Description

[0002] Sweet potato is a common food crop grown in northern my country. It has edible, medicinal, economic and breeding functions and has valuable value. During the cultivation process of sweet potato, in order to prevent the aerial roots on the sweet potato seedlings from continuing to provide nutrients to the sweet potato seedlings, thereby causing nutritional deficiency of the sweet potato itself, the sweet potato seedlings need to be lifted.

[0003] In the process of lifting the sweet potato seedlings, in order to ensure that the sweet potato seedlings will not occupy the nutrients absorbed by the sweet potatoes, it is usually necessary to manually lift and cut the sweet potato seedlings. After cutting the seedlings, the sweet potatoes will absorb fertilizer better. At the same time, the collected sweet potato seedlings can also be collected for easy consumption. However, manual lifting requires workers to frequently bend over to perform lifting and cutting operations, which is time-consuming and laborious. After lifting the seedlings, in order to avoid nutrient loss in the sweet potatoes themselves, manual fertilizer supplementation is required, which is inefficient.

The first vertical mounting plate 1 and the two second vertical mounting plates 2 form an I-shaped structure, and the two L-shaped mounting plates 3 are used to support the I-shaped structure; The upper ends of the horizontal plates of the two L-shaped mounting plates 3 are respectively detachably mounted with fertilizer barrels 6, and the two fertilizer barrels 6 are temporarily fixed on the two L-shaped mounting plates 3 by means of a clamping connection, and the lower ends of the two fertilizer barrels 6 are respectively mounted with fertilizer replenishing mechanisms, and the two fertilizer replenishing mechanisms are both arranged in the two first gaps, and the fertilizer replenishing mechanisms are used to replenish fertilizer for the soil for planting sweet potatoes, thereby avoiding time-consuming and labor-intensive manual fertilization; The lower ends of the vertical plates of the two L-shaped mounting plates 3 are respectively vertically mounted with horizontal mounting plates 4, and both ends of the two horizontal mounting plates 4 are respectively rotatably mounted with rollers 5; Handrails 7 are fixedly mounted on the rear walls of the horizontal plates of the two L-shaped mounting plates 3, respectively. The rollers 5 are used to support the entire device to move, and the handrails 7 are used to assist the device to move forward; The front and rear side walls of the first vertical mounting plate 1 are movably mounted with n-shaped mounting frames 12, and the two n-shaped mounting frames 12 are movably arranged between the two second vertical mounting plates 2, and the two n-shaped mounting frames 12 are used to mount the hook claws 23 described later; The two n-shaped mounting frames 12 are both driven to flip by the first flipping mechanism. An operating mechanism is installed on the top wall of the first vertical mounting plate 1. The n-shaped mounting frames 12 drive the hooks 23 to swing up and down under the drive of the first flipping mechanism to lift the sweet potato seedlings. The two first turning mechanisms are both driven to work by the operating mechanism; A plurality of hooks 23 are movably mounted between the ends of the two vertical rods of the same n-shaped mounting frame 12, and a second gap is left between the two adjacent hooks 23 on the same side. The n-shaped mounting frame 12 on the same side movably drives the plurality of hooks 23 close to it to rotate, and the hooks 23 can also rotate by themselves when the n-shaped mounting frame 12 drives the flipping, so that the seedlings can be further fixed after being lifted and pulled, so as to prevent them from falling off and affecting the subsequent cutting work; A plurality of tool holders 24 are movably mounted on the lower parts of the left and right side walls of the first vertical mounting plate 1, and a plurality of tool holders 24 located on the same side are movably mounted between the two second vertical mounting plates 2; A plurality of tool holders 24 are detachably arranged in a plurality of second gaps close thereto, and a plurality of tool holders 24 located on the same side are all driven to flip by the second flipping mechanism, and the two second flipping mechanisms are driven to work by the two first flipping mechanisms. The tool holder 24 can flip up and down under the drive of the second flipping mechanism. When the hook claw 23 pulls the seedling upward, the tool holder 24 drives the tool 2501 described later to rotate downward, providing a certain downward force for cutting; Cutters 2501 are slidably mounted on the front walls of the plurality of cutter racks 24, and the plurality of cutters 2501 on the same side are driven to slide by a sliding mechanism; The plurality of tool holders 24 on one side respectively drive the sliding mechanism on the same side to work by flipping. When the tool holder 24 drives the tool to flip downward, the sliding mechanism will also synchronously drive the tool 2501 to slide in the tool holder 24, ensuring that it has downward cutting pressure and a certain cutting force. The two fertilizer supplementing mechanisms are driven to work respectively by the two first turning mechanisms.

