Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hoe used for agricultural work and weeding.

[0002]

[Prior art]

 As shown in FIG. 3, a general hoe used for farming work includes a plate-shaped metal fitting having a blade called a head 21 and a long wooden handle 26, and a wooden or metal holding member. 25, it is formed so as not to be detached. When using the hoe described above, the handle is grasped with both hands with the tip of the nose facing the user, and then the hoe is swung up to take advantage of the gravity caused by the weight of the nose. The hoe is used to drop the hoe down to the ground and strike the tip of the hoe against the ground or comb with a blade.

[0003]

[Problems to be solved by the invention]

 However, the above-mentioned head is generally heavy because it is formed by molding a thick iron plate with a blade, and when a hoe equipped with the head is used by a woman, a child, or an elderly person, the weight is reduced by the weight. , It was very burdensome to raise the hoe. However, when the hoe is lowered, the gravitational force applied to the weight of the hoe is used.Therefore, it is not possible to reduce the weight of the hoe because the usability of the hoe is deteriorated. When using, there was a problem that fatigue due to the work was significantly increased due to the weight of the previous work, resulting in a decrease in work efficiency.

[0004] Further, most of the causes of the loss of service life of the hoe are that the cutting edge is rusted or damaged. However, in many hoes, the head and the holding member are firmly fitted, and it is difficult to remove only the head from the hoe, so that the hoe is usually replaced with a new hoe without repair. I was For this reason, although the handle and the holding member are sufficiently durable, the above-mentioned hoe has to be discarded, which is very wasteful.

According to the present invention, by skillfully reducing the weight of the hoe, women, children, and the elderly can work without any trouble, and it is also possible to easily and reliably replace the durable nose due to damage or the like. The aim is to provide a lean hoe.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, according to the invention of claim 1, a hoe formed by supporting and fixing a plate-shaped tip having a blade portion on the distal end side and a long handle with a holding member. The tip is divided into a blade plate on the distal end side and a support plate on the base end side, and the blade plate and the support plate are fixed by fixing means, and the thickness of the blade plate is larger than that of the support plate. Is characterized by being formed thinly.

Here, the front end side and the base end side are referred to as the base end side, which is the side supported and fixed by the holding member, while the side provided with the blade portion is referred to as the front end side. Further, the fixing means may be any as long as it can fix the blade plate and the support plate so that they cannot be detached, and specific examples thereof include caulking with a rivet, welding, and the like.

With this configuration, the weight of the hoe can be reduced because the thickness of the blade plate is reduced, and the support plate is formed to be thicker than the blade plate. However, since the centrifugal force due to the weight of the support plate is added when the hoe is lowered, the hoe can be used without difficulty.

The fixing means may be formed so as not to be detached, but the support plate 3 and the blade plate 2 may be formed so as to be detachable. When formed in this way, if the blade plate formed thinner than the support plate is damaged by use, it can be easily replaced with a new blade plate, and the relative service life of the hoe can be extended. Because it is possible, it is also excellent from an economic viewpoint.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of a hoe according to the present invention will be described with reference to FIGS. 1 and 2. The hoe of the present invention is a hoe 1 in which a thick support plate 3 formed in a plate shape and a blade plate 2 formed thinner than the support plate 3 are integrally fixed by rivets 4. A cylindrical holding member 5 having one end fixed to the support plate 3 and having a fitting portion 14 at the other end, and a long handle inserted and fixed to the fitting portion 14 of the holding member 5. 6 and is formed therefrom.

