to the interior thereof and is fixedly connected to the threaded rod 620. The threaded rod 620 is rotated to adjust the main rope 630 to pull or release the branch rope 610, thereby causing the branch rope 610 to pull or release the support rod 500, thereby facilitating the support rod 500 to move closer to or away from the annular support block 100, thereby adjusting the distance between the annular support block 100 and the ground, and facilitating the soil crushing column 300 to contact the soil to achieve the effect of loosening the soil.

[0033] Working principle: the user holds the hand-held tube 121 to move the annular support block 100 with the device on the slope, the motor 110 drives the transmission shaft 200 to rotate and the saw blade 211 to weed. During the movement of the device, the universal wheel 510 on the ground of the support rod 500 rolls on the ground. When the ground after weeding needs to be loosened, the downward limit ring 230 is screwed in to make the multiple connecting rods 220 move downward with the sleeve 221, and the sleeve 221 moves downward with the soil crushing column 300 at its bottom, so that the multiple soil crushing columns 300 penetrate the circular panel 210 and extend to Under the saw blade 211, the motor 110 will rotate with the saw blade 211, causing the multiple soil crushing columns 300 to rotate around the transmission shaft 200 as the axis. The threaded rod 620 is rotated to make it screw and move into the hand-held tube 121, so that the multiple branch ropes 610 are released, and under the elastic force of the torsion spring, the multiple support rods 500 and the universal wheels 510 move away from the saw blade 211, so that the distance between the saw blade 211 and the ground becomes smaller, making it easier for the bottom end of the soil crushing column 300 to contact the soil, and the rotating soil crushing column 300 can crush and loosen the soil.

[0034] In the present invention, the existing technology can also be used to carry a battery on the user's back, and the battery power supply machine 110 is used to operate the power supply.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
