Description

Technical Field

[0001] This utility model relates to a shearing device, specifically a portable fruit and vegetable stem shearing device. Background Technology

[0002] In the fruit and vegetable harvesting process, many varieties (such as tomatoes, green peppers, apples, and oranges) require short stems or the removal of excessively long stalks to avoid damaging the fruit or affecting subsequent storage. Manual cutting relies on tools such as scissors and blades, which is not only inefficient (each person can only process a few thousand fruits and vegetables per day), but also prone to inconsistent cutting positions due to hand fatigue, affecting the appearance and even scratching the fruit.

[0003] At the same time, when pruning, one hand needs to hold the pruning tool and the other hand to support the fruit and vegetables to prevent them from falling after pruning, which greatly affects the pruning efficiency. Moreover, when the fruit trees are tall, it is more strenuous to lift them with both hands, which increases the fatigue of workers and reduces pruning efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a portable fruit and vegetable stem cutting device that solves the problems of existing technology and reduced fruit and vegetable cutting efficiency.

[0005] The above-mentioned technical objective of this utility model is mainly achieved through the following technical solution: a portable fruit and vegetable stem cutting device, including a fixed block, a grip handle at the front end of the fixed block, and a first movable seat and a second movable seat that can automatically move closer to or further away from each other at the rear end of the fixed block.

Detailed Implementation

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0015] like Figure 1 As shown, a portable fruit and vegetable stem cutting device includes a fixed block 1. The front end of the fixed block 1 has a handle 2 for the operator to grip. The handle 2 is small and portable. The rear end of the fixed block 1 has a first movable seat 31 and a second movable seat 32 that can automatically move closer or further apart. On opposite sides of the first movable seat 31 and the second movable seat 32 are a first cutting blade 33 and a second cutting blade 34 for cutting stems, which can move closer or further apart. The first movable seat 31 and the second movable seat 32 can automatically move relative to each other on the side wall of the fixed block 1, thereby driving the first cutting blade 33 and the second cutting blade 34 to move relative to each other. When the first shearing blade 33 and the second shearing blade 34 move close to each other, they can automatically cut the fruit and vegetable stems. When the first shearing blade 33 and the second shearing blade 34 move away from each other, the cutting of the fruit and vegetable stems is completed, making the cutting of fruit and vegetable stems more labor-saving. The top of the first moving base 31 and the second moving base 32 are respectively provided with a first arc-shaped cover 35 and a second arc-shaped cover 36 symmetrically arranged above the first shearing blade 33 and the second shearing blade 34. The bottom of the first arc-shaped cover 35 and the second arc-shaped cover 36 are respectively rotatably connected to the first moving base 31 and the second moving base 32. A torsion spring 37 is provided at the rotation center of the bottom of the first arc-shaped cover 35 and the second arc-shaped cover 36. The first shearing blade 33 and the second shearing blade 34 are respectively located at the top of the first movable seat 31 and the second movable seat 32. Both can be rotated towards the middle of the first movable seat 31 and the second movable seat 32 under the action of the torsion spring 37. When the first movable seat 31 and the second movable seat 32 move away from each other, the first shearing blade 33 and the second shearing blade 34 also move away. Subsequently, the fruit and vegetable stems are located between the first shearing blade 33 and the second shearing blade 34, while the fruit and vegetables are located between the first arc-shaped cover 35 and the second arc-shaped cover 36. The first arc-shaped cover 35 and the second arc-shaped cover 36 are pressed against the sides of the fruit and vegetables by the action of the torsion spring 37. The inner walls of the first arc-shaped cover 35 and the second arc-shaped cover 36 can be lined with soft materials such as cloth or rubber pads to avoid damaging the fruit and vegetables and to maintain the restraint of the fruit and vegetables. Next, the first movable seat 31 and the second movable seat 32 move closer to each other, and the first shearing blade 33 and the second shearing blade 34 move closer to each other to cut the fruit and vegetable stems. After being cut, the vegetables are limited and pressed by the first arc-shaped cover 35 and the second arc-shaped cover 36, which can prevent the vegetables from falling and causing damage to the vegetables after the stems are cut. After the cutting is completed, the device can be moved into the fruit and vegetable collection frame, and the first movable seat 31 and the second movable seat 32 move away from each other, so that the first arc-shaped cover 35 and the second arc-shaped cover 36 automatically separate. Thus, the fruits and vegetables can be placed into the collection frame without touching them with both hands. This not only realizes the automatic cutting of fruit and vegetable stems, but also effectively ensures the integrity of the fruits and vegetables and improves the cutting efficiency of fruit and vegetable stems.

[0016] like Figure 1-3 As shown, both the first shearing blade 33 and the second shearing blade 34 have several vertically penetrating slots 331 at their cutting edges. The cutting edges of the first shearing blade 33 and the second shearing blade 34 can respectively enter the slots 331 of the second shearing blade 33 and the first shearing blade 33, forming a cross shape. Through the arrangement of the slots 331, the cutting edges of the first shearing blade 33 and the second shearing blade 34 can cross each other when they come close together, making the cutting of the first shearing blade 33 and the second shearing blade 34 more thorough and reliable, improving the cutting quality of fruit and vegetable stems, ensuring that the fruit and vegetable stems are cut in place, and avoiding the fruit and vegetables from falling off due to incomplete cutting. The bottom of the first shearing blade 33 and the second shearing blade 34 are respectively provided with a first connecting block 332 and a second connecting block 341. The side wall of the first connecting block 332 is provided with a first bristle 33 that is obliquely upward towards the second shearing blade 34. 3. The side wall of the second connecting block 341 is provided with a second bristle 342 that is obliquely upward toward the first shearing blade 33. The first bristle 333 and the second bristle 342 are fixed to the bottom of the first shearing blade 33 and the second shearing blade 34 respectively through the first connecting block 332 and the second connecting block 341. The oblique upward arrangement of the first bristle 333 and the second bristle 342 allows the first bristle 333 and the second bristle 342 to brush the second shearing blade 34 and the first shearing blade 33 simultaneously when the first shearing blade 33 and the second shearing blade 34 are close to each other, thus cleaning the blades of the second shearing blade 34 and the first shearing blade 33 at the same time, reducing the residue of stems on the blades, avoiding long-term adhesion of stems that could damage the blades and affect the shearing quality. The first bristle 333 and the second bristle 342 are both curved and sparsely distributed, which can avoid interfering with the shearing of fruit and vegetable stems.

