Description

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

[Conventional technology]

A scale machine has been proposed that rotates two press-contact rolls or two rolls that are press-contacted with an endless belt interposed between the two rolls, and pulls out I'J between the rolls. this! For example, as shown in FIG. 4, a machine body 1 configured to be able to move on the ground by wheels 2 at the front and a tail wheel 4 at the rear is equipped with a rubber roll 6 and an endless belt 14 made of rubber or the like. When the roll 15 is placed in pressure contact with the rubber roll 15 near the ground through the rubber roll 6 and rotated in the direction shown by the arrow, the -■18 is drawn between the rubber roll 6 and the endless belt 14 and removed. It looks like this. In FIG. 4, 7 is a rotating brush for feeding the grass, and 8 is I for s and t pulled out on the endless belt 14.
' A rotating brush for feeding into the N receiver 17, 9 an arm, 10 a fulcrum, and 19 a placket fixed to the fuselage l, which has a hole through which a bolt 12 can be inserted.
'/11 of the spring 11 interposed between the adjusting nut 13
The force causes the arm 9 to be pulled by the port 12, and the rubber roll 6 is brought into pressure contact with the endless bell 14.

In such a weeding machine, the sparrows to be extracted differ depending on how far above the ground hill the pressure contact part between the roll 6 and the endless belt 14 is. The Imperial Palace is located on the ground.

The lowering of the tail wheel 4 is carried out by tightening the support shaft 3, which is threaded on the outer periphery and is inserted into the bladder 2 and 5 fixed to the J11 body 1, with a nut 5'.

[Problem that the invention seeks to solve]

However, in order for this type of weeding machine to be able to move, it is necessary to drive the front wheels, which are the main wheels, and the two rolls, etc. that are in pressure contact with each other, must also be driven. The body is equipped with a driving means such as a gasoline engine. Therefore, the weight of the weeding machine itself is Q.
The machine has a ball of about 150 kg. For this reason, when using a lawn mower with an engine, even if it is used in rainy weather or in wet areas with weak ground, the lawn mower itself may sink, reducing the height of mowing the grass, or causing the lawn to be eaten away. I don't often use a weed cutter to remove weeds, but since it's about three times heavier than a lawn mower, when I use it in the same place as above, the wheels tend to sink, and while it removes weeds, it also removes the grass. There was an opening where the grass was caught in a roll and turned over or damaged the grass, causing it to become rough.

In addition, when the main wheels are rubber tires, if the air pressure is not sufficient, the machine body will move up and down while the machine is running, and the left and right tires will move up and down separately, so the pressure contact point between the two rolls will This shows the disadvantage that weeding is not done uniformly because the weeds move up and down.

[Means for solving problems]

The weeding machine of the present invention has two rolls of a large diameter and a small diameter between the front wheels and the rear wheels of a machine body configured to be movable on the ground, and the contact area between the two rolls is set at a predetermined height above the ground. This is an I-removal machine that holds the two rolls in pressure contact state and rotates the two rolls to pull out weeds, etc., and the front wheel has a large diameter and a wide 10 mm small metal wheel body. A wheel made of a rubber belt layer provided with protrusions, grooves, etc., and characterized in that the rear wheel is a single metal roller-shaped wheel.

The tires used on ordinary tractors, cultivators, etc., as well as automobiles, are larger, and the width of the tire's contact patch becomes larger, but the tire itself has a diameter of 4", which is also commercially available.Therefore, only one tire is used. In the present invention, the wheel body is a flattened part of the rim on which a tire is fitted in the wheel disk of an automobile, and the outer periphery of the wheel body, that is, Instead of tires, a rubber belt layer is fitted or lined on the ground contact surface.The wheel body may be formed into a drum shape, and it is cheaper to use steel as a material, but it reduces the weight. In order to achieve this, it is recommended that the main wheel be made of aluminum alloy or the like.
II with the same tonne as the wheels using lllocm tires.
It can be a wheel of about 130cm.

Moreover, the diameter can also be increased as required. It is preferable to provide two such main wheels at the front and connect both with one shaft.

Similarly, the tail wheel (rear wheel) has a larger diameter than that of a conventional weeding machine, and is a hollow drum-shaped roll.

[Effect]

In the weeding machine of the present invention, since the main wheel is shaped like a wheel disc with a flat ground surface, it is lightweight, and moreover, the ground surface is nJ.
(Main wheel 10) is large, so it can be used in rain or J'I! ! Even in the weakest parts of the board! The weeding machine does not sink and can weed correctly. In addition, the roll diameter of the tail wheel has been increased by 2 times compared to the conventional one.
Because it is more than twice as large, the pressure on the grass after weeding is not strong enough to prevent the grass from becoming flattened, so even if a weeding machine is attached after the tail wheel, the lawn will be mowed correctly.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 6 is a perspective view showing the arrangement of the No.

As can be seen from Figures 1 and 2, two wide main wheels 21 are provided at the front of the weeding machine, and an engine 31 is mounted on a part of the main wheels 21, so the engine, etc. The weight can be supported by the main wheels 21, and the weeding machine can be prevented from sinking. This main wheel 21 is shown in FIG.
As shown in (C), the rubber belt layer 213 provided on the ground surface on the outer periphery may be provided with many small projections as shown in FIG. 3(a), or in the width direction as shown in FIG. It is recommended to provide various types of sliding grooves such as a groove or a helical pattern as shown in (C). Depending on the pattern and shape of this surface, it is possible to climb a slope of about 30 degrees. It is also possible to prevent the +A shredder from slipping even when tilted from side to side.

The heavy wheel main body consists of a disk portion 211 and a rim portion 212, and the shape of the wheel main body can be a single-shaped cross section, a drum shape, or the like, as shown in FIGS. 3(a) to 3(c).

In the lj wheel main body, the disk portion 211 and the rim portion 212 are preferably made separately and integrated by welding or the like. Therefore, the disk portion 211 and the rim portion 212 may be made of different materials.

The two main wheels 21 are attached to one axle 32, and the axes of the two weeding rolls 23 and 24 are parallel to the axle 32, thereby preventing uneven weeding. I can do it.

With conventional lawn mowers, it is difficult to press down the grass after mowing171
However, in the weeding machine of the present invention, a tail wheel with a small diameter is used.
By using rolls with a diameter of about 0.00 am, the weeding machine is prevented from sinking into the ground, and the weeding position is always maintained at the same height, improving the ability to remove the weeds at once. Additionally, even when the lawn mower is attached to the rear, the tail wheel has a large diameter, so even if the tail wheel touches the grass, it will not damage the grass and will easily lift it up, allowing the lawn mower to mow to a uniform height. .

〔effect〕

The ψ scatterer of the present invention consists of a disk part and a rim part, and a rubber belt layer is provided on the outer periphery, instead of the conventional tire.
Since it uses i-wheels, it is possible to achieve a light i'Qi by making the disc part and rim part thinner, and furthermore, unlike conventional tires, the weeding position can be moved up and down due to the deformation of the heavy wheels themselves. You can always stably remove grass at a certain height from the ground. Also, light j
