Description

Technical Field

[0001] This utility model relates to the field of harvesting tools, and in particular to a fruit and vegetable harvesting knife. Background Technology

[0002] Fruit and vegetable harvesting is a crucial part of agricultural production, and its efficiency and quality directly impact economic benefits. Currently, orchard and field harvesting operations still rely heavily on traditional hand tools, such as ordinary pruning shears and knives, or are carried out by workers barehanded. These methods have many inherent drawbacks and fail to meet the demands of modern, efficient, safe, and humane agricultural production.

[0003] Specifically, existing technologies have at least the following shortcomings:

[0004] Poor ergonomics and easy operator fatigue: The grip and force application of traditional knives or pruning shears do not conform to ergonomic principles. During operation, the hand is often in an unnatural twisted or excessively forceful state, especially the thumb and forefinger need to continuously provide a large grip force to achieve cutting. Prolonged work can easily lead to muscle fatigue and even strain in the hands and wrists, which not only reduces the comfort of the worker, but also limits the duration and efficiency of continuous work.

[0005] The operation is cumbersome and the harvesting efficiency is low: the existing tools have limited functions, and actions such as clamping fruits and vegetables, cutting stems, and releasing fruits require multiple hand movements or the coordination of both hands to complete. This discontinuous operation process disrupts the continuity of harvesting, making it difficult to effectively increase the harvesting quantity per unit time and failing to meet the efficiency requirements of large-scale harvesting operations.

[0006] Insufficient safety and risk of accidental injury: The blades of most harvesting tools are directly exposed, making it easy to cut the operator or puncture the fruit when moving through dense foliage or when stored in a pocket. In addition, the lack of an effective safety locking mechanism means that if the tools are accidentally activated when not in use (such as when being carried), they may cause serious personal injury to the user.

[0007] Inconvenient maintenance, high operating costs, and negative impacts on plant health: Traditional cutting tools often have fixed blades, which, once worn or chipped, result in rough, uneven cuts. These uneven cuts not only increase the risk of plant infections, affecting subsequent growth, but may also render the entire tool unusable, increasing long-term operating costs for users. The non-replaceable blade design also hinders the tool from maintaining optimal working condition, impeding the widespread adoption of the technology.

[0008] Therefore, there is an urgent need in this field for a new type of fruit and vegetable harvesting tool that can comprehensively solve the above problems. Utility Model Content

[0009] The purpose of this utility model is to provide a fruit and vegetable harvesting knife that solves the problems of hand fatigue, inconsistent operation, poor safety, and difficult blade maintenance of traditional tools.

[0010] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] This utility model discloses a fruit and vegetable harvesting knife, including a support plate, a connecting plate on the top surface of the support plate, an upper blade holder rotatably mounted on the connecting plate, a torsion spring on the outer side of the connecting plate, with both ends of the torsion spring respectively mounted on the support plate and the upper blade holder, the upper blade holder being equipped with a detachable and replaceable blade, a self-locking structure on the connecting plate, which locks the position of the upper blade holder after the upper blade holder and the support plate are closed to prevent accidental opening; a finger ring is provided on the top surface of the support plate.

[0012] Furthermore, the number of connecting plates is set to two, and the upper tool holder is disposed between the two connecting plates.

[0013] Furthermore, the upper tool holder is connected to the connecting plate via a rotating shaft.

[0014] Furthermore, the upper blade holder is provided with a mounting groove, and the blade is disposed in the mounting groove and locked in place by screws.

[0015] Furthermore, the self-locking structure includes a sliding groove on the connecting plate, a limiting pin that can slide back and forth in the sliding groove, and a locking slot on the upper tool holder; when the limiting pin is pushed forward, the upper tool holder can open and close freely; when the limiting pin is pushed backward, it can lock the locking slot at the base of the upper tool holder, forming a self-locking structure, and the upper tool holder is closed with the support plate.

[0016] Furthermore, the top surface of the upper tool holder is provided with anti-slip patterns.

[0017] Furthermore, the anti-slip pattern is made of soft rubber material.

[0018] Furthermore, the front end of the upper tool holder is set to be arc-shaped.

