Abstract

PROBLEM TO BE SOLVED: To provide a front gauge wheel eliminating an unplowed soil at its rotation and capable of being mounted in a good working property with a lengthwise balance, a rotating performance, etc., by installing the gauge wheel of a rotary plower in the outside direction of the rear wheel of a traveling vehicle and in the front direction of the plowing blade. SOLUTION: This front gauge wheel 2 of a rotary plower 1 freely liftably mounted at the rear end part of the machine of a traveling vehicle 5, is installed in the outside direction of the rear wheel 3 of the traveling vehicle 5 and in the front direction of a plowing blade 4. Further, it is preferable that, in order to prevent a plowed soil from splashing caused by the driving rotation of a plowing pipe 19, the upper direction of the rotating locus of a tip end of the plowing blade 4 is covered by a main cover 20 and it rear side is covered with a rear cover 29.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a front gauge wheel for a rotary tiller.

[0002]

2. Description of the Related Art The front gauge wheel of a conventional rotary tiller is provided in the same width as the rear wheel tread of a moving vehicle for traveling. Therefore, if you try to cultivate the soil surface with a rotary tiller,
The front position of the gauge wheel is stomped by the rear wheel of the moving vehicle, and it becomes uneven due to the hardness and softness of the soil, and the plowing depth at the time of plowing is not stable, or the gauge wheel and the rear wheel as shown in the figure as a conventional example. In order to prevent interference, the rotary tiller must be moved far away from the moving vehicle, and the amount of overhang increases, the amount of uncultivated land at the time of turning increases, the work efficiency decreases, and the turning radius increases, which makes driving operation difficult. It was hard to do.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to eliminate such drawbacks of the conventional device, and has taken the following technical means. That is, the gauge wheels 2 and 2 of the rotary cultivator 1 which are attached to the rear end portion of the vehicle body of the moving vehicle 5 so as to be lifted up and down are provided outside the rear wheels 3 and 3 of the moving vehicle, at the plowing blades 4, 4. . . The front gauge wheel of the rotary tiller, which is characterized by being installed in the front, is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The illustrated embodiment is one in which the present invention is folded into a front gauge wheel 2 portion of a rotary tiller 1, which will be described with reference to FIGS. 1, 2 and 3. The rotary tiller 1 pivotally supports the front end of the top link 7 on a hitch 6 in the center in the left-right direction fixedly provided above the rear end of the main body of the moving vehicle 5 which is an agricultural tractor, and pivots the front end of the mast 8 at the rear end of the top link 7. I support you. Further, the front ends of the lower links 10, 10 are pivotally supported on the lower left and right of the rear end of the mission case 9 of the tractor, and the rear ends of the lower links 10 are beams 12, 12 protruding laterally from the transmission case 11 at the center in the left-right direction. The lower link 1 is pivotally connected to the front ends of the support plates 13, 13 fixed to the
The lower ends of the left and right lift rods 14 and 14 are pivotally supported in the middle of 0 and 10, and the upper ends of the lift rods 14 and 14 are pivotally connected to the lift arms 15 and 15 to rotate the lift arms 15, thereby cultivating the rotary tiller. The tool 1 can be raised and lowered.

A mast 8 is pivotally supported on the central transmission case 11, and the middle part of the mast 8 and the support plates 13, 1 are supported.
Left and right reinforcing links 16, 16 are interposed between the three. Then, the side plate 1 is provided at the end of the beam 12 on the right side.
7 is fixed, a side transmission case 18 is fixed to the left beam 12 side end, and a cultivating pipe 19 is mounted between the side plate 17 and the lower end of the side transmission case 18, and the cultivating pipe 19 is cultivated. Blades 4, 4. . . Have been contacted.

Cultivating pipe 19 and cultivating blade 4, 4. . . The upper part is covered with the main cover 20, and mounting frames 23, 23 for mounting the stays 22, 22 of the gauge wheels 2, 2 are provided on the mounting plates 21, 21 provided at the left and right ends of the main cover 20, respectively. Between the mounting frame 23 and the stay 22, mounting adjustment holes 25, 25. . . There are a plurality of vertical tillers, and the one shown in the first example is a plowing blade 4 that can be adjusted vertically by hand.
Is adjusting the working depth.

Since the position of the gauge wheel 2 in the plane direction is located laterally downward of the rear wheel 3 of the moving vehicle 5, the rotation locus position of the plowing blade 4 for excavating the surface of the mud is forward as shown in FIG. The plowing work can be performed easily with less overhang. The drive of the tillage pipe 19 is transmitted from the PTO shaft 26 projecting to the rear end of the mission case 9 of the moving vehicle 5 to the input shaft 28 of the central transmission case 11 via the universal joint 27, and from the input shaft 28 via the bevel gear. The sprocket in the side transmission case 18 is driven by the transmission shaft (not shown) in the beam 12 on the left side, and the tilling pipe 19 is driven through the chain.

[0008] In order to prevent the tilling soil from scattering due to the drive rotation of the tilling pipe 19, the tilling blades 4, 4. . . . The upper part of the rotation path of the tip is covered with the main cover 20, and the rear part is covered with the rear cover 2.
Covered with 9. Reference numeral 30 denotes a swing shaft, which is the main cover 20.
The rear end of the rear cover 29 is a shaft that swings in the vertical and forward / backward directions with respect to the rear end. The conventional rotary tiller 1a in the conventional mobile agricultural machine 5a will be described with reference to FIG. 4. Since the gauge wheel 2a is provided in the vicinity of the tread of the rear wheel 3a, when the rotary tiller 1a is lifted,
Since it is necessary to separate the entire tiller rearward by the amount of preventing the rear wheel 3a and the gauge wheel 2a from interfering with each other, due to a large turning radius and lifting of the front wheel due to overhang of heavy objects,
Driving operation deteriorates.

In FIG. 5, the gauge wheel 2 is intended to be directly operated by the rotation of the electric motor 31 in the driver's seat 32 portion of the moving vehicle 5 by remote control. A switch 33 for rotating the electric motor 31 in the forward and reverse direction near the driver's seat 32
And the stay 22a of the gauge wheel 2 of the rotary tiller 1
The worm gear 34 and the worm wheel 35 are internally mounted in the mounting frame 23 part for attaching the worm gear 34, and the worm gear 34 is driven forward and backward by the electric motor 31, and the rack 36 part provided on the stay 22a is vertically adjusted to adjust the working depth. Control changes remotely.

The rotary tiller 1b shown in FIGS. 6 and 7 is
It is an offset type rotary and is attached to the moving vehicle 5 while being offset in the left-right direction. In order to balance the driving resistance of the tilling blade, the resistance claw 37 is attached to the beam 12 so as to be slidable left and right to adjust the left and right balance when moving forward while performing the plowing work. Reference numeral 39 is a mounting bracket, and 38 is an extending arm. Although not shown, when the tilling resistance is reversed by reverse tillage or the like,
In some cases, a balancing resistance claw 37 may be required on the right beam 12 side. Such an offset rotary tiller 1
By setting b, it is possible to cultivate up to near trees even in a place where tree branches project low in an orchard or the like, and the soil between trees can be softened to maintain the tree's momentum.

[0011]

According to the present invention, as described above, the gauge wheels 2 and 2 of the rotary tiller 1 mounted on the rear end of the vehicle body of the moving vehicle 5 so as to move up and down are arranged outside the rear wheels 3 and 3 of the moving vehicle. And plowing blades 4, 4. . . Since it is provided at the front, the rotary tiller 1 as a whole can be brought forward, and it is possible to attach the rotary cultivator 1 with good workability in terms of front-rear balance, turning ability, and the like.
