Description

Technical Field

[0001] This utility model belongs to the field of agricultural tool technology, and in particular relates to a multifunctional sickle. Background Technology

[0002] The sickle is a traditional agricultural tool mainly used for harvesting crops such as wheat and rice. A typical sickle consists of two main parts: a blade and a handle. The blade, which is curved and is the core of the sickle, is held by the handle to drive the blade in the cutting process.

[0003] In existing technologies, knife handles are mostly designed as retractable structures that can store the blade. This design effectively prevents the blade from rusting due to prolonged exposure to air, and also prevents accidental cuts to the user, improving the safety of sickle use. Furthermore, the retractable design expands the sickle's working range and increases its flexibility. However, when the blade is stored inside the handle, the lack of an effective locking mechanism allows it to rotate freely. This not only makes the blade prone to accidental detachment during transportation, posing a safety hazard, but also makes it easy for the blade to come into contact with the handle when stored, leading to blade wear or handle damage, severely impacting the product's lifespan.

[0004] Therefore, there is an urgent need for a multi-functional sickle to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-functional sickle that improves the stability of the blade when it is stored, ensures the safety of the blade when it is stored, and effectively avoids the collision between the blade and the handle, while ensuring the working range of the sickle and its storage function.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A multi-functional sickle is provided, including a handle and a blade that are rotatably connected. The handle is provided with a storage groove and the length of the handle is adjustable. The blade has a storage state where it is stored in the storage groove and a use state where it is detached from the storage groove. The multi-functional sickle also includes a number of elastic limiting components disposed in the storage groove. Each elastic limiting component includes an elastic element and a limiting element. One end of the elastic element is connected to the groove wall of the storage groove, and the other end is connected to the limiting element.

[0008] When the blade switches from the use state to the storage state, the blade gradually contacts and presses against the limiting member; the elastic limiting component is set on one side of the storage groove along the thickness direction of the blade. In the storage state, the limiting member contacts the blade under the elastic force of the elastic member and presses the blade against the groove wall of the storage groove. Alternatively, elastic limiting components are set on both sides of the storage groove along the thickness of the blade. In the storage state, the limiting member contacts the blade under the elastic force of the elastic member, and the blade is clamped by the limiting components on both sides.

[0009] Optionally, the limiting element includes a flexible limiting seat and a limiting rod. One end of the limiting rod is connected to the elastic element, and the other end is connected to the flexible limiting seat. In the retracted state, the flexible limiting seat is in contact with the blade.

[0010] Optionally, the elastic limiting component also includes telescopic components symmetrically arranged on both sides of the elastic component. One end of the telescopic component is connected to the wall of the storage groove, and the other end is connected to the limiting component. When the blade switches between the use state and the storage state, the telescopic component extends or retracts.

[0011] Optionally, the multi-functional sickle also includes an anti-slip pad located in the storage compartment, which contacts the blade when stored.

[0012] Optionally, the tool holder is provided with a protective component that is movable along its axial direction or its circumference. The protective component has a blocking position for blocking the opening of the storage slot and an unblocking position for unblocking the opening of the storage slot. When in the unblocking position, the blade can switch between the use state and the storage state.

[0013] Optionally, the tool holder is equipped with an alarm operating component and an alarm, the alarm operating component is electrically connected to the alarm, and the alarm operating component is configured to control the opening and closing of the alarm;

[0014] And / or, the multi-functional sickle also includes a lighting element, which is movably mounted on the handle.

[0015] Optionally, the multi-functional sickle also includes a rotating shaft that passes through the handle and the blade along the thickness direction of the blade and rotates in conjunction with the handle.

[0016] Optionally, the end of the rotating shaft is provided with an anti-disengagement part that is detachably connected to it, and the anti-disengagement part can contact the outer wall of the handle.

