Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in grass storage means in a mower.

More specifically, we improved the filter box into which the exhaust gas discharged from the mower together with the grass clippings flows, so that the exhaust gas is smoothly discharged to the outside, and the filter box into which the exhaust gas is discharged along with the grass clippings is improved. This invention relates to a grass collection filter box with a storage bag for disposal in a grass mower, which prevents grass from floating around inside the box and allows the grass to fall and be discharged into a storage bag directly below the box.

Conventional lawn mowers generally consist of a grass cutting blade, a fan that discharges the grass cut by the grass cutting blade, and a storage basket that stores the grass discharged by the fan, and when the storage basket is full. When this happens, the bag is removed from the main body, the filled grass is transferred to a dust bag, and then this bag is attached to the main body again for mowing.

The grass collection basket as described above receives the wind power generated by the fan and the cut grass carried by the wind power, and inside this basket, only the wind passes through and is discharged to the outside. The inflowing grass is stored in this basket. That is, this grass collection basket has the function of storing cut grass and the function of letting wind escape to the outside.

Since such grass collection baskets have the above two functions, they often cause inconveniences such as the escape route of the wind being blocked by the grass that tries to escape with the wind, and this blocking also causes There were often problems such as the grass dancing around inside the basket or flowing backwards towards the fan. Particularly, as the grass in the cage gets closer to being full, the ventilation holes in the cage are blocked by the accumulated grass, so the backflow and turbulent phenomena described above become more pronounced.

Further, in conventional devices of this kind, there have been problems such as dust-containing exhaust air that flows into the cage and is discharged to the outside and falls on the operator.

In view of the above-mentioned conventional problems, the present invention was developed by
This invention was developed.

The purpose of this invention is to provide a grass cutting blade, a fan for discharging grass, a guide pipe for guiding the cut grass, and a filter arranged at the outlet of the guide pipe, into which the exhaust gas discharged together with the grass flows. Box and
In a grass mower with a storage bag, which includes a storage bag placed directly below the mower, the outlet end of the guide tube extends horizontally, and the rear surface facing the outlet end of the guide tube of the filter box is a vertical surface. An object of the present invention is to provide a grass filter box with a storage bag for disposal in a grass cutter, in which substantially the entire side wall surface constituting the box is formed of a mesh band.

Therefore, the object of the present invention is to make the outlet end of the guide tube horizontal, and to make the side surface of the filter box facing the outlet end perpendicular to the horizontal, and to By forming the entire surface with a mesh band, the exhaust gas that flows almost horizontally into the box is received by this vertical surface, so that only the exhaust gas can be discharged from this mesh-like vertical surface, and the exhaust gas that flows in along with the exhaust gas can be discharged from this vertical surface. This reduces the kinetic energy of the grass, allowing it to fall downward under its own weight. To enable exhaust gas to be smoothly discharged to the outside, to reduce turbulence and backflow of exhaust gas inside the box as much as possible by the configuration, and to further reduce the filter box facing the worker. To provide a collection filter box with a storage bag for disposal in a lawn mower, in which a part of the wall surface is formed with a shielding band to prevent dust-mixed exhaust discharged from the filter box from reaching the face of a worker. It is in.

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is an overall perspective view of a collecting filter box with a waste storage bag for a grass cutter according to the present invention, Fig. 2 is an overall perspective view of the filter box, Fig. 3 is an exploded view of the filter box, and Fig. 3 is an exploded view of the filter box. FIG. 4 is a perspective view showing the holding portion of the waste storage bag.

Reference numeral 1 indicates a lawn mower to which the present invention is applied, 2 a motor, 3 a running wheel, and 4 a main body. A mowing blade and a fan are arranged at the lower side of the main body 4, and the mowing blade and the fan are rotated by the rotation of the motor 2, so that the grass is cut and discharged to the outside from the opening 4a of the main body 4 by the fan. It's getting old.

The guide tube 5 is vertically erected from the main body opening 4a,
The upper end of the guide tube 5 is curved horizontally backward so that the exhaust gas from the guide tube 5 is discharged horizontally. A grass filter box 6 is detachably attached to this horizontally opened end opening 5a. The guide tube 5 has a long cylindrical shape, and support stays 7, 7 are interposed between the main body 4 and the guide tube 5 as shown in the figure, thereby firmly fixing the guide tube 5 to the main body 4. The grass filter box 6 has a box shape as shown in FIG. 2, and has an opening at the bottom.
FIG. 3 shows a developed view of this box 6 in an expanded state. In FIG. 2, a hole 6a1 into which the opening 5a of the guide tube 5 is fitted is formed in the front surface 6a of the box 6, where the opening 5a of the guide tube 5 faces. The mesh band 10 forms a mesh shape as shown in FIG. The rear surface 6b of the box 6 is a vertical surface as shown in the drawing, and the upper side of this 6b and the right half side of the upper surface 6b, that is, 6c1 in FIG. A corner-shaped shielding portion is formed on the upper side of the shield. The entire other surfaces including the left and right side surfaces, 6d and 6d in FIG. 3, are formed with mesh bands 10, thereby allowing the exhaust gas flowing into the box 6 to pass through smoothly.

