Description

Technical Field

[0001] This invention relates to the field of leafy vegetable sowing technology, specifically to a device and method for removing the covering material after sowing leafy vegetables. Background Technology

[0002] Leafy vegetables refer to leafy greens with edible value, such as spinach, lettuce, and purple cabbage. These vegetables are an important part of a healthy diet, rich in vitamins, minerals, and dietary fiber, which help promote health and prevent disease. Leafy vegetables need to be watered during the sowing process. Watering with plenty of water helps the leaves grow. In the first few days after watering, it is necessary to prevent the liquid from running off. To prevent this, a covering is used. The covering is placed directly on the sowing site. The covering keeps the soil moist. When removing the covering, a covering removal device is needed to store and place the covering.

[0003] Chinese Patent Publication No. CN218088044U discloses a road moisture-retaining blanket storage device, including a handle, a support rod fixedly mounted at the end of the handle, the support rod being perpendicular to the handle; one end of the support rod is vertically bent and integrally extended with a connecting rod, the front end of the connecting rod being fixedly mounted with a rotating base, and a storage roller rotatably mounted on the rotating base; the storage roller is in the form of a circular roller, with barbs arrayed on its outer wall surface, the barbs being in the form of thin steel wire bent once, the arrayed barbs being bent in the same direction. This utility model has a simple structure, is easy to use, inexpensive, and easy to maintain. Through its simple structure, it solves the various inconveniences of moisture-retaining blanket storage in the prior art, realizing quick and convenient storage of moisture-retaining blankets, improving the recycling rate of moisture-retaining blankets, and has great promotional value.

[0004] In actual use, the storage device of the above-mentioned patent stores the cloth material by pressing and rotating. However, storing the covering material required for leafy vegetable sowing by pressing will damage the soil and the plants in the soil, affecting sowing. Therefore, it does not meet the existing needs. In response, we propose a covering removal device and method for leafy vegetable sowing. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for uncovering the covering after leafy vegetable sowing. Through transmission, a first transmission gear ring and a second transmission gear ring rotate. The rotation of the second transmission gear ring generates relative motion with the first transmission threaded rod, and vice versa. The simultaneous relative motion at both ends, mutually restricting each other, causes the device's storage bucket, first protective frame, second protective frame, and internal transmission structure to move longitudinally. When the covering is rotated for storage and then uncovered, the storage bucket, first protective frame, second protective frame, and internal transmission structure move from bottom to top. When the covering is placed to cover the sowing location, the storage bucket, first protective frame, second protective frame, and internal transmission structure move from top to bottom. This reduces friction between the covering and the soil surface, preventing damage to the sown vegetable leaves and avoiding soil adhesion to the covering surface, thus solving the problems mentioned in the background art.

A first upper sliding cavity is provided at the upper end inside the first protective frame, and a second upper sliding cavity is provided at the upper end outside the second protective frame.

[0016] The method for removing the covering device after leafy vegetable sowing includes the following steps:

[0017] Step 1: Start the output motor. The output shaft of the output motor drives the second column gear to rotate. The counterclockwise rotation of the second column gear can drive the first column gear to rotate clockwise. The first column gear can directly drive the upper second sector gear to rotate clockwise. The second sector gear can drive the first sector gear on the other side to rotate counterclockwise.

[0018] Step 2: The counterclockwise rotation of the first sector gear can drive the second transmission rod to rotate counterclockwise. The rotation of the second transmission rod drives the clamping protrusions on both sides of the upper outer end to rotate counterclockwise. The rotation of the clamping protrusions can drive the placement cavity to rotate counterclockwise. The placement cavity will drive one end of the inner covering to rotate counterclockwise. Continuous counterclockwise rotation can store the covering.

[0019] Step 3: The counterclockwise rotation of the second transmission rod will drive the third sector gear at one end to rotate counterclockwise. The third sector gear will drive the fourth sector gear at the lower end to rotate counterclockwise. The counterclockwise rotation of the fourth sector gear will drive the third column gear at the lower end to rotate counterclockwise. The third column gear will drive the second transmission gear ring on one side to rotate. The clockwise rotation of the first column gear will drive the first transmission gear ring on the other side to rotate. The interior of the first transmission gear ring and the exterior of the second transmission threaded rod will move relative to each other due to the rotation. After the first and second transmission threaded rods restrict each other, the second transmission gear ring and the first transmission gear ring will move longitudinally upward under the support of the second connecting plate and the first connecting plate, respectively. The longitudinal upward movement completes the unveiling of the cover.

