Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a weed cutting device used to cut down weeds growing on the slopes of highways, etc.

``Prior Art'' Weeds grow thick on the slopes of expressways, so they must be mowed regularly. Conventionally, this mowing work has been done using a sickle or a small brush cutter, but in these cases, it is necessary to collect the cut weeds after cutting, and then load the collected weeds into the bed of a car. No. However, these operations require a lot of time and effort.
Additionally, on expressways, work vehicles must be parked on the shoulder of the road, so work must be done as quickly as possible, which requires a large number of workers. .

``Problems to be solved by the invention'' The invention was developed in view of the above points, and it cuts weeds with a rotating blade installed at the tip of a suction tube, and automatically removes the cut weeds. By automatically drawing suction into the tank, it is possible to omit the work of collecting cut weeds and then loading the weeds into the bed of a car. It is an object of the present invention to provide a weed cutting device which is suitable for cutting weeds on sloped surfaces such as expressway slopes by being configured so that the direction of the weed cutting device can be freely changed. .

``Means for Solving the Problems'' The gist of the present invention is to provide a tank that uses a blower to suction and store weeds from a suction pipe as described below;
It consists of a connecting pipe installed upright at the top of the tank and a suction pipe connected to the connecting pipe, and the suction pipe is
a base formed in an L shape and having a vertical portion connected to the connecting pipe so as to be slidable in the vertical direction and rotatable in the horizontal direction; an intermediate portion that is connected in a sub-style manner and is slidable along the axial direction of the horizontal portion of the base portion and rotatable in the vertical direction; and an intermediate portion that is formed in a straight line and enters the other end of the intermediate portion. In addition to making the axially central part flexible and bendable, a rotary blade for cutting the roots of weeds is provided in the opening at the tip, and the weeds are removed in the depths of the rotary blade. A weed cutting device is characterized in that it comprises a distal end portion provided with a crusher for cutting finely.

Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments.

The drawing is an explanatory view of one embodiment of the present invention, and in the drawing, 1 is a tank for sucking and storing cut weeds. The tank 1 is placed on the loading platform of a truck A as shown in the figure. 2 is a blower attached to the tank 1, which connects the tank 1 from the suction pipe described later.
This is for suctioning out cut weeds.

Reference numeral 3 denotes a connecting pipe vertically installed at the top of the tank 1, and is made of a flexible material.

Reference numeral 4 denotes a suction tube, which includes a base portion 4a bent into an L shape, a middle portion 4b, and a straight central portion 4 in the axial direction.
It consists of a bendable tip 4c at c', and has a substantially U-shape as a whole. The connecting portions of the base portion 4a, intermediate portion 4b, and tip portion 4c are telescopic, and are configured to be extendable and rotatable. Further, the vertical portion 4a' of the base portion 4a is fitted into the connecting tube 3, and is slidable vertically and horizontally within the connecting tube 3. Further, in the tip end 4c, a rotary blade 5 for cutting the roots of weeds is disposed at the tip opening, and a crusher 6 for cutting the weeds into small pieces is disposed at the back of the rotary blade 5. has been done.

Note that 5a is a drive motor for the rotary blade 5.
7 is a balance weight. Further, 8 is the suction tube 4
This is a hydraulic cylinder for raising and lowering the piston rod, and is pivotally attached to the top of the tank 1, and the tip of the piston rod 8a is connected to the suction pipe 4.

Further, numeral 9 is a wheel attached to the opening of the tip 4c of the suction tube 4.

"Operation" Next, the operation of the present invention having the above configuration will be explained.

When a worker (not shown) holds the tip 4c of the suction tube 4 and moves it left and right, the rotary blade 5 comes into contact with weeds and cuts them. Blower 2 for cut weeds
and is housed in the tank 1 through the intermediate portion 4b and base portion 4a of the suction tube 4.

Further, the weeds cut by the rotary blade 5 are too long and easily clog in the suction pipe, so they are cut into small pieces by the crusher 6.

Also, when cutting weeds on high slopes,
The hydraulic cylinder 8 may be actuated to raise the base portion 4a of the suction tube 4, and then the intermediate portion 4b may be rotated to swing the tip portion 4c to the top of the slope.

``Effects of the invention'' The present invention has the above-mentioned structure and function, and the mown weeds can be automatically sucked into the tank and stored in the tank. This makes it possible to omit the work of collecting the picked weeds and the work of loading the collected weeds onto a truck. Therefore, the work can be done quickly without requiring a large number of personnel. In addition, since the suction tube is configured so that the direction of its tip can be freely changed,
The tip can be swung at the top of a slope to perform mowing work, making it suitable for mowing weeds on slopes such as highway slopes, and has many practical uses and benefits. There is.
