Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lateral moving mechanism between multiple super-deep tilling rotaries.

[0002]

2. Description of the Related Art Japanese Utility Model Application Laid-open No. Sho 60-77301 relates to a slide mechanism for a deep tiller for a long root crop such as a long root vegetable. In this technique, the deeply cultivated part is arbitrarily moved in order to cope with different row widths depending on the root vegetables.

[0003]

In the above-mentioned slide mechanism, the main body of a heavy heavy ultra-deep tilling machine is configured to slide backward with respect to a horizontal main shaft approaching a lower portion of a mast frame. Therefore, there is a problem that the weight is applied as a cantilever force to the horizontal spindle. When the cantilever is moved laterally, a galling action is generated on the sliding portion to cause an obstacle, and furthermore, an impact force at the time of work is applied to the support frame as a bending action, causing an accident such as breakage.

[0004]

In order to solve the above-mentioned problem, a cross beam I and a cross beam II are laid horizontally in front and rear in parallel.
The drive case of the super deep rotary part of the pair is
II, and a support member is provided before and after the drive case, and the weight is attached to the front and rear cross beams I and II.
It is constructed so that it can be dispersed and supported between and can be moved laterally,
In addition, the present invention provides a laterally moving mechanism of the ultra-deeply-cultivated rotary, characterized in that the ultra-deeply-cultivated rotary parts are connected to each other by a hydraulic cylinder so as to be extendable and contractable to obtain a predetermined ridge width.

[0005]

When deeply cultivating a field with the ultra-deeply cultivated rotary according to the present invention, a set of ultra-deeply cultivated rotary parts are moved relative to each other in order to adjust to a required ridge width depending on a crop. The super-deeply cultivated rotary portion, which is arranged between the front and rear cross beams and supported by its weight, can easily move laterally when the mounting portion by one of the supporting members is released and the hydraulic cylinder is operated. After that, the support material is fixed. Further, if necessary, by releasing the mounting portion of the other portion and operating the hydraulic cylinder, a predetermined furrow width can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration will be described with reference to the drawings embodying the present invention. FIG. 1 is a side view of the present invention, FIG. 2 is a front view, and FIG. 3 is a plan view. 1 is a mast frame having a top bracket 15 at the top and lower pins 16 at both lower parts. At the lower end of the mast frame 1 is a cross beam I
4 and the cross beam II5 is arranged in parallel with the rear part, and both sides thereof are connected to the side frame 22, and are formed in a rectangular shape in plan view. An input transmission 2 is arranged at the center of the cross beam II5, and a transmission shaft 3 having a hexagonal cross section protrudes from both sides thereof, and is supported by left and right side frames 22. Reference numeral 14 denotes a mast cylinder that connects the top bracket 15 and the rear cross beam II5. Reference numeral 6 denotes a drive case, which is configured such that a transmission shaft 3 penetrates through the upper portion thereof, and power is transmitted, so that the drive shaft 3 is slidable in the lateral direction. The drive case 6 has a front portion attached to the cross beam I4 by the support member I12, and a rear portion attached to the rear cross beam II5 by the support member II13. FIG. 4 shows the drive case 6
It is a side view which shows the attachment state of. The support member 12 has a U-shaped clasp 19 at the front end and a cross beam I4 having a square cross section.
And is fastened together with the bracket 20 by a vault. The upper surface of the holding member 19 abuts against the upper surface of the cross beam I4 to support the weight of the deeply cultivated rotary portion. The support member II13 provided at the rear of the drive case 6 has a flat backing plate 18, and abuts against the upper surface of the receiving plate 21 forming the upper surface of the cross beam II5 to support the rear weight of the drive case 6. . The backing plate 18 and the receiving plate 21 have a number of fixing holes, and are fastened at arbitrary positions by volute. FIG. 5 shows power transmission from the transmission shaft 3 to the inside of the drive case 6. Although not shown, it is attached to the rear of the tractor by a three-point link, is transmitted from the PTO shaft to the input mission 2, and the transmission shaft 3 is rotated. When the transmission shaft 3 rotates, the intermediate shaft 11 is rotated by the sprocket and the chain, and then the rotation shaft 9 rotates to rotate the disk 8.
The excavating blades 10 arranged at the tip of the disk 8 form a predetermined deep plow. Next, the operation of moving the ultra-deep rotary part in the lateral direction will be described. First, the holding money 19 of one support member 1
Loosen the vault to make it slidable. Next, the fastening vault between the backing plate 18 and the receiving plate 21 is removed. Then, a stopper is attached at a position of a predetermined width. Here, when the hydraulic cylinder 7 expands and contracts, it moves. Here, if the front and rear vaults are fastened and the other side is similarly moved laterally, the desired deep tillage ridge width is obtained.

[0007]

[Effect] With the above structure, the laterally moving operation of a large and heavy super-deep rotary can be very easily and accurately performed.
