Description

[Detailed description of the invention] The present invention uses a ridge forming device that is connected to the rear of a tillage device attached to a tractor to form ridges, and uses flat and high ridges with a flat upper surface to form ridges that are necessary for crop planting. The height and width of the ridge can be adjusted within a wide range to create a suitable ridge, and the horizontal plate that smooths the top surface of the ridge can be deformed.
It is an object of the present invention to provide a ridge forming apparatus that can form ridges having a gentle chevron-shaped cross-sectional shape, so that it is possible to form ridges with more suitable ridge shapes.

An embodiment will be described with reference to the drawings. Reference numeral 1 denotes a tilling device having a tilling section 2, which is towed behind a tractor (not shown) by a three-point link 3 or the like.
The tilling section 2 is a rotary tilling blade that rotates around a horizontal horizontal axis, and has the function of cultivating the ground surface, crushing the soil, and softening the soil.

The auxiliary forming plates 15, 15' are bridged by this. or,
The leveling plate 17 has an earth guard plate portion 19 that slides into rear end edge of each of the left molded plate 7 and the right molded plate 7'. 2
0 and 20' are box metals that are fitted onto the horizontal rods 4, and support rods 2 that extend horizontally and to the same length rearward at the bottom of each.
1 and 21' are fixed respectively. Reference numeral 22 denotes a cross beam installed horizontally in parallel with the leveling plate 17, and bolts 25 are attached to the mounting brackets 23, 23', and 24 protruding from the left and right ends and the center of the horizontal plate part of the leveling plate 17. ，
It is screwed on at 26 and 27. 28, 28' are vertical rods whose lower ends are fixed to the cross beam 22, and support rods 21,
21' and the vertical rods 28, 28', the horizontal part and the vertical part are perpendicular to each other, and the through fittings 29, 2 are attached to each of them.
The leveling plates 17 are fitted into the orthogonal holes 9', respectively, to fix the leveling plate 17 against parallel movement in the vertical and front-back directions. Reference numeral 30 denotes an earth-proof plate, which serves to supplement the earth-proof plate part 19 when the leveling plate is at a low position, and supports the support rod 2.
1 and 21', and are fixed to fittings 32 and 32' bent on the lower surfaces of the through-holes 31 and 31', which are fitted onto the outside of the holes 31 and 21', and are pressed against the rear edges of the left molding plate 7 and the right molding plate 7', respectively. ing. Reference numeral 33 indicates a notch made in the earth protection plate part 19 to enable the leveling plate 17 to bend downward using the lower end of the mounting bracket 24 as a fulcrum in the horizontal plate part 18. Elongated holes 34 and 34' are formed in the left and right end fittings 23 and 23', respectively, and the fittings 23 and 23' are pushed down so that the horizontal plate part 18 has an arbitrary curved shape. It is possible to fix it. Reference numeral 35 denotes a connecting fitting that connects the connecting member 36 stretched at the rear of the tilling section 1 and the horizontal rod 4, and 37 denotes a connecting pin. Arrow A indicates the direction of travel. A two-dot chain line B indicates the curved shape of the leveling plate 17. A shows the soil that has been tilled and crushed by the tiller 2, and b shows the ridge formed by the forming plate.

Next, to explain the operation, in the ridge forming device of the present invention, the tilling section 2 of the tilling device 1, which is towed behind a tractor (not shown) by a three-point link 3, tills the ground surface as the tractor advances. It is connected to the rear of the tillage device 1 in order to crush the soil to create expansive and soft soil, move it toward the center, and shape the soil into desired ridges. The left molded plate 7 and the right molded plate 7' arranged on the left and right sides of the horizontal rod 4 are the box metal 5,
By moving and adjusting 5' to the left and right, the facing interval between the left molding plate 7 and the right molding plate 7' is adjusted, and the ridge width is set. The height of the ridge is determined by connecting the auxiliary forming plates 15 and 15' to the left and right bolt insertion holes 16 drilled at the same height on the left and right sides at the rear ends of the left forming plate 7 and right forming plate 7', respectively.
The auxiliary molding plates 15 and 1 are installed at the horizontal plate part 18 of the leveling plate 17 through the holes at the required height positions, respectively.
The leveling plate 17 is constructed so that the left and right sides are bridged by the almost horizontal curved surface of the plate 5', and the soil protection plate part 19 is brought into sliding contact with the rear edge of the left molded plate 7 and the right molded plate 7'. The through fittings 29, 29' are fitted onto the support rods 21, 21' so that the horizontal parts of the through fittings 29, 29' can be moved back and forth, and the vertical positions of the through fittings 29, 29' can be adjusted. , 29' are vertically adjusted and fixed to set the ridge height. According to the above, left and right molding plates 7, 7'
The ridge width and ridge height can be adjusted within a wide range at will by adjusting the width and raising and lowering the auxiliary molding plates 15, 15'. In addition, the auxiliary forming plates 15, 15'
is made by combining a large number of bolt insertion holes 16 drilled at the same height in the vertical direction at the rear ends of left and right molded plates 7, 7' and elongated holes provided in auxiliary molded plates 15, 15'. It can be installed at any height, and the ridges can be finished without destroying the ridge shoulders due to the curved extension of the auxiliary forming plate.
The soil prevention plate 30 is used in combination to compensate for the fact that when the height of the leveling plate 17 is low, the soil prevention plate part 19 alone cannot prevent the soil from being scattered from the plowing part 2. If the height of the shield plate 17 is at a high position, it is therefore unnecessary, and the earth guard plate 30 can be removed.

In addition, by making a plurality of notches 33 (three in the illustrated examples in FIGS. 2 and 3) in the soil protection plate portion 19, the leveling plate 17 can be bent downward using the lower end of the mounting bracket 24 as a fulcrum. Since the bolts 25 and 26 inserted into the long holes 34 and 34' drilled in the mounting brackets 23 and 23' can be screwed at any position in the long holes 34 and 34', the mounting brackets 23,2
3', that is, by bending and fixing the leveling plate 17 downward as shown by the two-dot chain line in FIG. 3, it is possible to form a ridge with a gentle mountain-shaped upper surface.

With the structure and operation described above, this invention allows you to change the ridge width from a very low ridge to a high ridge by assembling only one set of ridge forming members, which is not possible with conventional products. A wide variety of ridge heights and ridge widths can be combined. Furthermore, since the upper surface of the ridge is flat or the ridge has a gentle cross-sectional shape of a medium-high mountain shape, it can be handled without replacing the left and right molding plates or leveling plates. Most of the work of creating ridges of slightly medium to high shape can be done with only one set of ridge forming members. In addition, it is easy to handle and provides a good finish to the ridges without damaging the ridge shoulders.
