Description

The present invention relates to an apparatus for cutting grass on a ridge slope or performing a treatment for hindering the growth of grass.

Conventionally, there are the following proposals for treating grass on ridge slopes.
FIG. 8 is a diagram showing a defect example of the conventional ridge slope grass treatment device. In 8-A
When processing grass on a ridge slope such as mowing, the traveling machine 810 on the ridge is connected to the grass processing device 830 on the ridge via a guide rod 820, but since the grass processing device 830 is applied, it may be necessary. The traveling machine 810 is pulled below the ridge and falls, and if the worker is pulling, there is a risk that the worker will also fall. In particular, when the traveling machine body 810 is small and lightweight, the risk is high. Making a large weight increases the equipment price and is difficult to adopt.
In 8-B, the risk of tipping is prevented by balancing the torque due to the weight of the grass treatment device 830 on the ridge slope side and the torque due to the weight of the first weight 840 attached to the opposite side. Since the first weight 840 and the lowering rod occupy the space, there is an inconvenience that it gets in the way.

FIG. 9 is a diagram showing a conventional grass treatment, particularly a grass cutting device.
9-A is described in Patent Document 1. As a similar one, there is Patent Document 2.
Workers on the top of the ridge support a mower that moves on the slope of the ridge. This can be dangerous to the operator, as the mower may tip over or be dragged by the mower's movement, especially when turning.
9-B is as shown in Patent Document 3. The difference from Patent Document 1 and Patent Document 2 is that there is a moving body that can move the upper surface of the ridge in the longitudinal direction of the road on the upper surface, and there is a means for cutting the grass of the ridge by connecting to the moving body. Again, the weight of the mower is transmitted to the operator through the moving object, which poses a danger. 9-C is a proposal having the characteristics of the former two, and is shown in Patent Document 4. There is a moving body that can move the upper surface of the ridge in the longitudinal direction of the road on the upper surface, and a self-propelled mower can work on the slope of the ridge by connecting it with a wire. Again, because the moving object is being pulled by the mower, there is a risk that the moving object will tip over and the operator will be at risk.
Reference numeral 9-D is shown in Patent Document 5, in which a mower is attached to the arm of the tractor. Since the tractor is heavy, it is not dragged by the mower and is less dangerous. However, there is an inconvenience that the overall equipment price becomes high and it is difficult to introduce it.
9-E is shown in Patent Document 6, but Patent Document 7 is similar. A mowing device is attached to the elevating link mechanism located in front of or behind the traveling machine. This also has the advantage that the traveling machine has the stability of heavy objects over the mowing device, but it also has the disadvantage that the overall device price is high and it is difficult to introduce it.

FIG. 10 is a diagram showing a conventional grass treatment, particularly a grass cutting device.
Reference numeral 10-A is shown in Patent Document 8. Since the wheels of the traveling body are along the rails, the charging device of the traveling body and the external charging means are aligned. Since the rails regulate alignment and running, if this is weighted by a mower on a ridge, the wheels may lift and tip over and derail.
Reference numeral 10-B is shown in Patent Document 9. In 10-A, rails were used, but here, aerial overhead wires are used instead. The overhead wire is installed at a high position, and the wire connected to the traveling body is hung on the overhead wire with a pulley. The overhead wire plays a role of guiding the movement of the traveling body. The overhead wire is also a hindrance in space, and the longer the wire, the more the traveling body may shake. There are inconveniences such as the trouble of hanging a pulley on the overhead wire at a high position, and the easy-to-hang one is easy to come off. It does not support.
Reference numeral 10-C is that shown in Patent Document 9. It is a running body with wheels that hold the guardrail so that it can move along the surface of the guardrail, and since the running body has no other wheels between it and the ground, the weight of the mowing machine tilts the running body. On the other hand, in order to prevent this, the structure of the wheel holding the guardrail must be complicated and heavy, which is expensive and at the same time has the disadvantage that it cannot be used without the guardrail.

And the gripping means are slidable with each other.
This will be described below with reference to the figure.

