Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tillage section arrangement device in which the length of the attachment body is shortened and a tillage blade and a tillage blade are arranged at desired positions so as to be suitable for forming on a ridge with a narrow groove. .

Traditionally, narrow grooves (e.g., about 15 cI11 to about 20
In the case of forming a ridge (V-shape) with c#L), the tilling part is generally three blades on the circumference of a short tilling tube (mounting body) with approximately the same angular phase difference. (approximately 120°),
These were installed symmetrically on the left and right sides of the drive case and the ridge forming process was performed. These three mulch blades cannot drive in a perfect circle when tilling, resulting in large ups and downs, which not only has poor forward performance and maneuverability, but also makes it impossible to raise the ridge, resulting in extremely inefficient mulch tillage. was. For this reason, if six mulching blades are installed on the tiller with an angular phase difference of approximately 60°, a nearly perfect circular drive will be achieved, but the soil will get stuck between the adjacent mulching blades and the mulching function will not work. There was an unfortunate situation where the military was severely damaged, and as a result, it became impossible to advance immediately. Also, there were some that had five scraping blades on the outer periphery of the tiller, but
This had the drawbacks of 1) the soil becoming continuous and clumpy, requiring horsepower, and extremely poor progressability; It was considered technically impossible in the agricultural and farm machinery worlds to attach such a mulch blade to a short tiller tube and to arrange the mulch so that it could fully perform its mulching function.

Therefore, the present invention solves the problem of the mounting body having a short length.
Bringing the mooring blade and the second shoring blade close to the transmission case side\,
It is installed so that there is an angular phase difference of approximately 120°, and the third shoring blade is also installed around the axially intermediate circumference of the mounting body so that it has an angular phase difference of approximately 120° from the first ± shoring blade and the second shoring blade. Provided on the surface,
The trajectory of the mulching surface of the second mulching blade and the third ± mulching blade is made to be approximately spiral, and each of the first to third tilling blades is
The circumferential surface of the mounting body is mounted so that there is an angular phase difference of approximately 60° with each of the first to third ± shoring blades, and in the axial positional relationship of the mounting body, the first tilling blade is the first tilling blade. , the second and third tilling blades are provided a little outside of each of the second and third shifting blades, and close to the third and first shifting blades, and these are provided on both sides of the transmission case. By using a tilling section arrangement device that is symmetrically arranged and has its mulching surfaces and transverse portions facing outward on both sides, the three mulching blades and the three tilling blades have approximately the same angular phase difference ( (approximately 60 degrees), it is possible to drive in a nearly perfect circle, and the forward performance and maneuverability are favorable, and furthermore,
1st. The 2nd ± mowing blades are placed at the same position in the axial direction to narrow the width of the tilling, and the tilling blades also work to loosen the soil just before mulching, so even if they are arranged densely in the axial direction, There is no soil tension between the blade and the tilling blade, allowing extremely highly efficient soil tillage, which solves the above-mentioned drawbacks.Furthermore, when used with a ridge-forming board, high ridge-forming can be achieved. can be done in an orderly manner.

7c is configured such that there is an angular phase difference ζ of approximately 6 G' with each of the first to third ± erecting blades 6a, 6b, and 6c, and when the groove is driven to rotate, only three erecting blades are arranged. Unlike in the case where the wheel is installed, it is possible to drive in a substantially perfect circle, and there is only slight ups and downs during driving, making it possible to achieve extremely good forward performance and maneuverability. Furthermore, the first ± shifting blade 66 and the second ± shifting blade 6b are at the same position in the axial direction, and the three first ± third ± shifting blades 6's6b

Immediately after cultivating with
Immediately after cultivating the soil and loosening it well, you can use the 1st to 3rd 1st to 3rd 1st to 3rd grading blades 6g, 6b, 6g.
And, despite the fact that the first to third tilling blades 7g, 7b, and 7C are attached to the short mounting body 1 with a radial bar, there is no possibility of damage between adjacent mulch blades or between the mulch blade and the tilling blade. It is not difficult to cultivate the soil, and it is possible to perform extremely effective soil cultivation. In addition, by moving the bulwark surfaces P and P' and the transverse parts H and H' outward on both sides, the bulwark can be divided into two parts.
The use of a single mulch blade and three tilling blades is also effective when creating a narrow mulch width.

As mentioned above, the first to third ± of the three short mounting bodies 1-ζ
Approximately the same angular phase difference (approximately 60') is applied to the shifting blades 6g, 6b, 6c and the three first to third blades 7a, 7b, and 7C, respectively.

Each of the capes or these act synergistically, and for the first time, by arranging the mounding blade and tilling blade, we have solved the serious defect that conventionally made it difficult for experts to cultivate the mound, making it possible to achieve short width mounding tillage. Can be made highly efficient. If this type of tillage section arrangement device is attached to the furrow forming Fi8 with a green tip 9 as shown in Fig. 3, and the ridge forming work is performed, even with a small force source, high ridges can be formed. Top molding can be done in an orderly manner.

Note that even if the angular phase difference of the overwriting blade and tilling blade is changed by about 10', the same effect as described above can be obtained.
