Description

  The present invention relates to a pressing pin used mainly for agricultural multi-sheets.

  Conventionally, a method for covering a culture medium or cultivated land with a covering material for the purpose of raising the ground temperature, preventing grass, etc. is known. Agricultural multi-sheets are known.

  In order to stretch this agricultural multi-sheet on the ground surface, a holding pin having a linear shaft has been used conventionally. However, in this pressing pin, the shaft pushed into the ground is linear, so Since there is no resistance when it is pushed in, it easily enters the ground, but it is easy to enter, and there is a problem that the sheet may be blown by the wind.

Object of the invention

The first object of the present invention is to increase the resistance in the ground by corrugating one shaft part that enters the ground of the holding pin and horizontally rotating the head when pushed into the ground. An object of the present invention is to provide a multi-sheet holding pin for agriculture that prevents the pin from being easily pulled out.

The second object of the present invention is to make the portion of the presser pin that enters the ground into a bifurcated shape consisting of two U-shaped shafts, and to increase the resistance in the ground by the spread of the two shafts in the ground. It is another object of the present invention to provide an agricultural multi-sheet pressing pin that prevents the pin from being easily pulled out.

Means for solving the problem

  In order to achieve the first object according to the present invention, the pressing pin of the agricultural multi-sheet according to claim 1 has a corrugated one shaft entering the ground of the pressing pin and is pushed into the ground. Sometimes the head is horizontally rotated to increase the resistance in the ground to prevent the pin from being easily pulled out.

  According to a second aspect of the present invention, there is provided the agricultural multi-sheet pressing pin according to the second aspect of the present invention, wherein the portion of the pressing pin that enters the ground is bifurcated with two U-shaped shafts. The feature is that the resistance in the ground is increased by the spread of the two axes in the ground to prevent the pin from being easily pulled out.

Effect of the invention

  In the first aspect of the invention, since one shaft portion that enters the ground of the pressing pin has a corrugated shape, when the head is pushed into the ground and the head is rotated horizontally, the shaft portion of the pin rotates horizontally. A plurality of horizontal grooves different from the vertical grooves formed when being pushed into the ground are formed in the ground, and are prevented from coming off by the resistance between the corrugated portion of the shaft and the soil.

  In the second aspect of the invention, the portion of the presser pin that enters the ground is formed into a bifurcated shape composed of two U-shaped shafts. Therefore, when the two shafts are constricted, they are pushed into the ground. Among them, the two shafts expand to the left and right, and the two shafts and the soil are prevented from being pulled out.

  In this embodiment, the head 3 for pressing the sheet is integrally formed by a single metal wire. However, the head 3 is a washer formed of a separate synthetic resin or the like as shown in FIG. Of course, it is also good.

  The axis | shaft 2 is shape | molded by the waveform shape which has the some vertex part 2-1, The head 3 is circular and the knob | pick part 3-1 is formed.

  The press pin 1 according to the invention of claim 1 is configured as described above, and is formed on the shaft 2 when the tip of the shaft 2 is stabbed into the agricultural multi-sheet S stretched on the ground and pushed into the ground. The wave-shaped apex portion 2-1 at the lowermost end and the portion connected to the bottom penetrate into the ground while pushing out the soil D.

  As the corrugated apex portion 2-1 of the shaft 2 of the presser pin 1 and the portion connected thereto intrude into the ground while pushing out the soil D, a vertical flat groove is formed in the soil D.

  In this state, if the picking part 3-1 of the head 3 is held and the heel is pulled up, the pressing pin 1 can be pulled out without any resistance through the vertical flat groove formed in the soil D first. After the shaft portion 2 is pushed into the ground, the knob portion 3-1 is grasped and rotated horizontally (preferably 90 ° rotation). Since 1 and the part connected to this push out the soil D, a plurality of horizontal grooves are formed in the soil D.

  In a state where the knob 3-1 is gripped and rotated horizontally (preferably 90 ° rotation), a plurality of corrugated apex portions 2-1 to 2-1 of the shaft 2 are connected to this. Since the upper part of the part is clogged with soil, even if an attempt is made to pull out the holding pin 1 by grasping the knob 3-1, an extremely large force is required due to the resistance of the soil, and the agricultural multi-sheet S is drowned in the wind. The force that has just been applied does not cause the head 3 to be pressed and peeled off.

  When the agricultural multi-sheet S is peeled off, the holding pin 1 can be easily pulled out by grasping the knob 3-1 and returning the holding pin 1 to the original state and pulling it up.
