Reference numerals 4 and 15 indicate opening/closing rods, the inner ends of which are supported by the opening/closing support shaft 13', and the outer ends thereof are fixed to the rear part 3 of the ridge plate at symmetrical positions in the middle of the upper part. Opening/closing rod links 16 and 17 are fitted together to form supporting shafts. Reference numeral 18 denotes a mounting rod that is inserted into and fixed to an insertion hole (not shown) of a work equipment mount provided at the rear end of the rotary tiller, and the angle of the mounting rod 18 and support rod 2 can be adjusted only in the front-back direction. It is attached to. Reference numeral 19 denotes an auxiliary plate that is vertically adjustable and fixed to the upper part of the rear edge of the rear part 3 of the ridge plate and extends diagonally rearward.

Next, to explain its effect, when the ridge-erecting plate of the present invention is attached to the work equipment attachment provided at the rear end of a rotary tiller attached to a tiller, etc., and ridge-erecting work is performed at the same time as tilling, the ridge-erecting The front part 1 of the ridge-standing board and the rear part 3 of the ridge-standing board that form the board are separated, and the front edge of the rear part 3 of the ridge-standing board is brought close to the back side of the front part 1 of the ridge-standing board, and inward in parallel to each other on the left and right. It is bent to form an edge 4, the lower edge of the rear part 3 of the ridge plate is arranged approximately in the front-rear direction, and an axis is provided approximately parallel to the lower edge of the rear part 3 of the ridge plate so that it can rotate freely. The other side of the hinge 5 is fixed to the lower part of the support rod 2, and the guide girder 7 is fixed to the rear end of the lower girder 6 that projects rearward. Fixed in the direction,
The left and right cross beams 8 and 9 are fixedly inserted into the guide beam 7 so that they can move in and out only in the lateral direction, and are fixed to the outer lower ends of the left and right cross beams 8 and 9, so that the ridge Due to the structure that allows the vertical mounting angle of the rear part 3 of the ridge standing plate to be freely changed and fixed on both the left and right sides, the vertical mounting angle of the rear part 3 of the ridge standing plate can be set up or turned outward. Can change shape. Therefore, if the mounting angle is set up, the inclination angle of the ridge side surface will rise and the ridge spacing can be narrowed, making it suitable for small ridges, and if the mounting angle is made curved, the inclination angle of the ridge side surface will be curved, thereby making it possible to narrow the ridge width. In addition to being able to adapt to the ridge, the cross beams 8 and 9 are fitted into the guide beam 7 from the left and right, and are fixed so that they can be moved in and out only in the lateral direction. In other words, if the crossbeams 8 and 9 are moved in parallel to the left and right outwards and fixed, a ridge with a wide groove bottom can be created, and if the crossbeams 8 and 9 are moved inward, respectively. A ridge with a narrow groove bottom width is created. Therefore, the size of the ridge and the groove bottom width of the ridge can be combined in a wide variety of ways and varied over a wide range. Further, when carrying out soil cultivation work, soil can be sent to the roots of the crops by the mounting angle of the rear part 3 of the ridge-standing board and the auxiliary plate 19 provided at the upper part of the rear edge of the rear part 3 of the ridge-standing board.

The conventional opening/closing type ridge standing board had the front part of the ridge standing board connected to the rear part of the ridge standing board, and was opened and closed centering around the front edge of the rear part of the ridge standing board, so the rear part of the ridge standing board was connected to the rear part of the ridge standing board. When opening and closing according to the size, the angle of the rear part of the ridge board with respect to the forward direction changes, which changes the flow of soil.If the angle is opened too wide, soil escape becomes poor and the resistance of the ridge board increases. In many cases, a large amount of power is required, and the width of the groove bottom will change if the rear of the ridge plate is opened and closed, so the lower edge of the rear of the ridge plate must be adjusted each time to adjust the width of the groove bottom appropriately. In addition, changing the groove bottom width and opening and closing the ridge board using the same ridge board would be structurally difficult and would require a very narrow range. However, according to the present invention, the rear part 3 of the ridge board is always at a constant angle with respect to the direction of travel, and by changing the vertical installation angle, only the inclination angle changes, so the angle at which soil can easily escape can be adjusted. Because it is constantly maintained, the resistance of the soil does not increase, so large amounts of power are not required. Also,
The soil can easily escape, so there is no need to force it, and the finished ridges can be made neatly.In addition, the front edge of the rear part 3 of the ridge standing plate is bent inward on both the left and right sides to form the edge 4, so that the ridge can be easily finished. It is possible to move left and right or change the angle of inclination only in the area where the front plate part 1 and the edge part 4 overlap, and also to change the angle of inclination.
can be moved in and out only laterally and can be fixed at the required position, so it is easy to adjust the interval between the lower edges of the rear part 3 of the ridge plate to the desired width of the groove bottom, making it possible to create various types of ridges. It is now possible to easily adjust it to suit the shape of.

As described above, the present invention separates the front part of the ridge-standing board and the rear part of the ridge-standing board that form the ridge-standing board, brings the front edge of the rear part of the ridge-standing board close to the back side of the front part of the ridge-standing board, and It is fixed to one side of a rotatably formed hinge with its lower edge facing approximately in the front-rear direction, and the other side of the hinge is attached to a lower part that protrudes rearward from the center of the lower part of the back surface of the front part of the ridge plate. The rear part of the ridge board is fixedly installed at the outer lower end of the cross girder arranged from the girder to the left and right, and the vertical mounting angle of the rear part of the ridge board can be changed and fixed freely on both the left and right sides. The leading edge of each has an edge facing inward, and the base of the cross beam is fixed to the guide girder fixed to the lower girder in the left and right direction so that it can be moved in and out only in the lateral direction. When performing ridge work with this ridge standing board attached to the rear of the rotary tillage device, by changing the vertical mounting angle of the rear part of the ridge standing board, the mounting angle of the trailing edge of the rear part of the ridge standing board can be adjusted. Since this changes, it is possible to carry out the required ridge work according to the ridge width, and when performing soil cultivation work, by similarly changing the mounting angle, it is possible to cultivate soil up to the roots of the crops. In this case, even if the mounting angle of the rear part of the ridge plate is changed in the vertical direction, there is almost no change in the angle of the rear part of the ridge plate with respect to the forward direction, so the flow of soil is not affected. Therefore, even if various adjustments are made, there is little change in the resistance to soil movement.
In addition to being able to perform ridge work at all times, once the width of the groove bottom of the ridge is adjusted to the required width, even if the vertical mounting angle of the rear of the ridge plate is changed and adjusted, the groove bottom remains unchanged. There is no need to make any adjustments because the width of the line remains almost the same. However, since the structure is designed to allow the width of the groove bottom to be changed, a combination of adjusting the vertical mounting angle of the rear part of the ridge plate and adjusting the left-right distance of the lower edge of the rear part of the ridge plate, that is, widening or narrowing the width of the groove bottom of the ridge. This has the advantage that ridges can be formed in a wide variety of shapes depending on the desired ridge spacing, size, height, etc.
