Description

[Detailed Description of the Invention] The present invention includes a rotary that is rotatably mounted over a rotary case and a support case, a cover body that covers the top and both sides of the rotary, and a cover body that covers the top and both sides of the rotary. This invention relates to a power cultivator having side force bars covering both sides and allowing the vertical position to be changed freely.

In this type of power tiller, the rotary body and the rotary side force bar are constructed separately, and as the bridge body is moved up and down to change the plowing depth, the lower edge of the side force bar and the bridge are There was a gap between the bodies, which caused soil to scatter laterally through the gap during tilling.

In view of the above points, the present invention uses a rational structure to prevent soil from scattering from the bottom of the side force bar during tilling, and effectively utilizes this structure to improve the structure of the bridge body and side force bar. The purpose is to strengthen the

To achieve the above-mentioned object, the present invention, in the above-mentioned tiller, pivots the front end of the bridge body for use in cultivating depth so as to be swingable up and down and fixed at the lower end rear part of each of the rotary case and the support case. supportingly connecting the body and the side force bar;
The side force bar is characterized in that the entire length or almost the entire length of the lower end edge of the side force bar is connected to the upper surface of the orange body.

In other words, in order to regulate the plowing depth, the lower edge of the side force bar is connected to the upper surface of the tree, which receives the weight of the rotary device on the ground and is constantly pressed down to the ground with a large force. Since there is no gap between the two and the gap between the habitat and the side force bar, it is possible to prevent the soil from scattering to the outside of both structures during tilling.

As a result, it is possible to prevent the scattered soil from covering uncultivated areas close to cultivated land and blurring the boundary between cultivated and uncultivated land, making it possible to carry out plowing work more efficiently without unexpectedly leaving uncultivated land. Became.

Moreover, since the rotary case and the support case, which are inherently constructed with high strength, are effectively utilized, and the bridge body is pivotally connected to the lower end rear portion of each of these cases, for example,
Compared to the case where it is attached to the front of both cases or to the pond member, the distance between the grounding position of the bridge body and the above-mentioned pivot position can be shortened, and bending deformation of the bridge body can be avoided, and the body and side forces can be reduced. Since the bridge body is connected to the bridge body, the side force bar not only reinforces the bridge body, but also sufficiently reinforces the side force bar with the box body to improve its shape retention and increase the strength of the bridge body and side force bar. Now you can.

Hereinafter, embodiments of the present invention will be described in detail with reference to illustrative drawings.

A rotary device 3 for plowing work is connected to the rear of a tractor 2 on which wheels 1 are mounted on an axis, and a transmission 4 at the rear of the tractor 1 is connected.
From there, the internal transmission mechanism (not shown) is connected to the rotary case 6 via the internal transmission mechanism (not shown) to the transmission frame 5.
The vehicle is configured to transmit power to drive the rotary device 3, and a riding type tiller is configured to cultivate the field as the vehicle travels.

The rotary device 3 has a rotary 8 mounted on a shaft over a rotary case 6 on one horizontal side and a support case 7 on the other side, and has a cover body 9 with rubber sag attached above and behind the rotary 8, and has a cover body 9 on both sides. The sides are covered with side force bars 10.10 to prevent soil etc. from scattering outward during tilling.

At the rear of both sides of the rotary 8, in order to support the rotary device 3 on the ground, a rotary body 12 is provided, which is pivotably connected to a bracket 11 connected to the rotary case 6 and the support case 7, respectively. The free end of the swinging arm 15, which is pivotally connected to the transmission frame 5 so as to swing by the rotation of the operating tool 14, and the free ends of both of the body members 12 and 12 are connected to a rod 16 and rods 17, 17, respectively. Interlocking and connecting via
2 and 12 are moved up and down relative to the rotary 8 to change and adjust the plowing depth.

Each of the side covers 10 and 10 also has the habitat 12,
The bracket 11.1 is coaxial with each of the 12 pivot axes.
1, and both side covers 1
Almost the entire length of the lower edge of 0.10 is placed on the upper surface of each body 12, 12 and connected integrally by welding in an inverted T-shape. 10
．． 10 is designed to change its vertical position.

Reference numeral 18 in the figure denotes an elongated hole drilled in the side force bar 10, which is shaped like an arc along the circumference of the side force bar 10 and centered on the swing axis of the side force bar 10. A bolt 19 is provided protruding from the main body 9, and the side force bar 10 is fixed to and released from the cover main body 9 with a nut 21 via a packing 20 for earthquake prevention.

For integrally connecting the side force bar 10 and the body 12,
The cover 10 is not limited to the T-shape, but may be connected in an L-shape with the cover 10 placed on one end of the upper surface of the orange body 12.