[0020] Step 4: The third column gear drives the second transmission gear ring to rotate, which in turn drives the fourth column gear to rotate clockwise. The clockwise rotation of the fourth column gear drives the fifth sector gear at the top to rotate clockwise. The clockwise rotation of the fifth sector gear drives the sixth sector gear to rotate.

[0021] Step 5: The rotation of the sixth sector gear can drive the first transmission rod supported by the support frame to rotate. The rotating first transmission rod contacts the uncovered cover and cleans the soil from the lower end of the cover by rotating and rubbing.

[0022] Step Six: When the covering material is discharged and placed over the sowing position, the output motor starts and drives the second columnar gear to rotate clockwise. After the rotation of the second columnar gear is reversed through steps one to three, the device's collection bucket moves vertically downward while discharging the covering material, actively completing the covering of the sowing position.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention comprises a third sector gear at one end of a second transmission rod, a first sector gear at the other end of the second transmission rod, a first transmission threaded rod at the lower end of one outer side of the third sector gear, and a second transmission threaded rod at the lower end of the other outer side of the first sector gear. After the output motor outputs power and drives the second transmission rod to rotate, the rotation of the second transmission rod simultaneously causes the first and second transmission gear rings to rotate. The rotation of the second transmission gear ring can generate relative motion with the first transmission threaded rod, and the rotation of the first transmission gear ring can generate relative motion with the second transmission threaded rod. The relative motion of the rods, with both ends simultaneously moving relative to each other and mutually restricting each other, causes the device's storage bucket, first protective frame, second protective frame, and internal transmission structure to move longitudinally. When the covering is rotated and lifted, the device's storage bucket, first protective frame, second protective frame, and internal transmission structure move from bottom to top. When the covering is placed to wrap the sowing position, the device's storage bucket, first protective frame, second protective frame, and internal transmission structure move from top to bottom, reducing friction between the covering and the soil surface, avoiding damage to the sown vegetable leaves, and preventing soil from sticking to the surface of the covering.

[0025] 2. This invention features a fourth columnar gear positioned at the front end of the third columnar gear, a fifth sector gear positioned at the middle of the upper end of the fourth columnar gear, and a sixth sector gear positioned on one side of the fifth sector gear. A first transmission rod is located at one end of the sixth sector gear. When the second transmission rod rotates counterclockwise and collects the covering material to complete the lifting action, the second transmission rod directly drives the third sector gear to rotate counterclockwise. The third sector gear, through the fourth sector gear, drives the lower third columnar gear to rotate counterclockwise. The third columnar gear, through the fourth columnar gear, drives the fifth sector gear to rotate clockwise. The fifth sector gear, through the sixth sector gear, drives the first transmission rod to rotate clockwise. The rotating first transmission rod contacts the pulled covering material, and through friction, cleans the dirt adhering to the surface of the covering material, preventing dirt from adhering to the surface for extended periods, thus improving the service life of the covering material and preventing excessive dirt buildup inside the device.

[0042] The method for removing the covering device after leafy vegetable sowing includes the following steps:

[0043] Step 1: Start the output motor 12. The output shaft of the output motor 12 drives the second column gear 14 to rotate. The counterclockwise rotation of the second column gear 14 can drive the first column gear 13 to rotate clockwise. The first column gear 13 can directly drive the upper second sector gear 11 to rotate clockwise. The second sector gear 11 can drive the first sector gear 10 on the other side to rotate counterclockwise.

[0044] Step 2: The counterclockwise rotation of the first sector gear 10 can drive the second transmission rod 37 to rotate counterclockwise. The rotation of the second transmission rod 37 drives the clamping protrusions 29 on both sides of the upper outer end to rotate counterclockwise. The rotation of the clamping protrusions 29 can drive the placement cavity 32 to rotate counterclockwise. The placement cavity 32 will drive one end of the inner covering 9 to rotate counterclockwise. Continuous counterclockwise rotation can store the covering 9.

