Description

Technical Field

[0001] This utility model relates to the field of vegetable harvester technology, specifically a vegetable harvester with a protective structure. Background Technology

[0002] Traditional manual vegetable picking can easily damage vegetables by pinching and tearing them, and it also causes hand fatigue. Therefore, electric handheld vegetable pickers have appeared on the market. They use rechargeable batteries and control the opening and closing of the blades via buttons, which can greatly reduce hand fatigue and are especially suitable for large-scale harvesting operations. However, the blades (scissor blades or rotating blades) of existing electric handheld harvesters are mostly exposed to the outside, posing certain safety hazards during operation. For example, if the harvester falls accidentally and hits the operator's feet, the exposed blades may cause injury. Therefore, in order to further improve the safety of using electric handheld harvesters, a vegetable harvester with a protective structure is provided. Utility Model Content

[0003] The purpose of this utility model is to provide a vegetable harvester with a protective structure in order to solve the problems mentioned above.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vegetable harvester with a protective structure, comprising an electric harvester consisting of a main shell, a V-shaped fixed blade holder, and scissor blades. The scissor blades are attached to the upper surface of the V-shaped fixed blade holder, and the V-shaped fixed blade holder and scissor blades extend from the front end of the main shell to the interior of the main shell. The V-shaped fixed blade holder is fixed relative to the main shell. The scissor blades are rotatably connected to the main shell via a pin. A connecting seat is symmetrically fixed at the bottom front end of the main shell. A protective component is installed on the main shell via the connecting seat. The protective component is used to shield the parts of the V-shaped fixed blade holder and scissor blades exposed outside the main shell. The protective components include an L-shaped protective cover and a torsion spring; The L-shaped protective cover is rotatably installed between two connecting seats via a rotating shaft, and the front vertical part of the L-shaped protective cover is located in front of the V-shaped fixed knife seat and the scissor blade, which is used to block the sharp front end of the V-shaped fixed knife seat and the scissor blade. The torsion spring is sleeved on the outside of the rotating shaft of the L-shaped protective cover, and the two ends of the torsion spring are respectively engaged with the L-shaped protective cover and the connecting seat, so as to provide the L-shaped protective cover with an upward rotation torque.

[0005] As a further improvement of this utility model, the protective component also includes a snap-fit ​​groove, an L-shaped locking block, a spring, and an electromagnetic block; The snap-fit ​​groove is located at the middle of one end of the bottom plate of the L-shaped protective cover near the main body of the outer shell. The L-shaped locking block extends from the inside of the main body of the outer shell to the outside of the front end of the main body of the outer shell and is distributed below the L-shaped protective cover. When the L-shaped protective cover is rotated to the vertical position, the L-shaped locking block is engaged in the snap-fit ​​groove to lock the L-shaped protective cover in the vertical position. The springs are distributed at the rear end of the vertical part of the L-shaped locking block and fit against the vertical fixing plate formed inside the outer shell body, and are used to provide the L-shaped locking block with a thrust toward the front end; The electromagnetic block is installed inside the outer shell and behind the vertical part of the L-shaped lock block. The electromagnetic block is connected to electricity to generate magnetic attraction force to attract and retract the L-shaped lock block, thereby unlocking the L-shaped protective cover.

[0006] As a further embodiment of this utility model: the rear end of the scissor blade extends into the interior of the outer shell body and has a straight groove. A drive motor is installed inside the outer shell body below the scissor blade. A turntable is fixed to the top of the output end of the drive motor. An eccentric column is eccentrically fixed to the top of the turntable. The eccentric column is slidably connected to the straight groove. The eccentric cylinder is driven by a drive motor to rotate in a circular motion to achieve the reciprocating swing operation of the scissor blades.

