Abstract

PURPOSE:To reduce the bulkiness of a recovery bag and eliminate the labor of tying the opening of the bag with a string, by compressing an air- impermeable recovery bag containing mowed grass and welding the opening of the bag to hermetically seal the bag. CONSTITUTION:Mowed lawn grass discharged from a chute 1 is thrown into an air-impermeable recovery bag 4 in a container 3 of a grass-collecting apparatus 2 and pressed with a compression apparatus 5 to discharge the air from the bag 4. A welding apparatus 6 is energized and the opening of the recovery bag is welded with the heaters 12, 13 of the welding apparatus to hermetically seal the bag. The intrusion of air into the recovery bag and the restoration of the bag to its original state can be prevented and the recovery bag keeps the compressed state.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a grass collecting device for a lawn mower.

[Conventional technology]

Examples of grass collecting devices for such lawn mowers include Ll, S, and P.
As disclosed in Patent Publication No. 3,974.631, a collection bag is spread out inside the container body and transported from a mower of a lawn mower (to collect grass clippings one after another, and the bag becomes full after collection). There was one that was configured so that the grass clippings could be taken out at once by narrowing the opening of the collection bag and tying it with a string.

[Problem that the invention seeks to solve]

Although the grass collecting device having the above structure has the advantage of being able to take out all of the collected grass at once, it has the trouble of having to tie it up with a string. Furthermore, the collection bag taken out had the disadvantage of being bulky and having a low density despite its large size.

In consideration of these circumstances, the present invention aims to eliminate the trouble of tying the opening with a string and to prevent the collection bag taken out from the container body from being bulky.

[Means for solving problems]

The characteristic configuration of the present invention is that a container body includes a non-breathable collection bag for collecting the grass clippings conveyed from the mower, a compression device for compressing the collection bag containing the grass clippings, and a compression device for compressing the collection bag containing the grass clippings. A sealing device is provided for sealing the opening of the collection bag to make it hermetically sealed, and its functions and effects are as follows.

[For production]

In other words, the grass clippings conveyed from the mower of the lawnmower are put into a non-ventilated collection bag inside the container body, and when the collection bag reaches a certain amount of grass clippings, the compression device is activated to cut the grass. It compresses the grass and exhausts the air inside the collection bag to the outside. Subsequently, the sealing device is operated to seal the opening of the compressed collection bag, thereby bringing the collection bag into a sealed state. When the bag is sealed, the inflow of outside air into the collection bag is blocked, and the collection bag maintains its compressed state without being restored.

〔Effect of the invention〕

As a result, the hassle of tying the opening of the collection section with a string is eliminated. In addition, even small collection bags can now be packed with grass clippings in a high-density state, making them less bulky and easier to handle.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

Moryo (M) cutting grass on the underbelly of an agricultural tractor (T)
), and a chute (1) for conveying the cut grass cut to the rear and upward during this mole (M) is installed in series, and a grass collecting device ( 2) is attached to the rear end of the agricultural tractor (T), and
It consists of a riding lawn mower.

The grass collection device (2) has two pot-shaped container bodies (3) arranged side by side on the left and right, and distributes the cut grass carried out from the end of the chute (1) to the two container bodies (3). It is structured as follows.

Inside the container body (3), there is a collection bag (4) made of non-porous vinyl for collecting the grass clippings that has been carried out, and a collection bag (4) containing the grass clippings that is placed in the front and back direction. A compression device (5) for compressing the bag and a sealing device (6) for sealing the opening (4a) of the compressed collection bag (4) to seal it are provided.

In detail, a sponge material (7) is spread on the inside of the front surface of each container body (3), a receiving plate (8) is fixed, and a compression plate with a sponge material (9) spread on the inside of the rear surface. (10), and fix the cylinder (Cy) in a front-rear posture to the front of the outer surface of the container body (3), and the cylinder (11)
The tip is forked and fixed to the side part of the compression plate (10). That is, the compression device (5) is configured to move the compression plate (10) forward in parallel with the contraction operation of the cylinder (Cy) to narrow the gap with the receiving plate (8).

In addition, heaters (12) and (13) with heating wires buried along the upper edges of the receiving plate (8) and the compression plate (10) are installed, respectively, and as the compression plate (10) moves to the forefront, Then bend the upper part of the compression plate (10) forward so that both heaters (12) and (13) come into contact with each other. Simultaneously with the contraction of the cylinder (Cy), current flows through the heating wire, and the sealing device (13) heats the heaters (12) and (13).
6).

The collection bag (4) has its opening (4a) folded back outward and is hooked all the way through the heaters (12) and (13), so that the harvested grass transported into the container body (3) can be collected. All of the grass can be stored in the collection bag (4).

When the grass clippings stored in the collection bag (4) reach a certain amount, they are taken out using the following method.

First, the compression device (5) is activated to contract the cylinder (Cy) and move the compression plate (10) forward.

At the same time, the sealing device (6) operates and the heater (12)
, (13) heating begins. When the compression plate (10) reaches the frontmost part, the grass clippings in the collection bag (4) will be compressed to about one-third of its volume, the air will escape, and the two heaters (12) and (13) will come into contact with each other. Then, the opening (4a) of the collection bag (4) is welded. Then, the cylinder (Cy) is extended again to free the collection bag (4) and drop it through the chute hole (3a) formed at the bottom of the container body (3). Incidentally, since the collection bag (4) that has fallen to the ground is in a completely sealed state, there is no inflow of outside air and it does not expand to its original size.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