[0017] Optionally, the knife handle includes a first connecting handle and a second connecting handle, the blade is rotatably disposed at the end of the first connecting handle away from the second connecting handle, a storage slot is disposed on the first connecting handle, and the overlap length between the first connecting handle and the second connecting handle is adjustable.

[0018] Optionally, one of the first connecting handle and the second connecting handle is provided with a connecting groove extending along the extension direction of the tool holder, and the other of the first connecting handle and the second connecting handle can extend into the connecting groove and slide or thread it into the groove wall.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model provides a multifunctional sickle. In use, the blade is outside the storage slot during harvesting, and the elastic element does not deform. When the blade is not in use, rotating the blade relative to the handle switches it from the use state to the storage state. During this process, the blade gradually enters the storage slot and contacts the limiting element inside the slot. The blade presses against the limiting element, causing the elastic element to deform. Simultaneously, the limiting element experiences a spring force opposite to the direction of compression. Thus, after the blade switches to the storage state, the spring force of the elastic element drives the limiting element to contact the blade. When several elastic elements are arranged on one side of the storage slot, the blade in the storage state can be pressed against the slot wall by the limiting elements, making the blade stably and securely stored in the storage slot. When elastic limiting components are arranged on both sides of the blade thickness inside the storage slot, the blade in the storage state can be clamped by the limiting elements on both sides, achieving stable storage of the blade in the storage state. Regardless of how the various elastic limiting components are arranged in the storage slot, the stability of the blade in the stored state can be guaranteed. This not only effectively avoids the automatic switching of the blade state and ensures the safety of the blade during storage, but also effectively prevents the blade from colliding with the storage slot wall, thus improving the service life of the blade and the handle.

Therefore, they should not be construed as limitations on this utility model.

[0035] It should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 3 As shown, this embodiment provides a multi-functional sickle that, while ensuring the sickle's working range and storage function, improves the stability of the blade 2 when stored, ensures the safety of the blade 2 when stored, and effectively avoids collisions between the blade 2 and the handle 1.

[0038] See Figure 1 , Figure 2 and Figure 3The multi-functional sickle includes a handle 1 and a blade 2 rotatably connected. The handle 1 has a storage groove 111, and the length of the handle 1 is adjustable. The blade 2 has a stored state where it is stored in the storage groove 111 and a used state where it is detached from the storage groove 111. The multi-functional sickle also includes several elastic limiting components 3 disposed in the storage groove 111. Each elastic limiting component 3 includes an elastic element 31 and a limiting element 32. One end of the elastic element 31 is connected to the groove wall of the storage groove 111, and the other end is connected to the limiting element 32. When the blade 2 switches from the used state to the stored state, the blade 2 gradually contacts and presses against the limiting element 32. The elastic limiting components 3 are disposed in the storage groove 111 along the thickness direction of the blade 2. Figure 2 In the storage state, the limiting member 32 contacts the blade 2 under the elastic force of the elastic member 31, and presses the blade 2 against the groove wall of the storage groove 111. Alternatively, elastic limiting components 3 are provided on both sides of the thickness of the blade 2 in the storage groove 111. In the storage state, the limiting member 32 contacts the blade 2 under the elastic force of the elastic member 31, and the blade 2 is clamped by the limiting members 32 on both sides.

