Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a center drive type rotary device in which rotary shafts are protruded on both right and left sides of a transmission case driven from a gear case.

[0002]

2. Description of the Related Art Conventionally, a center drive type rotary device is constructed by welding a bracket to a mounting cylinder which is fitted and fixed to a rotary shaft and extended, and a rotary claw is attached to the bracket by bolting. I have.

[0003]

In some cases, the walking type management machine performs an operation of scraping the left and right soil to the center. This is performed, for example, during maintenance work of a tea plantation, when soil is placed on crawlers and tire marks after a work vehicle has passed through to maintain a work road surface. However, in the conventional center drive type rotary device, since the rotary claw is mounted via the bracket, the rotation diameter of the rotary claw becomes large by the length of the bracket, and the lower branch of the tea tree may be damaged. there were. In view of the above, it is an object of the present invention to provide a rotary padding device for a walking-type management machine, which surely scrapes left and right soil to the center to maintain a work road surface and does not damage surrounding trees.

[0004]

SUMMARY OF THE INVENTION In a center drive type rotary device in which rotary shafts 3, 3 are protruded on both right and left sides of a transmission case 2 driven from a gear case 1, a fitting fit is fixed to the rotary shafts 3, 3. The mounting cylinders 30, 30 are inclined obliquely downward toward the left and right sides, and a plurality of rotary claws 4, 4 forming a guide surface 31 facing inward, and notches 6, 6 provided at the base thereof. 30 and 30 were directly welded and attached, and the arrangement was attached in a helical manner with the phases sequentially changed.

[0005]

In the rotator of the present invention, the notch 6 provided at the base of the rotary claw 4 is welded to the mounting cylinder 30 of the rotary shaft 3, so that the bracket as in the prior art is used. The rotary claw 4 can be directly attached to the mounting cylinder 30 of the rotary shaft 3 without having the rotary shaft 3 to reduce the rotation diameter, and work can be performed without damaging the lower branches of the surrounding trees. In addition, the mounting cylinders 30, 30 are inclined obliquely downward toward the left and right outer sides, and a plurality of rotary claws 4, 4 forming a guide surface 31 are arranged in a helical shape with sequentially different phases. Therefore, the left and right soil can be smoothly guided toward the center while the space S is secured below the central transmission case 2.
Therefore, compared to a so-called residual tillage treatment device in which the mounting cylinders 30, 30 are simply inclined obliquely toward the left and right outer sides and the entire tillage width including the lower part of the transmission case 2 is formed flat, the effect of putting the soil to the center is improved. It is extremely expensive.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. The walking type management machine having the mulch rotary device of the present invention is provided with a gear case 1 in the center of the body,
The power from the front engine 7 is transmitted to the traveling device 8 and the rotary device 5 below to perform traveling and earth work. The traveling device 8 is attached to the lower end of the traveling transmission case 9 extending downward and forward from the gear case 1, and the rotary device 5 is attached to the lower end of the rotary transmission case 2 extending downward and rearward from the gear case 1. The traveling device 8 and the rotary device 5 are disposed at the front and rear at the center of the body. A dirt cover 11 is attached to a mounting frame 10 extending rearward from the gear case 1 so as to cover the upper part of the rotary device 5 and prevent the dirt from flying upwards. Reference numeral 12 denotes a resistance rod for adjusting the soiling depth of the rotary device 5, and extends downward from the rear end of the mounting frame 10.

A handlebar 13 is provided above the gear case 1 so as to extend rearward and upward, so that an operator who walks rearward of the fuselage can perform a steering operation with the handlebar 13. Reference numerals 14 and 14 denote grips attached to the rear end of the handlebar 13, and a gear case 1 near the grips 14 and 14.
Clutch lever 15, intermittent power to stand 1, stand 1
6 is provided with a stand lever 17 for rotating the rotating shaft 6, a change lever 18 for switching the traveling speed, a handle rotating lever 19 for adjusting the vertical height of the handle rod 13, and a rotary clutch lever 32 for interrupting power to the rotary device 5. ,
It is convenient for steering operation with the handlebar 13 held. The handle rod 13 is composed of two pipe rods extending radially in plan view with the gear case 1 as a center, and the right and left pipe rods are connected and reinforced by a connecting rod 20 at the front and rear intermediate portions. Reference numeral 21 denotes a safety switch disposed at the center of the connecting rod 20, and when the switch 21 is pressed, the driving of the engine 7 is stopped.

A mounting base 22 for mounting the engine 7 is formed in front of the gear case 1, and the engine 7 mounted on the mounting base 22 and the gear case 1 are connected by a belt to enable power transmission. Reference numeral 23 denotes a transmission cover that covers a transmission portion of the belt, and reference numeral 24 denotes an engine cover that covers an upper portion of the engine 7. A rotary transmission lever 25 for operating the rotational speed of the rotary device 5 is provided on one of the left and right sides of the gear case 1, and a traveling transmission lever 26 for operating the traveling speed and the forward / reverse direction is provided on the other side. Reference numeral 27 denotes a bumper frame attached to the front end of the aircraft, which protects the aircraft from obstacles that collide from the front of the aircraft.

In the rotary device 5, mounting cylinders 30, 30 each having a plurality of rotary claws 4, 4 mounted on rotary shafts 3, 3 projecting from the rotary transmission case 2 on both left and right sides, are fitted and fastened. The mounting cylinders 30, 30 are inclined obliquely toward the left and right outside and downward, so as to constitute a so-called center drive type rotary device. The rotary claw 4 of the rotary device 5 is provided with a notch 6 having a diameter substantially the same as the mounting cylinder 30 of the rotary shaft 3 at the base, and the mounting cylinder 30 is directly welded to the notch 6 and mounted. The rotation diameter is made smaller than that mounted through the space, and a space S is provided below the central rotary transmission case 2.
Is formed. The rotary pawl 4 is mounted with the guide surface 31 facing the inside of the machine body, and is arranged in a helical manner with the phases being sequentially changed.

In order to carry out the burying work in the tea garden using the walking-type management machine having the above-described configuration, the traveling device 8 provided below the body is required.
While pulling the fuselage with, the work is performed by scraping the soil with the rotary device 5 at the rear. Since the rotary device 5 is configured such that the rotary claw 4 is directly welded to the mounting cylinder 30 of the rotary shaft 3 to reduce the rotation diameter, a sufficient space between the surrounding tea tree and the rotary device 5 is ensured to damage the trees. Work can be done without any Further, the left and right soil can be smoothly guided toward the center by the space S formed below the central transmission case 2 and the rotary claw 4 having the guide surface 31 attached to the inside of the body. Further, since the rotary pawls 4, 4 are arranged in a helical shape with different phases sequentially, the effect of burying the soil at the center is further improved, and the rotary pawls 4, 4 operate continuously. Less vibration.
It should be noted that, in the claims, numbers are provided for convenience in comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by this entry.
