Abstract

PURPOSE:To prevent the damage to human body, etc., with a side supporting member having a bearing supporting an end of a tilling edge shaft, by providing both front and rear sides of the supporting member with protrusion edges protruding inward in right and left directions. CONSTITUTION:A right side wall of a central transmission case 6 is provided with a tubular supporting member 11 having a flange 7 at the right side end. The flange 7 of the supporting member 11 is connected with a suspended side- supporting member 3 having protrusions 4 protruding inward in right and left directions at both front and rear ends. Right and left bearing 2 are attached to the lower end of the side-supporting member 3 and a tilling edge shaft 1 planted with a proper number of tilling edges 12... is supported by the bearings 2 and 9. Since both front and rear protrusion edges 4, 4 of the side supporting member 3 are protruded inward, the outer side wall of the supporting member 3 is formed into a flat form free from danger even if contacting with human body.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a rotary tiller, which is used by being attached to a tractor or tiller.

Prior Art and Problems to be Solved by the Invention One end of the tiller blade shaft is attached to the lower end of a side transmission case containing a transmission mechanism for transmitting power to the tiller blade shaft, and the other end is attached to the side. In a rotary cultivating device in which the side supports are each supported by shaft bearings at the lower end, the side supports, which are usually made of plate material, have left and right side supports at both the front and rear ends in order to provide the necessary strength. Protruding edges that respectively protrude outward are provided,
Since this side support is located at the outermost side of the rotary tilling device, it is likely to come into contact with a person's body, etc., and therefore, the projecting edges projecting outward may pose a danger.

Means for Solving the Problems This invention provides a side support (3) having a shaft support (2) supporting one side end of a tilling blade shaft (11) in the left and right direction at its lower end.
The rotary tillage bag has a structure in which protruding edges (41(4)) are provided at both front and rear ends of the rotary plowing bag, each protruding inward in the left-right direction.

The active side support (3) of the invention supports the shaft support (2) by maintaining the necessary strength at the front and rear projecting edges (41 (41), and supports the shaft support (2).
) supports one end of the tiller blade shaft (1).

Effects of the Invention As in the above-mentioned problem, the front and rear projecting edges (41+4) of the side support member (3) are not made to project outward, but are made to project inward. The outer surface of the support body (3) is formed flat, so that even if a human body or the like comes into contact with the side support body (3), it is unlikely to cause any danger.

Embodiment In the example shown in Figure 1, a central transmission case (6) is provided in which an input shaft (5) for transmitting power from the tractor side projects forward and a transmission mechanism is installed inside. A pipe-shaped support (8) having a flange (7) at its left end and housing a transmission shaft therein is provided on the wall, and this flange (7) has a shaft bearing (9) at its lower end. A side transmission case (11) containing a transmission mechanism for transmitting power to the transmission shaft is connected thereto.

Further, a pipe-shaped support (1υ) having a flange (7) at the right end is provided on the right side wall of the central transmission case (6), and the flange (7) of this support (11) has a There are protruding edges (4
) (A side support (3) hanging down with ) and the shaft bearing part (9)
Toni.

A tilling blade shaft (1) on which an appropriate number of tilling blades 02102) are installed is supported.

In addition, (13 is a bearing fitted to the bearing body (2), 04 is a bolt that fastens the bearing body (2) to the side support body (3), (
19 is a prevention plate that prevents mud from entering the bearing, C1[9
is a tilling cover that covers the top of the tilling blade (Iδ (lδ...),
+177 is a link mast connected to the upper link on the tractor side, (111 is a coupling tool connected to the lower link on the tractor side.

Next, the effect will be explained. The input shaft (5) that is transmitted from the tractor side is connected to a transmission mechanism in the central transmission case (6),
The power is transmitted to the tiller blade shaft (1) via the transmission shaft in the support body (8) and the transmission mechanism in the side transmission case Tll.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; FIG. 1 is a rear view, FIG. 2 is a side view, and FIG. 3 is a partial side sectional view. In the figure, code (1) is the tiller blade shaft, (2) is the shaft support, and (3)
(4) indicates the side support and the protruding edge.

Claims (1)

[Claims] At both the front and rear ends of the side support (3), which has a shaft support (2) supporting one side end of the tilling blade shaft (1) in the left and right directions at the lower end, Projecting protruding edges (4
