(b) Conventional technology A grass mower that performs cutting work while collecting grass clippings in a grass bag has a grass bag suspended in an open state from a support frame installed on the machine body, and a grass bag is hung at the bag opening of the grass bag. It is constructed in such a way that it is covered with a hopper for feeding grass clippings, and the grass clippings cut by the cutting section are sent from the hopper into the grass collection bag for collection. As described in Japanese Patent No. 204434, there is a structure in which a stopper is protruded from a part of a frame-like frame, and the stopper is fitted and locked into a locking part provided in a mouthpiece of a glass bag, and As stated in Publication No. 62-74516,
A pair of support rods protruding rearward is provided, and a cylindrical body is provided on both sides of the upper end of the grass collecting bag, and is fitted onto the support rods so as to be freely inserted and removed from the rear.

(c) Problems to be solved by the invention In the conventional grass bag hanging structure, when removing the suspended grass bag from the support frame, the entire grass bag must be lifted upwards and the ring-shaped latch removed from the hook. Since the grass collecting bag must be moved laterally after being removed, there is a problem in that a large lifting force is required to remove the heavy grass collecting bag when it is full of grass clippings. Since special fittings for hanging must be provided on both sides, the number of parts increases, making the overall structure complex and increasing costs.

This invention was implemented with the aim of resolving the above-mentioned difficulties, and while the overall structure is extremely simple, the grass bag can be reliably hung and fixed in a predetermined position, and the work of attaching and removing the grass bag is also labor-saving. To provide a grass collecting bag support device that is improved so that the grass collection bag can be used for various purposes.

(d) Measures to solve the problem A grass bag 2 with the bag opening 1 at the top open is hung from the support frame 3 installed on the machine A, and the bag opening 1 of the grass bag 2 is opened. Attach hinge 1 to fuselage A.
In the grass mower, the mower is covered with a hopper 4 which is attached to the mower 4 so as to be openable and closable via the mower 4, and performs mowing work while sending the grass clippings discharged from the cutting part 5 through the hopper 4 to the grass collection bag 2 and collecting the grass. The frame 3 has a substantially shape when viewed from above and opens toward the rear of the fuselage, and is substantially horizontal when viewed from the side, and the support frame 3 is installed at the rear of the fuselage with a smooth upper surface.
The cap 6 of the bag opening 1 of the grass collecting bag 2 is placed and held in a superposed manner on the approximately shaped part of the support frame 3, so that the cap 6 of the bag opening 1 is The hopper 4 is configured to slide on the support frame 3, and the hopper 4 is provided with a locking part 4a that clamps and fixes the cap 6 held in the substantially shaped part of the support frame 3 in the vertical and horizontal directions. The present invention is characterized in that it is a grass bag support device for a grass cutter.

(E) Effect In the grass mower in which the device of the present invention is implemented, if the base 6 of the grass bag 2 is placed on top of the substantially shaped part of the support frame 3, the grass bag 2 can be suspended in an open state. It is held on the support frame 3 in a hanging manner. After setting the grass collecting bag 2 in the above-mentioned state, the hopper 4 is operated to close, and the hopper 4 is placed over the bag opening 1 of the grass collecting bag 2 and pressed with a predetermined force. The locking portion 4a cooperates with the support frame 3 to clamp and fix the cap 6, so that the grass bag 2 is maintained in a fixed state at the desired position.

When the grass collecting bag 2 is hung and fixed in this manner and the mowing work is started, the grass is cut at the mowing section 5.
The grass clippings sent out from the hopper 4 are collected in the grass collecting bag 2. When the grass collecting bag 2 becomes full, the hopper 4 in the closed position is moved open and the grass collecting bag 2 is pulled out toward the rear of the aircraft. moves rearward along the support frame 3 and easily comes off from the support frame 3.

(F) Embodiment An embodiment of the present invention will be described below with reference to the attached drawings.

The mower of this embodiment is a riding type, and includes front wheels 8, 8 that are steered by a steering device 7, and an installed engine 9.
A boarding and operating section 1 consisting of seats, etc. is located on the upper part of the aircraft A, which travels by the rear wheels 10, 10 that are forcibly driven by the
1, as well as front and rear wheels 8, 8, 10, 1
The structure is such that a reaping section 5 is installed in the lower abdomen of the aircraft between 0 and 10.

Although the detailed structure is not shown in the drawings, the reaping section 5 has a reaping blade attached to a reaping drive shaft vertically installed in the center of the bowl-shaped casing, and the reaping blade is interlocked and connected to the mounted engine 9. The cutting blades cut the grass from the grass discharge path inside the casing through the discharge pipe 12 to the hopper 4.
It is configured to send to the department.

