Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a weeding machine used for pulling out weeds at golf courses and the like.

[Conventional technology]

Recently, a weeding machine has been proposed in which the weeding machine rotates between two press-contact rolls, or a roll and an endless belt, or two endless belts, and pulls out the grass by sandwiching it between them. This weeding machine has a machine body 1 configured to be movable on the ground as shown in FIG. 1, for example, and a rubber roll 16 and an endless belt 14 made of rubber or the like arranged so as to press against each other near the ground. , n in the directions indicated by the arrows, the grass 18 is drawn between the rubber roll 16 and the endless bell 14 and is pulled out. In this case, the degree to which the rolls pinch the grass differs depending on the size of the grass and the thickness of the grass, so if both the roll 16 and the endless belt 14 are made of metal, then the grass with different thicknesses It was often observed that when the grass was held between the rolls, the thicker grass could be pulled out, but the thinner grass could not be pulled out because the gap between the rolls was larger due to the thicker grass.

Conventionally, therefore, rubber rolls have been used as described above, but if the elasticity of the rubber rolls is too high, a problem arises in that the rubber rolls catch grass but cannot pull it out.

In order to solve these drawbacks, various elastic bodies have been researched, but all of them can hold thick and thin violet grass at the same time, or a large bunch of grass and a small bunch of grass at the same time. It has not been possible to find a roll that has an elasticity that allows both to be efficiently pulled out at the same time.

[Problem that the invention seeks to solve]

The present invention is intended to solve the above-mentioned conventional problems by 'x%', and it is possible to clamp large grass bundles and small grass bundles at all times, as well as to clamp large grass bundles and small grass bundles at all times. However, the objective is to provide a machine for collecting rolls that can be pulled out in good condition.

[Means to solve all problems]

The present invention is a weeding machine that pinches and pulls out the weeds to be weeded between two rolls or between a roll and an endless belt, as described above, in which the roll is a hollow roll with a fluid such as air inside. It is characterized by what it did.

The hollow roll of the present invention is made of an elastic material such as rubber, similar to tires and the like. As with tires for automobiles, a wheel may be attached to the rotating shaft, and the entire ring-shaped rubber hollow body may be attached to the outer rim of the wheel.

Air is usually used to fill the Mt body into the hollow roll, but other fluids such as water and oil may also be used.

〔Example〕

The present invention will be explained below with reference to Examples.

FIG. 1 shows an example of an apparatus for weeding using a roll 16 and an endless bell 14, which is used as the entire hollow roll 16 of the present invention.

The endless belt 14 is made of a rubber belt or the like, and has two large and small rolls 6.15 running over it. Reference numerals 7 and 8 are brushes, and the front brush 8 has the role of bouncing the removed grains into the weed catcher 17 and cleaning the roll 16tff/cleaner. roll 1
6 is pressed against the endless belt 14 by a support member 9.

FIG. 2 is a side view of main parts showing another embodiment of the present invention.
This is an example of removing leather using a book roll 26.28 ffi.

A hollow roll according to the invention is used as the larger roll 26. In this example, the smaller roll 28 is normally a rubber roll, but the hollow roll of the present invention is used as the large roll 28.
When used as 6, it is used for. Reference numeral 31 is a spring used to press two rolls 26 and 28f: one large and one small. 29 is a grass catcher.

In both FIG. 1 and FIG. 2, the circumferential speeds of the hollow roll and the endless □ belt or the small rolls may be the same or different.

FIG. 3 shows a specific example of the hollow roll 26.
33 is a shaft, 26a is a rubber roll body, 26
b is a rib film provided inside the hollow rubber roll 26 to prevent the surface of the roll from becoming a crown-shaped curved surface. In addition,
Ventilation holes are provided in the rib membrane 26b so that the fluid inside the roll can move freely.

〔effect〕

Since the present invention uses hollow elastic rolls, even if a large diameter grass and a thin diameter grass are sandwiched between the rolls at the same time as in the past, the fluid inside the roll moves and easily grips both. be able to.

Moreover, since the pressure inside the roll is constant, the force that holds each chapter in place does not decrease. Further, according to the present invention, even when grass grows between stones, such as on a beach, the roll is sufficiently dented to cope with the problem, so that it can be easily pulled out. In the above embodiment, a hollow roll is used only as a roll for holding grass, but it may also be used as the small roll 15 of the endless belt 14 shown in FIG. 1, for example. When using the hollow roll of the present invention, there is no need to press the rolls together with strong pressure compared to when all conventional rubber rolls are used.
In addition, since the hollow roll has the same effect as conventional crimping force,
For example, the spring 31 shown in FIG. 2 may be omitted and the two may simply be connected by the arm 30.

In addition to the above, since the present invention uses all hollow rolls, it has various advantages such as not damaging the grass of golf courses.

Claims (1)

[Claims] Rolls and rolls or rolls and an endless belt are arranged near the ground on a machine configured to be able to move on the ground, and grass is sandwiched between the rolls or between the rolls and the endless belt to be pulled out. A weeding machine characterized in that the roll is a hollow elastic roll filled with a fluid such as air.
