Description

Technical Field

[0001] This utility model belongs to the field of grape branch cleaning technology, and more specifically, it relates to a grape branch forking structure for use on a shovel. Background Technology

[0002] Currently, clearing and pruning grapevines is a laborious task in grape cultivation management. To facilitate the collection and transport of these vines, workers usually attach a detachable fork to their shovels for picking up the vines. When shoveling is required, the fork is removed, making the shovel versatile.

[0003] In existing technology, such forks are typically fixed by a mounting bracket welded to the back of the shovel plate. While this method achieves the function of mounting the forks, it has significant drawbacks in practical use. Because the mounting bracket is directly welded to the back of the shovel plate, it forms a protruding structure on the surface of the shovel plate. Even after the forks are removed, this protrusion remains, causing the mounting bracket to come into direct contact with the soil when the shovel is used for shoveling. This severely hinders the shovel plate from cutting smoothly into the soil and affects the smoothness and efficiency of shoveling. Utility Model Content

[0004] This utility model provides a grape branch forking structure for use on a shovel. By setting the mounting sleeve and slide rail on the shovel handle, the front of the shovel plate can remain absolutely smooth and flat during shoveling operations, thereby ensuring smooth and unobstructed cutting into the soil and ultimate efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a structure for forking grape branches on a shovel is provided, including a mounting sleeve, a slide rail, a slide bar, and a fork. The mounting sleeve is fixedly fitted onto the outer periphery of the shovel handle; the slide rail is disposed on the outer periphery of the mounting sleeve and extends along an axis perpendicular to the mounting sleeve; the slide bar is slidably connected to the slide rail and is locked by a locking member; the fork is connected to the slide bar and is located on the back of the shovel plate.

[0006] In one possible implementation, the slide rail has a first groove extending along the direction of the slide rail on the side away from the mounting sleeve, and a second groove extending along the direction of the slide rail is provided through the end face of the slide rail. The second groove is located on one side of the first groove and communicates with the first groove. The slide bar includes a first sliding part that is slidably connected to the first groove and a second sliding part that is slidably connected to the second groove.

[0007] In some embodiments, the locking member is disposed on the side of the slide rail away from the mounting sleeve and is threadedly connected to the slide rail. The locking member extends into the second slide groove and abuts against the second sliding part.

[0008] In some embodiments, the side of the second sliding portion opposite to the mounting sleeve is provided with a receiving groove for accommodating the inner end of the locking member.

[0009] In some embodiments, the outer end of the locking member is provided with a force-applying platform.

[0010] In one possible implementation, a first connecting sleeve is provided on the outer peripheral wall of the mounting sleeve, and a second connecting sleeve is provided on the outer peripheral wall of the shovel magazine, which is disposed opposite to the first connecting sleeve. The first connecting sleeve and the second connecting sleeve are connected by a connector.

[0011] In some embodiments, the connector includes a bolt and a nut, the bolt being inserted into a first connecting sleeve and a second connecting sleeve; the nut is threadedly connected to the bolt, and the head of the bolt and the nut are located at opposite ends of the first connecting sleeve and the second connecting sleeve, respectively.

[0012] In some embodiments, a positioning groove is provided on the end face of the first connecting sleeve away from the second connecting sleeve, and a positioning post is provided on the bolt to engage with the positioning groove.

[0013] In one possible implementation, the mounting sleeve is connected to the shovel handle by screws.

[0014] In some embodiments, a plurality of screws are spaced apart circumferentially on the mounting sleeve.

[0015] The grape vine forking structure provided in this embodiment, compared with the prior art, cleverly moves the mounting base from the back of the shovel to the shovel handle, i.e., the mounting sleeve and slide rail installation method, so that the front of the shovel can remain absolutely smooth and flat during shoveling operations, thereby ensuring smooth and unobstructed cutting into the soil and ultimate efficiency.

[0021] Please see Figures 1 to 3 The present invention provides a grape vine forking structure for use on a shovel. The shovel includes a shovel plate 1 and a shovel handle 2. The shovel plate 1 is connected to the shovel handle 2 via a shovel magazine 3. The grape vine forking structure includes a mounting sleeve 10, a slide rail 20, a sliding strip 30, and a fork 50. The mounting sleeve 10 is fixedly fitted onto the outer periphery of the shovel handle 2. The slide rail 20 is disposed on the outer periphery of the mounting sleeve 10 and extends along an axial direction perpendicular to the mounting sleeve 10. The sliding strip 30 is slidably connected to the slide rail 20 and locked by a locking member 40. The fork 50 is connected to the sliding strip 30 and located on the back of the shovel plate 1.