The reason why 6b1 and 6c1 shown in FIG. This is to prevent fine particles such as dust from flying in the direction of the driver's face.

The bottom opening of the box 6 has a storage bag 1 for disposal.
1 is placed. A binder-like locking tool 12 is integrally fixed to the periphery of the bottom opening of the box 6, and by locking the open end of the waste storage bag 11, that is, the input port, with this locking tool, the storage bag 11
is removably locked to the box 6.

A pair of arm-shaped handlebars 13, 13 extend diagonally upward and rearward from the rear left and right ends of the main body 4, and the portions of the handlebars 13, 13 that contact the left and right outer sides of the storage bag 11 are curved outward, respectively. and a connecting rod 13a that connects both 13, 13.
The holding portion 14 of the storage bag 11 is formed in the space surrounded by this curved portion.The holding band 15 is loosely attached to the main body 4 from the connecting rod 13a of the holding portion 14. As a result, a bowl-shaped space is formed in this holding part 14, and the lower side of the storage bag 11 is stably held in this holding part 14, that is, this holding space.

Incidentally, 8a and 8b in the drawing indicate irradiation lights, and if the lights 8a and 8b are turned on during mowing work at night or the like, mowing work can be carried out efficiently.

Next, we will discuss the effect.

As mentioned above, the grass cut by the mowing blade is
Exhaust gas generated by the rotation of the fan is guided horizontally from the guide tube 5 to the filter box 6. The exhaust gas flowing in approximately horizontally collides approximately perpendicularly with the vertical rear surface 6b of the filter box 6, but due to the mesh band 10 on this rear surface 6b, only the wind force (exhaust air) passes through this mesh band 10. and discharge it outside. At this time, the grass carried into the box 6 by the exhaust gas has its kinetic energy reduced, falls downward under its own weight, and is automatically stored in the storage bag 11 on the lower side. The above is the main behavior of the horizontally flowing exhaust gas inside the box 6. Since the exhaust gas collides with the rear surface 6b, there is some backflow, but the box 6 according to the present invention As described above, since almost all the side wall surfaces except for a part are in the shape of 10 meshes, the exhaust gas flowing into the box 6 is dispersed in all directions and smoothly flows outside from these mesh bands 10. is discharged. Therefore, turbulent flow or backflow within the box 6 is prevented, and the disturbance of grass within the box 6 caused by this can be reduced as much as possible.

In this way, only the exhaust air carrying the grass is smoothly discharged from the box 6, and the grass falls and is stored in the lower storage bag 11 without being thrown around inside the box. When the storage bag 11 is full, it can be disposed of by tying its inlet.

By the way, during work, most of the exhaust gas from the box 6 is released along with dust from the rear surface 6b, but since the corner-shaped shielding band 9 restricts the exhaust from diagonally upward, Exhaust gas mixed with dust will not be discharged into the face of the worker located at the upper rear.

As is clear from the above explanation, by receiving the exhaust gas discharged horizontally from the guide tube at the vertical mesh band on the rear surface of the filter box, only the exhaust gas that reaches the mesh band can be discharged to the outside. As a result, the grass carried along with the exhaust gas has its kinetic energy reduced within the filter box and stalls, thus making it possible to avoid as much grass as possible from dancing inside the filter box. Since almost all of the sides constituting the filter box are formed with a mesh band, except for a part, the exhaust gas whose mission is to carry grass to the inside of the filter box can be continuously convected inside the filter box. The effects are remarkable, such as the fact that the exhaust can be smoothly discharged, and the above-mentioned disadvantages caused by turbulence or backflow within the exhaust box can be eliminated.

Further, according to the present invention, while exhibiting the above-mentioned effects, the exhaust gas mixed with dust is prevented from falling on the worker's face, especially the worker's face, so it is also useful in that respect.

In particular, according to the present invention, the storage bag is removably locked, so when the storage bag becomes full of cut grass, the full storage bag can be separated from the mower body and disposed of. The practical effects of this type of mower are remarkable, such as the relatively troublesome task of disposing of the grass cut by this type of mower.
