Description

[Detailed Description of the Invention] The present invention relates to a mulching device for a rotary tiller, which is capable of carrying out mulching work at the same time as rotary tilling work.

When a field is tilled with a rotary tiller, depending on the tilling method, the soil may be locally reduced and depressions may be formed, and these depressions are a problem in paddy fields.

Therefore, conventionally, after rotary work, the depressed areas were backfilled with soil, but this relied on manual work and was a runner-up in terms of work efficiency.

Therefore, it is conceivable to attach a mulch device to the rear of the rotary tiller, but it is desired that the structure of the attachment be simplified.

The present invention has been made in order to solve the above problem, and its feature is that flanges are provided at both ends of a horizontal member installed horizontally at the rear of the rotary body, and a In a rotary tilling device in which a gauge wheel is supported on a holding arm attached to the rotary tilling device, a pair of left and right mulching plates is arranged behind the rotary tilling part of the rotary tilling device, and the mulching plates are supported so as to be adjustable in angle around a vertical axis. The plate is removably held between the pair of flanges and aligned with each other.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.
In the figures, 1 is an input gear case, 2 is a transmission case, and 3 is a support arm, which constitutes a rotary body 4, which is attached to the rear of the tractor body via a three-point linkage mechanism 5 so as to be movable up and down. ing.

Reference numeral 6 denotes a pawl shaft rotatably supported at the lower end of the transmission case 2, and a rotary tilling section 8 is constructed by installing a large number of tilling pawls 7 on this pawl shaft.

Reference numeral 9 denotes a rotary cover that covers the rotary tilling section 8, and is separated from a front cover 10, a rear cover 11, and a side cover 12.

Reference numeral 13 denotes a gauge wheel support frame, which extends rearward from the support arm 3 of the rotary machine body 4, and is connected to the spiral rod 14.
It is more adjustable up and down.

The gauge wheel support frame 13 has a horizontal member 15 at its rear end, and holding arms 18 for holding the struts 17 of the gauge wheel 16 are removably flanged to both ends of the horizontal member 15 by bolts and nuts 19. There is.

Reference numeral 20 denotes a pair of left and right earth mooring plates arranged at the rear of the rotary tiller 8, which are configured in a roughly dogleg shape with a thousand sides;
It has vertical supports 21.

The support column 21 is vertically and rotatably inserted into the holding cylinder 22 and can be fixed with a set bolt 23, and a link 24 is attached to the upper end of the support column 21.

The holding cylinder 22 has a mounting plate 25 as shown in FIG.
are collinear with each other.

A turnbuckle 28 is interposed between the left and right links 24, and has a bundle 29.

In the above configuration, when carrying out mulching work at the same time as rotary work, loosen the set bolt 23, slide the support column 21 up and down within the holding tube 22 according to the plowing depth, and move the mulching plate 2.
After adjusting the height of 0 as appropriate, the set bolt 23 is tightened and fixed.

In addition, although the illustrated example shows the mulch plate 20 perpendicular to the direction of movement, the inclination angle of the mulch plate 20 can be adjusted depending on the purpose, such as when gathering soil to the center or to both sides. Yes, this adjustment is done using set bolt 23.
If you adjust the expansion and contraction of the turnbuckle 28 while loosening the
Since the support column 21 rotates within the holding cylinder 22 and the bulwark plate 20 is tilted, this can be done by adjusting the expansion and contraction of the turnbuckle 28.

Furthermore, since the upper shoring board 20, the link 24, and the turnbuckle 28 are the same as a parallel link mechanism in a plan view, it is also possible to orient each shoring board 20 in parallel in one direction.

Once the height and inclination angle of the mulch plate 20 have been adjusted, the rotary tiller is then lowered and towed by a tractor as shown in FIG.

Then, at the same time as the rotary tilling section 8 tills the soil, the topsoil can be gathered in a predetermined direction using the mulch plate 20, which is very convenient when puddling and mulching at the same time.

As described in detail in the embodiments above, in the present invention, a pair of left and right mulching plates is arranged behind the rotary tilling section, so that mulching work can be performed at the same time as rotary work, and work efficiency is significantly improved.

In addition, since the rotary plowing soil is collected, the traction resistance of the tractor is also relatively small.

Furthermore, the angle of the mulch plate can be adjusted around the vertical axis, and it is possible to bury the mulch in any direction as required.

In addition, in the present invention, the mounting plate of the shoring device is configured to be removably sandwiched and collinear between the flanges for mounting the gauge wheel, so the mounting structure is extremely simple.
