Description

    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing cuts from being scattered by a brush cutter, and in particular, a brush cutter capable of effectively preventing a cut from a cut object such as grass from being scattered around or wound around a rotary shaft of a brush cutter. The present invention relates to a structure for preventing a cut object from scattering.

  A brush cutter for cutting an object such as grass includes a prime mover, an operating rod connected to the prime mover, a rotating disk-shaped blade, and a safety cover. In such a brush cutter, there is a problem such that a cut object formed by cutting the blade is scattered due to rotation of the blade, or that the cut object is entangled with the rotating shaft or surrounding stones are crushed and scattered. There is a problem that occurs. For example, troubles such as grass scattered in the clockwise direction of the disc-shaped blade rotating counterclockwise, taking time and effort to collect the grass, winding grass around the rotating shaft, etc., causing the prime mover to stop. Also occurs. In addition, foreign matter may be scattered. In order to prevent such problems in the brush cutter, various proposals have conventionally been made. For example, a safety cover peripheral structure for preventing scattering of grass or the like in the direction of an operator located behind the brush cutter (Patent Document 1 below), and a cover for preventing foreign matter scattering by the rotary blade. A doubled one (Patent Document 2) has been proposed, but Patent Document 3 is one that measures the prevention of grass scattering and the subsequent cleaning.

  The essence of the proposal is that the grass cut by the mower is prevented from scattering and the centrifugal force of the cut grass is effectively used to align the rows, and the cut grass is aligned to the left. For the purpose of facilitating cleaning after mowing, a grass receiving guide having a guide portion that receives cutting grass cut by the rotary blade and guides it to the outside of the rotary blade and a mounting portion that can be attached to the mowing machine. And a mower equipped with it.

In some cases. Even in the case of a brush cutter with a variable safety cover position, it is necessary to attach the grass receiving guide and adjust the height of the safety cover in accordance with this, and preparation is complicated.

(Ii) When using the safety cover that is desirable for safety consideration, when the grass receiving guide is composed of a wire rod, the cut grass is entangled with the rotating shaft in relation to the safety cover provided above it. There are inconveniences and dangers that make it easier.

(Iii) When cutting grass that is long to some extent, and this exceeds the height of the strip-shaped grass receiver guide, the cut grass is not collected efficiently in the first place, and the original effect is not achieved. I can't show it.
(Iv) If the height of the strip-shaped grass support guide is increased in order to solve the problem (iii), the mounting position of the safety cover will be increased accordingly, and the operator's field of view is limited, making operation difficult. Become. In the first place, there is a limit to increasing the height of the strip-shaped grass catch guide.

(V) According to the brush cutter with the grass receiving guide, the cut grass is continuously guided to the left of the device and continuously placed in a line on the ground. Compared with the case where it is scattered, the subsequent cleaning / grazing work labor and time will be reduced, but the grass collection work area will be continuously and thinly present. Even if the target area of the grass collection work is discontinuous, it is possible to further reduce the grass collection work in a state where there is a large quantity in one place.

Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is an explanatory view showing a basic configuration of a structure for preventing cut material scattering of a brush cutter according to the present invention. In the figure, this structure is for preventing the cut object from scattering when using the brush cutter that cuts the cut object such as grass and cuts it. A cut object receiving structure 1 for receiving a cut object to be tried and a main body fixing structure 5 for supporting the cut object receiving structure 1 to a brush cutter body 4, the cut object receiving structure 1. Is a guard-like structure provided above the disc-like blade 2 of the brush cutter so as to be a barrier against scattering of the cut material (the invention of (1) above). In the figure, the brush cutter main body 4 is provided with a safety cover 3.

  In the figure, since the structure for preventing cuttings of the brush cutter according to the present invention is basically configured as described above, the guard-like structure of the cutting object receiving structure 1 works as a barrier and is cut and falls down. The cut object to be scattered and moved is received by the cut object receiving structure 1. The cut material is received at the upper edge of the guard-like structure. Thereby, scattering of a cut material is prevented. This acceptance does not necessarily need to be at least temporary placement / holding of a cut object as will be described later, and even if it does not stay at the place, it will at least function as a barrier that hinders scattering movement. It only has to be stopped. However, a configuration in which the “placement / holding of the cut object” can be further performed is more desirable.

