Description

[Detailed description of the invention] The present invention relates to improvements to plows.

Plowing is the work that consumes the most energy in land preparation work using plows.

[1] The purpose of the present invention is to reduce the energy required for this plowing, so that the plow can be moved with less power required for traction.
-1 is to be made possible.

Plowing involves plowing, crushing, and turning, but plowing consumes the most energy, and is said to consume one-third to one-half of the total energy used for plowing. There is. Therefore, if the energy required for plowing can be reduced, the energy required for plowing can be effectively reduced.

The present invention is based on this point. 1) The plow is designed so that the energy required for plowing during plowing operation is reduced.
This is based on the results obtained through repeated research. In other words, forming the blade plate of the plow in an arch shape to reduce the IJi upper plowing cross-sectional area and lowering the specific resistance is effective in reducing the power required for pulling the plow (about 10"% reduction). Since we obtained certain results, we proposed a plow in which the central part of the blade plate is formed in an arch shape with several arcuate curves on one side when viewed from the front.

Regarding the embodiments in the drawings, the layers will be explained in detail:
1 and 2 show a plow A according to the invention. Plow A has a beam (1), a ground plate (2), and a blade plate (3).
), it is the same as a conventionally known plow in that it is composed of a repellent ZTh plate (4), but its blade plate 13)
As shown in FIG. 1, the left and right central portions W are curved upward in an arc shape, and are formed into an arch shape when viewed from the front as shown in the sectional view of FIG. 3. The central part W of the blade plate (3) curved upward in an arc shape is the maximum +1 in the left-right direction at the cutting edge (3a) of the blade plate (3).
] is about 150 millimeters, and the cutting edge (3
The maximum height seen in a) is approximately 60 mm. In addition, in the embodiment shown in FIGS. 1 and 2, the central portion W of the blade plate (3) curved in an arc shape is such that the ridgeline thereof is as shown in FIG. ) is formed parallel to the blade surface (3b), but when the ridge line is formed parallel to the horizontal plane as in the embodiments shown in Figs. 5, 6, and 7. There is also. In addition, this figure 5 and 6
In the embodiment shown in the figure, the central portion W of the blade plate (3) curved in an arc shape in three directions has a maximum rl+ of about 110 millimeters on the left and right sides of the blade edge (3a). l
The maximum height at the cutting edge (3a) is approximately 55 millimeters.

Therefore, the plow A configured in this way has a beam (1
) is connected to a towing vehicle for plowing work, it works as follows.

■ The plowing cross-sectional area on the tower is smaller than that of a normal plow, reducing specific resistance.

■ The top of the tower is cut into an arch shape at a portion corresponding to the center of the blade plate (3).

■ As the soil repellent plate (4) rises, tensile failure occurs in a direction parallel to the soil repellent plate (4). This is because the flame is cut in an arch shape by the cutting edge (3a) of the blade plate (3), so a cavity is created when it starts contacting the soil repellent plate (4), and this cavity is crushed, causing σ [This is due to tension failure occurring. This tensile fracture improves the crushing performance and reduces the traction force of the plow.

Therefore, the energy required for plowing can be reduced, and the plow 1v can be operated with a small required power for traction.

Therefore, in this means of the present invention, the arcuately curved central portion W of the blade plate (3) causes the soil cut from the soil to form residual tillage in the field.

The embodiment shown in FIGS. 1 and 2 and FIGS. 5 and 6
In the embodiment shown in the figure, a small plow a placed behind the central part W of the blade plate (3) and on the back side of the soil repellent plate (4) is used to spread the soil into the field using the soil cut from this soil. This is a means to dispose of the remaining tillage that is forming. This small plow a is located at the above-mentioned position with the beam of plow A (1
) or supported appropriately by a mounting frame provided on the mast connected to the beam fl). The remaining tillage is moved by the small plow a to the upper side of the embankment where the plowing was reversed by the plow A, and fills the cavity in the lower part of the plow Ill-1'.

Therefore, when the small plow a is disposed behind the central part of the blade plate (3), there is no problem of the soil cut from the plow forming residual tillage.
