Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perforating device for a multi-ridge transplanter for planting soiled seedlings such as lettuce while making holes in a multi-membrane covering the ridge.

[0002]

2. Description of the Related Art As a perforating device for a multi-membrane,
There are those disclosed in the specification and drawings. In this conventional technique, a flame receiving member having a flame outlet is provided below the flame ejecting pipe via a spacer, and a heat-conductive cylinder is provided on the lower surface of the flame receiving member so as to project downward. The multi-film body, which is vertically movable to cover the ridges, is configured to be burned off by the cylinder and simultaneously burned off by a flame.

[0003]

In the above prior art, a gap is provided between the flame ejection pipe and the flame receiving member in order to send air to the flame and to escape the flame that has heated the flame receiving member. However, when the wind is strong, the wind blows into the gap, the pilot fire extinguishes, the flame is laid sideways, the heating performance of the flame receiving member deteriorates, and the flame exceeds the surroundings of the flame receiving member. It may open a large hole in the multi-membrane.

According to the present invention, the upper part of the tubular body is projected from the flame receiving member toward the flame jetting pipe, and the flame escape hole between the flame jetting pipe and the flame receiving member is covered from the outside. It is an object of the present invention to provide a punching device for a multi-ridge implanter capable of solving all the problems.

[0005]

The concrete means for solving the problems in the present invention is to provide a flame receiving member 142 having a flame ejection hole 144 at the lower end of the flame ejection pipe 140, and to conduct heat conduction to the flame receiving member 142. A multi-film body Q in which a possible cylindrical body 143 is provided so as to project downward, and is vertically movable to cover the ridge N.
In the punching device of the multi-ridge transplanter for making a hole 116 in the ridge, the upper part of the cylindrical body 143 projects from the flame receiving member 142 to the flame ejection pipe 140 side, and the outside of the flame escape hole 145 of the flame ejection pipe 140 is provided. It is covering.

[0006]

[Operation] The gas flame constantly ejected from the flame ejection tube 140 is
The flame receiving member 142 is hit and heated, and the cylindrical body 143 is heated by heat conduction. The gas flame hitting the flame receiving member 142 escapes outward from the flame escape hole 145 at the lower end of the flame jetting pipe 140 and hits the rear part of the cylinder 143 to heat it.

The rear portion of the cylindrical body 143 projects upward from the flame receiving member 142 toward the flame jetting pipe 140 side, and wind blows through the flame escape hole 14
Prevent entry into 5 and prevent the flame from the flame outlet 140 from extinguishing. When the cylindrical body 143 comes into contact with the multi-film body Q on the ridge N, the heat power of the gas flame increases, and the flame receiving member 14
The multi-film body Q is burnt out by ejecting it through the second flame ejection hole 144.
