Description

[Detailed description of the invention] This invention relates to a ridge forming device configured to secure soil necessary for covering the strip film near the foot of the ridge when forming the ridge. It is.

The soil for this covering is done by removing the base of the ridge when forming the ridge and filling it with the scraped soil that has accumulated at the edge of the ridge, but behind the completed ridge board, something like a scraping board is installed for shaving the base of the ridge. The total length of the furrowing device becomes excessive, which is inconvenient when turning, and the center of gravity of the rotary and the furrowing device, which is suspended in an overhang at the rear of the tractor, moves further rearward. This results in a decrease in stability when traveling during work.

Therefore, this invention is proposed to solve this problem, and its configuration will be explained based on one embodiment shown in the drawings. , 2 and a vertically swingable rear cover 3 so that a ridge 4 can be roughly formed, and left and right forming ridge plates whose front lower ends are pivotally connected to the rear lower part of the ridge standing plates 2, 2 with pins 5, 5. 6,6
is rotatable in the vertical direction along the arcuate groove 6a, and
A stay bolt 7 interposed between the ridge plate 2 and the ridge plate 6 allows the gap between the left and right ridge plates 6 and 60 to be adjusted so that the rear part becomes narrower as shown in Fig. 3. The left and right side surfaces 4a, 4a of the held ridge plates 6, 6 and ridge 4 are configured to be compacted.

Therefore, in this invention, a notch 6b is provided at the rear lower part of each ridge board 6, and a bracket 9, which also serves as a reinforcing bone, is fixed to the outer side of the earthen board 8, which has a shape that matches the notch 6b. , the bracket 9 of the earth mooring board 8 is superimposed on the bracket 10 fixed to the growing ridge board 6 above the notch 6b, and the pin 11 fixed to the bracket 9 is connected to the bush 12 of the bracket 10 of the growing ridge board 6. By fitting loosely into the earthen board 8
is formed so that it can be rotated left and right around a pin 11, and a bolt 13 fixed to the bracket 9 of the earth mooring board 8 is inserted into the arcuate groove 10a provided in the bracket 10 of the ridge board 6. If you tighten the screwed nut 14, the clay panel 8,
8 are fixed at their respective rotational positions, and as shown in FIG. 8 is fixed, the side surface 4a of the ridge 4 that is being formed by the ridge plates 6, 6.

It becomes possible to scrape off the hem of the ridge 4a with the clay panels 8, 8 and move the scraped soil 15, 15 to the outside of the hem of the ridge 4. When fixed in parallel to 66, the growing ridge board 6 and the earthen veneer board 8 are configured so as to form a ridge without a scraped portion.

Note that the rotary 16 illustrated in FIG.
The lift arm 1 of the lifting device 18 attached to the rear of the
The rear cover 3 is constructed so that the plowing depth can be adjusted by lifting and rotating the tillers 9 and 19. , the upper surface of the ridge 4 is press-molded by a press spring 23 wound around a press rod 22.

Since the ridge forming device according to this invention is constructed as described above, the left and right soil panels 8, 8 are pinned in such a position that the front parts of the soil panels 8, 8 approach the center of the ridge 4. 11, 11 and tighten the pads 14 and 14 to fix the soil panels 8, 8, the hem of the ridge 4 that is being formed by the ridge board 6°6 will be covered with this soil. This scraped soil 15, 15 will be scraped off at the front part of the veneer board 8.8, and this scraped soil 15, 15 will be deposited on the outside of the foot of the ridge 4 by the rear part of the soil veneer board 8, 8, which is located in a rearward-spreading manner. become.

Therefore, in the subsequent work of laying the film strip, by lining up the left and right outer sides of the film strip covering the ridges 4, the scrapers 15 and 15 can be scraped together and covered with the covering wheel.

In addition, in the ridge work that does not require such scraped soil 15, 15, the cutouts 6b, 6b are closed by fixing the earth mooring boards 8, 8 in parallel to the ridge boards 6, 6, so that the scraped portions are not removed. This results in the formation of normal ridges.

To change the working posture for scraping the ridge hem or to the normal ridge forming working posture, loosen the oaks N4 and 14 a little and move the clay panels 8 and 8 as described above. Adjust the rotation to the specified position and tighten the nut again.
This is completed by tightening the handles, and the work position can be changed extremely easily.

In addition, since it is not necessary to remove the clay panels 8, 8 from the ridge panels 6, 6, there is no risk of them being lost.

Moreover, these clay panels 8, 8 are formed at the notch 6 of the ridge board 6.6.
Since it is provided so as to rotate within b and 6b, the ridge plate 6
, 6 do not protrude at all to the rear of the ridge-growing device 8, 8, so the overall length of the ridge-growing device does not become excessive, making it convenient for turning operations. This also results in better performance.