[0039] In the multi-functional sickle provided in this embodiment, when in use, the blade 2 is located outside the storage slot 111 for harvesting operations, and the elastic element 31 does not deform. When the blade 2 is not needed, the blade 2 can be switched from the use state to the storage state by rotating it relative to the handle 1. During this process, the blade 2 gradually enters the storage slot 111 and contacts the limiting element 32 in the storage slot 111. The blade 2 will squeeze the limiting element 32, and the elastic element 31 will deform. At the same time, the limiting element 32 will be subjected to a spring force in the opposite direction to the direction of the squeeze. Thus, after the blade 2 is switched to the storage state, the spring force of the elastic element 31 can drive the limiting element 32 to contact the blade 2. When several elastic members 31 are all arranged on one side of the storage groove 111, the blade 2 in the stored state can be pressed against the groove wall of the storage groove 111 under the action of the limiting member 32, so that the blade 2 is stably and firmly stored in the storage groove 111. When elastic limiting members 3 are arranged on both sides of the thickness of the blade 2 in the storage groove 111, the blade 2 in the stored state can be clamped by the limiting members 32 on both sides, realizing the stable storage of the blade 2 in the stored state. No matter how the several elastic limiting members 3 are arranged in the storage groove 111, the stability of the blade 2 in the stored state can be guaranteed. This not only effectively avoids the automatic switching of the blade 2 state and ensures the safety of the blade 2 when stored, but also effectively avoids the blade 2 from colliding with the groove wall of the storage groove 111, thus improving the service life of the blade 2 and the handle 1.

[0040] Specifically, the blade 2 is rotatably connected to the handle 1, which supports the blade 2, allowing workers to operate the blade 2 for harvesting by gripping the handle 1. Furthermore, the handle 1 provides space for storing the blade 2, enabling the multi-functional sickle to have a storage function without the need for additional parts. Adjusting the length of the handle 1 ensures the range of the blade 2 that can be harvested when the user grips the handle 1, guaranteeing the flexibility of using the multi-functional sickle.

[0041] For example, the handle 1 is made of aluminum alloy, which is lightweight, corrosion-resistant and high-strength, so that the handle 1 can have sufficient support force, while also reducing the weight of the handle 1, ensuring the user's comfort when using it.

[0042] For example, see Figure 1 The curved shape of the blade 2 not only optimizes the contact angle between its cutting edge and the cutting surface during cutting, reducing resistance and making the cutting smoother, but also allows the blade 2 to cover a larger cutting area when rotating or moving, thereby improving cutting efficiency.

[0043] In this embodiment, see Figure 1 , Figure 2 and Figure 3 The storage groove 111 is provided with elastic limiting components 3 on both sides along the thickness direction of the blade 2, and several elastic limiting components 3 are provided on each side; in other embodiments, several elastic limiting components 3 are provided on one side of the storage groove 111 along the thickness direction of the blade 2. When in the storage position, the limiting member 32 presses the blade 2 against the groove wall of the storage groove 111 on the side without elastic limiting components 3 along the thickness direction of the blade 2.

[0044] For example, see Figure 3 The elastic element 31 is a spring.

[0045] Optionally, see Figure 1 and Figure 3 The limiting member 32 includes a flexible limiting seat 321 and a limiting rod 322. One end of the limiting rod 322 is connected to the elastic member 31, and the other end is connected to the flexible limiting seat 321. In the retracted state, the flexible limiting seat 321 contacts the blade 2. The flexible limiting seat 321 is flexible, so when the blade 2 contacts the flexible limiting seat 321, the flexible limiting seat 321 can deform. This not only allows the flexible limiting member 32 to accommodate blades 2 of different thicknesses, thus expanding the versatility of the elastic limiting component 3 while ensuring the limiting effect, but also effectively prevents the blade edge of the blade 2 from being damaged by impact when the flexible limiting member 32 contacts the blade 2, ensuring the service life of the blade 2. The limiting rod 322 can constrain the direction of movement of the flexible limiting seat 321, ensuring that the flexible limiting seat 321 contacts the blade 2 along the deformation direction of the elastic member 31.

[0046] For example, the flexible limiting member 32 is made of spring steel or rubber.

[0047] In this embodiment, see Figure 1 and Figure 3 The flexible limiting seat 321 is curved, and when retracted, both ends of the flexible limiting seat 321 are in contact with the blade 2. This arrangement can more evenly distribute the elastic force received by the elastic member 31 from the flexible limiting seat 321, avoiding excessive local stress on the flexible limiting seat 321 and the blade 2, which could cause damage. In other embodiments, the flexible limiting member 32 is a flat plate structure.