[0045] Step 3: The counterclockwise rotation of the second transmission rod 37 will drive the third sector gear 18 at one end to rotate counterclockwise. The third sector gear 18 will drive the fourth sector gear 19 at the lower end to rotate counterclockwise. The counterclockwise rotation of the fourth sector gear 19 will drive the third column gear 20 at the lower end to rotate counterclockwise. The third column gear 20 will drive the second transmission gear ring 21 on one side to rotate. The clockwise rotation of the first column gear 13 will drive the first transmission gear ring 15 on the other side to rotate. The interior of the first transmission gear ring 15 and the exterior of the second transmission threaded rod 5 will move relative to each other due to rotation. The interior of the second transmission gear ring 21 and the exterior of the first transmission threaded rod 4 will also move relative to each other due to rotation. After the first transmission threaded rod 4 and the second transmission threaded rod 5 are mutually restricted, the second transmission gear ring 21 and the first transmission gear ring 15 will move longitudinally upward under the support of the second connecting plate 23 and the first connecting plate 17, respectively. The longitudinal upward movement completes the unveiling of the cover 9.

[0046] Step 4: The third column gear 20 drives the second transmission gear ring 21 to rotate, which in turn drives the fourth column gear 24 to rotate clockwise. The clockwise rotation of the fourth column gear 24 can drive the fifth sector gear 25 at the upper end to rotate clockwise. The clockwise rotation of the fifth sector gear 25 can drive the sixth sector gear 26 to rotate.

[0047] Step 5: The rotation of the sixth sector gear 26 can drive the first transmission rod 28 supported by the support frame 27 to rotate. The rotating first transmission rod 28 contacts the uncovered cover 9 and cleans the soil from the lower end of the cover 9 by rotating and rubbing.

[0048] Step 6: When the covering material 9 is discharged and placed over the sowing position, the output motor 12 starts and drives the second column gear 14 to rotate clockwise. After the rotation of the second column gear 14 is reversed through steps 1 to 3, the device's storage bucket 1 moves vertically downward while discharging the covering material 9, actively completing the covering of the sowing position.

7. A method for removing the covering device after leafy vegetable sowing as described in claim 6, characterized in that: The steps include the following: Step 1: The output shaft of the output motor (12) drives the second column gear (14) to rotate. The rotation of the second column gear (14) can drive the first column gear (13) to rotate. The first column gear (13) can directly drive the upper second sector gear (11) to rotate. The second sector gear (11) can drive the first sector gear (10) on the other side to rotate. Step 2: The rotation of the first sector gear (10) can drive the second transmission rod (37) to rotate. The rotation of the second transmission rod (37) drives the clamping protrusions (29) on both sides of the upper outer end to rotate. The rotation of the clamping protrusions (29) can drive the placement cavity (32) to rotate. The placement cavity (32) will drive one end of the inner cover (9) to rotate counterclockwise. Step 3: The rotation of the second transmission rod (37) will drive the third sector gear (18) at one end to rotate. The third sector gear (18) will drive the fourth sector gear (19) at the lower end to rotate. The rotation of the fourth sector gear (19) can drive the third column gear (20) at the lower end to rotate. The third column gear (20) can drive the second transmission gear ring (21) on one side to rotate. The rotation of the first column gear (13) can drive the first transmission gear ring (15) on the other side to rotate. After the mutual restriction of the first transmission thread rod (4) and the second transmission thread rod (5), the second transmission gear ring (21) and the first transmission gear ring (15) move longitudinally upward under the support of the second connecting plate (23) and the first connecting plate (17), respectively. The longitudinal upward movement completes the unveiling of the cover (9). Step 4: The third column gear (20) drives the second transmission gear ring (21) to rotate, which in turn drives the fourth column gear (24) to rotate clockwise. The clockwise rotation of the fourth column gear (24) can drive the fifth sector gear (25) at the top to rotate clockwise. The clockwise rotation of the fifth sector gear (25) can drive the sixth sector gear (26) to rotate. Step 5: The rotation of the sixth sector gear (26) can drive the first transmission rod (28) supported by the support frame (27) to rotate. The rotating first transmission rod (28) contacts the uncovered cover (9) and cleans the side of the cover (9) in contact with the soil by rotating and rubbing. Step 6: When the covering material (9) is discharged and covered to the sowing position, the output motor (12) starts and drives the second column gear (14) to rotate clockwise. After the rotation of the second column gear (14) is reversed through steps one to three, the device storage bucket (1) moves vertically downward while discharging the covering material (9), and actively completes the covering of the sowing position.
