Description

Technical Field

[0001] This utility model relates to the field of weeding tools, and in particular to an agricultural weeding tool. Background Technology

[0002] A weed puller is a tool that allows a person to pull weeds upright. A weed puller generally consists of a long metal tube with claws at the end. Inside the tube is a push rod that controls the opening and closing of the claws. By inserting the open claws into the soil, then closing them to grip the roots of the weeds, the tube is pulled upwards, allowing for weed removal without bending over. Examples of existing weed pullers include:

[0003] The weed puller with publication number CN202587904U includes multiple grass-grabbing claws that are hinged by pins. Its claw head structure is relatively complex, which not only makes assembly inconvenient, but also makes the pins and grass-grabbing claws prone to bending and breaking when the grass-grabbing claws are obstructed from inserting into the soil, resulting in an unstable claw head structure.

[0004] The weed puller with publication number CN103583091A has its claw nail top set inside the claw nail hole of the support plate, which is also inconvenient to assemble. At the same time, when the claw nail is obstructed when inserted into the soil, the claw nail still has the defect of being easy to bend and break.

[0005] Therefore, the structure of the weed puller needs to be improved. Utility Model Content

[0006] In view of this, the present invention proposes an agricultural weeding tool, aiming to solve the problems of unstable claw structure and inconvenient assembly in existing weeding tools.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] refer to Figure 1-5 An embodiment of this utility model shows an agricultural weed puller, including a main body 1, a limiting plate 2, multiple claw nails 4, a push plate 5, and a push rod 6;

[0042] The main body 1 is in the shape of a hollow rod, and a pressure plate 11 is provided at the bottom end of the main body 1. A foot pedal 12 is also provided on the main body 1. Preferably, in order to make the structure stable, the main body 1, the pressure plate 11 and the foot pedal 12 are integrated metal parts in this embodiment.

[0043] The limiting plate 2 is fixedly disposed below the pressure plate 11, and a cavity 3 is formed between the pressure plate 11 and the limiting plate 2. The limiting plate 2 is provided with a first central hole 21 and a plurality of first through holes 22 arranged circumferentially around a central axis P. A protrusion 41 extends from the side of the top end of the claw nail 4, and the claw nail 4 passes through the first through hole 22 of the limiting plate 2, and the protrusion 41 is located in the cavity 3. The push plate 5 is movably disposed below the limiting plate 2, and the push plate 5 is provided with a plurality of second through holes 52 arranged circumferentially around the central axis P, and the claw nail 4 passes through the second through holes 52. The distance between the second through hole 52 and the central axis P is L2, and the distance between the first through hole 22 and the central axis P is L1, and the distance L2 is less than the distance L1. The push rod 6 is disposed inside the main body 1, and the push rod 6 slides through the first central hole 21 and is connected to the push plate 5.

[0044] Specifically, by pushing and pulling the push rod 6, the push rod 6 causes the push plate 5 to move axially along the central axis P. The second through hole 52 on the push rod 6 adjusts the inclination of the claw nail 4. Figure 5 As shown, since L2 is smaller than L1, when the push rod 6 moves upward, the multiple claw nails 4 will close; when the push rod 6 moves downward, the multiple claw nails 4 will open. Correspondingly, when weeding, first open the multiple claw nails 4, then step on the foot pedal 12 to insert the multiple claw nails 4 into the soil, with the claw nails 4 positioned around the perimeter of the grass; then close the multiple claw nails 4, which will grip the roots of the grass. At this point, pull the main body 1 upward to remove the grass.

[0045] During the above process, when the claw nail 4 is inserted into the soil, the top of the claw nail 4 will abut against the bottom of the bearing plate 11, and the bearing plate 11 will support the claw nail 4. The protrusion 41 on the claw nail 4 can strengthen the strength of the top of the claw nail 4, facilitate the contact with the bearing plate 11 to transmit pressure, and prevent the claw nail 4 from bending and breaking easily.