[0011] The head 1 is a flat plate-shaped metal fitting serving as an action part of the hoe. The head 1 of the present invention is a blade plate 2 having a blade portion 13 on the front end side and a support plate 3 on the base end side. The blade plate 2 and the support plate 3 are caulked with rivets 4 and connected and fixed again integrally. The blade plate 2 is formed of a thin, high-hardness steel or the like having a wall thickness of about 0.8 mm to 2.0 mm, and is formed to be thinner along the outer edge of the blade plate 2. Provided blade portion 13. On the other hand, the material of the support plate 3 is not limited as long as it is a metal. However, in order to maintain a certain weight, the support plate 3 is formed to have a thickness in the range of about 2.5 mm to 3.0 mm so as to be thicker than the blade plate 2. ing. This is because the hoe is lowered using the gravity applied to the weight of the head 1, so that the weight required for applying the gravity only needs to be provided on the support plate 3, and the blade plate 2 Even if the weight is reduced, there is no inconvenience in the usability of the hoe.

Further, a plurality of through holes 7 and through holes 8 respectively penetrating in the thickness direction are provided at the base end of the blade plate 2 and the end of the support plate 3 at the distal end thereof at intervals. The rivet 4 is inserted into the overlapped through-hole 7 and the through-hole 8, and the rivet 4 is caulked. Further, by welding the overlapping portions, the blade plate 2 and the support plate 3 are fixed so as not to be detached.

The holding member 5 is a cylindrical connection fitting for fixing the support plate 3 of the head 1 and one end of the handle 6 so as not to be detached. A hole-shaped fitting portion 14 for holding one end of the handle 6 is provided on one end side of the holding member 5 in the cylinder direction, and a ring that slides along an outer peripheral surface of a peripheral wall 17 of the holding member 5. When the fastening member 16 is pulled up along the peripheral wall 17, the handle 6 held by the fitting portion 14 is fastened undetachably from the outside. On the other hand, on the other end side of the holding member 5 in the cylindrical direction, a projecting piece 15 projecting outward from the peripheral wall 17 of the holding member 5 is provided over the entire circumference. When the plate 3 is superimposed, a plurality of fixing holes 10 and fixing holes 11 penetrating in the thickness direction in a state where they coincide with each other are provided at intervals. The overhanging piece 15 and the support plate 3 are overlapped in a state where the fixing holes 10 and the fixing holes 11 are aligned, and the fixing rivets 9 are inserted into the matching fixing holes 10 and the fixing holes 11 and swaged. The holding member 5 and the support plate 3 are fixed so as not to be detached.

The handle 6 is a long wooden bar, and the cross-sectional shape of the handle 6 is formed in a rounded state so that a user can easily hold it. Further, when one end in the longitudinal direction of the handle 6 is inserted into the fitting portion 14 of the holding member 5, the handle 6 and the holding member 5 are fixed so as not to be detachable by the above-described fastener 16 described above. It is not limited to a fixed one. For example, as shown in FIG. 2, a bolt 27 that penetrates laterally toward the peripheral wall 17 is screwed into the holding member 5 in which the handle 6 is inserted into the fitting portion 14, and is further fastened by a nut 28 to hold the holding member 5 Alternatively, the handle 6 may be fixed.

The bolt shown in FIG. 2 is inserted into the through hole 7 and the through hole 8 provided in the blade plate 2 and the support plate 3 of the hoe shown in FIG. It is to be concluded. This is because the blade plate 2 can be detached from the support plate 3 by unfastening the bolts 4a and the nuts 12, so that the blade plate 2 is rusted or broken and the durability in work is lost. However, if only the blade plate 2 is replaced, the existing hoe can be used again without discarding the holding member 5 and the handle 6.

[0016]

[Effect of the invention]

 According to the first aspect of the present invention, the blade plate is made thinner than the support plate, so that the entire hoe is lightened and the hoe descends with a light force when swung up. As the hoe is raised, no special force is applied when lowering or lowering the hoe due to the weight of the support plate. Therefore, it is very easy to raise and lower the hoe, and the work can be performed smoothly and efficiently. .

According to the present invention, since the blade plate forming the cutting is formed detachably from the support plate, the blade plate is removed even if the blade plate loses its durability. This makes it possible to replace the existing holding member and handle with waste, and to provide an economically suitable hoe without wastefully discarding the existing holding member and handle.