[0007] As a further improvement of this utility model: a button switch is installed at the front end of the handle part of the outer shell body, and an infrared sensor is installed at the rear end of the handle part of the outer shell body; The drive motor is electrically connected to the push-button switch, the controller inside the housing, and the power supply via wires.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-6In this embodiment of the utility model, a vegetable harvester with a protective structure includes an electric harvester 1 consisting of a main body 101, a V-shaped fixed blade seat 104, and a scissor blade 105. The scissor blade 105 is attached to the upper surface of the V-shaped fixed blade seat 104, and the V-shaped fixed blade seat 104 and the scissor blade 105 extend from the front end of the main body 101 into the interior of the main body 101. The V-shaped fixed blade seat 104 is fixed relative to the main body 101. The scissor blade 105 is rotatably connected to the main body 101 via a pin. A connecting seat 110 is symmetrically fixed at the bottom front end of the main body 101. A protective component 2 is installed on the main body 101 via the connecting seat 110. The protective component 2 is used to cover the parts of the V-shaped fixed blade seat 104 and the scissor blade 105 exposed outside the main body 101. Protective component 2 includes an L-shaped protective cover 201 and a torsion spring 202; The L-shaped protective cover 201 is rotatably mounted between two connecting seats 110 via a rotating shaft, and the vertical front end of the L-shaped protective cover 201 is located in front of the V-shaped fixed knife seat 104 and the scissor blade 105, which is used to block the sharp front ends of the V-shaped fixed knife seat 104 and the scissor blade 105. The torsion spring 202 is sleeved on the outside of the rotating shaft of the L-shaped protective cover 201, and the two ends of the torsion spring 202 are respectively engaged with the L-shaped protective cover 201 and the connecting seat 110, which is used to provide the L-shaped protective cover 201 with upward rotation torque; The protective component 2 also includes a snap-fit ​​groove 203, an L-shaped locking block 204, a spring 205, and an electromagnetic block 206; The snap-fit ​​groove 203 is located at the middle of one end of the bottom plate of the L-shaped protective cover 201 near the outer shell body 101. The L-shaped locking block 204 extends from the inside of the outer shell body 101 to the outside of the front end of the outer shell body 101 and is distributed below the L-shaped protective cover 201. When the L-shaped protective cover 201 is rotated to the vertical position, the L-shaped locking block 204 is snapped into the snap-fit ​​groove 203 to lock the L-shaped protective cover 201 in the vertical position. Springs 205 are distributed at the rear end of the vertical part of the L-shaped locking block 204 and are attached to the vertical fixing plate formed inside the housing body 101, and are used to provide the L-shaped locking block 204 with a thrust toward the front end; The electromagnetic block 206 is installed inside the outer shell body 101 and located behind the vertical part of the L-shaped locking block 204. The electromagnetic block 206 is connected to the power to generate magnetic attraction force to attract and retract the L-shaped locking block 204, thereby unlocking the L-shaped protective cover 201. A push-button switch 102 is installed at the front end of the handle of the main body 101, and an infrared sensor 103 is installed at the rear end of the handle of the main body 101.

