Description

[Detailed description of the invention] The present invention relates to an automatic lotus root digging machine.

Lotus roots, which have been used as food since ancient times, cannot be mechanized because they run criss-crossed in deep muddy fields.For this reason, lotus root digging is done using traditional tools: a banku that removes the soil, and does not damage the lotus roots. Currently, the digging is done carefully using oysters and other tools. Since one's feet would get stuck in the mud in the muddy field, one would have to make a path by connecting boards called ``Ayumi-ita'' one by one. For this reason, the work was hard labor and required patience.

The present invention was made in order to reduce the labor of digging lotus root, which is such a heavy labor. The nozzle moves left and right on a rail extending perpendicular to the running direction of the float as it digs, and uses the lightness of the lotus root itself to powerfully spray the lotus root buried in the soil. To provide an automatic lotus root digging machine which naturally floats up when water digs up the lotus roots and harvests them.

An embodiment of the lotus root digging machine of the present invention will be explained with reference to the accompanying drawings. FIG. 1 shows a perspective view of the whole, and FIG.
The figure shows the same plan view. In the figure, 1
is a float made of synthetic resin or light alloy. 2 is an engine mounted on the float 1, and 3 is a winch that winds a wire 8 driven by the engine 2. This wire 8 is tied at one end to a stake 9 driven into a ridge in the field, and when the engine 2 is driven and the winch 3 is rotated, the wire 8 is wound up by the winch, and the float 1 is thereby It is something that runs. Reference numeral 4 denotes a rail attached to the rear of the float 1, and is attached so as to extend by an appropriate length in a direction perpendicular to the traveling direction of the float. Reference numeral 5 denotes an injection nozzle that reciprocates left and right on the rail 4, and is connected with a vinyl hose to a main water supply pipe 6 provided on the float 1 in the same straight line as the direction in which the wire 8 is pulled. The other end of this main water supply pipe 6 is connected to a vinyl hose 6' connected to a well C dug in a ridge at another location in the field. Also, the reference numeral 7 in the figure is an auxiliary nozzle that is used by operating the switching valve at the base of the main water supply pipe 6.Nozzle 5 is normally used for the operation, but if lotus roots are left un-digged. This is done manually by turning the switching valve to the auxiliary nozzle side. As mentioned above, the lotus root digging machine of the present invention has various devices mounted on the float 1, and when the engine is driven, the water jet from the winch's wire winding nozzle is activated simultaneously to start the work. Ru. In FIG. 3, A and B are diagrams of the embodiment, B is a diagram of the embodiment, A is a plan view, B is a plan view, and B is a side view. As can be understood from the figure, the float 1 moves in the direction of the arrow A by winding the wire 8, but in this case, in the present invention, the injection nozzle 5 is arranged at right angles to the direction of movement A of the float 1. rail 4
Since the main pipe 6 for water supply is fixed on the same straight line as the pulling direction of the wire 8, the float moves from the well C which meander depending on its position. It is possible to move straight without receiving resistance from the vinyl hose 6', and uneven digging of lotus roots does not occur.

In the present invention, the advancing speed of the float is approximately 35 to 75 cm/min, depending on the field conditions and the depth of the lotus root, and the speed of one reciprocation of the nozzle is
17 to 37 seconds is appropriate.

Since the lotus root digging machine of the present invention works automatically as described above, by repeating the back and forth movement of the float, the work can be completed in a short time even in a large lotus field, which is compared to conventional heavy labor farming. It is a device that can efficiently perform lotus root digging, which is a representative example of this, and has an extremely outstanding effect in that it does not damage the lotus root because it uses jet water to dig up the lotus. I believe that this will bring significant results to the lotus root digging work.