FIG. 1 is a diagram showing an embodiment of the ridge slope grass treatment apparatus of the present invention.
In 1-A, the grass treatment means 110 is on the ridge slope because it is shown in the used state. The grass treating means 110 has a so-called mowing function, a function of collecting cut grass, a function of treating grass and the ground, and other functions. The guide means 120 lifts and supports the grass treatment means 110 up to the ridge. The guide means 120 supports the grass treatment means 110 so that it can slide above or below it, or installs the grass treatment means 110 at the tip of the guide means 120 to expand and contract the guide means 120 itself. The grass processing means 110 can be hung under the guide means 120, and various configurations are possible. A support 130 is installed on the upper part of the ridge slope and the upper side of the ridge. In the example of the figure, the support 130 shows a wire fixed to a fixed strut fixed to the ground. Instead of wires, it can take the form of rails fixed to the ground. In the example shown in the figure, an intervening means 140 exists between the guide means 120 and the support 130, and the intervening means 140 is movably gripped by the support 130 by the gripping means 150. The support 130 is strong enough to support the weights of the grass treatment means 110, the guide means 120, and the intervening means 140. The intervening means 140 can take the form of a ridge moving machine capable of self-propelled movement, for example. It is also possible without the intervening means 140. In this case, the gripping means 150 is directly located at the tip of the guide means 120, and the gripping means 150 is movably gripped by the support 130. In the example of this figure, the intervening means 140 has an inclination adjusting means for adjusting the inclination of the guide means 120 and feeding the guide means, and a guide vertical feeding means. The inclination adjusting means and the guide vertical feeding means will be described with reference to FIG.
In 1-B, the difference from 1-A indicates that the guide means 120 has an expansion / contraction function. It can be expanded and contracted by driving from the intervening means 140 side, and as a result, the position of the grass processing means 110 in the vertical direction on the ridge slope can be changed.

FIG. 2 is a diagram showing an embodiment of an example of using the ridge slope grass treatment apparatus of the present invention.
The guide means 120 between the grass processing means 110 and the intervening means 140 or the support 130 may be a rod-shaped body or a wire body. 2-A is the former and 2-B is the latter.
First, in 2-A, in (a), the grass processing means 110 and the intervening means 140 both have a moving means and can move while controlling the movement amounts of both of them to be the same. In this case, they move each other. No stress is applied to the connecting part. On the other hand, in (c), only the intervening means 140 has the moving means, the grass treating means 110 is only pulled and moved, and the grass treating means 110 moving on the grass is delayed. There is an inconvenience that stress is applied to the joint between the two and the joint is broken. In (b), only the grass processing means 110 has a moving means, but the connection with the support 130 is only the gripping means 150, and since it is movably attached, not only stress is not generated but also it is almost delayed. There is no such thing. Therefore, it can be used only in the cases of (a) and (b). In the case of (a), as a means of adjusting the amount of movement, the other position may be observed and adjusted with a camera, or the stress may be measured with a stress sensor and controlled so as to always be below the permissible range. Good. In 2-B, in (d), the grass processing means 110 and the intervening means 140 both have a moving means, and the moving amounts of both can be controlled to be the same. In (e), only the grass processing means 110 has a moving means, but the connection with the support 130 is only the gripping means 150, and since it is movably attached, not only stress does not occur but also a delay occurs. However, work is possible. In (f), there is a case where only the intervening means 140 has a moving means, the grass treating means 110 is only pulled and moved, and the grass treating means 110 moving on the grass is delayed, so that the grass treating means 110 Movement becomes unstable. It is inconvenient compared to (d) and (e).
(A) and (D) are similar and convenient, and then (B) and then (e) are less convenient. (C) and (f) are not desirable.

FIG. 3 is a diagram showing an embodiment of another use example of the ridge slope grass treatment apparatus of the present invention.
In 3- A, the guide means 120 is set at a position higher than the plant height, and the grass processing means 110 is suspended and grounded on the ridge slope. In this case, even if the intervening means 140 moves and the guide means 120 moves at the same time, there is no possibility that the guide means 120 hits the undergrowth. If the guide means 120 is low, it hits the undergrowth and interferes with movement. In this case, the process is to mow all the grass in the vertical direction and then move it sideways, and then move it up and down and then move it sideways.
In 3- B, the grass processing means 110 is attached to the tip of the guide means 120. In (top) and (bottom)
This is the difference in the vertical position of the grass treatment means 110. When the tip of the guide means 120 is attached to the tip of the guide means 120, it does not hinder even if the guide means 120 is lower than the plant height, so that the guide means 120 can move not only in the vertical direction but also in the horizontal direction. That is, after processing a horizontal row, it is possible to move downward by one span and repeat the horizontal processing.
The degree of freedom in the treatment method differs depending on the positional relationship between the guide means 120 and the grass treatment means 110.

