Even if the brush cutter is used for a long period of time, it is less fatigued and eliminates vibration, resulting in higher efficiency. . [Structure] Welding flat steel plates or connecting them with bolts and screws, etc., and by operating the handle, both the brush cutter and the auxiliary device can be integrated, and the grounding part of the brush blade can be adjusted to the ground so that the grass can be cut by yourself It can be moved like cutting.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a device to be attached to a brush cutter used for harvesting weeds and the like, and is a device that can be used by putting the brush cutter fixed to the shoulder and waist with an auxiliary device.

[0002]

[Prior art]

 In the past, the work was done by hanging the weight on the operating rod of the central part of the brush cutter with the shoulder strap and fixing it with the waist strap. Besides, although there was a device such as a moving wheel, there was no mechanical device that could substitute a person's shoulder or waist.

[0003]

[Problems to be solved by the device]

 The present invention intends to increase the work efficiency by putting the full weight of the brush cutter on the auxiliary device and freely operating the brush cutter with the auxiliary device replacing the shoulders and hips of the person that had been loaded until now. thing.

Immediate adaptation to slopes and unevenness of the ground surface.

(5) To simplify the attachment and detachment of the fixed frame and the grip of the operating rod of the brush cutter.

Preventing fatigue while using the brush cutter and danger while working.

When a moving device is used, it is possible to solve difficult problems such as forward and backward turning, left and right turning, and lateral rolling.

[0008]

[Means for Solving the Problems]

 This auxiliary device uses steel plates instead of steel pipes, and by connecting them with bolts and thumbscrews, it facilitates the movement of the inclination angle performed between the flat plate and the support plate, and the support plate and the expansion plate are used. The height of the fixed frame can be easily adjusted.

When the axle and the flat plate are welded, the expansion plate and the fixed frame are welded, and the assembly is performed as shown in FIG. 1 to form the perspective view of FIG. 6, the force applied to the steering wheel 9 moves the auxiliary device. You can freely operate the brush cutter.

[0010]

[Action]

 In this auxiliary device, the expansion plate and the fixing frame are welded together, and the axle and the flat plate are welded together, so if the support plate and expansion plate are fixed with bolts and screws, the whole becomes one solid and is added to the handle. The auxiliary device can be moved like a person's body with the force.

[0011]

【Example】

 Fig. 1 is an assembly view from the front, but the wheels are bicycle wheels and the friction on the ground surface is reduced, and the wheels have a radius of 18 cm or less. If the wheels are small, it is easy for stones and roots to get caught. If it is large, the strut plate will get caught on the wheel when it goes over 30 degrees on a sloping ground, as shown in Fig. 9. If the width of the vehicle is 40 cm from the center of the left and right wheels to the center, the vehicle will not roll over to 10 degrees on a sloping ground without modifying the support plate.

The axle 1 is welded to the flat plate 2 as a flat steel plate except for the axle of the wheel portion.

As shown in FIG. 9, if holes of 7 mm are opened in the flat plates 2A, 2B, 2C, and 2D, and the holes of the 3 support plates 3K are sequentially moved and connected by bolts and screws, it is possible to cope with the sloped ground in 10 degree angular increments and the support plates are formed. You can keep it vertical. Therefore, the support plate can be kept vertical even on a slope of 30 degrees. If it is combined with the angle that can correspond to the inclination described in the previous stage 00 11 it will not roll over to 40 degrees.

As shown in FIG. 1, the hole 3A from the horizontal center point of the axle is lowered to the position 2E in order to prevent overturning. Correspondence comes out.

In the 5 fixed frame, the grip of 7A of the operating rod of the brush cutter is fixed to the rubber product at both ends with steel rings, so the grip can be moved back and forth by removing the rings. By aligning the center of gravity of the bush cutter and fixing it with a fixed frame, the center of gravity of the bush blade and engine can be balanced, and the bush cutter can be operated lightly.

As shown in FIG. 5, the 5 fixing frame has 5 A, 5 B, 5 C and 5 D windows opened and 7 A is fixed with two bands, so that the mower operating rod can be connected to the two handles shown in FIG. The brush blade can be moved as illustrated.

5 Since the central portion of the bottom side of the fixed frame is slightly raised, the operating rod 7 can be moved slightly up and down.

In order to adjust the height of the fixed frame by moving up and down the fixed frame 5 supported by the elastic plate 4, as shown in FIG. 1 and FIG. 3, 3A, 3K, 3B, 3C, 3D are attached to the three support columns. 3E, 3F, 3G, 3H, 3I each have a 7 mm hole, and the expansion / contraction plate has 4A, 4B, 4C, 4D, 4E, 4F, 4G, 4H a 7 mm hole, as shown in FIG. In the case of the lowest height, connect the holes of 3B and 4A in the lower tier and the holes of 3I and 4H in the upper tier with bolts and thumbscrews to fix them. To reach the highest height, lower tiers should be 3H and 4A and upper tier should be You can fix the holes of 3I and 4B by connecting them with bolts and thumbscrews. The height of the fixed frame can be adjusted by combining the holes of the four strut plates and the five expandable plates, and the height of the handle can be adjusted to the height as shown in FIG.

As shown in FIG. 6, the 9-handle passes through the side of the 10-engine and goes out to the rear, so that the influence of exhaust gas is small and the center of gravity is placed on the auxiliary device, so that the brush cutter can be operated by hand.

[0020]

[Effect of device]

 The greatest effect of the present invention is that it moves by human power until now, it has weight on the shoulder of the person, it is fixed on the waist and the operating rod is pulled to the right waist, and the engine is located near the rear of the right waist. Both the operating rod and the engine are far away from the body, and only the handle is at the tip of the hand, the physical strength is not consumed much, the exhaust gas is also far, the bush blade is far, and the danger is also reduced. Is.

The time for mounting the brush cutter on the five fixed frames is fast because two bands are used.

Since the change of the inclination angle and the upper and lower portions of the fixing frame are combined with the holes, the bolt screws and the thumb screws, the work is quick.