The hopper 4, which has a communicating opening on the outlet side of the discharge pipe 12, has its front end connected to a horizontal hinge 14.
The grass clipping bag 2 is attached to a mounting portion 13 at the rear of the fuselage A so as to be openable and closable, and the grass clipping bag 2 is detachably hung from the mounting portion 13 to form a grass clipping collection portion. This hopper 4 also serves to hang and fix the grass collection bag 2 at a predetermined hanging position.

To explain the structure of the grass clippings collecting section in more detail, the mounting section 13 is provided with a hinge 14 for mounting the hopper 4 and a support frame 3 for suspending the grass collecting bag 2.

The support frame 3 has a generally rearward open shape when viewed from above, and is approximately horizontal when viewed from the side. 3, 3 are provided by making the upper surfaces smooth and fixing the front horizontal frame of each substantially shaped portion to the mounting portion 13.

Grass collecting bags 2, 2 are detachably hung on each support frame 3, 3, respectively, and each grass collecting bag 3 has an upper part of a bag formed of a perforated member such as a net. A cap 6 is provided at the periphery of the bag mouth 1 to keep the bag mouth 1 open.

The right and left side portions and the front portion of the cap 6 of the bag opening 1 have a shape that substantially matches the substantially shaped portion of the support frame 3, and when the cap 6 is placed on the substantially shaped portion of the support frame 3, , the entire grass collection bag 2 is held in a suspended state.

Further, the hopper 4 is a cover-like body with only the bottom opened, and when the hopper 4 is rotated to the closed position about the hinge 14 mentioned above, the peripheral wall portion of the lower opening portion closes to the support frames 3 and 3. It is adapted to be placed over the upper circumference of the grass collection bags 2, 2 held in the bag to close the bag openings 1, 1.

A locking portion 4a consisting of a downwardly expanding sloped surface is formed on the peripheral wall of the opening of the hopper 4, and when the hopper 4 is in the closed position, the locking portion 4a is attached to the cap of the hanging grass bag 2. 6 is clamped vertically and horizontally to fix it in a predetermined position.

In addition, as in the example, two grass collection bags 2, 2
When the grass bags are hung in parallel, the locking part 4a of the hopper 4 comes into contact with the front part of the caps of both grass bags and the part of each cap located on the outside of the body of the machine, and at the same time squeezes them. The base parts located inside the machine body are constructed so that they are pressed against each other and the entire body is fixed in position.

In a grass mower equipped with a device configured as described above, the grass collecting bag 2 is simply hung from the support frame 3 and the hopper 4 is closed, and the grass collecting bag 2 is secured to the locking portion 4a of the hopper 4. At the same time, the hopper 4 and the grass collecting bag 2 are brought into communication with each other in the grass feeding state.

Conversely, when removing the grass bag 2 from the support frame 3, the hopper 4 is opened as shown by the phantom line in FIG. 1, and the grass bag 2 is removed from the support frame 3.
Simply pull it out in the direction of the opening of the bag to remove the cap 6 at the mouth of the bag.
It slides on the support frame 3 and can be easily removed.

(g) Effects of the invention In the present invention, the support frame 3 on which the grass collecting bag 2 is hung has a substantially shape in plan view, opens toward the rear of the machine, and is in a substantially horizontal state in side view, and
The upper surface of the support frame 3 is smoothed and installed at the rear of the machine body, and the cap 6 of the bag opening 1 of the grass collection bag 2 is placed and held in an overlapping manner on the approximately shaped part of the support frame 3. In this way, the mouthpiece 6 of the bag opening 1 is configured to slide on the support frame 3, and the hopper 4 for feeding the grass clippings is configured such that the mouthpiece 6 of the bag mouth 1 part slides on the support frame 3, and the hopper 4 for feeding the grass clippings has the base 6 of the bag mouth 1 part slidable on the support frame 3. Since the grass collection bag support device is equipped with a locking part 4a that clamps and fixes the cap 6 in the vertical and horizontal directions, the hopper 4 for feeding the grass clippings can be closed automatically to communicate with the grass collection bag 2. Grass collection bag 2 is fixed in place,
When the hopper 4 is opened to disconnect from the grass collecting bag, the fixed position of the grass collecting bag 2 is released, which greatly simplifies the work of attaching and removing the grass collecting bag 2, especially when the bag is full. When removing the rotten grass bag 2 from the support frame 3, the heavy grass bag 2 can be removed simply by sliding it on the support frame 3 and pulling it out to the outside of the machine without having to lift the heavy grass bag 2. It has the advantage of making it easier to
Since no special parts are required to fix the grass bag 2 in a predetermined hanging position, the overall structure is simple and inexpensive, and when installing the grass bag 2,
There is also the advantage that the operation is simplified because there is no need to align the cylindrical body from the rear with respect to the support rod and insert the cylindrical body.