[0022] This application provides a grape branch forking structure for use on a shovel. In actual use, when fruit growers need to collect pruned branches in the vineyard, they simply slide the slider 30 connected to the fork 50 along the slide rail 20 on the outer periphery of the mounting sleeve 10 until the fork 50 moves and is positioned in the optimal working position on the back of the shovel plate 1. Then, the slider 30 is locked tightly using the locking member 40. At this point, the shovel is successfully transformed into an efficient forking tool. Users can use the fork 50 to pick up, lift, and move bundles of branches, just like using a pitchfork. When the branch collection task is completed and the shovel's soil-shoveling function needs to be restored, the operation is extremely simple. Just loosen the locking member 40 and slide the slider 30 together with the fork 50 along the slide rail 20 away from the back area of ​​the shovel plate 1, so that it no longer obstructs the shovel plate 1. The shovel instantly returns to its original state and can be used for digging and shoveling without any hindrance.

[0023] By cleverly moving the mounting base from the back of the shovel plate 1 to the shovel handle 2 and giving the fork a 50° movable characteristic, the front of the shovel plate 1 can remain absolutely smooth and flat during shoveling operations, thus ensuring smooth and efficient cutting into the soil. At the same time, this design allows for seamless and rapid switching between the forking and shoveling modes, truly achieving multi-purpose functionality and greatly improving the tool's ease of use and overall efficiency in agricultural work. Its structure, fixed to the more robust shovel handle 2, provides more stable support than welding it to the thinner shovel plate 1, making it safer and more reliable when lifting heavy objects.

[0024] The grape vine forking structure provided in this embodiment, compared with the prior art, cleverly moves the mounting base from the back of the shovel plate 1 to the shovel handle 2, that is, the mounting sleeve 10 and the slide rail 20 installation method, so that the front of the shovel plate 1 can remain absolutely smooth and flat during shoveling operations, thereby ensuring that the shovel cuts into the soil smoothly and efficiently.

[0025] In one possible implementation, the aforementioned slide rail 20 adopts the following... Figures 1 to 3 The structure shown is described in the following document. Figures 1 to 3 The slide rail 20 has a first slide groove 21 extending along the direction of the slide rail 20 on the side opposite to the mounting sleeve 10. The end face of the slide rail 20 has a second slide groove 22 extending along the direction of the slide rail 20. The second slide groove 22 is located on one side of the first slide groove 21 and communicates with the first slide groove 21. The slide bar 30 includes a first sliding part 31 that is slidably connected to the first slide groove 21 and a second sliding part 32 that is slidably connected to the second slide groove 22.

[0026] Specifically, in use, the user installs the slider 30 by inserting the first sliding part 31 into the first groove 21 on the back of the slide rail 20 from the end of the slide rail 20, while the second sliding part 32 is inserted into the second groove 22, which facilitates the stable installation of the slider 30.

[0027] The precise fit between the double grooves and the double sliding parts forms an extremely stable sliding pair system. It can effectively resist the lateral force and torque generated when picking up branches, and completely prevent the slide bar 30 from shaking, jamming or even derailing when under force, thus ensuring the stability of the picking operation.

[0028] In some embodiments, see Figure 2 and Figure 3 The locking member 40 is disposed on the side of the slide rail 20 away from the mounting sleeve 10 and is threadedly connected to the slide rail 20. The locking member 40 extends into the second slide groove 22 and abuts against the second sliding part 32.

[0029] Specifically, once the slider 30 has moved to the desired position, the user simply tightens the locking member 40, which is threadedly connected to the slide rail 20, so that its inner end directly abuts against the surface of the second sliding portion 32 located within the second slide groove 22. By applying strong positive pressure, a large static friction force is generated on the surface of the second sliding portion 32, thereby firmly fixing the slider 30 in its current position, sufficient to withstand various impacts generated when dragging or forking branches in uneven fields. Moreover, this design, which integrates the locking mechanism into the slide rail 20, not only protects the locking member 40 itself from accidental damage by external forces, but also makes the overall appearance more concise and streamlined.

[0030] In some embodiments, see Figure 2 The second sliding part 32 has a receiving groove 321 on the side opposite to the mounting sleeve 10 for accommodating the inner end of the locking member 40.

[0031] Specifically, a receiving groove 321 is added to the side of the second sliding part 32 opposite to the mounting sleeve 10. When the user tightens the locking member 40, its inner end will eventually embed into this pre-set receiving groove 321. The beneficial effect of this is far greater than that of simple surface contact friction locking. The end of the locking member 40 is wrapped by the receiving groove 321, which greatly enhances the shear resistance, making it difficult for the slider 30 to shift even when subjected to huge longitudinal or lateral loads, thus improving the reliability and safety of the anti-loosening mechanism.

