Description

Technical Field

[0001] The invention relates to the field of tobacco leaf planting, in particular to a tobacco leaf auxiliary picking device. Background Art

[0002] When picking tobacco leaves, due to the different maturity of tobacco leaves at different heights, the closer to the upper side, the lower the maturity. Therefore, in order to ensure the quality of tobacco leaves, the mature tobacco leaves at the lower side are usually picked first, and the upper side tobacco leaves are picked after they mature. Since manual picking is costly, time-consuming and labor-intensive, tobacco leaf picking equipment is currently used for auxiliary picking. For example, the scissor-type tobacco leaf layering picking mechanism disclosed in announcement number CN116235697A controls the lifting of the scissor-type mechanism by a circuit to achieve the cutting of the tobacco leaves by a ring knife. However, Some tobacco leaf picking equipment has the following defects: 1. The cost and threshold of circuit control are high, making it difficult to invest in actual production in large quantities; 2. The scissor mechanism itself has a certain height, which can easily block the tobacco leaves and cause them to break during movement, and the lowest cutting point is too high, making it difficult to effectively cut the bottom layer of tobacco leaves; 3. Since the growth status of each tobacco seedling is different, the height of mature tobacco leaves is also different, and the existing tobacco leaf picking equipment cannot adaptively adjust the cutting height; 3.

When the front and rear sliding rods 9 move left and right, they can respectively drive the sliders 5 on the left and right sides to move up and down.

[0029] A horizontally placed guide rod 10 is fixed to each of the front and rear ends of the U-shaped cutter 6, and a plurality of inclined rods 11 are evenly distributed on the guide rod 10 from front to back. The inclined rods 11 are arranged perpendicular to the guide rods 10 and the outer ends are inclined downward; a clearance groove 12 is opened on the base plate 1 at a position corresponding to each inclined rod 11, and when the swing rod 4 swings outward, the inclined rod 11 can be placed in the clearance groove 12.

[0030] A slide groove 13 is provided on the inner end surface of each of the swing rods 4, and the slider 5 is placed in the slide groove 13 and can slide up and down. A through hole 14 is provided on the swing rod 4 on the outer side of the slide groove 13 and penetrates the swing rod 4 along the length direction.

[0032] The baffle 19 is fixed at the inner end of the two base plates 1, and the baffle 19 can prevent the swing rod 4 from swinging inward from the vertical direction. The base plate 1 is located at the lower side of the swing rod 4 and has a clearance opening, and the first pull rope 17 can pass through the clearance opening to the lower side of the base 1.

[0033] A vertical plate 20 is fixed to the outer side of the two bottom plates 1, and a through groove 21 penetrating the left and right end surfaces is opened in the middle of the vertical plate 20. The swing rod 4 can be placed in the through groove 21 when it swings outward.

A shift rod 24 that can rotate in the horizontal direction is respectively provided on the lower side of the two baffles 19. In the absence of external force, the free end of the shift rod 24 always faces inward. When the shift rod 24 swings back and forth, it can drive the pin 23 to move toward the inside of the pin hole.

[0034] The gear lever 24 is an L-shaped rod, and the vertical rod part is a rotating shaft. Two third pull ropes 25 are fixed to the vertical rod part of each gear lever 24. The third pull ropes 25 are respectively wrapped around the inner end of the base plate 1 to the front and rear sides of the base plate 1, and pass through the vertical plate 20 to the pin shaft hole 22 and are fixedly connected to the pin shaft 23. A compression spring is arranged between the pin shaft 23 and the pin shaft hole 22, and the compression spring ensures that the pin shaft 23 always extends out of the pin shaft hole 22.

[0035] The connecting rod 8 is provided with a through slot penetrating the front and rear end surfaces, and the slide bar 9 is placed in the through slot and can slide left and right along the through slot.

[0036] Two groups of front and rear rollers 26 are arranged on the outer side of the bottom plate 1 .

[0037] The hinged position of the swing rod 4 is provided with a torsion spring, which ensures that the free end of the swing rod 4 is always located in the through slot 21 when no external force is applied. The torsion force of the torsion spring is much smaller than the tension force of the tension spring at the lower end of the slider 5.

[0038] It is worth mentioning that, in order to facilitate the reversing of the first pull rope 17 , a reversing wheel is provided at the free end of the swing rod 4 , and the first pull rope 17 bypasses the annular wheel and enters the through hole 14 .