[0017] like Figure 3As shown, a fixing groove 11 is provided on the side wall of the fixing block 1. A first connecting part 311 and a second connecting part 321, respectively, are provided on the side walls of the first movable seat 31 and the second movable seat 32, respectively, to cooperate within the fixing groove 11. The first connecting part 311 and the second connecting part 321 support the first movable seat 31 and the second movable seat 32 to move stably within the fixing groove 11. A first limiting slider 312 and a second limiting slider 322 are respectively provided on the side walls of the first connecting part 311 and the second connecting part 321. A first limiting groove 111 and a second limiting groove 112, respectively, are provided on the inner wall of the fixing groove 11 to cooperate with the first limiting slider 312 and the second limiting slider 322. The first limiting slider 312 and the first limiting groove 111 affect the movement of the first connecting part 311. The first connecting part 311 moves smoothly and steadily, while the second limiting slider 322 and the second limiting groove 112 limit the movement of the second connecting part 321, ensuring smooth and steady movement. A positioning block 12 is provided between the first connecting part 311 and the second connecting part 321, corresponding to the middle of the fixed groove 11. The positioning block 12 is provided to limit the movement of the first connecting part 311 and the second connecting part 321 when they move closer to each other, so as to avoid excessive movement and collision damage to the first shearing blade 33 and the second shearing blade 34. The range of movement of the first connecting part 311 and the second connecting part 321 away from each other is limited and positioned by the first limiting groove 111 and the second limiting groove 112.

[0018] like Figure 4As shown, a chamber 13 is provided below the fixing groove 11. On one side of the inner wall of the chamber 13, corresponding to the lower part of the first connecting portion 311, a first transmission bar 41 is provided, connected to the bottom of the first connecting portion 311 and arranged along the moving direction of the first connecting portion 311. On the other side of the inner wall of the chamber 13, corresponding to the lower part of the second connecting portion 321, a second transmission bar 42 is provided, connected to the bottom of the second connecting portion 321 and arranged along the moving direction of the second connecting portion 321. The top of the first transmission bar 41 is connected to the bottom of the first connecting portion 311, and the top of the second transmission bar 42 is connected to the bottom of the second connecting portion 321. When the first connecting portion 311 and the second connecting portion 321 move, they can respectively drive the first transmission bar 41 and the second transmission bar 42 to move synchronously. The transmission bar 42 has a first strip-shaped slider 411 and a second strip-shaped slider 421 respectively on the side that abuts against the chamber 13. The inner wall of the chamber 13 has a first strip-shaped groove 131 and a second strip-shaped groove 132 that slide with the first strip-shaped slider 411 and the second strip-shaped slider 421 respectively. The first transmission bar 41 is connected to the inner wall of one side of the chamber 13 through the connection of the first strip-shaped slider 411 and the first strip-shaped groove 131, and moves stably and smoothly with the first connecting part 311. The second transmission bar 42 is connected to the inner wall of the opposite side of the chamber 13 through the connection of the second strip-shaped slider 411 and the second strip-shaped groove 132, and moves stably and smoothly with the second connecting part 321. A transmission bar is provided in the middle between the first transmission bar 41 and the second transmission bar 42. The gear 43 has a first gear set 412 on the first transmission bar 41 corresponding to the lower part of the second connecting portion 321, which meshes with one side of the transmission gear 43. The second transmission bar 42 has a second gear set 422 corresponding to the lower part of the first connecting portion 311, which meshes with the other side of the transmission gear 43. The first gear set 412 is distributed in a strip shape on a partial side wall of the first transmission bar 41 below the second connecting portion 321, and the second gear set 422 is distributed in a strip shape on a partial side wall of the second transmission bar 42 below the first connecting portion 311. The first transmission bar 41 is driven by the first gear set 412 meshing with the transmission gear 43, and the second transmission bar 42 is driven by the second gear set 422 meshing with the transmission gear 43. A drive motor 44 is located below the transmission gear 43. The output shaft faces upward and is coaxially connected to the transmission gear 43. When the drive motor 44 starts, the transmission gear 43 is driven to rotate. The transmission gear 43 drives the first transmission bar 41 and the second transmission bar 42 to move synchronously in opposite directions by meshing with the first gear set 412 and the second gear set 422 respectively. The first transmission bar 41 and the second transmission bar 42 can then drive the first connecting part 311 and the second connecting part 321 to move synchronously in opposite directions respectively. The first connecting part 311 and the second connecting part 321 drive the first shearing blade 33 and the second shearing blade 34 to move closer or further apart through the first moving seat 31 and the second moving seat 32 respectively, thereby realizing automatic shearing of fruit and vegetable stems, making the shearing of fruit and vegetable stems more labor-saving and effectively improving the shearing efficiency of fruit and vegetable stems.The handle 2 is equipped with a button that is connected to the drive motor 44 via signal or circuit. When the operator presses the button, the first shearing blade 33 and the second shearing blade 34 move closer together to perform a shearing action. When the button is pressed again, the first shearing blade 33 and the second shearing blade 34 move away from each other, thus realizing the automatic shearing of this device.
