Utility Model Registration No. 3100860 Japanese Unexamined Patent Publication No. 2016-21975

By the way, the grass collecting work with the conventional grass collecting tool is performed on the slope 26 (for example, the bank) between the private house 25 and the paved road 27 as shown in FIGS. 8 (a) and 8 (b) (Fig.). 8 (a) a indicates the weeding range), when collecting grass after weeding with human power or a hammer knife, as shown in FIG. 9, the heavy machine 14 is installed on the paved road 27 and at the tip of the boom of the heavy machine 14. Attach the grass collecting tool, move the grass collecting tool in the direction of arrow F (front direction), and once collect the cut grass in the longitudinal direction of the slope 26 (see grass 28a), as shown in FIG. Further, by moving the boom in the direction of arrow G (horizontal direction), the grass is collected in one place on the slope 26 (see the figure (b) or grass 28b), or manually (same). In Fig. (C), b is the range of movement of people), and it was collected at two places on the slope 26 (see grass 28c and 28d).

In any case, the grass finally collected must be collected on the slope 26 as shown in the grasses 28b, 28c, 28d of FIGS. 8 (c) and 8 (d). After that, in the loading work on the truck or the like, the grass 28b to 28d collected on the slope 26 is further manually transferred from the slope 26 to the paved road 27, and then the truck or the like is put on the paved road 27. I was going to load it in.

This is because the comb teeth of the conventional grass collecting tool are made of a hard material such as a metal rod, so that the grass collecting work on the slope 26 such as a bank is possible, but the conventional grass collecting tool can be used. If the grass cut on the upper surface of the paved road 27 is collected by using the grass, the metal rod of the grass collecting tool will damage the pavement surface, so that the cut grass cannot be moved onto the paved road 27. rice field.

Hereinafter, the grass collecting plate 1 according to the present invention will be described in detail. First, the configuration of the grass collecting plate 1 on the front surface side will be described.

As shown in FIGS. 1 and 3A, first, a horizontally long metal plate 2 as a substrate is provided, and fastening holes 3 for bolts and nuts are provided in the lateral direction along the lower edge 2a of the horizontally long metal plate 2. 18 places are formed through. The front surface of the horizontally long metal plate 2 is designated as 2b, and the back surface thereof is designated as 2c. The left and right right-angled corners of the upper part are excised for weight reduction and the like, and excised portions 2d and 2d are formed. The horizontally long metal plate 2 is, for example, an iron plate having a width of 1800 mm, a length of 250 mm, and a thickness of 6 mm to 10 mm. Further, the portion (front and back) where the fastening hole 3 is formed along the lower edge 2a is referred to as a metal plate fixing portion.

In FIG. 1, the front surface 2b side of the horizontally long metal plate 2 is defined as the “front side”, and the back surface 2c of the horizontally long metal plate 2 is defined as the “back side”. In addition, the left and right are defined as "left and right direction" and the top and bottom are defined as "up and down direction" toward the paper. Further, the front surface 2b side of the horizontally long metal plate 2 is also referred to as "front", and the back surface 2c side is also referred to as "rear". Further, as shown in FIG. 4, the grass collecting plate 1 of the present invention has a front-back symmetric structure (front-back symmetric structure) in which the front and back sides are symmetrical with respect to the horizontally long metal plate 2. On the premise of this, first, the surface side of the horizontally long metal plate 2 will be described (see FIG. 5).

The resin horizontally elongated elastic plate 4 is superposed on the lower edge 2a (metal plate fixing portion) on the surface 2b side of the horizontally elongated metal plate 2 by aligning the fastening holes 3 and the fastening holes 7 (FIGS. 1 and 3 (c). )reference). In this resin horizontally long elastic plate 4, a plurality of notch grooves 5 are formed along the lower edge, so that a plurality of grass collecting pieces 6 having a predetermined width t (widths on both sides are t / 2) are formed on the lower edge. It is formed adjacent to each other, and as shown in FIG. 3C, 18 fastening holes 7 for bolts and nuts are formed through the upper edge 4a in the lateral direction. The horizontally long elastic plate 4 made of synthetic resin is a rubber plate having a width of 1800 mm, a length of 200 mm, and a thickness of 5 mm, and has elasticity to bend in the arrow A direction (arrow B direction) (that is, the direction along the short side direction) in FIG. It is a thing. The area where the fastening hole 7 is formed along the upper edge 4a is referred to as an elastic plate fixing portion.

