Description

TECHNICAL FIELD

[0001] The utility model relates to weeding equipment technical field, concretely relates to a weeder. BACKGROUND

[0002] The daily work of garden maintenance includes maintaining the flower bed beside the road, since the flower bed is the main body of urban greening, so the actual maintenance process generally includes daily fertilization, pruning, pest control and weeding of the planted plants. The weeding work is relatively simple, since the flower bed is often maintained daily, so the plants in the flower bed are still mainly the planted plants, and the number of weeds accounts for a relatively small proportion in all plants, so in the daily weeding work, the adjacent distance of weeds is relatively far, and the staff needs to constantly squat and stand up to pull weeds or remove weeds, which is labor-intensive. Moreover, the pulled weeds are easy to break roots, leading to weed regrowth; if tools such as hoes and shovels are used for weeding, although they can remove part of the weeds on the ground to some extent, the use of the tools reduces the operation space, especially the use of hoes, so the green plants are easily damaged when using this type of tool. At the same time, due to the limited operation space, the weeds are easy to regrow during the weeding process.

[0003] In view of the above situation, the patent with publication number CN 216017613 U discloses a hand-held Spartina alterniflora pulling-out auxiliary tool, which is convenient to use and can quickly and efficiently pull out Spartina alterniflora. It mainly relies on a cylindrical root cutter to cut off the roots and rhizomes of the soil and weeds. When the external root cutter is inserted into the soil, the soil remover automatically rises, and when the root cutter is pulled out, the user can step on the upper protruding structure of the soil remover with one foot, so that the soil is left in place while the external root cutter is pulled out. However, the structure adopts a cylindrical design, although the soil column in the root cutter is pushed out by the soil remover, the soil remover can only push the top of the soil column, and if the soil is relatively sticky, it is also easy to block in the root cutter. The root cutter is cylindrical, so soil blocks are inevitably adhered to the inner wall of the root cutter during long-term use, which not only affects subsequent use, but also increases the weight of the entire tool.

Specific embodiments

[0025] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the following is in connection with the drawings and embodiment, and the utility model is further explained in detail. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0026] Refer to Figures 1 to 4The shown weeding device comprises a sleeve 10, a driving rod 20 and a weeding head 30, the outer wall of one end of the sleeve 10 is provided with a foot pedal 11; the driving rod 20 is movably inserted into the sleeve 10, the end of the driving rod 20 away from the foot pedal 11 is provided with a locking mechanism, the locking mechanism can relatively lock the relative displacement of the driving rod 20 and the sleeve 10; the weeding head 30 is installed on the end of the driving rod 20 located at the foot pedal 11, one end of the weeding head 30 is provided with a wedge-shaped tip 31, a containing groove 32 is opened on one side of the wedge-shaped tip 31 along the length direction.

[0027] The weeding head 30 and the driving rod 20 are designed separately, so that the user can select different types of weeding heads 30 according to the use requirements. In addition, the purpose of the locking mechanism is to facilitate the user to insert the weeding head 30 into the soil when applying force to the sleeve 10 through the foot pedal 11. The main body of the weeding head 30 in this application is also cylindrical, and the wedge-shaped tip 31 can actually be regarded as a structure obtained by cutting the entire weeding head 30 along the non-radial direction. The containing groove 32 can be coaxially arranged with the weeding head 30 in actual use, or it can be a wedge-shaped groove structure, which is used according to the actual use requirements.

[0028] It should be noted that in actual use, when it is necessary to pull up weeds from the soil layer, the user needs to continue to step on the foot pedal 11 at this time, the lower end of the sleeve 10 needs to press the soil layer, and then the user needs to lift the driving rod 20 upward to drive the wedge-shaped tip 31 to pull out the weeds and the soil from the soil layer. Therefore, the function of the sleeve 10 is mainly to avoid bringing the surrounding soil when the wedge-shaped tip 31 is pulled out of the soil layer, to ensure the stability and beauty of the entire soil layer, to reduce the impact on the surrounding green plants, and to be especially suitable for use in grasslands.

[0029] The weeding device uses the sleeve 10 as the main body for holding and supporting, and uses the locking mechanism to relatively lock the relative displacement of the driving rod 20 and the sleeve 10, which is beneficial for the user to drive the entire sleeve 10 to the ground through the foot pedal 11, and then to insert the weeding head 30 into the soil through the driving rod 20, the entire structure is simple and convenient to force. Moreover, the tip of the weeding head 30 is wedge-shaped, so the stress area is small, which is conducive to insertion in a narrow space; the wedge-shaped surface of the wedge-shaped tip 31 can loosen the soil when inserted into the soil. The containing groove 32 opened on the wedge-shaped tip 31 can not only have the ability to pry the soil, but also can accommodate weeds together with the surrounding soil, and the two sides of the wedge-shaped tip 31 can also cut the weed roots, which is conducive to the user to pull up the weeds and the attached soil.

