Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tillage ridge-erecting machine, and particularly relates to a tillage ridge-erecting machine equipped with a pressing roller that presses the top of the ridge.

(Prior art) A working machine that attaches a ridge former to a rotary tiller connected to a tractor and collects tilled soil and compacts it into a mound is disclosed in, for example, Japanese Utility Model Publication No. 57-3363. Disclosed.

(Problems to be Solved by the Invention) By the way, in the conventional example described above, there is no pressure roller that presses the tops of the shaped ridges, and therefore the tops of the ridges are uneven in shape. And yet,
It was relatively too soft.

Therefore, by providing a pressing roller at the rear of the molding machine, it is possible to press the top of the ridge, but if the pressing roller applies pressing force using its own weight or pressing force applying means, the ridge can be There was a risk that the shoulder portion of the surface would collapse.

The object of the present invention is to prevent soil from spilling even when the top of the ridge is pressed with a pressing roller.

(Means for Solving the Problems) The technical means taken by the present invention to achieve the above-mentioned object is that a ridge forming device is provided behind the tilling section, and a ridge forming device is provided behind the ridge forming device. In the device equipped with a pressure roller that presses the top, a soil spill prevention plate 19 corresponding to the ridge elevation surface is attached to each of the left and right side plates of the ridge forming device 4 so as to be able to swing vertically. A bullet 21 is provided which urges each of them to come into contact with the lower circumferential surface of the pressing roller 9.

(Function) The soil tilled by the tiller 2 is collected in the ridge shaper 4 and shaped into ridges 10 having a shape suitable for the type of crop, such as a semicylindrical shape or a trapezoid.

The top of the ridge 10 is compacted by the pressure roller 9, and the pressure roller 9 compacts the top of the ridge 10.
0's shoulder may lose its shape.

A pair of left and right soil spill prevention plates 19 are brought into contact with the lower peripheral surface of the pressing roller 9, thereby preventing the ridge 10 from deforming.
is energized by the ammunition 21,
It follows the vertical movement (vibration) of the pressing roller 9.

(Example) Embodiments of the present invention will be described in detail with reference to the drawings.

Reference numeral 1 denotes a rotary tiller, which has a tiller 2 such as a disc rotor, and is connected via a link mechanism 3 to a tractor (not shown).

Reference numeral 4 denotes a ridge forming device, which is provided at the rear of the tilling section 2 and attached to the tilling device machine frame 5 via a support 6, and is configured with a soil collecting section 7 and a forming section 8 opened in the front and back direction. ing.

A pressure roller 9 presses the top of the ridge 10, is longer than the width of the ridge 10, and is rotatably supported by the frame 11 perpendicular to the longitudinal direction of the ridge 10. It is arranged at the rear of the ridge forming machine 4.

In this embodiment, a frame 11 is vertically movably connected to the middle of an arcuate support rod 13 extending rearward from the machine frame 5 via a hitch fitting 12 via a horizontal shaft 11A. The supported threaded rod 15 is slidably inserted into the support portion 16 provided at the rear end of the arcuate support rod 13 at the lateral center, and the horizontal shaft 13 is rotated by the coil spring 17 fitted around the threaded rod 15. A frame 11 is biased at the fulcrum so that it can be lifted up.

Note that by screwing a nut 18 with a handle onto the threaded rod 15 and moving the nut 18 forward and backward on the threaded rod 15, the pressing force of the pressure roller 9 can be adjusted by adjusting the elastic force of the spring 17. The strength can be adjusted.

However, this is a preferable example, and the pressure roller 9 may be supported by a bracket fixed to the arcuate support rod 13, the support 6, etc., and even if the roller 9 is in the shape of a chain, there are no protrusions on the outer periphery. When it has a protrusion, it also has the function of perforating the ridge 10.

Reference numeral 19 denotes a pair of left and right soil spillage prevention plates, which are attached to the outer surfaces of both sides of the molded part 8 via pins 20 so as to be able to swing vertically, and extend rearward from the rear end of the molded part 8 to prevent the ridge 10 from rising. It corresponds to the surface portion 10A.

The upper edge bent portion 20 of each of the soil spill prevention plates 19 is pressed against the lower circumferential surface of the pressing roller 9 by a bullet 21, so that the soil spillage prevention plate 19 is always in contact with the lower peripheral surface of the pressure roller 9.

The strength of the ammunition 21 can be adjusted using an adjustment bolt 22, and is provided with a guide/swing regulating means 23 consisting of an arc hole centered on the pin 20 and a pin fitted into the arc hole.

In addition, in the illustrated example, the frame 11 includes a multi-film roll 24, a film guide roll 25,
A mulch (membrane covering device) is provided which includes a left and right pair of film treading wheels 26 and a left and right pair of soil covering bodies 27, respectively.

In addition, as shown in FIG. 1, a seeding device 29 may be provided between the pressure roller 9 and the mulch 28, and this seed delivery roll may be interlocked with the pressure roller 9 via a transmission mechanism 30 such as a chain. .

In addition, 31 is a gauge wheel, 32 is a film, 3
3 is soil covering.

(Effects of the invention) The present invention is characterized by the plowing by the tilling section 2 and the ridge forming device 4.
The ridge work is done continuously,
In this case, the top of the ridge 10 is compacted by the compression roller 9, and the ridge 10 can be formed into a well compacted ridge 10.

When the top part 10' is compacted by the pressing roller 9, the shoulder part tends to lose its shape, but this collapse is prevented by the soil spill prevention plate 19, and the prevention plate 19 is placed under the roller 9. Since the bullet 21 is provided in contact with the circumferential surface, the ridge 10 can be reliably compacted while improving the ability to follow irregularities together with the vertical swinging of the prevention plate 19.