In the present embodiment, another horizontally long elastic plate 4 made of the same synthetic resin is superposed on the surface 4b side of the horizontally long elastic plate 4 made of resin. That is, two horizontally long elastic plates 4 made of synthetic resin are stacked and used (see FIGS. 4 and 5). In this case, the positions of the fastening holes 7 are aligned in the front-rear direction with respect to the two synthetic resin horizontally elongated elastic plates 4 and 4, and further aligned with the fastening holes 3 of the horizontally elongated metal plate 2 in the front-rear direction.

Further, when the fastening hole 3 of the horizontally long metal plate 2 and the fastening hole 7 of the resin horizontally long elastic plate 4 are aligned, the lower edge 2a of the horizontally long metal plate 2 and the upper end 5a of the notch groove 5 are aligned. The interval between and is configured so that a predetermined interval T is formed (see FIG. 1). This is to secure a space T on the plate surface for the resin horizontally elongated elastic plate 4 to be elastically curved in the direction of arrow A (or the direction of arrow B) and to be restored by the elastic repulsive force (FIG. 4). reference).

The reason why the two resin horizontally long elastic plates 4 and 4 are overlapped is to adjust the elastic force. For example, a rubber plate having a thickness of 5 mm may have a weak elasticity (elastic repulsive force), so that the elasticity (elasticity) is stronger. This is to obtain (repulsive force) (see FIG. 4).

Next, the fastening hole 7 and the fastening hole 9 are aligned with the surface 4b of the resin horizontally elongated elastic plate 4, and the resin horizontally elongated reinforcing elastic plate (first resin horizontally elongated reinforcing elastic plate) 8 (FIG. 3 (d)).

The thicknesses of the plates 4, 8 and 10 overlap (5 mm x 4 = 20 mm), while the lower end side is made of resin elastic plates 4, 4, resin horizontally elongated reinforcing elastic plates 8, and resin horizontally elongated reinforcing elastic plates 10. As the thickness gradually decreases in the order of, the thickness becomes thinner as 20 mm, 15 mm, and 10 mm toward the tip, and as a result, in the direction of arrow A or as compared with the case of one resin elastic plate 4. The elastic force and elastic recovery force in the direction of arrow B are strengthened, and the elastic force is not easily curved in the direction of arrow A. It is configured to elastically return in the direction of arrow A.

It depends on the properties), whether the surface to be collected is a paved surface or soil, etc., and how much the elastic strength of the entire grass collecting plate is set, etc., so it is optional.

In the case of the present invention, when the grass to be collected is weeded with a hammer knife and is fine, the elastic strength does not have to be high. Therefore, for example, as in the fourth to sixth embodiments, the horizontally elongated metal A resin horizontally long elastic plate 4 or the like may be provided only on the front side (front side) of the plate 2, or when the grass to be collected is manually weeded and there are many relatively long grasses, the grass collecting plate 1 is used. Since it is better that the elastic strength is high, for example, as in the first to third embodiments, it is preferable to provide a resin horizontally elongated elastic body 4 or the like in front of and behind the horizontally elongated metal plate 2.

Further, when the surface to be collected is a paved surface, for example, it is possible even if the elastic strength is relatively low. In the case of, the higher the elastic strength, the easier the work, so that the ones of the first to third embodiments may be used.

Whether or not to provide the resin horizontally long reinforcing elastic plate 8 or 10 is also optional, and can be determined depending on the condition of the working surface, the properties of the weeded grass, and the like. Further, it is optional whether or not the short metal rod 21 (comb blade 21') is provided on the elongated metal plate 13, and it is not necessary to provide the short metal rod 21 (comb blade 21').

When the resin horizontally elongated elastic plate 4 or the like is provided only on the front side or the rear side of the horizontally elongated metal plate 2, the boom 15 is moved in the direction of arrow C to collect grass, and the boom 15 is moved in the direction of arrow D. It is considered that the elasticity and elastic recovery force of the grass collecting plate 1 are slightly different from those in the case of collecting grass.

On the other hand, when the horizontally long elastic plate 4 or the like made of resin is provided in a symmetrical structure in the front-rear direction of the horizontally long metal plate 2, the boom 15 is moved in the direction of arrow C to collect grass, and the boom 15 is moved in the direction of arrow D. Since the elasticity and the elastic recovery force of the grass collecting plate 1 are substantially the same and the operability is the same as in the case of collecting grass, good operability can be obtained. The resin horizontally long elastic plate 4 may be provided with one, two or a plurality of sheets depending on the properties of the grass to be collected.