FIG. 4 is a diagram showing an embodiment of a gripping means of the ridge slope grass treatment device of the present invention.
An example of the gripping means 150 to the support 130 is shown.
In this example, the wire is used as the support means 130, and there are a wheel 410 that rotates on the wire and a wheel support 420 that rotatably supports the wheel, and the wheel support 420 includes the intervening means 140 or the intervening means 140 or. The guide means 120 is connected. In 4-B, the number of wheels 410 is one, but in order to grip stably, it is better to have three or more wheels as in 4-D. The gripping means 150 has a wheel 410 and a wheel support 420.
When the support 130 extends over a long distance, especially when the support 130 is a wire, a fixed support 160 may be interposed in the middle so as not to loosen due to pulling. In that case, the fixed support 160 may be interposed. At the position of, a mechanism for movably catching the wheel 410 of the gripping means 150 is required, and it is configured as 4-C corresponding to one wheel of 4-B and 4-A corresponding to three wheels of 4-D. Will be done. Both 4-A and 4-C have a rotary coupling portion 430 capable of varying the inclination angle of the wheel support 420. In 4-E, the fixed column 160 and the supporting means 130 are shown in a perspective view.

FIG. 5 is a diagram showing another embodiment of the gripping means of the ridge slope grass treatment device of the present invention.
This is an example of the gripping means 150 that is convenient when the supporting means 130 is a wire, and the gripping means 150 can easily slide along the supporting means 130 by having the rotating means. In 5-A, the gripping means 150 has a pipe shape through which a wire is passed, and has a large number of ball bearings 510 on the inner surface of the pipe. In 5-B, a large number of cylinders are rotatably attached instead of the ball bearing 510. In 5-C, there is a rotating body between the cross sections U or Y, and a wire can be passed between them. Its cross section is shown in 5-D. Both have low sliding resistance due to rotation and can be easily moved. Moreover, the original function of fall prevention can be exhibited.

FIG. 6 is a diagram showing another embodiment of the gripping means of the ridge slope grass treatment device of the present invention.
4 and 5 show a case where the support means 130 is a wire, but FIG. 6 shows a case where the support means 130 is a rail body. The gripping means 150 can be moved while being entwined with the supporting means 130.

FIG. 7 is a diagram showing an embodiment of a guide means and a guide gripping support support means of the ridge slope grass processing device of the present invention.
It is fixed to the gripping means 150 or the intervening means 140 connected to the gripping means 150. For example, when the first columnar body 710 is installed on the intervening means 140, the first columnar body 710 is erected and fixed to the intervening means 140.
A second columnar body 720 is stretchably fitted in the first columnar body 710. A connecting jig 740 is rotatably attached to the second columnar body 720 via a rotating shaft 730, and a guide means can be connected to the connecting jig. The above is the configuration of the guide gripping column means.
The guide means is connected by a connecting jig, and a stretchable part is attached to the guide means. Expansion and contraction can be controlled by a motor and pulleys. It should be noted that these configurations can be configured without being particular about the configurations shown in the drawings.

As a grass treatment means that can be used in the ridge slope grass treatment apparatus of the present invention,
You can use a mower, one that not only cuts but also subdivides, and one that treats grass and other grass-related objects. In the case of a mower, there is a rotary blade at the tip, the blade is supported by a support rod, and the rotation of the blade, the direction of the support rod, etc. are controlled by the controller on the control house side. As the grass treatment means itself, a conventionally used proposed one can be used.

As described above, the ridge slope grass treatment apparatus according to the present invention can prevent the equipment on the ridge from falling due to being pulled by the grass treatment apparatus working on the ridge slope and the guide means, and is therefore extremely convenient for industrial use.