[0048] Optionally, see Figure 1 and Figure 3 The elastic limiting component 3 also includes telescopic members 33 symmetrically arranged on both sides of the elastic member 31. One end of the telescopic member 33 is connected to the wall of the storage groove 111, and the other end is connected to the limiting member 32. When the blade 2 switches between the use state and the storage state, the telescopic member 33 extends or shortens. The arrangement of the telescopic members 33 on both sides can stably support the limiting member 32 and ensure that the limiting member 32 can only move along the thickness direction of the blade 2 under the elastic force of the elastic member 31, so as to avoid bending or damage to the limiting member 32.

[0049] Specifically, see Figure 1 and Figure 3 When the blade 2 switches from the use state to the storage state, the limiting member 32 is squeezed and the telescopic member 33 is shortened; when the blade 2 switches from the storage state to the use state, the blade 2 gradually relaxes the squeezing of the limiting member 32 and the telescopic member 33 extends.

[0050] In this embodiment, see Figure 1 and Figure 3 The flexible limiting seat 321 is curved in an arc shape. One end of the telescopic member 33 is rotatably connected to the wall of the receiving groove 111, and the other end is rotatably connected to the side of the flexible limiting seat 321 opposite to the blade 2. During the movement of the curved flexible limiting seat 321, the telescopic member 33 will rotate relative to the flexible limiting seat 321 and the wall of the receiving groove 111 to match the shape of the flexible limiting seat 321. In other embodiments, the flexible limiting member 32 is a flat plate structure, and the telescopic member 33 extends along the thickness direction of the blade 2 and is fixedly connected to both the wall of the receiving groove 111 and the flexible limiting seat 321.

[0051] For example, the telescopic member 33 is a telescopic rod.

[0052] Optionally, see Figure 1 and Figure 2The multi-functional sickle also includes an anti-slip pad 4 set in the storage slot 111. When stored, the anti-slip pad 4 contacts the blade 2, which can increase the friction force on the blade 2 in the storage slot 111 and effectively improve the stability of the blade 2 when stored in the storage slot 111.

[0053] In this embodiment, see Figure 1 and Figure 2 Anti-slip pads 4 are provided on both sides of the storage groove 111 along the thickness direction of the blade 2, which further increases the friction between the anti-slip pads 4 and the blade 2, and improves the limiting effect of the blade 2 in the storage groove 111 when stored.

[0054] For example, the anti-slip mat 4 is made of rubber.

[0055] Optionally, see Figure 1 and Figure 2 The tool holder 1 is provided with a axial direction ( Figure 2 A protective member 5 is movable in the Y direction or along its circumference. The protective member 5 has a blocking position for blocking the opening of the storage slot 111 and an unblocking position for unblocking the opening of the storage slot 111. In the unblocking position, the blade 2 can switch between the use state and the storage state. In the blocking position, the opening of the storage slot 111 is blocked by the protective member 5, which can effectively prevent dust or debris from entering the storage slot 111 and thus prevent damage to the blade 2. The protective member 5 can unblock the storage slot 111 by moving it on the handle 1, so that the blade 2 can enter or leave the storage slot 111, thus avoiding affecting the storage function of the multi-functional sickle.

[0056] Specifically, see Figure 1 The tool holder 1 is provided with a slide rail 112 extending along its axial or circumferential direction, and the protective member 5 is provided with a slider (not shown in the figure) that slides in cooperation with the slide rail 112, thereby enabling the protective member 5 to move on the tool holder 1. The slide rail 112 can constrain the movement path of the protective member 5 and ensure that the protective member 5 can move smoothly on the tool holder 1.

[0057] For example, protective component 5 is a cover or a plate. See also Figure 1 The slide rail 112 extends along the axial direction of the tool holder 1.

