JPH1014316A - Apparatus for erasing wheel track of tractor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an apparatus for erasing wheel track of a tractor, capable of simplifying the structure and smoothly and favorably tilling over whole width of a rotary without largely leaving wheel track by disposing an earthing up body for reburying wheel grooves in a space part formed between rear wheels and a tiller. SOLUTION: In a tractor installing a tiller 1 in the rear of a traveling machine body 2 having rear wheels 2K, an earthing up body 6 for reburying wheel grooves M formed on the ground by rear wheels 2K is disposing in a space part formed between right and left rear wheels 2K and the tiller 1. Furthermore, the earthing up body 6 is preferably detachably attached to a lateral frame 12 rotatably supporting a rotary 3 of the tiller 1 so as to enable vertical control.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for eliminating ruts of a tractor having a tilling device.

[0002]

2. Description of the Related Art Conventionally, a tractor is mounted on a rear part of a traveling body having a front wheel and a rear wheel through a lifting link via a lifting link, and a rotary cultivator is rotated as the body travels to perform tilling work. Is configured.

[0003]

Since this tractor has a large weight, the rear wheel formed of wide tires forms a large and deep groove on the ground after traveling, especially in a soft field. In this case, when the rotary tilling (shallow cultivation) is performed by the tilling device at a depth smaller than the depth of the rutted groove, the rutted groove cannot be completely filled with the cultivated soil even if the rotary tillies the ground. In this method, there is a problem that a cultivated soil surface is formed while leaving a concave rut trace in a streak shape.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the tractor rudder extinguishing device of the present invention includes a rear wheel 2k,
In a tractor in which the tillage device 1 is mounted on the rear part of the traveling body 2 having 2k, the rear wheels 2k, 2k are provided in a space formed between the left and right rear wheels 2k, 2k and the tillage device 1.
Has a burrow 6 for backfilling the rutted groove M formed on the ground surface. Further, the present invention is characterized in that the earthen body 6 is attached to the horizontal frames 12 and 13 which rotatably support the rotary 3 of the tillage device 1 so as to be attachable / detachable and vertically adjustable.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a tillage device, which is a front wheel and a rear wheel 2k.
At the rear of the traveling body 2, such as a tractor, having a hitch portion, it is detachably mounted.
The tilling apparatus 1 has a body frame 1a having a structure similar to that of a conventional apparatus. That is, the body frame 1a
Is a top mast 1 mounted on the lifting link mechanism 2a.
0 is fixed to a transmission case 11 input from the traveling machine body 2 and horizontal frames 12, 13 on the upper side of the hollow pipe project from both sides of the transmission case 11; A chain transmission case 14 for supporting the rotary shaft 3b of the rotary 3 having the rotary shaft 3a and a support frame 15 are provided, and a rotary cover 4 for covering an upper part of the rotation trajectory of the rotary 3 is fixed by the transmission case 14 and the support frame 15. It has a rigid structure.

The rotary 3 is rotationally transmitted from the transmission housing 11 via a transmission shaft (not shown) pivotally supported in the horizontal frame 12 and a chain transmission mechanism housed in the transmission case 14. A rear cover 4a is rotatably supported by the rear end of the rotary cover 4 in a suspended state.
It adjusts to a predetermined depth while covering the soil to be plowed with.

[0007] A trace extinguishing device 5 according to the present invention is disposed in a space formed behind the left and right rear wheels 2k, 2k and in front of the rotary 3 of the tilling device 1, whereby the body 2 travels. In this case, the rear wheels 2k, 2k are configured to bury the rutted grooves (rut marks) M formed on the ground surface to erase the marks. The trace erasing device 5 according to this embodiment is shown in FIGS.
As shown in the figure, a support rod 60 for rotatably supporting the clay body 6.
And a support 7 which supports the support rod 60 so as to be vertically adjustable by an adjustment screw 71 in a state of being inserted into the support cylinder 70. The burrow body 6 is formed of a disk plate having protruding teeth on the outer periphery, and as shown in FIG. 3B, and is pivotally supported by the bifurcated support arm 61 of the support rod 60 so that the front is in an expanded posture in plan view as shown in FIG. 3B.

[0008] With this configuration, the soil burying body 6 can cut down the soil that has risen on both sides of the rutted groove M while rotating while contacting the ground with the running of the fuselage 2. Since the soil can be smoothly buried in the rutted groove M as if using a shovel, the rutted groove M (rut mark) formed by the wide rear wheel 2k can be efficiently erased.

As a result, when the rotary 3 located on the rear side plows the ground, the entire tillage width is plowed evenly without leaving a part of the rutted trace in the rutted trace unlike the conventional device. Is what you can do. In addition, the dormitory 6 is a support 7
By operating the adjusting screw 71, the amount of vertical intrusion can be appropriately selected in accordance with the depth of the rut groove H and the tillage depth h (FIG. 2), and the height can be raised to a height not in contact with the ground surface. There are advantages such as being able to.

The support 7 is provided with a mounting portion 7 on the base side.
3 is joined to the outer periphery of the horizontal frames 12 and 13 so as to be held by the holder which can be divided into two.
2 and 13 are removably attached to the tilling apparatus 1 also as an attachment frame. As described above, the trace extinguishing device 5 has a simple structure on the side of the tilling device 1 and is attached and supported in a state of high rigidity, so that it can be moved up and down integrally with the up and down movement of the tilling device 1 to support the tilling operation. Can be performed smoothly without any problem. When the tilling device 1 is detached from the traveling machine body 2, the soil wreck 6 can be grounded to the ground and used as a stand, and the tilling device 1 can be grounded to the ground in a stable posture. is there.

With the above-described structure, the trace extinguishing device 5 according to the present invention includes the rear portions of the rear wheels 2k and 2k and the tilling device 1
And the rutted groove M is grounded by using the space formed between them and can be satisfactorily buried and erased along with the travel of the aircraft.

[0012]

According to the present invention, during the tilling operation, the rear wheel fills the rutted groove formed on the surface of the ground with the soil burying body in front of the tilling device, and burying the soil that has risen on both sides of the rutted groove into the rutted groove. Since the rotary plows the rutted groove, the plow can be tilled smoothly and smoothly over the entire width of the rotary without leaving a large rutted mark. Further, the earthen body can be supported with high rigidity and with easy attachment / detachment by having a simple structure by being attached to the horizontal frame of the tillage device.
