Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural tool technology, concretely relates to a handheld asparagus lettuce leaf removing device. BACKGROUND

[0002] Asparagus lettuce, also known as lettuce, green asparagus or stem lettuce, is a widely planted vegetable belonging to the Lactuca genus of the Asteraceae family. Its stem is thick and crisp, with a light green or emerald green color, a fresh and crisp taste, and rich nutrition, making it one of the most common food materials on people's tables.

[0003] Both the stem and leaves of asparagus lettuce are edible. When asparagus lettuce grows to a certain maturity, its stem becomes plump and crisp, making it the best time to eat the stem. The leaves can be picked and eaten at any time during the growth process, especially during the tender leaf stage, as the taste is better. The leaves at the top of the asparagus lettuce are relatively more tender.

[0004] When picking asparagus lettuce, most of the leaves need to be removed before harvesting. Traditional leaf removal methods mainly use manual leaf breaking or machine picking. Manual leaf breaking can preserve tender leaves, but it is difficult to quickly remove dense leaves, especially for mature asparagus lettuce with thick stems. Machine picking is efficient, but it cannot specifically protect tender leaves.

[0005] The manual asparagus lettuce leaf removal tool uses a fixed-size leaf removal ring, so it can only remove leaves from asparagus lettuce at a specific stage and cannot remove leaves from asparagus lettuce at all growth stages. SUMMARY

[0006] The utility model aims to provide a handheld asparagus lettuce leaf removing device to solve the problem of the diameter of the leaf removal ring in the prior art being unable to be adjusted.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a handheld asparagus lettuce leaf removing device, comprising a longitudinal rod body and a handle arranged at the top end of the longitudinal rod body, the bottom end of the longitudinal rod body is symmetrically provided with a first outer ring and a second outer ring, the first outer ring and the second outer ring are coaxially fixedly installed with a first connecting sleeve and a second connecting sleeve at one end close to each other, the first connecting sleeve and the second connecting sleeve are rotationally connected with the outer side of the longitudinal rod body, an adjusting unit is arranged on the outer side of the bottom end of the longitudinal rod body, the adjusting unit comprises a partition ring fixedly installed on the outer side of the bottom end of the longitudinal rod body, the partition ring is located at the bottom of the second connecting sleeve, a plurality of through holes are arranged in the top of the first connecting sleeve and the second connecting sleeve in a circular array, a locking unit is arranged on the top of the first connecting sleeve, the locking unit comprises a locking ring sleeved on the outer side of the longitudinal rod body and a locking pin fixedly installed at the bottom end of the locking ring, the locking pin is inserted into the through hole by pressing the locking ring to fix the opening angle of the first outer ring and the second outer ring.

[0008] Further, the through hole of the first connecting sleeve is a first locking hole, and the through hole of the second connecting sleeve is a second locking hole.

[0009] Further, the adjusting unit further comprises:

[0010] A fixed ring is fixedly installed outside the longitudinal rod body, and the fixed ring is located above the first connecting sleeve.

[0011] A spring is sleeved outside the longitudinal rod body, and the spring is located below the fixed ring, one end of the spring abuts against the fixed ring, and the other end of the spring abuts against the locking ring.

[0012] Further, the locking unit further comprises:

[0013] An adjusting block is fixedly installed outside the locking ring in a circumferential direction.

[0014] Further, the top of the separation ring is provided with a plurality of through holes in a circumferential array, and the locking pin sequentially passes through the first locking hole of the first connecting sleeve, the second locking hole of the second connecting sleeve and the through hole of the separation ring, so as to lock the first outer ring and the second outer ring.

[0015] Further, the outer diameter of the separation ring is greater than the inner diameter of the second connecting sleeve.

[0016] Compared with the prior art, the handheld lettuce leaf removing device provided by the utility model can adjust the opening angle of the outer ring through multiple gears, adapt to the size change of the stem of lettuce from the growth period to the mature period, and avoid the stem extrusion or leaf residue caused by the size fixation of the traditional tool.

[0017] The first outer ring and the second outer ring do not directly contact the neck of the lettuce, and the stem surface and the top tender leaf are protected while the leaves are removed from top to bottom, so that the qualified rate of picking is improved.

[0018] The spacing adjustment of the first outer ring and the second outer ring can be completed by adjusting the locking pin of the locking ring to be clamped into different first locking holes and second locking holes, and the spring is automatically locked, so that the device is suitable for continuous operation in the field.
