Abstract

(57) [Abstract] [Purpose] To improve the propulsive force of a disk wheel that also serves as a weeding machine in a walk-behind management machine that has a disk wheel that also serves as a weeder at the outer end of a rotary device for weeding. [Structure] Radial cuts a are formed at predetermined intervals in the circumferential direction on the outer periphery of the disc type wheel 4, and a disc rotation direction upper hand side portion 4a and a disc rotation direction lower hand side portion 4b of the cut a portions are formed. The slit 4a is bent in a triangular shape in the axial direction from the radial inner side to the outer peripheral portion, and the bent piece 4a 'on the upper side of the disc rotation direction is directed to the outside of the machine and the disc rotation direction. Bending piece 4 on the lower side
B'is bent toward the inside of the aircraft.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a walk-behind management machine for weeding and the like that is used for weeding on the side surface of a ridge, and more specifically, a rotary machine for weeding is attached to an axle protruding from a transmission case and its rotary The present invention relates to a walk-behind management machine in which disk wheels for weeding are attached to the outer end of the device.

[0002]

[Prior Art]

 A conventional disk wheel also used for weeding is provided with V-shaped cut grooves in a side view at predetermined intervals in the outer peripheral portion thereof, and the weeding work is performed in the cut grooves.

[0003]

[Problems to be solved by the device]

 When the cultivator dives deeply, the propulsive force is not exerted, and the aircraft is more likely to sink on the spot. An object of the present invention is to suppress the sinking of the airframe by devising the structure of a disk wheel that also serves as weeding.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the present invention for achieving the above object is to make radial cuts at predetermined intervals in the circumferential direction on the outer periphery of a disc type wheel, and to make disc cuts in the disc rotation direction on the upper side and the disc rotation direction. The lower part is bent in a triangular shape in the axial direction from the radially inner side of the cut to the outer periphery, and the bent piece of the upper part of the disc rotation direction is directed toward the outside of the machine and the disc. The bending piece on the lower side in the direction of rotation is bent toward the inside of the aircraft.

[0005]

[Action]

 As shown in Fig. 1, with the rotation of the disc-type wheel 4 which also functions as weeding, the bending piece 4a 'on the upper side in the disc rotation direction bites into the side of the ridge and exerts propulsive force to scrape off the weeds and rotate the disc. The bent piece 4b ′ on the lower side in the direction scrapes the scraped soil toward the inside of the aircraft.

[0006]

[Effect of the device]

 As a result of the above configuration, it is possible to perform good weeding work by suppressing the sinking of the aircraft during weeding work.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 3, a transmission case 1 is connected below a vertical engine E projecting an output shaft (not shown) downward, and a weeding rotary device 3 is attached to the axle 2 projecting from the transmission case 1. In addition, the disk type wheel 4 also used for weeding is attached to the outer end of the rotary device 3, and the support post 7 of the steering handle 6 is attached across the transmission case 1 and the rotary cover 5, and the steering wheel 6 is operated. A hitch 9 for mounting the resistance rod 8 is provided on the support post 7 of the handle to configure a walk-type control machine for weeding in the middle to remove weeds between the ridges. As shown in FIG. 2, in the rotary device 3, a hexagonal claw shaft 3A having a plurality of processing claws 3C on the outer periphery is externally fitted and fixed to a hexagonal axle 2 protruding from the transmission case 1, and the claw shaft 3A The boss portion 4A of the disk wheel 4 also used for weeding is externally fitted and fixed to the hexagonal shaft portion 3B fixed to the outer end portion. As shown in FIG. 1, the disc-type wheel 4 also used for weeding has radial cuts a on its outer peripheral portion at predetermined intervals in the circumferential direction. 4a and the disc rotation direction lower side portion 4b are bent in a triangular shape in the axial direction from the radial inner side of the cut a to the outer peripheral portion, and the bending piece 4a 'of the disc rotation direction upper side portion is formed. The bent piece 4b 'on the outer side of the machine body and on the lower side in the disc rotation direction is bent toward the inner side of the machine body.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the invention is not limited to the configurations of the accompanying drawings by the entry.
