Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turf management device, and more particularly to a turf management device suitable for promoting the growth of turf and facilitating the removal of turf debris.

When it comes to lawn management, a lot of effort goes into keeping the grass at the same height and creating a growing environment so that the grass can maintain its bright green color.

A lawn mower can be used to easily manage a wide range of lawns to keep the grass at the same height, and it is also possible to use a lawn vacuum to suck up the mowed grass debris to keep the two sides in order.

However, if the debris generated during lawn mowing floats on the surface of the lawn, it can be removed with a lawn vacuum cleaner, but if it becomes entangled with the force of the roots of the two stems and accumulates, it is difficult to remove the debris with a lawn vacuum cleaner. Even if the work is carried out, only the grass debris on the surface is removed, and the grass debris that exists between the two stems, so-called satsu, cannot be removed.

If there is a large amount of this grass, not only will the green grass turn yellow as the grass dries up, spoiling its appearance, but the stolons B growing along the surface of the ground will not receive enough light and moisture. , the grass deteriorates because new leaves do not sprout from the branches B.

Also, if you cut the stolons (Lerner) of the grass at an appropriate point, new roots R will grow from the cut point toward the earth G and fix the grass to the ground. If the grass grows too long away from the grass, its adhesion to the ground will be poor, and people walking on the two sides may trip over it. I need.

In order to solve these problems in lawn management, a management device has been proposed that cuts the stolons B of the lawn, but if the grass is not completely removed, the stolons B will be damaged. Even if you make a cut, the two new buds will not be able to grow due to lack of light and water.

Therefore, this invention raises the grass that has sunk near the base of the two stems, which is caused by cutting the stolons of the lawn and mowing the lawn, to the surface of the lawn, and makes sure that the grass can be removed with a lawn vacuum cleaner. It was designed to be obtained.

Hereinafter, details of the present invention will be explained with reference to the accompanying drawings.

First, the drive shaft indicated by reference numeral 1 in Figures 2 and below is supported by bearings at both ends, and at either end there is a drive shaft such as a pulley or sprocket wheel for receiving power transmission from a hydraulic motor or other device. A drive source 2 is attached to the drive shaft 1, and cutters 3 for cutting stolons B of the lawn are attached at regular intervals along the length of the shaft.

A key 1a is formed on the drive shaft 1, and the cutter 3
The brush body 4 is installed between the cutters 3 and 3 along the radial direction of the drive shaft 1.

This brush body 4 has a brush fixing plate 42 between discs 41 and 41.
A single brush 43 whose base is fixed by is attached.

Like the cutter, the brush body 4 has a shaft hole 4a through which the drive shaft 1 is inserted, and is fixed with a key 1a in the direction of rotation of the drive shaft 1.

A suitable spacer 5 is provided between the cutter 3 and the brush body 4 to enable communication between the two, and the drive shaft 1
Near both ends, the cutter 3 and brush body 4 are fixed with bolts 1b to prevent them from moving along the axial direction, and the entire body is covered with a cover 44.

The management device M configured in this manner is supported by a support mechanism 61 and used in order to be towed by a traveling vehicle 6 such as a tractor.

Next, actual turf management using the turf management device according to the present invention will be explained.

First, the pitch of the cutters 3 with respect to the drive shaft 1 determines the length of the grass stolons to be cut, so they are arranged at a desired interval, and the brush body 4 is fixed between the cutters 3.

The drive shaft 1 is driven by a drive source 2 installed at the end of the shaft, so when the cutter 3 hits a stolon B of the lawn, the stolon is cut off when the cutter 3 runs on two sides, and the stolon is then cut off from the cut point. grows toward the ground, and at the same time new buds grow.

Furthermore, since the brush body 4 is fixed to the drive shaft 1, as the drive shaft 1 rotates, the brush body 4 scrapes between the base of the grass, scrapes up the grass to the surface of the grass, and brings it into a floating state. do.

Therefore, when the lawn cleaner is run after that, since the grass is floating on the surface of the grass, all the grass is blown up, leaving two grass-free surfaces.

In the above description, the cutter 3 has a two-blade shape, but it may have a five-blade shape as shown in FIG.

In addition, as shown in FIG. 6, a vacuum car 7 is towed by a traveling vehicle 6 such as a tractor and connected to each lawn management device with a vacuum tank pipe 71, and the grass floating on the two surfaces is removed. It is also possible to draw it up directly into a vacium tank.

As is clear from the above explanation, according to the lawn management device of the present invention, it is possible to cut the stolons of the lawn to an appropriate length, thereby promoting the growth of new shoots and roots, and eliminating the grass that accumulates between two stalks. Since it floats on the surface of the lawn, it can reliably supply moisture and light to the roots and branches of the lawn, which is beneficial in terms of lawn management.

Claims (1)

[Claims] 1 comprises a drive shaft, a plurality of cutters attached to the drive shaft and rotating in a plane perpendicular to the drive shaft, and a plurality of brush bodies disposed between these cutters, and which rotates the drive shaft. This lawn management device is characterized in that it cuts the stolons of the lawn at appropriate intervals and floats the grasses scattered between the two stalks to the surface of the lawn.