Further, the elasticity and elastic recovery force of the grass collecting plate can be adjusted by gradually shortening the lower edge of the overlapping reinforcing elastic plates by the resin horizontally elongated reinforcing elastic plate 8 and the resin horizontally elongated reinforcing elastic plate 10. can. Further, an example was shown in which the bolt B was inserted into the fastening hole from the front surface side of the grass collecting plate 1 and the nut N was fastened on the back surface side. A configuration in which the nut N is fastened may be used.

In the following operation description, as shown in FIGS. 4 and 5, two resin horizontally elongated elastic plates 4, a resin horizontally elongated reinforcing elastic plate 8 and a resin horizontally elongated reinforcing elastic plate 10 are provided around the horizontally elongated metal plate 2. A comb-edged short metal rod 21 is fixed to the surface of the elongated metal plate 13 which is used, and is symmetrically configured in the front-rear direction with the horizontally elongated metal plate 2 as the center (FIGS. 1, FIG. 4, and FIG. 5). , The one shown in FIG. 6) will be described.

First, as shown in FIG. 7, a case where weeds on the slope 26 (bank) facing the private house 25 are weeded by human power or a hammer knife and then weeded using the weeding board 1 according to the present invention will be described. do. It is assumed that the grass collecting plate 1 is gripped by the claw 20 at the tip of the boom 15 of the heavy machine 14 (see FIG. 6). Specifically, for example, as shown in FIG. 6, the lower surfaces of the ridges 18 and 18 provided on the front and back sides of the horizontally long metal plate 2 of the grass collecting plate 1 are gripped from the front and back by the pair of claws 20. , The grass collecting plate 1 is gripped by the claw 20. The place to be gripped by the claw 20 may be the portion of the ridge 17 of the metal plate 16 to be gripped.

Next, as shown in FIG. 6, the heavy machine 14 is stopped on the paved road 27, the boom 15 is extended toward the slope 26 side, and the claw 20 is moved from the arrow C direction to the arrow D direction to remove the weeded grass. Move it onto the paved road 27.

At this time, the movement of the boom 15 is in the direction of arrow D in FIG. 7 (c), and the grass collecting plate 1 can continuously move from the slope 26 to the paved road 27. As a result, grass can be collected on the paved road 27 (see FIG. 7 (c) grass 28a').

When the boom 15 is moved in the direction of arrow D, the boom 15 is moved in the direction of arrow D with the grass piece 6 of the resin horizontally elongated elastic plate 4 in contact with the slope 26. In that case, , Centering on the horizontally long metal plate 2, the front and rear resin horizontally long elastic plates 4 and 4 have elastic forces reinforced by the front and rear resin horizontally long reinforcing elastic plates 8 and 8 and the resin horizontally long reinforcing elastic plates 10 and 10. Therefore, while elastically deforming in the direction of arrow A, weeds can be efficiently collected within the width range of the resin horizontally elongated elastic plate 4. Further, in the final stage of grass collection, the boom 15 is lifted upward to separate the grass collecting plate 1 from the paved road 27. At this time, the resin horizontally elongated elastic plates 4 and the resin horizontally elongated reinforcing elastic plates 8 and 10 are separated. Due to the elastic recovery force of, the resin horizontally elongated elastic plates 4 and the resin horizontally elongated reinforcing elastic plates 8 and 10 can be elastically restored to a straight state from the state of being curved in the direction of arrow A. In this way, the grass collecting plate 1 (horizontally elongated elastic plate 4, resin horizontally elongated reinforcing elastic plate 8, 10) is elastically curved and returned to a straight state by an elastic restoring force, thereby increasing efficiency. Can be collected as a target.

Further, in the grass collecting plate 1 of the present invention, since the resin horizontally elongated elastic plates 4 and the resin horizontally elongated reinforcing elastic plates 8 and 10 are made of resin, the surface of the slope 26 is the soil surface, and the paved road 27 is formed. Even on the paved surface, the grass collecting plate 1 can be continuously moved from the slope 26 to the paved surface 27a in the direction of arrow D, and the grass collecting work can be performed very efficiently. Moreover, since the grass collecting plate 1 is made of rubber and a plurality of rubber collecting pieces 6 are formed, even if the plurality of grass collecting pieces 6 and the pavement surface 27a come into contact with each other on the pavement surface 27a, the pavement surface 27a has the effect of not being scratched.

Moreover, since a plurality of cut grooves 5 are formed and a plurality of grass collecting pieces 6 are formed on the lower edge of the resin horizontally elongated elastic plate 4, the weeded grass is placed along the cut groove 5. It can be aligned to some extent and has the effect of making it easier for the collected grass to come together.