  Receiving at the upper edge of the cut object receiving structure 1 has a structure that can support the cut object at least two points from below so that the cut object can be held on the structure 1 at least temporarily. be able to. For example, specifically, a structure using a plate-like material having a substantially horizontal plane portion that can support at least two points in the falling direction of a falling cut object, or a linear material provided so as to cross both the falling directions. The cutting receiving structure 1 can be configured by a double-wire structure or the like. Here, `` at least temporarily '' means that there is no dynamic factor such as flow scattering due to the action of a fluid such as wind, drop due to vibration or tilt of a brush cutter, collapse due to excessive placement of a cut object, spillage, etc. It means that the movement of the cut object is temporarily stopped and held on the cut object receiving structure 1 or the like.

In the figure, the cut object scattering prevention structure is configured so that the cut object receiving structure 1 is substantially rearward in the moving direction of the disk-shaped blade 2 at the time of cutting the workpiece , that is , substantially rearward in the moving direction of the brush cutter body . A cut primary receiving part 1A that serves as a barrier against the scattering of the cut article, and a secondary cut receiving part 1B that serves as a barrier against the scattering of the cut article induced by the rotation of the disk-like blade 2. It is the structure provided (invention of said (2)). That is, when the disc-shaped blade 2 rotates counterclockwise as shown in the figure, the cut primary receiving portion 1A is hooked from the tip of the brush cutter body 4 in the traveling direction (upward in the drawing) toward the right side. The cut material secondary receiving portion 1B is guided by the rotation of the blade 2 at the edge of the blade 2 on the left side in the direction of travel of the brush cutter body 4. It is provided so as to be a barrier against the scattering of cut objects.

  With such a configuration, the above-described structure that can hold the cut object at least temporarily while being placed on the structure 1 is configured. That is, the cut object is supported at least two points from below by the presence of the main body 4 and the safety cover 3 in addition to the cut primary receiving part 1A and the cut secondary receiving part 1B, or in addition to this, and at least temporarily. It can be placed and held on. That is, the cut material is removed by the primary receiving part 1A or the secondary receiving part 1B of the cut object, or by both of them 1A, 1B, or in cooperation with other parts of the brush cutter. Above the disk-shaped blade 2 at least temporarily.

With this configuration, the cut object primary receiving portion 1A serves as a barrier against the scattering of the cut object substantially backward in the moving direction of the disk-shaped blade 2 at the time of cutting the workpiece. Further, the cut object receiving structure 1 does not inhibit the natural fall of the cut object induced by the rotation of the disk-shaped blade 2 in the direction of the blade 2, and the cut object is pushed below the blade 2 or a safety cover is provided. 3 is prevented from entering the space 3 or being caught on the rotating shaft.

  As shown in the figure, in the cut object scattering prevention structure, the cut object secondary receiving portion 1B is provided substantially along the circumference of the disk-shaped blade 2 and has a substantially arcuate shape in plan view. From the workpiece cutting position 2A on the disk-shaped blade 2 to a position with a central angle of 90 °, it can be configured so as not to protrude from the disk-shaped blade 2 (in the above (4)) invention). In the figure, the cut object secondary receiving portion 1B is substantially arc-shaped so as to follow the shape of the disk-shaped blade 2, but this may be a bowl shape having a linear outline. In short, in order to prevent the cut material that is induced by the rotation of the blade 2 from being scattered, the guard-like structure that can effectively receive the cut material that has fallen in the direction of the blade 2 once has an arc shape, a hook shape, or the like. Alternatively, other shapes can be used as appropriate. The central angle 90 ° is an example, and the cut secondary receiving portion 1B can be prevented from protruding to a larger central angle position, that is, a portion closer to the safety cover 3. On the other hand, it is not intended that the present invention exclude a smaller central angle.

  As shown in the drawing, the cut object scattering prevention structure can be configured such that the cut object primary receiving part 1A and the cut object secondary receiving part 1B are continuously and integrally formed ((5 ) Invention).
