Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to agricultural machinery, and particularly to a ridge-making machine that tills a field and heaps up the soil to form ridges.

(Prior art) Taking an example of an external ridge forming method using a conventional ridge making machine, the field is first tilled with a tiller wheel, the tilled soil is thrown up to the side by a flip-up blade to form a ridge, and then the ridges are heaped up. A pair of left and right soil pressing plates that are open at the top are opened and closed in swing motion to compress and compact the cultivated soil to form a ridge with an inclined slope.

By the way, in the ridge forming method using the conventional ridge forming machine,
There are the following problems.

That is, in this ridge making machine, in order to flip up the tilled soil to the sides of the furrow and heave up the ridges, the tilling wheel is rotated in the opposite direction to normal, and the flip-up blade scrapes out the cultivated soil.
The upper part of the ditch has more soil deposited, but the lower part has less soil.

For this reason, by opening and closing a pair of left and right soil pressing plates that open upward, the soil in the upper part of the ridge is compressed and compacted strongly by the action of the soil pressing plate, but the soil in the lower part of the ridge is compacted. Because of the small amount of soil, there is insufficient pressing force and it is not possible to compact the soil sufficiently, which causes the problem that the lower part of the ridge becomes weak and easily causes soil collapse.

Therefore, in view of the above problems, the present invention compresses the upper part of the ridge, and separately compresses the lower part of the ridge independently from this,
To provide a ridge making machine capable of firmly compacting the entire ridge to prevent soil collapse.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a rotatably driven tilling wheel and a rocking motion behind the tilling wheel that opens and closes to mound up the cultivated soil and press it against the ridges. In a device having left and right earth pressing plates for forming, the earth pressing plate is composed of a first earth pressing plate that mainly presses the upper part of the ridge, and a second earth pressing plate that mainly presses the lower part of the ridge. (Operation) To form a ridge, first, a tilling wheel with flip-up blades attached to a predetermined width is rotatably driven to till the field, and then the field is cut approximately vertically downward to a predetermined width. Form the tillage surface. Then, the plowed and dug up soil is flipped up with a flip-up blade to heave up the ridges. Next, when the first and second earth pressing plates located at the rear are opened and closed, the first earth pressing plate hits the slope of the ridge mainly from the upper part of the ridge to push and compact the cultivated soil, and further Since the second soil pressing plate compacts the cultivated soil mainly in the lower part of the ridge, the lower part of the ridge with less cultivated soil can be sufficiently compressed and compacted, and a strong slope of the ridge is formed as a whole.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4. This ridge forming machine 1 is of an external mounting type, has an engine 1a mounted on a frame F as a driving source, is provided with a handle 1b that the operator operates while walking, and is further provided with a pair of running wheels that are rotationally driven by the engine 1a. Wheels 2 are installed. A tilling wheel 3 is provided at the bottom of the frame F. This device has a plurality of flip-up blades 5 attached to a rotating shaft extending left and right from a reducer box 4, and is driven to rotate in the opposite direction so as to flip the cultivated soil forward by transmitting the rotational force of the engine la. be done. Further, the frame F at the rear of the tilling wheel 3 is provided with soil pressing plates 6 on the left and right, and the soil pressing plates 6 include a first soil pressing plate 6a that mainly presses the upper part of the ridge and a lower part of the ridge. and a second soil pressing plate 6b that mainly presses the engine 1a.
It is connected to an operating rod that is connected to the output shaft of the holder, and provides swinging movement to open and close it.

Next, regarding the first and second soil pressing plates 6a and 6b, the second to third
This will be explained using figures. First, the first earth pressing plate 6a consists of a front part and a side part, and the side part is arranged in an upward-opening shape, and the lower part is a lower part extending left and right to the lower part of the vertical machine frame 7 attached to the frame. The horizontal machine frame 8 is rotatably mounted on both sides of the frame 8 as rotation fulcrums 9. Note that a front plate 10 that covers the front surface is fixed to the compressor frame 7 in front of the first earth pressing plate 6a.

Further, a second earth pressing plate 6b is provided behind the first earth pressing plate 6a, and this one has its side portions opened upward, and the upper part of the first earth pressing plate 6a in front is rotatably mounted as a rotation fulcrum 11.