[0046] This agricultural weeder forms a claw head structure at the bottom of the main body 1 through a pressure plate 11, a limiting plate 2, claw nails 4, and a push plate 5. Without using a pin for hinge, the limiting plate 2 limits the claw nails 4, allowing the claw nails 4 to stably open and close. The pressure plate 11 supports the top of the claw nails 4, making it easy to exert force when the claw nails 4 are obstructed when inserted into the soil. The top of the claw nails 4 is provided with a protrusion 41. The claw nails 4 are sequentially inserted through the first through hole 22 of the limiting plate 2 and the second through hole 52 of the push plate 5, making positioning quick and assembly simple.

[0047] In some embodiments, for further convenience of assembly / disassembly, such as Figure 3 and Figure 4As shown, the pressure plate 11 has multiple first connecting holes 111, and the limiting plate 2 has second connecting holes 23 corresponding to the positions of the first connecting holes 111. A sleeve 7 is provided in the cavity 3, with one end of the sleeve 7 abutting against the pressure plate 11 and the other end abutting against the limiting plate 2. Set bolts 8 are sequentially inserted into the first connecting holes 111, the sleeve 7, and the second connecting holes 23, and set nuts 9 are threaded onto the set bolts 8. The sleeve 7 ensures that a cavity 3 of a certain height is formed between the pressure plate 11 and the limiting plate 2 to accommodate the protrusion 41 of the claw nail 4. It should be noted that the protrusion 41 is provided at the top of the claw nail 4 so that the top of the claw nail 4 cannot pass through the first through hole 22 of the limiting plate 2. The protrusion 41 should be able to swing within the cavity 3 to accommodate the opening and closing action of the claw nail 4. Therefore, as... Figure 5 As shown, the height of the cavity 3 should be slightly larger than the height of the protrusion 41.

[0048] In some embodiments, the body 1 is internally provided with an elastic element (not shown) for driving the push rod 6 to move away from the claw nails 4. In application, the elastic element keeps the multiple claw nails 4 closed. Before insertion into the soil, the push rod 6 should be pushed first, causing the push plate 5 to drive the multiple claw nails 4 to open, then the claw nails 4 are inserted into the soil, and finally the push rod 6 is pulled to close the multiple claw nails 4 again. The structure for the push rod 6 to drive the push plate 5 can be found in prior art CN103583091A. Furthermore, to facilitate pushing and pulling the push rod 6, such as... Figure 2 As shown, the top end of the push rod 6 protrudes from the main body 1, and a pressing head 63 is provided at the top end of the push rod 6. Thus, the push rod 6 can be pushed or pulled through the pressing head 63.

[0049] In some embodiments, to further prevent the claw pin 4 from bending or breaking, such as Figure 3 As shown, the claw nail 4 is a metal sheet with a thickness of d, which is not less than 5mm; in order to reduce the resistance of the claw nail 4 when it is inserted into the soil, the bottom end of the claw nail 4 is formed with an acute-angled insertion part 42.

[0050] Preferably, to improve the stability of the claw nail 4 in gripping the roots of the grass, such as Figure 3 As shown, the claw nail 4 has a locking tooth 43 on the side near the central axis P.

[0051] In some embodiments, to facilitate the connection between the push rod 6 and the push plate 5, such as Figure 5As shown, the push plate 5 is provided with a second central hole 51, the push rod 6 passes through the second central hole 51, and the push rod 6 is threaded with a first locking nut 61 and a second locking nut 62. The first locking nut 61 and the second locking nut 62 are respectively clamped on both sides of the push plate 5.

[0052] In some embodiments, to facilitate gripping the main body 1 so as to perform insertion and removal actions on the main body 1, such as... Figure 2 As shown, the main body 1 is equipped with a gripping rod. Thus, by holding the gripping rod 13, the main body 1 can be pushed downward to insert the claw nail 4 into the soil; or the main body 1 can be pulled upward to pull the claw nail 4 out of the soil.

[0053] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