[0039] The front and rear sides of the inner ends of the two bottom plates 1 are both beveled edges, so that the interval between the two bottom edges 1 is wide at both ends and narrow in the middle, which is convenient for tobacco seedlings to enter the interval area between the two bottom plates 1.

[0040] The third pull rope 25 is located at the front and rear sides of the bottom plate 1 and is respectively fixed with a pull net 27 , the lower end of the pull net 27 is fixed to the bottom plate 1 , and the pull net can prevent the collected tobacco leaves from falling from the front and rear sides of the bottom plate 1 .

[0041] When the present invention is in use, the handrail 7 is first used to push the device as a whole to the position of the tobacco seedlings, and the device as a whole is moved forward so that the tobacco seedlings enter the middle of the device through the interval between the two bottom plates 1. At this time, the stems of the tobacco seedlings on the lower side touch the gear lever 24 to make it swing backward, and the gear lever 24 drives the pin shaft 23 to move inwardly of the pin shaft hole 22 through the third pull rope, and the pin shaft 23 does not block the swing rod 4 from swinging inwardly, and then the slide bar 9 is manually pulled toward the position of the handrail 7, and the slide bar 9 drives the second winding wheel 16 to rotate through the second pull rope 18, and the second winding wheel 16 drives the first winding wheel 15 to rotate synchronously through the gear, and the first winding wheel 15 drives the swing rod 4 to swing inwardly through the first pull rope 17 to overcome the torsion force of the torsion spring, until the swing rod 4 swings to the vertical position and is blocked by the baffle 19. At this time, the two The U-shaped cutter 6 is just located outside the stem of the tobacco seedling plant. The slide bar 9 is continuously pulled, and the slide bar 5 can overcome the tension of the tension spring and move upward along the slide slot 13. During the upward movement of the slide bar 5, the upper blade of the U-shaped cutter 6 can cut the tobacco leaves passing through. The translation distance of the slide bar 9 can be changed according to the height position of the mature tobacco leaves to control the rising height of the U-shaped cutter 6. The cut tobacco leaves fall onto the bottom plates 1 on both sides under the guidance of the guide rods 10 and the inclined rods 11. After completing the cutting of one tobacco leaf, the slide bar 9 is released, and the swing rod 4 and the U-shaped cutter 6 can be reset to the initial position under the action of the torsion spring and the tension spring. The swing rod 4 does not block the upper tobacco leaves, and the device continues to move forward as a whole to the position of the next tobacco seedling, and the above operation is repeated to continue cutting the tobacco leaves. When a certain amount of tobacco leaves are collected on the bottom plate 1 and the gear lever 24 is in the initial position, the slide bar 9 can be directly pulled. At this time, the swing arm 4 cannot swing upward due to the obstruction of the pin shaft 23, but the slide bar 5 can still move upward along the slide groove 13. During the movement of the slide bar 5, all the inclined rods 11 can move outward along the give way groove 12, pushing and gathering the tobacco leaves collected on the bottom plate 1, ensuring that the tobacco leaves that are cut and dropped later can continue to be received by the bottom plate 1, thereby increasing the collection amount of the bottom plate 1.

[0042] The present invention replaces the electric control equipment with a mechanical structure, lightens the equipment and avoids the limitation of the environment on the circuit. By manually operating the slide bars 9 on the front and rear sides, the rising height of the cutter can be adjusted at any time according to human will, and mature tobacco leaves of different heights can be cut, which greatly improves the cutting quality of tobacco leaves. The swing bar 4 is located at the outermost side when the device is in the moving state, so as to avoid the interference of the swing bar 4 with the tobacco leaves during the movement. During cutting, it can swing inward to a vertical state, so as to ensure that the U-shaped cutter 6 can be located outside the plant, so that the slide bar 5 can cut the tobacco leaves by moving up and down along the slide groove 13. Compared with the telescopic cutting method of the scissor mechanism in the prior art, the interference of the equipment with the tobacco leaves is reduced while the lower limit of the cutting height is reduced. The guiding effect of the inclined rod 11 can make the cut tobacco leaves fall uniformly above the base 1, and the tobacco leaves are collected in a centralized manner, so as to solve the problem that the cut tobacco leaves still need to be picked up manually. Pulling the slide bar 9 in the non-cutting operation state can make the inclined rod 11 move horizontally along the give way groove 12 to comb the collected tobacco leaves to both sides, so as to improve the efficiency of collecting tobacco leaves.
