Description

Detailed Description of the Invention In order to adapt the ridge standing board to the width of the ridge, the slope of the ridge shoulder, etc., the ridge standing board is separated into a front part of the ridge standing board and a rear part of the ridge standing board. The installation angle in the vertical direction is changed without changing the angle in the direction of movement of the ridge.The front part of the ridge standing board and the rear part of the ridge standing board that form the ridge standing board are separate, and the ridge standing board is The front edge of the rear part of the ridge board is brought close to the back side of the front part of the ridge board, and one side of a hinge is fixed to the lower edge of the rear part of the ridge board with the axis of the hinge facing approximately in the front-back direction. The other side of the ridge plate is fixed to both outer ends of the cross girders arranged to the left and right from the lower girder that protrudes rearward from the center of the bottom of the back surface of the front part of the ridge plate, and This invention relates to a ridge board characterized by being configured such that the mounting angle of the ridge can be changed and fixed at will.

To explain the embodiment with reference to the drawings, 1 is the front part of the ridge board and is placed behind the rotary tilling device. The outer edge of 2 is shaped so that the upper side becomes wider toward the end so that the width becomes wider as it moves upward, and 2 is an edge that is obtained by bending the left and right edges of the front part 1 of the ridge board diagonally backward. Reference numeral 3 denotes a support rod that is fixed in the vertical direction at the center of the back surface of the front part 1 of the ridge board. 4 is the rear part of the ridge-standing board;
is arranged so that its front edge is close to the back surface of the front part 1 of the ridge board, the lower edges are arranged approximately in the front-rear direction on both the left and right sides, and the upper edge is shaped to open outward as it moves toward the rear. Therefore, the rear edges of the left and right ridge plate rear portions 4 are formed in a shape that opens upward. Reference numeral 5 denotes a hinge, one of which is fixed to the lower edge of the rear part 4 of the ridge plate, and the other of the hinge 5 is fixed to the lower part of the support rod 3, and the lower part of the hinge 5 is fixed to the lower part of the support rod 3, which is protruded toward the rear. digit 6
The center part of the cross beam 7 is fixedly installed at the center part of the cross beam 7, and the left and right ends of the cross beam 7 are respectively fixed. Reference numeral 8 designates a connecting pin to which the hinge 5 is rotatably connected;
is facing approximately in the front-back direction. 9 is an opening/closing support rod that is fixed in the middle of support rod 3 and taken out toward the rear.
Reference numeral 10 denotes an opening/closing guide fitting which is fitted onto the opening/closing support rod 9 and is slidable back and forth and fixed at a desired position. Reference numeral 11 denotes an opening/closing support shaft 11' that protrudes from the opening/closing guide fitting 10 and is located at a position that coincides with the center line of the front part 1 of the ridge plate.
12, 13 are opening/closing rods, the inner ends of the opening/closing rods 12, 13 are supported by the opening/closing support shaft 11', and the outer ends are attached to the rear part 4 of the ridge plate in the middle of the upper part. Opening/closing rod links 14, 15 fixed at symmetrical positions
is connected so that it becomes a supporting shaft. Reference numeral 16 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. It is set up. Reference numeral 17 denotes an auxiliary plate which is vertically adjustable and fixed to the upper part of the rear edge of the rear part 4 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 standing board front part 1 and the ridge standing board rear part 4 that form the ridge standing board are separated, and the front edge of the ridge standing board rear part 4 is brought close to the back side of the ridge standing board front part 1, and the ridge standing board rear part 4 is One of the hinges 5 is fixed to the lower edge with the axis of the hinge 5 facing approximately in the front-back direction, and the other hinge 5 is provided to protrude rearward from the center of the lower back surface of the front part 1 of the ridge board. Since it is fixed to both outer ends of the cross beams 7 arranged on the left and right sides of the lower girder 6, and the vertical installation angle of the rear part 4 of both ridge standing plates can be changed and fixed freely, the installation angle of the rear part 4 of the ridge standing plate It is possible to stand up or bend outward, and change the size of the ridge. In other words, if the mounting angle is set up, the width of the ridge plate becomes narrower, and the size of the ridge becomes smaller. It is suitable for small ridges, and by twisting the mounting angle, the width of the ridge standing plate increases, and the size of the ridge groove increases, making it suitable for large ridges. Further, when soil cultivation is carried out, soil can be sent to the roots of the crops using the mounting angle of the rear part 4 of the ridge-standing plate and the auxiliary plate 17 provided at the upper part of the rear edge of the rear part 4 of the ridge-standing plate.

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 on the front edge of the rear part of the ridge standing board. When opening and closing according to the angle, 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 wide open, it becomes difficult to move the soil, so the traction resistance of the ridge board increases. However, since the ridge forming part forming the lower part of the rear part of the ridge standing board opens and closes at the same time, the width of the groove bottom changes. It was necessary to correct the groove bottom width each time it was adjusted.

However, according to the present invention, the rear part 4 of the ridge board is always at a constant angle with respect to the direction of travel, and the inclination angle is only changed by changing the vertical installation angle. Because it is constantly maintained, the resistance of the soil is almost constant and does not increase, so large amounts of power are not required. Also, because the soil moves well, you can finish the finished ridges neatly without overdoing it. Note that since the groove bottom width is always constant, there is no need to correct the groove bottom width each time the adjustment is made.

As described above, the present invention has the front part of the ridge-standing board and the rear part of the ridge-standing board made separately, 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 the lower edge of the rear part of the ridge-standing board. One of the hinges is fixed with the axis of the hinge facing approximately in the front-rear direction, and the other hinge is placed on the left and right sides of the lower girder that protrudes rearward from the center of the lower part of the back surface of the front part of the ridge plate. The vertical mounting angle of the rear of both ridge-standing plates can be changed and fixed at will, allowing the ridge-standing plates to be attached to the rear of a rotary tiller for ridge-raising work. When doing this, by changing the vertical installation angle of the rear of the ridge standing plate, the installation width of the rear of both ridge standing plates changes, so the required ridge work can be done according to the ridge width, and the soil cultivation work is improved. When doing this, by changing the mounting angle in the same way, the size of the upper end of the rear part of the ridge board becomes wider, allowing soil to be sent to the roots of the crops for cultivation. In this case, even if the vertical mounting angle of the rear part of the ridge board is changed, there is almost no change in the angle of the rear part of the ridge board with respect to the forward direction, so soil movement is always good, so even if various adjustments are made, There is little change in resistance to soil movement, and ridge work can always be performed well. In addition, since the width of the groove bottom does not change each time the width of the ridge board is adjusted, there is no need to correct the angle, unlike the molding board that forms the ridge side of the conventional ridge board. It has its features.