Operating rods 12 and 13 are rotatably connected to the upper inner side of the first earth pressing plate 6a and the inner lower side of the second earth pressing plate 6b, respectively. 13 is 2
It is connected to a swinging arm 14 which is a book arm connected in a substantially T-shape. That is, the swinging arm 14 is rotatably attached with the connection point of the arm being pivoted on both sides of the upper horizontal machine frame 15 that extends left and right to the upper part of the vertical machine frame 7, and both ends of this one arm are attached. The operating rods 12 and 13 are rotatably attached to each of the arms, and the other arm of the swing arm 14 is attached to the engine la.
Power is transmitted from the drive shaft 16, which is driven by the engine, through the crank attachment 17, crank arm 18, and drive arm 19 to provide vertical movement.

Due to this vertical movement, the swinging arm 14 swings, and the operating rods 12 and 13 alternately advance and retreat in the lateral direction, and the first earth pushing plate 6a
and the second earth pressing plate 6b alternately open and close, and since the second earth pressing plate 6b uses the upper part of the first earth pressing plate 6a as a rotation fulcrum 11, the first earth pressing plate 6b When the upper part of the pushing plate 6a retreats, the lower part of the second pushing plate 6b moves outward.

In the ridge-making work using the ridge-making machine 1 configured as described above, first, as shown in FIG. is raised laterally into ridges by the action of the flip-up blade 5.

Next, the soil pressing plate 6 at the rear is opened and closed in a rocking motion to compact the cultivated soil heaped up in the ridges. That is, as shown in FIG. 4(b), the first earth pressing plate 6a is oscillated to open and close using its lower part as a rotation fulcrum 9, and presses the entire ridge to form an inclined slope. At this time, since there is a lot of cultivated soil in the upper part of the ridge, the upper part is mainly compacted firmly, but there is less cultivated soil in the lower part and the pressing is insufficient. After that, Figure 4 (c
), the upper part of the second earth pressing plate 6b is connected to the rotation fulcrum 11.
When the upper part of the first soil pushing plate 6a retreats, the lower part moves forward, so that the lower part of the ridge is mainly pressed, and even if there is only a small amount of cultivated soil, it can be sufficiently compacted. As a result, the entire ridge is firmly compacted.

In addition, this allows the lower part of the ridge to dig into the inside of the ridge and widen the width of the ridge. It is formed of an outer cylinder 8a and an inner cylinder 8b, which are nested to be expandable and contractible.
By making the length adjustable with the set screw 20,
Adjustable. In addition, as another embodiment, as shown in FIG. 2.3, the operating rod 13 of the second earth pushing plate 6b
A plurality of mounting holes 21 may be bored along the arm to make the mounting position on one side of the swinging arm 14 variable, thereby adjusting the amount of push-out of the second soil pushing plate 6b.

Note that the ridge making machine of the present invention has a first soil pressing plate 6a that mainly presses the upper part of the ridge, and a second earth pressing plate 6a that mainly presses the lower part of the ridge.
The embodiments are not limited to those described above. That is, in the embodiment shown in FIG. 5, the lower part of the first earth pushing plate 6a is rotatably mounted on the lower horizontal machine frame 22 at the rotary fulcrum 23, and the operating rod 24 is rotatably connected to the upper part. On the other hand, the upper part of the second earth pushing plate 6b is also rotatably mounted on the upper horizontal machine frame 25 at a rotation fulcrum 26, and the operating rod 27 is rotatably mounted on the lower part thereof. , each operating rod 6a.

6b is a piece 28 having two arms opened at approximately 90 degrees, which is rotatably attached to the frame with a pin joint, one arm 27a being used as an operating rod 24.27, and the other arm 28b being used as a crank arm. 29 to provide an opening/closing swing motion. Then, as shown in FIG. 6, the first earth pressing plate 6a presses mainly the upper part of the ridge, and the second earth pressing plate 6b presses mainly the lower part of the ridge. Further, as shown in FIG. 7, the second soil pressing plate 6b may be made small enough to correspond only to the lower part of the ridge, and configured to press the lower part of the ridge. In addition, the first soil pressing plate 6a
The second soil pressing plate 6b only needs to be attached so as to press mainly the upper and lower parts of the ridge separately, and its position in the front and rear does not matter.

Further, it is sufficient that at least the first and second earth pressing plates 6a and 6b are present, and a plurality of these may be provided, and the operating speeds of each may be made different.

In addition, although the above example shows an external piling type, an internal piling type in which tilled soil is raked inward is also applicable.
It is something that can be used.
