Abstract

PROBLEM TO BE SOLVED: To provide a weed pulling apparatus capable of continuously performing pinpoint weed pulling in a standing posture without imposing a burden on a body and arms, and continuously removing viscous soil and weeds after pulling out the weeds from the apparatus only with hand operation, and continuously pulling out the weeds.SOLUTION: A turning claw 4 journaled at the upper part of a preceding claw 5 and turned by a spring 8 to be releasable nips and holds grass with the operation of a lever at an other end of the turning claw. When culm 1 is pulled out of the ground, a kicker 7 having a surface substantially perpendicular to the preceding claw for holding a pinpoint weed root, and pushed down to the lower end of the preceding claw by a spring 9, presses down the pulled-out weeds toward the lower end direction of the turning claw. When the turning claw is then released by lever operation, the pulled-out weeds are released, and simultaneously a bottom part of the kicker can discharge the weeds out of an apparatus in an instant from the inside of a turning part. Further, the bottom face of the kicker can remove soil and weeds sticking to the apparatus with an impact of a sudden stop at the lower end of the preceding claw.

Description

  The present invention relates to a weeding apparatus that can continuously weed by a simple operation of pushing, grasping, pulling, and releasing in a standing posture and with only one hand without placing a burden on the body.

  In an aging social situation, weeding the lawns in Lynx and the mansion requires a long time in a squatting or sitting position, which puts a heavy burden on the body. In such a background, it has been highly desired that weeding can be performed continuously while standing and without requiring excessive force on the body and arms.

  None   None

  At present, there are devices that extract grass over a wide range, and devices that pull grass by sitting or crouching, but there are no devices that have a function that allows pinpoint grass such as lawn to be placed without burdening the body.

  Since the present invention has made it possible to remove the weed with only a force that is substantially perpendicular to the ground in a standing posture without imposing a burden on the body, it is presented here as the present invention.

  The present invention is presented as the present invention because the extracted grass and the like can be released by the chain action by loosening the lever, and the weeding can be continuously performed.

A handle and lever are provided at the top of the housing, and a leading claw and a rotating claw are provided at the bottom of the housing, aiming at pinpoint grass with a force substantially perpendicular to the ground, and sandwiching the grass in a saddle shape by lever operation After lifting the frame and removing the grass and holding it securely, it becomes possible to release the grass again by operating the lever, and pull out the pinpoint grass without placing a burden on the body or arms while standing. be able to.

  The kicker having a surface substantially perpendicular to the preceding claw sliding on the side surface of the preceding claw is spring-engaged with the casing in the downward direction and the rotating claw is opened in the spring direction. The bottom of the kicker is moved to the lower end of the leading claw, and the rotating claw is urged in the direction to open from the side of the leading claw. When the rotating claw is released by lever operation after the grass has been reliably pinched and held in the state, and the lever is operated, the grass can be reliably discharged from the inside of the turning claw curve. Also, when the bottom of the kicker stops at the lower end of the leading claw, it is easy to release viscous soil and grass from the device, and weeding is continued without removing the soil and grass attached to the device. be able to.

  The rotating claw with the rotation fulcrum at the top of the leading claw at the tip of the chassis is connected to the lever at the top of the chassis with the other end with an engagement cable etc. It can be reliably pulled out only by lifting the housing.

  The kicker that slides on the side surface of the previous nail and forms a substantially right-angled surface with the previous nail is spring-engaged with the specific part of the housing, and the lever is operated to move the grass on the side surface of the previous nail, inside the turning nail curve, and on the bottom of the kicker. By holding it securely in the saddle shape and lifting the housing, it is possible to remove it without placing any special burden on the body.

  When the rotating claw is released by the lever, the rotating claw is instantaneously separated from the side surface of the preceding claw by the spring, and the undissolved kicker bottom surface releases the extracted grass. At this time, when the bottom of the kicker is returned to the tip of the leading nail and stops, the soil and grass that adhere to the equipment can be automatically released, enabling continuous weeding. Can do.

  After the grass is sandwiched between the leading claw, the rotating claw and the kicker in the weeding device composed of the leading claw, the rotating claw and the kicker provided at the lower end of the cabinet, the casing is It is characterized by the fact that the grass is lifted and removed, and then the grass is pushed out and released from the device with kicker when the rotating claw is released, removing the adhesion of grass and soil, and enabling continuous weeding.

1 and 2 show an embodiment of the present plan. In the present invention, a handle 2 is attached above the housing 1 at a substantially right angle thereto, and the position can be changed according to the height of the user. Further, a rotatable lever 3 pivotally supported at the tip of the handle 2 is attached. The lever 3 is pivotally supported by a preceding claw 5 with a rotating claw 4 that is engaged by a cable 6 that penetrates the inside of the housing 1 downward. The claw head and kicker 7 of the rotating claw 4 having a saw blade at the lower tip that is pivotally supported by the upper part of the leading claw 5 having a rounded tip have a spring engagement with the housing 1. The connection with the lever 3 is attached to be adjustable with screws.
Further, a kicker 7 having a guide hole capable of moving the leading claw 5 up and down and having a surface substantially perpendicular to the preceding claw 5 is slidably attached to the preceding claw 5. The kicker 7 is provided with a stopper so as to stop at the lowermost end of the leading claw 5. The head of the rotating claw 4 is tensioned and engaged with the preceding claw 5 by the rotating claw spring 8 and is always urged away from the surface of the preceding claw 5, and the bottom surface of the kicker 7 is It is urged to press against the tip of.
Now, holding the handle 2 at the top of the housing 1, pressing the bottom of the kicker 7 on the grass to be pulled out, and piercing the leading claw 5 into the ground, the kicker spring 9 Due to the applied force, the surface of the kicker enters the inside of the curve of the rotating claw 4. Next, by grasping the handle 2 and the lever 3 at the top of the housing 1, the rotating claw 4 rotates by rotating the rotating claw spring 8, and the tip blade portion of the rotating claw 4 presses against the surface of the preceding claw 5. It is in a state where the root part of the grass is sandwiched. The grass can be pulled out by lifting the handle 2 in this state. When the leading claw 5 comes off from the ground, the removed grass can be pressed against the tip of the turning claw 4 inside the turning claw 4 by the return force of the kicker spring 9, and the removed grass can be securely held in a bowl shape. .
When the lever 3 is released, the grass is released from the side wall of the leading claw 5 by the return force of the kicker spring 9. Prior to that, the rotating claw 4 has released the hook-shaped holding by the spring force. Further, the soil or grass with viscosity can be removed by the sudden stop and release force at the tip of the leading claw 5 on the bottom surface of the kicker 7.
From the above, pinpoint weeding can be performed in a standing posture without applying excessive force to the body or arm with only a force in a substantially vertical direction against the ground. Further, it is possible to prevent soil and grass from adhering due to the viscosity of the soil and grass, and to continuously remove the grass without removing the deposits.
