Description

Indication of full grass basket, especially for lawn mowers

Technical field

The technical solution relates to the signaling of the filling of the grass basket especially in the garden lawnmower, consisting of a frame to which the gearbox is connected, the cut grass discharge tunnel and the cut grass basket.

BACKGROUND OF THE INVENTION

The lawn mowers carried on the garden tractor are equipped with various versions of the grass catcher. These devices are usually placed in the basket area, either on the back plate of the machine or at the end of the cut grass tunnel. In both cases, a different percentage of filling of the basket space is achieved, in particular depending on the moisture of the cut grass. In some cases, the cut grass tunnel is also clogged.

The essence of the technical solution

The aforementioned drawbacks are largely eliminated by signaling the filling of the grass basket, especially in the garden mower, consisting of a frame to which the gearbox, the grass clipping tunnel and the basket are connected, according to this technical solution. Its essence is that the bottom of the tunnel is shortened at the point of entry into the basket and a shaft with a switch arm is formed at the plate under the end of the tunnel.

The shaft is preferably formed by a cover, an opening in the back plate and the sides of the hopper and the central part of the hopper. The central part of the hopper may be provided with a sliding screen. The switch is preferably connected to a light and / or audible signal.

The proposed solution eliminates the effect of the cut grass moisture and works independently of the pressure exerted by the cut grass collected. The shorter tunnel bottom prevents the tunnel from clogging. The switch is simple in design, easy to manufacture and maintain. The shaft formed by the cover, the opening in the back plate and the hopper sides and the central part of the hopper creates a suitable space that does not reduce the volume of the basket and at the same time prevents premature discharge of cut grass on the switch. The sliding aperture in the middle of the hopper allows you to change the size of the hopper. Interconnecting the switch with light and / or acoustic signaling simplifies operation and warns of the hopper full in time.

Overview of the drawings

The technical solution will be described in more detail with reference to a specific exemplary embodiment of a grass basket filling signaling with reference to the accompanying drawings, in which Fig. 1 shows an exemplary embodiment in side view and Fig. 2 shows a part of the device in front view.

Examples of technical solution

The lawn mower consists of a frame I to which the gearbox 6 is connected, a tunnel 3 for cutting the grass clippings and a grass clipping basket 2. The bottom of the tunnel 3 is shortened at the point of entry into the basket 2 and a shaft 13 is formed under the end of the tunnel 3 under the end of the tunnel 3. The shaft 13 is provided at its lower edge with an arm 5 with a switch 4. through the opening 14 in the back plate 12 and the side walls of the hopper and the middle part 11 of the hopper.

The middle part JJ of the hopper is provided with a sliding screen JO. The switch 4 is connected to the light and acoustic signals by means of an electric line.

- 1 CZ 9673 Ul

When mowing, the cut grass is conveyed through the tunnel 3 to the basket 2. The cut grass is thrown into the basket 2 in the direction of the arrow 9. When the basket 2 is full, the excess grass falls through the shaft 13, thereby depressing the switch arm 5. sound and light signaling. The sliding screen 10 allows the amount of basket 2 to be filled. The cover 7 prevents grass from settling on the gearbox housing 6.

Industrial applicability

The signaling of the filling of the grass basket according to this technical solution will find application especially in lawn mowers.
