[Industrial applications]

 The present invention relates to a weeding device to be mounted on a riding lawn mower, and more specifically, it is mounted on the rear part of a machine by transporting grass and turf mowed by a cutting blade in a mower deck to the rear with a cylindrical shooter. The collector is trying to collect it.

[0002]

[Prior Art]

 A collector for storing cut grass and grass is generally box-shaped, and this collector is usually composed of an upper cover and a lower storage bag. The upper cover is for opening and closing when checking the amount of grass and grass accumulated in the collector during work, and for checking the clogging of the discharge port of the shutter, and the lower storage bag is for the grass in the collector. When the turf is full, the lower part is opened to release the contents.

For example, a collector a shown in FIG. 5 shows a conventional type collector, and a connection portion with a shooter is not shown, but the collector a is an upper opening / closing cover made of resin. -B and a lower storage bag c formed of mesh or a perforated iron plate, and the air in the collector is installed in the lateral center of the upper opening / closing cover b in order to enhance the carrying capacity of grass and turf. An air outlet e is provided for pulling out.

[0004]

[Problems to be solved by the device]

 In the above-mentioned conventional collector, if the capacity is to be made sufficiently large, the height of the upper cover is inevitably high, and if the upper cover is made large, the rear view is poor and the workability is poor. It had the drawback that

[0005]

[Means for Solving the Problems]

 This invention was proposed in view of the above-mentioned problems, and the following technical measures were taken. That is, in the case where a box-shaped collector 15 for grazing grass and grass cut by the cutting blade 9 rotating in the mower deck 7 is attached to the rear part of the power vehicle, the collector 15 has an upper opening / closing cover. 19 and a lower accommodating bag 20, and the upper opening / closing cover 19 has a low recessed portion at the rear of the seat when viewed from the front, and the left and right side portions thereof are configured to be high. The grass weeding device.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a riding lawn mower, which is equipped with a vertical type engine 3 at the front of a power vehicle 2, and the rotational power of the engine 3 is appropriately reduced by a speed change device in a transmission case (not shown). , That power is transmitted to the rear wheels 4, 4.

A mower deck 7 is mounted between the front wheel 5 and the rear wheel 4 so as to be able to move up and down through a link mechanism 8. Three cutting blades 9 are provided in the mower deck 7 at appropriate intervals in the left-right lateral direction, and are rotated in the same direction (clockwise when viewed from the plane in this embodiment) by receiving power from the engine 3. It is configured. A grass outlet 11 is provided on one lateral side of the mower deck 7, and a resin-made cylindrical guide 12 is attached to the grass outlet 11. Numeral 13 is a shooter which is connected to the guide 12 and conveys grass and grass cut in the mower deck 7 to the collector 15 which will be described later.

Reference numeral 16 denotes a blower case, in which a blower (not shown) for suction and conveyance is housed, and the blower is rotationally driven by an external power taken out from the rear portion of the machine. Grass, turf, etc. sucked by the blower is fed into the collector 15 through the cylindrical body 18. The collector 15 is composed of an upper opening / closing cover 19 and a lower housing bag 20, and has an overall shape of a box. The upper opening / closing cover 19 is configured to be rotatable about a horizontal shaft 22 provided at the rear portion of the collector 15, and the lower housing bag 20 is configured to be rotatable integrally with the horizontal shaft 22. The horizontal shaft 22 is rotated by front and rear arms 23, 24, a link 25 connecting them, an operation lever 26 fixed to the front arm 23, and the like, and the operation lever 26 is moved to the front side. When tilted, the horizontal shaft 22 is rotated clockwise in FIG. 1 via the arms 23, 24, the link 25, etc., and the grass and grass stored in the lower storage bag 20 are discharged. Reference numeral 27 denotes a mechanism for locking or unlocking the opening and closing of the lower accommodation bag 20, which is composed of a rod 29 and a hook 30. When the operating lever 26 is tilted forward, the rod 29 is pulled. The lock 30 is unlocked, and when the operation lever 26 is returned to the original position, the hook 30 hooks on the pin 31 provided on the lower accommodation bag 20 and can be locked.

As shown in FIG. 3, the upper opening / closing cover 19 is configured such that the height of both left and right sides is one step higher than the height of the central portion, and the recess 32 formed in the central portion is the seat 33. There is a recess that allows a worker sitting on the floor to secure enough space to see behind. Vents 36, 36 are formed in the ridges 35, 35 provided adjacent to the concave portion 32, and the passage of cut grass and grass is blocked in the vents 36, 36 to prevent only wind. Wire meshes 37, 37 for passing air are stretched.

Reference numeral 40 in the drawing denotes an exhaust port formed at the lower end of the ventilation passages 36, 36, which is opened downward. In the above configuration, when the lawn mowing work is performed while transmitting the rotational power of the engine 3 to each rotating part, the lawn and grass mowed by the rotating cutting blade 9 are guided from the grass outlet 11 of the mower deck 7 to the guide 12, After passing through the feeder 13, the blower casing 16 is brought into the blower casing 16 and is further lifted up.

When the cut grass and the like in the collector 15 are to be discarded after the mowing work, the machine body is moved to the disposal place, the operation lever 26 is tilted to the front side, and the lower storage bag 20 is rotated. Eject grass and grass. Also, during work, when checking the grass clogging at the end of the cylindrical body 18 protruding into the collector 15 or removing the clogging grass, the operator opens the upper opening / closing cover 19 from the seat 33 side.

[0012]

[Function and effect of the device]

 As described above, the present invention mounts the box-shaped collector 15 for weeding grass and grass cut by the cutting blade 9 rotating in the mower deck 7 to the rear part of the motor vehicle. In this case, the collector 15 is composed of an upper opening / closing cover 19 and a lower housing bag 20. When the upper opening / closing cover 19 is viewed from the front, the portion located at the rear of the seat is depressed low, and the left and right side portions thereof are raised. Since it is configured, it is easy to perform grass and grass mowing work while looking back, and workability is significantly improved. In addition, the upper left and right sides of the collector 15 can be projected upward, so The amount can be increased, and practical effects such as contributing to improvement of work efficiency can be achieved.
