Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a grass collecting device that sends grass clippings cut by a mower to a grass collecting section at the rear of a vehicle body using a feeding device driven by an engine. .

(Prior art) A mower is attached to the lower abdomen of a vehicle body such as a small tractor, and a grass collection unit such as a grass collection bag or a grass collection container is placed at the rear of the vehicle body, and the grass cut by the mower is driven by an engine. A system in which grass is sent to a grass collecting section via a conveying duct by a feeding device such as a grass collecting turbine has already been provided and is in practical use. This type of device is convenient for mowing lawns because it can collect grass clippings immediately after mowing and leaves no dead grass behind.

(Problem to be solved by the invention) However, in this type of engine-equipped grass collecting device, the engine and feeding device were conventionally attached to the rear part of the rear wheel of the vehicle body, so the grass collecting part was attached to the vehicle body. I couldn't install it, so I had to make it towable. As a result, the entire device becomes long in the front and back direction, making it inconvenient to mow grass in narrow spaces. In addition, the towed type requires wheels and towing fittings to be provided on the grass collection side as well, which results in high costs.

(Means for Solving the Problems) In view of these conventional problems, the present invention makes the entire structure simple and compact by changing the arrangement of the engine and the feeding device, and also increases the capacity of the grass collecting section. It was provided for the purpose of increasing the size of the vehicle, and its distinctive feature was that the grass clippings cut by the mower were sent to the grass collection section at the rear of the vehicle using a feeder driven by the engine. In the grass collecting device, the engine and the feeding device are arranged on the fender of the vehicle body, and the grass collecting part is attached to the vehicle body.

(Embodiment) Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In Figs. A rear wheel fender 4 is provided. 5 is a steering wheel, and 6 is a driver's seat. 7
is a mower, which has three sets of cutting parts 9 rotatably disposed below a mower deck 8, and the cut grass is moved from the mower deck by the action of a wind-blowing plate formed on the blade of the cutting part 9. 8 One side outlet 8a
is configured to emit. The mower deck 8 is connected to the lower abdomen of the vehicle body 1 by a connection mechanism (not shown) so as to follow the ground.

Reference numeral 10 denotes a mounting frame, which includes a main frame 11 made of a pipe as shown in FIG. 3, and mounting pins 12 and 13 protruding forward from this main frame 11.
, a pedestal 14 protruding forward from one side of the main frame 11 in the left and right direction, and a pair of upper and lower holding parts 15 and 16 protruding rearward from the upper side of the main frame 11
It consists of The lengths of the mounting pins 12 and 13 differ by a dimension L as shown in FIG.
It is inserted into and removed from the rear side. The holding cylinders 17 and 18 are formed with open rear ends in the shape of a flap, and support plate 1 attached to the rear end surface of the vehicle body 1.
It is fixed to 9.

Reference numeral 20 denotes a grass collecting portion such as a grass collecting bag or a grass collecting container, which is detachably attached to the holding portions 15 and 16 of the mounting frame 10. The grass collecting section 20 is entirely or partially mesh-shaped and is configured to allow air to escape to the outside. 21 is a grass collecting turbine device as a feeding device; 22 is an engine for driving the grass collecting turbine device; these are mounted on the pedestal 14 of the mounting frame 10. The pedestal 14 is positioned above the fender 4 when the mounting frame 10 is attached to the vehicle body 1. Integrated turbine device 21
As shown in FIG. 5, the blade body 24 is provided inside a casing 22 and supported by a rotating shaft 23, and the rotating shaft 23 is connected to the engine 22. A first conveyance duct 25 is connected to the casing 22 at the center facing the rotating shaft 23, and a second conveyance duct 26 is connected to the upper side. The first conveyance duct 25 connects the mower 7 and the grass collecting turbine device 21, and has a receiving section 27 attached to the discharge port 8a side of the mower deck 8.
and a flexible portion 28 connected thereto. Second
The conveyance duct 26 connects the grass collecting turbine device 21 and the grass collecting section 20.

In the above configuration, during work, the mower 7 is driven while the engine 22 drives the grass collecting turbine device 21.
The mowing section 9 is rotated, and the lawn etc. are cut by the cutting blade body of the mowing section 9. Then each reaping part 9
The cut grass is sent to the discharge port 8a on one side of the mower deck 8. On the other hand, since the grass collection turbine device 21 is in operation, the grass clippings on the discharge port 8a side are sucked into the first conveyance duct 25, and from this first conveyance duct 25, the grass collection turbine device 21 and the second conveyance duct 26 are transferred. After that, the grass is collected one after another into the grass collecting section 20.

When attaching the mounting frame 10 to the vehicle body 1,
A pair of mounting pins 12 and 13 are inserted into the holding cylinders 17 and 18, and the retaining pins are used to prevent the retaining cylinders from coming off. At the time of this insertion, if a size difference is provided between the mounting pins 12 and 13, it is only necessary to insert one side and then the other, making the insertion easy. Although the engine 22 and the grass collecting turbine device 21 are heavy, by placing them above the fender 4, their center of gravity is located near the top of the rear wheels 3, which improves the weight balance of the entire vehicle. . Also engine 2
2. By arranging the grass collecting turbine device 21 on the fender 4, it becomes possible to attach the grass collecting part 20 to the vehicle body 1, and therefore, the overall length becomes smaller compared to a towed type. The work can be done even in a narrow space, and it can be done easily and inexpensively. Furthermore, in terms of weight balance, the capacity of the grass collecting section 20 can be increased, and in particular, in this case, it is also possible to use the grass collecting section 20 approximately equal to the width of the vehicle.

In the above embodiment, the grass collecting turbine device 21 is used as an example of the feeding device, but the present invention is not limited to this, and any type can be used as long as it can be fed. Moreover, the connection direction of each conveyance duct 25, 26 to the grass collection turbine device 21 can also be changed as appropriate. The pedestal 14 can also be provided on the fender 4 from the vehicle body 1. Further, when using the mounting frame 10, the engine 22 and the grass collecting turbine device 21 may be fixed to the pedestal 14, but they may be detachably attached to the pedestal 14 as a set.

The second conveyance duct 26 is detachably connected to the upper part of the front side of the grass collecting section 20 in the horizontal direction.
This may be connected to the top side of the grass collecting section 20 as shown in FIG.

(Effect of the invention) In the present invention, since the engine and feeding device are placed on the fender, it is possible to attach the grass collecting section to the vehicle body, and the overall length in the front and rear direction can be compared with that of the conventional towing type. It can be made small and can be used even in narrow spaces. It is also structurally simpler than the tow type. Furthermore, the overall weight balance is good, and since the engine and feeding device are located on the fender, the capacity of the grass collection section can be increased.