[0014] In this embodiment, it should be noted that: protrusions are formed on the side of the two connecting seats 110 that are close to each other. When the L-shaped protective cover 201 is horizontal, the upper surface of the bottom plate of the L-shaped protective cover 201 is in contact with the lower surface of the protrusion, which is used to limit the horizontal position of the L-shaped protective cover 201. At the same time, the torsion spring 202 is always in a torsional state, that is, the torsion spring 202 always provides an upward flipping force for the L-shaped protective cover 201. When storing this electric harvester 1, the L-shaped protective cover 201 is in a horizontal position, which blocks the sharp ends of the V-shaped fixed blade holder 104 and the scissor blades 105. The operating method is as follows: First, manually flip the L-shaped protective cover 201 downwards. During this process, the torsion spring 202 is further twisted and deformed. At the same time, the L-shaped protective cover 201 compresses the L-shaped locking block 204, causing it to retract into the outer shell body 101 (it should be noted that the upper surface of the lateral part of the L-shaped locking block 204 near the end of the L-shaped protective cover 201 has an arc structure), and its spring 205 is further compressed under force. When the L-shaped protective cover 201 rotates to the vertical position, the snap-fit ​​groove 203 on the L-shaped protective cover 201 is aligned with the horizontal part of the L-shaped locking block 204. At this time, the L-shaped locking block 204 is reset under the elastic force of the spring 205, and its horizontal part is engaged in the inner side of the snap-fit ​​groove 203, thereby achieving the locking of the L-shaped protective cover 201 in the vertical position. Then the vegetable harvesting operation can be carried out. During this process, the vertical L-shaped protective cover 201 is distributed in front of the button switch 102, which can block the space in front of the button switch 102. This can prevent the branches and leaves of the vegetables from contacting the hand pressing the button switch 102, thus protecting the hand. Meanwhile, when the operator grips the outside of the handle of the outer shell 101, the infrared sensor 103 detects and sends a signal to the controller. When the electric harvester 1 falls accidentally, the signal of the infrared sensor 103 changes. At this time, the controller controls the electromagnetic block 206 to turn on the power. The electromagnetic block 206 generates a magnetic attraction force and attracts the L-shaped locking block 204, causing the L-shaped locking block 204 to retract into the outer shell 101. At this time, the L-shaped locking block 204 separates from the locking groove 203, that is, the locking of the L-shaped protective cover 201 is released. The L-shaped protective cover 201 will quickly return to the horizontal state under the force of the torsion spring 202, and once again achieve the shielding and protection of the V-shaped fixed blade holder 104 and the scissor blade 105. In this way, not only can the V-shaped fixed blade holder 104 and the scissor blade 105 be prevented from falling to the ground and being damaged by collision, but also the V-shaped fixed blade holder 104 and the scissor blade 105 can be prevented from contacting the operator's feet and causing injury to the operator's feet, thus effectively improving the safety of using the electric harvester 1.

[0015] Please refer to this carefully. Figures 1-3 The rear end of the scissor blade 105 extends into the interior of the outer shell 101 and has a straight slot 106. Inside the outer shell 101, below the scissor blade 105, a drive motor 107 is installed. A turntable 108 is fixed to the top of the output end of the drive motor 107. An eccentric column 109 is eccentrically fixed to the top of the turntable 108. The eccentric column 109 is slidably connected to the straight slot 106. The eccentric column 109 is driven to rotate in a circular motion by the drive motor 107 to realize the reciprocating swing operation of the shear blade 105. The drive motor 107 is electrically connected to the push button switch 102, the controller inside the housing 101, and the power supply via wires. Electromagnetic block 206 and infrared sensor 103 are electrically connected to the controller and power supply inside the outer casing 101 via wires. The outer shell 101 has a groove for the L-shaped locking block 204 to slide within it, an mounting slot for the drive motor 107 and the electromagnetic block 206 to be fixed within it, and a cavity structure for the scissor blade 105 and the turntable 108 to run within it.

[0016] In this embodiment: the start and stop of the drive motor 107 can be controlled by the button switch 102. When the drive motor 107 is running, it drives the turntable 108 to rotate. The turntable 108 drives the eccentric column 109 to run in a circle. During this process, with the structural cooperation of the straight groove 106, the scissor blade 105 can swing back and forth around the pin shaft. The swinging scissor blade 105 cooperates with the V-shaped fixed blade seat 104 to form a "scissor" structure, thereby realizing the cutting and picking operation of vegetables. Infrared sensor 103 is used to detect the operator's gripping state. When the operator is normally gripping the handle of the outer shell 101, electromagnet 206 is de-energized. When the operator releases the grip on the handle, the signal of infrared sensor 103 changes. At this time, the controller controls electromagnet 206 to be energized to generate magnetic attraction, causing L-shaped locking block 204 to reset and release the locking of L-shaped protective cover 201. L-shaped protective cover 201 quickly resets under the action of torsion spring 202 to achieve shielding and protection of V-shaped fixed blade holder 104 and scissor blade 105.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
