Description

Technical Field

[0001] This utility model relates to the technical field of fruit picking equipment, and in particular to a passion fruit stem cutter. Background Technology

[0002] In the development of the passion fruit industry, the fruit harvesting stage is a crucial factor restricting its large-scale and industrialized development. Currently, the main method of passion fruit harvesting in the market is manual picking, where harvesters typically use ordinary scissors or similar tools to cut the fruit stems. This traditional method has many drawbacks, such as low harvesting efficiency, making it difficult to meet the harvesting needs of large-scale orchards.

[0003] When existing technical solutions are used,

[0004] (1) Its cutting structure design is unreasonable, mostly fixed, and the cutting blade and the cutter body are integrated, making it difficult to replace parts. When the cutting blade is damaged, it cannot be replaced individually, and the entire cutter needs to be discarded, which not only wastes resources but also significantly increases the cost of use;

[0005] (2) The fruit-picking shears have a straight head structure and a pointed structure, making it difficult to fold the whole device. They are large in size and difficult to carry. The pointed tip can easily cause scratches to the person carrying the fruit. The handle lacks anti-slip design, which can easily cause hand abrasions when workers use it for a long time. In addition, the tool can easily slip when hands are sweaty during the picking process, posing a safety hazard.

[0006] To address the above problems, this utility model provides a passion fruit stem cutter. Utility Model Content

[0007] The purpose of this utility model is to solve the problems of difficulty in replacing the cutting structure of the equipment, difficulty in carrying the tool and unsafe use in the existing technology, and to propose a passion fruit stem cutter.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a passion fruit stem cutter, comprising a first lever arm, an adjusting cutter mechanism, a rotating mechanism, and a second lever arm. The adjusting cutter mechanism is threadedly connected to one end of the first lever arm, and the rotating mechanism is rotatably connected to the other end of the first lever arm. The first lever arm and the second lever arm are rotatably connected through the rotating mechanism. The adjusting cutter mechanism includes threaded holes on both sides of the first lever arm. A connecting component is rotatably connected inside the threaded holes. A fixing plate is rotatably connected to the outer surface of the connecting component. The fixing plate is rotatably connected to one end of the first lever arm through the connecting component. A cutting blade is threadedly connected to the top of the fixing plate.

[0009] Furthermore, the cutting blade is threaded to both sides with connectors, and the cutting blade is threaded to the top of the fixing plate through the connectors.

[0010] Furthermore, the connecting assembly includes a rotating bolt threaded into the threaded hole, and a limiting nut is threaded onto the outer surface of the rotating bolt. The rotating bolt is threaded into the threaded hole via the limiting nut.

[0011] Furthermore, the rotating mechanism includes a fixed circular plate fixedly connected to the other end of the first lever arm, and the fixed circular plate is symmetrically arranged on both sides of the first lever arm.

[0012] Furthermore, a rotating shaft is rotatably connected inside the fixed circular plate, and limit plates are fixedly connected to both ends of the rotating shaft. A return spring is sleeved on the outer surface of the rotating shaft.

[0013] Furthermore, the rotating mechanism includes a rotating ring fixedly connected to one end of the second lever arm, the inside of the rotating ring being rotatably connected to the outer surface of the rotating shaft, and the return spring being snapped between the first lever arm and the second lever arm, the first lever arm and the second lever arm being rotatably connected through the rotating shaft.

[0014] Furthermore, the outer surfaces of the first lever arm and the second lever arm are fixedly connected with anti-slip sleeves for handles, and the other end of the second lever arm is threadedly connected with an adjusting cutter mechanism.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the cutting blade, connector, and return spring are designed to enable quick blade replacement through the threaded connection between the cutting blade and the connector. When the cutting blade is worn or damaged, the connector can be unscrewed to quickly replace the new cutting blade without replacing the entire cutter, effectively reducing operating costs and extending the service life of the cutter. The return spring automatically resets the first and second lever arms after each fruit stem is cut, eliminating the need for manual operation, greatly improving harvesting efficiency and convenience, while also reducing labor intensity.

[0017] 2. In this utility model, by setting the rotating bolt, the limiting nut and the anti-slip sleeve of the handle, the angle of the cutting blade can be flexibly adjusted by the rotating bolt and the limiting nut, and the cutting blade can be folded into the inside of the first force arm and the second force arm, reducing the overall volume of the device, making it convenient for workers to carry and store, and preventing the cutting blade from causing scratches to workers during carrying. The anti-slip sleeve of the handle effectively increases the grip friction, prevents the tool from slipping and the hands from being abraded, and improves the safety of operation.

Detailed Implementation

[0026] Please see Figure 1-6 This utility model provides a technical solution: a passion fruit stem cutter, including a first lever arm 1, an adjusting cutter mechanism 2, a rotating mechanism 3, and a second lever arm 4. The adjusting cutter mechanism 2 is threadedly connected to one end of the first lever arm 1, and the rotating mechanism 3 is rotatably connected to the other end of the first lever arm 1. The first lever arm 1 and the second lever arm 4 are rotatably connected through the rotating mechanism 3.

[0027] The following is a detailed explanation of the specific configuration and function of the adjusting cutter mechanism 2, the rotating mechanism 3, and the second lever arm 4.

[0028] In this embodiment: the adjusting cutter mechanism 2 includes threaded holes 21 on both sides of the first lever arm 1. A connecting component 22 is rotatably connected inside the threaded holes 21. A fixing plate 23 is rotatably connected to the outer surface of the connecting component 22. The fixing plate 23 is rotatably connected to one end of the first lever arm 1 through the connecting component 22. A cutting blade 24 is threadedly connected to the top of the fixing plate 23.

