Abstract

(57) [Summary] [Structure] A drum rotor with a guard with an arc-shaped cross section attached to the end. [Effect] By installing the guard for protecting the holder at the end of the drum rotor of the management work machine, the impact at the time of operating the work machine is mitigated, and fatigue is remarkably reduced, which helps to alleviate mental tension. Further, the work on the side of the concrete ridge is facilitated and the service life of the drum rotor is extended, so that the maintenance cost of the management work machine can be reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drum rotor, and more specifically, a guard is attached to the end of the drum rotor of a management work machine to avoid direct contact with the concrete ridge of the drum rotor and protect the fixed holder of the claw at the end of the drum rotor. The drum rotor of the structure.

[0002]

[Problems to be solved by conventional techniques and devices]

 When the management work machine is used to cultivate the soil near the concrete ridge, scrape it, and weed it in the middle, the holder for fixing the claws at the end of the drum rotor is frequently damaged due to contact with the concrete. Therefore, it is desired to develop a management work machine having a structure in which the fixed holder is not damaged.

[0003]

[Means for Solving the Problems]

 The present invention relates to a drum rotor in which a guard having an arc-shaped cross section is attached to an end portion of a drum rotor of a management work machine.

The present invention will be described with reference to the drawings. FIG. 1 is a front view of a management work machine. A pair of drum rotors 3 and 3'attached to a drive unit 2 of a main body 1 are detachable, and the drum rotor itself is commercially available as a component. A plurality of claws 5 fixed by a holder 4 are attached to this drum rotor.

FIG. 2 is a partially enlarged view of the drum rotor, and a guard 6 is installed at the end of the drum rotor. The guard 6 protects the holder 4 for fixing the claw 5 at the end of the drum rotor to prevent abrasion and damage due to contact with a solid material such as a concrete ridge.

Therefore, the guard may be made of any material that is not easily worn or damaged by contact with these solid materials, and an iron plate is usually used. In addition to iron plates, hard materials such as engineering plastics can also be used. The size of the iron plate etc. used for the guard is a length that can be fixed (screwed, welded, etc.) to both ends of the drum rotor when it is formed into an arc shape, considering the model of the management work machine, especially the diameter of the drum rotor. It only has to be Similarly, the width of the iron plate and the like may be determined in consideration of the model of the management work machine, especially the diameter of the drum rotor, but it is usually about 3 to 6 cm, preferably 4 to 5 cm, and the thickness is 3 to About 7 mm is suitable. FIG. 3 shows one mode of a guard formed by molding an iron plate into a gentle arc shape having an arc height of 2 to 3 cm. Further, FIG. 4 shows a state in which the guard is attached to the drum rotor.

If the cross-sectional shape of the guard is arcuate, the contact surface with a solid material such as a concrete ridge is small and it is preferable from the standpoint of avoiding wear or damage. However, other shapes can be applied to the present invention as long as they can protect the holder.

[Effect of device]

 By installing a guard for protecting the holder at the end of the drum rotor of the control work machine, the impact during operation of the work machine is mitigated, fatigue is remarkably reduced, and mental tension is alleviated. In addition, the sudden failure of the drum rotor can be prevented, the work on the side of the concrete ridge can be facilitated, and the service life of the drum rotor can be extended, so that the maintenance cost can be reduced.
