Description

[Detailed Description of the Invention] The present invention relates to a ridge forming device that is connected to the rear of a tiller or a tilling device attached to a tractor, etc., and forms ridges. In order to be able to form ridges in a wide variety of shapes, such as flat and high ridges and chevron-shaped ridges, which cannot be formed with conventional tunnel-shaped ridge formers, the upper left forming plate is used to form the upper surface of the ridge. , consists of three molded plates: a right upper molded plate and a center upper molded plate, and the left upper molded plate and the right upper molded plate are each tilted so that the front edge side is higher than the rear edge side, and the left and right molded plates are The outer sides of the molded plates are fixed, and the rear edges of the upper left molded plate and the upper right molded plate are narrowed diagonally upward to the front. It is an object of the present invention to provide a ridge forming device characterized in that it can be fixed movably in the front and rear directions while bridging the ridge.

To explain the embodiment with reference to the drawings, 1 is a connecting fitting disposed at the rear of a tilling device (not shown) attached to a tiller or a tractor, etc.;
The rear end is fixed to the horizontal rod 4, and the front end is attached with a connecting fitting 1.
A connecting part 3 that is fitted inside and fixed so as to be slidable up and down.
5 and 5' are box metals that are fitted on the left and right sides of the horizontal rod 4 and fixed so that the position can be freely adjusted in the left and right direction, and 6 and 6' are box metals 5 and 5 whose upper ends are connected to the box metals 5 and 5, respectively. This is a leg that is fixed and hung from the bottom surface of the 7 and 7' are left-right symmetrical ridge side forming plates, each of which has a front edge that can receive soil tilled by a tiller and send it inward by rotation of a rotary tiller blade (not shown). Fix the front plates 8, 8' which have been made into
It is fixed to the legs 6, 6'. The upper edges of the ridge side molded plates 7, 7' are configured to form a slope of high front and low rear.
Reference numerals 11 and 11' denote a left upper molded plate and a right upper molded plate that are bilaterally symmetrical and are bent inwardly, and
The bent surfaces 12, 12' have respective slopes, and the outer surfaces 13, 13' are the ridge side molded plates 7, 7'.
Fixedly installed in an adjustable height position. Reference numeral 14 indicates a fixing screw component. In addition, 15 is a ridge side molded plate 7, 7'
A general term for the holes drilled in the hole for inserting and tightening screw parts.
The rear edges of the upper left molded plate 11 and the upper right molded plate 11' face each other and are inclined so as to narrow diagonally upward toward the front. Reference numeral 16 denotes a central upper molded plate bridging the upper left molded plate 11 and the upper right molded plate 11', and the central upper molded plate 16 has a symmetrical divided structure of a left leveling plate 20 and a right leveling plate 20'. None, long holes 2 connected to each other with screw parts 21
2, 22', which are overlapped and fixed in the left and right directions at the inner side to form an integral central upper surface molded plate 16.
The bent surfaces 12, 12' are provided with 2 to 3 in the front and back directions so that they can be slid freely in the front and rear directions on the inclined surfaces of the bent parts 12, 12' and fixed at a desired position. A large number of holes 18 for inserting and screwing screw parts 17 are bored in three rows at regular intervals. In addition, a plurality of similar holes 19 are bored horizontally in the center upper molded plate 16, and the left and right ridge side molded plates 7, 7' are left and right along with the upper left molded plate 11 and the upper right molded plate 11', respectively. It shall be possible to move, adjust the spacing to obtain the required ridge width, and fix it.
A indicates the direction of travel. (The above distinction between "left" and "right" refers to the direction of travel.) A is soil that has been crushed and expanded by a tiller. b indicates a molding ridge.

Next, to explain the operation, the connecting part 3 at the front end of the connecting rod 2 is fitted into the connecting metal fitting arranged at the rear of the tilling device attached to a tiller or tractor, etc., and the tiller is towed. In order to form the crushed and softened soil a into the required ridge b, the ridge side forming plates 7 and 7' arranged on the lower left and right sides of the horizontal rod 4 are moved to the box metal 5,
Set the ridge width by adjusting and fixing 5' evenly on the left and right sides. Next, the left upper surface molding plate 11 and the right upper surface molding plate 1
Select hole 15 so that 1' is the required ridge height,
It is fixed to the left and right ridge side molded plates 7, 7' with screw parts 14, respectively. Next, the center upper molded plate 16 is passed over the respective bent surfaces 12 and 12' of the upper left molded plate 11 and the upper right molded plate 11', and is slid back and forth to form the hole 18 so as to obtain the desired height and shape of the ridge. By selecting and aligning the holes 19 on the central upper forming plate side and bridging and fixing with the screw parts 17, the required ridge forming device is constructed, and the function of forming the ridge as the tiller or tractor advances. to do. If the holes 15, 18, 19, etc. are long holes (not shown) in the illustrated arrangement direction, the height and width of the ridge can be finely adjusted, so that the shape of the ridge can be further diversified. That is, as shown in FIG.
1' are fixed to the upper parts of left and right molding plates 7 and 7', respectively.
By moving the central upper molding plate 16 forward and bridging and fixing it to the upper left molding plate 11 and the upper right molding plate 11', a mid-high ridge as shown in FIG. 4 can be formed, and as shown in FIG. As shown in FIG. 3, the left upper molding plate 11 and the right upper molding plate 11' are lowered slightly lower than in the case of FIG. upper left side molding plate 11
By bridging and fixing it to the right upper molded plate 11', it is possible to form a trapezoidal flat and high ridge with a flat upper surface of the ridge as shown in FIG.

With the structure and operation described above, the present invention uses a set of ridge formers, and by assembling and adjusting its constituent members, the ridge can be changed from a ridge with a flat upper surface to a ridge of flat height with a trapezoidal shape. By assembling and adjusting each component, we can create ridges of a wide variety of widths, heights, and shapes, such as chevron-shaped ridges, which are completely impossible with conventional high-ridge ridge formers or flat-high ridge formers. This ridge forming machine is effective in forming a wide range of shapes.
