Description

[Detailed Description of the Invention] The present invention is directed to cutting and cultivating soil from field soil.
This invention relates to improvements to a same-row inversion tiller that turns soil into the same-row grooves that are formed in the traces of the soil by cutting the soil.

The work of tilling the soil in a field using a reversing tiller, such as a board plow, is a complicated method, and unlike rotary tillage, it requires considerable skill and is difficult to get used to. The most basic problem is that the tilled soil is turned over into the groove of the adjacent row, rather than into the groove formed by the tillage, so it takes much effort to open the plow. This may cause the soil to move, making it difficult to till the ridges, and if a multiple inversion tiller is used, the phases of the rows may shift at the point where they are inserted, making it difficult to till the headland. There is no such thing.

As a countermeasure to this problem, if the tilled soil is turned over at the rear of the reversing tillage machine, and the tilled soil is turned over into the grooves of the same row that are formed in the traces of the tilled soil, it will be possible to Although the various problems encountered have almost been solved, this is a historical problem with inverted tillage machines such as plows, and it is not an easy problem, and it has been carried over to the present day.

The present invention was made to solve this problem, and proposes a new means for inverting tilled soil into the same row of furrows formed by tilling the soil. With the goal.

In order to solve the above-mentioned problems, we conducted various research and experiments, and found that the means of the present invention divides the tilled soil into three parts in the direction of the rows and the width direction of the tilled soil. By sequentially inverting the three divided parts so that they overlap in multiple layers, we discovered that it was possible to invert the soil into the same row of grooves. It was completed based on this.

Therefore, in the present invention, a front inversion tillage body that directs tilling soil toward one side and inverts it, and a rear inversion tillage body that directs tillage soil toward the other side and guides it inversion. , those soils are arranged side by side when viewed from the front with their inversion directions facing each other and out of phase with each other, and the front inversion tillage body has blade plates on its leading edge side An arch-shaped blade part that leaves uncultivated soil in a semicylindrical shape is formed on the side of the front inversion tillage body that is closer to the reversal direction, and an end of the arch-shaped blade part on the reversal direction side is formed. , a means for configuring a same-row reversing tillage machine by forming a soil reversing plate for plowing and reversing the semicylindrical residual soil in a direction opposite to the reversing direction by extending in the opposite direction to the reversing direction is proposed. It is something.

Next, an example of implementation will be described in detail with reference to the drawings.

In Figs. 1 and 2, a is a front inversion tiller, which is composed of a blade plate part 1 on the leading edge side and a longitudinally long guide plate part 2 continuous to the rear of the blade plate part 1. The blade plate 1 is twisted so that the soil cut from uncultivated soil is turned over in one direction (in the direction of the thick arrow W in FIG. 1). The blade plate part 1 is formed so that its left and right width directions are long in the direction of reversal of the soil of the guide plate part 2, and protrudes in the above-mentioned reversal direction than the guide plate part 2 in plan view. As shown in FIG. 2, this part is formed in an arch-shaped blade part 10 whose lower surface side is cut into an arch shape, so that the blade part 1 cuts the soil from the uncultivated soil. When the plowing is carried out, uncultivated soil (g) is left behind which rises in a semicircular shape from the plowing surface, as shown by the diagonal lines in FIG. Further, the end portion of the blade portion 1 on the side of the reversal direction is curved so as to gradually move toward the opposite direction to the reversal direction as it faces rearward,
Its front edge 11a cuts the uncultivated soil g remaining in the semicylindrical shape, and the inner wall surface 11b cuts the uncultivated soil g.
The soil L ₁ is formed on a soil reversing plate 11 which is guided and reversed in a direction opposite to the soil reversing direction of the aforementioned guiding plate part 2. As a result, the front inverted tillage body a is formed in a shape as shown in the three-dimensional curve diagram shown with contour lines in FIG. It is supported on the machine frame by a beam 3 provided at the end portion.

b is a rear inverted tillage body, which has a blade plate part 40 on the leading edge side that cuts uncultivated soil and a guide plate part 4 continuous thereto;
It has the same form as a normal plow consisting of
The reversal direction of the soil L ₂ (Fig. 6) (the direction of the thick arrow Y in Fig. 1) is the reversal direction W of the guiding plate part 2 of the front reversal tillage body a mentioned above. and the reversal direction Y is the same as that of the guide plate part 2.
The front reversing tiller a is placed at a position closer to the rear on the side of the front reversing tiller a so that they face the reversing direction W of the reversing direction W, and is supported on the machine frame by the beam 42. As shown in Figure 2, it is supported on the machine frame in a state parallel to the front inversion tillage body a on the left and right, and thereby, in combination with the front inversion tillage body a, performs the same row inversion tillage work according to the present invention. It constitutes machine A.

Next, the soil reversal process performed by the same-row reversing tillage machine A constructed as described above will be explained.

As the front inversion tillage body a and the rear inversion tillage body b shown by the chain lines in Fig. 4 advance forward (upward in Fig. 4), the leading edge side of the front inversion tillage body a The soil L ₃ is cut by the blade part 1 of the fifth
As shown in the figure, a semi-cylindrical uncultivated soil g is left on the separated tillage surface, and it is continuous with the part that will become the soil L ₂ that will be plowed and reversed by the rear reversal tillage body b. It is scooped upwards and turned around so that it covers that part of the body. And this earth
The semicylindrical residual soil g left below L ₃ is removed from the soil inversion board 11 located behind the arched blade part 10 formed on the blade part 1 of the front inversion tillage body a. , Soil L ₁ is cut from the plowing surface, and is reversed below the aforementioned Soil L ₃ in the opposite direction to that of Soil L ₃ (Figure 6), and
The portion that becomes soil L ₂ , which is continuous with the soil L 3 described above, is cut into soil _{L 2 by} the rear inversion tillage body b, and is guided and inverted, resulting in soil consisting of the inverted residual soil g. The above-mentioned soil L 3 is turned over so as to cover L ₁ , and on top of that, the above-mentioned soil L _{3 is reversed and guided by the guiding plate part 2 of the front inverted tillage body a and leaves the rear end of the guiding plate part 2} . As shown in Fig. 6, the soil L1 is turned over by the soil turning plate 11, and the soil _L1 is turned over by the rear turning tiller b.
The soil L ₂ and the soil L guided by the guiding plate 2 of the front inversion tillage body a are divided into three parts, and the soil is inverted in the above-mentioned order in a state where the three layers overlap. The row reversal is now complete.

In FIG. 4, reference numerals 51 and 52 indicate the outer edges of the soil that are tilled by the front inversion tiller a when the uncultivated soil is tilled and inverted by the same-row inversion tiller A. The part that becomes the outer edge of the soil is tilled by the rear inversion tiller b. A vertical cut is made at the front of the body of the same row inversion tiller A so that the part that becomes the outer edge of the soil is cut in advance. It is a blade and is formed with a coulter. Further, 50 is a vertical cutting blade disposed at the front position of the inner end of the arched blade plate portion 10, and is formed by a coulter similarly to the vertical cutting blades 51 and 52.