[0021] The fertilizer replenishing mechanism comprises a fixed barrel 601, a movable barrel 21, a first fixed block 20, a first connecting rod 15, and a first rectangular sliding block 13; The horizontal plates of the two L-shaped mounting plates 3 are respectively provided with round holes 301, and the lower ends of the two fertilizer barrels 6 are respectively connected with fixed barrels 601, and the two fixed barrels 601 are respectively arranged to penetrate the two round holes 301; The movable barrels 21 are slidably installed in the two fixed barrels 601, respectively, and the two movable barrels 21 are connected to the two fixed barrels 601 respectively; The first fixing blocks 20 are fixedly mounted on the outer walls of the two movable barrels 21, respectively. The two first fixing blocks 20 are movably disposed under the two fixed barrels 601. The first connecting frames 2001 are fixedly mounted on the inner walls of the two first fixing blocks 20, and the first ends of the first connecting rods 15 are rotatably mounted in the two first connecting frames 2001. The outer walls of the two second vertical mounting plates 2 are respectively provided with first rectangular slide grooves 202, and the two first rectangular slide grooves 202 are respectively provided under the horizontal plates of the two L-shaped mounting plates 3; The first rectangular sliding blocks 13 are slidably installed in the two first rectangular sliding grooves 202, and the second connecting frames 1301 are fixedly installed on the outer walls of the two first rectangular sliding blocks 13; The second ends of the two first connecting rods 15 are rotatably disposed in the two second connecting frames 1301 respectively; The two first rectangular sliders 13 are driven to slide by the two first flipping mechanisms respectively. The two first rectangular sliders 13 start to slide up and down along the first rectangular slide grooves 202 on both sides driven by the two first flipping mechanisms. In the process of sliding up and down, the two first rectangular sliders 13 respectively drive the first connecting rods 15 on both sides to start to deflect up and down. In the process of deflecting up and down, the two first connecting rods 15 respectively drive the first fixed blocks 20 on both sides to start to drive the movable barrels 21 fixedly connected thereto to start to slide up and down along the fixed barrels 601 on both sides. When the two movable barrels 21 slide downward and insert into the soil, the solid fertilizer in the fertilizer barrel 6 will enter the soil through the fixed barrel 601 and the movable barrel 21. When the movable barrel 21 slides upward, the upper end of the movable barrel 21 passes through the fertilizer in the fertilizer barrel 6 and is placed above the solid fertilizer. At this time, the solid fertilizer will not fall to the ground through the movable barrel 21.

[0022] The first flipping mechanism comprises a second connecting rod 14, a third connecting frame 29, a third connecting rod 16, a fourth connecting rod 12, and a second rectangular sliding block 11; The two sides of the two second vertical mounting plates 2 are respectively provided with first rectangular through grooves 201, and the first rectangular sliding groove 202 located on the same second vertical mounting plate 2 is arranged between the two first rectangular through grooves 201 adjacent thereto; The second rectangular sliding blocks 11 are slidably installed in the four first rectangular through grooves 201 respectively, and the same first rotating shaft is rotatably installed between the two second rectangular sliding blocks 11 located on the same side of the first vertical mounting plate 1; The horizontal plate of the n-shaped mounting frame 12 on the same side is fixedly sleeved on the first rotating shaft close thereto; A second rotating shaft is rotatably mounted between the two vertical rod ends of the two n-shaped mounting frames 12; The two ends of the second rotating shaft located on the same side respectively rotate to penetrate the two vertical rods of the n-shaped mounting frame 12 close thereto and fix the first end of the third connecting rod 16 thereon; A third rotating shaft is movably installed on both sides of the two first rectangular slide grooves 202, and the third rotating shafts located on both sides of the same first rectangular slide groove 202 are rotatably installed on the outer wall of the second vertical mounting plate 2 close thereto; The second ends of the two third connecting rods 16 are respectively rotatably sleeved on the third rotating shafts close thereto; A third connecting frame 29 is fixedly mounted at the middle of the upper ends of the four third connecting rods 16, and the first ends of the second connecting rods 14 are rotatably mounted in the four third connecting frames 29; Fourth connecting frames are fixedly installed on both sides of the two second connecting frames 1301, and the second ends of the four second connecting rods 14 are rotatably arranged in the fourth connecting frames close thereto; The four second rectangular sliding blocks 11 are all driven to slide by the operating mechanism; The four third rotating shafts drive the two second turning mechanisms to work by rotating respectively, and the two second rectangular sliding blocks 11 located on the same side begin to slide up and down along the first rectangular through grooves 201 close to them under the drive of the operating mechanism. During the process of sliding up and down, the two second rectangular sliding blocks 11 also begin to drive the n-shaped mounting frame 12 located therebetween to slide up and down. Since the cross bar of the n-shaped mounting frame 12 is rotatably mounted between the two second rectangular sliding blocks 11, with the cooperation of the third connecting rods 16 on both sides of the n-shaped mounting frame 12, when the n-shaped mounting frame 12 slides downward, the angle between it and the third connecting rods 16 on both sides becomes smaller, and the n-shaped mounting frame 12 begins to flip upward. When the n-shaped mounting frame 12 slides upward, the angle between it and the third connecting rods 16 on both sides becomes larger, and the n-shaped mounting frame 12 begins to flip downward. When the n-shaped mounting frame 12 slides downward and flips upward, the two vertical rods of the n-shaped mounting frame 12 tend to be horizontal and drive the hook claws 23 to approach the sweet potato seedlings. When the n-shaped mounting frame 12 slides upward and flips downward, the hook claws hook the seedlings and begin to pull them upward.

