Description

Technical Field

[0001] The utility model relates to the technical field of mulberry leaf picking, in particular to a mulberry leaf picking device. Background Art

[0002] Mulberry leaves are a daily food for silkworms and a medicinal herb with high economic and medicinal value. Harvesting mulberry leaves requires leaving the petiole intact and carefully preventing damage to the buds hidden at the base of the petiole, which could reduce the tree's yield the following year. Therefore, harvesting mulberry leaves is a laborious and tiring task.

[0003] Traditionally, mulberry leaf plucking is still primarily done by hand, where individuals manually pick leaves one by one. This process is time-consuming, labor-intensive, inefficient, and prone to hand injuries. This method consumes significant labor and time, resulting in high costs. In today's socioeconomic environment, manual plucking is clearly no longer suitable for the development of silkworm farming and mulberry cultivation.

[0004] A Chinese utility model patent with publication number CN 118058066 A discloses a quick mulberry leaf picker, which includes a picker shell, a handle fixedly connected to the outer surface of the picker shell, a branch clamping port on the outer surface of the picker shell, a material receiving port on the top of the picker shell, a collection assembly clamped to the bottom of the picker shell, a start switch provided on the inside of the handle, a fixed blade fixedly connected to the inside of the picker shell, and a movable blade slidably connected to the inside of the picker shell. The present invention can quickly and conveniently cut mulberry leaf stems by arranging the fixed blade and the movable blade in combination.

[0005] Regarding the related art mentioned above, the inventors believe that the following defects exist: the picker housing in the above-mentioned device is cylindrical, and the branch opening is a fixed-size opening opened vertically. When picking mulberry leaves, it is necessary to align the branch opening with the mulberry branches and completely lock the mulberry branches inside. Then, the picker housing is moved upward, and the fixed blade and movable blade cooperate to pick the mulberry leaves into the collection assembly. However, due to the lush growth of mulberry branches, some branches grow diagonally, and some adjacent branches are close together. As a result, when the branches are locked into the branch opening, the picker housing will interfere with the surrounding branches. This requires manual cooperation to guide the branches, which not only increases the labor intensity of workers but also reduces picking efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely; obviously, the described embodiments are only a part of the embodiments of the present application, and not all the embodiments of the present application; based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0025] As shown in Figure 1-6 The present application discloses a mulberry leaf picking device, which comprises a handle 10, a driving assembly 50 and a collecting half-shell 20. The collecting half-shell 20 is used for picking and collecting mulberry leaves. The handle 10 is a C-shaped hollow structure, which is used for being held by a worker and driving the two collecting half-shells 20 to open or close through the driving assembly 50.

[0026] Specifically, the collecting half-shell 20 is a half-cylindrical structure, which comprises a bottom plate 21. The edge of the bottom plate 21 is sequentially provided with a first surrounding wall 22, a second surrounding wall 23, a third surrounding wall 24 and a fourth surrounding wall 25. The side edges of the first surrounding wall 22, the second surrounding wall 23, the third surrounding wall 24 and the fourth surrounding wall 25 are sequentially connected to form a closed surrounding wall, which cooperates with the bottom plate 21 to form a half-cylindrical structure. When arranged, the first surrounding wall 22 is a vertical surface, which is located on the side of the two collecting half-shells 20 that is adjacent to each other. In this way, when the two collecting half-shells 20 are closed, the first surrounding walls 22 of the two collecting half-shells 20 can be attached together, so as to ensure that the two collecting half-shells 20 are closed in place. The second surrounding wall 23 is a quarter of a circular arc surface, which is located on the side of the first surrounding wall 22 that is away from the other collecting half-shell 20. In this way, after the two collecting half-shells 20 are closed, a semicircular shape is formed. The third surrounding wall 24 and the fourth surrounding wall 25 are both curved surfaces, and the connecting line of the third surrounding wall 24 and the fourth surrounding wall 25 is an inclined line that extends upward. In this way, the third surrounding wall 24 and the fourth surrounding wall 25 form a beak-shaped structure at the front end of the collecting half-shell 20 after being enclosed. This facilitates the insertion of the collecting half-shell 20 into the branches of a mulberry tree. Therefore, when in use, only the beak-shaped end of the collecting half-shell 20 needs to be inserted into the branch to be picked. Since this end is beak-shaped, the front side and the inner side of the collecting half-shell 20 are both inclined inward. Therefore, only the beak-shaped part of the collecting half-shell 20 contacts the branch when the collecting half-shell 20 cooperates with the branch. This effectively reduces the contact between the collecting half-shell 20 and the surrounding branches, so that the branches do not need to be separated by workers, thereby improving the picking efficiency and reducing the labor intensity.

[0027] A relief groove 26 is provided on the fourth wall 25 of the collecting half-shell 20. A C-shaped plate 27, opening toward the relief groove 26, is provided on the inner side of the fourth wall 25, and a guide hole 28 is provided horizontally on the C-shaped plate 27. A semi-annular fixing plate 30 is provided on the side of the opening of the C-shaped plate 27 at the relief groove 26. When the two collecting half-shells 20 are closed, the two fixing plates 30 close together to form a complete ring, thereby embracing the harvested branches. A guide post 32 is provided on the fixing plate 30, protruding toward the C-shaped plate 27. The guide post 32 passes through the guide hole 28, and a compression spring 33 is sleeved on the guide post 32 between the C-shaped plate 27 and the fixing plate 30. The guide post 32 cooperates with the guide hole 28 to slide the fixing plate 30 onto the C-shaped plate 27, and the compression spring 33 elastically secures the fixing plate 30. When the branches being picked are thick or have knots, the fixing plate 30 can be moved inward by compressing the spring 33 to avoid damage to the branches caused by rigid contact. A limit plate 34 is provided at the end of the guide column 32 passing through the C-shaped plate 27 to prevent the fixing plate 30 from falling off the C-shaped plate 27.

