Abstract

Official abstract text for this publication.

A grass cutter is provided with a duct which extends in a conveyance direction of grass clippings and has a conveyance path for the grass clippings formed inside of the duct; and a duct opening/closing lid provided with a turning shaft which is disposed on the outer side of the duct, and a closing plate which is turnable around the axis of the turning shaft and opens and closes the conveyance path by turning.

First claim

Opening claim text (preview).

What is claimed is: 1 . A grass cutter comprising: a duct extending in a conveyance direction of grass clippings and having a conveyance path for the grass clippings formed inside the duct; and a duct opening/closing lid includes a turning shaft disposed on an outer side of the duct and a closing plate turnable around an axis of the turning shaft, the closing plate opening and closing the conveyance path by turning. 2 . The grass cutter as claimed in claim 1 , wherein the turning shaft is disposed substantially perpendicular to the conveyance direction for the grass clippings. 3 . The grass cutter as claimed in claim 1 , wherein the duct includes a side wall covering the conveyance path from a lateral side, and the turning shaft is disposed along an outer face of the side wall. 4 . The grass cutter as claimed in claim 2 , wherein the duct includes a side wall covering the conveyance path from a lateral side, and the turning shaft is disposed along an outer face of the side wall. 5 . The grass cutter as claimed in claim 1 , wherein the duct includes a bottom wall covering the conveyance path from a lower side, and the closing plate is disposed in such a manner that a lower end of the closing plate is separated from an inner face of the bottom wall when the conveyance path is closed by the closing plate. 6 . The grass cutter as claimed in claim 1 , wherein an upper end of the closing plate is bent in a direction opposite to the conveyance direction of the grass clippings when the conveyance path is closed by the closing plate. 7 . The grass cutter as claimed in claim 1 , further comprising a link mechanism turning the closing plate. 8 . The grass cutter as claimed in claim 7 , wherein the turning shaft is turnable around the axis of the turning shaft, the closing plate is coupled to the turning shaft so as to turn in conjunction with turn of the turning shaft, and the link mechanism is coupled to the turning shaft. 9 . The grass cutter as claimed in claim 8 , wherein the duct includes a bottom wall inclined with respect to a horizontal direction, and the turning shaft is substantially perpendicular to the bottom wall. 10 . The grass cutter as claimed in claim 9 , wherein the link mechanism is coupled to a lower end of the turning shaft. 11 . The grass cutter as claimed in claim 8 , wherein the link mechanism includes a coupling member fixed to the turning shaft, and an operation unit coupled to the coupling member, the operation unit moving to allow the coupling member to turn around the axis of the turning shaft. 12 . The grass cutter as claimed in claim 11 , wherein the operation unit reciprocates in a right-left direction. 13 . The grass cutter as claimed in claim 11 , wherein the link mechanism includes a biasing unit directly or indirectly applying a biasing force to the closing plate so that the closing plate is maintained with the conveyance path open. 14 . The grass cutter as claimed in claim 11 , wherein the link mechanism includes a lock mechanism directly or indirectly locking the closing plate so that the closing plate is maintained with the conveyance path closed. 15 . The grass cutter as claimed in claim 11 , wherein the link mechanism includes a biasing unit biasing the operation unit so that the closing plate is maintained with the conveyance path open, and a lock mechanism locking the operation unit so that the closing plate is maintained with the conveyance path closed. 16 . The grass cutter as claimed in claim 15 , wherein the lock mechanism includes a first lock member formed on the operation unit, and a second lock member abutting against the first lock member when the conveyance path is closed by the closing plate to prevent movement of the operation unit in a biasing direction caused by the biasing unit. 17 . The grass cutter as claimed in claim 16 , wherein the second lock member is formed in a plate-like shape whose faces are perpendicular to a movement direction of the operation unit and includes a through hole allowing the first lock member to pass from one face side to the other face side of the second lock member when the operation unit moves. 18 . The grass cutter as claimed in claim 11 , wherein the operation unit is disposed in a manner to align a longitudinal direction of the operation unit with a right-left direction and includes a grasping portion formed on an outer side in the right-left direction. 19 . The grass cutter as claimed in claim 18 , wherein the link mechanism turns the closing plate so as to open the conveyance path by the closing plate when the operation unit moves in a first direction for separating the grasping portion from the duct, and turns the closing plate so as to close the conveyance path by the closing plate when the operation unit moves in a second direction opposite to the first direction. 20 . The grass cutter as claimed in claim 18 , wherein the grasping portion extends in a direction orthogonal to a movement direction of the operation unit.