[0023] A first main shaft 22 is rotatably mounted between two vertical rods of the n-shaped mounting frame 12 located on the same side; The two first main shafts 22 are respectively fixedly mounted on the second rotating shaft fixed thereto, and a plurality of hooks 23 located on the same side are respectively fixedly mounted on the outer wall of the first main shaft 22 close thereto. Since the first main shaft 22 is fixedly connected to the second rotating shaft, and the second rotating shaft is fixedly connected to the third connecting rod 16, when the third connecting rod 16 is deflected, it will drive the first main shaft 22 to start rotating, and the plurality of hooks 23 fixedly connected to the first main shaft 22 will also have the ability to rotate at this time. When the n-shaped mounting frame 12 drives the hooks 23 to lift the seedlings upward, the hooks 23 also flip upward synchronously, further fixing the lifted sweet potato seedlings, facilitating subsequent cutting work.

The user turns the operating screw 8 to make the operating screw 8 start to rotate. During the rotation process, the operating screw 8 drives the third rectangular sliding block 10 threadedly penetrated therewith to start sliding up and down along the second rectangular through groove 101. The third rectangular sliding block 10 can drive the two n-shaped driving rods 9 fixedly connected thereto to start sliding up and down by moving up and down.

The two second spur gears 18 located at the same end can drive the second main shaft 19 fixedly installed therewith through rotation, so that the second main shaft 19 starts to rotate. At this time, the several tool holders 24 fixedly mounted on the second main shaft 19 have the ability to rotate. When the several hook claws located on one side pull the sweet potato seedlings upward and hook them to fix them, the several tool holders 24 located on the same side drive the tool 2501 matched with them to rotate downward to provide a certain force for cutting the seedlings.

The T-shaped slider 25 fixedly connected to the second fixed block 28 also begins to slide downward along the T-shaped slide groove 2401 at this time. The tool 2501 fixedly connected to the T-shaped slider 25 now has the ability to slide, which can ensure that it can slide while the tool rack 24 is flipped downward, thereby achieving the cutting effect on the sweet potato seedlings.

[0027] Implementation method of the present invention: The device is pushed to the surface of the sweet potato planting field, and when it is pushed above the sweet potato seedlings to be lifted, by rotating the operating screws 8, the n-shaped mounting frames 12 on both sides of the device begin to turn downward, and drive a plurality of hook claws 23 to gradually approach the sweet potato seedlings; As the hook 23 approaches the sweet potato vine, the movable barrels 21 on both sides of the device also sink into the soil to perform fertilization operation on the soil; After the hook 23 contacts the sweet potato vine, the operating screw 8 is rotated in the opposite direction, so that the n-shaped mounting frames 12 on both sides of the device begin to flip upward, and the hook 23 is driven by the n-shaped mounting frames 12 to hook the sweet potato vine and pull it upward. While pulling, the sweet potato vine is firmly hooked on the hook 23 as the hook 23 rotates; While the hook 23 hooks the sweet potato vines, several tool racks 24 located behind the hook 23 rotate downward synchronously, and several knives 2501 also begin to rotate downward under the drive of the tool rack 24 to press down the hooked sweet potato vines. As the tool rack 24 flips downward, the knives 2501 also slide synchronously at this time, and the sweet potato vines are cut with the cooperation of the downward pressure.

[0028] The n-shaped mounting frame of the present invention will drive the hook claw to flip up under the drive of the first flipping mechanism, and while flipping up, the hook claw will rotate upward to grasp the sweet potato vines, and while grasping, the tool holder located below the hook claw will synchronously rotate downward under the drive of the second flipping mechanism, providing downward pressure for cutting the sweet potato vines, and driving the tool to cut the grasped sweet potato vines in cooperation with the sliding mechanism. The fertilizer supplementation mechanism of the present invention will also perform a fertilizer supplementation operation on the soil where the sweet potatoes are buried while cutting the sweet potato vines, thereby better ensuring the growth of the sweet potato body.
