Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sowing method and a sowing device for crushing the plowing plate below the topsoil plowed by a rotary with a blade hanging down into the ground, and subsequently performing a sowing operation. It is something.

When sowing root vegetables such as radish and burdock, the top soil is plowed widely using a rotary wheel, and the roots of the root vegetables are straightened by crushing the plow plate below the sowing area into a narrow width. I try to stretch it out and help it grow. However, the soil in the area where this plowing was done is more compact than other areas, so if the rear cover of the rotary is used to roughly level the surface of the plowed soil and sowing, the plowing can be done. As the areas where the seeds are sown become compacted due to subsequent watering and rainwater, depressions will form in the topsoil of the seeding areas above, and rainwater will accumulate in these depressions, causing the seeds to rot before they germinate. There are problems such as the seeds may get burnt and the roots are prone to rot even after germination.

Therefore, this invention is proposed in order to solve these problems in the conventional ones, and is to crush the plowing plate below the topsoil plowed with a rotary with a blade 9, and to crush it with the blade 9. This is a seed method in which seeds are sown on a mound 22 formed on the ridge surface of
In addition, the rotary 2 is provided so that the blade 9 crushes the plowing plate below the topsoil plowed by the rotary 2.
A recessed part 20a corresponding to the path of the blade 9 is formed on the lower edge of the rear cover 20, and a rotary rotor is attached to the sowing ridge in which a mound 22 is formed of soil that rises from this recessed part 20a. This is a seeding device in which the seeding section of the connected seeding machine 33 is provided behind the rear cover 20 so as to correspond to the seeding section.

Next, one example of the specific structure will be explained based on the illustrated embodiment. As shown in FIG. The rotary 2 can be moved up and down together with the lower links 3, 3 via lift rods 7, 7 by lift arms 6, 6 which are pivotally connected by a link 4 and rotated up and down by a hydraulic actuation mechanism 5. ing.

A blade 9 is suspended underground behind the tiller 8 of the rotary 2, and a horizontal fulcrum pin 12 is connected to the middle of a mounting arm 10 attached to the upper part of the blade 9 to the mast 11 of the rotary 2. The upper part of the mounting arm 10 is pivotally connected to an arm 13 fixed to a rotating body of an eccentric rotation mechanism (not shown) with a pin 14, and the rotational power of the power take-off shaft 15 of the agricultural tractor 1 is When this is transmitted to the input shaft 16 of the rotary 2, the cultivating body 8 rotates and the rotating body of the eccentric rotation mechanism reciprocates the arm 13 back and forth, so that the mounting arm 10 is connected to the fulcrum pin 12.
An excavating body 17 configured to vibrate the blade body 9 in the front-rear direction with the blade body 9 as the center and fixed at the bottom of the blade body 9 is designed to crush the plowing plate below the topsoil that is tilled by the tiller 8. . Further, the upper part of the cultivating body 8 is covered with a rotary cover 18, and the rotary cover 1
A rear cover 20 whose upper edge is hinged to the rear part of the tiller 8 with a hinge 19 collects soil scattered by the tiller 8 and roughly levels the ridge surface 21.

Therefore, as shown in FIG.
0a... are provided respectively, and the soil scattered by the tiller 8 during plowing and the soil raked by the rear cover 20 protrude from the recessed portions 20a, and are slightly removed from the ridge surface 21. Long mound part 2 of mounded ivy
2... are formed near the passing locus of each blade body 9.

Then, as shown in FIGS. 1 and 2, the upper edge of the auxiliary cover 23, which is large enough to cover the recessed notch 20a, is pivotally attached to the rear cover 20 with a hinge 24, and are provided so that the auxiliary cover 23 can be rotated to open and close up and down, and a pin hole 25 is provided in the rear cover 20 near the bottom of the recessed notch 20a.
By inserting a pin (not shown) into 25, the auxiliary cover 2
3 is restrained from upward rotation by this pin, the recessed notch 20a is closed by the auxiliary cover 23, and the raised part 22 is prevented from being formed.

Next, the auxiliary cover 26 shown in FIG.
Although it is hinged to 0, the left and right side plates 26a, 26a
are provided on the auxiliary cover 26, so that the left and right side surfaces of the raised portion 22 can also be pressed by the side plates 26a, 26a.

Furthermore, in each figure of FIG.
The auxiliary cover 28, which can be inserted into and moved up and down along the guide pieces 27, 27, opens the recessed part 20a,
Alternatively, the presser bolts 29, 2 may be formed so as to be closed.
9 allows the auxiliary cover 28 to be fixed.

Note that the rear parts of the left and right vertical rods 30, 30, which are pivotally connected to the rear part of the rotary 2 in FIG.
3 are connected. Also, this seeding machine 33 has drive wheels 3
4, rotate the seeding belt 35 and release the seeding hopper 36.
Seeds 37 that have fallen into the concave portion 35a of the seeding belt 35 from the opening in a fixed amount are transferred to the raised portion 2 by the grooved disc 38.
The structure is such that the seeds are sown in a shallow trench opened in 2.

Further, this seeding machine 33, which is movable up and down around a pin 39, is configured so that its inclination in the front and back direction can be adjusted by angle adjustment bolts 40.

Therefore, when the input shaft 16 is rotationally driven, the tilling body 8 rotates and tills the topsoil, and since the blade body 9 vibrates back and forth around the fulcrum pin 12, the tilling body 17 plows the soil. This will shatter the board. At this time, the tilled soil is roughly leveled by the rear edge of the rear cover 20 to form a ridge surface 21, but the plowed soil is roughly leveled by the rear edge of the rear cover 20 to form a ridge surface 21. Therefore, a raised portion 22 is formed near the path of the blade 9.
It should be noted that these raised portions 22 are somewhat shaped by the auxiliary cover, thereby forming seeding ridges. Seed is then sown into this mounded part 22 by a subsequent seeding machine 33, and the mounded part 22, which is slightly raised above the ridge surface 21, is not likely to become lower due to subsequent rainwater, etc. Even if there is rainwater, it will not become lower than the surrounding ridge surface 21, so this rainwater etc. will not accumulate.

The seeding method and seeding device according to the present invention are for crushing the plowing plate below the topsoil plowed by the rotary 2 with the blade 9 as described above.
The subsequent blade 9 can dig easily, requiring less digging power, and weeds and straw on the ground can be removed by the blade 9.
Even if the rotary rotary 2 is engaged, weeds and the like will be easily removed from the blade body 9 by the soil scattered during plowing, and the weeds and the like will be buried due to the plowing by the rotary 2.
Seeds are sown in the smoothly formed sowing ridges on the surface of the raised part 22 formed by the concave notch 20a of the rear cover, so that weeds and the like are not exposed, so that germination is uniform and subsequent growth is improved, and the seeding process is improved. The tiller part below the ridge is narrowly crushed by the blade 9, so that the roots of the root vegetables can be straightened and the commercial value of the root vegetables can be increased.