Further, the grass collecting plate 1 of the present invention has a plurality of short metal rods 21 on the elongated metal plate 13, and the lower half portion of these short metal rods 21 protrudes downward from the elongated metal plate 13 as a whole. Since the comb blade 21'is formed as, the grass is aligned to some extent by the comb blade 21'while moving the grass collecting plate 1 in the direction of arrow D, and the grass is collected on the pavement surface 27a ( When the grass 28a') is used, the direction of the grass can be matched to some extent, and when the grass is finally loaded on a truck or the like, there is an effect that it is easy to be organized.

As shown in FIG. 7 (c), after collecting as grass 28a'on the pavement surface 27a, as shown in FIG. 7 (d), the boom 15 is moved in the direction of arrow E to grow grass on the pavement surface 27a. It can be summarized as 28b'(see FIGS. 7 (a) and 7 (b)) or grass 28c' (see FIG. 7 (d)).

After that, a truck may be driven onto the paved road 27, and the grass 29b'or the grass 28c' may be loaded onto the truck. In this case, since the grass exists on the paved road 27, the truck can be brought close to the position close to the grass, and the work of loading the grass onto the truck can be efficiently performed.

Even when the slope 26 is reinforced by a block or the like, the grass collecting plate 1 according to the present invention can be used without any problem because the block or the like is not damaged. That is, since the grass collecting plate 1 is made of rubber and a plurality of rubber collecting pieces 6 are formed, even if the plurality of grass collecting pieces 6 come into contact with the block on the block surface, the block surface is scratched. There is an effect that is not attached.

That is, since at least the resin horizontally long elastic plate 4 is used, grass can be continuously collected from the slope 26 to the paved road 27, and the paved surface 27a and the blocked slope are not damaged. It can be used for weed collection work without any problem.

According to the grass collecting plate for heavy machinery according to the present invention, as described above, for example, the claw 20 of the heavy machinery 14 grips the metal plate 16 to be gripped by the grass collecting plate 1 and the boom 15 is moved back and forth (grass collecting). By moving the plate 1 in a direction orthogonal to the left-right direction), weeded grass such as a slope can be easily collected. At this time, the resin horizontally elongated elastic plate 4 or the like is curved to be elastic. The grass can be easily collected by using force, and since the grass piece 6 is made of elastic resin, the grass can be continuously collected from the bank to the pavement surface, and the pavement surface and the concrete block can be collected. Etc. will not be hurt.

Further, by superimposing the first or second resin horizontally elongated reinforcing elastic plates 8 and 10 on the resin horizontally elongated elastic plate 4, the grass collecting plate 1 is subjected to the condition of the surface for collecting grass, the properties of the weeded grass, and the like.

Further, since the resin horizontally elongated elastic plate 4 and the like can be arranged symmetrically on the front and back of the horizontally elongated metal plate 2, the elastic force of the weed collecting plate 1 depends on the condition of the surface for collecting grass, the properties of the weeded grass, and the like. And the elastic recovery force can be further strengthened or adjusted.

Further, by arranging the resin horizontally long elastic plates 4 and the like symmetrically on the front and back of the horizontally long metal plate 2, for example, when the grass collecting plate 1 is gripped by the claws 20 of the heavy machine 14 and the boom 15 is moved forward. The operability can be improved by making the operation feeling of the grass collecting plate 1 the same as when moving it to the rear side.

Further, a resin horizontally elongated elastic plate 4 or the like can be sandwiched and fixed between the front and back elongated metal plates 13 and the elongated metal plate 13, and the resin horizontally elongated elastic plate 4 or the like can be firmly fixed to the horizontally elongated metal plate 2. can do.

Further, by the action of the comb blade 21', the collected grass can be aligned to some extent, and for example, the loading work on the truck after the weeding can be efficiently performed.

Although the embodiment in which two resin horizontal elastic plates 4 are stacked is described in FIG. 4, one resin horizontal elastic plate 4 may be used or three or more resin horizontal elastic plates 4 may be stacked depending on the condition of the weeded grass. Is also good. Further, although the elastic plate is made of resin and is made of a rubber plate, it is a concept that the resin includes both natural resin and synthetic resin as long as it is an elastic plate.

According to the grass collecting board used in, for example, a heavy machine according to the present invention, the grass collecting work can be continuously performed from the bank or the like to the pavement surface, and the pavement surface is not damaged, so that it is widely used as a grass collecting board.
