Abstract

PURPOSE:To prevent increase in respective tine holder weights by equipping reinforcing rings capable of connecting the tine holders for reinforcement at the open side of the plural U-shaped tine holders radially projecting from a tillage tine shaft. CONSTITUTION:Plural tine holders 2 and 2 radially projecting from a tillage tine shaft 1 are reinforced using reinforcing rings 3 at both side parts along the tillage tine shaft and the respective tine holders 2 and 2 are interconnected by the reinforcing rings. The load of the tillage shaft can be supported without increase in the respective tine holder weights because of strengthening in the direction of rotation of the tillage shaft by the respective tine holders and reinforcing rings.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a tilling claw support device for a tilling claw shaft.

PRIOR ART AND PROBLEMS TO BE SOLVED BY THE INVENTION A claw holder for attaching a tilling claw to a tilling claw shaft is formed, for example, in the shape of an open mouth on one side perpendicular to the tilling claw shaft, and is mounted radially from the tilling claw shaft. In a claw holder that protrudes from the top, the claw holder receives a large load such as an impact load due to the tilling action of the tiller claws, so it is necessary to make it strong, especially in the direction of rotation of the tiller claws. However, simply making the claw holder thicker may result in increased weight and cost.

Means for Solving the Problems This invention provides a plurality of claw holders (2) (2) (2) (2) projecting radially from a tilling claw shaft (1), which are perpendicular to the tilling claw shaft (1). In addition to forming a mouth shape with one side open, the open sides of these claw holders (2) (2) (2) (2) are reinforced by connecting the claw holders +2) (2) (2). A tilling claw support device for a tilling claw shaft is provided with a reinforcing ring (3).

Functions and effects of the invention A plurality of claw holders protruding radially from the tilling claw @ (1) +2) (2) (2) (2) has reinforcing rings (3) on both sides along the tilling claw axis (1). ) and a reinforcing ring (3) between each claw holder (2) (2) +2) (2).
), the strength is increased by the combined forces of the respective claw holders (2) (2) (2) and the reinforcing ring (3), especially in the direction of rotation of the tilling claws.

Due to this effect, there is no need to increase the wall thickness of each claw holder as in the above-mentioned problem, and therefore, it is difficult to increase the weight or increase the cost.

Embodiment When rotating, the tilling claw shaft 11) in the left and right direction is supported at the lower end of the shaft case (5) in which the vertical transmission shaft is installed, and the tilling claw shaft 11) is connected from the transmission shaft in the shaft case (5). Cultivating claw shaft (1
) is provided with a transmission case (6) containing a transmission mechanism for transmitting power.

The transmission case (6) is located close to the tiller shaft (1).

A plurality of U-shaped claw holders (2) 12) with open sides of the transmission case (6) perpendicular to the tilling claw shaft are provided, and left and right claw holders (2) 12) are provided near the tips of these claw holders (2) (2). The bolt hole (7) (7) in the direction has the claw holder (
2) Tilling claw (8) that fits into the U-shaped part of (2) 1B)
are respectively fastened with bolts (9) (91) and nuts (II and III).

The claw holder (2) (2) The tilling claw shaft (1) on the open side
) and the bolt holes (7) (7), there is provided a reinforcing ring (3) that connects and reinforces these claw holders (2) (12).

In addition, (Ill is an extended tilling claw shaft, and Tapping is an extended tilling claw shaft (I
This is a fixing pin that fixes n to the tiller claw shaft (1).

Next, the effect will be explained. The transmission mechanism inside the transmission case (6) receives power from the transmission shaft inside the shaft case (5).

Power is transmitted to the tilling claws (8) (8) via the tilling claw shaft (1) and the claw holders (2) (2) (2).

The load on the tilling claws (8) due to tilling is supported by the side parts of the claw holder (2) and the reinforcing ring (3) via both sides of the claw holder (2) in the rotating direction, and the reinforcing ring (3) ) reinforce each other against the load of each claw holder 12) (2) by the resultant force.

In addition, the outer circumferential surface of the reinforcing ring (3) easily prevents grass, straw, etc. from wrapping around the base of the claw holder (12) (2) that occurs during tilling.

Claims (1)

[Claims] A plurality of claw holders (2) (2) protruding radially from the tilling claw shaft (1) are formed into a U-shape with one side open perpendicular to the tilling claw shaft (1), and these claw holders (2)
) A tilling claw support device for a tilling claw shaft, which is provided with a reinforcing ring (3) for connecting and reinforcing the claw holders (2) (2) on the open side of (2).
