The invention relates to a motorized lawn mower.

Ordinary household lawnmowers can handle wet or long lawn grass do not cut properly, the grass will be torn off in a serrated manner unless the lawn is cut frequently.

This phenomenon does not occur if the lawn is cut short is kept and mowed when dry. Furthermore, in the known lawnmowers, the container for the cut grass usually arranged at the front near the ground, so that stooping is required when emptying and reinserting the container. Furthermore, due to the arrangement of the container on the lawnmower, there is no possibility of this container sufficiently to train large, so that there is not enough space for cut grass and when cutting large lawns of the container often has to be emptied. In the same way occurs with the motor. ' powered lawn mower the difficulty of getting a bigger one To fill the container. In addition, there is ■ mow with a vertically arranged cutting device none / Possibility of moving the grass backwards and upwards with enough Promote speed to load a trailer.

The invention has for its object to a lawn mower create that does not have the above disadvantages.

A motorized lawn mower according to the invention is thereby characterized in that a transverse paddle wheel is arranged and driven behind a cutting device for the grass is that the cut grass is conveyed backwards and upwards.

An embodiment of a lawnmower according to the invention will be explained in more detail below with reference to the accompanying drawings will. '

The drawing represents a schematic side view of a lawn mower according to the invention.

The motorized lawn mower has two parallel verticals Side plates 2, of which only one of the side plates is shown in the drawing. Between these panels is at the front of the lawnmower, a horizontal cutting cylinder j5 is arranged, which has the usual cutting 4 and which is in the direction of the Arrow 6 is driven.

A front bottom roller 8 is arranged behind the cutting cylinder J5, and a guide plate 10 is arranged between the roller 8 and the cylinder J> at an angle of approximately 60 ° to the horizontal. The guide plate 10 ends in a cutting edge 11 which cooperates with the cutting edges 4 of the cutting cylinder J> . The guide plate 10 cooperates with an elongated second guide plate 12 which spans the distance between the two side plates 2 and which is inclined at an angle of approximately 45 upwards and backwards from the cutting cylinder J> towards a container 14. The container 14 has a large volume and is arranged in an elevated position on the rear part of the lawn mower. The flow of cut grass is directed between the plates 10 and 12 from the cutting cylinder J> to the container 14. The front end part of the plate 12 is formed in an arcuate shape in an arc 16 which corresponds to the outline of the

Sehneidzylinders 3 corresponds. In the illustrated embodiment, the container l4 is above the floor at a distance of 180 to 220 mm raised and slidable horizontally Out rails, for example below the handles 17 of the Lawnmower can be attached. Between the cutting cylinder 3 and the container 14 is in the conveying path of the mown grass a paddle wheel 18 is arranged which has teeth, blades or blades 20. The paddle wheel 18 is turned in the direction of arrow 22 driven. A rear bottom roller 24 is under the container 14 arranged for the cut grass. The bottom rollers 8 and 24 and the paddle wheel 18 are all between the two Side plates 2 arranged. A drive motor, which is indicated with the reference numeral 26, drives the cutting cylinder 3 via a V-belts 28 and pulleys 30, which are arranged on the outer surface of the plate with. The paddle wheel .18 and the rear bottom roller 24 are driven by the same motor 26 by means of a chain 32 with which the pulley 34 the rear Floor roller 24 drives.

During operation, the cut grass is moved upwards and backwards promoted an angle of about 40 to 60 ° behind the cutting cylinder 3 and becomes the container 14 between the plates 10, 12; directed. The blades 20 of the blade wheel 18 capture here the flow of grass emerging from the cutting cylinder 3 and convey it up and backward at an increased speed. In this way, the flow of grass is brought into the container 14 to the required height. Due to the elevated position of the container 14, it can be emptied without bending over are executed.

To prevent the front cutting cylinder 3 from being in the Soil digs in the event that the ground is somewhat uneven the horizontal distance eiep between the center line of the anterior Bottom roller 8 and the center line of the cutting cylinder 3 very My, compared to the distance su the center line of the front

Bottom roller 8 sized to the center line of the rear bottom roller 24. The rear bottom roller 24 is driven and is used for port movement of the lawn mower. By adapting these spatial relationships, a good cutting effect and Get cutting height for any normal lawn.

In a lawnmower having a cutting cylinder according to this invention, the cutting cylinder J5 cuts the upright ones Blades of grass immediately instead of plucking the grass that has just been pressed down by a yaw movement of the front roller became. In this way, the cutting cylinder is better suited to cutting long and wet grass because the blades of the cylinder grasp the grass in an upright position.

Although above the invention with reference to a lawnmower has been described with a horizontal cutting cylinder, it is also for a lawnmower with a vertical rotating spindle or can also be used for commercial lawn mowers.
