Description

[Detailed description of the invention]

TECHNICAL FIELD The present invention relates to rotary tillage, and more particularly to a rotary 1#1 rotary tiller that can operate at high rotation speeds and requires less power.

[Follow! technology】

On the periphery of the horizontally supported II rotary wheel of the conventional Keyachi,
In a rotary tiller II device equipped with a large number of II plowing claws, the II plowing claws are arranged so that their horizontal blades protrude from the same ring circumference in approximately the same number on both the left and right sides. If you try to work with a large tilling pitch by increasing the rotation speed (working speed) of the shaft, the tilling claws will not penetrate the soil sufficiently and will act to push the tractor by accelerating the forward movement speed. So-called Datsusing jJ! You can't wake up an elephant and make a high-speed craft like 7 lau. Further, if the rotational speed of the tilling shaft is increased to keep the ah pitch small, it becomes possible to perform high-speed work to some extent, but this is not preferable because the gk force becomes significantly large. Furthermore, there are models with a tilling shaft that is installed obliquely with respect to the direction of execution of the machine, but in this case, it is possible to perform soil mulching work that moves the tilled soil to one side, but the tilling claws are arranged horizontally as described above. Since the blade protrudes on both the left and right sides, there is the same problem as mentioned above.

[Problem 1 to be solved by R-ming] The present invention was made in consideration of the above circumstances, and allows high-speed plowing work even with 1ml rotary plowing, and can be done with less power. It is an object of the present invention to provide a rotary tillage device as described above. "Means for Solving the Problems" In order to achieve this object, the present invention provides the conventional rotary tiller, in which a large number of #l tillers curved in the same direction are disposed around the tiller shaft. It is characterized by the fact that

[For use]

By having the above configuration, the rotary tillage device of the present invention can work on a forced drive disc plow and stubble without causing a dashing phenomenon even if the tilling shaft is rotated at high speed, and the required power is also lower than that of conventional ones. Rotary If &
This is much less than li If.

【Example】

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a rotary tiller 1#1, and a main body frame 2 of the rotary tiller 1 is provided with a tractor attachment mechanism 3 that protrudes forward and is attached to a three-point link hitch mechanism of a tractor (not shown). The main body frame 2 is attached to the tractor mounting mechanism 3 obliquely in the direction of movement of the rotary tiller 1. Also,
An input shaft 4 is located at an intermediate position in the left and right direction of the main body frame 7 2.
A tilling shaft 8 is pivotally supported in parallel to the main body frame 2 between power transmission side frames 6 and side frames 7 which are vertically disposed downward from both ends of the main body frame 2 . Rotational power transmitted from a tractor (not shown) to the human power shaft 4 passes through the main body frame 2 and is transmitted to the tilling shaft 8 via the transmission side frame 6. A stabilizing wheel 9 is attached to the side frame 7 toward the rear. The tilling shaft 8 has, as shown in FIGS. 2 and 3,
A large number of flanges 10 (10 are shown in FIG. 1) are fixed at predetermined intervals, and on the outer periphery of these seven flanges 10,
A large number of holders 11 (eight in FIG. 2) are provided at regular intervals, and a tilling claw 12 is attached to each holder 11. The tilling claws 12 are different from conventionally known machete claws in that they are curved at a substantially constant curvature from the mounting base to one side, and the tilling claws 12 attached to each flange 10 are arranged so as to curve in the same direction. (See Figure 1). In the rotary tilling system 'e41 having such a configuration, the tractor attachment mechanism 3 is attached to the three-point link hitch mechanism of the tractor (not shown), power is transmitted from the PI-0 shaft of the tractor to the input shaft 4, and the gear box 5 and the main body are connected. The tilling shaft 8 is moved in the forward direction in FIG. 1 through the frame 2 and the transmission side frame 6.
Plowing work is performed by rotating in the direction of the arrow in Figure 2. At this time, the rotational speed of the l'l private shaft 8 is lower than that of the conventional tilling shaft. Each of the tilling claws 12, 12... works to drive into the soil from above, and the front ones make cuts in the soil in the vertical direction, and at the same time, they also move the tilled soil laterally. The displacing force acts to create horizontal cracks in the soil. In this way, the soil is tilled with large clods, almost independently of the so-called tilling pitch. In the case of the rotary tiller of the present invention, in order to make incisions in the soil smoothly, the rotation speed of the tiller shaft is increased depending on the working speed as described above, but this makes it possible to make incisions in the soil smoothly. Unlike rotary tillers, the soil is not unnecessarily broken down into smaller pieces, so less power is required. On the other hand, if you try to perform high-speed tilling with a conventional rotary tiller, as mentioned above, the only way to reduce the required power is to increase the tilling pitch, making it impossible to avoid the dashing phenomenon. If the tilling pitch is reduced, the required power will increase. In addition, compared to the action of a multi-disc plow with a strong III drive type, it penetrates the soil better, and the production cost of tilling claws is considerably lower than the production cost of a disc plow. . Note that since the tilling shaft 8 is oblique to the direction of movement of the machine, a force lateral to the direction of movement is generated.
This force can maintain good maneuverability of the tractor by rolling the stabilizing wheels 9 onto uncultivated land.

【Effect of the invention】

As is clear from the above description, according to the rotary tilling device of the present invention, a large number of i-shaped grooves curved in one direction on the axial circumference (7 langes) of the tilling shaft installed obliquely in a horizontal plane with respect to the direction of travel.
Since the tiller claws are installed, even if the tiller shaft is rotated at high speed,
The tilling claws have good driving performance into the soil, and highly efficient tilling work can be carried out without causing the douching phenomenon. In addition, the required power can be reduced, and the I
ll 耘验 also has the advantage of being able to be produced and supplied at low cost.
