Abstract

PURPOSE:To readily float and discharged mowed grass to the outside in a mower equipped with a rotary reaping blade covered with a top cover and side covers by making the lower edge of the side covers lower than the rotary reaping blade and providing the lower edge with an suction opening. CONSTITUTION:A driving shaft 1 in the vertical direction as a center is protrusively provided with rotary reaping blades 2 and the top and the outer sides of the rotary reaping blades 2 are covered with a top cover 3 and side covers 4 to constitute a mower 7. In the operation, the lower edge 5 of the side covers 4 is made lower than the rotary reaping blades 2 and the lower edge 5 is equipped with plural suction opening 6. An engine 9 is started, the mower is traveled on grass while driving the rotary reaping blades 2. The open air is taken from the openings 6 and cut grass is flown and discharged through a discharge air path 14 to a bag.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a device for facilitating the discharge of grass clippings from a lawn mower.

This invention attempts to discharge the grass cut by the rotary cutting blade to the outside with little force, and when discharging the grass, outside air is sucked in from the opening at the lower edge of the side cover that covers the outside of the rotating cutting blade. and related to those attempting to discharge turf grass in a floating manner.

[Prior Art] In the conventional cutting blade, the lower edge of the side blade bar covering the outer side of the rotary cutting blade is flat, and this lower edge is in contact with the turf over the entire circumference.

[Problem to be Solved by the Invention] When this kind of conventional cutting blade cuts the grass with a rotary cutting blade and attempts to release the grass to the outside, the cutting operation is carried out using a top cover and a side cover. Since it is difficult for outside air to be taken into the space where the weeds are removed, weed removal performance deteriorates due to rotation, and engine speed decreases.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned problems of the conventional device, and takes the following technical measures.

That is, rotary cutting blades 2, 2 are provided protruding in the radial direction with the vertical drive shaft 1 as the axis, and the upper and outer sides of the rotating cutting blades 2, 2 are connected to the upper cover 3 and the side. In a lawn mower covered with a side cover 4, the lower edge 5 of the side cover 4 is connected to the rotary cutting blade 2.
, 2, and a plurality of intake openings 6, 6, . . . are provided in the lower edge 5.

[Effects of the Invention] With the above-described configuration, the present invention provides the following technical effects. That is, when the rotary cutting blades 2, 2 cut the grass and release the grass to the outside, the lower edge of the lateral force bar 4 is placed in the space covered by the upper cover 3 and the side covers 4 where the cutting operation is performed. Since the outside air is sucked in through the air intake openings 6, 6, .

[Examples] Examples of the present invention will be described in detail below by way of example with reference to the drawings. However, the dimensions, materials, shapes, relative arrangements, etc. of the component parts described in this example are not intended to limit the scope of this invention to only those, unless there is a specific description. , is merely an illustrative example.

The rotating mower is a walking lawn mower 7 in which the structure of the present invention is folded, and the lower edge of the cover of the reaping device is attached to the abdomen of a riding lawn mower (not shown) so as to be movable up and down. You can also fold it into

An engine 9 is mounted on a deck 8, which is a main frame composed of an upper cover 3 and a side cover 4, and a drive shaft 1 protrudes from the engine 9 into the deck 8 below.

Rotary cutting blades 2, 2 are attached to the lower part of the drive shaft 1 to cut grass within a certain rotational diameter, and a side cover 4 is located on the outside of the rotating cutting blades 2, 2, and a side blade bar 4 The lower edge 5 extends further downward and covers it.

At the lower edge 5 of the side cover 4, intake openings 6, 6, . . . are provided at positions lower than the rotary cutting blade 2.

As shown in FIGS. 1 and 2, this frontage 6 is located in the same direction as the rotation direction arrow A of the rotary cutting blade 2,
0. It consists of a diagonal partition wall 10.10 guiding the.

When the opening 6 is oriented diagonally in this manner, foreign objects such as wood chips and stones that are thrown away by the rotary cutting blade 2 are not directly thrown out to the outside.

Reference numerals 11 and 12 denote front and rear wheels, which are arranged at the four corners of the deck 8.

13 is a steering wheel.

Reference numeral 14 denotes a discharge air passage, which extends in one place toward the rear of the deck 8. A mesh air permeable bag (not shown) is attached to the end of this discharge air passage 14 to carry the cut grass. Store it.

[Effect] Next, one effect will be explained.

Start the engine 9, engage the clutch (not shown), and
While driving the rotary cutting blades 2, 2, the lawn mower continues mowing work by traveling on the grass.

The lower edge 5 of the side cover 4 comes into contact with the grass due to the weight of the machine, but outside air is sucked in through the openings 6 and 6, and the cut grass is floatingly discharged into the bag via the discharge air passage 14.

[Brief explanation of the drawing]

The figures show one embodiment of the present invention, in which FIG. 1 is an enlarged bottom view of the main part, and FIG. 2 is a bottom view. FIG. 3 is an overall side view. In the figure, numeral 1 is a drive shaft, 2 is a rotary cutting blade, 3 is an upper cover, 4 is a side blade bar, 5 is a lower edge, and 6 is an opening.

Claims (1)
