Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention comprises a mower in which a plurality of blades rotating around a vertical axis are arranged horizontally in parallel within a housing, and this mower is connected to a pair of left and right blades. This invention relates to a lawn mower that is mounted on the front part of a traveling machine body that has front wheels and rear wheels.

[Conventional technology]

Front mower type lawn mowers, in which the mower is attached to the front of the traveling body, have the advantage of allowing work to be carried out while second-hand monitoring of the work situation, and have been widely used for some time. In such a lawnmower, as shown in Tokai, by arranging the rotational directions of the blades (8) that are arranged in parallel horizontally in the same direction, the cut grass is discharged in the horizontal direction within the housing (9). In addition, a discharge port (12) is provided on the lateral outer side of the housing (9) located on the leeward side of the cut grass discharge wind.

When the cut grass is discharged outward from the side of the machine from the discharge port (12), it is sent to the rear grass collection container (3) through the grass collection duct (13). It is structured so that

[Problem to be solved by the invention]

In the above-mentioned lawn mower, when trying to collect grass clippings by installing a grass collection container at the rear of the machine, the grass collection duct is connected to the discharge port located on the side of the front of the machine, and the grass collection duct is run through this grass collection duct. It must be guided along the outside of the aircraft to the grass container at the rear of the aircraft. However, in order to do this, it is necessary to secure a space in a position where it does not get in the way without crawling through the duct, and the grass clippings that are discharged laterally must be forcefully directed backwards, which tends to cause strain on the feed. , it is often necessary to equip a blower for auxiliary conveyance. In this way, front mower type lawn mowers are convenient for discharging grass clippings laterally, but they are not necessarily suitable for sending grass clippings backwards to collect grass. Ta.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a front mower type lawn mower that can discharge grass clippings not only laterally but also rearward, and that can easily collect grass clippings.

[Means to solve the problem]

In order to achieve the above object, in the lawn mower according to the present invention, the rotation direction of the blades located on both the left and right sides is made inward, and the discharge port of the housing is provided in the middle of the left and right at the rear, and the blade is connected to the discharge port. The duct is passed between the left and right front wheels, and the outlet faces between the front and rear wheels.

[For production]

The cut grass discharge air generated by rotating the blades located at both left and right ends inward collects the grass clippings from both left and right sides of the housing to the front middle, joins them at the front middle, and sends them to the rear exhaust port. To go. It then passes through a duct located between the left and right front wheels and is discharged from an outlet facing between the front and rear wheels. If this outlet is turned sideways, the grass clippings can be released laterally, and if it is turned backward, the grass clippings can be released backwards.

Furthermore, if a grass collection container is provided at the rear of the machine and connected to the supply port, grass collection can be performed.

〔Effect of the invention〕

By applying the present invention, the following effects can be obtained.

■ The duct passes between the left and right front wheels and into the bottom of the aircraft, so it does not get in the way and is convenient in terms of space.

■ Since the exhaust port is formed in the center of the rear of the housing, it is possible to connect the grass collection container in a straight line from front to back using a short duct, allowing for efficient mowing even if the grass discharge is somewhat weak. can be sent to.

■ Also, by changing the direction of the discharge port, it is possible to flexibly respond to side discharge, which discharges grass clippings laterally, and rear discharge, which discharges grass clippings backwards.
