Description

DETAILED DESCRIPTION OF THE INVENTION The present invention has a structure in which the length of the mounting body is made relatively short, and soil mulching blades and tillage blades are arranged at desired positions so as to be suitable for molding on ridges having relatively narrow grooves. The present invention relates to a tillage section arrangement device.

Traditionally, relatively narrow grooves (e.g., about 2051 to about 2
In the case of ridge-like (V-shaped) forming with a length of 5 tx), the tilling part has a relatively short length of 3
If we set up the main blades with approximately the same phase difference (approximately 120°) and set them symmetrically on the left and right sides of the drive case to perform soft soil forming work, then with the three blades, When plowing, it is not possible to drive in a perfect circle, resulting in a large undulating drive, which not only has poor forward performance and maneuverability, but also makes it impossible to raise the ridge, resulting in extremely inefficient plowing. Therefore, if six mulch blades are used and attached to a relatively short tilling tube with an angular phase difference of approximately 60°, a nearly perfect circular drive will be achieved. If the soil contains a lot of soil or the soil has some viscosity, the soil will certainly become clogged, resulting in the drawback that the soil levitation function will not work at all, and it may become impossible to move forward in a short period of time. There was also a tiller with two screw blades attached to the outer periphery of the tiller, but this had the disadvantage that the soil was continuous in lumps9, required horsepower, and had extremely poor forward performance. 1 Attach the mulch blade to a relatively short tilling tube,
Traps should be placed so that they can fully perform their earth-harvesting function.
A friend that is considered technically impossible in the agricultural and agricultural machinery worlds.

Therefore, the present invention provides the following features on the peripheral surface of a mounting body having a relatively short length:
11g1 to 3rd ± shoring blades are placed in positions that are sequentially away from the transmission case side and are installed so that an angular phase difference of approximately 1200 is generated, and the locus of the shoring surface of the first to third ± shoring blades is approximately spiral. The first to third tilling blades are attached to the horse face KNR of the mounting body so that the angular phase difference is approximately 60° with respect to the first to third plowing blades, and the second.
Chin 3. The first tilling blades are also positioned so as to gradually move outward from the transmission case side, and are symmetrically provided on both sides of the transmission case, with the ground surface and transverse portion thereof being formed outward on both sides. The three mulching blades and the three tilling blades have approximately the same angular phase difference (approximately 60°), allowing for approximately perfect circular drive, and favorable forward performance and maneuverability. By making the locus of the earthing surface approximately spiral, the earthing function along this path is mn.

Within the range of the relatively short mounting body, it is possible to maintain the space between the mulching blade and the tilling blade to the minimum necessary so that the soil does not get stuck, and it is possible to mulch the soil while cultivating the soil. It allows for highly efficient lateral tilling and eliminates the above-mentioned drawbacks, and furthermore, if used in combination with a ridge-forming board, high ridge-forming can be done in an orderly manner.

The structure is illustrated in drawings.

1 is a metal mounting body with a rectangular (hexagonal, etc.) or circular cross section, and may be cylindrical (see drawing) or solid shaft-shaped, and the length in the axial direction is relatively short. A through hole 2 (generally formed with the inner diameter of the pipe) is provided in the center of the cross section of the cylindrical mounting body l, and a through hole 2 (generally formed with the inner diameter of the pipe) is provided below the agricultural power traveling machine 3 such as a tiller or a tractor. Mounting bodies 1, 1 are removably installed in a symmetrical manner to tilling shafts 5, 5 protruding from both sides of the protruding transmission case 4 through their through holes 2. (9) The solid shaft-shaped mounting body l is integrated with the tilling shaft 5, and may be referred to as the tilling shaft 5 itself. 6., 6&, 6# respectively are the 1st. Second. The third blade has a plate shape, and the width of the blade suddenly increases from the mounting base side to the middle of the tip side. ,

The second tilling blade 7h is in the same position as the first ± shifting blade i-, #I3
The tilling blade 7c is at an intermediate position between the first mulching blade 6g and the second ± mulching blade 6&, and the first tilling blade 76 is at a position equal to or slightly closer to the second ± mulching blade 6h than the third mulching blade 6C. (See the solid line position in Figure 2). In addition, as shown in the dotted line position in Figure 2, the first tilling blade 7s is moved to the second ± shifting blade 6.
Sometimes it is placed close to the number. In this way, the right tilling section is configured. In addition, the left tillage S (see the left side figure in Fig. 2) where the mulching blade etc. is installed on the left side is the first to third mulching blades 6g, 64° 6I with the mulching surface P''.

The loci of P, P-P', F, and P' form a substantially spiral shape, and can fully demonstrate the mulch function. At the vertical cutting part (■) on the base side, the soil is cut into each piece and turned over in a spiral to perform earth mulching, so that the soil clods do not become continuous, and this makes it possible to turn over and bury the earth smoothly. In particular, the use of three pressures is also effective when taking into account the relatively narrow width of the dam, and good forward performance can be achieved without requiring large horsepower (driving force). Also, the second. Third. 1st cultivation blade 7&.

The tilling blades 76 are recently or relatively close to each other in the axial direction (the third ± shifting blade 6C and the W and I tilling blades 7a may be separated), and have an angular phase difference of about 180°, The soil is removed with the tilling blade, and later, it has the effect of shoring up the soil, and the soil does not get stuck between adjacent shoring blades or between the shoring blade and the tilling blade, allowing for excellent soil tilling. .

In addition, it is possible to cultivate the soil and separate both IIIVC and P.? This is due to the fact that the horizontal portions H and B are directed outward.

As described above, the relatively short mounting body 1 has three first to third scouring blades 6s, 5'4.6g and three first to third
The tilling blades 7g and 74.7g have approximately the same angle phase difference (approximately 60

Moreover, by making it into a spiral shape, it can be installed on the relatively short mounting body 1, S can also be reversed in a spiral shape, and the soil gathering function can be sufficiently performed. It is possible. ■Tear surface P,? The horizontal part H2 is turned outward on both sides and can be divided into the surface side so that the soil can be piled up, etc., or these can act synergistically to solve the serious defect that conventionally, the soil was stuck and could not be plowed. The arrangement of the mulching blades of the invention solves the problem for the first time, and makes relatively short width mulching tillage extremely efficient.This type of tilling section arrangement device can be used on a ridge with 9 cutting points as shown in Fig. 3. Molded plate 8
By attaching it to the ridge and performing work on the ridge, even with a small power source, it is possible to form the ridge with a high height in an orderly manner. Even if changed, the same effect as above is achieved.