[0058] In an optional embodiment, see [link to relevant documentation] Figure 1 The tool holder 1 is equipped with an alarm operating component 61 and an alarm (not shown in the figure). The alarm operating component 61 is electrically connected to the alarm and is configured to control the activation and deactivation of the alarm. When the user encounters danger while working in the field, the alarm can be activated by operating the alarm operating component 61. The alarm can then emit an alarm signal, enabling the user to be rescued in a timely manner and providing a safety guarantee for the user's work in the field.

[0059] For example, see Figure 1 The alarm operation component 61 is a button, and the alarm is a buzzer.

[0060] In this embodiment, see Figure 1 The handle 1 is equipped with a detachable anti-touch cover 62. When the anti-touch cover 62 is connected to the handle 1, it covers the alarm operating component 61. This not only effectively prevents the user from accidentally activating the alarm operating component 61 while using the multi-functional sickle, but also prevents the alarm operating component 61 from being corroded by moisture due to long-term exposure to air, which would reduce its sensitivity and affect the alarm effect. When the anti-touch cover 62 is detached from the handle 1, the user can operate the alarm operating component 61.

[0061] For example, the handle 1 is provided with a slot, and the anti-collision cover 62 can be engaged or disengaged from the slot.

[0062] In other embodiments, see Figure 1 The knife handle 1 is provided with an anti-touch cover 62 that is rotatably connected to it. The anti-touch cover 62 has a protective position that covers the alarm operating element 61 and an operating position that is partially separated from the knife handle 1. In the protective position, the anti-touch cover 62 can protect the alarm operating element 61 from accidental touch and damage; in the operating position, an opening is formed between the anti-touch cover 62 and the knife handle 1, through which the user can operate the alarm operating element 61.

[0063] In another alternative embodiment, see [link to relevant documentation]. Figure 1 The multi-functional sickle also includes a lighting element 71, which is movably mounted on the handle 1. The lighting element 71 provides a light source for the user, enabling the multi-functional sickle to be used at night or in low-light environments, thus expanding its functionality and applicability. The movable mounting of the lighting element 71 on the handle 1 allows the user to adjust the direction of the light according to specific circumstances, further enhancing the versatility of the multi-functional sickle.

[0064] In this embodiment, see Figure 1 The tool holder 1 is provided with a mounting base 121 that can be rotated around its extension direction. The lighting element 71 is provided on the mounting base 121. The direction of illumination of the lighting element 71 can be changed by rotating the mounting base 121.

[0065] For example, the lighting element 71 is an arc-shaped light strip or a light bulb.

[0066] Specifically, the end of the tool holder 1 away from the blade 2 is provided with a rotating groove, and the mounting base 121 is inserted into the rotating groove and is rotatably connected to the groove wall through a bearing.

[0067] Further, see Figure 1The tool holder 1 is also provided with a lighting operation component 72 that is electrically connected to the lighting component 71. The lighting operation component 72 is configured to control the opening and closing of the lighting component 71.

[0068] In another alternative embodiment, see [link to relevant documentation]. Figure 1 The tool holder 1 is equipped with an alarm operation component 61 and an alarm device, as well as a lighting component 71.

[0069] In this embodiment, see Figure 1 and Figure 2 The multi-functional sickle also includes a battery 81 located on the handle 1. The battery 81 is electrically connected to the lighting component 71 and the alarm, and is used to power the lighting component 71 and the alarm, ensuring that the lighting component 71 and the alarm can be used normally in the field.

[0070] Optionally, see Figure 1 and Figure 2 The multi-functional sickle also includes a rotating shaft 9, which passes through the handle 1 and the blade 2 along the thickness direction of the blade 2 and is rotatably engaged with the handle 1. When the blade 2 is driven to rotate, the blade 2 drives the rotating shaft 9 to rotate relative to the handle 1, thereby realizing the rotatable connection between the handle 1 and the blade 2.

