Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a side view showing an embodiment of the agricultural column extractor according to the present invention, FIG. 2 is a side view showing a column extraction state by the agricultural column extractor of FIG. 1, and FIG. 3 is a fulcrum receiving member and a lever member. FIG. 4 is a perspective view of the main part in a state where the lever member and the locking member are engaged, and FIG. 5 is a cross-sectional view of the state in which the column is erected by the cylindrical member of the lever member. FIG. 6 is a cross-sectional view showing a state in which the column head is driven by the cylindrical member, FIG. 7 is a perspective view showing a state in which the lifting member is interposed between the lever member and the locking member, and FIG. FIG. 9 is a perspective view of another embodiment of the agricultural column extractor of the present invention, and FIG. 10 is a perspective view of another embodiment of the present invention. FIG. 11 is a perspective view showing another embodiment of the present invention.

  As shown in FIG. 1 and defined as the invention of claim 1, the agricultural column extractor 10 of the present invention is a fulcrum receiving portion disposed on the side of the agricultural column S having a locking portion 11. The fulcrum receiving member 20 having the fulcrum 21 and the fulcrum part 31 supported by the fulcrum receiving part 21 of the fulcrum receiving member 20 and having the engaging part 32 engaged with the locking part 11 of the support column S at the tip part. The lever member 30 is configured. The fulcrum part 31 of the lever member 30 supported by the fulcrum receiving part 21 of the fulcrum receiving member 20 is a fulcrum point of the lever principle, the rear part 39 of the lever member 30 is a force point, and the engaging part 32 is an action point. As shown in FIG. 2, when the rear portion 39 of the lever member 30 that is a power point is pushed downward, a force is generated in a direction in which the locking portion 11 is pushed upward in the engaging portion 32 that is the operating point. 11 can be lifted and removed from the ground G.

  As defined in the invention of claim 2 and as shown in the figure, the locking portion 11 is formed by fixing a locking member 12 having a locking projection 13 to a column S, and the locking projection 11 The support column S is lifted through the portion 13. As a method of fixing the locking member 12 to the column S, for example, a wood screw or the like can be used. Moreover, since the support | pillar S is often used repeatedly many times, once it adheres, it can be done any number of times after that, and a labor can be saved.

  Further, as defined and illustrated as the invention of claim 3, the fulcrum receiving member 20 has a rod-like main body portion 22 and a structure having an insertion portion 25 and a fixing plate portion 26 at the bottom, A simpler and more stable sampling operation can be performed. That is, when the support S is pulled out from the ground G, if the rear end portion of the lever member 30 is pushed down, a downward force is applied to the fulcrum receiving portion 21 and the fulcrum receiving member 20 becomes unstable. This configuration can prevent this. At this time, by inserting the insertion portion 25 into the ground G and stepping on the fixing plate portion 26 with the foot, the fulcrum receiving member 20 can be easily fixed without applying force.

  As shown in FIG. 3, in this embodiment, the projecting fulcrum portions 31, 31 projecting on both sides of the lever member 30 are provided with hook-shaped fulcrum supports provided on both sides of the U-shape viewed from the front. The parts 21 and 21 are supported and supported. The hook-shaped fulcrum receiving portion 21 is substantially G-shaped in a side view and is configured such that the fulcrum portion 31 is not easily detached even if the lever member 30 is moved.

  Further, as shown in FIG. 3, in this embodiment, as defined in the invention of claim 5, the engaging portion 32 of the lever member 30 is formed by the bifurcated portion 33, and can be locked with a simple configuration. The member 12 can be engaged. FIG. 4 is a view showing a state in which the engaging portion 32 of the lever member 30 is engaged with the engaging protrusion 13 of the engaging member 12. The engaging portion 32 formed by the bifurcated portion 33 is a strut S. Are engaged so as to sandwich the locking protrusions 13 and 13 on both sides of the locking member 12.

  5 and 6 show a state in which the support upper end SU is driven when the support S is erected. That is, in this embodiment, as defined in the invention of claim 6, the lever member 30 is composed of a cylindrical member 37 having an opening 38 at the rear end portion 39, and the column upper end SU when the column S is erected. Is configured to be driven. As shown in the drawing, a lever member 30 made of a cylindrical member 37 is inserted into the upper portion of the support column S through the opening 38, and the lever member 30 is moved up and down to strike the upper end SU of the support column S, thereby applying a large force. It is possible to stand upright simply by driving the support S into the ground. In this case, in order to drive the support column S without damaging it, it is preferable to attach a metal cap member 40 or the like to the upper end SU of the support column S.

  Next, FIG. 7 will be described. In this example, the lifting member 50 interposed between the engaging portion 11 and the engaging portion 32 of the lever member 30 is defined as defined in the invention of claim 8. In addition. By interposing this lifting member 50 when the drawing height does not match in the case of a relatively long column S or the height of the engaging portion 11 and the engaging portion 32 of the fulcrum receiving member 20, The column S can be easily extracted. Reference numeral 51 for the lifting member 50 in FIG. 7 is a lifting main body portion, 52 is a lifting main body upper engaging portion that engages with the locking portion 11 of the column S, and 53 is engaged with the engaging portion 32 of the lever member 30. The lifting main body lower engaging part 54, 54 represents a handle part.

  Still another embodiment will be described. In the embodiment shown in FIG. 8, the lever member 70 has a rod-shaped main body portion 75 and the fulcrum portion 71 is formed at an arbitrary position of the rod-shaped main body portion 75 as defined in the invention of claim 7. It is configured. According to the lever member 70 of this example, the distance between the fulcrum and the action point can be arbitrarily changed, and thereby the struts S having various lengths or weights can be extracted with a simple configuration. Reference numeral 72 denotes an engaging portion. Further, the fulcrum receiving portion 81 of the fulcrum receiving member 80 of FIG. 8 is formed in a circular shape in which the rod-like main body portion 75 of the lever member 70 can be inserted and held at the upper end of the rod-like main body portion 82. Reference numeral 85 denotes an insertion portion, and 86 denotes a fixed plate portion, which is the same as described in the previous embodiment.

  9 to 11 show a structure in which the fulcrum receiving member has a plurality of fulcrum receiving portions as defined in the invention of claim 4. The fulcrum receiving member 90 shown in FIG. 9 is formed by forming two circular fulcrum receiving portions 91 and 92 at the tip and middle of the rod-shaped main body 93. Reference numeral 95 is an insertion portion, 96 is a fixed plate portion, and 70 is a lever member described in the previous embodiment. By having the plurality of fulcrum receiving portions 91 and 92, the adaptability to the position of the column S and the locking unit 11 is increased, and the column S can be easily extracted.

  The fulcrum receiving member 100 shown in FIG. 10 is formed by forming three protrusion-shaped fulcrum receiving portions 101A, 101B, and 101C on a rod-like main body portion 103. Reference numeral 105 denotes an insertion part, 106 denotes a fixed plate part, 110 denotes a lever member, 101 denotes a fulcrum part, and 102 denotes an engaging part. Similarly, the fulcrum receiving member 120 of FIG. 11 is formed by forming three fulcrum receiving portions 121A, 121B, and 121C in a ladder shape between two rod-shaped main body portions 123. Reference numeral 125 denotes an insertion part, 126 denotes a fixed plate part, and 110 denotes the lever member.
