Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of scraping grass roots and sieving soil and grass in a storage basket, and removing and weeding the weeds in the furrows of the field and in every corner of the partitioned field.
Machines for tilling fields, and when weeding shallowly such as weeds in the garden, it relates to a small weeder with a motor that can be operated by attaching front wheels.

[0002]

2. Description of the Related Art Heretofore, as this type of weeder, there has been on the market one in which 4 to 5 cutting blades also used as a cultivator are rotated by a prime mover and a handle is operated by both hands, but it is a weedless one. It is a kind of soil that cuts up soil, roots and weeds are left as it is, there is no mechanism to remove it, and eventually there is no method other than manual removal, and the fact is that it is not used much.

Therefore, even today, horse hoe is used for weeding the furrows in the field, and when the above weeding machine is used, there is no other choice but to cover the herbicide later. Removing the weeds that have grown in the furrows during the growing of crops is the biggest problem for the parties, and the roots of small grasses that have been cut off in the soil grow after a single rain and soon become weed carpets.

[0004]

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned deficiencies of the prior art, works well in small turns, and prevents weeds that are densely planted in gardens and other places to be weeded, mainly in the furrows of fields and the corners of divided fields. Completely remove and separate soil and grass, only soil is dropped there and only grass is effectively removed.
Moreover, it has been an object to develop a product that meets all of the needs of a machine that can be provided at low cost and that can be easily operated by a weak person.

[0005]

As means for achieving the above-mentioned object, the present invention has the following constitutional requirements and can be completely solved by combining them. One of the rectangular machine frames is raised upward to form a handle, and front and rear of the machine frame are provided with a floating front wheel and a directional rear floating wheel, respectively, and springs provided on the rear wheel support column The machine frame can be moved up and down, and the front detachable machine frame can be attached and detached with screws.

You can do it. Similarly, there are rear blind fixed columns that are welded on both sides and stand upright, and the rear blind fixed column reinforcing arms that connect the columns to each other at the top and the fixed column and the ring that slides to the rear wheel bearing column are connected. It has a rear blind fixed post support arm that is welded and welded, and the ring has a screw that can be moved up and down.

Further, a bearing for supporting the central crankshaft is provided on the upper portion of the rear blind fixed column, and a storage basket suspension arm connected to the lower weeding storage basket is provided on the crank ring, and the basket is sieved up and down in small steps. The structure In addition, a scraping brush fixing shaft and a plurality of scraping brushes are installed on the front blind fixing column, and weeds and soil that are stuck to the weeding blade are scraped into a storage basket. The weeding machine, characterized in that the weeding blade, the scraping brush, and the drive of the crankshaft are efficiently weeded by the combination of various structures in which the drive motor transmits the drive belt.

The scraping brush has a nylon diameter of 1 m.
A bundle of 80 pieces, each having a length of m, a length of 15 cm, and 6 to 8 wavy peaks per 5 cm, is fixed to a cylinder. One of the weeding blades has a length of about 8.0 cm, has two cuts and a twist, and has a weeding nail at a right angle at the tip.

The weeder according to the present invention not only removes the detachable machine frame at the front part of the machine frame to weed the ridges and corners of the field and cultivates the field, but also removes and attaches the machine frame (both front wheels). It is also suitable for gardening and other shallow weeding, and when arranging every corner of a partitioned field, a left blind and a storage basket can be additionally installed on the left side, and the weed blind is grounded to the extent that soil can be wiped off. Even if the machine frame is pushed down, the clearance between the blind and the ground can be maintained without changing the clearance between the blind and the ground.

The mechanism is an important point of the present invention,
To explain this in detail, the rear wheel bearing support column 7 is not directly fixed to the machine frame 1, but the machine frame fixed support column A welded to the machine frame fixed support column 8 which is welded to the machine frame 1 inside thereof. , A is fixed so as to slidably move in a hole formed on the outside of A, and even if the spring 7-1 of the machine frame 1 is moved up and down, it is not changed.

The up and down movement of this screen is performed by the ring at the tip of the front screen fixing column 9 which is welded to both sides of the weed screen 11.
The height of the weeding blind 11 can be adjusted by loosening the screw attached to the ring at the tip of the rear blind fixing post supporting arm 10-1. Therefore, the weed screen 11 is used for the rear wheel support column 7
In addition, as long as the rear wheels do not sink into the ground, the behavior is separated from the machine frame 1 and the machine frame fixing support 8 with a certain distance from the ground.

The rear wheel bearing column 7 is slidably supported by holes in support plates A, A fixedly installed at two places on the upper portion of the machine frame fixing column 8 welded to the machine frame 1. The scraping brush 25-1, which removes scraped weeds, has a length of 15 cm embedded in a cylinder having a diameter of 1.5 to 2.0 cm.
One piece of nylon having a diameter of 1.0 mm is made up of 80 pieces, and 5 to 10 pieces thereof may be attached. This nylon is not good in a straight shape, and if it does not have 6 to 8 wavy mountains per 5 cm, scraped weeds cannot be wiped off properly. The scraping brush fixing shaft 25 is attached across the front blind fixing column 9.9.

The weeding blade 22 has a saw-tooth notch 23 at two places with a blade crossing of 8 cm. A part of the blade is twisted and a weeding claw 24 is welded to the tip of the blade so that the machine is well advanced and sticks well on the ground. is there. 10 to 20 weeding blades 22 are attached to the weeding blade mounting body 21 with nuts. This weeding blade 22 is a machine frame 1
By pushing down, you can dig into the soil to the desired depth.

[0015]

[Function] This weeder is made to have a functional size for working in the furrows of the field and in every corner of the field. Start the engine and drop the handle of the machine frame with the rear wheel as the fulcrum. For example, the weeding blade moves forward as soon as it plunges into the ground. The number of rotations of the blade may transmit power according to the ratio of the pulleys, and the top and bottom of the handle may be controlled according to the depth of the weed root.

A remarkable feature of this weeding machine is that the weeds installed on the ground are kept in a constant position even when the machine frame is moved up and down so that the weeds can remove soil and weeds scraped off by the weeding blade. Plunge it horizontally into the basket and scrub it off into the storage basket with a scooping brush without leaving them behind. The storage basket vibrates in small steps by the suspension arm connected to the crankshaft at the upper part, the soil is dropped below, and the weeds are left in the basket and separated neatly.

In that case, the frequency and the degree of the mesh of the storage basket to be sieved are determined in consideration of the operating speed, the rotation speed of the crank, and the size of the basket depending on the properties of the soil and the weeds. If the eyes are too big, the soil will drop well, but the grass roots that have been cut into small pieces will also be sifted off, which is undesirable.
The mesh is selected according to the situation. As another configuration, it is also within the scope of the present invention that the basket has a double stitch and is slid and adjusted according to the situation.

When cultivating a field for weeding, remove the detachable machine frame and operate mainly on the weeding blade, and when weeding the garden or other places to be weeded, attach the detachable machine frame at the tip of the machine frame. Driving mainly on the front wheels, weeding can be done shallowly. Speaking of this weeding blade, since there are two notches, it is easy to pick up grasses, and it can be conveniently scratched in a basket. When working with either of them, the distance between the weeding cord and the ground can be freely changed by screwing a ring welded to the tip of the front and rear cord fixing support arms.