[0071] In this embodiment, see Figure 1 and Figure 2 The end of the rotating shaft 9 is provided with an anti-detachment part 91 that is detachably connected to it. The anti-detachment part 91 can contact the outer wall of the handle 1 to prevent the rotating shaft 9 from detaching from the handle 1 and the blade 2 during use, thus ensuring the safety of the blade 2 during use. When the blade 2 needs to be replaced, the anti-detachment part 91 is removed from the rotating shaft 9, and the rotating shaft 9 can be separated from the handle 1 and the blade 2. At this time, the blade 2 can be separated from the handle 1 and replaced.

[0072] For example, the anti-detachment part 91 is engaged with the rotating shaft 9. The rotating shaft 9 has a slot, and the anti-detachment part 91 includes a insertion rod and a connecting part. The insertion rod is engaged in the slot, and the connecting part contacts the handle 1. In other embodiments, the anti-detachment part 91 is threadedly connected to the rotating shaft 9. The rotating shaft 9 has an external thread, and the anti-detachment part 91 has a threaded hole. The end of the rotating shaft 9 is located within the threaded hole and is threadedly connected to the anti-detachment part 91 through the external thread and the internal thread of the threaded hole.

[0073] Optionally, see Figure 1 and Figure 2 The knife handle 1 includes a first connecting handle 11 and a second connecting handle 12. The blade 2 is rotatably disposed at the end of the first connecting handle 11 away from the second connecting handle 12. A storage groove 111 is disposed on the first connecting handle 11, and the overlap length between the first connecting handle 11 and the second connecting handle 12 is adjustable. The length of the knife handle 1 can be adjusted by adjusting the overlap length between the first connecting handle 11 and the second connecting handle 12.

[0074] Specifically, see Figure 1 One of the first connecting handle 11 and the second connecting handle 12 is provided with a connecting groove extending along the extension direction of the tool holder 1. The other of the first connecting handle 11 and the second connecting handle 12 can be inserted into the connecting groove and slidably or threadedly connected to the groove wall, thereby realizing the adjustment of the overlap length between the first connecting handle 11 and the second connecting handle 12.

[0075] In this embodiment, see Figure 2 The connecting groove is provided on the second connecting handle 12, and the end of the first connecting handle 11 away from the blade 2 can extend into the connecting groove and slide to connect with the connecting groove.

[0076] Further, see Figure 1 The second connecting handle 12 is provided with a plurality of connecting holes arranged at intervals along its axial direction, and the first connecting handle 11 is provided with a plurality of through holes arranged at intervals along its axial direction. The tool holder 1 also includes a fastener 13. After the overlap length of the first connecting handle 11 and the second connecting handle 12 is the required length, the fastener 13 is passed through the through hole and fastened in the connecting hole to fix the overlap length of the first connecting handle 11 and the second connecting handle 12.

[0077] For example, fastener 13 is a bolt, and fastener 13 is threadedly connected to the connecting hole.

[0078] In other embodiments, a connecting groove is provided on the second connecting handle 12, and an internal thread is provided on the groove wall. The first connecting handle 11 includes a screw portion provided with an external thread. The screw portion can extend into the connecting groove and is threadedly connected to the first connecting handle 11 through the external thread and the internal thread.

[0079] Optionally, see Figure 1 and Figure 2 The multi-functional sickle also includes a controller 82 mounted on the handle 1 and a sensor 51 mounted on the protective member 5. The controller 82 is electrically connected to the sensor 51, battery 81, lighting element 71, and alarm. The battery 81 powers the controller 82. The sensor 51 monitors the distance between the blade 2 and the protective member 5, as well as the position of the protective member 5. The controller 82 controls the activation and deactivation of the battery 81, lighting element 71, and alarm. When the sensor 51 detects that the distance between the blade 2 and the protective member 5 is decreasing while the protective member 5 remains in a blocked position, the controller 82 will activate the alarm or lighting element 71 to remind the user to move the protective member 5 or the blade 2 as soon as possible, ensuring safety during use.

[0080] The above description is only a specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model fall within the protection and disclosure scope of the present utility model.
