The soil is cut into 〓, the cut 〓 is turned approximately 90 degrees on the spot by a mold board installed at the rear of one side of the horizontal cutting blade, and then the cut 〓 is turned approximately 90 degrees on the spot by a guiding member installed at the rear of the horizontal cutting blade. A plowing and reversing device comprising a horizontal cutting blade and a mold board provided on one side of the same, and a multi-unit plowing and reversing device in an on-spot reversing tillage work machine configured to rotate the blade in the direction of rotation and reversing it on the spot. Concerning improvements to type in-situ reversing tillage machines.

As shown in FIGS. 1 and 2, the in-situ inversion tillage machine of the above-mentioned form has a machine that cuts the soil substantially vertically at the front end of the machine body a to make a substantially vertical cut in the soil. Vertical cutting blades 1... are mounted in parallel at intervals corresponding to the left and right widths of the 〓 to be formed, and behind the interval between the vertical cutting blades 1... A horizontal cutting blade 2 that cuts the soil approximately horizontally at a depth position corresponding to the lower end is provided, and on one side of the rear of the horizontal cutting blade 2, the vertical cutting blade 1 and the horizontal cutting blade are arranged. 2. Cut the lower corner of one side of L from the soil with the third
As shown in Figures A, B, and C, the mold board 3 is pushed up diagonally upward on the other side, and the L is turned approximately 90 degrees in the groove M formed by cutting the L.
... is disposed, and on the other side opposite to the mold board 3..., a pushing member 4 for pressing the upper surface of the other side of the rotating (reversed) L is disposed, and furthermore, the horizontal cutting blade 2 The lower end of the L, which has been flipped approximately 90 degrees to the rear position as shown in FIG. In addition to providing a mold board 5 for guiding extrusion in the reverse direction,
A pressing member 6 is provided that presses the upper end of the L that is reversed by the mold board 5 from the opposite side to the mold board 5, and thereby the L cut from the soil is It is configured to be reversed on the spot.

In the in-situ inversion tillage machine of this type, there are a horizontal cutting blade 2 which works together with the vertical cutting blade 1 to cut L from the soil, and a horizontal cutting blade 2 which works together with the horizontal cutting blade 1 to cut the cut L from the soil. The mold board 3, which is rotated approximately 90 degrees, is reciprocated approximately along the longitudinal direction of the machine body in order to forcibly and rapidly reverse the L on the spot (within the groove M formed after cutting the L). It is supported by the shank 7 which is provided to swing (vibrate), but when configuring it in a multiple type in which the shank 7 is arranged in parallel on the left and right in the same phase, as shown in FIG. On both sides, two horizontal cutting blades 2, 2 are attached in the form of wing plates with a swept angle in plan view, and one side of the shank 7 of the horizontal cutting blades 2, 2 (left side in the example) The horizontal cutting blade 2 located at It is effective to provide a mold board 3 at the end, thereby configuring the tilling and reversing device A as a two-unit unit, and to arrange a desired number of unit plowing and reversing devices A in parallel on the left and right sides. be.

By the way, the unit tillage and reversal device A configured in this way has a shank 7 as shown in Fig. 4.
On the left side of , when 〓L, which is cut by the horizontal cutting blade 2 and is lifted by the lifting angle of the horizontal cutting blade 2, is reversed approximately 90 degrees with the mold board 3, the 〓 Since L is reversed by the mold board 3 in the flow direction along the inclination angle (sweeping angle) of the front edge of the horizontal cutting blade 2 in plan view, the movement of L is natural and the reversal is performed smoothly. However, on the right side of the shank 7, the direction in which L flows along the front edge of the horizontal cutting blade 2,
Since the directions in which 〓L is reversed by approximately 90 degrees in the mold board 3 are opposite to each other, a disadvantage arises in that 〓L cannot be reversed smoothly.

The present invention solves this problem by arranging tilling and reversing devices consisting of a horizontal cutting blade 2 and a mold board 3 provided at one end of the horizontal cutting blade 2 on both sides of the shank 7 in the same phase. It is an object of the present invention to enable each of the left and right tillage and inversion devices to smoothly invert 〓L, while configuring a two unit tillage and inversion device A by installing the device in this way.

The means of the present invention for this purpose includes horizontal cutting blades 2, 2 installed on both left and right sides of the shank 7.
When viewed from the rear, the front edges 2a, 2a of the horizontal cutting blades 2, 2 are along a substantially horizontal plane, and the rear edges 2b, 2b thereof are gradually higher toward the end side where the moldboards 3, 3 are located. The present invention is characterized in that it can be installed in a state to constitute a unit tillage and reversal device.

