[0021] This utility model proposes a leek harvesting device 100.

[0022] Please see Figures 1-6In one embodiment of this utility model, the leek harvesting device 100 includes a vehicle body 10 and a cutting structure 20. The cutting structure 20 includes a blade holder 21 and a cutting blade 22. The blade holder 21 is mounted on the front end of the vehicle body 10, and the cutting blade 22 is mounted on the bottom of the blade holder 21. A power source 23 is provided on the blade holder 21, and the output end of the power source 23 is connected to the cutting blade 22. A support frame 30 is provided on the blade holder 21, and a slider 31 is provided on the support frame 30. The slider 31 can move along the support frame 30. A rotating shaft 40 is provided on the slider 31, and a paddle 41 is provided on the rotating shaft 40. A conveyor belt 50 is provided inside the vehicle body 10. The rotating shaft 40 can drive the paddle 41 to push the cut leeks towards the conveyor belt 50. A storage box 11 is provided at the end of the conveyor belt 50, and the conveyor belt 50 transports the leeks into the storage box 11.

[0023] In this embodiment, the vehicle body 10 is integrally formed from high-strength alloy steel. The blade holder 21 is fixedly installed at the front end of the vehicle body 10 with precision bolts to ensure stability during operation in complex terrain and to facilitate disassembly. The power source 23 is a high-torque DC motor, and its output end is connected to the main shaft of the cutting blade 22 through a high-precision coupling to achieve efficient power transmission. The support frame 30 is fixedly connected to the blade holder 21 by welding. The conveyor belt 50 is a frequency-controlled conveyor belt made of food-grade rubber with raised bumps on its surface to ensure that the chives do not slip during transport.

[0024] In one embodiment of the present invention, the support frame 30 is provided with a sliding groove 33, the slider 31 is movably mounted in the sliding groove 33, and the top of the support frame 30 is provided with a rotating member 32, which passes through the sliding groove 33 and is connected to the slider 31.

[0025] The support frame 30 has a limiting groove 34 on one side wall, and a limiting platform 35 is provided at one end of the slider 31. The limiting platform 35 is locked in the limiting groove 34. The support frame 30 has a notch 36 on the other side wall. The notch 36 penetrates the side wall and communicates with the sliding groove 33. One end of the slider 31 is exposed outside the support frame 30 from the notch 36.

[0026] In this embodiment, the rotating component 32 can be a bolt, but is not limited to this. The rotating component 32 can rotate on the support frame 30 but will not detach from the support frame 30. It is understood that the rotating component 32 has external threads, and the hole connecting the slider 31 and the rotating component 32 has internal threads. The two are connected by threads. With the cooperation of the limiting groove 34 and the limiting platform 35, the movement of the slider 31 can be limited. When the rotating component 32 is rotated, the slider 31 will not rotate with the rotating component 32, but can only move along the sliding groove 33. By rotating the rotating component 32, the slider 31 can be moved within the sliding groove 33, thereby adjusting the position of the paddle 41 to adapt to chives with different growth densities and heights, ensuring that the cut chives can be accurately pushed onto the conveyor belt 50.

[0027] In one embodiment of the present invention, a drive member 52 is provided on the vehicle body 10, and the output end of the drive member 52 is connected to a first support column 51. The drive roller 53 on the conveyor belt 50 is connected to the first support column 51. A second support column 54 is provided inside the vehicle body 10. The second support column 54 is located below the first support column 51. The driven roller 55 on the conveyor belt 50 is connected to the second support column 54, so that the conveyor belt 50 is inclined from bottom to top.

[0028] In this embodiment, the driving component 52 may be a servo drive motor of model XJ-120, but is not limited to this. The active roller 53 on the conveyor belt 50 is fixedly assembled with the first support column 51 by a key connection. The two transmit torque through a flat key. When the driving component 52 is powered on, its output end generates a stable torque, which drives the first support column 51 to perform circumferential motion. Then, the power is transmitted to the active roller 53 through the key connection, so that the conveyor belt 50 can operate normally and realize the conveying of chives.

[0029] The second support column 54 is located below the first support column 51. It uses gravity to make the chives move more smoothly during the transport process, avoids the chives from piling up on the conveyor belt 50, and also makes it easier to transport the chives to the storage box 11 located at the end of the conveyor belt 50.

[0030] In one embodiment of the present invention, the vehicle body 10 is provided with a first pulley 42, and the slider 31 is provided with a second pulley 43. The first pulley 42 and the second pulley 43 are connected by a belt 44.

[0031] In this embodiment, the first pulley 42 is driven to rotate by a motor. The motor drives the first pulley 42 to rotate counterclockwise. Through the transmission cooperation of the first pulley 42, the second pulley 43 and the belt 44, the second pulley 43 is also driven to rotate counterclockwise. This causes the rotating shaft 40 to drive the paddle 41 to rotate counterclockwise, ensuring that the paddle 41 can push the cut chives towards the conveyor belt 50.

[0032] In one embodiment of the present invention, the tool holder 21 is provided with a mounting platform 24, and the power source 23 is installed in the mounting platform 24.

[0033] In this embodiment, the mounting platform 24 is located in the middle of the knife holder 21 and its area is smaller than the channel of the knife holder 21. It will not block the chives from entering the conveyor belt 50. At the same time, it can protect the power source 23, prevent the power source 23 from being damaged by external factors during the operation of the device, and extend the service life of the power source 23.

[0034] In one embodiment of this utility model, the vehicle body 10 is provided with an opening and closing door 12, which is used to take out the chives in the storage box 11.

[0035] The opening and closing door 12 is connected to the vehicle body 10 via a miniature hinge, allowing it to be opened and closed. This opens the storage box 11, facilitating the operator's retrieval of the harvested chives and improving the ease of use of the device. The bottom of the vehicle body 10 is equipped with casters 13 for easy movement and harvesting, and the rear end of the vehicle body 10 is equipped with a push rod 14 for easy pushing by the operator.

[0036] Working principle: First, the power source 23, the drive unit 52, and the motor connected to the first pulley are started. The power source 23 drives the cutting blade 22 to rotate at high speed. When pushing the vehicle body 10 forward, the cutting blade 22 cuts the chives in front of the vehicle body. While the cutting blade is cutting the chives, the drive unit 52 drives the first support column 51 to rotate, causing the conveyor belt 50 to start running. The motor drives the paddle 41 to rotate counterclockwise through belt transmission, pushing the cut chives onto the conveyor belt 50. After being pushed onto the conveyor belt 50, the chives are conveyed upwards under the drive of the conveyor belt 50 and finally conveyed to the storage box 11 located at the end of the conveyor belt 50 for collection. When a certain amount of chives has been collected in the storage box 11, the operator can open the opening door 12 on the vehicle body 10 to take out the chives from the storage box 11 for subsequent processing. The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
