JP3215828U - Thick metal pipe rod weed extractor for impact driver - Google Patents

Abstract

An object of the present invention is to provide a weed removal tool that improves the durability of the tool itself, reduces resistance reaction force from the soil, suppresses battery consumption, and can perform work with a power tool for a long time. A main material portion obtained by cutting a cutting edge parallel to the longitudinal direction of a pipe at a lower end tip portion of a thick metal pipe rod, and a hexagonal bit for an impact driver are joined and combined at the upper end portion. The durability of the tool itself is improved, and the rotational force is transmitted only in the circumferential direction of the pipe cutting edge, so that the resistance reaction force from the soil is reduced and the burden on the electric motor is also reduced. Moreover, since the pressurization part between the instrument main body and the ground is difficult to break, a strong impact force and high-speed rotation can be applied even to a weed root having a high resistance strength.

Description

  The present invention has a strong impact force against weed roots by combining a main metal part with cutting edge processing at the lower end tip of a thick metal pipe rod and a hexagonal bit for impact driver at the upper end part. And a high-speed rotation, and a device for weed removal equipment for performing the conventional weed removal operation more easily.

  About conventional weed removal tools for electric tools (hereinafter referred to as “conventional tools”), the structure is generally a little complicated or plastic molding is used a lot, and there is anxiety about strength, and the tools themselves do not last long There was a drawback. Also, due to the unique shape of the tool, the rotational reaction force from the ground was large, the electric tool was burdened on the motor, and the battery was consumed due to the heavy load, making it unsuitable for long hours of work. (For example, see Patent Document 1)

JP2011-050305A

  The present invention alleviates the disadvantages of conventional devices, such as “damage and wear of the device due to insufficient strength of the device” and “consumption of the charging battery voltage due to resistance load from the soil”. The purpose is to “work out weeds in time”.

  In order to solve the above-mentioned problems, the main material part with the cutting edge processed at the lower end tip of the thick metal pipe rod and the hexagonal bit for impact driver are joined and combined with the upper end part. The point is solved.

  By this device, the durability of the instrument itself is improved, and since the rotational force is transmitted only in the circumferential direction of the pipe blade tip, the resistance reaction force from the soil is reduced, so the impact driver can be applied to the electric motor. The burden is also reduced, thereby reducing battery consumption, and weeding work with a power tool can be performed for a long time.

  By this device, the material of the blade edge part is a thick metal pipe rod, so the structure is simple and rigid, so the pressure part between the instrument body and the ground is less likely to break compared to conventional instruments. The impact driver's strong impact force and high-speed rotation can be applied to high weed roots, and various weed removal operations that were difficult with conventional tools can be performed in a wider range.

It is a detailed view of the present invention. It is the schematic at the time of use of this invention.

    FIG. 1 is a detailed view of the structure of the device according to the present invention, in which a main material portion obtained by cutting a cutting edge at the lower end tip portion of a thick metal pipe rod, and a hexagonal bit for an impact driver at the upper end portion. In the combined use, it is used with an impact driver attached to the hexagonal bit part in actual use.

  As an example of use of the device of the present invention, an impact driver is attached to the hexagonal bit portion (2), and the impact driver is switched on with the blade tip portion (3) being lightly stabbed into the root of the weed. Weed roots are entangled by rotating the whole at high speed.

Effects of the embodiment

  The integrated blade edge shape improves the durability of the tool itself, and the rotational force is transmitted only in the circumferential direction of the pipe blade edge, reducing the resistance reaction force from the soil. The burden on the motor is also reduced, thereby reducing battery consumption, and weeding work can be performed with a power tool for a long time. Compared with the conventional instrument, the pressure part between the instrument body and the ground is less likely to break, so it is possible to give the impact driver strong impact force and high-speed rotation against weed roots with high resistance strength. Various weed removal operations that were difficult to do can be performed in a wider range.