[0028] A semi-annular blade 31 with an upward-facing blade is provided on the upper side of the fixing plate 30. When the two fixing plates 30 are closed together to form a complete ring, the two blades 31 are also closed together to form a complete ring. In this way, after the two collecting half shells 20 are closed, the two collecting half shells 20 are manually moved upward, and the mulberry leaves on the branches can be cut off by the two blades 31. The cut mulberry leaves can just fall into the two collecting shells, and the mulberry leaves on a branch can be picked by sequential movements. When the mulberry leaves in the collecting shell reach a certain amount, the mulberry leaves in the collecting shell can be poured into the mobile phone device.

[0029] In order to reduce damage to the buds at the base of the petiole when picking mulberry leaves, a semi-annular rubber gasket 35 is provided on the inner side of the fixing plate 30. The rubber gasket 35 contacts the branches and provides flexible protection for the branches and the buds at the base of the petiole.

[0030] Furthermore, the two collecting half-shells 20 are connected at the second surrounding walls 23 by a hinge 40. Specifically, the two hinges of the hinge 40 are fixed to the second surrounding walls 23 of the two collecting half-shells 20, respectively, and the hinge axis of the hinge 40 is located exactly between the two collecting half-shells 20, so that the two collecting half-shells 20 can rotate relative to the hinge axis of the hinge 40. Both hinges of the hinge 40 are provided with a mounting plate 41, and a fixing column 42 is provided on the mounting plate 41. The fixing column 42 is driven by the driving assembly 50 to move, thereby driving the hinge 40 to open or close.

[0031] The driving assembly 50 comprises fixed blocks 51 arranged at the upper and lower ends of the handle 10, and a sliding groove 52 is formed in the top surface of each fixed block 51 downwardly, and a sliding block 54 is arranged in the sliding groove 52. A driving hole 53 is formed in the side surface of each fixed block 51 close to the handle 10, and the driving hole 53 is in communication with the driving slot. A driving rod 56 is arranged on the side surface of the sliding block 54 close to the driving hole 53 and protrudes towards the driving hole 53, and the driving rod 56 extends to the vertical rod part of the handle 10 at the end away from the sliding block 54. The ends of the two driving rods 56 away from the sliding block 54 are connected by a connecting rod 57, so that the two sliding blocks 54 can be simultaneously driven to slide in the sliding grooves 52 by the connecting rod 57. When arranged, a button block 58 is arranged on the connecting rod 57, and a sliding hole 11 is formed in the vertical rod part of the handle 10 in correspondence, and the button block 58 is arranged in the sliding hole 11, so that the connecting rod 57 can be driven to move by pushing the button block 58.

[0032] A connecting shaft 55 is arranged vertically on the top surface of the sliding block 54, and two connecting plates 59 are rotatably connected to the connecting shaft 55, and the ends of the two connecting plates 59 away from the connecting shaft 55 are rotatably connected to the fixed columns 42 of the two hinges of the hinge hinge 40. Thus, when the sliding block 54 moves along the sliding groove 52 towards the collecting half-shell 20, the two hinges of the hinge hinge 40 are pushed open by the two connecting plates 59, thereby driving the two collecting half-shells 20 to open; when the sliding block 54 moves along the sliding groove 52 towards the handle 10, the two hinges of the hinge hinge 40 are pushed together by the two connecting plates 59, thereby driving the two collecting half-shells 20 to close. In order to prevent the connecting plates 59 from being separated from the connecting shaft 55, a limiting circular plate 551 is arranged on the top of the connecting shaft 55.

[0033] The operating principle of a mulberry leaf picking device in this embodiment is as follows: when in use, a worker holds the handle 10 and pushes the button block 58 toward the collecting half shell 20, and drives the driving rod 56 to move toward the collecting half shell 20 through the connecting rod 57, thereby pushing the slider 54 and the connecting shaft 55 to move toward the collecting half shell 20, and pushes the two hinges of the hinge 40 to open through the two connecting plates 59, driving the two collecting half shells 20 to open a certain gap; then the pointed sections of the two collecting half shells 20 are aligned with the branches to be picked and move toward the branches, so that the branches enter the openings of the two fixing plates 30 The worker then pushes the button block 58 away from the collecting half-shell 20, driving the driving rod 56 away from the collecting half-shell 20 via the connecting rod 57, thereby pushing the slider 54 and the connecting shaft 55 away from the collecting half-shell 20. The two hinges of the hinge 40 are pushed together via the two connecting plates 59, driving the two collecting half-shells 20 to close, and the two fixing plates 30 to wrap the branches. The worker then holds the button block 58 in place with his fingers and moves the collecting half-shell 20 toward the top of the branch using the handle 10. The mulberry leaves are picked into the collecting half-shell 20 under the action of the blade 31. The worker can operate the tool with one hand, which is simple to operate. The pointed tip of the collecting half-shell 20 makes it easy to locate the branch and quickly insert it into the branch, resulting in high picking efficiency.