To be more specific according to the drawings of the embodiment, the fourth
As shown in the figure, horizontal cutting blades 2, 2 are formed on both left and right sides of the shank 7 so that their front edges 2a, 2a form a wing plate shape with a swept angle α in plan view. It is installed with a lifting angle so that the rear edges 2b, 2b side rise relative to each front edge 2a, 2a, and the edge of the horizontal cutting blade 2 on one side (the left side in the figure) on the shank 7 side. The mold board 3 is installed at the end opposite to the shank 7 of the horizontal cutting blade 2 on the other side (the right side in the figure), and the two-unit type tilling and reversing device A is installed. When configuring the horizontal cutting blade 2 (horizontal cutting blade 2 on the left side in Fig. 4) in which the moldboard 3 is provided at the end on the shank 7 side, as shown in Fig. 5, the rear side The leading edge 2a of its trailing edge 2b in vision
The height H relative to the shank 7 is installed so that it gradually increases toward the shank 7 side, so that the connection part with the shank 7 is the highest, and the mold board 3 is provided at the end opposite to the shank 7. As for the horizontal cutting blade 2 (horizontal cutting blade 2 on the right side in Fig. 4), as shown in Fig. 5, the height H with respect to the trailing edge 2b and the leading edge 2a when viewed from the rear is equal to the shank 7. It is installed so that it becomes gradually lower toward the side, so that the connection part with the shank 7 is the lowest. At this time, the height H ₁ of each trailing edge 2b, 2b of the highest end of the left and right horizontal cutting blades 2, 2 on the side where the moldboards 3, 3 are provided,
H ₁ is the same, and the heights H ₂ and H ₂ of each trailing edge 2b, 2b at the end opposite to the side where the lowest mold boards 3, 3 are provided are also the same (in this case, The height of the trailing edge 2b of the horizontal cutting blade 2 where the moldboard 3 is provided at the end opposite to 7
H ₁ is the height H ₁ of the trailing edge 2b of the horizontal cutting blade 2 on the other side
It may be made higher. ).

Next, FIGS. 6 and 7 show that the two unit tillage and inversion devices A shown in FIGS. 4 and 5 described above are
In contrast to the configuration in which L is inverted to the left, an example is shown in which L is inverted to the right. This example is shown in Figures 4 and 5.
In contrast to the example shown in the figure, the horizontal cutting blades 2, 2 disposed on both the left and right sides of the shank 7 and the mold boards 3, 3 disposed on one end of each of them are symmetrically provided, and the structure is They are exactly the same.

Next, FIG. 8 shows the above-mentioned unit tillage and reversal device A.
The figure shows an example in which a multiple type on-spot reversing tillage work machine B is constructed by combining the following in multiple series so as to be parallel to each other in the same phase on the left and right sides. In this example, unit tillage and reversal devices A are arranged in two rows (three or more rows may be arranged in parallel) so that they all reverse and guide L in the same direction. , as shown in Fig. 9, the four 〓Ls are simultaneously reversed on the spot in the same direction, so that flat furrow plowing can be performed continuously without soil movement.

In addition, the irregular type in-situ reversing tillage work machine B shown in FIG. Two types of tillage and reversal devices are used, and they are paralleled in two series (or in multiples), and at that time, each unit tillage and reversal device A directs L towards the center of the parallel direction As shown in FIG. 2B, a large number of L. In addition,
In this type of multi-unit reversing tillage work machine B, when the number of parallel unit tillage reversing devices A is an even number, the same number of reversed L's are directed toward the center of the rows. However, when the number of units of the unit tillage reversal device A is a constant number, the number of 〓L... to be reversed toward the center will be larger on either the left or right side, and the center of the ridge will be Becomes biased to the left or right. b is a vibration device that vibrates each shank 7;

b, 2b are installed so that they gradually become higher toward the end side where the moldboards 3, 3 are located, so the horizontal cutting blades 2, 2 provided on both the left and right sides of the shank 7 have a receding angle in plan view. In particular, the horizontal cutting blade 2 is shunted at the end opposite to the side where the mold board 3 is located. Since the reversal of L on the side connected to shank 7 is made so that L flows and reverses the direction, L can be smoothly reversed in the same way on either the left or right side of shank 7. This enables a desired number of unit plowing and reversing devices A to be installed in parallel at the same phase.

From this, by combining multiple unit tillage and inversion devices A in parallel, a multi-in-situ type that can perform ridge plowing and flat ridge plowing in a single process without moving the soil. A reversing tillage machine will be available.
