Description

[Detailed description of the invention] This invention relates to an agricultural groove cutting machine with a single-wheel drive source.

Prior Art In the conventional grooving machine, as shown in FIG. During the work, a couple of forces were generated between the groove cutter and the groove cutting plate 40 due to the deviation amount e, which had the disadvantage that the straightness of the agricultural groove cutter was hindered.

Purpose of the invention In order to eliminate the above-mentioned drawbacks, the purpose of the present invention is to use a single-wheel drive system that is capable of cutting grooves for drainage on the rice field surface Tm using the driving force of a single wheel that is offset and mounted on an oblique axis. By devising the original agricultural grooving machine, its gist was a support pipe 1 with a worm box WB diagonally connected to the front lower end along the vertical plane B-B passing through the longitudinal centerline of the machine; The engine En connected to the rear upper end of the pipe 1 and the groove plate 4 are arranged, while the grounding point 3a of the drive wheel 3 is arranged diagonally on the warm box WB so that it coincides with the lower part of the elevation B-B. The drive wheel 3 is mounted obliquely to the horizontal shaft 2 which is rotatably mounted on the horizontal shaft 2.

Structure of the Embodiment Hereinafter, an embodiment embodying the technical idea of the present invention will be described with reference to the drawings. In FIGS. 1 to 3, 1 is a support tube to which a warm box WB is connected to the front lower end. 1, and an engine En and a handle Hn are connected to its rear upper end.

Reference numeral 2 denotes a horizontal shaft inserted into the warm box WB, which is rotatably mounted on the A-A plane in FIG. 1, that is, upward to the right in FIG. is rotated through a gear train (not shown).

Reference numeral 3 denotes a drive wheel, which is attached to the output end 2a of the horizontal shaft 2 on the left side of FIG. However, the grounding point 3a of the drive wheel 3 is located below the vertical plane B-B.

Functions and Effects of the Embodiment Next, the functions and effects of the embodiment configured as described above will be specifically explained.

Now, elevation B- passing through the longitudinal centerline of the aircraft
The shaft is mounted obliquely so that the grounding point 3a of the drive wheel 3 is aligned with the lower part of the elevation B-B from a position offset from the same plane B-B with respect to B, and during groove cutting work,
The grounding point 3a of the drive wheel 3, which is the driving point, and the tip 4a of the groove cutting plate 4, which is the passive point, are shown in B-
Since it coincides with line B, even if the grooving machine is a single-wheel drive, the machine has excellent straightness and the grooving groove Vm cut by the grooving plate 4 becomes the desired straight line. This is also an effect unique to the present invention due to the unique configuration of the present invention.

That is, the present invention includes a support tube 1 in which a warm box WB is obliquely connected to the front lower end along the vertical plane B-B passing through the longitudinal centerline of the fuselage.
Engine En connected to the rear upper end of
While arranging the groove plate 4, the drive wheel 3 is connected to the horizontal shaft 2, which is rotatably mounted obliquely on the warm box WB, so that the grounding point 3a of the drive wheel 3 is aligned with the lower part of the vertical plane B-B. Because the structure is such that the shaft is mounted diagonally,
Despite its simple structure, it exhibits the above-mentioned effects and skillfully achieves the intended purpose of this invention, making it an extremely significant invention that contributes to improving the performance of agricultural groove cutters with single-wheel drive sources. It can be said that there is.

[Brief explanation of the drawing]

Figures 1 to 3 show an embodiment of the present invention, in which Figure 1 is a schematic side view of an agricultural groove cutter with a single-wheel drive source, and Figure 2 is a plane A-A in Figure 1. FIG. 3 is a plan view of FIG. 1. FIG. 4 is a schematic front view showing the drawbacks of the conventional machine in comparison with FIG. 2. Support tube 1, transverse shaft 2 drive wheel 3, groove plate 4 and elevation B-B.

Claims (1)