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

[0020] This utility model features a compact structure, simple operation, and high harvesting efficiency. Its design fully considers ergonomic principles, allowing the hand to be in a semi-fist position during operation, with the thumb and index finger at nearly 90°. When the thumb presses down, the index finger provides support, while the other three fingers also provide auxiliary support, achieving effortless operation and effectively alleviating fatigue from prolonged work. The operator can complete the clamping, cutting, and releasing actions with just one hand, greatly improving continuous harvesting efficiency.

[0021] This utility model has good safety: it adopts a protective design with the blade placed inside the upper blade holder, which can avoid punctures and wear; it has a self-locking structure design, which can lock the blade edge when the knife is not in use, preventing accidental contact and injury.

[0022] This invention is easy to maintain: the blade is replaceable, which helps to keep the cut smooth, reduces the risk of plant infection, lowers the cost of use, and makes it easier to promote. Attached Figure Description

[0029] like Figure 1-4 As shown, a fruit and vegetable harvesting knife includes a support plate 1. Two connecting plates 2 are connected to the top surface of the support plate 1. An upper blade holder 3 is rotatably connected to the connecting plates 2 via a rotating shaft 4. A torsion spring 6 is provided on the outer side of the connecting plates 2, with its two ends connected to the support plate 1 and the upper blade holder 3 respectively. The torsion spring 6 provides a restoring force and limits the maximum opening angle of the upper blade holder 3 to prevent excessive opening and loss of control. A detachable and replaceable blade 5 is provided on the upper blade holder 3. An installation groove is provided on the upper blade holder 3, and the blade 5 is installed in the installation groove and locked in place by screws 9. The blade 5 is fixed in the upper blade holder 3 by two screws and is replaceable. A self-locking structure is provided on the connecting plates 2. After the upper blade holder 3 and the support plate 1 are closed, the self-locking structure locks the position of the upper blade holder 3 to prevent accidental opening. A horizontal finger ring 7 is provided on the top surface of the support plate 1 for easy insertion of the index finger to provide support.

[0030] The self-locking structure includes a sliding groove 201 formed on the connecting plate 2, a limiting pin 8 that can slide back and forth is provided in the sliding groove 201, and a bayonet 301 is provided on the upper knife holder 3; when the limiting pin 8 is pushed forward, the upper knife holder 3 can open and close freely, which is convenient for picking operations; when the upper knife holder 3 is closed with the support plate 1, the limiting pin 8 is pushed backward, which can lock the bayonet 301 at the base of the upper knife holder 3, forming a self-locking structure to prevent accidental opening.

[0031] The top surface of the upper knife holder 3 is connected with a soft rubber anti-slip pattern 302, which facilitates thumb pressing operation.

[0032] The front end of the upper blade holder 3 is set in an arc shape, which facilitates the fruit stem entering the blade position.

[0033] Specifically, in actual production, the support plate 1, connecting plate 2, and finger ring 7 can be integrally molded. The support plate 1, connecting plate 2, finger ring 7, and upper tool holder 3 can be made of plastic.

[0034] The working process of this utility model is as follows:

[0035] During harvesting, the stem or branch of the fruit or vegetable to be harvested is placed between the blade 5 and the support plate 1. The index finger is inserted into the ring 7 below the support plate 1 to provide support, while the thumb applies pressure to the upper blade holder 3, causing it to rotate around the rotation axis 4, thus driving the blade 5 to complete the cut. After releasing, the upper blade holder 3 automatically returns to its original position under the action of the torsion spring 6. In practical applications, the operator can complete the clamping, cutting, and releasing actions with one hand, greatly improving continuous harvesting efficiency. This knife has a compact structure, is easy to operate, and can effectively avoid squeezing and accidentally damaging the fruit.

[0036] This embodiment proposes a fruit and vegetable harvesting knife. Through its ingenious structural design, it improves harvesting efficiency and yield. It is suitable for non-destructive harvesting of solanaceous or berry fruits and vegetables such as peppers, tomatoes, and grapes. It solves the problems of existing harvesting tools that easily damage fruits, are inconvenient to operate, and are inefficient during use. It has good practicality and promotional value.

[0037] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
