Description

Fallen leaf picker

Technical Field

The invention relates to the technical field of garden green land sanitation and sanitation, in particular to a fallen leaf picker.

Background

In winter every year, a large amount of leaves of many trees fall in a short period, so that the environmental sanitation of gardens, greenbelts, streets and the like is deteriorated. In general, a tool for sweeping fallen leaves is usually used to sweep the fallen leaves together under a tree crown beside a garden, a road and the like, or enter a lawn, a public green land and other places to sweep the fallen leaves to a small pile, and then remove the pile with a garbage shovel. When a rake or a broom is generally used for sweeping fallen leaves, the ground is required to be relatively flat or the ground vegetation is mainly lawn, and in most cases, workers need to enter the interior of a green land for sweeping. However, in some garden greens, it is not suitable to use a rake of general specification to clean due to the vegetation type and growth state of the fallen leaves, and it is difficult for the cleaning personnel to clean inside to protect the vegetation from trampling. For example, a lot of fallen leaves are piled in the open space inside the grasses or shrubs under the tree crown, the void area in the middle of the grasses or shrubs is small and irregular, and the common grass rake is difficult to clean.

Therefore, there is a high necessity for a fallen leaf picker to solve the above technical problems.

In the description of the present invention, it should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but the information should not be limited to these terms, and these terms are only used to distinguish one type of information from another. For example, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information, without departing from the scope of the present invention.

Referring to fig. 1-2, an embodiment of the present invention provides a fallen leaf picker, including an outer tube 1, a moving device 2, a pulling rope 3, a pulling rod 4, a tapered guide 5, an expansion member (not shown in the figure), and at least four claws 7, where the moving device 2 is disposed at a first end of the outer tube 1 and is used to pull the pulling rope 3, the pulling rope 3 and the pulling rod 4 are both disposed in the outer tube 1, a first end of the pulling rope 3 is connected to a first end of the pulling rod 4, and a second end of the pulling rope 3 is connected to the moving device 2; the second end of outer tube 1 is connected with toper guide 5 and toper guide 5 opening is downward, and the second end of pull rod 4 is connected with jack catch 7, and the junction of jack catch 7 and pull rod 4 still is equipped with the inflation piece for make jack catch 7 outwards open and butt toper guide 5's inner wall. It is worth noting that the expansion element is an element of the prior art, the purpose of which is to keep the jaws 7 always under outward tension, so that the jaws 7 always abut against the conical guide 5.

Based on the technical characteristics, the embodiment of the invention discloses a fallen leaf picker, wherein a moving device pulls a pull rope 3 or loosens the pull rope 3, when the pull rope 3 is stretched, a pull rod 4 moves upwards due to the elastic action of the pull rope 3, so that a clamping jaw 7 moves upwards, and due to the opening action of an expansion piece, the clamping jaw 7 is folded inwards along the inner wall of a conical guide piece 5 in the lifting process to clamp fallen leaves; when the pull rope 3 is loosened, the pull rod 4 moves downwards due to the elastic action of the pull rope 3, so that the claws 7 move downwards, and due to the opening action of the expansion piece, the claws 7 are expanded outwards along the inner wall of the conical guide piece 5 in the descending process, so that the clamped fallen leaves are loosened. The fallen leaves are clamped by the clamping jaws 7, so that the fallen leaves are removed in a small operating space range.

Preferably, still include spring 6 and limit baffle 8, limit baffle 8 is located in outer tube 1, and limit baffle 8 is worn to establish by pull rod 4, and on pull rod 4 was located to spring 6 cover, the up end butt limit baffle 8 of spring 6, lower terminal surface butt jack catch 7. Can be so that certain resistance when upward movement pull rod 4 through setting up spring 6, avoid the user to damage equipment, in addition, can also be when downward movement pull rod 4, because spring 6's elastic action, the lower extreme of pull rod 4 can move down and jack catch 7 outwards opens and loosen the fallen leaves, plays the supplementary effect of loosening.

Preferably, the moving device 2 comprises a fixed part 21 and a rotating part 22, the fixed part 21 is fixedly connected with the first end of the outer tube 1, one end of the rotating part 22 is rotatably arranged on the fixed part 21, and the rotating part 22 is fixedly connected with the pull rope 3. Therefore, when the pull rod 4 needs to be moved upwards, the rotating part 22 can be rotated anticlockwise (the rotating part 22 is held by hand to rotate anticlockwise), when the pull rod 4 needs to be moved downwards, the claws 7 can be opened outwards only by loosening the wrist under the action of the spring 6, and furthermore, the fixing part 21 and the rotating part 22 are provided with anti-skidding layers.

Preferably, the number of the claws 7 is four, and two adjacent claws 7 are arranged at the second end of the pull rod 4 at an included angle of 90 degrees, so that the falling leaves can be clamped more stably.

Preferably, the claw 7 comprises a crescent-shaped part 71 and a clamping part 72, one end of the crescent-shaped part 71 is fixedly connected with the second end of the pull rod 4, and the clamping part 72 is of a rough-surfaced structure and is arranged at the other end of the crescent-shaped part 71, so that the falling leaf clamping device can adapt to a smaller operation space and can stably clamp falling leaves.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
