Mowers and Mowers {GRASS COLLECTOR AND GRASS CUTTER}

TECHNICAL FIELD The present invention relates to a grasshopper and a lawnmower, and in particular, it does not release the grass cut by the lawnmower of the lawnmower, but with less resistance, and also suspenders on the shoulder. For example, in accordance with a rocking cutting operation of shaking the mower to the left, it relates to a technique for collecting the cut grass to either right or left.

Conventionally, in a mower equipped with a disk-shaped rotary blade (mowing blade) at its tip, the grass cut by cutting due to the rotation of the rotary blade is scattered by centrifugal force, for example, by hanging the mower on the shoulder by means of suspenders. It is difficult to arrange | cut the cut | disconnected grass by the case of mowing while shaking, etc., and the grass cut | disconnected after mowing was scraped with a rake etc.

However, if the cut grass is left unattended, earthworms multiply and the mole that feeds on it invades, and inclined dung, etc., may cause damage that collapses when rain falls and the collected grass is collected and removed. It is also necessary for the public.

In solving such a problem, as shown in Japanese Patent No. 2931284 shown in Fig. 13, a receiving guide (G) which receives the cutting blade G cut by the rotary blade 1 and guides it to the outside of the rotary blade 1 ( There was to install 2A).

As the pulley guide 2A used a single metal wire as shown in Fig. 13, it was possible to pick up the cutting blade G cut by the rotary blade 1, According to the rocking cutting operation which hangs on a shoulder and shakes a lawn mower to the left side, for example, when the pool which cut | disconnects is to be gathered on the left side, the cutting pool G is easy to slide the pulley guide 2A, and the cutting pool G ) Was difficult to collect in accordance with the cutting operation.

For this reason, as shown in FIG. 14, the focusing tool 2B uses a piece of metal strip board in a vertical plate shape to increase the collection function, and to extend to the rear end side to further increase the collection function. However, it is difficult to stabilize the shape of a single metal strip plate, and in order to achieve stabilization, a large number of mounting stays are required, and the configuration is complicated. Furthermore, by using the metal strip plate in a vertical plate shape, the rotary blade 1 As a result, almost all cutting pools which are cut and released with centrifugal force impinge on the metal strip plate with wind pressure, and the cutting pool G slides and scatters on the metal strip plate, making it impossible to improve collection. It became this cause, and mowing work became heavy, and woman and old man became hard to use.

The present invention aims to solve this problem, and it is sure that the grass cut by the mowing blade of the lawn mower is not released in a simple configuration but can be received with little resistance, and the suspenders are hung on the shoulder, for example, to the left. According to the rocking cutting operation, there is provided a weeding implement and a mower capable of collecting the cut grass well on the left side.