[0032] In some embodiments, see Figure 2 The outer end of the locking element 40 is provided with a force application platform 41.

[0033] Specifically, a force-applying platform 41 is provided at its outer end, for example, it can be designed as a wing nut 82 or have a thick handle for easy hand tightening. When using it, the user does not need to find and use additional tools such as screwdrivers or wrenches; the entire tightening and loosening operation can be completed easily and quickly with just the strength of the fingers.

[0034] In one possible implementation, the aforementioned mounting sleeve 10 adopts the following... Figure 1 and Figure 2 The structure shown is described in the following document. Figure 1 and Figure 2 The outer peripheral wall of the mounting sleeve 10 is provided with a first connecting sleeve 70, and the outer peripheral wall of the shovel magazine 3 is provided with a second connecting sleeve 71 opposite to the first connecting sleeve 70. The first connecting sleeve 70 and the second connecting sleeve 71 are connected by a connector 80.

[0035] Specifically, during installation, the user needs to precisely align the first connecting sleeve 70, which is located on the outer peripheral wall of the mounting sleeve 10, with the second connecting sleeve 71, which is fixed on the outer peripheral wall of the shovel magazine 3, and then rigidly connect the two together using an independent connector 80. Through this connection, most of the torque and load generated when forking branches is directly transmitted and distributed to the extremely strong shovel magazine 3 and shovel handle 2, rather than relying solely on the friction between the mounting sleeve 10 and the shovel handle 2. This fundamentally prevents the mounting sleeve 10 from loosening, slipping, or rotating around the shovel handle 2 under long-term heavy-duty use, ensuring unparalleled stability and durability of the entire forking structure.

[0036] In some embodiments, see Figure 1 and Figure 2 The connector 80 includes a bolt 81 and a nut 82. The bolt 81 is inserted into the first connecting sleeve 70 and the second connecting sleeve 71. The nut 82 is threadedly connected to the bolt 81. The head of the bolt 81 and the nut 82 are located at opposite ends of the first connecting sleeve 70 and the second connecting sleeve 71, respectively.

[0037] Specifically, during installation, the user simply passes the bolt 81 through the aligned first connecting sleeve 70 and second connecting sleeve 71, and then tightens the nut 82 at the other end. The advantage of this method is that the bolt 81 and nut 82, as a mature, reliable, and cost-effective fastening method, can generate a large preload by tightening the nut 82, ensuring a tight fit between the first connecting sleeve 70 and the second connecting sleeve 71, forming an extremely strong rigid connection. This structure is simple, has low manufacturing and maintenance costs, and its connection strength has been proven through long-term industrial practice, making it sufficient to withstand the harsh working conditions in agricultural operations.

[0038] In some embodiments, see Figure 2The first connecting sleeve 70 has a positioning groove 72 on its end face away from the second connecting sleeve 71, and the bolt 81 has a positioning post 83 that is inserted into the positioning groove 72.

[0039] Specifically, during assembly, the user needs to align and insert the locating pin 83 on the bolt 81 into the locating groove 72 before tightening the nut 82. This subtle step is highly practical, cleverly solving the common problem of the bolt 81 head potentially spinning freely when tightening the nut 82. The insertion and engagement of the locating pin 83 and the locating groove 72 effectively prevents the bolt 81 from rotating, allowing the user (especially when operating alone) to complete the tightening operation without any obstacles. There is no need to search for a second tool to secure the bolt 81 head, greatly simplifying the installation and disassembly process and improving the convenience and efficiency of assembly.

[0040] In one possible implementation, the aforementioned mounting sleeve 10 adopts the following... Figure 2 The structure shown is described in the following document. Figure 2 The mounting sleeve 10 is connected to the shovel handle 2 by screw 60.

[0041] Specifically, the user tightens the screw 60 that penetrates the wall of the mounting sleeve 10, and uses the threaded tip of the screw 60 to insert into the shovel handle 2 for connection and fixation. It provides great installation flexibility, and the user can complete the fixing or disassembly using a common screwdriver 60, adapting to shovel handles 2 of different diameters or shapes.

[0042] In some embodiments, see Figure 2 Screws 60 are spaced apart around the circumference of the mounting sleeve 10.

[0043] Specifically, multiple screws 60 are evenly distributed circumferentially to simultaneously lock the shovel handle 2 from multiple directions. This not only makes the fixation more secure and the force distribution more uniform, but also effectively prevents the mounting sleeve 10 from rotating circumferentially or sliding axially when subjected to alternating loads.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