[0030] Referring toFigure 1 In the present application, since the accommodation groove 32 in the wedge-shaped tip 31 has a certain degree of inclination, and most of the area is designed in an open manner, it is difficult to bring up the weeds and the adhered soil column. In the process of pulling out the weeds and the adhered soil column from the wedge-shaped tip 31, the weeds and the adhered soil column are easily separated from the wedge-shaped tip 31 itself, so in an embodiment of the present application, a plurality of reverse teeth are arranged in the accommodation groove 32. By using the design of the reverse teeth, the wedge-shaped tip 31 can facilitate the lifting of the soil to a certain extent.

[0031] Referring to Figure 2 and Figure 3 In an embodiment of the present application, in order to facilitate disassembly and maintenance, the end of the weeding head 30 away from the wedge-shaped tip 31 is provided with a connecting portion 33, the connecting portion 33 is provided with a limiting protrusion 34, the corresponding end of the driving rod 20 is provided with a insertion slot 21 matched with the connecting portion 33, the insertion slot 21 is provided with a clamping groove 22 matched with the limiting protrusion 34, and the weeding head 30 and the driving rod 20 can rotate synchronously. In this way, the weeding head 30 can be driven by the driving rod 20 to rotate around the center of the accommodation groove 32 or the rotation center self-constructed, which is beneficial to cut the soil around the weeds, thereby cutting off the root system of the weeds, and facilitating the pulling out of the weeds.

[0032] In some embodiments, one end of the accommodation groove 32 penetrates through the wedge-shaped tip 31 and is opened into the connecting portion 33, and forms a cylindrical structure. Of course, the side wall of the cylindrical area is not closed, and the side wall is also provided with an opening slot in the length direction. Such a structure design can accommodate the top of the soil column, and is beneficial to process the difficult soil column and the weeds together.

[0033] Further, in order to facilitate insertion into the soil layer, and cut off the rhizome of the weeds or surrounding green plants, the wedge-shaped tip 31 is provided with a cutting portion on both sides of the accommodation groove 32, and the cutting portion is provided with a blade or a blade tooth.

[0034] In some improved embodiments, in order to avoid that the side wall of the soil column is adsorbed in the accommodation groove 32 due to adhesion, at least one air hole 35 is arranged on the back of the wedge-shaped tip 31, which can reduce the adhesion of the soil block in the accommodation groove 32 to a certain extent.

[0035] Further, the end of the driving rod 20 close to the locking mechanism is provided with a handle 26, and the user can drive the driving rod 20 and the weeding head 30 to rotate together by using the handle 26.

[0036] Referring to Figures 1 to 3In an embodiment of the present application, in order to enable relative locking of the sleeve 10 and the driving rod 20 and relative movement of the two when required, the locking mechanism comprises a spring 23 and a limiting pin head 24, the outer wall of the corresponding region of the driving rod 20 is provided with a mounting clamping hole 25 in the radial direction, the spring 23 is mounted in the mounting clamping hole 25, the limiting pin head 24 is movably inserted into the mounting clamping hole 25, one end of the spring 23 abuts against the bottom of the mounting clamping hole 25, and the other end is connected to the corresponding end of the limiting pin head 24, and the sleeve 10 is provided with a limiting hole 12 matched with the limiting pin head 24. When the limiting pin head 24 is clamped into the limiting hole 12, the sleeve 10 and the driving rod 20 are in a relative locking state, and at this time, the driving rod 20 and the weeding head 30 can be moved together by applying force through the foot pedal 11. By pressing the end of the limiting pin head 24, the limiting pin head 24 is pulled out of the limiting hole 12, and at this time, the relative movement of the driving rod 20 and the sleeve 10 can be realized, that is, the driving rod 20 can be used to pull out weeds.

[0037] In the improved embodiment, in order to prevent the driving rod 20 from being pulled out of the sleeve 10, the end of the sleeve 10 away from the foot pedal 11 is provided with a mounting ring seat 13, and the driving rod 20 is coaxially mounted in the mounting ring seat 13 and can rotate relative to the mounting ring seat 13. The mounting ring seat 13 prevents excessive friction between the driving rod 20 and the inner wall of the sleeve 10, which is beneficial to the worker to pull out weeds with the driving rod 20.

[0038] Further, in some improved embodiments, in order to facilitate the worker to hold the sleeve 10 and fix it, the outer wall of the end of the sleeve 10 away from the foot pedal 11 is provided with a holding sleeve.

[0039] Again referring to Figure 3 Since the wedge-shaped tip 31 is a wedge-shaped structure, during insertion into the soil layer, the exposed plant roots on the surface of the soil layer may be deformed to both sides or extruded to both sides by the wedge-shaped tip 31. These exposed roots will affect the driving rod 20 to pull out the soil column and weeds from the soil layer later. Therefore, in an improved embodiment of the present application, the end of the sleeve 10 away from the foot pedal 11 forms an insertion cutting cylinder 14, and the port of the insertion cutting cylinder 14 is provided with a plurality of cutting teeth 15. The inner diameter of the insertion cutting cylinder 14 is greater than the outer diameter of the wedge-shaped tip 31 or even greater than the outer diameter of the weeding head 30. Therefore, the insertion cutting cylinder 14 can not only cut the exposed plant roots, but also expand and extrude the area around the soil column, which is convenient for the user to pull up the soil column.

[0040] The above-mentioned embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
