Description

[Detailed description of the invention] This invention relates to a ridge forming machine.

When performing ridge forming work by attaching a ridge forming device to a traction machine or using a self-propelled ridge forming machine, in order to obtain a ridge of a certain size, the ridge must be shaped while always maintaining a fixed position from the ridge. It is quite difficult to make the molding machine run, and even if you operate it extremely carefully, the thickness of the coated soil is several tens of watts per inch.
Discrepancies of about 100 lbs. are unavoidable, and especially in a ridge forming machine in which a ridge forming device is installed behind the driver's seat, operation is difficult and tends to cause discrepancies in the size of the ridges.

Therefore, in this invention, an auger case is provided, which is equipped with a rotating soil scraping body and discharges the mud scraped up by the rotating soil scraping body onto the side of the ridge from the mud discharge port on the outside of the auger case. A ridge forming device having a ridge coating plate for applying soil to the sides of the ridge is attached to the traction machine body via a moving device so that it can be moved in the left and right direction, and is located in front of the mud discharge port in the direction of travel. A position detection device is installed to detect the position from the ridge to the ridge forming device by sliding on the side surface of the original ridge, and the position detection device and The ridge forming machine is configured with interlocking lateral movement devices, and the ridge forming device moves left and right in conjunction with the detection operation of the position detection device, and the thickness of mud applied by the ridge coating plate becomes constant and the traction machine is operated. It has been devised so that a certain ridge can be formed without requiring special care in operation.

The specific structure will be explained based on one embodiment shown in the drawings. From the frame 2 of the ridge forming machine attached to the traction machine 1, the sheath tube 3, for example, a rectangular cylindrical shape
One end of an inner tube 4 having a cross section similar to the inner hole of the sheath tube 3 is inserted into the sheath tube 3, and the other end of the inner tube 4 is equipped with a soil raising device such as an auger 5. The mud raked up by the rotation of the auger case 6 which internally supports the body 5 and the soil raising body 5 is discharged from the mud discharge port 6a on the outside of the auger case 6 to the side surface 9a of the ridge 9. A ridge forming device 8 consisting of a ridge coating plate 7 that applies the muddy soil to the side surface 9a.
The hydraulic cylinder 10, which has a smaller diameter than the inner hole of the inner cylinder 4, is inserted into the sheath cylinder 3 at the rear of the inner cylinder 4. The pressing piston 1 of the hydraulic cylinder 10 is fixed to the sheath cylinder 3.
Attach the tip of 1 to the rear of the inner cylinder 4, and install the hydraulic cylinder 10.
Left and right positioning devices 30 that can move the ridge forming device 8 together with the press piston 11 toward or backward from the ridge 9 by supplying or draining oil from one of the supply/discharge ports 12 and 13 that are visible at the front and rear of the press piston 11 inside. to form.

Further, a bracket 14 having an upright cylindrical bearing portion 14a at the tip extends forward from the other end of the inner cylinder 4 to which the auger case 6 is attached, and a sled-shaped bracket 14 that is retracted with respect to the traveling direction is provided. The base of the sensor 15 is attached to the lower end of a pin 16 that is pivotally supported in the inner hole of the bearing part 14a, and a two-way valve 17 with a neutral position is attached to the inner cylinder 4, and the pin 16 is made to protrude from the upper end of the bearing part 14a. An arm 18 is attached to the 2-way valve 17 , and the spool 19 of the two-way valve 17 is pivotally attached to the tip of this arm 18 .
The tip of the sensor 15 is connected to the side surface 9a of the original ridge 9 in front of the mud discharge port 6a in the traveling direction by communicating with the oil supply port 22 of the arm 18 and by tensioning a tension spring 23 between the arm 18 and the inner cylinder 4. As the ridge forming device 8 moves forward, the sensor 15 slidingly contacts the side surface 9a rotates the arm 18 around the pin 16 to move the spool 19 in and out. By switching the two-way valve 17 and supplying pressure oil before or after the pressing piston 11, or stopping oil supply, the ridge coating plate 7 of the ridge forming device 8 is adjusted so as to always maintain a constant distance from the ridge 9. It is.

In addition, a bevel gear box 26 that pivotally supports an input shaft 25 that is rotatably driven by the traction machine 1 is attached to the rear of the sheath tube 3, and a spline sheath tube 28 is connected to an output shaft 27 from the bevel gear box 26. The spline shaft provided on the auger manual shaft 29 for rotating the soil scraping body 5 is fitted and connected into the spline sheath tube 28 while keeping it parallel to the cylinder core of the sheath tube 3, and the ridge forming device 3 is moved in and out from side to side. First, rotational power is smoothly transmitted from the power agricultural machine 1 to the auger 5.

Therefore, even if the ridge 9 is curved and the traction machine 1 tries to continue moving straight, or even when the power agricultural machine 1 moves slightly away from or a little closer to the ridge 9, it will not move on the side surface 9a of the ridge 9. Since the sensor 15 in sliding contact rotates around the pin 16, the ridge forming device 8 moves left and right with respect to the frame 2 as the pressing piston 11 moves in and out as described above, so that the ridge coating plate 7 is always kept at a constant level from the ridge 9. Since the ridges 9 are located at intervals, it is quite easy to operate the traction machine 1, but the ridges 9 can always be formed to a constant size.
By changing the sliding contact position 5, the width of the ridge 9 can be adjusted as desired.

Note that when the ridge forming device 8 is not used, the operation of the position detection device 24 is cut off by blocking the oil supply passage from the hydraulic pump 20 to the two-way valve 17 with the shutoff valve 21.

As described above, the ridge forming machine according to the present invention is configured as described above, and is in sliding contact with the side surface 9a of the original ridge 9, and the position from the ridge 9 to the ridge forming device 8 is detected by the position detection device 24. Since the position detection device 24 and the lateral movement device 30 are configured in conjunction with each other to detect and maintain a constant gap between the mud discharge port 6a and the side surface 9a of the original ridge 9, the mud discharge port 6a and the mud The gap between the side surface 9a of the ridge 9 to be painted will be kept constant, and the mud discharged into this gap will be applied to the original side surface 9a of the ridge 9 at a constant rate by the ridge coating plate 7. The thickness of the newly formed ridges is always constant, and the density of the mud coating layer is also constant, resulting in a coating layer with a constant strength. It is possible to always form a constant ridge without requiring special attention to the operation of the machine.
