Description

  The present invention relates to a weed tree remover that can easily remove roots of small trees and the like by adjusting the distance between the left and right blades, not limited to garden and field weeds.

  All of the weeding tools shown in the gazettes of Patent Documents 1 to 7 were used for the purpose of removing small weeds growing in the garden in the garden, so weeds and small trees with deep roots were removed. For this reason, anything that aims at removing weeds in small gardens is not practical enough.

  However, when weeding in a slightly large field or a large farm garden that is not surrounded by fences, weed trees have relatively deep roots, and weeding tools are durable even when applied with a little weight. It is desired that a tool with a cutting edge that is easy to perform removal work at a deep root can be used to reduce physical strength and improve work efficiency. For this purpose, the conventional weeding tools have the disadvantage that the cutting edge enters under the roots of large and small weed trees and cannot be removed.

  In applications where weeding is generally carried out in large fields or large farm gardens that are not surrounded by bushes, this drawback is a major obstacle for removing weed trees. Specifically, the work of removing deep roots of weed trees consumes physical strength, and the brackets of the weeding tools bend against the roots that are deeply embedded in hard soil, or the tips of large weeds are not covered only with the hand. There have been problems such as efficient and time-consuming work.

As an improvement measure, there is a method of applying high voltage to remove weeds and disinfecting surrounding soil as shown in Patent Document 8. The apparatus disclosed in Patent Document 8 is not practical for work in a general place as described in the previous section because the apparatus becomes larger and the operation thereof becomes complicated.

  The problem to be solved is that the removal tool cannot be inserted into the root of the weed tree that becomes a hindrance in the operation of manually removing the weed tree having deep roots in the soil, so that the work efficiency is poor and fatigue is caused. The distance between the left and right blades is adjusted with a plate having bolt holes that connect the left and right blades so that the distance between them can be adjusted, and the blades are inserted into the soil where weeds are growing to remove the weeds.

  In order to remove the roots of weed trees, the present invention removes the roots while suppressing exhaustion by inserting two blade tips into the soil and allowing them to be adjusted according to the size of the roots. Doing is the main feature.

  In order to adjust the distance between the left and right blades to be inserted into the soil according to the roots of the weeds, the weed tree remover of the present invention connects the left and right blades to be inserted into the soil with a plate with an adjustment hole. Since the distance between the blades can be adjusted according to the depth and size, there is an advantage of removing the roots of large and small weed trees.

  The left and right blades are connected by a plate with adjustable holes that can adjust the distance between the left and right blades, and the distance between the left and right blades can be adjusted. In the weed tree removing means, a plate provided with a bolt hole at the base of the blade, mounted on the upper part of the bolt hole of the blade, and an adjustment hole set so that the left and right blades have an appropriate interval, and a blade, The fastening bolt that presses the plate is provided with a butterfly screw, and a handle mounting part that is slightly upward with respect to the horizontal plane is provided at the base of both blades. We realized a weed tree remover characterized by its removal.

The weed tree is inserted into the soil where the weed tree grows so that the weed tree can be removed. In this weed tree removing means, adjustment holes 3a, 3b, 3c provided with a bolt hole at the base of the blade 1, mounted on the upper part of the bolt hole of the blade, and set so that the left and right blades 1 are spaced from each other. Since the plate includes the blade, the fastening bolt 4 that presses the plate, and the butterfly screw 5 that presses the plate 2 from above, the fastening bolt 4 is replaced with another adjustment hole of the plate and the thumbscrew 5 is tightened. Thus, it can be used according to the size of the root by changing the left-right distance between the two blades depending on the size of the underground root. The double-edged blade 1 is made of iron and is hardened to be strong and tenacious, and the blade is thick and has a slightly sharp slope on the side surface. A handle attachment portion 12 is provided at the root portion 9 of the double-edged blade, and left and right handles 7 are connected to this to remove weeds with the double-edged blade 1 having the handle. The handle may be either wooden or aluminum.

The left and right blades 1 are connected to each other by a plate 2 having an adjustment hole that can freely adjust the interval so that the interval can be adjusted. As shown in the plan views (FIGS. 1 to 3), the plate 2 has adjustment holes 3 a, 3 b, 3 c in three stages.
The plate 2 is overlaid on one blade 1 and a fastening bolt is inserted into the bolt hole 3d. A washer is inserted into this bolt, and a thumbscrew is tightened to press and fix the end of the plate 2 to the root portion of the blade 1. To do.
In order to fix the other blade to the plate, the fastening bolt 4 inserted into the blade and the plate adjusting holes 3a, 3b, 3c is inserted into one of the plate adjusting holes, the washer 6 is inserted, and the thumbscrew 5 is inserted. Fasten and connect the blade with the plate 2. And when changing the space | interval of both blades, the fastening bolt 4 is replaced by the adjustment hole opened in the other three steps, the washer 6 is put, and the thumbscrew 5 is tightened. In this way, the distance between the two blades can be changed according to the size of the underground root.