[0029] The aforementioned components achieve the following effects: the threaded hole 21 provides a mounting base for the connecting assembly 22, enabling the connecting assembly 22 to be securely connected to the first lever arm 1. The connecting assembly 22 is rotatably connected to the fixing plate 23. In conjunction with the rotatable connection between the fixing plate 23 and the first lever arm 1, the fixing plate 23 can rotate within a certain range, thereby driving the cutting blade 24 to adjust its angle.

[0030] Specifically, the cutting blade 24 has connecting pieces 25 threaded on both sides, and the cutting blade 24 is threaded to the top of the fixing plate 23 through the connecting pieces 25.

[0031] The effect achieved by the above components is that the threaded connection makes the connection between the cutting blade 24 and the fixing plate 23 tight and stable, ensuring that the cutting blade 24 will not loosen or fall off when cutting the fruit stem. When the cutting blade 24 is worn or damaged, the operator only needs to use a tool to unscrew the connector 25 to quickly and easily disassemble the old blade and replace it with a new blade, which reduces maintenance costs and extends the service life of the cutter.

[0032] Specifically, the connecting component 22 includes a rotating bolt 221 that is threaded into the threaded hole 21. A limit nut 222 is threaded onto the outer surface of the rotating bolt 221, and the rotating bolt 221 is threaded into the threaded hole 21 through the limit nut 222.

[0033] The effects achieved by the above components are as follows: the rotating bolt 221 cooperates with the threaded hole 21 to connect the connecting component 22 with the first lever arm 1, and the fixed plate 23 can be rotated by rotating the rotating bolt 221 to achieve fine adjustment of the angle of the cutting blade 24. The limiting nut 222 plays the role of fixing and limiting. After the angle of the cutting blade 24 is adjusted, tightening the limiting nut 222 can prevent the rotating bolt 221 from loosening during use.

[0034] Specifically, the rotating mechanism 3 includes a fixed circular plate 31 fixedly connected to the other end of the first lever arm 1, and the fixed circular plate 31 is symmetrically arranged on both sides of the first lever arm 1.

[0035] The effect achieved by the above components is that the symmetrically arranged fixed circular plates 31 provide a stable and symmetrical support structure for the rotating shaft 32, ensuring that the rotating shaft 32 is subjected to uniform force during rotation and is not prone to deviation or shaking.

[0036] Specifically, a rotating shaft 32 is rotatably connected inside the fixed circular plate 31, and limit plates 33 are fixedly connected to both ends of the rotating shaft 32. A return spring 34 is sleeved on the outer surface of the rotating shaft 32.

[0037] The effect achieved by the above components is that the return spring 34 can store and release elastic potential energy after the first lever arm 1 and the second lever arm 4 are opened and closed by force, providing reset power for the two lever arms, so that the cutter can automatically return to the initial state after completing a cutting operation without manual reset, thereby improving harvesting efficiency and reducing the labor intensity of operators.

[0038] Specifically, the rotating mechanism 3 includes a rotating ring 35 fixedly connected to one end of the second lever arm 4. The inside of the rotating ring 35 is rotatably connected to the outer surface of the rotating shaft 32. The return spring 34 is engaged between the first lever arm 1 and the second lever arm 4. The first lever arm 1 and the second lever arm 4 are rotatably connected through the rotating shaft 32.

[0039] The effect achieved by the above components is that the rotating ring 35 is rotatably connected to the rotating shaft 32, so that the second lever arm 4 can rotate flexibly around the rotating shaft 32, and cooperate with the first lever arm 1 to achieve the clamping and cutting action of the passion fruit stem.

[0040] Specifically, the outer surfaces of the first lever arm 1 and the second lever arm 4 are fixedly connected with a handle anti-slip sleeve 5, and the other end of the second lever arm 4 is threadedly connected with an adjusting cutter mechanism 2.

[0041] The effects achieved by the above components are as follows: the handle anti-slip sleeve 5 is made of a material with good anti-slip properties. The textured surface increases the friction between the operator's hand and the handle. Even in environments with sweaty hands or a damp orchard, it can effectively prevent the cutter from slipping out of the hand. At the same time, it reduces friction between the hand and the handle, avoids hand abrasions caused by prolonged use, and improves the safety and comfort of operation.

[0042] Working principle: When in use, the operator holds the anti-slip sleeve 5 on the handle of the first lever arm 1 and the second lever arm 4, adjusts the angle of the fixed plate 23 in the cutting mechanism 2 by rotating the rotating bolt 221, and then adjusts the cutting blade 24 to the appropriate position, and tightens the limit nut 222 to fix it.

[0043] Then, bring the cutter close to the passion fruit, so that the stem is in a suitable cutting position on the cutting blade 24. Grip the first lever arm 1 and the second lever arm 4 tightly. The two lever arms rotate relative to each other around the rotating shaft 32. The rotating ring 35 rotates on the rotating shaft 32, which drives the cutting blade 24 to clamp and cut the stem. During the cutting process, the return spring 34 is compressed and stores elastic potential energy. When the stem is cut off, the return spring 34 releases the elastic potential energy and pushes the first lever arm 1 and the second lever arm 4 back to the initial open state, completing one cutting operation.

[0044] If the cutting blade 24 is worn, it can be quickly replaced by unscrewing the connector 25. When not in use, the adjusting cutter mechanism 2 at the other end of the second lever arm 4 can be folded close together to reduce the size of the cutter for easy carrying.
